Foldable frame handrail of high pressure cleaning machine

Abstract

The invention discloses a foldable frame handrail of a high pressure cleaning machine. The foldable frame handrail of the high pressure cleaning machine comprises an upper frame body and a lower frame body; the upper frame body is flexibly connected with the lower frame body through a penetrating pin and can rotate around the penetrating pin; the lower frame body is provided with an upper frame body rotation locking mechanism which is formed by a foldable direction locking mechanism and a foldable opposite-direction locking mechanism; the foldable direction locking mechanism is formed by a sliding groove supporting plate, a push rod and a push rod reset spring. According to the foldable frame handrail of the high pressure cleaning machine, the connection strength can be ensured, the operation is convenient, the handrail can be folded and opened conveniently and rapidly without detachment, the integral process is achieved in not more than two seconds, the storage space of the cleaning machine is saved, the storage is easy, and the practicality is quite high.

Description

technical field [0001] The invention relates to a high-pressure cleaning machine frame, in particular to a foldable handrail on the high-pressure cleaning machine frame. [0002] Background technique [0003] The function of a high-pressure cleaner is to generate high pressure in water for cleaning streets, vehicles, etc. Usually, the high-pressure cleaner is placed on a frame, and rollers are arranged under the frame, and a handrail extending backward and upward is provided on one side of the frame, and the movement of the high-pressure cleaner is realized by pushing the handrail. The armrest of the high-pressure cleaning machine frame includes an upper frame body and a lower frame body, the lower frame body is used for connecting with the frame, and the upper end of the upper frame body is flush with the hands for the operator to hold and push. The upper frame and the lower frame of the original handrail are integrally formed without separation. This integral handrail is...

Problems solved by technology

But in the actual application process, this kind of split handrail also has some problems, that is, the connection strength and the convenience of disassembly. In order to increase the connection strength, a relatively complicated structure will be designed at the connection. In this way, disassembly and disassembly It will be time-consuming and laborious to install, which will affect the efficiency. If the structure of the connection is simple, although the disassembly and installation will save time and effort, but there is a danger of bending or even breaking from the connection during the process of moving the cleaning machine, which will affect Normal Use and Lifespan
