Detailed implementation manners

[0032] Although the present utility model can be easily embodied in different forms of embodiments, only some specific embodiments are shown in the drawings and will be described in detail in this specification. At the same time, it can be understood that this specification should be regarded as a demonstration of the principle of the present utility model and is not intended to limit the present utility model to what is described herein.

[0033] Thus, a feature pointed out in this specification will be used to illustrate one of the features of one embodiment of the present utility model, rather than implying that each embodiment of the present utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to show possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combination is not intended to be limiting.

[0034] In the embodiments shown in the drawings, the indication of directions (such as up, down, left, right, front, and back) is used to explain that the structures and movements of various elements of the present utility model are not absolute but relative. When these elements are in the positions shown in the drawings, these explanations are appropriate. If the position descriptions of these elements change, then the indication of these directions also changes accordingly.

[0035] The present utility model provides a trolley tray, which is used to load the flat trolley 3. This trolley tray realizes the loading and limiting of the trolley 3, enabling the trolley 3 to be stably loaded, facilitating the user to directly ship the trolley tray loaded with the trolley 3 to the downstream for use, and improving the scope of application.

[0036] This application defines that the first direction and the second direction are perpendicular to each other and both are in the horizontal direction. For the convenience of description, the following first direction is the front-back direction shown in the figure, and the following second direction is the left-right direction shown in the figure.

[0037] Figure 1 The structural schematic diagram of the trolley tray is shown from the first perspective. Figure 2 The structural schematic diagram of the trolley 3 on the trolley tray is shown. Combining Figure 1 and Figure 2 , the trolley tray includes a tray body 1 and at least one limiting mechanism 2. At least two guiding grooves 1111 with openings facing upward are provided on the tray body 1; the guiding grooves 1111 extend along the front-back direction and are through, and at least two guiding grooves 1111 are arranged at intervals along the left-right direction. The limiting mechanism 2 is located between two adjacent guiding grooves 1111. The trolley 3 generally has a load-carrying plate and pulleys provided at the bottom of the load-carrying plate. The pulleys of the trolley 3 slide into the guiding grooves 1111, and the limiting mechanism 2 avoids the moving track of the pulleys of the trolley 3 and can intercept or unlock the load-carrying plate of the trolley 3. Moreover, the limiting mechanism 2 includes limiting members 21 arranged at the front end and the rear end of the tray body 1 respectively.

[0038] Furthermore, the limiting member 21 includes a first connecting rod 211 and a second connecting rod 212 arranged in sequence along the left-right direction. The first axial end of the first connecting rod 211 is rotatably connected to the tray body 1, the first axial end of the second connecting rod 212 is rotatably connected to the tray body 1, and the second axial end of the first connecting rod 211 and the second axial end of the second connecting rod 212 are rotatably connected. Among them, the first connecting rod 211 and the second connecting rod 212 can move away from each other along the second direction and can rotate upward to form an angle and protrude from the top surface of the tray body 1, or move closer to each other along the second direction and rotate downward to be flush with or lower than the top surface of the tray body 1.

[0039] Specifically, by adjusting the relative rotational positions of the first connecting rod 211 and the second connecting rod 212 on the limiting member 21, the rotational connection position between the first connecting rod 211 and the second connecting rod 212 moves upward, so that an angle is formed between the first connecting rod 211 and the second connecting rod 212 and protrudes from the top surface of the tray body 1, realizing the function of intercepting and locking the vehicle to prevent the trolley 3 from slipping off the tray body 1, or causing the rotational connection position between the first connecting rod 211 and the second connecting rod 212 to move downward, so that the first connecting rod 211 and the second connecting rod 212 are gradually flattened and flush with or lower than the top surface of the tray body 1, realizing the unlocking function, so that the trolley 3 can slide into or out of the trolley tray through the guiding grooves 1111.

[0040] The guide groove 1111 is through-through from front to back. The two ends of the tray body 1 in the front-to-back direction are provided with limit members 21, so that the flatbed trolley 3 can slide in or out at the front side or the rear side of the tray body 1. In actual use, the staff can directly kick the first connecting rod 211 and the second connecting rod 212 with their feet to stop and lock the vehicle. Or the first connecting rod 211 and the second connecting rod 212 can be stepped flat to unlock the vehicle. It is convenient for the staff to operate and to switch the stop, lock and unlock functions of the limit mechanism 2.

[0041] In the present application, the first link 211 and the second link 212 being flush with the top surface of the pallet body 1 means that the first link 211 and the second link 212 have a plane or structural part that is at the same level as the top surface of the pallet body 1. As long as the first link 211 and the second link 212 are lower than the bottom surface of the loading plate of the trolley 3, the trolley 3 can smoothly enter and exit the pallet body 1.

