Description

Technical Field

[0001] The utility model belongs to the technical field of logistics bundling tools and relates to a locking and supporting structure of a wheel bundling device. Background Art

[0002] During the transportation of an automobile by truck, ship or train, it is necessary to fix the automobile. The tires of the automobile are the components that can be easily fixed and will not damage the automobile among all the components of the automobile. Among them, the wheel bundling device is a device for fixing the wheels of an automobile to prevent the vehicle from moving randomly during transportation.

[0003] Currently, the existing wheel bundling devices generally bundle the tires by manual operation. For example, Chinese Patent CN206705126U discloses a tire bracket rail vehicle, which is actually also a wheel bundling device. Its characteristics are as follows: both ends of two parallel tire bracket connecting crossbeams are respectively connected to the tire bracket housing. Two bearings are fixed in the bearing outer sleeves. The roller and the roller shaft are rotatably connected to the two bearings. The outer end of the roller and the roller shaft is fixedly connected to the gear, and the inner end is connected to the roller shaft connecting rod through a pin shaft. The ratchet is placed in the groove on the tire bracket housing. The ratchet hexagon shaft is fixedly connected to the ratchet. The ratchet pawl fixing shaft is fixedly connected to the tire bracket housing. The ratchet pawl is rotatably connected to the ratchet pawl fixing shaft. One end of the tire strap is fixed to the ratchet, and the other end is fixed to the tire strap pull ring. The tire strap pull ring is hinged to one end of the ratchet pawl. The other end of the ratchet pawl is meshed and connected to the upper part of the ratchet. The gear is meshed and connected to the rack guide rail. The specific bundling operation process is as follows: when the automobile tire moves in place, the strap is manually pulled out from the ratchet and wound around the upper part of the tire from bottom to top until the strap pull ring is hingedly connected to the ratchet pawl. At this time, the pawl is not buckled on the ratchet, and the ratchet can rotate clockwise. After completing the pulling and preliminary bundling operations, then use an inner hexagon socket to rotate the ratchet hexagon shaft counterclockwise to drive the tire strap to wind around the ratchet. The strap pull ring pulls the ratchet pawl to rotate counterclockwise around the ratchet fixing shaft, so that the pawl of the ratchet pawl catches the ratchet and cannot rotate clockwise, thereby realizing bundling and locking, and finally completing the bundling operation of the tire.

[0004] The above existing wheel bundling devices have the following defects: when the vehicle is in transit, affected by factors such as road conditions and the vehicle condition of the transfer vehicle, the bundled tires are prone to front-back shaking, and the above straps are easily loosened by this influence. In particular, the connection between the strap pull ring and the ratchet pawl may also be unhooked, resulting in poor reliability of the existing tire bundling device and inability to achieve reliable bundling of the tires. Moreover, in the above device, when operating the hook interlock timing of the strap pull ring and the ratchet pawl, it is necessary to make the pull ring bypass the housing from top to bottom and then cooperate with the ratchet pawl for connection, resulting in inconvenient locking operation of the strap. Content of the Utility Model

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a locking support structure for a wheel binding device. The technical problem to be solved by the present invention is how to make the binding device reliable and convenient to use.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a locking support structure for a wheel binding device, the wheel binding device includes a carrier and a binding piece, the upper surface of the carrier is provided with a clearance opening for the binding piece to pass through, and it is characterized in that the locking support structure includes a locking block 1 and a locking block 2 located below the clearance opening, the locking block 1 and the locking block 2 are both slidably connected to the carrier in the horizontal direction, a baffle is provided in the clearance opening, the baffle is located above the locking block 2 and can swing relative to the carrier; the locking block 1 is driven by a driving member, and under the drive of the driving member, the locking block 1 can slide toward the locking block 2 so that the two can drive the baffle to swing out of the clearance opening while clamping the binding piece.

