Description

Technical Field

[0001] This utility model relates to the field of snowplow technology, specifically a multi-segment adjustable angle snowplow. Background Technology

[0002] A snow shovel is a tool used to clear snow from sidewalks, driveways, parking lots, and other surfaces. Its design is typically very simple yet powerful. Snow shovels are mainly divided into two types: manual and electric. Manual snow shovels are the most common type, consisting primarily of a metal blade and a handle. Users repeatedly push the blade into the snow and forcefully knock or dump the snow off. Manual snow shovels are easy to operate and suitable for small areas or occasional use. Electric snow shovels, on the other hand, are more modern snow removal tools developed in recent years. They are equipped with an electric motor that rotates a metal or plastic blade, scraping up and throwing the snow to one side or behind. Electric snow shovels are suitable for larger areas, deeper snow accumulations, or situations requiring rapid clearing. They are convenient to operate, but relatively more expensive.

[0003] Common manual snow shovels, due to their simple structure, can generally only maintain a fixed angle, which is inconvenient in actual use. Especially when shoveling snow of different slopes and thicknesses, the fixed shovel angle forces users to repeatedly adjust the shoveling position, increasing the labor burden. In addition, when cleaning different surfaces such as the ground and roof, the inability to adjust the shovel angle reduces snow removal efficiency and affects the overall effect of snow removal work.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a multi-segment adjustable angle snowplow. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a multi-segment adjustable angle snowplow solution. First, the angle of the snowplow can be flexibly adjusted through the engagement of the triangular slot and the triangular block, adapting to different scenarios such as ground, roof, and steps without frequent body movement, thus reducing labor burden. Second, the diamond-shaped protrusions reduce snow adhesion, and the adjustable angle ensures that the snowplow maintains optimal contact with the snow surface, reducing the time spent cleaning the snowplow surface during operation. At the same time, the quick unlocking / locking mechanism shortens the time spent adjusting the angle, improving overall snow removal efficiency. Finally, the three-point support structure formed by the auxiliary plate and the connecting plate b prevents the snowplow from shaking during angle adjustment, and the locking design of the screw prevents the push plate from accidentally rotating during operation, improving safety.

[0006] This utility model provides the following technical solution: a multi-segment adjustable angle snowplow, comprising a stick and a shovel body;

[0007] A connecting plate is fixedly connected to one end of the rod, and two sets of symmetrically distributed adjustment components are provided at one end of the connecting plate.

[0008] Each of the adjustment components includes a locking plate a fixedly connected to the connecting plate and a locking plate b slidably connected to the connecting plate, wherein the opposite surfaces of the locking plate a and the locking plate b are provided with triangular slots;

[0009] The locking plate b is elastically connected to the connecting plate via a return spring. A rotatable connecting structure is provided between the locking plate a and the locking plate b. The surface of the connecting structure is provided with a pressing structure. The pressing structure is used to drive the locking plate b to slide along the sliding groove and compress the return spring.

[0011] As a preferred embodiment of the present invention, the extrusion structure includes two eccentric wheels rotatably connected to the surface of a pin shaft, and a push plate is connected to the surface of the two eccentric wheels.

[0012] As a preferred technical solution of this utility model, the inner cavity of the push plate is threaded with a screw rod, one end of which extends into the interior of the locking plate a, and the other end is fixedly connected to a knob.

[0013] As a preferred embodiment of this utility model, two auxiliary plates are fixedly connected to the middle of one end of the connecting plate, and the inner cavities of the two auxiliary plates are rotatably connected to the connecting plate b via a connecting shaft.

[0014] As a preferred technical solution of this utility model, the free ends of the connecting plate b and the connecting plate a are fixedly connected to the shovel body to form a three-point support structure, and the snow-facing surface of the shovel body is provided with multiple diamond-shaped protrusions.

[0015] As a preferred embodiment of this utility model, the rod body is T-shaped, and the surface of the rod body is fitted with a foamed rubber sleeve.

[0016] As a preferred technical solution of this utility model, the surface of the knob is provided with anti-slip texture, the anti-slip texture is a concave structure, and the surface of the foamed rubber sleeve is provided with fingerprint-like anti-slip texture.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model allows for flexible adjustment of the shovel angle through the meshing and adjustment of the triangular slot and triangular block. It can adapt to different scenarios such as ground, roof, and steps without the need for frequent body movement, thus reducing the burden of labor.

[0019] 2. This device reduces snow adhesion through diamond-shaped protrusions, and the adjustable angle ensures that the shovel body always maintains optimal contact with the snow surface, reducing the time spent cleaning the shovel surface midway; at the same time, the quick unlock / lock mechanism shortens the time spent adjusting the angle, improving the overall snow removal efficiency.

