Description

Technical Field

[0001] The utility model belongs to the technical field of object-carrying carts, and more specifically, particularly relates to an object-carrying type cart. Background Art

[0002] The use of cargo trolleys is very popular in factory workshops, warehouses, supermarkets or supermarkets. In factory workshops or warehouses, workers can use cargo trolleys to easily pull heavy metal parts or other raw materials, finished products and semi-finished products.

[0003] The storage boxes that come with existing trolleys are mostly fixed and do not have the function of adjusting the height of the storage boxes. When a user places relatively high objects between two adjacent sets of storage boxes, the process is rather cumbersome and objects may not be placed. This makes it impossible to fully utilize the space in the storage box and has certain limitations.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a load-carrying trolley is provided to achieve the purpose of having more practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a cargo-carrying trolley, which is achieved by the following specific technical means:

[0007] Preferably, the loading assembly comprises a loading box, and slide rails are installed on both sides of the left and right sides of the loading box. Both ends of the slide rails on the left and right sides are provided with bayonet holes matching the outer walls of the columns, and are respectively installed on the outer walls of the columns on the left and right sides through the bayonet holes.

[0008] Preferably, a handle is installed on one side of the cargo box.

[0009] Preferably, the spring is disposed between one side of the gear and the inner wall of the circular groove.

[0010] Preferably, the circular grooves are provided with spaces for the gears to move.

[0011] Preferably, a slide groove for the cargo box to slide is provided on one side of the slide rail, and convex strips matching the slide groove are provided on both left and right sides of the cargo box, and a limiting protrusion is installed at the end of the convex strip away from the handle.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model provides a lock pin and a driving inclined surface on one side of the lock pin, so that the height of the object-carrying assembly can be adjusted, so as to place relatively high objects. At the same time, the driving inclined surface, the side of the slide rail and the handle are used in coordination, so that the object-carrying assembly can be quickly disassembled, so that the user can clean and maintain the object-carrying assembly;

[0014] 2. The utility model can realize the rotation of the locking pin through the coordinated use of the rack, the gear and the adjusting rod, so as to change the direction of the driving inclined surface on one side of the locking pin, thereby facilitating the user to install the loading assembly; by setting the coordinated use of the threaded rod, the adjusting rod and the base plate, the user can rotate the threaded rod to drive the adjusting rod to rise, and then use the adjusting rod to drive the two sets of racks to rise, so as to realize a single drive to rotate the locking pins on the two sets of columns, thereby providing convenience for the user; at the same time, the self-locking property of the threaded rod can be used to avoid the rack sliding when the rack drives the gear to rise, and has higher stability.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides a loading type trolley, comprising a bottom plate 101, wherein the four corners of the bottom end of the bottom plate 101 are all provided with moving wheels 2, the four corners of the top end of the bottom plate 101 are all fixedly provided with columns 102, a plurality of groups of loading components are commonly installed between four groups of columns 102, a pair of columns 102 on the left and right sides have inner walls provided with circular grooves, locking pins 7 are all installed in the circular grooves, a driving inclined surface is provided on one side of the locking pin 7, base plates 12 are installed at the tops of the four groups of columns 102, threaded rods 4 are installed at the tops of the two groups of base plates 12, an adjusting rod 3 is installed on the outer wall of the threaded rod 4, a rectangular groove matching the bottom end of the adjusting rod 3 is opened at the tops of the four groups of columns 102, the rectangular grooves are communicated with the circular grooves, racks 9 are installed in the rectangular grooves, the outer walls of the locking pins 7 are all fixedly covered with gears 10, a plurality of gears 10 are all meshed with the racks 9, and a spring 11 is also installed on the outer wall of the locking pin 7.

[0027] Among them, the loading assembly includes a loading box 5, and slide rails 6 are installed on the left and right sides of the loading box 5. Both ends of the slide rails 6 on the left and right sides are provided with snap-fits matching the outer walls of the columns 102, and are respectively installed on the outer walls of the left and right columns 102 through the snap-fits.

[0028] A handle 8 is installed on one side of the carrying box 5 , and this design provides convenience for the user to disassemble or place items in the carrying box 5 .

[0029] The spring 11 is disposed between one side of the gear 10 and the inner wall of the circular groove.

[0030] There is space in the circular groove for the gear 10 to move, and this design avoids affecting the rotation and sliding of the gear 10 in the circular groove.

[0031] Among them, a slide groove 14 for the cargo box 5 to slide is opened on one side of the slide rail 6, and convex strips 13 matching the slide groove 14 are arranged on the left and right sides of the cargo box 5. A limiting protrusion 15 is installed at the end of the protrusion 13 away from the handle 8. By setting the limiting protrusion 15, the cargo box 5 can be prevented from detaching from the slide rail 6.

[0032] The working principle of this embodiment is as follows: when in use, the user can push the adjustment rod 3 to move the utility model as a whole, and can pull the handle 8 to drive the object box 5 to slide, so as to place objects in the object box 5; when it is necessary to disassemble the object carrier assembly or adjust the height, the user can directly lift it up through the handle 8. During this process, the edges of the object carrier 5 and the slide rail 6 are in contact with the driving inclined surface on one side of the lock pin 7, thereby driving the lock pin 7 to enter the circular groove, and the lock pin 7 squeezes the spring 11 through the gear 10. When the edges of the object carrier 5 and the slide rail 6 are in contact with the driving inclined surface on one side of the lock pin 7, the spring 11 drives the gear 10 to push the lock pin 7 out through elastic potential energy; when it is necessary to install the object carrier assembly, the user rotates the threaded rod 4, and drives the adjustment rod 3 to rise by rotating the threaded rod 4, and drives the two sets of racks 9 to rise by the bottom end of the adjustment rod 3. The rising of the rack 9 drives the gear 10 to rotate, and the gear 10 drives the lock pin 7 to rotate, thereby changing the direction of the driving inclined surface on one side of the lock pin 7. At this time, the user can install the object carrier assembly.

[0033] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
