Description

Technical Field

[0001] This utility model relates to the field of shifting material rack technology, and specifically to a telescopic shifting material rack. Background Technology

[0002] In factories, warehouses and other places, there is often a need to move goods. Workers usually place the goods on moving racks and work with forklifts to complete the moving operation.

[0003] To facilitate loading and unloading, traditional moving racks generally lack barriers on their loading surfaces. When a forklift suddenly moves or stops on the road, some goods with low friction with the moving rack may be moved away from their original positions on the moving rack due to inertia, increasing the risk of collision damage between goods and the risk of goods falling off the moving rack. Utility Model Content

[0004] The purpose of this utility model is to provide a telescopic shifting rack, which has the advantages of safe storage of goods, convenient use, and flexible adjustment.

[0005] The technical solution of this utility model is as follows:

[0006] A telescopic shifting rack includes a rectangular frame. Each of the left and right side plates of the frame has a pair of forks for engaging with forklift forks. Several support frames are evenly distributed between the front and rear side plates of the frame along the left-right direction. There are mounting gaps along the front-back direction between the left and right side plates of the frame and the support frames, and between adjacent support frames. Several stop bars, each covered with a rubber sleeve, are evenly rotatably connected along the length of each mounting gap. A rotating rod is provided on the side of each stop bar and rotatably connected to the inner wall of the mounting gap. A control component connected to the stop bar is provided on each mounting gap. The initial position of the stop bar is hidden within the mounting gap. The control component is used to rotate the stop bar to control whether it rotates out of the upper opening of the mounting gap.

[0007] Preferably, the control component includes a threaded rod, a threaded sleeve, a guide groove, and a throttle. The threaded rod is rotatably connected in the front-to-back direction within the mounting gap. The beginning and end ends of the threaded rod are rotatably connected to the beginning and end ends of the mounting gap, respectively. The rear end of the threaded rod extends out of the frame, and a throttle is provided on the extended portion. Several threaded sleeves corresponding one-to-one with the stop bar are threadedly connected to the threaded rod. The top of the threaded sleeve is provided with a guide groove, and the side of the stop bar is provided with a guide block. The guide block slides along the guide groove. The plane of the guide groove is perpendicular to the left-to-right direction, and there is an angle between the direction of the guide groove and the front-to-back direction.

[0008] Preferably, the guide block is located at the bottom of the side of the stop rod, and the rotating rod is closer to the middle of the stop rod than the guide block. The guide groove includes an upper downward sloping portion, a lower horizontal portion, and an arc-shaped portion connecting the two. When the guide block is located at the top of the lower sloping portion of the guide groove, the stop rod is in the horizontal direction and hidden in the installation gap. When the guide block is located in the horizontal portion of the guide groove, the stop rod is in the vertical direction and extends out of the installation gap.

[0009] Preferably, when the stop bar is in the horizontal direction, the upper surface of the stop bar is flush with the upper opening of the mounting hole, and a limiting block is provided in the mounting hole, the limiting block abutting against the lower surface of the stop bar.

[0010] Preferably, the left and right sides of the stop bar are each provided with a guide block, and the two guide blocks connected to the same stop bar are symmetrical about the stop bar. The top of the threaded sleeve is provided with a pair of guide grooves that are symmetrical about the threaded sleeve, and the guide blocks can slide in the corresponding guide grooves.

[0011] Preferably, the outer wall of the threaded sleeve is provided with a pair of symmetrical sliders, and the inner wall of the mounting gap is provided with a sliding groove along the front-back direction, and the sliders and the sliding groove are slidably connected.

[0012] Preferably, a fastening nut is threaded onto the portion of the threaded rod that extends beyond the frame at its rear end, and the fastening nut can be screwed inward to abut against the frame wall.

[0013] Preferably, the top of the front and rear side plates of the frame is provided with baffles corresponding to the support frame positions.

[0014] Preferably, the front and rear side panels of the frame are each provided with a pair of forks.

[0015] Preferably, the top of the frame has a vertical support post at each of the four corners, the top of the support post has a groove, and the bottom of the frame has a protrusion at each of the four corners, the protrusion corresponding to the groove.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] A stop bar extending from the opening above the mounting gap separates goods placed on different support frames. The stop bar can also be positioned between the goods and the left and right side panels of the frame, thereby reducing the risk of goods colliding and falling off the support frames due to sudden forklift movements and stops. Workers can operate the stop bar by rotating it upwards to release the mounting gap or downwards to retract it into the mounting gap. This allows for both the release and retraction of the stop bar as needed when loading and unloading goods, and the selection of the release position based on the size and placement of the goods. It is convenient to use and flexible to adjust. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] Example:

