Description

Technical Field

[0001] This utility model relates to the field of snowplows, specifically to a double-bar wheeled snowplow. Background Technology

[0002] The double-bar wheeled snowplow is a tool designed specifically for winter snow removal. Combining a double-bar structure and a wheel design, it features high efficiency, labor-saving, and flexibility, and is widely used for snow removal in roads, parking lots, residential areas, and other places.

[0003] The transmission-driven double-bar wheel snowplow requires disassembling and reinstalling bolts for each adjustment of the lower handle angle and upper handle length. This process is cumbersome, especially in scenarios where frequent adjustments are needed (such as for users of different heights or complex terrain), resulting in extremely low efficiency. Consequently, it is impossible to quickly adjust the angle or length during operation, making it difficult to adapt to unexpected situations (such as changes in slope or differences in snow thickness).

[0004] Therefore, it is necessary to invent a double-barreled wheeled snowplow to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a double-bar wheeled snowplow. By pressing the limiting balls on both sides of the upper handle, the snowplow moves within the limiting holes on both sides of the lower handle. The limiting balls are then inserted into the limiting holes by the fourth spring on the rear side, thus fixing the upper handle in place. Simultaneously, when angle adjustment is needed, pressing the two sets of pull plates outside the connecting sleeve between the lower handles causes the telescopic block to slide within the telescopic rod. As the telescopic block slides, it causes the outer pull plate and the limiting post on the lower side to disengage from the limiting groove in the adjusting bracket. At this point, the entire lower handle can rotate and adjust within the adjusting bracket. After adjustment, releasing the pull plates allows the second spring outside the telescopic rod and the third spring on the rear side of the pull plates to re-insert the limiting post into the limiting groove in the adjusting bracket. This solves the problem in the aforementioned double-bar wheeled snowplow with transmission, where adjusting the angle of the lower handle and the length of the upper handle requires disassembling and reinstalling bolts each time, a cumbersome process, especially in scenarios requiring frequent adjustments, resulting in extremely low efficiency and an inability to quickly adjust the angle or length during operation, making it difficult to adapt to unexpected situations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-bar wheel snowplow, including a pusher plate for pushing snow;

[0007] A steering plate is threadedly connected to the rear side of the push plate. A circular plate is movably sleeved on the upper side of the steering plate. Bolts are threaded through the interior of the circular plate. A main bracket is fixedly connected to the lower side of the circular plate. The circular plate is threadedly connected to the main bracket. Adjustment brackets are fixedly connected to the rear two sides of the main bracket. Limit grooves are opened on the inner surface of the adjustment brackets. Tires are rotatably connected to the two sides of the main bracket.

[0008] A movable rod, hinged inside the adjusting bracket, is used to rotate the lower handle. The movable rod is fixedly connected to the lower handle. A connecting sleeve is fixedly connected to the inner side of the lower handle. A telescopic block is slidably connected inside the connecting sleeve. A telescopic rod is slidably connected inside the telescopic block. A second spring is sleeved on the outside of the telescopic rod. A pull plate is fixedly connected to the front side of the telescopic block. The pull plate is slidably connected to the lower handle. A connecting plate is fixedly connected to the outer end of the telescopic block. A third spring is fixedly connected to both sides inside the connecting plate. A limit post is fixedly connected to the lower outer side of the connecting plate.

[0009] Limiting holes are provided on both sides above the lower handle for adjusting the limit. The lower handle is slidably connected to the upper handle. The upper end of the upper handle is fixedly connected to the grip. The upper handle has a fourth spring on both sides inside. The outer end of the fourth spring is fixedly connected to the connecting block. One end of the connecting block is fixedly connected to a limiting ball.

[0010] Preferably, a rod is slidably connected to the upper side of the disc, a first spring is sleeved on the outside of the rod and the inside of the disc, and a pull ring is fixedly connected to the upper end of the rod.

[0011] Preferably, the inner surface of the steering plate is provided with slots, and the disc is movably engaged with the steering plate by a rod, the rod being used in conjunction with the slots.

[0012] Preferably, there are two lower handles, the connecting sleeve is located between the two sets of lower handles, and there are two sets of telescopic blocks, which are slidably connected to the connecting sleeve.

[0013] Preferably, the connecting sleeve is fixedly connected to the telescopic rod, the telescopic rod is slidably connected to the telescopic block, and a second spring is provided on the inner side of the telescopic block.

