Description

Technical Field

[0001] The utility model relates to the field of snowplow start switches, in particular to a snowplow drive switch mechanism which can prevent misoperation. Background Art

[0002] In order to start the snowplow quickly, a switch box is usually set on the handrail of the snowplow, and a start switch and a speed control switch are set on the switch box to start the snowplow and adjust the speed of the snowplow. The start switch of the existing snowplow drive switch mechanism is a button type or a pull cable start. Although the above two methods can quickly start the snowplow, it is easy to start the snowplow due to accidental touch during the specific operation, causing certain safety hazards. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a snowplow drive switch mechanism that prevents misoperation, so as to solve the problem that the start switch of the existing snowplow is prone to misoperation.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A snowplow drive switch mechanism that prevents misoperation includes a switch box installed on a snowplow handrail frame, and a power switch fixedly installed in the switch box. A switch handle is provided below the power switch, one end of which is connected to a switch cable and the other end extends out of the corresponding side of the power switch. An L-shaped enclosure is provided on the side of the switch handle extending out of the power switch, a switch button is provided above the L-shaped enclosure, and a switch block that can move laterally under the action of an external force is slidably installed under the switch button. After the switch button is pressed, the switch block can move downward with the switch button and engage with the L-shaped enclosure at one end close to the switch handle; after the switch cable is pulled, the switch block can translate toward the side of the power switch together with the switch handle that cooperates with it, and trigger the power switch to start. In this way, when in use, the switch button must be pressed first, so that the switch card block connected to it moves down together and engages with the L-shaped enclosure on the switch handle. Then, the switch cable is pulled, and the switch cable moves laterally outside the switch box, thereby driving the switch handle connected to it and the switch card block to move horizontally toward the side of the power switch, and after contacting with the power switch, the power switch is triggered to start. In the above manner, two actions are required to drive the snowplow, thereby preventing misoperation due to accidental contact during operation. The switch card block and the switch handle are compact in structure, and the switch card block can move down after the switch button is pressed, and after engaging with the switch handle, the power switch is triggered together.

[0006] Furthermore, a switch cover is installed above the power switch, and a speed regulating switch assembly is fixedly installed on the switch cover. In this way, by providing the switch cover and installing the speed regulating switch assembly on the switch cover, it is possible to provide both the power switch and the speed regulating switch in one switch box, which is convenient for operators to operate and has a compact overall structure.

[0007] Furthermore, the speed switch assembly is provided with a speed switch button and a plurality of indicator lights. Thus, in use, the speed of the snow sweeping roller can be adjusted by pressing the speed switch button, and the indicator lights can be used to distinguish whether the speed is at a high speed or a low speed.

[0008] Furthermore, the switch box includes an upper box body and a lower box body, four threaded sleeves are arranged in a rectangular shape in the upper box body, four through holes corresponding to the threaded sleeves are arranged on the lower box body, and four guide cylinders corresponding to the threaded sleeves are arranged on the inner side of the lower box body. The lower box body and the upper box body are fixedly connected after bolts pass through the guide cylinders and are threadedly connected with the threaded sleeves. In this way, when in use, the box body can be opened by rotating the bolts to inspect the components in the box body, and this split setting method is also convenient for installation.

[0009] Furthermore, a circular clamping cylinder matching the snowplow handrail frame is provided on the switch box side, and the clamping cylinder is formed by closing the semicircular cylinder of the upper box body and the semicircular cylinder of the lower box body. In this way, when installing the switch box, the semicircular cylinder of the upper box body is first clamped with the handrail pipe, and then the upper and lower box bodies are buckled, and finally the upper box body and the lower box body are locked and fixed by bolts.

[0010] Furthermore, the switch button is assembled on the upper box body, including a key with a return spring at the lower end; a through hole corresponding to the key is provided on the upper box body, and the upper end of the key extends out of the through hole; a mounting block connected to the key and bent downward on both sides is provided under the return spring, and a horizontally arranged slide groove is formed in the middle of the mounting block; the switch card block is composed of a horizontally arranged slide plate and a card block fixed under the slide plate, and the slide plate is slidably installed in the slide groove, and the card block can be engaged with the L-shaped enclosure after moving downward. In this way, when the key is pressed, the return spring will transmit elastic force to the mounting block, and push the mounting block and the switch card block to move downward together, so as to be engaged with the L-shaped enclosure. At the same time, when there is no pressing, the key is returned to its original position by the return spring. The mounting block provided allows the slide plate of the switch card block to slide, so that after moving, it will be against the switch power supply, triggering the switch power supply to start.

[0011] Furthermore, an internal threaded barrel is formed integrally with the button at the lower end, and the return spring is sleeved on the internal threaded barrel; a strip groove is provided on the slide plate, and a positioning bolt is provided under the button, which passes through the strip groove and the mounting block in sequence and is threadedly connected to the internal threaded barrel. In this way, the provided strip groove can guide the sliding of the slider, and the switch handle returns to the initial position after not being pulled by the switch cable. At this time, the L-shaped enclosure of the switch handle is located outside the switch block, and the switch block will fall off from the L-shaped enclosure and move up under the action of the positioning bolt to return to the initial position.

[0012] Furthermore, the switch handle is bent upward at one end near the switch cable to form a bending plate. A spring is provided beside the bending plate and in the switch box body. After the switch cable passes through the spring, it is connected to the bending plate of the switch handle. A strip slide is provided in the middle of the switch handle, and two guide bosses are provided at the bottom of the switch box. The guide bosses are placed in the strip slide. In this way, a spring is provided at the side end of the switch handle. The spring can be compressed after the cable is pulled, and after the switch cable is released, it returns to the initial state, expands, and pushes the switch handle back to the initial position. The provided guide boss can guide the sliding direction of the switch handle so that it can translate under the guidance of the guide boss.

[0013] Furthermore, a switch pad is provided at the bending plate, and the switch cable is connected to the switch pad after passing through the bending plate. In this way, the switch pad is convenient for fixing the end of the switch cable and connecting the end of the switch cable to the switch handle. BRIEF DESCRIPTION OF THE DRAWINGS
