[0037] The anti-skid mechanism of the first aspect of the present utility model is described below with reference to the accompanying drawings of the present specification. It should be noted that, in the embodiments of the present utility model, the downward direction is shown as the first direction, and the leftward-rightward direction is shown as the second direction for the convenience of understanding and description.

[0038] The present utility model embodiment provides a kind of for fixing transfer car's anti-skid mechanism 100, refer to Figures 1 to 3 As shown in the figure, the anti-skid mechanism 100 includes base 110, elastic member 120, locking member 130 and movable assembly 140, wherein the base 110 includes the upper plate body 111 and the lower plate body 112 connected, the connecting place of the upper plate body 111 and the lower plate body 112 has rotation axis, the upper plate body 111 can be rotated relative to the lower plate body 112 around the rotation axis of connecting place, so that the upper plate body 111 has first position and second position, the upper plate body 111 can be switched between first position and second position, make the anti-skid mechanism 100 have different use state. The two ends of elastic member 120 are connected to the upper plate body 111 and the lower plate body 112 respectively, and elastic member 120 is disposed between the upper plate body 111 and the lower plate body 112 along the first direction, and elastic member 120 is used to lift the upper plate body 111, so that the upper plate body 111 is rotated relative to the lower plate body 112 around the rotation axis to fix transfer car. Locking member 130 is connected to the lower plate body 112, and locking member 130 is used to abut the upper plate body 111, and is compressed with the upper plate body 111 together elastic member 120, so that elastic member 120 cannot lift the upper plate body 111. Wherein, locking member 130 can be moved relative to the upper plate body 111 along the second direction to separate from the upper plate body 111. When locking member 130 and the upper plate body 111 separate, the upper plate body 111 will be lifted under the action of elastic member 120. Movable assembly 140 is used to drive locking member 130 to move. Movable assembly 140 connects the lower plate body 112 and locking member 130, and movable assembly 140 can move relative to the lower plate body 112, so as to drive locking member 130 to move to separate from the upper plate body 111.

[0039] Specifically, in one of the embodiments, the upper plate body 111 is rotated relative to the lower plate body 112 to have first position and second position. Refer to Figure 2As shown, when the upper plate body 111 is in the first position, the locking member 130 abuts against the lower plate body 112 to fix the lower plate body 112. The locking member 130 and the lower plate body 112 jointly compress the elastic member 120, so that the elastic member 120 cannot lift the upper plate body 111. At this time, the transfer trolley can be moved and transported from above the skid prevention mechanism 100. Moreover, when the skid prevention mechanism 100 is not used, the upper plate body 111 in the first position can also facilitate the storage of the skid prevention mechanism 100.

[0040] When it is necessary to fix the transfer trolley, the skid prevention mechanism 100 is arranged below the transfer trolley. The locking member 130 can be driven by the movable assembly 140 to move relative to the upper plate body 111, so that the upper plate body 111 and the locking member 130 are separated, and at this time the upper plate body 111 is lifted in the first direction to contact the transfer trolley. Referring to Figure 1 As shown, when the upper plate body 111 is switched from the first position to the second position, under the action of the elastic force of the elastic member 120, the upper plate body 111 is subjected to an upward elastic force, so that the upper plate body 111 is rotated and lifted relative to the lower plate body 112 until the upper plate body 111 abuts against the lower side of the transfer trolley. Due to the elastic force, the upper plate body 111 always abuts against the transfer trolley, thereby achieving the fixation of the transfer trolley.

[0041] In the related art, when the transfer trolley is loaded on the truck by lifting the tail plate, the tail plate will be inclined relative to the ground, thereby causing the transfer trolley to have the risk of sliding and falling off the tail plate. Therefore, in the related art, two people are often needed to cooperate, one of whom controls the lifting of the tail plate, and the other supports the transfer trolley to complete the loading and unloading of the transfer trolley. However, this will consume more manpower for loading the transfer trolley, and if the transfer trolley slips during loading, there is a risk of injury to personnel, and the safety is low.

