Description

Technical Field

[0001] This utility model belongs to the field of snow guide plate adjustment, specifically relating to an angle adjustment mechanism for snow guide plates and a snow sweeper. Background Technology

[0002] In winter road maintenance operations, snow deflectors are key functional components of snow removal equipment (such as snowplows, snowplows, snowplows, etc.). They are mainly used to guide snow that is blown or blown out during the operation to the side of the road or a designated area, so as to prevent snow from accumulating on the driving lane, sidewalk or near key facilities, thereby ensuring smooth traffic and public safety.

[0003] Traditional snow deflectors are mostly fixed installation structures, which cannot flexibly adjust the snow guiding direction according to actual operation needs. Although some adjustable snow deflectors have angle adjustment functions, they usually use bolt fastening or manual locking methods, which have problems such as inconvenient adjustment, cumbersome operation, and unreliable locking. The whole operation process is time-consuming and labor-intensive, and cannot achieve rapid response, which seriously affects the efficiency of operation and the flexibility of adjustment. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a snow guide angle adjustment mechanism and snow sweeper that is simple in structure, has good stability, and allows for quick one-handed adjustment of the snow guide angle.

[0005] The objective of this utility model can be achieved by addressing the following technical problem: proposing an angle adjustment mechanism for a snow guide plate, comprising: a housing, the interior of which is provided with an installation cavity;

[0006] Several snow guides are movably disposed at the bottom of the housing, and the snow guides are connected to each other by connecting plates, which are movably disposed within the mounting cavity.

[0007] An adjusting member is movably disposed within the mounting cavity and extends outside the housing. The inner wall of the mounting cavity forms a locking area. One end of the adjusting member is movably inserted into the locking area, and the other end is movably sleeved on the connecting plate.

[0008] An elastic element, one end of which is connected to the adjusting element and the other end of which is pressed against the top wall of the mounting cavity, can lock the adjusting element into the locking area due to its elastic deformation, thereby restricting the rotation of the snow guide plate;

[0009] When the adjusting member is raised, it can disengage from the locking area, and when rotated, it drives the connecting plate to adjust the angle of the snow guide plate.

[0010] In the above-mentioned angle adjustment mechanism for snow guides, each snow guide is provided with a connecting post located at its rotation center circumference. The connecting post has a through hole, and the connecting post moves through the housing and extends into the mounting cavity so that the fastener in the through hole can be connected to the connecting post.

[0011] In the above-mentioned angle adjustment mechanism for snow guides, an arc-shaped guide groove is provided on the housing, and the connecting column is movably disposed within the arc-shaped guide groove.

[0012] In the above-mentioned angle adjustment mechanism for a snow guide, the adjustment element includes:

[0013] A lifting block is vertically disposed within the mounting cavity, with the top end of the lifting block extending outside the housing;

[0014] An anti-detachment block is connected to any one of the snow guide plates, and a stepped groove is provided in the anti-detachment block. The stepped groove can be aligned and connected with the through hole when the anti-detachment block is locked into the connecting plate, so that the fastener can abut against the inner wall of the stepped groove and be connected in the through hole.

[0015] The traction block is integrally formed with the lifting block. One end of the traction block is connected to a stop block, which is movably inserted into the locking area. The other end of the traction block forms a traction part, which is movably sleeved on the anti-detachment block.

[0016] In the above-mentioned angle adjustment mechanism for snow guides, the lifting block includes a main body and a lifting part. The main body is integrally formed with the traction block. The elastic element is sleeved on the main body, and the main body is provided with an anti-misalignment block and a locking hole. The lifting part is provided with an installation groove and an anti-misalignment groove. When the installation groove is sleeved on the main body, the anti-misalignment block can be inserted into the anti-disengagement groove, so that the locking hole can be connected by a screw to restrict the movement of the lifting part relative to the main body.

[0017] In the above-mentioned angle adjustment mechanism for snow guides, a guide groove is formed between the main body and the traction block, and the elastic element is connected to the bottom wall of the guide groove.

[0018] In the above-mentioned angle adjustment mechanism for snow guides, the locking area has arc-shaped partition blocks and limiting blocks, an engagement groove is formed between two adjacent partition blocks, and each partition block is equipped with a limiting block, forming a stop groove with the limiting block. The stop block is movably inserted into the engagement groove or the stop groove.

[0019] In the above-mentioned angle adjustment mechanism for snow guides, a limiting ring is also formed on the housing, and a guide block extends from the bottom wall of the main body to form a guide block, which is movably inserted into the limiting ring.

