Description

Technical Field

[0001] This utility model relates to the field of dissolved oxygen meter technology, and more specifically, to a portable replaceable dissolved oxygen meter probe structure. Background Technology

[0002] A dissolved oxygen meter is a device that can detect the oxygen content in water. Existing dissolved oxygen meter probes usually consist of two parts: the upper end of the probe is connected to the instrument's wires, and the lower end of the probe is mainly used for liquid detection. The upper and lower ends of the dissolved oxygen meter probe are connected by screws, which makes it inconvenient to quickly position and clamp the dissolved oxygen meter probe, making it relatively inconvenient to use.

[0003] To address the aforementioned issues, patent document publication number CN218995230U discloses a dissolved oxygen meter probe structure that facilitates positioning and mounting, comprising a device body; a display screen is provided on the outer side of the device body, a connecting line is fixedly mounted on the upper end of the device body, an installation head is provided at one end of the connecting line, a connecting tube is provided at the bottom end of the installation head, and a mounting component is provided on the outer side of the connecting tube.

[0004] However, it still has some drawbacks in actual use, such as: the connection between the metal insert of the probe and the connecting pipe does not mention a corresponding sealing structure, and liquid may seep in through the connection, causing short circuits or corrosion, affecting electrical stability. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a portable replaceable dissolved oxygen meter probe structure to solve the problem that the prior art does not mention a corresponding sealing structure at the connection between the metal insert and the connecting pipe, which may allow liquid to seep in through the connection, leading to short circuits or corrosion.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a portable replaceable dissolved oxygen meter probe structure, including a device body, a connecting wire provided on the top of the device body, an installation head fixedly connected to one end of the connecting wire relative to the device body, a metal insert provided at the bottom of the installation head, and the portable replaceable dissolved oxygen meter probe structure further includes...

[0007] Insert plates are arranged opposite each other on both sides of the bottom surface of the mounting head, and the insert plates are configured as hollow structures;

[0008] The connector has a probe body fixedly installed at its bottom end;

[0009] The insert slot has an insert slot and a plug slot respectively opened at the center and side of the top of the connecting tube. The interior of the insert slot is inserted into the surface of the metal insert, and the interior of the plug slot is in contact with the surface of the insert plate.

[0010] The fixing grooves are formed on opposite sides of the connecting pipe surface;

[0011] A sealing gasket is disposed at the top edge of the connector tube, and the surface of the sealing gasket is in contact with the bottom edge of the mounting head.

[0012] It also includes a guide post, a spring, and an arc-shaped locking block. The guide post is fixedly installed inside the insert plate and is designed as a hollow structure. One end of the spring is fixedly connected to the inner cavity of the guide post, and the other end of the spring is fixedly connected to the inside of the arc-shaped locking block. The surface of the guide post is slidably connected to the inner wall of the arc-shaped locking block, and the surface of the arc-shaped locking block is in contact with the inside of the fixing groove.

[0013] The device includes a socket cover, a bottom ring, a mounting ring, a second sealing gasket, and a pushing block. The bottom ring is located at the bottom of the socket cover, and the mounting ring is fixedly installed on the periphery of the connecting pipe. The surface of the bottom ring is roughened, and the surface of the bottom ring is rotatably connected to the inner wall of the mounting ring. The second sealing gasket is located at the top of the socket cover, and the inner ring of the second sealing gasket is in contact with the outer wall of the mounting head. The pushing block is slidably installed on the surface of the socket cover, and one side of the pushing block is in contact with the surface of the arc-shaped locking block.

[0014] It also includes an annular receiving groove, which is formed on the inner wall of the sleeve cover.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, the mounting head and the connector are plugged in, allowing the metal insert to be inserted into the insert slot. The insert plates on both sides of the bottom of the mounting head enter the insertion slot. At this time, the arc-shaped locking block at the bottom of the insert plate contacts the inner wall of the insertion slot and is squeezed. The spring connected inside the guide column deforms, and the arc-shaped locking block retracts into the insert plate. When the mounting head and the connector are plugged in and closed, the arc-shaped locking block moves down to the position of the fixing slot and moves horizontally under the elastic action of the spring, locking with the fixing slot. This completes the locking and positioning of the probe body. By changing the locking structure such as the insert plate from the outside of the mounting head and the connector to the inside, the probe is made simpler overall. The top locking can integrate an annular sealing ring, which presses the sealing gasket one simultaneously when the buckle is closed to prevent liquid from seeping into the probe circuit and ensure stable electrical connection.

