In one embodiment, the present application provides a sliding door lock comprising a first snap assembly 1, a second snap assembly 2, and a first pin 3;

the first clamping component 1 is L-shaped, and the first clamping component 1 is connected with the door frame 4;

the first contact pin 3 is elastically connected with the door frame 4 in the horizontal direction through a first elastic part 5;

the second clamping component 2 is elastically connected with the sliding door 6 through a second elastic part 7 in the vertical direction;

the first clamping component 1 and the second clamping component 2 are arranged oppositely in the horizontal direction, when the sliding door lock is locked, the first clamping component 1 and the second clamping component 2 are clamped in the horizontal direction, and therefore the sliding door 6 is prevented from moving in the direction away from the door frame 4;

the first opposite surface of the second clamping component 2 is an inclined surface, and the first opposite surface refers to the side surface closest to the first clamping component 1 in all the side surfaces of the second clamping component 2 when the sliding door lock is unlocked;

the first opposite surface is provided with a first slot 8;

the first opposite surface is covered with a sliding sheet 9, and the sliding sheet 9 is used for covering the first slot 8;

the first pin 3 and the first slot 8 are in the same position in the vertical direction;

the first elastic part 5 or the first pin 3 is made of a first temperature-sensitive material, so that the first elastic part 5 or the first pin 3 shortens at a first temperature and elongates at a second temperature, wherein the first temperature is lower than the second temperature;

the second elastic component 7 or the second clamping component 2 is made of a second temperature-sensitive material, so that the second elastic component 7 or the second clamping component 2 extends at a first temperature or a second temperature and shortens at a third temperature, wherein the third temperature is higher than the second temperature.

Referring to fig. 2, fig. 2 is a schematic view of a sliding door lock of the present application, the sliding door lock includes a first clamping component 1, a second clamping component 2 and a first pin 3; the first clamping component 1 is in an L shape, and when the sliding door is locked, the first clamping component 1 is clamped with the second clamping component 2 through the L shape, so that the sliding door 6 is prevented from moving in the direction away from the door frame 4. The first engaging member 1 is connected to the door frame 4, which means that the relative position of the first engaging member 1 and the door frame 4 is maintained. The first pin 3 is elastically connected with the doorframe 4 through the first elastic component 5 in the horizontal direction, which means that the position of the first pin 3 relative to the doorframe 4 can be changed with external force. The second clamping component 2 is elastically connected with the sliding door 6 through the second elastic part 7 in the vertical direction, which means that the position of the second clamping component 2 relative to the sliding door 6 can be changed along with external force. The first elastic member 5 and the second elastic member 7 are, for example, springs. The first opposite surface of the second clamping component 2 is an inclined surface, so that in the locking process, namely the process that the second clamping component 2 approaches the first clamping component 1, the position of the second clamping component 2 in the vertical direction can be lowered, and the second clamping component finally bypasses the first clamping component 1 to form a clamping state. Further, the length of the first elastic part 5 and the first pin 3, which can stretch in the horizontal direction, is greater than the depth of the first slot 8.

The first opposite surface is provided with a first slot 8 for accommodating the first pin 3 in an up-lock state, so that the second clamping component 2 is fixed in the vertical direction. At this time, the second engaging member 2 is engaged with the first engaging member 1 in the horizontal direction and fixed by the first pin 3 in the vertical direction, and thus is locked at a position in a three-dimensional space, and thus cannot move, so that the sliding door 6 is locked. It should be noted that, in the sliding door lock of the conventional art, the door lock can be opened by applying a force in the vertical direction to the second engaging member 2 through a door switch or the like, but the present application does not (because of the existence of the first pin 3).

The first opposite surface is covered with a sliding sheet 9, and the sliding sheet 9 is used for covering the first slot 8. During locking, the slide 9 is caught by the first pin 3, see fig. 4, so that the first socket 8 is exposed and the first pin 3 can be inserted into the first socket 8. Besides, in the present application, said slide 9 has other uses, which will be described in detail below.