[0020] 3. The three-point support structure formed by the auxiliary plate and the connecting plate b of this utility model avoids the shovel body from shaking when adjusting the angle. At the same time, the locking design of the screw can prevent the push plate from rotating unexpectedly during operation, thus improving the safety of use. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 As shown, a multi-segment adjustable angle snowplow includes a rod body 1 and a shovel body 101.

[0030] One end of the rod body 1 is fixedly connected to a connecting plate 2, and one end of the connecting plate 2 is provided with two sets of symmetrically distributed adjustment components;

[0031] Each adjustment component includes a locking plate a3 fixedly connected to the connecting plate 2 and a locking plate b302 slidably connected to the connecting plate 2. The opposing surfaces of the locking plate a3 and the locking plate b302 are provided with triangular slots 303.

[0032] Locking plate b302 is elastically connected to connecting plate 2 via return spring 304. A rotatable connection structure is provided between locking plate a3 and locking plate b302. The surface of the connection structure is provided with a pressing structure. The pressing structure is used to drive locking plate b302 to slide along sliding groove 301 and compress return spring 304.

[0033] The connection structure includes a connecting plate a401 that is rotatably connected between the locking plate a3 and the locking plate b302 via a pin 4. Both sides of the connecting plate a401 are fixedly connected with triangular blocks 402 that are adapted to the triangular slot 303.

[0034] The extrusion structure includes two eccentric wheels 5 rotatably connected to the surface of the pin 4, and a push plate 501 is connected to the surface of the two eccentric wheels 5.

[0035] The inner cavity of the push plate 501 is threaded with a screw 6. One end of the screw 6 extends into the interior of the locking plate a3, and the other end is fixedly connected to a knob 601.

[0036] Two auxiliary plates 7 are fixedly connected to the middle of one end of the connecting plate 2, and the inner cavity of the two auxiliary plates 7 is rotatably connected to the connecting plate b702 through the connecting shaft 701;

[0037] The free ends of connecting plate b702 and connecting plate a401 are fixedly connected to the shovel body 101 to form a three-point support structure. The snow-facing surface of the shovel body 101 is provided with multiple diamond-shaped protrusions 8.

[0038] The shape of the rod body 1 is T-shaped, and the surface of the rod body 1 is fitted with a foamed rubber sleeve 9;

[0039] The surface of the knob 601 is provided with anti-slip texture, which is a concave structure, and the surface of the foamed rubber sleeve 9 is provided with fingerprint-like anti-slip texture.

[0040] This multi-stage adjustable angle snowplow allows for flexible adjustment of the 101-degree angle of the shovel body through an adjustment component. Combined with auxiliary support structures and functional components, it enhances snow removal efficiency. The specific working principle is as follows:

[0041] Structural basis: The rod body 1 serves as the gripping and force transmission component, and is connected to two sets of symmetrical adjustment components through the connecting plate 2. The auxiliary plate 7 and the connecting plate b702 form a three-point support structure, which enhances the stability of the connection between the shovel body 101 and the adjustment components.

[0042] Angle adjustment mechanism:

[0043] Unlocking process: Rotating knob 601 drives screw 6 to rotate, causing screw 6 to disengage from the inside of locking plate a3, unlocking push plate 501. Then push push plate 501 to move, causing eccentric wheel 5 to rotate around pin 4, no longer pressing on the surface of locking plate a3. At this time, reset spring 304 resets, causing locking plate b302 to slide along sliding groove 301. At this time, the triangular slots 303 on locking plate a3 and locking plate b302 disengage from the triangular blocks 402 on both sides of connecting plate a401, releasing the angle lock.

[0044] Angle adjustment: After unlocking, the connecting plate a401 can rotate around the pin 4, driving the shovel body 101 to adjust the angle synchronously. The connecting plate b702 rotates with the shovel body and rotates in the auxiliary plate 7 through the connecting shaft 701 to ensure structural stability during the adjustment process.

[0045] Locking and fixing: After adjusting to the target angle, rotate the push plate 501, so that the push plate 501 drives the eccentric wheel 5 to rotate, so that the eccentric wheel 5 presses against the surface of the locking plate a3, and at the same time drives the pin 4 to move. At this time, the pin 4 will pull the locking plate b302 to move, so that the triangular block 402 re-engages into the triangular slot 303 of the corresponding angle, thus completing the angle fixing. After the angle fixing is completed, rotate the knob 601 to drive the screw 6 to rotate, so that one end of the screw 6 is connected to the inside of the locking plate a3, limiting the position of the push plate 501 and preventing the push plate 501 from rotating back.

[0046] Accessibility features implemented:

[0047] The diamond-shaped protrusions 8 on the snow-facing surface of the shovel body 101 reduce the contact area between the snow and the shovel surface, thus reducing adhesion.

[0048] The T-shaped structure of the stick body 1, combined with the fingerprint-like anti-slip texture of the foamed rubber sleeve 9 and the concave anti-slip texture of the knob 601, enhances grip stability and prevents slippage during operation.
