Description

Technical Field

[0001] The utility model relates to the field of alarms, and more specifically, to an alarm with a battery anti-misinstallation structure. Background Art

[0002] An alarm is an electronic product that prevents or pre - vents the consequences of an event and reminds or warns us to take certain actions in the form of sound, light, air pressure, etc. It is powered by a battery inside. In the existing technology, during the installation process of the alarm, workers often forget to install the battery inside the alarm body. When it is needed for use, the alarm needs to be disassembled and the battery reinstalled before it can be used. This can easily affect the normal use of the alarm and also increase the labor intensity of workers.

[0003] After retrieval, an existing patent discloses an optoelectronic smoke fire detector alarm with bottom smoke inlet and battery anti - misinstallation, which includes a housing, a circuit board, and a smoke trapping device; the circuit board is installed inside the housing, and the housing is composed of an upper housing and a lower housing spliced together. The smoke trapping device is installed on the installation groove of the lower housing; on both sides above the upper housing, battery installation bins are inclined. At the front and rear ends of the battery installation bin, there are battery negative springs and battery positive elastic pieces respectively. A anti - misinstallation elastic piece is inserted on the side. The battery is installed in the battery installation bin and contacts the anti - misinstallation elastic piece; a battery bin cover is installed above the battery installation bin. The utility model places the smoke trapping device at the bottom to ensure the integrity of the product appearance.

[0004] Existing alarms generally do not have a battery anti - misinstallation structure. For some alarms with an anti - misinstallation structure, the anti - misinstallation structure is very simple and only relies on elastic pieces for restriction. After the battery is installed and enters the use stage, the elastic pieces are pressed by the battery and remain in a stressed state all the time, which is very easy to fail. The failed elastic pieces cannot be reset. Once the elastic pieces fail, the battery anti - misinstallation function of the alarm also fails, and the reliability of the battery anti - misinstallation function of the alarm is not high; at the same time, the cited patent documents do not propose relevant solutions to solve the above problems.

[0005] Therefore, an alarm with a battery anti - misinstallation structure is proposed for the above problems. Summary of the Utility Model

[0006] In order to overcome the above - mentioned defects of the prior art, an embodiment of the utility model provides an alarm with a battery anti - misinstallation structure to solve the problems raised in the above background art.

[0007] To achieve the above object, the present utility model provides the following technical solution: An alarm with a battery anti-misloading structure, including a mounting plate, a mounting seat is installed on the top of the mounting plate, and a protective cover is snap-connected to the top of the mounting seat. An alarm is provided at the middle position of the top of the protective cover, and a control button is provided on one side of the top of the protective cover. An indicator light is provided on the top of the protective cover between the control button and the alarm.

[0015] The technical effects and advantages of the present utility model:

[0016] 1. Compared with the prior art, the alarm with a battery anti-misinstallation structure is provided with an anti-misinstallation component. When the battery is not installed, the pressure plate is not squeezed by the battery, and the sleeve is lifted under the action of the compression spring and is higher than the battery compartment. During assembly, the top of the sleeve is inserted into the limiting groove of the mounting plate, restricting the relative rotation of the mounting seat and the mounting plate and preventing normal installation. When the battery is installed properly, the pressure plate is pressed down, causing the sleeve to be received into the installation groove, and the top is flush with the edge of the battery compartment. As a result, the mounting seat and the mounting plate can rotate relative to each other to achieve normal installation.

[0030] On the basis of Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods. As Figures 1 to 5 shown, see the following description for details:

[0031] As a preferred implementation method, an adhesive groove 14 is arranged at the middle position of the bottom of the mounting plate 1, and six bolt holes 102 are arranged in a circular array on the mounting plate 1 outside the adhesive groove 14. A 3M double-sided adhesive 19 is bonded in the adhesive groove 14; further, the mounting plate 1 can be connected to the wall by bolts or bonded to the wall by the 3M double-sided adhesive 19. The mounting method is diverse and suitable for different types of walls.

