Description

TECHNICAL FIELD

[0001] The utility model relates to a quick-release type oil cylinder limiting plate. BACKGROUND

[0002] The common hydraulic oil cylinder with limiting plate compresses the valve rod to play the role of protecting the oil cylinder when working. The limiting plate is usually fixed by nut tightening. This method is inconvenient to operate when adjusting the relative position of the limiting plate. Especially, the limiting plate needs to be repeatedly disassembled and assembled to adjust the best position. The process of repeatedly disassembling and assembling the nut is complicated, and a wrench is needed for adjustment. This is very troublesome when the limiting plate needs to be replaced in some unexpected situations without a wrench. Therefore, the limiting plate is designed into a quick-release structure when the limiting plate is installed on the oil cylinder with small bearing capacity, so that the disassembly and assembly are more simple and efficient. SUMMARY

[0003] The utility model aims at solving the above technical deficiencies, and provides a quick-release type oil cylinder limiting plate.

[0004] A quick-release type oil cylinder limiting plate, comprising a limiting plate, the bottom of the limiting plate is provided with a connecting sleeve, the connecting sleeve is a split structure, comprising an arc-shaped upper part and a lower part, one end of the upper part and the lower part is hinged, the other end of the upper part and the lower part is respectively provided with a first connecting lug and a second connecting lug, the surface of the first connecting lug and the second connecting lug is provided with a through hole, a bolt is arranged in the through hole and locked by a nut, the outer wall of the nut is provided with a handle.

[0005] Further, the handle and the nut are fixed by welding.

[0006] Further, a gasket is arranged between the nut and the through hole.

[0007] Further, one end of the upper part and the lower part is provided with a through hole, a rotating shaft is arranged in the through hole, and the rotating shaft is a hollow structure with a bolt arranged in the center.

[0008] Further, the limiting plate bottom and the connecting sleeve are fixedly connected by welding.

[0009] Advantages: compared with the prior art, the utility model is suitable for various low-load oil cylinder application scenarios, can reduce the complexity of disassembling and assembling the nut locking type limiting plate, and can make the disassembly and assembly of the limiting plate more convenient without the need of a wrench or other tools. BRIEF DESCRIPTION OF DRAWINGS

[0010] Fig. 1 is a schematic view of a quick-release type oil cylinder limiting plate.

[0011] Fig. 2 This is an assembly diagram of the limit plate plunger valve stem;

[0012] In the diagram, 1 is the limiting plate, 2 is the upper component, 3 is the lower component, 4 is the rotating shaft, 5 is the first connecting ear, 6 is the second connecting ear, 7 is the bolt, 8 is the handle, and 9 is the nut. Detailed Implementation

[0013] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0014] like Figs. 1-2 As shown, the components are: 1. Limiting plate; 2. Upper component; 3. Lower component; 4. Rotating shaft; 5. First connecting ear; 6. Second connecting ear; 7. Bolt; 8. Handle; 9. Nut.

[0015] A quick-release hydraulic cylinder limiting plate includes a limiting plate 1. The bottom of the limiting plate 1 is provided with a connecting sleeve. The connecting sleeve is a split structure, which includes an arc-shaped upper part 2 and a lower part 3. One end of the upper part 2 and the lower part 3 are hinged together. The other end of the upper part 2 and the lower part 3 are respectively provided with a first connecting ear 5 and a second connecting ear 6. The surfaces of the first connecting ear 5 and the second connecting ear 6 are provided with through holes. Bolts 7 are inserted into the through holes and locked by nuts 9. The outer side wall of the nut 9 is provided with a handle 8.

[0016] In this embodiment, the handle 8 and the nut 9 are fixed by welding.

[0017] In this embodiment, a gasket is provided between the nut 9 and the through hole.

[0018] In this embodiment, one end of the upper component 2 and the lower component 3 is provided with a through hole, and a rotating shaft 4 is inserted through the through hole. The rotating shaft 4 is a hollow structure, and a bolt 7 is inserted through its center.

[0019] In this embodiment, the bottom of the limiting plate 1 is fixedly connected to the connecting sleeve by welding.

[0020] Instructions for use: During installation, pass the bolt 7 through the first connecting lug 5, the second connecting lug 6, the washer, and the nut 9 in sequence. Tighten the nut 9 by using the handle 8. When it is necessary to adjust the position of the limit plate 1 or remove the limit plate 1, the nut 9 can be loosened by turning the handle 8. The handle 8 increases the torque of the nut 9, making it easy for personnel to loosen or tighten the nut 9 by hand.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