[0020] In the above-mentioned angle adjustment mechanism for snow guides, the housing includes a mounting frame and a cover. The snow guides are movably connected to the bottom wall of the mounting frame. The cover is detachably connected to the mounting frame and forms the mounting cavity therewith. A positioning hole is provided on the cover. An operating handle is formed at the top of the lifting part. The lifting part passes through the positioning hole, so that the operating handle is exposed outside the cover.

[0021] The technical solution adopted by this utility model to solve its technical problem is to also propose a snow sweeper, including one of the above-mentioned angle adjustment mechanisms for snow guide plates.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The present invention provides an angle adjustment mechanism for a snow guide plate and a snow sweeper. The adjustment component can be lifted to disengage from the locking zone, so that the snow guide plate can be adjusted by linkage with the connecting plate during rotation. The overall structure is simple, improving adjustment efficiency and ease of operation. At the same time, with the elastic reset function of the elastic component, the adjustment component automatically engages with the locking zone of the inner wall of the machine housing when there is no external force, forming a stable mechanical limit. This effectively prevents the snow guide plate from shifting its angle due to vibration or wind during use, ensuring the stability and reliability of the snow guiding direction.

[0024] (2) The arc-shaped guide groove provides precise guidance for the movement of the connecting column, restricting it to move only along the preset arc, ensuring the accuracy and consistency of the snow guide plate rotation trajectory, and also preventing the connecting column from radially deviating or getting stuck during rotation, thus improving the smoothness of adjustment.

[0025] (3) The arc-shaped locking groove and stop groove correspond to multiple preset snow guiding angles, achieving precise positioning in multiple positions. The overall locking structure does not require additional springs or steel balls, making it simple, convenient, and reliable in locking, meeting the needs of different operating scenarios.

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0038] like Figure 1 As shown, this solution mainly describes in detail an angle adjustment mechanism for snow guide plate 2 used on a snowplow. However, this angle adjustment mechanism for snow guide plate 2 is not limited to the use in snowplows, but can also be applied to places where angle adjustment is required, such as the air guide plate structure in an air conditioner.

[0039] like Figures 1 to 5 As shown, an angle adjustment mechanism for snow guides 2 includes a housing 1, several snow guides 2, an adjusting member 3, and an elastic member 5.

[0040] The casing 1 has an internal mounting cavity 120. Several snow guides 2 are movably disposed at the bottom of the casing 1 and connected by a connecting plate 20, which is movably disposed within the mounting cavity 120. An adjusting member 3 is movably disposed within the mounting cavity 120 and extends outside the casing 1. The inner wall of the mounting cavity 120 forms a locking area 4. One end of the adjusting member 3 is movably inserted into the locking area 4, and the other end is movably sleeved on the connecting plate 20. One end of an elastic member 5 is connected to the adjusting member 3, and the other end is pressed against the top wall of the mounting cavity 120. The elastic member 5 can use its elastic deformation to lock the adjusting member 3 into the locking area 4 to restrict the rotation of the snow guides 2. When the adjusting member 3 is raised, it can disengage outside the locking area 4 and, when rotating, drive the connecting plate 20 to adjust the angle of the snow guides 2.

[0041] In the normal use state of the snow guide plate 2, in this embodiment, the adjusting member 3 is tightened in the locking area 4 by the elastic member 5, so as to ensure that the snow guide plate 2 is not affected by the reaction force of snow accumulation, equipment vibration or wind load impact during snow sweeping, thus improving the stability during operation. When the operator lifts the handle of the adjusting component 3 exposed outside the housing 1, overcoming the elastic force of the elastic element 5, the adjusting component 3 moves upward to disengage from the locking zone 4. It should be noted that the adjusting component 3 remains connected to the connecting plate 20 during lifting, and the two will not disengage. Therefore, once the locking zone 4 releases the rotational constraint on the adjusting component 3, the operator can rotate the adjusting component 3 to move the connecting plate 20 relative to the housing 1, thereby causing several snow guides 2 to swing around their rotation center relative to the housing 1 in the same direction, ultimately completing the angle adjustment of several snow guides 2. When the snow guides 2 reach the target angle, the operator can release the handle, and under the restoring force of the elastic element 5, the adjusting component 3 re-embeds into the new position of the locking zone 4, completing the angle positioning and locking. Therefore, this structure, by setting up an adjustable component 3 that can be lifted and rotated, works in conjunction with the connecting plate 20 to link multiple snow guide plates 2. Users only need to operate the adjustable component 3 to simultaneously adjust the tilt angle of all snow guide plates 2. The overall structure is simple, improving adjustment efficiency and ease of operation. At the same time, with the elastic reset effect of the elastic component 5, the adjustable component 3 automatically engages with the locking area 4 on the inner wall of the housing 1 when there is no external force, forming a stable mechanical limit. This effectively prevents the snow guide plates 2 from shifting in angle due to vibration or wind during use, ensuring the stability and reliability of the snow guiding direction.

