Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the attached drawings.

Referring to fig. 1-2, an embodiment of the present invention provides a multi-screen display connection data line for a computer, including a housing 1, the housing 1 is rotatably connected with a wire spool 7, the wire spool 7 is wound with a wire 2, one end of the wire 2 passes through a central axis of the wire spool 7 to the housing 1, and the other end of the wire passes through the peripheral side of the housing 1.

Be provided with spiral spring 8 on wire reel 7, spiral spring 8's one end fixed connection is on wire reel 7's center pin, other end fixed connection is on casing 1, coaxial fixedly connected with ratchet 5 on wire reel 7, casing 1's inside elastic rotation is connected with pawl 6, pawl 6 cooperatees with ratchet 5, it is specific, the cover is equipped with the torsional spring in pawl 6's the pivot, the one end fixed connection of torsional spring is on casing 1, other end fixed connection is on pawl 6, drive ratchet 5 and pawl 6 joint when spiral spring 8 resumes elastic deformation, fixedly connected with poking rod 3 on pawl 6, arc wall 4 has been seted up on the all sides of casing 1, poking rod 3 keeps away from the one end of pawl 6 and passes arc wall 4 and extends to the outside of casing 1, poking rod 3 along arc wall 4 and in order to drive pawl 6 rotation and break away from the ratchet of ratchet 5, it is specific, pawl 6 rotates through the pivot and connects on casing 1, pivot and casing 1 fixed connection, pawl 6 rotates with the pivot and is connected, pawl 6 rotates through the pivot and is connected on casing 1, pawl 6 and pivot fixed connection.

Furthermore, a plurality of baffles 9 are fixedly connected to the housing 1, the baffles 9 are distributed on the periphery of the wire spool 7 in an annular array, and the baffles 9 are arranged to prevent the wire 2 from being unevenly contracted when the wire 2 is contracted and to prevent the wire from being separated from the wire spool 7.

Further, the host computer of computer is connected to line body 2 one end, and the display screen of computer is connected to the other end, through host computer and the display screen that line body 2 connects for the display screen lights.

The working principle is as follows: when the display screen and the host need to be connected, the wire body 2 penetrating from the peripheral side surface of the shell 1 is pulled, so that the wire body 2 is pulled, the wire winding disc 7 is driven to rotate along the first rotating direction when the wire body 2 is pulled, meanwhile, the volute spiral spring 8 is further elastically deformed, the wire winding disc 7 drives the ratchet wheel 5 to synchronously rotate, the ratchet wheel of the ratchet wheel 5 drives the pawl 6 to rotate, so that the ratchet wheel slides over the pawl 6 smoothly, the ratchet wheel 5 and the wire winding disc 7 can both rotate along the first rotating direction smoothly, when the wire body 2 pulled out of the shell 1 reaches the required length, the volute spiral body 2 is stopped being pulled, at the moment, the elastic force of the spring 8 has the tendency of driving the wire winding disc 7 and the ratchet wheel 5 to rotate along the direction opposite to the first rotating direction, but due to the matching of the pawl 6 and the ratchet wheel 5, the pawl 6 is clamped into the ratchet wheel of the ratchet wheel 5, the rotation of the ratchet wheel 5 in the direction opposite to the first rotating direction is stopped, the volute spiral coil 5 and the wire body 7 and the volute spiral coil 7 overcome the elastic force of the spring 8 and do not rotate along the direction opposite to rotate, so that the length of the wire winding wheel 2 is fixed and the length of the display screen is matched, and the length of the host is matched. When the released line body 2 needs to be rolled, the poke rod 3 is poked, the poke rod 3 overcomes the elastic torsion force (namely the elastic force of the torsion spring) of the pawl 6, meanwhile, the ratchet wheel 5 can rotate to a first rotation direction by a small angle, so that the elastic force of the volute spiral spring 8 also needs to be overcome, so as to realize the ratchet that the pawl 6 is rotated to be separated from the ratchet wheel 5, at the moment, the ratchet wheel 5 and the wire winding disc 7 can rotate to roll the released line body 2 under the elastic force action of the volute spiral spring 8, thereby playing the effect of storing the line body 2, and being very portable.