[0042] The present embodiment has three guide slots 1111 and two limit mechanisms 2, and the guide slots 1111 can correspond to at least one row of pulleys along the front-back direction sliding in. In addition, the guide slots 1111 can also have two and the limit mechanism 2 can have one.

[0043] The material of the pallet body 1 can be stainless steel to improve the strength. The pallet body 1 includes a support frame 11, and the support frame 11 includes two protrusions 112 and support portions 111 arranged on the left and right sides of the protrusion 112. The support frame 11 extends forward and backward. The support portion 111 is configured with a guide groove 1111 with an upward opening, and the protrusion 112 extends upward beyond the guide groove 1111. The protrusion 112 is configured with a slot 1121 with a downward opening and through the front and back, and the slot 1121 is used for the fork of a forklift to be inserted, and the limiter 21 is arranged at the top of the front and rear ends of the protrusion 112.

[0044] Specifically, the support portion 111 and the protrusion 112 are arranged alternately, the top surface of the protrusion 112 is opposite to the bottom surface gap of the loading plate of the trolley 3, and the limiter 21 is staggered from the pulley track of the trolley 3. When the first connecting rod 211 and the second connecting rod 212 protrude upward to enter the interception and locking state, the height of the protrusion 112 corresponds to the front and rear of the loading plate of the trolley 3, thereby limiting the forward and backward movement of the trolley 3. When the first connecting rod 211 and the second connecting rod 212 are flattened downward to enter the unlocking state, the overall height of the limiter 21 is lower than the bottom surface of the loading plate of the trolley 3, ensuring that the trolley 3 can smoothly enter or exit the pallet body 1. The forks of the external forklift can be inserted into the two slots 1121, thereby realizing the transfer of the trolley pallet and facilitating transportation.

[0045] The support portion 111 includes a bottom plate and first side plates connected to the left and right sides of the bottom plate. A guide groove 1111 that penetrates front to back and opens upward is constructed between the bottom plate and the two first side plates.

[0046] The protruding portion 112 includes second side plates that are spaced apart from each other left and right, a top plate connecting the tops of the two second side plates, and the bottom of the side plate is connected to the supporting portion 111. Among them, the second side plate is joined to the top of the first side plate. In fact, the first side plate and the second side plate can be integrally formed.

[0047] In order to improve the structural strength of the tray body 1, in the present application, a plurality of support bars 12 are provided on at least one of the two second side plates of the protruding portion 112. The support bars 12 extend vertically, and the plurality of support bars 12 are spaced apart in the front-rear direction. Specifically, the support bars 12 can maintain the verticality of the second side plate and reduce the deformation of the tray body 1. In the scenario where a plurality of trolley trays are stacked up and down, it is possible to prevent the slot 1121 of the tray body 1 from expanding and deforming outward, and improve the service life of the trolley tray.

[0048] In addition, support bars 12 can also be provided on both second side plates. In this embodiment, the support bars 12 are provided on the inner side walls of the slots 1121 to reduce interference. At least one support bar 12 is provided on the front side and the rear side of the protruding portion 112 to support below the limiting mechanism 2.

[0049] Reinforcing blocks 13 are provided at positions corresponding to the support bars 12 on the top surface of the protruding portion 112. In the scenario where a plurality of trolley trays are stacked, the reinforcing blocks 13 can be regarded as thickening the position of the protruding portion 112, improving the strength of the protruding portion 112, and reducing the deformation of the protruding portion 112 caused by the bottom of the reinforcing block 13 of the upper trolley tray.

[0050] In this embodiment, the reinforcing blocks 13 are correspondingly arranged with the support bars 12 corresponding to the front end and the rear end of the protruding portion 112. Both the support bars 12 and the reinforcing blocks 13 are made of stainless steel.

[0051] In order to improve the stability of the trolley 3 entering and exiting the trolley tray, the tray body 1 further includes a track assembly. The track assembly is correspondingly arranged with the supporting portion 111, and the track assembly is arranged on the inner bottom surface of the guiding groove 1111, that is, on the top surface of the bottom plate. The track assembly includes two track plates 14 spaced apart in the left-right direction. The bottom of the track plate 14 is arranged on the top surface of the bottom plate and extends upward. A guide rail 141 extending in the front-rear direction is formed between the two track plates 14 and the inner bottom surface of the guiding groove 1111. The guide rail 141 guides the pulleys of the trolley 3, reduces the collision between the trolley 3 and the tray body 1, and improves the service life of the trolley tray. One guide rail 141 or two or more guide rails 141 can be formed on the guiding groove 1111 through the track plates 14.

[0052] Further, the front and rear ends of the guide rail 141 are open with an outer diameter that gradually expands. The port of the guide rail 141 expands outward to facilitate the entry of the pulleys of the trolley 3.

[0053] To further improve the strength of the track assembly, a plurality of first reinforcing ribs 15 are connected between the side wall of the track plate 14 facing away from the guide rail 141 and the second side plate of the convex portion 112, improving the structural strength of the track assembly and the convex portion 112.

