Description

Technical Field

[0001] This utility model relates to a door catch, and more particularly to a detachable door catch. Background Technology

[0002] Door catches come in two types: split and integrated. Split door catches consist of two parts: a column and a base. One column is fixed to the door, and the other is fixed to the wall or glass. The column and base are magnetically attached by opening and closing the door. In existing technology, the column or base is usually fixed to the wall or glass by adhesive or suction cup.

[0003] Although the suction cup fixing method is simple, it is easy to stick but not easy to remove. Frequent disassembly and assembly results in a high breakage rate for the door stopper. Therefore, the door stopper is not convenient to frequently adjust the installation position or reuse. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a detachable door catch that uses a threaded connection and a clamping mechanism to allow the suction cup to deflect or eliminate deflection, facilitating the installation and removal of the door catch and extending its service life. The technical solution adopted by this utility model is as follows:

[0005] A detachable door catch includes a door catch body, a pressing component, a suction cup, and a threaded connection.

[0006] The end face of the door catch body is recessed inward and a hidden groove is provided, and the pressing member is hidden in the hidden groove;

[0007] A rigid base is provided on the end face of the suction cup, coaxial with the suction cup;

[0008] The threaded connection portion connects the door catch body to the rigid base, allowing the door catch body and the rigid base to be connected or separated.

[0009] When the door catcher body is connected to the rigid base, one end of the rigid base enters the hidden groove, the pressure member abuts against the suction cup, and the suction cup undergoes elastic deformation.

[0010] Furthermore, a guide hole is arranged coaxially with the pressure member on the end face of the pressure member, and the threaded connection part includes a threaded hole and a threaded post. The threaded post can pass through the guide hole. When the threaded post is screwed into the threaded hole, the door catch body is connected to the rigid seat.

[0011] The threaded hole is located at the bottom of the hidden groove, and the threaded post is located on the end face of the rigid seat.

[0012] Alternatively, the threaded hole is located on the end face of the rigid seat, and the threaded post is located at the bottom of the hidden groove.

[0013] Furthermore, the bottom of the hidden groove is provided with a step, and the bottom cover of the pressing member is engaged with the step.

[0014] Furthermore, the shape of the pressure member is cap-shaped.

[0015] Furthermore, the shape of the pressure member is cylindrical.

[0016] Furthermore, the door catch body is a column, a base, or an integrated door catch.

[0017] The advantages of this utility model are as follows: After the suction cup is attached to the mounting surface through the hidden groove, pressure member, and threaded connection, rotating the door suction body causes the suction cup to gradually approach the pressure member under the action of the threaded connection. The pressure member gradually presses down on the suction cup. As the thread is gradually screwed in, the part of the suction cup located inside the pressure member is gradually lifted to generate an adsorption force, so that the suction cup and the door suction body are fixed together on the mounting surface. Conversely, rotating the door suction body in the opposite direction gradually releases the suction cup, which can then be removed.

[0018] The pressure member causes the suction cup to be subjected to not only the pulling force towards the door suction body, but also the pressure of the pressure member towards the suction cup under the action of the threaded connection. In addition, the hard seat is screwed into the pressure member and hidden inside the pressure member, which makes the force on the suction cup more concentrated, the suction cup more stable, less prone to shaking, and even less prone to damage.

[0019] The step design allows the pressure component to quickly match the hidden groove of the door catch body, making the pressure component positioning faster and more convenient. It also ensures the coaxiality between the pressure component, the suction cup, and the door catch body, resulting in more even force distribution on the suction cup. Attached Figure Description

[0023] In the diagram: 100-door catch body, 110-hidden groove, 120-step, 200-pressing part, 210-guide hole, 300-suction cup, 310-hard seat, 400-threaded hole, 500-threaded post. Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This utility model provides a detachable door catcher, including a door catcher body 100, a pressing member 200, a suction cup 300, and a threaded connection part; the end face of the door catcher body 100 is recessed inward and a hidden groove 110 is provided, and the pressing member 200 is hidden in the hidden groove 110; a rigid seat 310 is provided on the end face of the suction cup 300 and coaxially with the suction cup 300; the threaded connection part threadedly connects the door catcher body 100 and the rigid seat 310, so that the door catcher body 100 and the rigid seat 310 can be connected or separated; when the door catcher body 100 is connected to the rigid seat 310, one end of the rigid seat 310 enters the hidden groove 110, the pressing member 200 abuts against the suction cup 300, and the suction cup 300 undergoes elastic deformation. This application firstly uses a threaded connection to achieve a detachable connection between the suction cup 300 and the door catch body 100. At the same time, the tension generated on the suction cup during the threaded connection forces the suction cup to deflect and undergo elastic deformation, thus achieving simultaneous door catch assembly and adsorption fixation. When disassembling the door catch, simply rotate the thread in the opposite direction, the deflection disappears, the suction cup returns to its deformation, and the door catch assembly and disassembly are achieved simultaneously. The pressure member 200 increases the force on the suction cup 300. The two axial ends of the pressure member 200 abut against the door catch body 100 and the suction cup 300 respectively, making the force on the suction cup 300 more stable and concentrated, which serves to prevent the suction cup 300 from shaking and reduce damage to the suction cup 300.

