Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of jacks, in particular to an adjusting mechanism and a movable scissor-type jack vise bracket. Background Art
[0002] Traditional scissor jacks only have a simple lifting function. In the process of lifting objects, there is a lack of fixing devices, which may cause the objects to overturn or shift during the lifting process. At the same time, traditional scissor jacks can only work at fixed points. Uneven force during the lifting process can also cause displacement. After the object is lowered, the jack cannot move and cannot be corrected in time, resulting in deviation from the original position of the object. For example, in the maintenance of the working seal of the hydro-turbine generator, it is usually necessary to lift the working seal cover plate, check and replace the sealing rubber ring of the cover plate. The traditional method is to use a jack to support the arms in the four directions of the working seal cover plate. However, due to the lack of a fastening device on the jack and the asynchronous operation, the force on the jack in each direction is uneven, and the working seal cover plate will be offset. After the maintenance, the position of the cover plate needs to be manually adjusted. During the adjustment process, the jack cannot move, resulting in time-consuming and laborious adjustment of the cover plate. At the same time, the jack is slow to reset when in use, which is a waste of time.
[0003] Therefore, we have designed an adjustment mechanism and a movable scissor jack vise bracket, which can quickly reset, fix the vise workbench, and facilitate the movement of the vise workbench. Utility Model Content

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0032] Example 1
[0033] Reference Figure 1 , which is the first embodiment of the utility model, and this embodiment provides an adjustment mechanism, which can achieve the effect of quickly resetting the jack, and includes a lifting component 100 and an adjustment component 200. By setting the lifting component 100, the vise workbench can be slowly lifted up, and by setting the adjustment component 200, the jack can be quickly reset after using the jack, saving time.
[0034] Specifically, the lifting assembly 100 includes a threaded rod 101, two groups of connecting blocks 102 slidably connected to both sides of the threaded rod 101, and a lifting portion 103 disposed between the two groups of connecting blocks 102; by arranging the threaded rod 101, the connecting blocks 102, and the lifting portion 103, the vise workbench can be lifted up, and the threaded rod 101 is rotated so that the two groups of connecting blocks 102 move on the threaded rod 101, driving the vertical height of the lifting portion 103 to increase. The threaded rod 101 is a bidirectional threaded rod, and when rotating, it drives the two groups of connecting blocks 102 to move inward or outward at the same time.
[0035] Furthermore, an adjustment component 200 is arranged inside the connecting block 102, and includes two groups of clamping blocks 201 slidably arranged inside the connecting block 102, an adjustment member 202 connected between the two groups of clamping blocks 201, a positioning member 203 arranged between the adjustment member 202 and the connecting block 102, a limiting member 204 arranged between the two groups of clamping blocks 201 and the connecting block 102, a reset portion 205 arranged on one side of the threaded rod 101, and two groups of locking members 206 arranged between the top end of the clamping block 201 and the connecting block 102. When in use, the rotating positioning piece 203 drives the adjusting piece 202 so that the two groups of clamping blocks 201 can be separated and closed. When the two groups of clamping blocks 201 are closed, they can cooperate with the threaded rod 101, so that the connecting block 102 and the threaded rod 101 are threadedly connected, and the lifting part 103 can be driven. When the two groups of clamping blocks 201 are separated, the connecting block 102 and the threaded rod 101 are slidably connected, and the lifting part 103 is pressed downward to quickly descend and reset the jack.
[0036] Operation process: when in use, when the jack needs to be lifted, the positioning member 203 is rotated to drive the adjusting member 202 to close the two groups of clamping blocks 201 and cooperate with the threaded rod 101. By rotating the threaded rod 101, the two groups of connecting blocks 102 are driven to move inward on the threaded rod 101, so that the vertical height of the lifting part 103 becomes higher, and the vise workbench is slowly lifted; when it needs to be reset, the positioning member 203 is rotated to drive the adjusting member 202 to separate the two groups of clamping blocks 201, and press downward to move the two groups of connecting blocks 102 on the threaded rod 101 outward, so that the vertical height of the lifting part 103 becomes lower, and the jack can be quickly reset.
[0037] In summary, by providing the lifting assembly 100 and the adjusting assembly 200, it is possible to lift the vise workbench and reset the jack.
[0038] Example 2
[0039] Reference Figures 2~6, which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides further optimization of the adjustment mechanism and solves the problem of how to reset the jack. It includes the lifting part 103 including a first lifting member 103a and a second lifting member 103b connected between two groups of connecting blocks 102 and symmetrically arranged. The first lifting member 103a and the second lifting member 103b have exactly the same structure and both include two groups of lifting arms 103a-1 respectively connected to the connecting blocks 102, and a gear group 103a-2 arranged between the two groups of lifting arms 103a-1; wherein the gear group 103a-2 is rotatably connected between the two groups of positioning plates 103e. When in use, when the two sets of connection blocks 102 move inward at the same time, the two sets of lifting arms 103a-1 connected to the upper and lower sides of the connection block 102 move with the movement of the connection block 102, and the ends of the two sets of lifting arms 103a-1 connected to the connection block 102 move inward, while the positions of their other ends do not move, thereby increasing the vertical height of the two sets of lifting arms 103a-1. The gear set 103a-2 includes four gears, which are respectively arranged on the two sets of lifting arms 103a-1. Two gears are arranged at the ends of the lifting arms 103a-1. The two gears are connected by a rotating rod. The gears between the two sets of lifting arms 103a-1 are meshed with each other, so that the jack has good synchronization in rising and falling.
