Technical Field

[0001] This utility model relates to the field of hardware accessories technology, specifically to a door closer that is easy to maintain. Background Technology

[0002] A doorstop, also known as a door catch or door stop, is a hardware accessory installed between a door and the floor or wall. It is primarily used to secure an open door, preventing it from closing or swinging freely under wind or other external forces, thus keeping the door open. In daily life, when people need to keep the door open for extended periods, such as when moving items or for ventilation, a doorstop can hold the door in place, preventing frequent closing and providing convenience.

[0003] However, existing door catches are usually fixed to the door body. The door catches usually include a reset structure. Due to their complex structure and scattered installation inside the door catches, the existing reset structure is time-consuming to maintain or replace, which in turn reduces the user experience.

[0004] Therefore, a new type of door catch is urgently needed. Utility Model Content

[0005] This invention proposes a door catcher that is easy to maintain, solving the problem of cumbersome maintenance caused by the scattered arrangement of the reset structure in existing door catchers.

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

[0008] A clip is inserted into the receiving cavity at one end and protrudes out of the receiving cavity at the other end. The clip is slidably disposed on the clip seat.

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

[0010] The card head avoids the card-attaching protrusion by means of the compression reset component.

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

[0012] Guide posts are disposed within the accommodating cavity;

[0013] A spring is sleeved on the outside of the guide post, with one end of the spring connected to the guide post and the other end connected to the clip head.

[0014] As a further technical solution, the guide post is provided with a clearance hole inside, and the insertion end of the clamp head is provided with a connecting post, which passes through the clearance hole.

[0015] As a further technical solution, the snap-fit ​​structure also includes a mounting plate and a mounting post, the mounting plate being disposed within the accommodating cavity, and the mounting post passing through both the mounting plate and the guide post.

[0016] As a further technical solution, the mounting end of the guide post is disc-shaped, the clearance hole is a stepped hole, one end of the spring abuts against the disc-shaped structure, and the other end abuts against the end face of the stepped hole.

[0017] As a further technical solution, the snap-fit ​​structure also includes a guide plate and a sliding post. The guide plate has a sliding hole, and the sliding post passes through the sliding hole and through the snap-fit ​​head.

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

[0040] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0041] like Figures 1 to 11 As shown, this embodiment proposes a door closer that is easy to maintain, including a base 1 and a snap-fit ​​structure. The base 1 is set on the ground, and the snap-fit ​​structure is set on the door body. The base 1 is provided with snap-fit ​​protrusions, and the snap-fit ​​structure includes:

[0042] The card holder is connected to the door body and has an internal cavity.

[0043] The card head 2 is inserted into the receiving cavity at one end and protrudes out of the receiving cavity at the other end. The card head 2 is slidably disposed on the card seat.

[0044] A compression reset assembly is disposed within the accommodating cavity, and the insertion end of the chuck 2 abuts against the compression reset assembly;

[0045] Among them, the card head 2 avoids the card-connecting protrusion by means of a compression reset component.

[0046] In this embodiment, the easy-to-maintain door catch includes a base 1 and a snap-fit ​​structure. The base 1 is placed on the ground, and the snap-fit ​​structure is placed on the door body. The base 1 has a snap-fit ​​protrusion. The snap-fit ​​structure includes a card seat, a card head 2, and a compression and reset assembly. The card seat is placed on the door body and has a receiving cavity. The compression and reset assembly is placed inside the receiving cavity. The card head 2 passes through the card seat, with its insertion end located inside the receiving cavity and in contact with the compression and reset assembly, and its exit end located outside the receiving cavity. As the door body moves, the snap-fit ​​structure also moves. During the movement, the card head 2 contacts the snap-fit ​​protrusion on the base 1. Under the action of the thrust, the card head 2 squeezes the compression and reset assembly, and then the card head 2 moves into the card seat until it completely avoids the snap-fit ​​protrusion, that is, it moves from one side of the snap-fit ​​protrusion to the other side. Since the snap-fit ​​structure is detachably installed on the door body, the snap-fit ​​structure can be quickly replaced. Furthermore, when the door is made of iron, the snap-fit ​​structure can be secured to the iron door using internal magnets. This quick-change snap-fit ​​structure facilitates door catch maintenance. Most importantly, the compression and reset assembly is fixed as a single unit within the mounting bracket, allowing for rapid replacement during maintenance, thus saving maintenance time and improving the user experience.

[0047] Furthermore, such as Figures 7-11 As shown, this embodiment proposes a compression reset component including:

[0048] Guide post 3 is installed inside the accommodating cavity;

[0049] Spring 4 is sleeved on the outside of guide post 3. One end of spring 4 is connected to guide post 3, and the other end is connected to clamp 2.

[0050] In this embodiment, the compression and 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 clamping head 2. Using the spring 4 to realize the reciprocating movement of the clamping head 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 movement direction of the clamping head 2. This ensures that the spring 4 deforms during compression and elongation, and also improves the stability of the clamping head 2 during movement.

