Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carts, in particular to a cart capable of preventing a slope from sliding down. Background Art
[0002] Carts are very commonly used tools in construction projects. Carts can transport some materials more labor-savingly. The structure of the cart is relatively simple. When the cart is loaded with heavy construction materials, it is often difficult to push. When going uphill, if the worker slips or the slope is too steep to push, the cart may slide down the slope and cause property damage and personal injury.
[0003] Some existing cart brake devices generally use friction to brake, thereby preventing the cart from sliding down a slope. However, when the cart is loaded with heavy building materials, friction alone may not be able to effectively stop the cart, which may easily cause an accident.
[0004] In view of the above problems, an innovative design is carried out on the basis of the original cart. Utility Model Content
[0005] The utility model aims to provide a cart which can prevent sliding down a slope, so as to solve at least one technical problem raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cart for preventing sliding down a slope, comprising: a body, a mounting frame is provided at the bottom of the body, a wheel axle is installed on the inner side of the mounting frame, walking wheels are installed at both ends of the wheel axle, a locking groove is provided on the surface of the wheel axle, a latch is provided in the locking groove, a support rod is fixed on the surface of the latch, the latch is installed on the mounting frame, a guide groove is provided inside the mounting frame, the support rod is located in the guide groove, a return spring is installed on the surface of the support rod, the return spring is located in the guide groove, a traction rope is installed at one end of the latch away from the wheel axle, a handle is installed on the body, a ring body is installed on the lower surface of the handle, and a pull ring is installed at one end of the traction rope passing through the ring body.
[0007] Preferably, the wheel axle is rotatably connected to the vehicle body via a mounting frame, and the mounting frame and the vehicle body are fixedly connected.
[0008] Preferably, the locking grooves are distributed at equal angles on the surface of the wheel axle, and the locking grooves are trapezoidal structures when cross-sectioned.
[0009] Preferably, one end of the latch is located in the locking groove, and the end of the latch located in the locking groove is an inclined structure.
[0010] Preferably, the support rod is slidably connected to the mounting frame via a guide groove, and the support rod forms a telescopic structure with the guide groove via a return spring.
[0011] Preferably, a fixed pulley is installed on the lower surface of the vehicle body, and the traction rope is wound around the outer side of the fixed pulley.
[0012] The utility model provides a cart for preventing slipping, which has the following beneficial effects:
[0013] When the vehicle body is on a slope and is about to slide, the return spring will push the support rod to slide in the guide groove, and the support rod will drive the pin to insert into the locking groove on the surface of the wheel axle, so that the travel wheel cannot rotate in the opposite direction through the wheel axle and slide down the slope. When the vehicle body needs to be pulled in the reverse direction normally, the traction rope is pulled through the pull ring to move, the traction rope will pull the pin to move, and the pin will slide and move through the support rod and the guide groove until the pin exits the locking groove, so that the vehicle body can be pulled normally for reverse movement.

[0026] See also Figure 1-Figure 4The utility model provides a technical solution: a cart for preventing sliding down a slope, comprising: a body 1, a mounting frame 2 is provided at the bottom of the body 1, a wheel axle 3 is installed on the inner side of the mounting frame 2, walking wheels 4 are installed at both ends of the wheel axle 3, a locking groove 5 is provided on the surface of the wheel axle 3, a latch 6 is provided in the locking groove 5, a support rod 7 is fixed on the surface of the latch 6, the latch 6 is installed on the mounting frame 2, a guide groove 8 is provided inside the mounting frame 2, the support rod 7 is located in the guide groove 8, a return spring 9 is installed on the surface of the support rod 7, the return spring 9 is located in the guide groove 8, a traction rope 10 is installed at the end of the latch 6 away from the wheel axle 3, a handle 12 is installed on the body 1, a ring body 13 is installed on the lower surface of the handle 12, and a pull ring 14 is installed at the end of the traction rope 10 passing through the ring body 13.
[0027] The wheel axle 3 in this example is rotatably connected to the vehicle body 1 via the mounting frame 2 , and the mounting frame 2 and the vehicle body 1 are fixedly connected to facilitate the rotational movement of the running wheel 4 and the wheel axle 3 under the vehicle body 1 .
[0028] The locking grooves 5 in this example are distributed at equal angles on the surface of the wheel axle 3 , and the locking grooves 5 are cross-sectionally viewed as a trapezoidal structure, which facilitates the subsequent coordination and operation of the locking grooves 5 with other components.
[0029] In this example, one end of the latch 6 is located in the locking groove 5, and the end of the latch 6 located in the locking groove 5 is an inclined structure. The latch 6 can be inserted into the locking groove 5 to lock the wheel axle 3. When the wheel axle 3 rotates along the inclined surface of the latch 6, the latch 6 can withdraw from the locking groove 5 to avoid preventing the wheel axle 3 from rotating normally.
[0030] The support rod 7 in this example is slidably connected to the mounting frame 2 via the guide groove 8. The support rod 7 forms a telescopic structure with the guide groove 8 via the return spring 9, which facilitates the return spring 9 to push the support rod 7 to slide and adjust in the guide groove 8, thereby facilitating the support rod 7 to drive the latch 6 to perform synchronous adjustment movement.
[0031] In this example, a fixed pulley 11 is installed on the lower surface of the vehicle body 1, and the traction rope 10 is wound around the outer side of the fixed pulley 11, which facilitates the smoothness of the movement of the traction rope 10 and also prevents the traction rope 10 from being dragged on the ground.
[0032] Working principle: According to Figure 1-Figure 4 As shown, first, the worker can hold the handle 12 and push the vehicle body 1 uphill normally. Figure 2As shown, at this time, the running wheel 4 can rotate counterclockwise in the mounting frame 2 through the wheel shaft 3, and the inclined latch 6 will be pushed out by the inner wall of the locking groove 5, so as not to affect the normal running of the running wheel 4. When the vehicle body 1 is on the slope and is about to slide, the return spring 9 will push the support rod 7 to slide in the guide groove 8, so that the support rod 7 drives the latch 6 to insert into the locking groove 5 to lock the wheel shaft 3. At this time, the wheel shaft 3 cannot rotate in the opposite direction and slide down the slope.
[0033] When the vehicle body 1 needs to be pulled backward normally on flat ground, it is only necessary to pull the traction rope 10 through the pull ring 14, and the traction rope 10 pulls the pin 6 to move in the opposite direction until the pin 6 is disconnected from the locking groove 5. At this time, the pin 6 no longer locks the wheel axle 3, so that the vehicle body 1 can be pulled backward normally.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
