The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1

[0042] Reference Figure 1-2, which is the first embodiment of the present invention, and provides a multi-scenario application handheld inspection device, including a shooting component 100, which includes a hollow gripping rod 101 and a posture adjustment component 102 installed on the top of the hollow gripping rod 101, and a camera body 103 is detachably installed on the top of the posture adjustment component 102; the posture adjustment component 102 includes a first hollow adjustment rod 102a, a second hollow adjustment rod 102b and two rotating mechanisms 102c, and both ends of the first hollow adjustment rod 102a are movably connected to the hollow gripping rod 101 and the second hollow adjustment rod 102b through the rotating mechanism 102c, so as to change the camera The shooting posture of the main body 103; the driving component 200, which includes a rotating part 201 arranged on the hollow gripping rod 101, and two transmission belts 202 are sleeved on the rotating part 201, and the two transmission belts 202 are respectively connected with two rotating mechanisms 102c, and the rotating part 201 can drive the corresponding transmission belt 202 to rotate to control the corresponding rotating mechanism 102c to rotate; the gap locking component 300, which includes a magnetic ring 301 and a damping mechanism 302 installed on the rotating part 201, and the magnetic ring 301 is arranged on the rotating part 201 to drive the damping mechanism 302 to increase the rotation damping of one of the transmission belts 202.

[0043] The posture adjustment component 102 can realize the multi-angle adjustment of the camera body 103 to meet the shooting requirements in different scenes; the camera body 103 and the posture adjustment component 102 are detachable, which is convenient for carrying and replacing different cameras; the combination of the first hollow adjustment rod 102a and the second hollow adjustment rod 102b, as well as the design of the two rotating mechanisms 102c, can ensure stability during the adjustment process; the operation is simple, and the user can easily control the two transmission belts 202 through the rotating part 201, and then adjust the shooting angle; the combination of the magnetic ring 301 and the damping mechanism 302 can increase the rotation resistance of the transmission belt 202 when necessary, thereby preventing accidental movement and improving shooting stability;

[0044] Reference Figure 2-5The rotating mechanism 102c includes a rotating base 102c-1 and a rotating shaft 102c-2 rotatably arranged inside the rotating base 102c-1. A damping plate is fixed between the rotating base 102c-1 and the rotating shaft 102c-2. A driven gear 102c-3 is fixed at the axis of the rotating shaft 102c-2. The rotating part 201 includes a rotating rod 201a movably arranged on the hollow gripping rod 101. The rotating rod 201a is symmetrically provided with a first transmission gear 201b and a second transmission gear 201c. The transmission belt 202 sleeves and connects the first transmission gear 201b and the second transmission gear 201c with the two driven gears 102c-3 respectively, so as to drive the driven gear 102c-3 to rotate to a preset angle. A driving toothed disc 201d is provided between the first transmission gear 201b and the second transmission gear 201c. The driving toothed disc 201d is fixed to the rotating rod 201a. The first transmission gear 201b, the second transmission gear 201c and the driving toothed disc 201d have mutually engaging grooves on their opposite surfaces. When the driving toothed disc 201d is in contact with the first transmission gear 201b, the first transmission gear 201b is driven to rotate. When the driving toothed disc 201d is in contact with the second transmission gear 201c, the second transmission gear 201c is driven to rotate.

[0045] In this embodiment, when in use, the camera body 103 is fixed to the support platform of the second hollow adjustment rod 102b by bolts. Then, the user can observe the equipment installed at a higher position by holding the hollow grip rod 101, which is convenient to use.

[0046] When it is necessary to observe equipment in narrow corners or confined spaces, the user can extend the posture adjustment component 102 into the area to be observed. Then, the staff can adjust the posture of the posture adjustment component 102 according to the distribution of equipment in the space, so that the camera body 103 can better observe the equipment.

[0047] Specifically, the staff can rotate the rotating rod 201a according to the actual situation, and the rotating rod 201a drives the fixedly connected driving toothed disc 201d to rotate. When it is necessary to adjust the angle of the first hollow adjustment rod 102a, the user can pull the rotating rod 201a, and the rotating rod 201a drives the driving toothed disc 201d to fit with the first transmission gear 201b to achieve power transmission. When the first transmission gear 201b rotates, the driven gear 102c-3 is driven to rotate through the meshing transmission belt 202, and the driven gear 102c-3 drives the first hollow adjustment rod 102a to rotate through the rotating shaft 102c-2, thereby adjusting the observation posture of the camera body 103 for the first time;

[0048] When the first hollow adjustment rod 102a is blocked during the adjustment process, the staff can push the driving gear plate 201d to fit the second transmission gear 201c to realize power transmission. At the same time, the power of the first transmission gear 201b is cut off. When the second transmission gear 201c rotates, the corresponding meshing transmission belt 202 drives the driven gear 102c-3 at the second hollow adjustment rod 102b to rotate, thereby performing a secondary adjustment on the observation posture of the camera body 103, which is more flexible to use.

[0049] By adopting mechanical drive, when it is necessary to inspect equipment in special areas such as oil pump rooms and hydrogen production stations, general electronic products cannot be carried. The device has a fireproof and explosion-proof structure and can be used safely in the above areas.

[0050] In addition, the length of the shooting component 100 is preferably 1-2.1 meters to avoid the shooting component 100 being too long, which would affect its own stability during use; the camera body 103 is made of high-strength explosion-proof material, which is impact-resistant, anti-static, fire-proof, explosion-proof, dust-proof, and waterproof, and can be flexibly used in various scenarios, and the camera body 103 has a built-in wireless module, which can observe the camera image in real time, making it convenient for patrol personnel to conduct on-site data analysis; the camera body 103 can use an electric support frame or a manual support frame as needed, which is convenient for adjusting the camera angle of the camera body 103; the hollow grip rod 101 is made of epoxy resin insulating material to prevent people from electric shock.

