Description

Mopping machine handle tilt adjustment mechanism

technical field

The utility model relates to a ground cleaning device, in particular to a tilting adjustment mechanism of a handle of a floor mopping machine.

Background technique

The existing mopping machines all include an adjustable operating handle. The operator can adjust the height and angle of the operating handle to achieve the best use effect. Therefore, how to adjust the operating handle quickly, conveniently and easily The fixed position of the operating handle plays a vital role in reducing the labor intensity of the operator and improving work efficiency.

Now the common operating handle adjustment methods on the market are divided into the following types:

The first type is a mopping machine adjusted by a clamp block (see Figure 1), including a base 1, a support frame 93, a handle connecting pipe 2, a clamp block 92, an adjustment handle 91 and an operating handle 3, and the lower end of the handle connecting pipe 2 is rotated and connected On the base 1, the clamp block 92 is slidably connected to the handle connecting pipe 2, the lower end of the support frame 93 is rotatably connected to the base 1, the upper end of the support frame 93 is connected with the clamp block 92, the clamp block 92 is provided with an adjustment handle 91, and the operating handle 3 is installed on the top of the handle connecting pipe 2; when the adjusting handle 91 is loosened, the clip 92 can slide on the handle connecting pipe 2, and the height and angle of the operating handle 3 can be adjusted. When the operating handle 3 is adjusted to a proper position, the lock Tighten the adjustment handle 91, the clamp block 92 clamps the handle connection pipe 2, and the position of the operating handle 3 is fixed; but this adjustment method has a major disadvantage: the operator is inconvenient to operate, and needs to bend over to lock or loosen the adjustment handle 91, Increase the labor intensity of the operator.

The second type is a mopping machine adjusted by gears (see Figure 2), including a base 1, a gear 83, a movable gear rod 82, a handle connecting pipe 2, an operating handle 3 and a pull handle 81, and the handle connecting pipe 2 is connected to the base by rotation 1, between the handle connecting pipe 2 and the base 2, there is also a gear 83 and a movable rack 82 that cooperate with each other. The gear 83 is fixed on the base 1, and the movable rack 82 is installed on the lower part of the handle connecting pipe 2. At the top of the handle connecting pipe 2, a pull handle 81 is located on the operating handle 3, and the pull handle 81 controls the movable tooth bar 82 to move up and down; Angle and height are adjusted, when adjusted to a suitable position, unclamp the handle 81, the movable gear bar 82 meshes with the gear 83, and the position of the operating handle 3 is fixed; but this method has obvious disadvantages: 1. Because the gear 83, The assembly requirements of the movable rack 82 and related accessories are high, resulting in an increase in cost. 2. There is an adjustment blind zone between the gear 83 and the movable rack 82 (the two teeth cannot be meshed), and the adjustment position is limited. 3. Due to the manufacturing and assembling accuracy of the gear 83 and the movable rack 82, there is still a gap after the meshing, which will cause the operating handle 3 to shake and affect the operation.

Therefore, a tilting adjustment mechanism of the floor mopping machine handle that is convenient to adjust and fix, the adjustment area is not limited, and will not shake after being fixed is lacking in the current market, and has its unique economic and market value.

Compared with the prior art, the beneficial effects of the utility model are as follows: 1. The tilting adjustment mechanism of the handle of the utility model can easily and quickly adjust the position of the operating handle; 2. The utility model tilts the handle of the scrubber Adjustment mechanism, in the adjustment area, the adjustment position will not be restricted, and infinite adjustment can be achieved; 3. The tilt adjustment mechanism of the handle of the floor mopping machine of the utility model can firmly fix the handle connecting pipe, so that the operating handle does not need to be adjusted during use. will shake.