[0017] When it is necessary to separate the mounting head and the connector, rotate the sleeve cover to align the push block with the arc-shaped locking block horizontally. Then, press the arc-shaped locking block inward to retract it into the insert plate, thereby disengaging it from the fixing groove. Then, move the mounting head up to separate it from the connector, completing the disassembly of the probe body. In addition, after the mounting head and the connector are connected, the sleeve cover can be rotated to move the bottom ring away from the position flush with the arc-shaped locking block, preventing the bottom ring from accidentally moving after the mounting head and connector are connected, which would affect the stability of the arc-shaped locking block.

Detailed Implementation

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To be continued Figure 4 This utility model provides a portable replaceable dissolved oxygen meter probe structure, including a device body 1, a connecting wire 2 on the top of the device body 1, a mounting head 3 fixedly connected to one end of the connecting wire 2 relative to the device body 1, and a metal insert 4 at the bottom of the mounting head 3. The portable replaceable dissolved oxygen meter probe structure also includes...

[0026] Insert plate 5 is arranged on both sides of the bottom surface of mounting head 3, and the insert plate 5 is set as a hollow structure;

[0027] Connector 6, with probe body 20 fixedly installed at the bottom end of connector 6;

[0028] Insertion slot 7 and insertion groove 8 are respectively provided at the center and side of the top of the connecting tube 6. The interior of the insertion slot 7 is inserted into the surface of the metal insert 4, and the interior of the insertion groove 8 is in contact with the surface of the insert plate 5.

[0029] Fixing grooves 9 are formed on both sides of the surface of the connecting pipe 6;

[0030] Sealing gasket 10 is located on the top edge of the connector 6. The surface of sealing gasket 10 fits against the bottom edge of the mounting head 3. By setting sealing gasket 10 on the top of connector 6, sealing gasket 10 can be pressed together when connector 6 is connected to mounting head 3 to seal the connection between mounting head 3 and connector 6, preventing liquid from seeping in and causing short circuit or corrosion to metal insert 4.

[0031] The system also includes a guide post 11, a spring 12, and an arc-shaped locking block 13. The guide post 11 is fixedly installed inside the insert plate 5 and is designed as a hollow structure. One end of the spring 12 is fixedly connected to the inner cavity of the guide post 11, and the other end of the spring 12 is fixedly connected to the inside of the arc-shaped locking block 13. The surface of the guide post 11 is slidably connected to the inner wall of the arc-shaped locking block 13, and the surface of the arc-shaped locking block 13 is in contact with the inside of the fixing groove 9. The slidable connection between the guide post 11 and the arc-shaped locking block 13 prevents the arc-shaped locking block 13 from separating from the guide post 11 under the elastic push of the spring 12, thus preventing it from retracting and resetting.

[0032] The assembly includes a socket cover 14, a bottom ring 15, a mounting ring 16, a second sealing gasket 17, and a push block 18. The bottom ring 15 is located at the bottom of the socket cover 14, and the mounting ring 16 is fixedly installed on the periphery of the connecting pipe 6. The surface of the bottom ring 15 is roughened, and the surface of the bottom ring 15 is rotatably connected to the inner wall of the mounting ring 16. The second sealing gasket 17 is located at the top of the socket cover 14, and the inner ring of the second sealing gasket 17 is in contact with the outer wall of the mounting head 3. The push block 18 is slidably installed on the surface of the socket cover 14, and one side of the push block 18 contacts the surface of the arc-shaped locking block 13. Through the bottom ring 15, its roughened structure can generate a large friction force when it contacts the inner wall of the mounting ring 16. Thus, the friction force can fix the rotating socket cover 14 in a certain position, preventing the push block 18 from accidentally contacting the arc-shaped locking block 13 due to accidental rotation of the socket cover 14, which would affect the stable connection between the mounting head 3 and the connecting pipe 6.

[0033] It also includes an annular receiving groove 19, which is formed on the inner wall of the socket cover 14. The annular receiving groove 19 provides space in the inner wall of the socket cover 14 to accommodate the arc-shaped locking block 13, so as to avoid the socket cover 14 being obstructed by the part of the arc-shaped locking block 13 protruding from the fixing groove 9 when it rotates.

[0034] The working process of this utility model is as follows: The mounting head 3 is inserted into the connecting tube 6 so that the metal insert 4 can be inserted into the insert slot 7, and the insert plates 5 set on both sides of the bottom of the mounting head 3 enter the insertion slot 8. At this time, the arc-shaped locking block 13 set at the bottom of the insert plate 5 contacts the inner wall of the insertion slot 8 and is squeezed. The spring 12 connected inside the guide post 11 deforms, and the arc-shaped locking block 13 retracts into the insert plate 5. When the mounting head 3 and the connecting tube 6 are inserted and closed, the arc-shaped locking block 13 moves down to the position of the fixing slot 9 and moves horizontally under the elastic action of the spring 12, locking with the fixing slot 9, thus completing the locking and positioning of the probe body 20.
