[0002] A door stopper, also known as a door catch or door stop, is a hardware accessory installed between a door and the floor or wall. It's primarily used to secure an open door, preventing it from closing or swinging due to wind or other external forces, and keeping it open. In daily life, when people need to keep a door open for extended periods of time, such as when moving items or for ventilation, door stoppers can help prevent frequent closings, providing convenience.

[0003] However, the existing door catch is usually connected to the door body in a fixed manner, and the door catch usually includes a reset structure. The existing reset structure is complex in structure and is installed in the door catch in a scattered manner, which results in a waste of time when maintaining or replacing the reset structure, thereby reducing the user experience.

[0004] Therefore, a new door stopper is urgently needed. Summary of the Invention

[0006] The technical solution of the present invention is as follows: A door stopper that is easy to maintain includes a base and a clamping structure, wherein the base is set on the ground, the clamping structure is set on the door body, and a clamping protrusion is set on the base. The clamping structure includes:

[0007] A card seat is connected to the door body, and has an accommodating cavity inside the card seat;

[0008] A clamping head is provided on the clamping seat, one end of the clamping head is inserted into the accommodating cavity, and the other end is extended out of the accommodating cavity, and the clamping head is slidably provided on the clamping seat;

[0009] A compression reset assembly is disposed in the accommodating cavity, and the insertion end of the clamp abuts against the compression reset assembly;

[0010] Wherein, the clamping head avoids the clamping protrusion with the help of the compression reset component.

[0011] As a further technical solution, the compression reset assembly includes:

[0015] As a further technical solution, the clamping structure further includes a mounting plate and a mounting post, the mounting plate is arranged in the accommodating cavity, and the mounting post passes through the mounting plate and the guide post at the same time.

[0016] As a further technical solution, the mounting end of the guide column is in a pancake shape, the avoidance hole is a stepped hole, one end of the spring abuts against the pancake structure, and the other end abuts against the end surface of the stepped hole.

[0017] As a further technical solution, the clamping structure further includes a guide plate and a sliding column. The guide plate is provided with a sliding hole. The sliding column is inserted into the sliding hole and passes through the clamping head.

[0018] As a further technical solution, the card holder includes:

[0019] Fixed seat;

[0020] A fixed cover, which is arranged on the fixed seat, and the accommodating cavity is formed between the fixed seat and the fixed cover;

[0021] A fixing plate is clamped on the fixing seat, with a gap between the fixing plate and the fixing seat, and a fixing hole is opened on the fixing plate;

The side of the fixing plate is inserted into the snap-in groove to achieve a detachable connection between the fixing plate and the fixing seat.

[0024] As a further technical solution, the protruding end of the clamp is hemispherical.

[0025] As a further technical solution, the surface where the clamping protrusion contacts the clamping head is a smooth curved surface.

[0026] The working principle and beneficial effects of the present invention are as follows: a door stopper that is easy to maintain includes a base and a clamping structure, wherein the base is arranged on the ground, the clamping structure is arranged on the door body, and a clamping protrusion is arranged on the base. The clamping structure includes a holder, a clamping head, and a compression reset assembly. The holder is arranged on the door body, and the holder has a receiving cavity. The compression reset assembly is arranged in the receiving cavity. The clamping head is passed through the holder, and the insertion end of the clamping head is located inside the receiving cavity and keeps contact with the compression reset assembly, while the exit end of the clamping head is located outside the receiving cavity. As the door body moves, the clamping structure also moves. During the movement, the clamping head will contact the clamping protrusion on the base. Under the action of the thrust, the clamping head will squeeze the compression reset assembly, and then the clamping head will move into the holder until it completely avoids the clamping protrusion, that is, moves from one side of the clamping protrusion to the other side of the clamping protrusion. Since the clamping structure is detachably arranged on the door body, the clamping structure can be quickly replaced. Furthermore, when the door is made of iron, the clip-on structure can be fixed to the iron door through internal magnets. This allows for quick replacement of the clip-on structure, facilitating maintenance of the door catch. Most importantly, the compression reset assembly is fixed integrally within the holder, allowing for quick replacement during maintenance, thus reducing door catch maintenance time and improving the user experience.

