Abstract

A wire tightening device comprises a cable tray and a wire winder, wherein the wire winder is arranged on the cable tray via a rotating shaft, the wire winder is wrapped with wires, two ends of the rotating shaft are respectively equipped with a wire tightening mechanism and a backstop mechanism, and a wire clamping mechanism is connected with the cable tray. The wire tightening device is characterized in that the wire clamping mechanism is composed of a wire clamping plate rack and a crank-link mechanism, wherein the crank-link mechanism is hinged on the wire clamping plate rack, the hinged end of a crank of the crank-link mechanism and the wire clamping plate rack is equipped with an eccentric wheel, one end of a connecting rod is movably connected with the cable tray. The wire tightening mechanism is composed of a rectangular gear, clamping plates, a double-ratchet block, a spring and a wrench, wherein the rectangular gear is arranged on the rotating shaft, the clamping plates coated on the rotating shaft are respectively disposed on two sides of the rectangular gear, the double-ratchet block and the spring are arranged between the clamping plates, and the wrench is used to connect the clamping plates. The wire tightening device has the advantages that the wire tightening clamps wire firmly, a retaining wire can not be loose in tightening process, and further the wire tightening device is adaptable to wires with various thickness and is safe in using without adding a wrench, which is flexible and convenient in use with fast wire tightening speed and high working efficiency.

Description

Tightener

Technical field

The utility model is particularly related to a kind of tightener.

Background technique

Often need to use the tightener line that is strained and fixed in building, in the power construction.Existing tightener generally is to be made of coil holder, clamp mechanism and stringing mechanism, and its clamp mechanism adopts the clamping of jaw formula, and stringing mechanism is made of with the stringing spanner that other joins the stringing ratchet that is fixed on the roll.The shortcoming of this tightener is: 1, jaw formula clamping clamp is insecure, and static line is easily got loose in the tension process, causes static line to throw away, and causes casualty accident easily; 2, the thickness of the folded static line of jaw formula clamping is limited; 3, inconvenient operation, stringing speed is slow, inefficiency.

Goal of the invention

The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of clamp firm, safe in utilization, flexible, convenient, is suitable for various line styles, and stringing speed is fast, the tightener of high working efficiency.

The utility model is achieved in that it comprises coil holder and is installed in reel on the coil holder by rotating shaft, on reel, be tied with backguy, be respectively equipped with stringing mechanism and stopping mechanism at the rotating shaft two ends, on coil holder, be connected with clamp mechanism, its special way is: described clamp mechanism is made of a clamp grillage and the connecting rod that is hinged on the clamp grillage, wherein the rounded end of the crank of connecting rod and clamp grillage is an eccentric wheel, connecting rod one end and coil holder loose joint; Described stringing mechanism is by the rectangle gear that is installed in the rotating shaft, is sleeved on the clamping plate that lay respectively at rectangle gear both sides in the rotating shaft, and the spanner that is located at two ratchet pieces and the spring between the clamping plate and is connected two clamping plate constitutes.

Above-mentioned tightener, described connecting rod one end is hinged with connecting base, and connecting base is by bolt and coil holder loose joint.

Above-mentioned tightener, described stopping mechanism are ratchet and pawl arrangement.

The utility model has the advantages that: because clamp mechanism adopts eccentric wheel and clamp grillage to grip line, clamp is firm, and static line can not get loose in the tension process, and is safe in utilization, and can be suitable for the line style of various thicknesses; Because stringing mechanism is the integral structure that is formed by connecting by rectangle gear, clamping plate, two ratchet piece and spring and spanner, need not to join in addition spanner, use is flexible, convenient, and stringing speed is fast, high working efficiency.

Description of drawings

Fig. 1 is structural representation of the present utility model (axle such as southwest is surveyed view);

Fig. 2 is structural representation of the present utility model (axle such as the southeast is surveyed view);

Fig. 3 is the structural representation of stringing of the present utility model mechanism.

Among the figure: clamp grillage 1, clamp piece 101, flange 102, spanner 2, clamping plate 3, two ratchet pieces 4, rectangle gear 5, rotating shaft 6, reel 7, coil holder 8, connecting base 9, connecting rod 10, crank 11, bolt 12, hook 13, backguy 14, ratchet 15, ratchet 16, bolt 17, spring holder 18, spring 19, cylindrical body 20.

Embodiment

As shown in the figure, this tightener has a coil holder 8, by rotating shaft 6 reel 7 is installed on coil holder 8, is tied with backguy 14 on reel 7, is provided with hook 13 at backguy 14 front ends.Be positioned at coil holder 8 both sides at rotating shaft 6 two ends and be respectively equipped with stringing mechanism and stopping mechanism, described stringing mechanism is by the rectangle gear 5 that is installed in the rotating shaft 6, be sleeved on the clamping plate 3 that lay respectively at rectangle gear 5 both sides in the rotating shaft 6, be installed in two ratchet pieces 4 and spring holder 18 between the clamping plate 3 by bolt, be installed in the cylindrical body 20 of two ratchet piece 4 lower ends, be sleeved on the spring 19 on the spring holder 18 and be connected two spanners 2 between the clamping plate 3 by bolt and constitute, described spring holder 18 upper ends are inserted in the radial hole that is located on the cylindrical body 20.Described stopping mechanism is by being fixed on the ratchet 15 in the rotating shaft 6 and constituting by the ratchet 16 that is bolted to coil holder 8 one sides.On coil holder 1, be connected with clamp mechanism, described clamp mechanism is made of a clamp grillage 1 and the connecting rod that is hinged on the clamp grillage 1 by bolt 12, wherein the crank 11 of connecting rod is an eccentric wheel with the rounded end of clamp grillage 1, connecting rod 10 1 ends are hinged with connecting base 9, connecting base 9 is by bolt and coil holder 8 loose joints, be connected with a clamp piece 101 corresponding on the clamp grillage 1 with the eccentric wheel on the crank 11, be provided with flange 102 in clamp grillage 1 upper end, between flange 102 and clamp grillage 1, be provided with bolt 17, described connecting rod 10 is by passing between flange 102 and the clamp grillage 1, with the position of limiting rod 10.

During use, the backguy 14 that is wrapped on the reel 7 is all launched and will link up with 13 to hang on the fixed transverse rod, be held in fixing clamper to be strained between eccentric wheel and the clamp piece 101 and pull back clamp grillage 1, rotate two ratchet pieces 4 then, the ratchet parallel with ratchet 16 is snapped on the rectangle gear 5, and another mistake hour hands rotary spanner 2 can be strained static line gradually; When needing loose ends, the opposite side ratchet on two ratchet pieces 4 is snapped on the rectangle gear 5, the spanner 2 that turns clockwise again gets final product.
