[0024] See also Figure 1-6 , the utility model provides a retractable transport device technical solution:

[0025] A telescopic transport device, comprising a main conveyor 1, an auxiliary conveyor 2, a connecting assembly 3, a telescopic conveyor 4 and a supporting assembly 5; the main conveyor 1 and the auxiliary conveyor 2 are rotatably connected via two symmetrically arranged connecting assemblies 3, a telescopic conveyor 4 is slidably arranged in the auxiliary conveyor 2, and two supporting assemblies 5 are symmetrically installed on the surfaces of a main bracket plate 1.1 on the main conveyor 1 and an auxiliary bracket plate 2.1 on the auxiliary conveyor 2;

[0026] The main conveyor 1 includes: two symmetrically arranged main support plates 1.1, a main shaft 1.2, a driving motor 1.3 and a first pulley 1.4; both ends of the main shaft 1.2 are inserted through the main support plates 1.1 and a first connecting plate 3.1 is rotatably sleeved on the surface near the end, one end of the main shaft 1.2 is fixedly connected to the output shaft on the driving motor 1.3, and the first pulley 1.4 is fixedly installed on the output shaft on the driving motor 1.3, and a first through hole 1.11 is opened in the end of the main support plate 1.1 away from the main shaft 1.2.

[0027] The auxiliary conveyor 2 includes: two symmetrically arranged auxiliary support plates 2.1, an auxiliary main shaft 2.2, a second pulley 2.3 and a round roller 2.4; the inner sides of the two auxiliary support plates 2.1 are symmetrically provided with slide grooves 2.11 for placing the telescopic conveyor 4; a second through hole 2.12 is provided in the end of the slide groove 2.11 away from the auxiliary main shaft 2.2, which is used to limit the extension length of the telescopic conveyor 4; both ends of the auxiliary main shaft 2.2 are penetrated by the auxiliary support plate 2.1 and a second connecting plate 3.2 is rotatably sleeved on the surface near the end, and a second pulley 2.3 is fixedly mounted on one end of the auxiliary main shaft 2.2, and the first pulley 1.4 and the second pulley 2.3 are connected by belt transmission, and the round roller 2.4 is fixed in the middle of the auxiliary main shaft 2.2, and can drive the round roller 2.4 on the auxiliary conveyor 2 to rotate synchronously during the rotation of the main conveyor 1.

[0028] The connecting assembly 3 includes: a first connecting plate 3.1, a second connecting plate 3.2, a screw rod 3.3 and a wrench 3.4; a through groove 3.11 is provided in the first connecting plate 3.1, a screw rod 3.3 is rotatably arranged in the through groove 3.11, a threaded hole 3.21 is provided in the second connecting plate 3.2, a wrench 3.4 is fixed on the top of the screw rod 3.3, and one end of the bottom of the screw rod 3.3 passes through the through groove 3.11 and is threadedly connected with the threaded hole 3.21; by rotating the wrench 3.4 to rotate the screw rod 3.3, the distance between the first connecting plate 3.1 and the second connecting plate 3.2 is increased or decreased, thereby realizing folding deformation between the main conveyor 1 and the auxiliary conveyor 2. If the wrench is not turned, the distance between the first connecting plate 3.1 and the second connecting plate 3.2 will be too close to allow the auxiliary conveyor 2 to flip to a horizontal position flush with the main conveyor 1. Therefore, the distance between the first connecting plate 3.1 and the second connecting plate 3.2 must be increased by turning the wrench 3.4 to a distance that allows flipping, so that the auxiliary conveyor 2 can flip to a position flush with the main conveyor 1. When the wrench 3.4 is turned back to its original position, the first connecting plate 3.1 and the second connecting plate 3.2 are directly fitted together to avoid a gap or swing between the main conveyor 1 and the auxiliary conveyor 2.

[0029] The telescopic conveyor 4 comprises: two symmetrically arranged slide rail bracket plates 4.1 and two cylindrical rollers 4.2; the slide rail bracket plates 4.1 are slidably penetrated in the slide groove 2.11, and a plurality of third through holes 4.11 of equal size to the second through holes 2.12 are evenly distributed on the slide rail bracket plates 4.1, so as to facilitate the control of the extended length; the two cylindrical rollers 4.2 are rotatably arranged between the adjacent ends of the two slide rail bracket plates 4.1, and the conveyor belt 24 is installed on the surface of the round roller 2.4 and the two cylindrical rollers 4.2.

