[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0021] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0022] Please refer to Figure 1 ,Figure 2 、 Figure 3 A quick plug-in connection structure of a collection module, which is consistent with the prior art device, the device comprising a signal collection module 2 and a measurement module 1.

[0023] On one side of the signal collection module 2, two low bosses 3 structures are specially designed, and a high boss 4 structure is arranged on the same side of the two low bosses 3. In addition, the two low bosses 3 are distributed in a left-right symmetrical manner.

[0024] Please refer to Figure 2 、 Figure 3 Compared with the prior art device, the two low bosses 3 are characterized in that they are designed as a hollow structure inside, and the proximal end is open, thereby forming an open structure.

[0025] Therefore, in the interior of each low boss 3, a positioning rod 10 extending along the left-right axis is fixedly connected. At the same time, a limiting block 8 is arranged at the proximal end of the two positioning rods 10. Each limiting block 8 is provided with a positioning groove for the positioning rod 10 on the side adjacent to the adjacent positioning rod 10, and the positioning rod 10 can be inserted into the positioning groove. Through this matching mode, the positioning rod 10 and the positioning groove jointly limit the movement track of the limiting block 8, ensuring that the two limiting blocks 8 can only move towards or away from each other.

[0026] In addition, a compression spring 9 is additionally arranged outside the positioning rod 10, and the two axial ends of the spring are tightly attached to the inner wall of the low boss 3 and the limiting block 8, respectively, thereby giving the two limiting blocks 8 a tendency to move towards each other.

[0027] Please refer to Figure 4 、 Figure 5 At the same time, the device is provided with a cooperation rod 5 with a vertical plane in an L-shaped structure inside the measurement module 1 for the two low bosses 3. By constraining the left-right symmetrical arrangement of the two cooperation rods 5, it is ensured that the horizontal sections of the two cooperation rods 5 are located at the distal ends. At this time, when the horizontal section of the cooperation rod 5 is located below the limiting block 8, the distance between the measurement module 1 and the signal collection module 2 is limited by the interaction between the limiting block 8 and the cooperation rod 5, thereby ensuring the stable connection of the two.

[0028] Further, in order to realize the quick connection between the measuring module 1 and the signal acquisition module 2, the device is designed with the lower end of the two matching rods 5 as an inclined surface, i.e. the lower end of each matching rod 5 is smaller in width than the upper end. This design makes the inclined surface of the matching rod 5 force the two limiting blocks 8 to move away from each other when the matching rod 5 moves downward and hits the limiting blocks 8. In this state, when the horizontal section of the matching rod 5 is at the same level as the limiting blocks 8, the compression spring 9 is in a compressed state, and the limiting blocks 8 are embedded in the short boss 3.

[0029] It should be pointed out that when the horizontal section of the matching rod 5 moves to the lower side of the limiting block 8, a stable connection is established between the measuring module 1 and the signal acquisition module 2. At this time, the elastic potential energy stored in the compression spring 9 is released, causing the limiting block 8 to protrude from the short boss 3 and come into close contact with the vertical section of the limiting block 8.

[0030] Further, in order to realize the quick connection between the measuring module 1 and the signal acquisition module 2, the device is designed with the lower end of the two matching rods 5 as an inclined surface, i.e. the lower end of each matching rod 5 is smaller in width than the upper end. This design makes the inclined surface of the matching rod 5 force the two limiting blocks 8 to move away from each other when the matching rod 5 moves downward and hits the limiting blocks 8. In this state, when the horizontal section of the matching rod 5 is at the same level as the limiting blocks 8, the compression spring 9 is in a compressed state, and the limiting blocks 8 are embedded in the short boss 3.

[0031] It should be pointed out that when the horizontal section of the matching rod 5 moves to the lower side of the limiting block 8, a stable connection is established between the measuring module 1 and the signal acquisition module 2. At this time, the elastic potential energy stored in the compression spring 9 is released, causing the limiting block 8 to protrude from the short boss 3 and come into close contact with the vertical section of the limiting block 8.

[0032] Specifically, the device is designed with a sliding groove on the vertical section of each matching rod 5, and the limiting block 6 is embedded in the sliding groove to realize the sliding connection with the matching rod 5.

