Description

Outdoor mechanical quick-assembling lock Technical Field The invention relates to a plane door lock, in particular to an outdoor mechanical quick-mounting lock. Background At present, a plane lock mounting structure used in the industry generally adopts a pressing plate or cover plate fixing mode, namely, the pressing plate or the cover plate is fixed through one or more screws, and the fixing plate is screwed down under the condition that a screw knife rotates screw threads, so that the fixation between the door lock and the door plate is achieved. The installation is inconvenient, and the quick installation of the plane lock is realized mainly through the inner clamping plates of the fixing blocks and the springs between the inner clamping plates of the fixing blocks, which are symmetrically arranged at the bottom of the base, as disclosed in Chinese patent literature, application number 201910238379.2, application publication date 2019.07.12 and the name of the plane lock. But the stability of the product and the like is poor, the clamping plates at two sides are limited in stress and are easy to be forced to open by external force, and the bottom of the base at the inner side of the cabinet door is easy to be blocked due to the fact that dust enters the fixed block, so that the normal working condition of the clamping plates is affected. Disclosure of Invention In order to overcome the defects, the invention aims to provide an outdoor mechanical quick-mounting lock for the field, so that the technical problems that the stability is poor, the stress is small, the lock body is easily damaged and dismounted by external force, dust is easily entering the lock body, and the normal use is influenced due to the fact that the structural design of the existing similar products is poor are solved. The aim is achieved by the following technical scheme. The utility model provides an outdoor machinery fast-assembling lock, pivot one side base bottom one end of this fast-assembling lock is equipped with fast-assembling mechanism, fast-assembling mechanism includes first spring bolt piece and the second spring bolt piece that both sides symmetry set up to and the oblique tongue piece between first spring bolt piece and the second spring bolt piece for the spring that the oblique tongue piece reset, first spring bolt piece, second spring bolt piece and oblique tongue piece pass through the head apron fixed spacing head piece inslot that sets up in the base bottom, and the installation border of base bottom is stretched out respectively to the one end head of first spring bolt piece, second spring bolt piece and oblique tongue piece to be used for spacing base roll-off door plant mounting hole. The structure design key point is that the first lock tongue block and the second lock tongue block are respectively L-shaped, the bottom and the top of the inclined tongue block are provided with an upper guide groove and a lower guide groove which are crossed up and down and are respectively arranged obliquely, and one end of the first lock tongue block and one end of the second lock tongue block, which faces the inclined tongue block, are respectively provided with a first guide rib and a second guide rib which are protruded inwards; the first bolt block is inserted into the head block groove at the bottom of the base from the bottom of the bolt block, the first guide rib of the first bolt block is inserted into the lower guide groove of the bolt block, the second bolt block is inserted into the head block groove at the bottom of the base from the top of the bolt block, the second guide rib of the second bolt block is inserted into the upper guide groove of the bolt block, one side of the head block groove at the bottom of the base and/or one side of the head cover plate is inserted into the positioning slide hole of the bolt block, and the other end of the bolt block in the head block groove at the bottom of the base is propped against the outer diameter of the base at the inner wall of the head block groove at the bottom of the base or the rotating shaft through a spring. Therefore, the quick-mounting lock improves the existing two-point fixed quick-mounting mode into three-point quick-mounting and fixing mode, improves the clamping plate structure into a block-shaped lock tongue structure, improves the stability of the lock, improves the open slide hole structure into a closed structure, and further improves the stability of the lock. Meanwhile, the quick-assembly lock contracts the lock tongue blocks at two sides in a mode that the head inclined tongue block is pressed, so that quick disassembly is realized. The first lock tongue block, the second lock tongue block and one end head of the inclined tongue block are respectively buckled into one side of the door plate to be inclined to the inclined plane, and the inclined plane length of one side of the inclined plane is larger than that of the other side of the symmetrical