[0051] Furthermore, such as Figure 11 As shown in the figure, this embodiment proposes that the guide post 3 is provided with an avoidance hole inside, and the insertion end of the clamp 2 is provided with a connecting post, which is inserted into the avoidance hole.

[0052] In this embodiment, the guide post 3 is provided with a clearance hole inside, and the axis of the clearance hole coincides with the axis of the guide post 3. A connecting post is provided on the insertion end of the clamping head. The connecting post can pass through the clearance hole and slide back and forth in the clearance hole. When the clamping head 2 encounters the clamping protrusion, the clamping head 2 will move in the vertical direction under the push of the clamping protrusion. However, the guide post 3 and the connecting post do not move in the vertical direction. Therefore, the connecting post can move in the clearance hole, which can play a guiding role and prevent the clamping head 2 from moving randomly.

[0053] Furthermore, such as Figures 7-11 As shown in the figure, the snap-fit ​​structure proposed in this embodiment also 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 clip 2 during the movement process, the clip structure also includes a mounting plate 5 and a mounting post 6. The mounting plate 5 is located in the accommodating cavity. Both the guide post 3 and the mounting plate 5 are provided with through holes. The mounting post 6 passes through both the mounting plate 5 and the guide post 3, so that the guide post 3 can be quickly installed and fixed in the accommodating cavity.

[0055] Furthermore, such as Figures 7-11 As shown in the figure, this embodiment proposes that the mounting end of the guide post 3 is in the shape of a disc, the clearance hole is a stepped hole, one end of the spring 4 abuts against the disc-shaped structure, and the other end abuts against the end face 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 post 3 is made into a disc shape, and the clearance hole is a stepped hole, so that the end of the spring 4 can abut against the end face of the disc-shaped structure and the end face inside the stepped hole respectively.

[0057] Furthermore, such as Figures 7-11 As shown in the figure, the snap-fit ​​structure proposed in this embodiment also includes a guide plate 7 and a sliding post 8. The guide plate 7 has a sliding hole, and the sliding post 8 passes through the sliding hole and through the snap-fit ​​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 post 8 are also provided in the accommodating cavity. The guide plate 7 has a sliding hole, which is in the shape of an elongated hole. The sliding post 8 passes through the sliding hole and is set through the sliding hole. The sliding post 8 and the chuck 2 move together in the vertical direction.

[0059] In a practical application, there are two guide plates 7 arranged symmetrically, each guide plate 7 is provided with a sliding hole, the clamp 2 is located between the two guide plates 7, and the sliding post 8 passes through the guide plate 7 (first) - clamp 2 - guide plate 7 (second) in sequence.

[0060] Furthermore, such as Figures 1 to 11 As shown, this embodiment proposes a card holder including:

[0061] Fixed base 9;

[0062] A fixing cover 10 is installed on a fixing seat 9, and a receiving cavity is formed between the fixing seat 9 and the fixing cover 10.

[0063] A fixing plate 11 is fixed on a fixing seat 9, and there is a gap between the fixing plate 11 and the fixing seat 9. A fixing hole is provided on the fixing plate 11.

[0064] The fixing plate 11 and the fixing cover 10 are respectively set on both sides of the fixing base 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 the guide plate 7 are both connected to the fixed base 9. The fixed cover 10 covers the fixed base 9, forming an accommodating cavity between the fixed base 9 and the fixed cover 10. The fixed plate 11 is secured to the fixed base 9, with a gap between them. A fixing hole is provided on the fixing plate 11, and the card holder is connected to the door body via this fixing hole. 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 by adhesive bonding, for example, by setting an adhesive layer or double-sided tape on the fixing plate 11. The card holder can also be fixed to the door by magnetic attraction. In this case, the door is made of iron, and a magnet is placed between the fixing plate 11 and the door. Alternatively, the fixing plate 11 itself is magnetic, or the material of the fixing plate 11 is a magnet.

[0067] Furthermore, such as Figures 1 to 11 As shown, in this embodiment, the back of the fixing base 9 is provided with a groove 12, and the side wall of the groove 12 is provided with a snap-fit ​​groove. The side of the fixing plate 11 passes through the snap-fit ​​groove to realize the detachable connection between the fixing plate 11 and the fixing base 9.

[0068] In this embodiment, a groove 12 is provided on the back of the fixing base 9, and a snap-fit ​​groove is provided on the side wall of the groove 12. The side of the fixing plate 11 passes through the snap-fit ​​groove, so that the fixing plate 11 and the fixing base 9 can be quickly replaced.

[0069] Furthermore, such as Figures 1 to 11 As shown, in this embodiment, the protruding end of the clip 2 is hemispherical. The surface of the clip protrusion that contacts the clip 2 is a smooth curved surface.

[0070] In this embodiment, to ensure the door opens or closes smoothly, it is necessary to appropriately reduce the friction between the latch head 2 and the latching protrusion on the base 1. Therefore, the protruding end of the latch head 2 is set to a hemispherical shape, which allows the latch head 2 to smoothly glide across the surface of the latching protrusion. Simultaneously, the surface where the latching protrusion contacts the latch head 2 can be set as a smooth curved surface.

[0071] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
