Abstract
Description
Technical Field
[0001] This utility model relates to the field of door catch technology, and in particular to a door catch with adjustable angle and suction force. Background Technology
[0002] A door catcher is a device used to secure an open door. It consists of two parts: a suction head and a suction base, and can be installed in both wall-mounted and floor-mounted versions. It uses magnetic force or a mechanical structure to prevent the door from closing automatically due to wind or impact. However, existing wall-mounted door catchers suffer from several drawbacks. Because the distance between the door and the wall varies depending on the installation environment, the door's opening angle also differs. This leads to inaccurate adhesion between the suction head and the suction base. Furthermore, the inability to adjust the angle of the suction head reduces suction force, causing the door to wobble. Additionally, existing door catchers generally use a ball-shaped design, which has a small contact area. Over time, this can cause wear and tear on the ball surface due to overload at the contact point, resulting in "adhesion slippage" and ultimately, door closure failure. Utility Model Content
[0003] This invention provides a door catcher with adjustable angle and suction force, which can effectively solve the above problems.
[0004] This utility model is implemented as follows: This utility model provides a door catcher with adjustable angle and suction force, comprising: a suction head and a suction base; The suction head includes a suction head body and a suction head rotating part, the suction head body and the suction head rotating part being rotatably connected. The suction head body is provided with a first adapter part, and the suction head rotating part is provided with a second adapter part. The first adapter part has a plurality of first meshing teeth formed around the rotation center on the side near the suction head rotating part, and the second adapter part has a plurality of second meshing teeth adapted to the first meshing teeth on the side near the suction head body. The suction head rotating part can rotate relative to the suction head body through the engagement of the first meshing teeth and the second meshing teeth, and can be positioned at a selected angle by the mutual locking of the first meshing teeth and the second meshing teeth, thereby realizing multi-level adjustment of the suction head angle.
[0005] As a further improvement, the suction head body is also provided with a mounting base, a first connecting part is provided between the first adapter and the mounting base, and a fixing part is provided on the side of the mounting base away from the first connecting part. The mounting base is fixed to the wall or door by the fixing part.
[0006] As a further improvement, the suction head rotating part is also provided with a second connecting part, and a slot is provided on one side wall of the second connecting part near the suction base, the slot being used to connect the magnet box.
[0007] As a further improvement, the second connecting part is provided with slots on both side walls near the magnet box.
[0008] As a further improvement, the magnet box has several slots, a handle is formed on the side of the magnet box near the slots, and protrusions are provided on the outer wall of the magnet box. The slots are used to install magnets.
[0009] As a further improvement, the second connecting part is provided with a rubber sleeve at the end near the suction base.
[0010] The beneficial effects of this utility model are: This invention utilizes a first and second meshing tooth mechanism between the suction head body and the suction head rotating part to achieve multi-position adjustment of the suction head angle. This ensures precise alignment and effective suction even when there are installation deviations in the door or slight displacement of the wall, eliminating door wobbling caused by misalignment and significantly improving product adaptability and installation tolerance. The interlocking positioning method using meshing teeth results in a simple and stable structure that provides reliable locking force after the selected angle is reached. Bolts further secure the suction head angle, preventing angle deviation due to vibration or external forces during use, ensuring long-term stability and reliability. Furthermore, the increased contact area of the meshing teeth effectively disperses the force of door impacts, reducing localized wear and extending product lifespan. The inclusion of a magnet box enhances the ease of magnet installation and replacement, and the number of magnets inside the box can be adjusted to change the suction force, allowing the door catcher to adapt to a wider variety of door styles.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0019] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0020] Reference Figure 1-5 As shown, a door catcher with adjustable angle and suction power includes: a suction head and a suction base 6; The suction head includes a suction head body 1 and a suction head rotating part 2. The suction head body 1 and the suction head rotating part 2 are rotatably connected. The suction head body 1 is provided with a first connecting part 11, and the suction head rotating part 2 is provided with a second connecting part 21. The first connecting part 11 has a plurality of first meshing teeth formed around the rotation center on the side near the suction head rotating part 2, and the second connecting part 21 has a plurality of second meshing teeth adapted to the first meshing teeth on the side near the suction head body 1. The suction head rotating part 2 can rotate relative to the suction head body 1 through the meshing of the first meshing teeth and the second meshing teeth, and can be positioned at a selected angle by the mutual locking of the first meshing teeth and the second meshing teeth, thereby realizing multi-level adjustment of the suction head angle. By setting a first meshing tooth and a second meshing tooth between the suction head body 1 and the suction head rotating part 2, multi-position adjustment of the suction head angle is achieved. This ensures that even if there are deviations in the door installation or slight displacement of the wall, the suction head angle can be adjusted to ensure that the suction head and the suction base 6 are always accurately aligned and effectively adsorb, eliminating the door shaking problem caused by misalignment and greatly improving the product's adaptability and installation error tolerance. Furthermore, the suction head consists of a suction head body 1 and a suction head rotating part 2. The suction head body 1 and the suction head rotating part 2 are rotatably connected. The suction head body 1 is provided with a first adapter part 11, and the suction head rotating part 2 is provided with a second adapter part 21 corresponding to the first adapter part 11. On the side of the first adapter part 11 near the center of rotation of the suction head rotating part 2, a plurality of evenly distributed first meshing teeth are formed. Correspondingly, on the side of the second adapter part 21 near the suction head body 1, second meshing teeth that are adapted to the first meshing teeth are formed. During assembly, the first meshing teeth and the second meshing teeth mesh with each other, and the suction head rotating part 2 rotates relative to the suction head body 1 through the locking between the teeth. It can be reliably positioned at multiple preset angle positions, thereby completing the adjustment of the suction head angle. The angle is fixed by bolt connection to prevent loosening and changes in angle.