[0030] One end of the two slide rail support plates 4.1 on the telescopic conveyor 4 can be inserted into the inner side of one end of the two main support plates 1.1 on the main conveyor 1 away from the main shaft 1.2, and fixedly connected by inserting the pin shaft 6 in the first through hole 1.11 and the third through hole 4.11, thereby realizing the mutual assembly and connection of multiple devices and increasing the transportation distance.

[0031] The support component 5 includes: two symmetrically distributed limit slots 5.1 respectively opened on the main support plate 1.1 and the secondary support plate 2.1, a spring piece 5.2 fixed inside the middle of the limit slot 5.1, a sliding rod 5.3 slidably arranged in the limit slot 5.1, a leg 5.4, and two symmetrically distributed first plug plates 5.5 in a "C" - shaped structure respectively fixed on the main support plate 1.1 and the secondary support plate 2.1, and a second plug plate 5.6 fixed on the outside of the top end 5.11 of the limit slot 5.1; the spring piece 5.2 is used to block the sliding rod 5.3 inside the side end 5.12 in the middle of the slot, so that the leg 5.4 is always inserted into the first plug plate 5.5. The bottom edge of the sliding rod 5.3 protrudes outward, the top end of the sliding rod 5.3 is fixed to one end of the leg 5.4, and one end of the leg 5.4 is movably inserted into the second plug plate 5.6 to prevent the leg 5.4 from rotating between the secondary support plate 2.1 when standing and thus tipping over, increasing the stability of the leg; the other end of the leg 5.4 is movably inserted into the first plug plate 5.5, and the first plug plate 5.5 and the second plug plate 5.6 have the same structure. The limit slot 5.1 is in the shape of a character structure, including a top end 5.11 of the slot, a side end 5.12 in the middle of the slot, and a bottom end 5.13 of the slot. The spring piece 5.2 is in an arc structure, one end of the spring piece 5.2 is fixed to the side end 5.12 in the middle of the slot, and the other end of the spring piece 5.2 faces the top end 5.11. During the process of opening the leg 5.4, it is necessary to horizontally slide the leg 5.4 so that the sliding rod 5.3 slides from the side end 5.12 in the middle of the slot into the space between the top end 5.11 and the bottom end 5.13 of the slot. At this time, the leg 5.4 just slides out of the first plug plate 5.5. Then, turn the other end of the leg 5.4 downward to make it vertically arranged, and then slide the leg 5.4 upward so that one end of its top is inserted into the second plug plate 5.6 to complete the support, fixation and limitation of the conveyor.

[0032] The working principle is as follows: First, rotate the wrench 3.4 to make the screw 3.3 rotate, so that the distance between the first connecting plate 3.1 and the second connecting plate 3.2 increases, and the secondary conveyor 2 is flipped. After it is leveled, turn the wrench 3.4 back to its original position so that the first connecting plate 3.1 and the second connecting plate 3.2 are directly in contact; then slide one end of all the legs 5.4 and insert them into the second plug plate 5.6 to complete the support, fixation and limitation of the conveyor. The length of the telescopic conveyor 4 can also be adjusted by sliding. The length of the extended telescopic conveyor 4 is limited by inserting the pin shaft 6 into the second through - hole 2.12 and the third through - hole 4.11, and finally the conveyor belt is installed on the round roller 2.4 and the two cylindrical rollers 4.2; operating in the reverse way can complete the folding of the device.

[0033] According to the actual length requirement, multiple devices of this invention can be prepared, and one end of the two slide rail bracket plates 4.1 of the telescopic conveyor 4 on another device can be inserted into the inner side of one end of the two main bracket plates 1.1 of the main conveyor 1 on this device, and fixedly connected by inserting the pin shaft 6, so that multiple devices of this invention can be assembled and connected to each other, thereby increasing the transportation distance.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
