Description

Technical Field

[0001] The present invention relates to the technical field of electrical accessories, and particularly relates to a temporary mobile distribution box for construction and an installation method thereof. Background Art

[0002] During the construction operation process, the distribution box plays an important role. At the same time, it has the characteristics of being convenient to carry and install, and is widely used in the construction operation site. The functions of the distribution box in the construction operation include the following points: reasonably distributing electric energy; facilitating the opening and closing operation of the circuit; having a high safety protection level and being able to intuitively display the conduction state of the circuit.

[0003] Since most of the construction is outdoors, for the support installation height of the distribution box, Article 6.2.8 of the Code for Acceptance of Construction Quality of Building Electrical Engineering GB50303-2002 stipulates that the installation height (bottom edge from the ground) of the lighting distribution box should not be less than 1.5m, and the lighting distribution board should not be less than 1.8m. The existing support installation methods generally use welded steel structure brackets for support erection. Its installation height cannot be reasonably adjusted according to the use scenario. At the same time, for some uneven places, additional inclined supports need to be added to ensure the stability of the installation support, which increases the time consumption of installation wiring before the operation and is not convenient to use. Summary of the Invention

[0004] Aiming at the problems in the above technical background, the purpose of the present invention is to provide a temporary mobile distribution box for construction and an installation method thereof, which solves the problems that the existing installation height of the distribution box cannot be flexibly adjusted and cannot meet the requirements of multi-scenario erection mentioned in the background art.

[0005] In order to achieve the above purposes, the technical solution adopted by the present invention is as follows:

[0006] A temporary mobile distribution box for construction, including a distribution box. U-shaped sliders are symmetrically and slidably clamped on both sides of the distribution box. Support legs are symmetrically and rotatably installed at the bottoms of both ends of the U-shaped sliders. A U-shaped frame for lifting is installed in the middle of the two U-shaped sliders. At the same time, a rotation lock mechanism for controlling the sliding of the U-shaped sliders is installed at the connection between the U-shaped frame and the U-shaped sliders; a height-adjustable lifting lock structure is installed at the center of the bottom of the distribution box. Four groups of link telescopic members are symmetrically installed at the center of the bottom of the distribution box and facing the four corners. The lifting lock structure is used to control the four groups of link telescopic members to horizontally extend and contract outward from the center of the bottom of the distribution box to the four corners, and at the same time, the link telescopic members are used to control the opening and closing support angles of the support legs.

[0007] In the above technical solution, the U-shaped frame is used to push the U-shaped sliders on both sides. The U-shaped sliders drive the support legs at the bottom to expand and contract. The lifting and locking structure controls the expansion and contraction of the link telescopic members at the four corners to control the support angles of the four groups of support legs. After the adjustment is completed, the U-shaped frame is rotated to drive the rotation locking mechanism to lock the U-shaped sliders relative to the distribution box, thereby realizing the installation steps. Through the above structure, the installation height and support angle can be adjusted, making the installation more stable. At the same time, it can adapt to various installation environments, is convenient to adjust, and shortens the installation time.

[0008] Further, concave chutes are symmetrically arranged at the four corners of the distribution box. The two ends of the U-shaped slider are respectively inserted into the front and rear chutes on one side. Protrusions for preventing the U-shaped slider from slipping out are symmetrically arranged on the upper and lower sides of both sides of the distribution box. The inner sides of the two ends of the U-shaped frame are respectively connected to the middle parts of the U-shaped sliders on both sides through a rotation locking mechanism. At the same time, anti-slip tooth plates for cooperating with the rotation locking mechanism are symmetrically and concavely installed in the middle parts of both sides of the distribution box.

[0009] Furthermore, the rotation locking mechanism includes a rotating shaft. A spiral groove is arranged on the shaft surface of the rotating shaft. The rotating shaft is inserted into the middle part of the U-shaped slider. At the same time, the top of the insertion hole of the rotating shaft communicates with the insertion tooth groove penetrating through the inner side of the U-shaped slider. A driving plug-in part that axially slides along with the rotation of the rotating shaft and one end of which inserts into or disengages from the anti-slip tooth plate is installed in the insertion tooth groove.

