Description

Technical Field

[0001] This utility model relates to the field of power instrument technology, specifically to a power measurement and control instrument. Background Technology

[0002] Intelligent power measurement and control instruments have functions such as accurate power parameter measurement, power quality parameter monitoring and analysis, power energy statistics, over-limit alarm, extreme value recording, and event sequence recording. Through I / O modules, they enable monitoring of field equipment status, remote control, and alarm output.

[0003] In practical applications, most common power monitoring and control instruments are installed on the cabinet doors of control cabinets. To accommodate instrument installation, the cabinet doors are specially designed with square holes for instrument insertion. When installing power monitoring and control instruments, bolts are commonly used to firmly secure them to the cabinet door. However, it must be pointed out that this traditional installation method reveals many inconveniences in actual operation. When it comes to disassembling and assembling power monitoring and control instruments, the process of fixing them with bolts is extremely cumbersome. Especially the lower bolts, because they are obstructed by the installed power monitoring and control instruments, operators have limited operating space and cannot easily access and tighten the screws. This not only greatly increases the difficulty of operation and prolongs the time required for disassembly and assembly, but may also lead to accidental damage to the instruments or control cabinet during the disassembly and assembly process due to the inconvenience of operation.

[0044] Refer to the instruction manual appendix Figure 1-7 A power measurement and control instrument, comprising:

[0045] The instrument host consists of a host body 1 and an instrument panel 2.

[0046] A support structure is provided on the instrument host and is used to fix the instrument host. The support structure includes a limiting groove 3 opened on the upper and lower sides of the host body 1, a control slider 4 slidably connected inside the limiting groove 3, a support plate 5 rotatably connected to one end of the control slider 4, a support connecting rod 6 provided between the support plate 5 and the limiting groove 3, one end of the support connecting rod 6 rotatably connected inside the limiting groove 3, and the other end of the support connecting rod 6 rotatably connected to the support plate 5.

[0047] A first elastic element 7 is provided between the control slider 4 and the limiting groove 3. The first elastic element 7 is used to pull the control slider 4 to slide towards the instrument panel 2. In this embodiment, the first elastic element 7 is a spring that pulls the control slider 4 to slide towards the instrument panel 2. The control slider 4 slides inside the limiting groove 3 to control the support plate 5 to enter the limiting groove 3 or extend out of the limiting groove 3.

[0048] A control structure is provided to control the support plate 5 to extend from inside the limiting groove 3.

[0049] The control structure includes:

[0050] The control ring 8 is slidably connected to the side of the instrument panel 2 near the main body 1, and a second elastic element 9 is provided between the control ring 8 and the instrument panel 2. In this embodiment, the second elastic element 9 is a compression spring, which is used to push the control ring 8 and the instrument panel 2 to separate.

[0051] The control rod 10 is fixedly connected to the control ring 8. The support plate 5 has a control groove 11 that cooperates with the control rod 10 at the end away from the control slider 4. The control rod 10 is inserted into the control groove 11, which restricts the support plate 5 inside the limiting groove 3.

[0052] The control lever 10 is designed as a right-angled trapezoid to facilitate the removal of the device from the cabinet door.

[0053] In the initial state, under the action of the second elastic element 9, the control ring 8 and the instrument panel 2 are pushed apart; the control lever 10 is inserted into the control groove 11, and the support plate 5 is restricted inside the control groove 11;

[0054] During use, the instrument host is installed into the pre-drilled mounting hole in the control cabinet door. During installation, the control ring 8 first contacts the cabinet door, and then pushes the instrument host towards the cabinet door, thereby compressing the second elastic element 9, so that the instrument panel 2 and the control ring 8 are in contact. This causes the control ring 8 to drive the control rod 10 to slide out from inside the control slot 11. Then, under the action of the first elastic element 7, the control slider 4 is pulled to slide towards the instrument panel 2. At this time, under the action of the support connecting rod 6, the end of the support plate 5 away from the control slider 4 is pushed upward until the first elastic element 7 pulls the control slider 4 to slide until the end of the support plate 5 away from the control slider 4 is in contact with the cabinet door, and then the instrument host is fixed in the current position.