[0040] Specifically, the adjusting member 202 includes a positioning rod 202a disposed on the clamping block 201 and a rotating block 202b slidably connected to the positioning rod 202a; wherein the rotating block 202b is provided with two sets of centrally symmetrical sliding grooves 202c, in which the positioning rod 202a is slidably disposed, and the sliding grooves 202c are obliquely disposed on the rotating block 202b; there is a gap between the end of the positioning rod 202a and the sliding grooves 202c. By rotating the rotating block 202b, the two sets of clamping blocks 201 can be separated and closed. When rotating, since the sliding grooves 202c are disposed on the rotating block 202b, when the rotating block 202b rotates, the positioning rod 202a is driven to move on the sliding grooves 202c, thereby driving the two sets of clamping blocks 201 to move.
[0041] Furthermore, the positioning member 203 includes a rotating shaft 203a fixedly connected to the rotating block 202b and threadedly connected to the connecting block 102, and a rotating wheel 203b fixedly connected to the rotating shaft 203a. The rotating wheel 203b drives the rotating shaft 203a to rotate, thereby driving the rotating block 202b to rotate; the rotating shaft 203a and the connecting block 102 are threadedly connected, so that the rotating block 202b can be rotated to a certain angle and fixed. There is a certain distance between the inner bottom end of the sliding groove 202c of the rotating block 202b and the end of the positioning rod 202a, so that the rotating shaft 203a is not limited when the thread rotates.
[0042] The limiting member 204 includes limiting blocks 204a connected to both sides of the clamping block 201, and positioning grooves 204b arranged inside the connecting block 102 and matching with the limiting blocks 204a. The limiting blocks 204a and the positioning grooves 204b enable the two groups of clamping blocks 202a to only move up and down under the drive of the positioning rod 202a, and will not rotate with the positioning rod 202a.
[0043] Furthermore, when the positioning rod 202a is located at one end of the slide groove 202c close to the center of the circle, the two groups of clamping blocks 201 are pressed against each other, and the end of the positioning rod 202a is pressed against the inside of the slide groove 202c; when the positioning rod 202a is located at one end of the slide groove 202c away from the center of the circle, the two groups of clamping blocks 201 are separated from each other, and the end of the positioning rod 202a is away from the inside of the slide groove 202c. When the two groups of clamping blocks 201 are closed, the positioning rod 202a is located at one end of the slide groove 202c close to the center of the circle, and the end of the positioning rod 202a is in close contact with the inside of the slide groove 202c. At this time, the rotating block 202b is fixed in position due to the threaded connection between the rotating shaft 203a and the connecting block 102, so that the two groups of clamping blocks 201 are in close contact; when the two groups of clamping blocks 201 need to be separated, the rotating shaft 203a is rotated clockwise to drive the rotating block 202b to rotate clockwise, driving the positioning rod 202a to move in the slide groove 202c, and move to the end of the slide groove 202c away from the center of the circle. At this time, there is a distance between the end of the positioning rod 202a and the inside of the slide groove 202c.
[0044] Preferably, the reset portion 205 includes a reset shaft 205a disposed on one side of the threaded rod 101, a power member 205b slidably connected to one side of the reset shaft 205a, and a reset member 205c disposed between the threaded rod 101 and the connecting block 102. The reset portion 205 is used to reset the threaded rod 101 so that the threaded rod 101 can still mesh with each other after the two sets of clamping blocks 201 are separated and closed.
[0045] Furthermore, the power member 205b includes a pressing rod 205b-1 slidably connected to the threaded rod 101, a bevel block 205b-2 fixedly connected to the pressing rod 205b-1, and a return spring 205b-3 arranged between the bevel block 205b-2 and the threaded rod 101; the return member 205c includes a connecting rod 205c-1 abutting against the bevel block 205b-2 and slidably connected to the threaded rod 101, and a return groove 205c-2 arranged on the connecting block 102 and matching the connecting rod 205c-1. When in use, the pressing rod 205b-1 is pressed inward, so that the inclined block 205b-2 moves inward, and the connecting rod 205c-1 moves upward and extends out of the interior of the threaded rod 101. The threaded rod 101 is then rotated so that the connecting rod 205c-1 matches the reset groove 205c-2 on the connecting block 102, so that the two sets of clamping blocks 201 and the threaded rod 101 return to the initial state and engage with each other.
