Abstract
Description
Technical Field
[0001] This utility model patent relates to the technical field of vehicle strapping, specifically to a vehicle strapping tightening and quick-release structure. Background Technology
[0002] When vehicles need to be transported or transferred, they are often fixed on transport racks, such as military tanks. The transport racks form transport vehicles, and the vehicles are fixed on the transport racks before being transported by the transport vehicles.
[0003] Currently, a load-bearing belt is generally used to connect to both the vehicle and the transport frame, securing the vehicle to the transport frame and preventing it from detaching during transport.
[0004] In the prior art, when a carrier belt is used to connect a vehicle and a transport frame, the carrier belt forms an enclosing section, which is connected to both the vehicle and the transport frame. When the enclosing section is needed to fix the vehicle to the transport frame, it needs to be shortened, and the enclosing section is in a tightened state. When it is needed to detach the vehicle from the transport frame, the enclosing section needs to be lengthened, and the enclosing section is in a quick-release state.
[0005] However, the current process of tightening or quickly releasing the carrying belt is too complicated, resulting in low operational efficiency. Utility Model Content
[0006] The purpose of this utility model is to provide a vehicle strapping and tightening and quick-release structure, which aims to solve the problem of cumbersome vehicle strapping and tightening or quick-release operations in the prior art.
[0007] This utility model is implemented as follows: a vehicle binding, tightening, and quick-release structure includes a connecting frame connected to a carrier belt; one end of the carrier belt has a fixed end, and the other end of the carrier belt has a free end; one end of the connecting frame has a fixed shaft, and the other end of the connecting frame has a rotating shaft; the fixed end is fixedly connected to the fixed shaft.
[0008] The rotating shaft is provided with an adjustment hole for the free end to pass through. When the free end passes through the adjustment hole, the carrying belt has an enclosing section that is connected to the vehicle and the transport frame respectively, and a free section that passes through the adjustment hole and is freely arranged. The enclosing section is formed between the fixed shaft and the rotating shaft.
[0009] The connecting frame is provided with a driving structure that drives the rotating shaft to rotate in the forward direction. When the driving structure drives the rotating shaft to rotate in the forward direction, the enclosing section and the free section are wrapped around the rotating shaft. The enclosing section is in a tightened state and the enclosing section is fixedly connected to the rotating shaft.
[0010] The connecting frame is provided with a limiting structure that restricts the rotation of the rotating shaft in the opposite direction. When the limiting structure is released from the restriction on the rotating shaft, the free section is pulled, and the rotating shaft rotates in the opposite direction. The enclosing section and the free section are released from the winding of the rotating shaft in the opposite direction, and the enclosing section is in a quick release state.
[0011] Furthermore, the connecting frame has two side plates arranged facing each other, the fixed shaft is arranged between the two side plates, and the two ends of the fixed shaft are fixedly connected to the side plates respectively; the rotating shaft is arranged parallel to the fixed shaft at intervals, and the adjusting hole extends along the axial direction of the rotating shaft.
[0012] Furthermore, the rotating shaft is arranged between the two side plates, with both ends of the rotating shaft movably passing through the side plates and rotatably connected to them. The rotating shaft has an extension that extends to the outside of the side plates, and the driving structure is connected to the extension.
[0013] Furthermore, the driving structure includes a ratchet disk sleeved on the outer extension and a swing frame that drives the ratchet disk to rotate in the forward direction. The outer extension is fixedly connected to the ratchet disk. The outer periphery of the ratchet disk is provided with multiple ratchet teeth, and there are tooth grooves between adjacent ratchet teeth. When the swing frame drives the ratchet disk to rotate in the forward direction, the rotating shaft rotates synchronously in the forward direction with the ratchet disk.
[0014] Furthermore, the swing frame is rotatably connected to the extension section, and the swing frame has an upper insert that is inserted into the tooth groove. When the swing frame swings in the opposite direction, the upper insert drives the ratchet disk to rotate in the opposite direction, and the rotating shaft rotates synchronously in the opposite direction with the ratchet disk.
