[0008] Further, the main support rod is a cylindrical rod, the support ring is a circular tubular structure, and the support ring can slide up and down and rotate outside the main support rod.

[0009] Further, a circular hole with the same diameter as the main body part of the positioning pin is provided on both the support ring and the CCD camera support block. When the arc-shaped raised strip on the outer wall of the support ring is embedded into the arc-shaped groove inside the arc-shaped groove on one side of the auxiliary positioning plate, the rear end of the positioning pin can be embedded into the vertical strip-shaped groove outside the main support rod.

[0010] Further, a vertical arc groove is provided on one side of the auxiliary positioning plate close to the main support rod, and the radian of the arc groove is the same as that of the outer wall of the support ring.

[0011] Further, the cylindrical block at the front end of the positioning pin is a magnet block, and the CCD camera support block is an iron block.

[0012] Further, five arc-shaped raised strips are equidistantly arranged on the outer wall of the support ring, and a number of corresponding arc-shaped grooves are also equidistantly arranged on the inner side of the arc groove on one side of the auxiliary positioning plate.

[0013] The utility model provides a lifting and adjusting structure for a CCD photographing mechanism, which has the following beneficial effects:

[0014] The support ring in the utility model can slide up and down outside the main support rod to adjust, so as to lift and adjust the CCD camera.

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0027] Embodiment 1: Please refer to Figures 1 to 6 :

[0028] The present utility model provides a lifting and adjusting structure for a CCD photographing mechanism, including: a base 1;

[0029] A main support rod 2 is welded to the top of the base 1. The base 1 is used to support the main support rod 2 and the auxiliary positioning plate 3, and the main support rod 2 is used to support the support ring 4; an auxiliary positioning plate 3 is also welded to the top of the base 1. During use, the support ring 4 can be rotated 90° so that the arc-shaped protruding strip on its outer wall is embedded into the arc-shaped groove on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3, thus restricting the up-and-down sliding of the support ring 4; a support ring 4 is installed outside the main support rod 2, and the support ring 4 is used to support the CCD camera support block 5. When the height of the CCD camera 6 needs to be adjusted, the support ring 4 can be rotated 90° outside the main support rod 2. At this time, the arc-shaped protruding strip on the outer wall of the support ring 4 will disengage from the arc-shaped groove on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3, thus enabling the support ring 4 to slide up and down outside the main support rod 2; a CCD camera support block 5 is welded to the front side of the support ring 4, and the CCD camera support block 5 is used to support the CCD camera 6; a CCD camera 6 is installed on the top of the CCD camera support block 5, and the CCD camera 6 is used to take pictures; a positioning pin 7 is also embedded and installed inside the CCD camera support block 5. After the support ring 4 is adjusted, the positioning pin 7 can be pushed backward to the rearmost side. During this process, the rear end of the positioning pin 7 will be re-embedded into the vertical strip-shaped groove outside the main support rod 2, thus restricting the rotation of the support ring 4.

[0030] In the embodiments of the present disclosure, as Figures 1-4As shown in the figure, a vertical strip-shaped groove is provided on the outer side of the main support rod 2, and the width of the vertical strip-shaped groove is equal to the diameter of the main body part of the positioning pin 7. After the support ring 4 is adjusted, the positioning pin 7 can be pushed backward to the rearmost side. During this process, the rear end of the positioning pin 7 will re-embed into the vertical strip-shaped groove on the outer side of the main support rod 2, so the rotation of the support ring 4 can be restricted.

[0031] In the embodiment of the present disclosure, as Figures 1-6 shown in the figure, the main support rod 2 is a cylindrical rod, and the support ring 4 is a circular tubular structure. The support ring 4 can slide up and down and rotate on the outer side of the main support rod 2. When it is necessary to adjust the height of the CCD camera 6, the support ring 4 can be rotated 90° on the outer side of the main support rod 2. At this time, the arc-shaped protruding strip on the outer wall of the support ring 4 will disengage from the arc-shaped groove on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3. Therefore, the support ring 4 can be pushed to slide up and down on the outer side of the main support rod 2, and then the CCD camera 6 can be lifted and lowered.

