[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the present invention discloses a folding and telescopic device, including a mounting frame 1, a motor 2 is detachably connected to the top of the mounting frame 1, a power assembly 3 is passed through the output end of the motor 2, the power assembly 3 is detachably connected to the mounting frame 1, the power assembly 3 includes a housing 301, the output end of the motor 2 passes through the housing 301, a driving wheel 302 is fixedly connected to the output end of the motor 2, and two ends of the driving wheel 302 are respectively meshed and connected with driven wheels 303, the driving wheel 302 and the two driven wheels 303 are both located inside the housing 301, and one of the driven wheels 303 is connected to the housing 301. The driven wheel 303 is threadedly connected with a first driven component 4, and the other driven wheel 303 is detachably connected with a second driven component 5. The first driven component 4 includes a first worm 401, which passes through the driven wheel 303. The first worm 401 is threadedly connected to the driven wheel 303. The end of the first worm 401 away from the driven wheel 303 is meshedly connected with a first worm wheel 402. The first worm wheel 402 is a trapezoidal worm wheel. The first worm 401 is sleeved with a disc spring 16, and the disc spring 16 is fixedly connected to the first worm 401. The disc spring 16 is in contact with the driven wheel 303, a fixed shaft 403 is embedded in the middle of the first worm wheel 402 and is rotatably connected, a folded worm wheel pad 404 is fixedly connected to the side of the first worm wheel close to the fixed shaft, the second driven assembly 5 includes a second worm 501, the second worm 501 is detachably connected to the driven wheel 303, one end of the second worm 501 away from the driven wheel 303 is meshedly connected to the second worm wheel 502, a tape shaft 503 is embedded in the middle of the second worm wheel 502 and is fixedly connected, the fixed shaft 403 passes through the tape shaft 503, The fixed shaft 403 is rotationally connected with the tape winding shaft 503, the folding worm gear pad 404 is fixedly connected with a bamboo joint seat 6, the bamboo joint seat 6 is rotationally connected with the tape winding shaft 503, a lifting belt 7 is wound around the tape winding shaft 503, an outer bamboo joint 8 is fixedly connected to the bamboo joint seat 6, an inner bamboo joint 11 is sleeved in the outer bamboo joint 8, the outer bamboo joint 8 is slidingly connected with the inner bamboo joint 11, the end of the inner bamboo joint 11 away from the outer bamboo joint 8 is fixedly connected with a pan-tilt seat 9, the bottom end of the pan-tilt seat 9 is detachably connected with a pan-tilt 10, and the lifting belt 7 is detachably connected to the pan-tilt seat 9.

[0020] Among them, the present invention utilizes a worm gear transmission mechanism, combined with the adaptive adjustment function of the disc spring 16, to effectively improve the stability and reliability of the transmission, reduce the transmission error caused by vibration or load change, and ensure the stable operation of the device in a complex environment. Through a multi-directional folding design (including horizontal rotation and vertical lifting), the device can flexibly adjust the shooting angle and height of the pan-tilt head 10 and the camera equipment, greatly broadening the shooting range and meeting the monitoring needs in different scenes. The use of a sturdy bamboo seat 6 and a winding shaft 503 structure, combined with a high-strength lifting belt 7, ensures the stability and safety of the pan-tilt head 10 and the camera equipment during the lifting process, and can withstand a large load without being easily deformed or damaged.

[0021] like Figure 4 As shown, the belt winding shaft 503 includes a main body 5031, the main body 5031 is fixedly connected to the second worm gear 502, the fixed shaft 403 passes through the main body 5031, the main body 5031 is rotatably connected to the fixed shaft 403, the main body 5031 is rotatably connected to the bamboo node seat 6, and one end of the main body 5031 away from the second worm gear 502 is fixedly connected to a limiting guide wheel 5032, and the lifting belt 7 is wound around the limiting guide wheel 5032.

