Description

Technical Field

[0001] This invention relates to the field of cable support technology, and in particular to a foldable cable support and its method of use. Background Technology

[0002] Cable supports are typically installed on the side walls of cable channels to support cables. They are generally classified into trough type, tray type, ladder type, and mesh type structures, and consist of supports, brackets, and installation accessories. Common cable supports are usually formed by hot-dip plastic molding, metal casting, or metal welding, which results in high overall costs and they are usually not foldable. This leads to the following problems with cable supports: (1) They are prone to collisions during transportation and handling, which can cause local damage, affecting their strength or rendering them unusable; (2) The inability to fold them results in a large space occupation during transportation; (3) They cannot be folded after installation, and it is impossible to select the appropriate number of cable supports according to the cable support requirements after installation. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a foldable cable bracket and its usage method. The cable bracket is in a folded state during transportation and handling, which occupies little space and can effectively prevent collisions from affecting performance. After installation, the usage state or folded state can be selected according to actual needs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A foldable cable bracket includes a mounting base and a cable support component disposed within the mounting base, wherein both the mounting base and the cable support component are made of square tubing of a predetermined length. The mounting base has mounting holes at both ends of its bottom surface, and oblique cuts at both ends of its outer side surface corresponding to the mounting holes. The mounting base also has storage holes on its outer side surface. The lower end of the cable support is rotatably connected to the mounting base. The cable support has a first state in which it is housed in the mounting base and a second state in which it rotates outward from the housing hole to abut against the lower end of the housing. In the second state, the cable support is perpendicular to the mounting base.

[0005] Preferably, the mounting base has a support portion located at the lower end of the receiving hole. The support portion is formed by bending inward from the outer side of the mounting base and has an oblong hole. In the second state, the lower outer side of the cable support member has a threaded hole corresponding to the oblong hole. The long slot is connected to the oblong hole by a first bolt. After the cable support member is rotated to the second state, it is connected to the cable support member through the support portion and the first bolt, further increasing the support strength and maintaining the stability of the vertical state.

[0006] Preferably, the lower end of the cable support is provided with coaxially distributed inner connecting holes on both sides, and the mounting base is provided with coaxially distributed outer connecting holes on both sides. The outer connecting holes and the inner connecting holes are rotatably connected by a rotating shaft. The diameter of the outer connecting hole is larger than that of the inner connecting hole. The rotating shaft includes a rotating shaft body that is clearance-fitted with the inner connecting hole, a column at one end of the rotating shaft body that is clearance-fitted with the outer connecting hole, and a limiting protrusion at the outer end of the column. The other end of the rotating shaft is provided with a locking sleeve, which is threadedly connected to the rotating shaft body. The outer diameter of the locking sleeve is equal to the outer diameter of the column, and the end face of the locking sleeve abuts against the side of the cable support. Through the specific design of the outer connecting hole, the inner connecting hole, and the rotating shaft, the cable support is axially limited to prevent lateral swaying. This allows the cable support to stably switch between the first and second states without interfering with the edge of the storage device, improving stability and convenience of use.

[0007] Preferably, the end of the limiting protrusion ring and the outer end of the locking sleeve are both provided with cross grooves for positioning the screwdriver.

[0008] Preferably, the lower end of the outer side of the mounting base has a through hole, and a proximity switch is provided inside the mounting base corresponding to the through hole. The outer side of the cable support extends vertically outward to form a lug. In the second state, the lug is close to the outer side of the mounting base and closes the through hole, and the proximity switch detects the signal from the lug. Prolonged use, oxidation caused by moisture, and corrosion can damage the cable bracket. The most vulnerable part of the cable bracket is the pivot. When the pivot is damaged, the cable support separates from the mounting base, and the proximity switch loses its detection signal. This allows for quick identification of which cable bracket is damaged, facilitating rapid repair by inspection personnel.

[0009] Preferably, the cable support includes an extension member made of a square tube of a predetermined length, which is inserted into the cable support to form a sliding connection. The outer surface of the cable support has elongated slots distributed along its length, and a stud extending into the slot is fixed to the side of the extension member, with a locking nut on the stud. In cable channels containing numerous cables, the extension member further extends the length of the cable support to accommodate the increased cable support requirements.

[0010] Preferably, the outer end of the extension has a beveled cut, and the extension bends inward on the surface opposite to the beveled cut to form a lug. The lug facilitates the use of fingers to pull the extension out of the cable support.

[0011] Preferably, the cable support is provided with a U-shaped clamp for cable positioning, with both ends of the U-shaped clamp bent and extended to form arc-shaped positioning portions. In the second state, the upper side of the cable support is provided with two positioning slots corresponding to the two ends of the U-shaped clamp, and each positioning slot has an unlocking slot on one side. The maximum distance between the two unlocking slots is greater than the maximum distance between the positioning slots. A transition groove is provided between the inner ends of the positioning slots and the unlocking slots. When the cable needs to be positioned by the U-shaped clamp, the two ends of the U-shaped clamp are aligned with the positioning slots and pressed down. The arc-shaped positioning portions at both ends of the U-shaped clamp are deformed under pressure and inserted into the positioning slots. When the U-shaped clamp needs to be removed, it is pushed into the unlocking slot and then removed. For some large cables, U-shaped clamps are needed for further positioning of the cable. The installation and removal of the U-shaped clamp in this structure are very convenient.

