Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of intelligent locks, and specifically refers to a rear lock structure with quick clamping. Background Art
[0002] An intelligent lock is an actuating component for locking doors in an access control system, which can realize user identification, improve security, intelligent management, etc. With the development of foreign trade intelligent locks, the requirements for the design of foreign trade locks are also constantly increasing. The DIY ability during the installation of foreign intelligent locks is strong. It is possible that a customer buys an intelligent lock and then wants to replace the existing rear lock with another rear lock of an intelligent lock to meet the need for free style matching. At this time, the existing rear fixing plate design will make the replacement limited and inconvenient. Therefore, we propose a rear lock structure with quick clamping to solve the above problems. Summary of the Utility Model
[0003] In view of the above situation, to overcome the defects of the prior art, the utility model provides a rear lock structure with quick clamping, effectively solving the problems that the rear lock structure of the existing intelligent door lock is inconvenient to disassemble and replace.
[0004] The technical solution adopted by the utility model is as follows: A rear lock structure with quick clamping proposed by the utility model includes a fixing plate. Two groups of parallel sliding grooves are provided on the fixing plate. A plastic gear is rotatably connected to the fixing plate. A limiting shaft is fixed on the fixing plate. A plastic switch is rotatably connected to the limiting shaft. A pin shaft is provided below the limiting shaft and is fixed to the fixing plate. A spring is inserted and connected to the pin shaft. Stainless steel buckles are inserted and connected to both sides of the fixing plate. A rack is fixed on the stainless steel buckle and meshes with the plastic gear.
[0005] As an improvement of this solution, there are two groups of plastic gears. One group of plastic gears is a complete gear, and the other group of plastic gears is a symmetrically arranged incomplete gear. The lower group of plastic gears is coaxially arranged with the fixing plate. The two groups of plastic gears are arranged on both sides of the rack.
[0006] As an improvement of this solution, the spring is in a V shape. One end of the spring connected to the pin shaft is rotatably connected to the pin shaft, and the other end of the spring is rotatably connected to the plastic switch.
[0007] As an improvement of this solution, ratchet teeth are provided on the side of the plastic switch close to the plastic gear away from the limiting shaft and are clamped in the gaps of the external teeth of the plastic gear. The stainless steel buckle is in an arc shape, and a rectangular guide bar is provided at one end of the stainless steel buckle symmetric to the rack.
[0008] Adopting the above structure, the beneficial effects obtained by the utility model are as follows:
[0009] This structure can solve the problem of troublesome installation of the rear lock. That is, when dealing with rear fixing plates of different sizes, the rear lock can be conveniently installed, and there can also be corresponding references for national standard locks. After using this structure, to replace the rear lock, only need to open the buckle, align the central hole of the lock, and then tighten the buckle. The buckle will be fixed at the corresponding position of the width of the fixing plate, and it will not be unable to install due to the overly wide width of the fixing plate, improving the flexibility and practicality of disassembly and assembly.

[0013] The drawings are used to provide a further understanding of the present utility model, and constitute a part of the specification. Together with the embodiments of the present utility model, they are used to explain the present utility model, and do not constitute a limitation to the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0015] As Figure 1 and Figure 2 shown, a quick-clamping rear lock structure proposed by the present utility model includes a fixing plate 1. Two groups of parallel sliding grooves 2 are provided on the fixing plate 1. A plastic gear 3 is rotatably connected to the fixing plate 1. A limiting shaft 4 is fixed on the fixing plate 1. A plastic switch 5 is rotatably connected to the limiting shaft 4. A pin shaft 6 is provided below the limiting shaft 4, and the pin shaft 6 is fixed to the fixing plate 1. A spring 7 is plug-connected to the pin shaft 6. Stainless steel buckles 8 are plug-connected to both sides of the fixing plate 1. A rack 9 is fixed on the stainless steel buckles 8, and the rack 9 meshes with the plastic gear 3.
[0016] In order to realize the rapid disassembly and assembly of the rear lock, the plastic gear 3 is provided with two groups, one group of the plastic gear 3 is provided with a full gear, and the other group of the plastic gear 3 is provided with a symmetrical incomplete gear. The lower group of plastic gears 3 is coaxially arranged with the fixed plate 1, and the two groups of plastic gears 3 are arranged on both sides of the rack 9; the spring 7 is provided in a V-shape, and one end of the spring 7 connected to the pin 6 is rotationally connected to the pin 6, and the other end of the spring 7 is rotationally connected to the plastic switch 5.
[0017] The plastic switch 5 is provided with a ratchet on one side of the plastic gear 3 away from the limit shaft 4 and is clamped in the gap between the outer teeth of the plastic gear 3. The stainless steel buckle 8 is arranged in an arc shape, and a rectangular guide bar is provided on the end of the stainless steel buckle 8 symmetrical to the rack 9.
[0018] During specific use, the plastic switch 5 is inserted into the limit shaft 4 and can rotate around the limit shaft 4. By toggling the raised contour on the upper end of the plastic switch 5, it can rotate around the limit shaft 4, and the spring 7 is compressed at the connection with the spring 7 to move closer to the pin shaft 6. At this time, the ratchet end on the plastic switch 5 is pulled out from the outer tooth gap of the plastic gear 3. At this time, the plastic gear 3 can rotate freely, and then the stainless steel buckle 8 is slid open under the guide limit of the slide groove 2 and the plastic gear 3. After aligning the center hole of the lock, tighten the buckle, and use the spring 7 to reset the plastic switch 5 and snap it into the plastic gear 3 to complete the fixation. The above is the use process of the entire quick clamping rear lock structure.
[0019] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
