Description

Technical Field

[0001] The present invention relates to the field of monitoring technology, and in particular to a monitoring equipment supporting structure. Background Art

[0002] Monitor refers to the general term for recording and storing video and audio signals using video storage devices. With the increasing popularity of closed-circuit surveillance in civil and commercial applications, surveillance cameras are widely used in various fields. Surveillance cameras are usually fixed to the wall through a bracket. Since there is often airflow in the air, the airflow will form an alternating vortex pattern downstream when it passes through the camera bracket, which will produce the Karman vortex street phenomenon, which will cause the camera bracket to vibrate, affecting the stability of the camera bracket and thus the quality of the surveillance video. Summary of the invention

[0003] Based on this, it is necessary to provide a monitoring equipment support structure to address the technical problem that the current camera bracket vibrates under the action of airflow.

[0004] The above purpose is achieved through the following technical solutions:

[0006] Furthermore, two first springs are provided in the middle position of the sliding rod, and the two first springs are respectively connected to a rotating rod. When the two rotating rods are parallel to the sliding rod, the two first springs are in dead point positions; when the sliding rod starts to slide under the action of the airflow, the first spring is no longer in the dead point position, thereby pushing the sliding rod to slide.

[0009] Furthermore, the second transmission mechanism includes a second rotating gear, which is fixed to the top end of the sliding rod, and a driving groove is provided on the mounting seat. A first rack is provided at the bottom of the driving groove, and the first rack is meshed with the second rotating gear. A horizontal sliding groove is provided on the front and rear side walls of the driving groove, and the second rotating gear can slide along the horizontal sliding groove.

[0010] Furthermore, a slide rail is provided on the bottom plate, and the slider can slide along the slide rail.

A left sliding gear and a right sliding gear are respectively meshed on the left and right sides of the reset gear, and both the left sliding gear and the right sliding gear have a gear shaft. A left arc groove and a right arc groove are also provided on the shell, and the gear shaft of the left sliding gear and the bottom of the left arc groove are connected with a second spring, and the gear shaft of the left sliding gear can slide along the left arc groove; the gear shaft of the right sliding gear and the bottom of the right arc groove are connected with a third spring, and the gear shaft of the right sliding gear can slide along the right arc groove.

[0012] Furthermore, a second rack is provided in the slide rail, and the second rack can be meshed with the left sliding gear or the right sliding gear.

[0013] Furthermore, the base plate is fixed to the wall by bolts.

[0014] Furthermore, a camera is rotatably provided on the mounting seat.

[0015] The beneficial effects of the present invention are:

[0016] A monitoring equipment support structure provided by the present invention, when encountering an airflow perpendicular to the support rod group, the airflow will push the sliding rod to move on the bottom plate and cause the two rotating rods to rotate, so that the sliding rod and the two rotating rods form a conical structure, and the conical structure can break the Karman vortex street effect, improve the seismic resistance of the monitoring equipment support structure, and thus improve the camera quality; at the same time, a triangular support structure is formed, which on the one hand improves the support stability, and on the other hand can shorten the distance between the camera and the wall, thereby reducing the impact of the airflow on the mounting seat.

[0029] like Figures 1 to 8 As shown, a monitoring equipment support structure provided by an embodiment of the present invention includes a base plate 100 and a mounting seat 300; a support rod group 200 is arranged between the mounting seat 300 and the base plate 100, and the support rod group 200 includes two rotating rods 220 and a sliding rod 210 arranged front and back, and the sliding rod 210 is located between the two rotating rods 220, and a windshield 213 is arranged on the sliding rod 210; in the initial state, the two rotating rods 220 are arranged parallel to the sliding rod 210; when encountering an airflow perpendicular to the support rod group 200, the airflow will push the sliding rod 210 to move left and right under the action of the windshield 213, and the sliding rod 210 moves through the mounting seat 300 to drive the two rotating rods 220 to rotate, so that the support rod group 200 is conical. In this embodiment, the windshield 213 is located at the front and rear sides of the sliding rod 210, so that it can be moved more easily under the push of the airflow.

