In addition, the translation push rod 41 is arranged along the center axis of the vehicle 1, and the pull rod 42 is installed on the push rod shaft of the translation push rod 41, so that the push rod shaft of the translation push rod 41 can drive the pull rod 42 to make reciprocating motion along the center axis of the vehicle 1, thereby providing power for subsequent pushing of the cage rack 2 from the front to the tail of the vehicle or pulling of the cage rack 2 from the tail to the front of the vehicle.

[0039] Figure 5 The structure diagram of the cage rack of a preferred embodiment of the utility model. As shown in Figure 1 , Figure 2 and Figure 5As shown, the cage frame 2 further comprises a frame body 21, a front wheel set 22, a clamping sleeve 23, a front clamping plate 24, a rear clamping plate 25 and a rear wheel set 26. At this time, the front wheel set 22 and the rear wheel set 26 are arranged at the front and middle tail of the bottom of the frame body 21 respectively, and the front wheel set 22 and the rear wheel set 26 provide support for the translation of the cage frame 2 on the cargo area of the vehicle 1, which is more labor-saving and avoids structural wear and tear during translation, prolonging the service life of the structure. In addition, the clamping sleeve 23 is arranged at the middle front of the bottom of the frame body 21, and a downward clamping hole 231 is formed in the clamping sleeve 23, and the clamping hole 231 is connected or disconnected with the pull rod 42, that is, when the cage frame 2 needs to cooperate with the translation assembly 4, the clamping sleeve 23 at the bottom of the frame body 21 is clamped with the pull rod 42 installed on the push rod shaft of the translation push rod 41 through the clamping hole 231, and the cage frame 2 is driven by the translation push rod 41 to move horizontally along the central axis of the vehicle 1 on the vehicle 1. In addition, the front clamping plate 24 and the rear clamping plate 25 are arranged at the middle tail of the bottom of the frame body 21, and the front clamping plate 24 and the rear clamping plate 25 are arranged on the central axis of the frame body 21. The front clamping plate 24 and the rear clamping plate 25 are arranged separately at the bottom of the frame body 21, which adapts to the state that the front clamping groove 311 and the rear clamping groove 312 are arranged separately on the turnover plate 31. In addition, the front clamping plate 24 and the rear clamping plate 25 are clamped into or separated from the front clamping groove 311 and the rear clamping groove 312 respectively, that is, when the cage frame 2 needs to cooperate with the turnover assembly 3, the front clamping plate 24 and the rear clamping plate 25 at the bottom of the frame body 21 are clamped into the front clamping groove 311 and the rear clamping groove 312 on the turnover plate 31 respectively, so that the turnover plate 31 can drive the cage frame 2 to overturn.It is worth pointing out that when the terminal position of the cage frame 2 is driven by the turnover assembly 3 from the vertical state to the horizontal state, the sleeve 23 is just at the farthest position of the movement stroke of the pull rod 42 driven by the translation push rod 41, that is, when the turnover process is just completed, the sleeve 23 just cooperates with the pull rod 42 to realize the connection of the translation assembly 4 and the cage frame 2, and at the first time when the pull rod 42 horizontally pulls the cage frame 2 to move towards the vehicle head, the front clamping plate 24 and the rear clamping plate 25 are just separated from the turnover front clamping groove 311 and the turnover rear clamping groove 312 to realize the disconnection of the cage frame 2 and the turnover assembly 3, and vice versa, when the cage frame 2 is translated by the translation push rod 41 from the vehicle head to the terminal position in the direction of the vehicle tail, the front clamping plate 24 and the rear clamping plate 25 are just clamped into the turnover front clamping groove 311 and the turnover rear clamping groove 312 to realize the connection of the cage frame 2 and the turnover assembly 3, and at the first time when the cage frame 2 is driven by the turnover assembly 3 from the horizontal state to the vertical state, the sleeve 23 is separated from the pull rod 42 to realize the disconnection of the cage frame 2 and the translation assembly 4, so as to ensure that the driving of the cage frame 2 by the turnover assembly 3 and the translation assembly 4 is independent and will not interfere with each other, so that the turnover assembly 3 and the translation assembly 4 can be independently installed on the vehicle 1 without stacking arrangement, thereby avoiding the problems of heavy burden of the lower assembly caused by the stacking arrangement and unstable operation of the upper assembly caused by the stacking arrangement, and further avoiding the problem of complex structure caused by setting more linkage structures between the turnover assembly 3 and the translation assembly 4 to limit the related movement, so that the overall structure is simpler, the manufacturing and using costs are lower, and the large-scale popularization and use demand is met.

