Description

Technical Field

[0001] This application belongs to the field of forklift technology, and specifically relates to a forklift. Background Technology

[0002] A pallet loader is a type of forklift capable of handling pallets in a grid pattern. Typically, a pallet loader consists of a frame and forks connected to the frame, allowing for the movement of goods via the forks. The frame is equipped with an electric actuator and a ramp slider. The forks are fitted with load-bearing wheels, which are connected by a linkage mechanism. The electric actuator moves the ramp slider, which in turn moves the linkage mechanism, causing the load-bearing wheels to be housed within the forks. At this point, the forks are not allowed to lift, as doing so would damage the electric actuator and other components. In related technologies, a magnetic switch is installed on the frame, and the forks are protected by software. When the magnetic switch receives a retraction signal, the load-bearing wheels are housed within the forks, and fork lifting is restricted by software control. However, in these technologies, if a software malfunction occurs, the forks may lift even with the load-bearing wheels housed within them, potentially damaging components such as the electric actuator. Utility Model Content

[0003] The purpose of this application is to provide a forklift that at least solves the problem that, in the event of a software malfunction, the forks may lift when the load-bearing wheels are housed inside the forks, causing damage to components such as the electric push rod.

[0004] This application provides a pallet truck, which includes: a frame, forks, an electric push rod, a ramp slider, and a blocking assembly;

[0005] The forks are connected to the frame and are used to lift or lower relative to the frame in a first direction. A limiter is provided on the side of the forks facing the frame.

[0006] The electric push rod is mounted on the frame, the inclined slider is connected to the electric push rod, and both the electric push rod and the inclined slider are located on the side of the fork facing the frame. The blocking assembly is connected to the inclined slider. The electric push rod is used to drive the inclined slider to move along the second direction, so that the inclined slider drives the blocking assembly to switch between a first position and a second position. The first direction intersects the second direction.

[0007] Wherein, when the blocking component is in the first position, at least a portion of the blocking component is located above the limiting member, and the blocking component prevents the limiting member from being lifted along the first direction; when the blocking component is in the second position, the blocking component releases its obstruction of the limiting member.

[0008] Optionally, the blocking assembly includes a sliding rod, a sliding bracket, and a blocking structure;

[0009] Both ends of the sliding rod are fixed to the inclined slider. The first end of the sliding bracket is slidably connected to the sliding rod, and the second end of the sliding bracket is connected to the blocking structure. The inclined slider is used to drive the sliding rod to move along the second direction, so that the sliding rod drives the sliding bracket to move along the second direction, so that the sliding bracket drives the blocking structure to move along the second direction. The blocking structure switches between the first position and the second position.

[0010] When the blocking structure is in the first position, at least a portion of the blocking structure is located above the limiting member, and the blocking structure prevents the limiting member from being lifted in the first direction; when the blocking structure is in the second position, the blocking structure releases its obstruction of the limiting member.

[0011] Optionally, the blocking structure includes a fixing block and a blocking element;

[0012] The fixing block is fixed to the vehicle frame, the blocking member is slidably connected to the fixing block, the second end of the sliding bracket is connected to the blocking member, and the sliding bracket is used to drive the blocking member to move along the second direction so that the blocking member can switch between the first position and the second position.

[0013] When the blocking member is in the first position, at least a portion of the blocking member is located above the limiting member, and the blocking member prevents the limiting member from rising in the first direction; when the blocking member is in the second position, the blocking member releases its obstruction of the limiting member.

[0014] Optionally, the frame is connected to a load-bearing member;

[0015] The inclined slider and the sliding rod are both located on the first side of the support member, and the fixing block and the blocking member are located on the second side of the support member. The first side and the second side are two opposite sides of the support member in the first direction.

[0016] The fixing block is fixed to the carrier, the carrier is provided with a sliding hole, the sliding hole penetrates the carrier along the first direction, the sliding hole extends along the second direction, and the sliding bracket passes through the sliding hole.

