[0001] The present invention relates to the technical field of monitoring equipment sealing, and in particular to a sealing and waterproof device and monitoring equipment. Background Art

[0002] In recent years, with the rapid development of computers, networks, image processing and transmission technology, video surveillance technology has also developed very well. Now video surveillance has been widely used in various fields. Video surveillance is an important part of the security system. It is a comprehensive system with strong prevention capabilities. Monitoring equipment is currently often used in outdoor environments and needs to have waterproof performance.

[0003] In the prior art, after the tail wire of the monitoring equipment is passed through the shell, the gap between the tail wire and the shell is sealed by applying glue. Although the IP67 waterproof performance can be achieved, the glue for the tail wire of the monitoring equipment is relatively expensive, and it needs to be baked for more than 1 hour after applying the glue, which is a waste of work time. Another way is to set a sealing ring structure between the tail wire and the shell to achieve waterproofing. However, the waterproof sealing ring is easily aged when exposed to the air, resulting in a shortened lifespan, and its waterproof grade is low.

[0004] Based on this, there is an urgent need for a sealing and waterproof device and a monitoring device to solve the above-mentioned problems. Summary of the invention

[0005] Based on the above, the purpose of the present invention is to provide a sealing and waterproof device and a monitoring device, which improves the waterproof level of the tail line of the monitoring equipment from IP66 to IP67; increases the safety of equipment use, improves the service life of the equipment, saves production costs, and reduces production time.

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0042] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0044] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] In the prior art, after the tail wire of the monitoring equipment is passed through the shell, the gap between the tail wire and the shell is sealed by applying glue. Although the IP67 waterproof performance can be achieved, the glue for the tail wire of the monitoring equipment is relatively expensive, and it needs to be baked for more than 1 hour after applying the glue, which is a waste of work time. Another way is to set a sealing ring structure between the tail wire and the shell to achieve waterproofing. However, the waterproof sealing ring is easily aged when exposed to the air, resulting in a shortened lifespan, and its waterproof grade is low.

[0046] To solve the above problems, Figure 1-Figure 5 As shown, the present invention provides a monitoring device, which includes a sealing and waterproof device, and the sealing and waterproof device includes a housing 1, a first sealing component 2, a second sealing component 3 and a driving member.

[0047] Specifically, Figure 1 and Figure 2 The side wall of the housing 1 is provided with a threading portion 11, and one end of the threading portion 11 away from the chamber of the housing 1 is provided with a first mounting hole 112, and the other end is provided with a second mounting hole 113, and a first threading hole 111 is provided between the first mounting hole 112 and the second mounting hole 113. The first sealing component 2 is installed in the first mounting hole 112, and the second sealing component 3 is installed in the second mounting hole 113; the driving member is installed in the chamber of the housing 1 and connected to the second sealing component 3, and the driving member can drive the second sealing component 3 to be installed in the second mounting hole 113.

[0048] The tail line 100 is sequentially passed through the first sealing component 2, the first threading hole 111 and the second sealing component 3. The first sealing component 2 and the second sealing component 3 seal the two ends of the first threading hole 111 respectively. The two-layer sealing structure solves the technical problem of poor mechanical sealing and waterproofing effect of the tail line 100, and improves the waterproof level of the tail line 100 of the monitoring equipment from IP66 to IP67. Moreover, when the service life of the first sealing component 2 expires, the second sealing component 3 can still play a sealing role to prevent the sealing from failing and causing damage to the equipment. The staff has sufficient time to inspect and replace the first sealing component 2, which increases the safety of the equipment and improves the service life of the equipment. Furthermore, the present invention does not use the dispensing method for sealing, which not only saves production costs, but also reduces production time.

[0049] More specifically, the first sealing assembly 2 includes a first conical sealing ring 21 and a first abutting member 22. The first conical sealing ring 21 is located at one end of the first threading hole 111 away from the chamber, and the small end of the first conical sealing ring 21 is installed between the tail wire 100 and the first threading hole 111. The first mounting hole 112 is a threaded hole, such as Figure 3 As shown, the side wall of one end of the first abutting member 22 is provided with an external thread matching the threaded hole, the first abutting member 22 is threadedly connected to the first mounting hole 112, and the other end of the first abutting member 22 is provided with a clamping portion 223. The operator can clamp and twist the clamping portion 223 with a wrench or an electric tool, so that the first abutting member 22 is tightened and fixed in the first mounting hole 112 and abuts against the large end of the first conical sealing ring 21. The first conical sealing ring 21 is compressed and deformed under the action of the first abutting member 22, so that the first threading hole 111 and the tail line 100 are interference-fitted to form a primary sealing structure.

[0050] Preferably, the end surface of the first abutting member 22 abutting against one end of the first conical sealing ring 21 is further provided with a first positioning groove 222, and the large end of the first conical sealing ring 21 abuts against the first positioning groove 222. On the one hand, the first positioning groove 222 can assemble and position the first conical sealing ring 21 to increase the convenience of assembly, and on the other hand, prevent the large end of the first conical sealing ring 21 from being displaced during the compression process, causing damage to the first conical sealing ring 21. A second threading hole 221 is passed through the center of the first abutting member 22, and the second threading hole 221 is connected to the first positioning groove 222, and the tail wire 100 can be passed through the second threading hole 221 and the first positioning groove 222.

