Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

The utility model provides a wire winding and unwinding devices through the winding and unwinding devices who adopts this scheme, when releasing or rolling the wire, the promotion simple operation that can be very big.

Referring to fig. 1-2, the retraction device mainly comprises a case 100, a mandrel 200 and a turntable 300; wherein the case 100 has a hollow structure, and the spindle 200 and the turntable 300 are built in the case 100. Specifically, the mandrel 200 is of a paper structure and is disposed at a central position of the case 100, and turntables 300 are fixed to both ends of the mandrel 200; the spindle 200 and the turntable 300 cooperate to form a winding reel in the shape of an "I" as is currently common in the market. The wire is wound around the winding reel, and the winding reel is built in the box body 100, so that the wire can be prevented from being disordered or wound under the protection of the box body 100.

In this solution, in order to implement the winding function, an unwinding adaptor 400 is provided, where the unwinding adaptor 400 penetrates through an end plane of the box 100; the turnplate 300 is in one-to-one correspondence with the unreeling adaptor 400, and an external driving device (not shown) drives the unreeling adaptor 400, so that the turnplate 300 rotates relative to the box 100.

It can be understood that in this embodiment, the mandrel 200 is fixedly connected with the turntable 300, the winding roll formed by the mandrel 200 and the turntable 300 is built in the box 100, the unreeling adaptor 400 is in one-to-one correspondence with and fixedly connected with the turntable 300, and the turntable 300 is rotatably connected with the end plane of the box 100 through the transfer function of the unreeling adaptor 400.

When performing the paying-off operation, the user only needs to pull one end of the wire, and the whole winding roll can be pulled under the action of the pulling force, so that the winding roll and the unreeling adapter 400 rotate relative to the box 100. When winding the wire, under the action of external force (i.e. the driving device), the acting force is applied to the unreeling adaptor 400, and the unreeling adaptor 400 drives the winding roll inside the box 100 to reversely rotate, so that the purpose of winding the wire can be achieved.

Alternatively, referring to fig. 3-7, the unwind adaptor 400 mentioned in this scenario includes a face plate 411 and an adaptor shaft 412; the face plate 411 and the adapter shaft 412 are fixed to form a T shape; the face plate 411 is located outside the end plane of the box body 100, and is convenient to be matched and connected with an external driving device; the adapter shaft 412 passes through an end plane of the case 100 and is fixed to the turntable 300.

In the scheme, in order to be suitable for driving devices with various specifications and types; a concave polygonal hole 4111 is arranged on the end plane of the face plate 411 facing away from the box body 100; the driving device drives the unreeling adapter 400 to rotate through the polygonal hole 4111.

The projections of the polygonal holes 4111 may be triangular, square, pentagonal, hexagonal, etc.; this makes it possible for the drive to be a manual wrench with polygonal projecting tips, or an electric wrench, such as a manual or electric hexagonal wrench, to be preferred; thus, under the driving action of the driving devices, the unreeling adaptor 400 can be rotated easily, and then the winding roll (the combination of the mandrel 200 and the turntable 300) inside can synchronously carry out reeling operation.

Preferably, the polygonal holes 4111 may be hexagonal, straight or cross-shaped or other polygonal internal groove structures.

In other embodiments, the face plate 411 itself may be designed in a polygonal shape, such as the face plate 411 being designed as a regular hexagon; the driving device is a manual wrench or an electric wrench with a plurality of hexagonal concave ends.

The assembly process of this solution can therefore be generalized as: firstly, assembling the mandrel 200 and the turntable 300 to be a winding roll; then the winding roll is built into the box 100; finally, the reel is rotatably connected with respect to the case 100 by connecting the reel adapter 400 to the turntable 300.

In order to be more convenient and quick when the unreeling adaptor 400 is finally installed, in this embodiment, the adaptor shaft 412 in the unreeling adaptor 400 is connected to the turntable 300 in a clamping and fixing manner.

Specifically, the free end of the adapter shaft 412 is provided in a flap shape; and has an outwardly projecting flange 4121 at the free end of the adapter shaft 412; meanwhile, an inner ring cylinder shaft 311 extending towards the direction of the mandrel 200 is arranged in the turntable 300, and a gap is formed at the free end of the inner ring cylinder shaft 311; when the unreeling adapter 400 is pushed from outside to inside to be connected with the turntable 300, the adapter shaft 412 is connected and matched with the turntable 300 until the flange 4121 is clamped at the notch; in this manner, the snap-fit is performed, and the unreeling adapter 400 does not move axially.

The flange 4121 is engaged with the notch 3111 of the inner ring shaft 311 to form a driving connection, so that the faceplate can drive the adaptor shaft 412 to rotate, and it should be noted that various other driving connections are included in the scope of the present utility model.

