Description

Technical Field

[0001] This utility model relates to the field of total station support technology, specifically a total station anti-slip support. Background Technology

[0002] A total station support is a specialized device for supporting and securing a total station. It mainly consists of a tripod and a base. The tripod is usually made of lightweight metal (such as aluminum alloy) or carbon fiber and has adjustable leg length and telescopic function to adapt to different terrains and observation height requirements. The base connects the total station to the tripod and is equipped with a leveling screw and an optical centering device to ensure that the instrument can be quickly leveled and centered. The support needs to be highly stable, shock-resistant, and corrosion-resistant. Portability should also be considered when working in the field.

[0003] Total station supports can improve measurement efficiency and are widely used in engineering surveying, topographic mapping, and other fields. However, they still have some problems: 1) Traditional total station supports use sharp structures inserted into the soil for stable support at the contact points with the ground. However, when applied to rocky or steep, hard terrain, the legs cannot be inserted into the ground and therefore cannot provide stable support; 2) For total station supports that use sharp legs for support, the sharp parts can easily scratch workers or vehicles during handling and transportation, posing certain safety hazards. Therefore, in view of the above situation, there is an urgent need to develop a total station anti-slip support to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this utility model is to provide a total station anti-slip bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a total station anti-slip bracket, comprising a hinge seat, a support shaft, and a telescopic shaft, wherein multiple support shafts are hinged to the bottom edge of the hinge seat, the telescopic shaft is slidably mounted on the support shaft, and a retractable support mechanism is installed at the bottom of the telescopic shaft;

[0006] The retractable support mechanism includes a support leg, an anti-slip sleeve, a foot pedal, a slider, and a tension spring a. The bottom end of the telescopic shaft has a mounting groove. The tension spring a and the slider are movably installed in the mounting groove in sequence. The foot pedal is fitted on the bottom end of the telescopic shaft. The anti-slip sleeve is detachably installed on the lower surface of the foot pedal. The support leg passes through the foot pedal and the anti-slip sleeve in sequence and is detachably connected to the bottom end of the slider. A locking component for limiting the slider is fixed on the outer wall of the telescopic shaft. A limiting shaft adapted to the locking component is detachably installed on the side wall of the slider.

[0007] Preferably, the bottom of the anti-slip sleeve has a through "H"-shaped groove, and the middle position of the anti-slip sleeve forms a flip-up part. Both the anti-slip sleeve and the flip-up part are made of flexible rubber material. The flip-up part can rotate 90 degrees around the connection position with the anti-slip sleeve. Specifically, the anti-slip sleeve can directly contact the ground when the outrigger is retracted, increasing friction and providing stable support. When the outrigger is extended, it will force the flip-up part to rotate outward to avoid obstructing the outrigger from extending.

[0008] Preferably, the locking assembly includes a housing, a locking pawl, a reset handle, a tension spring b, and an unlocking handle. The housing is fixed to the outer wall of the bottom end of the telescopic shaft. The locking pawl is rotatably installed inside the housing. The reset handle is fixed to the outer wall of the rotation center of the locking pawl. The tension spring b is installed between the reset handle and the inner wall of the housing. The unlocking handle is fixed to the outer wall of the locking pawl. Specifically, the tension spring b can drive the locking pawl to rotate counterclockwise around the rotation connection position to lock the limiting shaft.

[0009] Preferably, the outer wall of the housing has a through groove, and the end of the unlocking handle passes through the through groove. Specifically, by moving the unlocking handle, the locking pawl can be disengaged from the limiting shaft to achieve the unlocking effect.

[0010] Preferably, the bottom outer wall of the telescopic shaft is provided with a groove, and the limiting shaft is slidably disposed in the groove. Specifically, the groove can cooperate with the limiting shaft to limit the range of motion of the slider.

[0011] Preferably, the limiting shaft and the locking pawl are adapted to each other. Specifically, when the slider descends to the bottom, it will cause the support leg to extend out from the telescopic shaft, and at the same time, the limiting shaft will trigger the locking pawl along the slide groove and lock it.

[0012] Compared with the prior art, this utility model provides a total station anti-slip bracket, which has the following beneficial effects:

[0013] It adopts a retractable support component that can be switched according to terrain features. When used on hard paved surfaces, it forms a large contact surface through elastic anti-slip sleeves. When facing soft mud or gravel roads, it can use tapered reinforced feet to achieve precise positioning and significantly improve support stability. This dual-mode switching mechanism allows the equipment to adapt to a variety of complex terrains, from concrete bases to lawns and sandy areas, effectively expanding the application range of the equipment in complex working conditions.

[0014] In terms of safety protection, the tapered legs can be completely retracted into the high-strength aluminum alloy telescopic shaft. This design not only avoids accidental damage to personnel and transport vehicles during transportation or handling, but also completely eliminates the safety hazards caused by exposed sharp parts through the hidden storage solution. Users can quickly switch the support mode with just a simple rotation operation, which greatly improves the efficiency of equipment deployment and operational safety. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example:

[0026] Please see Figures 1-6 This utility model provides a technical solution: a total station anti-slip bracket, including a hinge seat 10, a support shaft 20 and a telescopic shaft 30, multiple support shafts 20 are hinged to the bottom edge of the hinge seat 10, the telescopic shaft 30 is slidably mounted on the support shaft 20, and a retractable support mechanism 40 is installed at the bottom of the telescopic shaft 30.

