Description

Technical Field

[0001] This utility model relates to the field of tool shovel technology, and in particular to a support mechanism and its labor-saving shovel. Background Technology

[0002] A shovel, also known as a spade, is a common tool for digging, lifting, or moving materials. It is suitable for loose materials such as sand, snow, and soil, and is widely used in construction, landscaping, and agriculture. For example, in winter when snow is accumulated and mechanical equipment cannot be used, workers typically use traditional hand shovels to clear the snow.

[0003] When shoveling snow, workers shovel the snow from the middle of the road to both sides, creating snow piles on either side. However, during this process, workers need to repeatedly bend over and swing the shovel, bearing the weight of both the snow piles and the shovel itself. This results in high labor intensity, fatigue, and even lumbar strain.

[0004] Therefore, it is necessary to design a support mechanism and its labor-saving shovel that can enable more thorough mixing of the materials while reducing the time required for thorough mixing, thereby improving mixing efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a support mechanism and its labor-saving shovel, which can provide support for the shovel during operation, thereby reducing the burden on the workers, reducing labor intensity, and improving work efficiency.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A support mechanism includes: a support body, rollers, and a connecting kit. One end of the support body is provided with a wheel frame, the rollers are rotatably mounted on the wheel frame, and the connecting kit is provided at the other end of the support body.

[0008] The main body of the support includes a main rod, a telescopic auxiliary rod, and an elastic element. The telescopic auxiliary rod slides and extends along the axial direction of the main rod. The elastic element is located between the main rod and the telescopic auxiliary rod and provides an elastic force that keeps them apart. The connecting kit is installed at the end of the main rod, and the wheel frame is installed at the end of the telescopic auxiliary rod. In use, the connecting kit is fixed to an external shovel, and the rollers on the wheel frame are pressed against the ground.

[0009] In one embodiment, the elastic element is a spring structure, and the elastic element is sleeved around the main rod and the telescopic auxiliary rod.

[0011] In one embodiment, the connecting kit includes a body and a top cover, the top cover being mounted to the body by positioning bolts, and a receiving cavity for connecting an external shovel is formed between the top cover and the body.

[0012] In one embodiment, the upper cover has multiple limiting holes and limiting pins. The limiting pins pass through the limiting holes and connect to the external shovel, thereby preventing the external shovel from rotating relative to the connecting kit.

[0013] In one embodiment, the connecting kit and the main rod are hinged together by a locking assembly;

[0014] The locking assembly includes: a first toothed disc disposed at the end of the main rod, a second toothed disc disposed on the connecting kit, and a limiting bolt.

[0031] This utility model provides a support mechanism 10, such as Figure 1 As shown, it includes: a support body 100, a roller 200 and a connecting kit 300. One end of the support body 100 is provided with a wheel frame 110, the roller 200 is rotatably mounted on the wheel frame 110, and the connecting kit 300 is provided at the other end of the support body 100.

[0032] Among them, such as Figure 2 As shown, the support body 100 includes a main rod 120, a telescopic auxiliary rod 130, and an elastic member 140. The telescopic auxiliary rod 130 slides and extends along the axis of the main rod 120. The elastic member 140 is located between the main rod 120 and the telescopic auxiliary rod 130 and provides an elastic force that keeps them apart. A connecting kit 300 is installed at the end of the main rod 120, and a wheel frame 110 is installed at the end of the telescopic auxiliary rod 130. In use, the connecting kit 300 is fixed to an external shovel, and the rollers 200 on the wheel frame 110 are pressed against the ground.

[0033] In this embodiment, the elastic element 140 is a spring structure, and the elastic element 140 is sleeved around the main rod 120 and the telescopic auxiliary rod 130. Positioning pieces 121 (e.g., ...) are provided on both the main rod 120 and the telescopic auxiliary rod 130. Figure 2 As shown, the two ends of the elastic element 140 abut against the two positioning plates 121 respectively. In use, the elastic element 140 provides elastic force to the support mechanism 10, thereby using its elastic force to throw the shoveled snow further. The specific working principle will be explained below.

[0034] In this embodiment, as Figure 3 As shown, the connecting kit 300 includes a main body 310 and a top cover 320. The top cover 320 is mounted on the main body 310 by positioning bolts, and a receiving cavity for connecting an external shovel is formed between the top cover 320 and the main body 310. In addition, the top cover 320 has multiple limiting holes 321 and limiting pins (not shown). In use, the limiting pins pass through the limiting holes 321 and connect with the external shovel, thereby preventing the external shovel from rotating relative to the connecting kit 300.

[0035] In another embodiment, such as Figure 4 and Figure 5As shown, the connecting kit 300 is provided with a first sleeve 301 and a second sleeve 302. The first sleeve 301 is sleeved and fitted with the main rod 120, and the second sleeve 302 is fitted and connected with the external shovel.