[0007] Different from the prior art, the present invention achieves the purpose of improving the reliability of the binding device by designing a new locking support structure and completely changing the locking method and principle of the binding piece, and is easy to operate. Specifically, the binding piece locking device includes a lock block 1 and a lock block 2 which are arranged below the clearance port and are both slidably connected to the carrier in the horizontal direction. Under the drive of the driving member, the lock block 1 can slide toward the lock block 2 so that the two can clamp the binding piece. Different from the existing binding piece locking method through the pull ring hook, the clamping design of the above two lock blocks makes the binding piece not easy to fall out during use, and has high reliability. At the same time, a baffle is provided in the clearance port, which is located above the lock block 2 and can swing relative to the carrier. When the driving member drives the lock block 1 to slide toward the lock block 2, the two can drive the baffle to swing out of the clearance port while clamping the binding piece, that is, the baffle cooperates with the lock block 1 and the lock block 2. After such a design, on the one hand, the baffle that swings out of the clearance port can block the front and back shaking of the tire, which is beneficial to reduce the shaking amplitude of the tire during the transportation process. This makes it difficult for the binding piece and its locking position to loosen, thereby improving the reliability of the binding; on the other hand, the above-mentioned baffle is located in the yield mouth when not in use, so that the tire is not affected when it is moved to the carrier for binding operation, and the above-mentioned baffle swings up in conjunction with the sliding linkage of locking block 1 and locking block 2, and the baffle swings up while locking block 1 and locking block 2 clamp the binding piece. The entire operation process only requires one driving member to drive, and the operation is simple and convenient; therefore, in summary, when the locking structure of this binding piece is in use, it is only necessary to control the binding piece to directly enter between the two locking blocks from the yield mouth from top to bottom, and then it is only necessary to control the driving member to complete the entire locking operation, and with the locking of locking block 1 and locking block 2 and the blocking cooperation of the baffle, not only the locking effect is good, the reliability of the binding device is greatly improved, and the entire operation process is very simple and convenient.

[0008] In the locking support structure of the wheel binding device mentioned above, the baffle is hinged to the carrier, and the baffle or the locking block 2 has a pushing surface, and the locking block 2 can push the baffle to swing up by the pushing surface when sliding. Through the above hinged setting and the design of the pushing surface, the horizontal sliding movement of the locking block 2 can be converted into the upward swinging movement of the baffle, thereby realizing the linkage setting of the baffle and the locking block 2, so that there is no need for additional operation of the baffle swing, making the device very convenient to use; at the same time, through the above linkage design, when the baffle swings up to block the front and back shaking of the tire, the force exerted on the baffle will be transmitted to the locking block 2 through the pushing surface, so that the locking block 2 has a tendency to slide toward the locking block 1, and combined with the force applied by the driving member to push the locking member 1, the two interact with each other, so that the binding member can be locked tighter during use, thereby further improving the reliability of the device.

[0009] As an alternative, in the locking and supporting structure of the above-mentioned wheel bundling device, the baffle is hinged to the second lock block, and a lifting rod is provided between the bottom of the baffle and the first lock block. One end of the lifting rod is hinged to the bottom of the baffle, and the other end of the lifting rod is hinged to the first lock block. The first lock block can push the baffle to swing upward by means of the lifting rod. Through the above design, the horizontal sliding movement of the first lock block can be converted into the upward swinging movement of the baffle, so as to realize the linkage setting of the baffle, the first lock block and the second lock block, thus eliminating the need for additional operation of the baffle to swing, making the device very convenient to use.

[0010] Preferably, in the locking and supporting structure of the above-mentioned wheel bundling device, the pushing surface is located on the baffle, and the upper part of the second lock block has a top-pushing part in an arc shape. The top-pushing part abuts against the pushing surface, and the pushing surface includes an inclined surface inclined relative to the upper surface of the baffle and a flat straight surface parallel to the upper surface of the baffle. Through the design of the above-mentioned top-pushing part, the cooperation between the second lock block and the baffle is smoother during the linkage process and is not prone to jamming, which is beneficial to improving the reliability of the device.

