[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0026] This embodiment proposes a pipeline inspection periscope telescopic rod quick-release structure, such as Figures 1 to 4As shown, it includes a support plate 1 and a telescopic rod 6. The right end of the support plate 1 is installed with a pipeline detection periscope probe body 2, and the upper end of the support plate 1 is installed with a connecting rod 5. When in use, the telescopic rod 6 is connected to the connecting rod 5 through a bolt, and the pipeline detection periscope probe body 2 is placed into the pipeline through the telescopic rod 6. The interior of the pipeline is observed through the pipeline detection periscope probe body 2. However, when using bolts to fix and disassemble, tools are required to operate, the operation is relatively cumbersome, the operation time is long, and work efficiency is affected.

[0027] In order to solve the above-mentioned drawbacks, when the first frustum block 9 moves downward along the axial direction of the telescopic rod 6 and squeezes the triangular slider 11, the two triangular sliders 11 move away from each other until the first frustum block 9 no longer squeezes the triangular slider 11, and the two triangular sliders 11 move close to each other and complete the fixing operation of the telescopic rod 6. Specifically: a first circular groove 10 is provided at the upper end of the connecting rod 5, and a fixing rod 8 is installed in the first circular groove 10. The upper end of the fixing rod 8 is installed with a first frustum block 9, and a circular ring 7 is installed at the lower end of the telescopic rod 6. The circular ring 7 is equipped with a triangular slider 11 along its radial sliding assembly, and two triangular sliders 11 are provided and symmetrically arranged. Two second circular grooves 72 are provided inside the circular ring 7, and two rectangular grooves 71 are provided on the inner wall surface of the circular ring 7. A reset component 12 is provided in the second circular groove 72, and two reset components 12 are provided. The reset component 12 is used to drive the triangular slider 11 to reset; reset part Component 12 includes a reset rod 121, which is arranged in the second circular groove 72. The outer surface of the reset rod 121 is movably sleeved with a second spring 123. One end of the reset rod 121 movably passes through the outer surface of the ring 7 and is fixedly connected to the knob 124. The other end of the reset rod 121 is movably inserted into the rectangular groove 71 and fixedly connected to the triangular slider 11. The second spring 123 is fixedly connected to a circular plate 122 near the triangular slider 11. When in use, the telescopic rod 6 is moved to the top of the first frustum block 9 and then moved downward. After the triangular slider 11 contacts the first frustum block 9, it is pressured to move outward to the rectangular groove 71, and the second spring 123 is compressed. When the triangular slider 11 moves to the bottom of the first frustum block 9, the second spring 123 drives the triangular slider 11 to move inward and move to the bottom of the first frustum block 9, thereby completing the fixation between the pipeline inspection periscope probe body 2 and the telescopic rod 6.

[0028] In order to quickly disassemble the connecting rod 5 and the telescopic rod 6, a second frustum block 13 is movably sleeved on the outer surface of the fixed rod 8. During disassembly, the telescopic rod 6 is driven to continue to move downward. The triangular slider 11 is squeezed by the second frustum block 13 and moves outward until the triangular slider 11 moves to the bottom of the upper end surface of the second frustum block 13, and then drives the telescopic rod 6 upward. When the triangular slider 11 is against the middle of the outer surface of the second frustum block 13, it continues to drive the telescopic rod 6 upward. The triangular slider 11 drives the second frustum block 13 upward through friction until it contacts the first frustum block 9. At this time, the triangular slider 11 can cross the second frustum block 13, and continue to move the telescopic rod 6 upward. The triangular slider 11 moves to the outer surface of the first frustum block 9 through the outer surface of the second frustum block 13 to complete the separation. The operation is simple, no tools are required, the operation time is short, and work efficiency is improved.

[0029] In order to ensure smooth contact between the triangular slider 11 and the first frustum block 9, the triangular slider 11 is radially slidably assembled in the rectangular groove 71 along the circular ring 7, and in the initial state, a small part of the triangular slider 11 is located in the rectangular groove 71, and the remaining part is located outside the rectangular groove 71, which is convenient for contact with the first frustum block 9.

[0030] In order to realize the automatic reset of the triangular slider 11, the circular plate 122 is fixedly mounted on the reset rod 121. The circular plate 122 and the second spring 123 are both located in the second circular groove 72. The circular plate 122 is used to squeeze the second spring 123 and transmit the elastic force of the second spring 123 in time.

[0031] In addition, in this embodiment, the outer surface of the triangular slider 11 matches the first frustum block 9 and the second frustum block 13, the end of the triangular slider 11 that contacts the first frustum block 9 and the second frustum block 13 is a flat head, the first frustum block 9 and the second frustum block 13 have the same shape, and the first frustum block 9 and the second frustum block 13 are symmetrically distributed up and down.

[0032] On the basis of the above scheme, after the second frustum block 13 is driven to move upward by the triangular slider 11, in order to enable the second frustum block 13 to automatically reset and facilitate the subsequent triangular slider 11 to move to the bottom of the first frustum block 9, a first spring 14 is fixedly connected to the lower end of the second frustum block 13. The first spring 14 is movably mounted on the fixed rod 8, and the lower end of the first spring 14 is fixedly connected to the bottom wall of the first circular groove 10. After the second frustum block 13 moves upward, the first spring 14 generates elastic properties. After the triangular slider 11 moves away from the second frustum block 13, the first spring 14 drives the second frustum block 13 to move downward. The elastic force of the first spring 14 is less than the friction force of the contact between the triangular slider 11 and the second frustum block 13.

[0033] In addition, since there are many pollutants in the pipeline, once they enter the ring 7, they will affect the operation of the disassembly structure. In order to prevent impurities from entering the ring 7, a telescopic cover 15 is fixed on the outer surface of the connecting rod 5, and a magnet 16 is installed on the upper end of the telescopic cover 15. During installation, the telescopic cover 15 is connected to the bottom of the ring 7 through the magnet 16 to prevent foreign matter from entering the ring 7, ensuring that the triangular slider 11 and the reset component 12 can move normally, thereby ensuring the stability of the device. During disassembly, a force greater than the magnetic force of the magnet 16 is applied, and the telescopic cover 15 facilitates the separation of the ring 7.

[0034] In order to prevent the pipeline inspection periscope probe body 2 from being hit, a fixed block 3 is fixedly connected to the left end of the support plate 1. A shock-absorbing support scale assembly 4 is provided inside the fixed block 3 through a screw sleeve. The shock-absorbing support scale assembly 4 is composed of a guide rod, a spring and an anti-collision block. When the pipeline inspection periscope probe body 2 is about to contact a hard object, the shock-absorbing support scale assembly 4 can prevent the pipeline inspection periscope probe body 2 from continuing to move downward.