[0017] Optionally, the inclined slider is slidably connected to the carrier in the second direction, so that the inclined slider is slidable relative to the carrier in the second direction.

[0018] Optionally, the support member is provided with a slide rail on the side facing the inclined slider, the slide rail extends along the second direction, the inclined slider is connected to a sliding block, the sliding block is slidably connected to the slide rail, so that the inclined slider is slidably connected to the support member.

[0019] Optionally, the forklift further includes an elastic element, the extension and retraction direction of which is the same as the second direction, one end of which is connected to the frame, and the other end of which abuts against the sliding bracket.

[0020] Optionally, the blocking structure is connected to a first connecting structure, the frame is provided with a second connecting structure, the sliding bracket is provided with a through hole, the first connecting structure passes through the through hole, one end of the elastic member is sleeved on the first connecting structure, and the other end of the elastic member is sleeved on the second connecting structure.

[0021] Optionally, the first end of the sliding bracket is provided with a through hole, and the sliding rod passes through the through hole so that the first end of the sliding bracket is slidably connected to the sliding rod.

[0022] Optionally, the second end of the sliding bracket is provided with a through groove, and the blocking member includes a blocking body, a connecting rod and a blocking block. One end of the connecting rod is connected to the blocking body, and the other end of the connecting rod is connected to the blocking block. The blocking body is slidably connected to the fixed block.

[0023] The connecting rod passes through the through groove, and the width of the blocking block is greater than the width of the through groove, so that the second end of the sliding bracket is slidably connected to the blocking member.

[0024] In this embodiment, since the forks are connected to the frame, they can be lifted or lowered in a first direction to transport goods. Additionally, an electric push rod is mounted on the frame, and a ramp slider is connected to the electric push rod. Both the electric push rod and the ramp slider are located on the side of the forks facing the frame. Therefore, the electric push rod can push the ramp slider in a second direction, causing the ramp slider to move and accommodate the forklift's load-bearing wheels within the forks. Furthermore, a limit member is provided on the side of the forks facing the frame, and a blocking component is connected to the ramp slider. Therefore, when the electric push rod pushes the ramp slider in the second direction, the ramp slider moves the blocking component, allowing the blocking component to switch between a first position and a second position. Specifically, when the blocking component moves to the first position, at least part of the blocking component is located above the limiting member, which is equivalent to part of the blocking component being located on one side of the limiting member in the first direction. Thus, the blocking component will prevent the limiting member from lifting in the first direction, thereby blocking the forks through the limiting member and preventing the forks from lifting. When the blocking component moves to the second position, the blocking component releases its obstruction of the limiting member, thereby releasing the blocking component from obstructing the blocking member and allowing the forks to be lifted in the first direction.

[0025] In other words, in this embodiment, by setting a blocking component and connecting it to the inclined slider, the blocking component can be moved by the inclined slider, allowing it to switch between different positions. This allows the blocking component to move above the limiting member connected to the fork, thus blocking the limiting member and preventing the fork from lifting in the first direction. Specifically, when the electric push rod pushes the inclined slider to move, causing the load-bearing wheel connected to the fork to be housed inside the fork, the blocking component moves with the inclined slider above the limiting member, preventing the limiting member from lifting in the first direction. This effectively avoids the problem in related technologies where software malfunctions can cause the fork to lift when the load-bearing wheel is housed inside the fork, potentially damaging components such as the electric push rod. This effectively protects components such as the electric push rod. Attached Figure Description

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0039] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] like Figures 1 to 10 As shown in the figure, this application provides a pallet truck, which includes: a frame 10, forks 20, an electric push rod 30, a ramp slider 40, and a blocking assembly 50.