The conventional sliding door lock is designed to open the door by using mechanical force (manual force) at one side having a door switch, but not at the other side having no door switch. The application utilizes the characteristics of the temperature-sensitive material to realize that the door can be opened on the other side without the door switch. Specifically, the method comprises the following steps:

the first elastic part 5 or the first pin 3 is made of a first temperature-sensitive material, so that the first elastic part 5 or the first pin 3 shortens at a first temperature and elongates at a second temperature, wherein the first temperature is lower than the second temperature. If the sliding door lock of this application will be opened, then need earlier extract first contact pin 3 from first slot 8, reduce second block subassembly 2 position on the direction of solidly again. In order to achieve the purpose of pulling out the first pin 3 from the first slot 8, the first elastic component 5 or the first pin 3 is made of a first temperature-sensitive material, and only the ambient temperature of the sliding door lock needs to be regulated and controlled to be directly reduced to a first temperature or lower, so that the first elastic component 5 or the first pin 3 can be shortened, the first pin 3 is pulled out from the first slot 8, and the unlocking first step is completed.

Note that at this time, the sliding piece 9 will slide upwards to cover the first slot 8 (because the first pin 3 is separated from the first slot 8 by a certain distance and will not catch the sliding piece 9 any more, so the sliding piece 9 will slide upwards to the original state to cover the first slot 8).

The second elastic component 7 or the second clamping component 2 is made of a second temperature-sensitive material, so that the second elastic component 7 or the second clamping component 2 extends at a first temperature or a second temperature and shortens at a third temperature, wherein the third temperature is higher than the second temperature. To achieve the purpose of lowering the position of the second engaging member 2 in the vertical direction, it is only necessary to raise the ambient temperature of the sliding door lock to a third temperature or higher, so that the second elastic member 7 or the second engaging member 2 will be shortened, and the position in the vertical direction will be lowered until there is no intersection with the first engaging member 1 in the horizontal direction. The second engaging member 2 can move in the horizontal direction, so as to achieve the purpose of unlocking.

It should be noted that without the design of the sliding piece 9, when the ambient temperature rises again, the first pin 3 will tend to return to its original length, and thus will be inserted into the first slot 8 again, thereby locking the second engaging component 2 again. Through the design of the sliding piece 9, the first pin 3 is stopped by the sliding piece 9 and cannot be inserted into the first slot 8 again, so that the second clamping component 2 cannot be locked again in the vertical direction, and the unlocking process of the second clamping component 2 can be continued.

The first temperature-sensitive material and the second temperature-sensitive material can be any feasible material, such as a memory alloy material, for example, a copper-zinc-aluminum memory alloy, a NiTi memory alloy, and the like. The phase change point of the copper-zinc-aluminum memory alloy can be adjusted within the range of-100 ℃ to 300 ℃, so that the phase change point can be set near room temperature by adjusting the component proportion. The transformation point of the NiTi memory alloy can be finely adjusted to 30-50 degrees. Specifically, the phase transition point of the first temperature sensitive material is lower than room temperature (for example, 25 degrees), and the phase transition point of the second temperature sensitive material is higher than room temperature. Then, by means of processing, the length of the first elastic member 5 or the first pin 3 at room temperature (which can be regarded as the second temperature) is longer, and the length at the phase transition point (i.e. the first temperature) is shorter, so that the lengths at different temperatures are memorized. In contrast to the first temperature-sensitive material, the second temperature-sensitive material is processed to make the length of the second elastic member 7 or the second engaging member 2 at room temperature (which may be regarded as the second temperature) shorter and the length at the phase transition point (i.e. the third temperature) longer, so as to memorize the lengths at different temperatures. Wherein the first temperature is for example 10-23 degrees, for example 15 degrees. The second temperature is for example 15-35 degrees, for example 25 degrees. The third temperature is, for example, 20-40 degrees, for example 30 degrees. All the above degrees refer to degrees centigrade.