[0021] The suction head body 1 is also provided with a mounting base 13. A first connecting part 12 extends between the first adapter part 11 and the mounting base 13. The mounting base 13 is provided with a fixing part on the side away from the first connecting part 12. The mounting base 13 is securely installed on the wall or door through the fixing part. The fixing part can be a bolt or adhesive, which is convenient for installation or removal on the wall or door. Furthermore, a scale line can be provided on the upper surface of the first connecting part 12 and near the first adapter part 11 to indicate the rotation angle of the suction head rotating part 2, which is conducive to quick adjustment of the door suction angle.
[0022] Furthermore, the suction head rotating part 2 is also provided with a second connecting part 22, which is fixedly connected to the second adapter part 21. A slot 221 is provided on one side wall of the second connecting part 22 near the suction base 6. An independent magnet box 3 can be inserted through this slot 221 and connected to the second connecting part 22 by being wrapped with an outer rubber sleeve 5. On the two side walls of the second connecting part 22 near the magnet box 3, there are also symmetrical slots 222, which are used to engage the rubber sleeve 5 to stably connect the rubber sleeve 5 to the second connecting part 22. A handle 32 is formed on the side of the magnet box 3 near the groove 31. The magnet box 3 can be pulled out of the groove 221 by the handle 32. A protrusion 33 is provided on the outer wall of the magnet box 3. The protrusion 33 is used to ensure that the magnet box 3 can be correctly inserted into the groove 221. Therefore, a connecting groove that matches the protrusion 33 is formed in the groove 221. In addition, multiple positioning blocks can be set on the outer wall of the magnet box 3, and corresponding positioning grooves can be set in the slot 221. When the magnet box 3 is inserted into the slot 221, a noticeable jamming sensation will occur when the positioning block contacts the positioning groove, thereby further improving the stability of the connection between the magnet box 3 and the second connecting part 22 and preventing it from loosening.
[0023] Furthermore, the magnet box 3 has at least one recess 31 inside for embedding magnets 4. By adjusting the number of magnets 4 inserted into the magnet box 3 and arranging them in the correct order, the strength of the suction head can be better adjusted to adapt to doors of different materials or weights, preventing damage to the door surface due to excessive suction. The magnet box 3 has an outwardly protruding handle 32 on the side near the opening of the recess 31, making it easy for the user to apply force to install or remove the magnet box 3. At the end of the second connecting part 22 near the suction base 6, a rubber sleeve 5 is also provided. The rubber sleeve 5 is usually made of elastic materials such as rubber or silicone, which serves to buffer and reduce noise when the suction head and suction base 6 collide, improving the user experience. Correspondingly, the suction base 6, as the part that attracts the suction head, preferably has an internal body made of soft magnetic material to provide optimal magnetic attraction. In addition, to achieve buffering and noise reduction during suction, a buffer sleeve can be wrapped around the outside of the suction holder 6. The buffer sleeve is preferably made of materials with good elasticity and wear resistance, such as rubber, silicone, or thermoplastic elastomer. The buffer sleeve can completely cover the exposed surface of the suction holder body, or it can mainly cover the front and edge areas where it may collide with the suction head or the rubber sleeve 5. The suction holder 6 is provided with a connecting part 7 on the side away from the suction head. The suction holder 6 is securely installed on the wall or door through the connecting part 7. The connecting part 7 can be a bolt or adhesive, which facilitates installation or removal from the wall or door.
[0024] Furthermore, the working principle of this utility model is as follows: During installation, first determine the optimal suction angle required by the suction head based on the actual position of the door after it is opened and the installation position of the suction base 6. Then, hold the rotating part 2 of the suction head and rotate it relative to the main body 1 of the suction head, which is already fixed to the door or wall. During this process, the first and second meshing teeth will slide relative to each other. When the rotation reaches a certain position, so that the magnet box 3 at the front end of the suction head rotating part 2 can be perfectly aligned with the suction base 6, stop rotating. At this time, under the mutual locking action of the meshing teeth, the suction head rotating part 2 is initially positioned at this angle, and then the angle is fixed and locked by bolts. Finally, install the suction base 6 in the corresponding position. When the door is opened, the suction base 6 will be tightly attracted to the magnet box 3 under the action of magnetic force, and the rubber sleeve 5 and the buffer sleeve provide cushioning, thereby keeping the door stably in the open state.
[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
