Description

Technical Field

[0001] The utility model relates to a mounting component of a fire detector, in particular to a waterproof base of a fire detector. Background Art

[0002] Fire detectors are a crucial component of automatic fire alarm systems, used to monitor the environment for fires and issue timely alerts. During installation, fire detectors are secured to a pre-set panel on the wall via a base. The lower end of the base houses the fire detector's detection circuit. Wiring for this circuit must pass through the base and connect to terminals on the pre-set panel. To prevent ambient water from entering the detection circuit through the base, the base is typically sealed for watertightness.

[0003] The traditional sealing method involves applying a soft rubber layer to the base to seal the reserved wire holes. During installation, workers use a screwdriver or other tool to pierce the rubber layer and pass the wires for the detection circuit through it to connect to the terminals. However, this method is prone to tearing after the rubber layer is pierced, and the inner edge of the hole after the puncture is irregular. As a result, a gap still exists between the rubber layer and the wire after passing through the rubber layer, which cannot achieve a complete seal. There is still a risk that ambient water can enter the base detection circuit through the gap, causing the fire detector to fail. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a waterproof base for a fire detector. By arranging a soft rubber tube cap on the soft rubber layer, the end of the soft rubber tube cap is cut off when in use, and the wire is passed through the end of the soft rubber tube cap and wrapped to achieve sealing. The operation is simple and the sealing effect is good.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] Furthermore, the soft rubber tube cap is a cylindrical structure.

[0010] Furthermore, a shear mark ring is provided on the outer periphery of the soft rubber tube cap; and there is at least one shear mark ring.

[0011] Furthermore, the base body is provided with an array of mounting holes, and a second soft plastic sheet is provided in the mounting holes to seal the mounting holes.

[0012] Furthermore, a strip groove is opened on the base body, the threading window and the mounting hole are connected through the strip groove, the strip groove is filled with a soft rubber strip, and the soft rubber strip is connected to the first soft rubber sheet and the second soft rubber sheet as a whole.

[0013] Furthermore, the inner periphery of the threading window is provided with a flange, and the outer periphery of the first soft film is nested on the flange.

[0014] Furthermore, the threading window is arranged at the center of the base body, and the mounting holes are located at two opposite ends of the outer periphery of the threading window.

[0015] Furthermore, there is at least one shear mark circle.

[0016] Furthermore, drainage holes are provided on the outer periphery of the bottom plate body.

[0025] The following will be combined with the accompanying drawings to describe the embodiments of the present invention in detail so that the purpose, features and advantages of the present invention can be more clearly understood. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0026] like Figure 1 - Figure 4 The present invention provides a waterproof base for a fire detector, comprising a base body 1, a wire threading window 101 formed on the base body 1, a first soft plastic sheet 2 provided in the wire threading window 101 to seal the window, and a soft plastic tube cap 3 arrayed on one side of the first soft plastic sheet 2, the open end of the soft plastic tube cap 3 passing through the first soft plastic sheet 2.

[0027] Specifically, the base body 1 is in the shape of a circular disk, with its outer edge forming a trumpet shape. The threading window 101 is rectangular and is located at the center of the base body 1. The soft rubber tube cap 3 is connected to the first soft rubber sheet 2 as a whole.

[0028] One end of the soft rubber tube cap 3 is open and the other end is closed. The closed end extends toward the outer peripheral end of the first soft rubber sheet 2. After the base body 1 is installed, the closed end faces downward, and the wire enters the soft rubber tube cap 3 from the open end for sealing and then extends out from the closed end after being cut.

[0029] Furthermore, at least one end of the soft rubber tube cap 3 extends out of the first soft rubber sheet 2. Of course, as a preferred embodiment, both ends of the soft rubber tube cap 3 extend out of threading windows 101, which can achieve a better sealing effect.

[0030] Furthermore, in order to facilitate the fixation of the first soft film 2, a flange is provided on the inner periphery of the threading window 101, and the outer periphery of the first soft film 2 is nested on the flange. A groove is provided on the outer periphery of the first soft film 2, and the flange is nested in the groove.