[0051] More specifically, the second sealing assembly 3 includes a second conical sealing ring 31 and a second abutting member 32. The second conical sealing ring 31 is located at one end of the threading hole close to the chamber, and the small end of the second conical sealing ring 31 is installed between the tail line 100 and the threading hole. The second mounting hole 113 is a threaded hole, and the side wall at one end of the second abutting member 32 is provided with an external thread matching the internal threaded hole of the second mounting hole 113. The second abutting member 32 is threadedly connected to the second mounting hole 113, and a connecting portion is provided at the other end. The connecting portion is connected to the driving member, and the driving member can drive the second abutting member 32 to rotate, so that the second abutting member 32 is tightened to the second mounting hole 113 and abuts against the large end of the second conical sealing ring 31. The second conical sealing ring 31 is compressed and deformed under the action of the second abutting member 32, so that the first threading hole 111 and the tail line 100 are interference-fitted to form a secondary sealing structure.

[0052] Preferably, if Figure 4 As shown, in this embodiment, the driving member is preferably a motor 4, and a rotation key 42 is provided on the output shaft 41 of the motor 4. The connecting portion of the second abutting member 32 is a connecting hole 321 with a slide groove 322 on the side wall. The connecting hole 321 is sleeved on one end of the output shaft 41, and the rotation key 42 is slidably connected in the slide groove 322. When the output shaft 41 rotates, the rotation key 42 drives the second abutting member 32 to rotate, so that the external thread of the second abutting member 32 is threadedly connected to the second mounting hole 113. In addition, since the rotation key 42 and the slide groove 322 are slidably connected, the second abutting member 32 can move away from the motor 4 through the slide groove 322 structure, and at the same time be tightened in the second mounting hole 113, so that the fixed connection of the second abutting member 32 is achieved. The output shaft 41 gives the second abutting member 32 a force to rotate, and does not restrict its axial movement. When the service life of the first conical sealing ring 21 expires or is corroded and damaged, in typhoon weather, water vapor will pass through the first conical sealing ring 21 and impact the second conical sealing ring 31. At this time, the motor 4 can give a rotational force to the second abutting member 32, so that the second abutting member 32 is always tightened in the second mounting hole 113 and abuts against the second conical sealing ring 31, preventing sealing failure caused by loose threads and increasing the service life of the device.

[0053] More preferably, if Figure 5 As shown, the end surface of the second abutting member 32 abutting against one end of the second conical sealing ring 31 is also provided with a second positioning groove 323, and the large end of the second conical sealing ring 31 abuts against the second positioning groove 323. On the one hand, the second positioning groove 323 can assemble and position the second conical sealing ring 31 to increase the convenience of assembly, and on the other hand, prevent the large end of the second conical sealing ring 31 from being displaced during the compression process, causing damage to the second conical sealing ring 31.

[0054] The second supporting member 32 is also provided with a third threading hole 324, and the wire inlet of the third threading hole 324 is arranged at the bottom of the second positioning groove 323. Since a connecting hole 321 is arranged on the end face of the second supporting member 32 close to the end of the motor 4, the wire outlet of the third threading hole 324 is located on the side wall of the second supporting member 32 and will not interfere with the position of the connecting hole 321. The tail line 100 can be passed through the second positioning groove 323, the wire inlet of the third threading hole 324 and the wire outlet of the third threading hole 324.

[0055] Preferably, the first conical sealing ring 21 and the second conical sealing ring 31 are made of silicone, which increases the interference fit between the tail wire 100 and the first threading hole 111 and improves the sealing performance.

[0056] It should be noted that the installation steps of the sealing and waterproof device in this embodiment are as follows:

[0057] Step 1: Pass the tail wire 100 through the first supporting member 22, the first conical sealing ring 21 and the threading portion 11 in sequence;

[0058] Step 2: Install the large end of the first conical sealing ring 21 into the first positioning groove 222 of the first abutting member 22, and use an electric tool to thread the first abutting member 22 into the first mounting hole 112. After tightening, the first conical sealing ring 21 is compressed to make the tail wire 100 and the first threading hole 111 have an interference fit to form a primary sealing structure;

[0059] Step 3: Pass the tail wire 100 through the second conical sealing ring 31 and the second abutting member 32 at one time, pass through the side surface of the second abutting member 32 and connect to the circuit board 200 of the monitoring device;

[0060] Step 4: Install the second conical sealing ring 31 into the second positioning groove 323 of the second holding member 32. Then insert the output shaft 41 of the motor 4 into the connecting hole 321 of the second holding member 32. The motor 4 is fixed in the chamber of the housing 1, and the motor 4 is electrically connected to the circuit board 200 of the monitoring device. The program of the circuit board 200 controls the motor 4 to tighten the second holding member 32 into the second mounting hole 113. After tightening, the second conical sealing ring 31 is compressed so that the tail wire 100 and the first threading hole 111 are interference-fitted to form a secondary sealing structure.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