[0042] Compared with the related art, the skid prevention mechanism 100 of the utility model embodiment abuts the upper plate body 111 by the locking member 130, the locking member 130 and the upper plate body 111 jointly compress the spring, so that the upper plate body 111 avoids the transfer trolley, thereby enabling the transfer trolley to normally pass through the skid prevention mechanism 100 when the tail plate is lifted to the specified position, to complete the loading or unloading of the transfer trolley. When the tail plate is lifted, the skid prevention mechanism 100 drives the locking member 130 to move by the movable assembly 140, so that the locking member 130 is separated from the upper plate body 111, the upper plate body 111 is lifted under the action of the elastic member 120 to abut against the transfer trolley, to fix the transfer trolley, avoid the transfer trolley from sliding and falling off the tail plate, and improve the safety of loading and unloading the transfer trolley.

[0043] In some embodiments, referring to Figure 1 and Figure 2As shown, the movable assembly 140 comprises a movable rod 141 and a pull rod 142 connected together, wherein the movable rod 141 is movably connected to the lower plate body 112, i.e. the movable rod 141 can move relative to the lower plate body 112. The pull rod 142 is connected to the locking member 130 and the movable rod 141 respectively. Specifically, in this embodiment, one end of the pull rod 142 is connected to the locking member 130, and the other end is connected to the movable rod 141. When the movable rod 141 moves relative to the lower plate body 112, the movable rod 141 can drive the pull rod 142 to move in the second direction, so as to drive the locking member 130 to move in the second direction to separate from the upper plate body 111, so as to realize the lifting of the upper plate body 111. When the transfer trolley is placed above the anti-skid mechanism 100, the upper plate body 111 can be brought into contact with the transfer trolley by driving the movable rod 141, so as to realize the fixation of the transfer trolley, so that the operation of fixing the transfer trolley by the anti-skid mechanism 100 is more simple and convenient, and the fixing efficiency of the anti-skid mechanism 100 is improved.

[0044] Further, in some embodiments, the movable rod 141 is slidingly connected to the lower plate body 112. Specifically, the side of the lower plate body 112 facing the movable rod 141 is provided with a sliding rail arranged in the second direction, and the movable rod 141 is connected to the sliding rail. When the upper plate body 111 needs to be switched from the first position to the second position to fix the transfer trolley, the movable rod 141 is pushed to slide in the second direction in the sliding rail relative to the lower plate body 112, so as to drive the pull rod 142 and the locking member 130 to move in the second direction, so that the elastic member 120 lifts the upper plate body 111, thereby realizing the fixation of the transfer trolley.

[0045] In another embodiment, the movable rod 141 is rotatably connected to the lower plate body 112 (e.g. hinged). Specifically, the connection between the movable rod 141 and the lower plate body 112 has an axis of rotation, and the movable rod 141 can rotate relative to the lower plate body 112 about the axis of rotation. Since the pull rod 142 is connected to the movable rod 141, when the movable rod 141 rotates relative to the lower plate body 112, the connection position of the pull rod 142 and the movable rod 141 will change in the second direction (e.g. a crank slider mechanism), so that the pull rod 142 will move in the second direction under the rotation of the movable rod 141, so as to drive the locking member 130 to move, so that the elastic member 120 lifts the upper plate body 111, thereby realizing the fixation of the transfer trolley by the upper plate body 111.

[0046] In some embodiments, with reference to Figure 1 , Figure 2 and Figure 5As shown, the upper plate body 111 includes opposite first end 1111 and second end 1112, wherein the first end 1111 is the position where the upper plate body 111 is rotatably connected to the lower plate body 112, in this embodiment, the first end 1111 is the end position of the upper plate body 111, in other embodiments, the first end 1111 can also be a position between the two ends of the upper plate body 111. The first end 1111 is rotatably connected to the lower plate body 112 so that the upper plate body 111 can rotate relative to the lower plate body 112, and the elastic member is arranged between the first end 1111 and the second end 1112 in the second direction, so that the elastic member 120 can lift the second end 1112 in the first direction. The side of the movable rod 141 away from the lower plate body 112 extends in the first direction to form a first limiting portion 1411, that is, the lower plate body 112 is arranged below the movable rod 141, one end of the movable rod 141 is connected to the lower plate body 112, and the other end extends upward to form the first limiting portion 1411. The first limiting portion 1411 is arranged between the first end 1111 and the elastic member 120, and the first limiting portion 1411 will move with the movable rod 141, thereby adjusting the height of the top of the first limiting portion 1411 relative to the tail plate, so that the first limiting portion 1411 can be adapted to the transfer trolley with different height chassis.

