Description

Technical Field

[0001] This utility model relates to the field of camera connector equipment technology, and in particular to a sealing sleeve for a video camera connector. Background Technology

[0002] A video camera is a device that captures images or video signals and transmits them to another location for users to view or record in real time. A camera connector is an interface or connector that connects the camera to other devices, such as USB, HDMI, and AV connectors. These connectors require waterproofing, especially in outdoor or diving environments. To prevent moisture and impurities from entering the connector, a sealing device is used. These sealing devices help protect the camera connector from leaks and damage. Currently, assessing the internal sealing condition of camera connector seals often relies on specialized equipment such as airtightness testing instruments, which is time-consuming and labor-intensive. Even if the exterior appears intact, hidden dangers may exist, such as aging and undeformed sealing rings, making it easy for maintenance personnel to misjudge the sealing performance. This can lead to sudden malfunctions due to seal failure in extreme environments such as heavy rain and dust, severely impacting the reliability and stability of the monitoring system and making it difficult to meet the needs of real-time and accurate security monitoring. Utility Model Content

[0003] The purpose of this invention is to address the problems of current camera connector sealing devices requiring specialized equipment to inspect the internal seal, which is time-consuming and labor-intensive, and the potential for aging of the sealing ring even when the appearance is intact. Furthermore, these devices are prone to failure due to seal failure in extreme environments, affecting the reliability of monitoring. The invention proposes a sealing sleeve for video camera connectors.

[0004] The technical solution of this utility model is as follows: A sealing sleeve for a video camera connector, comprising a main cylinder and a first connector and a second connector that are interlocked with each other. Both the first and second connectors are provided with connecting wires. The device also includes: a sealing mechanism disposed at both ends of the main cylinder to prevent moisture from entering the connection between the first and second connectors; the main cylinder is made of transparent acrylic; the sealing mechanism includes threaded tilting heads fixedly connected to both ends of the main cylinder; each threaded tilting head has a plurality of tightening claws arranged in a circular array fixedly connected to its end away from the main cylinder; the connecting wires of the first and second connectors are covered with sealing blocks that are inserted into the threaded tilting heads; a testing mechanism installed inside the main cylinder for detecting and visually observing the humidity inside the main cylinder; and an anti-reverse mechanism slidably sleeved at both ends of the main cylinder to prevent the sealing mechanism from reversing.

[0005] Optionally, the sealing block is made of silicone, and the threaded tilting head is provided with a spiral sleeve that abuts against the tightening claw and contracts inward to clamp the sealing block.

[0006] Optionally, the end of the threaded tilting head near the main cylinder is fixedly connected with a retaining ring that locks the sealing block into the main cylinder.

[0007] Optionally, the anti-reverse mechanism includes an installation groove on the main cylinder, a return spring fixedly connected inside the installation groove, sliding sleeve blocks slidably fitted at both ends of the main cylinder, sliding locking blocks for sliding into the installation groove fixedly connected to the inner wall of the sliding sleeve blocks, protrusions fixedly connected to the sliding locking blocks, and multiple locking holes arranged in a circumferential array at one end of the spiral sleeve near the main cylinder for being locked into by the protrusions.

[0008] Optionally, the testing mechanism includes a first connection port and a second connection port opened inside the main cylinder. Both the first connection port and the second connection port are spirally connected with sealing plugs. One sealing plug has an acid-base test paper attached to its end, and the other sealing plug has a humidity test paper attached to its end.

[0009] Optionally, the outer wall of the spiral sleeve is provided with a plurality of strip-shaped protrusions arranged in a circumferential array to increase the friction when the hand contacts it.

[0010] Optionally, the outer wall of the sliding sleeve is provided with multiple anti-slip textures arranged in a linear pattern to prevent the hand from sliding when moving the sliding sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This invention utilizes a combination of components including a main cylinder, a testing mechanism, a sealing mechanism, and an anti-reverse mechanism. During use, the transparent acrylic main cylinder allows direct observation of the joint position. The testing mechanism uses humidity and pH test strips to monitor the humidity and pH levels inside the main cylinder in real time. The sealing mechanism, through a spiral sleeve driving a tightening claw, clamps the sealing block and, combined with a retaining ring, achieves multiple seals. The anti-reverse mechanism uses a return spring to push a protrusion into a locking hole to lock the spiral sleeve. This approach integrates visual design, real-time monitoring, and mechanical locking into a unified system, reducing reliance on specialized equipment, optimizing maintenance processes, enhancing hazard prediction and reliability in extreme environments, and improving the stability of the monitoring system.

[0024] Example

[0025] like Figures 1-4 As shown, the present invention proposes a sealing sleeve for a video camera connector, comprising a main cylinder 1 and a first connector 11 and a second connector 12 that are interlocked with each other. Both the first connector 11 and the second connector 12 are provided with connecting wires 15. The device also includes: a sealing mechanism disposed at both ends of the main cylinder 1 to prevent moisture from entering the connection between the first connector 11 and the second connector 12; the main cylinder 1 is made of transparent acrylic; a testing mechanism installed inside the main cylinder 1 for detecting the humidity inside the main cylinder 1 and visually observing it; and an anti-reverse mechanism that is slidably sleeved at both ends of the main cylinder 1 to prevent the sealing mechanism from running in reverse.

