Description

Technical Field

[0001] This utility model belongs to the field of curbstone construction technology, specifically relating to a portable prying tool for adjusting curbstones. Background Technology

[0002] In the process of municipal road construction, road maintenance, and landscape road construction, the installation and adjustment of curb stones is a crucial procedure, as the installation accuracy directly affects the overall aesthetics of the road, traffic safety, and drainage function.

[0003] Traditional crowbars have a simple structure, relying solely on the bar and a simple pry bar for leverage. When prying up curbs, it is necessary to find a suitable support point. If the support point is not chosen properly, it is not only difficult to effectively pry up the curb, but it is also easy to cause bumps and damage to the surface of the curb, resulting in material waste. Secondly, the adjustment of curbs requires a high degree of precision. Traditional tools can only achieve rough prying and cannot make fine adjustments to the position of the curb. Workers often need to try repeatedly, adjusting the position by striking with a hammer or using wedges, which is cumbersome and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a portable prying tool for adjusting curb stones, which can easily and quickly pry up curb stones with minimal effort, and can also make fine adjustments to curb stones.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A portable prying tool for adjusting curb stones includes a pry bar, one end of which is fixedly connected to a pry plate, the pry bar and the pry plate being set at an obtuse angle, the other end of which is fixedly connected to a handle, a cavity being formed inside the pry bar near the pry plate, a fine-tuning component being provided on the side wall of the pry bar located in the cavity, and a support component being provided on the side wall of the pry bar.

[0007] Furthermore, the fine-tuning component includes a screw sleeve rotatably connected to the side wall of the cavity, with pry bars passing through both ends of the screw sleeve, a screw rod internally threaded onto the screw sleeve, and a top plate rotatably connected to one end of the screw rod located on the upper side of the pry plate. A transmission component is provided on the side wall of the screw sleeve.

[0008] Furthermore, the top plate is rotatably connected to a number of ball bearings at the end near the pry plate.

[0009] Furthermore, the transmission assembly includes a first bevel gear fixedly connected to the side wall of the screw sleeve, a second bevel gear meshing with the side wall of the first bevel gear, a transmission shaft fixedly connected to the side wall of the second bevel gear, the other end of the transmission shaft passing through the crowbar and fixedly connected to a handwheel, and the transmission shaft being rotatably connected to the crowbar.

[0010] Furthermore, the handle includes two force-bearing rods, which are L-shaped and fixedly connected to the side wall of the crowbar near the end. Each force-bearing rod is fixedly connected to a rubber sleeve on its side wall.

[0011] Furthermore, the support assembly includes a support rod hinged to the side wall of the crowbar, and a support plate hinged to the other end of the support rod.

[0012] Furthermore, the crowbar has two flexible clips fixedly connected to its side wall, and the flexible clips are adapted to the support rod.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a portable prying tool for adjusting curb stones. Through the cooperation of pry bar, pry plate, support component and fine adjustment component, the support rod and support plate in the support component can stably form a force support point. There is no need to find external support. A single person can easily pry up the curb stone. Compared with the traditional tool that requires multiple people to work together, it greatly reduces the manpower requirement. Moreover, the operator only needs to turn the handwheel to make fine adjustment of the curb stone position. There is no need to repeatedly knock or insert wedges, which greatly shortens the adjustment time. At the same time, the pry bar is easy to carry and has a small storage space.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-4 As shown, a portable prying tool for adjusting curb stones includes a pry bar 1, a pry plate 2 fixedly connected to one end of the pry bar 1, the pry bar 1 and the pry plate 2 being set at an obtuse angle, a handle fixedly connected to the other end of the pry bar 1, a cavity 6 being opened inside the pry bar 1 near the pry plate 2, a fine-tuning component being provided on the side wall of the pry bar 1 located in the cavity 6, and a support component being provided on the side wall of the pry bar 1.