[0015] Furthermore, the swing frame is provided with an upper movable frame that moves up and down. The bottom of the upper movable frame forms the upper insert. When the upper movable frame moves upward relative to the swing frame, the upper insert disengages from the tooth groove. When the upper movable frame moves downward relative to the swing frame, the upper insert is inserted into the tooth groove.
[0016] Furthermore, the swing frame is equipped with a torsion spring that drives the upper movable frame to move downwards and reset, and the torsion spring is connected to the upper movable frame.
[0017] Furthermore, the limiting structure includes a lower movable frame that moves back and forth relative to the connecting frame, the lower movable frame being movably connected to the connecting frame, and the lower movable frame having a lower insert.
[0018] When the lower movable frame moves forward relative to the connecting frame, the lower insert is inserted into the tooth groove, and the lower insert restricts the ratchet disc from rotating in the opposite direction; when the lower movable frame moves backward relative to the connecting frame, the lower insert disengages from the tooth groove.
[0019] Furthermore, the lower movable frame is connected to a spring that drives the lower movable frame to move forward and reset relative to the connecting frame.
[0020] Furthermore, the connecting frame is provided with an upper slot for the upper insert to be inserted. When the swing frame swings away from the connecting frame at a set angle, the upper insert is inserted into the upper slot, and the swing frame and the connecting frame are fixed relative to each other.
[0021] Compared with the prior art, the vehicle binding and quick-release structure provided by this utility model has the following advantages: when the free end passes through the rotating shaft, the carrying belt forms an enclosing section. The enclosing section is connected to the vehicle and the transport frame respectively. The rotating shaft is driven to rotate in the forward direction by the driving structure, so that the free section and the enclosing section are wrapped around the rotating shaft. The enclosing section is in a tightened state, realizing the binding and tightening of the vehicle. Secondly, the rotating shaft is restricted to rotate in the reverse direction by the limiting structure. When the limiting structure is released, the rotating shaft rotates in the reverse direction, and the enclosing section is released from the fixed connection with the rotating shaft. The enclosing section is in a quick-release state. The structure is simple, easy to bind and tighten or quickly release the vehicle, and has high operating efficiency. Attached Figure Description

[0030] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.
[0031] The vehicle binding, tightening, and quick-release structure includes a connecting frame 100 connected to a carrying belt 200. One end of the carrying belt 200 has a fixed end 201, and the other end of the carrying belt 200 has a free end. One end of the connecting frame 100 has a fixed shaft 102, and the other end of the connecting frame 100 has a rotating shaft 104. The fixed end 201 is fixedly connected to the fixed shaft 102.
[0032] The rotating shaft 104 is provided with an adjustment hole 105 for the free end to pass through. After the free end passes through the adjustment hole 105, the carrying belt 200 has an enclosing section 202 that is connected to the vehicle and the transport frame respectively, and a free section 203 that passes through the adjustment hole 105 and is freely arranged. The enclosing section 202 is formed between the fixed shaft 102 and the rotating shaft 104.
[0033] After the free end passes through the adjustment hole 105, it forms an enclosure section 202 between the fixed shaft 102 and the rotating shaft 104. The enclosure section 202 can be connected to the vehicle and the transport frame respectively. At this time, the connecting frame 100 is located in the middle of the enclosure section 202 and is used as the adjustment structure of the enclosure section 202. The free section 203 extends to the outside of the connecting frame 100 and is freely arranged.
[0034] The connecting frame 100 is equipped with a drive structure that drives the rotating shaft 104 to rotate in the forward direction. When the drive structure drives the rotating shaft 104 to rotate in the forward direction, the enclosing section 202 and the free section 203 are wound around the rotating shaft 104, and the enclosing section 202 is in a tightened state. The enclosing section 202 is fixedly connected to the rotating shaft 104. When the enclosing section 202 is fixedly connected to the rotating shaft 104, the length of the enclosing section 202 is not adjustable.
[0035] The connecting frame 100 is provided with a limiting structure that restricts the reverse rotation of the rotating shaft 104. When the limiting structure is released from the restriction on the rotating shaft 104, the free section 203 is pulled, the rotating shaft 104 rotates in the opposite direction, and the enclosing section 202 and the free section 203 are released from the winding of the rotating shaft 104 in the opposite direction. The enclosing section 202 is in a quick release state.