[0036] This utility model also discloses a labor-saving shovel 20, which includes the aforementioned support mechanism 10, such as... Figure 6 and Figure 7 As shown, it also includes a shovel bar 400 and a shovel head 500 disposed at the front end of the shovel bar 400. The shovel bar 400 cooperates with the connecting kit 300 of the support mechanism 10. The connecting kit 300 divides the shovel bar 400 into two parts, wherein the part connecting the shovel head 500 forms a first angle 401 with the main bar 120, and the shovel head 500 forms a second angle 501 with the ground.

[0037] The working principle of the support mechanism 10 and its labor-saving shovel 20 of this utility model will be explained below in conjunction with the above structure:

[0038] Taking snow shovel as an example, when using it, the staff first assembles the support mechanism 10 onto the shovel handle 400, and places the rollers 200 of the support mechanism 10 on the ground. The shovel handle 400 forms a seesaw-like structure with the support mechanism 10.

[0039] The overall operation can be divided into two steps: "shoveling" and "throwing". Specifically, the support mechanism 10 is erected on the ground by the rollers 200. When the worker applies a pushing force to the shovel handle 400, the shovel 20 can be moved forward as a whole. At this time, the shovel head 500 will be inserted into the snow pile. Then, it is pulled back to separate part of the snow on the shovel head 500 from the snow pile, thus completing the "shoveling" step.

[0040] Next, the worker quickly presses down on the shovel handle 400, causing it to sway around the roller 200 of the support mechanism 10, which in turn causes the shovel head 500 to tilt upwards. At this point, the snow is thrown out under centrifugal force, completing the "throwing" step. Thus, the labor-saving shovel 20 utilizes the lever principle to achieve labor-saving operation. The support mechanism 10 is supported on the ground, and the weight of both the snow and the shovel itself is borne by the support mechanism 10, greatly reducing the worker's burden. Secondly, the worker does not need to bend over during use, which better protects the worker's lumbar spine and reduces strain.

[0041] It should be noted that the elastic element 140 of the support mechanism 10 plays a crucial role in its operation, making the "throwing" process easier and allowing the snow to be thrown further. Specifically, when throwing snow, the worker quickly presses down on the shovel handle 400, causing the labor-saving shovel 20 to sway around the roller 200 as a fulcrum. During this process, some of the pressure compresses the elastic element 140. Then, at the moment the worker stops applying force, the elastic potential energy accumulated in the elastic element 140 is rapidly released, causing the labor-saving shovel 20 to tend to jump upwards. In this way, the shovel head 500 can provide greater centrifugal force to the snow, allowing it to be thrown further and making it easier for workers to remove the snow to the sides of the road.

[0042] It is worth emphasizing that by changing the connection position of the connecting kit 300 on the shovel 400, the size of the second included angle 501 can be changed, that is, the tilt of the shovel 400 can be changed, thereby adjusting the angle of snow shoveling; at the same time, as the tilt of the shovel 400 changes, the height of the end of the shovel 400 will also change, thus adapting to workers of different heights.

[0043] Furthermore, setting the connecting kit 300 and the main pole 120 in a hinged relationship can also accommodate workers of different heights and make the snow-shoveling angle (second included angle 501) adjustable. Specifically, in some embodiments, the connecting kit 300 and the main pole 120 are hinged through a locking assembly 330. Figure 2 and Figure 3 As shown, the locking assembly 330 includes: a first gear 331 disposed at the end of the main rod 120, a second gear 332 disposed on the connecting kit 300, and a limiting bolt 333. The second gear 332 is adapted to the first gear 331. The locking assembly 330 adjusts the angle between the connecting kit 300 and the main rod 120 by tightening or loosening the limiting bolt 333.

[0044] In this embodiment, as Figure 2 and Figure 5 As shown, the wheel frame 110 is equipped with two rollers 200, which are located on both sides of the telescopic auxiliary rod 130. The design of the two rollers 200 can increase the support area of ​​the support mechanism 10 on the ground, thereby forming a three-point support with the shovel head 500, so that the labor-saving shovel 20 can stand upright on the ground and is not easy to tip over.

[0045] In some embodiments, the end of the shovel 400 is provided with a gripping crossbar 410 (e.g. Figure 7 As shown), the grip bar 410 is designed for easy gripping by the staff, allowing them to perform push, pull, and press operations more easily.

[0046] In some embodiments, the shovel head 400 and the shovel handle 500 are detachably connected via a snap-fit ​​or plug-in structure (not shown). This allows for the installation of various types and styles of shovel heads 400, enabling convenient replacement of the shovel head 400 to meet different work requirements.

[0047] In summary, the support mechanism 10 and its labor-saving shovel 20 of this utility model can reduce the burden on workers during operation, thereby reducing the labor intensity of workers and improving work efficiency.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
