Description

Technical field:

[0001] The utility model belongs to the technical field of greenhouse accessories, in particular to a film pressing clip. Background technology:

[0002] The film pressing clamp is mainly used to fix the greenhouse cover of plastic film or other materials on the greenhouse support. For example, the Chinese utility model patent (Announcement No. CN206617394U, application date 2017.03.13, announcement date 2017.11.07) discloses a film pressing clamp for installing greenhouse film, including a semicircular clamp ring, and a group of first reinforcing ribs and a group of second reinforcing ribs symmetrically arranged on the semicircular clamp ring, and a first strip auxiliary mounting ring and a second strip auxiliary mounting ring respectively arranged at the ends of the semicircular clamp ring, wherein the first strip auxiliary mounting ring and the second strip auxiliary mounting ring are respectively arranged as open structures; the height H of the semicircular clamp ring is 28mm-32mm, and the length L between the first strip auxiliary mounting ring and the second strip auxiliary mounting ring is 8mm-13mm.

[0003] The shed cover includes a main shed that is covered on the side of the shed support and a door shed that is arranged at both ends of the shed support. Due to the requirements of entry and exit and ventilation, the door shed often needs to be disassembled, so an elastic rope is usually set at the end of the shed set with the door shed to tighten and fix it. In order to improve the connection strength between the door shed and the end of the shed, an L-shaped hook is set in the middle of the film pressing clamp on the market to hook the door shed. However, its disadvantage is that the corners of the L-shaped hook are relatively sharp, and the contact area between the corners and the door shed is small, which can easily pierce the door shed. Summary of the invention:

[0004] The utility model aims to provide a film pressing clamp, the contact area between the corner of the film pressing clamp and the door shed is large, and the door shed is not easy to be pierced.

[0005] The utility model is achieved in this way:

[0006] A film pressing clamp comprises a film pressing clamp body and an L-shaped hook arranged on the outer periphery of the film pressing clamp body, the L-shaped hook comprises a longitudinal rod and a vertical rod perpendicular to each other, one end of the longitudinal rod is connected to the outer periphery of the film pressing clamp body, and the other end is connected to the vertical rod, and a cross bar is arranged at the corner of the L-shaped hook, and the cross bar is perpendicular to the plane formed by the longitudinal rod and the vertical rod.

[0007] In the above-mentioned film pressing clamp, the front end surface of the cross bar is flush with the front end surface of the vertical bar, and the lower end surface of the cross bar is flush with the lower end surface of the longitudinal bar.

[0008] In the above-mentioned film pressing clamp, the cross-section of the longitudinal rod and the cross-section of the vertical rod are both rectangular, and the four corners are transitioned through rounded corners, and the length direction of the rectangle is arranged in the horizontal direction.

[0009] In the above-mentioned film pressing clamp, the radius of the rounded corner 1 is in the range of 2 mm to 4 mm.

[0010] In the above-mentioned film pressing clamp, the cross section of the cross bar is square, and the four corners are transitioned through rounded corners.

[0011] In the above-mentioned film pressing clamp, the radius of the second rounded corner is in the range of 2mm-4mm.

[0012] In the above-mentioned film pressing clamp, the two end faces of the horizontal rod and the side face are both transitioned through rounded corners three times, and the end face of the vertical rod away from the longitudinal rod and the side face are transitioned through rounded corners four times.

[0013] In the above-mentioned film pressing clamp, the cross bar is symmetrical about the symmetry axis of the L-shaped hook.

[0014] In the above-mentioned film pressing clamp, a through hole for the screw to pass through is provided on the film pressing clamp body.

[0015] The outstanding advantages of the utility model compared with the prior art are:

[0016] 1. The utility model provides a cross bar at the corner of the L-shaped hook, and the cross bar is perpendicular to the plane formed by the longitudinal bar and the vertical bar, which effectively increases the contact area between the corner and the door shed, making it difficult to pierce the door shed;

[0017] 2. The film pressing clamp body of the utility model is provided with a through hole for screws to pass through. The screws pass through the through hole and are screwed to the door shed bracket, which effectively prevents the film pressing clamp body from rotating relative to the door shed bracket and effectively fixes the film pressing clamp.
