[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Example 1: This utility model provides the following... Figures 1 to 5 The illustrated guide rail type electricity meter includes a meter body 1 and a fixing plate 2. The fixing plate 2 is a rectangular strip used for fixing to an installation location such as a wall. A slide rail 4 is fixedly installed on the fixing plate 2 along its length, and two tracks are formed on the slide rail 4 along the length of the fixing plate 2.
[0024] The two tracks are symmetrically arranged, forming an I-shaped cross-section for the slide rail 4. The openings of the two tracks are opposite to each other and are both set along the width direction of the fixing plate 2. The two tracks pass through the slide rail 4 along the length direction of the fixing plate 2.
[0025] The back of the watch body 1 is provided with a slide groove 13 that slides with the slide rail 4. The opening of the slide groove 13 is horizontally facing the rear of the watch body 1, and the slide groove 13 passes through the watch body 1.
[0026] The inside of the dial body 1 has four guide grooves 14 and four mounting grooves 6, which correspond one-to-one. The opening of each mounting groove 6 faces horizontally towards the rear of the dial body 1.
[0027] The four guide grooves 14 are divided into two groups of two. The two guide grooves 14 in the same group are symmetrical about the slide groove 13. Each guide groove 14 is located between the slide groove 13 and the corresponding mounting groove 6, and each guide groove 14 is connected to the slide groove 13 and the corresponding mounting groove 6.
[0028] Each mounting slot 6 contains a sliding abutment block 9 that engages with and limits the contact with the fixed plate 2. The abutment blocks 9 in the two mounting slots 6 corresponding to the two guide slots 14 in the same group are fixedly connected to the same connecting block 7. The body 1 has a connecting groove for the connecting block 7 to slide, and the connecting groove communicates with the mounting slots 6 where the two abutment blocks 9 connected to the connecting block 7 are located.
[0029] Each connecting block 7 is fixedly equipped with a mating block 8. The body 1 is equipped with a driving component that drives all the abutment blocks 9 to slide along the mounting groove 6. The driving component is connected to the two mating blocks 8 in a transmission manner.
[0030] Specifically, the driving component includes two bolts 5, both of which are rotatably mounted inside the watch body 1, with the heads of both bolts 5 embedded in the front end of the watch body 1. Each bolt 5 corresponds one-to-one with a mating block 8. The threaded section of the shaft of each bolt 5 passes through the connecting groove of the corresponding mating block 8 and is threadedly connected to the corresponding mating block 8. Each mating block 8 has a limiting sliding fit with its corresponding connecting groove.
[0031] Each guide groove 14 has a sliding locking block 11 that engages with the track of the slide rail 4. Each locking block 11 is connected to its corresponding abutment block 9 by a linkage component, and each locking block 11 is engaged with its corresponding abutment block 9 through the linkage component.
[0032] Specifically, the linkage includes a push block 10 with an inclined surface and a return spring 12. The push block 10 is fixed on the locking block 11 and inserted into the mounting groove 6. The abutment block 9 slides against the inclined surface on the push block 10 and engages with the push block 10 through the inclined surface for transmission.
[0033] Two clearance slots communicating with the guide groove 14 are formed inside the dial body 1, and the two clearance slots are symmetrically arranged about the guide groove 14. A reset spring 12 is provided in each clearance slot, which is arranged along the sliding direction of the locking block 11. A pressure block fixedly connected to the locking block 11 is slidably installed in each clearance slot. One end of each reset spring 12 is fixedly connected to the pressure block in the clearance slot, and the other end is fixedly connected to the dial body 1.
[0034] Multiple slots 3 for engaging the abutment block 9 are formed on the fixing plate 2 along the thickness direction. The multiple slots 3 are arranged in two rows at equal intervals along the length direction of the fixing plate 2, and the slide rail 4 is located between the two rows of slots 3.
[0035] Working principle of Example 1: When installing this rail-mounted energy meter, fix the mounting plate 2 to the installation location, such as a wall. Then, mate the slide groove 13 on the meter body 1 with the slide rail 4. After mating, tighten the two bolts 5, which will rotate and push the corresponding mating block 8 to move closer to the mounting plate 2.
[0036] Two mating blocks 8 drive the connected connecting blocks 7 to slide closer to the fixed plate 2, and the two connecting blocks 7 drive the corresponding abutting blocks 9 to slide closer to the fixed plate 2. During this process, multiple abutting blocks 9 push the corresponding push blocks 10 to slide closer to the slide rail 4. All push blocks 10 push the connected locking blocks 11 to slide out of the guide groove 14 and into the corresponding track. During this process, all locking blocks 11 drive the pressure blocks connected to them to compress the corresponding return springs 12.
[0037] Next, push the watch body 1 to slide it along the slide rail 4. While the watch body 1 slides along the slide rail 4, observe whether all the abutment blocks 9 are aligned with their corresponding slots 3. When all the abutment blocks 9 are aligned with their corresponding slots 3, tighten the two bolts 5 again to insert all the abutment blocks 9 into their corresponding slots 3 and engage them. At this time, the abutment blocks 9 restrict the movement of the watch body 1 along the length of the fixing plate 2, and the locking blocks 11 restrict the movement of the watch body 1 along the thickness of the fixing plate 2.
[0038] When it is necessary to remove the watch body 1, turn the two bolts 5 in the reverse direction. The two bolts 5 push the corresponding mating blocks 8 to slide away from the fixing plate 2. The two mating blocks 8 drive the corresponding connecting blocks 7 to slide away from the fixing plate 2. The two connecting blocks 7 drive the corresponding abutting blocks 9 to slide back to the watch body 1 and return to their original positions. During this process, all abutting blocks 9 gradually disengage from the corresponding push blocks 10. When each abutting block 9 has disengaged from the corresponding push block 10, under the elastic force of the return spring 12, all locking blocks 11 slide back to the watch body 1. After all locking blocks 11 have returned to their original positions, the watch body 1 can be removed.
[0039] Example 2: This example is a further optimization of Example 1. In order to further achieve quick assembly and disassembly, elastic rubber pads can be fixedly installed at the end of the locking block 11 away from the push block 10 and at the end of the abutment block 9 away from the connecting block 7.
[0040] The working principle of Embodiment 2: The difference between this principle and Embodiment 1 is that it is not necessary to align the abutment blocks 9 with the slots 3. Instead, after the slide groove 13 mates with the slide rail 4, tightening the two bolts 5 causes all the abutment blocks 9 to engage with their corresponding elastic rubber pads and abut against the fixing plate 2. During this process, the pusher 10 causes all the locking blocks 11 to engage with their corresponding elastic rubber pads, allowing them to abut against the bottom inner wall of the corresponding track.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