[0055] When disassembly is required, pull the control slider 4 away from the instrument panel 2 until the support plate 5 is submerged in the limiting groove 3. At this time, the support plate 5 and the inclined edge of the control rod 10 will contact each other. Then slide the control rod 10 towards the instrument panel 2 until the support plate 5 is submerged in the limiting groove 3. Under the action of the second elastic element 9, the control rod 10 will be pushed into the control groove 11, which will restrict the support plate 5 to the current position. At this time, the instrument host can be removed from the cabinet door.

[0056] The self-locking structure is used to limit the position of the control slider 4;

[0057] Self-locking structures include:

[0058] Limiting teeth 13, multiple limiting teeth 13 are symmetrically arranged on both sides of the limiting groove 3, the limiting teeth 13 are distributed longitudinally along the limiting groove 3, and the cross section of the limiting teeth 13 is set as a right triangle;

[0059] Limiting blocks 14 are slidably connected to both sides of the control slider 4, and a third elastic element 15 is provided between the limiting blocks 14 and the control slider 4. In this embodiment, the third elastic element 15 uses a spring to push the limiting blocks 14 to slide inside the control slider 4. A triangular block 16 that cooperates with the limiting teeth 13 is fixedly connected to one end of the limiting blocks 14 near the limiting teeth 13. The third elastic element 15 is used to push the limiting blocks 14 to move towards the limiting teeth 13, so that the triangular block 16 is locked between two adjacent limiting teeth 13.

[0060] In the initial state, under the action of the third elastic element 15, the limiting block 14 is pushed to slide towards the limiting tooth 13 until the inclined surface of the triangular block 16 and the inclined surface of the limiting tooth 13 are in contact. With this setting, when the control slider 4 is pulled towards the instrument panel 2, the inclined surface of the limiting tooth 13 pushes the triangular block 16 and the limiting block 14 to move away from the limiting tooth 13. When the control slider 4 slides to the appropriate position, under the action of the third elastic element 15, the limiting block 14 is pushed to slide towards the limiting tooth 13, so that the straight edge of the limiting tooth 13 and the straight edge of the triangular block 16 are in contact, thereby preventing the control slider 4 from sliding away from the instrument panel 2.

[0061] The unlocking mechanism is used to control the limit block 14 to move away from the limit tooth 13, so that the triangular block 16 and the limit tooth 13 are separated.

[0062] The unlocking structure includes:

[0063] Guide groove 17 is formed at both ends of control slider 4;

[0064] Guide shaft 18 is fixedly connected to limit block 14 and slidably connected inside guide groove 17;

[0065] When in use, the limit block 14 slides inside the control slider 4, and the guide shaft 18 slides inside the guide groove 17.

[0066] Unlocking slide 19 is slidably connected to control slider 4; control slider 4 is provided with a sliding groove, and unlocking slide 19 is fixedly connected with a slide rail that is slidably connected to the sliding groove, so that unlocking slide 19 can slide on control slider 4 towards or away from instrument panel 2.

[0067] Drive slot 20 is provided at both ends of unlocking slide plate 19 and is inclined. Guide shaft 18 is slidably connected inside drive slot 20.

[0068] In use, by pulling the unlocking slide plate 19 away from the instrument panel 2, the guide shaft 18 slides inside the drive groove 20. Under the guidance of the drive groove 20, the limit block 14 is pulled to slide closer to the control slider 4, so that the triangular block 16 and the limit tooth 13 are disengaged, thereby allowing the control slider 4 to be pulled away from the instrument panel 2, so that the support plate 5 can be inserted into the limit groove 3.

[0069] A buffer pad 12 is fixedly connected to the side of the control ring 8 near the main body 1. The buffer pad 12 is set between the control ring 8 and the cabinet door. This arrangement makes the device more stable.

[0070] Multiple rubber strips 21 for increasing friction are fixedly connected to the unlocking skateboard 19, which makes it easier to push the unlocking skateboard 19.

[0071] An elastic pad 22 is fixedly connected to the end of the support plate 5 away from the control slider 4. This arrangement ensures that the elastic pad 22 fits against the cabinet door, thereby improving the stability of the support plate 5.

[0072] Multiple grooves 23 are provided on the elastic pad 22 to increase friction.

[0073] This device improves the stability of the fixed instrument host by adding a support plate 5, which is supported at the rear end of the main body 1, and the other end of the support plate 5 is supported on the cabinet door.

[0074] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
