Description

Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to an electrical fire detector. Background Art

[0002] Electrical fire monitoring detectors prevent electrical fires by monitoring and managing fire hazard parameters such as residual current, wire temperature, overcurrent, and overvoltage in the distribution circuit. They also enable real-time monitoring of multiple power parameters and provide data for energy consumption management.

[0003] The existing detector installation process is cumbersome. Existing electrical fire detectors typically use screws or rotating snap-on mounting, which can be cumbersome to install and remove. This approach hinders rapid installation. Therefore, a fast-installation electrical fire detector is needed to improve installation efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides an electrical fire detector, which has the advantages of quick installation and easy disassembly, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: an electrical fire detector, comprising a detector, wherein an operating surface is provided on one side of the detector, a magnetic strip A is fixedly installed on the left side, the right side and the middle of the back of the detector, a display screen is provided in the middle of one side of the operating surface, one side of the operating surface is located above the display screen and an indicator light is provided in a linear array, one side of the operating surface is located obliquely above the indicator light and a sound expansion hole is provided, one side of the operating surface is located below the display screen and an operating button is provided in a linear array, an outer ring of the detector is slidably sleeved with an installation box, an inner wall of the installation box is fixedly installed with a magnetic strip B at a position corresponding to the position of the magnetic strip A, the magnetic strip B and the magnetic strip A are attracted to each other by opposite poles, limiting grooves are provided on both sides of the opening of the installation box, and inserts are slidably installed inside the limiting grooves.

[0006] According to the above structural setting, magnetic strips A and B are set to ensure that when the detector is located close to the installation box, magnetic strips A and B attract each other, which is convenient for the user to align. When the detector is pushed into the installation box, it is easier to install with the help of magnetic strips A and B.

[0007] Preferably, card slots are symmetrically opened on both sides of the interior of the detector, and the card slots are connected to the limit slots. The card slots are located on both sides of the detector and are opened with the magnetic strip A as the symmetry axis. Clips are movably installed on both walls of the card slot. The overall shape of the clips is arc-shaped, and the clips are deformable. The surfaces of adjacent clips are silicone surfaces. A spring A is fixedly connected between the outer wall of the clip and the inner wall of the card slot, and the spring A is fixedly connected to the middle part of the arc of the clip.

[0008] According to the above structural setting, the clips are squeezed by the elastic force of spring A, and the clips on both sides completely block the card slot. Since the clips can be deformed after being pressed and squeezed, when the latch piece enters the card slot, the clips are squeezed, causing the spring A to contract under force. When the latch piece touches the inner wall of the card slot, the clips on both sides of the latch piece will be tightly squeezed on both sides of the latch piece, limiting the position of the latch piece.

[0009] Preferably, a handle is provided on one side of the insert, and a latch piece is symmetrically provided on the other side of the insert with the magnetic strip B as the axis of symmetry. The latch piece is adapted to the card slot, and the thickness of the insert is thicker than that of the latch piece.

[0010] According to the above structural arrangement, when the compressed gap between the clips is large enough for the latch piece to pass through, the latch piece enters the slot and contacts the inner wall of the slot. At this time, the clip is no longer subjected to increased squeezing, and the device is then kept squeezed on both sides of the latch piece. The squeezing force and friction force of the clip on the latch piece fix the position of the latch piece inside the slot without being affected by external forces.

[0011] Preferably, a spring groove is provided on the inner wall of the limiting groove of the installation box, and a spring B is fixedly connected between the bottom wall of the spring groove and the inserting piece.

[0012] According to the above structure, when the latch piece enters the slot to fix the position between the detector and the installation box, the tension of the spring B will assist the latch piece to enter the slot.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The electrical fire detector can be quickly installed by setting up the detector, magnetic strip A, installation box and other structures. When the magnetic strip A and magnetic strip B are close to the installation box, the magnetic strip A and magnetic strip B attract each other, which is convenient for the user to align. When the detector is pushed into the installation box, the magnetic strip A and magnetic strip B are used to facilitate installation, thereby facilitating installation.

[0015] 2. The electrical fire detector is easy to repair and disassemble by providing a clip, an installation box, an insert and other structures. When disassembling the structure, the insert is pulled to slide outward to release the card slot from the squeezing of the clips on both sides, and the detector is pulled to the position inside the installation box to remove the detector from the installation box. The disassembled detector can be repaired or replaced with a new detector and reinstalled inside the installation box, thereby facilitating repair and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 5, an electrical fire detector includes a detector 1, an operating surface 11 is provided on one side of the detector 1, and magnetic strips A12 are fixedly installed on the left, right and rear middle parts of the detector 1, a display screen 13 is provided in the middle of one side of the operating surface 11, one side of the operating surface 11 is located above the display screen 13 and an indicator light 14 is provided in a linear array on one side, a sound amplification hole 15 is provided on one side of the operating surface 11 and obliquely above the indicator light 14, and an operating button 16 is provided in a linear array on one side of the operating surface 11 below the display screen 13, the outer ring of the detector 1 is slidably sleeved with an installation box 2, and a magnetic strip B21 is fixedly installed on the inner wall of the installation box 2 at the position corresponding to the position of the magnetic strip A12, and the magnetic strip B21 and the magnetic strip A12 are attracted to each other by opposite poles, and limiting grooves 22 are provided on both sides of the opening of the installation box 2, and a plug 3 is slidably installed inside the limiting groove 22.

