Description

Technical Field

[0001] This utility model relates to the field of windproof door latch technology, and in particular to a windproof door latch. Background Technology

[0002] Sometimes when people go out to put out the trash, pick up a package, or get takeout, they like to leave the door open because the time is short. However, the door may close automatically due to the wind. If you don't have your keys with you, this can cause unnecessary trouble. A windproof door latch is a device that can effectively prevent the door from closing easily after being blown by the wind.

[0003] Windproof door latches are also divided into snap-fit ​​type and magnetic type. Snap-fit ​​windproof door latches consist of a snap block and a snap fastener. However, snap-fit ​​windproof door latches require frequent insertion and removal operations, which can easily lead to damage to the snap fasteners after prolonged use. Since it is difficult to repair or replace the snap fasteners individually after they are damaged, a windproof door latch was designed. Utility Model Content

[0004] This application provides a windproof door latch that can solve the problem that the windproof latch fails when the latch is damaged, and in reality, such matching latches are difficult to repair or be made separately.

[0005] This application provides a windproof door latch, including a base plate, characterized in that a boss is provided on the base plate, an L-shaped plate is connected to the boss, a rotating rod is connected between the L-shaped plate and the boss, a support block one and a support block two are provided between the L-shaped plate and the boss, a protrusion one is provided at both ends of the support block one, and a protrusion two is provided at both ends of the support block two, the protrusion one and the protrusion two are fitted together, the protrusion one and the protrusion two are rotatably connected to the rotating rod, a torsion spring is provided on the rotating rod, and the torsion spring is located between the support block one and the support block two, and a pressure block is installed on the support block one and the support block two.

[0006] Furthermore, a groove is formed on the lower surface of the base plate.

[0007] Furthermore, a waist-shaped groove is formed on the base plate.

[0008] Furthermore, when the pressure block on the first support block and the pressure block on the second support block are in contact with each other, the included angle between the first support block and the second support block is 20°-35°.

[0009] Furthermore, limiting plates are fixedly connected to both sides of the L-shaped plate.

[0010] Furthermore, the L-shaped plate has a slot, the rear sides of the first support block and the second support block are inclined, the first support block and the second support block have a number of slots, and the slots are located at the inclined position. The two ends of the torsion spring are respectively engaged in the slots on the first support block and the second support block.

[0011] In summary, the windproof door latch of this application has the beneficial effect of being adaptable to different latches. Attached Figure Description

[0019] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0020] like Figures 1 to 6As shown, a windproof door latch includes a base plate 1, on which a boss 2 is provided. An L-shaped plate 3 is fixedly connected to the upper surface of the boss 2. The rightmost end of the L-shaped plate 3 is flush with the rightmost end of the boss 2, and the leftmost end of the L-shaped plate 3 is flush with the leftmost end of the boss 2, forming a U-shape with the boss 2. A rotating rod 4 is provided between the L-shaped plate 3 and the boss 2. One end of the rotating rod 4 is rotatably connected to the L-shaped plate 3, and the other end is rotatably connected to the boss 2. A support block 5 and a support are provided between the L-shaped plate 3 and the boss 2. Support block 2 6 has a protrusion 7 at each of the upper and lower ends of support block 1 5, and a protrusion 8 at each of the upper and lower ends of support block 2 6. The protrusion 7 on support block 1 5 fits into the protrusion 8 on support block 2 6, and the protrusion 7 at the bottom of support block 1 5 fits into the protrusion 7 at the bottom of support block 2 6. The protrusions 7 and 8 rotate on the rotating rod 4, and their rotation points are the same. A pressure block 10 is rotatably connected to the front end of support block 1 5 and support block 2 6. A torsion spring 9 is installed on the rotating rod 4, and the torsion spring 9 is located at... Between support block 5 and support block 6, one end of torsion spring 9 is limited to support block 5, and the other end of torsion spring 9 is limited to support block 6. Under the action of torsion spring 9, the pressure blocks 10 on support block 5 and support block 6 are made to fit together. At this time, the included angle between support block 5 and support block 6 is 20°-35°. When the pressure blocks 10 fit together, a naturally formed cavity is formed between support block 5 and support block 6 and protrusions 7 and 8. The pressure block 10 can be roller-shaped or rectangular. When there is a buckle with groove 11, it is generally... It uses a roller type, where the support block 5 and support block 6 are opened by squeezing the middle of the two rollers, and the buckle enters the cavity. The rollers then lock into the groove 11 on the buckle. If a buckle does not have a groove 11, a rectangular pressure block 10 is used. When it is locked in, it is pressed tightly by the torsion spring 9. This makes it difficult to repair or individually manufacture buckles after a set of windproof door buckles is damaged, resulting in individual buckles losing their function and failing to effectively prevent wind. This windproof door can use more buckles and can be used directly as a replacement.

[0021] Furthermore, waist-shaped grooves 12 for adjusting the position are provided on both sides of the base plate 1, and a groove 11 is provided at the bottom of the base plate 1. The groove 11 is located directly below the boss 2. The boss 2 can prevent the windproof door buckle from being installed too tightly, which would prevent the rotating rod 4 from rotating.

[0022] Furthermore, limiting plates 13 are fixedly connected to both sides of the L-shaped plate 3. The limiting plates 13 on both sides can restrict the range of motion of the support block 1 5 and the support block 2 6. The range of motion of the limiting plates 13 can also be increased or decreased by bending the limiting plates 13.

[0023] Furthermore, a slot 15 is provided on the L-shaped plate 3. The rear sides of both support block 1 5 and support block 2 6 are inclined, and the inclinations of support block 1 5 and support block 2 6 are symmetrical. Several slots 14 are provided on the inclined surfaces of support block 1 5 and support block 2 6. One end of the torsion spring 9 is inserted into the slot 14 of support block 1, and the other end of the torsion spring 9 is inserted into the slot 14 of support block 2 6. Tools can be inserted through the slot 15. The torsion spring 9 can be moved by the tool to be inserted into different slots 14 to increase the clamping force between support block 1 5 and support block 2 6. Different sizes of torsion spring 9 can also be replaced.
