Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft doors, in particular to an anti-theft door with an anti-lock reminder. Background Art

[0002] In daily life, people often forget to lock the anti-theft door, but the current anti-theft doors are not designed with a device that accurately prompts that the door is locked in place. After searching, the prior art (application number: CN201420196705.0) records "a reverse lock reminder for anti-theft doors, including two parallel touch switches, an active buzzer, and a power supply with a power switch. The two parallel touch switches are connected in parallel with the active buzzer and then connected to the power supply with the power switch to form a closed loop. The closed loop is also connected in series with a first current limiting resistor. This design uses two parallel touch switches in parallel with the active buzzer. One of the two parallel touch switches is installed opposite to the key reverse lock tongue of the anti-theft door so that after the reverse lock is in place, the key reverse lock tongue presses the touch switch to connect the circuit, so that the active buzzer is short-circuited and does not emit a buzzer sound; the other is installed opposite to the manual reverse lock tongue of the anti-theft door so that after the reverse lock is in place, the manual reverse lock tongue presses the touch switch to connect the circuit, so that the active buzzer is short-circuited and does not emit a buzzer sound; this serves as a reminder when the anti-theft door is not reverse locked in place. It has the characteristics of simple structure and low cost."

[0003] The anti-theft door in the prior art achieves the anti-lock reminder effect by installing an anti-lock reminder, but the installation of the anti-lock reminder lacks shock-absorbing and buffering effect. During the frequent opening and closing of the door, it is easy to vibrate and damage the internal components. The external buzzer is located outside the door and lacks anti-theft protection effect. Secondly, the lock tongue of the door body is usually made of cylindrical metal. When the door is locked, it is inserted into the lock hole in an instant, and then frequently collides with the touch switch, resulting in a greatly shortened service life of the touch switch.

DETAILED DESCRIPTION

[0022] Reference Figures 1 to 6 As shown, the utility model provides an anti-theft door with a reverse lock reminder, comprising: a door body 1, a door frame 2 and an installation panel 3, wherein the door body 1 is installed in the door frame 2, and the installation panel 3 is installed on the inner side of the door frame 2, the door body 1 comprises an internal main lock tongue 11 and a reverse lock tongue 12, and a lock hole 21 is opened at a position corresponding to the door frame 2, and a buffer block 24 is arranged in the lock hole 21, and a light touch switch 26 is arranged on the inner side of the lock hole 21, an outer buffer pad 31 is fixed between the installation panel 3 and the door frame 2, and an outer installation hole 27 is opened on the outer side of the door frame 2, An inner buffer pad 34 is glued and fixed to the bottom of the outer mounting hole 27, and a buzzer 35 is installed in the outer mounting hole 27. The buzzer 35 is provided with two buzzers located on the inner and outer sides of the door frame 2, and the buzzer 35 located on the inner side of the door frame 2 is installed on the mounting panel 3, and the buzzer 35 located on the outer side of the door frame 2 is electrically connected to the mounting panel 3 through a wire, and a steel mesh 32 is installed on the outer port of the outer mounting hole 27, the buzzer 35 is located on the inner side of the steel mesh 32, and the buzzer 35 is connected to the inner buffer pad 34 through a mounting block 33.

[0023] In this embodiment, the door body 1, the door frame 2 and the installation panel 3 constitute the main structure of the anti-theft door with anti-lock reminder involved in this application, wherein the installation panel 3 involved is the circuit main control board of the anti-lock reminder in the prior art, and the main control board is provided with electrical components including a buzzer 35, a switch, a power supply and an indicator light.

[0024] Specifically, the outer buffer pad 31 is connected to the door frame 2, and the fixing bolts of the mounting panel 3 are inserted into the inner part of the outer buffer pad 31. At the same time, the outer buffer pad 31 is made of rubber material. Similarly, the mounting block 33 is fixedly connected to the inner buffer pad 34, and there is a sliding gap with the outer mounting hole 27.

[0025] As a preferred implementation, the outer cushion 31 and the inner cushion 34 are used to achieve a shockproof protection effect for the mounting panel 3 and the buzzer 35 .

[0026] like Figure 1 and Figure 2 As shown, there are two lock holes 21, which are respectively connected to the main lock tongue 11 and the anti-lock tongue 12, and a positioning sleeve 22 is provided in the lock hole 21. When the door body 1 is in the anti-locked state, the main lock tongue 11 and the anti-lock tongue 12 are both slidably inserted in the positioning sleeve 22, a guide rod 23 is provided in the lock hole 21, and a buffer block 24 is slidably sleeved on the outside of the guide rod 23, and a limiting ring 25 is provided on the outer end of the guide rod 23, and a first spring 231 is provided between the buffer block 24 and the limiting ring 25 and sleeved on the outside of the guide rod 23.

[0027] As a preferred embodiment, the positioning sleeve 22 is provided to enhance the stability of the locking tongue.

[0028] Specifically, the contact of the touch switch 26 protrudes from the ring hole of the limiting ring 25. When the contact is impacted and retracted into the ring hole, the touch switch 26 is triggered.

[0029] like Figure 3 and Figure 4 As shown, a buffer ball 241 with a hemispherical structure is provided at the center of both sides of the buffer block 24, and a sleeve hole is opened near the edge of the buffer block 24, and a damping sleeve 245 is connected to the sleeve hole, the damping sleeve 245 is sleeved on the outside of the guide rod 23, and an inner groove cavity 244 is opened on the outer wall of the damping sleeve 245, and an outer groove cavity 242 is opened on the inner wall of the sleeve hole of the buffer block 24, and a second spring 243 is connected between the inner groove cavity 244 and the outer groove cavity 242.

[0030] Specifically, the buffer ball 241 on the side facing the lock tongue is set to be a rubber sphere with a harder material, while the buffer ball 241 on the other side is set to be a silicone sphere with a softer material, so that when the lock tongue collides, the trigger stroke will not be shortened. When the lock tongue instantly collides with the buffer ball 241, the buffer block 24 is impacted and moves toward the side of the touch switch 26. At this time, it is restricted by the damping sleeve 245 and the first spring 231, so that the movement of the buffer block 24 will not be too fast until the buffer ball 241 made of silicone material contacts the touch switch 26.

[0031] Specifically, the two touch switches 26 are electrically connected, and the buzzer 35 is alarmed through the installation panel 3 before the rear locking, and the buzzer 35 stops the alarm after the rear locking, whether indoors or outdoors.

[0032] When in use, before reverse locking, the two touch switches and the buzzer are normally closed, and the buzzers alarm simultaneously. Only when reverse locking causes the two touch switches to be disconnected, the buzzer stops alarming. At the same time, the buzzer, mounting panel and touch switch are protected, shock-absorbing and soft-collision protected, thus extending their service life.

[0033] The anti-lock reminder anti-theft door of the utility model can effectively solve the problem that the existing anti-lock reminder anti-theft door lacks a protective structure for some components of the anti-lock reminder, which greatly shortens its service life. On the basis of the existing anti-lock reminder anti-theft door technology, the buzzer, the installation panel and the touch switch are protected, shock-absorbed and soft-collision protected, thereby extending the service life.
