Description

Technical Field

[0001] This utility model relates to the field of monitoring and testing instruments, and in particular to a digital video monitoring and testing instrument suitable for high-definition network cameras. Background Technology

[0002] With the development of video compression technology, high-definition cameras, through more efficient H.265 compression, can transmit higher-definition images, such as 4K high-definition images, within the effective bandwidth. Security monitoring requires higher-definition images to discover every detail of the monitoring. For this reason, many important places will install higher-definition cameras. Moreover, with the maturity and development of technology, these high-definition cameras will be more widely used, and at the same time, monitoring test instruments will be needed to test them.

[0003] Existing monitoring and testing equipment can only be placed flat on a table when needed, which makes it inconvenient for staff to see the content displayed when the equipment is flat. When it needs to be placed at an angle, auxiliary tools are required, which is quite cumbersome.

[0004] Therefore, we propose a digital video surveillance tester suitable for high-definition network cameras. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a digital video surveillance tester suitable for high-definition network cameras, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A digital video monitoring tester suitable for high-definition network cameras, comprising a monitoring tester body, two side plates symmetrically fixedly installed on the back of the monitoring tester body, and connecting rods fixedly connected to the inner walls of the two side plates, a torsion spring sleeved on the outer edge of the connecting rod, a support plate rotatably connected to the outer edge of the connecting rod, a positioning strip fixedly installed on the side of the support plate near the monitoring tester body, a positioning hole opened in the inner wall of the positioning strip, a positioning block fixedly installed on the back of the monitoring tester body, a square groove opened on the side of the positioning block near the support plate, a receiving groove opened in the inner wall of the positioning block, a fixed plate fixedly installed on the inner wall of the receiving groove, one end of a spring fixedly connected to the outer side of the fixed plate, a movable plate fixedly connected to the other end of the spring, a pin slidably connected to the inner wall of the fixed plate, and a ramp opened at one end of the pin in the inner cavity of the square groove.

[0007] As a preferred embodiment of this utility model, a charging port is fixedly installed at the bottom of the monitoring and testing instrument body, and magnetic columns are symmetrically fixedly installed on the inner wall of the charging port.

[0008] By adopting the above technical solution, the charging port can be placed on the inner wall of the charging port, and then the magnetic column and the port can be connected by the magnetic attraction principle to achieve the positioning of the port, thereby eliminating the need for precise docking and improving the convenience of charging.

[0009] As a preferred embodiment of this utility model, the top of the monitoring and testing instrument body is threaded with a lifting ring, and a lifting rope is fixedly wound around the inner wall of the lifting ring.

[0010] By adopting the above technical solution, the device can be suspended using a rope, which improves the convenience of placement and makes it easier to store.

[0011] As a preferred technical solution of this utility model, the pin is fixedly connected to the inner wall of the movable disk, and a pull plate is fixedly connected to the end of the pin away from the slope. A through hole is opened on the outer side of the positioning block, and the through hole communicates with the receiving groove and the square groove. The pin is slidably connected to the inner wall of the through hole.

[0012] By adopting the above technical solution, the pull plate can drive the pin to drag the moving disk to move on the inner wall of the receiving groove, thereby realizing the movement of the pin near the slope end. The fixed plate can limit the end of the spring away from the moving disk to ensure that it will not rub against the inner wall of the receiving groove.

[0013] As a preferred embodiment of this utility model, the torsion spring is located in the middle of the support plate, one end of the torsion spring abuts against the back of the monitoring and testing instrument body, and the other end abuts against the side of the support plate near the positioning strip.

[0014] By adopting the above technical solution, when the end of the support plate away from the torsion spring is not positioned, the support plate can be pushed open by the force of the torsion spring. Thus, the support plate can be used to support the main body of the monitoring and testing instrument, which makes it easier to place the main body of the monitoring and testing instrument in an inclined state, and thus makes it easier to view the content displayed by the main body of the monitoring and testing instrument.

[0015] As a preferred technical solution of this utility model, the positioning strip is adapted to the shape of the inner wall of the square groove, and when the positioning strip is inserted into the inner wall of the square groove, the positioning hole corresponds to the position of the end of the pin near the slope.

[0016] By adopting the above technical solution, when the positioning strip is inserted into the inner wall of the square groove, the positioning strip will press the pin along the slope until the pin and the positioning hole are aligned. Then, the elastic restoring force of the spring can be used to insert the end of the pin near the slope into the inner wall of the positioning hole, thereby stably positioning the positioning strip in the inner wall of the square groove.

[0017] As a preferred embodiment of this utility model, a gripping groove is provided on the side of the support plate near the positioning block.

[0018] By adopting the above technical solution, it is convenient for users to carry the device to different locations and use it, thus improving the ease of handling.

[0019] The beneficial effects of this utility model are:

[0020] 1. The device can be carried to different locations by hand using the support plate and the grip slot. Pulling the pull plate can move the pin and the moving disc along the inner wall of the receiving slot, thereby moving the pin near the ramp end until the pin is disengaged from the inner wall of the positioning hole. Then the support plate can be rotated to the unfolded state with the help of the torsion spring. The support plate can support the monitoring and testing instrument body, making it easier to place the monitoring and testing instrument body in an inclined state and thus easier to view the content displayed by the monitoring and testing instrument body.

