[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0029] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0030] Example 1

[0031] like Figure 1-Figure 3As shown, the fire line pipe fixing hoop dedicated to the steel structure grid includes a mounting plate 1 and a plurality of clamping members 2, wherein the plurality of clamping members 2 are arranged along the axial direction of the fire line pipe, and the fire line pipe is fixed at a plurality of positions, so that the fire line pipe can be fixed better by fixing the fire line pipe at a plurality of positions. The mounting plate 1 can be fixed to the steel structure grid by bolts or welded to the steel structure grid, and the clamping members 2 are used to clamp the fire line pipe, wherein each clamping member 2 includes a connecting block 3, a base 5 and a clamp 12.

[0032] Specifically, in this embodiment, the connection block 3 has a rotation-stopping plane that fits with the inner wall of the channel 6 to prevent the base 5 from rotating on the connection block 3. For example, the connection block 3 is a rectangular parallelepiped. Of course, other blocks are also feasible, such as a cube, a hexagonal prism, and a heptagonal prism. When there is only one connection block 3 in each clamp 2, the connection block 3 is a rectangular parallelepiped to ensure that the base 5 will not rotate after being fixed.

[0033] Specifically, the connecting block 3 is installed on the mounting plate 1 by welding, and the upper end of the connecting block 3 has a wedge-shaped surface. A first groove 4 is provided on the outer wall of the connecting block 3. It should be known that the number of the first grooves 4 can also be two, and the two first grooves 4 are symmetrically arranged on the outer wall of the connecting block 3. In this way, by setting a plurality of first grooves 4, the base 5 is better fixed. The two first grooves 4 are arranged along the left-right direction. The left-right direction in this embodiment is the width direction of the mounting plate 1, the front-to-back direction is the length direction of the mounting plate 1, and the up-down direction is the thickness direction of the mounting plate 1.

[0034] The bottom of the base 5 is provided with a channel 6 which is sleeved on the outside of the connection block 3. The axial direction of the channel 6 is perpendicular to the plate surface of the mounting plate 1. When the device is used, the axial direction of the channel 6 can also be designed to be inclined in the direction opposite to the gravity direction, so that the base 5 can be better fixed on the steel structure grid. For the connection block 3, the installation direction should be consistent with the channel 6. The number of channels 6 is consistent with the number of the connection block 3. The inner wall of the channel 6 is provided with second grooves 7 which are consistent with the number of the first grooves 4. The extension direction of the second grooves 7 is the left-right direction and is perpendicular to the extension direction of the channel 6. A spring pin is installed in the second groove 7. The spring pin is used to extend into the first groove 4 when the connection block 3 is inserted into the channel 6 to fix the base 5 on the connection block 3.

[0035] The clamp 12 is installed on the base 5, and the clamp 12 is used to tighten the fire-fighting line pipe.

[0036] By setting a connecting block 3 on the mounting plate 1, when the fire-fighting pipe needs to be installed, the base 5 can be fixed by simply pressing the base 5 toward the connecting block 3, and then the clamp 12 can be used to tighten the fire-fighting pipe. At the same time, because the upper end of the connecting block 3 has a wedge-shaped surface, the spring pin in the base 5 can slide into the first groove 4 through the wedge-shaped surface, thereby fixing the base 5.

[0037] Specifically, the spring pin includes a compression spring 8, a pin rod 9 and a pin head 10. The compression spring 8 and the pin rod 9 are both installed in the second groove 7. The compression spring 8 is sleeved on the pin rod 9. The second groove 7 runs through the base 5. The second groove 7 includes a large hole groove section close to the connecting block 3 and a small hole groove section away from the connecting block 3. The large hole groove section and the small hole groove section form a step toward the connecting block 3.

[0038] The pin head 10 is slidably assembled in the large hole groove section and is used to extend into the first groove 4. The pin rod 9 is fixed on the pin head 10. The compression spring 8 is sleeved on the outside of the pin rod 9 and the compression spring 8 is elastically pressed between the step and the pin head 10. A limit head 11 is fixed on the end of the pin rod 9 away from the pin head 10. The limit head 11 is located outside the base 5. The maximum diameter of the limit head 11 is greater than the maximum diameter of the small hole groove section, which can prevent the spring pin from moving out of the second groove 7. At the same time, the bottom of the pin head 10 has a wedge surface. The wedge surface on the pin head 10 can be wedge-matched with the wedge surface on the connecting block 3, so that the pin head 10 can slide into the first groove 4 more easily. The spring pin in this embodiment can also be an elastic cylindrical pin described in the Chinese patent document with the authorization announcement number CN213117051U.

[0039] Example 2

[0040] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that, in this embodiment, each clamping member 2 includes two parallel connection blocks 3, the two connection blocks 3 are arranged along the left-right direction, and the first grooves 4 on the two connection blocks 3 are arranged along the front-back direction, and the extension direction of the second groove 7 is the front-back direction. When there are two connection blocks 3 in each clamping member 2, the base 5 can be prevented from rotating around the axis of the connection block 3. At the same time, because there are two connection blocks 3 in each clamping member 2, the shape of the connection block 3 can be any shape, including a cylinder, and the first groove 4 can be an annular groove.

[0041] Example 3

[0042] The difference between this embodiment and embodiment 1 is that the connection block 3 in this embodiment is a cylinder with a truncated cone at the upper end of the cylinder, and the outer wall of the cylinder has a first groove 4 arranged in the left-right direction to facilitate the insertion of the spring pin. However, the first groove 4 cannot be an annular groove.
