Description

Technical Field

[0001] The utility model relates to a monitoring camera lifting device. Background Art

[0002] A surveillance camera is a semiconductor imaging device, which is generally installed outdoors through a camera bracket for image monitoring. Current surveillance cameras can all be remotely controlled. According to actual monitoring needs, the surveillance camera can be remotely controlled to rotate or raise its head up and down to change the monitoring range of the surveillance camera. It can be seen that after the surveillance camera is fixed through a camera bracket, the surveillance camera cannot change the height of its own position, and different heights can capture different images. In the actual remote monitoring process, the requirements for the monitoring range will also change according to different monitoring situations. Although the surveillance camera can perform wide-angle shooting, when the surveillance camera is always at the same height, the range that can be monitored is extremely limited. Summary of the invention

[0019] The disassembly and assembly structure includes a connecting hole 15 arranged at the center of the left end face of the lifting arm 14; a limiting groove 16 is arranged on the upper inner wall of the connecting hole 15, and the left notch of the limiting groove 16 is located on the left end face of the lifting arm 14; a connecting head 17 matching the connecting hole 15 is arranged at the center of the right end face of the camera bracket 1; a limiting block 18 matching the limiting groove 16 is arranged on the upper outer wall of the connecting head 17; an inner locking hole 19 is arranged on the lower outer wall of the connecting head 17; an outer locking hole 20 communicating with the inner locking hole 19 is arranged on the lower surface of the left end of the lifting arm 14; a gravity limiting member 21 matching therewith is arranged in the outer locking hole 20, and the upper end of the gravity limiting member 21 is upwardly inserted into the inner locking hole 19; a connecting nut 22 matching therewith is externally screwed on the left end of the lifting arm 14, and the lower end face of the gravity limiting member 21 is in contact with the inner wall of the connecting nut 22.

[0020] The outer wall of the connecting nut 22 is provided with a plurality of anti-slip protrusions 23 evenly distributed around the circumference.

[0021] The outer wall of the upper end of the gravity limiter 21 is provided with an introduction cone surface 32 which is narrow at the top and wide at the bottom.

[0022] The inner walls of the lifting chamber 4 at both the front and rear sides are provided with mutually symmetrical positioning grooves 24 ; the outer walls of the lifting sleeve 11 at both the front and rear sides are provided with positioning sliders 25 matching the positioning grooves 24 .

[0023] The left side walls at both ends of the lifting seat 3 are provided with a plurality of evenly distributed screw holes 26; the upper and lower ends of the protective cover 12 are provided with a plurality of fixing holes 27 that are connected with the screw holes 26; a fixing screw 28 passes through the fixing hole 27 to the right and is screwed into the corresponding screw hole 26, and the right side wall of the head of the fixing screw 28 is in contact with the left side wall of the protective cover 12.

[0024] The motor 7 is fixed to the upper surface of the lifting base 3 by a plurality of evenly distributed screws 29 .

[0025] The right side wall of the lifting seat 3 is provided with a plurality of evenly distributed fixing legs 30 ; the front and rear ends of the fixing legs 30 protrude outside the front and rear sides of the lifting seat 3 , and the front and rear ends of the fixing legs 30 are provided with mounting holes 31 .

[0026] The method of using the utility model is as follows:

[0027] When the height of the surveillance camera 2 needs to be adjusted, the motor 7 can be started. When the motor 7 is running, the motor 7 will drive the screw rod 9 to rotate through the coupling 8, and the bearing 10 arranged in the bearing hole 5 can effectively ensure the smoothness of the rotation of the screw rod 9. Since the lifting arm 14 passes through the lifting slot 13, the lifting arm 14 can only move up and down along the trajectory of the lifting slot 13, thereby limiting the lifting sleeve 11 to only move up and down, and the lifting sleeve 11 is screwed to the outside of the screw rod 9. When the screw rod 9 rotates, the lifting sleeve 11 can convert the rotating force into an up and down moving force, so that it can move up and down with the lifting arm 14, and the lifting arm 14 is connected to the camera bracket 1 through the disassembly structure. When the lifting sleeve 11 moves up and down, the camera bracket 1 drives the surveillance camera 2 to move up and down synchronously, effectively changing the height of the surveillance camera 2, thereby increasing the monitoring range of the surveillance camera 2.