[0040] Specifically, the slot-shaped guide rail 11 is arranged on the vehicle 1 along the axial direction, and when the cage frame 2 is in the horizontal state on the vehicle 1, the front wheel set 22 and the rear wheel set 26 at the bottom of the frame body 21 are clamped into and slide in the grooves of the slot-shaped guide rail 11, that is, the slot-shaped guide rail 11 guides the translation of the cage frame 2 and limits the lateral movement of the cage frame 2, thereby improving the stability of the cage frame 2. Alternatively, when the cage frame 2 is turned relative to the vehicle 1, the front wheel set 22 and the rear wheel set 26 at the bottom of the frame body 21 are out of the grooves of the slot-shaped guide rail 11, thereby meeting the turnover requirement of the cage frame 2.

[0041] Figure 6 The cooperation of the cooperation clamping groove and the fixed lower clamping groove of the preferred embodiment of the utility model is shown in the figure. Figure 7 The enlarged schematic view of the cooperation of the turnover assembly and the cage frame of the preferred embodiment of the utility model is shown in the figure. Figure 1 、 Figure 2 and Figure 6 and Figure 7As shown, the bottom of the frame body 21 of the cage frame 2 is also provided with a matching clamping groove 27, and the slot of the matching clamping groove 27 is arranged towards the side of the vehicle head, and the vehicle 1 is also provided with a fixed lower clamping groove 12, and the slot of the fixed lower clamping groove 12 is arranged towards the vehicle tail direction, when the cage frame 2 translates along the center axis of the vehicle 1, the matching clamping groove 27 and the fixed lower clamping groove 12 are close or far away, realize the mutual clamping or separation of the matching clamping groove 27 and the fixed lower clamping groove 12, that is, when the cage frame 2 translates along the center axis of the vehicle 1 and moves from the vehicle tail to the vehicle head side, the matching clamping groove 27 can be clamped into the fixed lower clamping groove 12, meet the use requirement that the cage frame 2 is stably connected on the vehicle 1 after translation, and when the cage frame 2 translates along the center axis of the vehicle 1 and moves from the vehicle head to the vehicle tail side, the matching clamping groove 27 can be separated from the fixed lower clamping groove 12, which provides conditions for subsequent cage frame 2 to be turned over. Preferably, the matching clamping groove 27 comprises a matching front clamping groove and a matching rear clamping groove, and the matching front clamping groove and the matching rear clamping groove are respectively arranged at both ends of the frame body 21, and the frame body 21 is provided with two matching front clamping grooves and two matching rear clamping grooves, the two matching front clamping grooves are respectively arranged on both sides of one end of the frame body 21, and the two matching rear clamping grooves are respectively arranged on both sides of the other end of the frame body 21, and the vehicle 1 is provided with a fixed lower clamping groove 12 corresponding to each matching front clamping groove and each matching rear clamping groove, so that the cage frame 2 can be more stably limited on the vehicle 1 during transportation.

[0042] More specifically, the bottom groove wall of the matching clamping groove 27 and the top groove wall of the fixed lower clamping groove 12 are both arranged as inclined surfaces, and when the matching clamping groove 27 and the fixed lower clamping groove 12 are mutually clamped, the bottom groove wall of the matching clamping groove 27 and the top groove wall of the fixed lower clamping groove 12 abut each other, so that the bottom of the matching clamping groove 27 and the top of the fixed lower clamping groove 12 are both wedge-shaped structures, so that when the matching clamping groove 27 and the fixed lower clamping groove 12 are mutually matched, as the cage frame 2 moves towards the vehicle head direction under the action of the translation assembly 4, the top groove wall of the fixed lower clamping groove 12 can exert a downward pulling force on the bottom groove wall of the matching clamping groove 27 and the pulling force gradually increases, so that the fixed lower clamping groove 12 and the matching clamping groove 27 are clamped more tightly, and when the translation assembly 4 does not reversely push the cage frame 2 to move, the pulling force will always exist, so that the cage frame 2 can be more stably installed on the cargo area of the vehicle 1, avoiding upward movement of the cage frame 2, reducing vibration, and improving transportation stability.

