Problems solved by technology

[0004] The above-mentioned door blocking device can limit the opening stroke of the door body and adsorb and position the door body through the magnet, but the brittle magnet will easily be damaged after the door body collides with the suction seat for a long time, which will lead to the decline of the adsorption effect, and it is difficult to ensure the stability of the door body. The size of the door itself is fixed. In order to ensure the matching effect, the accuracy of the installation position is high, and the installation is inconvenient.

Embodiment 1

[0052] like Figure 1-6 As shown, the adjustable door stopper assembly includes a cylinder body 1 with one end open. The cylinder body 1 is provided with a limit pin 2 that can reciprocate axially along the cylinder body 1 and always has a tendency to move outwards. The outer end of the pin 2 is magnetic, and the open end of the cylinder body 1 is screwed and fitted with an adjusting block 3 that can be fed axially along the cylinder body 1 through rotation. The adjusting block 3 is cylindrical, and the outer end of the limit pin 2 It is in the shape of a round head and penetrates and extends out of the adjustment block 3. The limit pin 2 has a limit portion 21. The limit portion 21 and the inner end of the adjustment block 3 are axially limited and abutted along the circumferential direction to form a limit. , the limit pin 2 cooperates with the cylinder body 1 along the circumferential direction, and when the limit pin 2 is controlled to move inward, the adjustment block 3 c...

Embodiment 2

[0055] like Figure 7-11 As shown, this embodiment is basically the same as the first embodiment, the difference is that: the inner side wall of the cylinder body 1 has two vertically arranged notch grooves 5, and the outer peripheral surface of the limit pin 2 has two along the limit pin 2 The axially arranged rib 4, the notch groove 5 cooperates with the rib 4 and makes the limit pin 2 form a limit along the circumferential direction, when the limit pin 2 is controlled to move inward, the rib 4 and the notch groove 5 can be separated and separated Release the circumferential limit. A vertically arranged notch groove 5 is provided on the inner side wall of the cylinder body 1, and a convex rib 4 is arranged on the outer peripheral surface of the limit pin 2 along the axial direction of the limit pin 2. The notch groove 5 cooperates with the convex rib 4 to make the limit The position pin 2 forms a circumferential limit, so that when the limit pin 2 is controlled to move inwa...

Embodiment 3

[0057] like Figure 12 As shown, this embodiment is basically the same as the first embodiment, the difference is that: the limit pin 2 includes a limit cylinder 23 and a ball 24 that is located in the limit cylinder 23 and always has a tendency to move outward, and the ball 24 is a metal iron The ball 24 and the inner edge of the outer end of the limiting cylinder 23 axially limit and abut, and the ball 24 partially protrudes from the outer end of the limiting cylinder 23 . By setting the limit pin 2 to include a limit cylinder 23 and a ball 24, the ball 24 partially protrudes from the outer end of the limit cylinder 23, and the ball 24 is continuously subjected to an outward force so that it can cooperate with the positioning groove at the bottom of the door body to limit the limit When the door body moves relative to the limit pin 2, the balls 24 can roll along the bottom surface of the door body, thereby reducing the movement resistance, making the movement smoother and re...

Abstract

The invention provides an adjustable door stopper assembly, which belongs to the technical field of door stoppers. It solves the technical problems of inconvenient and poor stability of the existing door stopper. The adjustable door stopper assembly includes a cylinder with an open end, and a limit pin that can reciprocate axially along the cylinder and always has a tendency to move outward is arranged in the cylinder, and the open end of the cylinder The screw connection is equipped with an adjustment block that can be fed along the axial direction of the cylinder through rotation. The outer end of the limit pin is in the shape of a round head and penetrates and extends out of the adjustment block. There is a limit portion on the limit pin. The limit part can abut against the inner end of the adjustment block in the axial direction and form a limit in the circumferential direction, and the limit pin can cooperate with the cylinder in the circumferential limit. When the limit pin moves inward, the adjusting block can release the circumferential limit or the limit pin can release the circumferential limit. The adjustable door stopper assembly ensures the convenience of adjustment and ensures a more stable state after adjustment.

Description

technical field [0001] The invention belongs to the technical field of door hardware, and relates to an adjustable door stopper assembly. Background technique [0002] The door blocking device is a device that holds the door body in position after the door body is opened, so as to prevent the wind blowing or touching the door leaf and closing it. [0003] For example, the Chinese patent with the authorization announcement number CN204098659U discloses a new type of door suction, including a suction seat that can be fixed on the ground and a suction cup that can be fixed on the door, characterized in that the suction seat is composed of a cylindrical plastic backsheet and a plastic backsheet It consists of a quarter sphere extending upward, the bottom plane of the quarter sphere is connected with the plastic film, the side plane is the door suction surface corresponding to the door, and the door suction surface is provided with a magnet installation A strong magnet is fixed ...
