Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
as shown in fig. 1, the conventional glass antitheft structure is: one or more wires 302 are embedded within the glass 301, the wires 302 being connected to an alarm circuit. When the glass 301 is broken, the wire 302 is broken, triggering an alarm circuit to activate an alarm. However, in this configuration, particularly for large areas of glass, it is not possible for the wire 302 to extend over the entire sheet of glass, and therefore the triggering of the alarm circuit can be bypassed when a location other than the wire 302, such as the region 303 in fig. 1, is locally damaged. If a plurality of wires are adopted, the process difficulty and the cost are increased undoubtedly.
Example two:
referring to fig. 2, the invention provides a LOW-E glass, which comprises a glass body and a fixing frame 10 arranged on the periphery of the glass body, wherein the glass body comprises a first toughened glass substrate layer 6, a first fiber felt layer 7, a LOW-E film layer 8 and an ultraviolet-proof layer 9 which are arranged from bottom to top in sequence. The first fiber felt layer 7 can prevent broken glass from sputtering when the first toughened glass substrate layer 6 is broken; the low-e film layer 8 has excellent thermal performance and good optical performance, and can reduce radiation; the ultraviolet-proof layer 9 serves to reduce the passage of ultraviolet rays.
In order to realize the anti-theft early warning effect, the glass body further comprises a second toughened glass substrate layer 1 and an isolating layer 4, wherein the second toughened glass substrate layer 1 is arranged below the first toughened glass substrate layer 6 at intervals to form a hollow cavity; the isolation layer 4 is arranged in the hollow cavity and isolates the hollow cavity into a first hollow layer 3 and a second hollow layer 5 from bottom to top. It is worth mentioning that the second fiber felt layer 2 is arranged on the upper side of the second toughened glass substrate layer 1, and the function of the second fiber felt layer is equal to that of the first fiber felt layer 7, which is not repeated.
Referring to fig. 2 and 3, a sliding groove 41 communicating the first hollow layer 3 and the second hollow layer 5 is formed in the isolation layer 4, a sliding block 42 is disposed in the sliding groove 41, the sliding block 42 and the sliding groove 41 are mechanically sealed, and a position above the sliding block 42 in the sliding groove 41 is provided with a limiting portion 43. The air pressure in the first hollow layer 3 is a first air pressure, and the air pressure in the second hollow layer 5 is a second air pressure; the second air pressure < the first air pressure < the standard atmospheric pressure, and the difference between the standard atmospheric pressure and the first air pressure, and the difference between the first air pressure and the second air pressure are sufficient to slide the slider 42. Under the condition that the glass body is intact, the slide block 42 is pressed upwards, so that the slide block 42 is pressed towards the limiting part and is positioned at a fixed position; when the glass is broken, the slider 42 is subjected to atmospheric pressure to move downward, as shown in fig. 4, so that the slider 42 is disengaged from the fixed position.
A circuit board 101 is arranged in the fixed frame 10, a first lead segment 102 is arranged in the isolation layer 4, and a second lead segment 103 is arranged in the sliding block 42; when the slide block is at the fixed position, the circuit board 101, the first conducting wire segment 102 and the second conducting wire segment 103 form a complete alarm circuit, and when the slide block is separated from the fixed position, the alarm circuit is triggered, so that the function of sending out an early warning alarm when glass is damaged is realized.
Referring to fig. 5, in order to implement the alarm function, the alarm circuit includes a relay J1 and a buzzer BELL, the buzzer BELL is disposed on the main circuit of the relay J1, and the first wire segment 102 and the second wire segment 103 are disposed on the control circuit of the relay J1 as lead-out segments; the relay is a normally closed relay. When the glass is intact, controlling the circuit to be closed, enabling the relay J1 to work, and disconnecting the main circuit, wherein the buzzer BELL on the main circuit is not electrified and does not work; on the contrary, when the glass is damaged, the control loop is broken, the relay J1 returns to the normal state and the main loop is closed, the buzzer BELL is electrified to work, and the alarm is given. It is worth mentioning that a communication line can be further arranged on the main loop, and when the glass is damaged, the pre-set terminal can be sent out early warning information.
If the second hollow layer 3 extends over the entire glass body, the first hollow layer 3 and the second hollow layer 5 may be in communication with the atmosphere in a very short time when the glass is instantaneously broken, and the slider 42 may not be detached from the fixed position. In order to avoid this phenomenon, in the present embodiment, the tempered glass 111 is filled in the first hollow layer 3 at a position other than a position right below the slider 42. Through filling, can avoid first hollow layer 3, second hollow layer 5 to great extent to be destroyed simultaneously, improve the sensitivity of alarm.
In order to achieve a sealing spring back after the slider 42 is disengaged from the fixed position, the height of the first hollow layer 3 is smaller than the height of the slider 42.
In order to adjust the air pressure of the first hollow layer 3 and the second hollow layer 5, a first air extraction opening 11 and a second air extraction opening 12 are respectively arranged on the fixing frame 10 corresponding to the first hollow layer 3 and the second hollow layer 5.
Example three:
a manufacturing method of LOW-E glass comprises the following steps:
s1, installing the isolation layer 4 in the fixed frame 10 to enable the first lead segment 102 to be communicated with the control loop of the relay J1;
s2, mounting the slider 42 in the chute 41;
s3, sequentially mounting the other layers of the glass body in the fixing frame 10;
s4, the air pressure in the first hollow layer 3 is adjusted to a first air pressure, and the air pressure in the second hollow layer is adjusted to a second air pressure. The specific adjustment method is as follows:
s41, opening the first air extraction opening and the second air extraction opening to communicate the first hollow layer and the second hollow layer with the atmosphere;
s42, extracting air through the first extraction opening 11 until the air pressure in the first hollow layer 3 is the first air pressure, observing whether the alarm circuit gives an alarm or not, if so, entering S43, otherwise, determining that the alarm circuit is damaged, and taking out for inspection;
s43, closing the first air extraction opening 11, then extracting air through the second air extraction opening 12 until the air pressure in the second hollow layer 5 is the second air pressure, observing whether the alarm circuit gives an alarm again, and closing the second air extraction opening to finish the air pressure adjustment if the alarm is not given.
The air pressure adjustment is independently carried out twice through the first air suction port 11 and the second air suction port 12, and meanwhile, the alarm circuit is observed, so that the self-checking of the alarm circuit can be carried out, and the circuit damage can be stopped in time.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. 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.
