Description

Technical Field

[0001] The utility model relates to the technical field of universal wheels, in particular to a novel self-locking universal wheel. Background Art

[0002] Universal wheels are so-called movable casters, and their structure allows 360-degree horizontal rotation. Casters are a general term, including movable casters and fixed casters. Fixed casters do not have a rotating structure and cannot rotate horizontally but only vertically. Casters are widely used, such as in luggage, strollers and other products, and universal wheels are used in most application locations. Currently, universal wheels can be locked by the built-in brake plate so that they cannot rotate vertically, thereby ensuring that the main body such as luggage or strollers is not easy to move, but the horizontal 360-degree rotation of the universal wheel cannot be locked, which also brings certain inconveniences to daily use. Utility Model Content

[0003] The cam is provided with a plurality of locking plates, the locking plates being arranged on the cam face and the locking plate being connected to the locking cam by the locking cam. The locking pin is engaged with the locking cam of the locking cam and is engaged with the locking cam of the cam, so that the locking cam can be locked in the locking cam of the cam and the locking cam can be locked in the locking cam of the cam.

[0004] As a preferred solution of the utility model, a limiting groove is provided on the circumferential wall at the lower end of the rotating shaft, and a fixed buckle block is fixedly connected to the upper end. The limiting pin shaft slides correspondingly in the limiting groove, and the rotating connecting seat is fixedly connected to the fixed buckle block.

[0005] As a preferred solution of the utility model, the inner side surface of the roller is evenly arranged and fixedly connected with buckle teeth on the circumference, and buckle locking columns are fixedly connected with buckle locking columns on both sides of the lower end of the self-locking plate, and the buckle locking columns correspond to the buckle teeth. When the self-locking plate is in the non-locking position, the buckle locking columns are disengaged from the buckle teeth, and the roller can rotate on the roller shaft. When the self-locking plate is rotated to the locking position, the lower end of the self-locking plate is buckled in the buckle groove and fixed by the buckle boss, making it difficult to rotate, and the buckle locking column is buckled and inserted between the buckle teeth, thereby preventing the roller from rotating.

[0006] The beneficial effects of the utility model are as follows: the utility model provides a locking pin on the main mounting seat, drives the locking pin to move up and down through the self-locking plate, and uses the locking pin to move up and fit into the side of the rotating connecting seat to lock the main mounting seat, so that the main mounting seat cannot rotate on the rotating shaft, thereby realizing self-locking of the horizontal rotation of the roller, making the universal wheel a directional wheel. In addition, a buckle locking column can also be added to the self-locking plate, and the buckle teeth provided on the roller can be used to lock the roller, so that the roller cannot roll. In actual applications, different accessories can be selected as needed to realize universal rotation locking, roller rolling locking and synchronous locking of the universal wheel, so that the universal wheel has a better self-locking effect, is suitable for more scenarios, has strong applicability and is easy to use.

DETAILED DESCRIPTION

[0013] Example 1

[0014] like Figures 1 to 5 As shown, a new self-locking universal wheel of the utility model is provided with a mounting groove 101 in the middle of the main mounting seat 1, and a latch sliding hole 105 is vertically provided and connected to the mounting groove 101, a buckle groove 102 is provided on the main mounting seat 1 at the lower part of the mounting groove 101, and a buckle boss 103 is fixedly connected at the notch of the front part of the buckle groove 102, roller shafts 104 are fixedly connected on both sides of the main mounting seat 1, and a roller 2 is rotatably connected to the roller shaft 104, and a shaft mounting hole 106 is vertically provided on the rear side of the main mounting seat 1, and a limit pin hole 107 is provided on the side surface of the lower end of the shaft mounting hole 106, and the shaft mounting hole 106 is connected with the middle part of the limit pin hole 107, a self-locking plate 3 is rotatably connected to the mounting groove 101 through a pin shaft, a push-pull slot 301 is provided on the side surface of the middle part of the self-locking plate 3, and a locking latch 4 is slidably installed in the latch sliding hole 105. The locking pin 4 is L-shaped, and a push-pull plate 401 is fixedly connected to its lower end. The push-pull plate 401 is correspondingly buckled and inserted in the push-pull slot 301. A ball 8 is placed at the bottom of the shaft mounting hole 106, and a shaft 5 is rotatably inserted in the shaft mounting hole 106. A limiting groove 501 is provided on the circumferential wall at the lower end of the shaft 5, and a fixed buckle block 502 is fixedly connected to the upper end. The lower end of the shaft 5 is pressed on the ball 8, and the upper end extends out of the shaft mounting hole 106 and is fixedly connected to a rotating connecting seat 6 through a fixed buckle block 502. The entire universal wheel is installed to the bottom of other products through the rotating connecting seat 6, and the main mounting seat 1 can rotate on the shaft 5. A limiting pin shaft 7 is fixedly inserted in the limiting pin hole 107, and the limiting pin shaft 7 is correspondingly slidably buckled in the limiting groove 501, so that the shaft 5 can rotate in the shaft mounting hole 106 and cannot be pulled out.

[0015] When the self-locking plate 3 is in a vertical state on the main mounting seat 1, the locking pin 4 is retracted in the pin sliding hole 105, and it is in an unlocked state at this time. After the self-locking plate 3 is rotated to a certain angle, the lower end is buckled in the buckle groove 102 and is buckled and fixed by the buckle boss 103, so that it is not easy to rotate. At the same time, the push-pull plate 401 is pushed by the push-pull slot 301 to push the locking pin 4 upward. The bottom frame of the rotating connecting seat 6 is polygonal and its edge corresponds to the side of the locking pin 4, so that after the locking pin 4 moves upward, its side will be buckled on the polygonal bottom frame of the rotating connecting seat 6, thereby buckling on the rotating connecting seat 6, so that the main mounting seat 1 cannot rotate around the rotating shaft 5, and it is in a locked state of horizontal rotation of the universal wheel.

[0016] The inner side surface of the roller 2 is evenly arranged and fixedly connected with buckle teeth 201, and the two sides of the lower end of the self-locking plate 3 are fixedly connected with buckle locking columns 302, and the buckle locking columns 302 correspond to the buckle teeth 201. When the self-locking plate 3 is in the non-locking position, the buckle locking columns 302 are disengaged from the buckle teeth 201, and the roller 2 can rotate on the roller shaft 104. When the self-locking plate 3 is rotated to the locking position, the lower end of the self-locking plate 3 is buckled in the buckle groove 102 and fixed by the buckle boss 103, making it difficult to rotate, and the buckle locking columns 302 are buckled and inserted between the buckle teeth 201, thereby preventing the roller 2 from rotating, thereby locking the rolling of the roller 2.

[0017] In practical applications, a locking pin 4, a self-locking plate 3 with a push-pull slot 301, or a self-locking plate 3 with a push-pull slot 301 and a buckle locking column 302 can be optionally installed as needed, so as to achieve locking of only the horizontal rotation of the universal wheel, locking of only the rolling of the universal wheel roller, or locking of both the horizontal rotation of the universal wheel and the rolling of the roller.
