Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, 2, 3, 4 and 5, an audible and visual alarm comprises an alarm body, wherein the alarm body comprises a base 1, an alarm unit and a cover body 2, the alarm unit is arranged on the base 1, and the cover body 2 covers the alarm unit and is arranged on the base 1; the outside bottom of the cover body 2 is provided with two connecting blocks 4 in an at least symmetrical manner, correspond on the base 1 the cover body 2 is provided with an annular groove 6, corresponds on the lateral wall of the annular groove 6 the connecting blocks 4 are provided with a longitudinal groove 3 and a transverse groove 7, the transverse groove 7 is arranged at the bottom of the lateral wall of the annular groove, and the longitudinal groove 3 and the transverse groove 7 are communicated to form an L-shaped groove.
During the use, aim at vertical groove 3 with connecting block 4 and press the cover body 2 to 1 direction of base, after connecting block 4 reachd 6 tank bottoms of annular groove, relative base 1 rotatory cover body 2, with connecting block 4 rotatory entering transverse groove 7, can accomplish the connection, swift, convenient.
Preferably, a limiting mechanism is correspondingly arranged on one connecting block 4 and the base 1. Specifically, the limiting mechanism comprises a spring pin 5 arranged at the top of the connecting block 4, and a pin hole 8 and a reset mechanism which are respectively and correspondingly arranged on the base 1, wherein one side of the spring pin 5 facing the transverse groove 7 is an inclined surface; the reset mechanism comprises a reset button 9 and a reset through hole, the reset through hole and the pin hole 8 are coaxially arranged, and the inner diameter of the reset through hole is larger than that of the pin hole 8; the top of the reset through hole is communicated with the top of the base 1, the bottom of the reset through hole is communicated with the top of the pin hole 8, and the bottom of the pin hole 8 is communicated with the top of the transverse groove 7; the reset button 9 comprises a press block and a reset column arranged at the bottom of the press block, the press block is slidably arranged in the reset through hole through a spring, and the reset column is slidably inserted into the upper part of the pin hole 8. In practice, the top of the connecting block 4 is provided with a groove, the spring pin 5 is arranged in the groove, and the upper part of the spring pin 5 protrudes out of the top of the connecting block 4. During the use, after pressing connecting block 4 into longitudinal groove 3, when the cover body 2 was rotated, the bottom of the cell wall that longitudinal groove 3 was close to transverse groove 7 one side was through inclined plane extrusion spring catch 5, with connecting block 4 precession transverse groove 7 back, the upper portion of spring catch 5 gets into in the pinhole 8. At the moment, the pressing block is positioned in the reset through hole, the upper part of the reset column is positioned in the reset through hole, the lower part of the reset column is positioned at the upper part of the pin hole 8, the upper part of the spring pin 5 is positioned at the lower part of the pin hole 8, and due to the pin insertion effect of the spring pin 5, the connecting block 4 cannot be screwed out of the transverse groove 7, namely, the cover body 2 cannot move relative to the base 1, so that the firm connection between the cover body 2 and the base 1 is ensured. In practice, when the spring pin 5 enters the pin hole 8 and is restored to the free state from the extrusion state, a click sound is generated, and the operation personnel can be reminded of the position. During the dismantlement, press reset button 9, reset the post and extrude 5 tops of spring catch downwards, spring catch 5 shrink back, can the counter rotation cover body 2, accomplish the dismantlement.
In practice, there are four connecting blocks 4, and the width of one of the connecting blocks 4 is greater than the width of the other connecting blocks 4, and the spring pin 5 is disposed on the connecting block 4 with the greater width. The connecting block 4 with the spring pin 5 has a larger width by widening the width of the corresponding longitudinal groove 3, so that the identification degree during assembly is convenient to improve, and the assembly efficiency is convenient to further improve.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