[0030] In one embodiment, two first springs 211 are provided at the middle position of the sliding rod 210, and the two first springs 211 are respectively connected to a rotating rod 220 (the middle section of the first spring 211 is omitted in the figure). When the two rotating rods 220 are parallel to the sliding rod 210, the two first springs 211 are both at the dead point position; when the sliding rod 210 starts to slide a short distance under the action of the airflow, the first spring 211 is no longer at the dead point position, thereby releasing the elastic force to push the sliding rod 210 to slide relative to the rotating rod 220.

[0031] In one embodiment, the bottom end of the rotating rod 220 is hinged to the hinge seat 110 of the bottom plate 100 through the third hinge shaft 221, the top end of the rotating rod 220 is connected to the mounting seat 300 through the first transmission mechanism, the bottom end of the sliding rod 210 is hinged to the slider 120 through the first hinge shaft 212, the slider 120 is slidably arranged on the bottom plate 100, and the top end of the sliding rod 210 is connected to the mounting seat 300 through the second transmission mechanism; the rotation axis of the bottom end of the sliding rod 210 is not coaxial with the rotation axis of the bottom end of the rotating rod 220. In this way, in the initial state, the support rod group 200 will not rotate to one side, so as to prevent the camera 400 from rotating.

[0032] In one embodiment, the first transmission mechanism includes a first rotating gear 222, which is fixed to the top of the rotating rod 220. A half gear 320 is fixed to the mounting base 300, and the rotating gear is meshed with the half gear 320. Fixed blocks 310 are provided on the front and rear sides of the half gear 320, and the rotating gear is hinged to the fixed block 310.

[0033] In one embodiment, the second transmission mechanism includes a second rotating gear 214, which is fixed to the top end of the sliding rod 210. A driving groove is provided in the middle position of the mounting seat 300, and the driving groove extends in the left and right directions. A first rack 330 is provided at the bottom of the driving groove, and the first rack 330 is meshed with the second rotating gear 214. A horizontal sliding groove 340 is provided on the front and rear side walls of the driving groove. A second hinge shaft 215 is provided on the second rotating gear 214, and the second hinge shaft 215 can slide along the horizontal sliding groove 340.

[0034] In one embodiment, a slide rail 130 is disposed on the bottom plate 100 , and the slider 120 can slide along the slide rail 130 .

[0035] In one embodiment, if Figure 4As shown, a reset mechanism 500 is fixed on the slider 120, and the reset mechanism 500 includes a shell and a reset motor. A reset gear 510 is rotatably provided on the shell, and the reset gear 510 is transmission-connected to the output shaft of the reset motor. The left and right sides of the reset gear 510 are respectively meshed with a left sliding gear 540 and a right sliding gear 520, and the left sliding gear 540 and the right sliding gear 520 both have gear shafts. A left arc groove and a right arc groove are also provided on the shell. The gear shaft of the left sliding gear 540 and the bottom of the left arc groove are connected with a second spring 550, and the gear shaft of the left sliding gear 540 can slide along the left arc groove; the gear shaft of the right sliding gear 520 and the bottom of the right arc groove are connected with a third spring 530, and the gear shaft of the right sliding gear 520 can slide along the right arc groove.

[0036] In one embodiment, a second rack 131 is further provided in the slide rail 130, and the second rack 131 can mesh with the left sliding gear 540 or the right sliding gear 520. When the left sliding gear 540 slides to the bottom of the left arc-shaped groove, the left sliding gear 540 can mesh with the second rack 131 for transmission; when the right sliding gear 520 slides to the bottom of the right arc-shaped groove, the right sliding gear 520 can mesh with the second rack 131 for transmission.

[0037] In one embodiment, the base plate 100 is fixed to the wall by bolts.

[0038] In one embodiment, a camera 400 is rotatably mounted on the mounting base 300 .