[0042] Each snow guide plate 2 is provided with a connecting post 21 located at its rotation center circumference. A through hole 200 is provided on the connecting plate 20. The connecting post 21 moves through the housing 1 and extends into the mounting cavity 120 so that the fastener 201 in the through hole 200 can be connected to the connecting post 21.

[0043] like Figures 1 to 3As shown, in this embodiment, the rotation center of the connecting column 21 and the rotation center of the snow guide plate 2 are on the same straight line. That is to say, when the adjusting component 3 drives the connecting plate 20 to move, the connecting column 21 and the connecting plate 20 can be used to drive several snow guide plates 2 to adjust their angles synchronously. In this embodiment, three snow guide plates 2 are used, and each has the same installation structure to facilitate subsequent maintenance and replacement. Specifically, relying on the through holes 200 opened on the connecting plate 20, the connecting column 21 and the connecting plate 20 are fixedly connected by fasteners 201 (which can be screws or other components), so that multiple snow guide plates 2 can be linked synchronously, ensuring the consistency and stability of angle adjustment. This connection method has a simple structure and is easy to assemble. At the same time, using the connecting column 21 as the driving source for the snow guide plate 2 to adjust its angle around its rotation center improves the rotation accuracy and force uniformity, and extends the service life.

[0044] Furthermore, such as Figure 3 and Figure 4 As shown, this embodiment also provides an arc-shaped guide groove 100 on the housing 1, and the connecting post 21 of the snow guide plate 2 is movably disposed within this groove. This allows for precise guidance and limitation of the rotation trajectory of the snow guide plate 2, preventing it from shifting or jamming during adjustment. Therefore, the arc-shaped guide groove 100 not only enhances the structural guidance but also improves the rigidity and stability of the overall structure, ensuring that the snow guide plate 2 maintains good positioning at different angles, thus improving the accuracy and safety of snow sweeping direction control.

[0045] The adjusting component 3 includes: a lifting block 30, which is vertically disposed in the mounting cavity 120, with the top end of the lifting block 30 extending outside the housing 1; an anti-detachment block 31, which is connected to any snow guide plate 2, and has a stepped groove 310 inside the anti-detachment block 31. The stepped groove 310 can be aligned and connected to the through hole 200 when the anti-detachment block 31 is locked into the connecting plate 20, so that the fastener 201 can be pressed against the inner wall of the stepped groove 310 and connected to the through hole 200; and a traction block 32, which is integrally formed with the lifting block 30. One end of the traction block 32 is connected to a stop block 320, which is movably inserted into the locking area 4. The other end of the traction block 32 forms a traction part, which is movably sleeved on the anti-detachment block 31.

[0046] like Figure 2 , Figure 3 as well as Figure 5As shown, during the assembly process, the worker can pre-assemble the anti-detachment block 31 onto any corresponding connecting post 21 on the connecting plate 20. Specifically, as the anti-detachment block 31 is inserted into the connecting plate 20, it can be pressed against the inner stepped surface of the stepped groove 310 by the fastener 201 (screw or screw) and connected to the through hole 200 (preferably a threaded hole), thereby fixing the anti-detachment block 31 onto the connecting plate 20 and enhancing the reliability of the connection. As the traction block 32 is movably fitted onto the anti-detachment block 31, a horizontal force is applied to the anti-detachment block 31 via the traction block 32 when the lifting block 30 rotates. This allows the connecting plate 20 to drive the connecting column 21 to slide along the arc-shaped guide groove 100, ultimately adjusting the angle of the snow guide plate 2. When the lifting block 30 is raised, relative sliding occurs between the traction block 32 and the anti-detachment block 31 (but they do not disengage). At this time, the elastic element 5 is gradually compressed until the stop block 320 disengages outside the locking area 4, after which the lifting block 30 can be rotated. After the angle of the snow guide plate 2 is adjusted, the stop block 320 automatically engages with the locking area 4 under the action of the elastic element 5, automatically locking the lifting block 30 again. This structure achieves an integrated operation of "lifting—rotating adjustment—releasing—self-locking" without the need for additional tools, greatly improving operational convenience and safety.

