Description

Safety armrest Technical Field The utility model relates to the technical field of climbing auxiliary tools, in particular to a safety handrail. Background Some equipment work platforms are much higher than the ground, requiring safety armrests for operator climbing during the operator climbing process. In the prior art, the safety handrail is generally in a fixed railing structure, and cannot be retracted when the safety handrail is not used at ordinary times, so that more platform space is occupied, and therefore, a safety handrail capable of saving the working space of the platform is needed. Disclosure of utility model Therefore, the technical problem to be solved by the utility model is to overcome the problem that the safety handrail in the prior art cannot be stored, so that excessive platform space is occupied, and therefore, the safety handrail capable of saving the working space of the platform is provided. In order to solve the above technical problems, the present utility model provides a safety handrail, comprising: the base, wear to be equipped with on the base: the body of rod, the body of rod is followed the base slides and sets up, the base with all be equipped with on the body of rod: limiting holes are formed in the limiting holes in a penetrating mode: The gag lever post, one side of base still is connected with: The bottom of the rod body penetrates through the base to be connected with the first end of the coil spring, the second end of the coil spring is connected with the base, and when the rod body slides along the base, the coil spring is in a deformation state. As a further improvement of the utility model, a sheath is arranged between the base and the rod body, and the limiting rod passes through the sheath and is connected with the limiting hole. As a further improvement of the utility model, a blind hole is arranged on the sheath, an adjusting bolt is penetrated in the blind hole, an adjusting nut is arranged on the outer side of the base, and the adjusting nut is sleeved on the adjusting bolt and is in threaded fit with the adjusting bolt. As a further development of the utility model, the sheath consists of two plates with U-shaped cross-section. As a further improvement of the utility model, the top of the rod body is also provided with a transverse handrail part. As a further improvement of the utility model, the surface of the limiting rod is provided with external threads, the base is provided with a limiting nut at the outer side of the limiting hole, and the external threads of the limiting rod are in threaded fit with the limiting nut. As a further improvement of the utility model, the limiting rod is provided with a pull ring, and the pull ring is positioned at the outer side of the base. As a further improvement of the utility model, the top of the base is provided with a cover plate. Compared with the prior art, the technical scheme of the utility model has the following advantages: when the safety handrail is used, the rod body is lifted up along the base by pushing the rod body upwards until the limiting hole on the rod body is aligned with the limiting hole on the base, the limiting rod is inserted into the limiting hole, the rod body is locked, the operation platform can be lifted up by virtue of the force exerted by the rod body at the moment, after the operation is finished, the limiting rod is pulled out of the limiting hole, and the rod body is pushed downwards to enable the rod body to naturally fall back, so that storage can be completed, a certain platform space is saved, and the space utilization rate is improved.