[0012] A method of using a foldable cable bracket includes the following steps: s1. The initial state is the first state. In the first state, the extension extends slightly from the upper end of the cable support so that the cable support cannot be rotated to the second state. The locking nut is in the locked state, and the first bolt is only connected to the threaded hole. s2. The following steps are included when using it: s2-1, First fix the mounting holes at both ends of the mounting base to the side wall of the cable channel; s2-2, Remove the first bolt and loosen the lock nut to allow the extension to retract into the cable support; s2-3, rotate the cable support to the second state, and tighten the long slot and threaded hole with the first bolt; s2-4, Select the appropriate position after pulling the extension piece out of the cable support piece according to actual needs, and then tighten the locking nut; S2-5, after supporting the cable, insert the U-shaped hoop into the limiting slot to limit the cable.

[0013] Preferably, after the first bolt connects and tightens the long slot and threaded hole, the lug is brought close to the proximity switch, and the proximity switch is connected to the detection system in the cable channel. The proximity switch transmits the detection signal to the central control console. When the cable support fails or is damaged, the proximity switch loses the detection signal, and the detection system transmits the signal of the cable support to the central control console and issues a preset warning.

[0014] Therefore, the present invention has the following beneficial effects: (1) It is small in size when folded, making transportation and handling more convenient, and at the same time, it is not easy to damage the cable support; (2) The main structure is made of square tubes, which are simple to obtain, have low manufacturing cost and high structural strength; (3) After installation, the usage state or folded state can be selected according to actual needs, and the length of the extension section can be adjusted according to the number of cables to meet the needs.

Both the mounting base 1 and the cable support 2 are made of square tubes of a predetermined length. The cross-section of the square tube is rectangular. The side length of the square tube used to make the mounting base is greater than the side length of the square tube used to make the cable support 2, so that the mounting base can completely accommodate the cable support. The bottom surface of the mounting base 1 has mounting holes 100 at both ends, and the outer side of the mounting base has oblique cuts 101 at both ends corresponding to the mounting holes. The outer side of the mounting base also has storage holes 102. The lower end of the cable support 2 is rotatably connected to the mounting base 1. The cable support 2 has a first state in which it is housed in the mounting base 1 and a second state in which it rotates outward from the housing hole 102 to abut against the lower end of the housing control. In the second state, the cable support 2 is perpendicular to the mounting base 1.

[0030] like Figure 3 and Figure 4 As shown, a support part 3 is provided at the lower end of the storage hole inside the mounting base 1. The support part 3 is formed by bending inward from the outer side of the mounting base. The support part is perpendicular to the bottom surface of the mounting base. The support part 3 is provided with a waist-shaped hole 30. In the second state, the lower side of the cable support 2 is provided with a threaded hole 20 corresponding to the waist-shaped hole. The waist-shaped hole is connected to the threaded hole 20 by a first bolt 4.

[0031] like Figure 3 and Figure 9 As shown, a through hole 103 is provided at the lower end of the outer side of the mounting base 1, and a proximity switch 5 is provided in the mounting base 1 at the position corresponding to the through hole. The outer side of the cable support 2 is bent vertically outward to form a lug 21. In the second state, the lug 21 is close to the outer side of the mounting base and closes the through hole, and the proximity switch detects the signal of the lug.

[0032] like Figure 9 and Figure 10As shown, the lower end of the cable support 2 has coaxially distributed inner connecting holes 22 on both sides, and the mounting base 1 has coaxially distributed outer connecting holes 104 on both sides. The outer connecting holes and the inner connecting holes are rotatably connected by a rotating shaft 6. The diameter of the outer connecting hole is larger than that of the inner connecting hole. The rotating shaft 6 includes a rotating shaft body 60 that is clearance-fitted with the inner connecting hole, a column 61 that is clearance-fitted with the outer connecting hole at one end of the rotating shaft body, and a limiting protrusion ring 62 at the outer end of the column. The other end of the rotating shaft is provided with a locking sleeve 63, which is threadedly connected to the rotating shaft body. The outer diameter of the locking sleeve is equal to the outer diameter of the column, and the end face of the locking sleeve abuts against the side of the cable support. The end of the limiting protrusion ring 62 and the outer end of the locking sleeve 63 are both provided with cross grooves 620 for screwdriver positioning.

[0033] The cable support 2 has an extension 7 inside, which is made of a square tube of a predetermined length. The extension 7 is inserted into the cable support 2 to form a sliding connection. The outer side of the cable support 2 (the lower side in the second state) has elongated slots 23 distributed along the length of the cable support. A stud 70 extending into the elongated slot is fixed to the side of the extension 7, and a locking nut 71 is provided on the stud. The outer end of the extension 7 has a beveled cut, and the extension bends inward on the surface opposite to the beveled cut to form a lug 72.

[0034] In some embodiments, to further increase the stability of cable positioning, the following schemes are adopted: such as Figure 5 and Figure 6 As shown, the cable support 2 is provided with a U-shaped hoop 8 for cable positioning. The two ends of the U-shaped hoop 8 are bent and extended to form arc-shaped positioning portions 80. In the second state, the upper side of the cable support 2 is provided with two positioning slots 200 corresponding to the two ends of the U-shaped hoop. Each positioning slot is provided with an unlocking slot 201 on one side. The maximum distance between the two unlocking slots is greater than the maximum distance between the positioning slots. A transition groove 202 is provided between the inner ends of the positioning slots and the unlocking slots. When the cable needs to be positioned by the U-shaped hoop, the two ends of the U-shaped hoop 8 are aligned with the positioning slots 200 and pressed down. The arc-shaped positioning portions 80 at both ends of the U-shaped hoop 8 are deformed by the pressure and inserted into the positioning slots. When it is necessary to remove the U-shaped hoop, the U-shaped hoop is pushed into the unlocking slots and then removed.
