Description

Technical Field

[0001] The utility model relates to the technical field of pallet racks, and more specifically, to a pallet rack for circulating electric forklift parts. Background Art

[0002] With the rapid development of electric forklifts, electric forklifts are often used for the circulation of parts. However, the existing electric forklift parts circulation pallet racks are prone to shaking when lifting, which leads to the goods being easily dumped and damaged during the lifting process of the pallet racks.

[0003] As retrieved from the existing related patent: CN215558778U, an electric forklift accessory circulation pallet rack is disclosed. The prior art squeezes the clamping guide plates on both sides during the process of inserting the forklift into the rectangular plug-in slot. The clamping guide plates are squeezed so that the extrusion blocks squeeze the force-bearing circular table. The force-bearing circular table is squeezed so that the transmission rod moves upward. The transmission rod moves upward so that the middle rod controls the extrusion rod to squeeze the transmission circular table. The transmission circular table is squeezed to control the fitting stabilizing plate to move downward to achieve the effect of fitting and fixing the forklift insertion structure, thereby achieving the effect of ensuring the stability of the pallet body during the lifting process.

[0004] However, the inventor discovered that the prior art has the following problems: when the fork is inserted into the rectangular plug-in slot and squeezes the two clamping guide plates, since the existing forks have the same width and are not smaller in the front and larger in the back, when the fork squeezes the two clamping guide plates, the fitting stabilizing plate directly contacts the top surface of the fork. At this time, when the fork is inserted into the rectangular plug-in slot, the fitting stabilizing plate will affect the fork, causing the fork to get stuck or even stuck when inserted. At the same time, when the existing fork is transporting the pallet rack, the fork will squeeze the top wall of the rectangular plug-in slot, thereby squeezing the fitting stabilizing plate. Therefore, the inventor believes that the fitting stabilizing plate cannot effectively stabilize the fork. In response to this problem, the inventor has designed a new electric forklift parts circulation pallet rack. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an electric forklift parts circulation pallet rack in which, when the fork is not fully inserted into the fork slot, the top plate will not affect the insertion of the fork, further ensuring the smoothness of the fork insertion into the pallet rack, and facilitating the use of the pallet rack.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pallet rack for circulating accessories for electric forklifts comprises a pallet body, wherein two fork slots are provided on the pallet body, a rotating shaft is fixedly connected between inner walls on opposite sides of the fork slots, the rotating shaft is arranged on a side away from an entrance of the fork slots, a rear contact plate is rotatably sleeved on the rotating shaft, an extrusion rod is arranged on the lower side of the rear contact plate, an inner cavity is provided in the pallet body, the inner cavity is located below the fork slots, the lower end of the extrusion rod slides through the inner cavity, a pushing plate is arranged on the bottom wall of the inner cavity, a second rotating plate is hinged between the lower end of the extrusion rod and the pushing plate, a first rotating plate is hinged on the other side of the pushing plate, a lifting rod is rotatably connected to the first rotating plate, the upper end of the lifting rod slides through the fork slots, and the upper end of the lifting rod is fixedly connected to the top plate.

[0008] The utility model is further configured as follows: a limiting plate is fixedly sleeved on the outer surface of the lifting rod, a spring is fixedly connected between the upper surface of the limiting plate and the top wall of the inner cavity, and the spring is movably sleeved on the outer surface of the lifting rod.

[0009] The utility model is further configured as follows: two support plates are fixedly connected to the top wall of the inner cavity, the two support plates are horizontally arranged, a connecting slide rod is fixedly connected between the two support plates, and two connecting slide plates are slidably sleeved on the outer surface of the connecting slide rod.

[0010] The utility model is further configured as follows: the lower sides of the two connecting slide plates are fixedly connected to the upper side of the pushing plate.

[0011] The utility model is further configured as follows: a limiting slide groove is opened on the lower surface of the rear contact plate, a limiting slide ball is fixedly connected to the upper end of the extrusion rod, the limiting slide ball extends into the limiting slide groove and slides in the limiting slide groove.

[0012] The utility model is further configured as follows: the cross section of the limiting sliding groove is in an arc shape.

[0013] The advantages of the utility model are:

[0014] The utility model discloses that when the fork is fully inserted into the fork slot, the inclination angle of the rear contact plate is the largest, so that the lifting rod pushes the top plate upward to contact the lower surface of the fork, thereby achieving the effect of restricting the fork, avoiding the problem of shaking of the pallet rack when the fork is transporting the pallet rack as much as possible, and ensuring the stability of the use of the pallet rack. At the same time, the trigger structure is arranged at the rear section of the fork slot, so when the fork is not fully inserted into the fork slot, the top plate will not affect the insertion of the fork, further ensuring the smoothness of the fork insertion into the pallet rack, and facilitating the use of the pallet rack.

DETAILED DESCRIPTION

[0019] See also Figure 1-3 , the utility model provides the following technical solutions:

[0020] Specifically, it refers to an electric forklift parts circulation pallet rack, including a pallet body 1, on which two fork slots 2 are provided. Therefore, when in use, two forks of the electric forklift are inserted into the two fork slots 2, so that the pallet can be transported.

