[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1 to 4 As shown, the utility model provides a sliding cover type manual alarm button which is convenient for replacing an alarm glass, comprising an upper cover 1, a middle cover 2 and a base 3. Among them, the lower end of the upper cover 1 is an open structure, the upper cover 1 is sleeved on the middle cover 2, the side wall of the upper cover 1 is provided with a clamp assembly 6, the front end of the upper cover 1 is provided with a hollow part, the hollow part is used to expose the alarm glass piece 14, and the interior of the upper cover 1 is provided with a conical clamp 13 made of insulating material; the middle cover 2 is arranged between the upper cover 1 and the base 3, the side wall of the middle cover 2 is provided with a slide rail 7, the slide rail 7 is slidably connected with the clamp assembly 6, the upper part of the middle cover 2 is provided with an alarm contact 12, the conical clamp 13 can be inserted into the alarm contact 12, and the lower front end of the middle cover 2 is provided with a groove, and two fixing holes 11 are respectively provided on the left and right sides of the groove, the groove is used to place the alarm glass piece 14, the fixing hole 11 can be used to fix the middle cover 2 and the base 3 through a fixing piece, and by pressing the alarm glass piece 14, the alarm contact 12 can send an alarm signal; a circuit board electrically connected to the alarm contact 12 is provided on the base 3.

[0036] The utility model provides a sliding cover type manual alarm button which is convenient for replacing the alarm glass. The middle cover 2 and the upper cover 1 are connected by a sliding cover type structure through a slide rail 7 and a clamping component 6 for sliding connection. Therefore, the disassembly and assembly of the upper cover 1 of the manual alarm button is more convenient. The broken alarm glass piece 14 is removed from the groove and a new alarm glass piece 14 is placed in the groove. A conical clamping component 13 is provided inside the upper cover 1. When the upper cover 1 slides upward to the top position relative to the middle cover 2, the conical clamping component 13 can be clamped into the alarm contact 12, thereby preventing maintenance personnel from omitting the step of clamping the insulating material at the position of the alarm contact 12 and preventing the occurrence of false alarms.

[0037] In some embodiments, the clamping component 6 includes a slider 17, a screw 15 and a knob 16. The slider 17 is slidably connected to the slide rail 7. The screw 15 is threadedly connected to the slider 17, and the screw 15 can abut against the bottom of the slide rail 7. The knob 16 is arranged at one end of the screw 15 away from the bottom of the slide rail 7. The slider 17 slides relative to the slide rail 7, so that the upper cover 1 can slide relative to the middle cover 2. When the upper cover 1 slides to a desired position relative to the middle cover 2, the knob 16 is rotated, and the knob 16 drives the screw 15 to rotate. Since the screw 15 is threadedly connected to the slider 17, the screw 15 can extend or retract relative to the slider 17. When the screw 15 extends, the slider 17 can abut against the bottom of the slide rail 7, thereby limiting the slider 17 on the slide rail 7. Exemplarily, the slide rail 7 is a dovetail groove, and the slider 17 is a wedge block that cooperates with the dovetail groove.

[0038] In some embodiments, an alarm indicator light 9 is provided at the top of the middle cover 2, and the alarm indicator light 9 is electrically connected to the circuit board. A through hole corresponding to the alarm indicator light 9 is provided at the top of the upper cover 1. A luminous board 4 is provided at the front end of the upper cover 1, and prompt words are provided on the luminous board 4. The luminous board 4 achieves a conspicuous effect, and when an alarm is required, it is convenient for the operator to find the position of the manual alarm button in time. Under normal conditions, the prompt words help prevent accidental touches. For example, the prompt words can be luminous words of "FIRE".

[0039] In some embodiments, a test lock 8 is provided at the lower right end of the middle cover 2, and the test lock 8 abuts against the lower end of the alarm glass sheet 14. Through the above structure, the alarm glass sheet 14 can be locked to prevent other unrelated personnel from arbitrarily removing the alarm glass sheet 14. When the manual alarm button needs to be tested, the operator inserts the key into the test lock 8, the alarm glass sheet 14 will drop under the action of gravity, and the alarm contact 12 will contact to send an alarm signal.

[0040] In some embodiments, a card slot is provided on the lower left side of the base 3, and the card slot is used to place the telephone jack card 10. A telephone jack indicator 5 is provided on the lower left side of the upper cover 1, which is aligned with the telephone jack card 10. For example, the indicator can be luminous. The lower left end of the middle cover 2 is designed with a missing block aligned with the telephone jack card 10 to avoid interference between the middle cover 2 and the telephone jack card 10.

[0041] The working principle of the sliding cover manual alarm button which is convenient for replacing the alarm glass provided by the utility model is as follows:

[0042] Under normal circumstances, the upper cover 1, the middle cover 2 and the base 3 are closed, the knob 16 tightens the screw 15, the screw 15 extends out of the slider 17 and abuts against the bottom of the slide rail 7, so that the slider 17 is clamped on the slide rail 7; when the alarm glass piece 14 is broken, the maintenance personnel only need to unscrew the knob 16, the screw 15 and the slide rail 7 are loosened, the slider 17 can move freely in the slide rail 7, and the upper cover 1 is slid up relative to the middle cover 2, so that the conical clamp 13 is clamped in the alarm contact 12 to prevent false alarms, and the knob 16 is tightened, the slider 17 is clamped on the slide rail 7, the broken alarm glass piece 14 is completely leaked out, and the alarm glass piece 14 can be replaced; after replacing the alarm glass piece 14, it is only necessary to slide the upper cover 1 relative to the middle cover 2 to the hollow part and align it with the alarm glass piece 14, and then tighten the knob 16.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