[0022] By fixing the body 5031 with the second worm gear 502, the accuracy and stability of power transmission are ensured. At the same time, the rotation connection design of the body 5031 with the fixed shaft and the bamboo seat 6 enables the winding shaft 503 to maintain stable operation when bearing load, reducing the transmission resistance caused by friction or vibration. The limiting guide wheel 5032 is fixed on the body 5031, providing an accurate guide path for the lifting belt 7, effectively preventing the lifting belt 7 from deflecting or getting stuck during the winding or unwinding process, thereby ensuring the stability and reliability of the lifting action. As a wearing part, the limiting guide wheel 5032 is independently designed so that it can be easily replaced when needed, without the need to disassemble the winding shaft 503 as a whole, thereby reducing maintenance costs. At the same time, the limiting guide wheel 5032 and the body 5031 made of high-quality materials enhance the durability of the entire winding shaft 503 and extend the service life.

[0023] Preferably, the lifting belt 7 is a cloth belt.

[0024] Among them, a cloth belt is used as the lifting belt 7. Compared with metal or hard materials, the cloth belt has a lighter weight, which helps to reduce the weight of the entire folding and telescopic device and improve its portability and flexibility. At the same time, the cloth belt also has good wear resistance and corrosion resistance, can maintain stable performance in a variety of environments, and prolong the service life. The cloth belt has good flexibility and elasticity, which makes the winding and releasing process of the lifting belt 7 smoother, reducing the problem of jamming or breaking caused by too hard materials; in addition, the adjustment range of the cloth belt is wider, which can meet the adjustment requirements of different heights and angles, and improves the applicability and flexibility of the device. As a common material, the procurement cost of the cloth belt is relatively low, which helps to reduce the production cost of the entire folding and telescopic device; at the same time, since the cloth belt is easy to maintain and replace, it also reduces the subsequent maintenance cost and improves the cost performance of the product. As a recyclable material, the use of the cloth belt is in line with the concept of environmental protection; after the device reaches the end of its service life, the cloth belt can be recycled and reused to reduce waste.

[0025] Furthermore, a guide roller shaft 12 is fixedly connected inside the bamboo joint seat 6 , a cloth belt guide roller 13 is fixedly connected to the guide roller shaft 12 , and the cloth belt guide roller 13 is in contact with the lifting belt 7 .

[0026] The guide roller shaft 12 and the cloth belt guide roller 13 are added inside the bamboo joint seat 6, which can effectively guide the running direction of the lifting cloth belt, reduce the deviation and friction of the cloth belt during the movement, and thus improve the stability and reliability of the cloth belt operation. The addition of the guide roller shaft 12 and the cloth belt guide roller 13 further enhances the structural strength of the bamboo joint seat 6 and its connecting parts, making the entire folding and telescopic device more stable when bearing loads and less prone to deformation or damage. By reasonably guiding the running path of the cloth belt, the direct contact and wear between the cloth belt and the surrounding parts are reduced, thereby extending the service life of the cloth belt and reducing maintenance costs.

[0027] Optionally, a limit stopper 14 is detachably connected to a middle portion of a side of the mounting frame 1 away from the housing 301 , and the limit stopper 14 is located outside the mounting frame 1 .

[0028] The limit stopper 14 is located outside the mounting frame 1. When the device is in a folded state and the outer bamboo joint 8 rotates to a vertical state, the bamboo joint seat 6 is blocked by the mounting frame 1 and the limit stopper 14 and cannot continue to rotate, thereby improving the safety performance of the entire device.

[0029] Preferably, a side of the first worm gear 402 away from the folding worm gear pad 404 and a side of the second worm gear 502 away from the body 5031 are rotatably connected to a worm gear cover 15 , respectively, and the worm gear cover 15 is fixedly connected to the mounting frame 1 .

[0030] The worm gear cover 15, as a fixed component, can effectively prevent the worm gear from shaking or deflecting due to uneven force or external factors during the transmission process, thereby ensuring the accuracy and stability of the transmission. The worm gear cover 15 forms an additional protective barrier for the worm gear, reducing the possibility of external contaminants such as dust and impurities entering the worm gear, reducing the risk of wear and failure, and extending the service life of the device.