[0014] Preferably, the limiting ball is located on both sides of the upper handle, the upper handle is movably engaged with the lower handle through the limiting ball, and the limiting hole is used in conjunction with the limiting ball.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The main bracket, adjusting bracket, lower handle, and upper handle are designed to facilitate the adjustment of the length of the lower and upper handles, as well as the angle between the lower handle and the main bracket. By pressing the limiting balls on both sides of the upper handle, the lower handle moves into the limiting holes on both sides. The limiting balls are then inserted into the limiting holes by the fourth spring on the rear side, thus fixing the upper handle in place. When the angle needs to be adjusted, the two sets of pull plates on the outside of the connecting sleeve between the lower handles are pressed, causing the telescopic block to slide within the telescopic rod. As the telescopic block slides, it causes the pull plate at the outer end and the limiting post on the lower side to disengage from the limiting groove in the adjusting bracket. At this time, the entire lower handle can rotate and be adjusted within the adjusting bracket. After adjustment, the pull plates are released, and the second spring on the outside of the telescopic rod and the third spring on the rear side of the pull plates re-insert the limiting post into the limiting groove in the adjusting bracket.

[0017] 2. The arrangement of the steering plate, slot, disc, bolt, main bracket, insert rod, first spring, and pull ring facilitates the adjustment of the left and right angles between the steering plate and the main bracket. By pulling the pull ring, the insert rod is disengaged from the slot outside the steering plate. Then, the angle between the main bracket and the steering plate is rotated. After adjusting to the appropriate angle, the pull ring is released, and the first spring outside the insert rod rebounds, allowing it to be reinserted into the slot inside the steering plate to complete the limiting and fixing.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6 A double-bar wheeled snowplow shown includes a pusher plate 1 for pushing snow;

[0029] Steering plate 2 is threadedly connected to the rear side of push plate 1. A circular plate 4 is movably sleeved on the upper side of steering plate 2. Bolts 5 are threaded through the interior of the circular plate 4. A main bracket 6 is fixedly connected to the lower side of the circular plate 4. The circular plate 4 is threadedly connected to the main bracket 6. Adjusting brackets 10 are fixedly connected to the rear sides of the main bracket 6. Limit grooves 11 are opened on the inner surface of the adjusting brackets 10. Tires 12 are rotatably connected to the sides of the main bracket 6.

[0030] The movable rod 13 is hinged inside the adjusting bracket 10 and is used to rotate the lower handle 14. The movable rod 13 is fixedly connected to the lower handle 14. A connecting sleeve 15 is fixedly connected to the inner side of the lower handle 14. A telescopic block 16 is slidably connected inside the connecting sleeve 15. A telescopic rod 17 is slidably connected inside the telescopic block 16. A second spring 18 is sleeved on the outside of the telescopic rod 17. A pull plate 19 is fixedly connected to the front side of the telescopic block 16. The pull plate 19 is slidably connected to the lower handle 14. A connecting plate 20 is fixedly connected to the outer end of the telescopic block 16. A third spring 21 is fixedly connected to both sides inside the connecting plate 20. A limit post 22 is fixedly connected to the lower outer side of the connecting plate 20.

[0031] Limiting holes 23 are provided on both sides above the lower handle 14 for adjusting the limit. An upper handle 24 is slidably connected inside the lower handle 14. A grip 25 is fixedly connected to the upper end of the upper handle 24. A fourth spring 26 is provided on both sides inside the upper handle 24. A connecting block 27 is fixedly connected to the outer end of the fourth spring 26. A limiting ball 28 is fixedly connected to one end of the connecting block 27. By pressing the limiting balls 28 on both sides of the upper handle 24, the upper handle 24 moves in the limiting holes 23 on both sides inside the lower handle 14. The limiting balls 28 are rebounded by the fourth spring 26 on the rear side and inserted into the limiting holes 23, thus limiting the upper handle 24. When the angle needs to be adjusted, press the two sets of pull plates 19 outside the connecting sleeve 15 between the lower handle 14, which will cause the telescopic block 16 to slide within the telescopic rod 17. When the telescopic block 16 slides, it will cause the pull plate 19 at the outer end and the limiting post 22 on the lower side to disengage from the limiting groove 11 in the adjusting bracket 10. At this time, the entire lower handle 14 can rotate and adjust within the adjusting bracket 10. After adjustment, release the pull plate 19. The second spring 18 outside the telescopic rod 17 and the third spring 21 on the back side of the pull plate 19 will rebound, and the limiting post 22 will be reinserted into the limiting groove 11 in the adjusting bracket 10.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a rod 7 is slidably connected to the upper side of the disc 4. A first spring 8 is sleeved on the outside of the rod 7 and the inside of the disc 4. A pull ring 9 is fixedly connected to the upper end of the rod 7. By pulling the pull ring 9, the rod 7 is driven to disengage from the slot 3 outside the steering plate 2. Then, the angle between the main bracket 6 and the steering plate 2 is rotated. After adjusting the appropriate angle, the pull ring 9 is released. The first spring 8 outside the rod 7 rebounds and is reinserted into the slot 3 inside the steering plate 2 to complete the limiting and fixing.