[0027] The retractable support mechanism 40 includes a support leg 410, an anti-slip sleeve 420, a foot pedal 430, a slider 440, and a tension spring a450. The bottom end of the telescopic shaft 30 is provided with an installation groove. The tension spring a450 and the slider 440 are movably installed in the installation groove in sequence. The foot pedal 430 is sleeved on the bottom end of the telescopic shaft 30. The anti-slip sleeve 420 is detachably installed on the lower surface of the foot pedal 430. The support leg 410 passes through the foot pedal 430 and the anti-slip sleeve 420 in sequence and is detachably connected to the bottom end of the slider 440. The outer wall of the telescopic shaft 30 is fixed with a locking component 460 for limiting the slider 440. The side wall of the slider 440 is detachably installed with a limiting shaft 441 adapted to the locking component 460.

[0028] Preferably, the bottom of the anti-slip sleeve 420 is provided with a through "H"-shaped groove, and the middle position of the anti-slip sleeve 420 forms a flipping part 421. Both the anti-slip sleeve 420 and the flipping part 421 are made of flexible rubber material. The flipping part 421 can be flipped 90 degrees around the connection position with the anti-slip sleeve 420. Specifically, the anti-slip sleeve 420 can directly contact the ground when the support leg 410 is retracted, increasing friction and providing stable support. When the support leg 410 is ejected, it will force the flipping part 421 to flip outward to avoid obstructing the ejection of the support leg 410.

[0029] Preferably, the locking assembly 460 includes a housing 461, a locking pawl 462, a reset handle 463, a tension spring b464, and an unlocking handle 465. The housing 461 is fixed to the outer wall of the bottom end of the telescopic shaft 30. The locking pawl 462 is rotatably mounted inside the housing 461. The reset handle 463 is fixed to the outer wall of the rotation center of the locking pawl 462. The tension spring b464 is installed between the reset handle 463 and the inner wall of the housing 461. The unlocking handle 465 is fixed to the outer wall of the locking pawl 462. Specifically, the tension spring b464 can drive the locking pawl 462 to rotate counterclockwise around the rotation connection position, thereby locking the limiting shaft 441.

[0030] Preferably, the outer wall of the housing 461 has a through groove, and the end of the unlocking handle 465 passes through the through groove. Specifically, by moving the unlocking handle 465, the locking pawl 462 can be disengaged from the limiting shaft 441 to achieve the unlocking effect.

[0031] Preferably, a groove 310 is provided on the bottom outer wall of the telescopic shaft 30, and the limiting shaft 441 is slidably disposed in the groove 310. Specifically, the groove 310 can cooperate with the limiting shaft 441 to limit the range of motion of the slider 440.

[0032] Preferably, the limiting shaft 441 is adapted to the locking claw 462. Specifically, when the slider 440 descends to the bottom, it will cause the support leg 410 to extend out from the telescopic shaft 30. At the same time, the limiting shaft 441 will trigger the locking claw 462 along the slide groove 310 and lock it.

[0033] Working principle: When in use, simply unfold the support shaft 20 and place it on the ground. Adjust the length of the telescopic shaft 30 extending from the support shaft 20 according to the flatness of the ground and usage requirements, thus keeping the upper surface of the hinge base 10 nearly horizontal. Finally, install the total station on the hinge base 10. Switch the operating state of the retractable support mechanism 40 according to the ground type. When using on soft ground, pull the limiting shaft 441 downwards until it contacts and locks with the locking component 460. At this time, the slider 440 drives the foot 410 to extend from the telescopic shaft 30. During the extension process, the flipping part 421 of the anti-slip sleeve 420 flips outwards, at which point the sharper part of the foot 410 fully extends to the bottom of the telescopic shaft 30. The operator, with the help of the foot pedal 430, applies downward pressure to the foot 410, causing the foot 410 to insert into the soft ground, achieving the support effect. When used on hard surfaces or steep slopes, the locking assembly 460 releases the lock on the limiting shaft 441. Under the action of the tension spring a450, the slider 440 and the support leg 410 are reset, retracting into the retraction shaft 30. At this time, the flipping part 421 resets due to its own material properties, and the anti-slip sleeve 420 is at the bottom. The anti-slip sleeve 420 contacts the hard surface or steep slope, increasing the contact surface and friction, and providing a stable support effect. It should be noted that when the limiting shaft 441 contacts the locking pawl 462, due to the shape characteristics of the locking pawl 462, it will force the locking pawl 462 to rotate clockwise by a certain angle until the limiting shaft 441 exceeds the locking pawl 462. Then, the locking pawl 462 locks the limiting shaft 441. When unlocking is required, the unlocking handle 465 is turned clockwise, causing the locking pawl 462 to disengage from the limiting shaft 441, thus achieving the unlocking effect.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