[0042] Forks 20 are connected to the frame 10 and are used to lift or lower relative to the frame 10 along a first direction X. A limiting member 201 is provided on the side of the forks 20 facing the frame 10. An electric push rod 30 is mounted on the frame 10. An inclined slider 40 is connected to the electric push rod 30, and both the electric push rod 30 and the inclined slider 40 are located on the side of the forks 20 facing the frame 10. A blocking assembly 50 is connected to the inclined slider 40. The electric push rod 30 is used to drive the inclined slider 40 to move along a second direction Y, so that the inclined slider 40 drives the blocking assembly 50 to switch between a first position and a second position. The first direction X and the second direction Y intersect. When the blocking assembly 50 is in the first position, at least part of the blocking assembly 50 is located above the limiting member 201, and the blocking assembly 50 prevents the limiting member 201 from being lifted along the first direction X. When the blocking assembly 50 is in the second position, the blocking assembly 50 releases its obstruction of the limiting member 201.

[0043] In this embodiment, since the forks 20 are connected to the frame 10, they can be lifted or lowered in the first direction X, allowing them to transport goods. Additionally, an electric push rod 30 is mounted on the frame 10, and a ramp slider 40 is connected to the electric push rod 30. Both the electric push rod 30 and the ramp slider 40 are located on the side of the forks 20 facing the frame 10. Therefore, the electric push rod 30 can push the ramp slider 40 along the second direction Y, causing the ramp slider 40 to carry the forklift's load-bearing wheels 202 within the forks 20. Furthermore, a limit member 201 is provided on the side of the forks 20 facing the frame 10, and a blocking component 50 is connected to the ramp slider 40. Therefore, when the electric push rod 30 pushes the ramp slider 40 along the second direction Y, the ramp slider 40 will move the blocking component 50, allowing the blocking component 50 to switch between a first position and a second position. Specifically, when the blocking component 50 moves to the first position, at least part of the blocking component 50 is located above the limiting member 201, which is equivalent to part of the blocking component 50 being located on one side of the limiting member 201 in the first direction X. Thus, the blocking component 50 will prevent the limiting member 201 from lifting in the first direction X, thereby preventing the forks 20 from being lifted by the limiting member 201. When the blocking component 50 moves to the second position, the blocking component 50 releases its obstruction of the limiting member 201, thereby releasing its obstruction of the blocking member 532, allowing the forks 20 to be lifted in the first direction X.

[0044] That is, in this embodiment, by setting a blocking component 50 and connecting the blocking component 50 to the inclined slider 40, the blocking component 50 can be moved by the inclined slider 40, allowing the blocking component 50 to switch between different positions. This allows the blocking component 50 to move above the limiting member 201 connected to the fork 20, thus blocking the limiting member 201 and preventing the fork 20 from lifting in the first direction X, i.e., when the electric push rod 30 pushes the inclined slider 40 to move. When the load-bearing wheel 202 connected to the fork 20 is housed inside the fork 20, the blocking component 50 moves above the limiting member 201 along the inclined slider 40, blocking the limiting member 201 from rising in the first direction X, thereby preventing the fork 20 from rising in the first direction X. This effectively avoids the problem in related technologies where software malfunctions could cause the fork 20 to rise when the load-bearing wheel 202 is housed inside the fork 20, resulting in damage to components such as the electric push rod 30. This effectively protects components such as the electric push rod 30.

[0045] It should be noted that in this embodiment, the limiting member 201 can be a block structure, or it can be a plate structure. The specific structure of the limiting member 201 is not limited in this embodiment. Furthermore, the limiting member 201 can be bolted to the fork 20. Of course, the limiting member 201 can also be installed on the fork 20 in other ways, such as welding it to the fork 20. This is not limited in this embodiment.

[0046] Additionally, in the embodiments of this application, such as Figure 1 As shown, the electric push rod 30 can be connected to the frame 10 via the push rod bracket 301. Figure 1 As shown, the electric push rod 30 is also equipped with a magnetic switch 001, which can receive signals to stop the forks 20 from lifting.

