The anti-skid device includes a base, a stop member rotatably disposed on the base so as to be switchable between a first state in which the stop member is positioned in a path of movement of the object to block displacement of the object and a second state in which the stop member is withdrawn from the path of movement of the object to allow displacement of the object, and a locking mechanism that is capable of locking the stop member in the second state relative to the base.

Description

Technical Field

[0001] This utility model relates to an anti-slip device. Background Technology

[0002] During the loading and unloading operations of large-mass, large-volume cargo containers or equipment such as large containers and auxiliary fuel tanks on civil aircraft, it is necessary to effectively control the movement path and real-time position of the cargo containers.

[0003] This is because, before the cargo container reaches its locked position, it may slide unexpectedly due to sudden adjustments in the aircraft's attitude (such as tilting caused by ground wind, load changes, or temporary support equipment), accidental collisions by personnel, or operational errors. This can lead to damage to the cargo container, equipment, and aircraft structure, and even affect personnel safety. Especially during the brief period when the cargo container is at the hatch door, it is easily swayed by the aircraft and may even slide out of the hatch, causing damage to the container and the cargo inside. Furthermore, a sliding cargo container may collide with the hatch door frame, damaging the door frame structure and incurring additional repair costs.

[0004] Therefore, when loading and unloading these large cargo containers, anti-slip devices are usually installed along their loading and unloading paths. Currently, these anti-slip devices mostly use stoppers to restrict the movement of the container in one direction to achieve the anti-slip effect. For example, when a worker steps on the stopper, it allows the container to pass over it. After the container has passed, the worker stops stepping on the stopper, and at this point, the stopper returns to its state of restricting the movement of the container in one direction, thus temporarily limiting the container's movement. When it is necessary to release this temporary restriction and move the container further, the stopper can be operated in the same way as described above, and the container can be moved.

[0005] However, when operating the existing anti-slip device, one worker needs to stand near the device to operate the stop block before the cargo box passes over it, while another worker moves the cargo box, reducing labor efficiency. Furthermore, moving the cargo box requires constant attention to the workers, which affects work efficiency, and the cargo box may collide with workers in case of operational errors, posing a safety hazard. Utility Model Content

[0006] This utility model was made in view of the above-mentioned problems, and its purpose is to provide an anti-slip device that does not require operation by a person nearby when an object moves on the anti-slip device.

[0007] To achieve the above objectives, the present invention provides an anti-slip device comprising: a base; a stop member rotatably disposed on the base, thereby switching between a first state in which the object is located in the movement path of the object to prevent displacement of the object and a second state in which the object is retracted from the movement path of the object to allow displacement of the object; and a locking mechanism capable of locking the stop member in the second state relative to the base.

[0008] According to this utility model, the anti-slip device can lock the stop in a state that allows the object to move through a locking mechanism. Therefore, when moving objects such as cargo boxes to a temporary position or from a temporary position and moving further, workers only need to lock the stop using the locking mechanism before moving the cargo box to move away from the anti-slip device. During the movement of the cargo box, no workers need to operate near the anti-slip device. Thus, compared to the previous method requiring at least two people, this effectively improves manpower efficiency. Furthermore, since no one needs to stand near the anti-slip device during the movement of the cargo box, the risk of accidental injury is reduced, improving both operational efficiency and safety.

[0009] Furthermore, in the anti-slip device of this utility model, preferably, the locking mechanism can also lock the stop member in the first state.

[0010] According to the anti-slip device with the above structure, the stop can also be locked in a state that restricts the displacement of the object through the locking mechanism, thereby preventing the stop from rotating and releasing the state that restricts the displacement of the object due to the operator's misoperation, thus improving the safety and reliability of the anti-slip device.

[0011] Furthermore, in the anti-slip device of this utility model, it is preferred to include an elastic element connected to the stop member. The stop member switches to the first state by rotating upward and to the second state by rotating downward. The elastic element provides an upward torque to the stop member.

[0012] According to the anti-slip device with the above structure, the elastic element provides an upward torque to the stop member, so that the stop member can automatically rotate upward to switch to the first state without being subjected to other forces. Thus, for example, after the locking mechanism releases the lock on the stop member in the second state, the stop member can automatically return to the first state to limit the displacement of the object, thereby simplifying the operation of the anti-slip device.