[0031] Furthermore, the soft rubber tube cap 3 is a cone-shaped tube structure. The cone is a circular cone, and the outer diameter of the open end of the cone is larger than the outer diameter of the closed end.

[0032] As a preference, the top end of the cone is a closed plane.

[0033] Furthermore, it is also possible to select that the soft rubber tube cap 3 is a cylindrical structure, and the cylindrical tube is a circular cylindrical tube. The outer diameters of the open end and the closed end of the cylindrical tube are the same.

[0034] Furthermore, to facilitate positioning of the cutting length of the soft rubber tube cap 3, a cutting mark ring is provided on the outer circumference of the soft rubber tube cap 3. Cutting can be performed along the edge of the cutting mark ring. Multiple cutting marks can be provided, and if multiple cutting marks are provided, they are spaced apart. Cutting marks at different positions represent the corresponding cutting heights of the soft rubber tube cap 3.

[0035] As a preferred embodiment, when the soft rubber tube cap 3 is a conical tube structure, the position of the shear mark ring can also be used to mark the inner diameter of the soft rubber tube cap 3. At this time, multiple shear mark rings can be set, and different shear mark rings correspond to different inner diameters of the soft rubber tube cap 3, so that the soft rubber tube cap 3 can be sheared according to the specifications of the wire, so that the inner periphery of the soft rubber tube cap 3 and the outer periphery of the wire form a sealed fit.

[0036] Furthermore, the base body 1 is provided with an array of mounting holes 102, within which a second soft film 4 is provided to seal the mounting holes 102. The mounting holes 102 are used to connect to the reserved panel on the ceiling via connecting screws. During installation, the connecting screws can directly pass through the second soft film 4, which seals the outer periphery of the connecting screws.

[0037] Furthermore, to facilitate securing the second soft film 4 and the first soft film 2 and prevent them from falling off, a strip-shaped channel 103 is provided on the base body 1, with the bottom surface of the strip-shaped channel 103 located within the base body 1. The threading window 101 and the mounting hole 102 are connected through the strip-shaped channel 103, which is filled with a soft rubber strip 5, which is integrally connected to the first and second soft films 2 and 4. During the production of the waterproof base, the second soft film 4, the first soft film 2, and the strip-shaped channel 5 are injection-molded onto the waterproof base at one time.

[0038] As a preferred embodiment, the strip-shaped groove 103 passes through the upper and lower end surfaces of the base body 1 , and the upper and lower surfaces of the soft rubber strip 5 are flush with the upper and lower end surfaces of the base body 1 .

[0039] Furthermore, the first soft rubber sheet 2, the second soft rubber sheet 4, the soft rubber strip 5, and the soft rubber cap 3 are all made of the same soft rubber material. The soft rubber material may be selected from, but is not limited to, rubber, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), thermoplastic rubber (TPR), and other soft rubber or elastic materials.

[0040] Furthermore, a wire pass-through window 101 is located in the center of the base body 1, and mounting holes 102 are located at opposite ends of the periphery of the wire pass-through window 101. There is only one wire pass-through window 101, and multiple mounting holes 102 are provided. These multiple mounting holes 102 are arranged in pairs on the base body 1 around the periphery of the wire pass-through window 101, with each pair of opposing mounting holes 102 forming a group. When installing the base body 1, simply select the appropriate pair of opposing mounting holes 102 based on the reserved panel positioning holes.

[0041] Furthermore, a drainage hole 6 is opened on the outer periphery of the base body 1 , and the drainage hole 6 passes through the inner and outer peripheries of the base body 1 .

[0042] Specifically, a ring-shaped array of drainage holes 6 is arranged at the bottom of the trumpet mouth of the outer peripheral edge of the base body 1. The drainage holes 6 are connected to the upper surface of the base body 1. When environmental water gathers in the base body 1, the environmental water can be discharged through the drainage holes 6 around it, ensuring that no environmental water will gather in the base body 1.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
