Problems solved by technology

[0004] Although the above-mentioned wire tensioner can keep the rope in a tensioned state, it still has the following defects: 1. After the above-mentioned ratchet-type wire tensioner rotates the ratchet to tighten the stay rope on the installation shaft, it is all installed by assembling the anti-reverse The buckle is used to prevent the wire rope from loosening again, and the check buckle is formed by bending steel wire, which has poor strength and is prone to deformation and failure after a long time. The tensioning effect and the stability after tensioning are poor; 2. The fixing of the above-mentioned ratchet type wire tensioner is to pass through the two through holes on the bending part through the rope and then fixed on the frame of the greenhouse. There is no limit after tightening the drawstring of the greenhouse, and it is prone to displacement, especially for flat laminated ropes, resulting in poor tensioning effect and stability

Embodiment 1

[0036] Such as Figure 1-6 As shown, the belt tightener can be used on a greenhouse, including a bracket 1 and a reel 2 . The bracket 1 has two opposite side plates 1a, a mounting plate 1f at the top, and a connecting portion 1e at the bottom that can be connected to the framework of the greenhouse.

[0037] The connecting part 1e is a connecting plate 1e1, and the connecting plate 1e1 has a circular arc segment 1e11 and a flat plate segment 1e12, the circular arc segment 1e11 is connected with the lower end of one side plate 1a, and the flat plate segment 1e12 is attached to the surface of the other side plate 1a Relying on and riveting through the rivets 3, the gap between the connecting plate 1e1 and the reel 2 can be passed through by the skeleton of the greenhouse. The two ends of the mounting plate 1f are respectively connected with the upper ends of the two side plates 1a in a circular arc transition and have an integrated structure. The mounting plate 1f is provided w...

Embodiment 2

[0043] The structure of the belt tightener of this embodiment is basically the same as that of Embodiment 1, the difference is that: Figure 7-8 As shown, the lower ends of the two side panels 1a have connecting flanges 1g formed by turning inwards, and the two connecting flanges 1g are superimposed and attached to each other. The connecting part 1e is a hook 1e2, and the hook 1e2 includes a hook body 1e21 and a connecting post 1e22 located at one end of the hook body 1e21. Both connecting flanges 1g are provided with through connecting holes and the two connecting holes are oppositely arranged. The hook body 1e21 has a connecting post The end surface of one end of 1e22 abuts against the edge of the connecting hole, and the end of the connecting post 1e22 has a chamfer. The belt tightener is hooked on the crossbeam of the greenhouse frame through the hook 1e2 and then tightened and fixed by the tension force. The hook 1e2 is rotatably connected to the connecting flange 1g, tha...

Abstract

The invention provides a belt tightener, and belongs to the technical field of machines. The problems that an existing tightener is poor in non-return buckling strength and prone to deforming and failing after long time, a pull rope will loosen, and the effect and the stability after tightening are poor are solved. The belt tightener comprises a support and a reel; the support is provided with two opposite side plates, shaft holes are formed in the two side plates, ratchet wheel portions are arranged at the two ends of the reel, are located in the corresponding shaft holes and can rotate in the shaft holes along with the reel, a sinking-in clamping opening is formed in the inner wall of the upper side of each shaft hole, and under the external force effect of the ratchet wheel portions, the ratchet wheel portions can be eccentrically moved to enable one ratchet to be clamped in the corresponding clamping opening. The ratchet wheel portions of the belt tightener are arranged in the shaft holes, after tightening, under the tightening force effect, the ratchet wheel portions can be eccentrically moved to be clamped in the clamping openings, the clamping openings are formed in the support, the whole strength is large, deformation and failures cannot appear even after long time, and the effect and the stability after tightening are good.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a belt tightener. Background technique [0002] Greenhouse is a frame-covered structure with excellent thermal insulation performance. It is a very important facility in the process of modern agricultural production and has been widely used in agricultural production in most areas of our country. Plastic film is a commonly used material in agricultural greenhouses. However, due to the soft material of the plastic film, the area of ​​the greenhouse film is relatively large when used in the greenhouse. Therefore, most of the existing greenhouse films are supported by a rigid frame. , and in order to position the plastic film on the skeleton, it is generally fixed by tightening the rope. [0003] In order to facilitate the tension of the rope, it is generally realized by a tensioner. For example, Chinese patent application (Application No.: 201210338780.1) discloses a ratchet type ...
