Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline dredging, and particularly relates to a firing auxiliary device. Background Art

[0002] At present, toilets, sewers and other pipes are occasionally clogged in family life. Pipe blockages can usually be solved by using chemical substances to dissolve them, flexible ropes to dredge them, or by using gas that instantly releases a certain pressure to dredge them.

[0003] Devices that release gas to clear a blockage typically require the gas to be compressed, similar to how a pump works when pumping air into a ball or tire. The gas is then pumped into a reservoir and a trigger is pressed to release the gas, using the pressure to flush the blockage.

[0004] However, due to the effect of gas pressure, it takes a certain amount of force to press the firing device of the pipe cleaner, which makes it difficult for some people with less strength to use this type of pipe cleaner. Utility Model Content

[0005] The purpose of the utility model is to provide a firing auxiliary device to solve the problem that a certain amount of force is required to press the firing device of the current pipe dredge, making it difficult for some people with less strength to use it.

[0013] Furthermore, a buckling chute is also provided in the middle section of the dredge.

[0014] The sliding part is accommodated in the buckling chute, and the sliding part is slidably connected with the buckling chute.

[0030] In order to better understand the purpose, structure and function of this utility model, Figures 1 to 5 , a firing assist device of the present invention is further described in detail.

[0031] like Figure 1 As shown, a firing assist device of an embodiment of the present invention is provided with a buckling assembly 100 and a vertical pressing assembly 200. When the user buckles the buckling assembly 100, the buckling assembly 100 contacts the upper part of the vertical pressing assembly 200, and the buckling assembly 100 can apply a certain force to the vertical pressing assembly 200. The firing assist device is used to assist the firing device of the pipe dredge.

[0032] like Figures 1 to 3 As shown, in the present invention, the buckling assembly 100 also includes a buckling portion 110 and a sliding portion 120, wherein the buckling portion 110 and the sliding portion 120 are fixedly connected; in some embodiments, the buckling portion 110 and the sliding portion 120 are an integrated design, and this integrated design can simplify the production and assembly process.

[0033] The sliding portion 120 is disposed within the pressing chute 310 and is slidably connected to the pressing chute 310. The pressing chute 310 is disposed on the middle section 300 of the dredge. Also located on the same side of the pressing chute 310 are a firing mechanism 350 and a handle 360. The end of the vertical pressing assembly 200, which is closest to the sliding portion 120, also extends into the pressing chute 310. A limiting through-hole 311 is provided on each side of the end of the pressing chute 310 that is away from the vertical pressing assembly 200. Furthermore, the sliding portion 120 is further provided with a limiting groove 121 at the end away from the vertical pressing assembly 200. A limiting rod 320 extends through the two limiting through-holes 311 and is accommodated in the limiting groove 121. The limiting rod 320 can limit the sliding part 120 to prevent the sliding part 120 from sliding out of the buckling slide groove 310. The coupling between the limiting rod 320 and the limiting groove 121 can reduce the offset of the sliding part 120 in the slide groove in a direction perpendicular to the length direction of the limiting groove 121 and the length direction of the limiting rod 320, thereby improving the stability of the buckling assembly 100.

[0034] When the pressing assembly 100 contacts the upper portion of the vertical pressing assembly 200, one end of the sliding portion 120 contacts the upper portion of the vertical pressing assembly 200. The lower middle portion of the vertical pressing assembly 200 is located near the triggering mechanism 350. When the sliding portion 120 applies pressure to the vertical pressing assembly 200, the vertical pressing assembly 200 contacts and applies pressure to the triggering mechanism 350. The end of the vertical pressing assembly 200 that is away from the sliding portion 120, i.e., the lower end of the vertical pressing assembly 200, is connected to the middle section 300 of the plumbing cleaner.

[0035] To ensure a more stable connection between the vertical pressing assembly 200 and the middle section 300 of the plumber, a rotation groove 330 is provided on the middle section 300 of the plumber, and second rotation holes 331 are provided on both sides of the rotation groove 330. At the same time, a first rotation hole 210 is provided at the end of the vertical pressing assembly 200 away from the sliding portion 120. In addition, a rotation rod 340 is provided, which passes through the first rotation hole 210 and the second rotation hole 331, allowing the vertical pressing assembly 200 to be rotatably connected to the rotation rod 340. This design also restricts the movement direction of the vertical pressing assembly 200 to a certain extent, improving the stability of the vertical pressing assembly 200.

