Abstract
The utility model discloses a lifting claw for an enamelled wire spool. The lifting claw for the enamelled wire spool comprises a hoisting ring, wherein two first connecting rods are hinged with the hoisting ring; the two first connecting rods are respectively hinged with second connecting rods; the second connecting rods are hinged in an intersecting manner; claw arms are respectively hinged with the second connecting rods; a spring is arranged between the claw arms; a claw hook which transversely extends is arranged at the bottom part of each claw arm; claw teeth are arranged at the top parts of the claw hooks; addendum angles of the claw teeth are acute angles; and the addendum angles of the claw teeth face to the claw arms. The lifting claw disclosed by the utility model can safely and reliably grab the spool; and the claw hooks hook the inner wall of a hoisting hole after the claw arms are embedded into the hoisting hole of the spool. Therefore, on one hand, the spring generates restoring force after being compressed; and two claw arms have the trend of reversely moving outwards, so as to push the claw hooks on the claw arms to hook the inner wall of the hoisting hole; and on the other hand, the addendum angles of the claw teeth on the claw hooks face to the claw arms, the friction force between the claw hooks and the hoisting hole is increased; and the claw hooks and the inner wall of the hoisting hole are further prevented from oppositely moving to avoid separation, so that the lifting claw is safe and reliable to grab.
Description
Technical field
The utility model relates to a kind of enamel wire bobbin with hanging pawl.
Background technology
Enamel wire is a principal item of winding wire, is made up of conductor and two ones of insulating barriers, and bare wire forms through repeatedly painting, curing behind annealing softening again.Namely meet standard-required but produce, satisfy the product of customer requirement again and be not easy, it is subjected to raw material quality, technological parameter, production facilities, factor affecting such as environment.Existing enamel wire adopts bobbin to carry out take-up, by hanging the pawl handling, hangs in the hole for hoist that pawl embeds bobbin, hangs pawl and is connected unreliablely with bobbin but exist, and case accident when causing handling causes potential safety hazard.
The utility model content
The utility model purpose is to provide a kind of enamel wire curing range of energy-conserving and environment-protective.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of enamel wire bobbin is with hanging pawl, comprise suspension ring, suspension ring are hinged with two first connecting rods, it is characterized in that: two hinged second connecting rods of first connecting rod difference, the mutual cross-articulation of second connecting rod, second connecting rod is the hinge finger arm respectively, is provided with spring between two pawl arms, the bottom of pawl arm is provided with the claw hook of horizontal expansion, and the top of claw hook is provided with blade tooth.
Further, the addendum angle of blade tooth is acute angle, and the addendum angle of described blade tooth is towards described pawl arm.
The utility model has following beneficial effect owing to adopted technique scheme:
Hang pawl and can grasp bobbin safely and reliably, after the pawl arm embeds the hole for hoist of bobbin, claw hook catches on the inwall of hole for hoist, the compressed back of spring produces restoring force on the one hand, make two pawl arms have the trend of outwards moving dorsad mutually, thereby the claw hook on the driving pawl arm tightly catches on the inwall of hole for hoist, on the other hand on the claw hook addendum angle of blade tooth towards the pawl arm, increased the friction force between claw hook and the hole for hoist, prevent that further melon hook and hole for hoist inwall from producing relative motion and break away from, make grasp safe and reliable.The utility model is simple in structure, and low cost of manufacture is practical.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of enamel wire bobbin of the utility model structural representation that hangs pawl;
Fig. 2 is the connection structure scheme drawing in the utility model embedding bobbin hole for hoist.
The specific embodiment
As depicted in figs. 1 and 2, for a kind of enamel wire bobbin of the utility model with hanging pawl, comprise suspension ring 1, suspension ring 1 are hinged with two first connecting rods 2, two hinged second connecting rods 3 of first connecting rod 2 difference, second connecting rod 3 mutual cross-articulation, the Joint strenght height, structural safety is reliable, second connecting rod 3 is hinge finger arm 4 respectively, being provided with spring 5 between two pawl arms 4, is the virgin state of spring shown in Fig. 1, and the bottom of pawl arm 4 is provided with the claw hook 6 of horizontal expansion, the top of claw hook 6 is provided with blade tooth 7, the inwall that the tooth top of blade tooth 7 props up the hole for hoist 9 of bobbin 8 grasps, and the addendum angle of blade tooth 7 is acute angle, and the addendum angle of described blade tooth 7 is towards described pawl arm 4.Utility model is hung pawl can grasp bobbin 8 safely and reliably, after pawl arm 4 embeds the hole for hoist of bobbin 8, claw hook 6 catches on the inwall of hole for hoist 9, spring 5 is compressed, spring 5 compressed backs produce restoring force on the one hand, make two pawl arms 4 have the trend of outwards moving dorsad mutually, thereby the claw hook 6 on the driving pawl arm 4 tightly catch on the inwall of hole for hoist 9; The addendum angle of blade tooth 7 has increased the friction force between claw hook 6 and the hole for hoist 9 towards pawl arm 4 on the claw hook 6 on the other hand, prevents that further melon hook and hole for hoist 9 inwalls from producing relative motion and break away from, make grasp safe and reliable.
Only be specific embodiment of the utility model below, but technical characterictic of the present utility model is not limited thereto.Any based on the utility model, for realizing essentially identical technique effect, done the ground simple change, be equal to replacement or modification etc., all be covered by among the protection domain of the present utility model.
Claims (2)
1. an enamel wire bobbin is with hanging pawl, comprise suspension ring, described suspension ring are hinged with two first connecting rods, it is characterized in that: described two first connecting rods are hinged second connecting rod respectively, the mutual cross-articulation of described second connecting rod, described second connecting rod is the hinge finger arm respectively, is provided with spring between described two pawl arms, the bottom of described pawl arm is provided with the claw hook of horizontal expansion, and the top of described claw hook is provided with blade tooth.
2. a kind of enamel wire bobbin according to claim 1 is with hanging pawl, and it is characterized in that: the addendum angle of described blade tooth is acute angle, and the addendum angle of described blade tooth is towards described pawl arm.
