[0031] Example 1:

[0032] This embodiment provides a cable fixing fixture, such as Figure 1-Figure 4 As shown, including:

[0033] The cable fixing clamp 10 includes a supporting portion 11, an adjusting portion 12 and at least one elastic mechanism 13. The elastic mechanism 13 is arranged on the adjusting portion 12 and / or the supporting portion 11. The elastic mechanism 13 provides an elastic force to the adjusting portion 12 and / or the supporting portion 11 so that the adjusting portion 12 and the supporting portion 11 tend to approach each other. The adjusting portion 12 and / or the supporting portion 11 overcome the elastic force so that a gap portion 16 for accommodating the cable is formed between the adjusting portion 12 and the supporting portion 11.

[0034] This embodiment provides a cable fixing clamp. In the initial state, the support part 11 and the adjustment part 12 cooperate. When the cable needs to be fixed and clamped, the elastic force is overcome by the adjustment part 12 and / or the support part 11 to form a gap part 16 for accommodating the cable between the adjustment part 12 and the support part 11. The cable fixing clamp 10 is placed in the open state, and the cable is placed in the gap part 16. Then, the elastic mechanism 13 provides elastic force to the adjustment part 12 and / or the support part 11 so that the adjustment part 12 has a tendency to approach the support part 11, so that the support part 11 and the adjustment part 12 match to clamp the cable.

[0035] The adjustment portion 12 and / or the support portion 11 overcome the elastic force so that a gap portion 16 is formed between the support portion 11 and the adjustment portion 12 to accommodate the cable. The size of the gap portion 16 can be adjusted according to the diameter of the cable. Therefore, this embodiment can fix and clamp the cable without being limited to the diameter of the cable.

[0036] In this embodiment, Figure 1-Figure 3As shown, the support portion 11 has a groove 111, and the adjustment portion 12 has a protrusion 121 that matches the shape of the groove 111. In the initial state, the groove 111 and the protrusion 121 match. When it is necessary to fix and clamp the cable, the adjustment portion 12 and / or the support portion 11 overcome the elastic force to form a gap portion 16 for accommodating the cable between the protrusion 121 and the groove 111, so that the cable fixing clamp 10 is in the open state, and the cable is placed in the gap portion 16. Then, the elastic mechanism 13 provides elastic force to the adjustment portion 12 and / or the support portion 11 so that the protrusion 121 has a tendency to approach the groove 111, so that the groove 111 and the protrusion 121 match to clamp the cable.

[0037] In this embodiment, Figure 1-Figure 3 As shown, the groove 111 is a trapezoidal groove, and the protrusion 121 is a trapezoidal protrusion 121 , so that this embodiment can adapt to cables of various diameters, and the shapes of the trapezoidal groove and the trapezoidal protrusion 121 match.

[0038] In order to prevent the cable from being damaged, the cable fixing fixture 10 provided in this embodiment further includes a cable protection portion, which is a smooth portion or a silicone pad provided on the support portion 11 and the adjustment portion 12. Specifically, Figure 5 and Figure 6 As shown, a first smooth portion 1111 is provided on the inner side of the groove 111, and a second smooth portion 1211 is provided on the outer side of the protrusion 121. The first smooth portion 1111 and the second smooth portion 1211 are arranged opposite each other and have matching shapes. Both the first smooth portion 1111 and the second smooth portion 1211 have smooth surfaces and are free of burrs. When the groove 111 is a trapezoidal groove and the protrusion 121 is a trapezoidal protrusion 121, the first smooth portion 1111 is provided at the bottom of the trapezoidal groove, and the second smooth portion 1211 is provided at the top of the trapezoidal groove 111, so that the bottom of the trapezoidal groove and the top of the trapezoidal groove 111 are arranged opposite each other and have matching shapes. The first smooth portion 1111 and the second smooth portion 1211 can have an arc-shaped or other streamlined structure, which is not limited to this in this embodiment, and further protect the outer surface of the cable to prevent damage to the cable.

[0039] In this embodiment, Figure 1-Figure 3 As shown, the elastic mechanism 13 includes a bracket 131 and a spring 132. The bracket 131 is fixed to the support part 11. The bracket 131 has a force-bearing part 1311. The force-bearing part 1311 is arranged on the side of the adjustment part 12 away from the support part 11. One end of the spring 132 is arranged on the adjustment part 12, and the other end of the spring 132 is arranged on the force-bearing part 1311. The extension direction of the spring 132 is parallel to the moving direction of the adjustment part 12. The spring 132 provides elastic force so that the adjustment part 12 and the support part 11 tend to approach each other.

[0040] Specifically, the extension direction of the spring 132 is parallel to the movement direction of the protrusion 121 . Thus, the spring 132 provides elastic force to the adjustment portion 12 so that the spring 132 provides a tendency for the protrusion 121 to approach the groove 111 .

[0041] In this embodiment, Figure 1-Figure 3 As shown, in order to limit the moving direction of the spring 132, a support column 133 is also included, through which the movement direction of the spring 132 can be guided. The support column 133 is fixed to the force-bearing part 1311, and the spring 132 is sleeved on the support column 133, and the extension direction of the support column 133 is parallel to the moving direction of the adjustment part 12, thereby making the moving direction of the spring 132 parallel to the moving direction of the adjustment part 12, preventing the moving direction of the spring 132 from deviating, and ensuring the coordination between the adjustment part 12 and the support part 11.

