Description

Technical Field

[0001] This invention belongs to the technical field of logistics binding tools, and relates to a locking support structure for a wheel binding device. Background Technology

[0002] When transporting cars by truck, ship, or train, the vehicles need to be secured. Among all the car components, the tires are the easiest to secure without damaging the vehicle. Wheel lashing devices are specifically designed to secure the wheels of a car, preventing it from moving during transport.

[0003] Currently, existing wheel tying devices generally rely on manual operation to tie tires. For example, Chinese patent CN206705126U discloses a tire carrier railcar, which is essentially a wheel tying device. Its features include: two parallel tire carrier connecting beams connected at both ends to tire carrier housings; two bearings fixed inside bearing housings; a roller and roller shaft rotatably connected to the two bearings; the outer end of the roller and roller shaft fixedly connected to a gear, and the inner end connected to a roller shaft connecting rod via a pin; a ratchet placed in a groove on the tire carrier housing; a hexagonal ratchet shaft fixedly connected to the ratchet; a ratchet pawl fixing shaft fixedly connected to the tire carrier housing; a ratchet pawl rotatably connected to the ratchet pawl fixing shaft; one end of the tire strap fixed to the ratchet and the other end fixed to the tire strap pull ring; the tire strap pull ring hinged to one end of the ratchet pawl; the other end of the ratchet pawl meshing with the upper part of the ratchet; and a gear meshing with a rack and pinion guide rail. The specific binding process is as follows: After the car tire is moved into place, the binding strap is manually pulled off the ratchet and wrapped around the tire from bottom to top until the binding strap loop is hinged to the ratchet pawl. At this time, the pawl is not engaged with the ratchet, and the ratchet can rotate clockwise. After completing the pulling and initial binding operation, the ratchet hexagonal shaft is rotated counterclockwise using an Allen socket to drive the tire binding strap to wrap around the ratchet. The binding strap loop pulls the ratchet pawl to rotate counterclockwise around the ratchet's fixed shaft, so that the ratchet pawl engages with the ratchet and cannot rotate clockwise, thus achieving binding and locking, and finally completing the tire binding operation.

[0004] The existing wheel tying devices have the following drawbacks: During vehicle transport, factors such as road conditions and the condition of the transport vehicle can cause the tethered tires to wobble back and forth. This can lead to the tying straps loosening, particularly at the connection between the strap pull ring and the ratchet pawl, where disengagement may occur. This results in poor reliability of the existing tire tying devices, making reliable tire securing impossible. Furthermore, in these devices, when interlocking the strap pull ring with the ratchet pawl, the pull ring must be wound from top to bottom around the outer casing before engaging with the ratchet pawl, making the locking operation inconvenient. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a locking support structure for a wheel tying device. The technical problem this invention aims to solve is how to make the tying device reliable and convenient to use.

[0006] The objective of this invention can be achieved through the following technical solution: a locking support structure for a wheel binding device, the wheel binding device including a platform and a binding member, the upper surface of the platform having a clearance opening for the binding member to pass through, characterized in that the locking support structure includes a locking block one and a locking block two located below the clearance opening, the locking block one and the locking block two being slidably connected to the platform in a horizontal direction, a baffle being provided in the clearance opening, the baffle being located above the locking block two and capable of swinging relative to the platform; the locking block one is driven by a driving member, under the driving member, the locking block one can slide towards the locking block two so that while clamping the binding member, the two can drive the baffle to swing out the clearance opening.

