DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The embodiment of the present application solves the problem that the existing transport carts usually have no anti-collision structure design on the side, by providing a structure of an anti-collision transport cart. When the side of the cart collides with an object, if the impact force is large, it is easy to cause damage and deformation at the corners of the cart, and it is also easy to cause damage to the colliding object, thereby causing losses. Generally, the corners of the cart or the surface of the colliding object are protected by paint to prevent rust. After damage and deformation, the collision position of the cart and the collision object are easily exposed and rusted, reducing the service life.
[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0029] The utility model embodiment discloses a structure of an anti-collision transport trolley. Figure 1-6 As shown, it includes a transport trolley frame 1, and anti-collision device installation grooves 2 are opened at the four corners of the transport trolley frame 1. The anti-collision device installation grooves 2 are internally movable and connected with anti-collision mechanisms. The anti-collision mechanisms include:
[0030] An anti-collision base 3 is arranged inside the anti-collision device installation groove 2;
[0031] A buffer spring 4 is arranged inside the anti-collision base 3;
[0032] A bearing shaft seat 5 is arranged on the buffer spring 4;
[0033] The rubber anti-collision wheel 6 is rotatably connected to the bearing shaft seat 5;
[0034] The damper 7 is arranged between the bearing shaft seat 5 and the anti-collision base 3 .
[0035] Furthermore, a limiting tube 8 is provided on the anti-collision base 3, and a support rod 801 is slidably connected inside the limiting tube 8, and the support rod 801 is fixedly connected to the bearing shaft seat 5. The provided support rod 801 and the limiting tube 8 provide support and limit for the bearing shaft seat 5, thereby ensuring the stability of the force on the bearing shaft seat 5;
[0036] When the bearing shaft seat 5 and the rubber anti-collision wheel 6 are collided, the impact force drives the bearing shaft seat 5 and the rubber anti-collision wheel 6 to move and causes the support rod 801 to slide along the inside of the limiting tube 8. The support rod 801 provides lateral support for the bearing shaft seat 5 and the rubber anti-collision wheel 6 to prevent the bearing shaft seat 5 and the rubber anti-collision wheel 6 from moving in the opposite direction and offset, thereby ensuring that the bearing shaft seat 5 and the rubber anti-collision wheel 6 are subjected to stable force, and the damper 7 is subjected to stable force. Therefore, after a collision, the anti-collision mechanism has good stability, the damper 7 has a long service life, the lateral force on the damper 7 is reduced, and the damper 7 will not be twisted.
[0037] Furthermore, a double-wheel bearing shaft 501 is rotatably connected to the bearing shaft seat 5, and rubber anti-collision wheels 6 are fixedly connected to the upper and lower ends of the double-wheel bearing shaft 501. The rubber anti-collision wheels 6 are arranged on the upper and lower sides of the bearing shaft seat 5. The design of the double rubber anti-collision wheels 6 makes the contact area at the collision position large and the force is stable.
[0038] The internal thread of the anti-collision device installation groove 2 is connected with a base fixing pin 201, and the base fixing pin 201 is movably inserted into the inside of the anti-collision base 3. The set base fixing pin 201 allows the anti-collision base 3 to be locked after being clamped into the inside of the anti-collision device installation groove 2, thereby facilitating the disassembly, assembly and maintenance of the anti-collision base 3.
[0039] A universal wheel 101 is provided at the bottom of the transport trolley frame 1, and a push handle 102 is provided at the top of the transport trolley frame 1. The universal wheel 101 and the push handle 102 make the transport trolley frame 1 easy to move.
[0040] The structure of the anti-collision transport trolley uses the anti-collision mechanism designed at the four corners of the transport trolley frame 1 to protect the transport trolley frame 1 when in use. When the four corners of the transport trolley frame 1 are hit, the rubber anti-collision wheels 6 are used to contact the collision object. After the rubber anti-collision wheels 6 are subjected to force, they move laterally together with the bearing shaft seat 5 and drive the buffer spring 4 to compress, and also drive the damper 7 to contract, thereby reducing the impact force of the collision. The bearing shaft seat 5 also drives the support rod 801 to slide along the inside of the limit tube 8.
[0041] The rubber anti-collision wheels 6 are arranged on both the upper and lower sides of the load-bearing shaft seat 5. The design of the double rubber anti-collision wheels 6 makes the contact area at the collision position large and the force stable. Moreover, the rubber anti-collision wheels 6 themselves are made of rubber material, which is elastic and has buffering performance, further reducing the collision impact force.
[0042] When the protective mechanism is damaged, it is also convenient to replace the protective mechanism at the damaged position. During replacement, the base fixing pin 201 is directly removed, and the anti-collision base 3 is taken out from the inside of the anti-collision device mounting groove 2 and replaced with a new one. When the anti-collision base 3 is installed and clamped inside the anti-collision device mounting groove 2, the base fixing pin 201 is directly used to tighten and lock it, so that the installation of the anti-collision base 3 can be achieved. Therefore, the anti-collision base 3 is easy to install, replace and maintain.
[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
