Description

Technical Field

[0001] This application relates to the field of stroller technology, and more particularly to strollers with shock absorption function. Background Technology

[0002] The trolley can be used to transport ultra-thin glass in the ultra-thin glass production line. During transportation, shock-absorbing components are used to protect the glass and prevent it from being bumped or knocked.

[0003] Utility model patent CN220333269U discloses a transport bracket with flexible limiting protection. The key technical features include a fixed platform and a protective component. The fixed platform has a movable groove at its upper end, and the protective component for limiting protection is located inside the movable groove. The protective component includes an operating platform, a slot, clamping blocks, and pressure plates. The operating platform has a slot at its upper end, and clamping blocks are installed on both sides of the slot. This transport bracket with flexible limiting protection allows ultra-thin glass to be sequentially inserted into the slot using the protective component. The movable component drives the clamping blocks inward to clamp the glass. The clamping blocks are made of silicone to protect the edges and corners of the ultra-thin glass. The pressure plates control the clamping force of the clamping blocks, preventing breakage due to excessive clamping force. This protects the ultra-thin glass from damage caused by impacts during transport.

[0004] Regarding the above-mentioned issues, the following technical defects were found: When using this transport bracket to transport ultra-thin glass, because the bracket is not equipped with a shock-absorbing and buffering mechanism, the transport device will bump when it encounters uneven road surfaces, which will easily cause the ultra-thin glass to break during transportation. Utility Model Content

[0005] One of the technical problems this application aims to solve is that the existing ultra-thin glass transport devices do not have shock-absorbing and buffering mechanisms installed, which easily leads to the ultra-thin glass being bumped and broken during transportation.

[0006] To address the aforementioned technical problems, embodiments of this application provide a trolley with shock absorption function, comprising:

[0007] There are two handrails, and the cross-section of the handrails is U-shaped.

[0008] Several shelves, each shelf having two sides fixedly connected to the adjacent sides of two handrails; and

[0009] Several movable shock-absorbing components are located at the lower end of the handrail;

[0010] The movable shock absorption assembly includes pulleys, a top plate, and a bottom plate. An upper shell is fixedly connected to the lower surface of the top plate, and a lower shell is fixedly connected to the upper surface of the bottom plate. The outer wall of the lower shell is slidably connected to the inner wall of the upper shell. Several rubber blocks are fixedly connected to the inner wall of the upper shell, and a rubber ring is fixedly connected to the inner wall of the lower shell. When the lower shell slides along the inner wall of the upper shell and the rubber blocks are inside the lower shell, the rubber blocks and the rubber ring are slidably connected. Several springs are installed inside the lower shell, and the two ends of the springs are fixedly connected to the bottom plate and the rubber blocks, respectively. The pulleys are installed on the lower surface of the bottom plate.

[0011] In some embodiments, a first rubber pad is fixedly connected to the lower end of the upper shell, and a second rubber pad is fixedly connected to the outer wall of the lower shell.

[0012] In some embodiments, a plurality of telescopic rods are fixedly connected to the upper surface of the base plate, the output end of the telescopic rods is fixedly connected to the lower surface of the rubber block, and a spring is sleeved on the outside of the telescopic rods.

[0013] In some embodiments, the top plate is detachably connected to the lower end of the handrail by bolts, and the pulley is detachably connected to the lower surface of the base plate by bolts.

[0014] In some embodiments, the upper surface of the shelf is provided with a soft pad mounting assembly, which includes a connecting frame, two connecting ropes and two positioning posts. The positioning posts have a "T" shaped cross section. The two positioning posts are fixedly connected to the two sides of the shelf respectively. The connecting ropes are looped on the arc surface of the positioning posts and are fixedly connected to the upper surface of the connecting frame. A sponge pad is fixedly connected to the inner wall of the connecting frame.

[0015] In some embodiments, a positioning hole is provided on the upper surface of the shelf, and the inner wall of the positioning hole fits against the connecting frame.

[0016] In some embodiments, two grip grooves are formed on the upper surface of the connecting frame.

[0017] By implementing the above technical solution and setting up mobile shock-absorbing components, the bumps of the glass can be greatly reduced when encountering uneven road surfaces during the transportation of ultra-thin glass using a trolley. This reduces the risk of breakage caused by bumps during transportation and improves the practicality of the transport trolley.

[0018] By installing a soft pad mounting component, when using this trolley to transport glass, the glass can be placed on a sponge pad on the shelf, which can reduce the breakage and scratches of the glass caused by uneven ground or collisions during personnel handling. Moreover, the sponge pad can be easily replaced after it wears out. Attached Figure Description

[0036] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a trolley with shock absorption function, comprising:

[0037] Two handrails 1, each with a U-shaped cross-section; several storage panels 2, each with its two sides fixedly connected to the side of the two handrails 1 closest to each other; and several movable shock-absorbing components 3, located at the lower end of the handrails 1.

[0038] The following section will explain the specific settings and functions of the movable shock absorption component 3 and the soft pad mounting component 4.

