Description

Technical Field

[0001] This application relates to the technical field of aerosol equipment, and in particular to a wire harness fixing fixture for aerosols. Background Technology

[0002] Aerosol fire extinguishing products use a spray device to propel solid extinguishing agents, such as thermal aerosol generators or cold aerosol dry powder, under high pressure through an open nozzle, thus introducing them into the fire extinguishing environment. These extinguishing agents, with their small particle size and high surface energy, can rapidly absorb the heat released by the combustion reaction, lower the temperature of the fire source, and inhibit the free radical chain reaction during combustion, thereby stopping the combustion reaction and achieving the effect of extinguishing the fire.

[0003] like Figure 1 The aerosol canister 14 has a wiring groove 16 at its end for wiring. A wire for triggering the ignition component is connected within the wiring groove 16. Depending on the application, a temperature switch may be installed within the wiring groove 16 to determine whether the aerosol has been ejected via signal feedback. Whether the wires are from the aerosol canister 14 itself or from the temperature switch, hot melt adhesive needs to be poured into the wiring groove 16 to enhance the connection strength of the wires on the aerosol canister 14. A gland 15 is threaded onto the external end of the wiring groove 16, and the wires pass through the through-holes in the gland 15.

[0004] When applying hot melt adhesive, the operator often holds the wire. After the hot melt adhesive cures, the wire may be biased towards one side of the wiring groove 16. This can cause the inner edge of the gland 15 to rub against the wire when installing the gland 15, potentially cutting the wire sheath and damaging the wire core, which is detrimental to the normal use of the aerosol. Utility Model Content

[0005] To reduce the misalignment of the wiring harness within the wiring slot of the aerosol can, which could cause friction between the inner edge of the gland and the wire, resulting in cuts to the wire sheath and damage to the wire core, this application provides a wiring harness fixing fixture for aerosols.

[0006] The aerosol wire harness fixing fixture provided in this application adopts the following technical solution:

[0007] A wire harness fixing fixture for aerosols includes a connecting seat for connecting to an aerosol can body, the connecting seat having a support arm, and the support arm having a groove for limiting or positioning the wire harness.

[0008] By adopting the above technical solution, the connector is connected to the aerosol can, and a support arm and groove are set on the connector to effectively limit or position the wire harness. This allows the wire harness to be located in the middle position within the wiring groove of the aerosol can, reducing the friction between the inner wall edge of the gland and the wire during installation, which could cause the wire sheath to be cut and the wire core to be damaged. This helps to maintain the stability and safety of the wire harness during the use of aerosol equipment.

[0009] Optionally, a baffle is movably provided on the support arm, the baffle being used to block the opening of the groove to prevent the wire harness from detaching from the groove.

[0010] By adopting the above technical solution, a baffle is movably installed on the support arm to cover the opening of the groove. This design further enhances the reliability of the support arm in fixing the wire harness and makes it easier to position the wire harness in the center of the wiring groove.

[0011] Optionally, the support arm is provided with a first extension and the baffle is provided with a second extension. The first extension and the second extension can be spliced ​​together to form a conduit. The conduit is used to position and guide the wire harness and position the wire harness at the center of the wiring groove of the aerosol can.

[0012] By adopting the above technical solution, the first extension and the second extension are spliced ​​together to form a conduit, achieving precise positioning and guidance of the wire harness and ensuring that the wire harness can be accurately connected to the center position of the wiring port on the aerosol can. This improves the stability of the wire harness positioning and reduces equipment failures caused by misalignment of the wire harness connection position.

[0013] Optionally, the support arm has a recessed groove, the baffle is disposed in the recessed groove, and the support arm is provided with a limiting component for confining the baffle within the recessed groove.

[0014] By adopting the above technical solution, a groove is opened on the support arm, allowing the baffle to be installed within the groove, and a limiting component is provided to restrict the sliding of the baffle. This design allows the position of the baffle to be flexibly adjusted according to actual needs to accommodate wire harnesses of different sizes or shapes, improving the versatility and flexibility of the tooling.

