[0001] The utility model relates to the technical field of transfer devices, in particular to a transfer device for logistics and e-commerce. Background Art

[0002] Logistics e-commerce refers to the combination of online logistics services and e-commerce activities carried out using Internet technology. Usually, logistics e-commerce platforms provide one-stop logistics solutions, including warehousing, transportation, delivery and other services, while combining e-commerce models to provide users with online shopping, payment, order tracking and other functions. With the support of information technology, logistics e-commerce has realized the digitization and visualization of logistics processes, improved logistics efficiency, reduced costs, and brought convenience to consumers and merchants. Flatbed carts are needed in the transportation process of goods.

[0003] However, when the existing flatbed cart suddenly stops during movement, it will continue to move forward due to inertia, which is prone to collision or falling, and there is a certain degree of danger. In order to solve the above problems, the inventor has proposed a new type of logistics e-commerce commercial transfer device to solve the above problems. Utility Model Content

[0019] One side of the top of the vertical rod 2 is fixedly connected to a mounting plate 10, a rotating rod 11 is rotatably connected between the two mounting plates 10, one end of the rotating rod 11 extends to one side of the mounting plate 10 and is fixedly connected to a ratchet 12, and a pawl 13 is rotatably connected to the side of the mounting plate 10 close to the ratchet 12, and the front end of the pawl 13 is movably inserted into the tooth groove of the ratchet 12.

[0020] By adopting the above technical solution, through the cooperation between the pawl 13 and the ratchet 12, the ratchet 12 is allowed to rotate in one direction while the ratchet 12 is restricted from rotating in another direction, thereby realizing a self-locking function.

[0021] The outer side of the rotating rod 11 is fixedly connected to a symmetrically distributed winding roller 17, and a traction rope 18 is wound around the outer side of the winding roller 17. A placement plate 20 is provided at the top of the base 1, and the placement plate 20 is slidably clamped between the front sides of the two vertical rods 2. One end of the traction rope 18 is fixedly connected to one side of the placement plate 20.

[0022] By adopting the above technical solution and providing the winding roller 17 , it is convenient to wind up the traction rope 18 , and the traction rope 18 is used to pull the placement plate 20 , thereby realizing the vertical movement of the placement plate 20 .

[0023] A fixing block 14 is fixedly connected to one side of the mounting plate 10 close to the pawl 13 , and a tension spring 15 is fixedly connected between the pawl 13 and the fixing block 14 .

[0024] By adopting the above technical solution and providing the tension spring 15 , the pawl 13 can be easily reset, and the front end of the pawl 13 can be tightly engaged with the tooth groove of the ratchet wheel 12 by utilizing the elastic force of the tension spring 15 .

[0025] One end of the rotating rod 11 extends to one side of the mounting plate 10 and is fixedly connected to a turning handle 19 .

[0026] By adopting the above technical solution and providing the turning handle 19 , it is convenient to better rotate and adjust the rotating rod 11 .

[0027] A release lever 16 is fixedly connected to one side of the top end of the ratchet 13 .

[0028] By adopting the above technical solution and providing the unlocking rod 16 , it is convenient to push the pawl 13 to rotate toward the side away from the ratchet 12 , and to pull the pawl 13 out of the tooth groove of the ratchet 12 , thereby releasing the restriction on the rotation of the ratchet 12 .

[0029] Rollers 21 are rotatably connected to the four corners of the bottom end of the base 1 .

[0030] By adopting the above technical solution and providing the roller 21, the device can be better moved.

[0031] Working principle: When the goods are transferred in the logistics e-commerce, by holding the push rod 3 and pushing the base 1, under the action of the gravity of the goods, the push rod 3 is first pushed to rotate vertically, and at the same time, the top of the connecting rod 4 is driven to rotate synchronously, and the top of the telescopic rod 6 is used to limit the connecting rod 4, and at the same time, the telescopic rod 6 is driven to move vertically, thereby driving the friction rubber block 7 and the limit plate 8 to move vertically, and compressing the spring 9 to separate the bottom end of the friction rubber block 7 from the ground, so as to facilitate the movement of the base 1. When it moves to the appropriate position, the vehicle body needs to be braked. By loosening the push rod 3, the elastic force of the spring 9 is used to push the limit plate 8 and the friction rubber block 7 downward, so that the friction rubber block 7 is in close contact with the ground, thereby braking the trolley;

[0032] When the height of the placement plate 20 needs to be adjusted, the handle 19 is turned to drive the rotating rod 11 and the winding rod 17 to rotate, the traction rope 18 is wound up, and the placement plate 20 is pulled upward by the traction rope 18. When the placement plate 20 is adjusted to a suitable height, the elastic force of the tension spring 15 is used to make the front end of the pawl 13 tightly inserted into the tooth groove of the ratchet 12, thereby limiting the reverse rotation of the ratchet 12 and fixing the height of the placement plate 20. When the height of the placement plate 20 needs to be lowered, the unlocking rod 16 is pushed toward the side away from the ratchet 12 to pull the pawl 13 out of the tooth groove of the ratchet 12, thereby releasing the restriction on the reverse rotation of the ratchet 12, and then the gravity of the placement plate 20 is used to drive the rotating rod 11 to rotate in the reverse direction, thereby lowering the height of the placement plate 20.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