[0039] Reference Figures 2 to 5 As shown in this embodiment: the movable shock absorption assembly 3 includes a pulley 311, a top plate 301, and a bottom plate 303. An upper shell 302 is fixedly connected to the lower surface of the top plate 301, and a lower shell 304 is fixedly connected to the upper surface of the bottom plate 303. The outer wall of the lower shell 304 is slidably connected to the inner wall of the upper shell 302. Several rubber blocks 306 are fixedly connected to the inner wall of the upper shell 302, and a rubber ring 307 is fixedly connected to the inner wall of the lower shell 304. When the lower shell 304 slides along the inner wall of the upper shell 302 and the rubber blocks 306 are inside the lower shell 304... At this time, the rubber block 306 is slidably connected to the rubber ring 307. Several springs 305 are installed inside the lower shell 304. The two ends of the springs 305 are fixedly connected to the base plate 303 and the rubber block 306 respectively. The pulley 311 is installed on the lower surface of the base plate 303. By setting the movable shock absorption component 3, the glass can be greatly reduced when encountering uneven road surfaces during the transportation of ultra-thin glass using a trolley. This can reduce the bumps and damage to the ultra-thin glass during transportation and improve the practicality of the transport trolley.

[0040] The lower end of the upper shell 302 is fixedly connected to a first rubber pad 309, and the outer wall of the lower shell 304 is fixedly connected to a second rubber pad 310. When the upper shell 302 moves to the lowest position, the first rubber pad 309 will press against the second rubber pad 310, thereby preventing the upper shell 302 and the lower shell 304 from directly colliding and causing damage.

[0041] Several telescopic rods 308 are fixedly connected to the upper surface of the base plate 303. The output end of the telescopic rod 308 is fixedly connected to the lower surface of the rubber block 306. The spring 305 is sleeved on the outside of the telescopic rod 308. During the contraction or expansion of the spring 305, the telescopic rod 308 can position the spring 305, thereby preventing the spring 305 from shifting.

[0042] The top plate 301 is detachably connected to the lower end of the handrail 1 by means of bolts, and the pulley 311 is detachably connected to the lower surface of the base plate 303 by means of bolts. By making the top plate 301 and the pulley 311 detachable, the damping spring 305 shock absorber and the pulley 311 can be disassembled separately, which facilitates their maintenance and replacement and reduces the cost of use.

[0043] Reference Figure 6 and Figure 7 As shown in this embodiment: the upper surface of the shelf 2 is provided with a soft pad mounting assembly 4. The soft pad mounting assembly 4 includes a connecting frame 41, two connecting ropes 43 and two positioning posts 44. The positioning posts 44 have a "T" shaped cross section. The two positioning posts 44 are fixedly connected to the two sides of the shelf 2 respectively. The connecting ropes 43 are sleeved on the arc surface of the positioning posts 44. The connecting ropes 43 are fixedly connected to the upper surface of the connecting frame 41. A sponge pad 42 is fixedly connected to the inner wall of the connecting frame 41. By setting the soft pad mounting assembly 4, when using the trolley to transport glass, the glass can be placed on the sponge pad 42 on the shelf 2, thereby reducing the breakage and scratches of the glass caused by uneven ground or mutual collisions during personnel handling. Moreover, after the sponge pad 42 is worn out, personnel can easily replace it.

[0044] The upper surface of the shelf 2 is provided with a positioning hole 46. The inner wall of the positioning hole 46 fits against the connecting frame 41. When installing the sponge pad 42, the connecting frame 41 is first placed in the positioning hole 46 on the shelf 2, so that the connecting frame 41 and the sponge pad 42 can be quickly installed in the designated position.

[0045] Two grip grooves 45 are provided on the upper surface of the connecting frame 41, which allows personnel to move the connecting frame 41 by means of the grip grooves 45, thus achieving the effect of convenient control of the connecting frame 41.

[0046] When transporting ultra-thin glass, first place the glass to be transported on the upper surface of the shelf 2. Then, push the handle 1 and use the pulleys 311 to transport the ultra-thin glass. If the trolley vibrates due to uneven road surfaces during transport, the pulleys 311 will first drive the base plate 303, which in turn drives the lower shell 304. The lower shell 304 will move upward along the inner wall of the upper shell 302. At the same time, the lower shell 304 will drive the spring 305, causing the spring 305 to be compressed in the positioning of the telescopic rod 308. After the spring 305 is compressed, it will push the lower shell 304, causing the lower shell 304 to move downward along the inner wall of the upper shell 302. At this time, the rebound force of the spring 305 will be slowly absorbed by the rubber block 30. The friction between the 6 and the rubber ring 307 cancels out the friction, allowing the lower shell 304, base plate 303, and pulley 311 to slowly return to their original positions, thus achieving a shock absorption effect. When the upper shell 302 moves to its lowest position, the first rubber pad 309 will press against the second rubber pad 310, thus preventing the upper shell 302 from directly colliding with the lower shell 304 and causing damage. In addition, during the contraction or expansion of the spring 305, the telescopic rod 308 can position the spring 305, thus preventing the spring 305 from shifting. Finally, by making the top plate 301 and pulley 311 detachable, the damping spring 305 shock absorber and pulley 311 can be disassembled separately, which facilitates their maintenance and replacement and reduces the cost of use.

[0047] When using this trolley to transport glass, the glass can be placed on the sponge pad 42 on the shelf 2, which can reduce the breakage and scratches caused by uneven ground or collisions during personnel handling. When the sponge pad 42 is worn out and needs to be replaced, first pull the connecting rope 43 to separate it from the positioning post 44, and then use the grip groove 45 to move the connecting frame 41 to remove it from the positioning hole 46 on the shelf 2, thus completing the disassembly of the worn sponge pad 42. Then, move the grip groove 45 to move the new connecting frame 41 and sponge pad 42, and place the connecting frame 41 into the positioning hole 46 on the shelf 2, so that the connecting frame 41 and sponge pad 42 can be quickly installed in the designated position. After the connecting frame 41 is in contact with the inner wall of the positioning hole 46, the connecting rope 43 is then looped on the arc surface of the positioning post 44, thus completing the installation of the connecting frame 41 and sponge pad 42.
