Specific implementation manner

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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 the embodiments.

[0029] Please refer to Figures 1-3 As shown, a monitoring electric lifting rod includes a bracket 3, a movable frame 8 and a wire winding wheel 9. A lead screw 5 driven to rotate by a motor 1 is rotatably connected to the middle of the bracket 3; the movable frame 8 is slidably connected to the bracket 3 along the length direction of the lead screw 5, and a lead screw sleeve 7 is sleeved outside the lead screw 5, and the lead screw sleeve 7 is fixedly connected to the movable frame 8; the wire winding wheel 9 is rotatably connected to the bracket 3 and is driven to rotate by the lead screw 5, and the wire winding wheel 9 is used for unwinding or winding the wire during the lifting and lowering of the movable frame 8.

[0030] The motor 1 drives the lead screw 5 to rotate. Under the interaction of the lead screw 5 and the lead screw sleeve 7, the movable frame 8 is driven to lift and lower, so that it can stop at any height, making the height adjustment more convenient; during the height adjustment process, the lead screw 5 drives the wire winding wheel 9 to rotate, realizing the unwinding or winding of the wire and straightening the wire.

[0031] By synchronously unwinding or winding the wire, the problem of too long wire being wound and knotted, which affects the lifting and lowering of the movable frame 8, is avoided; at the same time, the problem of the wire being too tight, resulting in excessive tension, damage and breakage, which affects the normal operation of the equipment, is avoided.

[0032] In order to increase the height of the lifting frame, a slide bar 6 is fixedly connected to the top end of the movable frame 8, and a limit cylinder 2 is sleeved outside the slide bar 6, and the limit cylinder 2 is fixedly connected to the bracket 3. Preferably, there are two slide bars 6, and the lifting frame is made more stable by arranging two slide bars 6.

[0033] During use, the camera 16 is fixed to the top end of the slide bar 6. By arranging the limit cylinder 2 to assist in positioning the slide bar 6, the slide bar 6 is made more stable during use, avoiding the shaking of the captured image.

[0034] In order to further improve the stability during the lifting process, the movable frame 8 is slidably connected to the bracket 3 through a slide rail 4. Preferably, the bracket 3 is rectangular, and slide rails 4 are fixedly connected to both sides inside the rectangular bracket 3, and both ends of the movable frame 8 are slidably connected to the bracket 3 through the slide rails 4. By arranging two slide rails 4, the lifting of the movable frame 8 is made more stable.

[0035] Specifically, the motor 1 is fixedly connected to the top end of the bracket 3, and the wire coiling wheel 9 is rotatably connected to the bottom end of the bracket 3. The wire coiling wheel 9 is arranged at the bottom end of the bracket 3 to facilitate wire connection and arrangement operations. The sliding rod 6 is a hollow tube, and the wire is threaded through the sliding rod 6, and the wire can be protected through the sliding rod 6.

[0036] When the sliding rod 6 rises, a section of wire between the bottom end of the sliding rod 6 and the wire coiling wheel 9 will be exposed. To protect this section of wire, a protective tube is inserted through the middle of the sliding rod 6, and the bottom end of the protective tube is fixedly connected to the bracket 3. The wire is protected by the protective tube, and the protective tube is a rigid tube to avoid bending.

[0037] To protect the wire and prevent it from being worn, an elastic protective sleeve 13 is fixedly connected to the position where the bracket 3 contacts the wire.

[0038] In some embodiments, a bevel gear disk 15 is fixedly connected to one side of the wire coiling wheel 9, and a bevel gear 14 is fixedly connected to one end of the lead screw 5. The bevel gear 14 meshes with the bevel gear disk 15.

[0039] The lead screw 5 drives the wire coiling wheel 9 to rotate under the cooperation of the bevel gear 14 and the bevel gear disk 15. It should be noted that the length of the wire wound and unwound by the wire coiling wheel 9 during rotation needs to be consistent with the lifting height of the movable frame 8, which can be achieved by controlling the tooth number ratio of the bevel gear 14 and the bevel gear disk 15.

[0040] In some embodiments, to prevent the wire from becoming slack, two swing rods 11 are symmetrically arranged above the wire coiling wheel 9. One end of the swing rod 11 is rotatably connected to the bracket 3, and the other end of the swing rod 11 is rotatably connected to a tensioning wheel 12. A tension spring 10 is connected between the swing rod 11 and the bracket 3, and the tension spring 10 is used to pull the swing rod 11 to make the two tensioning wheels 12 move away from each other.

[0041] During use, the wire unwound from the wire coiling wheel 9 is sequentially wound around the two tensioning wheels 12. Under the action of the tension spring 10, the two swing rods 11 are pulled to rotate, and the two tensioning wheels 12 move away from each other, thereby tensioning the wire and preventing the wire from becoming slack and affecting the winding and unwinding of the wire by the wire coiling wheel 9.

[0042] Specifically, the tensioning wheel 12 is a grooved wheel. The grooved wheel is used to limit the wire.

[0043] Specifically, an outer shell 17 is provided on the outside of the wire coiling wheel 9 to protect the wire coiling wheel 9, and a support 18 is fixedly connected to the bottom end of the bracket 3.

[0044] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
