Detailed Description
The unidirectional three-roll brake of the present utility model will be described in more detail below in conjunction with the schematic drawings, wherein preferred embodiments of the present utility model are shown, it being understood that one skilled in the art can modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.
The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.
As shown in fig. 1, the embodiment of the utility model provides a unidirectional three-roller brake, which comprises a machine base 1, a unidirectional rotating mechanism 2 arranged in the machine base 1, and three roller rods 3 connected with the unidirectional rotating mechanism 2, wherein each roller rod 3 comprises an inner cylinder 31 connected with the unidirectional rotating mechanism 2 and an outer cylinder 32 with a sliding sleeve arranged outside the inner cylinder 31.
Referring to fig. 2, the end surface of the outer cylinder 32 is rotatably provided with an adjusting rod 33, a torsion spring 34 is connected between the adjusting rod 33 and the inner end surface of the outer cylinder 32, one end of the adjusting rod 33 positioned in the outer cylinder 32 extends to the inner part of the inner cylinder 31 and is provided with a clamping block 35, one side of the inner cylinder 31 is provided with a connecting block 36, and a plurality of clamping grooves 37 matched with the clamping block 35 are formed in the connecting block 36 along the length direction interval of the inner cylinder 31.
The roller rod 3 of the unidirectional three-roller brake provided by the embodiment can be freely adjusted in length according to actual conditions, and the adjustment process is simple and convenient to operate, so that the unidirectional three-roller brake can be used by adapting to inlets with different widths.
Specifically, the length adjustment principle of the roller lever 3 is:
under the action of the torsion spring 34, the clamping block 35 stays in a clamping groove 37 stably, at this time, the length area of the roller rod 3 is not adjustable, when the length of the roller rod 3 is required to be adjusted, the clamping block 35 is driven to be screwed out of the clamping groove 37 matched with the roller rod 3 by rotating the adjusting rod 33, then the adjusting rod 33 can be pulled to drive the outer cylinder 32 to stretch outwards the inner cylinder 31 or push the adjusting rod 33 to drive the outer cylinder 32 to shrink inwards of the inner cylinder 31, the adjustment of the whole length of the roller rod 3 is realized, after the length is determined, the rotating force of the adjusting rod 33 is removed, and under the action of the torsion spring 34, the clamping block 35 is automatically screwed close to the clamping groove 37 and enters the corresponding clamping groove 37, so that the locking of the length of the roller rod 3 is realized, and the whole operation is time-saving and labor-saving.
In a specific embodiment, a limiting block 38 is mounted on an outer side wall of one end of the inner cylinder 31 far away from the unidirectional rotation mechanism 2, a sliding groove 39 is formed on an inner side wall of the outer cylinder 32 along a length direction of the inner cylinder, and the limiting block 38 is slidably mounted in the sliding groove 39.
In the above implementation process, the separation of the inner cylinder 31 and the outer cylinder 32 is avoided by the arrangement of the limiting block 38 and the sliding groove 39.
In a specific embodiment, to avoid slipping when the adjusting lever 33 is rotated, a side wall of one end of the adjusting lever 33 located outside the outer cylinder 32 is provided with anti-slip patterns.
Further, in order to avoid the error touching the adjusting rod 33, a hidden groove 321 is formed on the outer end surface of the outer cylinder 32, one end of the adjusting rod 33 located outside the outer cylinder 32 is located in the hidden groove 321, and a sealing cover 4 is inserted into the hidden groove 321.
