In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0043] This utility model relates to a vehicle body locking device for locking a vehicle body onto a skid for transportation. The mounting base 1 of this locking device rotatably mounts a locking shaft 2. After the clamping block 23 passes through the locking hole 8 of the vehicle body and rotates, the vehicle body is locked. An elastic limiting member 11 abuts against a first limiting surface 21 before the locking shaft 2 locks the vehicle body, thus limiting the rotation of the locking shaft 2; and abuts against a second limiting surface 22 after the locking shaft 2 locks the vehicle body, further limiting the rotation of the locking shaft 2. This prevents the locking shaft 2 from slipping and rotating, and keeps the angular position of the locking shaft 2 relatively fixed in the unlocked state (i.e., when the vehicle body is not locked). It can pass through the locking hole 8 of the vehicle body, solving the problem of not being able to simultaneously prevent slippage and rotation of the eccentric structure before and after locking the vehicle body.

[0044] A vehicle body locking device, specifically, such as Figures 1-8 As shown, the device includes a mounting base 1, a locking shaft 2, and a rotating arm 3. The mounting base 1 is fixed with an elastic limiting member 11 and a mounting hole 13 penetrating the mounting base 1. The locking shaft 2 is hinged in the mounting hole 13. The locking shaft 2 includes a first limiting surface 21 and a second limiting surface 22 exposed outside the mounting hole 13. The first limiting surface 21 and the second limiting surface 22 are respectively used to cooperate with the elastic limiting member 11 to restrict the locking shaft 2 from slipping and rotating before and after the locking shaft 2 switches to the locked state. Due to its elasticity, the elastic limiting member 11 can produce a certain limiting and anti-rotation effect on the locking shaft 2. When sufficient external force is applied, the locking shaft 2 can break through the limiting and anti-rotation effect of the elastic limiting member 11 and rotate. The locking shaft 2 is fixed with a pressing block 23 that forms an eccentric structure with the locking shaft 2 and an axial limiting member 24 for abutting against the mounting base 1. The rotating arm 3 is fixed at the end of the locking shaft 2 away from the pressing block 23 and is used to drive the locking shaft 2 to rotate around its own axis. The locking shaft 2 includes a locked state and an unlocked state. In the initial state (unlocked state), the clamping block 23 can pass through the locking hole 8 of the vehicle body. After the locking shaft 2 rotates, the clamping block 23 rotates with it and hooks the vehicle body to the upper limit position in the vertical direction, thereby locking the vehicle body onto the skid.

[0045] In one embodiment, such as Figures 1-3As shown, the elastic limiting piece 11 includes a spring sheet fixed at one end on the mounting seat 1; the locking shaft 2 includes a cylindrical anti-rotation segment 20, which includes first limiting surfaces 21 and second limiting surfaces 22 on both sides; the spring sheet is adapted to abut against the first limiting surfaces 21 and the second limiting surfaces 22 before and after the locking shaft 2 is switched to the locked state.

[0046] Based on the fact that the locking shaft 2 includes the anti-rotation segment 20, as shown in Figure 2 As shown, the mounting seat 1 includes two vertically opposite mounting holes 13; the locking shaft 2 is rotatably arranged through the two mounting holes 13, and the anti-rotation segment 20 is exposed between the two mounting holes 13. By means of the two opposite mounting holes 13 of the mounting seat 1, the stability of the locking shaft 2 during rotation is increased, and deviation of the rotating swing arm 3 from driving the locking shaft 2 to rotate is prevented.

[0047] In some preferred embodiments, as shown in Figure 2 As shown, the mounting seat 1 includes a bottom plate, a connecting plate arranged on the bottom plate, and a mounting sleeve 12 arranged on the connecting plate as an inner cavity serving as the mounting hole 13; the bottom plate also has the mounting hole 13 corresponding to the mounting sleeve 12; and the support plate 14 is fixed on the connecting plate.

[0048] Based on the fact that the locking shaft 2 includes the anti-rotation segment 20, as shown in Figures 2-3 As shown, the anti-rotation segment 20 includes a quadrangular prism; the quadrangular prism includes two first limiting surfaces 21 and two second limiting surfaces 22 opposite to each other; and the mounting seat 1 has spring sheets fixed on both sides. The quadrangular prism is used as the anti-rotation segment 20, two groups of first limiting surfaces 21 and second limiting surfaces 22 are achieved, the spring sheets arranged on both sides of the mounting seat 1 can correspond to the two groups of first limiting surfaces 21 and second limiting surfaces 22, and the anti-rotation limiting effect before and after locking is improved.

[0049] Preferably, the four peripheral angles of the quadrangular prism are in the form of circular arcs, so as to avoid sharp peripheral angles from scratching the spring sheets and intensifying abrasion and noise of the spring sheets.

[0050] In some embodiments, as shown in Figure 2 As shown, the locking device further includes a support plate 14 fixed on the mounting seat 1, and the top surface of the support plate 14 has a gap with the pressing block 23 for supporting and supporting the vehicle body, the skid has an upward supporting effect on the vehicle body, and the locking is achieved by means of the pressing block 23 hooking the vehicle body; the support plate 14 supports the vehicle body when the locking shaft 2 locks the vehicle body, thereby enhancing the stability of the vehicle body locked on the skid.

[0051] In some embodiments, as shown in Figure 2 As shown, the axial limiting piece 24 includes a limiting plate fixed on the top surface of the locking shaft 2 and abutting against the mounting seat 1. The limiting plate is simple in structure, can abut against the mounting seat 1 to limit the upward movement of the locking shaft 2, and achieves locking of the vehicle body on the skid.