[0036] The vehicle binding and quick-release structure provided above, after the free end passes through the rotating shaft 104, the carrying belt 200 forms an enclosing section 202. The enclosing section 202 is connected to the vehicle and the transport frame respectively. The rotating shaft 104 is driven to rotate in the forward direction by the driving structure, so that the free section 203 and the enclosing section 202 are wrapped around the rotating shaft 104. The enclosing section 202 is in a tightened state, realizing the binding and tightening of the vehicle. Secondly, the rotating shaft 104 is restricted to rotate in the reverse direction by the limiting structure. When the limiting structure is released, the rotating shaft 104 rotates in the reverse direction, and the enclosing section 202 is released from the fixed connection with the rotating shaft 104. The enclosing section 202 is then in a quick-release state. The structure is simple, easy to bind and tighten or quickly release the vehicle, and has high operating efficiency.
[0037] In this embodiment, the connecting frame 100 has two side plates 101 arranged facing each other, and a fixing shaft 102 is arranged between the two side plates 101. The two ends of the fixing shaft 102 are fixedly connected to the side plates 101 respectively. This facilitates the connection between the fixing end 201 and the fixing shaft 102.
[0038] In this embodiment, the rotating shaft 104 is arranged between two side plates 101. The two ends of the rotating shaft 104 respectively pass through the side plates 101 and are rotatably connected to the side plates 101. The rotating shaft 104 has an extension portion extending to the outside of the side plates 101, and the extension portion 1041 is connected to the driving structure.
[0039] In this embodiment, the rotating shaft 104 and the fixed shaft 102 are arranged parallel to each other at intervals, and the adjusting hole 105 extends along the axial direction of the rotating shaft 104. Generally, the carrying belt 200 is flat, and the adjusting hole 105 extends along the axial direction of the rotating shaft 104, which facilitates the free end of the carrying belt 200 to pass through the adjusting hole 105 and facilitates the pulling of the carrying belt 200 in the adjusting hole 105.
[0040] In this embodiment, the driving structure includes a ratchet disk 300 sleeved on the extension section 1041 and a swing frame 400 that drives the ratchet disk 300 to rotate in the forward direction. The extension section 1041 is fixedly connected to the ratchet disk 300. The outer periphery of the ratchet disk 300 is provided with a plurality of ratches 301, and there are tooth grooves 302 between adjacent ratches 301. When the swing frame 400 drives the ratchet disk 300 to rotate in the forward direction, the rotating shaft 104 rotates synchronously in the forward direction with the ratchet disk 300.
[0041] The outer extension 1041 is fixedly connected to the ratchet disk 300, so that the rotating shaft 104 is integrated with the ratchet disk 300, and the two rotate synchronously in the forward or reverse direction. The swing of the swing frame 400 drives the ratchet disk 300 to rotate, thereby realizing the rotation of the rotating shaft 104.
[0042] Of course, since the ratchet 301 is arranged at an angle on the ratchet disk 300, when the swing frame 400 swings forward, it can drive the ratchet disk 300 and the rotating shaft 104 to swing forward synchronously. When the swing frame 400 swings in the opposite direction, the swing frame 400 swings in the opposite direction relative to the ratchet disk 300. At this time, the ratchet disk 300 and the rotating shaft 104 are in a stationary state.
[0043] Once the limiting structure is released from the restriction on the rotating shaft 104, pulling the free section 203 can drive the rotating shaft 104 and the ratchet disk 300 to rotate in the opposite direction.
[0044] In this embodiment, the swing frame 400 is rotatably connected to the extension section 1041. The swing frame 400 has an upper insert 402 inserted into the tooth groove 302. When the swing frame 400 swings forward, the upper insert 402 drives the ratchet disk 300 to rotate forward, and the rotating shaft 104 rotates forward synchronously with the ratchet disk 300.
