Description

Technical Field

[0001] The utility model relates to the technical field of tool carts, in particular to a tool cart capable of preventing collision. Background Art

[0002] The tool cart is a movable tool cabinet, which is suitable for the safe and reasonable transportation of tools and accessories at the production site. It is also suitable for the fixed location management of tools, knives and parts at the production site, so that the workers' storage and retrieval of items can be truly timely, accurate, efficient and low-cost.

[0003] According to a tool cart with an anti-collision structure disclosed (publication number: CN220783908U), in the above application, when pushing the cart, hold the pressure plate on the surface of the handle, the pressure rod on the surface of the pressure plate moves under the support of spring 2, the push rod on the surface of the pressure rod is folded, and the slide plate is pushed to move on the surface of the slide rail, and the cross bar fixed on the surface of the slide plate can drive the rack to move on the surface of the gear, and the gear can drive the cylinder to rotate, and the cross plate can drive the card plate to rotate together with the round rod, and the through hole on the surface of the card plate forms a cross perpendicular angle with the cross block, so the cross block and the vertical rod cannot be moved out of the card plate, and the box door cannot be opened, so as to avoid the situation in which the box door is opened due to collision during transportation and the tools are scattered.

[0004] However, in actual use, the above-mentioned equipment only uses springs as anti-collision structures. When encountering a strong impact, the springs are difficult to slow down the tool cart to achieve the anti-collision effect. In addition, the tool cart only has anti-collision structures on both sides and cannot provide protection against front collisions. In view of this, we propose a collision-proof tool cart.

DETAILED DESCRIPTION

[0021] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a collision-proof tool cart, comprising a box body 1, a drawer 2 is penetrated and slidably connected to the outer wall of the box body 1, a steering wheel 3 is rotatably connected to the lower surface of the box body 1, a speed control wheel 4 is rotatably connected to the lower surface of the box body 1, a connecting shaft 5 is penetrated and fixedly connected to the axis of the speed control wheel 4, a sleeve shell 7 is fixedly connected to the lower surface of the box body 1, and a deceleration assembly 6 is arranged inside the box body 1, and the deceleration assembly 6 includes an extrusion rod 61, a collision shell 62, an inclined block 63, a pressure block 64, an inclined groove 65, a guide rail 66, a spring 67, a hinged rod 68, a clamping rod 69, a fixed shaft 610, a clamping plate 611, an arc groove 612, and a rubber sheet 613.

[0022] In one embodiment of the utility model, an extrusion rod 61 is penetrated and slidably connected to the outer wall of the box body 1, and one end of the extrusion rod 61 located outside the box body 1 is fixedly connected to a collision shell 62, and the other end of the extrusion rod 61 is fixedly connected to an inclined block 63, and the inclined outer wall of the inclined block 63 is slidably connected to a pressure block 64, an inclined groove 65 is opened on the outer wall of the pressure block 64, and a guide rail 66 is fixedly connected to the outer wall of the pressure block 64, a spring 67 is fixedly connected to the upper surface of the pressure block 64, and a hinged rod 68 is hinged to the lower surface of the pressure block 64, and the end of the hinged rod 68 away from the pressure block 64 is rotatably connected to a clamping rod 69, a fixed shaft 610 is penetrated and rotatably connected at the center of the planar outer wall of the clamping rod 69, and the end of the clamping rod 69 away from the hinged rod 68 is fixedly connected to a splint 611, an arc groove 612 is opened on the outer wall of the splint 611, and a rubber sheet 613 is fixedly connected to the inner wall of the arc groove 612.

[0023] In addition, both ends of the fixed shaft 610 are fixedly connected to the inner wall of the box body 1, and the end of the spring 67 away from the pressure block 64 is fixedly connected to the inner wall of the box body 1. When encountering a general collision, the spring 67 generates pressure on the pressure block 64, causing the pressure block 64 to generate an opposite thrust on the extrusion rod 61, thereby slowing down the tool cart to achieve an anti-collision effect.

[0024] In an embodiment of the utility model, the connecting shaft 5 passes through and is rotatably connected to the outer wall of the sleeve shell 7. The radius of the connecting shaft 5 is consistent with the radius of the arc groove 612. The center of the connecting shaft 5 is parallel to the center of the arc groove 612. When the clamping rod 69 rotates to squeeze the splint 611, the rubber sheet 613 on the splint 611 can press the connecting shaft 5, so that the deceleration effect of the speed control wheel 4 is better.

[0025] In an embodiment of the utility model, the collision shell 62 is composed of three collision plates, two of which are mirror-distributed at both ends of the other collision plate, and the three collision plates are all fixedly connected with an extrusion rod 61. The three collision plates can achieve an anti-collision effect in three directions of the box body 1, which can make the anti-collision range of the tool cart larger and improve the anti-collision ability of the tool cart.

[0026] In the embodiment of the utility model, a slide groove is opened on the inner wall of the box body 1, and the guide rail 66 is slidably connected to the inner wall of the slide groove. The slope of the inclined surface of the inclined groove 65 is consistent with the slope of the inclined surface of the inclined block 63, and the inclined block 63 is slidably connected to the inner wall of the inclined groove 65. When the extrusion rod 61 drives the inclined block 63 to move, the inclined block 63 slides in the inclined groove 65, so that the pressure block 64 rises along the slide groove. The rise of the pressure block 64 causes the hinge rod 68 to rise, driving the clamping rod 69 rotatably connected thereto to rotate, so that the clamping plate 611 clamps the connecting shaft 5, thereby slowing down the tool cart and achieving an anti-collision effect.

[0027] In the embodiment of the utility model, there are two sets of steering wheels 3, and the two sets of steering wheels 3 are mirror-distributed on the lower surface of the box body 1, and there are two sets of speed control wheels 4. The two sets of speed control wheels 4 are mirror-distributed on the lower surface of the box body 1, and the two ends of the connecting shaft 5 are respectively fixedly connected to the axis of the two sets of speed control wheels 4. When the connecting shaft 5 is fixed, the two sets of speed control wheels 4 slow down their rotation speed, so that the tool cart slows down.

[0028] In the present invention, when in use, the pressing block 64 is pressed by the spring 67. When subjected to a general impact, the collision shell 62 pushes the extrusion rod 61, so that the inclined block 63 pushes the pressing block 64. At this time, the spring 67 generates an opposite force on the inclined block 63 by squeezing the pressing block 64, so that the impact force is weakened. When encountering a larger impact, the collision shell 62 pushes the extrusion rod 61, so that the inclined block 63 pushes the pressing block 64 to rise in the corresponding slide groove through the guide rail 66. The pressing block 64 rises and drives the hinged rod 68 hinged thereto to rise. The hinged rod 68 rises and pulls the clamping rod 66 connected thereto to rotate. 9 rotates around the fixed axis 610, so that the clamping plate 611 clamps the connecting axis 5. The connecting axis 5 is fixedly connected with the two sets of speed control wheels 4. Therefore, when the clamping plate 611 clamps the connecting axis 5, the speed control wheel 4 is decelerated, thereby slowing down the entire tool cart, achieving an anti-collision effect and extending the service life of the tool cart. At the same time, the clamping plate 611 is provided with an arc groove 612 and a rubber sheet 613, so that when the clamping plate 611 clamps the connecting axis 5, the clamping effect is better, and the deceleration effect of the speed control wheel 4 is stronger, thereby making the anti-collision ability of the tool cart stronger and improving the service life of the tool cart.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