[0015] Optionally, a positioning block is fixedly connected to the bottom wall of the trough facing the baffle, and a positioning groove is provided on the bottom wall of the trough for the positioning block to engage.

[0016] By adopting the above technical solution, the positioning block on the baffle and the positioning groove on the bottom wall of the settling tank further enhance the stability of the baffle in the settling tank, prevent the baffle from sliding on its own under vibration or external force, and ensure the durability and reliability of the wire harness fixation.

[0017] Optionally, the limiting component includes an elbow clamp disposed on the support arm, the elbow clamp being used to press the baffle against the support arm.

[0018] By adopting the above technical solution, a simple and effective limiting method is provided by using an elbow clamp to hold the baffle against the support arm. The clamping action ensures the stability of the baffle position while facilitating operation and adjustment.

[0019] Optionally, the limiting component includes a limiting rod rotatably connected to the support arm, which, when flipped, can press the baffle against the sinkhole.

[0020] By adopting the above technical solution, the design of the limiting rod provides a more flexible limiting method, which can fix the baffle by flipping the limiting rod. This design is convenient and quick, and can ensure the stability of the baffle in the settling tank.

[0021] Optionally, the end of the limiting rod may be detachably provided with an elastic pad, and the limiting rod may be flipped to press the elastic pad against the baffle.

[0022] By adopting the above technical solution, an elastic pad is set at the end of the limiting rod. When the limiting rod is flipped, the elastic pad can provide a more uniform and gentler pressure, avoiding damage to the baffle or support arm caused by rigid contact and improving the service life of the tooling.

[0023] Optionally, the limiting component includes a magnetic suction component disposed between the baffle and the settling trough, wherein the baffle is fixed in the settling trough by the magnetic suction component.

[0024] By adopting the above technical solution, the magnetic force secures the baffle within the settling tank, which is both convenient and reliable. At the same time, the use of magnetic components reduces the cost of tooling manufacturing and maintenance.

[0025] Optionally, the connecting seat is provided with a limiting hole for fixing the aerosol can body.

[0026] By adopting the above technical solution, a limiting hole is provided on the connector to fix the aerosol can. This design ensures a stable connection between the aerosol can and the tooling, preventing the wiring harness connection from becoming misaligned due to loosening or displacement of the can. At the same time, the limiting hole design also facilitates the quick installation and disassembly of the aerosol can.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The connector connects to the aerosol can and has a support arm and groove on it, which effectively limits or positions the wire harness, so that the wire harness can be located in the middle position in the wiring groove of the aerosol can. This reduces the friction between the inner edge of the gland and the wire when installing the gland, which can cause the outer sheath of the wire to be cut and the core to be damaged.

[0029] 2. The first extension and the second extension are spliced ​​together to form a conduit, which realizes the precise positioning and guidance of the wire harness, ensuring that the wire harness can be accurately connected to the center position of the wiring port of the aerosol can.

[0040] The following is in conjunction with the appendix Figure 2-9This application will be described in further detail. Example 1

[0041] This application discloses a wire harness fixing fixture for aerosols. For example... Figure 2 and Figure 3 The aerosol wiring harness fixing fixture includes a connector 1. The lower end of the connector 1 is used to connect to the aerosol can 14. The lower end of the connector 1 is provided with a limiting hole 13 or a limiting groove for limiting the aerosol can 14. In this embodiment, the connector 1 is provided with a limiting hole 13, and the aerosol can 14 is placed in the limiting hole 13 to fix the position of the aerosol can 14 on the connector 1, reducing the problem of the aerosol can 14 shaking or shifting under external force when filling the wiring groove 16 of the aerosol can 14 with glue.

[0042] The upper end of the connector 1 is provided with a support arm 11. Both the connector 1 and the support arm 11 are made of metal, which gives the entire device a certain strength. The connector 1 and the support arm 11 are bent into a C-shaped frame. The support arm 11 is provided with a groove 12 for accommodating the wire harness. When the wire harness extends vertically downward from the groove 12, it can extend to the middle position of the wiring groove 16 of the aerosol can 14.

