Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydraulic wrenches, and particularly relates to a manual anti-pinching device for a hydraulic wrench head. Background Art
[0002] A high-power hydraulic wrench generally refers to a bolt tightening tool that can output and set torque. It is a high-pressure hydraulic tool and is widely used in equipment maintenance and installation in multiple wind power equipment fields.
[0003] The head of a traditional hydraulic wrench is prone to slipping and not being close to the arm during use, which can cause serious injuries such as squeezing to the user's hand. However, there is currently no better protective gear, so the above-mentioned low safety problem still exists in actual work. Utility Model Content
[0004] The purpose of the utility model is to provide a manual anti-pinch device for a hydraulic wrench head, so as to solve the problem of potential safety hazards in the use of the hydraulic wrench head position proposed in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a manual anti-pinch device for a hydraulic wrench head, comprising an outer cover, one end of which is C-shaped and is covered on the hydraulic wrench, and the other end is sleeved and locked on the end of the hydraulic wrench, thereby ensuring that the hydraulic wrench head will not come into direct contact with the human body during processing, thereby avoiding safety problems; a support member, which is detachably fixed to the surface of the outer cover, and the end of the support member extends to the outside of the outer cover. When the outer cover is sleeved on the hydraulic wrench, the support member can be used for support by the staff.
[0006] Preferably, a plurality of screw holes are provided on the outer surface of the outer cover, and the support member is a handrail, and a threaded portion is provided at one end of the handrail, which is screwed into the screw hole to achieve a threaded connection between the two, which can ensure a stable installation and normal disassembly, and the installation position of the handrail can be adjusted according to the support needs.
[0007] Preferably, the other end of the handrail extends to the outside of the outer cover, and a rubber sleeve is provided at the other end of the handrail, so that the rubber sleeve can improve the comfort of holding when the staff is supporting it.
[0008] Preferably, oil filling grooves are provided on both sides of each screw hole. The cross-section of the oil filling groove is rectangular, and the depth of the oil filling groove is equal to the depth of the screw hole. During long-term use, once rust stains appear at the connection between the threaded part and the screw hole, lubricating oil can be poured into the oil filling groove to facilitate later disassembly.
[0009] Preferably, a rubber sheet is bonded to the inner wall of the outer cover, and the thickness of the rubber sheet gradually increases from the bottom to the top of the outer cover. When the outer cover is used to cover the hydraulic wrench, the rubber sheet can achieve a buffering effect, thereby avoiding collision between the outer cover and the hydraulic wrench caused by rapid installation of the outer cover.
[0010] Preferably, a screw rod passes through the other end of the outer cover, and a nut is sleeved on one end of the screw rod. By rotating the screw rod and the nut, the other end of the outer cover is contracted to achieve a fastening connection with the hydraulic wrench.
[0011] Preferably, the support rod is bent to form an L-shaped structure, and the length of the threaded area is greater than the depth of the screw hole, thereby ensuring that the support rod can be fully connected to the screw hole and avoiding insufficient threaded area to affect the connection strength.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] Through the design of the utility model, the head of the hydraulic wrench can be covered and protected to avoid mechanical damage to the user's hands. At the same time, the tooling can adjust the position of its own handrail according to usage requirements, and has high overall flexibility, which makes up for the safety issues existing in the existing operating methods.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figures 1 to 3 The utility model provides a technical solution: a hydraulic wrench head anti-pinch manual device, including
[0023] The outer cover 100 has a C-shaped opening at one end and is mounted on the hydraulic wrench, while the other end is locked on the end of the hydraulic wrench to ensure that the hydraulic wrench head does not come into direct contact with the human body during processing, thereby avoiding safety problems.
[0024] The support member is detachably fixed to the surface of the outer cover 100 , and the end of the support member extends to the outside of the outer cover 100 . When the outer cover 100 is sleeved on the hydraulic wrench, the support member can be used for support by the staff.
[0025] In this embodiment, preferably, a plurality of screw holes 100a are provided on the outer surface of the outer cover 100, and the support member is a handrail 200. A threaded portion 200a is provided at one end of the handrail 200, and the threaded portion 200a is screwed into the screw hole 100a to achieve a threaded connection between the two, which can ensure a stable installation and enable normal disassembly, and the installation position of the handrail 200 can be adjusted according to the support needs.
[0026] In this embodiment, preferably, the other end of the handrail 200 extends to the outside of the outer cover 100, and a rubber sleeve 201 is provided at the other end of the handrail 200. When the staff supports the handrail, the rubber sleeve 201 can improve the comfort of holding the handrail.
[0027] In this embodiment, preferably, oil filling grooves 100b are opened on both sides of each screw hole 100a. The cross-section of the oil filling groove 100b is rectangular, and the depth of the oil filling groove 100b is equal to the depth of the screw hole 100a. During long-term use, once rust stains are generated at the connection between the threaded portion 200a and the screw hole 100a, lubricating oil can be poured into the oil filling groove 100b to facilitate subsequent disassembly.
[0028] In this embodiment, preferably, a rubber sheet 101 is also bonded to the inner wall of the outer cover 100, and the thickness of the rubber sheet 101 gradually increases from the bottom to the top of the outer cover 100. When the hydraulic wrench is covered by the outer cover 100, the rubber sheet 101 can achieve a buffering effect, thereby avoiding collision between the outer cover 100 and the hydraulic wrench due to rapid installation.