[0025] The device sets magnetic strips A12 and B21 to ensure that when the detector 1 is located close to the installation box 2, the magnetic strips A12 and B21 attract each other, making it easier for the user to align the detector 1. When the detector 1 is pushed into the installation box 2, the magnetic strips A12 and B21 are used to facilitate installation.

[0026] See also Figure 1-Figure 5 The detector 1 has symmetrical slots 17 on both sides of the interior, which are connected to the limit slots 22. The slots 17 are located on both sides of the detector 1 with the magnetic strip A12 as the axis of symmetry. Clips 18 are movably installed on both walls of the slot 17. The overall shape of the clip 18 is arc-shaped, and the clip 18 is deformable. The surfaces of adjacent clips 18 are silicone surfaces with high friction. A spring A19 is fixedly connected between the outer wall of the clip 18 and the inner wall of the slot 17, and the spring A19 is fixedly connected to the middle part of the arc of the clip 18.

[0027] Due to the elastic force of the spring A19, the clips 18 on both sides completely block the slot 17. Since the clips 18 can be deformed after being pressed and squeezed, when the latch piece 32 enters the slot 17, the clips 18 are squeezed, causing the spring A19 to contract under force. When the latch piece 32 touches the inner wall of the slot 17, the clips 18 on both sides of the latch piece 32 will be tightly squeezed on both sides of the latch piece 32, limiting the position of the latch piece 32.

[0028] See also Figures 1-6 A handle 31 is provided on one side of the insert 3 to facilitate the user to pull the insert 3. A latch piece 32 is symmetrically provided on the other side of the insert 3 with the magnetic strip B21 as the symmetry axis. The latch piece 32 is adapted to the card slot 17. The thickness of the insert 3 is thicker than the thickness of the latch piece 32, thereby realizing the limiting effect.

[0029] When the insert 3 is ready to be inserted into the slot 17 to limit the position of the detector 1, the latch piece 32 will first squeeze the clip 18 to increase the arc angle of the clip 18, and then the clip 18 squeezes the spring A19 to squeeze the clip 18 toward a horizontal state. When the compressed gap between the clips 18 is sufficient for the latch piece 32 to pass through, the latch piece 32 enters the slot 17 and contacts the inner wall of the slot 17. At this time, the clip 18 is no longer subjected to increased squeezing, and then this device is kept squeezed on both sides of the latch piece 32. The squeezing force and friction force of the clip 18 on the latch piece 32 fix the position of the latch piece 32 inside the slot 17 without being affected by external forces.

[0030] See also Figures 1-6 A spring groove is provided on the inner wall of the limiting groove 22 of the mounting box 2, and a spring B33 is fixedly connected between the bottom wall of the spring groove and the insert 3 to limit the lateral movement distance of the insert 3, so that the latch piece 32 can enter the interior of the card slot 17 more easily.

[0031] When the latch piece 32 enters the slot 17 to fix the position between the detector 1 and the installation box 2, the tension of the spring B33 will assist the latch piece 32 to enter the slot 17. At the same time, due to the tension of the spring B33, the latch piece 32 remains in the slot 17 without being affected by external forces.

[0032] Working principle: When assembling this structure, first fix the installation box 2 inside the wall so that the plug-in piece 3 is exposed outside the wall, align the magnetic strip A12 position of the detector 1 with the magnetic strip B21 position, and slide the detector 1 into the interior of the installation box 2. Due to the magnetic attraction of the magnetic strip A12 and the magnetic strip B21, the detector 1 and the installation box 2 become better aligned and easier to install. Pull the plug-in piece 3 outward to make the detector 1 completely enter the interior of the installation box 2. Release the hand that pulls the plug-in piece 3, and the spring B33 drives the plug-in piece 3 to move inward, so that the latch piece 32 enters the interior of the slot 17. When the latch piece 32 enters the interior of the slot 17, it squeezes the clips 18 on both sides, causing the clip 18 to deform and causing the spring A19 to be compressed. When the latch piece 32 contacts the interior of the slot 17, the clips 18 on both sides press against the two sides of the latch piece 32, squeezing the latch piece 32 into the interior of the slot 17.

[0033] When disassembling the structure, pull the insert 3 to slide outward to release the card slot 17 from the squeezing of the clips 18 on both sides, pull the detector 1 to the position inside the installation box 2, and remove the detector 1 from the installation box 2. Repair the disassembled detector 1 or replace it with a new one and reinstall it inside the installation box 2, so as to facilitate maintenance and disassembly.
