A wiring structure for an alarm device and the alarm device itself.

Abstract

This utility model belongs to the technical field of alarm equipment, and discloses a wiring structure for an alarm device and the alarm device itself. The wiring structure for the alarm device includes a housing and at least two wires. A wiring channel, a first wiring channel, and a second wiring channel are provided on the outer wall of the housing facing the wall. This wiring structure allows the wires to exit from different directions. When the socket is above the alarm device, the wire exits through the first wiring channel; when the socket is below the alarm device, the wire exits through the second wiring channel. Because the wiring hole extends horizontally and the wire extends horizontally, the wire only needs to be bent once, and the bending angle is small, regardless of whether the socket is above or below the alarm device, thus avoiding damage to the wire. At the same time, exiting through the first or second wiring channel also avoids messy wiring and makes the wiring more aesthetically pleasing.

Description

Technical Field

[0001] This utility model relates to the field of alarm equipment technology, and in particular to an outgoing wiring structure and alarm equipment for alarm equipment. Background Technology

[0002] Household gas alarm devices are key devices for protecting the safety of family life and property. They are usually wall-mounted and installed near the ceiling to monitor the concentration of ambient gas in real time and to issue an audible and visual alarm when a dangerous leak is detected.

[0003] Currently, most household gas alarm devices are powered by an external power source. These devices typically have a wiring outlet on the top of the casing, from which the power cord is led out and plugged into a power socket.

[0004] Existing home gas alarm devices have wiring outlets facing a specific direction, meaning the wires can only exit from a fixed location on the device. However, due to varying socket locations in different homes—sometimes above, sometimes below—the wiring needs to be bent multiple times at significant angles if the socket is below the device, increasing the risk of damage. Furthermore, existing home gas alarm devices typically have two or three wires; when the socket is far from the device, the wiring becomes messy and unsightly. Utility Model Content

[0005] The purpose of this invention is to provide a wiring structure for an alarm device and an alarm device in general. This wiring structure allows wires to exit from different directions, preventing continuous large-angle bends in the wires during installation, regardless of whether the socket is above or below the alarm device, and also making the wiring more aesthetically pleasing.

[0036] like Figures 1-4As shown, this embodiment provides a wiring structure for an alarm device, including a housing 1 and at least two wires 2. The housing 1 has an internal cavity. On the outer wall of the housing 1 facing a wall, there are a wiring channel 11, a first wiring channel 12, and a second wiring channel 13. The wiring channel 11 is located at the center of the housing 1. The first wiring channel 12 is located above the wiring channel 11 and extends vertically. The second wiring channel 13 is located below the wiring channel 11 and extends vertically. Both the first and second wiring channels 12 are connected to the wiring channel 11. A horizontally extending wiring hole is provided on the side wall of the wiring channel 11. The first end of the wire 2 is located inside the housing 1, and the second end of the wire 2 extends from the wiring hole to the wiring channel 11. The wire 2 can exit through either the first wiring channel 12 or the second wiring channel 13.

[0037] The wiring structure for the alarm device allows the wire 2 to exit from different directions. When the socket 200 is above the alarm device, the wire 2 exits through the first wiring channel 12; when the socket 200 is below the alarm device, the wire 2 exits through the second wiring channel 13; when sockets 200 are located both above and below the alarm device, the wire 2 can exit partially through the first wiring channel 12 and partially through the second wiring channel 13. Since the exit hole extends horizontally and the wire 2 extends horizontally, the wire 2 only needs to be bent once, and the bending angle is small, regardless of whether the socket 200 is above or below the alarm device, thus avoiding damage to the wire 2. Simultaneously, exiting through the first wiring channel 12 or the second wiring channel 13 also prevents messy wiring of the wire 2, making the wiring more aesthetically pleasing. Specifically, the housing 1 has a cuboid structure. Three wires 2 are provided.

[0038] Optionally, at least two outlet holes are provided, each corresponding to a wire 2. Each wire 2 extends from its corresponding outlet hole, further preventing messy wiring and making the wiring more aesthetically pleasing. Specifically, three outlet holes are provided. The diameter of the outlet holes is the same as the diameter of the wire 2, allowing the wire 2 to fit snugly against the inner wall of the outlet hole and preventing the wire 2 from moving circumferentially.

[0039] Furthermore, some of the cable outlet holes are located on the side wall of the first horizontal end of the cable outlet groove 11, while the other portion are located on the side wall of the second horizontal end of the cable outlet groove 11, which saves installation space. Specifically, one cable outlet hole is located on the side wall of the first horizontal end of the cable outlet groove 11, and the other two cable outlet holes are vertically spaced on the side wall of the second horizontal end of the cable outlet groove 11.

