[0036] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0037] refer to Figures 1 to 8In the first aspect, the present application provides an anti-theft sealing assembly, comprising: a screw 4, the outer wall surface of which has a nut with a circumferential annular groove; a sealing sleeve, on which a hook 11 is provided to be engaged in the annular groove of the screw 4, and the sealing sleeve and the screw 4 are detachable.

[0038] In a second aspect, the present application provides an electric energy meter equipped with the anti-theft seal assembly. In the present application, the anti-theft seal assembly is assembled on the electric energy meter as a specific embodiment, but it is not limited thereto.

[0039] In this embodiment, the anti-theft sealing component seals the screw 4 through a sealing sleeve to prevent the screw 4 from being screwed privately, thereby playing a sealing role.

[0040] In this embodiment, reference Figures 1 to 8 The sealing sleeve comprises: a sleeve 5, one end of which is provided with a limiting shoulder toward its axis, and the screw 4 coaxially penetrates into the sleeve 5 and is limited by the limiting shoulder. Figure 2 , after the screw 4 passes through the pipe sleeve 5, it is installed in the installation hole of the electric energy meter together with the pipe sleeve 5; the sealing cap 1 is a tubular structure with one end closed, and the sealing cap 1 is provided with at least one slide groove extending along its axial direction; the tubular clamping part 3, the outer wall of which is provided with a positioning block 9 adapted to the slide groove, the clamping part 3 is provided with at least three limit pieces 10 near its first end, and the clamping part 3 is provided with at least three hooks 11 near its second end, each The limiting plate 10 and each of the hooks 11 are evenly distributed along the circumference of the clamping member 3, and each of the limiting plate 10 and each of the hooks 11 deviates toward the axis of the clamping member 3; the lining member 2 is coaxially arranged in the clamping member 3 along the first end of the clamping member 3; wherein the clamping member 3 is slidably clamped in the sealing cap 1, the sealing cap 1 is coaxially arranged in the pipe sleeve 5, and each of the hooks 11 of the clamping member 3 is clamped on the screw 4.

[0041] In this embodiment, the sealing cap 1 is evenly provided with three sliding grooves in the circumferential direction, and the clamping part 3 is adapted to be provided with three positioning blocks 9, so as to realize the axial sliding of the clamping part 3 into the sealing cap 1, and the three positioning blocks 9 are adapted to slide into each of the sliding grooves, so as to limit the circumferential sliding of the clamping part 3 in the sealing cap 1.

[0042] In this embodiment, the clamping member 3 is made of stainless steel or other materials with good elasticity, which increases the fatigue limit of deformation and ensures that it has good elasticity, making it convenient to seal and unseal.

[0043] In this embodiment, the lining member 2 is first installed in the clamping member 3, and the two are transitionally matched. As a person skilled in the art should understand, the lining member 2 is coaxially installed from the first end of the clamping member 3, and the limiting piece 10 opened in the clamping member 3 can block the lining member 2 from continuing to enter. Figure 6 and Figure 7 Then install the clamping member 3 with the limit plate 10 installed into the sealing cap 1, refer to Figure 8 Finally, the assembly of the above three parts is pressed into the sleeve 5, so that the hook 11 on the clamping part 3 touches the nut of the screw 4, and then the sleeve 5 is pressed further, the nut pushes the three hooks open, and the bent parts of the tips of the three hooks are stuck in the annular groove of the nut, so that the sleeve 5 is stuck on the screw 4, and the screw 4 is sealed.

[0044] In this embodiment, there is a clearance fit between the sealing cap 1 and the tube sleeve 5 , which makes it very easy to press the sealing cap 1 into the tube sleeve 5 , and also convenient to unseal the seal and take the sealing cap 1 out of the tube sleeve 5 .

[0045] In this embodiment, the closed end of the sealing sleeve adopts a plastic film structure to facilitate unsealing. The diameter of the closed end is smaller than the diameter of the inner sleeve, so that the closed end limits the lining member 2 to prevent the lining member 2 from being removed from the closed end of the pipe sleeve 5.