[0010] Furthermore, the driving plug-in part includes a sliding insertion block. The bottom of the sliding insertion block is provided with a concave surface that fits the shaft surface of the rotating shaft. An insertion rod inserted into the spiral groove is fixedly installed on the concave surface. The inner side end of the sliding insertion block is provided with insertion teeth for cooperating with the anti-slip tooth plate.

[0011] Furthermore, in the locked state, the top end of the U-shaped frame rotates towards the distribution box, and the locking rotation angle is set by setting the pitch of the spiral groove.

[0012] Further, the lifting and locking structure includes a fixed column, a sliding plate slidably installed on the fixed column, and an elastic locking member installed on the fixed column to control the sliding of the sliding plate. Concave grooves are symmetrically arranged on the column surface of the fixed column, and the elastic locking member is installed in the concave grooves. The elastic locking member is an elastic locking bar. Card slots are evenly arranged on the outer side surface of the elastic locking bar. The middle part of the sliding plate is installed on the fixed column through a through groove, and an annular inner protrusion for locking and cooperating with the card slots is arranged in the middle of the through groove. One end of the link telescopic member is respectively hinged to the four corners of the sliding plate.

[0013] Furthermore, a convex block convenient for pressing is connected to the outer side surface of the top end of the elastic locking bar.

[0014] Further, the connecting rod telescopic member includes a first driving plate. One end of the first driving plate is hinged to a second driving plate. The other end of the first driving plate is rotatably installed on a side surface of a corner of the sliding plate. The second driving plate is installed at the bottom of the distribution box through a slide rail. The sliding direction of the second driving plate is from the center of the bottom of the distribution box to a corner. A cover plate for preventing the second driving plate from tilting is installed at the top of the outer side of the slide rail. A columnar anti - detachment block is installed at the outer end of the second driving plate.

[0015] Further, the top end of the support leg is rotatably installed at the bottom of one end of the U - shaped slider through a rotating head. A T - shaped groove with a narrow - side opening facing the center of the distribution box is provided on the support leg. The outer end of the second driving plate is inserted into the T - shaped groove. At the same time, the anti - detachment block is located in the wide groove inside the T - shaped groove.

[0016] An installation method for a temporary mobile distribution box for construction includes the following steps:

[0017] S1. Push and control the two U - shaped sliders on both sides to slide relative to the distribution box through the U - shaped frame. The two U - shaped sliders drive the four support legs to extend to the length at a set support angle.

[0018] S2. Unlock the up - and - down sliding of the sliding plate by pressing the elastic lock bar. Control the sliding plate to slide upward to push the end of the first driving plate to slide from the center of the bottom of the distribution box to the four corners. The first driving plate pushes the second driving plate to extend outward. The second driving plate pushes the support leg to extend outward through the anti - detachment block at the outer end, so as to control the opening and closing support angle of the support leg.

[0019] S3. After the support angle of the support leg is adjusted, rotate the U - shaped frame to drive the rotating shaft to push the insertion rod and the sliding insertion block to slide inward, and the insertion teeth are inserted into the anti - slip tooth plate to achieve sliding locking.

At the same time, a rotation lock mechanism for controlling the sliding of the U-shaped slider is installed at the connection between the U-shaped frame and the U-shaped slider; at the center of the bottom of the distribution box, a height-adjustable lifting lock structure is installed. Four sets of link telescopic members are symmetrically installed at the center of the bottom of the distribution box and facing the four corners. The lifting lock structure is used to control the horizontal telescoping of the four sets of link telescopic members towards the outer sides of the four corners of the distribution box. At the same time, the link telescopic members are used to control the opening and closing support angles of the support legs. By pushing the U-shaped sliders on both sides through the U-shaped frame, the U-shaped sliders drive the support legs at the bottom to expand and contract. By controlling the extension of the link telescopic members at the four corners through the lifting lock structure, the support angles of the four sets of support legs are controlled. After the adjustment is completed, by rotating the U-shaped frame to drive the rotation lock mechanism, the U-shaped slider is locked relative to the distribution box, thereby realizing the installation steps. Through the above structure, the installation height and support angle can be adjusted, making the installation more stable.

