Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to a mounting bracket and a fire extinguishing device. Background Technology

[0002] Our company offers several flat-type fire extinguishing devices, and our existing devices can accommodate installation in most cabinets and cabins. For example, Chinese patent document CN222488679U discloses a high-protection-level flat aerosol fire extinguishing device from our company. This device is installed using mounting ears on the casing, ensuring the extinguishing device is flush against the surface of the mounting location after installation. According to the XF499.1-2010 standard, the casing temperature of a temperature-limited suspended fire extinguishing device should not exceed 200℃. Our existing flat-type aerosol fire extinguishing devices incorporate heat-insulating adhesive inside, ensuring the casing temperature is well below 200℃ during use. However, in special scenarios, such as when the fire extinguishing device is installed on a non-heat-resistant plastic casing, the requirements for the casing temperature are even higher. For example, if the casing temperature needs to be ≤90℃, the fire extinguishing device casing must not come into contact with the plastic casing.

[0003] In addition, once the existing flat-type fire extinguishing device is installed through the mounting ears, the position of the nozzle cannot be adjusted. Since the capacity of the extinguishing agent in the flat-type fire extinguishing device is limited, there is a problem that the fire extinguishing effect may be reduced if the nozzle is not adjusted to the appropriate position.

[0004] Furthermore, when fire extinguishing devices are installed in environments with vibration, such as inside new energy vehicles, how to prevent the mounting screws from loosening is also a problem that needs to be solved.

[0005] To address the aforementioned technical issues, our technical personnel proposed using a bracket system for installing the fire extinguishing device. This involves considering the ease and reliability of bracket installation. Our existing bracket structure, such as the clamp-type fire extinguishing device bracket disclosed in CN219700901U, is relatively complex. Furthermore, the two curved plates require aligned holes when installing the fixing bolts, and the lack of limiting mechanisms makes it inconvenient to use. Additionally, the bolts on this type of bracket are prone to loosening under vibration. Therefore, our technical personnel designed the mounting bracket of this utility model. Utility Model Content

[0006] The purpose of this utility model is to provide a mounting bracket to solve the problems of ease of installation and reliability of the bracket structure.

[0007] Another objective of this invention is to provide a fire extinguishing device that is installed using this mounting bracket.

[0008] To achieve the above objectives, this utility model provides a mounting bracket, including a first mounting component and a second mounting component. The second mounting component is a plate-shaped structure, and at least one mounting hole is provided at each of its two ends. The first mounting component includes a clamping part and connecting parts connected to both ends of the clamping part. Connecting holes corresponding to the mounting holes are provided on the connecting parts at both ends. A notch is provided on one side of the connecting hole, and an upwardly extending limiting part is provided on one side of the mounting hole. When the limiting part is inserted into the notch, the connecting hole is aligned with the mounting hole.

[0009] The limiting part and the second mounting part are either separately welded or integrally formed.

[0010] The clamping part is an arc-shaped plate structure.

[0011] The clamping part includes a first plate and a second plate. The two second plates are respectively fixed to both ends of the first plate. The connecting part is fixed to the second plate. There is a space between the first plate and the second mounting member for clamping the body of the fire extinguishing device.

[0012] It also includes a mounting screw, which has a head and a threaded portion connected to the head. The outer circumferential wall of the head is provided with a limiting groove at one end near the threaded portion. The limiting portion extends beyond the connecting portion by a certain height and can be elastically engaged into the limiting groove.

[0013] The bottom wall of the limiting groove is parallel to the tangent of the outer circumferential wall of the head. The limiting groove is provided with a limiting surface on one side of the mounting screw rotation direction, and the other side of the limiting groove extends to the outer circumferential wall of the head.

[0014] The angle between the limiting surface and the bottom wall is not greater than 90° and not less than 10°.

[0015] The outer circumferential wall of the head has a chamfer at one end near the screw.

[0016] Thermal insulation cotton is installed on the upper side of the second mounting component, or on the side opposite to the first and second mounting components.

[0017] A fire extinguishing device includes a fire extinguishing device body, wherein the fire extinguishing device body is installed using the aforementioned mounting bracket.