[0047] Specifically, in this embodiment, the elastic member 120 is arranged on the side close to the second end 1112, that is, the distance between the elastic member 120 and the second end 1112 is less than the distance between the elastic member 120 and the first end 1111, thereby making the elastic member 120 lift the second end 1112 of the upper plate body 111, so that the second end 1112 of the upper plate body 111 always abuts against the transfer trolley to limit the transfer trolley from falling off from the second end 1112. In the first direction, the side of the first limiting portion 1411 away from the lower plate body 112 is farther away from the lower plate body 112 than the side of the upper plate body 111 away from the lower plate body 112 corresponding to the position of the first limiting portion 1411. That is: after the movable rod 141 is connected to the lower plate body 112, due to the connection of the upper plate body 111 to the lower plate body 112, the upper plate body 111 and the first limiting portion 1411 will have a part of the position corresponding, refer to Figure 5As shown, the upper plate body 111 will have a part to shield the movable rod 141, and this part is the part corresponding to the position of the first limiting part 1411. In the vertical direction, the distance from the side of the part of the upper plate body 111 corresponding to the position of the first limiting part 1411 to the lower plate body 112 is less than the distance from the side of the first limiting part 1411 to the lower plate body 112, wherein the embodiment does not limit the specific position of the upper plate body 111 and the first limiting part 1411 to the lower plate body 112, as long as the position of the part of the upper plate body 111 corresponding to the position of the first limiting part 1411 to the lower plate body 112 is the same as the position of the first limiting part 1411 to the lower plate body 112. Thus, the first limiting part 1411 can limit the transfer trolley.

[0048] Therefore, the first limiting part 1411 is arranged between the first end 1111 and the elastic member 120, so that the anti-slip mechanism 100 can limit the transfer trolley at both ends of the upper plate body 111, thereby improving the strength of the anti-slip mechanism 100 to fix the transfer trolley, further limiting the sliding of the transfer trolley, and reducing the risk of the transfer trolley falling.

[0049] In some embodiments, referring to Figure 2 and Figure 3 As shown, the upper plate body 111 includes an abutting part 1113, and the side of the upper plate body 111 facing the locking member 130 extends along the second direction to form the abutting part 1113. The abutting part 1113 is used to connect with the locking member 130. Specifically, when the upper plate body 111 is in the first position, the abutting part 1113 is arranged below the locking member 130 along the first direction, and the locking member 130 abuts against the abutting part 1113, so that the locking member 130 and the upper plate body 111 jointly compress the elastic member 120, and at the same time, due to the abutment of the locking member 130 against the abutting part 1113, the upper plate body 111 cannot be lifted along the first direction even under the elastic force of the elastic member 120, so that the transfer trolley can normally pass through the anti-slip mechanism 100. When the locking member 130 moves along the second direction to separate from the abutting part 1113, the locking member 130 no longer limits the upper plate body 111, so that the upper plate body 111 can be lifted to abut against the transfer trolley.