[0032] The following will describe in detail the specific implementation mode of the present invention in conjunction with the accompanying drawings. It should be understood that the specific implementation mode described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0033] Embodiment 1

[0034] As Figures 1-9 shown, a temporary mobile distribution box for construction includes a distribution box 1. Concave chutes 102 are symmetrically arranged at the four corners of the distribution box 1. The two ends of the U-shaped slider 2 are respectively inserted into the front and rear chutes 102 on one side. Protrusions 101 for preventing the U-shaped slider 2 from slipping out are symmetrically arranged above and below the two sides of the distribution box 1. The protrusions 101 are integrally formed. By setting the protrusions 101, the U-shaped slider 2 is prevented from sliding out. The thickness of the top plate of the U-shaped slider 2 is the same as the width of the protrusion 101. The inner sides of the two ends of the U-shaped frame 3 are respectively connected to the middle parts of the two sides of the U-shaped slider 2 through a rotating lock mechanism. At the same time, anti-slip tooth plates 103 for cooperating with the rotating lock mechanism are symmetrically and concavely installed in the middle parts of the two sides of the distribution box 1. The two sides of the distribution box 1 are symmetrically and slidably clamped with U-shaped sliders 2. Support legs 6 are symmetrically and rotatably installed at the bottoms of the two ends of the U-shaped slider 2. A U-shaped frame 3 for lifting is installed in the middle parts of the two U-shaped sliders 2;

[0035] At the same time, a rotating lock mechanism for controlling the sliding of the U-shaped slider 2 is installed at the connection between the U-shaped frame 3 and the U-shaped slider 2. The rotating lock mechanism includes a rotating shaft 4. A spiral groove 41 is arranged on the shaft surface of the rotating shaft 4. The rotating shaft 4 is inserted into the middle part of the U-shaped slider 2. At the same time, the top of the insertion hole of the rotating shaft 4 communicates with the tooth insertion groove 21 penetrating the inner side of the U-shaped slider 2. A driving plug-in for axially sliding one end to insert into or disengage from the anti-slip tooth plate 103 along with the rotation of the rotating shaft 4 is installed in the tooth insertion groove 21. The driving plug-in includes a sliding insertion block 5. A concave surface 51 that fits the shaft surface of the rotating shaft 4 is arranged at the bottom of the sliding insertion block 5. An insertion rod 53 inserted into the spiral groove 41 is fixedly installed on the concave surface 51. An inserted tooth 52 for cooperating with the anti-slip tooth plate 103 is arranged at the inner side end of the sliding insertion block 5. During the rotation of the rotating shaft 4, the insertion rod 53 is axially pushed through the spiral groove 41. When moving inward, the inserted tooth 52 at the inner side end of the sliding insertion block 5 is inserted into the anti-slip tooth plate 103 to prevent the U-shaped slider 2 from sliding;

[0036] At the center of the bottom of the distribution box 1, a lifting and locking structure with adjustable height is installed. Four groups of link telescopic members are symmetrically installed at the center of the bottom of the distribution box 1 and facing the four corners. The lifting and locking structure is used to control the horizontal telescoping of the four groups of link telescopic members to the outside of the four corners of the distribution box 1. At the same time, the link telescopic members are used to control the opening and closing support angles of the support legs 6.

[0037] Installation steps: Reel in the wire. Push the U-shaped sliders 2 on both sides through the U-shaped frame 3. The U-shaped sliders 2 drive the telescoping of the support legs 6 at the bottom. Then, control the telescoping of the link telescopic members at the four corners through the lifting and locking structure to control the support angles of the four groups of support legs 6. After adjustment, finally, drive the rotation locking mechanism by rotating the U-shaped frame 3 to lock the U-shaped slider 2 relative to the distribution box 1, thus realizing the installation steps. Through the above structure, the installation height and support angle can be adjusted, making the installation more stable. At the same time, it can adapt to various installation environments, is convenient to adjust, and shortens the installation time.

