Clamping device for clamping films

Abstract

The invention discloses a clamping device for clamping films, comprising a film pressing strip (1), a buckling element and a film pressing strip fixed structure, wherein the film pressing strip (1) is provided with a groove (11) which is in run-through on two ends; the buckling element can be clamped in the groove (11) of the film pressing strip (1) in a detachable mode to clamp the films; the film pressing strip fixed structure fixes the film pressing strip (1) on a strut bar. The clamping device is characterized in that the upper edge and the lower edge of the opening of the groove (11) of the film pressing strip (1) are oppositely provided with an extending blocking part (12) which is generally parallel to the bottom of the groove. The structure has the advantages that the buckling element can be stably clamped and fixed in the groove of the film pressing strip due to the blockage of the extending blocking parts when the buckling element is clamped in the groove of the film pressing strip, thereby being capable of firmly clamping the film in the groove of the film pressing strip. The clamping device has simple and reasonable design structure.

Description

technical field [0001] The invention relates to a clamping device for clamping a film on a lamination strip. Background technique [0002] In the prior art, the clamping device used for clamping the film on the film strip is as Figure 7 As shown, its structural design is unreasonable. When the buckle is buckled in the groove of the film-pressing strip, the buckle is easy to slip or fall out of the groove of the film-pressing strip, so the firmness of the buckle and The stability is often not enough, which will bring inconvenience to the vegetable or fruit growers; moreover, the grooves are prone to water accumulation, which will cause rust and rot, which will affect the service life, so how can the plastic film be better, more convenient and more secure? Being stuck in the groove of the laminated strip has become an important issue. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a clamping device for clamping ...
