Description

Technical Field

[0001] This application relates to the technical field of jacks, and in particular to an electric horizontal jack. Background Technology

[0002] During vehicle repair, it is usually necessary to use a jack to lift the vehicle in order to repair problems on the underside.

[0003] Currently, most jacks are hydraulic or mechanical, requiring manual operation. This usually involves rotating the lever or pressing the crossbar to gradually lift the load, which requires a lot of physical effort from the operator, making jack use time-consuming and labor-intensive.

[0004] Therefore, a new technical solution is needed to address the above problems. Summary of the Invention

[0005] To make lifting the jack easier, this application provides an electric horizontal jack.

[0006] This application provides an electric horizontal jack, which adopts the following technical solution:

[0007] An electric horizontal jack includes a base and a lifting plate rotatably connected to the base. One end of the lifting plate away from its rotation axis can abut against the lower end of a heavy object. The base is provided with a drive mechanism that drives the end of the lifting plate away from the rotation axis to move toward the heavy object. The drive mechanism includes a half-tooth fixed to the lifting plate, a plurality of connecting gears rotatably connected to the base, a drive gear rotatably connected to the base, a motor that drives the drive gear to rotate, and a battery that supplies power to the motor. The connecting gears mesh with the half-tooth and the drive gear respectively.

[0008] By adopting the above technical solution, the motor drives the drive gear, connecting gear and half gear to rotate, which in turn drives the lifting plate to rotate upward near the heavy object, thereby lifting the heavy object. During the lifting process, there is no need to manually drive the sleeve to rotate, which makes the use of the jack more labor-saving.

[0009] Optionally, the base is also provided with a manual mechanism for manually rotating the half-tooth. The manual mechanism includes a first bevel gear coaxially fixed to the drive gear, a second bevel gear rotatably connected to the base, and a rotating block coaxially fixed to the second bevel gear. The first bevel gear meshes with the second bevel gear, and the rotating block is located at the end of the base away from the lifted object.

[0010] By adopting the above technical solution, even when the battery is disconnected, force is applied to the rotating block and transmitted through the second bevel gear and the first bevel gear, thereby driving the lifting plate to continue moving up and down, so that the jack can still be used normally even when the battery is disconnected.

[0011] Optionally: The base is provided with a handle that drives the base to move. The handle includes a fixed sleeve rod rotatably connected to the base, a rotating rod passing through the fixed sleeve rod, and a connector provided on the rotating rod. The connector can be connected to both the rotating rod and the fixed sleeve rod at the same time. One end of the rotating rod located inside the fixed sleeve rod is provided with a rotating groove. The rotating block can be inserted into the rotating groove, and the side wall of the rotating block can abut against the inner wall of the rotating groove.

[0012] By adopting the above technical solution, when it is necessary to rotate the rotating block, the rotating rod is taken out from the fixed sleeve, and then the rotating block is connected to the rotating rod. The rotating rod is then used to drive the rotating block to rotate, which can drive the rotating block to rotate from a greater distance, thereby making the use of the jack safer.

[0013] Optionally: The connecting member includes a retaining ring that rotates coaxially on the rotating rod and a connecting sleeve that is coaxially fixed on the retaining ring. The connecting sleeve is sleeved outside the fixed sleeve rod and threadedly engaged with the fixed sleeve rod.

[0014] By adopting the above technical solution, the rotating rod is connected to the fixed sleeve rod using a connector. When the rotating rod is not needed, it will not detach from the fixed sleeve rod under force, thus making the normal movement of the jack less affected.

[0015] Optionally: The outer wall of the rotating rod is circumferentially fixed with several extension rods, and the outer wall of the fixed sleeve is circumferentially provided with several relief grooves communicating with its inner cavity. The relief grooves pass through the end face of the fixed sleeve away from the base, and the extension rods can pass through the relief grooves.

[0016] By adopting the above technical solution, when it is necessary to use the rotating rod to drive the rotating block to rotate, the rotating rod can be driven to rotate by applying force to the extension rod. During the rotation of the rotating rod, there is a position where force can be directly applied, which makes the rotation of the rotating rod more convenient. Furthermore, when the rotating rod is inserted into the fixed sleeve rod, the extension rod is used to restrict the rotation of the rotating rod relative to the fixed sleeve rod, so that the movement of the jack is not easily affected.

[0017] Optionally: The end of the rotating rod away from the rotating groove has a gripping element that rotates coaxially.

[0018] By adopting the above technical solution, when connecting the rotating rod and the rotating block, the connection between the rotating rod and the rotating block is kept stable by applying force to the gripping member, and the normal rotation of the rotating rod is not easily affected by the rotational connection between the gripping member and the rotating rod.