[0029] like Figures 1 to 7 As shown, this embodiment provides a telescopic shifting rack, including a rectangular frame 1. Each of the left and right side plates of the frame 1 is provided with a pair of forks 17 for docking with forklift forks. Several support frames 2 are evenly arranged between the front and rear side plates of the frame 1 in the left-right direction. There are installation gaps 3 between the left and right side plates of the frame 1 and the support frames 2, and between adjacent support frames 2 in the front-back direction. Several stop rods 4 with rubber sleeves are evenly rotatably connected to the installation gaps 3 along the length direction. The side of the stop rod 4 is provided with a rotating rod 5 that is rotatably connected to the inner wall of the installation gap 3. The installation gap 3 is provided with a control component 6 connected to the stop rod 4. The initial position of the stop rod 4 is hidden inside the installation gap 3. The control component 6 is used to rotate the stop rod 4 to control whether the stop rod 4 rotates out of the upper opening of the installation gap 3.

[0030] Goods placed on different support frames 2 are separated by a stop bar 4 extending from the opening above the mounting gap 3. The stop bar 4 can also block the goods between the goods and the left and right side panels of the frame 1, thereby reducing the risk of goods colliding and being damaged by sudden forklift movements and stops, and the risk of goods falling off the support frames 2. The operator can operate the stop bar 4 to rotate upward to release the mounting gap 3 or to rotate downward to retract it into the mounting gap 3 through the control component 6. First, the stop bar 4 can be retracted as needed when picking up or putting down goods. Second, the position where the stop bar 4 needs to be released can be selected according to the size of the goods and the placement of the goods. It is convenient to use and flexible to adjust.

[0031] In practical use, staff need to assess the suitability of the goods based on their actual condition. Selecting suitable goods makes it easier to achieve the desired anti-collision and anti-fall effects. Due to limitations in the gap size and protrusion height of adjacent baffles 4 within the same installation gap 3, there are certain requirements for the size of the goods and the height of their center of gravity. If the size of the goods is smaller than the gap between adjacent baffles 4, the risk of the baffles 4 passing through the gap is high. If the center of gravity of the goods is too high, the risk of the goods tipping over the baffles 4 is high. In addition, the lack of baffles 4 between goods placed together on the same or multiple support frames 2 can generally reduce the risk of collision damage by reducing the number of such goods and the spacing between them.

[0032] Specifically, in this utility model, the number of installation gaps is 3, the number of stop bars 4 in the same installation gap 3 is 6, and the support frame 2 is composed of a pair of longitudinal bars along the front-back direction and several cross bars evenly arranged between the two longitudinal bars.

[0033] Furthermore, the control component 6 includes a threaded rod 7, a threaded sleeve 8, a guide groove 9, and a throttle 10. The threaded rod 7 is rotatably connected in the front-to-back direction within the mounting neutral 3. The beginning and end ends of the threaded rod 7 are rotatably connected to the beginning and end ends of the mounting neutral 3, respectively. The rear end of the threaded rod 7 extends out of the frame 1, and a throttle 10 is provided on the extended part. Several threaded sleeves 8, corresponding one-to-one with the stop rod 4, are threadedly connected to the threaded rod 7. The top of the threaded sleeve 8 is provided with a guide groove 9, and the side of the stop rod 4 is provided with a guide block 11. The guide block 11 slides along the guide groove 9. The plane where the guide groove 9 is located is perpendicular to the left-to-right direction, and there is an angle between the direction of the guide groove 9 and the front-to-back direction.

[0034] The operator rotates the threaded rod 7 by turning the handle 10. The rotating threaded rod 7 drives the threaded sleeve 8, which is threaded to it, to move along the axis of the threaded rod 7. The guide groove 9, connected to the threaded sleeve 8, moves accordingly in the front-back direction. There is an angle between the direction of the guide groove 9 and the front-back direction. The guide block 11 slides relative to the guide groove 9. The change in height of the guide block 11 causes the stop rod 4 to rotate, thus controlling the retraction and extension of the stop rod 4 from the installation gap 3. The threaded connection structure between the threaded sleeve 8 and the threaded rod 7 has a certain self-locking capability, reducing the risk of the stop rod 4 loosening and preventing it from affecting use due to accidental retraction. The stop rods 4, which are in the same installation gap 3, are operated by the same handle 10, improving the efficiency of the retraction and extension of the stop rod 4.

[0035] Furthermore, the guide block 11 is located at the bottom of the side of the stop rod 4, and the rotating rod 5 is closer to the middle of the stop rod 4 than the guide block 11. The guide groove 9 includes an upper downward sloping portion, a lower horizontal portion, and an arc-shaped portion connecting the two. When the guide block 11 is located at the top of the lower sloping portion of the guide groove 9, the stop rod 4 is in the horizontal direction and is hidden in the mounting gap 3. When the guide block 11 is located in the horizontal portion of the guide groove 9, the stop rod 4 is in the vertical direction and extends out of the mounting gap 3.