[0028] When the surveillance camera 2 needs to be repaired or replaced, there is no need to disassemble the lifting seat 3, and the surveillance camera 2 can be disassembled separately, which reduces a lot of disassembly troubles. At this time, it is only necessary to rotate the connecting nut 22 to shift the connecting nut 22 so that the inner wall of the connecting nut 22 no longer covers the lower end opening of the outer positioning hole 20, and the gravity limiter 21 will fall downward under the action of its own weight, thereby disengaging from the inner positioning hole 19 and the outer positioning hole 20. As the gravity limiter 21 disengages, the connector 17 at the right end of the camera bracket 1 can be easily pulled out of the connecting hole 15, completing the disassembly of the surveillance camera 2. When installing the surveillance camera 2, you can first align the position of the limit block 18 and the limit slot 16. As the limit block 18 is inserted into the left notch of the limit slot 16, the connecting head 17 can be directly inserted into the connecting hole 15, thereby ensuring that after the connecting head 17 enters the connecting hole 15, the inner locking hole 19 and the outer locking hole 20 are in a coaxial state, which is convenient for the gravity limit member 21 to be inserted into the inner locking hole 19 through the outer locking hole 20, and then the connecting nut is used again to limit the lower part of the gravity limit member 21 in the outer locking hole 20, so as to complete the fixation between the connecting head 17 and the connecting hole 15, thereby completing the fixed connection between the lifting arm 14 and the camera bracket 1.

[0029] The outer wall of the connecting nut 22 is provided with a plurality of anti-skid protrusions 23 evenly distributed in a circumference. The presence of the anti-skid protrusions 23 can effectively increase the friction between the outer wall of the connecting nut 22 and the hand, making it easier to rotate the connecting nut 22.

[0030] The outer wall of the upper end of the gravity limiter 21 is provided with an introduction cone 32 which is narrow at the top and wide at the bottom. The existence of the introduction cone 32 makes it easier for the upper end of the gravity limiter 21 to be inserted into the lower end of the outer locking hole 20, thereby facilitating the assembly of the gravity limiter 21.

[0031] The inner walls on the front and rear sides of the lifting chamber 4 are provided with symmetrical positioning grooves 24, and the outer walls on the front and rear sides of the lifting sleeve 11 are provided with positioning sliders 25 matching the positioning grooves 24. The cooperation between the positioning sliders 25 and the positioning grooves 24 can further limit the moving trajectory of the lifting sleeve 11, thereby further ensuring the stability of the lifting sleeve 11 when moving up and down.

[0032] The left side walls at both ends of the lifting seat 3 are provided with a plurality of evenly distributed screw holes 26, and the upper and lower ends of the protective cover 12 are provided with a plurality of fixing holes 27 that intersect with the screw holes 26. A fixing screw 28 passes through the fixing hole 27 to the right and is screwed into the corresponding screw hole 26. The right side wall of the head of the fixing screw 28 fits with the left side wall of the protective cover 12. This fixing method facilitates the disassembly and assembly of the protective cover 12. At the same time, the existence of the protective cover 12 can restrict the screw rod 9 in the lifting chamber 4, which can not only ensure that the components in the lifting chamber 4 are not easily damaged, but also avoid injuries caused by accidental touch during the rotation of the screw rod 9.

[0033] The motor 7 is fixed to the upper surface of the lifting seat 3 by a plurality of evenly distributed screws 29 . This fixing method facilitates the disassembly and assembly of the motor 7 , thereby facilitating the maintenance and replacement of the motor 7 .

[0034] A plurality of evenly distributed fixing feet 30 are provided on the right side wall of the lifting seat 3. The front and rear ends of the fixing feet 30 protrude outside the front and rear sides of the lifting seat 3. The front and rear ends of the fixing feet 30 are provided with mounting holes 31. The existence of the mounting holes 31 makes it easy to fix the fixing feet 30 to the actual required fixing surface by screws.
