A baffle device for unpowered cargo pallets

Abstract

This utility model relates to a baffle device for a non-powered cargo flatbed truck. The input end of a rotary plunger is connected to a connecting assembly, and the output end of the rotary plunger is used to lock a locking wheel. A U-shaped trigger plate is connected to the connecting assembly, and a trigger rod is mounted on two trigger bases via a trigger shaft, with the bottom of the trigger rod located at the U-shaped trigger plate. Pushing or pulling the trigger rod forward or backward disengages the output end of the rotary plunger from the locking wheel, releasing the baffle. The above technical solution allows the trigger rod to be pushed forward or pulled backward to trigger the U-shaped trigger plate, causing it to move forward or backward. The force is then transmitted to the rotary plunger via the connecting assembly, causing the output end of the rotary plunger to rotate and release the locking wheel. The baffle then rises under the action of a first elastic element. Through bidirectional triggering, the baffle can still rise when the non-powered cargo flatbed truck is pulled backward to reload cargo or when it is sliding backward, providing a protective function.

Description

Technical Field

[0001] This utility model relates to the field of non-powered cargo flatbed carts, and in particular to a baffle device for non-powered cargo flatbed carts. Background Technology

[0002] like Figure 1 As shown, the non-powered cargo trolley 200a is pushed forward and moves on the transport roller 300a. The non-powered cargo trolley 200a triggers the trigger rod, causing the baffle 100a to rise. The baffle 100a blocks the non-powered cargo trolley 200a, preventing it from slipping and providing protection.

[0003] The trigger lever of the existing baffle device can only be pushed forward to trigger it. Therefore, when the baffle is retracted to its original position and the unpowered cargo cart is pulled backward to reload the cargo or slides backward, the baffle cannot be raised by pulling backward, which poses a risk during loading. Utility Model Content

[0004] Therefore, a baffle device for non-powered cargo flatbed trucks is needed to solve the technical problem that the trigger rod of the existing baffle device can only be pushed forward to trigger it. Therefore, when the baffle is retracted to its original position and the non-powered cargo flatbed truck is pulled backward to reload cargo or slides backward, the baffle cannot be raised by pulling backward, which poses a risk during loading.

[0005] To achieve the above objectives, this utility model provides a baffle device for a non-powered cargo flatbed truck, comprising:

[0006] The baffle mechanism includes a baffle mounting base, a snap-on wheel, a baffle, a mounting shaft, and a first elastic member. The baffle mounting base has a receiving cavity for accommodating the baffle. The snap-on wheel is rotatably mounted on one side of the baffle mounting base. One side of the baffle is mounted in the receiving cavity via the mounting shaft, and the mounting shaft is mounted in the snap-on wheel. One side of the first elastic member is connected to the baffle mounting base, and the other side of the first elastic member is connected to the snap-on wheel.

[0007] The connecting mechanism includes a mounting plate and a knob plunger and a connecting assembly installed in the mounting plate. The mounting plate is connected to the baffle mounting seat. The input end of the knob plunger is connected to the connecting assembly. The output end of the knob plunger is used to lock the snap-on wheel.

[0008] The triggering mechanism includes a U-shaped trigger plate, two trigger bases, a trigger rod, and a trigger shaft. The U-shaped trigger plate is connected to the connecting assembly. The two trigger bases are respectively installed on both sides of the mounting plate. The trigger rod is installed on the two trigger bases through the trigger shaft, and the bottom of the trigger rod is located at the U-shaped trigger plate.

[0009] Pushing the trigger lever forward or pulling it backward causes the output end of the knob plunger to disengage from the locking wheel, allowing the baffle to unfold from the receiving cavity.

[0010] Unlike existing technologies, the above-mentioned technical solution features a trigger rod that can be pushed forward or pulled backward to trigger the U-shaped trigger plate. The U-shaped trigger plate then moves forward or backward, and the force is transmitted to the knob plunger through the connecting assembly. This causes the output end of the knob plunger to rotate, releasing the restraint on the locking wheel, and the baffle rises under the action of the first elastic element. Through bidirectional triggering, the baffle can still rise when the unpowered cargo flatcar is pulled backward to reload cargo or when it slides backward, thus providing a protective function.

[0011] In one embodiment of this utility model, the connecting assembly includes a first connecting rod and a second connecting rod. One end of the first connecting rod is connected to the input end of the knob plunger, the other end of the first connecting rod is connected to one end of the second connecting rod, and the other end of the second connecting rod is connected to the U-shaped trigger plate.

