Abstract

Disclosed is a carrying mechanism of an optical read-write head with a small mechanism, comprising four rod seats integrated with the small mechanism, both ends of two slide rods are in nested connection with two pairs of opposite containing grooves in the rod seats, the two slide rods are in nested connection with the two sides of the seat body of the optical read-write head which can slide back and forth on the two slide rods, an elastic sheet which can elastically contact and resist to the slide rod is arranged on the rod seats and the rod seats are integrally formed.

Description

The load carrier of small movement optical read/write head

Technical field

The utility model is relevant with CD-ROM device, especially relates to the load carrier of a kind of small movement optical read/write head in the CD-ROM device.

Background technology

General CD-ROM device is provided with optical read/write head, reading the data in the CD-RW discsCD-RW, or data is write in the CD-RW discsCD-RW.See also Fig. 1, Fig. 2, the small movement (traverse) 10 of general CD-ROM device is combined with three adjustable pole sockets (Bar holder), 20 and one fixed pole socket 21; Optical read/write head pedestal (pickup head) 12 both sides of one optical read/write head (optical pickup) 11 are socketed on slide bar 13 respectively, can move around on two slide bars (bar) 13, make the data of optical read/write head 11 read-write its top CD-RW discsCD-RW; The two ends of this two slide bar 13 are socketed on fixed pole socket 21 itself and corresponding adjustable pole socket 20 respectively; This adjustable pole socket 20 (seeing also Fig. 2) is to comprise that top board 22, following 23 and spring 24 form; Following seat 23 has an accommodation chamber 231 and a perforate, for ccontaining this spring 24 and socket slide bar 13; It is the both sides that are locked in small movement 10 with a set bolt 25 that this top board 22 reaches following 23; One adjusts bolt 26 top board 22 that is spirally connected, and penetrates down ejection slide bar 13 walls in the accommodation chamber 231 of seat 23, with the height of adjustment slide bar 13.Be combined with rotating disk (turn table) 14 (seeing also Fig. 1) on this small movement 10 in addition to drive the CD-RW discsCD-RW rotation, utilize and adjust the height that bolt 26 is adjusted 20 socket slide bars 13 of three adjustable pole sockets, with the depth of parallelism of adjusting optical read/write head 11 and the height that arrives rotating disk 14 thereof; Above-mentioned adjustable pole socket 20 needs ccontaining slight spring 24, and assembling very is not easy, also cost of idleness, and the disappearance for the load carrier that improves above-mentioned known small movement optical read/write head proposes the utility model.

The utility model content

Fundamental purpose of the present utility model provides a kind of load carrier of small movement optical read/write head, can reduce number of parts, has reduced the demand to the machine parts'precise degree, and assembling easily, has reduced cost.

For achieving the above object, the utility model provides a kind of load carrier of small movement optical read/write head, comprises that optical read/write head pedestal both sides are socketed on respectively on each slide bar; Each pole socket of the adjacent socket respectively in the two ends of this two slide bar; Pole socket combines with small movement; It is integrated having a pole socket in the pole socket at least; This integrated pole socket is provided with a shell fragment, and is provided with a storage tank and an opening in this shell fragment adjacent, for the end of inserting slide bar.

The load carrier of small movement optical read/write head, wherein integrated pole socket combines with a set bolt with small movement.

The load carrier of small movement optical read/write head, wherein this integrated pole socket and small movement are integrated.

The load carrier of small movement optical read/write head, wherein this small movement is spirally connected and one adjusts bolt; This adjustment bolt stretches into the interior ejection slide bar wall of storage tank of this integrated pole socket, adjusts the height of slide bar.

Embodiment

See also Fig. 3, the utility model small movement 30 is in conjunction with four pole sockets 40; One optical read/write head pedestal, 32 both sides are socketed on respectively on the slide bar 33; The two end portions of this slide bar 33 is socketed on pole socket 40 respectively.

See also Fig. 4, Fig. 5, pole socket 40 of the present utility model is integrated, and its top is provided with a shell fragment 41, and these shell fragment 41 belows (adjacent) are provided with a storage tank 42 and an opening 43, for inserting slide bar 33 (seeing also Fig. 5).

One set bolt 44 is fixed in pole socket 40 on the small movement 30; And use one to adjust bolt 45 small movement 30 that is spirally connected, and and stretch into ejection slide bar 33 walls in the storage tank 42, to adjust the height of slide bar 33, make optical read/write head 31 keep distance and the depth of parallelism (see also Fig. 3) suitable with rotating disk 34.

See also Fig. 6, when pole socket 40 is made comparatively accurately, pole socket 40 of the present utility model need not utilize the adjustment bolt that the height seat of slide bar 33 is further adjusted, and can directly slide bar 33 be placed the upper limb 431 of opening 43, utilizes shell fragment 41 elasticity compacting slide bar 33 to get final product.

Pole socket 40 of the present utility model is with integrated shell fragment 41, replaces the required spring 24 of known as shown in Figure 2 adjustable pole socket 20, thus can reach the purpose that reduces number of parts, reduces cost, but and ease of assembly.

In two pole sockets 40 at the utility model slide bar 33 two ends, an available fixed pole socket replaces one of them pole socket 40; Also can reach the effect of adjustable pad.Pole socket 40 of the present utility model also can with movement 10 one-body molded making, more can save the cost of assembling.

The above record only for utilizing the embodiment of the utility model technology contents, anyly is familiar with modification that this technology utilization the utility model does, variation, all belonged to the claim of the utility model opinion, and be not limited to present embodiment.