[0032] In the embodiment of the present disclosure, as Figure 4 shown in the figure, a circular hole equal to the diameter of the main body part of the positioning pin 7 is provided on both the support ring 4 and the CCD camera support block 5. When the arc-shaped protruding strip on the outer wall of the support ring 4 is embedded in the arc-shaped groove on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3, the rear end of the positioning pin 7 can be embedded in the vertical strip-shaped groove on the outer side of the main support rod 2. When it is necessary to adjust the height of the CCD camera 6, first pull the positioning pin 7 forward a certain distance from the circular hole inside the CCD camera support block 5 and the circular hole on the support ring 4. At this time, the rear end of the positioning pin 7 will disengage from the vertical strip-shaped groove on the outer side of the main support rod 2, and then the support ring 4 can be rotated on the outer side of the main support rod 2. After the support ring 4 is adjusted, the positioning pin 7 can be pushed backward to the rearmost side. During this process, the rear end of the positioning pin 7 will re-embed into the vertical strip-shaped groove on the outer side of the main support rod 2, so the rotation of the support ring 4 can be restricted.

[0033] In the embodiment of the present disclosure, as Figures 1-3 shown in the figure, a vertical arc-shaped groove is provided on the side of the auxiliary positioning plate 3 close to the main support rod 2, and the radian of the arc-shaped groove is the same as the radian of the outer wall of the support ring 4. Therefore, when the support ring 4 rotates, it can rotate in the arc-shaped groove on one side of the auxiliary positioning plate 3 without conflict.

[0034] In the embodiment of the present disclosure, as Figures 1-6As shown in the figure, five arc-shaped raised strips are equidistantly arranged on the outer wall of the support ring 4, and a number of corresponding arc-shaped grooves are also equidistantly arranged on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3. When it is necessary to adjust the height of the CCD camera 6, the support ring 4 can be rotated 90° outside the main support rod 2. At this time, the arc-shaped raised strips on the outer wall of the support ring 4 will disengage from the arc-shaped grooves on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3. Therefore, the support ring 4 can be pushed to slide up and down outside the main support rod 2, and then the CCD camera 6 can be lifted and lowered. After adjusting the height, the support ring 4 is rotated 90° again to make the arc-shaped raised strips on its outer wall re-embed into the arc-shaped grooves on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3, so that the up and down sliding of the support ring 4 can be restricted.

[0035] Embodiment 2, on the basis of Embodiment 1, as Figures 1-6 shown, the cylindrical block at the front end of the positioning pin 7 is a magnet block, and the CCD camera support block 5 is an iron block. After the adjustment of the support ring 4 is completed, the positioning pin 7 can be pushed backward to the rearmost side. During this process, the rear end of the positioning pin 7 will re-embed into the vertical strip-shaped groove on the outer side of the main support rod 2. Therefore, the rotation of the support ring 4 can be restricted, and at this time, the magnet block at the front end of the positioning pin 7 will adsorb to the CCD camera support block 5 to prevent the positioning pin 7 from loosening.

[0036] The working principle of this embodiment: When installing, the base 1 can be fixed at the use position of the CCD camera 6. When it is necessary to adjust the height of the CCD camera 6, first pull the positioning pin 7 forward a certain distance from the round hole inside the CCD camera support block 5 and the round hole on the support ring 4. At this time, the rear end of the positioning pin 7 will disengage from the vertical strip-shaped groove on the outer side of the main support rod 2, and then the support ring 4 can be rotated 90° outside the main support rod 2. At this time, the arc-shaped raised strips on the outer wall of the support ring 4 will disengage from the arc-shaped grooves on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3. Therefore, the support ring 4 can be pushed to slide up and down outside the main support rod 2. After adjusting the height, the support ring 4 is rotated 90° again to make the arc-shaped raised strips on its outer wall re-embed into the arc-shaped grooves on the inner side of the arc-shaped groove on one side of the auxiliary positioning plate 3, so that the up and down sliding of the support ring 4 can be restricted. Then, the positioning pin 7 is pushed backward to the rearmost side again. During this process, the rear end of the positioning pin 7 will re-embed into the vertical strip-shaped groove on the outer side of the main support rod 2. Therefore, the rotation of the support ring 4 can be restricted, and then the height of the CCD camera 6 can be fixed to achieve lifting adjustment.