Further, the first contact pin 3 and the first temperature-sensitive material are arranged, and the operation of mistakenly opening the door can be prevented. That is, if there is not first contact pin 3, first temperature sensitive material, then can realize opening the door through the intensification, but under the high temperature environment in summer, the push-and-pull door lock is in the state of opening the door forever very probably to cause the lock inefficacy. And this application is through a contact pin, the setting of first temperature sensitive material, indulges the messenger in summer, because first contact pin 3 still inserts in first slot 8, consequently the push-and-pull door lock still is in the state of locking, need cool down then heat up again, just can realize the operation of unblanking.

In order to make the sliding door lock of the present application clearer, the locking process of the sliding door lock is shown as shown in fig. 3 to 5. That is, the sliding door 6 is close to before the door frame 4, and there is the contact second block subassembly 2 and first block subassembly 1, because the existence on inclined plane, second block subassembly 2 descends in vertical direction, until bypassing first block subassembly 1, when bypassing first block subassembly 1 after, second block subassembly 2 rises, and gleitbretter 9 is blocked by first contact pin 3, therefore gleitbretter 9 is fixed in first contact pin 3 position, second block subassembly 2 rises completely after, first contact pin 3 because with first slot 8 position is the same, consequently inserts first slot 8 to the sliding door lock is locked and is accomplished.

Therefore, through the design, this application has realized utilizing temperature control, need not mechanical external force, has accomplished under the prerequisite that need not to contact the door switch, opens sliding door lock. Can be applicable to by unexpected people etc. of locking on the balcony (the usable instrument that can control the air conditioner of people on the balcony, for example air conditioner remote controller, or install the cell-phone that can control the APP of air conditioner and come the controlled temperature, and then realize opening the door).

Further, a door switch is connected to the second engaging member 2, the door switch is disposed only on one side of the sliding door 6, the door switch is configured to adjust the position of the second engaging member 2 in the vertical direction by a mechanical force, and the door switch is configured to adjust the position of the first engaging member 1 in the horizontal direction by a mechanical force. Thereby the push-and-pull door lock of this application can also be opened through the door switch. The specific starting process is as follows: firstly, the position of the first clamping component 1 is adjusted towards the direction of the door frame 4 by using a door switch, and then the position of the second clamping component 2 is adjusted towards the direction of the geocentric, so that the lock of the sliding door is opened.

Further, the first temperature-sensitive material is a copper-zinc-aluminum memory alloy, and the second temperature-sensitive material is a nickel-titanium memory alloy. The phase transformation point of the copper-zinc-aluminum memory alloy can be adjusted within the range of-100 ℃ to 300 ℃, so that the phase transformation point can be set near room temperature by adjusting the component ratio, for example, the phase transformation point is finely adjusted to 10 to 30 ℃. The transformation point of the NiTi memory alloy can be finely adjusted to 30-50 degrees. Therefore, the first temperature-sensitive material is made of copper-zinc-aluminum memory alloy, and the second temperature-sensitive material is made of nickel-titanium memory alloy, so that the first elastic component 5 or the first contact pin 3 made of the first temperature-sensitive material is subjected to phase change at a lower temperature, and the length in the horizontal direction is changed (shortened during phase change); so that the second elastic member 7 or the second engaging member 2 made of the second temperature sensitive material is phase-changed at a higher temperature to thereby change the length in the vertical direction (the phase-change time is lengthened). Wherein the phase change shortens and lengthens depending on the processing procedure, i.e. a length is memorized during the phase change, and then the temperature is adjusted and then the processing is performed (for example, at room temperature, so as to shorten or lengthen), thereby realizing that the first elastic component 5 or the first pin 3 shortens at a lower temperature, and the second elastic component 7 or the second clamping component 2 shortens at a higher temperature.

Furthermore, the free end of the first pin 3 is connected with a detachable auxiliary head, the upper end surface of the auxiliary head in the vertical direction is an inclined surface, and the position of the inclined surface of the auxiliary head is lower as the inclined surface is farther from the door frame 4. As shown in fig. 6. Due to the existence of the auxiliary head, when the door switch needs to be arranged, the door switch can be independent of the first contact pin 3, namely the first contact pin 3 is pulled out, the second clamping component 2 is shortened in the vertical direction, the inclined surface of the auxiliary head is pressed by the second clamping component 2 and decomposed into horizontal force towards the door frame 4 due to the existence of the inclined surface, and therefore the first plug is pulled out of the slot.

