Description

Technical Field

[0001] The utility model relates to the technical field of anti-skid devices, in particular to a quick anti-skid leveling device for a theodolite bracket. Background Art

[0002] The theodolite is a measuring instrument designed based on the principle of angle measurement for measuring horizontal and vertical angles. The theodolite tripod is the bottom component used to support the theodolite. When using the theodolite for engineering surveying, the tripod must first be adjusted to the appropriate angle and fixed in a stable state.

[0003] The existing patent number is CN213840325U, and the patent name is a Chinese patent for a theodolite tripod. It includes a base mounting plate, a leg connecting plate, and three legs rotatably connected to the leg connecting plate. A limit lifting assembly is fixedly connected to the center of the lower surface of the base mounting plate. The legs include two synchronously rotating rotating rods, support legs and telescopic connecting sleeves. The telescopic connecting sleeves are simultaneously mounted on the outer surfaces of the rotating rods and one end of the support legs. The support legs and the rotating rods are movably connected through the telescopic connecting sleeves. A state switching assembly is provided at the bottom end of the support legs, and a synchronous lifting device is provided in the middle area surrounded by the three legs. The plane height of the connection position of the synchronous lifting device and the support legs is slightly higher than the plane where the telescopic connecting sleeves are located. It can facilitate fine-tuning of the height and direction of the theodolite after leveling without the need to repeatedly raise and lower the legs, thereby realizing the portable movement of the theodolite tripod and preventing the problem that the theodolite mounting base is unable to be accurately leveled due to a certain degree of tilt caused by inconsistent telescopic adjustment of the three legs, but it does not interfere with the three legs being able to rotate and move independently in the lateral direction.

[0004] Although the above-mentioned existing patent can facilitate the portability of the tripod and facilitate quick and accurate leveling without repeated adjustments, since the theodolite tripod has iron pointed feet, in previous work cases, if the installation environment is a smooth ground, the theodolite tripod often slides easily and is difficult to fix due to the small contact area and low friction coefficient between the iron pointed feet and the ground, which reduces the measurement accuracy and seriously affects work efficiency. Utility Model Content

Each of the main rods is hollow and has an open end. Each of the telescopic rods slides and telescopes in the opening of the corresponding main rod. The main rod is provided with a telescopic fixing component for positioning the telescopic rod. The angle adjustment bearing is fixedly connected to each main rod. Each of the telescopic rods is fixedly provided with an end placement groove at one end away from the main rod. An anti-slip suction cup is fixedly connected to each telescopic rod.

[0008] Further specific optimization, the telescopic fixing component includes a telescopic fixing screw and a fixing knob, the telescopic fixing screw passes through and is threadedly connected to the main rod, the fixing knob is vertically fixedly connected to the end of the telescopic fixing screw extending out of the main rod, and the end of the telescopic fixing screw extending into the main rod conflicts with the telescopic rod.

[0009] Further specific optimization is that each of the telescopic rods is provided with a telescopic slide groove, and each of the main rods is fixedly provided with a telescopic slide rail, and the telescopic slide rail is slidably connected to the corresponding telescopic slide groove.

[0010] Further specific optimization is that the bottom of each end portion is fixedly connected to a groove rubber pad.

[0011] Further specific optimization is that two V-shaped tripod tip clamping pieces are symmetrically arranged in each end placement groove, and the two tripod tip clamping pieces located in the same end placement groove are vertically fixedly connected to the opposite sides with a clamping spring, and the end of the clamping spring away from the tripod tip clamping piece is fixedly connected to the side wall of the end placement groove.

[0024] For the purpose of simplicity and illustration, the principles of the embodiments are described primarily with reference to examples. In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring the understanding of these embodiments. In addition, all embodiments may be used in combination with each other.

[0025] Example:

[0026] A quick anti-slip leveling device for a theodolite stand comprises three anti-slip fixing rods 1, which are fixedly connected to the same angle adjustment bearing 2. The angle adjustment bearing 2 is provided with a locking device for locking the angles between the anti-slip fixing rods 1. Each anti-slip fixing rod 1 includes a main rod 3 and a telescopic rod 4. Each main rod 3 is hollow and has an open end. Each telescopic rod 4 slides and telescopes in the opening of the corresponding main rod 3. The main rod 3 is provided with a telescopic fixing component for positioning the telescopic rod 4. The angle adjustment bearing 2 is fixedly connected to each main rod 3. An end placement groove 5 is fixedly provided on the end of each telescopic rod 4 away from the main rod 3. An anti-slip suction cup 6 is fixedly connected to each telescopic rod 4.

[0027] The angle-adjustable bearings (2) are used to adjust the three anti-slip fixing rods (1) to different lengths and angles. The rubber suction cups secure the theodolite tripod to the smooth ground, improving its effective ground contact. Made of a high-friction rubber material, the rubber suction cups are secured to the base of the base bracket with a strong adhesive. The anti-slip pads feature a unique textured surface to increase friction with the ground and enhance the grip of the anti-slip fixing rods (1). The pointed ends of the theodolite tripod rest in the corresponding end-mounting grooves (5). The three anti-slip fixing rods (1) form a stable structure, resolving the issue of the theodolite tripod's instability on smooth surfaces.

