Description

Technical Field

[0001] The utility model relates to the field of environmental monitoring technology, specifically a sealing device for a water quality analyzer. Background Technology

[0002] With the maturity of automation control technology and the exponential growth of demand for chemical analysis applications, online water quality analyzers came into being in the 1930s and 1940s. Water quality analyzers are mainly used to monitor the water quality of domestic water, sewage treatment, and industrial process control. The water quality analyzer includes a box body and various detection elements placed in the box body. The box body is provided with a power interface for electrical connection of various detection elements. The box body also includes a signal interface for signal transmission with external equipment. During the assembly process or use, the power cord or signal cord plug is directly inserted into the corresponding interface, and there is no sealing structure in the connection part between the interface and the plug. When the environment where the water quality analyzer is located is humid, external liquid will gradually penetrate into the connection part between the interface and the plug or into the box through the connection gap between the interface and the plug.

[0003] The existing device mainly adds multiple sealing rings on the inner wall of the socket to prevent water vapor from intruding. The existing technology is similar to a sealing device and analyzer for a water quality analyzer. The structure with patent number CN213145331U includes a sealing member arranged at the interface of the water quality analyzer case and a connecting member installed on the plug connector. The sealing member is provided with a through hole for the plug connector to pass through, and sealing rings are axially distributed along the inner wall of the through hole. At the same time, a fitting is arranged around the sealing member. The fitting and the sealing member enclose a groove. The connecting member is inserted into the groove when the plug connector is inserted into the interface, and the protruding part of the connecting member is snapped with the fitting. The sealing device of the utility model prevents external liquid from flowing axially into the interface and the plug connector connection along the gap between the plug connector and the through hole. At the same time, it is convenient to use the snap between the connecting part and the sealing member to prevent the plug connector from falling off. However, there are still areas that can be optimized in the device.

[0004] Existing devices mainly use a straight-tube plug-in structure, which makes it difficult for some devices to press and connect the sealing ring, resulting in gaps between some plugs and the sealing ring. At the same time, some cables are easily pulled by external forces, making it difficult for some devices to effectively buffer the external force pulling the cables, resulting in some plugs easily falling off, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a sealing device for a water quality analyzer is proposed. Contents of utility model

[0005] The purpose of the present utility model is to provide a sealing device for a water quality analyzer to solve the problems in the prior art mentioned in the above background technology. The existing devices mainly adopt a straight cylinder plug-in structure, making it difficult for some devices to press-fit and dock the sealing ring, resulting in gaps between some plugs and the sealing ring. At the same time, some cables are easily pulled by external forces, making it difficult for some devices to effectively buffer the external forces pulling the cables, and thus some plugs are prone to falling off.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A sealing device for a water quality analyzer, including a wiring table. Inside the upper part of the wiring table, there is a socket. A plug is inserted inside the right side of the socket. A cable is fixedly connected to the right side of the plug. A limit seat is fixedly connected to the lower right side of the wiring table.

[0007] A sealing mechanism is provided inside the socket. The sealing mechanism includes a screw cylinder. The left inner wall of the screw cylinder is movably connected to the outer wall of the socket. An anti-pulling mechanism is provided inside the limit seat. The anti-pulling mechanism includes a limit rod. Both ends of the limit rod are fixedly connected to the inner wall of the limit seat.

[0008] Preferably, a torsion ring is fixedly connected to the outer wall of the screw cylinder. A threaded ring is threadedly connected to the inner wall of the screw cylinder. The inner wall of the threaded ring is fixedly connected to the middle part of the outer wall of the plug.

[0009] Preferably, the right inner side of the socket is a frustum-shaped groove, and a sealing ring is fixedly connected to the right inner side of the socket.

[0010] Preferably, the left side of the plug is frustum-shaped, and the right side of the plug is hexagonal prism-shaped.

[0011] Preferably, a sliding sleeve is sleeved on the lower outer wall of the limit rod. A spring is fixedly connected to the outer ring of the top of the sliding sleeve on the limit rod. The top end of the spring is fixedly connected to the upper inner wall of the limit seat.

[0012] Preferably, a traction rod is movably connected to the right outer wall of the sliding sleeve. A clamping sleeve is movably connected to the top of the traction rod. The inner wall of the clamping sleeve is sleeved on the outer wall of the cable.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The utility model realizes the sealed docking of the plug through structures such as the screw cylinder, torsion ring, thread ring and sealing ring in the sealing mechanism. The plug is inserted into the right inner side of the socket, and the hexagonal prism position of the plug is held by hand. Then, the torsion ring is rotated clockwise to drive the screw cylinder to rotate in a limited way, so that the screw cylinder is threadedly sleeved on the outer wall of the thread ring. The thread ring drives the plug to slide leftward and press the sealing ring inside the socket, realizing the sealed docking of the plug. Some devices can press and dock the sealing ring, effectively avoiding the existence of gaps between the plug and the sealing ring, and improving the sealing performance and practicability of the device.

