Description

Technical Field

[0001] The utility model relates to a locking slider with a locking strip, in particular to a locking slider with a locking strip, and belongs to the technical field of locking strip locking. Background Art

[0002] A locking bar, also called a locking bar or clamping bar, is a mechanical device used to fix and clamp a workpiece. It usually consists of a movable lever, a screw and a clamping block. When the screw is rotated, the clamping block (slider) is moved and clamps the workpiece, thereby achieving the purpose of locking. Locking bars are widely used in machining, assembly lines and other fields where workpieces need to be fixed.

[0003] Most of the current locking strips adjust the position of the slider by setting an inclined limit groove, or use a spring to move the slider. Although this method can change the position of the slider and have a locking effect, the slider itself cannot be reset but can be moved away from the lever, which causes the slider to always be in a loose state, thus affecting the stability of the locking strip.

[0025] The embodiment of the utility model provides a locking slider with a locking strip.

[0026] See also Figures 1 to 5 , including a rod body 1, a fixed wedge block 2 distributed in a linear array is slidably connected to the outer side of the rod body 1, a sliding wedge block 3 is slidably connected between each two adjacent fixed wedge blocks 2, an adjusting component for adjusting the movement of the fixed wedge block 2 is provided on the rod body 1, a locking component is provided in the sliding wedge block 3, the locking component includes a rack rod 4 and a gear ring 5 meshingly connected to each other, the rack rod 4 and the gear ring 5 are respectively arranged on two fixed wedge blocks 2 adjacent to the sliding wedge block 3, a first threaded rod 6 is threadedly connected in a first threaded hole opened on the upper part of the gear ring 5, the top end of the first threaded rod 6 is fixedly connected to a limiting block 7, and a sliding groove 15 slidably connected to the limiting block 7 is formed on the top wall inside the sliding wedge block 3;

[0027] When the fixed wedge blocks 2 at both ends are squeezed close to each other and then pulled away from each other, the rack rod 4 on the fixed wedge block 2 will drive the gear ring 5 to rotate, so that the gear ring 5 drives the first threaded rod 6 to rise and fall, and thus the first threaded rod 6 is lifted and lowered together with the sliding wedge block 3. Due to the limitation of the gear ring 5, any rising height of the sliding wedge block 3 is in a locked state, and there will be no problem of rising or falling on its own.

[0028] The inner walls of both sides of the fixed wedge block 2 are provided with wire grooves, and wire rods are installed at both ends of the rod body 1. The wire rods are slidably connected with the wire grooves, so that the fixed wedge block 2 can only slide on the rod body 1, and cannot be separated from the rod body 1 by lifting;

[0029] The sliding wedge block 3 is a sliding block. When the sliding wedge block 3 is lifted or lowered, due to the change in position, the first threaded rod 6 will slide on the inner wall of the sliding wedge block 3 through the limit block 7, and the setting of the slide groove 15 can make the limit block 7 but cannot rotate, so that the first threaded rod 6 can only be lifted or lowered but cannot rotate.

[0030] See also Figure 1 and Figure 4 The adjustment assembly includes an adjustment plate 19 and a second threaded rod 8, one end of the rod body 1 is fixedly connected to the fixed wedge block 2 at the leftmost end, the second thread groove provided at the other end of the rod body 1 is threadedly connected to one end of the second threaded rod 8, the adjustment plate 19 is rotatably sleeved on the other end of the second threaded rod 8, and the adjustment plate 19 is installed on one side of the fixed wedge block 2 at the rightmost end;

[0031] By rotating the second threaded rod 8, the adjusting plate 19 is moved closer to or farther away from the fixed wedge block 2 at the rightmost end, so that the fixed wedge block 2 presses the sliding wedge block 3 to rise, thereby utilizing the sliding wedge block 3 to block the movement of the object and lock it.

[0032] See also Figure 5 , two tenon rods 9 are fixedly connected to both sides of the sliding wedge block 3, and a tenon groove 10 is provided at a corresponding position of the fixed wedge block 2 relative to the tenon rod 9, and the tenon groove 10 is slidably connected to the tenon rod 9;

[0033] The way in which the tenon rod 9 and the tenon groove 10 slide relative to each other is to limit the range of motion of the sliding wedge block 3 so that the sliding wedge block 3 can only slide on the surface of the fixed wedge block 2 .

[0034] See also Figure 2 The sliding wedge block 3 is sleeved on the outside of the rod body 1, and the rod body 1 is located below the rack rod 4.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 , the upper part of the gear ring 5 is rotatably connected with a connecting plate 17, and both ends of the fixed wedge block 2 are provided with slots 11, and the two slots 11 are plug-connected with one end of the connecting plate 17 and one end of the rack rod 4 respectively, and a through hole is formed on the inner wall of one side of the slot 11, and a fourth threaded rod 18 is plug-connected in the through hole, and the rack rod 4 and the connecting plate 17 are provided with a fourth thread groove at the corresponding positions relative to the through hole, and a nut is fixedly connected to one end of the fourth threaded rod 18, and the other end of the fourth threaded rod 18 is threadedly connected to the fourth thread groove;

[0036] The slot 11 is provided to facilitate the disassembly and assembly of the connecting plate 17 and the rack rod 4, and the fourth threaded rod 18 is used to fix the connecting plate 17 or the rack rod 4 in the slot 11;

[0037] The connecting plate 17 is provided with a connecting opening, and the fourth threaded rod 18 is inserted into the connecting opening.

[0038] See also Figure 5 A rotating hole is provided at the end of the fixed wedge block 2 on the far left, and a limit rod 14 is rotatably connected in the rotating hole. An external thread is provided at the movable end of the limit rod 14, and a limit groove threadably connected to the external thread of the limit rod 14 is provided at a corresponding position of the rod body 1 relative to the rotating hole;

[0039] By threading the movable end of the limiting rod 14 with the limiting groove, the rod body 1 and the corresponding fixed wedge block 2 can be fixed to each other, thereby facilitating the disassembly and assembly of the fixed wedge block 2 and the rod body 1.

[0040] See also Figure 1 and Figure 4 A through first opening 12 is formed on the upper portion of the fixed wedge block 2, and a second opening 13 is formed on the rod body 1 at a position corresponding to the first opening 12;

[0041] The first opening 12 is for convenient insertion of a screw, so that the screw can fall into the second opening 13, and the screw is inserted into the second opening 13, thereby fixing the rod body 1 on the object;

[0042] The first opening 12 has a diameter larger than the outer diameter of the nut on the screw, while the second opening 13 has a diameter smaller than the outer diameter of the nut but larger than the outer diameter of the screw rod;

[0043] When the rod body 1 is fixed with screws, the position of the fixing wedge block 2 needs to be adjusted in advance so that the first through opening 12 and the second through opening 13 on the fixing wedge block 2 correspond to each other.
