[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-4 and attached Figure 6-7 A low-voltage cabinet temperature measuring device that is easy to install is shown, comprising a temperature measuring device body 1, a flexible gasket 2 is provided at one end of the outer wall of the temperature measuring device body 1, a magnetic sheet 3 is provided inside the flexible gasket 2, a plurality of flexible gasket strips 4 are provided on the outer wall of the flexible gasket 2 on the outer side of the temperature measuring device body 1, a limiting groove 5 matching the flexible gasket strip 4 is provided on the outer wall of the temperature measuring device body 1, a plurality of connecting frames 6 are provided on the outer wall of the magnetic sheet 3 close to the temperature measuring device body 1, the connecting frame 6 passes through and extends to the outside of the temperature measuring device body 1, a first cavity 7, a second cavity 8 and a third cavity 9 are provided inside the flexible gasket 2, and the second cavity 8 is provided between the first cavity 7 and the third cavity 9. The first cavity 7 is arranged inside the flexible gasket 2 close to the side of the temperature measuring device body 1, the magnetic sheet 3 is arranged inside the first cavity 7, a first flexible isolation sheet 10 is arranged between the first cavity 7 and the second cavity 8, a second flexible isolation sheet 11 is arranged between the second cavity 8 and the third cavity 9, a plurality of air holes 12 are opened on the surface of the second flexible isolation sheet 11, a fourth cavity 13 is arranged inside the flexible pad 4, the fourth cavity 13 is connected with the outer wall of the third cavity 9, a third flexible isolation sheet 14 is arranged on the outer wall of the magnetic sheet 3, and the third flexible isolation sheet 14 is fixedly connected to the outer wall of the first flexible isolation sheet 10.

[0029] The sum of the thicknesses of the outer walls of the first flexible isolation sheet 10, the second flexible isolation sheet 11 and the flexible gasket 2 on the side away from the temperature measuring device body 1 is less than the thickness of the magnetic sheet 3, ensuring that the magnetic sheet 3 can be magnetically adsorbed and connected to the low-voltage cabinet through the first flexible isolation sheet 10, the second flexible isolation sheet 11 and the flexible gasket 2, thereby avoiding the partition being too thick to affect the fixed connection effect.

[0030] The outer wall of the flexible gasket 2 is provided with a through hole 16 matching the connecting frame 6 , and the through hole 16 is for the connecting frame 6 to pass through, so as to ensure that the connecting frame 6 can pass through the flexible gasket 2 to adjust the magnetic sheet 3 .

[0031] An installation groove 15 matching the flexible gasket 2 is provided at one end of the outer wall of the temperature measuring device body 1, and a display 22 is provided at one end of the outer wall of the temperature measuring device body 1 away from the installation groove 15. The flexible gasket 2 is installed on the inner side of the installation groove 15 of the temperature measuring device body 1, and the display 22 is used to display temperature measurement data.

[0032] The flexible gasket 2 is fixedly connected to the mounting groove 15 to ensure the stability of the flexible gasket 2. One side of the outer wall of the flexible gasket strip 4 is fixedly connected to the limiting groove 5 to ensure the stability of the flexible gasket strip 4 and prevent the flexible gasket 2 and the flexible gasket strip 4 from being separated from the temperature measuring device body 1.

[0033] The volumes of the second cavity 8 and the third cavity 9 are smaller than the maximum volume of the fourth cavity 13, ensuring that all the air inside the second cavity 8 and the third cavity 9 can be squeezed into the fourth cavity 13, and the fourth cavity 13 will not be broken.

