Detailed Embodiment

[0019] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] As shown in Figures 1-5As shown in the figure, an electrochemical cell tester of the present utility model includes a tester body 1. Circular grooves 10 are provided on the left and right side walls of the tester body 1. Concentrically fixed in the two circular grooves 10 are circular shafts 11. In the two circular grooves 10, wire wheels 12 matching the circular shafts 11 are concentrically and rotationally assembled. Fixed between the inner walls of the two wire wheels 12 and the side walls of the circular shafts 11 are torsion springs 13. The two wire wheels 12 are each wound with a pulling rope 14. One end of each of the two pulling ropes 14 is fixedly connected to the side wall of the wire wheel 12, and the other end of each of the two pulling ropes 14 is fixedly provided with a square block 15. The two wire wheels 12 are each wound with a detection wire 16. The two square blocks 15 are each provided with an insertion hole 17 matching the detection wire 16. On the front side of the tester body 1, two inclined grooves 18 communicating with the circular grooves 10 are provided. In the two inclined grooves 18, limiting components matching the square blocks 15 are provided;

[0021] When the present utility model is not in use, under the elastic force of the torsion spring 13, the wire wheel 12 winds up both the pulling rope 14 and the detection wire 16 on the side wall of the wire wheel 12. The plug end of the detection wire 16 is inserted into the insertion hole 17 of the square block 15, connecting the detection wire 16 to the pulling rope 14 and winding the detection wire 16 into the wire wheel 12, avoiding the loss of the detection wire 16 and facilitating storage;

[0022] When the present utility model is in use, the user directly pulls the detection wire 16 away from the tester body 1. During the process of pulling out the detection wire 16, the detection wire 16 drives the wire wheel 12 to rotate, winding up the torsion spring 13. After the detection wire 16 is completely taken out, the other end of the detection wire 16 drives the pulling rope 14 and the square block 15 to slide out of the inclined groove 18. The user controls the limiting component to limit the square block 5, and then separates the plug end of the detection wire 16 from the square block 15. The structure is simple and the use is convenient;

[0023] During the use of the present utility model, when the detection wire 16 needs to be stored, the user directly inserts the plug end of the detection wire 16 into the insertion hole of the square block 15, connecting the detection wire 16 to the square block 15. Then, the user controls the limiting component to release the limit on the square block 15. Under the winding action of the torsion spring 13, the wire wheel 12 is driven to rotate, winding the pulling rope 14 on the side wall of the wire wheel 12. The pulling rope 14 pulls the detection wire 16 to be wound on the side wall of the wire wheel 12 synchronously, storing the detection wire 16. There is no need for the user to rotate the wire wheel 12, improving the convenience of using this device;

[0024] By pulling one end of the detection wire, pulling the detection wire out of the circular groove, the detection wire drives the wire wheel to rotate, and the other end of the detection wire takes the square block out of the inclined groove. The limiting component limits the square block, facilitating the storage of the detection wire, preventing the loss of the detection wire, and ensuring the normal use of the detector.

[0025] The limiting component includes square grooves 20 formed in the upper and lower side walls of the inclined groove 18. Limiting blocks 21 are slidably assembled in both square grooves 20. Semi-circular holes matching the detection line 16 are formed in both limiting blocks 21. Springs 21 are provided between both limiting blocks 21 and the side walls of the square grooves 20. Square openings communicating with the square grooves 20 are formed in the side wall of the tester body 1. Pressing blocks 22 matching the square openings are fixedly provided on the side walls of both limiting blocks 21;

[0026] When the utility model is not in use, under the elastic action of the spring 21, both limiting blocks 21 extend out of the square groove 20, and both limiting blocks 21 clamp the detection line 16;

[0027] During the use of the utility model, when taking out the detection line 16, after the user pulls the detection line 16 out to a certain length, then pushes both pressing blocks 22 in the up and down directions. Both pressing blocks 22 synchronously drive both limiting blocks 21 to move, compressing the springs 21 on the upper and lower sides. The user then pulls the detection line 16 to pull the square block 15 out of the inclined groove 18. When the user releases the pressing of both pressing blocks 22, under the elastic action of the spring 21, both limiting blocks 21 slide towards the middle of the inclined groove 18. After taking out the plug end of the detection line 16 from the jack 17 of the square block 15, under the winding action of the torsion spring 13, the wire wheel 12 is driven to rotate, winding the pull rope 14 on the side wall of the wire wheel 12, pulling the square block 15 to slide towards the circular groove 10, making the side wall of the square block 15 abut against the side wall of the limiting block 21, and the limiting block 21 limits the square block 15, facilitating the user to operate the square block 15 and ensuring the smooth use of the device.

[0028] One side of both limiting blocks 21 close to the wire wheel 12 is processed into an inclined surface; when taking out the detection line 16, without the user pushing the pressing block 22, during the movement of the square block 15, the inclined surface of the limiting block 21 pushes the limiting block 21 to move, so that the square block 15 slides out of the inclined groove 18, improving the use convenience of the device.

[0029] A transparent protective cover 30 is rotatably assembled on the front side of the tester body 1; when the utility model is stored, it protects the front ends of the tester body 1 and the detection line 16 from being damaged.

[0030] Two linearly distributed handles 31 are fixedly provided on the upper side of the tester body 1; facilitating the user to move the tester body 1.

[0031] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