[0019] Optionally: The gripping member includes a connecting rod rotatably connected to the rotating rod and a gripping rod hinged to the connecting rod. A gripping ring is fixed at the end of the gripping rod away from the connecting rod. The gripping ring can abut against the ground and a gap is left between the extension rod and the ground.

[0020] By adopting the above technical solution, when using the rotating rod to rotate the rotating block, the gripping ring is rotated downwards until it touches the ground and is stepped on, thereby stabilizing the position of the rotating rod. Then, force can be applied to the extension rod with both hands, making the rotation of the rotating block more convenient.

[0021] Optionally: A limiting sleeve is coaxially sleeved on the gripping rod, and the limiting sleeve can be sleeved on both the gripping rod and the connecting rod simultaneously.

[0022] By adopting the above technical solution, the axis of the connecting rod and the gripping rod is limited by the limiting sleeve, so that the gripping ring will not rotate downward when the rotating rod is not in use, thus making the normal use of the jack less affected.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a motor to drive the lifting plate to move vertically, the lifting plate no longer needs to be moved by manually shaking the crossbar during the use of the jack, thus making the use of the jack more convenient.

[0025] 2. By setting a manual mechanism, the lifting platform can be moved vertically by rotating the rotating shaft after the battery is disconnected, so that the normal use of the jack is not easily affected. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses an electric horizontal jack, such as Figure 1 , Figure 2As shown, the system includes a base 1 and a lifting plate 11 rotatably connected to the base 1. An abutment plate 14 is rotatably connected to the end of the lifting plate 11 away from its axis of rotation. The upper end of the abutment plate 14 can abut against the lower end of the load. The lifting plate 11 is hollow, with the end away from the load being closed, thereby increasing the overall strength of the lifting plate 11 and saving material when lifting the same weight. A support rod 13 is also rotatably connected to the base 1. The other end of the support rod 13 is hinged to the lower end of the abutment plate 14. The support rod 13 is curved, with the end away from the abutment plate 14 inclined upwards. The end of the support rod 13 away from the abutment plate 14 is close to the axis of rotation of the lifting plate 11. The axis of rotation of the support rod 13 and the base 1 is located on the side of the axis of rotation of the lifting plate 11 and the base 1, closer to and slightly below the abutment plate 14. The base 1 is also equipped with a drive mechanism 2 that drives the lifting plate to rotate. The drive mechanism 2 includes a half-tooth 21 fixed to the lifting plate, several connecting gears 22 rotatably connected to the base, a drive gear 23 rotatably connected to the base, a motor 25 that drives the drive gear 23 to rotate, and a battery 26 that supplies power to the motor 25. The rotation axis of the half-tooth 21 coincides with the rotation axis of the lifting plate. The connecting gears 22 mesh with each other, and the connecting gears 22 located on both sides mesh with the half-tooth 21 and the drive gear 23 respectively. There can be one or two half-tooths 21. When there is one half-tooth 21, it is located in the middle of the rotation axis of the lifting plate 11. When there are two half-tooths 21, they are located near the two ends of the axis of the lifting plate 11 respectively. The motor 25 is fixed to the base 1 with bolts. The output shaft of the motor 25 is connected to the drive gear 23 through a coupling. The battery 26 is electrically connected to the motor 25. The motor 25 drives the drive gear 23, the connecting gear 22 and the half-tooth 21 to rotate, thereby moving the end of the lifting plate 11 away from the half-tooth 21, thus lifting the heavy object. No manual work is required during the lifting process, making the use of the jack more labor-saving.

[0032] like Figure 2As shown, since the battery 26 may run out of power, manual operation of the lifting platform 11 is required to raise and lower it. Therefore, the base 1 is also equipped with a manual mechanism 3 that manually drives the half-tooth 21 to rotate. The manual mechanism 3 includes a first bevel gear 31 coaxially fixed to the drive gear 23, a second bevel gear 32 rotatably connected to the base 1, and a rotating block 33 coaxially fixed to the second bevel gear 32. The first bevel gear 31 meshes with the second bevel gear 32, and the second bevel gear 32 is horizontally positioned. The rotating block 33 is coaxially fixed to the end of the second bevel gear 32 away from the half-tooth 21, and the cross-section of the end of the rotating block 33 away from the first bevel gear is a regular octagon. The rotation axis of the rotating block 33 forms an upward angle of 0 to 45 degrees with the horizontal plane. A protective sleeve 15 is also fitted over the base 1, and the protective sleeve 15 is coaxially positioned outside the rotating block 33 and covers the rotating block 33 inside. After the battery 26 is de-energized, force is applied to the rotating block 33 to drive the half tooth 21 to continue rotating, thereby realizing the raising and lowering of the lifting plate 11.

