Detailed Description

The utility model will be further illustrated by means of specific embodiments in the following description with reference to the accompanying drawings:

referring to fig. 1, 2 and 5, an embodiment of a window lock mechanism for night reminding of locking a window comprises a common crescent lock hook portion a and a crescent lock catch portion b, which are conventionally arranged on a sliding window, wherein the crescent lock hook portion a can rotate around a connecting shaft on a mounting seat thereof by rotating a handle carried by the crescent lock hook portion a, and a crescent piece of the crescent lock hook portion a can extend into the crescent lock catch portion b, so that locking is realized; in addition, the novel lock comprises a special lock box 1, and a prompt lamp 2, a power supply 3, a protective resistor 4, a photosensitive resistor 5 and a reset switch 6 which are all connected in the lock box 1, wherein the power supply 3, the protective resistor 4, the photosensitive resistor 5 and the reset switch 6 form a first circuit, the power supply 3, the protective resistor 4, the prompt lamp 2 and the reset switch 6 form a second circuit, and the photosensitive resistor 5 and the prompt lamp 2 are connected in parallel; the indicator light 2 is exposed out of the lock box 1, the crescent lock catch part b is connected to the lock box 1, the reset switch 6 is in a normally closed state in a circuit, and the reset switch 6 is provided with a part which extends out of the lock box 1 and can be jacked back by the crescent lock hook part a to cut off the circuit.

In this embodiment, the lock case 1 includes a base 11 and a cover 12, the cover 12 is fastened on the base 11, the indicator light 2 is located on the left side of the cover 12, and the crescent lock catch portion b and the extension of the reset switch 6 are located on the right side of the cover 12. The light-emitting part of the indicator light 2 protrudes out of the surface of the cover body 12, so that the irradiation range of the light source can be enlarged, and the light indication is more obvious. The upper side and the lower side of the cover body 12 are provided with connecting lugs 13 for fixedly connecting the window body, and if the connecting lugs are fixedly connected with the window body through the base 11, the connecting lugs are also an optional fixed connection scheme. The power supply 3, the protective resistor 4 and the photosensitive resistor 5 are all installed and fixed on the base 11 and connected through wires, and the power supply 3 is a battery. The lock box 1 has a light-transmitting portion, and typically, an opening is formed in the lock box 1, and a light-transmitting cover 7 is installed in the opening to allow the internal photo-resistor 5 to sense and detect the external environment. The reset switch 6 comprises a contact 61, a conductive part 62 and an elastic part 63, the tail end of the elastic part 63 is connected inside the lock box 1, the head end is connected with the conductive part 62, the lock box 1 is provided with a mounting and connecting part such as a connecting plate, a connecting seat and the like, the mounting and connecting part is generally fixedly connected with the base 11 (or the cover body 12) or integrally formed, and the elastic part 63 is generally a strip spring; the conductive part 62 is used for connecting and conducting the circuit, and the contact 61 is connected to the conductive part 62 and extends out of the lock case 1. The contact 61 extends towards the crescent locking part b, which is a common L-shaped workpiece in this embodiment, and the contact 61 faces the center of the folded piece part of the crescent locking part b parallel to the right side surface of the cover 12, which serves as a fitting point for the crescent locking hook part a to be stably fastened and abutted.

With reference to fig. 3, 4 and 5, the working principle of the mechanism is as follows: under the daytime environment, even the window is not locked, the warning light can not be lighted, because the photo resistance 5 is under the illumination condition, the resistance is very little, just can make 2 short circuits of warning light and make 2 unable circular telegrams of warning light, so it can not give the user the slightly unnecessary suggestion of not locking the window daytime. Under the night environment, the resistance value of the photoresistor 5 tends to be infinite under the condition of no illumination, so that when the window is unlocked, the circuit where the prompting lamp 2 is located is conducted, and the prompting lamp 2 is lightened to remind a user to lock the window; when a user locks the window, namely the crescent lock hook part a is clamped into the crescent lock catch part b, the outer surface of the crescent lock hook part a presses the contact 61 of the reset switch 6 to the lock box 1 for a certain distance, so that the conductive part 62 is disconnected from the circuit, and the indicator light 2 is immediately turned off to indicate that the window is normally locked.

It will be appreciated by persons skilled in the art that the embodiments of the utility model described above and shown in the drawings are given by way of example only and are not limiting of the utility model. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments, and any variations or modifications may be made to the embodiments of the present invention without departing from the principles.