[0033] like Figure 2 and Figure 3 As shown, slots 3 are provided on one side of the inner surface of the steering plate 2. The disc 4 is movably engaged with the steering plate 2 by the insert rod 7. The insert rod 7 and the slot 3 are used in conjunction. The main bracket 6 and the disc 4 are threadedly connected. The main bracket 6, the disc 4 and the steering plate 2 are movable. When the pull ring 9 and the insert rod 7 are pulled, the insert rod 7 is disengaged from the slot 3 on the outside of the steering plate 2. In this way, the steering plate 2, the disc 4 and the main bracket 6 can be rotated and adjusted.

[0034] like Figure 1 and Figure 4As shown, there are two lower handles 14, and the connecting sleeve 15 is located between the two lower handles 14. There are two sets of telescopic blocks 16. The two sets of telescopic blocks 16 are slidably connected to the connecting sleeve 15. By pressing the two sets of pull plates 19 outside the connecting sleeve 15 between the lower handles 14, the telescopic blocks 16 are driven to slide within the telescopic rod 17. When the telescopic blocks 16 slide, the pull plates 19 at the outer end and the limiting post 22 on the lower side are disengaged from the limiting groove 11 in the adjusting bracket 10. At this time, the entire lower handle 14 can be rotated and adjusted within the adjusting bracket 10.

[0035] like Figure 4 As shown, the connecting sleeve 15 is fixedly connected to the telescopic rod 17, and the telescopic rod 17 is slidably connected to the telescopic block 16. The inner side of the telescopic block 16 is provided with a second spring 18. During the movement of the telescopic block 16 outside the telescopic rod 17, the stability of the movement of the telescopic block 16 is enhanced. The second spring 18 outside the telescopic rod 17 allows the pull plate 19 and the telescopic block 16 to rebound and push the pull plate 19 and the limiting post 22 into the adjusting bracket 10 for limiting.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, the limiting balls 28 are located on both sides of the upper handle 24. The upper handle 24 is movably engaged with the lower handle 14 through the limiting balls 28. The limiting holes 23 cooperate with the limiting balls 28. By pressing the limiting balls 28 on both sides of the upper handle 24, the upper handle 24 moves in the limiting holes 23 on both sides inside the lower handle 14. The limiting balls 28 are rebounded by the fourth spring 26 on the rear side and inserted into the limiting holes 23 to limit and fix the upper handle 24.

[0037] The working principle of this utility model is as follows: When shoveling snow from the top surface is required, the user holds the handle 25 at the top of the upper handle 24 and pushes the tires 12 on both sides and the push plate 1 on the front to shovel snow. Depending on the user's height and shoveling comfort, the user first presses the limiting balls 28 on both sides of the upper handle 24 to move them into the limiting holes 23 on both sides inside the lower handle 14. The limiting balls 28 are then inserted into the limiting holes 23 by the fourth spring 26 on the rear side, thus limiting and fixing the upper handle 24. Next, when it is necessary to adjust the tilt angle between the lower handle 14 and the upper handle 24, the user presses the two sets of pull plates 19 outside the connecting sleeve 15 between the lower handles 14, which causes the telescopic block 16 to slide within the telescopic rod 17. When the telescopic block 16 slides, it causes the outer pull plate 19 to move inside the lower handle 14. When the pull plate 19 moves, it causes the limiting post 22 on the lower side to disengage from the limiting groove 11 in the adjusting bracket 10. At this time, the entire lower handle 14 is adjusted. The bracket 10 is rotated for adjustment. After adjusting the tilt angle, the pull plate 19 is released. The second spring 18 outside the telescopic rod 17 rebounds and the third spring 21 behind the pull plate 19 rebounds, re-inserting the limiting post 22 into the limiting groove 11 inside the adjusting bracket 10, thus limiting and fixing the entire lower handle 14. Next, when it is necessary to adjust the left and right angle between the push plate 1 and the main bracket 6, the pull ring 9 on the upper side of the disc 4 is pulled to drive the insertion rod 7, causing the insertion rod 7 to disengage from the hole groove 3 outside the steering plate 2. Then, the angle between the entire main bracket 6, the disc 4, and the steering plate 2 is rotated. After adjusting to the appropriate angle, the pull ring 9 is released. The first spring 8 outside the insertion rod 7 rebounds and re-inserts into the hole groove 3 inside the steering plate 2 to complete the limiting and fixing. At this time, the user holds the handle 25 and continues to push the entire snowplow to clear snow from the ground. This completes the use of the double-bar wheeled snowplow.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