Considering that the unreeling adaptor 400 has a cylindrical-like structure, when the unreeling adaptor is in fit connection with the turntable 300, the flange 4121 may be dislocated relative to the notch, and the situation that accurate clamping and fixing cannot be performed occurs, so that assembly personnel are required to take time to continuously rotate and adjust the unreeling adaptor; therefore, in order to ensure that one-time installation and positioning are successful, the foolproof positioning structure is also provided in the scheme.

Specifically, a fool-proof pin 4122 is fixedly arranged on the adapter shaft 412, and the fool-proof pin 4122 is positioned at one end close to the face plate 411; the fool-proof pin 4122 protrudes outward relative to the adapter shaft 412; meanwhile, a corresponding fool-proof notch 313 is arranged on the turntable 300; the cooperation of fool-proof pin 4122 with fool-proof slot 313 allows for positioning of unwind adaptor 400 for mounting on turntable 300.

It can be understood that, due to the design of the fool-proof positioning structure, when the unreeling adaptor 400 is mounted to the turntable 300, an assembler can visually make the fool-proof pin 4122 correspond to the fool-proof notch 313, so that the adaptor shaft 412 of the unreeling adaptor 400 can be smoothly inserted into the turntable 300, and the flange 4121 and the notch can be smoothly clamped and fixed.

In this scheme, the mandrel 200 and the turntable 300 need to be fixedly connected to form an integral body, so that rotation can be performed synchronously; the scheme is also designed on the connection structure of the two. Specifically, an outer ring cylinder shaft 312 is further arranged at one end of the turntable 300 facing the mandrel 200, and the outer ring cylinder shaft 312 surrounds the inner ring cylinder shaft 311; the two ends of the mandrel 200 are respectively sleeved and fixed with an outer ring cylinder shaft 312 of the turntable 300.

There are various ways of sleeving, for example, after sleeving the mandrel 200 on the outer ring shaft 312, fixing the mandrel and the outer ring shaft with nails; or the mandrel 200 and the outer ring barrel shaft 312 are fixedly connected in an interference fit manner; and a key groove is formed in the inner surface of the mandrel 200, a flat key is formed in the outer surface of the outer ring barrel shaft 312, and the flat key is matched with the key groove to realize fixed connection of the flat key and the key groove.

Considering that the winding roll formed after the mandrel 200 and the turntable 300 are fixed needs to wind the wire, the edge of the turntable 300 is gradually expanded during the winding process; thus, the disc surface of the whole winding disc is inclined outwards to deform, and the turntable 300 rubs against the inner wall of the box body 100, so that the smoothness of winding and unwinding is affected; thus, to avoid this, the turntable 300 is pre-provided in this embodiment as an inwardly pre-tilt configuration.

Specifically, referring to FIG. 2, the angle of the disk surfaces of two opposing turntables 300 with the central axis is α, 80- α -88. In this scheme the mode of pretilt can not cause the take-up reel to outwards incline deformation seriously.

Referring to fig. 8 to 9, in order to improve strength, stability of the whole device is ensured; here, a bracket 500 is also provided; specifically, the wire winding and unwinding device further includes a bracket 500 positioned on the inner wall of the case 100, and the bracket 500 is installed between the turntable 300 and the end plane of the case 100; the bracket 500 is abutted against the end plane of the case 100; the bracket 500 is provided with a circular sleeve 501 protruding and coaxial with the turntable 300; the turntable 300 is sleeved on the circular sleeve 501 and is in rotary fit.

Specifically, the bracket 500 includes a first support arm 511 and a second support arm 512 that are vertically disposed, and the circular sleeve 501 is disposed at the connection between the first support arm 511 and the second support arm 512; the end surfaces of the first support arm 511 and the second support arm 512 facing the case 100 are provided with positioning projections 513; corresponding positioning holes are arranged on the box body 100; the bracket 500 is detachably connected to the case 100 by a positioning engagement of the positioning projection 513 with the positioning hole.

It is actually easy to find that the support 500 in this embodiment has the same structure as the mandrel support mentioned in the initial embodiment (patent name: a wire output device; patent number: CN 213326023U), including the shapes of the first arm 511 and the second arm 512, the layout positions and the layout number of the positioning projections 513, and the like; and thus will not be described in detail herein.

However, it should be noted that, both the mandrel support of the initial solution and the support 500 provided in the present solution are "L" shaped; in other embodiments, the first arm 511 and the second arm 512 may also be disposed vertically such that the bracket 500 is in a "cross" shape; the circular sleeve 501 is also arranged at the junction of the first arm 511 and the second arm 512, i.e. at the centre of the cross-shaped bracket 500.
