Description

Technical Field

[0001] This utility model relates to cable supports, and in particular to a foldable steel frame cable support. Background Technology

[0002] The patent application number "2024218906946" entitled "A Cable Support with Strong Overturning Resistance" is a patent previously applied for by our company. This device can effectively reduce the probability of cable support overturning. In actual use, a dozen to twenty such cable supports need to be set up, and temporary cables need to be moved and repositioned frequently according to the on-site construction conditions. However, the various parts of the cable support are fixed, bulky, and inconvenient to transport. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a foldable steel frame cable support that facilitates folding and transportation while ensuring a reduced overturning rate of the cable support.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A foldable steel frame cable support includes a cable rack, a folding mechanism, and a cable tray;

[0006] The cable rack includes a left sub-frame and a right sub-frame, with the upper ends of the left and right sub-frames connected by cable trays and the lower ends connected by a folding mechanism.

[0007] The folding mechanism includes a first link and a second link. The outer ends of the first link and the second link are fixed with sleeves, which are sleeved with the left subframe or the right subframe. The inner ends of the first link and the second link are hinged together by hinges.

[0008] The cable tray is made of welded steel pipes.

[0009] The outer sections of the steel pipe are coated with a warning reflective layer.

[0010] The cable tray includes a connecting wire and a sleeve; both ends of the connecting wire are fixed on the left or right sub-frame, and the sleeve covers the outer layer of the connecting wire.

[0011] The connecting wire is a steel strand, and the sleeve is a high-temperature resistant glass fiber tube.

[0012] The first link and the second link are locked together by a locking mechanism. The locking mechanism includes a connecting rod, one end of which is fixed to the first link and the other end is fixed to a locking seat. A spring rod is provided on the corresponding second link. The spring rod is connected to the locking block, and the locking block is inserted into or disengaged from the locking seat.

[0013] The locking seat has a locking head connected by a spring inside, and the locking head engages with the groove of the locking block.

[0014] This utility model provides a foldable steel frame cable bracket, which has the following technical advantages:

[0015] 1) By making the cable rack foldable, it is not only easy to move, but also saves space when transporting and storing it after use.

[0016] 2) By setting a locking mechanism, the effect of this device after unfolding is consistent with the effect of fixed connection, both of which can maintain the stability and reliability of the connection and avoid the cable rack from folding and becoming unstable due to uncontrollable factors.

[0017] 3) Because the locking mechanism uses an elastic snap-fit ​​to achieve locking, it is easy to operate and very convenient to fold later. Attached Figure Description

Detailed Implementation

[0023] like Figure 1 As shown, a foldable steel frame cable support includes a cable rack 1, a folding mechanism 2, and a cable tray 3.

[0024] The cable rack 1 is made of welded circular steel pipes, and the outer sections of the steel pipes are painted with black and yellow reflective warning paint. The cable rack 1 is divided into a left sub-rack 1.1 and a right sub-rack 1.2. The upper ends of the left sub-rack 1.1 and the right sub-rack 1.2 are connected by cable trays 3, and the lower ends of the left sub-rack 1.1 and the right sub-rack 1.2 are connected by a folding mechanism 2.

[0025] The folding mechanism 2 includes a first connecting rod 2.1 and a second connecting rod 2.2. Sleeves 2.3 are welded to the outer ends of both the first connecting rod 2.1 and the second connecting rod 2.2. The sleeves 2.3 are connected to the crossbeams on the left sub-frame 1.1 or the right sub-frame 1.2. The inner ends of the first connecting rod 2.1 and the second connecting rod 2.2 are hinged together by hinges 2.4.

[0026] The cable tray 3 includes an inner connecting wire 3.1, which is made of steel strand. The steel strand consists of multiple strands, and both ends are fixed to the left sub-frame 1.1 and the right sub-frame 1.2 by U-shaped clamps. The diameter of the steel strand is 6mm. The outer layer of the steel strand is covered by a sleeve 3.2, which is a high-temperature resistant glass fiber tube.

[0027] like Figure 2 As shown, preferably, the lower ends of the first link 2.1 and the second link 2.2 are locked by the locking mechanism 2.5, so that the first link 2.1 and the second link 2.2 maintain a straight state during operation, making the state of the left subframe 1.1 and the right subframe 1.2 more stable.

[0028] like Figure 3 As shown, the locking mechanism 2.5 includes a connecting rod 2.5.1. One end of the connecting rod 2.5.1 is fixed to the first connecting rod 2.1, and the other end of the connecting rod 2.5.1 is fixed to a clamping seat 2.5.2. The clamping seat 2.5.2 has an insertion hole 2.5.3. The two ends of the side wall of the insertion hole 2.5.3 have slots facing each other. The slots are connected to the clamping head 2.5.5 by a spring 2.5.4. The clamping head 2.5.5 extends partially under the action of the spring 2.5.4. A locking block 2.5.6 is inserted into the insertion hole 2.5.3 of the clamping seat 2.5.2. The outer end of the locking block 2.5.6 is fixedly connected to the guide rod 2.5.7. A compression spring 2.5.8 is sleeved on the guide rod 2.5.7. The other end of the guide rod 2.5.7 passes through a hole on the ear plate 2.5.9 and is threadedly connected to the limiting nut 2.5.10. Ear plate 2.5.9 is fixed to the second connecting rod 2.2.

[0029] When locking block 2.5.6 moves to the left into locking seat 2.5.2, the beveled front end of locking block 2.5.6 contacts locking head 2.5.5 and pushes locking head 2.5.5 into the slot. When the groove of locking block 2.5.6 is aligned with locking head 2.5.5, locking head 2.5.5 engages with locking block 2.5.6 to achieve locking. Conversely, when locking block 2.5.6 moves to the right away from locking seat 2.5.2, locking block 2.5.6 pushes locking head 2.5.5 again, pushing locking head 2.5.5 into the slot until locking block 2.5.6 disengages from locking seat 2.5.2.

[0030] Additionally, a magnet is fixed to the lower end of the second connecting rod 2.2 and to the left of the ear plate 2.5.9. After the locking block 2.5.6 disengages from the clamping seat 2.5.2, it can be magnetically attracted and fixed to the magnet. In this way, when the left sub-frame 1.1 and right sub-frame 1.2 are folded together without the need to install cables, the locking block 2.5.6 can always remain in the disengaged state, facilitating operation.

[0031] Working principle and process: According to the on-site cable laying plan, open the left sub-frame 1.1 and right sub-frame 1.2 of the cable support. After straightening the first connecting rod 2.1 and the second connecting rod 2.2, push the guide rod 2.5.7 to the left. The locking block 2.5.6 is inserted into the clamping seat 2.5.2 and tightened by the clamp head 2.5.5. This keeps the first connecting rod 2.1 and the second connecting rod 2.2 in a horizontal and stable state. Arrange multiple cable supports appropriately on the construction site. Then, place the cables in the cable trays 3 of the multiple cable supports to complete the installation. After use, pull the guide rod 2.5.7 to the right to disengage the locking block 2.5.6 from the locking seat 2.5.2. The locking block 2.5.6 is then fixed to the magnet at the lower end of the second connecting rod 2.2, allowing the hinge 2.4 to rotate. This applies downward force to the hinge 2.4 and simultaneously closes the left subframe 1.1 and the right subframe 1.2, thus achieving folding of the left subframe 1.1 and the right subframe 1.2 and saving space.