[0012] Thus, the input end of the rotary plunger can be connected to the U-shaped trigger plate via two connecting rods, allowing the movement of the U-shaped trigger plate to be converted into the movement of the rotary plunger. Additionally, the two connecting rods can extend the distance between the U-shaped trigger plate and the rotary plunger, facilitating the triggering of unpowered cargo carts.

[0013] In one embodiment of this utility model, the connecting mechanism further includes a reset component, which is used to reset the connecting component.

[0014] Thus, by setting a reset component, the connecting components can be automatically restored to their original state, thereby enabling the trigger rod to repeatedly trigger the U-shaped trigger plate.

[0015] In one embodiment of this utility model, the reset assembly includes a sleeve, a second elastic element, a reset post, and a limiting post. The sleeve is installed on one side of the mounting plate. The second elastic element is sleeved outside the sleeve and has two elastic output lines extending along a first direction. The reset post is installed on the second connecting rod and is located between the two elastic output lines. The limiting post is installed on the other side of the mounting plate and is used to contact the elastic output lines to reset the connecting assembly.

[0016] Thus, the two elastic output lines are used for the forward and backward movement of the second connecting rod, respectively. When the second connecting rod moves forward and backward, the reset post drives the corresponding elastic output line to move along with it. The second elastic element deforms until the knob plunger completes its movement and returns to its original state. During this process, the reset post is driven to return to its original state until the limit post abuts against the elastic output line. At this time, the connection assembly reset is completed.

[0017] As one embodiment of this utility model, the connecting assembly further includes two or more guide sleeves, which are installed at intervals in the mounting plate along the second direction and sleeved on the outside of the second connecting rod. The guide sleeves guide the second connecting rod to move forward or backward along the second direction.

[0018] In this way, by setting two or more guide sleeves to guide the second connecting rod to move in a specified direction, the deviation of the movement trajectory of the second connecting rod due to excessive length can be avoided.

[0019] As one embodiment of this utility model, the triggering mechanism further includes a transition plate, a rotating shaft, and a third elastic member. The transition plate is installed at the other end of the second connecting rod. The U-shaped trigger plate is connected to the transition plate through the rotating shaft. The third elastic member is sleeved outside the rotating shaft. One side of the third elastic member is connected to the transition plate, and the other side of the third elastic member is connected to the U-shaped trigger plate.

[0020] Thus, by setting a third elastic element outside the rotating shaft, connecting the transition plate and the U-shaped trigger plate on both sides, the U-shaped trigger plate can be restored to its original shape, while also reducing vibration during triggering.

[0021] As one embodiment of this utility model, the triggering mechanism further includes two fourth elastic elements. The trigger rod is located in the middle of the trigger shaft, and the two fourth elastic elements are sleeved on the outside of the trigger shaft and are respectively located on both sides of the trigger rod. One side of the fourth elastic element is connected to the trigger base, and the other side of the fourth elastic element is connected to the trigger rod.

[0022] Thus, by setting a fourth elastic element, the trigger lever can automatically return to its original state after use, allowing the trigger lever to be triggered repeatedly.

[0023] In one embodiment of this utility model, the baffle mounting base is arranged parallel to the first direction, and the mounting plate is arranged parallel to the second direction, wherein the first direction and the second direction are perpendicular to each other.

[0024] In this way, setting the position of the baffle mounting seat perpendicular to the position of the mounting plate can save space occupied in a single direction, while also being compatible with the working mode of non-powered cargo flatbed trucks.

[0025] In one embodiment of this utility model, the baffle mechanism further includes a first support base, which is installed at the bottom of the baffle mounting base, and the connecting mechanism further includes a second support base, which is installed at the bottom of the mounting plate.

[0026] Thus, by setting the first support base and the second support base, the support for the baffle mechanism and the connecting mechanism can be strengthened.

[0027] The above description of the utility model is merely an overview of the technical solution of this application.

[0049] For ease of explanation, a first direction and a second direction are defined, and the first direction and the second direction are perpendicular to each other. For ease of explanation, as follows: Figure 2 and Figures 5 to 8 As shown by the arrows, the direction of arrow X is the first direction, and the direction of arrow Y is the second direction.

[0050] The trigger lever of the existing baffle device can only be pushed forward to trigger it. Therefore, when the baffle is retracted to its original position and the unpowered cargo cart is pulled backward to reload the cargo or slides backward, the baffle cannot be raised by pulling backward, which poses a risk during loading.

