Description

Technical Field

[0001] The present invention relates to the technical field of power cables, and in particular to a flexible cable connecting device. Background Art

[0002] In modern industrial production and daily life, power transmission and signal transmission play a vital role. Flexible cables are the first choice for power transmission materials and signal transmission carriers in drag chain motion systems. They are widely used, including but not limited to power supply for fire fighting equipment and fire elevators in various buildings, power supply for equipment and lighting systems in important buildings or buildings with dense populations, places with high ambient temperature (such as steel mills, smelters, glass factories, etc.), important flammable and explosive occasions (such as power supply for petrochemical and coal mining equipment), places that require special cleanliness (such as hospitals, food factories, etc.), and power supply for important equipment in power plants and nuclear power plants. At present, when two flexible cables are connected at the end, they are usually fixed by threaded pipes. This fixing method is not only not stable enough, but also when connected, the two flexible cables are not on the same horizontal plane, which will cause the connection line of the two cables to be separated, resulting in poor contact.

[0003] In the prior art, a Chinese patent with patent number: CN202222263690.2 discloses a flexible cable connection device with a sealing structure, comprising two housings, and two sides of the two housings are rotatably connected to two threaded rotating rods. The advantage of the device is that the connection of the cable is placed on a fixing ring, the two housings are covered together, and then two threaded fixing rings are used to install on a fixing block, and then the two housings are connected together, and sealing rings are installed on the two second through holes, and the sealing rings seal the connection between the cable and the housing, and then the two threaded rotating rods are rotated, and the two threaded rotating rods will move with the limit plates, and the two limit plates are a group, and the threaded rotating rods will move with the two limit plates toward each other, and the fixing ring is installed on the limit plate through the connecting plate, and then the fixing ring will also move toward each other with the limit plate, and the two limit plates will clamp the cable in the middle to clamp the cable, and the two fixing rings are docked together to limit and fix the cable connection.

[0004] Although the above device has many advantages, it still has the following shortcomings during actual use: the threaded rotating rod is prone to unnecessary rotation due to external factors such as vibration and friction, causing the two limit plates to move toward both sides respectively, thereby causing the two fixing rings to be unable to tightly fix the flexible cable, making the connection between the two flexible cables at risk of detachment under the action of external force, thereby reducing the stability of the flexible cable fixation.

DETAILED DESCRIPTION

[0027] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0028] Now refer to Figure 1-7 , combined with a specific embodiment, it is explained as follows: a flexible cable connection device described in the present invention comprises an upper sealing seat 1 and a lower sealing seat 2 located below the upper sealing seat 1, the upper sealing seat 1 is detachably connected to the lower sealing seat 2 by a fixing bolt 5, thereby forming a complete sealing seat, and the sealing seat is used to seal the connection between the two flexible cables 42; two fixing mechanisms 7 are symmetrically arranged on both sides of the interior of the upper sealing seat 1, and the fixing mechanism 7 is used to fix the flexible cable 42; a support plate 16 corresponding to the fixing mechanism 7 is arranged on the top surface of the upper sealing seat 1, and a support seat 17 is arranged on the support plate 16; a first limiting mechanism 18 is arranged inside the support seat 17, the first limiting mechanism 18 is connected to the fixing mechanism 7, and the first limiting mechanism 18 can limit the fixing mechanism 7.

[0029] Specifically, the fixing mechanism 7 includes an upper fixing cover 8 and a lower fixing cover 9 located below the upper fixing cover 8, the upper fixing cover 8 is connected to the lower fixing cover 9 to form a complete fixing cover, and the fixing cover can cover the flexible cable 42; one side of the upper fixing cover 8 and the lower fixing cover 9 are connected to a fixing block 10, and the inside of the two fixing blocks 10 are commonly screwed with a threaded rod 11; the threaded rod 11 passes through the two fixing blocks 10, the top of the threaded rod 11 passes through the top surface of the support seat 17 and is connected to the first limiting mechanism 18 inside the support seat 17, and the bottom end of the threaded rod 11 is rotatably connected to a connecting plate 12; connecting rods 13 are respectively arranged on both sides of the threaded rod 11, and the connecting rod 13 movably passes through the two fixing blocks 10, the top of the connecting rod 13 is connected to the upper sealing seat 1 through a connecting block 14 and a connecting bolt 15, and the bottom end of the connecting rod 13 is connected to the connecting plate 12. Since the threaded rod 11 is screwed together with the two fixed blocks 10, when the threaded rod 11 is rotated, the two fixed blocks 10 will move relative to each other or move away from each other at the same time, and the movement of the fixed blocks 10 will also move the upper fixed cover 8 and the lower fixed cover 9 together, that is, the upper fixed cover 8 and the lower fixed cover 9 are closed or opened.

[0030] Specifically, the first limiting mechanism 18 includes a ratchet 19 and a ratchet 20. The ratchet 19 is installed on the threaded rod 11. One end of the ratchet 20 is meshed with the ratchet 19, and the other end of the ratchet 20 is rotatably connected to a positioning rod 21 fixed on the support plate 16; a positioning plate 24 located on one side of the ratchet 20 is provided on the support plate 16, and a first spring 23 is provided between the ratchet 20 and the positioning plate 24, and the two ends of the first spring 23 respectively abut against the ratchet 20 and the positioning plate 24; a first stretching member 25 is provided at one end of the ratchet 20 meshing with the ratchet 19, and the first stretching member 25 extends to the outside of the support seat 17. When the threaded rod 11 is rotated clockwise, the ratchet 19 can rotate normally, and the upper fixed cover 8 and the lower fixed cover 9 can be closed; at the same time, because the ratchet 20 is stuck in the ratchet 19, the ratchet 19 cannot rotate, thereby preventing the threaded rod 11 from rotating counterclockwise due to external factors, that is, preventing the upper fixed cover 8 and the lower fixed cover 9 from opening; if the threaded rod 11 needs to be rotated counterclockwise, the ratchet 20 can be pulled by the first stretching member 25, so that the ratchet 20 is separated from the ratchet 19, and then the threaded rod 11 can be rotated counterclockwise, that is, the upper fixed cover 8 and the lower fixed cover 9 are opened.

