Description

Technical Field

[0001] The utility model relates to a door stopper. Background Art

[0002] The current prior art, Chinese patent 202121960536.X, is a silent suction seat structure for door collision, which belongs to the field of hardware accessories technology. It solves the technical problem of poor service life of existing door collision structures. The silent suction seat structure of this door collision includes a seat body and a columnar collision suction head, and the collision suction head always has a tendency to move outward relative to the seat body along the axial direction of the collision suction head. The outer end face of the collision suction head is provided with an elastic buffer part, and the outer end of the elastic buffer part has an elastic support ring, and the axis of the elastic support ring is parallel to the axis of the collision suction head. The problem is that the length of the magnetic collision suction head extending out of the seat body cannot be adjusted to adapt to the gap between different doors and the main body.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a cross-sectional view of the utility model.

[0015] Figure 2 It is a cross-sectional view of a second embodiment of the present utility model. DETAILED DESCRIPTION

[0016] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] Example 1

[0019] like Figure 1 As shown, a door stopper is characterized in that it comprises a housing 1 with a front opening, a buffer member 2 and a screw 3,

[0020] A support column seat 11 is provided in the housing 1, and a screw hole is provided on the support column seat 11;

[0021] The buffer 2 includes a screwdriver hole 21 and a head hole 22 for fixing, and the screwdriver hole 21 and the head hole 22 are connected; the screw 3 includes a head 31 and a screw rod 32, and the head 31 is provided with a hexagonal countersunk hole, a cross screwdriver slot or a flat screwdriver slot.

[0022] The head 31 of the screw 3 is fixed to the head hole 22, the buffer 2 is loosely matched with the housing 1, the buffer 2 extends out of the housing 1, and the screw rod 32 of the screw 3 is screwed into the screw hole; the buffer 2 may be slidably matched with the inner cavity of the housing 1. The hexagonal countersunk hole, the cross screwdriver slot or the flat screwdriver slot is opposite to the screwdriver hole 21. The length of the buffer 2 extending out of the housing 1 can be adjusted by turning the screw 3.

[0023] As a further improvement of the present invention, the front end of the buffer 2 is a spherical curved surface; the buffer 2 is made of TPE or silicone material, has elasticity and plays a role in buffering and reducing noise.

[0024] The head 31 of the screw 3 is pre-buried in the head hole 22; alternatively, the head 31 can be directly embedded in the head hole 22 by utilizing the elasticity of the buffer.

[0025] As a further improvement of the present invention: a flange 12 is provided on the front opening end of the shell 1, and a buckle 13 is provided on the outer circumferential surface.

[0026] Example 2

[0027] like Figure 2 As shown, based on Example 1: it also includes a magnet ring 4, which is sleeved on the support column seat 11 and fixed to the shell 1, and there is a gap between the front end of the magnet ring 4 and the buffer member 2.

[0028] Or it can be detachable when fitted with a buffer;

[0029] When this embodiment is in use, it is arranged in the door frame or the door body, the front end of the shell is flush with the surface of the door frame or the door body, and another magnet component is arranged in the door body or the door frame; the magnet ring of this embodiment is magnetically attracted to the magnet component to prevent the door body from opening automatically, and can also adjust the gap between the door body and the door frame.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
