Description

Technical Field

[0001] This utility model belongs to the field of jack technology, specifically a self-balancing jack with stable support. Background Technology

[0002] A jack is a common mechanical tool widely used in automotive repair, construction, and machinery maintenance to lift and raise heavy objects. Its basic principle is to utilize hydraulic, screw, or pneumatic forces to convert a small external force into a large lifting force, thereby raising the load. A typical jack consists of a base, lifting arm, hydraulic cylinder (for hydraulic jacks), piston, and handle. Its operation generally involves manually or electrically driving the piston or screw to gradually lift the load to the desired height.

[0003] Conventional jacks are mainly supported by a support base at the top and a base at the bottom. However, during the support process, as the support base rises, the overall center of gravity is unevenly distributed when only the base is used for support. This can cause the jack to become unbalanced, significantly affecting its stable support and thus its stability. Utility Model Content

[0004] The purpose of this invention is to provide a stable, self-balancing jack to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-balancing jack with stable support, comprising a jack body, a base fixedly installed at the bottom end of the jack body, a main support fixedly installed at the output end of the jack body, auxiliary support seats provided on both the left and right sides of the main support seat, the top ends of the auxiliary support seats and the top ends of the main support seats being on the same horizontal plane, an extension frame installed at the bottom end of each auxiliary support seat, a limiting guide rail provided on the side of the extension frame away from the jack body, the limiting guide rail being connected to the jack body by bolts, a self-balancing component being movably engaged at the bottom end of each limiting guide rail, and one end of the self-balancing component being connected to the extension frame.

[0006] When in use, place the device below the device to be lifted, and manipulate the jack body to move the main support seat upward. At this time, the main support seat and the auxiliary support seat can be moved upward as a whole until the main support seat and the auxiliary support seat contact the bottom of the device to be lifted and then lift it.

[0007] As a further technical solution of this utility model, a through groove is provided in the middle of the main support seat, and a threaded sleeve is movably installed inside the through groove. Threaded rods are movably installed in the middle of the two auxiliary support seats that are relatively close to one end.

[0008] As a further technical solution of this utility model, one end of the threaded rod passes through one end of the main support seat and is threadedly connected to the threaded sleeve. Guide rods are installed on both the front and rear sides of the auxiliary support seat that are relatively close to one end. The guide rods pass through one end of the main support seat and are movably engaged with the main support seat.

[0009] As a further technical solution of this utility model, when the threaded sleeve rotates, under the guidance of the guide rod and the main support seat, it drives the two auxiliary support seats to move closer or further apart.

[0010] By opening the threaded sleeve, the two threaded rods can be driven to move relative to each other under the action of the threaded sleeve and the threaded rod. At this time, the guide rod can drive the two auxiliary support seats to move relative to the main support seat under the guidance of the main support seat. The distance between the auxiliary support seats and the main support seat is adjusted accordingly, and the overall support area of ​​the device is adjusted accordingly, thereby improving the overall support stability.

[0011] As a further technical solution of this utility model, the self-balancing component includes a transverse mounting plate, a guide block is fixedly mounted on the top of the transverse mounting plate, and the transverse mounting plate is movably engaged with the limiting guide rail through the guide block. The self-balancing component also includes a longitudinal mounting plate, which is connected to the extension frame.

[0012] As a further technical solution of this utility model, the longitudinal mounting plate is equipped with first fixing seats on both the front and rear sides of the end away from the extension frame, and the transverse mounting plate is equipped with second fixing seats on both the front and rear sides of the bottom end.

[0013] As a further technical solution of this utility model, the end of the second fixed seat away from the horizontal mounting plate is movably connected to a linkage rod through a rotating shaft, and the end of the linkage rod away from the second fixed seat is movably connected to the first fixed seat through a rotating shaft. The bottom end of the horizontal mounting plate is fixedly installed with a support frame.

[0014] As the main support moves upward, the secondary support moves upward as well. At this time, the extension frame moves upward, driving the longitudinal mounting plate to move upward. The linkage rod then deflects downward and applies a thrust to the transverse mounting plate. The transverse mounting plate then moves under the guidance of the guide block and the limit rail, causing the bottom support frame to move away from the jack body, thus achieving self-balancing, increasing the support range, and improving support stability.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) By opening the threaded sleeve, the two threaded rods can be driven to move relative to each other under the action of the threaded sleeve and the threaded rod. At this time, the guide rod can drive the two auxiliary support seats to move relative to the main support seat under the guidance of the main support seat. At this time, the distance between the auxiliary support seats and the main support seats is adjusted accordingly. At this time, the overall support area of ​​the device is adjusted accordingly, thereby improving the overall support stability.

[0017] (2) By moving the main support seat upward, the auxiliary support seat is moved upward. At this time, the extension frame moves upward and drives the longitudinal mounting plate to move upward. At this time, the linkage rod deflects, that is, it deflects diagonally downward and applies a thrust to the transverse mounting plate. At this time, the transverse mounting plate can be displaced under the guidance of the guide block and the limiting guide rail, and drive the bottom support frame to move away from the jack body, thus achieving self-balancing, increasing the support range, and improving the support stability.