[0031] Preferably, the motor 2 is a servo motor 2 .

[0032] The servo motor 2 ensures the stability and accuracy of the device during operation with its high precision, high response speed and high reliability. Specifically, the servo motor 2 can accurately control the speed and torque, making the device move more smoothly and smoothly during the extension and folding process, reducing the damage to the device caused by mechanical vibration or impact.

[0033] like Figure 7 As shown, the present invention also discloses a method for using the folding and telescopic device, the method adopts the folding and telescopic device, and the method comprises the following steps: S1, the bamboo joint is in a fully contracted and horizontal state in its initial state; the motor 2 is started, and the motor 2 drives the rotation of the driving wheel 302, and the driving wheel 302 drives the driven wheels 303 at both ends to rotate, wherein one of the driven wheels 303 drives the first worm 401 to rotate, and the other driven wheel 303 drives the second worm 501 to rotate.

[0034] S2, the first worm 401 drives the first worm wheel 402 to rotate, and the first worm wheel 402 drives the folding worm wheel pad 404 to rotate and then drives the bamboo joint seat 6 to rotate.

[0035] S3, the second worm 501 drives the second worm wheel 502 to rotate, the second worm wheel 502 drives the take-up shaft 503 to rotate, the take-up shaft 503 drives the movement of the lifting belt 7, and the lifting belt 7 drives the inner bamboo node 11 to move up and down inside the outer bamboo node 8, thereby driving the contraction of the pan-tilt seat 9 and the pan-tilt 10.

[0036] S4, when the bamboo section changes from a horizontal state to a vertical state, since the first driven wheel 303 is tightly connected to the first worm 401 through the disc spring 16, the disc spring 16 is at the maximum compression amount at this time, and the driven wheel 303 can drive the first worm 401 to rotate through friction, and then drive the outer bamboo section 8 to rotate. When the outer bamboo section 8 rotates to a vertical state, the bamboo section seat 6 is blocked by the mounting frame 1 and cannot continue to rotate. However, when the motor 2 continues to rotate, the friction force between the disc spring 16 and the driven wheel 303 will not be sufficient to continue to maintain the rigid connection between the driven wheel 303 and the first worm 401, causing the driven wheel 303 to disengage from the disc spring 16 and move forward along the trapezoidal screw. At this time, the driven wheel 303 no longer provides driving force to the first worm 401.

[0037] S5, at this time, the driven wheel 303 drives the second worm 501 to move, driving the belt reel 503 to rotate 90 degrees, and the bamboo section does not extend or retract, and the bamboo section rotates 90 degrees, which cancels each other out.

[0038] S6, when the rotation continues from the vertical state, the bamboo node begins to elongate.

[0039] S7, when the motor 2 rotates in the reverse direction, the outer bamboo nodes 8 in S4-S6 move in the opposite direction.

[0040] Through the above steps, the method for using the folding and telescopic device of the present invention can effectively adjust the shooting field of view of equipment such as inspection robots, thereby improving work efficiency and shooting quality.

[0041] Furthermore, the S3 specifically includes: S301, the second worm 501 drives the second worm gear 502 to rotate, and the second worm gear 502 drives the body 5031 of the tape take-up shaft 503 to rotate.

[0042] S302, the main body 5031 drives the limiting guide wheel 5032 to rotate, thereby driving the movement of the lifting belt 7, and the lifting belt 7 drives the inner bamboo section 11 to move up and down inside the outer bamboo section 8, thereby driving the pan-tilt seat 9 and the pan-tilt 10 to retract.

[0043] The lifting belt 7 is driven to move by the limiting guide wheel 5032, which provides a precise guide path for the lifting belt 7, effectively preventing the lifting belt 7 from deflecting or getting stuck during the winding or unwinding process, thereby ensuring the stability and reliability of the lifting action.

[0044] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0045] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
