Description

Technical Field

[0001] This utility model relates to the technical field of membrane tensioning devices, specifically an F-CLEAN membrane tensioning device. Background Technology

[0002] ETFE film is made from ETFE resin produced by Asahi Glass. It possesses many outstanding properties such as high light transmittance, high strength, and long lifespan, and is widely used in many industries, including greenhouses. Existing film installation methods require the film to be installed in a pressing groove. However, this method can cause the film to loosen under high temperatures, especially F-Clean film used on the roof of Venlo greenhouses, where it expands and loosens due to heat, producing loud noises in windy conditions and potentially causing damage. Furthermore, existing methods of additionally pressing the film using fixing straps require burying the straps in the ground, which is cumbersome. Therefore, we have proposed an F-CLEAN film tensioning device to solve these problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment of this utility model provides an F-CLEAN membrane tensioning device, including a mounting base 1, on which two sets of clamping plates 2 are movably mounted.

[0022] Mounting plates 3 are movably inserted into the upper and lower ends of clamping plate 2. Mounting plates 3 have insertion holes 4. Guide rods 5 are movably mounted on mounting plates 3. Limiting rings 6 are fixedly mounted on guide rods 5. Springs 7 are provided on mounting plates 3. One end of the limiting rings 6 abuts against the springs 7. Adhesive blocks 8 are fixedly mounted on the upper end of guide rods 5.

[0023] The fixing mechanism is mounted on the mounting base 1 and is used to fix the equipment to the purlin.

[0024] The bonding structure is set on the bonding block 8. The bonding structure is used to increase the bonding area between the device and the film. The device uses the elasticity of the spring 7 and the bonding of the bonding block 8 to make the film can be lifted and tensioned, thereby achieving tension on the film in a relaxed state. A fixing mechanism is also provided to make the device easy to assemble and increase the convenience of using the device.

[0025] Furthermore, the fixing mechanism includes a movable groove 9, in which the clamping plate 2 is inserted and moves. A threaded sleeve 10 is fixedly installed at the center of the front end of the clamping plate 2. The threaded sleeve 10 is threaded onto the double-acting screw 11. Fixing blocks 12 are fixedly installed at both ends of the double-acting screw 11. The fixing blocks 12 have hexagonal slots 13, such as... Figure 2 As shown, this structure allows the device to be fixed to the purlin by clamping, increasing the convenience of device fixation.

[0026] Furthermore, damping strips 15 are arranged in an array on opposite sides of the clamping plate 2. The cross-section of the damping strips 15 is L-shaped, and two sets of mounting holes 14 are provided on the mounting base 1, such as... Figure 2 As shown, this structure makes the clamping more stable. In addition, the device can be fixed to the purlin with bolts through the mounting hole 14, which increases the versatility of the device fixing installation.

[0027] Furthermore, the bonding mechanism includes a bonding block 8, which is arc-shaped and the width of the limiting ring 6 is greater than the width of the guide rod 5, such as... Figure 1As shown, this structure allows the bonding block 8 to adhere better to the film, resulting in less pressure from the bonding block 8 on the film and increasing the stability of the equipment during use.

[0028] Furthermore, a shear block 16 is fixedly installed on the lower side of the bonding block 8, and the guide rod 5 is fixedly installed at the center of the shear block 16. Weight reduction holes 17 are arrayed on the shear block 16 and the pull rod 18, such as... Figure 1 As shown, this structure makes the support of the guide rod 5 on the bonding block 8 more stable and makes the bonding block 8 lighter.

[0029] Furthermore, a pull rod 18 is fixedly installed on the lower side of the bonding block 8. The edges of the pull rod 18 are rounded. Figure 1 As shown, this structure makes the device easier to disassemble and also provides better support for the bonding block 8.

[0030] Working principle: When using the equipment, the clamping plate 2 is inserted into the purlin, and then the hexagonal handle is inserted into the hexagonal slot 13 and rotated. This causes the bidirectional screw 11 to move relative to the clamping plate 2 through the thread action between it and the screw sleeve 10. At this time, the insertion hole 4 slides on the clamping plate 2, and the clamping plate 2 clamps the purlin for fixation. Alternatively, the equipment can be fixed to the purlin by inserting bolts into the mounting hole 14. At this time, the upper side of the bonding block 8 is tightly attached to the film and compresses the spring 7. When the film relaxes, the spring 7 will rebound to make the film tense. When disassembling, the hand can hold the pull rod 18 and pull down the bonding block 8 to disassemble the equipment normally. The above is the complete working principle of this utility model.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
