Description

Technical Field

[0001] The utility model relates to a door stopper, in particular to a detachable door stopper. Background Art

[0002] Currently, there are two types of door catches: split and integrated. Split door catches consist of a column and a base, one of which is fixed to the door and the other to the wall or glass. The column and base are magnetically fixed together by opening and closing the door. In the existing technology, the column or base is generally fixed to the wall or glass using adhesive or suction cups.

[0003] Although the suction cup is easy to fix, it is easy to stick and difficult to remove. Frequent disassembly and assembly will result in a higher damage rate of the door catch. Therefore, it is not convenient to adjust the installation position frequently and it is not convenient to reuse. Summary of the Invention

[0004] In order to address the shortcomings of the existing technology, the present invention provides a detachable door stopper, which uses a threaded connection and a pressure piece to install and fix the suction cup, making it easy to remove and install the door stopper on the installation surface, which is conducive to extending the service life of the door stopper. The technical solutions adopted by the present invention are:

[0005] A detachable door stopper, comprising

[0006] A column, one end of which is inwardly recessed to form a hidden groove, and a through hole is provided along the axis of the column and penetrates the column;

[0007] A pressing piece, hidden in the hidden groove;

[0008] A suction cup is located on one side of the column, a hard seat is protruding from the middle of the suction cup, and a threaded hole is provided on the hard seat;

[0009] A threaded column, passing through the through hole, one end of which can be threadedly connected to the threaded hole;

[0010] The ball head is connected to the other end of the threaded column and can be abutted against the other end of the column.

[0011] Furthermore, a step is provided at the bottom of the hidden groove, and the cover bottom of the pressing piece is clamped on the step.

[0012] Furthermore, the pressing piece is in the shape of a cover, and a guide hole is arranged on the end surface of the pressing piece coaxially with the pressing piece.

[0013] Furthermore, the pressing piece is cylindrical in shape.

[0014] The advantages of the utility model are as follows: after the suction cup is attached to the mounting surface, the threaded column penetrates the column and is threadedly connected to the threaded hole, and the pressing piece gradually presses the suction cup for a circle. As the thread is gradually screwed in, the part of the suction cup located inside the pressing piece is gradually pulled up to generate adsorption force, so that the suction cup is connected to the column and fixed to the mounting surface together; conversely, the suction cup can be removed by gradually releasing the suction cup by rotating the threaded column in the opposite direction, thus achieving the effect of simultaneous adsorption and assembly;

[0015] The pressure piece makes the suction cup not only subject to the pulling force towards the column under the action of the threaded connection, but also to the pressure of the pressure piece towards the suction cup. In addition, the hard seat is hidden inside the pressure piece along with the threaded connection, which makes the force on the suction cup more concentrated, and the suction cup has better stability, is not easy to shake, and is even not easy to be damaged.

[0016] The steps enable the pressing piece to quickly match the hidden groove of the door stopper body, making the positioning of the pressing piece faster and more convenient, ensuring the coaxiality between the pressing piece, suction cup and column, and making the suction cup more evenly stressed.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is 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 the present invention and are not intended to limit the present invention.

[0020] Please see the attached Figure 1 The utility model provides a detachable door stopper, including a column 100, one end of the column 100 is recessed inwardly and provided with a hidden groove 110, and a through hole 120 is provided along the axis of the column 100 and passes through the column 100; a pressing piece 200 is hidden in the hidden groove 110; a suction cup 300 is located on one side of the column 100, and a hard seat 310 is protruding in the middle of the suction cup 300, and a threaded hole 400 is provided on the hard seat 310; a threaded column 500 passes through the through hole 120, and one end of which can be threadedly connected to the threaded hole 400; a ball head 600 is connected to the other end of the threaded column 500 and can be abutted against the other end of the column 100.

[0021] In a specific embodiment, the top of the threaded column 500 is fixedly connected to the ball head 600, and the axis of the threaded column 500, the axis of the through hole 120, the axis of the pressure piece 200, the axis of the hard seat 310, and the axis of the suction cup 300 coincide; the outer diameter of the hard seat 310 is smaller than the inner diameter of the pressure piece 200, and the diameter of the suction cup 300 is larger than the diameter of the corresponding end face of the column 100. When in use, fit the suction cup 300 to the required installation surface and rotate the ball head 600 to screw the threaded column 500 into the threaded hole 400, so that the suction cup 300 gradually approaches the pressure piece 200. The suction cup is subjected to the tension of the threaded column 500 and the pressure of the pressure piece 200 at the same time, so that an adsorption force is generated in the middle of the suction cup 300 and it is firmly adsorbed on the installation surface, while preventing the suction cup 300 from shaking. When it is necessary to adjust the installation position of the door suction or remove the door suction, you only need to rotate the ball head 600 in the opposite direction to remove the adsorption force of the suction cup. The operation is convenient and quick and will not damage the suction cup. When the ball head 600 is against the other end face of the column 100, it means that the threaded column 500 has been screwed in to the maximum stroke, avoiding excessive pulling on the suction cup 300 and causing damage to the suction cup 300. In summary, the use of the pressure piece 200, the threaded hole 400 and the threaded column 500 can achieve the technical effect of quickly fixing the suction cup, maintaining a stable fixed state, and quickly disassembling and assembling. In particular, the pressure piece 200 is used to stably support the suction cup between the column 100 and the suction cup 300, and the coaxiality of the rotating structure is used to achieve uniform force on the suction cup 300.

[0022] Furthermore, the present application hides the pressure piece 200 in the hidden groove 110, which can shorten the overall length of the door suction and prevent the pressure piece 200 from being exposed to the outside and affecting the appearance or being bumped.

[0023] In some embodiments, the threaded column 500 is fixed to the ball head 600 by a nut or by welding.

[0024] In one embodiment, the pressing member 200 is made of hard plastic.

[0025] The bottom of the hidden groove 110 is provided with a step, and the bottom cover of the pressure piece 200 is snapped onto the step. The step allows the pressure piece 200 to quickly mate with the hidden groove 110 of the column 100, making positioning of the pressure piece 200 faster and more convenient, ensuring the coaxiality between the pressure piece 200, the suction cup 300, and the column 100, and more evenly applying force to the suction cup 300. In this embodiment, the pressure piece 200 and the column 100 can be pre-bonded or provided separately.

[0026] The pressing member 200 is in the shape of a cap, and a guide hole 210 is arranged coaxially with the end surface of the pressing member 200. The cap-shaped pressing member 200 maximizes the contact surface between the step and the pressing member 200, and the positioning of the pressing member 200 is also the most stable. Alternatively, the pressing member 200 is in the shape of a cylinder.

[0027] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to examples, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