[0013] Furthermore, in the anti-slip device of this utility model, it is preferable that a limiting member is provided on the base, and the limiting member restricts the stop member from rotating further upward so that the stop member remains in the first state.

[0014] Furthermore, in the anti-slip device of this utility model, it is preferable that the limiting member is integrally formed with the base.

[0015] According to the anti-slip device with the above structure, the stop can be kept in the first state by the limiting member, thereby simplifying the operation of making the stop restrict the displacement of the object. Since the limiting member is integrally formed with the base, the number of components constituting the device can be reduced, thereby reducing the manufacturing cost.

[0016] Furthermore, in the anti-slip device of this invention, it is preferred to include a rolling element, wherein the object can contact the rolling element and move relative to the rolling element in a manner with rolling friction.

[0017] According to the anti-slip device with the above structure, the object can be moved relative to the rolling element in a manner with rolling friction, thereby reducing the force required for the object to move relative to the anti-slip device and improving the comfort of operation.

[0018] Furthermore, in the anti-slip device of this utility model, preferably, the locking mechanism includes an operating member and a locking member. The operating member is connected to the stop member and can drive the stop member to rotate by operating the operating member. The locking member moves integrally with the operating member and is fixed to the base so as to lock the stop member in the first state or the second state via the operating member.

[0019] According to the above-described anti-slip device, the operating component in the locking mechanism can drive the stop to rotate, and the locking component can lock the stop via the operating component. Thus, the operator can switch the state of the stop and lock it by simply operating the locking mechanism, which simplifies the structure of the device, thereby simplifying the operation process and improving the operability of the device.

[0020] (Utility Model Effect)

[0021] According to this utility model, the anti-slip device can lock the stop in a second state that allows the object to move through a locking mechanism. Therefore, when moving objects such as cargo boxes to a temporary position or from a temporary position and moving further, workers only need to lock the stop using the locking mechanism before moving the cargo box to move away from the anti-slip device. During the movement of the cargo box, no workers need to operate near the anti-slip device. Thus, compared to the previous method requiring at least two people, this effectively improves manpower efficiency. Furthermore, since no one needs to stand near the anti-slip device during the movement of the cargo box, the risk of accidental injury is reduced, improving both operational efficiency and safety.

[0022] In addition, the locking mechanism can lock the stop in the first state that restricts the displacement of the object, thereby preventing the stop from being released from its limit on the object due to misoperation.

[0023] Furthermore, through the cooperation of the elastic element and the limiting element on the base, the stop element can automatically return to and lock back to the first state when the lock is released, thereby simplifying the operation of the device. Moreover, the stop element can be operated and locked by the locking mechanism, which simplifies the structure of the device, streamlines the operation process, and improves operability.

[0060] The anti-slip device of one embodiment of the present invention will now be described with reference to the accompanying drawings.

[0061] Figure 1 This is a perspective view showing the structure of the anti-slip device according to this embodiment. Figure 1 As shown, the anti-slip device of this embodiment mainly includes a base 1 and a stop mechanism 20 and a locking mechanism 30 installed on the base 1.

[0062] For ease of explanation, the following will be used as... Figure 1 The length of the base 1 is defined as the left-right direction, the width of the base 1 as the front-back direction, and the height of the base 1 as the up-down direction.

[0063] Figure 2The structure of the base 1 of the anti-slip device according to this embodiment is shown. The base 1 of this embodiment is, for example, made of a high-strength metal, such as... Figure 2 As shown, the base 1 is integrally formed into a slot shape, having a base plate and a front plate and a rear plate that extend upwards from the front and rear ends of the base plate and are integrally formed with the base plate.

[0064] When viewed vertically, the base plate is rectangular in shape, with square through holes at the center of the left-right and front-back directions for mounting the intermediate arm of the torsion spring 3 (described later). Additionally, circular through holes are provided on both sides of the square through holes, allowing the base 1 to be fixed to the predetermined mounting position by passing bolts or other fasteners through these holes. This prevents the anti-slip device from losing its anti-slip effect due to the base 1 sliding during use.

[0065] The front and rear panels have the same shape when viewed in the front-rear direction. Their upper edges have a horizontally extending portion and portions extending obliquely downward on the left and right sides of the horizontally extending portion. Hereinafter, the horizontally extending portion of the upper edge is sometimes referred to as the flat edge, and the obliquely extending portions on the left and right sides are referred to as the left oblique edge and the right oblique edge.

