Description

Technical Field

[0001] This utility model relates to the field of membrane fabric clip technology, specifically a single-screw membrane fabric clip. Background Technology

[0002] During the production and preparation of membrane fabric, it needs to be stretched. During the stretching process, membrane fabric clamps are required. Traditional membrane fabric clamps require manual adjustment with a wrench, or the membrane fabric clamps have nuts at the bottom, which often cause the membrane fabric to rub against the wires. In view of this, this device was designed to address the above problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a single-screw membrane cloth clamp, which solves the problem that existing membrane cloths require stretching during production and preparation, and that traditional membrane cloth clamps require manual adjustment using a wrench.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a base plate, on which a threaded rod with an inclined angle is provided, and an arc-shaped plate is fitted onto the threaded rod. A pair of arc-shaped limiting blocks are provided on the base plate at the edge of the pull hole, with one end of the arc-shaped plate located within the arc-shaped limiting blocks. A nut is fitted onto the threaded rod, and a ring handle is installed on the nut to form a lifting ring. A spring is fitted onto the threaded rod and below the arc-shaped plate, with the spring located between the base plate and the arc-shaped plate.

[0005] Pull holes are provided on the base plate.

[0006] The sidewall of the base plate, located on the side with the pull hole, is machined into an arc shape.

[0007] The circular through-holes in the arc-shaped plate allow for the insertion of threaded rods. The arc-shaped plate is made of pressed steel plate or profiled steel.

[0008] This utility model provides a single-screw membrane cloth clamp. It has the following advantages: by clamping the edge of the membrane cloth, it is easy to stretch the membrane cloth, and the operation is convenient. The bottom is smooth and will not scratch other objects or the membrane cloth. Attached Figure Description

[0013] 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.

[0014] Please see Figure 1-3 This utility model provides a technical solution: a single-screw film clip, including a base plate 1, a threaded rod 2 with an inclined angle on the base plate 1, an arc plate 3 fitted on the threaded rod 2, a pair of arc-shaped limiting blocks 4 located at the edge of the pull hole on the base plate 1, one end of the arc plate 3 located inside the arc-shaped limiting block 4, a nut 5 fitted on the threaded rod 2, an annular handle 6 installed on the nut 5 to form a lifting ring, and a spring 7 fitted on the threaded rod 2 and below the arc plate 3, the spring 7 being located between the base plate 1 and the arc plate 3;

[0015] It should be noted that: the threaded rod 2 on the base plate 1 facilitates the insertion of the arc plate 3. The screw rod 2 is installed at an angle, which makes it easy for one end of the arc plate 3 on the screw rod 2 to open at an angle, while the other end is located in the arc-shaped limiting block 4. The spring 7 is located between the base plate 1 and the arc plate 3. The spring 7 itself is elastic and can extend and retract. The nut 3 and the ring handle 6 form a lifting ring. When the lifting ring is turned clockwise, the lifting ring moves downward, thereby squeezing the arc plate 3 downward. The spring 7 is compressed and will not obstruct the arc plate 3 from moving downward. When the lifting ring is turned counterclockwise, the lifting ring rises and will not squeeze the arc plate 3. Therefore, the spring 7 will not be subjected to squeezing force, so it extends and resets, lifting the arc plate 3 and creating a distance between the arc plate 3 and the base plate 1. One end of the arc plate 3 is located in the arc-shaped limiting block 4. The arc-shaped limiting block 4 limits the arc plate 3 and prevents the arc plate 3 from shifting.

[0016] In use, the lifting ring can be turned counterclockwise to raise it, thereby lifting the arc plate 3 through the spring 7. The membrane cloth can then be inserted between the arc plate 3 and the base plate 1. After that, the lifting ring can be turned clockwise to push the arc plate 3 downward, thereby clamping the membrane cloth between the arc plate 3 and the base plate 1. This makes it easy for the hook to catch the pull hole and pull the membrane cloth through this device.

[0017] It should be noted that the threaded rod 2 can be installed vertically without the spring 7. It is still possible to open the arc plate 3 by turning the lifting ring, and then place the membrane cloth between the arc plate 3 and the base plate 1, and then turn the lifting ring to clamp the membrane cloth.

[0018] As a preferred technical solution, the base plate 1 is further provided with pull holes; the pull holes facilitate manual use of the device.

[0019] As a preferred technical solution, the side wall of the base plate 1, located on the side of the hole, is further processed into an arc shape; the arc-shaped edge facilitates the manual hole-pulling position.

[0020] As a preferred technical solution, the circular through hole on the arc plate 3 is used to insert the arc plate 3 into the threaded rod 2. The arc plate 3 is made of steel plate or profiled steel. The circular through hole facilitates the insertion of the arc plate 3 into the threaded rod 2.

[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