[0036] When the threaded sleeve 8 moves away from the rotating rod 5 driven by the threaded rod 7, the guide block 11 moves in the guide groove 9 in a direction that tends to decrease in height. The stop rod 4, driven by the descending guide block 11, rotates upward. After the guide block 11 moves from the downward-sloping part to the horizontal part through the arc section, the stop rod 4 turns to the vertical direction. When the threaded sleeve 8 moves closer to the rotating rod 5 driven by the threaded rod 7, the stop rod 4, driven by the rising guide block 11, rotates downward. When the guide block 11 moves back to the top of the downward-sloping part of the guide groove 9, the stop rod 4 turns back to the horizontal direction.

[0037] Furthermore, when the stop lever 4 is in the horizontal direction, the upper surface of the stop lever 4 is flush with the upper opening of the mounting neutral 3, and the mounting neutral 3 is provided with a limiting block 12, which abuts against the lower surface of the stop lever 4.

[0038] When the stop lever 4 is in the retracted state, it can distribute the pressure on the goods without affecting the flatness of the goods. The limit block 12 is used to prevent the stop lever 4 from rotating too low and to distribute the pressure on the stop lever 4.

[0039] Furthermore, guide blocks 11 are provided on the left and right sides of the stop bar 4. The two guide blocks 11 connected to the same stop bar 4 are symmetrical about the stop bar 4. A pair of guide grooves 9 are provided on the top of the threaded sleeve 8, which are symmetrical about the threaded sleeve 8. The guide blocks 11 can slide in the corresponding guide grooves 9.

[0040] The combination of two sets of symmetrical guide blocks 11 and guide grooves 9 makes the rotation of the stop lever 4 smoother.

[0041] Furthermore, the outer wall of the threaded sleeve 8 is provided with a pair of symmetrical sliders 13, and the inner wall of the mounting gap 3 is provided with a sliding groove 14 along the front-back direction, and the sliders 13 and the sliding groove 14 are slidably connected.

[0042] By using the combination of the groove 14 and the slider 13, the movement trajectory of the threaded sleeve 8 is restricted, making the movement of the threaded sleeve 8 in the front-back direction smoother.

[0043] Furthermore, a fastening nut 15 is threaded onto the portion of the threaded rod 7 that extends out of the frame 1 at its rear end. The fastening nut 15 can be screwed inward to abut against the wall of the frame 1.

[0044] The friction between the fastening nut 15 and the wall of the frame 1 restricts the rotation ability of the threaded rod 7, further improving the fixing effect on the retractable state of the stop rod 4.

[0045] Furthermore, the top of the front and rear side plates of the frame 1 is provided with baffles 16 corresponding to the positions of the support frame 2.

[0046] By blocking the loading and unloading passage in the front and rear directions with baffle 16, the risk of goods falling in the front and rear directions is reduced.

[0047] Furthermore, a pair of forks 17 are provided on the front and rear side plates of the frame 1.

[0048] The frame 1 has fork openings 17 in all four directions (front, back, left, and right) to facilitate docking of the forklift with the frame 1 and make it more convenient to use. When the forklift fork arm docks with the fork opening 17 in the front and back directions, the baffle 16 mainly prevents the goods from sliding due to the sudden movement and stopping of the forklift. Specifically, in this embodiment, there are also reinforcing rods between the front and back side plates and between the left and right side plates of the frame 1. The reinforcing rods are provided with fork arm grooves that are connected to the fork openings 17 and in the same direction.

[0049] Furthermore, the top of the frame 1 is provided with a vertical support post 18 at each of the four corners, and the top of the support post 18 is provided with a groove 19. The bottom of the frame 1 is provided with a protrusion 20 at each of the four corners, and the protrusion 20 corresponds to the groove 19.

[0050] The top of the support column 18 abuts against the bottom of the frame 1, leaving space between adjacent frames 1 for placing goods, making it convenient for the frames 1 to be stacked. The groove 19 and the protrusion 20 are used together to reduce the risk of the frames 1 sliding and misaligning on the top of the support column 18, and improve the stability of the stacked frames 1.

[0051] Working principle and usage process of this utility model:

[0052] The staff first places the goods on the support frame 2 in the loading and unloading passage in the left and right directions. Then, according to the placement position and size of the goods, they selectively rotate the baffles 4 between the support frames 2. Next, they rotate the baffles 4 located on the leftmost and rightmost sides. Then, they tighten the fastening nut 15 to abut against the frame 1 to restrict the rotation of the threaded rod 7. Finally, they operate the fork arm to insert into the fork 17 in the appropriate direction and drive the fork with the frame 1 to the transport destination.

[0053] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
