Description

Technical Field

[0001] This utility model relates to the field of low-voltage power grid distribution, specifically a cable branch box with a modular frame structure. Background Technology

[0002] With the development of cable-based power distribution networks, when small-capacity independent loads are concentrated, cable branch boxes can be used to branch and connect cables or electrical appliances.

[0003] Existing cable distribution boxes are mostly installed individually. When multiple cable distribution boxes are needed for complex installation conditions, they cannot be well connected to each other, making the installation of internal wiring harnesses or electrical appliances cumbersome. Furthermore, since the mounting plates inside the cable distribution box are usually fixed to the inner wall of the box, the interior is dimly lit, which makes it inconvenient for workers to install or repair electrical appliances. In addition, the small space inside the box, with various electrical appliances piled up inside, restricts the space available for workers to operate and makes it difficult for them to install electrical appliances. Utility Model Content

[0004] The purpose of this invention is to provide a cable branch box with a modular frame structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A modular frame cable branch box includes: a box body, three sets of positioning frames are equidistantly arranged inside the box body, each of the three sets of positioning frames is provided with a support plate, the support plate is used to install the modular cable structure, and the three sets of support plates are slidably connected to each other.

[0007] The bottom of the enclosure is equipped with a locking assembly that can lock the position of the support plates, keeping the three sets of support plates either away from or close to the enclosure door. When the three sets of support plates are pulled outward, the bottom support plate can drive the lifting assembly inside the enclosure to move, thereby causing the other two sets of support plates to unfold equidistantly in the vertical direction, increasing the distance between the two sets of support plates, so that the operator can install or disassemble the modular cable structure.

[0008] The cable branch box constructed with a modular frame as described above: a mounting bracket is provided on the support plate, the modular cable structure is installed on the mounting bracket, and a slider is provided at one end of the support plate away from the mounting bracket. The slider is slidably connected to a slide rail provided on the positioning frame, and a slide rod is provided on the support plate in the middle position. The slide rod is on the same side as the slider, and a plug-in rod is provided on the other side of the support plate.

[0009] The cable branch box with a modular frame structure as described above: the locking assembly includes wedge blocks, two sets of wedge blocks are symmetrically arranged along the length direction of the slide rail, and each set of wedge blocks is provided with a plug-in tube. The plug-in tube is slidably connected to a fixed rod provided in the box body. A spring is sleeved on the fixed rod, one end of the spring abuts against the box body, and the other end abuts against the plug-in tube.

[0010] The cable branch box with a modular frame structure as described above has a trigger element on the bottom support plate. The trigger element includes a trigger plate fixedly connected to the support plate. On the side of the trigger plate away from the support plate, there is a snap-fit ​​block and a protrusion. The snap-fit ​​block is slidably connected to a snap-fit ​​groove provided in the box body. There are two sets of protrusions. The two sets of protrusions cooperate with the lifting assembly to drive the other two sets of support plates to unfold at equal intervals.

[0011] The cable branch box constructed with a modular frame as described above: the lifting assembly includes a first lifting plate and a second lifting plate that are slidably arranged in the vertical direction of space. The first lifting plate has a fitting groove, and the second lifting plate has a composite groove. The two sets of protrusions are slidably arranged in the fitting groove and the composite groove, respectively.

[0012] The cable branch box constructed with a modular frame as described above: the fitting groove includes a first horizontal groove and a first inclined groove formed on the first lifting plate.

[0013] The cable branch box constructed with a modular frame as described above: the composite channel includes a second horizontal channel and a second inclined channel opened on the second lifting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a locking component, the support plate can be locked in two positions: in the normal state, it prevents the support plate from sliding inside the box; in the maintenance state, it ensures that the support plate is kept on the side closer to the box door where there is more light, preventing shaking during maintenance and providing a favorable environment for maintenance personnel.

[0016] Meanwhile, by setting up lifting components, the upper support plates can be driven to unfold vertically at equal intervals as the support plates slide outward, thereby increasing the distance between two adjacent sets of support plates, thus increasing the maintenance operation space, making it easier for maintenance personnel to carry out maintenance operations, and providing spatial convenience for maintenance personnel.