[0046] The method of unsealing the above seal is to use a screwdriver to penetrate the plastic film structure and touch the lining member 2, and apply force so that the lining member 2 squeezes each of the limiting pieces 10, and the limiting pieces 10 are deformed and return to the hole on the clamping member 3, so that the lining member 2 further squeezes each of the hooks 11, so that each of the hooks 11 is deformed and each of the hooks 11 is separated from the ring groove of the screw 4 nut. At the same time, after the lining member 3 passes through each of the limiting pieces 10, each of the limiting pieces 10 returns to its original position under the action of elastic force, so that the lining member 2 is stuck between each of the limiting pieces 10 and each of the hooks 11. By pulling the screwdriver or the sealing cap 1, the entire sealing cap 1 is separated from the pipe sleeve 5, and the seal is unsealed.

[0047] In this embodiment, at least one of the lining members 2 can be accommodated between the hook 11 and the limiting piece 10 , so as to ensure that the lining member 2 completely passes through the position of each limiting piece 10 .

[0048] In this embodiment, an axial through hole 8 is formed on the lining member 2, and the diameter of the through hole 8 is smaller than the diameter of the nut, so as to prevent a tool such as a screwdriver from reaching into the nut to rotate the screw 4 and loosen the screw 4.

[0049] Each seal on the electric energy meter will have a two-dimensional code laser-printed on the plastic film structure at the closed end of the sealing cap 1 to ensure that the information of the electric energy meter can be read by scanning. At the same time, it has the effect of sealing to prevent unauthorized unsealing. The electric energy meter loses information after unsealing and will be recalibrated and inspected. The plastic film structure used at the closed end in this embodiment has a thickness of 0.5mm to 0.6mm to facilitate the passage of the screwdriver. At the same time, a chip can be provided between the sealing cap 1 and the lining member 2. The chip has the same information as the above-mentioned two-dimensional code, thereby protecting the chip and facilitating the external identification gun (scanning gun) to read its information. When the sealing cap in this application is removed, the chip is destroyed to ensure the effectiveness of the seal.

[0050] As those skilled in the art should understand, in the present application, when the anti-theft seal assembly is applied to an electric energy meter, a mounting hole is provided on the electric energy meter, and the mounting hole can accommodate the sealing cap 1, so the sealing cap 1 can seal the screw 4 without using the pipe sleeve 5. When the required installation position is a plane, the pipe sleeve 5 is used to provide an accommodation space for installing the sealing cap 1, thereby achieving the sealing of the screw 4.

[0051] In a third aspect, a method for using an anti-theft seal assembly is provided, comprising: a sealing process, assembling a seal sleeve, installing the seal sleeve and the screw 4 to a predetermined position; an unsealing process, using a disassembly tool to break the seal cap 1, separating the seal sleeve from the screw 4, removing the seal cap 1, and completing the unsealing.

[0052] Specifically, during the sealing process, firstly, the pipe sleeve 5 is installed on the electric energy meter using the screw 4, and then the lining member 2 and the clamping member 3 are assembled into the sealing cap 1 in sequence, and finally the assembled sealing cap 1 is buckled into the pipe sleeve 5, and the clamping member 3 is clamped on the screw 4 to complete the sealing; during the unsealing process, firstly, the sealing cap 1 is broken by the disassembly tool, and the disassembly tool pushes the lining member 2 to separate the clamping member 3 from the screw 4, and removes it from the sealing cap 1 to complete the unsealing. It should be understood that the assembly of the sealing cap 1, the lining member 2 and the clamping member 3 can be directly assembled in the factory as a sealing cover, and when the sealing is implemented, it is directly pressed onto the screw 4 as a whole, which is convenient for rapid automation implementation.

[0053] The anti-theft sealing assembly provided in the present application forms a good sealing effect through the clamping connection between the clamping part 3 and the screw 4 and the closure of the closed end of the sealing cap 1. It can also be achieved by using a screwdriver to poke the sealing cap 1 to separate the sealing cap 1 from the screw 4, and then pulling out the screwdriver to take out the sealing cap 1, thereby achieving rapid sealing and unsealing of the electric energy meter, simplifying the sealing and unsealing operations, and being able to realize automated sealing and unsealing operations, saving time and labor costs.