[0025] like Figures 1 to 5 As shown in the embodiment of this utility model, a self-balancing jack with stable support includes a jack body 1. A base 2 is fixedly installed at the bottom end of the jack body 1. A main support 3 is fixedly installed at the output end of the jack body 1. Auxiliary support 4 is provided on both the left and right sides of the main support 3. The top of the auxiliary support 4 and the top of the main support 3 are on the same horizontal plane. An extension frame 8 is installed at the bottom end of each auxiliary support 4. A limiting guide rail 9 is provided on the side of the extension frame 8 away from the jack body 1. The limiting guide rail 9 is connected to the jack body 1 by bolts. A self-balancing component 10 is movably engaged at the bottom end of each limiting guide rail 9. One end of the self-balancing component 10 is connected to the extension frame 8.

[0026] When in use, place the device below the device to be lifted, and manipulate the jack body 1 to move the main support 3 upward. At this time, the main support 3 and the auxiliary support 4 can move upward as a whole until the main support 3 and the auxiliary support 4 contact the bottom of the device to be lifted and lift it.

[0027] like Figure 1 and Figure 2 as well as Figure 3 As shown, a through groove is provided in the middle of the main support seat 3, and a threaded sleeve 6 is movably installed inside the through groove. Threaded rods 7 are movably installed in the middle of the two auxiliary support seats 4 at their respective ends. One end of the threaded rod 7 passes through one end of the main support seat 3 and is threadedly connected to the threaded sleeve 6. Guide rods 5 are installed on the front and rear sides of the auxiliary support seats 4 at their respective ends. The guide rods 5 pass through one end of the main support seat 3 and are movably engaged with the main support seat 3. When the threaded sleeve 6 rotates, under the guidance of the guide rods 5 and the main support seat 3, the two auxiliary support seats 4 are driven to move closer or further apart.

[0028] By opening the threaded sleeve 6, the two threaded rods 7 can be driven to move relative to each other under the action of the threaded sleeve 6 and the threaded rod 7. At this time, the guide rod 5 can drive the two auxiliary support seats 4 to move relative to the main support seat 3 under the guidance of the main support seat 3. The distance between the auxiliary support seats 4 and the main support seat 3 is adjusted accordingly, and the overall support area of ​​the device is adjusted accordingly, thereby improving the overall support stability.

[0029] like Figure 1 and Figure 4 as well as Figure 5As shown, the self-balancing assembly 10 includes a transverse mounting plate 101, with a guide block 107 fixedly mounted on the top of the transverse mounting plate 101. The transverse mounting plate 101 is movably engaged with the limiting guide rail 9 via the guide block 107. The self-balancing assembly 10 also includes a longitudinal mounting plate 102, which is connected to the extension frame 8. First fixed seats 104 are mounted on both the front and rear sides of the end of the longitudinal mounting plate 102 away from the extension frame 8. Second fixed seats 105 are mounted on both the front and rear sides of the bottom end of the transverse mounting plate 101. A linkage rod 106 is movably connected to the end of the second fixed seat 105 away from the transverse mounting plate 101 via a pivot. The ends of the linkage rod 106 away from the second fixed seat 105 are movably connected to the first fixed seat 104 via pivots. A support frame 103 is fixedly mounted on the bottom end of the transverse mounting plate 101.

[0030] As the main support 3 moves upward, the secondary support 4 moves upward, and the extension frame 8 moves upward as well, driving the longitudinal mounting plate 102 to move upward. At this time, the linkage rod 106 deflects downward and applies a thrust to the transverse mounting plate 101. The transverse mounting plate 101 then moves under the guidance of the guide block 107 and the limiting guide rail 9, and drives the bottom support frame 103 to move away from the jack body 1, thus achieving self-balancing, increasing the support range, and improving support stability.

[0031] Working principle and usage process:

[0032] When in use, place the device below the device to be lifted, and manipulate the jack body 1 to move the main support 3 upward. At this time, the main support 3 and the auxiliary support 4 can be moved upward as a whole until the main support 3 and the auxiliary support 4 contact the bottom of the device to be lifted and lift it.

[0033] When the threaded sleeve 6 is opened, the two threaded rods 7 can be driven to move relative to each other under the action of the threaded sleeve 6 and the threaded rod 7. At this time, the guide rod 5 can drive the two auxiliary support seats 4 to move relative to the main support seat 3 under the guidance of the main support seat 3. At this time, the distance between the auxiliary support seats 4 and the main support seat 3 is adjusted accordingly, and the overall support area of ​​the device is adjusted accordingly.

[0034] The upward movement of the main support seat 3 causes the auxiliary support seat 4 to move upward, and the extension frame 8 moves upward accordingly. At the same time, it drives the longitudinal mounting plate 102 to move upward. The linkage rod 106 deflects downward and applies a thrust to the transverse mounting plate 101. The transverse mounting plate 101 can then move under the guidance of the guide block 107 and the limiting guide rail 9, and drive the bottom support frame 103 to move away from the jack body 1, thus achieving self-balancing and increasing the support range.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