[0043] A baffle 2 is movably mounted on the support arm 11. The baffle 2 is used to block the opening of the groove 12, thereby confining the wire harness within the groove 12 and improving the limiting effect of the support arm 11 on the wire harness. The baffle 2 can be slidably mounted on the support arm 11, hinged to the support arm 11, or installed on the support arm 11 through other connecting components. In this embodiment, a recessed groove 21 is formed on the upper surface of the support arm 11 near the opening of the groove 12, and the recessed groove 21 is also set as an opening corresponding to the opening of the groove 12. The baffle 2 can be disposed within the recessed groove 21 to achieve the blocking effect on the opening of the groove 12. A limiting component 3 is provided on the support arm 11 to confine the baffle 2 within the recessed groove 21.

[0044] like Figure 3 and Figure 4 The lower end of the support arm 11 is vertically fixedly connected to a first extension 22 with a semi-circular cross-section, and the baffle 2 is fixedly connected to a second extension 23 with a semi-circular cross-section. When the baffle 2 is located in the settling tank 21, the first extension 22 and the second extension 23 are spliced ​​together to form a conduit 24, which is used to guide the wire harness, thereby guiding the wire harness to the middle position of the wiring slot 16 of the aerosol tank 14.

[0045] like Figure 2 and Figure 3The limiting component 3 includes an elbow clamp 4 fixedly connected to the support arm 11. The movable part of the elbow clamp 4 moves vertically and faces the sink 21. The operator can flip the handle of the elbow clamp 4 to press the movable part of the elbow clamp 4 against the baffle 2, thereby fixing the position of the baffle 2 in the sink 21.

[0046] The implementation principle of this application embodiment is as follows: the aerosol can 14 is positioned by the connecting seat 1, and the wire harness is limited by the conduit 24 formed by the splicing of the first extension 22 and the second extension 23, so that the operator can fix the wire harness with glue and make the fixed wire harness located in the middle of the wiring groove 16 of the aerosol can 14, reducing the friction between it and the inner ring of the gland 15, which would cause the outer sheath of the wire harness to be cut or broken. Example 2

[0047] like Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that the limiting component 3 includes a limiting rod 6 rotatably connected to the upper surface of the support arm 11, and one or more limiting rods 6 can be provided. The rotation axis of the limiting rod 6 is vertically arranged, and the free end of the limiting rod 6 can be flipped to extend into the sink 21.

[0048] like Figure 7 The free end of the limiting rod 6 is detachably provided with an elastic gasket 61. In this embodiment, the elastic gasket 61 is made of rubber.

[0049] The operator can flip the elastic pad 61 to the side of the baffle 2 away from the sink 21 by flipping the limiting rod 6. Under the action of the limiting rod 6, the baffle 2 is confined within the sink 21, thus fixing the position of the baffle 2 within the sink 21. In addition, the elastic pad 61 is made of rubber to increase the friction between the elastic pad 61 and the baffle 2, thereby improving the limiting effect of the limiting rod 6 on the baffle 2.

[0050] like Figure 6 A positioning block 5 is provided on the baffle 2 facing the bottom wall of the sink 21. A positioning groove 51 is provided on the bottom wall of the sink 21. When the baffle 2 is placed in the sink 21, the positioning block 5 is embedded in the positioning groove 51, which facilitates the positioning of the baffle 2 in the sink 21. Example 3

[0051] like Figure 8 and Figure 9The difference between this embodiment and embodiment 2 is that the limiting component 3 includes a magnetic attraction component 7 disposed between the baffle 2 and the bottom wall of the sink 21. The magnetic attraction component 7 includes a magnet 71, which can be disposed on the baffle 2 and / or the bottom wall of the sink 21. In this embodiment, the magnet 71 is fixedly connected to the baffle 2, and a metal sheet 72 for the magnet 71 to attract is embedded in the bottom wall of the sink 21. When the baffle 2 is disposed in the sink 21, the magnet 71 attracts the metal sheet 72, thereby fixing the position of the baffle 2 in the sink 21.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
