Description

Technical Field

[0001] This utility model relates to the technical field of fire resistance testing devices for electrical wires, and more specifically, to a flexible, environmentally friendly, fire-resistant electrical wire testing device. Background Technology

[0002] Flexible environmentally friendly fireproof wires (flexible fireproof cables) are environmentally friendly cables that use inorganic mineral insulation materials and have flexibility and excellent fire resistance.

[0003] Currently, during the production process of flexible environmentally friendly fire-resistant wires, testing equipment is needed to test the abrasion resistance of the fire-resistant wires. However, commonly used fire-resistant wire fire resistance testing equipment is not easy to quickly locate the fire-resistant wires during use, and the size range of the fixed fire-resistant wires is small. For example, a fire-resistant wire fire resistance testing device disclosed in publication number CN 221038902U includes a base, a spray gun, a fixing block, and a housing. The upper front part of the base is symmetrically provided with spray guns for burning the cable. The upper rear part of the base is provided with a fixing block. The upper part of the fixing block is provided with a housing. It also includes an upper cover, etc. The upper cover for protection is rotatably provided in the middle of the rear side of the housing.

[0004] As can be seen from the above-disclosed scheme, the fire resistance testing device for fire-resistant wires uses clips to fix the wires and also requires cutting the wires. Excessively long wires are inconvenient for testing, reducing the ease of positioning fire-resistant wires. Furthermore, fixing the fire-resistant wires with clips limits the range of outer diameter dimensions of the fire-resistant wires that the clips can clamp, thus narrowing the scope of application. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a flexible, environmentally friendly, fire-resistant wire testing device. This device, by setting two axially symmetrical positioning blocks at both ends of the testing chamber and a serpentine positioning groove on the positioning blocks, can quickly fix the fire-resistant wire in the testing chamber without cutting the fire-resistant wire, thus improving ease of use. Furthermore, the adjustment groove, slot, and retaining ring on the adjustment seat facilitate the replacement of different positioning blocks to position fire-resistant wires of different outer diameters, increasing the applicability.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A flexible, environmentally friendly, fire-resistant electrical wire testing device includes a fire resistance testing device body. The fire resistance testing device body includes a testing box, a handle fixedly connected to the outside of the testing box, a testing chamber on the surface of the testing box, grooves at both ends of the testing chamber, a spray gun body fixedly installed inside the testing chamber, and an axially symmetrical adjustment seat fixedly installed inside the testing chamber. Several positioning blocks are movably connected to the surface of the adjustment seat. A box cover is rotatably connected to the opening of the testing chamber, and a hinge is provided on the side of the box cover. This flexible, environmentally friendly, fire-resistant electrical wire testing device, by setting two axially symmetrical positioning blocks at both ends of the testing chamber and the serpentine positioning grooves set in the positioning blocks, can quickly fix the fire-resistant electrical wire in the testing chamber without cutting the fire-resistant electrical wire, improving the convenience of use. Furthermore, the adjustment groove, slot, and retaining ring set in the adjustment seat facilitate the replacement of different positioning blocks to position fire-resistant electrical wires of different outer diameters, increasing the applicability.

[0008] Furthermore, the surface of the adjusting seat has several adjusting grooves, and the adjusting grooves are distributed at equal intervals. The inner wall of the adjusting groove is slidably connected to the surface of the positioning block. The bottom of the adjusting groove has a locking groove. The adjusting groove facilitates the storage and positioning of the positioning block, and also facilitates the interchange of the positions of each positioning block.

[0009] Furthermore, the surface of the positioning block has a positioning groove, which is serpentine in shape. The positioning block is made of high-temperature resistant and flame-retardant nylon plastic. The serpentine positioning groove facilitates the axial position limitation of the fireproof wire, thereby making it suspended in a straight line inside the detection box.

[0010] Furthermore, a retaining ring is fixedly sleeved on the surface of the positioning block, and the surface of the retaining ring is movably connected to the inner wall of the retaining groove. The retaining ring is made of high-temperature resistant elastic rubber, and the retaining ring fixes the positioning block in the storage position in the adjustment groove by elastic force.

[0011] Furthermore, the side of the adjustment seat is fixedly connected to the inner wall of the testing chamber, and a weight-reducing groove is opened at the bottom of the adjustment seat. The adjustment seat is made of aluminum alloy material, and the weight-reducing groove can reduce the amount and weight of the adjustment seat.

[0012] Furthermore, a transparent plate is fixedly installed on the surface of the box cover. The transparent plate is made of high-temperature resistant transparent glass, which facilitates viewing the fire resistance test of the fireproof wire from the outside when the box cover is closed.

[0013] Furthermore, a compression strip is fixedly connected to the bottom of the lid. The compression strip is made of high-temperature resistant elastic memory foam. After the lid is closed, the compression strip can compress the fireproof wire and seal the groove.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can quickly fix the fireproof wire in the testing chamber by setting two axially symmetrical positioning blocks at both ends of the testing chamber and the serpentine positioning grooves set in the positioning blocks, without having to cut the fireproof wire, thus improving the convenience of use.