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0041] like Figures 1 to 11 As shown, this embodiment provides a door stopper that is easy to maintain, including a base 1 and a clamping structure. The base 1 is set on the ground, the clamping structure is set on the door body, and a clamping protrusion is set on the base 1. The clamping structure includes:

[0042] A card seat is connected to the door body and has an accommodating cavity inside the card seat;

[0043] The clamping head 2 is provided on the clamping seat, one end of the clamping head 2 is inserted into the accommodating cavity, and the other end is extended out of the accommodating cavity. The clamping head 2 is slidably provided on the clamping seat;

[0044] The compression reset assembly is arranged in the accommodating cavity, and the insertion end of the clamp head 2 abuts against the compression reset assembly;

[0045] The clamping head 2 avoids the clamping protrusion by means of a compression reset assembly.

[0046] In this embodiment, the door stopper that is easy to maintain includes a base 1 and a clamping structure. The base 1 is set on the ground, the clamping structure is set on the door body, and a clamping protrusion is set on the base 1. The clamping structure includes a base, a clamping head 2 and a compression reset assembly. The base is set on the door body, and the base has a accommodating cavity. The compression reset assembly is set in the accommodating cavity. The clamping head 2 is passed through the base, and the insertion end of the clamping head 2 is located inside the accommodating cavity and keeps contact with the compression reset assembly. The insertion end of the clamping head 2 is located outside the accommodating cavity. As the door body moves, the clamping structure will also move. During the movement, the clamping head 2 will contact the clamping protrusion on the base 1. Under the action of the thrust, the clamping head 2 will squeeze the compression reset assembly, and then the clamping head 2 will move into the base until it completely avoids the clamping protrusion, that is, moves from one side of the clamping protrusion to the other side of the clamping protrusion. Since the clamping structure is set on the door body in a detachable manner, the clamping structure can be quickly replaced. Furthermore, when the door is made of iron, the clip-on structure can be fixed to the iron door through internal magnets. This allows for quick replacement of the clip-on structure, facilitating maintenance of the door catch. Most importantly, the compression reset assembly is fixed integrally within the holder, allowing for quick replacement during maintenance, thus reducing door catch maintenance time and improving the user experience.

[0047] Further, if Figures 7 to 11 As shown, this embodiment proposes a compression reset component including:

[0048] A guide post 3 is provided in the accommodating cavity;

[0049] The spring 4 is sleeved on the outside of the guide column 3 , one end of the spring 4 is connected to the guide column 3 , and the other end is connected to the clamping head 2 .

[0050] In this embodiment, the compression reset assembly includes a guide post 3 and a spring 4. The guide post 3 is disposed within the accommodating cavity, and the spring 4 is sleeved on the outside of the guide post 3. One end of the spring 4 is connected to the guide post 3, and the other end is connected to the chuck 2. The use of the spring 4 to achieve reciprocating movement of the chuck 2 can reduce the complexity of the overall structure, thereby reducing the cost of the product, and further improving the overall ease of maintenance. In addition, the spring 4 is sleeved on the outside of the guide post 3, and the axis of the guide post 3 is consistent with the reciprocating direction of the chuck 2. This ensures that the spring 4 does not deform during compression and extension, and also improves the stability of the chuck 2 during movement.

[0051] Further, if Figure 11 As shown, this embodiment proposes that an avoidance hole is provided inside the guide column 3, and a connecting column is provided at the insertion end of the clamping head 2, and the connecting column is inserted into the avoidance hole.

[0052] In this embodiment, an avoidance hole is provided inside the guide column 3, and the axis of the avoidance hole coincides with the axis of the guide column 3. A connecting column is provided on the insertion end of the chuck, and the connecting column can be inserted into the avoidance hole and slide back and forth in the avoidance hole. When the chuck 2 encounters the clamping protrusion, the chuck 2 will move in the vertical direction under the push of the clamping protrusion, but the guide column 3 and the connecting column do not move in the vertical direction. Therefore, the connecting column can move in the avoidance hole, which can play a guiding role and prevent the chuck 2 from moving at will.

[0053] Further, if Figures 7 to 11 As shown, this embodiment proposes that the clamping structure further includes a mounting plate 5 and a mounting post 6 . The mounting plate 5 is disposed in the accommodating cavity, and the mounting post 6 passes through both the mounting plate 5 and the guide post 3 .

[0054] In this embodiment, in order to further improve the stability of the clamping head 2 during movement, the clamping structure also includes a mounting plate 5 and a mounting column 6. The mounting plate 5 is located in the accommodating cavity, and through holes are provided on the guide column 3 and the mounting plate 5. The mounting column 6 is also passed through the mounting plate 5 and the guide column 3. In this way, the guide column 3 can be quickly installed and fixed in the accommodating cavity.

