Description

Door and window linear lock structure with back lock function Technical Field The utility model relates to the technical field of door and window locks, in particular to a straight door and window lock structure. Background At present, in order to enhance the anti-theft performance of the door and window linear lock, a back locking structure is usually additionally arranged on the door and window linear lock. For example, chinese patent literature discloses a patent number 202222727066.3, a technical scheme of "a double-code straight-line lock tool to lock for frame screen window", this scheme mainly includes the lock seat that has the spout, slide bar lock that slides and set up in the spout, rotate two sets of cipher runners that set up in the spout, wherein, the outer wall of lock seat is equipped with the operating hole that is used for controlling the cipher runner, the cipher runner includes the inner wheel, and the cover is established the outer wheel on the inner wheel, the outer wheel is equipped with the password number, the inner wheel is equipped with through-hole and spacing breach, the slider lock is equipped with the protruding pole of taking spacing convex part, the protruding pole wears to establish in the through-hole, and spacing convex part can the activity business turn over spacing breach. When the lock is used, the inner wheel is driven to rotate by stirring the outer wheel, and when the limit convex part of the convex rod is dislocated with the limit notch of the inner wheel, the lock can be closed, and when the limit convex part of the convex rod is coincident with the limit notch of the inner wheel, the lock can be opened. However, in practical application, the following disadvantages exist: Firstly, because this scheme adopts the password runner to realize the switch lock, when using, not only need the user to remember the password, but also need the user to see the password number just can unblank in a short time, can not carry out blind operation for the operation of unblanking is inconvenient enough. Secondly, in order to set up password number, through-hole and spacing breach on the password runner, this scheme needs to split into interior wheel and outer wheel with the password runner to separately make, just so make the structure spare part of password runner increase, increased the application development quantity of mould, the cost is higher, still influences the packaging efficiency of a word lock product. In addition, in order to enable the inner wheel to rotate along with the outer wheel, fixed connection structures are arranged on the inner wheel and the outer wheel respectively, so that the structure of the password rotating wheel is quite complex, and the development and production difficulty is increased. Therefore, in view of the foregoing drawbacks and disadvantages of the prior art, the present inventors consider that it is necessary to optimize and improve the structure of the lock to better meet the application needs of people. Disclosure of Invention The utility model aims to solve the problems and the defects and provide a door and window linear lock structure with a back lock function, which is provided with a back lock thumb wheel with a blocking part, the switch lock can be realized only by forward stirring or reverse stirring the reverse locking stirring wheel, and blind operation can be performed, so that the operation of the switch lock is more convenient. And moreover, the structure of the back-locking thumb wheel is simple, the development and production difficulty is low, and the production and the manufacture are easier. The technical scheme is that the door and window linear lock structure with the back locking function comprises a lock seat with a chute and a sliding strip lock arranged in the chute in a sliding way, and is characterized by further comprising a back locking thumb wheel rotatably connected in the chute, a passing gap for the end part of the sliding strip lock to slide through is formed between the back locking thumb wheel and the chute, a blocking part is further arranged on the back locking thumb wheel, and the blocking part can enter or leave the passing gap along with the rotation of the back locking thumb wheel and form locking or unlocking actions on the end part of the sliding strip lock, and an operation hole for controlling the rotation of the back locking thumb wheel is further formed on the lock seat. Preferably, the back locking thumb wheel is an arch-shaped wheel structure with a flush surface on the back side, and the upper end or the lower end of the back side of the back locking thumb wheel forms a blocking part. Preferably, the utility model further comprises a mounting seat embedded in the sliding groove, wherein the mounting seat is provided with a mounting groove respectively communicated with the operation hole and the passing clearance, and the back-locking thumb wheel is rotatably connected in the mounting gro