[0047] The lifting block 30 includes a main body 300 and a lifting part 301. The main body 300 is integrally formed with the traction block 32. The elastic element 5 is sleeved on the main body 300. The main body 300 is provided with an anti-misalignment block 300a and a locking hole 300b. The lifting part 301 is provided with an installation groove 301a and an anti-misalignment groove 301b. When the installation groove 301a is sleeved on the main body 300, the anti-misalignment block 300a can be inserted into the anti-disengagement groove, so that the screw can be connected to the locking hole 300b to restrict the movement of the lifting part 301 relative to the main body 300.

[0048] like Figure 5 As shown, since the lifting block 30 needs to extend from the mounting cavity 120 to the outside of the housing 1, a split structure design is adopted. On the one hand, it is convenient for processing and molding, and on the other hand, it helps to improve the convenience of installation operation. Specifically, in this embodiment, the anti-misassembly design is achieved by the cooperation of the anti-misassembly block 300a and the anti-misassembly groove 301b to ensure the correct assembly direction and avoid functional failure due to assembly errors. At the same time, the locking hole 300b and the screw can firmly fix the lifting part 301 and the main body 300, preventing loosening and falling off during use, improving the reliability of the structure during use, and facilitating timely disassembly and replacement when a certain part is damaged, reducing maintenance costs and extending service life.

[0049] like Figure 2 and Figure 3As shown, in this embodiment, a guide groove 321 is formed between the main body 300 and the traction block 32, and the elastic member 5 is connected to the bottom wall of the guide groove 321. The lifting part 301 drives the main body 300 along... Figure 2 When lifted vertically upwards, the elastic element 5 is gradually compressed by the pressure of the inner wall of the housing 1. At the same time, when the lifting part 301 is not subjected to external force, the stop block 320 can be re-locked into the locking area 4 by the reset of the elastic element 5. Therefore, the guide groove 321 can effectively guide the compression and rebound process of the elastic element 5, prevent it from deviating, twisting or failing, improve the stability and life of the elastic element 5, and ensure that the adjusting part 3 can accurately reset and lock into the locking area 4 after each release, thus ensuring the long-term reliable operation of the locking function.

[0050] A limiting ring 101 is also formed on the housing 1, and a guide block 300c extends from the bottom wall of the main body 300, and the guide block 300c is movably inserted into the limiting ring 101.

[0051] like Figure 2 As shown, this embodiment provides a limiting ring 101 on the housing 1 and extends a guide block 300c at the bottom of the main body 300, so that the guide block 300c is movably inserted into the limiting ring 101. This provides precise guidance and lateral limitation for the up-and-down movement of the lifting part 301 and the main body 300, preventing it from shaking or tilting during lifting or resetting. This significantly improves the linearity and stability of the movement of the adjusting part 3, avoids jamming or wear due to eccentric force, and ensures the long-term stable operation of the entire adjusting mechanism.

[0052] The locking area 4 has arc-shaped partition blocks 40 and limit blocks 41. There is a locking groove 400 between two adjacent partition blocks 40, and each partition block 40 is equipped with a limit block 41, which forms a stop groove 410 with the limit block 41. The stop block 320 is movably inserted into the locking groove 400 or the stop groove 410.

[0053] like Figure 4 As shown, in this embodiment, the locking area 4 is provided with arc-shaped partition blocks 40 and limiting blocks 41 (the center of the arc is the rotation center of the lifting part 301, which is also the rotation center of the snow guide plate 2), forming multiple engaging grooves 400 and stopping grooves 410, so that the stopping block 320 can be engaged at different positions to realize multi-level angle adjustment of the snow guide plate 2; each engaging position has a clear positioning feel and stability, and the user can judge whether it is in place by feel. This structure realizes the precise positioning of the stopping block 320, improving the user experience and operation accuracy.

[0054] The housing 1 includes a mounting frame 10 and a cover 11. The snow guides 2 are movably connected to the bottom wall of the mounting frame 10. The cover 11 is detachably connected to the mounting frame 10 and forms a mounting cavity 120 with it. A positioning hole 110 is provided on the cover 11. An operating handle 301c is formed at the top of the lifting part 301. The lifting part 301 passes through the positioning hole 110, so that the operating handle 301c is exposed outside the cover 11.

[0055] like Figure 1 and Figure 2 As shown, in this embodiment, the housing 1 is designed as a split structure consisting of a mounting frame 10 and a detachable cover 11 (disassembly and assembly are achieved with screws or bolts), which facilitates the installation, inspection, and replacement of internal components and improves maintenance convenience. Furthermore, the positioning hole 110 on the cover 11 cooperates with the lifting part 301, allowing the operating handle 301c to be exposed outside the cover 11 for direct user operation; simultaneously, the cover 11 provides dustproof, waterproof, and snowproof protection for the internal structure, enhancing the overall durability and reliability of the mechanism in harsh environments.