[0051] Example 2

[0052] Reference Figure 2 and Figure 6-7 , which is the second embodiment of the present invention. Different from the previous embodiment, two magnetic rings 301 are provided, and the magnetic rings 301 are rotatably provided on the rotating rod 201a, and the first transmission gear 201b and the second transmission gear 201c are both located between the two magnetic rings 301. The damping mechanism 302 includes a fixed ring 302a, and the first transmission gear 201b and the second transmission gear 201c are both provided with fixed rings 302a on the surfaces opposite to the magnetic rings 301, and the fixed ring 302a is fixed to the inner wall of the hollow gripping rod 101. A plurality of sliding blocks 302b are slidably provided inside the fixed ring 302a, and the sliding blocks 302b are used to apply damping to the gap between the first transmission gear 201b and the second transmission gear 201c, and a compression spring 302c is fixedly connected between the sliding block 302b and the fixed ring 302a; wherein, a magnetic sheet is fixed on the sliding block 302b, and the magnetic ring 301 corresponds to the magnetic sheet, and the magnetic ring 301 and the magnetic sheet have opposite magnetic properties.

[0053] It can be seen from Example 1 that after the first hollow adjustment rod 102a or the second hollow adjustment rod 102b is adjusted, if it cannot restrict itself, then in subsequent use, the first hollow adjustment rod 102a or the second hollow adjustment rod 102b will rotate, resulting in a change in angle, affecting shooting.

[0054] To solve the above problem, a gap locking assembly 300 is added to increase the damping of the first transmission gear 201b or the second transmission gear 201c, thereby increasing the rotational friction of the first hollow adjustment rod 102a or the second hollow adjustment rod 102b to improve the shooting stability.

[0055] Specifically, when the staff first adjusts the first hollow adjustment rod 102a through the first transmission gear 201b and needs to adjust the second hollow adjustment rod 102b again, the staff will synchronously drive the magnetic ring 301 when pushing the rotating rod 201a to slide. At this time, the magnetic ring 301 is in contact with the damping mechanism 302 on the driving gear plate 201d, and the sliding block 302b will drive multiple sliding blocks 302b to approach the first transmission gear 201b under the action of magnetic repulsion, thereby increasing the rotational damping of the driving gear plate 201d, thereby achieving the locking of the angle of the first hollow adjustment rod 102a and improving the stability during shooting. Similarly, when the first transmission gear 201b is adjusted, the second transmission gear 201c is also in a locked state under the action of the damping mechanism 302.

[0056] A rubber layer is fixed to the contact end of the compression spring 302c and the first transmission gear 201b or the second transmission gear 201c, thereby increasing the contact friction between the two.

[0057] Example 3

[0058] Reference Figure 2 , Figure 4 and Figure 8, which is the third embodiment of the present invention, and this embodiment further provides a handheld inspection device for multi-scenario applications. A control knob 401 is provided above the rotating rod 201a, and the control knob 401 is rotatably set on the hollow gripping rod 101. The outer side of the control knob 401 is threadedly connected to a piston sleeve 402, and a piston cylinder 403 is movably sleeved on the outer side of the piston sleeve 402. The inside of the piston cylinder 403 is filled with a medium, and the medium flows under the squeeze of the piston cylinder 403. A plurality of hoses 404 are connected to the piston cylinder 403, and the ends of the hoses 404 away from the piston cylinder 403 are all connected to a telescopic cylinder 405, and the telescopic cylinder 405 is located on the rotating base 102c-1, and an insert block 406 is slidably provided inside the telescopic cylinder 405, and a reset spring can be fixed between the insert block 406 and the telescopic cylinder 405 to prevent the insert block 406 from retracting into the telescopic cylinder 405, and a positioning groove for plugging with the insert block 406 is provided on the rotating shaft 102c-2. A pressure-bearing layer 407 is fixed on the outside of the telescopic cylinder 405 . When the pressure inside the telescopic cylinder 405 is too high, the medium will flow into the pressure-bearing layer 407 .

[0059] In this embodiment, in order to improve the stability of the posture adjustment component 102 itself during use, an insert block 406 is additionally provided to lock the first hollow adjustment rod 102a and the second hollow adjustment rod 102b, so that the posture adjustment component 102 will not deviate from the shooting angle due to shaking or inertia during use.

[0060] Specifically, when there is no need to shoot in a narrow space, the plug block 406 will be plugged into the positioning groove on the rotating shaft 102c-2 to lock the rotating shaft 102c-2, thereby connecting the first hollow adjustment rod 102a, the second hollow adjustment rod 102b and the hollow gripping rod 101 as a whole to enhance the stability of the structure.

[0061] When it is necessary to adjust the angle of the first hollow adjustment rod 102a or the second hollow adjustment rod 102b, the staff can turn the control knob 401, and the control knob 401 drives the piston sleeve 402 to slide inside the piston cylinder 403 to reduce the pressure on the medium. The medium is preferably liquid or gas. Under the action of pressure, the medium will flow back into the piston cylinder 403, causing the plug 406 to retract, thereby separating from the positioning groove and releasing the lock on the rotating shaft 102c-2. At this time, the drive assembly 200 can adjust the angle of the first hollow adjustment rod 102a or the second hollow adjustment rod 102b; similarly, by squeezing the medium, the plug 406 can be inserted into the positioning groove to achieve locking. In addition, by adding a pressure-bearing layer 407, during the rotation of the rotating shaft 102c-2, the pressure generated by the medium will flow into the pressure-bearing layer 407, thereby buffering the plug 406 and avoiding excessive thrust on the plug 406 to interfere with the rotation of the rotating shaft 102c-2.
