Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable construction technology, specifically to a rapid installation device for cables and wires on construction sites. Background Technology
[0002] Before construction begins, workers need to install temporary power according to the actual situation. Since the wiring is quite complex, quick installation devices are needed to assist in the installation, thereby improving the efficiency of cable and wire laying.
[0003] In the prior art, such as the "Quick Installation Device for Cables and Wires on Construction Sites" disclosed in Chinese Patent CN220358733U, there is an installation part mounted on an aluminum profile. The installation part is detachably mounted on the aluminum profile by screws. The installation part includes a base. Two mounting plates are provided in the middle of the base, and two limiting blocks are arranged opposite to each other between the two mounting plates. The limiting blocks are elastically arranged. A limiting notch is formed between the lower part of the limiting block and the mounting plate. A through notch is provided in the middle of the base. A cable tie moves through the through notch. The through notch is square. The upper edge of the end of the through notch is arc-shaped.
[0004] As described above, although the cable and wire can be quickly installed by means of torsion springs and limiting blocks, the force applied by the two limiting blocks through the torsion springs alone is insufficient to stably fix the cable and wire. When external forces exert pulling or dragging on the cable and wire, the cable and wire may fall off because the pulling force is greater than the force generated by the torsion springs, resulting in poor fixing effect of the installation device. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a fast cable and wire installation device for construction sites that is simple in structure, easy to operate, improves the reliability of cable laying, and improves the efficiency of cable and wire laying.
[0006] The technical solution adopted by this utility model is:
[0007] A rapid installation device for cables and wires at construction sites includes: a base, a positioning seat on the base, and a cable limiting device on the positioning seat;
[0008] The cable limiting device includes two limiting blocks arranged symmetrically on the left and right sides, with the lower parts of the left and right limiting blocks rotatably connected to the positioning seat.
[0009] The cross-section of the limiting block is "U" shaped, and when the upper ends of the left and right limiting blocks are attached, a cable limiting space is formed;
[0010] A U-shaped limiting frame is hinged to the left limiting block, and the free end of the limiting frame is connected to the middle of the limiting block by a pin.
[0011] The bottom of the U-shaped limiting frame is provided with a fixing through hole;
[0012] The right limit block is provided with a sliding groove. When the limit frame is fastened to the right limit block, the fixing through hole is connected to the sliding groove.
[0013] A sliding connection block is provided inside the groove, and the front end of the block can pass through the fixing through hole;
[0014] The positioning seat is equipped with a torsion spring. One end of the torsion spring abuts against the outer wall of the limiting block, and the other end abuts against the base, which is used to drive the limiting blocks on both sides to close.
[0015] Preferably, the positioning seat includes a front limiting plate and a rear limiting plate arranged in parallel front and rear.
[0016] The front limiting plate and the rear limiting plate are respectively fixed with upper support shafts and lower support shafts that are parallel to each other on the left and right sides.
[0017] The limiting block is located between the front limiting plate and the rear limiting plate, and its lower part is provided with a limiting block connecting hole, through which the upper support shaft passes.
[0018] The torsion spring is sleeved on the lower support shaft.
[0019] Preferably, the base is provided with an L-shaped limiting plate, the vertical part of which is fixed to the base and the horizontal part extends to the inner side of the front limiting plate or the rear limiting plate;
[0020] One end of the torsion spring is engaged with the horizontal part of the limiting plate.
[0021] Preferably, the lower support shaft is provided with slots located on both sides of the torsion spring;

[0024] The bottom of the stop block is connected to the bottom of the slide groove via a reset spring. When the stop block is pressed, its front end retracts into the clearance groove.
[0025] Preferably, a blocking frame is provided on the outside of the slide groove to prevent the stop block from falling out of the slide groove.
[0026] Preferably, the outer surface of the limiting block is provided with a first arc surface into which the guide cable slides, and the inner surface is provided with a second arc surface into which the guide cable slides.
[0027] Preferably, the upper surfaces of the front limiting plate and the rear limiting plate are arc surfaces.
[0028] The advantages of this utility model over the prior art are:
[0029] This utility model discloses a rapid cable and wire installation device for construction sites. By setting a limiting frame and a stop block, the two limiting blocks first limit the cable and wire and then provide a secondary limit. When the cable is subjected to external force, a pushing force is applied to the two limiting blocks. Because the limiting frame limits the two limiting blocks, the limiting blocks cannot be unfolded, ensuring the fixing strength of the cable and wire within the device and preventing the cable from easily falling out of the device due to external pulling. This improves the reliability of cable laying and increases the efficiency of cable and wire laying. Attached Figure Description

[0039] The cable limiting device includes two limiting blocks 3 arranged symmetrically on the left and right sides, with the lower parts of the left and right limiting blocks rotatably connected to the positioning seat 2.
[0040] The limiting block 3 has a "7" shaped cross section, and when the upper ends of the left and right limiting blocks are attached, a cable limiting space is formed.
[0041] A U-shaped limiting frame 4 is hinged to the left limiting block, and the free end of the limiting frame 4 is connected to the middle of the limiting block 3 by a pin.
[0042] The bottom of the U-shaped limiting frame 4 is provided with a fixing through hole 5;

[0045] The positioning seat 2 is equipped with a torsion spring 12. One end of the torsion spring 12 abuts against the outer wall 24 of the limiting block 3, and the other end abuts against the base 1, which is used to drive the limiting blocks 3 on both sides to close.
[0046] like Figure 4 The positioning seat 2 includes a front limiting plate and a rear limiting plate arranged in parallel front and rear.
[0047] The front limiting plate and the rear limiting plate are respectively fixed with an upper support shaft 21 and a lower support shaft 11 that are parallel to each other on the left and right sides.
[0048] The limiting block 3 is located between the front limiting plate and the rear limiting plate, and its lower part is provided with a limiting block connecting hole 22, through which the upper support shaft 21 passes.
[0049] The torsion spring 12 is sleeved on the lower support shaft 11.
[0050] like Figure 5 The base 1 is provided with an L-shaped limiting plate 13, the vertical part of which is fixed to the base 1 and the horizontal part extends to the inner side of the front limiting plate or the rear limiting plate.
[0051] One end of the torsion spring 12 is engaged with the horizontal part of the limiting plate 13.
[0052] like Figure 5 The lower support shaft 11 is provided with slots 14 located on both sides of the torsion spring 12;

Because the limiting frame restricts the two limiting blocks, they cannot unfold, ensuring the cable / wire's fixation strength within the device and preventing the cable from easily detaching due to external pulling. This improves the device's effectiveness in securing cables and wires.