[0066] like Figure 1 As shown, flanges 15 are formed on the flat edges of the front and rear panels respectively. These two flanges 15 are formed at the same position in the left-right direction and protrude and extend from the front and rear panels in a way that they are close to each other in the front-back direction.

[0067] The two flanges 15 are formed with the same shape. In this embodiment, when viewed from the front, the upper end faces of the two flanges 15 are flush with the aforementioned flat flange, and the lower end faces are inclined to the lower right. The two flanges 15 abut against the stop block 2 in the stop mechanism 20 (described later) through their lower end faces to limit the stop block 2. Hereinafter, the lower end faces of the flanges 15 are sometimes referred to as the limiting faces. The specific form of limiting the stop block 2 through the limiting faces will be described in detail later.

[0068] In addition, such as Figure 1 As shown, pin mounting holes 14 are provided on the front and rear plates respectively. The pin mounting holes 14 are located on the right side of the flange 15 in the front-rear direction, so that the first pin 4 described later can pass through and support it.

[0069] Additionally, the front panel has a lever mounting hole 16 for mounting the locking mechanism 30, as well as upper and lower latching holes 17 and 18 arranged vertically. The structure of these holes and the specific mounting configuration of the locking mechanism 30 will be described in detail later.

[0070] In addition, such as Figure 5 , Figure 6As shown, a soft pad 7 is also provided on the upper surface of the base plate of the base 1. The soft pad 7 is used to prevent the stop block 2 of the stop mechanism 20 described later from directly contacting the base plate and causing wear.

[0071] Figure 3 The structure of the stop mechanism 20 in this embodiment is shown. Figure 4 The components constituting the stop mechanism 20 are shown disassembled. Figure 5 The anti-slip device is shown without the locking mechanism 30 installed. Figure 6 Will constitute Figure 5 The components of the anti-slip device are shown disassembled.

[0072] like Figures 3 to 5 As shown, the stopping mechanism 20 of this embodiment mainly includes a stopping block 2, a torsion spring 3, a first pin 4, a second pin 5, and a roller 6.

[0073] The stop block 2 is a major component of the stop mechanism 20, such as... Figure 2 As shown, the stop block 2 has a stop part 21, a roller mounting part 22, and a base mounting part 23.

[0074] The stop part 21 is the part of the stop block 2 used to prevent objects such as cargo boxes from sliding. Specifically, the left end face of the stop part 21 can abut against objects such as cargo boxes, and the cargo box 40 is limited by the fixed base 1. The surface of the stop part 21 that abuts against the cargo box 40 shown below will also be called the limiting surface.

[0075] Furthermore, in this embodiment, such as Figure 3 As shown, the limiting surface on the stop part 21 is a plane, but the shape of the limiting surface is not limited to a plane, and it can be appropriately changed according to the shape of the cargo box 40, which is the object of the anti-slip device.

[0076] The roller mounting part 22 is the portion of the stop block 2 used to mount the roller 6. For example... Figure 4 As shown, the roller mounting part 22 is provided with two lugs arranged parallel to each other in the front-rear direction, and the distance between the two lugs is sufficient for the roller 6 to be inserted. The two lugs are provided with mounting holes for the second pin 5, through which the second pin 5 passes to support the roller 6 between the two lugs.

[0077] In addition, such as Figure 3 , Figure 4 As shown, the roller mounting part 22 also includes two grooves. These two grooves extend from the front and rear end faces of the stop block 2 in the front and rear directions to the front and rear lugs, respectively, thereby forming a storage space on the front side of the front lug and the rear side of the rear lug, for storing the second pin 5 (specifically the head of the second pin 5), the nut 12 for fastening the second pin 5, and the washer 13 between the second pin 5, the nut 12 and the front and rear lugs.

[0078] The base mounting part 23 is used to mount the stop block 2 to the base 1. For example... Figure 3 , Figure 4 As shown, the base mounting part 23 has two connecting arms, front and rear, which are formed to protrude from the right end face of the stop block 2 and are arranged at intervals in the front-rear direction.

[0079] The front and rear connecting arms are provided with pin mounting holes 24 for mounting the first pin 4, and the rod part of the first pin 4 can pass through the pin mounting holes 24.

