Description

Technical Field

[0001] This utility model relates to the field of handcart technology, and in particular to a foldable handcart railing and handcart. Background Technology

[0002] A handcart is a device used to transport goods. When using a handcart, the goods are placed on top of a support plate, and then the support plate is pushed through the railing, which causes the wheels at the bottom of the support plate to rotate, making it easy to transfer the goods by means of the wheels.

[0003] The inventor discovered in his daily work that the handcart still has at least the following problems: When using the handcart, the goods are placed on top of the support plate, and then the support plate is pushed by the railing, which causes the wheels at the bottom of the support plate to rotate. This makes it easy to transfer the goods by the wheels. However, in actual use, because the railing is fixed to the top of the support plate, a relatively large storage area is required when the handcart needs to be stored, which makes storing the handcart quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a foldable trolley fence and trolley.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable trolley fence and trolley, including a support plate, with movable wheels evenly installed at the bottom of the support plate, and fence bodies evenly arranged at the top of the support plate. A connecting device is provided at the top of the support plate, and the connecting device includes a rotating bar. A groove is opened at the top of the support plate, and the rotating bar is disposed inside the groove. One side of the rotating bar and one side of the groove are hinged together.

[0006] The effect achieved by the above components is that when using the connecting device, the rotating bar can be manually controlled to rotate on one side of the groove, which makes it easier to set the main body of the fence on the top of the support plate, thus reducing the storage volume when storing the handcart.

[0007] Preferably, a fixing groove is provided on one side of both the rotating bar and the support plate, and a U-shaped plate is slidably connected to the inner wall of the fixing groove.

[0008] The effect achieved by the above components is to slide the U-shaped plate into the two fixed grooves, thereby confining the rotating bar inside the grooves.

[0009] Preferably, a damping rod is fixedly connected to one side of the support plate, and the end of the damping rod away from the support plate is fixedly connected to one side of the U-shaped plate. A first spring is sleeved on the surface of the damping rod, and one end of the first spring is fixedly connected to one side of the support plate. The end of the first spring near the U-shaped plate is fixedly connected to one side of the U-shaped plate.

[0010] The effect achieved by the above components is that the U-shaped plate is pulled towards the support plate by the first spring, which makes it easier to confine the U-shaped plate inside the fixed groove.

[0011] Preferably, a rubber block is fixedly connected to the bottom of the inner wall of the groove, and the end of the rubber block away from the groove is located at the top of the rotating bar.

[0012] The effect achieved by the above components is that by placing the end of the rubber block away from the groove at the top of the rotating bar, the rotating bar can be confined inside the groove.

[0013] Preferably, a support device is provided on one side of the fence body, a sliding groove is provided at the bottom of the groove, a sliding rod is fixedly connected to the inner wall of the sliding groove, a sliding block is slidably sleeved on the surface of the sliding rod, and a semi-cylinder is fixedly connected to the top of the sliding block, the semi-cylinder being sleeved on one side of the fence body.

[0014] The effect achieved by the above components is to control the sliding block to slide on the surface of the sliding rod, thereby fitting the semi-cylinder onto one side of the fence body, so that the fence body can be supported by the semi-cylinder.

[0015] Preferably, a second spring is sleeved on the surface of the sliding rod, one end of the second spring is fixedly connected to one side of the inner wall of the sliding groove, and the end of the second spring near the semi-cylinder is fixedly connected to one side of the sliding block.

[0016] The effect achieved by the above components is that the sliding block is pressed towards the inside of the rotating bar by the second spring, which makes it easier to restrict the semi-cylinder to the surface of the fence body.

[0017] Preferably, a positioning rod is slidably inserted through the bottom of the support plate, the positioning rod is slidably inserted through the bottom of the rotating bar, a third spring is sleeved on the surface of the positioning rod, one end of the third spring is fixedly connected to one end of the positioning rod, and the end of the third spring near the support plate is fixedly connected to the bottom of the support plate.

[0018] The effect achieved by the above components is as follows: after the positioning rod passes through the bottom of the support plate, it passes through the bottom of the rotating bar, and then the positioning rod is pulled towards the support plate by the third spring. This makes it easier to confine the positioning rod inside the support plate and the rotating bar, so that the rotating bar and the groove can be tightly connected together.

[0019] Preferably, a rubber sleeve is fixedly connected to the top of the semi-cylinder, the rubber sleeve is fitted onto the surface of one side of the fence body, and a fixing ring is fitted onto the surface of the rubber sleeve, the fixing ring being fitted onto the surface of one side of the fence body.

[0020] The effect achieved by the above components is to press the retaining ring against the surface of the rubber sleeve, which makes it easier to restrict the semi-cylinder to the surface of the fence body.

[0021] In this invention, by setting a connecting device, when using the connecting device, the rotating bar is manually controlled to rotate on one side of the groove, which makes it easier for the main body of the fence to be set on the top of the support plate, thus reducing the storage volume when storing handcarts.

[0027] Example 1, as Figure 1-4 As shown, a foldable trolley fence and trolley are provided. The bottom of the support plate 1 is evenly equipped with movable wheels 3, the top of the support plate 1 is evenly provided with the fence body 2, and the top of the support plate 1 is provided with a connecting device 4. When using the trolley, the goods are placed on the top of the support plate 1, and then the support plate 1 is pushed by the fence, which causes the movable wheels 3 at the bottom of the support plate 1 to rotate, so that the goods can be transferred by the movable wheels 3.