[0034] The specific implementation method is as follows: when in use, by setting the flexible gasket 2, the magnetic sheet 3, the flexible pad strip 4, the limiting groove 5, the connecting frame 6, the first cavity 7, the second cavity 8, the third cavity 9 and the fourth cavity 13, the connecting frame 6 is pulled outward, the magnetic sheet 3 moves in the first cavity 7 toward the direction close to the temperature measuring device body 1, the internal space of the second cavity 8 and the third cavity 9 is restored to the un-squeezed state, the air storage capacity in the fourth cavity 13 becomes less, the flexible pad strip 4 is located on the inner side of the limiting groove 5 and will not extend out of the limiting groove 5. At this time, the temperature measuring device body 1 is aligned with the embedding groove on the low-voltage cabinet, the temperature measuring device body 1 is directly pushed inward, and the temperature measuring device body 1 is inserted into the embedding groove. When the temperature measuring device body 1 is fully inserted into the embedding groove, the magnetic sheet 3 is aligned with the embedding groove. The inner wall is subjected to magnetic adsorption treatment to realize magnetic adsorption treatment on the end of the temperature measuring device body 1, and the magnetic sheet 3 moves the first flexible isolation sheet 10, the second flexible isolation sheet 11 and the third flexible isolation sheet 14 in the direction away from the temperature measuring device body 1, and the magnetic sheet 3 cooperates with the first flexible isolation sheet 10 to squeeze the second cavity 8, and the air inside the second cavity 8 passes through the air vent 12 of the second flexible isolation sheet 11 into the third cavity 9, and the magnetic sheet 3 cooperates with the second flexible isolation sheet 11 to squeeze the air inside the third cavity 9 into the fourth cavity 13, and the air storage inside the fourth cavity 13 increases, and the fourth cavity 13 expands, so that the flexible pad strip 4 collides and becomes larger, and the flexible pad strip 4 extends to the outside of the limit groove 5, and the flexible pad strip 4 extends to the outside of the limit groove 5. The outer wall of the flexible pad strip 4 is in close contact with the inner wall of the embedded groove, so that the side wall of the temperature measuring device body 1 is clamped and fixed. At the same time, the flexible gasket 2 and the flexible pad strip 4 can perform flexible buffering on the outside of the temperature measuring device body 1, which has a better protection effect on the temperature measuring device body 1. When the distance between the magnetic sheet 3 and the inner wall of the embedded groove is large and the magnetic attraction is insufficient, the connecting frame 6 can be pushed inward, and the connecting frame 6 pushes the magnetic sheet 3 to move away from the temperature measuring device body 1. The distance between the magnetic sheet 3 and the inner wall of the embedded groove becomes smaller, and the magnetic attraction becomes larger, thereby ensuring the installation and fixing effect of the temperature measuring device body 1. When the temperature measuring device body 1 is disassembled, the connecting frame 6 is directly pulled outward to move the magnetic sheet 3 toward the side close to the temperature measuring device body 1. The magnetic attraction gradually decreases, and the first flexible insulation The extrusion pressure of the separation sheet 10 and the second flexible isolation sheet 11 gradually decreases, the first flexible isolation sheet 10 and the second flexible isolation sheet 11 rebound, the internal space of the third cavity 9 and the second cavity 8 becomes larger, the air inside the fourth cavity 13 moves into the second cavity 8 and the third cavity 9, the air storage of the fourth cavity 13 becomes smaller, and the fourth cavity 13 retracts, so that the flexible pad 4 retracts into the inside of the limiting groove 5 and no longer contacts the inner wall of the embedded groove. At the same time, the third flexible isolation sheet 14 moves with the magnetic sheet 3, and the first flexible isolation sheet 10 can be pulled to ensure that the internal space of the second cavity 8 and the second cavity 9 rebounds quickly, and then the connecting frame 6 is continued to be pulled outward, and the temperature measuring device body 1 can be disassembled, which is convenient and quick to operate;This embodiment specifically solves the problem that the existing low-voltage cabinet temperature measuring devices in the background technology mostly adopt embedded installation design, but the operation is cumbersome and the installation convenience is poor. ;

[0035] As attached Figure 1-7 A low-voltage cabinet temperature measuring device that is easy to install is shown, wherein the connecting frame 6 includes a support rod 17, one end of the support rod 17 is fixedly connected to the magnetic sheet 3, and the other end of the support rod 17 is provided with a first connecting ball 18 on the outside of the temperature measuring device body 1, and a second connecting ball 19 is provided on the outer wall of the first connecting ball 18 away from the end of the support rod 17, and a through groove 20 matching the support rod 17 is provided inside the temperature measuring device body 1, and a spherical groove 21 matching the first connecting ball 18 is provided on the outer wall of the temperature measuring device body 1, and the spherical groove 21 is connected to the through groove 20.

[0036] The outer diameter of the support rod 17 is half of the outer diameter of the first connecting ball 18, ensuring that the first connecting head 18 cooperates with the spherical groove 21 to limit the support rod 17, and the limiting effect is good. The outer diameter of the first connecting ball 18 is half of the outer diameter of the second connecting ball 19, ensuring that the second connecting ball 19 and the first connecting ball 18 adopt a gradient size design, which is more convenient and quick when held in hand.

[0037] The support rod 17 is made of insulating material to ensure that the support rod 17 will not have adverse effects on the temperature measuring device body 1. The first connecting ball 18 and the second connecting ball 19 are made of flexible insulating material, which makes the first connecting ball 18 and the second connecting ball 19 more convenient and quick to use, and can perform flexible buffering treatment on the temperature measuring device body 1.

[0038] The specific implementation method is as follows: when in use, by setting the support rod 17, the first connecting ball 18, the second connecting ball 19, the through groove 20 and the spherical groove 21, the support rod 17 can be pushed inward by holding the second connecting ball 19, and the support rod 17 slides along the through groove 20, the support rod 17 pushes the magnetic sheet 3, and the through groove 20 guides the support rod 17 to ensure the stability of the support rod 17, and the first connecting ball 18 is inserted into the spherical groove 21 to limit the position of the support rod 17, thereby limiting the position of the magnetic sheet 3 to ensure the stability of the magnetic sheet 3. At the same time, under the magnetic attraction of the magnetic sheet 3, the first connecting ball 18 can be tightly inserted into the inner side of the spherical groove 21, and the spherical groove 21 and the through groove 20 are sealed to prevent dust from entering the gap between the connecting frame 6 and the temperature measuring device body 1, thereby ensuring the safety of the flexible gasket 2. At the same time, the first connecting ball 18 and the second connecting ball 19 cooperate to achieve anti-collision treatment of the outside of the temperature measuring device body 1, and the temperature measuring device body 1 has high safety performance.

When the connecting frame 6 is pulled outward, the air storage volume of the fourth cavity 13 becomes smaller, and the fourth cavity 13 is retracted, so that the flexible pad 4 is retracted into the limiting groove 5 and no longer contacts the inner wall of the embedded groove.
