[0041] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0042] according to Figure 1-2 As shown, this utility model embodiment provides a quick-release mechanism for an instrument data acquisition terminal 1, including: quick-release component 2, quick-release component 3 detachably connected to one side, and data acquisition terminal 1 installed on the other side. The end of quick-release component 3 away from quick-release component 2 is used to install the data acquisition terminal 1 at a preset construction position.

[0043] In this utility model, the data acquisition terminal 1 and the quick-release component 2 are fixedly connected as one unit. The data acquisition terminal 1 integrates an acquisition system for collecting instrument data. This system is existing technology. The improvement of this utility model is that when the installation environment is not suitable for the guide rail installation method, the instrument monitoring device (data acquisition terminal 1) can be installed through the solution provided by this utility model. The quick-release structure can realize the purpose of quick assembly of quick-release components of different specifications, so that the instrument data acquisition terminal can not only overcome the problem of installation without guide rail, but also achieve the purpose of adapting quick-release components of different sizes according to different installation environments.

[0044] In one embodiment, according to Figures 1-3 As shown, quick-release component 2.3 has a U-shaped structure.

[0045] The U-shaped opening end of quick-release part 2 3 and quick-release screw 4 form an installation and locking space, which is used to install the data acquisition terminal 1 in a preset construction position; one end of quick-release screw 4 is a butterfly handle, and the other end of quick-release screw 4 is threadedly connected to quick-release nut 5.

[0046] In this embodiment, the U-shaped structure of the quick-release component 3 facilitates the installation of the data acquisition terminal 1 on pipes, poles, and plates on site. Furthermore, during use, the quick-release nut 5 can be welded and fixed to the side wall of the U-shaped structure. By operating the butterfly handle of the quick-release screw 4, the screw and the quick-release screw 4 are loosened, making it easy to snap the U-shaped structure into the required installation position. After it is snapped in place, the threaded end of the quick-release screw 4 and the quick-release nut 5 are engaged to perform threaded assembly, thereby closing the installation space and quickly completing the assembly and fixation of the data acquisition terminal 1.

[0047] In one embodiment, according to Figures 1-3 As shown, quick-release component 1 (2) and quick-release component 2 (3) are detachably connected via quick-release assembly.

[0048] The quick-release components include:

[0049] The snap-fit ​​assembly is located in the snap-fit ​​section 32 of quick-release component 2;

[0050] The button assembly, located on quick-release component 2, cooperates with the snap-on assembly and is used to lock or release quick-release component 2 and quick-release component 3.

[0051] In this embodiment, the scheme for replacing U-shaped structures of different specifications is further refined. That is, when the size of the U-shaped structure does not match during the actual operation of the construction section (installation position), the construction personnel can quickly replace the quick-release part 2 3 to realize the size of the installation space of the U-shaped structure can be adjusted, so as to achieve the purpose of diversifying the installation method of the data acquisition terminal 1 and making it more adaptable.

[0052] In one embodiment, according to Figure 2-3 As shown,

[0053] The quick-release component 2 includes: a housing 21, one side of which is fixedly connected to the back of the data acquisition terminal 1, and the other side is provided with a quick-release slot 22; the side wall of the quick-release slot 22 is provided with a button assembly, which cooperates with the quick-release component 3 to achieve a detachable connection.

[0054] Quick-release component 2 includes: a quick-release link, one end of which is a link segment 31, which is connected to a U-shaped clip; the concave surface of the U-shaped clip is provided with a rubber layer, and the surface of the rubber layer is an anti-slip mesh; the other end of the quick-release link is a locking segment 32, and the side wall of the locking segment 32 is provided with a buckle assembly.

[0055] In this embodiment, the U-shaped structure is further refined into a U-shaped clip. The side of the U-shaped clip away from the U-shaped opening is a rod-shaped quick-release link. The quick-release link includes a link section 31 and a locking section 32. The link section 31 is connected to the U-shaped clip, and the locking section 32 is detachably connected to the housing 21.