[0052] In some embodiments, as shown inFigures 4-5 As shown, the locking device further comprises a driving device abutting the rotating swing arm 3, for driving the locking shaft 2 to break through the limiting action of the elastic limiting member 11 and rotate along the axial direction of the locking shaft 2 through the rotating swing arm 3. By driving the locking shaft 2 to rotate through the driving device, the vehicle body is locked, avoiding manual rotation of the locking shaft 2 to lock the vehicle body, thereby reducing efficiency and wasting manpower

[0053] Based on the fact that the locking device further comprises a driving device, as Figures 4-5 As shown, the driving device comprises a motor 4 and a transmission member 5 eccentrically arranged on the output shaft of the motor 4. When the output shaft of the motor 4 rotates, the transmission member 5 rotates around the locking shaft 2 and abuts to drive the rotating swing arm 3 to rotate around the locking shaft 2. In the locked state, the transmission member 5 does not hinder the movement of the rotating swing arm 3 along the movement direction of the skid. Preferably, the rotating swing arm 3 is arranged along the movement direction of the vehicle body in the locked state, and the rotating swing arm 3, the locking shaft 2 and the pressing block 23 are perpendicular to each other. The motor 4 drives the transmission member 5 to rotate around the locking shaft 2, which can abut to drive the rotating swing arm 3 to rotate. Through the abutting mode, the locking shaft 2 and the transmission member 5 can be separated, avoiding interference between the skid and the motor 4 and its transmission member 5 when the skid moves after being locked.

[0054] Based on the fact that the motor 4 is provided with the transmission member 5, as Figure 5 As shown, the transmission member 5 comprises a stand column eccentrically and fixedly arranged on the output shaft of the motor 4 and a sleeve 51 arranged on the stand column. When the motor 4 rotates, the sleeve 51 abuts the rotating swing arm 3 to rotate around the stand column, which can drive the rotating swing arm 3 to rotate and prevent the sleeve 51 from generating noise by rubbing against the rotating swing arm 3.

[0055] Based on the fact that the motor 4 is provided with the transmission member 5, as Figure 6 As shown, the motor 4 is drivingly connected with at least one rotatable transmission shaft assembly 6, and the transmission shaft assembly 6 is eccentrically provided with the transmission member 5, which is used to drive at least one locking shaft 2 to rotate. When the motor 4 is directly installed through the transmission shaft assembly 6 to realize the rotation of the locking shaft 2, it is not convenient due to the small space beside the skid. Multiple transmission shaft assemblies 6 can be used to drive multiple locking shafts 2 to rotate to realize the locking of the vehicle body, thereby improving the efficiency.

[0056] In a preferred embodiment, as Figure 6 As shown, the motor 4 is arranged on the fixed frame, and the transmission shaft assembly 6 is arranged on the upper side of the fixed frame and extends to one side of the vehicle body. The motor 4 drives the transmission shaft assembly 6 to rotate on the fixed frame through the transmission belt 7. Preferably, two transmission shaft assemblies 6 are arranged, and the output shaft of the motor 4 forms a triangular structure with the two transmission shaft assemblies 6 through the transmission belt 7. The transmission belt 7 can be a chain meshing with the output shaft of the motor 4, and the transmission shaft assembly 6 is provided with a gear meshing with the chain.

[0057] Based on the fact that the motor 4 is drivingly connected with the transmission shaft assembly 6, as Figures 5-6As shown, the transmission rotating shaft assembly 6 comprises a fixed shaft, a rotating sleeve 61 sleeved on the fixed shaft and capable of rotating around the fixed shaft, and a mounting plate 62 fixed on the rotating sleeve 61; the transmission member 5 is arranged on the mounting plate 62 and is eccentric to the fixed shaft. Optionally, the fixed shaft is vertically fixed on the fixed frame, one end of the mounting plate 62 is fixed on the rotating sleeve 61, and the other end is provided with the transmission member 5; specifically, a stand is fixed on the other end of the mounting plate 62, the sleeve pipe 51 is arranged on the stand, and a limiting block 52 limiting the sleeve pipe 51 is detachably arranged at the end of the stand. The transmission rotating shaft assembly 6 has a simple structure, the mounting plate 62 is fixed on the fixed shaft through the rotating sleeve 61, the transmission member 5 can be eccentrically arranged, the transmission member 5 can rotate around the locking shaft 2, so as to drive the rotating swing arm 3 to rotate and realize the locking of the vehicle body.

[0058] In actual use, the mounting sleeve 12 is fixed on one side of the mounting seat 1 to form a mounting hole 13, and the bottom plate is also provided with a mounting hole 13 corresponding to the mounting sleeve 12; in the unlocking state of the locking shaft 2, the elastic sheet abuts against the first limiting surface 21 to prevent the locking shaft 2 from slipping and rotating, after the pressing block 23 passes through the locking hole 8 of the vehicle body, the motor 4 drives the transmission rotating shaft assembly 6 to rotate, the transmission member 5 rotates axially on the transmission rotating shaft assembly 6 around the locking shaft 2, in the rotation of the transmission member 5, the sleeve pipe 51 abuts against the rotating swing arm 3 to rotate on the stand, and at the same time, the locking shaft 2 is driven to rotate through the rotating swing arm 3, the pressing block 23 rotates with the locking shaft 2 to be in the state of pressing the vehicle body, the supporting plate 14 abuts against the vehicle body, the elastic sheet abuts against the second limiting surface 22 to prevent the locking shaft 2 from slipping and rotating, and the rotating swing arm 3 is in the state of being parallel to the running direction of the vehicle body, so that the skid can be directly moved.
