Technical Field

The utility model relates to the technical field of shutters, in particular to a transmission mechanism and a shutter with the transmission mechanism.

Background technique

As architectural design has set off a wave of innovation around the world, people have higher and higher requirements for the appearance and performance of buildings. As part of the building's external protective structure (curtain wall), people have also put forward higher and higher requirements for the performance and appearance of manual glass blinds. Blinds are traditional sunshade products. Generally, magnetic force is used to control the blinds in the hollow glass interior. Generally, manual pull ropes or mechanical methods are used to open or close. This product not only saves space, but also achieves the purpose of sunshade. It also has heat preservation and noise prevention functions, and at the same time gives the building and the interior a novel visual experience. Whether in summer or winter, the angle of the blinds can be adjusted to achieve sunshade or lighting and heating.

The transmission mechanism of existing Venetian blinds is not stable when opening and closing. Venetian blinds are used for shading, lighting, heating and improving the privacy of residents. After the blades of the Venetian blinds are closed, due to the poor stability of the transmission mechanism, the wind outside the Venetian blinds can easily blow the blades to rotate, forming an open state, and the privacy of the residents cannot be guaranteed.

Detailed ways

The present invention is described in detail below with reference to the accompanying drawings.

As shown in Figures 1-5, a transmission mechanism 2 includes a blade 3 and a rotating block 34 for installing the blade 3, and also includes a driving member that drives the rotating block 34 to rotate. The driving member includes a first linkage rod 21 and a second linkage rod 22 that are arranged at intervals, and the first linkage rod 21 and the second linkage rod 22 are both connected to the rotating block 34; the driving member includes a driving handle 23 that can be swingably installed on the first linkage rod 21, and a spring piece 27 is movably connected between the driving handle 23 and the second linkage rod 22.

In the initial state, the blade 3 is in the unfolded state. If it needs to be closed, the driving handle 23 is swung. At this time, the spring piece 27 has elastic force to produce deformation and compression, and the first linkage rod 21 and the second linkage rod 22 do not move. When the spring piece 27 is compressed to start to rebound, the first linkage rod 21 and the second linkage rod 22 move relative to each other under the drive of the driving handle 23 and the spring piece 27, so that the rotating block 34 rotates, and the blade 3 installed on the rotating block 34 rotates to achieve closure; the spring piece 27 provides elastic force, and the stability of the blade 3 after closing is better and it is not easy to rotate. The stability after closing and opening is good, and the privacy of the residents can be guaranteed.

The first linkage rod 21 and the second linkage rod 22 are arranged in parallel and spaced apart, and the rotating block 34 is provided with a first connection point 28 movably connected to the first linkage rod 21 and a second connection point 29 movably connected to the second linkage rod 22. The driving handle 23 is swung, and the driving handle 23 swings around the first linkage rod 21. The end of the driving handle 23 will continuously approach or move away from the connection between the second linkage rod 22 and the spring sheet 27. When approaching, the spring sheet 27 will be compressed. After reaching the nearest point, the driving handle 23 will continue to be driven to swing. At this time, the end of the driving handle 23 will move away from the connection between the second linkage rod 22 and the spring sheet 27, so that the first linkage rod 21 and the second linkage rod 22 move relative to each other. Through the movably connected first connection point 28 and second connection point 29, the rotating block 34 rotates accordingly.

Preferably, the first connection point 28 and the second connection point 29 may be rivet structures.

Preferably, the driving handle 23 is provided with a fulcrum groove 24 rotatably connected to the first linkage rod 21 along the way, the first linkage rod 21 is provided with a first connecting rod 25 connected to the fulcrum groove 24, the driving handle 23 is installed on the fulcrum groove 24 through the first connecting rod 25, and the driving handle 23 can swing around the first connecting rod 25; the second linkage rod 22 is provided with a second connecting rod 26 rotatably connected to one end of the spring sheet 27, the spring sheet 27 can swing around the second connecting rod 26, and the other end of the spring sheet 27 is rotatably connected to the end of the driving handle 23. In this embodiment, in the closed state, when the driving handle 23 is driven upward, the spring sheet 27 provides elastic force and stability at the beginning of the drive, and the blade 3 cannot be moved by hand from the outside, which well protects the privacy of the residents. After one-third of the drive, the blade 3 and the driving handle 23 move synchronously, and the rotation of the blade 3 is the same as the opening of the driving handle 23. Similarly, when opening, the effect is the same as closing.

Preferably, the spring piece 27 is formed by processing of 304 stainless steel.

Preferably, the rotating block 34 is provided with a positioning rotor 35 for mounting the blade 3, and the positioning rotor 35 is formed with a clamping groove 36 adapted to the width of the blade 3, so that the blade 3 swings accordingly under the rotation of the positioning rotor 35, realizes rotation, and realizes opening or closing.

Preferably, the blade 3 includes a sheet body 31 and a first clamping plate 32 and a second clamping plate 33 arranged at both ends of the sheet body 31. The first clamping plate 32 and the second clamping plate 33 clamp the sheet body 31. The cross-sectional shapes of the first clamping plate 32 and the second clamping plate 33 are both L-shaped. The first clamping plate 32 surrounds the left and right side walls of the sheet body 31, and the second clamping plate 33 surrounds the ends of the front and rear side walls. The bolt passes through the first clamping plate 32 to install the sheet body 31 in the clamping groove 36 of the positioning rotor 35, thereby realizing the fixed connection between the blade 3 and the positioning rotor 35.

A shutter comprises a frame 1 and a transmission mechanism 2. The frame 1 is provided with a plurality of blades 3 and a positioning rotor 35 and a rotating block 34 connected to the blades 3. A first linkage rod 21 and a second linkage rod 22 are simultaneously movably connected to the plurality of rotating blocks 34. The plurality of blades 3 are mounted on the frame 1 through the positioning rotor 35 and the rotating block 34. Each rotating block 34 is movably connected to the first linkage rod 21 and the second linkage rod 22. Therefore, by swinging the driving handle 23, all the blades 3 can rotate at the same angle at the same time to achieve opening or closing, thereby blocking or opening the gap space of the frame 1.

Preferably, the frame 1 includes a pair of installation side panels 11 arranged at intervals and installation cross panels 12 arranged at the top and bottom of the installation side panels 11. A limit rod 15 is also arranged between the two installation side panels 11. When the blade 3 rotates, the limit rod 15 can resist the blade 3 to prevent the blade 3 from rotating too much when opened and damaging the transmission mechanism 2, thereby effectively protecting the blinds.

The mounting side plate 11 is provided with an activity cavity 13 for the first linkage rod 21 and the second linkage rod 22 to move. Compared with the transmission mechanism 2 of the traditional Venetian blinds, the mounting side plate 11 has better aesthetics and reliability. Moreover, the transmission mechanism 2 is hidden in the aluminum material and is not easily damaged.

The driving handle 23 and the spring piece 27 are installed in the movable cavity 13 of the mounting side plate 11. The mounting side plate 11 is provided with an movable window 14 for the driving handle 23 to swing and move. The movable window 14 is connected to the movable cavity 13. The driving handle 23 can pass through the movable window 14 and is connected to the first linkage rod 21 in the movable cavity 13. The length of the movable window 14 is certain, which can limit the movement stroke of the driving handle 23, that is, the rotation angle of the blade 3 will not be too large, and will not exceed the stroke to cause damage to the blade 3.

In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