[0018] Compared with the prior art, this utility model has the following technical effects:

[0019] 1. This utility model uses a first mounting member and a second mounting member to clamp and install the fire extinguishing device body. The structure is simple. When the installation position is fixed, the installation position of the fire extinguishing device body can be adjusted between the first and second mounting members without tightening the mounting screws. This allows the nozzle of the fire extinguishing device body to be adjusted to a suitable range from the expected ignition point, ensuring the fire extinguishing effect. Simultaneously, a notch is provided on one side of the connecting hole, and an upwardly extending limiting part is provided on one side of the mounting hole. When the limiting part is inserted into the notch, the connecting hole and the mounting hole are aligned, and the first mounting member is limited on the second mounting member. The first and second mounting members are less likely to slip or misalign, facilitating the insertion of mounting screws through the connecting hole and the mounting hole for installation, making installation more convenient.

[0020] 2. This utility model prevents the mounting screw from loosening under vibration by elastically engaging the limiting part into the limiting groove of the mounting screw.

[0021] 3. This utility model separates the bottom of the fire extinguishing device body from the mounting surface by installing heat insulation cotton on the upper side of the second mounting component, or by installing heat insulation cotton on both the opposite sides of the first and second mounting components, thereby reducing the impact of the shell temperature on the mounting surface.

[0038] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0039] Example 1:

[0040] See Figure 1-4 A mounting bracket includes a first mounting member 10 and a second mounting member 20. The second mounting member 20 has a plate-like structure and two mounting holes 21 are respectively provided at both ends of the second mounting member 20. The first mounting member 10 includes a clamping part 11 and connecting parts 12 respectively connected to both ends of the clamping part 11. The connecting parts 12 at both ends are respectively provided with connecting holes 13 corresponding to the mounting holes 21. A notch 14 is provided on one side of the connecting hole 13, and an upwardly extending limiting part 22 is provided on one side of the mounting hole 21. When the limiting part 22 is inserted into the notch 14, the connecting hole 13 is aligned with the mounting hole 21.

[0041] The fire extinguishing device body 40 is clamped and installed by the first mounting member 10 and the second mounting member 20. The structure is simple. When the installation position is fixed, the installation position of the fire extinguishing device body 40 can be adjusted between the first mounting member 10 and the second mounting member 20 without tightening the mounting screws 30. This allows the nozzle of the fire extinguishing device body 40 to be adjusted to a suitable range from the expected ignition point, ensuring the fire extinguishing effect. Simultaneously, a notch 14 is provided on one side of the connecting hole 13, and an upwardly extending limiting part 22 is provided on one side of the mounting hole 21. When the limiting part 22 is inserted into the notch 14, the connecting hole 13 and the mounting hole 21 are aligned, and the first mounting member 10 and the second mounting member 20 are less likely to slip, facilitating the insertion of the mounting screws 30 into the connecting hole 13 and the mounting hole 21 for installation, making installation more convenient.

[0042] In this embodiment, see Figure 4 The limiting part 22 and the second mounting part 20 can be either separately welded or integrally formed. When an integrally formed structure is used, the limiting part 22 can be processed by laser cutting first, and then bent.

[0043] In one embodiment, the clamping part 11 is an arc-shaped plate structure for use with the cylindrical fire extinguishing device body 40.

[0044] In the preferred embodiment, see Figure 2 The clamping part 11 includes a first plate 111 and a second plate 112. The two second plates 112 are respectively fixed to both ends of the first plate 111. The connecting part 12 is fixed to the second plate 112. There is a space between the first plate 111 and the second mounting member 20 for clamping the fire extinguishing device body 40 so as to use the flattened fire extinguishing device body 40.

[0045] Example 2:

[0046] Based on Example 1, see Figure 1 , 5 6, 7. The mounting bracket of this utility model also includes a mounting screw 30, which has a head 31 and a threaded portion 32 connected to the head 31. The outer circumferential wall of the head 31 is provided with a limiting groove 33 at one end near the threaded portion 32. The limiting portion 22 extends a certain height beyond the connecting portion 12 and can elastically engage with the limiting groove 33. By elastically engaging the limiting portion 22 with the limiting groove 33 of the mounting screw 30, the mounting screw 30 can be prevented from loosening under vibration conditions.

