[0033] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0034] The present application provides a cargo transmission device for cargo transmission, which can be used for transmission of cargo in any direction.

[0035] like Figure 1 and Figure 2 As shown, the cargo transmission device 10 provided in the present application includes a mounting base 1, a roller 2, a rotating body 3, a rotating shaft 4, a ball 5, a compression spring 6, a handle rod 7, a blocking cover 8 and a locking block 9.

[0036] Mounting base 1 is fixedly mounted in floor 20, with its upper surface flush with floor 20. A vertical circular blind hole 11 is provided in the middle of the upper surface of mounting base 1. A laterally extending sliding hole 12 is provided on the side of mounting base 1. Sliding hole 12 communicates with circular blind hole 11, and a relatively short slide groove 13 is provided above sliding hole 12, communicating with sliding hole 12. In some embodiments of the present application, sliding hole 12 is a circular hole, and slide groove 13 is a rectangular groove. Furthermore, the width of slide groove 13 can be set to be smaller than the diameter of sliding hole 12, thereby limiting the position of locking block 9.

[0037] The locking block 9 is shaped to fit within the sliding hole 12. In this embodiment, the locking block 9 is cylindrical. The locking block 9 is positioned within the sliding hole 12, and the movement of the locking block 9 within the sliding hole 12 is controlled to limit the position of the rotating body 3. In a preferred embodiment, the left side of the locking block 9 (i.e., the side of the rotating body 3) is provided with an inclined surface facing the insertion direction of the rotating body 3, which is inserted into the annular groove 33 of the rotating body 3.

[0038] In the present application, the blocking cover 8 is a circular cake structure, which is installed at the end surface of the sliding hole 12 of the mounting base 1 to block the sliding hole 12.

[0039] The compression spring 6 is arranged in the sliding hole 12 of the mounting base 1 and is located between the locking block 9 and the blocking cover 8 to provide elastic force for the locking block 9 .

[0040] The handle bar 7 is disposed in a slide groove 13 of the mounting base 1, with one end fixedly connected to the locking block 9 and the other end protruding from the upper surface of the mounting base 1. The handle bar 7 can be used to control the locking block 9 to slide within the sliding hole 12 of the mounting base 1. At the same time, the range of motion of the handle bar 7 is limited by the slide groove 13. In some embodiments of the present application, the handle bar 7 can be a long rectangular structure or a round rod structure.

[0041] The rotating body 3 is used to support the stick 2. The rotating body 3 includes a lower cylinder 31 adapted to the circular blind hole 11, a middle cylinder 32 arranged on the upper surface of the mounting base 1, and a bracket 34 for supporting the stick 2. The lower cylinder 31 and the middle cylinder 32 form a stepped structure, and the diameter of the middle cylinder 32 is larger than the diameter of the lower cylinder 31.

[0042] The lower cylinder 31 of the rotating body 3 is placed in the circular blind hole 11 of the mounting base 1, and a circle of annular grooves 33 are provided on the lower cylinder 31 of the rotating body 3, and the position of the annular groove 33 is adapted to the position of the locking block 9. The lower surface of the middle cylinder 32 of the rotating body 3 is evenly distributed with a plurality of ball mounting grooves for mounting the balls 5. In some embodiments of the present application, the ball mounting grooves can be set to 3 to 5, and the ball mounting grooves are semicircular grooves. The bracket 34 is provided on the upper surface of the middle cylinder 32 of the rotating body 3. In some embodiments of the present application, the bracket 34 can be composed of two support plates, and the two support plates are fixed on the middle cylinder 32 of the rotating body 3. The stick 2 is provided between the two support plates through the rotating shaft 4, and the rolling rod 2 can roll around the rotating shaft 4.

[0043] The ball 5 is disposed in the ball mounting groove and is restrained by a retaining ring 51. In some embodiments of the present application, the retaining ring 4 is a circular disk structure with a tapered through-hole on its upper surface facing downward. The tapered through-hole restrains the ball 5 in the semicircular groove of the rotating body 3. The lower end of the ball 5 passes through the tapered through-hole of the retaining ring 4 and contacts the upper surface of the mounting base 1.

[0044] When in use, the lower cylinder 31 of the rotating body 3 is inserted into the circular blind hole 11 of the mounting base 1, and the left inclined surface of the locking block 9 is squeezed by the lower end of the rotating body 3 and retracted into the sliding hole 12 of the mounting base 1. When the ball 5 contacts the upper surface of the mounting base 1, the left end of the locking block 9 enters the annular groove 33 of the rotating body under the action of the compression spring 6, thereby fixing the rotating body 3 on the mounting base 1. By evenly arranging multiple groups of cargo transmission devices 10 on the surface of the floor 20, cargo can be quickly transmitted through the roller 2.

[0045] When not in use, the handle bar 7 is pushed a certain distance to the right (i.e., away from the rotating body 3) so that the left end of the locking block 9 completely enters the sliding hole 12 of the mounting base 1. At this time, the locking block 9 releases the lock on the rotating body 3, and the rotating body 3 can be removed from the mounting base 1, thereby ensuring the flatness of the surface of the floor 20, which is convenient for people to walk or stack goods.

[0046] The present application adopts a combination of rollers and balls. On the basis of ensuring the safe carrying of goods, the rollers can realize the rapid transmission function of the goods. Since multiple balls can rotate freely around the axis of the rotating body 3, the goods can be quickly adjusted in any direction, thereby achieving the rapid transmission effect of the goods in any direction; by setting the combination mode of the annular groove of the rotating body, the inclined surface of the locking block and the compression spring, when the inclined surface of the locking block is squeezed downward and retracted into the sliding hole of the mounting base, the inclined surface of the locking block will extend out of the sliding hole of the mounting base under the action of the compression spring after being unsqueezed, thereby realizing the rapid and automatic locking of the rotating body on the mounting base, reducing manual operation, and ensuring the reliable locking effect of the rotating body under external collision and vibration environments.

[0047] The present application integrates cargo transmission into a simple device, which reduces costs, has high reliability, and realizes the transmission of cargo in any direction. The device is simple, firm, easy to use, and is not restricted by external conditions.

[0048] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
