Abstract

The utility model relates to a moving fixing mechanism for optical-path apparatus, which comprises a casing, a sliding block and an elastic press key. One side of the casing is provided with an opening, and the sliding block can slide between a first position and a second position of the opening, wherein, the inner part of the sliding block is connected with a fastening element. When the sliding block slides to the first position, the fastening element can be fastened with the optical-path apparatus. The elastic press key comprises a press key part, a clamping and fastening part and a reset element. The press key part is projected out of the outside of the sliding block by the action of the reset element, and the fastening of the clamping and fastening part and the casing is controlled by the pressing of the press key part.

The optical-path apparatus is not fixed by that the pressing of the press key part makes the sliding block move to the second position of the opening to cause the fastening element of the sliding block and the optical-path apparatus to be separated.

Description

The mobile fixed mechanism of optical path device

The utility model is the mobile fixed mechanism about a kind of optical path device, refers in particular to a kind of fastening effect that utilizes buckling element and optical path device, to reach the mobile fixed mechanism that optical path device is fixing.

In daily life, scanner has become and a kind ofly can not obtain scarce computer peripheral and be equipped with, its main function is that the optical path device by scanner inside picks up document image, and be delivered to computer again carrying out image processing, so optical path device can be described as most important element in the middle of the scanner inside.The destruction of causing its inner optical path device because being subjected to the vibrations of external force for fear of scanner; on the casing of scanner, can be provided with mobile fixed mechanism usually; this mobile fixed mechanism can be fixed in optical path device on the casing, destroys in handling process to avoid scanner.

See also shown in Figure 1ly, it is the mobile fixed mechanism synoptic diagram of the optical path device of known technology.This mobile fixed mechanism 10 comprises a casing 12, one bolt 14 and a fastener 16 (not shown), these casing 12 inside are provided with light path and scan the path and make optical path device 20 can be placed in casing 12 inside, and scan the image scanning that file is carried out in the path along this light path, see also shown in Figure 2, this casing 12 has a circular hole 121 its inside and is provided with internal thread on the one side, this bolt 14 comprises a nut 141, an one spiral shell body 142 and a spiral shell end 143, wherein this nut 141 surface of being provided with flat recess 144 and this spiral shell body 142 is provided with external thread, this fastener 16 is for elongate structure and have a buckling parts 161, this fastener 16 be fixed on the spiral shell end 143 and this bolt 14 and fastener 16 vertical mutually, therefore fastener 16 also can rotate together with bolt 14 when bolt 14 rotates.When this fastener 16 turns to primary importance, this buckling parts 161 can fasten optical path device 20 live, when this fastener 16 turns to the second place, this buckling parts 161 separates with optical path device 20, make optical path device 20 can carry out image scanning, known technology is to utilize above-mentioned mode to reach the purpose that optical path device 20 is fixed.Because optical path device 20 can be got back to the reference position that scans after scanning usually finishing file, therefore the mobile fixed mechanism 10 of known technology normally is located near the reference position, the mobile fixed mechanism 10 of known technology is described as follows optical path device 20 fixing embodiments, at first optical path device 20 is moved to initial location, rotating bolt 14 and fastener 16 rotated to primary importance afterwards, buckling parts 161 when fastener 16 rotates to primary importance on it will fasten optical path device 20, and this optical path device 20 will can't move because of being fixed this moment; Scan if optical path device 20 will be untied to carry out file again, its embodiment is rotating bolt 14 and fastener 16 is rotated to the second place, when fastener 16 rotates to the second place, buckling parts 161 on it will separate with optical path device 20, and this moment, this optical path device 20 can scan scanning the enterprising style of writing part in path.Yet, the mobile fixed mechanism 10 of the optical path device 20 of known technology has following shortcoming: (a) the mobile fixed mechanism 10 of known technology is when rotating bolt 14, preparation tool (for example coin) places flat recess 144 rotating bolt 14 again on the nut 141 in addition, and is higher for the degree of difficulty of its operation of user.(b) to take the volume of casing 12 inside bigger for the mobile fixed mechanism 10 of known technology, because bolt 14 is elongate structure and vertical mutually with fastener 16, so will take bigger space, casing 12 inside.(c) mobile fixed mechanism 10 its surface structures of known technology are comparatively complicated, and modularity is difficult for, and casing 12 is restricted in the design of external form.(d) the mobile fixed mechanism 10 of known technology must be provided with internal thread by circular hole 121 on casing 12, and on spiral shell body 142 surfaces of bolt 14 external thread is set, and not only makes to go up than complexity and fit on also comparatively to bother.

Fundamental purpose of the present utility model is to provide a kind of simple structure, volume is little and the mobile fixed mechanism of easier optical path device is gone up in operation, with shortcomings such as the complex structure that mobile fixed mechanism was had, the volume that improve known technology are big and not easy to operate.

The mobile fixed mechanism of the utility model optical path device comprises a casing, one slide block and a flexible keypad, this casing is provided with opening on the one side, this slide block can be at first of opening, slide between the second place, wherein this slide block within it side be connected with a buckling element, when this slide block slides into primary importance, buckling element can be interlocked with optical path device, this flexible keypad comprises a button portion, one holding section and a reposition element, this button portion protrudes in side outside the slide block by the effect of reposition element, and the fastening between holding section and casing is controlled by pushing of button portion, being fixed as through pushing of button portion of optical path device makes slide block move to the primary importance of opening, cause the buckling element and the optical path device of slide block to be interlocked, it is to see through pushing of button portion to make slide block move to the second place of opening that the static solution of optical path device removes, and causes the buckling element of slide block to separate with optical path device.