[0026] In some embodiments, the door catch body 100 is a column, a base, or an integrated door catch; for example, when the door catch body 100 is a column, the suction cup 300 is connected to one end of the column, and a metal ball is installed at the other end of the column; as another example, when the door catch body 100 is a base, the suction cup 300 is connected to one end of the base, and a magnet is installed at the other end of the base; and as yet another example, when the door catch body 100 is an integrated door catch, the suction cup 300 is installed at one or both ends of the integrated door catch.

[0027] It is understandable that the structure of the suction cup 300 and the door suction body 100 have been disclosed in the existing technology, and will not be described in detail here.

[0028] In one embodiment, please refer to the appendix. Figure 1 and attached Figure 2 The end face of the pressure member 200 is provided with a guide hole 210 coaxially arranged with the pressure member 200. The threaded connection part includes a threaded hole 400 and a threaded post 500. The threaded hole 400 is located at the bottom of the hidden groove 110, and the threaded post 500 is located on the end face of the rigid seat 310. The threaded post 500 can penetrate the guide hole 210. When the threaded post 500 is screwed into the threaded hole 400, the door catch body 100 is connected to the rigid seat 310.

[0029] In this embodiment, when assembling the door catch, the threaded hole 400 on the door catch body 100 is aligned with the threaded post 500 on the suction cup 300 and the door catch body 100 is rotated. The threaded post 500 gradually enters the threaded hole 400, and at the same time, the suction cup 300 moves closer to the door catch body 100. After the pressure member 200 abuts against the surface of the suction cup 300, the suction cup 300 is gradually pulled up and deflected, so that the suction cup 300 is adsorbed and fixed on the required mounting surface.

[0030] In another embodiment, please refer to the appendix. Figure 3 The threaded connection includes a threaded hole 400 and a threaded post 500. The threaded hole 400 is disposed on the end face of the rigid seat 310, and the threaded post 500 is disposed at the bottom of the hidden groove 110. The threaded post 500 can penetrate the guide hole 210. When the threaded post 500 is screwed into the threaded hole 400, the door catch body 100 is connected to the rigid seat 310.

[0031] In this embodiment, when assembling the door catch, the threaded post 500 on the door catch body 100 is aligned with the threaded hole 400 on the suction cup 300 and the door catch body 100 is rotated. The threaded post 500 gradually enters the threaded hole 400, while the suction cup 300 moves closer to the door catch body 100. After the pressure member 200 abuts against the surface of the suction cup 300, the suction cup 300 is gradually pulled up and deflected, so that the suction cup 300 is adsorbed and fixed on the required mounting surface.

[0032] In this application, as attached Figure 1 and attached Figure 2 As shown, the bottom of the hidden groove 110 is provided with a step 120, and the bottom cover of the pressing member 200 is engaged with the step 120. The step allows the pressing member to quickly match the hidden groove of the door catch body, making the pressing member positioning faster and more convenient, ensuring the coaxiality between the pressing member, the suction cup, and the door catch body, and making the suction cup more evenly stressed. In this embodiment, the pressing member 200 and the door catch body 100 can be pre-bonded and fixed, or they can be set separately.

[0033] In one specific embodiment of this application, the pressure member 200 is cap-shaped. The cap-shaped pressure member 200 has the largest contact surface with the step 120, and the positioning of the pressure member 200 is also the most stable.

[0034] In another specific embodiment of this application, the pressure member 200 is cylindrical in shape.

[0035] It should be noted that the material of the clamping part 200 must be a rigid plastic or metal part, and cannot be a soft material such as a rubber. Regardless of whether the clamping part 200 is a cap or a cylinder, the inner diameter of the clamping part 200 must be larger than the diameter of the rigid base 310 to ensure that the rigid base 310 is submerged inside the clamping part 200 when the suction cup 300 is installed.

[0036] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