[0021] Specifically, a rotating shaft 3 is fixedly connected between the inner walls on both sides of the opposite sides of the fork slot 2, and the rotating shaft 3 is arranged on the side away from the entrance of the fork slot 2. A rear contact plate 4 is rotatably sleeved on the rotating shaft 3, and an extrusion rod 15 is arranged on the lower side of the rear contact plate 4 for supporting the rear contact plate 4 so that the rear contact plate 4 is initially inclined. An inner cavity 11 is opened in the pallet body 1, and the inner cavity 11 is located below the fork slot 2. The lower end of the extrusion rod 15 slides through the inner cavity 11, and a pushing plate 9 is arranged on the bottom wall of the inner cavity 11. A second rotating plate 16 is hinged between the lower end of the extrusion rod 15 and the pushing plate 9, and a first rotating plate 10 is hinged on the other side of the pushing plate 9. A lifting rod 6 is rotatably connected to the first rotating plate 10, and the upper end of the lifting rod 6 slides through the fork slot 2, and the upper end of the lifting rod 6 is fixedly connected to the top plate 5;

[0022] When the forklift fork is inserted into the rear section of the fork slot 2, the fork contacts the rear contact plate 4. Since the bottom of most existing fork fork heads is generally an inclined surface, the inclined surface of the fork fork head will squeeze the rear contact plate 4, causing the rear contact plate 4 to rotate clockwise with the rotating shaft 3 as the rotation point, so that the rear contact plate 4 squeezes the squeezing rod 15, causing the squeezing rod 15 to move downward, and the second rotating plate 16 simultaneously forms a thrust on the pushing plate 9, causing the pushing plate 9 to move toward the side close to the lifting rod 6, so that the first rotating plate 10 forms an upward displacement on the lifting rod 6. When the fork is fully inserted into the fork slot 2, the rear contact plate 4 has a maximum inclination angle, so that the lifting rod 6 pushes the top plate 5 upward to contact the lower surface of the fork, thereby achieving the effect of restricting the fork, avoiding the problem of shaking of the pallet rack when the fork is transporting the pallet rack as much as possible, and ensuring the stability of the pallet rack in use. At the same time, the trigger structure is arranged at the rear section of the fork slot 2, so when the fork is not fully inserted into the fork slot 2, the top plate 5 will not affect the insertion of the fork, further ensuring the smoothness of the fork insertion into the pallet rack, and facilitating the use of the pallet rack.

[0023] Specifically, a limiting plate 7 is fixedly sleeved on the outer surface of the lifting rod 6, and a spring 8 is fixedly connected between the upper surface of the limiting plate 7 and the top wall of the inner cavity 11. The spring 8 is movably sleeved on the outer surface of the lifting rod 6. When the spring 8 is not squeezed, the spring 8 will generate a thrust on the limiting plate 7, so that the initial position of the top plate 5 is in contact with the bottom wall of the fork slot 2.

[0024] Specifically, two support plates 12 are fixedly connected to the top wall of the inner cavity 11, and the two support plates 12 are horizontally arranged. A connecting slide rod 13 is fixedly connected between the two support plates 12. Two connecting slide plates 14 are slidably sleeved on the outer surface of the connecting slide rod 13. The lower sides of the two connecting slide plates 14 are fixedly connected to the upper side of the push plate 9. Therefore, the connecting slide plates 14 and the connecting slide rods 13 form a support and restriction effect on the push plate 9, thereby avoiding the problem of deviation of the push plate 9 during displacement as much as possible.

[0025] Specifically, a limiting groove 18 is provided on the lower surface of the rear contact plate 4, and the cross-section of the limiting groove 18 is arc-shaped. A limiting sliding ball 17 is fixedly connected to the upper end of the extrusion rod 15. The limiting sliding ball 17 extends into the limiting groove 18 and slides in the limiting groove 18. Since the limiting groove 18 is arc-shaped, the limiting groove 18 can form a limiting effect on the limiting sliding ball 17, thereby avoiding the separation of the limiting sliding ball 17 from the rear contact plate 4 as much as possible. When the rear contact plate 4 squeezes the extrusion rod 15, the limiting sliding ball 17 slides in the limiting groove 18.

[0026] The working principle of the electric forklift parts circulation pallet rack provided by the utility model is as follows: when the forklift fork is inserted into the rear section of the fork slot 2, the fork contacts the rear contact plate 4. Since the bottom of the fork head position of most existing forks is generally an inclined surface, the inclined surface of the fork fork head will squeeze the rear contact plate 4, causing the rear contact plate 4 to rotate clockwise with the rotating shaft 3 as the rotation point, so that the rear contact plate 4 squeezes the squeezing rod 15, causing the squeezing rod 15 to move downward, and the second rotating plate 16 simultaneously forms a thrust on the push plate 9, causing the push plate 9 to move toward the side close to the lifting rod 6, so that the first rotating plate 10 forms an upward displacement of the lifting rod 6. When the fork is fully inserted into the fork slot 2, the inclination angle of the rear contact plate 4 is the largest, so that the lifting rod 6 pushes the top plate 5 upward to contact the lower surface of the fork, thereby achieving the effect of restricting the fork.