[0050] Further, in some embodiments, referring to Figures 2 to 4As shown, the locking member 130 comprises a locking body 131 and a locking portion 132. The locking body 131 is connected to the lower plate body 112, and the locking body 131 has a receiving cavity 1311 defined inside. The locking portion 132 is arranged in the receiving cavity 1311. The locking portion 132 is used to abut against the abutment portion 1113 of the upper plate body 111. Specifically, the locking portion 132 is connected to the movable assembly 140, and the locking portion 132 is movably arranged in the receiving cavity 1311. When the movable assembly 140 moves relative to the lower plate body 112, the movable assembly 140 drives the locking portion 132 to move in the second direction in the receiving cavity 1311, so that the locking portion 132 and the abutment portion 1113 are separated, and the elastic member 120 lifts the upper plate body 111. In this embodiment, the side of the locking portion 132 facing the movable assembly 140 is provided with a pull ring, and the movable assembly 140 is connected to the pull ring. When the movable assembly 140 moves, the movable assembly 140 pulls the pull ring in the second direction, so that the locking portion 132 moves relative to the abutment portion 1113 in the second direction. In other embodiments, the movable assembly 140 can also be directly connected to the locking portion 132.

[0051] Meanwhile, the locking portion 132 has a slope structure. When the upper plate body 111 is in the first position, one side of the locking portion 132 is connected to the abutment portion 1113 of the upper plate body 111, and the slope structure is arranged opposite to the side of the locking portion 132 connected to the abutment portion 1113 in the first direction, i.e. the slope structure is arranged above the side of the locking portion 132 connected to the abutment portion 1113. Through the slope structure, when the upper plate body 111 is stored, after the upper plate body 111 contacts the slope structure, the locking portion 132 will automatically move in the second direction to make the upper plate body 111 in the first position, without the need to pull the locking portion 132 again, thereby improving the storage convenience of the upper plate body 111.

[0052] In some embodiments, referring to Figure 1 , Figure 2 and Figure 5 , the upper plate body 111 has a first end 1111 and a second end 1112 arranged opposite in the second direction. In this embodiment, the first end 1111 and the second end 1112 are two ends of the upper plate body 111 in the second direction. The first end 1111 is rotatably connected to the lower plate body 112, and the connection between the first end 1111 and the lower plate body 112 has a rotation axis. The first end 1111 of the upper plate body 111 can rotate relative to the lower plate body 112 about the rotation axis. The elastic member 120 is arranged on the side close to the second end 1112, i.e. in the second direction. The elastic member 120 is between the first end 1111 and the second end 1112, and the distance between the first end 1111 and the elastic member 120 is greater than the distance between the second end 1112 and the elastic member 120. The elastic member 120 is used to lift the second end 1112 in the first direction, so that the second end 1112 can abut against the bottom of the transfer trolley.

[0053] Meanwhile, referring to Figure 5 and Figure 6 , the upper plate body 111 further comprises a second limiting portion 1114 connected to the second end 1112. In the vertical direction, the distance between the side of the second limiting portion 1114 away from the lower plate body 112 is greater than the distance between the side of the second end 1112 away from the lower plate body 112. Specifically, one end of the second limiting portion 1114 is connected to the second end 1112 of the upper plate body 111, and the other end extends in the first direction, so that after the upper plate body 111 abuts against the bottom of the transfer trolley, the second limiting portion 1114 can limit the movement of the transfer trolley in the second direction. In this embodiment, the specific position of the second limiting portion 1114 and the second end 1112 to the lower plate body 112 is not limited, as long as the position of the side of the second limiting portion 1114 away from the lower plate body 112 and the side of the second end 1112 away from the lower plate body 112 is the same.

[0054] In some embodiments, referring to Figure 1 and Figure 5 , the anti-slip mechanism 100 further comprises a pedal 150 arranged at the second end 1112 of the upper plate body 111, and the pedal 150 is connected to the side of the second limiting portion 1114 away from the first end 1111 in the second direction. Specifically, the pedal 150 is used for the user to step on to achieve the compression of the elastic member 120 by the upper plate body 111. When the tail plate is lifted to the specified position and needs to be disassembled from the transfer trolley, the pedal 150 can make the upper plate body 111 rotate relative to the lower plate body 112, so that the second end 1112 compresses the elastic member 120 to store the upper plate body 111, so that the upper plate body 111 no longer limits the transfer trolley. The pedal 150 can improve the storage of the upper plate body 111 and improve the efficiency of disassembling the transfer trolley. Moreover, since the second limiting portion 1114 is used for abutting and limiting the transfer trolley, the pedal 150 is connected to the side of the second limiting portion 1114 away from the first end 1111, which can improve the overall strength of the second limiting portion 1114, so that the second limiting portion 1114 and the pedal 150 can jointly limit the transfer trolley to improve the stability of the fixed transfer trolley.