[0026] In one embodiment, the sealing mechanism includes threaded tilting heads 2 fixedly connected to both ends of the main cylinder 1. Each threaded tilting head 2 near the main cylinder 1 has a retaining ring 22 fixedly connected to it, which holds the sealing block 4 and slides it into the main cylinder 1. Each threaded tilting head 2 away from the main cylinder 1 has several tightening claws 21 arranged in a circular array fixedly connected to it. The connecting line 15 of the first connector 11 and the second connector 12 is covered with a sealing block 4 that is inserted into the threaded tilting head 2. The sealing block 4 is made of silicone, which typically has good sealing performance and resistance to high temperatures and chemical corrosion, making it suitable for sealing connectors to prevent external substances such as moisture and dust from entering the internal equipment. A spiral sleeve 3 is helically fitted onto the threaded tilting head 2, which abuts against the tightening claws 21 and contracts inward to clamp the sealing block 4. The outer wall of the spiral sleeve 3 has several strip-shaped protrusions arranged in a circular array to increase friction when in contact with the hand.

[0027] In one embodiment, the anti-reverse mechanism includes a mounting groove 16 formed on the main cylinder 1. A return spring 17 is fixedly connected inside the mounting groove 16. The function of the return spring 17 is to ensure that the sliding sleeve 5, under normal conditions, drives the sliding block 51 and the protrusion 52 on it to be continuously engaged in the locking hole 31 on the spiral sleeve 3. Sliding sleeves 5 are slidably mounted on both ends of the main cylinder 1. The outer wall of the sliding sleeve 5 is provided with several anti-slip textures arranged in a linear pattern to prevent the sliding sleeve 5 from sliding when the hand moves. The inner wall of the sliding sleeve 5 is fixedly connected with a sliding block 51 for sliding in the mounting groove 16. A protrusion 52 is fixedly connected on the sliding block 51. The spiral sleeve 3 near the end of the main cylinder 1 is provided with several locking holes 31 arranged in a circumferential array for being engaged by the protrusion 52.

[0028] Furthermore, the testing mechanism includes a first connection port 13 and a second connection port 14 located within the main cylinder 1. Both the first and second connection ports 13 and 14 are internally connected by a spirally screwed sealing stopper 1341. One of the sealing stoppers 1341 has an acid-base test paper 1342 attached to its end. The acid-base test paper 1342 contains an acid-base indicator (such as litmus). If acidic or alkaline gases (such as HCl or NH3) are present in the air, the moisture dissolved on the test paper will change the indicator structure, resulting in color change. By comparing with a standard color chart, the acidity or alkalinity of the air can be determined. The other sealing stopper 1341 has a humidity test paper 1343 attached to its end. The humidity test paper 1343 contains a hygroscopic color-developing substance (such as cobalt chloride or anhydrous copper sulfate). When exposed to air, it will absorb moisture and undergo a physical or chemical reaction, resulting in a color change (e.g., cobalt chloride changes from blue to pink). By comparing with a standard color chart, the range of relative humidity in the air can be determined, thus achieving humidity detection.

[0029] In this embodiment, when using the sealing sleeve of the video camera connector, firstly, humidity test paper 1343 and acid / alkali test paper 1342 are inserted into the corresponding sealing plug 1341, and then the sealing plug 1341 is screwed into the corresponding first connection port 13 and second connection port 14; while the first connector 11 and the second connector 12 are fitted with covering sealing blocks 4. Next, one end of the second connector 12 is passed sequentially through the spiral sleeve 3 and the threaded tilting head 2 at one end of the main cylinder 1, and then through the threaded tilting head 2 and the spiral sleeve 3 at the other end of the main cylinder 1, to complete the connection with the first connector 11. Afterwards, the connected first connector 11 and second connector 12 are moved into the main cylinder 1, and the position is visually observed using the acrylic material of the main cylinder 1 to ensure that the connection point is located in the middle of the main cylinder 1. Then, the sealing block 4 is inserted into the tightening claw 21. The spiral sleeves 3 at both ends of the main cylinder 1 are spirally connected to the threaded tilting head 2, causing them to move towards the main cylinder 1, which drives the tightening claw 21 to clamp the sealing block 4. The retaining ring 22 simultaneously squeezes the sealing block 4, making it fit tightly against the inner wall of the threaded tilting head 2 and the retaining ring, with both ends pressing against each other to prevent water seepage. Finally, when the spiral sleeve 3 moves, it first abuts against the protrusion 52 of the sliding sleeve block 5, pushing it to slide along the mounting groove 16. After reaching the end of the main cylinder 1, the return spring 17 pushes the sliding retaining block 51, causing the protrusion 52 to engage with the retaining hole 31 of the spiral sleeve 3, locking its position. When disassembling, sliding the sliding sleeve block 5 causes the protrusion 52 to disengage from the retaining hole 31, and the spiral sleeve 3 can be rotated again.
