Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to a safety monitoring device for radio and television equipment. Background Technique

[0002] The television monitoring system mainly consists of two major parts: front-end equipment and back-end equipment. The front-end equipment usually consists of components such as cameras, manual or motorized lenses, pan-tilt heads, protective enclosures, microphones, alarm detectors, and multi-functional decoders. They each perform their own functions and establish corresponding connections with various devices in the central control system through wired, wireless, or fiber optic transmission media. In an actual television monitoring system, these front-end equipment may not be used simultaneously, but cameras and lenses for collecting on-site monitoring images are essential. The back-end equipment can be further divided into central control equipment and sub-control equipment.

[0003] Referring to the Chinese patent with the authorized announcement number CN215488936U, it discloses a safety monitoring device for radio and television equipment. The device can complete the positioning of the height position of the device through the inner rod inside the movable hollow column and can cooperate with the positioning holes on the inner rod through the positioning rods on the inner side of the connecting plate, thereby achieving the height adjustment effect of the camera.

[0004] However, when adjusting the height of the camera with the above device, it is necessary to pull out the positioning rod from the positioning hole, cancel the limit of the positioning rod, and then the inner rod can be telescopically adjusted. After the adjustment is completed, it is also necessary to align and insert the positioning rod into the positioning hole at the same height. The operation process is cumbersome and not convenient enough. Content of the Utility Model

[0005] The purpose of the utility model is to provide a safety monitoring device for radio and television equipment with convenient and fast height adjustment, effectively solving the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions.

[0007] A safety monitoring device for radio and television equipment, comprising a connecting seat and a camera. There is an inner cavity in the middle of the connecting seat. On both sides of the inner cavity in the connecting seat, there are vertically extending and vertically penetrating telescopic grooves. The two sides of the inner cavity communicate with the telescopic grooves. A shaft rod is rotatably installed in the inner cavity, and a gear is fixedly sleeved on the shaft rod. A first rack is slidably installed in one of the telescopic grooves, and the upper end of the first rack extends above the connecting seat. A second rack is slidably installed in the other telescopic groove, and the lower end of the second rack extends below the connecting seat. Both the first rack and the second rack are engaged with the gear. A driving mechanism is provided on the side of the connecting seat, and the driving mechanism is used to drive the shaft rod to rotate. The driving mechanism includes a bracket, a worm and a worm gear. The worm is rotatably installed on the side of the connecting seat through the bracket, and one end of the shaft rod penetrates and extends to the outside of the connecting seat. The worm gear is fixed on the outer end of the shaft rod and is correspondingly engaged with the worm. The camera is arranged above the top of the first rack through an angle adjustment mechanism, and the angle adjustment mechanism is used to adjust the monitoring angle of the camera.

[0008] Thus, it is convenient to adjust the shooting angle of the camera by operating the angle adjustment mechanism. By turning the worm, the rotating worm can engage and drive the worm gear and drive the shaft rod to rotate. The rotating shaft rod drives the gear to rotate, and the rotating gear can engage and drive the first rack and the second rack to telescopically move in the telescopic groove, thereby realizing the height adjustment of the camera. Moreover, the first rack and the second rack are of a two-way telescopic type. When the gear rotates, it can simultaneously drive the first rack and the second rack to expand and contract, making the lifting adjustment of the camera faster. Cooperating with the connecting seat to achieve a three-stage adjustment effect, the height adjustment range of the camera is larger. At the same time, by using the one-way transmission effect of the worm and the worm gear, the shaft rod and the gear have a self-locking effect. When the worm is not rotated and adjusted, there is no need to use additional positioning parts to fix the first rack and the second rack, which can ensure that the camera will not lift or lower randomly, saving the trouble of disassembling, installing or re-arranging the positioning parts when adjusting the height of the camera, making the lifting adjustment of the camera more convenient and fast.

[0009] Furthermore, the angle adjustment mechanism includes a mounting seat, an adjustment ball, a fixing rod and a threaded rod. The mounting seat is fixed at the upper end of the first rack. There is a spherical cavity penetrating the top of the mounting seat in the mounting seat. A threaded hole horizontally extending and communicating with the spherical cavity is provided on the side surface of the mounting seat. The adjustment ball is movably installed in the spherical cavity, and part of it is exposed above the mounting seat. The fixing rod is fixed on the exposed surface of the spherical cavity. The camera is fixed at the end of the fixing rod. The threaded rod is threadedly installed in the threaded hole.