[0047] Additionally, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the blocking assembly 50 includes a sliding rod 51, a sliding bracket 52, and a blocking structure 53. Both ends of the sliding rod 51 are fixed to the inclined slider 40. The first end of the sliding bracket 52 is slidably connected to the sliding rod 51, and the second end of the sliding bracket 52 is connected to the blocking structure 53. The inclined slider 40 is used to drive the sliding rod 51 to move along the second direction Y, so that the sliding rod 51 drives the sliding bracket 52 to move along the second direction Y, so that the sliding bracket 52 drives the blocking structure 53 to move along the second direction Y. The blocking structure 53 switches between a first position and a second position. When the blocking structure 53 is in the first position, at least part of the blocking structure 53 is located above the limiting member 201, and the blocking structure 53 prevents the limiting member 201 from being lifted along the first direction X. When the blocking structure 53 is in the second position, the blocking structure 53 releases its obstruction of the limiting member 201.

[0048] Since both ends of the sliding rod 51 are fixed to the inclined plane slider 40, the first end of the sliding bracket 52 is slidably connected to the sliding rod 51, and the second end of the sliding bracket 52 is connected to the blocking structure 53, when the electric push rod 30 drives the inclined plane slider 40 to move along the second direction Y, so that the inclined plane slider 40 accommodates the load-bearing wheel 202 on the fork 20 in the fork 20, the inclined plane slider 40 will drive the sliding rod 51 to move along the second direction Y. Once the sliding rod 51 moves along the second direction Y, the sliding rod 51 will drive the sliding bracket 52 to move along the second direction Y, so that the sliding bracket 52 will drive the blocking structure 53 to move along the second direction Y, so that the blocking structure 53 can move to the first position, thereby at least part of the blocking structure 53 will move. Above the limiting member 201, the blocking structure 53 will prevent the limiting member 201 from rising in the first direction X, thus preventing the forks 20 from rising in the first direction X. When the electric push rod 30 drives the inclined slider 40 to move in the second direction Y, causing the bearing wheel 202 to extend from the forks 20, the inclined slider 40 is equivalent to being driven by the electric push rod 30 to retract to its initial position. This causes the inclined slider 40 to drive the sliding rod 51 to move in the second direction Y, returning the sliding rod 51 to its initial position. The sliding rod 51 then drives the blocking structure 53 to move in the second direction Y via the sliding bracket 52, moving the blocking structure 53 to its second position. The blocking structure 53 then releases its obstruction of the limiting member 201, allowing the forks 20 to rise in the first direction X. In other words, by setting the sliding rod 51, the sliding bracket 52, and the blocking structure 53, the inclined slider 40 can easily drive the blocking structure 53 to block the blocking member 532 on the forks 20, thereby preventing the forks 20 from rising.

[0049] It should be noted that the blocking structure 53 can be made of metal, which makes the blocking structure 53 strong and facilitates the blocking structure 53 in limiting the limiting member 201. In addition, when the blocking structure 53 moves above the limiting member 201, there is a gap between the blocking structure 53 and the limiting member 201, ensuring that the blocking structure 53 can return to its initial position later.

[0050] Additionally, in some embodiments, such as Figure 2 , Figure 3 , Figure 8 and Figure 9As shown, the blocking structure 53 includes a fixing block 531 and a blocking member 532; the fixing block 531 is fixed to the frame 10, the blocking member 532 is slidably connected to the fixing block 531, the second end of the sliding bracket 52 is connected to the blocking member 532, and the sliding bracket 52 is used to drive the blocking member 532 to move along the second direction Y, so that the blocking member 532 switches between a first position and a second position; when the blocking member 532 is in the first position, at least part of the blocking member 532 is above the limiting member 201, and the blocking member 532 prevents the limiting member 201 from being lifted along the first direction X; when the blocking member 532 is in the second position, the blocking member 532 releases its obstruction of the limiting member 201.

