Description

Technical Field

[0001] This utility model relates to the technical field of floor lock accessories, and more specifically, to a bracket for fixing the lock body of a floor lock. Background Technology

[0002] The Dorma floor lock's fixed lock body bracket is a component used to support and fix the floor lock body. It is usually made of metal and has a certain strength and rigidity to ensure the stability of the floor lock during use, providing a stable foundation for the lock body and preventing the lock body from shifting or shaking during the opening and closing of the door.

[0003] The existing mechanism uses common screws to fix the magnetic suction plate and suction plate bracket to the door. During use, the suction plate is easy to fall off and can be easily disassembled, posing a risk that the suction plate may fall off and injure people or damage other objects.

[0004] A search revealed that Chinese patent CN204266696U discloses a lock body mounting bracket device. In this device, the second screw has a hole in its shank. The second screw passes through the through hole of the suction plate and the first threaded hole of the suction plate bracket, fixing the suction plate to the bracket. When tightened, the end of the first screw can be inserted into the hole on the shank of the second screw, making the second screw stable and less prone to loosening, thus preventing the suction plate from easily falling off. Furthermore, after installation, the first and second screws are on different surfaces. During disassembly, the first screw must be unscrewed first, and then the second screw must be unscrewed to complete the disassembly of the suction plate, increasing the disassembly process and preventing the suction plate from being easily disassembled.

[0005] However, in actual use, the support, as a key component that bears external forces, is prone to fatigue damage, especially in the critical stress-bearing parts of the support, the inner side of the suction plate support and the cover plate, where multiple threaded holes are opened, which can easily lead to cracking and deformation of the support, thus affecting the overall service life of the support. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bracket for fixing the lock body of the ground lock to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A bracket for fixing the lock body of a floor lock includes a bracket, a fixing groove is provided on the surface of the bracket, an anti-slip layer is fixedly installed inside the fixing groove, a door frame floor lock is fixedly installed on one side of the anti-slip layer, and a support mechanism is provided on one side of the bracket;

[0009] The support mechanism includes two support plates fixedly installed inside the bracket. The surfaces of the two support plates and the bracket are provided with two first threaded holes. The surface of the door frame lock is provided with two second threaded holes. The diameters of the first threaded holes and the second threaded holes are the same. The surfaces of the bracket and the support plates are provided with fixing threaded holes, which are located on one side of the first threaded holes. The interior of the bracket is provided with multiple mounting grooves, and reinforcing strips are fixedly installed inside the multiple mounting grooves.

[0010] By adopting the above technical solution, the load-bearing capacity of the threaded hole is enhanced, thereby dispersing external pressure, preventing deformation and cracking of the area around the threaded hole due to pressure concentration, improving compressive strength, protecting the hole wall structure from damage by external impact, and extending the service life of the bracket.

[0011] As a further description of the above technical solution: the anti-slip layer is made of rubber, the reinforcing strip is made of high-strength alloy steel, a carbonitriding layer is fixedly provided on the surface of the bracket, a galvanized layer is fixedly provided on one side of the carbonitriding layer, and an elastic plastic layer is fixedly provided at the bottom of the bracket.

[0012] By adopting the above technical solution, friction is increased, preventing the ground lock from shifting or loosening on the bracket, ensuring normal operation. It also acts as a buffer, reducing collision noise, protecting the ground lock and bracket structure, enhancing the overall strength and load-bearing capacity of the bracket, improving surface hardness, and ensuring long-term stable operation of the ground lock.

[0013] As a further description of the above technical solution: two limiting grooves are opened on the surface of the bracket, and the two limiting grooves are opened on both sides of the fixing groove. A first magnetic strip is fixedly installed inside the limiting groove. A second magnetic strip is magnetically connected to one side of the first magnetic strip. One end of the second magnetic strip is connected to the surface of the door frame floor lock.