[0046] The locking member 206 includes a connecting shaft 206a slidably connected to the connecting block 102, an inner rod 206b disposed inside the connecting shaft 206a and slidably connected to the connecting shaft 206a, a telescopic spring 206c disposed between the inner rod 206b and the connecting shaft 206a, and a ball pin 206d slidably connected to the connecting shaft 206a and matched with the end of the inner rod 206b. The locking member 206 is used to limit the separation of the two groups of clamping blocks 201. The lower end of the inner rod 206b of the locking member 206 is provided with a groove, and the connecting shaft 206a is provided with a positioning groove. The outer diameter of the positioning groove is smaller than the diameter of the ball pin 206d. In the initial state, the position of the groove is higher than the position of the ball pin 206d, and the end of the inner rod 206b is in conflict with the ball pin 206d. When in use, the inner rod 206b is pressed downward so that the groove is downward and just at the position of the ball pin 206d, so that the ball pin 206d is contracted inward. , and then the connecting shaft 206a is inserted into the bottom and upper ends of the connecting block 102 as a whole, and then the force pressing the inner rod 206b is released, so that the inner rod 206b moves upward and resets under the action of the telescopic spring 206c, so that the position of the groove is relocated to the upper end of the ball pin 206d, and the ball pin 206d is pressed by the end of the inner rod, and extends outward, just against the inner wall of the connecting block 102, so that the locking member 206 is fixed between the connecting block 102 and the clamping block 201, and further the connection between the two sets of clamping blocks 201 is tightened. The place where the end of the inner rod 206b conflicts with the ball pin 206d is vertical.
[0047] Operation process: when in use, remove the locking piece 206, rotate the rotating shaft 203a clockwise, drive the rotating block 202b to move clockwise, drive the two groups of clamping blocks 201 to separate, and do not mesh with the threaded rod 101. The threaded rod 101 is slidably connected inside the connecting block 102 and the mounting block 103, and the lifting part 103 is pressed downward to quickly reduce the vertical height of the lifting part 103 and reset the jack. When the jack is needed, press the pressing rod 205b-1 inward to move the inclined block 205b-2 inward, so that the connecting rod 205c-1 moves upward and extends out of the threaded rod 101. Then rotate the threaded rod 101 so that the connecting rod 205c-1 matches the reset groove 205c-2 on the connecting block 102. Rotate the rotating shaft 203a counterclockwise to drive the rotating block 202b to move counterclockwise, drive the two groups of clamping blocks 201 to clamp, and then install the locking piece 206.
[0048] In summary, by providing two groups of clamps 201, adjusting members 202, positioning members 203, limiting members 204, and resetting members 205, the jack can be quickly reset, and the threaded rod 101 can also be reset, so that the threaded rod 101 and the two groups of clamps 201 are engaged.
[0049] Example 3
[0050] Reference Figure 7 , 8 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a movable scissor-type jack vise bracket, which solves the problem of how to fix the vise workbench and move the jack. It includes a fixed component 300, which is arranged at the top of the lifting part 103, including a fixed top plate 301 connected to the top of the two groups of positioning plates 103e, and a fixing member 302 arranged at the upper end of the fixed top plate 301; a moving component 400, which is arranged at the bottom of the lifting part 103, including a bottom plate 401 connected to the bottom of the two groups of positioning plates 103e, and pulleys 402 fixedly connected to the four corners of the bottom of the bottom plate 401. By setting the fixed component 300, the arm of the vise workbench can be fixed to prevent the object from overturning or displacement during the lifting of the heavy object. The moving component 400 can easily move the jack, which solves the problem that the jack can only work at a fixed point, and the jack cannot move and cannot correct the deviation in time after the object is lowered, resulting in deviation from the original position of the object. In the present invention, the pulley 402 is a lockable universal wheel.
[0051] Specifically, the fixing member 302 includes a sliding seat 302a disposed on the upper end of the fixed top plate 301, a fixed clamping plate 302b fixedly disposed on one side of the sliding seat 302a, a support frame 302c fixedly disposed on the other side of the sliding seat 302a, a sliding clamping plate 302d disposed between the fixed clamping plate 302b and the support frame 302c and slidably connected to the sliding seat 302a, and a rotating rod 302e fixedly connected to the sliding clamping plate 302d and threadedly connected to the support frame 302c. When in use, the position of the sliding clamping plate 302d is adjusted by the rotating rod 302e according to the width of the arm of the vise workbench, so that the arm is fixed between the sliding clamping plate 302d and the fixed clamping plate 302b.
[0052] Operation process: When in use, place the arm of the bench vise workbench on the sliding seat 302a, rotate the rotating rod 302e, move the position of the sliding clamp 302d, fix the arm, and the jack moves its position through the universal wheel that can be locked at the bottom.
[0053] In summary, by providing the fixed assembly 300 and the movable assembly 400, it is possible to fix the arm of the vise workbench and move the jack.
