[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 An embodiment of the utility model discloses a digital display type ring main unit measurement and control integrated device, the integrated device comprises a body 1 having a convex edge 11, of course, a display screen is arranged on the body 1, so as to display specific numerical signals, the means is prior art, and no further description is given here, the convex edge 11 is of rectangular structure, in addition, grooves 12 are provided on the upper and lower sides of the body 1, and a bracket 2 is fixedly installed on the inner side of the groove 12;

[0023] Among them, the inner side of the bracket 2 is slidably connected to the limiting frame 3, and the limiting frame 3 has a first clamping arm 31 and a second clamping arm 32. The first clamping arm 31 cooperates with the protruding edge 11 to clamp on both sides of the cabinet door, and the second clamping arm 32 slides and clamps with the limiting frame 3.

[0024] In some embodiments, the bracket 2 in the utility model includes two mounting seats 21 and a sliding rod 22 connected between the two mounting seats 21, and a plurality of teeth 23 are provided on the inner side surface of the sliding rod 22. Preferably, the teeth 23 described in this embodiment include a plane portion and an inclined portion, and the inclined portion faces one side of the protruding edge 11. The plane portion is designed to achieve a stop effect, so as to realize the one-way clamping movement of the second clamping arm 32.

[0025] On the basis of the above-mentioned embodiment, the mounting seat 21 in the utility model is in a U-shaped structure, and a mounting hole is opened on the end face of the mounting seat 21. The mounting hole is a countersunk hole. During the specific installation, the two mounting seats 21 are fixed inside the groove 12 by bolts to complete the fixation of the bracket 2.

[0026] Furthermore, in this embodiment, the limiting frame 3 is a U-shaped structure, and the second clamping arm 32 is formed at two bent ends of the U-shaped structure, wherein the second clamping arm 32 is formed at the lower side of the two bent ends of the limiting frame 3, that is, the limiting frame 3 in this embodiment is set as a plastic frame, and the second clamping arm 32 formed on both sides of the limiting frame 3 has a certain deformation ability by virtue of the deformation ability of the plastic, so as to achieve the clamping action;

[0027] Among them, sliding seats 33 are fixedly installed on both sides of the bottom of the limit frame 3, and a groove adapted to the slide rod 22 is formed between the sliding seat 33 and the limit frame 3. Preferably, the slide rod 22 described in this embodiment is an L-shaped structure, and a groove is formed between it and the bottom of the limit frame 3, and the sliding connection with the slide rod 22 is achieved through the groove to realize the sliding of the entire limit frame 3.

[0028] Preferably, in the present embodiment, a slideway for accommodating the slide rod 22 is provided on the side of the second clamping arm 32 , and a shaft rod 34 is fixedly installed in the slideway on the second clamping arm 32 , and the shaft rod 34 is clamped with the teeth 23 .

[0029] That is to say, in this embodiment, since the two ends of the limit frame 3 can be deformed, the second clamping arm 32 can drive the shaft rod 34 to engage with the teeth 23 on the slide rod 22 through the deformation of the two sides of the limit frame 3. When the limit frame 3 needs to be moved, the limit frame 3 is pushed forward and the shaft rod 34 is engaged with the teeth 23 to complete the position limitation of the limit frame 3.

[0030] It should be noted that, in this embodiment, the first clamping arm 31 is a bending plate fixed on the inner side of the limit frame 3, and the bending plate is also set to be a plastic plate so that it has a certain deformation ability. A deformation groove 35 is opened between the bending plate and the two sides of the limit frame 3, and a guiding arc surface 36 is set on the side of the bending plate away from the convex edge 11.

[0031] During installation, firstly, a mounting hole is opened on the ring main cabinet door, and the device is inserted into the mounting hole through the front end of the ring main cabinet door. During this process, the guide arc surface 36 on the first clamping arm 31 contacts the door panel and begins to deform until it retracts to the inner side of the groove 12 and resets and pops out after it moves to the other side of the door panel. The first clamping arm 31 and the convex edge 11 are limited on both sides to complete the clamping of the door panel, thereby completing the convenient installation of the device.

[0032] In addition, since the door panels of the ring network cabinet have different thicknesses, in order to adapt to different door panel thicknesses, the two ends of the limit frame 3 can be pressed to move the second clamping arm 32, and the shaft rod 34 on the second clamping arm 32 is separated from the teeth 23. At this time, the entire limit frame 3 can be freely slid until the first clamping arm 31 contacts the rear side of the door panel to ensure the applicability and stability of the installation.

[0033] In summary, in the utility model, the first clamping arm 31 set on the limit frame 3 is used to cooperate with the convex edge 11 on the body 1 to clamp on both sides of the ring network cabinet door, so as to achieve convenient installation of the device. Secondly, the entire limit frame 3 in the utility model adopts a movable structural design, which can adapt to door panels of different thicknesses. During operation, it is only necessary to press the two ends of the limit frame 3 to move the second clamping arm 32 to separate the shaft rod 34 from the teeth 23, and slide the limit frame 3 until the first clamping arm 31 contacts the rear side of the door panel to ensure the applicability and stability of the installation.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
