[0022] Figures 1 to 5 is the best embodiment of the present utility model. The following will further explain the present utility model in conjunction with the attached Figures 1 to 5 drawings.

[0023] As Figures 1 - 2 shown, a sliding tray of the present utility model includes a fixed chassis, a tray, a rotating member, an operating handle and a limiting mechanism. The tray is slidably arranged in the fixed chassis. The rotating member is rotatably arranged at the bottom of the tray. The operating handle is telescopically arranged at the pulling-out end of the tray. The telescopic end of the operating handle is connected to one end of the rotating member through a pull rod 6. The limiting mechanism is connected to the other end of the rotating member. The limiting mechanism passes through the side of the tray. A plurality of positioning holes 18 are provided on the side of the fixed chassis. The pull rod 6 pulls the rotating member to drive the limiting mechanism to be insertably arranged in the positioning holes 18 on the side of the fixed chassis. The setting direction of the pull rod 6 is perpendicular to the setting direction of the limiting mechanism.

[0024] In this embodiment, the rotating member is a rotating adjustment plate 3 in the shape of a right triangle, with holes opened on each angular bisector. The right-angled end is rotatably connected to the bottom of the tray, and the two acute-angled ends are respectively rotatably connected to the pull rod 6 and the limit pin 12, playing a role in adjusting and transmitting force during the operation. A limit seat is also provided at the connection with the bottom of the tray, and the limit seat is arranged on one side of the rotating adjustment plate 3. In this embodiment, the limit seat is L-shaped. After the rotating adjustment plate 3 rotates, its side contacts the L-shaped limit seat to prevent the gear adjustment plate 3 from moving significantly.

[0025] The limiting mechanism includes a limit pin 12 and a limit sleeve 13 fixed to the side of the tray. The diameter of the end of the limit pin 12 is smaller than the inner diameter of the limit sleeve 13, enabling it to have a certain radial movement space while telescoping in the limit sleeve 13. Positioning holes 18 are provided on the side of the fixed chassis. One end of the limit pin 12 is connected to the end of the rotating member, and the other end passes through the limit sleeve 13 and is insertably arranged in the positioning holes 18. In this embodiment, when sliding the tray, when the positioning hole 18 on the side of the fixed chassis passes by the limit pin 12, the limit pin 12 automatically inserts into the positioning hole 18. By setting different positioning holes 18 at intervals on the fixed chassis, the pulling-out length of the tray is restricted to meet different usage requirements.

[0026] Furthermore, the operating handle includes a locking link 7 and a locking handle 8. One end of the pull rod 6 is rotatably connected to the rotary adjusting plate 3, and the other end is rotatably connected to the locking link 7. The locking link 7 extends out of the fixed chassis and is connected to the locking handle 8. A spring 4 is sleeved on the pull rod 6. One end of the spring 4 close to the locking link 7 is fixedly connected to the tray, and the other end is fixedly connected to the pull rod 6. During the locking process, the spring 4 plays a role in buffering and resetting. Pull the locking handle 8, pull the pull rod 6 through the locking link 7, the pull rod 6 drives the rotary adjusting plate 3 to rotate and the limit pin 12 disengages from the positioning hole 18, so that the tray can be slid. When the locking handle 8 is released, the spring 4 resets the pull rod 6, and the limit pin 12 is inserted into the positioning hole 18, and the tray is locked in place to prevent accidental sliding.

[0027] In this embodiment, two locking links 7 are arranged side by side. The fixed ends of the two locking links 7 are respectively connected to both ends of the locking handle 8, and the telescopic ends of the two locking links 7 are connected to the pull rod 6 through a push plate 20. The pull rod 6 is fixedly connected to the center of the push plate 20.

[0028] The tray includes tray longitudinal beams 5, tray cross beams 11 and a tray board 19. Articles are placed on the tray board 19. A number of tray cross beams 11 are arranged between the tray longitudinal beams 5, and the tray board 19 is fixed on the upper sides of the tray longitudinal beams 5 and the tray cross beams 11. Guide sleeves are provided on the tray cross beams 11, and the pull rod 6 is arranged on the tray cross beams 11 through the guide sleeves.

[0029] See Figures 3 - 4 , the fixed chassis includes a chassis main body 1, and chassis chutes 2 are arranged inside both sides of the chassis main body 1. A number of positioning holes 18 are opened on the sides of the chassis chutes 2 to provide tracks and positioning points for the sliding and limiting of the tray. A baffle 17 is provided at the end of the chassis main body 1, and a rubber buffer pad 16 is arranged on the inner side of the baffle 17 to prevent the tray from sliding out excessively and play a buffering role, improving the use safety. Reinforcing ribs are also provided on the chassis main body 1 to enhance the strength of the fixed chassis.

[0030] A number of rollers 15 are symmetrically arranged on both sides of the pallet longitudinal beam 5, and the rollers 15 are arranged in the chassis chute 2. In this embodiment, rollers 15 are provided at both ends of both sides of the pallet longitudinal beam 5 at the other end relative to the pulling end of the pallet longitudinal beam 5. When the pallet longitudinal beam 5 is pulled out to the extreme position, the center of gravity of the pallet longitudinal beam 5 will shift towards the pulling end of the pallet longitudinal beam 5. At this time, affected by gravity, the pallet longitudinal beam 5 presses down, and the rollers 15 at the other end of the pallet longitudinal beam 5 lift up to contact the upper track of the chassis chute 2, which can prevent the pallet from moving further. Side wheels 14 are also provided on the side of the pallet longitudinal beam 5. The axis of the side wheel 14 is perpendicular to the axis of the roller 15, and the side wheel 14 prevents the pallet from swaying left and right and rubbing against the fixed chassis when sliding. A number of support beams 10 perpendicular to the pallet cross beam 11 are also provided between the pallet cross beams 11 to enhance the load-bearing capacity of the pallet. In this embodiment, a handle 9 is also provided at the pulling end of the pallet longitudinal beam 5 to facilitate the pulling of the pallet longitudinal beam 5.

[0031] Combined with Figure 4 、 5 When the present utility model is in use, the user pulls the pallet through the handle 9 and the locking handle 8. Under the action of the rollers 15 and the side wheels 14, the pallet slides smoothly along the chassis chute 2 of the fixed chassis. During the sliding process, the limit pin 12 sequentially passes through a number of positioning holes 18 on the side of the fixed chassis. When the locking handle 8 is released, the spring 4 drives the rotary adjusting plate 3 to rotate through the pull rod 6, and inserts the limit pin 12 into the positioning hole 18 at the required position, and the pallet is locked. When it is necessary to adjust the position of the pallet again or close the pallet, only need to pull the locking handle 8, the pull rod 6 drives the rotary adjusting plate 3 to rotate in the reverse direction, the limit pin 12 disengages from the positioning hole 18, and the locked state is released, and then the pallet can be pulled again for position adjustment. The present utility model fixes the fixed chassis in the carriage. After pulling out the pallet, place the items on the pallet 19. It is convenient to pick up and place the items on both sides of the rear door under the vehicle, avoiding the trouble and danger of climbing into the carriage to carry items, and there is no need to bend over or squat down too much to pick up and place items, greatly reducing the operation difficulty when picking up and placing items.

[0032] The above is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still belong to the protection scope of the technical solution of the present utility model.
