Abstract

The utility model relates to a film pressing clamp, which is mainly used for fixing a film pressing line of a shanty. The clamp has an inclined groove. A cam block is arranged in the inclined groove. A hole of the clamp and a hole of the cam block are inserted by a copper tube to achieve the fixation. A clearance between the cam block and the bottom of the groove is from big to small to make the film pressing line be compacted and slide difficultly. The clamp is fixed on foundation by wires. The clamp is convenient to assemble and disassemble and does not need to be knotted.

Description

Film pressing clamp

The utility model relates to the press mold dop that a kind of fixed plastics canopy is used, and belongs to the technical field of fastenings.

Plastic greenhouse often uses the banded film-pressing line of plastics to fix at present, its two ends adopt the mode that knots to be connected with lower margin, because being easy to skid, film-pressing line takes place to become flexible, shed is tilted, winter, film-pressing line became cold short, also be easy to when knotting fracture, therefore be badly in need of having a kind of setting tool of simple and easy practicality to satisfy above-mentioned requirement.

The purpose of this utility model is that a kind of film-pressing line dop will be provided, and it can overcome above-mentioned deficiency.

The purpose of this utility model is to realize like this, utilize duroplasts or metallic material to make a kind of dop, dop top has tipper dop two ends that a hole is respectively arranged, make little axle with steel pipe in the groove and fix a cam bit (5), cam bit (5) can be swung in groove, and the crack can change between the skewed slot bottom, when film-pressing line enters this gap, cam bit utilizes its circular arc portion that film-pressing line is pressed on bottom land, make film-pressing line unlikely loosening, as the loosening film-pressing line of need, as long as rotatable cam blocks just can achieve the goal, in addition, bottom land partly can make has the flexuose part, the circular arc portion of cam bit makes the respective saw teeth shape, utilizes both sawtooth to compress film-pressing line.

Now be described in detail as follows to the structure of film-pressing line in conjunction with the accompanying drawings:

By Fig. 1, dop (1) is to make with ABS engineering plastics or metallic material, and its two ends are circular arc, and upper left quarter has a nose, upper and lower end each porose (2), (3).

By Fig. 2, a tipper (4) is arranged at dop (1) top, and the hole (3) of the hole on top (2) and bottom all is a through hole, and bottom land is a straight line; But can be a circular arc.

Fig. 3 is the schematic representation of cam bit (5), and it is also made with same material, its porose (6), and the aperture is consistent with hole (2), (3) of dop.

Fig. 4 is the schematic representation that dop compresses film-pressing line, cam bit (5) is inserted in the tipper (4) of dop (1), its hole (6) aligns with the hole (2) of dop (1), insert in the hole with copper pipe (7) then, the end face of dop (1) is lived in two riveting, cam bit (5) can be rotated in groove (4), when the side of cam bit parallels with bottom land, its gap is bigger, and the film-pressing line (8) of can packing into this moment makes the wire-wound cam bit rotate then, cam bit (5) also rotates, the gap is reduced, till the circular arc portion of cam bit (5) compresses film-pressing line (8), at this moment be difficult for extracting out film-pressing line (8).

The hole (3) of dop (1) bottom is to be used for fixing (Fig. 4 slightly) with the hole of ground lower margin with galvanized wire, and every film-pressing line (8) just can be fixed on the lower margin hole as long as each is with a dop (1) at two.

Fig. 5 is the schematic representation of band saw tooth dop (9), the body of dop (9) also with Fig. 1 in the shape approximation of dop (1), the hole of its underpart (11) also is used for fixedlying connected with lower margin, but the hole on top (10) are suitable with the hole (2) among Fig. 1, but bottom land (12) is approached in its position, and the top of dop (9) promptly has sawtooth (13) on the top of bottom land.

Fig. 6 is the side view of band saw tooth dop, and sawtooth (13) is arranged in the upper slot of dop (9), and the hole of groove both sides (10) are to be used for penetrating copper pipe (7) with stationary cam piece (15).

Accompanying drawing 7 is schematic representation of the cam bit of band saw tooth, cam bit (5) porose (16) has same diameter with the hole (10) of dop, one side in hole (16) has sawtooth (14) part, intermesh with the sawtooth (13) of dop (9), can tighten film-pressing line (8), the effect of chucking also is better than anodontia cam bit.

Fig. 8 is the schematic representation of dop chucking film-pressing line, cam bit (15) utilizes copper pipe (7) to penetrate the hole (10) of dop and the hole (16) of cam bit (15), cam bit is fixed on above the dop, when film-pressing line (8) through between the sawtooth (13), (14) along the profile of cam bit (15) when counterclockwise mobile to the right, film-pressing line drives the cam bit rotation, make its sawtooth (14) tight line pressure, since the right-hand member of cam bit (15) from the hole distance of (16) greater than hole (16) distance to sawtooth (19), laborsaving when making clamping, and effect is preferable.

Compared with prior art, the utility model film pressing clamp has following advantages:

1, the dop cam bit has self-locking action, makes film-pressing line unlikely loosening, and therefore fixedly the effect of film-pressing line is better.

2, loading and unloading are simple and easy, avoided the film-pressing line Fastener to be easy to the situation of skidding or fractureing.

3, simple in structure, be easy to make, and aspect the article packing, use.