[0028] The main rod 3 and the telescopic rod 4 are made of high-strength aluminum alloy material, which is light, corrosion-resistant and high-strength. They are light in weight and easy to carry. They are small in size and can be stored together with the original tripod, meeting the work needs of the theodolite for outdoor measurement.

[0029] The locking device is installed at the center position of the main rod 3 and the center bearing. The main rod 3 and the center opening angle are locked and unlocked by rotation or pressing. A spring and a locking pin are provided inside the locking device to ensure that the anti-slip leveling device has sufficient stability in the locked state.

[0030] The telescopic fixing component includes a telescopic fixing screw 7 and a fixing knob 8. The telescopic fixing screw 7 extends through and is threaded onto the main rod 3. The fixing knob 8 is vertically fixed to the end of the telescopic fixing screw 7 that extends out of the main rod 3. The end of the telescopic fixing screw 7 that extends into the main rod 3 contacts the telescopic rod 4. When the telescopic rod 4 is adjusted to the desired position within the main rod 3, the fixing knob 8 is rotated, driving the telescopic fixing screw 7 closer to the telescopic rod 4 until the telescopic fixing screw 7 contacts the rod body of the telescopic rod 4, thereby fixing the relative position of the main rod 3 and the telescopic rod 4. This is suitable for the installation requirements of theodolites of different specifications.

[0031] Each telescopic rod 4 is provided with a telescopic slot 9, and each main rod 3 is fixedly provided with a telescopic rail 10, which is slidably connected to the corresponding telescopic slot 9. The telescopic rail 10 moves back and forth within the corresponding telescopic slot 9, which improves the stability of the telescopic rod 4 as it slides within the main rod 3. The telescopic slot 9 and the telescopic rail 10 interlock with each other, which can improve the stability of the connection between the telescopic rod 4 and the main rod 3, thereby improving the detection stability of the theodolite after it is set up.

[0032] The bottom of each end placement groove 5 is fixedly connected with a groove rubber pad 11. The provision of the groove rubber pad 11 can increase the friction between the tip of the tripod and the bottom of the end placement groove 5, thereby improving the stability of the theodolite and improving detection efficiency.

[0033] Two V-shaped tripod tip clamping pieces 12 are symmetrically arranged within each end placement groove 5. Clamping springs 13 are vertically fixedly connected to the opposing sides of the two tripod tip clamping pieces 12 within the same end placement groove 5. The end of the clamping spring 13, facing away from the tripod tip clamping piece 12, is fixedly connected to the side wall of the end placement groove 5. When the tip of the theodolite tripod is placed in the end placement groove 5, the tip presses against the tripod tip clamping piece 12, pushing the tripod tip clamping piece 12 against the clamping spring 13. Under the action of the elastic force of the clamping spring 13, the two tripod tip clamping pieces 12 clamp the tripod tip in a limited position, meeting the placement requirements of theodolites of different specifications and improving the stability of the placement of the theodolite.

[0034] One end of each telescopic fixing screw 7 extending into the main rod 3 is fixedly connected to a telescopic anti-slip pad 14. Turning the fixing knob 8 drives the end of the telescopic fixing screw 7 close to the telescopic rod 4 and contacts the rod body of the telescopic rod 4. The telescopic anti-slip pad 14 can increase the friction between the telescopic fixing screw 7 and the telescopic rod 4, improve the stability of the fixation between the telescopic rod 4 and the main rod 3, and prevent the telescopic fixing screw 7 from leaving a dent on the telescopic rod 4, thereby extending the service life of the telescopic rod 4.

[0035] The invention discloses a quick anti-skid leveling device for a theodolite stand. When in use, the telescopic rod 4 is first telescopically slid in the main rod 3, and then the position of the telescopic rod 4 in the main rod 3 is fixed by the fixing knob 8 and the telescopic fixing screw 7. Then, the angle between the three main rods 3 is adjusted by the angle adjustment bearing 2, and a stable structure is formed between the three anti-skid fixing rods 1. Then, the anti-skid suction cup 6 is adsorbed on the ground to fix the three anti-skid fixing rods 1. Then, the three prongs of the erected theodolite tripod are placed in the end placement grooves 5 at the ends of the corresponding three telescopic rods 4. The clamping spring 13 cooperates with the tripod prong clamping piece 12 to clamp and limit the prongs, thereby ensuring the stability of the tripod prongs in the end placement grooves 5. The original contact mode between the theodolite tripod and the ground is changed to improve the effective fixation to the ground, significantly improve the overall stability, meet different erection requirements, and improve the working efficiency of the theodolite in special environments.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