[0026] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0027] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0028] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0029] Please see Figures 1-8 In this embodiment of the utility model, a cable branch box with a modular frame structure includes:

[0030] The enclosure 1 has three sets of positioning frames 3 arranged at equal intervals inside the enclosure 1. Each of the three sets of positioning frames 3 is provided with a support plate 2. The support plate 2 is used to install the modular cable structure, and the three sets of support plates 2 are slidably connected to each other.

[0031] The bottom of the enclosure 1 is provided with a locking component, which can lock the position of the support plate 2 so that the three sets of support plates 2 are kept away from or close to the door. When the three sets of support plates 2 are pulled outward, the support plate 2 at the bottom can drive the lifting component set in the enclosure 1 to move, thereby driving the other two sets of support plates 2 to unfold equidistantly in the vertical direction, so as to increase the distance between the two sets of support plates 2, so as to facilitate the operator to install or disassemble the modular cable structure.

[0032] For details, please refer to Figure 4 , Figure 8The support plate 2 is provided with a mounting frame 201, and the modular cable structure is installed on the mounting frame 201. Multiple sets of modular cable structures cooperate with each other to realize the branching, connection and circuit control of cable lines. The support plate 2 is provided with a slider 202 at one end away from the mounting frame 201. The slider 202 is slidably connected to the slide rail 301 provided on the positioning frame 3. The support plate 2 in the middle position is provided with a slide rod 15. The slide rod 15 and the slider 202 are on the same side. The other side of the support plate 2 is provided with a plug rod 10. With the cooperation of the plug rod 10 and the slide rod 15, the three sets of support plates 2 can slide in the horizontal direction and slide relative to each other in the vertical direction.

[0033] The locking assembly includes a wedge block 11, and two sets of wedge blocks 11 are symmetrically arranged along the length direction of the slide rail 301. Each set of wedge blocks 11 is provided with a plug tube 12. The plug tube 12 is slidably connected to a fixing rod 14 provided in the housing 1. A spring 13 is sleeved on the fixing rod 14. One end of the spring 13 abuts against the housing 1, and the other end abuts against the plug tube 12.

[0034] Specifically, please refer to Figure 6 , Figure 7 The aforementioned wedge block 11 is configured in the form of a "right-angled trapezoidal structure", and its inclined surface is set as the trigger surface 1101.

[0035] The inner wall of the aforementioned plug-in cylinder 12 is provided with a protrusion 1201, which is slidably disposed in a groove 1401 opened on the outer wall of the fixing rod 14. With the cooperation of the protrusion 1201 and the groove 1401, the wedge block 11 can only descend along the axial direction of the fixing rod 14.

[0036] Specifically, the aforementioned spring 13 is always in a compressed state, pushing the wedge block 11 away from the bottom of the housing 1. At this time, the wedge block 11 is inserted into the slide rail 301. In the initial state, the three sets of support plates 2 are retracted into the housing 1. The vertical surface of the wedge block 11 on the inner side can just block the slider 202, which can prevent the support plate 2 from sliding freely in the housing 1. The distance between the three sets of support plates 2 is at its minimum, so that the housing 1 can protect the mounting bracket 201.

[0037] Further, please refer to Figure 2 , Figure 4 , Figure 5A trigger element is provided on the bottom support plate 2. The trigger element includes a trigger plate 5 fixedly connected to the support plate 2. A snap-fit ​​block 501 and a protrusion 502 are provided on the side of the trigger plate 5 away from the support plate 2. The snap-fit ​​block 501 is slidably connected to the snap-fit ​​groove 8 provided in the housing 1. Two sets of protrusions 502 are provided. The two sets of protrusions 502 cooperate with the lifting component to drive the other two sets of support plates 2 to unfold at equal intervals.

[0038] A snap-fit ​​block 501 is provided on the side of the trigger plate 5 away from the mounting bracket 201. The snap-fit ​​block 501 is slidably disposed in the snap-fit ​​groove 8 provided in the housing 1.