[0042] Specifically, the extension direction of the support column 133 is parallel to the movement direction of the protrusion 121, thereby making the movement direction of the spring 132 parallel to the movement direction of the protrusion 121, preventing the movement direction of the spring 132 from being offset, thereby preventing the movement direction of the adjustment portion 12 from being offset, and preventing the protrusion 121 from not being completely matched with the groove 111. During use, by pulling the adjustment portion 12, the spring 132 is compressed on the support column 133, thereby facilitating the movement of the adjustment portion 12 on the support column 133, so that a gap portion 16 for accommodating the cable is formed between the protrusion 121 and the groove 111. When the cable is completely placed in the gap portion 16, the adjustment portion 12 is released, and the elastic mechanism 13 provides elastic force to the adjustment portion 12 so that the protrusion 121 is close to the groove 111, thereby compressing the cable.

[0043] In this embodiment, Figure 1-Figure 3 As shown, a hole 122 is provided on the adjustment portion 12, and a support column 133 passes through the adjustment portion 12 and the support column 133 through the hole 122, and one end of the support column 133 is fixed to the bracket 131, and the other end of the support column 133 is fixed to the support portion 11, so that the adjustment portion 12 can move along the support column 133, thereby adjusting the size of the gap portion 16, so that the gap portion 16 can adapt to single cables of different diameters.

[0044] Specifically, in order to facilitate the sliding of the adjusting portion 12 on the supporting column 133 , the adjusting portion 12 is clearance-matched with the hole 122 , so that there is a moving space in the hole 122 for the adjusting portion 12 to move conveniently.

[0045] In this embodiment, the number of the elastic mechanisms 13 is more than two, and the plurality of elastic mechanisms 13 are symmetrically distributed on the outside of the adjustment portion 12. Specifically, the plurality of elastic mechanisms 13 are symmetrically distributed on the outside of the protrusion 121.

[0046] In this embodiment, Figure 1-Figure 3As shown, it further includes a fixture beam 14. The fixture beam 14 is fixed to the support portion 11. The bracket 131 is fixed to the support portion 11 by being fixed to the fixture beam 14. The fixture beam 14 is used for fixedly connecting to a single-cable vertical combustion test device.

[0047] The fixture beam 14 is fixed to the support portion 11 by means such as bolts, and this embodiment does not limit this.

[0048] The bracket 131 is fixed to the fixture beam 14 by means such as bolts, and this embodiment does not limit this.

[0049] In the embodiment of the present utility model, the fixture beam 14 is a plate-like structure. At least one mounting hole 122 is provided on the fixture beam 14. The fixture beam 14 is fixed to the single-cable vertical combustion test device by means such as bolts passing through the mounting hole 122, and this embodiment does not limit this.

[0050] In this embodiment, as Figure 1 and Figure 7 shown, the bracket 131 further includes a connecting portion 1312 and a fixing portion 1313. The force-bearing portion 1311, the connecting portion 1312, and the fixing portion 1313 are detachably connected, fixedly connected, or integrally formed in sequence, and this embodiment does not limit this. The fixing portion 1313 is fixed to the fixture beam 14, and the connecting portion 1312 is used to connect the force-bearing portion 1311 and the fixing portion 1313.

[0051] In the specific implementation manner of this embodiment, as Figure 7 shown, the force-bearing portion 1311, the connecting portion 1312, and the fixing portion 1313 are all plate-like structures, and the force-bearing portion 1311, the connecting portion 1312, and the fixing portion 1313 are connected in sequence to form a "C" shape.

[0052] In this embodiment, as Figure 1-Figure 3 shown, it further includes a handle 15. The handle 15 is fixed to the adjustment portion 12. During use, by pulling the handle 15 to pull the adjustment portion 12 to overcome the elastic force of the elastic mechanism 13, a gap portion 16 for accommodating the cable is formed between the protrusion 121 and the groove 111. When the cable is completely placed in the gap portion 16, release the handle 15, and the elastic mechanism 13 provides an elastic force for the adjustment portion 12 to make the protrusion 121 approach the groove 111, thereby pressing the cable tightly.

[0053] Specifically, the handle 15 is fixed to the adjustment portion 12 by means such as threaded connection, snap connection, or riveting, and this embodiment does not limit this.

[0054] In this embodiment, in order to prevent the groove 111 from deviating relative to the protrusion 121 when pulling the adjustment portion 12, the handle 15 is fixed to the center of the protrusion 121.

[0055] In this embodiment, the protrusion 121 in the adjustment block is a plate-shaped structure, which reduces the mass of the adjustment block and makes it more convenient to pull the handle 15.

[0056] Example 2:

[0057] like Figure 8 The difference between this embodiment and the first embodiment is that at least two cable fixing fixtures 10 are coaxially and vertically arranged in sequence, which can solve the problem that the existing device is difficult to ensure that the cables are completely vertical and accurately aligned.
