Forward and backward joystick device

Abstract

The invention relates to a forwards and backwards moving control handle device which is mainly used for a non-driven scrubber capable of moving forwards and backwards. A left control handle (1), a right control handle (2) and a middle connecting rod (3) are connected, an extension rod (4) is arranged in the middle of the middle connecting rod, one end of a reset spring (5) is connected with an installing plate (8), the other end of the reset spring is connected with the extension rod (4), and an upper microswitch (6) and a lower microswitch (7) are installed on an installing plate and located on the two sides of the extension rod respectively. The forwards and backwards moving control handle device has the advantages of reducing the occupied space, saving machining cost, reducing mounting, demounting and maintenance labor hours and the like.

Description

technical field [0001] The invention relates to a non-driving floor washing machine operating device, in particular to a forward and backward control handle device. Background technique [0002] With the development of the economy, the continuous improvement of the society's requirements for cleaning, the continuous increase of the cost of employing labor and the continuous improvement of cleaning technology, now there are various types of cleaning and maintenance in the field of cleaning and maintenance of various hard floors such as floors, tiles, and marble. Floor machine, its working principle is generally that a motor is equipped in the head part to drive the brush disc to rotate, and the ground is rotated to clean, while the brush disc rotates, clean water flows to the center hole of the brush disc, so that the brush disc rotates while washing Brush to make the stains, oil stains and impurities on the ground cleaner, and then recycle the sewage that has been washed on ...

AI Technical Summary

Problems solved by technology

However, the structure, installation, maintenance, disassembly and operation of the forward and backward control handle devices on many washing machines are not satisfactory.

[0003] At present, there are various structures on the market. There is a push-button structure. You need to press the forward button, and then straighten the direction of the machine, so that the machine can move in the direction you want. Machine, the machine is still running at this time, it is easy to cause the machine to deviate and cause danger; there is also a relatively simple forward and backward joystick device that is installed on the control box like our utility model forward and backward handle device. The device first connects a complex cam mechanism at the middle link. When the machine moves forward, the cam mechanism rotates half a circle forward, and when the machine moves backward, the cam mechanism rotates half a circle backward, and the cam mechanism is large in size. It is fixed on the mounting plate with bolts. Secondly, the mounting plate must form a certain angle with the middle connecting rod. Only when it is adjusted to a certain angle can the operation be light. This device takes up a lot of space, has a complicated structure, high manufacturing cost, and difficult Trouble, but our utility model forward and backward joystick device, due to the different structure and design concept, these problems have been well solved