[0051] In view of this, this application provides a baffle device 100 for a non-powered cargo flatbed truck, including a baffle mechanism 1, a connecting mechanism 2, and a triggering mechanism 3. The baffle mechanism 1 includes a baffle mounting base 11, a latching wheel 12, a baffle 13, a mounting shaft 14, and a first elastic member 15. The baffle mounting base 11 has a receiving cavity 111 for receiving the baffle 13. The latching wheel 12 is rotatably mounted on one side of the baffle mounting base 11. One side of the baffle 13 is mounted in the receiving cavity 111 via the mounting shaft 14, and the mounting shaft 14 is mounted in the latching wheel 12. One side of the first elastic member 15 is connected to the baffle mounting base 11, and the other side of the first elastic member 15 is connected to the latching wheel 12. The connecting mechanism 2 includes a mounting plate 21 and a connecting mechanism 3. The knob plunger 22 is installed in the mounting plate 21 and the connecting assembly 23. The mounting plate 21 is connected to the baffle mounting seat 11. The input end of the knob plunger 22 is connected to the connecting assembly 23. The output end of the knob plunger 22 is used to lock the latching wheel 12. The triggering mechanism 3 includes a U-shaped trigger plate 31, two trigger bases 32, a trigger rod 33 and a trigger shaft 34. The U-shaped trigger plate 31 is connected to the connecting assembly 23. The two trigger bases 32 are respectively installed on both sides of the mounting plate 21. The trigger rod 33 is installed on the two trigger bases 32 through the trigger shaft 34. The bottom of the trigger rod 33 is located at the U-shaped trigger plate 31. When the trigger rod 33 is pushed forward or pulled backward, the output end of the knob plunger 22 disengages from the latching wheel 12 to release the baffle 13.

[0052] According to some embodiments of this application, please refer to Figures 1 to 8This embodiment relates to a baffle device 100 for a non-powered cargo flatbed truck, including a baffle mechanism 1, a connecting mechanism 2, and a triggering mechanism 3. The baffle mechanism 1 includes a baffle mounting base 11, a latching wheel 12, a baffle 13, a mounting shaft 14, and a first elastic member 15. The baffle mounting base 11 has a receiving cavity 111 for receiving the baffle 13. The latching wheel 12 is rotatably mounted on one side of the baffle mounting base 11. One side of the baffle 13 is mounted in the receiving cavity 111 via the mounting shaft 14, and the mounting shaft 14 is mounted in the latching wheel 12. One side of the first elastic member 15 is connected to the baffle mounting base 11, and the other side of the first elastic member 15 is connected to the latching wheel 12. The connecting mechanism 2 includes a mounting plate 21 and a triggering mechanism 3. The knob plunger 22 inside the mounting plate 21 is connected to the connecting assembly 23. The mounting plate 21 is connected to the baffle mounting seat 11. The input end of the knob plunger 22 is connected to the connecting assembly 23. The output end of the knob plunger 22 is used to lock the latching wheel 12. The triggering mechanism 3 includes a U-shaped trigger plate 31, two trigger bases 32, a trigger rod 33, and a trigger shaft 34. The U-shaped trigger plate 31 is connected to the connecting assembly 23. The two trigger bases 32 are respectively installed on both sides of the mounting plate 21. The trigger rod 33 is installed on the two trigger bases 32 through the trigger shaft 34. The bottom of the trigger rod 33 is located at the U-shaped trigger plate 31. When the trigger rod 33 is pushed forward or pulled backward, the output end of the knob plunger 22 disengages from the latching wheel 12 to release the baffle 13.

[0053] The first elastic element 15 is elastic, capable of elastically contracting under pressure and returning to its initial shape when the pressure is removed. It can be made of metallic elastic materials such as metal springs, or non-metallic elastic materials such as rubber or silicone. In actual operation, such as Figure 3 As shown, the baffle 13 can be retracted into the receiving cavity 111 by pressing down on it. During this process, the mounting shaft 14 rotates clockwise, causing the connected locking wheel 12 to rotate clockwise as well. The first elastic element 15 deforms until the locking wheel 12 rotates to the point where the output end of the knob plunger 22 just locks the locking wheel 12. The locking wheel 12 has a locking block, and the output end of the knob plunger 22 locks the locking block, preventing the locking wheel 12 from rotating counterclockwise and returning to its original state.