[0021] 2. By placing the charging socket on the inner wall of the charging port, the magnetic column and the socket can be connected using the magnetic attraction principle, thus achieving the positioning of the socket without the need for precise alignment, improving the convenience of charging.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 4 A digital video surveillance tester suitable for high-definition network cameras includes a tester body 1. Two side plates 6 are symmetrically fixedly installed on the back of the tester body 1, and connecting rods 7 are fixedly connected to the inner walls of the two side plates 6. A torsion spring 8 is sleeved on the outer edge of the connecting rod 7, and a support plate 9 is rotatably connected to the outer edge of the connecting rod 7. A positioning strip 10 is fixedly installed on the side of the support plate 9 near the tester body 1. A positioning hole 11 is opened on the inner wall of the positioning strip 10. A positioning block 12 is fixedly installed on the back of the tester body 1. A square groove 13 is opened on the side of the positioning block 12 near the support plate 9. A receiving groove 14 is opened on the inner wall of the positioning block 12. A fixed plate 15 is fixedly installed on the inner wall of the receiving groove 14. One end of a spring 16 is fixedly connected to the outer side of the fixed plate 15. A movable plate 17 is fixedly connected to the other end of the spring 16. A pin 18 is slidably connected to the inner wall of the fixed plate 15. A ramp 20 is opened at one end of the pin 18 in the inner cavity of the square groove 13.

[0029] Please see Figure 1 - Figure 3 The bottom of the monitoring and testing instrument body 1 is fixedly installed with a charging port 4. Magnetic columns 5 are symmetrically fixedly installed on the inner wall of the charging port 4, so that the charging plug can be placed on the inner wall of the charging port 4. Then, the magnetic column 5 and the plug can be connected by the magnetic attraction principle to realize the positioning of the plug, so that precise docking is not required and the convenience of charging is improved.

[0030] Please see Figure 1 - Figure 3 The top of the monitoring and testing instrument body 1 is threaded with a hanging ring 2, and a hanging rope 3 is fixedly wrapped around the inner wall of the hanging ring 2, so that the device can be suspended by the hanging rope 3, which improves the convenience of placement and makes it easier to store.

[0031] Please see Figure 4 The pin 18 is fixedly connected to the inner wall of the movable disk 17. The end of the pin 18 away from the slope 20 is fixedly connected to the pull plate 19. The outer side of the positioning block 12 is provided with a through hole, which communicates with the receiving groove 14 and the square groove 13. The pin 18 is slidably connected to the inner wall of the through hole, so that pulling the pull plate 19 can drive the pin 18 to drag the movable disk 17 to move on the inner wall of the receiving groove 14. This allows the pin 18 to move closer to the slope 20. The fixed disk 15 can limit the end of the spring 16 away from the movable disk 17 to ensure that it does not rub against the inner wall of the receiving groove 14.

[0032] Please see Figure 3The torsion spring 8 is located in the middle of the support plate 9. One end of the torsion spring 8 abuts against the back of the monitoring and testing instrument body 1, and the other end abuts against the side of the support plate 9 near the positioning strip 10. This allows the support plate 9 to be pushed open by the force of the torsion spring 8 when the end of the support plate 9 away from the torsion spring 8 is not positioned. This allows the support plate 9 to support the monitoring and testing instrument body 1, making it easier to place the monitoring and testing instrument body 1 in an inclined state and thus easier to view the content displayed by the monitoring and testing instrument body 1.

[0033] Please see Figure 3 The positioning strip 10 is adapted to the inner wall shape of the square groove 13. When the positioning strip 10 is inserted into the inner wall of the square groove 13, the positioning hole 11 corresponds to the end of the pin 18 near the slope 20. This allows the positioning strip 10 to press the pin 18 along the slope 20 when it is inserted into the inner wall of the square groove 13, until the pin 18 and the positioning hole 11 correspond. Then, the elastic restoring force of the spring 16 can be used to insert the end of the pin 18 near the slope 20 into the inner wall of the positioning hole 11, thereby stably positioning the positioning strip 10 on the inner wall of the square groove 13.

[0034] Please see Figure 2 and Figure 3 The support plate 9 has a grip groove on the side near the positioning block 12, which makes it easy for users to hold the device and use it in different locations, improving the convenience of picking it up.

[0035] Working principle: When using this device, first press the support plate 9 to insert the positioning strip 10 into the inner wall of the square groove 13. At this time, the positioning strip 10 will press the pin 18 along the slope 20 until the pin 18 and the positioning hole 11 are aligned. Then, with the elastic restoring force of the spring 16, the end of the pin 18 near the slope 20 is inserted into the inner wall of the positioning hole 11, thus stably positioning the positioning strip 10 on the inner wall of the square groove 13, thereby positioning the support plate 9. The user can then use the grip slot to hold the device and use it in different locations. When it is necessary to place the device, first pull the pull plate 19 to drag the pin 18. The movable disk 17 moves along the inner wall of the receiving groove 14, thereby moving the pin 18 to the end near the ramp 20 until the pin 18 disengages from the inner wall of the positioning hole 11. Then, the support plate 9 can be rotated to the unfolded state with the help of the torsion spring 8. The support plate 9 can then support the monitoring and testing instrument body 1, making it easier to place the monitoring and testing instrument body 1 in an inclined state and thus easier to view the content displayed on the monitoring and testing instrument body 1. At the same time, the charging port can be placed on the inner wall of the charging port 4, and the magnetic column 5 can be connected to the port using the magnetic attraction principle to achieve the positioning of the port, thus eliminating the need for precise docking and improving the convenience of charging.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
