Abstract
A clamping device of clamp thin film comprises a squeeze film strip (1), a clamp piece and a squeeze film strip fixing structure, wherein a groove (11) which threads through two ends is arranged on the squeeze film strip (1), the clamp piece is detachably clamped in the groove (11) of the squeeze film strip (1) to clamp thin films, and the squeeze film strip (1) is fixed on a support bar by the squeeze film strip fixing structure. The clamping device is characterized in that the upper edge and the lower edge of the opening of the groove (11) of the squeeze film strip (1) are oppositely provided with an extended barrier portion which is generally parallel to the bottom of the groove. The clamping device has the advantages that when the clamp piece is clamped in the groove of the squeeze film strip, the clamp piece can be firmly and stably clamped in the groove of the squeeze film strip because of the blocking of the extended barrier portion, thereby thin films can be firmly clamped in the groove of the squeeze film strip. The clamping device has simple design structure, and the design structure is very reasonable.
Description
Technical field
The utility model relates to a kind of clamping device that is used for clamping films on the press mold bar.
Background technology
In the prior art, the clamping device that is used for clamping films on the press mold bar as shown in Figure 7, its structural design is unreasonable, when fastener is snapped in the groove of press mold bar, fastener is easy to skid off from the groove of press mold bar or deviate from, so the fastness of buckle and stability are often not enough, this can make vegetable grower or orchard worker bring inconvenience in the use; And the easy ponding of groove produces the mashed phenomenon of rust, influences service life, so how can plastic foil be fastened in the groove of press mold bar better, more convenient, more firmly, has become an important problem.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, simple in structure, easy to use and fastener can place to firm stable the clamping device of the clamping films of press mold bar groove at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of clamping device of clamping films, it includes press mold bar, fastener, press mold bar fixed structure, the press mold bar is provided with the groove that runs through two ends, described fastener detached type is placed in the groove of press mold bar and clamps film, press mold bar fixed structure is fixed in the press mold bar on the support bar, it is characterized in that: the last lower edge at its slot opening place of described press mold bar is provided with the extension stop part parallel substantially with bottom portion of groove in opposite directions.
As improvement, described extension stop part is an extension edge, and this extension edge is the double-layer folded edge that the bead edge contraction of press mold bar forms, and can improve intensity, convenient again the manufacturing.
As improvement, described extension stop part and bottom portion of groove angle are controlled in 5 degree, to produce good blocking effect, prevent that fastener from skidding off.
As preferably, described fastener adopts flexible steel wire bar, jump ring or elasticity fixture block.
At last, described press mold bar fixed structure: include collar and collar locking bolt, and the bottom portion of groove compartment of terrain of press mold bar have collar can wear around bar seam district, each bar seam district cause have less two for collars wear around the bar seam, and each bar seam district is corresponding with a collar, and when press mold bar positioning and fixing, collar is around in the bar seam district, simultaneously with collar around the support bar place, and the press mold bar is fixed on the support bar by collar locking bolt.
Compared with prior art, the utility model adopts in the two edge levels at press mold bar slot opening place and to being provided with the extension stop part mutually, the advantage of this structure is when fastener is placed in the groove of press mold bar, fastener can be fastened in the groove of press mold bar to firm stable owing to extend stopping of stop part, thereby film securely in the groove of holding ground press mold bar, can be realized that film stably is folded on the press mold bar; And structure of the present utility model just is provided with the extension stop part at the groove mouth of press mold bar, so project organization is simple, but project organization is very reasonable again; Also has press mold bar fixed structure of the present utility model: adopt to include collar and collar locking bolt, and the bottom portion of groove compartment of terrain of press mold bar have collar can wear around bar seam district, each bar seam district cause have less two for collars wear around the bar seam, and each bar seam district is corresponding with a collar, when the press mold bar is located, being around in the bar seam district of collar located collar simultaneously around the location, and by collar locking bolt the press mold bar is fixed in the place, location; This structure has solved the ponding problem of press mold bar bottom portion of groove effectively, reduces to rot, because be provided with bar seam district at press mold bar bottom portion of groove, ponding can spill in the bar seam, thereby has guaranteed that press mold bar bottom portion of groove is in drying regime; And can better, more firmly the press mold bar be fixed in the place, location by collar and collar locking bolt; Therefore the utility model is a kind of very practical product, is worthy of popularization.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Extremely shown in Figure 6 as Fig. 1, the clamping device that is used for clamping films on the press mold bar of present embodiment, comprise press mold bar 1, fastener, press mold bar fixed structure, press mold bar 1 is provided with the groove 11 that runs through two ends, the fastener detached type is placed in the groove 11 of press mold bar 1, press mold bar fixed structure is fixed in the support bar place with press mold bar 1, the last lower edge of groove 11 opening parts of press mold bar is provided with in opposite directions extends stop part 12, it is parallel substantially with bottom portion of groove to extend stop part 12, generally will extend stop part 12 and be controlled in 5 degree with groove 11 bottom angles.This extends stop part 12 is extension edge, and this extension edge is the double-layer folded edge that the bead edge contraction of press mold bar 1 forms, thus easy to make, and simple in structure.Fastener adopts flexible steel wire bar 2, can certainly be jump ring or elasticity fixture block, specifically can decide by designing requirement.Press mold bar fixed structure is: include collar 3 and collar locking bolt 31, and bottom portion of groove 13 compartment of terrains of press mold bar 1 have collar 3 can wear around bar seam district, each bar seam district cause have less two for collars 3 wear around bar seam 14, and each bar seam district is corresponding with a collar 3, when press mold bar 1 positioning and fixing, collar 3 is around in the bar seam 14 in bar seam district, simultaneously with collar 3 on the support bar at location place, and by collar locking bolt 31, pin taking out tight collar, thereby press mold bar 1 is fixed on the support bar at place, location.
