Technical Field
[0001] The utility model relates to the technical field of anchor rods, in particular to an anchor rod with adjustable length. Background Art
[0002] At present, in foundation pit or slope support projects such as construction, water conservancy, and highway, anchor rods are commonly used support forms. Among them, the high-pressure jet grouting conical anchor rod is a kind of anchor rod. Although the anchor rod is convenient for assisting slope construction for support, inevitably, in the actual use process, there are still deficiencies. For example, the device lacks a length adjustment mechanism, resulting in the length of the anchor rod needing to be matched and customized according to the actual length of the anchor hole, which further causes the problem that the actual use range of the anchor rod is relatively limited. In order to avoid such problems, an anchor rod with adjustable length is proposed to solve the existing problems. Summary of the Utility Model
[0003] Aiming at the technical problems existing in the background art, the utility model provides an anchor rod with adjustable length, which solves the problem that the lack of length adjustment function of the anchor rod leads to the length of the anchor rod needing to be matched and customized according to the actual length of the anchor hole, resulting in the relatively limited actual use range of the anchor rod.
[0004] The technical solution for the utility model to solve the technical problems is as follows:
[0005] An anchor rod with adjustable length according to the utility model is characterized by comprising:

[0025] As Figures 1-5As shown in the figure, an anchor rod with adjustable length includes a first adjusting rod 1, a second adjusting rod 2, a high-pressure self-rotating nozzle 16, and a fixing component and a sealing component for fixing and sealing the two adjusting rods; a first stepped circle 17 is provided at the front side inside the first adjusting rod 1, a second stepped circle 18 is provided at the rear side outside the second adjusting rod 2, a slip ring 3 is provided at the rear end of the second stepped circle 18, two positioning plates 5 are symmetrically fixed at the front side, and a plurality of bayonet holes 6 are evenly formed in each positioning plate 5. The second adjusting rod 2 is slidably arranged at the first stepped circle 17 inside the first adjusting rod 1 through the slip ring 3. The high-pressure self-rotating nozzle 16 is rotationally connected and installed at the front end of the second adjusting rod 2 through a bearing, and discharge holes are formed along its circumference; there are two fixing components, which respectively correspond to the two positioning plates 5 one by one. Each fixing component includes an internal threaded plate 7 fixedly arranged at the end of the first stepped circle 17. A threaded rod 8 is threadedly connected to the internal threaded plate 7. One end of the threaded rod 8 is rotatably connected through a bearing to a clamping block 9 adapted to the bayonet hole 6. Rotating the threaded rod 8 can drive the clamping block 9 to move up and down and snap the clamping block 9 into a certain bayonet hole 6 on the positioning plate; the sealing component 10 includes an internal trapezoidal rubber gasket 4 fixedly arranged at the corner formed by the slip ring 3 and the second stepped circle 18. An expansion ring 103 is provided inside the internal trapezoidal rubber gasket 4. Two movable plates 101 corresponding to the two positioning plates 5 one by one are fixedly connected to the expansion ring 103. A plurality of inclined holes 102 used in cooperation with the respective bayonet holes 6 are evenly formed in the movable plate 101. The inclined holes 102 can be set in a trapezoidal shape with the large mouth facing the positioning plate 5. When the clamping block 9 is driven by rotating the threaded rod 8 to continue to extend from the bayonet hole 6 into the inclined hole 102, the inclined hole 102 is squeezed to drive the movable plate 101 to move. The movable plate 101 drives the expansion ring 103 to squeeze and expand the internal trapezoidal rubber gasket 4. The internal trapezoidal rubber gasket 4 is slightly deformed under extrusion and is hermetically attached to the inner wall of the first adjusting rod 1.
[0026] In this embodiment, for the convenience of adjusting the length of the anchor rod and its use, chutes 11 are respectively formed at the positions corresponding to the respective movable plates 101 on the second stepped circle 18. Sliders 12 are slidably connected inside the chutes 11. The sliders 12 are fixedly connected to the corresponding movable plates 101. A return spring 13 is fixedly connected between the sliders 12 and the chutes 11. Through the arrangement of the chutes 11 and the return spring, it is convenient for the movable plate to return when the length of the anchor rod is adjusted.
[0027] In this embodiment, a positioning rod 14 is fixedly connected to each clamping block 9. Each internal threaded plate 7 is provided with a sliding hole 15 slidably adapted to the positioning rod 14. The positioning rod 14 is inserted into the sliding hole 15. Through the arrangement of the positioning rod 14, the stability of the fixing component during use is improved.
[0028] In this embodiment, a bent portion 104 is provided at the connection position between the rear end of the movable plate 101 and the expansion ring 103, further improving the sealing effect between the two adjusting rods.
[0029] When adjusting the length, the operator drags the second adjusting rod 2 from inside the first adjusting rod 1. The second adjusting rod 2 gradually moves out from inside the first adjusting rod 1. After the length of the second adjusting rod 2 is dragged to the appropriate position, then the threaded rod 8 is rotated. The threaded rod 8 rotates and gradually drives the clamping block 9 to approach the adjacent bayonet 6, and gradually fits with the bayonet 6. Along with the continuous movement of the clamping block 9, on the basis of fitting with the bayonet 6, the clamping block 9 will also squeeze the inclined hole 102 and complete the fitting with the inclined hole 102. The inclined hole 102 is squeezed to drive the movable plate 101 to move, and the movable plate 101 drives the expansion ring 103 to squeeze and expand the inner trapezoidal rubber gasket 4. The inner trapezoidal rubber gasket 4 will slightly deform under the extrusion and complete the sealing fit with the inner wall of the first adjusting rod 1.
