For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] As shown in the accompanying drawings Figure 1 to the accompanying drawings Figure 4 :

[0026] The utility model provides a pointer type voltmeter convenient to maintain, including pointer type voltmeter main part 1, occlusion sliding groove 2, occlusion fixed buckle 3, occlusion protruding 4 and cabinet 5, the pointer type voltmeter main part 1 two surfaces are set up respectively with occlusion sliding groove 2, every occlusion sliding groove 2 with occlusion fixed buckle 3 sliding installation is together in, wherein occlusion fixed buckle 3 with the occlusion protruding 4 of the groove wall setting is together occlusion, every occlusion sliding groove 2 is provided with a plurality of occlusion protruding 4, pointer type voltmeter main part 1 is inserted in the opening position of cabinet 5 through setting, and is fixed with the occlusion protruding 4 of occlusion fixed buckle 3 in cabinet 5.

[0027] Further, the "T" type groove is set up as occlusion sliding groove 2 on the pointer type voltmeter main part 1, and this design is ingeniously located on the two opposite parallel surfaces of voltmeter main part. This "T" type groove structure not only enhances the stability of sliding, but also provides accurate guidance for occlusion fixed buckle 3.

[0028] Further, a plurality of transverse distribution occlusion protruding 4 are carefully set in the occlusion sliding groove 2, and the cross section design thereof is a right triangle. This configuration ensures that a stable occlusion relationship can be formed between the occlusion protruding 4 and the occlusion strip 34, thereby effectively preventing the voltmeter from loosening or shifting during use.

[0029] Further, the occlusion fixed buckle 3 includes a sliding block seat 31, a fixed clamping head 32, a strip groove 33, an occlusion strip 34 and a fastener 35. The sliding block seat 31 can freely slide along the occlusion sliding groove 2, while the fixed clamping head 32 is in close contact with the surface of the cabinet 5, ensuring the stable connection of the voltmeter and the cabinet. The occlusion strip 34 is fixed in the strip groove 33 by the fastener 35, so that the strip can stably participate in the occlusion process.

[0030] Further, the fixed clamping head 32 not only closely fits the surface of the cabinet 5, but also realizes linear motion along the occlusion sliding groove 2 through the sliding block seat 31. This design makes the installation and removal process of the voltmeter more smooth, and also ensures the stability and accuracy of the voltmeter during installation.

[0031] Further, the occlusion strip 34 is made of spring steel as a whole. The selection of this material enables the strip to deform as necessary in the occlusion sliding groove 2 and the strip groove 33 area to adapt to different installation conditions. At the same time, the elasticity of spring steel ensures that the occlusion strip 34 can maintain a stable occlusion force during long-term use.

[0032] Further, the snap-in strip 34 includes a strip body 341, a snap-in protrusion 342 and an unlocking end 343, the strip body 341 is formed with the snap-in protrusion 342 and the unlocking end 343 by bending process. The snap-in protrusion 342 can form a stable snap-in relationship with the snap-in protrusion 4, while the unlocking end 343 allows the staff to achieve the unlocking separation of the snap-in protrusion 342 and the snap-in protrusion 4 by a simple dialing action, so as to easily complete the disassembly of the voltmeter.

[0033] Further, one end of the strip body 341 is firmly installed in the snap-in groove 33 of the slider seat 31 by the fastener 35, and the other end extends outside and is bent to form the unlocking end 343. This design enables the staff to easily achieve the unlocking separation of the snap-in protrusion 342 and the snap-in protrusion 4 by dialing the unlocking end 343 when disassembling the voltmeter, greatly improving the convenience and efficiency of maintenance work.

[0034] The working principle is as follows: first, when installing the pointer voltmeter body 1:

[0035] Align the pointer voltmeter body 1 with the pre-opened opening position of the cabinet 5, ensure that the voltmeter body 1 matches the installation space inside the cabinet 5. Gently push the voltmeter body 1 to gradually insert into the cabinet 5 along the opening position. When the voltmeter body 1 slides to the predetermined position, install two snap-in fixing buckles 3, the snap-in fixing buckles 3 (specifically the slider seat 31 and the fixed clamping head 32 thereon) will slide along the direction of the snap-in sliding groove 2. At this time, the snap-in strip 34 (especially the snap-in protrusion 342 thereon) in the snap-in fixing buckle 3 will meet and snap with the snap-in protrusion 4 arranged on the groove wall of the snap-in sliding groove 2. Since the cross section of the snap-in protrusion 4 is designed as a right triangle, the snap-in strip 34 will deform under the action of spring steel to adapt to the shape of the snap-in protrusion 4. Once the snap-in strip 34 completely snaps with the snap-in protrusion 4 at the appropriate position, the fixed clamping head 32 will be in contact with the surface of the cabinet 5, and the voltmeter body 1 will be firmly fixed on the cabinet 5. At this time, the close contact of the fixed clamping head 32 with the surface of the cabinet and the stable snap of the snap-in strip 34 with the snap-in protrusion ensure the stability and safety of the voltmeter.

[0036] When the pointer voltmeter body 1 fails and needs to be disassembled:

[0037] The staff first finds the unlocking end 343 on the clamping strip 34. Since the unlocking end 343 is an end of the clamping strip body 341 extended outside and bent, it is easy to be identified and touched. By simply pushing the unlocking end 343, the staff can make the clamping strip 34 deformed, so that the clamping convex 342 on the clamping strip 34 is separated from the clamping convex 4. This unlocking process does not need to use any additional tools, and is very convenient. Once the clamping convex 342 is unlocked and separated from the clamping convex 4, the unlocked clamping buckle 3 is pulled out, and when the two clamping buckles 3 are pulled out, the voltmeter body 1 is no longer fixed on the cabinet body 5. At this time, the staff can easily pull out the voltmeter body 1 from the opening of the cabinet body 5, so as to complete the disassembly work.

[0038] The technical scheme of the utility model, or the technical scheme of the utility model inspires the person skilled in the art to design similar technical scheme, and reach the above technical effect, all fall into the protection scope of the utility model.
