Abstract
Description
Technical Field
[0001] The utility model relates to the field of industrial door openers, and relates to a structure of an industrial door opener. Background Art
[0002] Door openers have different names, but classified by their use, they can generally be divided into: wrought iron door openers, courtyard door openers, retractable door openers, garage door openers, revolving door openers, hanging door openers, rolling shutter door openers, industrial door openers, window openers, etc. Door openers can be divided into AC door openers and DC door openers according to the current. There are also various ways to open the door, such as rotary opening, push-pull opening, etc. When the push-pull opening door is opened and then someone accidentally puts their hand in the gap between the door and the door frame, the hand will be pinched by the door leaf when the door leaf closes. Generally, ordinary doors do not have a buffer structure. Being pinched by the hand will be very painful and extremely likely to cause injury. In severe cases, the finger bones will be directly pinched off.
[0003] Therefore, in order to solve the deficiencies in the prior art, it is necessary to design a structure of an industrial door opener with a simple structure. Summary of the Utility Model
[0004] The utility model provides a structure of an industrial door opener to solve the problems of the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A structure of an industrial door opener includes: a door frame, a push door and a buffer assembly. The push door is slidably arranged on one side of the door frame. The door frame is provided with a slot. A bevel push head is arranged on the left side of the push door. The buffer assembly includes a fixed block, a linkage rod, a Z-shaped push block, an elastic buffer head and a first spring. A through hole is arranged on the left side of the slot. The first spring is arranged in the through hole. The fixed block is fixed inside the slot. The linkage rod slides left and right in the through hole and the fixed block and is located on the right side of the first spring. The Z-shaped push block slides vertically inside the fixed block. The middle part of the Z-shaped push block is sleeved in the inclined through hole in the middle part of the linkage rod. The two bevel push heads are in contact connection with the outer end face of the Z-shaped push block through bevels and are arranged in the same direction. The elastic buffer head is arranged at the right end of the linkage rod.
[0006] Further improvement, the elastic buffer head includes a fixed head, a sliding rod, a buffer head and a second spring. The left end of the fixed head is fixed to the right end of the linkage rod. The sliding rod slides in the slideway of the fixed head. The buffer head is fixed to the right end of the sliding rod. The second spring is sleeved on the sliding rod and is located between the fixed head and the buffer head.
[0007] Further improvement, a limiting part is arranged at the left end of the sliding rod, and a plug cover is threadedly connected to the right end of the fixed head.
[0008] For further improvement, two groups of the buffer assembly and the inclined plane push head are symmetrically arranged.
[0009] Compared with the prior art, the beneficial effects of the industrial door opener structure of the present utility model are as follows:
[0010] When the door is pushed to the left to prepare for closing, the inclined plane push head moves leftward, and the inclined plane contacts and pushes the Z-shaped push block downward. The Z-shaped push block stably slides vertically downward in the fixed block. The middle part of the Z-shaped push block is sleeved in the inclined through hole in the middle of the linkage rod. Under the action of the Z-shaped push block, the linkage rod stably moves rightward inside the fixed block, causing the elastic buffer top head to move rightward until it presses against the door, applying a reverse resistance during the door closing process, increasing the reaction time during closing, and thus reducing the risk of pinching hands.

[0018] The following will further elaborate on the technical solution of the present utility model in conjunction with the embodiments and the attached Figures 1 to 4 drawings.
[0019] Embodiment 1
[0020] An industrial door opener structure includes: a door frame 1, a push door 2, and a buffer assembly 3. The push door 2 is slidably disposed on one side of the door frame 1. The door frame 1 is provided with a slot 11. A beveled push head 21 is provided on the left side of the push door 2. The buffer assembly 3 includes a fixed block 31, a linkage rod 32, a Z-shaped push block 33, an elastic buffer head 34, and a first spring 35. A through hole 12 is provided on the left side of the slot 11. The first spring 35 is disposed in the through hole 12. The fixed block 31 is fixed inside the slot 11. The linkage rod 32 is slidably disposed left and right in the through hole 12 and the fixed block 31 and is located on the right side of the first spring 35. The Z-shaped push block 33 is slidably disposed vertically inside the fixed block 31. The middle part of the Z-shaped push block 33 is sleeved in an inclined through hole 321 in the middle part of the linkage rod 32. The two beveled push heads 21 are in contact connection with the outer end surface of the Z-shaped push block 33 through an inclined surface and are arranged in the same direction. The elastic buffer head 34 is disposed at the right end of the linkage rod 32.
[0021] As Figures 1 to 4 shown, the working principle of the present utility model is as follows: When the push door 2 moves to the left to prepare for closing the door, there is still a certain gap between the push door 2 and the door frame 1 at this time. When moving further, the beveled push head 21 moves leftward and contacts the inclined surface and pushes the Z-shaped push block 33 downward. The Z-shaped push block 33 stably slides vertically downward inside the fixed block 31. Since the middle part of the Z-shaped push block 33 is sleeved in the inclined through hole 321 in the middle part of the linkage rod 32, under the action of the Z-shaped push block 33, the linkage rod 32 stably moves rightward inside the fixed block 31, causing the elastic buffer head 34 to move rightward until it presses against the push door 2, applying a reverse resistance during the closing process of the push door 2, increasing the reaction time during closing, and thus reducing the risk of pinching hands; when the push door 2 continues to move leftward, the elastic buffer head 34 is compressed leftward and then the door is closed.
[0022] As a further preferred embodiment, the elastic buffer head 34 includes a fixed head 341, a sliding rod 342, a buffer head 343 and a second spring 344. The left end of the fixed head 341 is fixed to the right end of the linkage rod 32. The sliding rod 342 is slidably disposed in a slideway 345 of the fixed head 341. The buffer head 343 is fixed to the right end of the sliding rod 342. The second spring 344 is sleeved on the sliding rod 342 and is located between the fixed head 341 and the buffer head 343.
[0023] After the buffer head 343 contacts the door push 2, a reverse resistance is applied to the door push 2 through the cooperation of the second spring 344 and the sliding rod 342.
[0024] As a further preferred embodiment, a limiting portion 346 is provided at the left end of the sliding rod 342, and a plug cap 347 is threadedly connected to the right end of the fixed head 341. Through the cooperation of the limiting portion 346 and the plug cap 347, the sliding rod 342 can be prevented from falling off.
[0025] As a further preferred embodiment, two sets of the buffer assembly 3 and the inclined surface push head 21 are symmetrically arranged.
[0026] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the protection scope determined by the claims.