[0031] Specifically, the first tensioning member 25 includes a first pull rope 26 , one end of which is connected to a pull block 27 , which is fixed to the ratchet 20 , and the other end of the first pull rope 26 is connected to a first pull rod 28 , which passes through and is screwed to the support seat 17 .

[0032] Specifically, a second limiting mechanism 29 capable of limiting the fixing mechanism 7 is arranged above the first limiting mechanism 18, and the second limiting mechanism 29 includes a gear 30 and a mounting plate 31, the gear 30 is mounted on the threaded rod 11, and the mounting plate 31 is fixed on the support plate 16 and is located on one side of the gear 30; a mounting seat 32 is arranged on the side surface of the mounting plate 31 facing the gear 30, and a slide plate 33 is slidably arranged inside the mounting seat 32; a sliding rod 34 is connected to the side surface of the slide plate 33 facing the gear 30, and the sliding rod 34 is connected to a mounting block 35 capable of meshing with the gear 30 after passing through the mounting seat 32; two second springs 36 are symmetrically arranged between the side surface of the slide plate 33 facing away from the gear 30 and the mounting plate 31, and the two ends of the second spring 36 respectively abut against the mounting plate 31 and the slide plate 33; a second stretching member 37 is arranged between the two second springs 36 on the side surface of the slide plate 33 facing away from the gear 30, and the second stretching member 37 extends to the outside of the support seat 17. When the gear 30 and the mounting plate 31 are in meshing state, the threaded rod 11 can neither rotate clockwise nor counterclockwise, which plays the role of secondary limiting the threaded rod 11. If the threaded rod 11 needs to be rotated, the slide plate 33, the slide bar 34, and the mounting block 35 are pulled forward by the second tensioning member 37, so that the mounting block 35 is separated from the gear 30, and the threaded rod 11 can be rotated in this state.

[0033] Specifically, the second tensioning member 37 includes a second pull rope 38 movably passing through the mounting plate 31 , one end of the second pull rope 38 is connected to the slide plate 33 , and the other end of the second pull rope 38 is connected to a second pull rod 39 , which passes through and is screwed to the support seat 17 .

[0034] The use principle of the present invention is as follows: First, two flexible cables 42 are respectively passed through a fixing mechanism 7, that is, the flexible cables 42 are between the upper fixing cover 8 and the lower fixing cover 9, and then the two flexible cables 42 are connected and insulation measures are taken. After the above preparations are completed, the staff first separates the gear 30 from the mounting block 35 through the second stretching member 37. At this time, the threaded rod 11 can be rotated clockwise. Under the cooperation of the fixing block 10, the threaded rod 11 and the connecting rod 13, the upper fixing cover 8 and the lower fixing cover 9 are closed, thereby firmly fixing the flexible cable 42, effectively avoiding the problem of external tension breaking the cable connection. At the same time, under the action of the first limiting mechanism 18, that is, the ratchet 19 and the ratchet 20, the threaded rod 11 can be prevented from rotating counterclockwise due to external factors, thereby avoiding the problem of the upper fixing cover 8 and the lower fixing cover 9 causing the pressure drop of the cable; when the upper fixing cover 8 and the lower fixing cover 9 need to be opened, the ratchet 19 and the ratchet 20 can be separated by the first stretching member 25. After the cable fixing work is completed, the second tensioning member 37 is released, and under the action of the second spring 36, the mounting block 35 is reset and re-engaged with the gear 30, and the threaded rod 11 cannot rotate at this time, further avoiding the problem of pressure drop on the cable caused by the upper fixing cover 8 and the lower fixing cover 9. After the above work is completed, the upper sealing seat 1 and the lower sealing seat 2 can be installed together.

[0035] In one embodiment, a positioning block 22 is provided on the ratchet 20, and the end of the first spring 23 is sleeved on the positioning block 22. The above structure not only realizes the detachable connection between the ratchet 20 and the first spring 23, but also ensures the connection stability between the two.

[0036] In one embodiment, a mounting sleeve 40 for connecting the mounting plate 31 is provided on the support plate 16, the bottom end of the mounting plate 31 is disposed inside the mounting sleeve 40, and the mounting sleeve 40 and the mounting plate 31 are connected by a mounting bolt 41. The above structure realizes a detachable connection between the support plate 16 and the mounting plate 31, so as to facilitate assembly.

[0037] In one embodiment, both ends of the upper sealing seat 1 and the lower sealing seat 2 are provided with sealing rings 3, and the interiors of the upper and lower sealing rings 3 are screwed with sealing covers 4, and the inner side of the sealing covers 4 is provided with sealing sleeves 6, which can be sleeved on the flexible cables 42. The two flexible cables 42 are respectively sleeved with a sealing cover 4, and the sealing cover 4 can improve the sealing effect of the device on the cables; at the same time, the material of the sealing sleeve 6 is preferably rubber, and the inner diameter of the sealing cover 4 is slightly smaller than the outer diameter of the cable, so that it can fit the cable tightly, further improving the sealing effect of the device.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