[0047] Specifically, see Figure 6The bottom wall 331 of the limiting groove 33 is parallel to the tangent 311 of the outer circumferential wall of the head 31. The limiting groove 33 has a limiting surface 332 on one side of the mounting screw 30 in the rotation direction, and the other side of the limiting groove 33 extends to the outer circumferential wall of the head 31. In this way, even if the limiting part 22 is present, it will not affect the clockwise tightening of the mounting screw 30. When the limiting part 22 elastically engages in the limiting groove 33, the limiting surface 332 of the mounting screw 30 abuts against the limiting part 22, so that the mounting screw 30 will not loosen due to counterclockwise rotation.

[0048] In this embodiment, the included angle between the limiting surface 332 and the bottom wall 331 is not greater than 90° and not less than 10°.

[0049] Further, see Figure 5 The outer circumferential wall of the head 31 has a chamfer 34 at one end near the screw part 32. When the mounting screw 30 is tightened, the chamfer 34 first contacts the limiting part 22, and the limiting part 22 will elastically deform outward.

[0050] It should be noted that, see Figure 2 The limiting part 22 and the bottom 141 of the notch 14 are at a certain interval a, so that the limiting part 22 can undergo elastic deformation.

[0051] The second mounting component 20 can be made of a sheet material with good elasticity, such as stainless steel.

[0052] Example 3:

[0053] Based on Example 1 or Example 2, see Figure 8 Heat insulation cotton 50 is installed on the upper side of the second mounting component 20, or heat insulation cotton 50 is installed on both the opposite side of the first mounting component 10 and the second mounting component 20, thereby separating the bottom of the fire extinguishing device body 40 from the mounting surface and reducing the impact of the shell temperature on the mounting surface.

[0054] Of course, the heat insulation cotton 50 can also be attached to the bottom of the fire extinguishing device body 40.

[0055] In this embodiment, the heat insulation cotton 50 is a self-adhesive flame-retardant heat insulation cotton. The heat insulation cotton 50 is adhered to the first mounting member 10 and the second mounting member 20, or pasted to the bottom of the fire extinguishing device body 40. During installation, the first mounting member 10 squeezes the heat insulation cotton 50 to prevent the fire extinguishing device body 40 from loosening.

[0056] Example 4:

[0057] See Figure 8 , 9 The present invention also provides a fire extinguishing device, including a fire extinguishing device body 40, which is installed using the aforementioned mounting bracket.

[0058] The method of use or principle of this utility model:

[0059] During installation, first place the fire extinguishing device body 40 into the groove of the first mounting part 10, then cover the first mounting part 10 with the second mounting part 20. When the limiting part 22 is inserted into the notch 14, align the connecting hole 13 with the mounting hole 21, and limit the first mounting part 10 on the second mounting part 20, so that the mounting screw 30 can be inserted into the connecting hole 13 and the mounting hole 21 for installation, making the installation more convenient.

[0060] Without tightening the mounting screws 30, the installation position of the fire extinguishing device body 40 can be adjusted between the first mounting member 10 and the second mounting member 20, thereby adjusting the nozzle of the fire extinguishing device body 40 to a suitable range from the expected ignition point to ensure the fire extinguishing effect. After the position is adjusted, tighten the mounting screws 30.

[0061] When the mounting screw 30 is tightened, the chamfer 34 first contacts the limiting part 22, and the limiting part 22 will elastically deform outward. When the mounting screw 30 is tightened clockwise, the limiting part 22 elastically deforms outward. When the tightening torque of the mounting screw 30 reaches the preset range, the limiting part 22 elastically engages into the limiting groove 33, and the limiting surface 332 of the mounting screw 30 abuts against the limiting part 22, thereby preventing the mounting screw 30 from loosening by rotating counterclockwise.
