DETAILED DESCRIPTION

[0013] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, obvious and understandable, the specific embodiments of the utility model are described in detail below in conjunction with the drawings. In the following description, a large number of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed base body implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] The specific embodiments of the utility model are further described in detail below in conjunction with the drawings.

[0016] By Figures 1 to 5 It is given, including the bottom plate 1, the upper end of the bottom plate 1 is provided with the positioning plate 3 through two upper and lower axial fixed columns 2, the upper end of the positioning plate 3 is provided with the fixed plate 4, the upper end of the fixed plate 4 is provided with the rotating column 5 of upper and lower axial on the left and right sides respectively, the clamping claw 6 is rotatably connected on the rotating column 5, the clamping roller 7 is rotatably connected on the front end of the clamping claw 6, the upper sliding block 8 is slidably connected on the upper end of the fixed plate 4 between the two clamping claws 6, the backrest block 9 is provided on the front end of the upper sliding block 8, the inclined surface of the upper and lower end faces of the upper sliding block 8 is gradually inclined inward from back to front, the reset roller 10 is rotatably connected on the rear end of the clamping claw 6 and contacts with the inclined surface of the upper sliding block 8, the baffle 11 is provided on the rear end of the fixed plate 4, the baffle 11 is slidably connected with the upper sliding block 8 through two guide columns 12 on the front end, the spring 13 is sleeved on the guide column 12 between the baffle 11 and the upper sliding block 8.

[0017] In order to facilitate positioning, the bottom plate 1 upper end is equipped with a base 14.

[0018] In order to facilitate clamping, the backrest block 9 front end is an arc surface, and the area between the backrest block 9 front end surface and the two clamping rollers 7 can form a circle coaxial with the base 14.

[0019] In order to avoid scratching the cylinder, the clamping rollers 7 and the backrest block 9 are made of nylon material.

[0020] In order to facilitate the upper sliding block 8 sliding, the fixed plate 4 upper end is equipped with a moving slide rail 15, and the upper sliding block 8 lower end is equipped with a sliding sleeve block 16 cooperating with the moving slide rail 15.

[0021] In order to prevent the clamping claw 6 from rubbing with the fixed plate 4, the rotating column 5 is equipped with a gasket 17 below the clamping claw 6.

[0022] When the cylinder needs to be clamped and fixed, the cylinder to be fixed is moved from the front to the back of the two clamping rollers 7, and after moving a distance, the cylinder contacts the two clamping rollers 7 and extrudes them outward. Due to the positioning effect of the rotating column 5, the cylinder extruding the clamping rollers 7 swings outward, the front end of the two clamping claws 6 swings outward, and the rear end of the two clamping claws 6, i.e. the reset roller 10, swings inward. Since the reset roller 10 contacts the inclined surface of the upper sliding block 8, the reset roller 10 extrudes the upper sliding block 8 when it swings inward, which makes the upper sliding block 8 move backward, and the sliding sleeve block 16 moves backward on the moving slide rail 15. The upper sliding block 8 moves upward and extrudes the two springs 13, continuously moving the cylinder backward. When the cylinder moves backward to the rear of the two clamping rollers 7, the area between the two clamping rollers 7 and the backrest block 9 is located in the area.

[0023] At this time, the two clamping rollers 7 lose the extrusion force of the cylinder, which makes the two reset rollers 10 release the extrusion of the upper sliding block 8. At the same time, due to the forward restoring force of the two springs 13, the upper sliding block 8 slides forward. After the upper sliding block 8 slides forward for a distance, the arc surface of the backrest block 9 contacts the outer surface of the cylinder. At the same time, due to the forward sliding of the upper sliding block 8, the rear end of the two clamping claws 6 swings outward, which makes the front end of the two clamping claws 6 swing inward, and the two clamping rollers 7 swing inward by a certain angle and contact and clamp the left and right sides of the cylinder. At the same time, the backrest block 9 also extrudes the cylinder forward. At this time, the backrest block 9 and the two clamping rollers 7 cooperate to clamp and fix the cylinder. At this time, the lower end of the cylinder is inserted into the base 14, and the cylinder can be transported. When the cylinder needs to be taken out after the transportation is completed, the cylinder is taken off from the base 14 and pulled forward, which makes the front end of the clamping claw 6 swing outward, and the backrest block 9 moves backward, releasing the clamping and fixing of the cylinder.

[0024] Compared with the prior art, the beneficial effects of the utility model are that the clamping roller, backrest block and clamping claw provided can realize fixing and limiting of the oil cylinder during transfer, prevent shaking and falling during transfer to cause damage of the oil cylinder, and can be suitable for clamping oil cylinders of different sizes and models.

[0025] It should be noted that, according to the needs of implementation, each component described in the embodiments of the utility model can be split into more components, or two or more components or parts of components can be combined into new components, to achieve the purpose of the embodiments of the utility model.

[0026] The above embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the utility model. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