[0032] As a preferred implementation method, a second convex edge 103 is arranged at the edge position of the bottom of the mounting plate 1, and the bottom of the second convex edge 103 is flush with the bottom of the 3M double-sided adhesive 19; further, the flush bottom design enables the second convex edge 103 to closely adhere to the wall when bonding with the 3M double-sided adhesive 19, which is more beautiful and can prevent dust from entering and affecting the adhesion of the 3M double-sided adhesive 19.

[0033] As a preferred embodiment, clamping blocks 12 are arranged in a ring-shaped and integral manner at the top of the mounting plate 1, and clamping grooves 11 that cooperate with the clamping blocks 12 are provided at corresponding positions at the bottom of the mounting seat 2. There are three clamping blocks 12 and clamping grooves 11 respectively, and the battery compartment 10 is located between two adjacent clamping grooves 11. Further, the clamping blocks 12 and the clamping grooves 11 are designed such that the mounting plate 1 and the mounting seat 2 can be assembled through the clamping blocks 12 and the clamping grooves 11. During assembly, first stagger the clamping blocks 12 and the clamping grooves 11, and then rotate the mounting seat 2 to screw the clamping blocks 12 into the clamping grooves 11, and the installation can be completed. The assembly is very convenient.

[0034] As a preferred embodiment, a first flange 101 is provided at the edge position of the top of the mounting plate 1, and a flange 201 with an outer diameter matching the inner diameter of the first flange 101 is provided at the edge position of the bottom of the mounting seat 2. Further, during assembly, the outer wall of the flange 201 is attached to the inner wall of the first flange 101. On the one hand, it can make the connection between the mounting plate 1 and the mounting seat 2 tighter and more stable, and on the other hand, it can prevent dust from entering the device from the connection between the two, and the design is more reasonable.

[0035] As a preferred embodiment, the anti-misloading component 8 includes a sleeve 15, a pressing plate 16, a compression spring 17 and a guide post 18. The guide post 18 is threadedly connected to the mounting groove 9. The sleeve 15 is sleeved outside the guide post 18, and a compression spring 17 is installed in the sleeve 15 at the top of the guide post 18. A pressing plate 16 is provided at the bottom of the sleeve 15 close to the battery compartment 10, and the pressing plate 16 and the sleeve 15 are integrally formed by die casting. Further, during use, when the battery is not installed, the pressing plate 16 is not squeezed by the large-capacity battery 7, and the sleeve 15 is lifted under the elastic force of the compression spring 17 and is higher than the battery compartment 10. During assembly, the top of the sleeve 15 is inserted into the limiting groove 13 of the mounting plate 1 to limit the relative rotation of the mounting seat 2 and the mounting plate 1, making it impossible to install normally. When the battery is installed normally, the pressing plate 16 is pressed down, so that the sleeve 15 is received into the mounting groove 9, and its top is flush with the edge of the battery compartment 10, and then the mounting seat 2 and the mounting plate 1 can rotate relative to each other to achieve normal installation.

[0037] The working process of the utility model is as follows:

[0038] First, the mounting plate 1 is connected to the wall by bolts, or bonded to the wall by 3M double-sided tape 19, and then the large-capacity battery 7 is installed into the battery compartment 10. The pressure plate 16 is subjected to the pressure of the large-capacity battery 7 and enters the bottom of the mounting groove 9, so that the sleeve 15 is received in the mounting groove 9, and its top is flush with the edge of the battery compartment 10. During assembly, the mounting seat 2 is first aligned with the mounting plate 1, the block 12 and the slot 11 are staggered, and then the mounting seat 2 is rotated to make the block 12 screw into the slot 11, and the installation can be completed. When the battery is leaked, the pressing plate 16 is not squeezed by the large-capacity battery 7, and the sleeve 15 is lifted up under the elastic force of the compression spring 17, higher than the battery compartment 10. During assembly, the top of the sleeve 15 is inserted into the limiting groove 13 of the mounting plate 1, limiting the relative rotation of the mounting seat 2 and the mounting plate 1, so that it cannot be installed normally. When the device is used for too long and the anti-leakage assembly 8 begins to fail, the anti-leakage assembly 8 can be removed and the compression spring 17 can be replaced.
