Abstract

The utility model relates to a flexible cord clamping head. A main body of the flexible cord clamping head is composed of two support plates and a shim plate in the middle. A driving wheel is arranged in an empty groove between clamping plates. Both ends of a drive shaft are respectively provided with a gear which is meshed with a rack bar. The side surface of each rack bar is connected with a spring sheet. The surfaces of the support plates are respectively fixed with a jack. The jacks contact the spring sheets. The surfaces of the clamping plates are provided with long holes. Shafts of the gears can move in the long holes. A flexible cord can be led in from one end of the driving wheel, can pass round the circumference of the upper part of the wheel, and then can be led out from the other end of the wheel. The shafts of the gears can move up and down in the long holes. The flexible cord can be fixed by the driving wheel, and can not loosen.

Description

Flexible cord clip

The utility model relates to a kind of Flexible cord clip, belongs to the technical field of fixed connection apparatus.

Putting up tent or,, also breaking into fast knot sometimes and be difficult for getting loose if it is very time-consuming that rope is tied a knot, loosened using rope to fix under the situation of some thing, the employing eccentric element is also arranged, and screw thread hold down gag etc. can both tightly fixedly connected rope band, it is also convenient to loosen, shortcoming is fixing poor slightly for circular rope, slippage easily, and when connecting, to operate and to fix rope with the number people, both time-consuming, take manpower again, efficient is too low.

The purpose of this utility model is that a kind of Flexible cord clip will be provided, and it can overcome above-mentioned shortcoming, utilizes the combination of gear mechanism and spring sheet, can fix tightrope, and unlikely slippage, slack rope is also soft easily, and is simple in structure.

The purpose of this utility model is achieved in that

Drive wheel is equipped with in the bottom of body, and the axle head of drive wheel is equipped with gear, this wheel and rack engagement, it is one very heavy that the fixedly connected spring sheet in tooth bar side, body surface are fixed, and very heavyly contacts with spring sheet, tightrope is introduced the top circumference of walking around wheel from drive wheel one end, is drawn by the other end again.

Body is combined by 2 support plates and middle backing plate, and there is slotted hole on the support plate surface.

Fig. 1 is the Flexible cord clip schematic representation.

Fig. 2 is a body backing plate schematic representation.

Fig. 3 is a body support plate schematic representation.

Fig. 4 is the A-A sectional view of Fig. 3.

Fig. 5 is drive wheel and Gear combination figure.

Fig. 6 is the driving mechanism schematic diagram.

Now in conjunction with the accompanying drawings the structure of Flexible cord clip is described in detail:

By Fig. 1, drive wheel (2) is equipped with in the bottom of collet body (1), on the axle of drive wheel (2) gear (3) is housed also, gear (3) be contained in the lip-deep tooth bar of body (1) (4) engagement, also be equipped with on the body support plate (11) one very heavy (5), an end of very heavy (5) contacts with a rubber-like spring sheet (6), and tightrope (7) is introduced by one side of drive wheel (2), walk around the top circumference of wheel, draw downwards again.

By Fig. 2, Fig. 3, body (1) is made up of 2 support plates (11) and a middle backing plate (12) amalgamation, between the bottom of 2 support plates (11), form a dead slot, the drive wheel (2) of can packing into, the axle of drive wheel (2) is bearing in support plate (11) outside, axle head respectively is equipped with a gear (3), each meshes this gear (3) with a tooth bar (4), because support plate (11) has slotted hole (13), the axle of drive wheel (2) can be upper and lower mobile in slotted hole (13), and gear this moment (3) is also gone up at tooth bar (4) and moved.

By Fig. 4, two support plates (11) and a middle backing plate (12) are combined into collet body (1), its top porose (14), drive wheel (2) is contained between the support plate (11), its shaft extension goes out outside the support plate (11), a gear (3) is respectively adorned at two ends, and tooth bar (4) joins together with support plate (11) surface, is meshed with gear (3).

By figure (5), drive wheel (2) is housed on the transmission shaft, gear (3) respectively is equipped with at the two ends of axle.

By Fig. 6, tooth bar (4) and gear (3) engagement are connected with one very heavy (6) on the tooth bar (4), and its end contacts with a spring sheet (6) that is fixed on the support plate (1).During use the tightrope of circular cross-section is introduced the upper circumferential edge of walking around wheel from drive wheel (2) one ends, drive wheel rotates, gear (3) is rotated thereupon, gear (3) is intermeshing with tooth bar (4), so gear (3) drives drive wheel (2) and moves along tooth bar, and the axle of gear (3) can be upper and lower mobile in the slotted hole (13) of support plate (11), when drive wheel (2) when moving up thereupon, drive wheel (2) clamps tightrope (7), at this moment very heavy (5) have not had effect, and gear (3) has arrived the limit position of slotted hole (13).

In drive wheel (2) backward rotation, when promptly clockwise direction rotated, the right-hand member with pulling tightrope (7) moved down, and can stir very heavy (5) downwards simultaneously, and tightrope (7) can become flexible.

Compared with prior art, Flexible cord clip has following advantages:

1. utilize the transmission of gear mechanism, fixing of degree of tightness tightrope makes the unlikely slippage of tightrope.

2. army's tent needs be operated by several people when flat, and it is fixing to knot rope, both time-consuming, and it is difficult to release, and uses this dop, only needs 1 people just can carry out, and both saves time, and also reduces operating personnel's quantity, increases work efficiency.

3. simple in structure, cost is not high, is easy to promote the use of.

Claims

1, a kind of Flexible cord clip, drive wheel (2) is equipped with in the bottom that it is characterized in that collet body (1), the axle head of drive wheel (2) is equipped with gear (3), this gear (3) and tooth bar (4) engagement, the fixedly connected spring sheet in tooth bar (4) side (6), one very heavy (5) are fixed on body support plate (11) surface, and very heavy (5) contact with spring sheet (6), tightrope (7) is introduced the top circumference of walking around wheel from drive wheel (3) one ends, is drawn by the other end again.

2, dop according to claim 1 is characterized in that body (1) is combined by 2 support plates (1) and a middle backing plate (12), and there is slotted hole (13) on support plate (11) surface.