[0045] When the swing frame 400 swings in the opposite direction, the upper insert 402 slips against the ratchet 301 of the ratchet disk 300 and does not drive the ratchet disk 300 to rotate in the opposite direction.
[0046] In this embodiment, the swing frame 400 is provided with an upper movable frame 401 that moves up and down. An upper insert 402 is formed at the bottom of the upper movable frame 401. When the upper movable frame 401 moves upward relative to the swing frame 400, the upper insert 402 disengages from the toothed groove 302. When the upper movable frame 401 moves downward relative to the swing frame 400, the upper insert 402 is inserted into the toothed groove 302.
[0047] In this way, when the ratchet 300 and the rotating shaft 104 need to rotate in the forward direction, the upper movable frame 401 moves downward relative to the swing frame 400, the upper insert 402 is inserted into the tooth groove 302, and the swing frame 400 swings in the forward direction, which can drive the ratchet 300 and the rotating shaft 104 to rotate in the forward direction synchronously.
[0048] When the ratchet disc 300 and the rotating shaft 104 need to rotate in opposite directions, firstly, the upper movable frame 401 moves upward relative to the swing frame 400, and the upper insert 402 disengages from the tooth groove 302, so as not to interfere with the ratchet disc 300, and the limiting structure is freed from the restriction on the rotating shaft 104. In this way, the free section 203 can be pulled, and the free section 203 can be used to drive the rotating shaft 104 to rotate in the opposite direction.
[0049] In this embodiment, the swing frame 400 is provided with a torsion spring that drives the upper movable frame 401 to move downward and reset. The torsion spring is connected to the upper movable frame 401, which facilitates the downward movement and reset of the upper movable frame 401.
[0050] In this embodiment, the limiting structure includes a lower movable frame 103 that moves back and forth relative to the connecting frame 100. The lower movable frame 103 is movably connected to the connecting frame 100 and has a lower insert 1031. When the lower movable frame 103 moves forward relative to the connecting frame 100, the lower insert 1031 is inserted into the tooth groove 302, and the lower insert 1031 restricts the ratchet disc 300 from rotating in the opposite direction. When the lower movable frame 103 moves backward relative to the connecting frame 100, the lower insert 1031 disengages from the tooth groove 302.
[0051] In this way, when the lower insert 1031 is inserted into the tooth groove 302, it will not interfere with the forward rotation of the ratchet disk 300, and will restrict the reverse rotation of the ratchet disk 300, which in turn restricts the reverse rotation of the rotating shaft 104.
[0052] In this embodiment, a spring 1032 is connected to the lower movable frame 103 to drive the lower movable frame 103 to move forward relative to the connecting frame 100 and reset, so that the lower movable frame 103 can swing downward and reset.
[0053] In this embodiment, the connecting frame 100 is provided with an upper slot 106 for the upper insert 402 to be inserted. When the swing frame 400 swings away from the connecting frame 100 at a set angle, the upper insert 402 is inserted into the upper slot 106, and the swing frame 400 and the connecting frame 100 are fixed relative to each other.
[0054] In this way, when the enclosing section 202 is in a tightened state and the set tightening force is reached, and it is no longer necessary to use the swing frame 400 to drive the ratchet disc 300, the upper insert 402 can be disengaged from the tooth groove 302. After the swing frame 400 swings relative to the connecting frame 100 at a set angle, the upper insert 402 is embedded in the upper slot 106. At this time, the swing frame 400 is fixedly connected to the connecting frame 100 as a whole.
[0055] When the upper insert 402 is inserted into the upper slot 106, the swing frame 400 and the connecting frame 100 are kept in opposite directions, and the swing frame 400 and the connecting frame 100 are in an open state.
[0056] The connecting frame 100 is provided with an upper insert 402 for insertion into the lower slot 107. When the swing frame 400 rotates in the opposite direction to the connecting frame 100 by a set angle, the connecting frame 100 and the swing frame 400 are stacked together facing each other, the upper insert 402 is inserted into the lower slot 107, and the swing frame 400 and the connecting frame 100 are fixed relative to each other. At this time, the swing frame 400 and the connecting frame 100 are arranged facing each other and are in a stacked state.
[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