[0040] Optionally, two first wiring troughs 12 and two second wiring troughs 13 are provided, with the two first wiring troughs 12 spaced apart horizontally and the two second wiring troughs 13 spaced apart horizontally. The wire 2 can exit from different first wiring troughs 12 or different second wiring troughs 13, further preventing messy wiring and making the wiring of the wire 2 more aesthetically pleasing. Specifically, the wire 2 extending from the exit hole on the side wall of the exit trough 11 exits from different first wiring troughs 12 or different second wiring troughs 13.

[0041] Optionally, the sidewalls of the cable outlet 11 along the vertical direction are inclined relative to the horizontal direction to reduce the bending angle of the wire 2 and further prevent damage to the wire 2. Specifically, the width of the side of the cable outlet 11 with one cable outlet hole along the vertical direction is smaller than the width of the side of the cable outlet 11 with two cable outlet holes along the vertical direction.

[0042] Optionally, such as Figure 1 , Figure 2 and Figure 5 As shown, the wiring structure for the alarm device also includes a tail clip 3. The tail clip 3 is located on the side of the wiring hole facing the wiring groove 11 and is connected to the housing 1. The tail clip 3 has a through hole, through which the wire 2 passes and extends into the wiring groove 11. By setting the tail clip 3, the wire 2 can be further fixed, improving the anti-pulling function of the wire 2 and preventing the wire 2 from falling off.

[0043] Furthermore, a first engaging portion is provided on the side wall of the cable outlet 11, and a second engaging portion 31 is provided on the tail clip 3. The first engaging portion engages with the second engaging portion 31. This facilitates the installation and removal of the tail clip 3. Specifically, three tail clips 3 are provided, each corresponding to a cable outlet hole. The first engaging portion has a slot, and the second engaging portion 31 is interference-fitted with the slot, applying a certain external force to the tail clip 3 to make it engage within the slot.

[0044] Optionally, such as Figure 1 , Figure 2 and Figure 6 As shown, the outgoing cable structure for the alarm device also includes a baffle 4. The baffle 4 is installed on the housing 1 and blocks the outgoing cable hole, which can prevent the components inside the housing from being exposed and also protect the wire 2. At the same time, the baffle 4 enables the alarm device to meet the national fire protection standard IP30 requirements.

[0045] Specifically, the baffle 4 is a long strip-shaped structure. Two baffles 4 are provided, corresponding to and blocking the cable outlet holes on both sides of the cable outlet groove 11 along the horizontal direction. The baffles 4 can be fixed to the housing 1 by snap-fit ​​or adhesive, which is not limited in this embodiment.

[0046] Optionally, such as Figures 1-4As shown, the housing 1 includes a front housing 14 and a rear housing 15. The front housing 14 is connected to the rear housing 15 and forms a receiving cavity between them. The cable outlet groove 11, the first cable routing groove 12 and the second cable routing groove 13 are all located on the side of the rear housing 15 away from the front housing 14, which facilitates the processing and manufacturing of the housing 1 and the installation and removal of devices located inside the receiving cavity of the housing 1.

[0047] Specifically, the front housing 14 and the rear housing 15 are snapped together. Multiple snaps are provided at intervals on one edge of the middle section of the front housing 14 and the rear housing 15, and a retaining edge is provided on the other edge. The snaps and the retaining edge are interference-fitted to fix the front housing 14 and the rear housing 15.

[0048] like Figures 1-7 As shown, this embodiment also provides an alarm device, including a control board and the aforementioned wiring structure for the alarm device. The control board is installed inside the receiving cavity, and the first end of the wire 2 is electrically connected to the control board. Specifically, the alarm device is a household gas alarm device. The alarm device is fixed to the wall, and according to national standards, the top of the alarm device is approximately 300mm from the ceiling. The alarm device also includes a fixing plate 300, which is circular. One side of the fixing plate 300 is adhered to the wall, and four slots are provided on the fixing plate 300. The rear housing 15 is located on the side of the fixing plate 300 facing away from the wall, and four snap-fit ​​protrusions 16 are provided on the rear housing 15. The snap-fit ​​protrusions 16 correspond one-to-one with the slots and snap into the slots to fix the rear housing 15 to the wall. The rear housing 15 is also provided with four limiting protrusions 17, and the sidewall of the fixing plate 300 can fit against the four limiting protrusions 17 to improve the stability of the snap-fit ​​between the rear housing 15 and the fixing plate 300. The control board is equipped with detection elements and alarm elements. The detection elements and alarm elements are connected in communication. After the detection element detects a specified gas, it transmits a signal to the alarm element, which then issues an audible and visual alarm so that the user can be notified.
