Description

[Technical Field]

[0001] The present invention belongs to the technical field of door stoppers, and specifically relates to a door stopper for both pile and smooth surfaces. [Background technology]

[0002] To prevent people outside the door from entering a room by cracking a password or mechanical key, some doors are equipped with a mechanical door chain mechanism. The mechanical door chain mechanism includes a striker mounted on the wall and an insertion part mounted on the door body. The insertion part is connected to the door body via a chain and is inserted into the striker, improving security. However, most doors do not have the mechanical door chain mechanism and rely solely on a simpler door stopper device to prevent people outside the door from pushing the door open. A typical door stopper device includes a door stopper body, which has a contact surface that contacts the ground and a contact slope that intersects with the contact surface and firmly presses against the lower edge of the door. When the door opens toward the room, the lower edge of the door contacts the contact slope, and the door stopper body prevents the door from opening further due to the friction between the ground and the contact surface. However, if the ground is relatively smooth and the door is opened with a large force, the door will push against the door stopper and slide together, rendering the door stopper device ineffective.

[0003] Therefore, the door stop device with publication number "CN220909415U" includes a rubber body, the bottom of which has a mounting plane, a plurality of suction members fixedly mounted on the mounting plane, the plurality of suction members being spaced apart on the mounting plane, the suction members having downward-facing suction surfaces, the rubber body having a contact slope obliquely arranged relative to the mounting plane, and a wedge-shaped insertion end formed at the boundary between the contact slope and the mounting plane, the insertion end being used to contact the lower edge of the door and the ground. When the door stop device is mounted on the ground, the suction surface adheres to the ground, and when the door is opened, the insertion end enters between the lower edge of the door and the ground, and as the opening angle of the door increases, the lower edge of the door moves from bottom to top along the contact slope, causing the rubber body to undergo a certain elastic deformation and to fit tightly between the lower edge of the door and the ground, during which a large suction force is generated between the plurality of suction members and the ground, preventing the rubber body from moving relative to the ground and improving safety.

[0004] However, with the above door stopper device, the suction cup comes into contact with the ground and deforms the concave arc, discharging the air between the suction surface and the ground, and the suction cup adheres to the ground due to the pressure difference between atmospheric pressure and the cavity between the suction surface and the ground. Although this has a more stable suction effect than other suction members, it can only be used on smooth, flat ground, its stopping effect on doors is not very good, and it cannot be adsorbed and fixed to pile-surfaced carpets, blankets, etc. on ground with pile surfaces, which are obvious defects.

[Brief explanation of the drawings]

[0013] [Figure 1] FIG. 1 is a schematic diagram of the exploded structure of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without requiring creative efforts all belong to the protection scope of the present invention.

[0015] Referring to FIG. 1, the present invention provides the following technical solution, which is a door stopper for pile surface and smooth surface, comprising a rigid core 1 and an outer layer anti-slip body 4: The rigid core 1 has a sloped structure, and is integrally formed by injection molding using an injection mold and is made of a rigid material, which can increase the strength of the entire door stopper. A rubber-coated positioning ring 2 is provided on one concave end of the end of the rigid core 1 for positioning during injection molding. A circular soft magnetic sheet 3 is fitted on the lower end surface of the rigid core 1, which allows the door stopper to adhere to the surface of the door or the wall when not stopping the door. The soft magnetic sheet 3 has a certain degree of elasticity and is less likely to break or fracture. The outer anti-slip body 4 has a recessed groove 5 at one end of one of its inclined surfaces, and the groove 5 and the outer anti-slip body 4 are injection-molded as a single unit. The inner wall of the groove 5 has an arc-shaped angle, which is advantageous for locking and integrally attaching the carpet nails 7. The bottom of the outer anti-slip body 4 is provided with a core assembly cavity for attaching and fixing the rigid core 1, so that the rigid core 1 is wrapped around the outer anti-slip body 4 to lock the door body. The groove 5 is fitted with the carpet nails 7 that come into contact with pile surfaces and smooth surfaces to provide anti-slip properties. The surface of the door stopper with the carpet nails 7 comes into contact with the surface of the blanket, which effectively locks the door body and ensures solid stability after the door body is locked.

[0016] The outer layer anti-slip body 4 is fitted onto the outside of the rigid core 1 using the core assembly cavity, thereby securing the door body to the rigid core 1. A positioning circular hole 8 is provided at the center of the inner bottom surface of the groove locking part 5, through which the rubber-coated positioning ring 2 is inserted when assembled, thereby serving to position the rigid core 1 after assembly and preventing the outer layer anti-slip body 4 from falling off. The carpet nail 7 is locked into the inside of the groove locking part 5 and positioned and assembled with the rubber-coated positioning ring 2. A conical nail body 9 having a uniform shape is provided on the surface of the carpet nail 7, so that the door stopper uses the conical nail body 9 to generate a gripping force and is positioned on the pile surface of the carpet, preventing slippage from occurring.

[0017] a mating positioning recess 10 is provided on one end of the surface of the rigid core 1, and the rubber-coated positioning ring 2 is located at the center of the surface of the mating positioning recess 10, thereby ensuring that the rigid core 1 and the outer anti-slip body 4 are tightly integrated together; an anti-slip rib 6 is provided on one inclined surface of the outer anti-slip body 4, which prevents the outer anti-slip body 4 from slipping when it comes into contact with a smooth surface to stop the door body; the door stopper uses the anti-slip rib 6 to come into contact with the smooth bottom surface and generate frictional resistance, making the door stopper more stable and firm on smooth ground; the anti-slip rib 6 is a strip-shaped protrusion structure that is evenly provided on the surface of the outer anti-slip body 4, the cavity of the groove locking part 5 extends downward to one end of the interior of the core mating cavity, and the arc-shaped inner wall on one side of the mating positioning recess 10 is mated and locked with the outer side of the groove locking part 5.

[0018] Specifically, when the front and back surfaces of the door stopper are in use, the outer anti-slip body 4 and the rigid core 1 are fitted together through the core assembly cavity, the rubber-coated positioning ring 2 is inserted through the positioning circular hole 8 to position and fix it inside the core assembly cavity, the soft magnetic sheet 3 is fitted onto one side of the rigid core 1, and the carpet nails 7 having the structure of conical nail bodies 9 are attached by engaging with the groove locking parts 5. Then, the side with the carpet nails 7 attached is fixed downwards on the pile surface of the ground, and the slope of the door stopper itself firmly presses against the gap between the door and the ground to fix the door. Conversely, the other side of the door stopper is turned downwards and presses against the gap between the door and the ground to come into contact with the smooth ground to fix the door. The soft magnetic sheet 3 can also function as a storage space, and can be attached to the surface of the door or a wall when the door stopper is not in use, further expanding the range of use.

[0019] Finally, the above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or equivalently replace some of the technical features thereof. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall all fall within the protection scope of the present invention.