[0051] Since the fixing block 531 is fixed to the frame 10, the blocking member 532 is slidably connected to the fixing block 531, and the second end of the sliding bracket 52 is connected to the blocking member 532, when the electric push rod 30 drives the inclined slider 40 to move along the second direction Y, so that the inclined slider 40 accommodates the load-bearing wheel 202 on the fork 20 in the fork 20, the inclined slider 40 will drive the sliding rod 51 to move along the second direction Y. Once the sliding rod 51 moves along the second direction Y, the sliding rod 51 will drive the sliding bracket 52 to move along the second direction Y, so that the sliding bracket 52 drives the blocking member 532 to move along the second direction Y, so that the blocking member 532 moves relative to the fixing block 531, and the blocking member 532 can move to the first position, thereby at least partially blocking member 532. The 32 will move above the limiting member 201, and the blocking member 532 will prevent the limiting member 201 from lifting in the first direction X, thus preventing the forks 20 from lifting in the first direction X. When the electric push rod 30 drives the inclined slider 40 to move in the second direction Y, so that the bearing wheel 202 extends out of the forks 20, the inclined slider 40 is equivalent to being driven by the electric push rod 30 to retract to the initial position. Thus, the inclined slider 40 drives the sliding rod 51 to move in the second direction Y, so that the sliding rod 51 returns to the initial position. The sliding rod 51 will then drive the blocking member 532 to move in the second direction Y through the sliding bracket 52, so that the blocking member 532 moves to the second position. The blocking member 532 releases its obstruction of the limiting member 201, so that the forks 20 can be lifted in the first direction X. By setting a fixed block 531 and a blocking member 532, the inclined slider 40 can drive the blocking member 532 to block the blocking member 532 on the fork 20, thereby blocking the lifting of the fork 20.

[0052] It should be noted that in this embodiment, the blocking member 532 can be a rod-shaped structure, or it can be a strip-shaped structure. The specific type of the blocking member 532 is not limited in this embodiment. Additionally, a through hole can be provided on the fixing block 531, extending through the fixing block 531 along the second direction Y. The blocking member 532 passes through this through hole, allowing the blocking member 532 to be slidably connected to the fixing block 531.

[0053] Additionally, in some embodiments, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the frame 10 is connected to a carrier 101; the inclined slider 40 and the sliding rod 51 are both located on the first side of the carrier 101, and the fixing block 531 and the blocking member 532 are located on the second side of the carrier 101. The first side and the second side are opposite sides of the carrier 101 in the first direction X; the fixing block 531 is fixed to the carrier 101, and the carrier 101 is provided with a sliding hole 1011. The sliding hole 1011 penetrates the carrier 101 along the first direction X and extends along the second direction Y. The sliding bracket 52 passes through the sliding hole 1011.

[0054] Since the fixing block 531 is fixed to the carrier 101, and the carrier 101 is provided with a sliding hole 1011, the sliding hole 1011 penetrates the carrier 101 along the first direction X and extends along the second direction Y. The sliding bracket 52 passes through the sliding hole 1011. Therefore, when the electric push rod 30 drives the inclined slider 40 to move along the second direction Y, so that the inclined slider 40 accommodates the carrier wheel 202 on the fork 20 in the fork 20, the inclined slider 40 will drive the sliding rod 51 to move along the second direction Y. This will cause the sliding bracket 52 to move along the second direction Y, thus moving the sliding bracket 52 within the sliding hole 1011 on the support member 101. This allows the sliding bracket 52 to move the blocking member 532 along the second direction Y, ensuring that the sliding bracket 52 can move the blocking member 532 in the second direction Y. Furthermore, the presence of the support member 101 effectively supports the fixed block 531 and provides an installation position for the fixed block 531, facilitating its installation and consequently, the installation of the blocking structure 53. Additionally, the support member 101 also separates the inclined slider 40 from the blocking structure 53 in the first direction X, preventing potential interference between the inclined slider 40 and the blocking structure 53.