[0039] In combination with the above embodiments, the use principle and working process of a monitoring equipment support structure according to an embodiment of the present invention are as follows:

[0040] In the initial state, the sliding rod 210 and the two rotating rods 220 are in a parallel state, and the first spring 211 is in a dead point position. At this time, since the rotation axis of the bottom end of the sliding rod 210 is not coaxial with the rotation axis of the bottom end of the rotating rod 220, the support rod group 200 formed by the rotating rod 220 and the sliding rod 210 will not rotate, thereby ensuring the normal support of the support structure of the monitoring equipment; when there is an airflow perpendicular to the support rod group 200, the windshield plate 213 on the sliding rod 210 drives the sliding rod 210 to move a short distance in the direction of the airflow under the push of the airflow. , then the first spring 211 is no longer at the dead point position, and the first spring 211 releases its elastic force to push the sliding rod 210 and the two rotating rods 220 away from each other. Since the slider 120 at the bottom end of the sliding rod 210 slides in the slide rail 130, the top end of the sliding rod 210 slides in the horizontal slide groove 340 of the mounting seat 300, so that both ends of the sliding rod 210 will move, while the rotating rod 220 cannot move. Since the top end of the sliding rod 210 is engaged with the first rack 330, the moving distance of the top end of the sliding rod 210 is smaller than the moving distance of the bottom end of the sliding rod 210. Figure 5 As shown, when subjected to the leftward airflow, the sliding rod 210 will move to the left, driving the mounting base 300 to move to the left as a whole. At the same time, the second rotating gear 214 at the upper end of the sliding rod 210 will rotate clockwise, causing the mounting base 300 to rotate counterclockwise, so that the mounting base 300 will be parallel to the base plate 100, and the overall leftward movement of the mounting base 300 will drive the half gear 320 thereon to move to the left, causing the first rotating gear 222 on the rotating rod 220 to rotate in the counterclockwise direction, thereby realizing the counterclockwise rotation of the two rotating rods 220, so that the two rotating rods 220 and the sliding rod 210 form a cone, and the sliding rod 210 at the rear of the tapered support rod group 200 can destroy the formed Karman vortex street effect, thereby avoiding the airflow from swirling at the sliding rod 210, so that the airflow is difficult to vibrate the support rod group 200, thereby improving the seismic resistance of a supporting structure of a monitoring device. At the same time, since the two support rods and the sliding rod 210 form a triangular support structure, on the one hand, the support stability is improved, and on the other hand, the distance between the camera 400 and the wall can be shortened, thereby reducing the impact of airflow on the mounting base 300.

[0041] When the sliding rod 210 needs to be reset, the reset motor is started to drive the reset gear 510 to rotate. When the sliding rod 210 needs to be reset to the right, the reset gear 510 is rotated counterclockwise, thereby driving the left sliding gear 540 to rotate clockwise, and the right sliding gear 520 to rotate clockwise. At this time, the right sliding gear 520 will only idle and will not slide along the right arc groove. While the left sliding gear 540 rotates clockwise, it will move along the left arc groove and compress the second spring 550 until the left sliding gear 540 is engaged with the second rack 131, so that the clockwise rotation of the left sliding gear 540 will move along the second rack 131 moves rightwards and drives the sliding rod 210 to move rightwards; when the sliding rod 210 needs to be reset to the left, the reset gear 510 rotates clockwise, thereby driving the right sliding gear 520 to rotate counterclockwise, and the left sliding gear 540 to rotate counterclockwise. At this time, the left sliding gear 540 will only idle and will not slide along the left arc groove. While the right sliding gear 520 rotates counterclockwise, it will move along the right arc groove and compress the third spring 530 until the right sliding gear 520 is engaged with the second rack 131. Thus, the counterclockwise rotation of the right sliding gear 520 will move leftwards along the second rack 131 and drive the sliding rod 210 to move leftwards. When the sliding rod 210 moves to the left or right, the rotating rod 220 will be driven to rotate and reset through the first transmission mechanism and the second transmission mechanism. When the sliding rod 210 moves to the position between the two rotating rods 220, the first spring 211 returns to the dead point position.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