[0011] In the locking and supporting structure of the above-mentioned wheel bundling device, the bottom of the baffle has a groove with a trapezoidal cross-section, and the upper part of the second lock block has a matching part with a shape matching that of the groove. When the baffle is in a position parallel to the surface of the carrier, the matching part is located in the groove and abuts against the inner surface of the groove. Through the design of the above groove and matching part, when the tire moves past the baffle, with the support and limit of the second lock block, the baffle is not prone to bounce, which is beneficial to improving the stability of the device, making the device not prone to failure, and further beneficial to improving the reliability of the device.

[0012] In the locking and supporting structure of the above-mentioned wheel bundling device, the first lock block has a first clamping opening, and the second lock block has a second clamping opening opposite to the first clamping opening. The locking end of the bundling member is fixedly connected with a locking shaft, and the first clamping opening and the second clamping opening can be closed together to clamp the locking shaft. Through the combined design of the first clamping opening, the second clamping opening and the locking shaft, the locking reliability of the bundling member can be improved, thereby improving the reliability of the device.

[0013] In the locking support structure of the wheel binding device described above, the upper portion of the first clamp has two blocking parts extending in the horizontal direction, and a through-hole communicating with the first clamp is formed between the two blocking parts, and the blocking part can extend into the second clamp and abut against the inner wall of the second clamp. Through the design of the above blocking part, the blocking part can completely block the locking shaft located in the two clamps, thereby completely avoiding the problem of the locking shaft being unhooked after locking, thereby greatly improving the locking reliability; and the design of the through-hole can provide space for the main body of the binding piece, avoiding interference with the clamping of the locking shaft after clamping the main body of the binding piece, thereby facilitating the reliability of the clamping of the locking shaft, thereby facilitating the use reliability of the device.

[0014] In the locking support structure of the wheel tying device described above, the platform includes a load-bearing plate and a mounting seat located below the load-bearing plate. The opening is provided on the load-bearing plate. The mounting seat has a horizontally arranged chute, the notch of the chute communicating with the opening. The first and second locking blocks are both located within the chute and are slidably connected to the chute. Through the above design, the sliding arrangement of the first and second locking blocks is achieved, and the design structure of the mounting seat and the chute is stable and reliable, thereby facilitating the reliability of the device.

[0015] In the locking support structure of the wheel lashing device described above, the second locking block is reset by a return spring located below the second locking block. One end of the return spring is fixedly connected to the second locking block, and the other end is fixedly connected to the platform. This design of the return spring 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 wheel lashing device, the upper surface of the baffle has a plurality of anti-slip teeth spaced along its length. This anti-slip design allows the baffle to better provide a stopping force for the tire, making it less susceptible to shaking during transport. This makes the locking mechanism more reliable, thereby improving the reliability of the device.

[0017] In the locking support structure of the wheel binding device, the driving member is a hydraulic cylinder, a linear motor, or a pneumatic cylinder, which is fixedly connected to the outside of the mounting base, and the driving shaft of the driving member extends into the slide groove and is fixedly connected to the locking block. Through the above design, the driving arrangement of the locking structure is realized.

[0018] Compared with the prior art, the locking support structure of the wheel binding device has the following advantages:

[0019] 1. The locking support structure, through the coordinated design of locking block 1, locking block 2 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 the device very reliable in use;

[0020] 2. The entire locking operation can be completed by simply controlling the binding piece to enter between the two locking blocks from the top to the bottom through the clearance opening, and then controlling the driving piece to drive the locking blocks, thereby making the device very convenient to use.

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present utility model and, in combination with the accompanying drawings, further describe the technical solutions of the present utility model. However, the present utility model is not limited to these embodiments.

[0031] Embodiment 1:

[0032] Specifically, as shown in Figure 1 and Figure 2 , this wheel bundling device includes a carrier 1 and a bundling member 2, and the bundling member 2 is a chain or a strap. Among them, the carrier 1 includes a bearing plate 11 and a mounting seat 12 located below the bearing plate 11. A relief opening 1a for the bundling member 2 to penetrate is provided on the upper surface of the bearing plate 11. A chute 121 arranged in the horizontal direction is provided in the mounting seat 12, and the notch of the chute 121 communicates with the relief opening 1a.