[0054] The knob plunger 22 can be a handle-shaped knob plunger 22, which is an existing structure. Specifically, it includes an operating handle (connected to a rotating cam, converting manual rotation into axial movement), a plunger body (with a built-in compression spring, providing the latch ejection force), a latch (i.e., the output end of the knob plunger 22, used to engage or disengage from the latching wheel 12), an input linkage (i.e., the input end of the knob plunger 22, connected to the connecting assembly 23 to transmit linear tension), and a reset mechanism (a two-way torsion spring, ensuring that the handle automatically returns to the locked position after release). Its working principle is as follows: the trigger rod 33 triggers the U-shaped trigger block, the connecting assembly 23 moves forward or backward along the second direction Y to pull the input linkage, the input linkage drives the rotating cam of the handle-shaped plunger to rotate, the rotating cam thus compresses the latch inward, causing the latch to disengage from the latching wheel 12, the latching wheel 12 returns to its original shape under the action of the first elastic element 15, thereby releasing the baffle 13.

[0055] Both ends of the U-shaped trigger plate 31 are trigger points, and the bottom of the trigger rod 33 is located in the middle of the U-shaped trigger plate 31. The contact surface between the U-shaped trigger plate 31 and the trigger rod 33 can be rounded to facilitate triggering. Its working principle is as follows: When the trigger rod 33 is pushed forward, it contacts the rear end of the U-shaped trigger plate 31. Under the action of the trigger rod 33, the U-shaped trigger plate 31 moves backward along the second direction Y, causing the connected assembly 23 connected to it to move backward as well. This ultimately causes the output end of the knob plunger 22 to disengage from the locking wheel 12, releasing the baffle 13. When the trigger rod 33 is pulled backward, it contacts the front end of the U-shaped trigger plate 31. Under the action of the trigger rod 33, the U-shaped trigger plate 31 moves forward along the second direction Y, causing the connected assembly 23 connected to it to move forward as well. This ultimately causes the output end of the knob plunger 22 to disengage from the locking wheel 12, releasing the baffle 13.

[0056] The above technical solution features a trigger rod 33 that can be pushed forward or pulled backward to trigger the U-shaped trigger plate 31. The U-shaped trigger plate 31 then moves forward or backward, and the force is transmitted to the knob plunger 22 through the connecting component 23. This causes the output end of the knob plunger 22 to rotate and release the restriction on the locking wheel 12, and the baffle 13 rises under the action of the first elastic element 15. Through bidirectional triggering, the baffle 13 can still rise when the unpowered cargo cart is pulled backward and needs to be reloaded or when it slides backward, thus providing a protective function.

[0057] like Figure 2 As shown, the connecting assembly 23 includes a first connecting rod 231 and a second connecting rod 232. One end of the first connecting rod 231 is connected to the input end of the knob plunger 22, and the other end of the first connecting rod 231 is connected to one end of the second connecting rod 232. The other end of the second connecting rod 232 is connected to the U-shaped trigger plate 31.

[0058] The first connecting rod 231 can be a ball-head pull rod, and it can be connected to the input end of the knob plunger 22 and the second connecting rod 232 by welding. The second connecting rod 232 is arranged parallel to the second direction Y.

[0059] Thus, the input end of the rotary plunger 22 can be connected to the U-shaped trigger plate 31 via two connecting rods, allowing the movement of the U-shaped trigger plate 31 to be converted into the movement of the rotary plunger 22. Furthermore, the two connecting rods can extend the distance between the U-shaped trigger plate 31 and the rotary plunger 22, facilitating the triggering of unpowered cargo carts.

[0060] like Figure 2 As shown, the connecting mechanism 2 also includes a reset component 24, which is used to reset the connecting component 23.

[0061] The reset component 24 can be an existing bidirectional reset structure, and the connection component 23 can be moved forward or backward to restore the original state.

[0062] Thus, by setting the reset component 24, the connection component 23 can be automatically restored to its original state, thereby enabling the trigger rod 33 to repeatedly trigger the U-shaped trigger plate 31.

[0063] like Figures 6 to 8 As shown, the reset assembly 24 includes a sleeve 241, a second elastic element 242, a reset post 243, and a limiting post 244. The sleeve 241 is mounted on one side of the mounting plate 21. The second elastic element 242 is sleeved outside the sleeve 241 and has two elastic output lines 2421 extending along the first direction X. The reset post 243 is mounted on the second connecting rod 232 and is located between the two elastic output lines 2421. The limiting post 244 is mounted on the other side of the mounting plate 21 and is used to contact the elastic output lines 2421 to reset the connecting assembly 23.

