Abstract

A clamp comprises a clamping seat, a screw rod and a clamping belt, wherein a central axis is limited by the screw rod; a lengthwise central line is limited by the clamping belt; the clamping belt is provided with a first end part and a second end part opposite to the first end part in the direction of the lengthwise central line; the screw rod and the first end part of the clamping belt are mounted on the clamping seat in a manner that the central axis is in parallel with the lengthwise central line; the first end part is fixedly connected with the clamping seat; the screw rod can only rotate around the central axis relative to the clamping seat; and a clearance is limited between part of the threads of the screw rod and the first end part of the clamping belt. The clamp is characterized in that a plurality of concave-convex stripes are formed through pressing between the first end part and the second end part of the clamping belt at equal intervals, and the intervals and directions of the concave-convex stripes can be in matched screw joint with the threads of the screw rod.

Description

A kind of clip

Technical field

The utility model relates to a kind of clip of easy adjustment.

Background technique

Existing a kind of clip, comprise a deck, a screw rod and a cassette tape, described screw rod limits a central axis, described cassette tape limits a lengthwise center line, described cassette tape has a first end and one and first end opposite second end along this lengthwise centerline direction, the first end of described screw rod and described cassette tape is mounted on deck described central axis and described lengthwise center line is parallel to each other, described first end is fixedlyed connected with deck, described screw rod can only rotate with respect to deck around its medial axis, limit a gap between a part in the described screw flight and the first end of described cassette tape, wherein said cassette tape has the uniform cross-drilled hole in some intervals between from the second end to the first end, and the spacing of described cross-drilled hole and orientation can form with screw flight and cooperate precession to concern.

Its shortcoming is that perforate has weakened the tensile strength of cassette tape greatly, has aggravated stress and has concentrated.Particularly wait under the dynamic stress condition in vibration, the tensile fatigue strength of cassette tape is impaired bigger.

The model utility content

For this reason, the utility model provides a kind of clip, comprise a deck, a screw rod and a cassette tape, described screw rod limits a central axis, described cassette tape limits a lengthwise center line, described cassette tape has a first end and one and first end opposite second end along this lengthwise centerline direction, the first end of described screw rod and described cassette tape is mounted on deck described central axis and described lengthwise center line is parallel to each other, described first end is fixedlyed connected with deck, described screw rod can only rotate with respect to deck around its medial axis, limit a gap between a part in the described screw flight and the first end of described cassette tape, it is characterized in that, described cassette tape is pressed with the uniform concavo-convex striped in some intervals between from the second end to the first end, and the spacing of described concavo-convex striped and orientation can form with screw flight and cooperate precession to concern.

Description of drawings

Fig. 2 is a clip deployed condition schematic representation of the present utility model.

Embodiment

As illustrated in fig. 1 and 2, a kind of clip, comprise a deck 20, a screw rod 30 and a cassette tape 10, described screw rod limits a central axis, described cassette tape limits a lengthwise center line, described cassette tape has a first end 12 and one and first end opposite second end 11 along this lengthwise centerline direction, the first end 12 of described screw rod 30 and described cassette tape 10 on deck 20, be mounted to make described in bobbin thread and described lengthwise center line be parallel to each other, described first end is fixedlyed connected with deck, described screw rod 30 can only rotate with respect to deck 20 around its central axis, limit a gap between a part in the screw thread of described screw rod 30 and the first end of described cassette tape 12, wherein, described cassette tape 10 is pressed with the uniform concavo-convex striped 15 in some intervals 12 from the second end 11 to first end, the spacing of described concavo-convex striped and orientation can form the precession relation that cooperates with the screw thread of screw rod 30.

Like this, in use, just cassette tape 10 can be gone for a stroll, its second end 11 is injected described gap, make that the screw thread on the concave and convex stripe and screw rod 30 is meshing with each other on the cassette tape.By the turn screw rod, with regard to stretchy cassette tape 10, come clip to live object, particularly column or accurate column thereby tighten up collar.

Cassette tape 10 can be made by thin metallic material, makes it have tensile strength and flexility concurrently.

Better, at the lengthwise centerline direction perpendicular to cassette tape, the ratio between described concavo-convex striped length d and the cassette tape width D is 10-50%.Best, this ratio is 20-35%.Like this, concavo-convex striped is just less to the influence of the flexibility of cassette tape, and it is submissiveer to be that cassette tape and clip use.

Claims

1. clip, comprise a deck, a screw rod and a cassette tape, described screw rod limits a central axis, described cassette tape limits a lengthwise center line, described cassette tape has a first end and one and first end opposite second end along this lengthwise centerline direction, the first end of described screw rod and described cassette tape is mounted on deck described central axis and described lengthwise center line is parallel to each other, described first end is fixedlyed connected with deck, described screw rod can only rotate with respect to deck around its medial axis, limit a gap between a part in the described screw flight and the first end of described cassette tape, it is characterized in that, described cassette tape is pressed with the uniform concavo-convex striped in some intervals between from the second end to the first end, and the spacing of described concavo-convex striped and orientation can form with screw flight and cooperate precession to concern.

2. clip as claimed in claim 1 is characterized in that, at the lengthwise centerline direction perpendicular to cassette tape, the ratio between described concavo-convex striped length and the cassette tape width is 10-50%.

3. clip as claimed in claim 2 is characterized in that, at the lengthwise centerline direction perpendicular to cassette tape, the ratio between described concavo-convex striped length and the cassette tape width is 20-35%.