[0028] Reference Figure 2 and Figure 3The connecting device 4 includes a rotating bar 402. A groove 401 is provided on the top of the support plate 1, and the rotating bar 402 is disposed inside the groove 401. One side of the rotating bar 402 and one side of the groove 401 are hinged together. When using the connecting device 4, the rotating bar 402 is manually controlled to rotate on one side of the groove 401, which facilitates the placement of the fence body 2 on the top of the support plate 1, thus reducing the storage volume when storing a handcart. Fixing grooves 403 are provided on one side of both the rotating bar 402 and the support plate 1. A U-shaped plate 404 is slidably connected to the inner wall of the fixing groove 403. Sliding the U-shaped plate 404 into the two fixing grooves 403 confines the rotating bar 402 within the groove 401. A damping rod 405 is fixedly connected to one side of the support plate 1. One end of the rod 405 away from the support plate 1 is fixedly connected to one side of the U-shaped plate 404. A first spring 406 is sleeved on the surface of the damping rod 405. One end of the first spring 406 is fixedly connected to one side of the support plate 1. The other end of the first spring 406 near the U-shaped plate 404 is fixedly connected to one side of the U-shaped plate 404. The U-shaped plate 404 is pulled towards the support plate 1 by the first spring 406, which helps to confine the U-shaped plate 404 inside the fixing groove 403. A rubber block 407 is fixedly connected to the bottom of the inner wall of the groove 401. One end of the rubber block 407 away from the groove 401 is set at the top of the rotating bar 402. By setting one end of the rubber block 407 away from the groove 401 at the top of the rotating bar 402, the rotating bar 402 can be confined inside the groove 401.

[0029] Reference Figure 4A support device 5 is provided on one side of the fence body 2. A sliding groove 501 is provided at the bottom of the groove 401. A sliding rod 503 is fixedly connected to the inner wall of the sliding groove 501. A sliding block 502 is slidably fitted on the surface of the sliding rod 503. A semi-cylinder 505 is fixedly connected to the top of the sliding block 502. The semi-cylinder 505 is fitted on one side of the fence body 2, controlling the sliding block 502 to slide on the surface of the sliding rod 503, thereby fitting the semi-cylinder 505 on one side of the fence body 2. In this way, the semi-cylinder can pass through... 505 supports the main body 2 of the fence. A second spring 504 is fitted onto the surface of the sliding rod 503. One end of the second spring 504 is fixedly connected to one side of the inner wall of the sliding groove 501. The end of the second spring 504 near the semi-cylinder 505 is fixedly connected to one side of the sliding block 502. The second spring 504 presses the sliding block 502 towards the inside of the rotating bar 402, thus confining the semi-cylinder 505 to the surface of the main body 2 of the fence. A positioning rod 508 is slidably inserted through the bottom of the support plate 1. The positioning rod 508 is slidably inserted through the bottom of the rotating bar 402. A third spring 509 is sleeved on the surface of the positioning rod 508. One end of the third spring 509 is fixedly connected to one end of the positioning rod 508. The end of the third spring 509 near the support plate 1 is fixedly connected to the bottom of the support plate 1. After passing through the bottom of the support plate 1, the positioning rod 508 passes through the bottom of the rotating bar 402. Then, the positioning rod 508 is pulled towards the support plate 1 by the third spring 509. This makes it easier to restrict the positioning rod 508 inside the support plate 1 and the rotating bar 402, so that the rotating bar 402 and the groove 401 can be tightly connected together. A rubber sleeve 506 is fixedly connected to the top of the semi-cylinder 505. The rubber sleeve 506 is sleeved on the surface of one side of the fence body 2. A fixing ring 507 is sleeved on the surface of the rubber sleeve 506. The fixing ring 507 is sleeved on the surface of one side of the fence body 2. The fixing ring 507 is pressed against the surface of the rubber sleeve 506, which makes it easier to restrict the semi-cylinder 505 to the surface of the fence body 2.

[0030] Working principle: When using a handcart, the goods are placed on top of the support plate 1, and then the support plate 1 is pushed by the fence, causing the movable wheels 3 at the bottom of the support plate 1 to rotate. This facilitates the transfer of goods by using the movable wheels 3. When using the connecting device 4, the U-shaped plate 404 is slid into the two fixed grooves 403, and the end of the rubber block 407 away from the groove 401 is placed on top of the rotating bar 402. The first spring 406 pulls the U-shaped plate 404 towards the support plate 1, thus confining the U-shaped plate 404 inside the fixed groove 403. This confines the rotating bar 402 inside the groove 401. The operation is reversed, and the rotating bar 402 is manually controlled to rotate on one side of the groove 401, which facilitates the placement of the fence body 2 on top of the support plate 1. This reduces the storage volume when folding up the trolley. When using the support device 5, the positioning rod 508 passes through the bottom of the support plate 1 and then through the bottom of the rotating bar 402. Then, the positioning rod 508 is pulled towards the support plate 1 by the third spring 509. This makes it easier to restrict the positioning rod 508 inside the support plate 1 and the rotating bar 402, so that the rotating bar 402 and the groove 401 can be tightly connected together. The sliding block 502 is controlled to slide on the surface of the sliding rod 503. The second spring 504 presses the sliding block 502 towards the inside of the rotating bar 402, pressing the fixing ring 507 against the surface of the rubber sleeve 506. This makes it easier to restrict the semi-cylinder 505 on the surface of the fence body 2. The fence body 2 can be supported by the semi-cylinder 505.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