[0056] In one embodiment, according to Figure 2-3 As shown, the snap-fit ​​assembly is movably disposed in the second movable groove 33 on the side wall of the connecting rod section 31. The snap-fit ​​assembly includes: a limiting rod 34, one end of which is provided with a spherical limiting block 36, and the other end is provided with a spring groove 37, in which a second spring 35 is installed; the other end of the second spring 35 is connected to the bottom of the second movable groove 33.

[0057] The side wall of the housing 21 is provided with a movable groove 26, in which a button assembly is slidably disposed; the axes of the movable groove 33 and the movable groove 26 are coaxially arranged, which allows the button assembly and the snap-fit ​​assembly to correspond and reciprocate on the same axis.

[0058] The button assembly includes: a push rod 27, and at least two sets of outwardly protruding sliders 25 on the side wall; one end of the push rod 27 is a raised spherical structure, and the other end is a concave hemispherical arc groove 38; the inner wall of the movable groove 26 is provided with a guide groove 23, and the guide groove 23 and the slider 25 correspond to each other and slide in fit; a second spring 35 is sleeved on one end of the push rod 27 near the arc groove 38, one end of the second spring 35 abuts against the side wall of the guide groove 23, and the other end abuts against the side wall of the slider 25.

[0059] The first spring 24 and the second spring 35 are normally in the extended state; after the first spring 24 is compressed, the arc-shaped groove 38 of the push rod 27 abuts against the limiting block 36, causing the limiting rod 34 to retract into the movable groove 33.

[0060] Both the quick-release slot 22 and the spring slot 37 have a blade retraction groove 28 at their bottom.

[0061] In this embodiment, by further refining the specific quick-release structure of the buckle assembly, the U-shaped clip can be changed according to different installation requirements during actual use.

[0062] Specifically, the usage steps are as follows:

[0063] When it is necessary to install the data acquisition terminal 1, use the butterfly handle on the quick-release screw 4 to disassemble the quick-release nut 5 and one end of the quick-release screw 4, that is: open the installation space; after inserting the opening of the U-shaped structure into the installation position, use the butterfly handle to install the quick-release screw 4 and the quick-release nut 5, and the installation of the data acquisition terminal 1 can be completed.

[0064] In practical use, the data acquisition terminal 1 can be used for meter reading or, depending on project needs, as an instrument monitoring terminal to monitor the instrument's usage and fault status. Solutions for different monitoring purposes are not the focus of this utility model's protection; they are merely extensions of its intended use. In other words, the technical solution proposed in this utility model can achieve different monitoring functions by replacing the internal monitoring / control system or modules without changing the external structure. In practical use, the data acquisition terminal 1 internally includes a monitoring module, a power module, an internet module (data transmission module, which can be wired or wireless), and a power supply module, constituting the necessary hardware modules for achieving different monitoring purposes.

[0065] Under normal conditions, the limiting rod 34 is inserted into the movable slot 26 to achieve the purpose of limiting and locking; when it is necessary to replace the quick-release part 3 during use, press the top rod 27, and the sliders 25 on both sides of the top rod 27 move along the guide groove 23. Figures 2-3 In the schematic diagram shown, the push rod moves to the left, causing the first spring 24 to compress. When the left side of the push rod 27 pushes out of the movable groove 26, the arc-shaped groove 38 at the end of the push rod 27 abuts against the spherical outer wall of the left limiting block 36, pushing it to move to the left along with the limiting rod 34. The second spring 35 is further compressed, and at this time the limiting rod 34 disengages from the movable groove 26. The U-shaped clip can be lifted to complete the disassembly.

[0066] After disassembly, select the appropriate U-shaped clip and insert the locking section 32 of the quick-release linkage of the appropriate U-shaped clip into the quick-release slot 22. Since the limiting block 36 is spherical, the spherical structure will have a certain guiding purpose when entering the quick-release slot 22, so that the limiting block 36 can slide smoothly into the quick-release slot 22. When the limiting block 36 reaches the position of the movable slot 26, the second spring 35 of the limiting block 36 returns to its normal state and pushes the limiting block 36 to the right, so that it can be locked into the movable slot 26, completing the quick replacement of the U-shaped clip.

[0067] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