[0064] The second elastic element 242 can be a high-carbon steel V-shaped spring. The working principle of the reset assembly 24 is as follows: when the trigger rod 33 is pushed forward or pulled backward, the reset post 243 moves to compress any one of the elastic output wires 2421, causing the elastic output wire 2421 to deform. At the same time, the second connecting rod 232 moves to drive the knob plunger 22 to unlock. When the baffle 13 is released, the elastic output wire 2421 returns to its original state under the action of the limiting post 244.

[0065] Thus, the two elastic output lines 2421 are used for the forward and backward movement of the second connecting rod 232, respectively. When the second connecting rod 232 moves forward and backward, the reset post 243 drives the corresponding elastic output line 2421 to move along with it. The second elastic element 242 deforms until the knob plunger 22 completes its movement and returns to its original state. During this process, the reset post 243 is driven to return to its original state until the limit post 244 abuts against the elastic output line 2421. At this time, the connection assembly 23 is reset.

[0066] like Figure 2 and Figures 6 to 8 As shown, the connecting assembly 23 also includes two or more guide sleeves 233, which are installed at intervals in the mounting plate 21 along the second direction Y and sleeved outside the second connecting rod 232. The guide sleeves 233 guide the second connecting rod 232 to move forward or backward along the second direction Y.

[0067] In this way, by setting two or more guide sleeves 233 to guide the second connecting rod 232 to move in a specified direction, the deviation of the movement trajectory of the second connecting rod 232 due to excessive length can be avoided.

[0068] like Figure 5 As shown, the triggering mechanism 3 also includes a transition plate 35, a rotating shaft 36, and a third elastic element 37. The transition plate 35 is installed at the other end of the second connecting rod 232. The U-shaped trigger plate 31 is connected to the transition plate 35 through the rotating shaft 36. The third elastic element 37 is sleeved on the outside of the rotating shaft 36. One side of the third elastic element 37 is connected to the transition plate 35, and the other side of the third elastic element 37 is connected to the U-shaped trigger plate 31.

[0069] The transition plate 35 can be welded to the other end of the second connecting rod 232. The third elastic element 37 is elastic, can elastically contract when subjected to pressure, and can return to its initial shape when the pressure is removed. It can be made of metallic elastic materials such as metal springs, or non-metallic elastic materials such as rubber and silicone.

[0070] Thus, by setting a third elastic element 37 around the rotating shaft 36 and connecting the transition plate 35 and the U-shaped trigger plate 31 on both sides, the U-shaped trigger plate 31 can be restored to its original state, while also reducing vibration during triggering.

[0071] like Figure 2 , Figure 4 and Figure 5 As shown, the triggering mechanism 3 also includes two fourth elastic elements 38. The trigger rod 33 is located in the middle of the triggering shaft 34. The two fourth elastic elements 38 are sleeved on the outside of the triggering shaft 34 and are located on both sides of the trigger rod 33 respectively. One side of the fourth elastic element 38 is connected to the triggering base 32, and the other side of the fourth elastic element 38 is connected to the trigger rod 33.

[0072] The fourth elastic element 38 is elastic, can elastically contract when subjected to pressure, and can return to its initial shape when the pressure is removed. It can be made of metallic elastic materials such as metal springs, or non-metallic elastic materials such as rubber and silicone.

[0073] Thus, by setting the fourth elastic element 38, the trigger rod 33 can automatically return to its original state after use, so that the trigger rod 33 can be triggered repeatedly.

[0074] like Figure 2 As shown, the baffle mounting base 11 is arranged parallel to the first direction X, and the mounting plate 21 is arranged parallel to the second direction Y, wherein the first direction X and the second direction Y are perpendicular to each other.

[0075] In this way, by setting the position of the baffle mounting seat 11 perpendicular to the position of the mounting plate 21, space occupied in a single direction can be saved, while also being compatible with the working mode of the non-powered cargo flatbed truck.

[0076] like Figure 2 As shown, the baffle mechanism 1 also includes a first support seat 16, which is installed at the bottom of the baffle mounting seat 11. The connecting mechanism 2 also includes a second support seat, which is installed at the bottom of the mounting plate 21.

[0077] Thus, by setting the first support seat 16 and the second support seat, the support for the baffle mechanism 1 and the connecting mechanism 2 can be strengthened.

[0078] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model.