[0014] By adopting the above technical solution, it is possible to effectively ensure that the door frame floor lock is accurately installed in the predetermined position in the fixed groove, avoiding horizontal deviation or shaking, achieving precise positioning, and ensuring the normal locking and unlocking functions of the floor lock.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up a support mechanism, compared with the existing technology, the door frame floor lock is inserted into the inside of the fixing groove, and the surface of the door frame floor lock is made to fit the anti-slip layer. The door frame floor lock is initially positioned. Since the anti-slip layer is made of rubber material, the friction is increased, preventing the floor lock from shifting or loosening on the bracket, ensuring normal operation. The second threaded hole on the surface of the door frame floor lock is aligned with the first threaded hole. Then, the external bolt is rotated into the second threaded hole and the first threaded hole, and then fixed by the cooperation of the external nut. This ensures that the door frame floor lock will not loosen or shift from the bracket during use, enhancing the stability effect. Moreover, the support plate distributes the pressure more evenly to the support plate and bracket to ensure the normal operation of the door frame floor lock.

[0017] 2. By setting up a door frame floor lock, a first magnetic strip, a second magnetic strip, and a carbonitriding layer, compared with the existing technology, when the door frame floor lock moves downwards, it drives the second magnetic strip downwards until the second magnetic strip magnetically attracts the first magnetic strip. This causes the door frame floor lock to perform position calibration, ensuring that the door frame floor lock can be accurately positioned when installed on the bracket, avoiding horizontal deviation or shaking. This ensures the consistency of the door frame floor lock's position after each installation, strengthens the bracket's hardness and wear resistance, and slows down the corrosion rate of the bracket, ensuring the long-term stable operation of the door frame floor lock.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1-5 As shown, this embodiment provides a bracket for fixing the lock body of the floor lock, including a bracket 1. A fixing groove 2 is opened on the surface of the bracket 1. An anti-slip layer 3 is fixedly installed inside the fixing groove 2. A door frame floor lock 4 is fixedly installed on one side of the anti-slip layer 3. A support mechanism is provided on one side of the bracket 1.

[0027] The support mechanism includes two support plates 5 fixedly installed inside the bracket 1. The surfaces of the two support plates 5 and the bracket 1 are provided with two first threaded holes 6. The surface of the door frame lock 4 is provided with two second threaded holes 7. The diameters of the first threaded holes 6 and the second threaded holes 7 are the same. The surfaces of the bracket 1 and the support plates 5 are provided with fixing threaded holes 8. The fixing threaded holes 8 are located on one side of the first threaded holes 6. The interior of the bracket 1 is provided with multiple mounting grooves. Reinforcing strips 9 are fixedly installed inside the multiple mounting grooves.

[0028] As can be seen, in the above technical solution, the door frame floor lock 4 is inserted into the inside of the fixing groove 2, and the surface of the door frame floor lock 4 is made to adhere to the anti-slip layer 3. The door frame floor lock 4 is initially positioned. Since the anti-slip layer 3 is made of rubber, it enhances the fixing effect of the door frame floor lock 4 in the fixing groove 2. The second threaded hole 7 on the surface of the door frame floor lock 4 is aligned with the first threaded hole 6. Then, the external bolt is rotated into the inside of the second threaded hole 7 and the first threaded hole 6, and then fixed by the cooperation of the external nut. This ensures that the door frame floor lock 4 will not loosen or shift from the bracket 1 during use, thus enhancing the stability effect. Moreover, the support plate 5 distributes the pressure more evenly to the support plate 5 and the bracket 1 to ensure the normal operation of the door frame floor lock 4.