[0080] The front and rear connecting arms are also provided with torsion spring insertion holes 25 for mounting torsion spring 3. Specifically, the torsion spring insertion hole 25 allows at least one end of the torsion arm of the torsion spring 3 to be inserted. By inserting the torsion arm of the torsion spring 3 into the torsion spring insertion hole 25, the torsion arm of the torsion spring 3 is connected to the stop block 2, thereby driving the stop block 2 to rotate through the torque of the torsion spring 3.

[0081] Additionally, the stop block 2 is provided with an operating rod mounting hole 26, which is used for the operating rod 8 in the locking mechanism 30 described later to be inserted, so as to drive the stop block 2 to rotate through the operating rod 8.

[0082] The second pin 5 is formed in the shape of a bolt, having a head and a shank, with an external thread at one end of the shank (the rear end in the figure). The nut 12 is, for example, a self-locking nut, which can mate with the external thread and be installed. Furthermore, when the second pin 5 and the nut 12 are installed to the stop block 2, washers 13 are provided at the head of the second pin 5 and between the nut 12 and the front and rear lugs, respectively, to distribute the stress exerted on the lugs by the second pin 5 and the nut 12 and prevent damage to the lugs.

[0083] The roller 6 is integrally formed into a cylindrical shape. By aligning the through hole in its center with the through holes on the two lugs of the roller mounting part 22, and passing the second pin 5 through these through holes, and then tightening it with the nut 12, the roller 6 is mounted onto the stop block 2.

[0084] With the roller 6 installed on the stop block 2, the roller 6, supported by the second pin 5, can rotate around the second pin 5. Therefore, when moving the cargo box 40 above the anti-slip device of this embodiment, the bottom surface of the cargo box 40 can be pressed onto the roller 6 and pushed along with the rotation of the roller 6, thereby moving the cargo box 40 with less effort.

[0085] In addition, although not shown, the radial outer circumference of the roller 6 is covered with rubber, which can appropriately increase the friction between the bottom surface of the cargo box 40 and the roller 6, thereby helping to push the cargo box 40 with the rotation of the roller 6 to achieve a labor-saving effect.

[0086] like Figure 6As shown, the first pin 4 in this embodiment has pin holes at both ends in the length direction for inserting cotter pins 11. The first pin 4 can be inserted into the pin mounting hole 14 on the base 1 and the pin mounting hole 24 on the stop block 2 to connect the stop block 2 to the base 1.

[0087] The torsion spring 3 in this embodiment is a so-called double torsion spring, such as... Figure 5 as well as Figure 6 As shown, it has two wound springs and an intermediate arm connecting the two springs. The first pin 4 can be inserted into the hollow part of the two springs of the torsion spring 3, thereby supporting the spring part of the torsion spring 3.

[0088] As described above, the middle arm of the torsion spring 3 is mounted in the square through hole on the base 1. In addition, at least one of the torsion arms at the ends of the two springs on the torsion spring 3 that are not connected to each other can be inserted into the torsion spring socket 25 on the stop block 2.

[0089] Specifically, in this embodiment, the torsion arm at the front end of the torsion spring 3 is inserted into the torsion spring insertion hole 25 on the front connecting arm of the stop block 2, and the torsion arm at the rear end of the torsion spring 3 abuts against the rear connecting arm of the stop block 2 (see reference). Figure 5 Therefore, the torsion spring 3 can be supported by the torsion spring socket 25, and the torque of the torsion spring 3 can be transmitted to the stop block 2.

[0090] The following describes how the stop mechanism 20 is installed onto the base 1.

[0091] Before installing the stop mechanism 20 onto the base 1, the roller 6 is first installed onto the stop block 2 in the manner described above using the second pin 5, nut 12, and washer 13.

[0092] Next, insert the torsion arm at the front end of the torsion spring 3 into the torsion spring socket 25 on the front connecting arm of the stop block 2, and make the torsion arm at the rear end of the torsion spring 3 abut against the rear connecting arm of the stop block 2, thereby installing the torsion spring 3 onto the stop block 2.

[0093] Then, as Figure 5 , Figure 6 As shown, two bushings 10 are installed into the pin mounting holes 24 on the stop block 2 from the front and rear, respectively. Specifically, the bushings 10 are so-called T-shaped bushings (flange bushings), with the bushing portion embedded in the pin mounting hole 24 and the flange portion abutting against the front end face of the front connecting arm and the rear end face of the rear connecting arm of the stop block 2, respectively.