[0010] By tightening the threaded rod, the threaded rod extends into the spherical cavity and abuts against the adjusting ball, realizing the fastening of the adjusting ball, avoiding the change of the shooting angle of the camera caused by the movement of the adjusting ball in the spherical cavity, and further ensuring the stability of the camera during monitoring. By turning the threaded rod, the threaded rod retracts into the threaded hole, canceling the abutting fastening of the adjusting ball. At this time, the adjusting ball can move and adjust in the spherical cavity, facilitating the adjustment of the monitoring angle of the camera. Through the multi-directional rolling of the adjusting ball in the spherical cavity, the angle adjustment range of the camera is larger, realizing multi-directional monitoring.

[0011] Furthermore, vertical extension limiting grooves are symmetrically arranged on both sides of the connecting seat, and the limiting grooves communicate with the corresponding telescopic grooves on the same side; limiting blocks are installed in the limiting grooves in a limited sliding manner. One of the limiting blocks extends into the telescopic groove and is fixedly connected to the side of the first rack and near the bottom end of the first rack, and the other limiting block extends into the telescopic groove and is fixedly connected to the side of the second rack and near the top end of the second rack.

[0012] When the first rack and the second rack are telescopically adjusted, the limiting blocks can be driven to slide synchronously in the limiting grooves. By using the blocking effect of the inner wall of the limiting grooves on the limiting blocks, a limiting effect on the first rack and the second rack is achieved, avoiding the first rack and the second rack from being telescopically extended too much and disengaging from the telescopic grooves.

[0013] Furthermore, an extension rod is fixed to one end of the worm, the extension rod extends to the side of the shaft rod, and a rocking disc is installed at the end of the extension rod.

[0014] By using the extension rod to install the rocking disc at the end of the worm, turning the rocking disc makes the screwing adjustment of the worm more convenient and labor-saving. Secondly, by using the extension rod to install the rocking disc on the side of the connecting seat, it is avoided that the rocking disc and the outer wall of the connecting seat block each other and affect the rocking adjustment of the rocking disc.

[0015] Furthermore, one end of the threaded rod extends to the outside of the mounting seat, and a rotating handle is installed on the outer end of the threaded rod, and the outer surface of the rotating handle has anti-slip threads.

[0016] By installing a rotating handle at one end of the threaded rod, it is convenient to exert force to screw and adjust the threaded rod by holding the rotating handle. At the same time, anti-slip threads are provided on the rotating handle, increasing the friction with the palm and avoiding the situation of slipping and dropping the hand.

[0017] Furthermore, a fixed base is fixed to the lower end of the second rack, and the fixed base can be fixed to the installation position by bolts.

[0018] By using bolts to fix the fixed base to the installation position, the installation is firm and convenient, and at the same time, the fixed base has a detachable effect, facilitating the removal of the whole for maintenance and repair.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows.

[0020] 1. The utility model can mesh with the worm gear and drive the shaft to rotate by twisting the worm, and the rotating shaft drives the gear to rotate, and the rotating gear can mesh with the first rack and the second rack to telescopically move in the telescopic groove, thereby realizing the height adjustment of the camera. The one-way transmission effect of the worm and the worm gear is utilized to make the shaft and the gear have a self-locking effect. When the worm is not screwed to adjust, there is no need to use additional positioning parts to fix the first rack and the second rack, so as to ensure that the camera will not be raised or lowered at will, eliminating the trouble of disassembling or rearranging the positioning parts when adjusting the height of the camera, making the lifting and lowering adjustment of the camera more convenient and quick.

[0021] 2. The first rack and the second rack provided in the utility model are bidirectionally retractable. When the gear rotates, the first rack and the second rack can be driven to retract at the same time, so that the lifting and lowering adjustment of the camera is faster, and cooperates with the connecting seat to achieve a three-stage adjustment effect, so that the height adjustment range of the camera is larger.

[0022] 3. The utility model twists the threaded rod to retract the threaded rod into the threaded hole, thereby eliminating the interference and tightening of the adjusting ball. At this time, the adjusting ball can be movably adjusted in the spherical cavity, which is convenient for adjusting the monitoring angle of the camera. By allowing the adjusting ball to roll in multiple directions in the spherical cavity, the angle adjustment range of the camera is expanded, thereby achieving multi-directional monitoring.

[0030] When the height of the camera 8 is adjusted in this device, the shooting angle of the camera 8 can be adjusted conveniently by operating the angle adjustment mechanism 7 to change the monitoring angle of the camera 8. By turning the worm 62, the rotating worm 62 can engage and drive the worm gear 63 and drive the shaft rod 2 to rotate. The rotating shaft rod 2 drives the gear 3 to rotate. The rotating gear 3 can engage and drive the first rack 4 and the second rack 5 to telescopically move in the telescopic groove 12, thereby realizing the height adjustment of the camera 8. Moreover, the first rack 4 and the second rack 5 are of a two-way telescopic type.