[0016] (2) This solution uses the adjustment slot, card slot and retaining ring set in the adjustment seat to facilitate the positioning of fireproof wires with different outer diameters by changing different positioning blocks, thus increasing the scope of application. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5A flexible, environmentally friendly fire-resistant wire testing device includes a fire resistance testing device body 1, which includes a testing box 2. The surface of the testing box 2 is provided with a buckle to lock the closed box cover 3. The device can be easily and conveniently moved by a handle 24. The handle 24 is fixedly connected to the outside of the testing box 2. A testing chamber 21 is provided on the surface of the testing box 2. Grooves 23 are formed at both ends of the testing chamber 21. The grooves 23 serve to prevent air leakage and avoid squeezing the fire-resistant wire when the box cover 3 is closed. Inside chamber 21, a spray gun body 22 is fixedly installed. The spray gun body 22 is used to burn the fireproof wire by spraying flames, thereby testing the fire resistance of the fireproof wire. The switch of the spray gun body 22 is located outside the test box 2. Inside the test chamber 21, an axially symmetrical adjustment seat 4 is fixedly installed. Several positioning blocks 5 are movably connected to the surface of the adjustment seat 4. The opening of the test chamber 21 is rotatably connected to the cover 3. The side of the cover 3 is provided with a hinge. The hinge is rotatably connected to the test box 2, thereby enabling the cover 3 to have a rotary switch function.

[0027] The surface of the adjusting seat 4 has several adjusting grooves 41, which are evenly spaced. The inner wall of the adjusting groove 41 is slidably connected to the surface of the positioning block 5. The bottom of the adjusting groove 41 has a slot 42. The adjusting groove 41 facilitates the storage and positioning of the positioning block 5 and makes it easy to change the position of each positioning block 5. The surface of the positioning block 5 has a positioning groove 51, which is serpentine in shape. The positioning block 5 is made of high temperature resistant and flame retardant nylon plastic. The serpentine positioning groove 51 facilitates the axial position limit of the fireproof wire, so that it is suspended in a straight line inside the detection box 2.

[0028] A retaining ring 52 is fixedly sleeved on the surface of the positioning block 5. The surface of the retaining ring 52 is movably connected to the inner wall of the groove 42. The retaining ring 52 is made of high-temperature resistant elastic rubber. The outer diameter of the retaining ring 52 is larger than the inner diameter of the groove 42. The retaining ring 52 fixes the positioning block 5 in the storage position in the adjustment groove 41 by elastic force. The side of the adjustment seat 4 is fixedly connected to the inner wall of the detection chamber 21. The bottom of the adjustment seat 4 has a weight reduction groove 43. The adjustment seat 4 is made of aluminum alloy material. The weight reduction groove 43 can reduce the amount and weight of the adjustment seat 4.

[0029] A transparent plate 31 is fixedly installed on the surface of the cover 3. The transparent plate 31 is made of high temperature resistant transparent glass. The transparent plate 31 makes it easy to close the cover 3 and observe the fire resistance test of the fireproof wire from the outside. A compression strip 32 is fixedly connected to the bottom of the cover 3. The compression strip 32 is made of high temperature resistant elastic memory foam. After the cover 3 is closed, the compression strip 32 can compress the fireproof wire and seal the groove 23.

[0030] When using this flexible, environmentally friendly fireproof wire testing equipment, first open the cover 3. Then, select the appropriate positioning block 5 for the positioning groove 51 according to the outer diameter of the fireproof wire, and move the positioning block 5 to the middle position of the adjusting seat 4 so that the positioning groove 51 of the positioning block 5 is connected to the groove 23. Then, wrap the fireproof wire around the positioning groove 51, making its surface contact the inner wall of the groove 23. Then, straighten the other end of the fireproof wire and wrap it around the positioning groove 51 of the positioning block 5 at the other end of the testing chamber 21. At this time, the fireproof wire part in the testing chamber 21 is in a straight, suspended state. Then, close the cover 3 and fasten it, so that the extrusion strip 32 extrudes the surface of the fireproof wire, thereby extruding the fireproof wire in the positioning groove 51. The wire is pressed tightly, and the fire-resistant wire in the groove 23 is sealed. Then, the spray gun body 22 is turned on, and the spray gun body 22 sprays fire to burn the fire-resistant wire. At this time, the user starts the timer to record the melting time of the cable, thereby achieving the purpose of testing the fire resistance of the fire-resistant wire. By setting two axially symmetrical positioning blocks 5 at both ends of the test chamber 21 and the serpentine positioning groove 51 set in the positioning blocks 5, the fire-resistant wire can be quickly fixed in the test chamber 21 without cutting the fire-resistant wire, which improves the convenience of use. Furthermore, the adjustment groove 41, the slot 42 and the retaining ring 52 set in the adjustment seat 4 make it easy to replace different positioning blocks 5 to position fire-resistant wires with different outer diameters, increasing the applicability.
