Abstract

The utility model relates to a straight lock structure for a sliding door and window, which comprises a first lock seat with a chute and a sliding bar lock arranged in the chute in a sliding way, wherein the first lock seat is provided with an operation hole penetrating through the chute, the sliding bar lock is provided with an up-shifting part and a down-shifting part, the down-shifting part is provided with a locking step, and the locking step is buckled at the edge of the lower orifice of the operation hole. The straight lock structure for the sliding door and window adopts the jacking spring or the V-shaped elastic sheet as a main component for jacking and locking the sliding bar lock, and can ensure the rapid rebound of the sliding bar lock by utilizing the larger deformation stretching amplitude, stronger rebound jacking force and enough jacking height, thereby preventing the phenomena of self-tripping and false unlocking and effectively improving the reliability, durability and safety of the straight lock.

Description

Linear lock structure for sliding door and window Technical Field The utility model relates to the technical field of door and window locks, in particular to a straight lock structure for a sliding door and window. Background In the current sliding door and window application, in order to play a certain anti-theft effect, a horizontal lock is usually installed on the frame of the sliding door and window sash, and the locking effect of the sliding door and window sash after closing is realized through the horizontal lock. The Chinese patent literature discloses a technical scheme with a patent number 202120172613.9 and a name of a novel sliding door linear lock. The horizontal lock of this scheme mainly includes the lock seat that has the spout, slide the sliding bar lock of setting in the spout, the lock seat is equipped with the operation hole that runs through to the spout, the sliding bar lock is equipped with dial portion and dial portion down, dial portion down and be equipped with the locking step that can withhold in operation hole lower orifice edge down, be equipped with spiral shell fragment between dial portion down and the spout, spiral shell fragment comprises spacing portion that integrative curls, inlay dress portion and extension, through spiral shell fragment's elasticity roof pressure, enable locking step to withhold all the time in operation hole's lower orifice edge, make the sliding bar lock play and prevent to loosen, avoid sliding the mistake to open, play the effect of theftproof. However, the linear lock of the scheme has certain defects in the long-term application process, because the sliding bar lock is horizontally laid in the sliding groove by the arc-shaped extension part of the spiral spring plate, the sliding bar lock is jacked up, the locking step is propped against the hole edge of the operation hole, and the aim of locking the sliding bar lock is fulfilled. However, when the arc-shaped extension part of the spiral spring plate is jacked up, the shape design determines that the extension amplitude of deformation can be generated, the rebound jacking force and the jacking height are very limited, and especially when the spiral spring plate is used for a certain time, the extension part is easy to generate metal fatigue so as to cause the elasticity to be reduced, so that the defect that the original rebound jacking force and the jacking height are very limited is further amplified, thereby causing the phenomena of loose release and false unlocking easily caused by the fact that the locking step of the sliding bar lock is not firmly buckled with the hole edge of the operation hole, and further causing the anti-theft performance of the straight lock to be reduced, the durability to be poor, and the reliability and the safety to be poor. Therefore, in view of the foregoing drawbacks and disadvantages of the prior art, the present inventors consider that it is very necessary to optimize and improve the structure of the in-line lock to better meet the application needs of people. Disclosure of utility model The utility model aims to solve the problems and the defects, and provides a horizontal lock structure for a sliding door and window, which adopts a jacking spring or a V-shaped elastic sheet as a main component for jacking and locking a sliding bar lock, and utilizes a larger deformation stretching amplitude, a stronger rebound jacking force and a sufficient jacking height, even if the main component is used for a certain time, a certain redundant space is also reserved when certain metal fatigue occurs, the sliding bar lock can be ensured to rebound rapidly, the phenomena of self-tripping and false unlocking are prevented, and the reliability, the durability and the safety of the horizontal lock are effectively improved. The technical scheme is that the horizontal lock structure for the sliding door and window comprises a first lock seat with a sliding groove and a sliding bar lock arranged in the sliding groove in a sliding way, wherein the first lock seat is provided with an operation hole penetrating through the sliding groove, the sliding bar lock is provided with an up-shifting part and a down-shifting part, the down-shifting part is provided with a locking step, and the locking step is blocked at the edge of a lower orifice of the operation hole. Preferably, the sliding bar lock is provided with a trapezoid clamping groove with a large groove bottom width and a narrow groove opening, the jacking spring is of a spring structure with a large two ends and a narrow middle, one end of the jacking spring is clamped in the trapezoid clamping groove, the other end of the jacking spring is propped against the groove bottom of the sliding groove, or the V-shaped elastic piece is composed of a clamping part and a V-shaped elastic part, the clamping part is clamped with the trapezoid clamping groove, and the V-shaped elastic part is propped against the groove bottom of the slidin