[0023] like Figure 3 and Figure 4 As shown, the fine-tuning component includes a screw sleeve 7 rotatably connected to the side wall of the cavity 6. The two ends of the screw sleeve 7 pass through the pry bar 1. The screw sleeve 7 is internally threaded with a screw rod 8. The screw rod 8 is rotatably connected to a top plate 9 at one end on the upper side of the pry plate 2. A transmission component is provided on the side wall of the screw sleeve 7.

[0024] Several ball bearings 10 are rolled on one end of the top plate 9 near the pry bar 2.

[0025] Specifically, to prevent the screw sleeve 7 from driving the screw 8 to rotate synchronously, a limiting component can be set on the screw 8. The limiting component can be any one of a positioning rod, a slider groove, or an interference fit. Since the limiting structure is a mature existing technology, it is not shown in the attached drawings of this scheme. In addition, when the screw sleeve 7 rotates, the top plate 9 is displaced to the upper left by the screw 8. The ball bearings 10 on the top plate 9 use rolling friction instead of sliding friction during fine adjustment, which reduces the scratch damage to the bottom of the curbstone and reduces the damage rate of the curbstone caused by improper tool operation.

[0026] like Figure 4 As shown, the transmission assembly includes a first bevel gear 11 fixedly connected to the side wall of the screw sleeve 7, a second bevel gear 12 meshing with the side wall of the first bevel gear 11, and a transmission shaft 13 fixedly connected to the side wall of the second bevel gear 12. The other end of the transmission shaft 13 passes through the pry bar 1 and is fixedly connected to a handwheel 14. The transmission shaft 13 is rotatably connected to the pry bar 1. The handwheel 14 is positioned in the handle position so that the operator can use their other hand to rotate the handwheel 14 to control the displacement of the top plate 9 when applying force.

[0027] like Figure 1 and Figure 3 As shown, the handle includes two L-shaped force-bearing rods 4, which are fixedly connected to the side wall of the pry bar 1 near the end. Each force-bearing rod 4 has a rubber sleeve 5 fixedly connected to its side wall. The handle, composed of the L-shaped force-bearing rods 4 and the rubber sleeves 5, increases the friction between the hand and the handle, preventing slippage during operation. It also conforms to ergonomic design, reducing hand fatigue and further improving ease of operation.

[0028] like Figure 1As shown, the support assembly includes a support rod 15 hinged to the side wall of the crowbar 1, and a support plate 16 hinged to the other end of the support rod 15. Two flexible clips 3 are fixedly connected to the side wall of the crowbar 1, and the flexible clips 3 are adapted to the support rod 15.

[0029] By using the obtuse angle design of the crowbar 1 and the pry bar 2, the stress point at the bottom of the curb can be quickly found. With the support rod 15 and the support plate 16 in the support assembly, a stable stress support point can be formed. There is no need to find external support. A single person can easily pry up the curb. Compared with the traditional tool method that requires multiple people to work together, the manpower requirement is greatly reduced.

[0030] When the tool is not in use, the support rod 15 can be locked into the flexible buckle 3 for secure storage, preventing the support rod 15 from being lost or worn out during transport. The overall tool structure is compact and easy for staff to carry, making it particularly suitable for scenarios requiring frequent movement, such as municipal road maintenance, thus solving the problems of inconvenient storage and carrying of traditional tools.

[0031] The working principle of this utility model is as follows: First, insert the pry bar 2 into the bottom of the curbstone, then adjust the angle of the pry bar 1, and open the support rod 15 to a suitable angle so that the support plate 16 is in contact with the ground to form a support point. Then, press the handle to use the lever principle to lift the curbstone to a suitable height. Then, according to the adjustment requirements, turn the handwheel 14 to drive the transmission shaft 13 to rotate. The transmission shaft 13 drives the second bevel gear 12 to rotate. The second bevel gear 12 meshes with the first bevel gear 11 and drives the screw sleeve 7 to rotate. The screw sleeve 7 drives the screw rod 8 to extend. The screw rod 8 drives the top plate 9 to be in contact with the surface of the curbstone. Through the small displacement of the top plate 9, the curbstone is finely adjusted. After the adjustment is completed and the curbstone is pre-embedded, the pry bar 1 can be taken out to realize the prying operation of the curbstone.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