[0033] Further, to ensure that the limiting block 8 can be actively inserted between the horizontal portion of the fitting rod 5 and the releasing limiting piece 6, so as to ensure that the limiting block 8 can be actively embedded between the fitting rod 5 and the releasing limiting piece 6 when the horizontal portion of the fitting rod 5 moves to below the limiting block 8, thereby limiting the fitting rod 5. The device is fixedly installed with an elastic element 12 in each sliding groove. Under this structure, when the elastic element 12 is not subjected to external force and the releasing limiting piece 6 is in contact with the elastic element 12, the height of the lower end surface of the releasing limiting piece 6 is greater than the height of the fitting rod 5. Therefore, in the case that there is a gap between the limiting block 8, the releasing limiting piece 6 and the horizontal portion of the fitting rod 5, the inclined surface of the limiting block 8 itself will exert an upward thrust on the releasing limiting piece 6. At this time, the elastic potential energy stored by the compression spring 9 can be used to ensure that the limiting block 8 can be actively inserted between the horizontal portion of the fitting rod 5 and the releasing limiting piece 6.

[0034] Further, the device uses rubber material for the constraint elastic element. Meanwhile, in the case that the elastic element is not subjected to external force and the releasing limiting piece 6 is in contact with the elastic element, the distance between the lower end surface of the releasing limiting piece 6 and the upper end surface of the horizontal segment of the fitting rod 5 is designed to be less than the height of the limiting block 8. The main purpose of this design is to ensure that the manufacturing cost of the elastic element is kept within a reasonable range, and to prevent irreversible deformation of the elastic element, thereby avoiding premature damage to the device.

[0035] Specifically, the device adjusts the position of the limiting block 8 by sliding the releasing limiting piece 6 downward, thereby releasing the limiting effect of the limiting block 8 on the fitting rod 5. Therefore, to ensure that the releasing limiting piece 6 can move downward, the device is configured with a sliding rail 11 on the left and right sides of the measuring module 1, each sliding rail 11 corresponding to a releasing limiting piece 6. A sliding rod 7 is embedded in the sliding rail 11, which can move linearly in the left and right directions relative to the measuring module 1 in the sliding rail 11. By designing the distal end of the releasing limiting piece 6 as an inclined surface, and the width of the upper end of each releasing limiting piece 6 being less than the width of the lower end, when the sliding rod 7 is in contact with the fitting rod 5, the lower end surface of the releasing limiting piece 6 is in contact with the upper end surface of the horizontal segment of the fitting rod 5, thereby realizing the up and down movement of the releasing limiting piece 6 by the left and right movement of the sliding rod 7.

[0036] Therefore, the distal ends of the two sliding rails 11 are in an open structure, and the distal ends of the two sliding rods 7 protrude into the sliding rails 11, so as to ensure the controllability of the sliding rods 7 by the user.

[0037] It should be particularly pointed out that the device realizes the vertical movement of the releasing limiting piece 6 by the left and right movement of the sliding rod 7, which is consistent with the position of the fingers of the user when plugging and unplugging the measuring module 1 in actual operation. Therefore, the user does not need to perform additional operations, and can effectively control the positions of the two sliding rods 7 by normally holding the measuring module 1.

[0038] It must be pointed out that in practical application, the width of the slide rail 11 should be substantially the same as the width of the low boss 3, and the design makes the high boss 4 be able to be embedded in the gap formed by the slide rail 11 and the inner wall of the measuring module 1 when the signal acquisition module 2 is in contact with the measuring module 1, thereby further guaranteeing the stability and reliability of the device.

[0039] In the practical application of the utility model, when the measuring module 1 needs to be connected with the data acquisition module:

[0040] Firstly, the measuring module 1 should be aligned with the data acquisition module, and pressure should be applied to the measuring module 1, at this time, the lower end surface of the horizontal section of the matching rod 5 is in contact with the limiting block 8.

[0041] Then, with the downward movement of the matching rod 5, the two limiting blocks 8 move in opposite directions, and the two compression springs 9 are continuously compressed until the matching rod 5 is completely moved below the limiting block 8.

[0042] Finally, the limiting block 8 is embedded between the horizontal section of the matching rod 5 and the releasing limiting piece 6, the elastic potential energy stored by the compression spring 9 is released, and the releasing limiting piece 6 moves upward and separates from the elastic piece 12.

[0043] In the practical application of the utility model, when the measuring module 1 needs to be separated from the data acquisition module:

[0044] Firstly, the user presses the slide rod 7 so that the palm position corresponds to the upper end surface of the measuring module 1.

[0045] Then, with the continuous movement of the two slide rods 7, the two releasing limiting pieces 6 move downward at the same time, and the limiting block 8 moves in the opposite direction, and the two compression springs 9 are continuously compressed.

[0046] Then, with the further downward movement of the slide rod 7, the two releasing limiting pieces 6 come into contact with the corresponding elastic pieces 12, and the elastic pieces 12 are continuously compressed, and the user needs to continuously press the slide rod 7 until the two slide rods 7 cannot continue to move towards each other.

[0047] Finally, the user pulls the measuring module 1 upward to complete the separation process.

[0048] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
