[0002] A vertical burning tester for wire and cable is a device specially designed to evaluate the combustion characteristics and flame retardant ability of wire and cable insulation materials under flame exposure. This tester is usually used in the quality control process of wire and cable products that meet specific safety standards, such as UL94, GB / T 18380, etc.; the working principle of this device is to vertically fix the wire and cable sample in the tester, and set an ignition burner on one side of the sample to apply a flame of a certain height. After the flame burns continuously for a certain time, it is removed, and then the combustion behavior of the wire and cable is observed and recorded; however, the existing vertical burning tester has too simple a fixing method for the wire and cable sample. Some are usually just inserted on the internal fixing table. This method not only easily causes the wire and cable sample to fall during combustion, but also cannot adjust different angles to observe the combustion situation of the wire and cable sample. At the same time, when fixing the wire and cable sample, it cannot be straightened, and the use effect of fixing the wire and cable needs to be improved. Therefore, it is necessary to propose a vertical burning tester for wire and cable. Content of the Utility Model

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A vertical burning tester for wire and cable includes a detection box body and an ignition burner vertically installed on the inner side wall of the detection box body. An installation table is rotatably installed inside the detection box body, and the installation table is located on one side of the ignition burner. A regulating clamping assembly for clamping the wire and cable is arranged on the side of the installation table facing the ignition burner. The regulating clamping assembly includes two relatively arranged clamping blocks, and the two ends of the wire and cable are fastened by the two clamping blocks. The two clamping blocks are relatively slidably arranged on the installation table;

[0005] Insertion holes are vertically opened in the middle of the two clamping blocks, and observation through holes communicating with the middle of the insertion holes are longitudinally opened in the middle of the clamping blocks;

[0006] A wire pressing bolt is threadedly inserted through the right side of the clamping block, and the wire pressing bolt can be screwed into one side of the insertion hole.

[0007] Further improvements are as follows: A connecting rod is fixedly provided at the rear side of the clamping block, and a threaded sleeve is connected to the end of the connecting rod. An inward sliding groove is formed on the front side of the mounting table facing the ignition burner, and a driving screw rod is rotatably installed inside the sliding groove, and the threaded sleeves of the two clamping blocks are respectively thread-driven by the driving screw rod.

[0008] Further improvements are as follows: Transmission threads are oppositely arranged on the upper and lower sides of the driving screw rod, and the two driving screw rods are respectively thread-connected to the two threaded sleeves.

[0009] Further improvements are as follows: A rotating handwheel is provided on the upper side of the mounting table, and the rotating handwheel is installed at one end of the driving screw rod.

[0010] Further improvements are as follows: One side of the mounting table is rotatably installed on one side of the detection box body through a rotating shaft, and a rotating motor connected to the rotating shaft is installed on the outer side of the detection box body.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution for a wire and cable vertical combustion tester: including a detection box body 1 and an ignition burner 2 vertically installed on the inner side wall of the detection box body 1. A mounting table 3 is rotatably installed inside the detection box body 1. The mounting table 3 is located on one side of the ignition burner 2. On the side of the mounting table 3 facing the ignition burner 2, an adjusting clamping assembly for clamping the wire and cable is provided. After the mounting table 3 rotates, the wire and cable clamped by the clamping assembly can be rotated and adjusted, so as to adjust to the required observation angle. The adjusting clamping assembly includes two oppositely arranged clamping blocks 4, and the two ends of the wire and cable are fastened by the two clamping blocks 4. The two clamping blocks 4 are slidably arranged relative to each other on the mounting table 3. Therefore, the wire and cable of different lengths can be adapted to be clamped by sliding the two clamping blocks 4 in the relative or opposite directions, and the wire and cable can be pulled and tightened, better simulating the actual adaptation situation; in order to be able to clamp the wire and cable by the clamping block 4, wire insertion holes 41 are vertically opened in the middle of the two clamping blocks 4 for the wire and cable to be inserted. A wire top bolt 5 is threaded through the right side of the clamping block 4. During use, the wire top bolt 5 can be screwed into one side of the wire insertion hole 41 and directly clamp the wire and cable in the wire insertion hole 41. An observation through hole 42 longitudinally communicating with the middle of the wire insertion hole 41 is opened in the middle of the clamping block 4, which is mainly used to better observe whether the wire and cable is clamped in the wire insertion hole 41 to facilitate adjustment.

[0022] In order to enable the two clamping blocks 4 to slide synchronously in opposite or relative directions, a connecting rod 43 is fixedly installed at the rear side of the clamping block 4, and a threaded sleeve 44 is connected to the end of the connecting rod 43. A sliding groove 6 is inwardly formed on the front side of the mounting table 3 facing the ignition burner 2, and a transmission screw rod 7 is rotatably installed inside the sliding groove 6. The threaded sleeve 44 is slidably inserted into the sliding groove 6 and sleeved on the transmission screw rod 7. The threaded sleeves 44 of the two clamping blocks 4 are respectively threadedly driven by the transmission screw rod 7. The upper and lower sides of the transmission screw rod 7 are provided with opposite transmission threads 71, and the two transmission screw rods 7 are respectively threadedly connected to the two threaded sleeves 44. A rotating handwheel 8 is provided on the upper side of the mounting table 3, and the rotating handwheel 8 is installed at one end of the transmission screw rod 7. Therefore, after rotating the handwheel, the transmission screw rod 7 drives the two oppositely arranged threaded connections to rotate, and respectively threadedly drives the two threaded sleeves 44 to slide in opposite or relative directions along the sliding groove 6, so as to achieve the clamping and tensioning of electric wires and cables of different lengths.

[0023] Moreover, in order to enable the rotation of the clamped electric wire and cable, one side of the mounting table 3 is rotatably installed on one side of the detection box body 1 through a rotating shaft, and a rotating motor 31 connected to the rotating shaft is installed on the outer side of the detection box body 1. Therefore, the rotating motor 31 can directly drive the rotation of the mounting table 3, and then the electric wire and cable clamped by the two clamping blocks 4 on the mounting table 3 rotates.