[0055] It should be noted that the support member 101 can be a plate-like structure, and its shape can be set according to actual needs. Furthermore, the support member 101 can be fixed to the frame 10 by bolts. Of course, the connection between the support member 101 and the frame 10 can also be in other ways, such as welding. The specific method of connecting the frame 10 to the support member 101 is not limited in this embodiment.

[0056] In addition, in some embodiments, the inclined slider 40 is slidably connected to the carrier 101 along the second direction Y, so that the inclined slider 40 is slidable relative to the carrier 101 along the second direction Y.

[0057] Since the inclined slider 40 and the support member 101 are slidably connected along the second direction Y, it can be ensured that the inclined slider 40 can move relative to the support member 101. Furthermore, the presence of the support member 101 can fix and guide the inclined slider 40, ensuring that the inclined slider 40 is relatively stable when moving along the second direction Y.

[0058] Additionally, in some embodiments, such as Figure 4 As shown, a slide rail 102 is provided on the side of the carrier 101 facing the inclined slider 40. The slide rail 102 extends along the second direction Y. The inclined slider 40 is connected to a sliding block 401. The sliding block 401 is slidably connected to the slide rail 102 so that the inclined slider 40 is slidably connected to the carrier 101.

[0059] Since a slide rail 102 is provided on the side of the support member 101 facing the inclined slider 40, and the slide rail 102 extends along the second direction Y, and the inclined slider 40 is connected to a sliding block 401, the sliding block 401 can be slidably connected to the slide rail 102, thus realizing the slidable connection between the inclined slider 40 and the support member 101. Therefore, when the inclined slider 40 is pushed by the electric push rod 30 and moves along the second direction Y, the inclined slider 40 can drive the sliding block 401 to move relative to the slide rail 102, so that the inclined slider 40 moves relative to the support member 101. That is, by providing the slide rail 102 and the sliding block 401, the slidable connection between the inclined slider 40 and the support member 101 can be easily achieved.

[0060] It should be noted that the number of sliding blocks 401 and the number of slide rails 102 can be set according to actual needs. The number of sliding blocks 401 can be equal to the number of slide rails 102. For example, if there are two sliding blocks 401 and two slide rails 102, the two sliding blocks 401 and two slide rails 102 are spaced apart, with one sliding block 401 slidably connected to one slide rail 102. The sliding bracket 52 can be located between the two sliding blocks 401 and between the two sliding brackets 52. Therefore, the presence of two sliding blocks 401 and two slide rails 102 ensures that the inclined slider 40 moves relatively stably relative to the support member 101. Alternatively, the number of sliding blocks 401 and slide rails 102 can be one. The specific number of sliding blocks 401 and slide rails 102 is not limited in this embodiment.

[0061] Of course, in this embodiment of the application, the inclined slider 40 and the support member 101 can be slidably connected in the second direction Y in other ways. For example, a sliding block 401 is provided on the side of the support member 101 facing the inclined slider 40, and a slide rail 102 is provided on the inclined slider 40. The sliding block 401 and the slide rail 102 are slidably connected to realize the sliding connection between the inclined slider 40 and the support member 101. Thus, when the inclined slider 40 moves, the inclined slider 40 drives the slide rail 102 to move relative to the sliding block 401 in the second direction Y.

[0062] Additionally, in some embodiments, such as Figure 4 and Figure 6 As shown, the pallet truck also includes an elastic element 60. The extension and retraction direction of the elastic element 60 is the same as the second direction Y. One end of the elastic element 60 is connected to the frame 10, and the other end of the elastic element 60 abuts against the sliding bracket 52.

