Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a cable tensile strength detection device used for cable production. Background Art

[0002] Cable is a device for transmitting electric energy or signals. It is usually a rope-like cable made of several or several groups of wires (at least two wires in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating coating. Cables have the characteristics of being powered inside and insulated outside. Wires and cables need to be tested for tensile strength during production and processing.

[0003] A Chinese patent with publication number CN219676168U discloses a coaxial cable network performance detection device. By placing both sides of the cable on locking frames at both ends and fixing them with locking parts, driving the motor to rotate the bidirectional screw rod, the two sets of moving blocks can be controlled to drive the upper locking frame to move and stretch the cable, which can meet the needs of fixing cables of different lengths. At the same time, the tensile strength of the cable can be tested by a dynamometer. The cable performance can be quickly tested by a mobile detection mechanism, making the device more applicable and the detection efficiency higher.

[0004] However, in the above scheme, the cable is compressed by a screw and a pressure plate, and a protrusion is set at the lower end of the pressure plate for compression. The cable may slide or move during the clamping process, and the clamping is not stable enough, which in turn affects the test effect. Only cables of a single shape can be clamped, and the clamping has limitations.

[0005] Therefore, it is necessary to invent a cable tensile strength testing device for cable production. Utility Model Content

[0033] Working principle: When using this solution, first, a suitable clamping tool can be selected according to the shape of the cable to be tested. If the tensile strength of the cable itself needs to be tested, the cable can be passed through the gap between the pressure plate 174 and the rubber plate 176, and one end of the cable can be placed between the clamping rings 26 on both sides. Then, the double-headed threaded rod 21 is rotated, thereby driving the two long plates 24 to move toward each other, and then driving the clamping rings 26 on both sides to move toward each other to clamp one end of the cable. At the same time, the spring telescopic rod 25 will be compressed to stably clamp one end of the cable. The clamping device on the rectangular block 11 can be used to clamp the other end of the cable. Then, the threaded column 15 is rotated, thereby driving the slider 16 and the rectangular block 17 to move away from each other. The rectangular block 11 moves in the direction. When the rectangular block 2 17 slides and adjusts to just straighten the cable, stop rotating the threaded column 15, and record the reading of one end of the rectangular block 2 17 on the scale 13 at this time. Then continue to start the threaded column 15. When the rectangular block 2 17 continues to slide in the chute 2 14, it will continue to pull the entire cable. When the critical point of the entire cable is damaged is reached, record the reading of the rectangular block 2 17 on the scale 13 at this time. The sliding distance of the rectangular block 2 17 is the length of the entire cable stretch, that is, the distance that one end of the rectangular block 2 17 moves on the scale 13. Subtract the previous reading from the latter reading to get the limit length of the entire cable stretch. The detection is simple and the reading is convenient.

[0034] When the tensile performance of the insulating sheath needs to be tested, one end of the insulating sheath can be placed on the top of the rubber plate 176, and the double-headed threaded rod 21 is rotated to drive the gear 22 to rotate, and then the rack 171 is driven to move downward, and then the connecting plate 172 and the pressing plate 174 are driven to move downward, and then one end of the insulating sheath is pressed tightly by the spring telescopic rod 173, and the other end of the insulating sheath can be pressed by the clamping device on the rectangular block 11. The same method can be used to detect the maximum length of the insulating sheath;

[0035] When the cable itself is fixed, the clamping rings 26 on both sides move towards each other to clamp one end of the cable, and at the same time, the connecting plate 172 and the pressing plate 174 are moved downward to press the end of the cable itself and further fix the cable itself.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
