Description

Technical Field

[0001] This utility model belongs to the field of alarm technology, and in particular relates to an alarm with a battery leakage prevention structure. Background Technology

[0002] As people become more safety-conscious, various types of alarms are widely used, such as smoke detectors, burglar alarms, and audible and visual alarms. Due to the limited area where alarms are used, and because they are typically battery-powered, if a battery is missing, the alarm will not function properly in the event of an emergency.

[0003] In related technologies, a wireless alarm device that facilitates battery replacement is disclosed. The device includes a wireless alarm with a battery slot and a fixing mechanism. The fixing mechanism is movably mounted on the wireless alarm and communicates with the battery slot. The fixing mechanism is used to fix and replace the battery in the battery slot. In this invention, pressing a slider causes a concave plate to descend, moving an arc plate away from the battery slot. This causes the arc plate and the concave plate to enter a spring groove. Tilting the wireless alarm allows the battery to be emptied, and a new battery is placed into the battery slot through a through-slot. Releasing the slider causes a second spring to return, closing the through-slot with the arc plate and the concave plate. Simultaneously, the return of the first spring causes the arc plate to contact one end of the battery for fixation, achieving convenient battery replacement. A limiting rod through the arc plate prevents the arc plate from detaching.

[0004] However, the above structure still has shortcomings. Although the alarm makes it easy to remove the battery, it cannot detect whether the battery is missing, and the alarm is not easy to install.

[0005] Therefore, it is necessary to provide a new alarm device with a battery leakage prevention structure to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide an alarm with a battery anti-leakage structure that can detect whether the battery is missing and facilitates the installation, disassembly and replacement of the alarm and battery replacement.

[0008] As a further embodiment of this utility model, a mounting circular plate is provided above the alarm body, a connecting column is fixedly installed on the top of the alarm body, two uprights are fixedly installed on the bottom of the mounting circular plate, and a locking block is fixedly installed on each of the two uprights. Two slots, two arc-shaped sliding grooves and two positioning grooves are provided on the connecting column, and the slots, arc-shaped sliding grooves and positioning grooves are all adapted to the locking blocks.

[0009] As a further embodiment of this utility model, a circular groove is provided at the top of the connecting column, a telescopic spring is fixedly installed in the circular groove, a pressure plate is fixedly installed at the top of the telescopic spring, and a pressure column is fixedly installed at the bottom of the mounting circular plate.

[0010] As a further embodiment of this utility model, a return spring is fixedly installed on one side of the trapezoidal block, and one end of the return spring is fixedly connected to the inner wall of the rectangular slide groove.

[0011] As a further embodiment of this utility model, a rectangular groove is provided on the top of the alarm body, a circular through groove is provided on the inner wall of the bottom of the rectangular groove, an internal threaded hole is provided on the top of the trapezoidal block, and the fixing bolt passes through the circular through groove and is threadedly connected to the internal threaded hole.

[0012] As a further embodiment of this utility model, two fixing plates are symmetrically mounted on the mounting circular plate, and each of the two fixing plates is provided with mounting holes.

[0013] Compared with related technologies, the alarm device with a battery leakage prevention structure provided by this utility model has the following advantages:

[0014] This utility model, by setting up a battery slot, electrode contact pieces, electrode springs, battery, rectangular slide, trapezoidal block, battery cover, rectangular plate and fixing bolts, enables the detection of whether a battery is missing from the battery slot, thus preventing the alarm from malfunctioning.

Detailed Implementation

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A three-dimensional structural diagram of an alarm device with a battery leak-proof structure provided by this utility model; Figure 2 A cross-sectional structural diagram of the alarm device with a battery leak-proof structure provided by this utility model; Figure 3 A partial structural diagram of the alarm device with a battery leak-proof structure provided by this utility model; Figure 4 This is a partial structural diagram of the alarm device with a battery leakage prevention structure provided by this utility model. The alarm device with a battery leakage prevention structure includes: an alarm body 1, a battery slot 2 on the top of the alarm body 1, electrode contacts 3 and electrode springs 4 respectively installed on the inner walls of both sides of the battery slot 2, a battery 5 disposed between the electrode contacts 3 and the electrode springs 4, rectangular sliding grooves 6 on both inner walls of the battery slot 2, trapezoidal blocks 7 slidably installed in both rectangular sliding grooves 6, a battery cover 8 disposed in the battery slot 2, rectangular plates 9 fixedly installed on both sides of the battery cover 8, and fixing bolts 10 installed on both rectangular plates 9.