[0063] Since the sliding bracket 52 is slidably connected to the sliding rod 51, when the electric push rod 30 drives the inclined slider 40 to move along the second direction Y, causing the inclined slider 40 to house the load-bearing wheel 202 on the fork 20, the inclined slider 40 will drive the sliding rod 51 to move along the second direction Y. Once the sliding rod 51 moves along the second direction Y, it will move relative to the sliding bracket 52 until it reaches the position where it connects to the frame 10. After that, when the sliding rod 51 continues to move along the second direction Y, it will cause the sliding bracket 52 to move along the second direction Y. That is, after the sliding rod 51 moves, it will not directly drive the sliding bracket 52 to move. Therefore, the sliding support 52 will not directly move the blocking member 532. This means that when the sliding rod 51 moves, the sliding support 52 will have a period of free travel, preventing the blocking member 532 from moving directly. To address this, one end of the elastic member 60 is connected to the frame 10, and the other end abuts against the sliding support 52. When the sliding rod 51 moves, the elastic member 60 applies force to the sliding support 52, causing the sliding support 52 to move the blocking member 532. This causes the blocking member 532 to move above the limiting member 201. In other words, within the free travel of the sliding support 52, the elastic member 60 will move the blocking member 532 above the limiting member 201 via the sliding support 52, thus blocking the limiting member 201. In short, by setting the elastic member 60, the blocking member 532 can be pushed above the limiting member 201 during the free travel of the sliding rod 51, ensuring that the limiting member 201 is blocked and thus preventing the forks 20 from lifting.

[0064] It should be noted that the elastic element 60 can be a spring, or it can be other elastic structures, such as a sheet. The specific type of elastic element 60 is not limited in this embodiment.

[0065] Furthermore, during forklift operation, the electric push rod 30 has a 90mm stroke, while the blocking component 532 only requires a 30mm stroke. If the blocking component 532 had a 90mm stroke, it would result in significant space and structural cost waste. Therefore, by setting the sliding rod 51, the sliding bracket 52 has a 60mm idle stroke, achieving space and structural cost savings. Specifically, the 60mm idle stroke of the sliding bracket 52... Figure 3 The dimensions are marked in the diagram.

[0066] It should be noted that in this embodiment, when the blocking member 532 is in the second position, the first end of the sliding rod 51 abuts against the sliding bracket 52 at the position where it connects with the inclined slider 40. When the blocking member 532 is in the first position, the second end of the sliding rod 51 abuts against the sliding bracket 52 at the position where it connects with the inclined slider 40. Thus, when the blocking member 532 needs to block the limiting member 201, the sliding rod 51 is moved first by the inclined slider, so that the sliding rod 51 moves relative to the sliding bracket 52, causing the first end of the sliding rod 51 to gradually move away from the sliding bracket 52, and the second end of the sliding rod 51 to gradually move closer to the sliding bracket 52. During this process, the sliding bracket 52 does not move with the movement of the sliding rod 51, which is equivalent to the empty stroke of the sliding bracket 52, until the second end of the sliding rod 51 abuts against the inclined slider 40. At this time, the sliding bracket 52 will move with the movement of the sliding rod 51. The first end of the sliding rod 51 is the end of the sliding rod 51 that is close to the fork 20, and the second end of the sliding rod 51 is the end of the sliding rod 51 that is away from the fork 20.

[0067] Additionally, in some embodiments, such as Figure 8 and Figure 10 As shown, the blocking structure 53 is connected to the first connecting structure 5311, the frame 10 is provided with the second connecting structure 1012, the sliding bracket 52 is provided with the through hole 523, the first connecting structure 53 passes through the through hole 523, one end of the elastic member 60 is sleeved on the first connecting structure 5311, and the other end of the elastic member 60 is sleeved on the second connecting structure 1012. With this arrangement, both ends of the elastic member 60 can be limited, thereby ensuring that the elastic member 60 is relatively stable during extension and retraction, and avoiding potential positional displacement during extension and retraction.

[0068] It should be noted that when the frame 10 is connected to the load-bearing member 101, the second connecting structure 1012 is connected to the load-bearing member 101. When the blocking structure 53 includes the fixing block 531, the first connecting structure 5311 is connected to the fixing block 531.

