DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] like Figure 1 A bundled cable pressing device shown includes a pressing device and a pressing base. The pressing device helps the bundled cables to apply downward pressure to fix them so that several lines at the bottom of the bundled cables are semicircular, while the pressing base tightens several lines at the top of the bundled cables from both sides to realize a circular mold and tightens and forms them.

[0016] The clamping base includes a base 1, a set of opposite sides of the base 1 are fixed baffles 2, the center of the base 1 is an arc-shaped strip groove 3, the fixed baffle 2 is parallel to the strip groove 3, two slidable clamping seats 4 are provided on the base 1, and the opposite sides of the two clamping seats 4 have an arc edge 5 facing the strip groove 3, the length of the clamping seat 4 is the same as the length of the strip groove 3, and the other side of the clamping seat 4 is provided with a telescopic rod 6 near the two sides, the telescopic rod 6 passes through the fixed baffle 2, and a transverse spring 7 is provided between the end of the telescopic rod 6 outside the fixed baffle 2 and the fixed baffle 2, and the area between the two telescopic rods 6 on the clamping seat 4 is an inclined surface, and a circular hole is formed when the two clamping seats 4 move to the position above the strip groove 3;

[0017] The pressing device includes a pressing block 8, which is driven by an external power to move up and down. A hole is opened in the center of the pressing block 8, and the hole opening faces the strip groove 3. A pressing rod 9 that moves along the hole is arranged in the hole. A longitudinal spring 10 is arranged between the top of the pressing rod 9 and the top of the hole. The bottom of the pressing rod 9 is a strip plate 11, which is parallel to the strip groove 3. A circular hole plate 12 is respectively arranged at both ends of the strip plate 11. The two circular hole plates 12 are respectively located at the front and rear positions of the base 1, and the bundled cables pass through the two circular hole plates 12; pressing wedge blocks 13 are arranged on both sides of the pressing block 8, and the inclined surface of the pressing wedge block 13 is parallel to the inclined surface of the clamping seat 4. A notch 14 is opened at the position of the base 1 directly below the pressing wedge block 13. The pressing wedge block 13 drives the clamping seat 4 to move toward the strip groove 3 through the inclined surface contacting the inclined surface of the clamping seat 4, and the pressing wedge block 13 can be inserted into the notch 14 of the base 1.

[0018] When in use, the multi-strand circuit is passed through the two circular hole plates 12 in turn for fixation, and the lower pressing block 8 moves downward, driving the lower pressing rod 9 to move downward as well. First, the multi-strand circuit between the two circular hole plates 12 reaches the strip groove 3, and at this time, the lower pressing block 8 continues to move downward, compressing the longitudinal spring 10, giving the multi-strand circuit a certain downward pressure in the strip groove 3, so that the lower circuit of the multi-strand circuit automatically undergoes a lower molding change according to the shape of the strip groove 3, and the lower pressing block 8 continues to move downward, so that the inclined surface of the lower pressing wedge block 13 of the lower pressing block 8 contacts the inclined surface of the clamping seat 4, driving the two clamping seats 4 to move toward the multi-strand circuit, and using its arc edge 5 to squeeze the multi-strand circuit from both sides, so that the upper circuit of the multi-strand circuit automatically undergoes an upper molding change according to the shape of the arc edge 5 on both sides, thereby achieving rounding and clamping.

[0019] After the rounding and clamping are completed, the lower pressing block 8 moves upward and gradually reduces the pressure. At this time, the inclined surface of the lower pressing wedge block 13 of the lower pressing block 8 is separated from the inclined surface of the clamping seat 4, and the clamping seat 4 is reset under the action of the transverse spring 7. The operator can continue to pull the multi-strand line and lead out the clamped part, so that the un-compressed multi-strand line enters between the two circular hole plates 12 and waits for the next clamping action.

[0020] In order to improve the pressing effect during the pressing process, a rotating sleeve 15 can be limitedly provided in the circular hole of the circular hole plate 12. The inner wall of the rotating sleeve 15 is a frosted surface with high friction, and the outer side of the rotating sleeve 15 is provided with a shifting block. During the pressing process, the rotating sleeve 15 can be manually rotated to adjust the tightness of the multi-strand line between the two circular hole plates 12, and the multi-strand line is continuously rubbed apart to achieve a better pressing effect. After one pressing, the bundled cables can also be rotated as a whole, the pressing part can be replaced, and a second pressing can be performed to improve the pressing effect.

[0021] It should be noted that the distance between the circular hole plate 12 and the strip groove 3 is smaller than the distance between the inclined surface of the pressing wedge block 13 and the inclined surface of the pressing seat 4, so as to ensure that the multi-strand line is first pressed at the bottom and then at the side.

[0022] The width of the inclined surface of the pressing wedge block 13 is greater than the width of the inclined surface of the pressing seat 4, ensuring that the pressing wedge block 13 has sufficient driving length to act on the pressing seat 4 as the pressing block 8 moves downward, and can cope with the compression of cables of various diameters.

[0023] There are also requirements for the selection of the clamping length. The length of the strip groove 3 is 3-10 times the inner diameter of the circular hole formed by the two clamping seats 4 and the strip groove 3. If the length of the cable clamped at one time is too long, there will be problems of line entanglement and superposition. The cable length is controlled within this range, which is convenient for viewing and adjustment.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