[0094] Then, the assembly consisting of the stop block 2, which is equipped with the torsion spring 3, the roller 6, and the bushing 10, is placed into the base 1. Specifically, the assembly is inserted into the base 1 from the left side, so that the stop portion 21 of the stop block 2 is located to the left of the two flanges 15 on the base 1, and the upper end face of the part of the stop block 2 other than the stop portion 21 is located below the lower end face (limiting surface) of the flange 15. The middle arm of the torsion spring 3 is then placed into the square through hole in the bottom plate of the base 1.

[0095] Finally, align the pin mounting hole 14 on the base 1 with the pin mounting hole 24 on the stop block 2, and pass the first pin 4 through the bushing 10 in the pin mounting hole 14 and the pin mounting hole 24 until the two pin holes of the first pin 4 are located on the front and rear sides respectively relative to the base 1. Then, insert the cotter pin 11 into the pin hole on the first pin 4 to fix the first pin 4.

[0096] The above completes the installation of the stop mechanism 20 onto the base 1.

[0097] Figure 7 The anti-slip device with the locking mechanism 30 installed is shown, and the components constituting the locking mechanism 30 are shown individually. Figure 7 As shown, the locking mechanism 30 of this embodiment includes an operating lever 8 and a latch 9.

[0098] The operating lever 8 has an operating part and a lever part. An external thread is formed on the end of the lever part away from the operating part. An internal thread matching the external thread is formed in the hole of the operating lever mounting hole 26 on the stop block 2, so that the operating lever 8 can be installed to the stop block 2.

[0099] The latch 9 is a component used to lock the operating lever 8. A through hole is formed on the latch 9 for the rod portion of the operating lever 8 to pass through. The latch 9 is installed on the operating lever 8 by fitting the latch 9 onto the rod portion of the operating lever 8.

[0100] Two cylindrical pins are provided on the end face of the latch 9 that is orthogonal to the axis of the through hole. These two pins are used to insert into the upper latch hole 17 or the lower latch hole 18 on the base 1.

[0101] Furthermore, in this embodiment, the latch 9 is mounted on the operating lever 8 in a manner that restricts rotation. Specifically, the lever portion of the operating lever 8 is formed into an elongated oval shape, and the through hole on the latch 9 is formed into an elongated oval shape slightly larger than the shape of the operating lever 8, or a rectangular shape whose four sides are tangent to the elongated oval shape of the operating lever 8. Thus, when the latch 9 is fitted onto the operating lever 8, the rotation of the latch 9 is restricted by the combination of the above shapes, and the posture of the latch 9 relative to the operating lever 8 is fixed.

[0102] In addition, although the latch 9 cannot rotate relative to the operating lever 8, it can move along the rod of the operating lever 8.

[0103] The following describes the installation method of the locking mechanism 30.

[0104] First, insert the operating lever 8 into the through hole on the latch 9. At this time, the operating lever 8 is inserted into the latch 9 from the side without the pin. That is, when the operating lever 8 is inserted into the latch 9, the head of the operating lever 8 and the pin on the latch 9 should be on opposite sides of the main body of the latch 9.

[0105] After installing the stop mechanism 20 onto the base 1 as described above, insert the operating rod 8, which is equipped with the latch 9, into the operating rod mounting hole 26 on the stop block 2 through the operating rod mounting hole 16 on the base 1, and screw the operating rod 8 to install it onto the stop block 2 via threaded engagement. Thus, by operating the operating rod 8, the stop block 2 can be rotated around the first pin 4.

[0106] Specifically, such as Figure 8 As shown, when viewed in the front-to-back direction, the operating rod mounting hole 16 on the base 1 is formed into an elongated oval shape. Specifically, its left and right edges are formed into arcs with the center of the pin mounting hole 14 as the center. Therefore, the operating rod mounting hole 16 is formed to extend arc-shaped in the vertical direction with the center of the pin mounting hole 14 as the center.

[0107] Therefore, when the operating lever 8 is inserted into the operating lever mounting hole 16, it can move along an arc-shaped path and drive the stop block 2 to rotate around the first pin 4.

[0108] The working principle of the anti-slip device in this embodiment will be explained below.

