Description

Technical Field

[0001] This utility model relates to the field of curtain wall ventilator technology, and in particular to a handle switch. Background Technology

[0002] A curtain wall ventilator is a ventilation device specifically designed for curtain wall buildings. It features wind and rain protection, noise reduction, and heat insulation, making it a perfect match for curtain walls. Not only does it meet the strength requirements of curtain walls, but its lifespan is also comparable to that of curtain walls. The curtain wall ventilator utilizes the principle of natural ventilation and local pressure differences to achieve air exchange, replacing the traditional method of opening windows for ventilation. It can be manually or electrically opened and closed, and the air volume can be adjusted at any time, effectively improving indoor air quality and ensuring a comfortable and healthy indoor environment.

[0003] However, the manual switches of some existing curtain wall ventilators are all rotary switches. Rotary switches rely on only a small part of the fingers to apply force, resulting in a small force area and obvious finger pain. Furthermore, if the hands are wet or the rotary switch is slippery due to oil from prolonged use, the knob is difficult to turn. Therefore, we propose a lever switch. Utility Model Content

[0004] The purpose of this utility model is to provide a handle switch that can solve the problem of cumbersome operation of some existing curtain wall ventilators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a handle switch, comprising:

[0006] Mounting plate, on which a base is mounted;

[0007] The switching mechanism, mounted on the base, includes a flip cover, connecting parts, and connecting holes. The flip cover is rotatably mounted between the front and rear inner walls of the base. Two sets of connecting parts are integrally formed on the flip cover, and a connecting hole is opened through each set of connecting parts. Under the action of the switching mechanism, the curtain wall ventilator can be directly pulled or pressed to open or close. When opening, the contact area between the finger or palm and the switch is large, making it easy and convenient. When closing, it can be directly pushed back. The whole process will not cause any discomfort to the user's hand. This solves the problem that some existing curtain wall ventilators use knob switches for manual operation. Knob switches rely on only a small part of the fingers to apply force, resulting in a small force area and obvious finger pain. Furthermore, if the hands are wet or the knob switch is slippery due to oil from long-term use, it is difficult to rotate. This improves the practicality of the lever switch.

[0008] The positioning mechanism is located between the base and the flip cover, and is used to assist in positioning when the flip cover is opened and closed.

[0009] Preferably, the positioning mechanism includes a first positioning groove, a second positioning groove, a protrusion, a through groove, and a spring positioning bead. A first positioning groove and a second positioning groove are provided on both the front and rear sides of the flip cover. A set of protrusions is integrally formed on both the front and rear sides of the base. A through groove is provided through each of the two sets of protrusions, and a set of spring positioning beads is fixedly installed in each of the two sets of through grooves. Both sets of spring positioning beads engage with the corresponding second positioning groove. Under the action of the positioning mechanism, the flip cover's switch position can be positioned, making the flip cover's switch position obvious and providing immediate operational feedback through a clear pressing or pulling action. In contrast, the knob requires the user to observe its position or rely on other indicators to determine whether the operation has been successful, ensuring the effectiveness of the lever switch and facilitating its promotion and use.

[0010] Preferably, the spring positioning bead includes a mounting sleeve, a positioning bead, and a spring. A set of mounting sleeves is fixedly installed on the inner wall of each of the two sets of through slots. A set of positioning beads is provided inside each of the two sets of mounting sleeves. A set of springs is fixedly connected between the outer surface of each set of positioning beads and the inner wall of the corresponding mounting sleeve.

[0011] Preferably, a set of notches is provided on the inner walls of both the front and rear sides of the mounting plate, and the two sets of protrusions are engaged in the corresponding notches.

[0012] Preferably, the mounting plate has at least two sets of first mounting holes.

[0013] Preferably, two sets of mounting plates are integrally formed on both sides of the base, and each of the four sets of mounting plates has a second mounting hole that is aligned with the corresponding first mounting hole.

[0014] Preferably, a rubber pad is fixedly installed on the inside of the flip cover near the base, making it more comfortable for the user to flip the cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) This handle switch allows the curtain wall ventilator to be pulled or pressed directly when it is turned on or off via the switching mechanism. When it is turned on, the contact area between the finger or palm and the switch is large, making it easy and convenient. When it is turned off, it can be pushed back directly. The whole process will not cause any discomfort to the user's hand. This solves the problem that some existing curtain wall ventilator manual switches are knob switches. Knob switches rely on only a small part of the fingers to apply force, resulting in a small force area and obvious finger pain. Furthermore, if the hands are wet or the knob switch is slippery due to oil from long-term use, the knob is difficult to rotate. This improves the practicality of the handle switch.

[0017] (2) The handle switch, through the positioning mechanism, can position the switch position of the flip cover. The switch position of the flip cover is obvious, and it provides immediate operation feedback through clear pressing or pulling actions. In contrast, the knob requires the user to observe its position or rely on other indicators to judge whether the operation has been successful. This ensures the effectiveness of the handle switch and is conducive to the promotion and use of the handle switch. Attached Figure Description

Each of the four sets of mounting plates 7 has a second mounting hole 8 that is aligned with the corresponding first mounting hole 6. Through the switching mechanism 3, the curtain wall ventilator can be directly pulled or pressed to open and close. When opening, the contact area between the finger or palm and the ventilator is large, making it easy and convenient. When closing, it can be directly pushed back. The whole process will not cause any discomfort to the user's hand. This solves the problem that some existing curtain wall ventilators use knob switches for manual operation. Knob switches rely on only a small part of the fingers to apply force, resulting in a small force area and obvious finger pain. Furthermore, if the hands are wet or the knob switch is slippery due to prolonged use, it is difficult to rotate. This improves the practicality of the handle switch.

A set of mounting sleeves 451 is fixedly installed on the inner wall of each of the two sets of through slots 44. A set of positioning beads 452 is provided in each of the two sets of mounting sleeves 451. A set of springs 453 is fixedly connected between the outer surface of each set of positioning beads 452 and the inner wall of the corresponding mounting sleeve 451. Through the positioning mechanism 4, the switch position of the flip cover 31 can be positioned. The switch position of the flip cover 31 is obvious, and it provides immediate operation feedback through a clear pressing or pulling action. In contrast, the user needs to observe the position of the knob or rely on other indicators to determine whether the operation has been successful. This ensures the effectiveness of the lever switch and is conducive to the promotion and use of the lever switch.
