Description

A utility vehicle with anti-collision function Technical Field

[0001] This utility model relates to the field of tool carts, and in particular to a tool cart with anti-collision function. Background Technology

[0002] A tool trolley (or tool cart) is a mobile device used for storing, transporting, and organizing tools and small equipment. It is typically made of metal, plastic, or composite materials. Its core function is to categorize and store tools through a well-designed structure, allowing users to quickly access and move them. It is suitable for industrial production, maintenance work, laboratories, workshops, and other similar settings.

[0003] However, existing utility carts, such as handcarts, are very prone to hard collisions and friction with other objects during use, which can lead to unnecessary damage to the cart body and the objects.

[0004] Therefore, it is essential to invent a utility vehicle with anti-collision capabilities. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a tool cart with anti-collision function. The technical solution is as follows: A tool cart with anti-collision function includes a body, casters, a storage cavity, and a handle frame, wherein: casters are fixedly installed at the four corners of the bottom of the body, a handle frame is fixedly installed on one side of the top of the body, a storage cavity is provided on the upper surface of the body, and mounting cavities are opened around the body. Several support shafts are evenly fixedly installed in the mounting cavities, and each support shaft is detachably and rotatably mounted with an anti-collision cylinder. Half of the anti-collision cylinder is located in the mounting cavity, and the other half is located outside the body.

[0006] The support shaft includes an upper support platform, a lower support platform, and a rotating shaft. The rotating shaft is rotatably installed between the upper and lower support platforms. The upper and lower support platforms are fixedly installed on the vehicle body. The upper support platform is located above the mounting cavity, and the lower support platform is located below the mounting cavity. The rotating shaft is rotatably located within the mounting cavity. The anti-collision cylinder is detachably and rotatably installed on the rotating shaft.

[0007] The anti-collision cylinder includes an I-beam, a rubber cylinder, and a V-shaped notch. The rubber cylinder is coaxially and fixedly installed on the outside of the I-beam. A V-shaped notch is formed between the I-beam and the rubber cylinder. The V-shaped notch is connected to the core of the I-beam. The I-beam and the rubber cylinder are sleeved on the rotating shaft through the V-shaped notch.

[0008] Several rubber columns are uniformly fixed between the I-beam and the rubber cylinder.

[0009] A buffer cavity is formed between the I-beam, the rubber tube, and the rubber column.

[0010] The larger opening of the V-shaped notch faces outwards.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] The overall design of this utility model can prevent hard collisions and friction between the vehicle body and external objects during use, thereby effectively protecting the vehicle body and external objects and preventing unnecessary damage; at the same time, the anti-collision cylinder can be replaced separately in the future, which is more convenient and flexible.

[0021] The present invention will be further described below with reference to the accompanying drawings: Embodiments

[0022] Referring to Figures 1-4, a tool cart with anti-collision function includes a body 1, casters 2, a storage cavity 3, and a handle frame 4. Casters 2 (which can be locked or unlocked) are fixedly installed at the four corners of the bottom of the body 1 by bolts. A handle frame 4 is fixedly installed on one side of the upper part of the body 1 by welding. A storage cavity 3 is provided on the upper surface of the body 1 for placing necessary items. Installation cavities 5 are provided around the body 1 to provide the necessary installation and rotation space for the anti-collision cylinder. Several support shafts are evenly fixedly installed in the installation cavities 5 to support the anti-collision cylinder. Each support shaft has a detachably rotatably mounted anti-collision cylinder. Half of the anti-collision cylinder is located in the installation cavity 5, and the other half is outside the body 1 to prevent direct contact between the body 1 and external objects, thereby buffering and protecting the body 1 and objects and avoiding hard contact and friction between them.

[0023] Specifically, the support shaft includes an upper support platform 6, a lower support platform 7, and a rotating shaft 8. The rotating shaft 8 is rotatably installed between the upper support platform 6 and the lower support platform 7. The upper support platform 6 and the lower support platform 7 are fixedly installed on the vehicle body 1. The upper support platform 6 is located above the mounting cavity 5, and the lower support platform 7 is located below the mounting cavity 5. The rotating shaft 8 is rotatably installed in the mounting cavity 5. The anti-collision cylinder is detachably rotatably installed on the rotating shaft 8. With this structure, when the vehicle body 1 comes into contact with an external object during movement, the anti-collision cylinder can rotate to prevent hard friction. At the same time, when the anti-collision cylinder is squeezed and cannot rotate, the rotating shaft 8 can still rotate, thereby driving the anti-collision cylinder to continue rotating and preventing hard friction between the anti-collision cylinder and the object.

[0024] Specifically, the anti-collision cylinder includes an I-beam cylinder 9, a rubber cylinder 10, and a V-shaped notch 13. The rubber cylinder 10 is coaxially and fixedly installed on the outside of the I-beam cylinder 9 so that the impact force can be buffered by the rubber cylinder 10 in the event of a collision. A V-shaped notch 13 is opened between the I-beam cylinder 9 and the rubber cylinder 10. The V-shaped notch 13 is connected to the core of the I-beam cylinder 9. The I-beam cylinder 9 and the rubber cylinder 10 are sleeved on the rotating shaft 8 through the V-shaped notch 13. The V-shaped notch 13 makes it convenient to disassemble and replace the anti-collision cylinder separately.

[0025] The I-beam tube 9 can be made of a tough, rigid plastic tube to provide it with a certain strength and deformation capacity.

[0026] Specifically, several rubber posts 11 are evenly fixed between the I-beam 9 and the rubber cylinder 10. The setting of the rubber posts 11 can improve the strength of the rubber cylinder 10 and better resist the impact force.

[0027] Specifically, a buffer cavity 12 is formed between the I-beam 9, the rubber cylinder 10, and the rubber column 11. The buffer cavity 12 provides deformation space for the rubber cylinder 10 and the rubber column 11 during a collision.

[0028] Specifically, the V-shaped notch 13 has its large opening facing outwards so that the anti-collision cylinder can be installed on the rotating shaft 8, while preventing the anti-collision cylinder from accidentally falling off the rotating shaft 8.

[0029] In this embodiment, when the vehicle body 1 comes into contact with an external object, the anti-collision cylinder will first come into contact with the external object, thus blocking the vehicle body 1 from contacting the external object.

[0030] In this way, if vehicle body 1 collides with an external object, it can be buffered by the anti-collision cylinder;

[0031] If the vehicle body 1 collides with an external object and moves to the side of the notification, the anti-collision cylinder can rotate accordingly to reduce the friction between them, prevent hard friction between the vehicle body 1 and the external object, and avoid unnecessary damage.

[0032] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