[0054] Moreover, a plurality of second reinforcing ribs 16 are connected between the side wall of the track plate 14 facing away from the guide rail 141 and the first side plate of the support portion 111, improving the structural strength of the track assembly and the support portion 111.

[0055] As Figure 1 shown, the limiting mechanism 2 is provided with a limiting member 21 corresponding to one end of the trolley 3 entering the tray body 1, and two limiting members 21 are provided corresponding to the end of the trolley 3 exiting the tray body 1, which can play a role in distinguishing the entry and exit directions of the trolley 3.

[0056] Figure 3 The rear view showing the partial structure of the trolley tray, in which the limiting member 21 is in the stop and locking state, Figure 4 shows Figure 3 the cross-sectional view of the partial structure in Figure 5 along the position of the limiting mechanism 2, and the rear view showing the partial structure of the trolley tray, in which the limiting member 21 is in the unlocked state, Figure 6 shows the partial structure diagram of the trolley tray from another perspective.

[0057] As Figure 3 shown, the second connecting rod 212 is provided with an adjustment hole 2121, the length of the adjustment hole 2121 extends along the axial direction of the second connecting rod 212, a rotating shaft 2111 is provided at the second axial end of the first connecting rod 211, the rotating shaft 2111 penetrates into the adjustment hole 2121, and the rotating shaft 2111 can move along the length direction of the adjustment hole 2121.

[0058] Specifically, both the adjustment hole 2121 and the rotating shaft 2111 extend axially in the front-rear direction, the length of the adjustment hole 2121 extends along the axial direction of the second connecting rod 212. When the first connecting rod 211 and the second connecting rod 212 rotate upward, the first connecting rod 211 and the second connecting rod 212 move away from each other, causing the rotating shaft 2111 to slide along the adjustment hole 2121, and the rotating shaft 2111 slides in the direction away from the first end of the second connecting rod 212. Combining Figure 3 and Figure 6 , when the limiting member 21 is in the stop and locking state, the rotating shaft 2111 slides to the position close to the first axial end of the second connecting rod 212 of the adjustment hole 2121. When the first connecting rod 211 and the second connecting rod 212 rotate upward to form an angle, the first connecting rod 211 and the second connecting rod 212 can be locked by the locking member to maintain stable limiting.

[0059] In fact, in some other embodiments, it is also possible that the first end of the first link 211 can slide left and right along the tray body 1, or the first end of the second link 212 can slide left and right along the tray body 1, so that when the rotating connection part between the first link 211 and the second link 212 is lifted or lowered, a moving position for the first link 211 or the second link 212 is reserved to ensure that the rotating connection part can be lifted or lowered.

[0060] Referring to Figure 4 , further, the limiting member 21 further includes an elastic member 213. One end of the elastic member 213 is connected to the rotating shaft 2111, and the other end of the elastic member 213 is connected to the first axial end of the second link 212. When the second link 212 is upward beyond the tray body 1, the rotating shaft 2111 moves along the adjusting hole 2121 and away from the first axial end of the second link 212, and the elastic member 213 elongates and has a tendency to return to its natural state. In fact, the elastic member 213 can be in a natural state at this time. The addition of the elastic member 213 makes the first link 211 and the second link 212 have a reset tendency to rotate upward, making the limiting member 21 more stable when in the function of intercepting and locking the vehicle, which is convenient for the transportation of the trolley 3. In this embodiment, the elastic member 213 is a spring.

[0061] Referring to Figure 5 , when the second link 212 is downward flush with or lower than the top surface of the tray body 1, the limiting member 21 is in an unlocked state, and the rotating shaft 2111 moves along the adjusting hole 2121 and close to the first axial end of the second link 212, and the rotating shaft 2111 moves to a position close to the first axial end of the second link 212 in the adjusting hole 2121, so that the elastic member 213 is continuously compressed and in a compressed state.

[0062] In fact, in order to maintain the unlocked state of the limiting member 21, the rotating connection point between the first link 211 and the second link 212 can continue to move downward, so that an included angle structure with an upward opening is formed between the first link 211 and the second link 212. At the same time, the elastic member 213 can press against the rotating shaft 2111 and the first connecting shaft 2122 to position the first link 211 and the second link 212.

[0063] Further, in order to improve the connection stability of the elastic member 213, a first connecting shaft 2122 is provided at the first axial end of the second connecting rod 212, and the second connecting rod 212 is rotatably connected to the tray body 1 through the first connecting shaft 2122. A first extension block 214 extending toward the first connecting shaft 2122 is provided on the rotating shaft 2111, and a second extension block 215 extending toward the rotating shaft 2111 is provided on the first connecting shaft 2122. Two ends of the elastic member 213 are respectively sleeved on the first extension block 214 and the second extension block 215. The first extension block 214 and the second extension block 215 provide connection positions for the elastic member 213 and reduce the detachment of the elastic member 213.