[0039] When the modular cable structure inside the enclosure 1 malfunctions or requires periodic inspection, the enclosure door is opened, and the bottom support plate 2 is pulled outward. The locking block 501 slides in the locking groove 8. Then, all three sets of support plates 2 move outward simultaneously, bringing the modular cable structure on the mounting frame 201 closer to the outside of the enclosure 1 where the light is brighter, so that the inspection personnel can operate on the modular cable structure. During this process, the trigger on the bottom support plate 2 cooperates with the lifting component to drive the upper two support plates 2 to expand upward, thereby increasing the distance between the two support plates 2 and expanding the operating space for the inspection personnel.

[0040] For details, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 The lifting assembly includes a first lifting plate 6 and a second lifting plate 9 that are slidably disposed along the vertical direction of space. The first lifting plate 6 has a fitting groove, and the second lifting plate 9 has a composite groove. The two sets of protruding columns 502 are respectively slidably disposed in the fitting groove and the composite groove.

[0041] Specifically, please refer to Figure 3 , Figure 4 The first lifting plate 6 and the second lifting plate 9 are provided with T-slots 601 on the side away from the mounting frame 201. T-blocks 7 that are fixedly connected to the box body 1 are slidably arranged in the T-slots 601. With the cooperation of the T-blocks 7 and the T-slots 601, the first lifting plate 6 and the second lifting plate 9 can only slide in the vertical direction.

[0042] Furthermore, two sets of moving grooves 901 are provided on the other side of the first lifting plate 6 and the second lifting plate 9. Moving rods 16 are slidably arranged in the moving grooves 901 respectively. The two sets of moving rods 16 are fixedly connected to the two sets of upper support plates 2 respectively. With the cooperation of the moving rods 16 and the moving grooves 901, the support plates 2 can only slide relative to the first lifting plate 6 and the second lifting plate 9 along the depth direction of the box body 1.

[0043] The fitting groove includes a first horizontal groove 602 and a first inclined groove 603 formed on the first lifting plate 6;

[0044] The composite groove includes a second horizontal groove 902 and a second inclined groove 903 formed on the second lifting plate 9;

[0045] In particular, please see Figure 4 The projected length of the first inclined groove 603 in the vertical direction is twice the projected length of the second inclined groove 903 in the vertical direction. The slopes of the first inclined groove 603 and the second inclined groove 903 are the same. In the initial state, the two sets of protruding posts 502 are located at the beginning of the stroke of the first horizontal groove 602 and the second horizontal groove 902, respectively.

[0046] When it is necessary to inspect the modular cable structure, first open the box door, then press down the pressing plate 4, drive the wedge block 11 to descend through the pressing plate 4, and pull out the bottom support plate 2 until the support plate 2 can be pulled out. Then release the pressing plate 4, and the wedge block 11 returns to the initial position.

[0047] As the support plate 2 continues to be pulled outward, the moving rod 16 slides in the moving groove 901, and the slider 202 contacts the trigger surface 1101 of the outer wedge block 11, forcing the wedge block 11 to continue to descend. At this time, the mounting brackets 201 of the upper two layers cross the slide rail 301 and can extend upward normally. At the same time, the two sets of protruding columns 502 move to engage with the first inclined groove 603 and the second inclined groove 903 respectively, and the moving rod 16 moves to the end of the stroke of the moving groove 901.

[0048] Subsequently, when the bottom support plate 2 is pulled further, the two sets of protruding columns 502 cooperate with the first inclined groove 603 and the second inclined groove 903 to drive the upper first lifting plate 6 and the second lifting plate 9 to lift the two layers of support plates 2 upwards. The lifting rate of the uppermost support plate 2 is twice that of the middle support plate 2. When the bottom support plate 2 is pulled to the end of the stroke of the slide rail 301, the wedge block 11 rises rapidly under the action of the spring 13. Then, the vertical surface of the outer wedge block 11 locks the slider 202. At this time, the position of the support plate 2 is fixed in a brighter position, which is convenient for the inspectors to observe the structure on the mounting frame 201. At the same time, the protruding columns 502 move to the end of the stroke of the first inclined groove 603 and the second inclined groove 903 and are fixed in position to increase the distance between the two sets of support plates 2, so as to facilitate the construction operation by the inspectors.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