[0033] Again, as shown in Figure 3 , Figure 4 and Figure 5 , this locking and supporting structure includes a first locking block 3 and a second locking block 4 located below the relief opening 1a, and a baffle 5 provided in the relief opening 1a. Both the first locking block 3 and the second locking block 4 are located in the chute 121 and are respectively slidably connected to the chute 121. The baffle 5 is hinged to the carrier 1. In this embodiment, the baffle 5 has a pushing surface 7, and the pushing surface 7 includes an inclined surface 71 inclined relative to the upper surface of the baffle 5 and a flat surface 72 parallel to the upper surface of the baffle 5. The upper part of the second locking block 4 has a top-pushing portion 41 in an arc shape, and the top-pushing portion 41 abuts against the pushing surface 7. When the second locking block 4 slides, it can push the baffle 5 to swing upward by means of 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 the two can clamp the bundling member 2 while driving the baffle 5 to swing upward out of the relief opening 1a. At the same time, the bottom of the baffle 5 has a trapezoidal cross-section groove 5a, and the upper part of the second locking block 4 has a matching portion 42 matching the shape of the groove 5a. When the baffle 5 is in a position parallel to the surface of the carrier 1, the matching portion 42 is located in the groove 5a and abuts against the inner surface of the groove 5a. Preferably, in this embodiment, the second locking block 4 is reset by a return spring 9. The return spring 9 is a tension spring. The return spring 9 is located below the second locking block 4. One end of the return spring 9 is fixedly connected to the second locking block 4, and the other end is fixedly connected to the carrier 1.

[0034] More specifically, as shown in Figure 2 , Figure 4 and Figure 6As shown, the locking block 1 has a clamping opening 3a, and the locking block 2 has a clamping opening 4a opposite to the clamping opening 3a. The locking end of the binding member 2 is fixedly connected to the locking shaft 8. The clamping openings 1a and 2a can be closed together to clamp the locking shaft 8. The upper part of the clamping opening 1a has two blocking portions 3a1 extending in the horizontal direction. A through hole 3a2 is formed between the two blocking portions 3a1 and communicates with the clamping opening 1a. The blocking portion 3a1 can extend into the clamping opening 2a and abut against the inner wall of the clamping opening 2a. Figure 7 As shown, the upper surface of the baffle 5 has a plurality of anti-slip teeth 51 spaced apart along the length. The driving member 6 is a hydraulic cylinder, a linear motor, or a pneumatic cylinder. The driving member 6 is fixedly connected to the outside of the mounting base 12, and the driving shaft of the driving member 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, the lock block 1 3 and the lock block 2 4 are in an unclosed and locked state, and the baffle 5 is in a position parallel to the surface of the carrier 1, and the matching portion 42 of the lock block 2 4 is located in the groove 5a of the baffle 5. When the binding 2 needs to be locked after passing through the tire a, it is only necessary to pass the locking shaft 8 from the clearance opening 1a to between the lock block 1 3 and the lock block 2 4. At this time, the control driving member 6 is operated, and the lock block 1 3 will slide toward the lock block 2 4 under the drive of the driving member 6 until the two are closed. After closing, the lock block 1 3 will continue to push the lock block 2 4 to slide together. At this time, the lock block 2 4 will push the baffle 5 to swing up while sliding until the baffle 5 and the tire a are tightly pressed against the limit position. At this time, the thrust of the driving member 6 on the lock block 1 3 keeps the locking shaft 8 in a locked state, as shown in FIG. Figure 4 As shown, the device is now in a locked and supported state. When unlocking is required, the driving member 6 is simply controlled to retract, and the lock block 1 3 is reset. The lock block 2 4 is automatically reset by the reset spring 9, and the baffle 5 is reset by self-reset. 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 the first embodiment, except that, in this embodiment, Figure 8 As shown, the baffle 5 is hinged on the locking block 2 4, and a lifting rod b is provided between the bottom of the baffle 5 and the locking block 1 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 1 3. The locking block 1 3 can push the baffle 5 to swing up by the lifting rod b.
