[ detailed description ] of the utility model

In order to make the objects, technical solutions and advantageous technical effects of the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is intended to illustrate the utility model, and not to limit the utility model.

As shown in fig. 1 and 2, in the embodiment of the present utility model, a door 100 for preventing pinching is provided, which can maintain a door leaf at any angle, and can not be easily opened and closed, thereby improving safety.

The anti-pinch door 100 includes a door leaf 10, a rotatable door handle 20 provided on the door leaf 10, and an anti-pinch assembly.

A first groove 11 is formed on one side of the door leaf 10 close to the ground, namely, the opening of the first groove 11 is communicated with the outside towards the ground; the bottom wall of the first recess 11 is provided with a via 101. The anti-pinch component comprises a rope belt 31 and a counterweight 32 arranged in the first groove 11, wherein the rope belt 31 is made of non-telescopic materials, such as steel wires or hard plastics, etc., i.e. the rope belt 31 is not obviously stretched when being stretched; in addition, the shapes of the first groove 11 and the weight 32 are adapted, for example, the first groove 11 and the weight 32 may be rectangular or cylindrical at the same time, and the weight 32 may move up and down in the first groove 11.

One end of the rope belt 31 is connected with the counterweight 32, the other end passes through the through hole 101 and is connected with the door handle 20, specifically, the door handle 20 comprises a rotating shaft 21 installed in the door leaf 10 and a handle part 22 capable of rotating around the rotating shaft 21, and one end of the rope belt 31 is wound on the handle part 22; when the handle portion 22 rotates around the rotating shaft 21, the rope belt 31 is driven to wind, that is, the rope belt 31 is arranged between the weight piece 32 and the handle portion 22, and meanwhile, the rope belt 31 is always in a straightening stress state, that is, the rotation of the door handle 20 drives the rope belt 31 to pull the weight piece 32 away from or close to the ground; when the door handle 20 is in the initial state, the rope 31 is in a relaxed state, the weight 32 is pressed on the ground by self gravity, and the friction force is high, so that the door leaf 10 cannot be easily moved; when the user turns the door handle 20, the string 31 pulls the weight 32 upward, so that the weight 32 is separated from the ground, and friction between the weight 32 and the ground disappears, thereby facilitating the opening and closing of the door 10.

In one embodiment, as shown in fig. 2, a bottom wall of the first groove 11 is provided with a second groove 12 communicated with the first groove 11, and a spring 13 is arranged in the second groove 12; one end of the spring 13 is abutted against the bottom wall of the second groove 12, the other end is connected with the weight 32 and presses the weight 32 towards the ground, specifically, the second groove 12 is cylindrical and coaxially arranged with the first groove 11, at this time, the through hole 101 originally arranged on the bottom wall of the first groove 11 continues to extend and open on the bottom wall of the second groove 12, that is, the rope belt 31 passes through the through hole 101 from the door handle 20 and is connected with the weight 32 in the first groove 11 again. The spring 13 is compressed in the second groove 12, and two ends respectively abut against the bottom wall of the second groove 12 and one end, far away from the ground, of the counterweight 32, so that an elastic force F towards the ground is applied to the counterweight 32, and the stability of the door leaf 10 in the initial state is further enhanced according to a friction force formula friction force f=μ (mg+f), wherein μ is a friction coefficient, and at this time, the friction force between the door leaf 10 and the ground is larger.

Alternatively, in one embodiment, the side of the weight 32 close to the ground is provided with a friction pad 33, and the friction pad 33 may be a blanket or silica gel with a larger friction coefficient μ, so as to further enhance the friction between the weight 32 and the ground.

Optionally, in one embodiment, a buffer member 34 is disposed at an end of the weight member 32 near the bottom wall of the first recess 11; the area of the buffer 34 is larger than the cross-sectional area of the second recess 12; when the rope belt 31 drives the weight piece 32 to move far away from the ground, the buffer piece 34 can buffer the collision between the weight piece 32 and the bottom wall of the first groove 11, so as to avoid the damage to the door leaf 10 caused by the large sound and long-term collision of the weight piece 32, wherein the buffer piece 34 can be silica gel with certain elasticity, and of course, can also be composed of a spring piece.

Further, the soft cushion layer 111 is attached to the side wall of the first groove 11, and the soft cushion layer 111 is made of the same material as the buffer member 34, so as to avoid the excessive stress caused by the lateral movement of the weight member 32 to the side wall impact of the first groove 11, thereby causing larger sound or damaging the door leaf 10.

Optionally, the cross-sectional area of the end of the first groove 11 near the ground is continuously reduced along the direction near the ground, that is, the side walls of the portion of the first groove 11 near the ground are continuously retracted and close to each other, but the opening of the counterweight 32 penetrating through the first groove 11 is not affected to collide with the ground, so that the counterweight 32 accurately penetrates through the opening of the first groove 11, and the counterweight 32 does not laterally move relative to the first groove 11, so that the door leaf 10 is rocked.

In summary, according to the present utility model, the first groove 11 is formed in the door leaf 10 and the weight member 32 is disposed in the first groove 11, the friction between the door leaf 10 and the ground is increased by the weight member 32, so that the door leaf 10 cannot be easily closed.

The present utility model is not limited to the details and embodiments described herein, and thus additional advantages and modifications may readily be made by those skilled in the art, without departing from the spirit and scope of the general concepts defined in the claims and the equivalents thereof, and the utility model is not limited to the specific details, representative apparatus and illustrative examples shown and described herein.