[0043] Figure 8 It is a zoomed schematic view of the translation assembly of the preferred embodiment of the utility model and the cage frame. As shown in Figure 1 , Figure 2 and Figure 8As shown in the drawings, the translation assembly 4 further comprises a support bar 43, at this time, the support bar 43 is arranged parallel to the push rod shaft of the translation push rod 41, so that the arrangement direction of the support bar 43 is the moving direction of the pull rod 42, and the pull rod 42 is slidingly arranged on the support bar 43, so that the support bar 43 provides support and guidance for the pull rod 42, thereby improving the stability of the pull rod 42 during movement. Preferably, the support bar 43 is arranged on both sides of the push rod shaft of the translation push rod 41, and the two ends of the pull rod 42 are slidingly arranged on the support bars 43 on both sides, thereby achieving support for the pull rod 42 and improving the stability of the pull rod 42 during movement.

[0044] Figure 9 It is a structure diagram of the pull rod of a preferred embodiment of the utility model. As shown in Figure 1 、 Figure 2 and Figure 8 and Figure 9 shown, the pulley 421 is also installed on the pull rod 42, and when the pull rod 42 cooperates with the support bar 43, the pulley 421 on the pull rod 42 is rollingly installed on the corresponding support bar 43. It is worth pointing out that when the support bar 43 is arranged at both ends of the pull rod 42, the pulley 421 is installed at both ends of the pull rod 42, and the wheel surface of the pulley 421 is in contact with the support bar 43 on the corresponding side. By using the pulley 421 as the structure for the pull rod 42 to contact the support bar 43, the wear problem of the pull rod 42 during movement on the support bar 43 can be effectively reduced, thereby prolonging the service life.

[0045] More specifically, the barb 431 is further arranged on the support bar 43 and located at one end close to the tail of the vehicle, and the opening of the barb 431 is arranged towards the side of the vehicle head, so that when the pull rod 42 moves towards the maximum stroke in the direction of the vehicle tail following the movement of the push rod shaft of the translation push rod 41, the pull rod 42 is clamped into the barb 431, thereby preventing the translation push rod 41 from being bent and affecting the use performance or causing damage. Alternatively, when the pull rod 42 moves towards the vehicle head, the pull rod 42 can be pulled out of the barb 431, at this time, the cage frame 2 has been separated from the turnover assembly 3, and the pull rod 42 will not be pulled upwards any more, thereby meeting the horizontal movement requirement of the pull rod 42.

[0046] Figure 10 It is an installation schematic view of the wheel sleeve, the fixing plate and the roller of the turnover assembly of a preferred embodiment of the utility model. As shown in Figure 1 、 Figure 2 and Figure 3 and Figure 10As shown, the turnover assembly 3 further comprises a turnover wheel set 33, and due to the cooperation between the turnover front clamping groove 311 and the turnover rear clamping groove 312 on the turnover plate 31 and the front clamping plate 24 and the rear clamping plate 25 on the cage frame 2 during the turnover process, there is still an open freedom between the two, that is, the cage frame 2 can still be separated from the turnover plate 31 along the opening direction of the turnover front clamping groove 311 and the turnover rear clamping groove 312 during the turnover process, at this time, the last separation direction of the cage frame 2 can be limited by the turnover wheel set 33, so that the cage frame 2 can be more stable during the turnover process.

[0047] More specifically, the turnover wheel set 33 further comprises a wheel sleeve 331, a fixed plate 332 and a roller 333, and during installation, the fixed plate 332 is installed on the frame body 21, and the roller 333 is rotatably installed on the fixed plate 332, that is, the roller 333 is stably installed on the frame body 21 through the fixed plate 332. In addition, the wheel sleeve 331 is installed at the tail of the vehicle 1, and a U-shaped opening is formed on the wheel sleeve 331 and faces the head direction. At this time, when the cage frame 2 moves along the central axis of the vehicle 1 from the head to the tail to the terminal position, the roller 333 which moves integrally with the cage frame 2 can smoothly enter the U-shaped opening.