[0055] Further, if Figures 7 to 11 As shown, this embodiment proposes that the installation end of the guide column 3 is in a pancake shape, the avoidance hole is a stepped hole, one end of the spring 4 abuts on the pancake structure, and the other end abuts on the end surface of the stepped hole.

[0056] In this embodiment, in order to further improve the stability of the spring 4 during deformation, the mounting end of the guide column 3 is made into a pancake shape, and the avoidance hole is selected as a stepped hole, so that the end of the spring 4 can respectively abut the end face of the pancake structure and the end face inside the stepped hole.

[0057] Further, if Figures 7 to 11 As shown, the present embodiment proposes that the clamping structure further includes a guide plate 7 and a slide post 8 . A slide hole is provided on the guide plate 7 . The slide post 8 is inserted into the slide hole and passes through the clamping head 2 .

[0058] In this embodiment, in order to further improve the stability of the chuck 2 during the vertical sliding process, a guide plate 7 and a sliding column 8 are also provided in the accommodating cavity. A sliding hole is provided on the guide plate 7. The sliding hole is in the shape of a long hole. The sliding column 8 is passed through the sliding hole, and the sliding column 8 is provided through the sliding hole. The sliding column 8 and the chuck 2 move together in the vertical direction.

[0059] In a practical application, there are two guide plates 7 and they are symmetrically arranged. A sliding hole is set on each guide plate 7. The clamping head 2 is located between the two guide plates 7. The sliding column 8 passes through the guide plate 7 (first) - clamping head 2 - guide plate 7 (second) in sequence.

[0060] Further, if Figures 1 to 11 As shown, this embodiment proposes that the card holder includes:

[0061] Fixed seat 9;

[0062] The fixed cover 10 is covered on the fixed base 9, and a receiving cavity is formed between the fixed base 9 and the fixed cover 10;

[0063] The fixing plate 11 is clamped on the fixing seat 9, with a gap between the fixing plate 11 and the fixing seat 9, and a fixing hole is opened on the fixing plate 11;

[0064] The fixing plate 11 and the fixing cover 10 are respectively arranged on both sides of the fixing seat 9 .

[0065] In this embodiment, to simplify the overall structure, the card holder includes a fixed base 9, a fixed cover 10, and a fixed plate 11. The mounting plate 5 and guide plate 7 are both connected to the fixed base 9. The fixed cover 10 covers the fixed base 9, forming a receiving cavity between the fixed base 9 and the fixed cover 10. The fixed plate 11 is fixed to the fixed base 9, with a gap between the fixed plate 11 and the fixed base 9. The fixed plate 11 has a fixing hole formed in the fixing plate 11, through which the card holder is connected to the door body. The fixing plate 11 and the fixed base 9 are detachably connected.

[0066] In a practical application, the card holder can be fixed to the door body by bonding, for example, an adhesive layer or double-sided tape is provided on the fixing plate 11. The card holder can also be fixed to the door body by magnetic attraction. At this time, the material of the door body contains iron, and then a magnet is placed between the fixing plate 11 and the door body, or the fixing plate 11 itself is magnetic, or the material of the fixing plate 11 is the magnet.

[0067] Further, if Figures 1 to 11 As shown, this embodiment proposes that a groove 12 is provided on the back of the fixing seat 9, and a snap-in groove is provided on the side wall of the groove 12. The side of the fixing plate 11 is inserted into the snap-in groove to achieve a detachable connection between the fixing plate 11 and the fixing seat 9.

[0068] In this embodiment, a groove 12 is provided on the back of the fixing seat 9, and a snap-in groove is provided on the side wall of the groove 12. The side of the fixing plate 11 is inserted into the snap-in groove, so that the fixing plate 11 and the fixing seat 9 can be quickly replaced.

[0069] Further, if Figures 1 to 11 As shown, this embodiment proposes that the protruding end of the clamping head 2 is hemispherical. The contact surface between the clamping protrusion and the clamping head 2 is a smooth curved surface.

[0070] In this embodiment, in order to smoothly open or close the door, it is necessary to appropriately reduce the friction between the clamping head 2 and the clamping protrusion on the base 1. Therefore, the protruding end of the clamping head 2 is configured as a hemispherical shape. This configuration allows the clamping head 2 to smoothly slide across the surface of the clamping protrusion. At the same time, the contact surface of the clamping protrusion with the clamping head 2 can also be configured as a smooth curved surface.

[0071] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
