Description

Technical Field

[0001] This utility model belongs to the field of jack technology, specifically relating to a highly stable jack. Background Technology

[0002] Jacks are a common type of lifting equipment, widely used in automotive repair, machinery installation and other scenarios. Their core requirement is to maintain stability during lifting and lowering to avoid safety accidents or equipment damage caused by structural swaying.

[0003] Existing jacks generally suffer from insufficient structural strength. Some products use only a single frame design for the base and top, which is prone to deformation under pressure. At the same time, during the lifting process driven by the drive module, the transmission components lack a stable guiding structure, which causes vibration during lifting, affecting not only the accuracy of use but also posing safety hazards. Utility Model Content

[0004] The main purpose of this utility model is to provide a highly stable jack, and to design a jack with a more stable structure and smoother lifting, so as to overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, this utility model provides a highly stable jack, comprising a support module and a drive module. The support module includes a base and a top seat, wherein: The base includes a base frame, a first side frame, a second side frame, a first slide rail, a second slide rail, a first mounting plate, and a second mounting plate. The first side frame and the second side frame are respectively installed on both sides of the base frame and both face the top seat. The first side frame is provided with a first vertical rod, a second vertical rod, and a first horizontal rod. The two ends of the first horizontal rod are respectively fixedly installed to the first side of the base frame through the first vertical rod and the second vertical rod. The second side frame is provided with a third vertical rod, a fourth vertical rod, and a second horizontal rod. The two ends of the second horizontal rod are respectively fixedly installed to the second side of the base frame through the third vertical rod and the fourth vertical rod. The first slide rail and the second slide rail are respectively fixedly installed to the base frame. The first mounting plate is fixedly installed between the first horizontal rod and the first side of the base frame, and the second mounting plate is fixedly installed between the second horizontal rod and the second side of the base frame. The top support includes a top frame, a third side frame, a fourth side frame, a third slide rail, a fourth slide rail, a third mounting plate, and a fourth mounting plate. The third side frame and the fourth side frame are respectively installed on both sides of the top frame and both face the base. The third side frame is provided with a fifth vertical rod, a sixth vertical rod, and a third horizontal rod. The two ends of the third horizontal rod are respectively fixedly installed to the first side of the top frame through the fifth vertical rod and the sixth vertical rod. The fourth side frame is provided with a seventh vertical rod, an eighth vertical rod, and a fourth horizontal rod. The two ends of the fourth horizontal rod are respectively fixedly installed to the second side of the top frame through the seventh vertical rod and the eighth vertical rod. The third slide rail and the fourth slide rail are respectively fixedly installed to the top frame. The third mounting plate is fixedly installed between the third horizontal rod and the first side of the top frame, and the fourth mounting plate is fixedly installed between the fourth horizontal rod and the second side of the top frame. The drive module includes a motor, a screw, a first-side scissor arm assembly, a second-side scissor arm assembly, a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod. The motor is fixedly mounted on the base frame. The first connecting rod has a first roller and a second roller at its two ends, respectively. The first roller is mounted on the first slide rail, and the second roller is mounted on the second slide rail. The screw passes through the first connecting rod and is threadedly connected to it. The second connecting rod is mounted between the first mounting plate and the second mounting plate. The third connecting rod has a third roller and a fourth roller at its two ends, respectively. The third roller is mounted on the third slide rail, and the fourth roller is mounted on the fourth slide rail. The fourth connecting rod is mounted between the third mounting plate and the fourth mounting plate. The bottom ends of the first-side scissor arm assembly and the second-side scissor arm assembly are both mounted between the first connecting rod and the second connecting rod, and the top ends of the first-side scissor arm assembly and the second-side scissor arm assembly are both mounted between the third connecting rod and the fourth connecting rod.

[0006] As a further preferred embodiment of the above technical solution, the first slide rail and the third slide rail are vertically aligned, and the second slide rail and the fourth slide rail are vertically aligned.

[0007] As a further preferred embodiment of the above technical solution, both the first slide rail and the second slide rail are mounted on the base frame by a plurality of first reinforcing rods.

[0008] As a further preferred embodiment of the above technical solution, both the third slide rail and the fourth slide rail are mounted on the top frame by a number of second reinforcing rods.

[0009] As a further preferred technical solution to the above technical solution, the bottom of the base frame is provided with several support pads.

[0010] The beneficial effects of this utility model are as follows: 1. High structural strength: Both the base and the top are connected to the mounting plate through side frames (multiple vertical bars + horizontal bars) to form a reinforced structure with multiple supports, which effectively improves the frame's resistance to deformation and avoids swaying caused by weak structure during use.

[0011] 2. Smoother lifting: In the drive module, the rollers of the connecting rod are all installed in a special slide rail. When the motor is driven by the screw, the rollers move in a direction along the slide rail. With the synchronous transmission of the scissor arm assembly, it ensures that there is no shaking during the lifting of the top seat, improving the accuracy and safety of use.

[0012] 3. Enhanced stability: The slide rail is fixed to the frame by reinforcing rods, and a support pad is added to the bottom of the base frame, which further enhances stability in terms of both "connection strength" and "ground contact", making it suitable for higher load application scenarios.
