Abstract

The utility model discloses a wire winding and unwinding device, and belongs to the field of winding and unwinding devices. The wire winding and unwinding device comprises an upper shell, a lower shell, a volute spiral spring, a rotating whole and a movable clamping tenon. The wire winding and unwinding device is characterized in that the rotating whole is structurally characterized in that the upper end and the lower end of a hollow shaft with a spiral groove formed in the outer circumferential surface are connected with center holes of an upper clamping part and a lower clamping part respectively, the hollow shaft sleeves a shaft lever of the lower shell, a wire is wound in the spiral groove formed in the outer circumferential surface of the hollow shaft, the movable clamping tenon is arranged in a limit groove in the lower shell, a lifting pin telescoping mechanism is fixedly mounted on the lower shell, the central axis of the lifting pin telescoping mechanism and the central axis of the limit groove are positioned on the same straight line, the top end of the lifting pin telescoping mechanism is abutted to the outer arc surface of the movable clamping tenon, and the tail end of the lifting pin telescoping mechanism extends to the outer end through a hole in the lower shell when an accurate wire winding and unwinding length is needed. The wire winding and unwinding device has the advantages of simple structure and convenience in operation.

Description

A kind of wire rod reeling-up reeling-out device

Technical field

The utility model belongs to reeling-up reeling-out device technical field, is specifically related to a kind of wire rod reeling-up reeling-out device.

Background technology

China Patent No. is 201220121746.4 disclosed a kind of wire rod reeling-up reeling-out devices, and it includes upper shell, lower house, volute spiral spring, wire rod, movable latch and runner assembly.The shortcoming that this structure exists is that dismounting more complicated, volume unwrapping wire material are neat not and manipulation activities trip is convenient not and the larger problem of loss of machine of torque.

Summary of the invention

The purpose of this utility model is to provide a kind of improved wire rod reeling-up reeling-out device, can overcome the shortcoming that prior art exists.

The utility model is achieved in that on the basis of constructing at number of patent application 201220121746.4, and the structure to runner assembly and the control mechanism of movable latch improve.As shown in Figure 1, include: upper shell 1, lower house 2, volute spiral spring 3, rotation entirety 4, movable latch 5, knock pin type telescoping mechanism 6, wire rod 7.

The feature of rotating overall structure is as shown in Figure 2,3, the upper and lower side that is shaped with the quill shaft 4-2 of spiral grooves on outer circumference surface is connected with the centre hole of lower fastener 4-3 with upper fastener 4-1 respectively, the central shaft 2-2 that is sleeved on lower house 2 is upper, and wire rod 7 is wound in the spiral grooves of outer circumference surface of quill shaft 4-2.

The feature of movable latch 5 control mechanisms is as shown in Figure 5, movable latch 5 is arranged in the position-limited trough 2-1 of lower house 2, knock pin type telescoping mechanism 6 is fixedly mounted in the hole 2-3 on lower house 2, the central axis of its central axis and position-limited trough 2-1 is same straight line, in the time of the more accurate wire coil of needs degree of lengthening, the top of knock pin type telescoping mechanism 6 and movable latch 5 exterior arc surfaces are inconsistent, and end stretches to outside by the hole 2-3 on lower house 2.

The utility model beneficial effect is: the utility model adopts planar tracks to inlay to the mode of rotating entirety bottom, has reduced loss of machine of torque, has increased part life; Attack outer silk rotating on overall roll, can realize easily wire rod and neatly deposit, play the effect that increases coiling amount.In addition, the control mechanism of movable latch adopts knock pin type telescoping mechanism, is very easy to user's use, is particularly useful for the occasion higher to stretching accuracy requirement.