[0007] Unlike existing technologies, this invention designs a novel locking support structure, fundamentally changing the locking method and principle of the binding components to improve the reliability of the binding device and enhance its ease of operation. Specifically, this binding component locking device includes two locking blocks, a first and a second, located below the clearance opening and slidably connected to the platform in a horizontal direction. Driven by a driving component, the first locking block slides towards the second locking block, clamping the binding component. Unlike existing binding components that use a pull ring hook for locking, this clamping design of the two locking blocks makes the binding component less prone to detachment during use, resulting in high reliability. Simultaneously, a baffle is installed within the clearance opening. This baffle is located above the second locking block and can swing relative to the platform. When the driving component drives the first locking block to slide towards the second locking block, the clamping of the binding component simultaneously causes the baffle to swing out of the clearance opening. This baffle works in conjunction with the first and second locking blocks. This design, on the one hand, prevents the tire from swaying back and forth, reducing the tire's swaying amplitude during transport. This design makes the binding member and its locking position less prone to loosening, thus improving the reliability of the binding. On the other hand, when not in use, the baffle is located inside the clearance opening, so that the movement of the tire to the platform for binding is not affected. Furthermore, the upward movement of the baffle is in sliding linkage with locking block one and locking block two. While locking block one and locking block two clamp the binding member, the upward movement of the baffle is achieved. The entire operation only requires one drive component, making it simple and convenient. In summary, when using the locking structure of this binding member, you only need to control the binding member to enter directly from top to bottom between the two locking blocks through the clearance opening. Subsequently, you only need to control the drive component to complete the entire locking operation. Moreover, thanks to the locking of locking block one and locking block two and the blocking action of the baffle, not only is the locking effect good, greatly improving the reliability of the binding device, but the entire operation process is also very simple and convenient.

[0008] In the locking support structure of the aforementioned wheel tying device, the baffle is hinged to the platform, and the baffle or locking block two has a pushing surface. When locking block two slides, it can push the baffle upward by the pushing surface. Through the above hinged arrangement and the design of the pushing surface, the horizontal sliding motion of locking block two can be converted into the upward swinging motion of the baffle, thereby realizing the linkage between the baffle and locking block two. This eliminates the need for additional operation of the baffle swinging, making the device very convenient to use. At the same time, through the above linkage design, when the baffle swings upward to block the tire's back-and-forth swaying, the force on the baffle is transmitted to locking block two through the pushing surface, giving locking block two a tendency to slide towards locking block one. Combined with the force applied by the driving component pushing the locking component one, the two interact, making the tying device lock more tightly during use, thereby further improving the reliability of the device.

[0009] As an alternative, in the locking support structure of the aforementioned wheel-binding device, the baffle is hinged to the second locking block. A lifting rod is provided between the bottom of the baffle and the first locking block. One end of the lifting rod is hinged to the bottom of the baffle, and the other end is hinged to the first locking block. The first locking block can push the baffle upward by the lifting rod. Through this design, the horizontal sliding motion of the first locking block can be converted into the upward swinging motion of the baffle, thereby realizing the linkage between the baffle, the first locking block, and the second locking block. This eliminates the need for additional operation of the baffle swinging, making the device very convenient to use.

[0010] Preferably, in the locking support structure of the wheel binding device described above, the pushing surface is located on the baffle, and the upper part of the second locking block has an arc-shaped pushing portion that abuts against the pushing surface. The pushing surface includes an inclined surface that is inclined relative to the upper surface of the baffle and a straight surface that is parallel to the upper surface of the baffle. This design of the pushing portion makes the linkage between the second locking block and the baffle smoother and less prone to jamming, thereby improving the reliability of the device.

[0011] In the locking support structure of the aforementioned wheel tying device, the bottom of the baffle has a trapezoidal groove, and the upper part of the locking block two has a mating part that matches the shape of the groove. When the baffle is positioned parallel to the platform surface, the mating part is located within the groove and abuts against the inner surface of the groove. Through the design of the groove and the mating part, when the tire moves past the baffle, the support and limiting effect of the locking block two prevents the baffle from jumping, thereby improving the stability of the device and reducing the likelihood of malfunction, thus enhancing its reliability.

[0012] In the locking support structure of the aforementioned wheel binding device, the first locking block has a clamping jaw one, and the second locking block has a clamping jaw two opposite to the clamping jaw one. The locking end of the binding member is fixedly connected to a locking shaft, and the clamping jaw one and clamping jaw two can close together to clamp the locking shaft. Through the cooperative design of the clamping jaw one, clamping jaw two, and locking shaft, the locking reliability of the binding member can be improved, thereby improving the reliability of the device in use.