[0109] Figure 9 The working state of the anti-slip device of this embodiment is schematically shown. Among them, Figure 9 (a) shows the state before the container 40 is moved to the temporary position. Figure 9 (b) shows the state during the process of moving container 40 to a temporary location. Figure 9 (c) shows the state after the container 40 has been moved to a temporary position, where the temporary position refers to the location where the container 40 is temporarily placed before being moved to the target position. Furthermore, Figure 9 The hollow arrows shown in (a), (b), and (c) are used to indicate the direction of movement of cargo box 40.

[0110] like Figure 9As shown in (a), before the cargo box 40 begins to move, the anti-slip device's stop mechanism 20 is in a first state. In this first state, the stop block 2 of the stop mechanism 20 is subjected to a clockwise torque around the first pin 4 under the preload of the torsion spring 3, resulting in the stop block 2 rotating upwards. At this time, the upper end face of the stop block 2 (specifically, the upper end face of the portion located on the right side of the roller 6) abuts against the flange 15 on the base 1, thereby limiting the stop block 2 by the flange 15 to prevent it from rotating further clockwise.

[0111] In addition, such as Figure 9 As shown in (a), in this first state, the stop surface (i.e., the left end face) of the stop block 2 is perpendicular to the left-right direction. In other words, when the base 1 is mounted on the mounting surface at the predetermined mounting position, the braking surface of the stop block 2 is perpendicular to the mounting surface. It should be understood that the predetermined mounting position mentioned here is a position near the aforementioned temporary position.

[0112] At this time, when viewed in the front-to-back direction, the latch 9 in the locking mechanism 30 coincides with the upper latch insertion hole 17 of the base 1, but the latch 9 is not inserted into the upper latch insertion hole 17.

[0113] Furthermore, the posture of the stop block 2 when it is limited by the flange 15 can be changed by altering the tilt angle of the limiting surface of the flange 15. Specifically, for example, the angle of the limiting surface can be changed by installing a pad on the limiting surface of the flange 15, thereby changing the posture of the stop block 2 of the stop mechanism 20 in the first state.

[0114] Next, as Figure 9 As shown in (b), during the movement of the cargo box 40, the stop block 2 of the stop mechanism 20 rotates downward due to the pressure from above by the cargo box 40, thereby changing the stop mechanism 20 to the second state.

[0115] Specifically, during this process, as the cargo box 40 moves in the direction of movement, it first contacts the roller 6 mounted on the stop block 2. The roller 6 experiences rolling friction with the bottom surface of the cargo box 40, facilitating its continued movement. Simultaneously, the cargo box 40 applies downward pressure to the stop block 2 via the roller 6. The torque generated by this pressure overcomes the preload torque of the torsion spring 3, causing the stop block 2 to rotate counterclockwise around the first pin 4. As a result, the stop block 2 rotates downward to a predetermined position, and the stop mechanism 20 changes to its second state.

[0116] At this time, the stop part 21 of the stop block 2 is located below the bottom plate of the cargo box 40, and more specifically, below the flat edges of the front and rear plates of the base 1. Therefore, the stop part 21 of the stop block 2 will not obstruct the movement of the cargo box 40.

[0117] Furthermore, at this time, when viewed in the front-to-back direction, the latch 9 in the locking mechanism 30 coincides with the lower latch insertion hole 18 of the base 1, but the latch 9 is not inserted into the lower latch insertion hole 18.

[0118] Next, as Figure 9 As shown in (c), after the movable cargo box 40 moves to the temporary position, the stop block 2 of the stop mechanism 20 is no longer pressed by the cargo box 40 and rotates upward again, so that the stop mechanism 20 returns to the first state.

[0119] At this time, since the stop surface of the stop block 2 also returns to a state perpendicular to the mounting surface of the predetermined installation position (near the temporary position), when the cargo box 40 tries to slide in the opposite direction due to unexpected situations such as aircraft shaking, the stop surface can prevent the cargo box 40 from sliding, thereby achieving an anti-slip effect.

[0120] When it is necessary to move the cargo box 40 from the temporary position to the target position, the stop mechanism 20 must first be changed to the second state so that the stop part 21 of the stop block 2 no longer obstructs the movement of the cargo box 40.

