[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] Please see Figure 1-7 The present invention provides the following technical solution:

[0040] A protective sleeve structure for a pH meter used in electrophoresis experiments, comprising:

[0041] pH meter body 1;

[0042] The protective sleeve body 5 is located on one side of the pH meter body 1;

[0043] Wire 2 is fixedly connected to the upper end of pH meter body 1, and sealing cap 6 is fixedly connected to the lower end of wire 2. Measuring electrode 8 is fixedly connected to the lower end of sealing cap 6.

[0044] Multiple protective mechanisms, each including:

[0045] The sliding groove 10 is formed on the inner surface of the protective sleeve body 5. The inner surface of the sliding groove 10 is slidably connected to the limiting plate 11. One end of the limiting plate 11 is fixedly connected to the sliding block 12. One end of the sliding block 12 is fixedly connected to the clamping plate 13. The outer surface of the clamping plate 13 is fixedly connected to the clamping pad 14.

[0046] A limiting component is disposed within the sliding groove 10 to limit the sliding of the sliding block 12; and

[0047] An elastic component is provided within the sliding groove 10 to support the limiting component.

[0048] In a specific embodiment of this utility model, the pH meter body 1 is the core measuring device body, used to process electrode signals and display pH values. The protective sleeve body 5 is a rigid protective shell fitted over the outside of the pH meter body 1, isolating it from strong electric fields, solution splashes, and physical collisions during electrophoresis experiments. The wire 2 transmits the electrical signal from the measuring electrode 8 to the pH meter body 1 and must be corrosion-resistant. The sealing cap 6 connects the wire 2 to the measuring electrode 8, ensuring a seal at the electrode interface to prevent liquid ingress. The measuring electrode 8 directly contacts the solution to be tested to acquire the pH signal. The sliding groove 10 is a longitudinal slide rail formed on the inner wall of the protective sleeve body 5, providing a sliding path for the clamping mechanism. The limiting plate 1... The plate-like structure embedded in the sliding groove 10 converts the lateral movement of the sliding block 12 into longitudinal sliding. The sliding block 12 connects the limiting plate 11 and the clamping plate 13, transmitting the sliding action. The clamping plate 13 directly contacts the rigid plate of the electrode, fixing the electrode position through clamping force. The clamping pad 14 conforms to the flexible material of the clamping plate 13, increasing friction and preventing scratches on the electrode. The limiting groove 15 is formed in the grooves on both sides of the inner wall of the sliding groove 10, guiding the limiting block 16 to slide in a specific direction. The block-like structure of the limiting block 16 is embedded in the limiting groove 15, mechanically linking the sliding block 12 and the limiting groove 15 to ensure that the sliding direction is perpendicular. The baffle 17 is fixed to the enlarged end of the limiting block 16. To prevent the limiting block 16 from dislodging from the limiting groove 15, the mounting base 18 is fixed to the base of the inner wall of the limiting groove 15 and is used to fix one end of the spring 19. The spring 19 is sleeved on the compression spring 19 of the mounting base 18, which pushes the limiting block 16 back to the initial position and provides adaptive clamping force. The control groove 20 is opened in the through groove at the bottom of the protective sleeve body 5, allowing external operating parts to enter. The connecting block 21 passes through the connector of the control groove 20, with the upper end fixed to the sliding block 12 and the lower end fixed to the control block 22. The control block 22 is exposed on the operating button of the protective sleeve body 5, and the clamping mechanism is opened and closed by manual pressing. The parallel groove 23 is opened in the protective sleeve body 5. The symmetrical sliding groove at the bottom is parallel to the control groove 20. The parallel block 24 is embedded in the slider of the parallel groove 23, and the control block 22 is fixed at the upper end, thereby restricting the control block 22 to move only vertically. This strengthens the protection of the pH meter for the measuring electrode 8, solves the problem of collision between the measuring electrode 8 and the pH meter during carrying, avoids the probability of damage to the measuring electrode 8, improves the working efficiency of the pH meter, and reduces the waste of time and resources. It should be noted that the specific model of pH meter body 1 used shall be selected by those skilled in the art, and the above-mentioned pH meter body 1, etc., are all existing technologies, which will not be elaborated in this solution.

A baffle 17 is fixedly connected to one end of each of the two limiting blocks 16.

[0057] The parallel component is set inside the protective sleeve body 5 to limit the parallel sliding of the sliding control block 22.

[0058] In this embodiment: the control groove 20 is opened in the through groove at the bottom of the protective sleeve body 5, allowing external operating components to enter. The connecting block 21 passes through the connector of the control groove 20, with the upper end fixed to the sliding block 12 and the lower end fixed to the control block 22. The control block 22 is exposed to the operating button of the protective sleeve body 5, and the clamping mechanism is opened and closed by manual pressing. The parallel groove 23 is opened in the symmetrical sliding groove at the bottom of the protective sleeve body 5, parallel to the control groove 20. The parallel block 24 is embedded in the slider of the parallel groove 23, and the upper end is fixed to the control block 22, thereby restricting the control block 22 to only move vertically.

[0059] Please refer to the details. Figure 6 Each set of parallel components includes:

[0060] Two parallel grooves 23 are provided at the lower end of the protective sleeve body 5. Parallel blocks 24 are slidably connected to the inner surfaces of the two parallel grooves 23.

[0064] Please refer to the details. Figure 7 The outer surface of the conductor 2 is provided with a first support seat 3 and a second support seat 4.

[0065] In this embodiment, the first support 3 and the second support 4 are provided to realize the snap-fit ​​structure for clamping the wire 2, thereby dispersing the stress on the wire 2 and preventing the interface from becoming loose or broken.

[0066] The working principle and usage process of this utility model are as follows: First, insert the measuring electrode 8 into the protective sleeve body 5, so that it passes through the rubber tube sleeve 7 and abuts against the protective pad 9. Then, release the control block 22. At this time, the spring 19 pushes the limit block 16 to reset, causing the sliding block 12 to move inward, thereby causing the two clamping plates 13 to close inward. The two clamping pads 14 are tightly attached to the electrode surface to achieve self-adaptive fixation. Insert the wire 2 into the first support seat 3 and the second support seat 4 to disperse the mechanical stress of the interface. Align the sealing cover 6 with the upper end of the protective sleeve body 5.