[0015] 2. The utility model realizes the anti-pulling of the cable through structures such as the limiting rod, sliding sleeve, spring, traction rod and clamping sleeve in the anti-pulling mechanism. The cable drives the clamping sleeve to move upward and rightward, and the top end of the traction rod synchronously slides with the clamping sleeve. The bottom end of the traction rod drives the sliding sleeve to slide upward on the outer wall of the limiting rod, so that the sliding sleeve presses the spring, thereby weakening the force on the plug, realizing the anti-pulling of the cable. Some devices can effectively buffer the external force of pulling the cable, thus avoiding the plug from falling off, and improving the stability and practicability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0023] A sealing device for a water quality analyzer, including a wiring platform 11. Inside the upper part of the wiring platform 11, there is a socket 12. Inside the right side of the socket 12, a plug 13 is inserted. The right side of the plug 13 is fixedly connected with a cable 14. The lower right side of the wiring platform 11 is fixedly connected with a limit seat 15;

[0024] Inside the socket 12, there is a sealing mechanism 2. The sealing mechanism 2 includes a screw cylinder 21. The left inner wall of the screw cylinder 21 is movably connected to the outer wall of the socket 12. The outer wall of the screw cylinder 21 is fixedly connected with a torsion ring 22. The inner wall of the screw cylinder 21 is threadedly connected with a threaded ring 23. The inner wall of the threaded ring 23 is fixedly connected to the middle part of the outer wall of the plug 13. Through this design, it is realized that the torsion ring 22 drives the screw cylinder 21 to rotate in a limited way, so that the screw cylinder 21 can be sleeved on the outer wall of the threaded ring 23, which is convenient for the socket 12 and the plug 13 to be fixedly docked. The right inner side of the socket 12 is a frustum-shaped groove, and the right inner side of the socket 12 is fixedly connected with a sealing ring 24. Through this design, it is realized that the socket 12 and the plug 13 cooperate to press the sealing ring 24. The left side of the plug 13 is frustum-shaped, and the right side of the plug 13 is hexagonal prism-shaped. Through this design, it is realized that by holding it by hand, the stability of the plug 13 can be maintained, and the screw cylinder 21 is prevented from driving the threaded ring 23 and the plug 13 to rotate.

[0025] Inside the limit seat 15, there is an anti-pulling mechanism 3. The anti-pulling mechanism 3 includes a limit rod 31. Both ends of the limit rod 31 are fixedly connected to the inner wall of the limit seat 15. A sliding sleeve 32 is sleeved on the lower part of the outer wall of the limit rod 31. Above the sliding sleeve 32, a spring 33 is fixedly connected to the outer ring of the limit rod 31. The top end of the spring 33 is fixedly connected to the upper part of the inner wall of the limit seat 15. Through this design, it is realized that the sliding sleeve 32 slides on the outer wall of the limit rod 31 and stretches the spring 33. The right side of the outer wall of the sliding sleeve 32 is movably connected with a traction rod 34. The top of the traction rod 34 is movably connected with a clamping sleeve 35. The inner wall of the clamping sleeve 35 is sleeved on the outer wall of the cable 14. Through this design, it is realized that the clamping sleeve 35 can drive the traction rod 34 to move in the direction close to the socket 12.

[0026] Working principle: When it is necessary to seal and dock the plug 13, first insert the plug 13 into the right side inside the socket 12, and hold the hexagonal prism-shaped position of the plug 13 by hand. Then rotate the torsion ring 22 clockwise. The torsion ring 22 drives the screw cylinder 21 to rotate in a limited way, so that the screw cylinder 21 is threadedly sleeved on the outer wall of the threaded ring 23. The threaded ring 23 drives the plug 13 to slide to the left, so that the plug 13 presses the sealing ring 24 inside the socket 12, realizing the sealing docking operation of the plug 13.

[0027] When it is necessary to prevent the cable 14 from being pulled, first, the cable 14 drives the ferrule 35 to move upward and rightward. The ferrule 35 drives the top end of the traction rod 34 to slide synchronously. The bottom end of the traction rod 34 drives the sliding sleeve 32 to slide upward on the outer wall of the limiting rod 31, so that the sliding sleeve 32 presses the spring 33, thereby reducing the force on the plug 13, realizing the operation of preventing the cable 14 from being pulled, and the operation ends here.

[0028] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any ordinary technician in the industry can smoothly implement the present invention according to the drawings shown in the specification and the above. However, any minor changes, modifications and equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