[0055] In some embodiments, referring to Figure 2 and Figure 5As shown, the anti-skid mechanism 100 further comprises a fixing member 160 connected to the lower plate body 112. In this embodiment, the fixing member 160 is arranged at the end of the lower plate body 112 along the second direction. Specifically, the fixing member 160 is used to connect the tail plate so that the anti-skid mechanism 100 is fixed on the tail plate. The anti-skid mechanism 100 is hooked on the end of the tail plate along the second direction through the fixing member 160. By arranging the fixing member 160 at the end of the lower plate body 112, when the tail plate is inclined relative to the ground, the anti-skid mechanism 100 can be prevented from moving relative to the tail plate through the fixing member 160, thereby improving the connection strength of the anti-skid mechanism 100 and the tail plate. In other embodiments, the fixing member 160 can also be connected to the side wall (front-rear direction) of the lower plate body 112, or connected to the bottom of the lower plate body 112 along the first direction, i.e. the fixing member 160 is arranged between the lower plate body 112 and the tail plate.

[0056] The tail plate device 10 of the second aspect of the present application will be described below with reference to the accompanying drawings of the specification. Referring to Figure 6 As shown, the tail plate device 10 comprises a tail plate 200 and the anti-skid mechanism 100 described in any of the above embodiments. Among them, the tail plate 200 is used to support the transfer trolley 300. The lower plate body 112 of the anti-skid mechanism 100 is connected to the tail plate 200, and the upper plate body 111 is used to switch between the first position and the second position, so that the transfer trolley 300 can be fixed to the tail plate 200 or detached from the tail plate 200.

[0057] Specifically, referring to Figures 1 to 6 As shown, when the transfer trolley 300 is loaded on the tail plate 200, the upper plate body 111 is in the first position, so that the transfer trolley 300 can pass from above the upper plate body 111. After the transfer trolley 300 is stabilized on the tail plate 200, at this time the anti-skid mechanism 100 is arranged below the transfer trolley 300, by pulling the movable assembly 140 to drive the locking member 130 to move along the second direction, the locking member 130 and the upper plate body 111 are separated, so that the upper plate body 111 is lifted by the elastic member 120 to abut against the bottom of the transfer trolley 300, thereby limiting the transfer trolley 300 and fixing the transfer trolley 300 on the tail plate 200. When the tail plate 200 is lifted, the transfer trolley 300 can be prevented from sliding relative to the tail plate 200 and falling off the tail plate 200 through the anti-skid mechanism 100. When the tail plate 200 reaches the designated position, the upper plate body 111 compresses the elastic member 120, and the locking member 130 abuts against the upper plate body 111, thereby allowing the transfer trolley 300 to slide again for loading or detaching.

[0058] The tail plate device 10 of the embodiment of the utility model switches the upper plate body 111 between the first position and the second position through control, so that the transfer trolley 300 can be fixed or detached from the tail plate 200. Moreover, switching the upper plate body 111 from the first position to the second position makes the anti-skid mechanism 100 fix the transfer trolley 300 on the tail plate 200 when the transfer trolley 300 is loaded on the vehicle body through the lifting of the tail plate 200, avoiding the transfer trolley 300 from sliding on the tail plate 200 and falling, and improving the safety of the tail plate device 10.

[0059] The above has made detailed description to the embodiment of the utility model in combination with the drawings, but the utility model is not limited to the above-mentioned embodiment, still can make various changes in the knowledge range possessed by the ordinary skill in the art without departing from the purpose of the utility model. Besides, the embodiment and the features in the embodiment of the utility model can be combined mutually without conflict.