[0029] Usage Procedure: First, insert the door frame floor lock 4 into the fixing groove 2, ensuring the surface of the door frame floor lock 4 adheres to the anti-slip layer 3 for initial positioning. Since the anti-slip layer 3 is made of rubber, it enhances the fixation of the door frame floor lock 4 within the fixing groove 2. Align the second threaded hole 7 on the surface of the door frame floor lock 4 with the first threaded hole 6. Then, rotate the external bolt into the second threaded hole 7 and the first threaded hole 6, and secure it using the external nut. This ensures the door frame floor lock 4 will not loosen or shift from the bracket 1 during use. Next, rotate the external screw into the fixing threaded hole 8, thus fixing the bracket 1 to the designated position. Since a support plate 5 is fixedly installed at the bottom of the bracket 1, and the surface of the support plate 5 also has the first threaded hole 6 and the fixing threaded hole 8, when subjected to external force, it will be transmitted to the first threaded hole 6 through the external bolt. The first threaded hole 6 and the fixed threaded hole 8 are located in the area. The presence of the support plate 5 can distribute the pressure, which was originally concentrated in the local area around the first threaded hole 6 and the fixed threaded hole 8, more evenly to the support plate 5 and the bracket 1, avoiding excessive pressure concentration on the first threaded hole 6 and the fixed threaded hole 8. This prevents the part from deforming, cracking, or other damage due to excessive pressure, effectively improving the ability to withstand external forces. Moreover, the bracket 1 has multiple reinforcing strips 9 inside, which is equivalent to enhancing the compressive strength of the entire bracket 1. When the key is inserted and turned, the key drives the lock cylinder to rotate. The lock cylinder pushes the bolt into the lock body through the internal mechanical structure, so that the door can be opened or closed freely. When the door is closed, the bolt automatically extends under the action of the spring and inserts into the lock hole on the door frame to lock the door. This is the existing technology and will not be described in detail in this technical solution.

[0030] Example 2

[0031] like Figure 3-5 As shown, this embodiment provides a bracket for fixing the lock body of the floor lock. The anti-slip layer 3 is made of rubber, the reinforcing strip 9 is made of high-strength alloy steel, a carbonitriding layer 10 is fixedly provided on the surface of the bracket 1, a galvanized layer 11 is fixedly provided on one side of the carbonitriding layer 10, and an elastic plastic layer 12 is fixedly provided at the bottom of the bracket 1. It can be seen that in the above technical solution, two limiting grooves 13 are opened on the surface of the bracket 1. Both limiting grooves 13 are opened on both sides of the fixing groove 2. A first magnetic strip 14 is fixedly provided inside the limiting groove 13. A second magnetic strip 15 is magnetically connected to one side of the first magnetic strip 14. One end of the second magnetic strip 15 is connected to the surface of the door frame floor lock 4.

[0032] As can be seen, in the above technical solution, when the door frame floor lock 4 moves downward, it drives the second magnetic strip 15 to move downward until the second magnetic strip 15 magnetically attracts the first magnetic strip 14, thereby driving the door frame floor lock 4 to perform position calibration, so that the door frame floor lock 4 can be accurately positioned when installed on the bracket 1, avoiding positional deviations during installation, ensuring the consistency of the position of the door frame floor lock 4 after each installation, strengthening the hardness and wear resistance of the bracket 1, and slowing down the corrosion rate of the bracket 1, thereby improving the performance.

[0033] Usage: The external screw is rotated into the fixing threaded hole 8 to fix the bracket 1 in the designated position. When the door frame floor lock 4 is placed into the fixing groove 2, the door frame floor lock 4 moves downward, causing the second magnetic strip 15 to move downward until the second magnetic strip 15 magnetically attracts the first magnetic strip 14. This causes the door frame floor lock 4 to perform position calibration, ensuring that the door frame floor lock 4 is accurately positioned when installed on the bracket 1, avoiding positional deviations during installation and ensuring the consistency of the door frame floor lock 4's position after each installation. Furthermore, the surface of the bracket 1... A carbonitriding layer 10 is fixedly provided on the surface of the bracket 1, so that carbon atoms and nitrogen atoms can simultaneously penetrate into the surface of the bracket 1 to form a carbonitriding layer. This layer has the high hardness and certain wear resistance of the carburized layer, as well as the good anti-galling and minimal impact on the matrix structure of the nitrided layer. This can comprehensively improve the performance of the bracket 1. At the same time, a zinc-plated layer 11 is fixedly provided on one side of the carbonitriding layer 10. In the air, a dense zinc oxide protective film will form, which can effectively prevent oxygen, moisture and other substances in the air from contacting the metal matrix of the bracket, thereby slowing down the corrosion rate of the bracket 1 and ensuring the long-term stable operation of the door frame floor lock 4.

[0034] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