[0121] Figure 10 This shows the state in which the locking mechanism 30 locks the stop mechanism 20 in the second state. Figure 10 The locking buckle hole 17 is omitted. For example... Figure 10 As shown, loading and unloading personnel and other staff press down the operating lever 8, causing the stop block 2 to rotate downwards until the stop mechanism 20 changes to the second state. Then, they push the latch 9 backwards along the operating lever 8 to insert the latch 9 pin into the lower latch hole 18 of the base 1.

[0122] Thus, the locking mechanism 30 is in a locked state, which locks the stop mechanism 20 in the second state. As described above, since the stop part 21 of the stop block 2 is in a position that does not obstruct the movement of the cargo box 40, the cargo box 40 can be easily moved above the roller 6 and the cargo box 40 can be moved continuously until it is disengaged from the anti-slip device.

[0123] Compared with existing anti-slip devices, in the above process, an operator only needs to operate the stop mechanism 20 to the second state via the operating lever 8, and then push the pin of the latch 9 into the lower latch hole 18 of the base 1 to lock the stop mechanism 20 in the second state. Then the operator can leave the vicinity of the anti-slip device and the cargo box 40 and continue to operate the moving cargo box 40.

[0124] Therefore, compared to situations requiring at least two people to operate, it effectively improves manpower efficiency, and no one needs to stand near the anti-slip device to operate in the moving cargo box 40, reducing the risk of accidental injury to people during the movement of the cargo box 40, and improving operational efficiency and safety.

[0125] Furthermore, after the above process is completed, simply pull the pin of the latch 9 out of the lower latch hole 18 to release the lock on the stop mechanism 20 and restore it to the first state.

[0126] In addition, when the stop mechanism 20 is in the first state and limits the cargo box 40 in the temporary position, the latch 9 can be pushed backward along the operating lever 8 to insert the pin of the latch 9 into the upper latch socket 17 of the base 1.

[0127] Thus, the locking mechanism 30 locks the stop mechanism 20 in the first state. Even if, for example, a worker accidentally steps on the stop mechanism 20, the stop mechanism 20 is locked in the first state, which can prevent the stop mechanism 20 from accidentally releasing its limit on the cargo box 40, causing the cargo box 40 to slide and injure the worker.

[0128] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above embodiments.

[0129] For example, in the above embodiment, the locking mechanism 30 can lock the stop mechanism 20 in the first and second states, but it is not limited to this. For example, the stop mechanism 20 can be locked in the second state by only providing the lower locking hole 18 on the base 1, or the stop mechanism 20 can be locked in a third state different from the first and second states by providing another locking hole between the upper locking hole 17 and the lower locking hole 18 on the base 1. The stop mechanism 20 can also be locked in three or more different states in the same way.

[0130] Therefore, the stop part of the stop block 2 and the height of the roller 6 set on the stop block 2 can be appropriately adjusted according to factors such as the shape and placement height of the cargo box 40.

[0131] Furthermore, in the above embodiment, cylindrical rollers 6 are provided on the stop block 2 to facilitate the movement of the cargo box 40, but this is not a limitation. For example, a conveyor belt-like structure can be provided on the stop block 2 to reduce the difficulty of moving the cargo box 40, or a structure with multiple rollers 6 arranged in the left-right direction can be used.

[0132] Furthermore, in the above embodiment, the latch 9 of the locking mechanism 30 is locked by inserting an integrally formed pin into a socket on the base 1, but this is not a limitation. To improve locking reliability, for example, a socket for fastener insertion can be provided on the latch 9, and locking can be achieved by the fastener passing through this socket and the sockets on the base 1 (upper latch socket 17, lower latch socket 18). In this case, the latch 9 may not need to be movable along the operating lever 8, and for example, the latch 9 can be integrally formed with the operating lever 8.

[0133] Furthermore, the connection method between the operating lever 8 and the stop block 2 is not limited to the threaded connection described above. For example, when the operating lever 8 and the latch 9 are integrally formed, the unthreaded lever portion can be movably inserted into the operating lever mounting hole on the unthreaded stop block 2. In this case, the operating part of the operating lever 8 can also be shaped like, for example, a bicycle pedal. The operator can press down on the operating part to switch the stop mechanism 20 to the second state and apply force towards the base 1 to insert the pin of the latch 9 to achieve locking. As a result, the operator can complete the operation without bending over, improving the comfort of operating the device.

[0134] It should be understood that within the scope of this utility model, the various parts in the embodiments can be freely combined, or the various parts in the embodiments can be appropriately modified or omitted.