Further, a second opposite surface of the first clamping component 1 is coated with a first magnetic coating, and a second opposite surface of the second clamping component 2 is coated with a second magnetic coating; the second opposite surface of the first clamping component 1 refers to the side surface which is farthest away from the second clamping component 2 in all the side surfaces of the first clamping component 1 when the sliding door lock is unlocked; the second opposite surface of the second clamping component 2 refers to the side surface which is farthest away from the first clamping component 1 in all the side surfaces of the second clamping component 2 when the sliding door lock is unlocked; the magnetic properties of the first magnetic coating are opposite to the magnetic properties of the second magnetic coating. Therefore, when the locking mechanism is locked, the second opposite surface of the first clamping component 1 and the second opposite surface of the second clamping component 2 are not tightly attached to each other, so that the friction is reduced, and the service life is prolonged.

Furthermore, the sliding door lock comprises a second contact pin, and a second slot is further formed in the first opposite surface; the second contact pin is elastically connected with the doorframe 4 through a third elastic component in the horizontal direction; the second pin and the second slot are in the same position in the vertical direction; the second slot is lower than the first slot 8 in the vertical direction; the third elastic component is made of the second temperature-sensitive material.

The purpose of the second slot is explained with emphasis here. After the second slot is added, the sliding door lock can be changed specially, namely, the sliding door lock is opened, namely, the sliding door lock is not cooled firstly and then heated, and then the sliding door lock is heated, cooled and then heated. And the second slot is lower than the first slot 8 in the vertical direction, so that when the temperature is raised first, the second contact pin is pulled out from the second slot first, the slide sheet 9 covers the second slot first, then the temperature is lowered, the first contact pin 3 is pulled out, the slide sheet 9 covers the first slot 8 again, the temperature is raised again, and the second clamping component 2 is lowered, so that the lock is unlocked. This design prevents malfunction in winter. For example, if the temperature is low in winter and the air conditioner is not turned on in the initial state, the first pin 3 is pulled out of the first slot 8; when the air conditioner is turned on and the temperature is too high, the second clamping component 2 is caused to descend, and the mistaken unlocking is caused. The arrangement of the present application is not so that the temperature is low in winter, the air conditioner is not turned on in the initial state, the first pin 3 is pulled out of the first slot 8, but the second pin located at the lower position is still pulled out of the second slot, so that the sliding sheet 9 does not cover the first slot 8, and the problem of mistaken unlocking is not caused.

In one embodiment, the present application provides a method for unlocking a sliding door lock, wherein the sliding door lock adopts the sliding door lock described in any one of the preceding claims, and an initial state of the sliding door lock is a locked state, including:

controlling an ambient temperature controller by using a remote controller to lower the ambient temperature of the sliding door 6 to the first temperature or lower, so that the first pin 3 is separated from the first slot 8, and then the sliding sheet 9 covers the first slot 8;

and then, the remote controller is used for controlling the ambient temperature controller to enable the ambient temperature to rise to the third temperature or be higher than the third temperature, so that the second clamping component 2 is shortened in the vertical direction, the second clamping component 2 and the first clamping component 1 are staggered in the vertical direction to be separated from the clamping state, and the lock of the sliding door is opened.

The remote controller can be a wireless remote controller, such as a wireless air conditioner remote controller, or a mobile phone realizing wireless remote control through APP, or a wired control panel (for controlling an air conditioner) physically fixed at the door side, and the like. The ambient temperature controller is, for example, an air conditioner. At this moment, the door opening process of the sliding door lock is that the temperature is firstly reduced to a first temperature or lower, and then the temperature is increased to a third temperature or higher, so that the sliding door lock is opened.

According to the unlocking method of the sliding door lock, the unlocking operation can be completed without touching the door switch, namely the unlocking operation can be completed only by adopting temperature control, the daily life is convenient, and the potential safety hazard is favorably reduced.
