Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a folding telescopic support platform. Background Technology

[0002] Workbenches possess excellent corrosion resistance, dirt resistance, impact resistance, and strong load-bearing capacity, making them suitable for various applications such as assembling and processing mechanical parts. They are frequently used in mechanical manufacturing enterprises for fixing or lifting products. Depending on their purpose, workbenches can be divided into fixed and lifting types. Lifting workbenches are multi-functional lifting and unloading machinery. After being lifted, these workbenches rely on hydraulic cylinders, motors, or the equipment's own self-locking function to achieve suspension. However, when encountering heavy products or equipment, or situations requiring support, insufficient support often leads to instability. The self-locking function severely impacts work efficiency.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0026] Example

[0027] In one embodiment of the present invention, reference is made to... Figure 1 and 2 As shown, a foldable telescopic support platform of the present invention includes a flat base 1 with a first abutment seat 17. The first abutment seat 17 is configured as four cylinders of the same height, which are distributed on the base 1 in a rectangular arrangement.

[0028] The support platform 3 is used to place parts and other products. Its bottom is provided with a second abutment 16 corresponding to the first abutment 17. The second abutment 16 is set as four cylinders of the same height. The four cylinders are distributed on the base 1 in a rectangular arrangement. The support platform 3 is arranged parallel to the base 1.

[0029] The driver 2 is connected to the base 1 and is used to drive the support platform 3 to move up and down. It is preferably configured as a cylinder.

[0030] The lifting assembly 5 includes a crossbar 7 and an upper support rod 10 and a lower support rod 12 movably connected to the crossbar 7 via the same hinge seat 6. The crossbar 7 is arranged parallel to the base 1. The other end of the upper support rod 10 is movably connected to the base 1, and the other end of the lower support rod 12 is movably connected to the support platform 3. The power output end of the driver 2 is connected to the crossbar 7 and drives the crossbar 7 to move along its axial direction. The crossbar 7 is provided with a support plate 18, which moves with the crossbar 7 and abuts against the support platform 3 between the first abutment seat 17 and the second abutment seat 16.

[0031] During the movement of the crossbar 7 in the positive X direction along its axial direction, when the support plate 18, the first abutment seat 17 and the second abutment seat 16 are on the same straight line, the support plate 18 abuts against the first abutment seat 17 and the second abutment seat 16 to support the support platform 3. During the movement of the crossbar 7 in the negative X direction along its axial direction, the support plate 18 moves away from the first abutment seat 17 and the second abutment seat 16.

[0032] In one embodiment of the present invention, reference is made to... Figure 1 As shown, the housing of the driver 2 is movably connected to the base 1, and the power output end is movably connected to the crossbar 7. Since the horizontal height of the crossbar 7 changes constantly as it moves along its axial direction under the drive of the driver 2, the position of the power output end is also adjusted accordingly.

[0033] In one embodiment of the present invention, reference is made to... Figure 1As shown, it also includes a guide assembly, which includes a guide seat 14 disposed on the base 1 and a guide rod 15 disposed on the support platform 3. The guide seat 14 is provided with a guide hole 4, and the guide rod 15 passes through the guide hole 4. The moving direction of the guide rod 15 is consistent with the moving direction of the support platform 3. The function of the guide assembly is to ensure that the support platform 3 can only rise or fall in the vertical direction.

[0034] In one embodiment of the present invention, reference is made to... Figure 1 As shown, it includes two guide components, which are respectively disposed on both sides of the crossbar 7 to further enhance the limiting effect.

[0035] In one embodiment of the present invention, reference is made to... Figure 2 As shown, the total length of the guide rod 15 and the guide hole 4 is greater than the total length of the upper support rod 10 and the lower support rod 12. The purpose is to ensure that when the support platform 3 is at the highest horizontal plane, the guide rod 15 is still set inside the guide hole 4, preventing the guide rod 15 from falling out of the guide hole 4.

[0036] In one embodiment of the present invention, reference is made to... Figure 2 As shown, the lifting assembly 5 includes a first lifting assembly 11 and a second lifting assembly 13. The guide assembly is disposed between the first lifting assembly 11 and the second lifting assembly 13. The first lifting assembly 11 and the second lifting assembly 13 are respectively disposed on both sides of the support platform 3, with the purpose of maintaining the stability of the support platform 3 and enhancing the supporting force of the support platform 3.

[0037] In one embodiment of the present invention, reference is made to... Figure 1 As shown, the support platform 3 includes two support plates 18, which are respectively disposed in the first lifting assembly 11 and the second lifting assembly 13. At least one support plate 18 is disposed between the first lifting assembly 11 and the second lifting assembly 13 to improve the stability of the support platform 3 and prevent the support platform 3 from tipping over.

[0038] In one embodiment of the present invention, reference is made to... Figure 1 As shown, it also includes a buffer assembly disposed on the base 1. The buffer assembly is disposed on the end of the crossbar 7 opposite to the end connected to the power output end, and the crossbar 7 is aligned with the buffer assembly. During the lifting process of the support platform 3, when the crossbar 7 moves into place, one end of it presses against the buffer assembly to slow down the speed.

[0039] In one embodiment of the present invention, reference is made to... Figure 1As shown, the buffer assembly includes a mounting base 8 disposed on the base 1 and a buffer head 9 connected to the mounting base 8 via an adjustment assembly. The buffer head 9 is aligned with the crossbar 7 and can be extended axially via the adjustment assembly.

[0040] In one embodiment of the present invention, reference is made to... Figure 2 As shown, both the upper support rod 10 and the lower support rod 12 include a first support rod and a second support rod. The first support rod and the second support rod are respectively arranged on both sides of the crossbar 7. Specifically, the first support rod and the second support rod of the upper support rod 10 are arranged inside the first support rod and the second support rod of the lower support rod 12.

[0041] In one embodiment of the present invention, reference is made to Figure 1 As shown, the lower support rod 12, the upper support rod 10 and the cross rod 7 are connected by a hinge 6.

[0042] In one embodiment of the present invention, reference is made to Figure 1 As shown, the base 1 is hinged to the lower support rod 12.

[0043] In one embodiment of the present invention, reference is made to Figure 1 As shown, the upper support rod 10 is hinged to the support platform 3.

[0044] In one embodiment of the present invention, reference is made to Figure 1 As shown, the end of the crossbar 7 connected to the driver 2 is provided with a hinge 6, and the power output end is connected to the hinge 6.

[0045] The working principle of the foldable telescopic support platform described in this invention is as follows:

[0046] The part is placed on the support platform 3. The driver 2 drives the crossbar 7 to move in the positive X direction. The upper support rod 10 and the lower support rod 12 open around the hinge 6. The upper support rod 10 supports the support platform 3 to rise. At the same time, the distance between the first abutment 17 and the second abutment 16 increases. The guide rod 15 rises. When the support plate 18, the cylinder of the first abutment 17 and the cylinder of the second abutment 16 are on the same vertical plane, the driver 2 stops driving. The support plate 18 abuts between the first abutment 17 and the second abutment 16 to firmly support the support platform 3. The driver 2 drives the crossbar 7 to move in the negative X direction. The support plate 18 moves away from the first abutment 17 and the second abutment 16. The upper support rod 10 and the lower support rod 12 fold around the hinge 6. The guide rod 15 descends and the support platform 3 descends.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