[0069] Furthermore, both the first connecting structure 5311 and the second connecting structure 1012 can be rod-shaped structures. Of course, the first connecting structure 5311 and the second connecting structure 1012 can also be other types, for example, both the first connecting structure 5311 and the second connecting structure 1012 can be cylindrical structures. In this regard, the embodiments of this application do not limit the scope of the application.

[0070] In addition, in some embodiments, the first end of the sliding bracket 52 is provided with a through hole 521, and the sliding rod 51 passes through the through hole 521 so that the first end of the sliding bracket 52 is slidably connected to the sliding rod 51.

[0071] Since the first end of the sliding bracket 52 is provided with a through hole 521, the sliding rod 51 can be inserted through the through hole 521, thereby realizing the sliding connection between the first end of the sliding bracket 52 and the sliding rod 51. Furthermore, it can ensure that the sliding bracket 52 is not easily separated from the sliding rod 51, which makes it easier for the sliding bracket 52 to drive the blocking member 532 to move for a longer period of time.

[0072] Of course, in this embodiment, the sliding connection between the first end of the sliding bracket 52 and the sliding rod 51 can also be in other ways. For example, the outer wall of the sliding rod 51 is provided with a groove, and the first end of the sliding bracket 52 is provided with a slider that can be embedded in the groove, thereby realizing the sliding connection between the sliding bracket 52 and the sliding rod 51. This embodiment does not limit the specific method of sliding connection between the sliding bracket 52 and the sliding rod 51.

[0073] Additionally, in some embodiments, such as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the second end of the sliding bracket 52 is provided with a through groove 522. The blocking member 532 includes a blocking body 5321, a connecting rod 5322, and a blocking block 5323. One end of the connecting rod 5322 is connected to the blocking body 5321, and the other end of the connecting rod 5322 is connected to the blocking block 5323. The blocking body 5321 is slidably connected to the fixed block 531. The connecting rod 5322 passes through the through groove 522, and the width of the blocking block 5323 is greater than the width of the through groove 522, so that the second end of the sliding bracket 52 is slidably connected to the blocking member 532.

[0074] Since one end of the connecting rod 5322 is connected to the blocking body 5321 and the other end is connected to the blocking block 5323, and the blocking body 5321 is slidably connected to the fixed block 531, the connecting rod 5322 can be connected to the sliding bracket 52, allowing the sliding bracket 52 to drive the blocking body 5321 to move along the second direction Y via the connecting rod 5322. This causes the blocking plate to move above the limiting member 201, whereby the blocking body 5321 blocks the limiting member 201, preventing it from lifting in the first direction X. Furthermore, the second end of the sliding bracket 52 is provided with a through groove 522. Therefore, when connecting the sliding bracket 52 to the blocking member 532, the connecting rod 5322 can pass through the through groove 522, facilitating the connection between the sliding bracket 52 and the blocking member 532. In addition, the width of the blocking block 5323 is greater than the width of the through groove 522, so that after the connecting rod 5322 passes through the through groove 522, the blocking block 5323 can effectively block the sliding bracket 52, thus preventing the sliding bracket 52 from separating from the connecting rod 5322.

[0075] It should be noted that the blocking block 5323 and the connecting rod 5322 are detachably connected. Therefore, when the connecting rod 5322 needs to pass through the through slot 522 at the second end of the sliding bracket 52, the blocking block 5323 and the connecting rod 5322 can be separated, the connecting rod 5322 can be passed through the through slot 522, and then the blocking block 5323 and the connecting rod 5322 can be connected. The blocking block 5323 and the connecting rod 5322 can be connected by threads.

[0076] Furthermore, the shape of the blocking block 5323 can be set according to actual needs. For example, the blocking block 5323 can be disc-shaped, or it can be cuboid-shaped. This embodiment of the application does not limit the specific shape of the blocking block 5323.
