Description

Technical Field

[0001] The present invention belongs to the technical field of door stoppers, and more specifically relates to a door stopper that can be used on both the pile surface and the smooth surface.

Background Art

[0002] In order to prevent people outside the door from entering the room by decrypting a recognition password or a mechanical key, some doors are equipped with a mechanical door chain structure. The mechanical door chain mechanism includes a socket provided on the wall and an insertion part provided on the door body. The insertion part is connected to the door body via a chain, and the safety is improved by inserting the insertion part into the socket. However, most doors are not equipped with the above mechanical door chain structure, and only a door stopper device with a simpler structure is used to prevent people outside the door from pushing open the door. A general door stopper device includes a door stopper body. The door stopper body has a contact plane that contacts the ground and a contact slope that intersects the contact plane and can firmly press the lower edge of the door. When the door opens towards the room, the lower edge of the door contacts the contact slope, and the door stopper body prevents further opening of the door by the frictional force between the ground and the contact plane. However, when the ground is relatively smooth and the force to open the door is large, the door may push the door stopper and slide together, rendering the door stopper device ineffective.

[0003] Therefore, the door stopper device with the publication number "CN220909415U" includes a rubber body. The bottom of the rubber body has an installation plane, and a plurality of adsorption members are fixedly installed on the installation plane. The plurality of adsorption members are distributed at intervals on the installation plane. The adsorption member has a downward adsorption surface. The rubber body has a contact inclined surface provided obliquely with respect to the installation plane. A wedge-shaped insertion end portion is formed at the boundary between the contact inclined surface and the installation plane, and the insertion end portion is used to contact between the lower edge of the door and the ground. When the above door stopper device is installed on the ground, the adsorption surface adsorbs to the ground. When the door is opened, the insertion end portion enters between the lower edge of the door and the ground. As the opening angle of the door increases, the lower edge of the door moves upward along the contact inclined surface, and the rubber body undergoes a certain elastic deformation to adhere closely between the lower edge of the door and the ground. During this period, a large adsorption force is formed between the plurality of adsorption members and the ground to prevent the rubber body from moving relative to the ground, thereby improving safety.

[0004] However, for the above door stopper device, the suction cup contacts the ground to deform the arc concave surface, thereby discharging the air between the adsorption surface and the ground. Due to the pressure difference between the atmospheric pressure and the cavity between the adsorption surface and the ground, the suction cup adsorbs to the ground, and it has a more stable adsorption effect compared to other adsorption members. However, in the using process, it can only be used on a smooth and flat ground, and the stopping effect on the door is not very good. Moreover, there is an obvious defect that it cannot adsorb and fix to carpets, blankets, etc. with a pile surface on the ground.

Embodiments for Carrying Out the Invention

[0014] The following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the drawings of the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0015] Referring to FIG. 1, the present invention provides the following technical solutions. The pile surface and smooth surface dual-purpose door stopper includes a rigid core 1 and an outer layer anti-slip body 4. The rigid core 1 has an inclined surface structure, and the rigid core 1 is injection molded by an injection molding die and integrally formed, and is integrally formed by injection molding a rigid material, which can increase the strength of the entire door stopper. A rubber-coated positioning ring 2 for positioning during injection molding is provided at one end of the concave surface of the end of the rigid core 1 on the ground. A circular soft magnet sheet 3 is fitted into the lower end surface of the rigid core 1, whereby the door stopper can be adsorbed on the surface of the door or the wall surface when it does not stop the door. And the soft magnet sheet 3 has a certain elastic bending degree and is not prone to damage and breakage. The inner wall of the groove locking part 5 has an arc-shaped angle, which is beneficial for locking and integrally attaching the carpet claw 7. And a core combination cavity for attaching and fixing the rigid core 1 is provided on the bottom surface of the outer layer anti-slip body 4, whereby the rigid core 1 can be wrapped by the outer layer anti-slip body 4 to stop the door body. The carpet claw 7 that comes into contact with the pile surface and the smooth surface to perform anti-slip is locked in the groove locking part 5. The surface of the door stopper having the carpet claw 7 contacts the surface of the carpet, which can well stop the door body and ensure the firm stability after the door body is stopped.

[0016] The outer anti-slip body 4 is fitted in combination with the outside of the rigid core 1 by using a core combination cavity, so as to have the effect of stopping and fixing the door body to the rigid core 1. At the central position of the inner bottom surface of the groove locking part 5, a positioning circular hole 8 is provided which penetrates and positions by combining with the rubber-coated positioning ring 2. After combining the rigid core 1, it plays a role in positioning, avoiding the phenomenon that the outer anti-slip body 4 falls off. The carpet claw 7 is locked inside the groove locking part 5 and positioned and combined with the rubber-coated positioning ring 2. A conical claw body 9 is uniformly provided on the surface of the carpet claw 7. Thereby, the door stopper generates a gripping force by using the conical claw body 9 and is positioned on the carpet of the pile surface, and the phenomenon of displacement will not occur.

[0017] A combined positioning concave surface 10 is provided at one end of the surface of the rigid core 1. The rubber-coated positioning ring 2 is provided at the central position of the surface of the combined positioning concave surface 10, realizing the close integration of the rigid core 1 and the outer anti-slip body 4. On one inclined surface of the outer anti-slip body 4, an anti-slip rib 6 is provided which makes the outer anti-slip body 4 contact with a smooth surface to stop and fix the door body. Thereby, the door stopper contacts with a smooth bottom surface by using the anti-slip rib 6 to generate frictional resistance, making the door stopper more stable and firm on a smooth ground. The anti-slip rib 6 is a strip-shaped protrusion structure and is uniformly provided on the surface of the outer anti-slip body 4. The cavity of the groove locking part 5 extends downward to one end inside the core combination cavity. The arc-shaped inner wall on one side of the combined positioning concave surface 10 is combined and locked with the outer side surface of the groove locking part 5.

[0018] Specifically, during use, when the front and back surfaces of the door stopper are in use, the outer layer anti-slip body 4 and the rigid core 1 are fitted together and integrally combined using the core combination cavity. The rubber-coated positioning ring 2 is passed through the positioning circular hole 8 and positioned and fixed inside the core combination cavity. The soft magnet sheet 3 is fitted onto one surface of the rigid core 1. The carpet claw 7 having the structure of the conical claw body 9 is locked and attached to the groove locking portion 5. Then, the surface on which the carpet claw 7 is attached is fixed downward to the ground of the pile surface. The gradient of the door stopper itself firmly presses the gap between the door and the ground to play a role in fixing the door. Conversely, when the other surface of the door stopper is turned downward, it firmly presses the gap between the door and the ground and contacts the smooth ground surface to play a role in fixing the door. And the soft magnet sheet 3 can play a role in storage and can be adsorbed on the surface of the door or the wall surface when the door stopper is not in use, further expanding the scope 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-described embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the above-described embodiments or equivalently replace some of their technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should all be included within the protection scope of the present invention.