[0033] like Figure 1 and Figure 3 As shown, a handle 4 is rotatably connected to one end of the base 1 and the rotating block 33. The handle 4 is horizontally aligned with the rotation axis of the base 1. The handle 4 includes a fixed sleeve rod 41 rotatably connected to the base 1, a rotating rod 42 passing through the fixed sleeve rod 41, and a connecting member 43 on the rotating rod 42. The end of the fixed sleeve rod 41 away from the base 1 is open, allowing the rotating rod 42 to pass through it, with the outer wall of the rotating rod 42 abutting against the inner wall of the fixed sleeve rod 41. The connecting member 43 includes a retaining ring 431 coaxially rotating on the outer wall of the rotating rod 42 and a connecting sleeve 432 coaxially fixed to the retaining ring 431. The connecting sleeve 432 can be fitted onto the outer wall of the fixed sleeve rod 41 and threadedly engaged with it. The retaining ring 431 abuts against the end of the fixed sleeve rod 41 away from the base 1, thereby limiting the rotation angle between the connecting sleeve 432 and the fixed sleeve rod 41. The rotating rod 42, located within the fixed sleeve 41, has a rotating groove 421 that engages with the rotating block 33. The rotating groove 421 has a regular octagonal cross-section, and the outer wall of the rotating block 33 abuts against the inner wall of the rotating groove 421. When manual driving of the half-tooth 21 is not required, the rotating rod 42 is inserted into the fixed sleeve 41 and can normally push the base 1 to move. When manual rotation of the half-tooth 21 is required, the rotating rod 42 is removed from the fixed sleeve 41 and connected to the rotating block 33. The rotating rod 42 drives the rotating block 33 to rotate, thereby allowing the half-tooth 21 to continue rotating.

[0034] like Figure 3As shown, the surface of the rotating rod 42 is relatively smooth, making its rotation difficult. Therefore, two extension rods 44 are circumferentially arranged on the outer wall of the rotating rod 42. The extension rods 44 are perpendicular to the rotating rod 42, so that when the rotating rod 42 rotates, force is applied to the extension rods 44, providing a direct force application point to drive the rotating rod 42 to rotate, making the rotation of the rotating rod 42 easier.

[0035] like Figure 3 As shown, two relief grooves 411 are provided circumferentially on the outer wall of the fixed sleeve rod 41. The relief grooves 411 are connected to the inner cavity of the fixed sleeve rod 41, and the relief grooves 411 pass through the end of the fixed sleeve rod 41 away from the base 1. The extension rod 44 can be set in the relief groove 411 and abut against the inner wall of the relief groove 411, thereby restricting the rotation of the rotating rod 42 relative to the fixed sleeve rod 41.

[0036] like Figure 3 As shown, when connecting and rotating the rotating rod 42 and the rotating block 33, a force needs to be applied to the rotating rod 42 towards the rotating block 33 to maintain the connection. Therefore, a gripping member 5 is coaxially rotatably connected to the end of the rotating rod 42 away from the rotating groove 421. The gripping member 5 includes a connecting rod 51 rotatably connected to the rotating rod 42 and a gripping rod 52 hinged to the connecting rod 51. A gripping ring 53 is welded to the end of the gripping rod 52 away from the connecting rod 51. The gripping ring 53 has a semi-circular profile and can abut against the ground, while a gap is left between the extension rod 44 and the ground. After connecting the rotating rod 42 and the rotating block 33, the gripping rod 52 is rotated downwards to make the gripping ring 53 abut against the ground. Then, force is applied to the gripping ring 53 with the feet to limit the position of the gripping ring 53, so that both hands can contact the extension rod 44 and drive the extension rod 44 to rotate.

[0037] like Figure 3 As shown, a limiting sleeve 54 is also fitted on the gripping rod 52. The limiting sleeve 54 can rotate with the gripping rod 52, and the limiting sleeve 54 can be fitted on both the gripping rod 52 and the connecting rod 51 at the same time. The limiting sleeve 54 limits the alignment of the axes of the gripping rod 52 and the connecting rod 51, so that the gripping ring 53 can be gripped normally when the base 1 is moved by the gripping ring 53.

[0038] The implementation principle of this embodiment is as follows: During use, force is applied to the fixed sleeve rod 41 to move the base 1 to the area below the heavy object to be lifted. The motor 25 rotates, thereby driving the lifting plate 11 to rise and lifting the heavy object. When the battery 26 is de-energized, the connecting sleeve 432 is rotated to disengage it from the fixed sleeve rod 41. The rotating rod 42 is removed from the fixed sleeve rod 41, and the rotating block 33 is connected to the rotating groove 421. The limiting sleeve 54 is moved toward the gripping ring 53 and disengaged from the connecting rod 51. The gripping ring 53 is rotated downward and stepped on, and force is applied to the extension rod 44 to move the lifting plate 11.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