[0013] In the locking support structure of the aforementioned wheel tying device, the upper part of the first clamp has two horizontally extending blocking parts, and a through-hole communicating with the first clamp is formed between the two blocking parts. The blocking parts can extend into the second clamp and abut against the inner wall of the second clamp. Through the design of the above blocking parts, the blocking parts can completely block the locking shaft located in the two clamps, thereby completely avoiding the problem of the locking shaft disengaging after locking, thus greatly improving the locking reliability. Furthermore, the design of the through-hole can provide clearance space for the body of the tying member, avoiding interference with the clamping of the locking shaft after clamping the body of the tying member, thus contributing to the reliability of the locking shaft clamping, and further improving the reliability of the device in use.

[0014] In the locking support structure of the aforementioned wheel tying device, the platform includes a support plate and a mounting seat located below the support plate. The clearance opening is formed on the support plate, and the mounting seat has a horizontally arranged groove. The opening of the groove communicates with the clearance opening. Locking block one and locking block two are both located within the groove and are slidably connected to it. This design enables the sliding of locking block one and locking block two. Furthermore, the design structure of the mounting seat and the groove is stable and reliable, thus ensuring the reliability of the device.

[0015] In the locking support structure of the aforementioned wheel binding device, the second locking block is reset by a return spring. The return spring is located below the second locking block, with one end fixedly connected to the second locking block and the other end fixedly connected to the platform. This return spring design allows the second locking block to automatically reset using the spring force, thereby improving the ease of use of the device.

[0016] In the locking support structure of the aforementioned wheel tying device, the upper surface of the baffle has several anti-slip teeth arranged at intervals along its length. This anti-slip tooth design allows the baffle to better provide resistance to the tire, making the tire less prone to wobbling during transport, thus making the locking of the device more reliable and improving its overall reliability.

[0017] In the locking support structure of the aforementioned wheel binding device, the driving component is a hydraulic cylinder, a linear motor, or a pneumatic cylinder. The driving component is fixedly connected to the outside of the mounting base, and its drive shaft extends into the slide groove and is fixedly connected to the locking block. This design achieves the driving configuration of the locking structure.

[0018] Compared with existing technologies, the locking support structure of this wheel lashing device has the following advantages:

[0019] 1. This locking support structure, through the cooperative design of locking block one, locking block two and baffle, can not only reduce the shaking of the tire during transportation, but also provide a more effective and reliable locking force for the binding parts, thus making this device have very good reliability in use.

[0020] 2. The entire locking operation can be completed simply by controlling the binding component to enter the space between the two locking blocks from top to bottom through the clearance port, and then controlling the drive component to drive the locking blocks. This makes the device very convenient to use. Attached Figure Description

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] Example 1:

[0032] Specifically, such as Figure 1 and Figure 2 As shown, this wheel binding device includes a platform 1 and a binding member 2, which is a chain or a strap. The platform 1 includes a support plate 11 and a mounting seat 12 located below the support plate 11. The upper surface of the support plate 11 is provided with a clearance opening 1a for the binding member 2 to pass through. The mounting seat 12 has a horizontally arranged groove 121, and the opening of the groove 121 communicates with the clearance opening 1a.

[0033] For example Figure 3 , Figure 4 and Figure 5 As shown, this locking support structure includes a first locking block 3 and a second locking block 4 located below the clearance opening 1a, and a baffle 5 disposed within the clearance opening 1a. Both the first locking block 3 and the second locking block 4 are located within the slide groove 121 and are slidably connected to the slide groove 121. The baffle 5 is hinged to the platform 1. In this embodiment, the baffle 5 has a pushing surface 7, which includes an inclined surface 71 inclined relative to the upper surface of the baffle 5 and a straight surface 72 parallel to the upper surface of the baffle 5. The upper part of the second locking block 4 has an arc-shaped pushing portion 41, which abuts against the pushing surface 7. When the second locking block 4 slides, it can push the baffle 5 upwards via the pushing surface 7. The first locking block 3 is driven by a driving member 6. Under the drive of the driving member 6, the first locking block 3 can slide towards the second locking block 4, so that while clamping the binding member 2, they can also cause the baffle 5 to swing upwards out of the clearance opening 1a. Meanwhile, the bottom of the baffle 5 has a trapezoidal groove 5a, and the upper part of the locking block 4 has a mating part 42 that matches the shape of the groove 5a. When the baffle 5 is in a position parallel to the surface of the platform 1, the mating part 42 is located in the groove 5a and abuts against the inner surface of the groove 5a. Preferably, in this embodiment, the locking block 4 is reset by a return spring 9. The return spring 9 is a tension spring, located below the locking block 4. One end of the return spring 9 is fixedly connected to the locking block 4, and the other end is fixedly connected to the platform 1.