[0036] When firing the gun during use, the user holds the pressing portion 110 with their fingers and applies a certain force toward the vertical pressing assembly 200. The pressing portion 110, under the force toward the vertical pressing assembly 200, drives the sliding portion 120 to move. Since the sliding portion 120 is disposed within the limiting groove 121, the sliding portion 120 can only move toward the vertical pressing assembly 200, contact the vertical pressing assembly 200, and apply a certain pressure to the vertical pressing assembly 200. Under the pressure of the sliding portion 120, the upper portion of the vertical pressing assembly 200 is rotationally limited by the rotating rod 340, and the vertical pressing assembly 200 moves toward the firing mechanism 350. After the lower middle portion of the vertical pressing assembly 200 contacts the firing mechanism 350, the sliding portion 120 still applies pressure to the vertical pressing assembly 200, and thus the vertical pressing assembly 200 also continues to apply pressure to the firing mechanism 350. When the pressure on the firing mechanism 350 reaches the pressure value that allows firing, the firing mechanism will fire. The user then releases the finger holding the pressing portion 110, releasing the pressure on the pressing portion 110, and the sliding portion 120 releases the pressure on the vertical pressing assembly 200. Subsequently, due to the combined effect of the thrust of the firing mechanism 350 on the vertical pressing assembly 200 when it returns to the ready-to-fire state and the recovery of the vertical pressing assembly 200 from the deformed state, the upper portion of the vertical pressing assembly 200 pushes the sliding portion 120 to slide in the direction of the limiting groove 121. Subsequently, the vertical pressing assembly 200 releases the pressure on the firing mechanism 350 or even breaks contact, and the entire firing assist device returns to the ready-to-use state. When a user applies force to the pressing portion 110, the point where the sliding portion 120 contacts the vertical pressing assembly 200 is the force-applying point, the point where the vertical pressing assembly 200 contacts the firing mechanism 350 is the force-receiving point, and the point where the vertical pressing assembly 200 contacts the rotating rod 340 is the fulcrum. The distance from the force-applying point to the fulcrum is l1, and the distance from the force-receiving point to the fulcrum is l2. Assuming the critical force required for the firing mechanism 350 to achieve firing is F2, and the pressure applied by the user to achieve firing is F1, according to the lever principle, F1×l1=F2×l2, where l1>l2. Therefore, F1<F2, meaning that the maximum force applied by the user to achieve firing is less than the maximum force required by the firing mechanism 350 to achieve firing, thereby achieving the goal of achieving firing with less force.

[0037] like Figure 4As shown, in some embodiments, a firing portion groove 220 is provided on one side of the vertical pressing assembly 200 close to the firing device 350, and a portion of the firing device 350 can be accommodated in the firing portion groove 220. During the firing process, the firing portion groove 220 can limit the vertical pressing assembly 200 to a certain extent, so that the foundation of the vertical pressing assembly 200 and the firing device 350 is more stable, avoiding the offset of the firing device 350 and the vertical pressing assembly 200, and improving the stability of the firing auxiliary device.

[0038] It can be understood that the buckling portion 110 is designed to be a circular structure, which makes it more convenient for the user to buckle. The contact surface between the buckling portion 110 and the user's fingers is larger, which is more conducive to operation.

[0039] like Figure 5 As shown, in the present invention, the middle section 300 of the clearing tool is also provided with a handle portion 360, which is provided on one side of the clamping assembly 100 and the vertical pressing assembly 200 for the user to hold. An inflation assembly 400 is also provided at the end of the clearing tool middle section 300 away from the clamping assembly 100. An inflation rod 500 is provided at the end of the inflation assembly 400 away from the middle section 300 of the clearing tool, a portion of which extends into the inflation assembly 400. An inflation handle 600 is also provided at the end of the inflation rod 500 away from the inflation assembly 400. An air storage and transmission assembly 700 is also provided at the end of the clearing tool middle section 300 close to the clamping assembly 100. During use, the user presses the inflation handle 600 to press air into the air storage and transmission assembly 700, so that the air storage and transmission assembly 700 stores gas at a certain pressure. This process is similar to the process of using an air pump to inflate a wheel or a ball. After the firing device 350 is fired, the compressed air in the air storage and delivery assembly 700 will be transported to the outside of the air storage and delivery assembly 700 through the end of the air storage and delivery assembly 700 away from the middle section 300 of the clearing device, and the compressed air can be used to clear the pipeline.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
