- the outer rotating shaft can be made of plastic, and the central shaft can be more to withstand strong tension and finer diameter. Made of metal.
- the bottom end of the protective sheet 6 is integrally formed with a circular lower turntable cover 82.
- the lower dial cover 82 is provided with a lower recess 82_1, and the bottom end of the turntable 3 has a lower flange 33 that matches the lower recess 82_1 of the lower dial cover 82. After the mounting, the lower flange 33 of the turntable 3 is inserted. In the lower recess 82_1 of the turntable cover 82, the lower turntable cover 82 is fastened to the bottom end of the turntable 3, and the protective sheet 6 is fixed to the outer side of the turntable 3.
- a retaining portion 61 for engaging the flexible circuit board 10 is formed between the guard 6 and the turntable 3, and the lower turntable cover 82 is further provided with a lower circular hole 82_2 through which the lower central shaft 52 passes.
- the top of the turntable 3 is fastened with an upper turntable cover 81, and the upper turntable cover 81 is provided with an upper groove 81_1.
- the top end of the turntable 3 and the top end of the protective cover 6 are convexly matched with the upper groove 81_1 of the upper turntable cover 81.
- the upper flange 97, in the mounting cymbal, the upper flange 97 of the turntable 3 is inserted into the upper groove 81_1 of the upper turntable cover 81.
- the outer diameter of the upper turntable cover 81 and the outer diameter of the lower turntable cover 82 are slightly smaller than the inner diameter of the outer casing.
- the above structure has the following advantages: 1.
- the turntable 3 and the guard 6 are two separate components, so that the guard 6 can be freely removed, which is easy to assemble and can be avoided.
- the plastic injection technology has not been able to overcome the deep and narrow mold draft space precision, and relatively large space for the turntable 3 can be obtained, and the operation of the flexible circuit board 10 on the outer surface of the turntable 3 can be made easier.
- independent turntable 3 and guard 6 so that the functional requirements of the turntable 3 become a single ring structure because of the purpose of simply placing the scroll spring, so the turntable 3 becomes stronger without being caused by the internal scroll spring Deformation or deformation.
- the middle portion of the turntable 3 is provided with a circular through hole 34, and the through hole 34 communicates with the center of the upper receiving area 31 and the center of the lower receiving area 32.
- the bottom end of the center shaft 51 is placed in the top of the through hole 34, the top end of the lower center shaft 52 is placed in the bottom of the through hole 34, and the upper central shaft 51 is provided with an inner portion for catching the upper scroll spring 41.
- the card slot 98 at the center end and the upper portion of the turntable 3 are provided with a card position 99 for catching the outer end of the upper scroll spring 41.
- the lower central shaft 52 is provided with a card slot 98 for catching the inner center end of the lower scroll spring 42.
- a lower portion of the turntable 3 is provided with a card seat for catching the outer end of the lower scroll spring 42 99.
- the upper central shaft 51 and the lower central shaft 52 are on the same vertical straight line to form the rotating shaft of the turntable 3, and therefore, the turntable 3 can smoothly rotate about the rotating shaft formed by the upper central shaft 51 and the lower central shaft 52.
- the outer casing formed by the left casing 2_1 and the right casing 2_2 of the present embodiment is a closed casing, and the closed casing has a cylindrical shape, so that the entire reeling device has a rounded shape, Conducive to smooth sliding in the narrow and limited space of the server chassis and other products, and avoid the collision or blockage in the chassis caused by the forward or backward linear motion of the design module product, reducing the possibility of interference on the internal components of the chassis .
- the assembly process of this embodiment is as follows: First, the upper scroll spring 41 is placed in the upper accommodating area 31 of the turntable 3, and the lower scroll spring 42 is placed in the lower accommodating area 32 of the turntable 3, and the upper vortex is turned on. The outer end of the coil spring 41 catches the latching position 99 at the upper portion of the turntable 3, and the outer end of the lower scroll spring 42 catches the latching position 99 at the lower portion of the turntable 3. Then, the flexible circuit board 10 is placed on the outer side of the turntable 3, and then fastened.
- the left casing 2_1 and the right casing 2_2 are fastened and fixed, and one end of the flexible circuit board 10 is passed out from the outlet 91 of the left casing 2_1, and the other end is Passing out from the outlet 91 of the right casing 2_2; Rotating the shaft piece 71 and the lower outer rotation shaft piece 72, screwing the upper scroll spring 41 and the lower scroll spring 42, inserting the upper positioning post 93 into the upper positioning hole 94, and the lower positioning post 95 is inserted into the lower positioning hole 96. , that is, the assembly is completed.
- the flexible circuit board 10 In the initial state, the flexible circuit board 10 is wound around the periphery of the turntable 3; when the flexible circuit board 10 is required to be pulled out, one or both ends of the flexible circuit board 10 can be Pulling, the flexible circuit board 10 can be stretched to make the flexible circuit board 10 in an extended state; then, as long as it is placed or rotated with the turntable 3, the turntable 3 will be in the upper scroll spring 41 and the lower scroll spring.
- the rolling elastic force of 42 is rotated to rewind the flexible circuit board 10 to the periphery of the turntable 3, returning to the initial state, and the flexible circuit board 10 is automatically wound up.
- Embodiment 2 differs from Embodiment 1 in that: a left and right closed housing structure is adopted, and no pillar is required; in addition, an upper outer rotating shaft piece 71 and a lower outer rotating shaft piece 72 are added.
- the turntable 3 can be turned from the outside.