[0038] As Figure 3 shown, in the locked state, the top of the U-shaped frame 3 rotates towards the distribution box 1. Set the locking rotation angle by setting the pitch of the spiral groove 41. Generally, when rotating 30 - 60 degrees, the inner end insert teeth 52 of the sliding plug 5 are pushed into the anti-slip tooth plate 103. Due to the gravity of the U-shaped frame 3, it will be automatically locked and prevent rotation, and at the same time, unlocking is convenient.

[0039] As Figure 8 、 9 shown, the lifting and locking structure includes a fixed column 7, a sliding plate 9 slidably installed on the fixed column 7, and an elastic locking member installed on the fixed column 7 to control the sliding of the sliding plate 9. The fixed column 7 is fixedly connected to the center of the bottom of the distribution box 1 by welding. Symmetrically concave grooves 71 are provided on the column surface of the fixed column 7, and elastic locking members are installed in the grooves 71. The elastic locking members are elastic locking bars 8. Uniformly arranged card slots 81 are provided on the outer side surface of the elastic locking bar 8. The middle part of the sliding plate 9 is installed on the fixed column 7 through a through groove 91, and a ring-shaped inner protrusion 92 that is locked and matched with the card slot 81 is provided in the middle of the through groove 91. One end of each of the four groups of link telescopic members is hinged to the four corners of the sliding plate 9. In the unlocked state, by pressing the elastic locking bar 8, the card slot 81 is retracted into the groove 71, and at this time, the sliding plate 9 can slide up and down.

[0040] As Figure 8 、 9 shown, a convex block for easy pressing is connected to the outer side surface of the top end of the elastic locking bar 8. By setting the convex block, it is convenient to press the elastic locking bar 8 to retract into the groove 71.

[0041] As Figure 2 、 8As shown in FIGS. 9, the link telescopic member includes a first driving plate 10. One end of the first driving plate 10 is hinged to a second driving plate 11. The other end of the first driving plate 10 is rotatably installed on a side surface of a corner of the sliding plate 9. The second driving plate 11 is installed at the bottom of the distribution box 1 through a slide rail 13. The sliding direction of the second driving plate 11 is from the center of the bottom of the distribution box 1 to a corner. A cover plate 14 for preventing the second driving plate 11 from tilting is installed at the top of the outer side of the slide rail 13. A columnar anti-disengagement block 12 is installed at the outer end of the second driving plate 11. During the up and down sliding of the sliding plate 9, the first driving plate 10 pushes and pulls the second driving plate 11 to perform telescopic sliding towards the four corners of the bottom of the distribution box 1. The top end of the support leg 6 is rotatably installed at the bottom of one end of the U-shaped slider 2 through a rotating head 61. A T-shaped groove 62 with a narrow side opening facing the center of the distribution box 1 is provided on the support leg 6. The outer end of the second driving plate 11 is inserted into the T-shaped groove 62. At the same time, the anti-disengagement block 12 is located in the wide groove inside the T-shaped groove 62. The second driving plate 11 pushes the support leg 6 to expand outwards through the anti-disengagement block 12 at the end, thereby realizing the function of controlling the support angle of the support leg 6.

[0042] At the same time, the present invention also proposes an installation method for a temporary mobile distribution box for construction, which includes the following steps: S1. Push and control the two U-shaped sliders 2 on both sides to slide relative to the distribution box 1 through the U-shaped frame 3. The two U-shaped sliders 2 drive the four groups of support legs 6 to extend to the length of the set support angle, and the set length should be greater than or equal to the length of the set inclination angle; S2. Unlock the up and down sliding of the sliding plate 9 by pressing the elastic lock bar 8. Push the end of the first driving plate 10 to slide from the center of the bottom of the distribution box to the four corners by controlling the upward sliding of the sliding plate 9. The first driving plate 10 pushes the second driving plate 11 to extend outwards. The second driving plate 11 pushes the support leg 6 to extend outwards through the anti-disengagement block 12 at the outer end, so as to control the opening and closing support angle of the support leg 6. S3. After the support angle of the support leg is adjusted, rotate the U-shaped frame to drive the rotating shaft to push the insertion rod and the sliding insertion block to slide inwards, and the insertion teeth are inserted into the anti-slip tooth plate to realize sliding locking.
