DETAILED DESCRIPTION

[0017] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0018] This embodiment of Figure 2 Components such as legs and struts are omitted in the figure to facilitate clear observation of the internal structure of the hollow tube 1a.

[0019] like Figure 1 and Figure 2 The floor-standing vise bracket shown includes a central support column 1, a support platform 2 connected to the top of the central support column 1, and three legs 3 connected around the central support column 1. The three legs 3 support the central support column 1 so that the central support column 1 remains in a vertical state. The support platform 2 is horizontally arranged, and the central support column 1 is connected to the bottom surface of the support platform 2. The support platform 2 is used to connect the vise.

[0020] In this embodiment, the central support column 1 includes a hollow tube body 1a with openings at both ends and nuts 1b fixedly connected to the two ends of the hollow tube body 1a, respectively. The nut 1b is coaxially arranged with the center hole 1c of the hollow tube body 1a. The lower end of the central support column 1 is threadedly connected with a lower support screw 4, which is coaxial with the central support column 1. The lower support screw 4 can move up and down along the axial direction of the central support column 1. The lower end of the lower support screw 4 is connected with a support plate 5, the diameter of the support plate 5 is larger than the diameter of the lower support screw 4, and the support plate 5 is used to abut against the ground. The lower support screw 4 is threadedly connected to the nut 1b at the lower end of the central support column 1, and the top end of the lower support screw 4 passes through the nut 1b and is inserted into the hollow tube body 1a.

[0021] In this embodiment, an upper support screw 6 is threadedly connected to the top of the central support column 1. The upper support screw 6 is coaxially arranged with the central support column 1. The upper support screw 6 can move up and down along the axial direction of the central support column 1. The support platform 2 is connected to the top of the upper support screw 6. The upper support screw 6 is threadedly connected to the nut 1b at the top of the central support column 1, and the lower end of the upper support screw 6 passes through the nut 1b and is inserted into the hollow tube body 1a. A first locking pin 7 is threadedly connected to the upper side wall of the hollow tube body 1a, and one end of the first locking pin 7 passes through the side wall of the hollow tube body 1a and is inserted into the center hole 1c to abut against the side wall of the upper support screw 6. The first locking pin 7 is used to lock the upper support screw 6 so that the upper support screw 6 maintains an unchanged extended length.

[0022] like Figure 2As shown, the inner hole of the nut 1b described in this embodiment is smaller than the center hole 1c of the hollow tube body 1a, and a limit plate 8 is fixedly connected to the lower end of the upper support screw 6. The diameter of the limit plate 8 is larger than the inner diameter of the nut 1b and is adapted to the center hole 1c of the hollow tube body 1a.

[0023] The limiting piece 8 can not only prevent the upper support screw rod 6 from falling off the nut 1b upward, but also can improve the coaxiality between the upper support screw rod 6 and the hollow tube body 1a, thereby preventing the upper support screw rod 6 from tilting.

[0024] The three supporting legs 3 described in this embodiment are evenly distributed circumferentially around the central support column 1, and the top end of any supporting leg 3 is rotatably connected to the shaft seat 10 on the outer wall of the central support column 1 through a pin shaft 9. A sliding sleeve 11 is sleeved on the central support column 1 below the shaft seat 10, and a second locking pin 12 is threadedly connected to the sliding sleeve 11. One end of the second locking pin 12 passes through the sliding sleeve 11 and abuts against the outer wall of the central support column 1. Three support rods 13 are evenly distributed circumferentially on the sliding sleeve 11, and the three support rods 13 correspond to the three supporting legs 3 one by one. One end of any supporting rod 13 is hinged to the middle part of the corresponding supporting leg 3, and the other end is hinged to the sliding sleeve 11. The sliding sleeve 11 can adjust the opening of the three supporting legs 3.

[0025] The three legs 3 are supported by three support rods 13 connected to the sliding sleeve 11 , and the user can adjust the opening of the three legs 3 according to the actual ground conditions, and the height of the floor vise bracket can also be adjusted by adjusting the opening of the three legs 3 .

[0026] The support platform 2 is provided with a plurality of positioning long holes 14 uniformly distributed circumferentially with the central support column 1 as the center, and the long axis of each positioning long hole 14 extends radially outward along the central support column 1. The positioning long holes 14 are used to connect the bench vise, and the plurality of circumferentially uniformly distributed positioning long holes 14 enable the bench vise to be flexibly installed, fixed and adjusted on the support platform 2.

[0027] In this embodiment, a handle 15 is preferably connected to the outer wall of the central support column 1 to facilitate the user to carry it.

[0028] The working process of this utility model is: Figure 1 As shown, the user first loosens the second locking pin 12, slides the sleeve 11 to open the three legs 3 to a suitable opening, then tightens the second locking pin 12, the opening of the three legs 3 is locked, and places the floor vise bracket on the ground so that the three legs 3 are in good contact with the ground.

[0029] Next, the user turns the lower support screw 4 to make the support plate 5 tightly contact the ground.

[0030] Then, the user loosens the first locking pin 7 , rotates the support platform 2 to adjust the height of the support platform 2 , and after adjusting the support platform 2 to a suitable height, tightens the first locking pin 7 to lock the upper support screw 6 .

[0031] Finally, the user assembles the vise onto the supporting platform 2 and uses the vise to clamp the workpiece for processing.

[0032] The utility model uses a central support column 1 and a support platform 2 to support the bench vise, and uses a support leg 3 to maintain the vertical state of the central support column 1, thereby simplifying the overall structure of the bench vise bracket, achieving lightweight bench vise bracket, and facilitating transfer. At the same time, the utility model uses a lower support screw 4 and a support plate 5 threadedly connected to the central support column 1 to allow the lower end of the central support column 1 to be directly supported by the ground, thereby improving the bearing capacity and bearing stability of the support platform, ensuring that the bench vise connected to the support platform can provide strong support to the clamped workpiece when in use, and can withstand a large stamping force.

[0033] The above embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