[0064] The first extension block 214 and the second extension block 215 may extend parallel to the length extension direction of the second connecting rod 212. In other embodiments, the first extension block 214 and the second extension block 215 may be connected to each other to form an integral structure. Additionally, the first extension block 214 and the second extension block 215 may be staggeredly extended at an angle to each other.

[0065] In addition, a second connecting shaft 2112 may be provided at the first end of the first connecting rod 211, and the first connecting rod 211 is rotatably connected to the tray body 1 through the second connecting shaft 2112, wherein the first connecting shaft 2122, the second connecting shaft 2112, and the rotating shaft 2111 all extend in the front-rear direction.

[0066] The rotating shaft 2111 may be welded to the first connecting rod 211 as a whole, or the rotating shaft 2111 may be rotatably connected to the first connecting rod 211, and the rotating shaft 2111 is positioned on the first connecting rod 211 by means of a circlip, a limiting block, etc. The first connecting shaft 2122 may be welded to the tray body 1, or the first connecting shaft 2122 may be able to rotate relative to the second connecting rod 212 and the tray body 1, and the first connecting shaft 2122 positions the second connecting rod 212 and the tray body 1 by means of a circlip, a limiting block, etc. The second connecting shaft 2112 may be welded to the tray body 1, or the second connecting shaft 2112 may be able to rotate relative to the first connecting rod 211 and the tray body 1, and the second connecting shaft 2112 positions the first connecting rod 211 and the tray body 1 by means of a circlip, a limiting block, etc.

[0067] Refer to Figure 6, the second link 212 is provided with a receiving groove 2123 extending axially, and adjusting holes 2121 are provided on opposite side walls of the receiving groove 2123. Both ends of the rotating shaft 2111 are respectively inserted into the two adjusting holes 2121, and the elastic member 213 is located in the receiving groove 2123. Among them, the second link 212 is sleeved on the second end of the first link 211 through the opening of the receiving groove 2123, and both ends of the rotating shaft 2111 are connected to the two adjusting holes 2121, so that the rotating shaft 2111 is uniformly stressed, and at the same time, the sliding stability of the rotating shaft 2111 along the adjusting hole 2121 is improved.

[0068] In this embodiment, the first connecting shaft 2122 connected to the second link 212 is also located in the receiving groove 2123 and penetrates through opposite sides of the receiving groove 2123. Axial ends of the elastic member 213 are respectively connected to the rotating shaft 2111 and the first connecting shaft 2122, and the elastic member 213 is located in the receiving groove 2123, improving the structural stability. In this embodiment, the opening of the receiving groove 2123 on the second link 212 faces downward.

[0069] In fact, the first link 211 is also provided with a receiving groove 2123 extending axially, and the second connecting shaft 2112 penetrates through opposite side surfaces of the receiving groove 2123, improving the connection stability of the second connecting shaft 2112.

[0070] In a specific embodiment of the present utility model, when the trolley 3 needs to enter and exit the trolley tray, the rotational connection position between the first link 211 and the second link 212 is pressed downward, so that the first link 211 and the second link 212 rotate downward and have a moving trend of approaching each other, so that the rotating shaft 2111 on the first link 211 can slide along the adjustment hole 2121 on the second link 212 to a position close to the first end of the second link 212, and the rotating shaft 2111 and the first connecting shaft 2122 on the second link 212 approach each other, so that the spring is compressed and in a compressed state. At this time, the first link 211 and the second link 212 rotate and are positioned below the load plate of the trolley 3, so that the trolley 3 can freely enter and exit within the guide groove 1111 formed by the support portion 111 along the guide rail 141 of the tray body 1. When the trolley tray needs to stop the trolley 3 from entering and exiting, the limiting mechanism 2 is correspondingly provided with limiting members 21 at both the front and rear ends of the convex portion 112. The rotational connection position between the first link 211 and the second link 212 is lifted upward, so that the first link 211 and the second link 212 rotate upward and have a moving trend of moving away from each other, so that the rotating shaft 2111 on the first link 211 can slide along the adjustment hole 2121 to one end of the adjustment hole 2121 close to the second end of the second link 212, and the rotating shaft 2111 and the first connecting shaft 2122 on the second link 212 move away from each other, so that the spring gradually returns to its original state. At this time, an angle with the opening facing downward is formed between the first link 211 and the second link 212, and the height of this angle portion is exactly opposite to the load plate of the trolley 3, thereby being able to limit the trolley 3 from sliding out within the tray body 1. When it is necessary to carry the trolley tray after loading the trolley 3, by inserting the fork of the forklift into the two slots 1121 with the opening facing downward formed by the convex portion 112, the forklift can lift the trolley tray as a whole and transport it.