[0024] like Figure 3 and Figure 4 As shown, a mounting circular plate 11 is provided above the alarm body 1, a connecting column 12 is fixedly installed on the top of the alarm body 1, and two uprights 13 are fixedly installed on the bottom of the mounting circular plate 11. Each of the two uprights 13 is fixedly installed with a locking block 14. The connecting column 12 has two slots 15, two arc-shaped sliding grooves 16 and two positioning grooves 17. The slots 15, arc-shaped sliding grooves 16 and positioning grooves 17 are all adapted to the locking blocks 14.

[0025] By setting up the installation circular plate 11, connecting column 12, upright 13, locking block 14, slot 15, arc-shaped slide 16 and positioning slot 17, the alarm body 1 can be quickly disassembled and installed, thereby improving the convenience of inspecting and replacing the battery of the alarm body 1.

[0026] like Figures 2 to 4 As shown, a circular groove 18 is provided on the top of the connecting column 12, a telescopic spring 19 is fixedly installed in the circular groove 18, a pressure plate 20 is fixedly installed on the top of the telescopic spring 19, and a pressure column 21 is fixedly installed on the bottom of the mounting circular plate 11.

[0027] By setting up a circular groove 18, a telescopic spring 19, a pressure plate 20, and a pressure column 21, the alarm body 1 can be rotated so that the locking block 14 is aligned with the positioning groove 17, and then the elastic force of the telescopic spring 19 can cause the locking block 14 to be locked into the positioning groove 17.

[0028] like Figure 2 As shown, a return spring 22 is fixedly installed on one side of the trapezoidal block 7, and one end of the return spring 22 is fixedly connected to the inner wall of the rectangular slide groove 6.

[0029] By setting a reset spring 22, when the battery 5 is missing, the two trapezoidal blocks 7 can be brought closer to each other, causing the circular through groove 24 to be misaligned with the internal threaded hole 25.

[0030] like Figure 2 As shown, a rectangular groove 23 is provided on the top of the alarm body 1, a circular through groove 24 is provided on the bottom inner wall of the rectangular groove 23, an internal threaded hole 25 is provided on the top of the trapezoidal block 7, and the fixing bolt 10 passes through the circular through groove 24 and is threadedly connected to the internal threaded hole 25.

[0031] By setting a rectangular groove 23, a circular through groove 24, and an internal threaded hole 25, the circular through groove 24 can be aligned with the internal threaded hole 25 after the battery 5 is installed, so that the fixing bolt 10 can pass through the circular through groove 24 and be connected to the trapezoidal block 7 through the internal threaded hole 25.

[0032] like Figure 4As shown, two fixing plates 26 are symmetrically installed on the mounting circular plate 11, and each of the two fixing plates 26 has a mounting hole 27.

[0033] By providing a fixing plate 26 and mounting holes 27, it is easy to install the mounting disc 11 on the ceiling, and then connect the alarm body 1 to the mounting disc 11.

[0034] The working principle of the alarm with a battery leakage prevention structure provided by this utility model is as follows:

[0035] First step: When using, install the mounting plate 11 on the ceiling through the fixing plate 26 and mounting hole 27, install the battery 5 in the battery slot 2, and connect the two ends of the battery 5 to the electrode contact 3 and the electrode spring 4 respectively. After installation, the battery 5 will cause the two trapezoidal blocks 7 to move away from each other. At this time, the internal threaded hole 25 is aligned with the circular through slot 24. Then, cover the battery cover 8 and thread the fixing bolt 10 through the circular through slot 24 and connect it to the internal threaded hole 25. If the battery is not installed, the two trapezoidal blocks 7 will move closer to each other under the action of the return spring 22, causing the circular through slot 24 and the internal threaded hole 25 to be misaligned. This will prevent the fixing bolt 10 from connecting to the internal threaded hole 25, making it impossible to fix the battery cover 8. This will remind the installer when the battery is missing.

[0036] Second step: Then, align the pressure column 21 with the circular groove 18 and push the alarm body 1 upwards, thereby compressing the telescopic spring 19. At this time, the locking block 14 is inserted into the arc-shaped slide groove 16 through the slot 15. Then, rotate the alarm body 1 so that the locking block 14 slides in the arc-shaped slide groove 16 to below the positioning groove 17. Release the alarm body 1, and under the action of the elastic force of the telescopic spring 19, the locking block 14 is locked into the positioning groove 17, completing the installation of the alarm body 1.