[0034] More specifically, such as Figure 2 , Figure 4 and Figure 6 As shown, locking block 3 has a clamping slot 3a, and locking block 4 has a clamping slot 4a opposite to clamping slot 3a. The locking end of the binding member 2 is fixedly connected to a locking shaft 8. Clamping slots 3a and 4a can close together and clamp the locking shaft 8. The upper part of clamping slot 3a has two horizontally extending blocking parts 3a1. A through-hole 3a2 communicating with clamping slot 3a is formed between the two blocking parts 3a1. The blocking parts 3a1 can extend into clamping slot 4a and abut against the inner wall of clamping slot 4a. Figure 7 As shown, the upper surface of the baffle 5 has a number of anti-slip teeth 51 arranged at intervals along the length direction. The driving component 6 is a hydraulic cylinder, a linear motor, or a pneumatic cylinder. The driving component 6 is fixedly connected to the mounting base 12, and the drive shaft of the driving component 6 extends into the slide groove 121 and is fixedly connected to the locking block 3.

[0035] The working process of the locking support structure in this embodiment is as follows: Figure 3 As shown, in the initial state, locking block 3 and locking block 4 are in an unclosed and locked state, while baffle 5 is parallel to the surface of platform 1, and the mating part 42 of locking block 4 is located in the groove 5a of baffle 5. When the binding member 2 needs to be locked after passing around tire a, simply insert the locking shaft 8 through the clearance opening 1a between locking block 3 and locking block 4. At this time, the control drive member 6 works, and locking block 3 will slide towards locking block 4 under the drive of the drive member 6 until the two are closed. After closing, locking block 3 will continue to push locking block 4 to slide together. At this time, locking block 4 will push baffle 5 to swing upward while sliding until baffle 5 and tire a are pressed together and limited. At this time, the thrust of the drive member 6 on locking block 3 keeps the locking shaft 8 in a locked state, that is, as shown. Figure 4 As shown, the device is currently in a locked and supported state. When unlocking is required, simply control the drive component 6 to retract, and lock block 3 will reset. Lock block 4 will automatically reset via the reset spring 9, and baffle 5 will reset via self-resetting. Of course, if the reset spring 9 is not provided, manual reset is also possible.

[0036] Example 2:

[0037] The technical solution in this embodiment is basically the same as that in Embodiment 1, except that, in this embodiment, as... Figure 8 As shown, the baffle 5 is hinged to the locking block 4. A lifting rod b is provided between the bottom of the baffle 5 and the locking block 3. One end of the lifting rod b is hinged to the bottom of the baffle 5, and the other end of the lifting rod b is hinged to the locking block 3. The locking block 3 can push the baffle 5 to swing upward by the lifting rod b.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0039] Although this document frequently uses terms such as platform 1, clearance opening 1a, bearing plate 11, mounting base 12, slide groove 121, binding member 2, locking block 1 3, clamping opening 1 3a, blocking part 3a1, through opening 3a2, locking block 2 4, clamping opening 2 4a, pushing part 41, mating part 42, baffle 5, groove 5a, anti-slip tooth 51, driving member 6, pushing surface 7, inclined surface 71, flat surface 72, locking shaft 8, return spring 9, tire a, lifting rod b, etc., the possibility of using other terms is not excluded.
