[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0027] This application discloses a level instrument reinforcement and stabilization device.
[0028] refer to Figure 1 and Figure 2 The leveling instrument's stabilizing device includes a center rod 7, an adjusting cylinder 1, a fine-tuning sleeve 2, and a support rod 3. The center rod 7 is fixed to the lower surface of the tripod's top base, and its outer wall has multiple vertically distributed positioning ring grooves 71. The adjusting cylinder 1 is slidably connected to the center rod 7. The adjusting cylinder 1 is equipped with a positioning component 5 to fix its position on the center rod 7, and an unlocking component 6 to release the fixed position of the adjusting cylinder 1. The fine-tuning sleeve 2 is installed on the adjusting cylinder 1 and can be finely slid relative to the adjusting cylinder 1. The support rod 3 is rotatably connected to the fine-tuning sleeve 2, and the support rod 3 is equipped with a fixing component 4 to fix it to the tripod's legs.
[0029] After the tripod is extended, the position of the adjusting cylinder 1 is released by the unlocking component 6, and then the position of the adjusting cylinder 1 is fixed by the positioning component 5. By rotating the support rod 3, the support rod 3 is fixed to the tripod legs by the fixing component 4, thereby improving the stability of the tripod after it is extended.
[0030] refer to Figure 2 and Figure 3 The positioning component 5 includes a positioning plate 51 and a positioning spring 52. A positioning groove 11 is provided on the circumferential outer wall of the adjusting cylinder 1. The positioning plate 51 is slidably connected in the positioning groove 11. One end of the positioning spring 52 is fixedly connected to the inner wall of the positioning groove 11, and the other end is fixedly connected to the positioning plate 51. The positioning spring 52 makes the positioning plate 51 press against the positioning ring groove 71.
[0031] The unlocking assembly 6 includes an unlocking plate 61, an anti-detachment plate 62, and an unlocking spring 63. Unlocking grooves 12, communicating with the outside, are formed on the inner walls of both sides of the positioning groove 11. Anti-detachment grooves 13 are formed on the inner walls of the unlocking grooves 12. The portion of the positioning plate 51 directly opposite the anti-detachment groove 13 is inclined and transitioned. The unlocking plate 61 is slidably connected within the unlocking groove 12, and the anti-detachment plate 62 is fixed to the circumferential outer wall of the unlocking plate 61 and located within the anti-detachment groove 13. The unlocking spring 63 is located within the anti-detachment groove 13, with one end fixedly connected to the inner wall of the anti-detachment groove 13 and the other end fixedly connected to the anti-detachment plate 62. When the unlocking spring 63 is in its natural state, the unlocking plate 61 extends out of the unlocking groove 12 and is not located within the positioning groove 11. The unlocking plate 61 can slide to the portion abutting against the inclined surface of the positioning plate 51, causing the positioning plate 51 to be fully positioned within the positioning groove 11.
[0032] When the position of the adjusting cylinder 1 needs to be adjusted, press the unlocking plate 61. The unlocking plate 61 abuts against the positioning plate 51 and drives the positioning plate 51 to slide into the positioning groove 11, thereby separating it from the positioning ring groove 71. Then, the position of the adjusting cylinder 1 can be adjusted. After releasing the unlocking plate 61, the positioning plate 51 resets and re-locks into the corresponding positioning ring groove 71, re-fixing the position of the adjusting cylinder 1, thus improving the efficiency of the position adjustment and the stability of the position fixation.
[0033] refer to Figure 2 The fine-tuning sleeve 2 includes an adjusting ring 21 and a knob 22. The adjusting ring 21 is slidably connected to the top of the outer wall of the adjusting cylinder 1. There are three support rods 3, which are rotatably connected to the adjusting ring 21. The knob 22 is rotatably connected to the bottom end of the adjusting ring 21 and threadedly connected to the outer wall of the adjusting cylinder 1. A mounting frame 211 is installed below the rotation axis of the support rods 3 on the adjusting ring 21. After the support rods 3 are rotated to the downward vertical position, they will be locked and fixed to the inner wall of the mounting frame 211.
[0034] When fine-tuning of the position of the support rod 3 is required, rotating the knob 22 causes the adjusting ring 21 to slide vertically, improving the accuracy and stability of the support rod 3's position adjustment. The support rod 3 can also be retracted by rotating it and locking it into the mounting frame 211.
[0035] refer to Figure 4 The fixing component 4 includes a hook plate 41 and a sliding rod 42. A fixing groove 8 is provided on the inner side of the tripod legs. A sliding hole 31 is provided at the end of the support rod 3 away from its own rotation axis, and the sliding rod 42 is slidably connected within the sliding hole 31. A sliding spring 32 is fixedly installed on the inner wall of the sliding hole 31, and the other end of the sliding spring 32 is fixedly connected to the sliding rod 42, so that the end of the sliding rod 42 extends out of the sliding hole 31. A fixing block 33 is fixedly installed on the side wall of the support rod 3, and the hook plate 41 is rotatably connected to the fixing block 33. After the hook plate 41 rotates, it can press against the side of the tripod legs away from the support rod 3.
[0036] After the sliding rod 42 is compressed, it springs into the fixing groove 8, thereby fixing the position of the support rod 3. Then, the hook plate 41 is rotated to tighten the hook plate 41 onto the tripod legs, thereby improving the stability of the support rod position and also improving the stability of the tripod legs' opening angle.
[0037] The implementation principle of the leveling instrument reinforcement and stabilization device in this application embodiment is as follows: After the tripod legs are extended, pressing the unlocking plate 61 causes the positioning plate 51 to retract, and then the sliding adjustment cylinder 1 is slid to a suitable distance before releasing the unlocking plate 61. After fine-tuning by rotating the knob 22, rotating the support rod 3 causes the sliding rod 42 to be positioned and tightened within the fixing groove 8. Subsequently, rotating the hook plate 41 tightens the tripod legs, thereby stabilizing the tripod legs. This effectively improves the stability of the tripod legs after they are extended.
[0038] 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.
