When assembled, the plate-like side wing portion 122 is slidably engaged in the rail portion 222, so that the side wing portion 122 can move along the aforementioned rail portion 222, and the aforementioned protrusion 2220 can be formed with the side wing portion 122. In the present embodiment, the rear end portion 121B of the body 121 of the latching member 12 is more connectable to an elastic portion 124; the body 121 of the latching member 12 The front end portion 121A is formed with a pressing portion 125. Specifically, the elastic portion 124 can be integrally formed on the rear end portion 121B of the body 121 of the latching member 12. For example, the elastic portion 124 can be an annular structure formed by bending a plastic member, and the two ends 1240 are integrally formed. The intermediate portion 1241 of the plastic member is connected to the body 22, and the intermediate portion 1241 can be a bent panel, and the body is connected to the body portion 1242 of the body member 12, as shown in FIG. 2A. A hole 2200 corresponding to the above-mentioned insert can be opened on the side wall 220 of the second surface 220, and the above-mentioned abutting effect can be achieved by using the combination of the insert and the hole 2200, but not limited thereto.

In addition, the first tongue portion 221 has corresponding two extending protrusions 2212. In other words, the two extending protrusions 2212 are formed in pairs on both sides of the first tongue portion 221, preferably, the two extending protrusions The position of the 2212 is close to the free end of the first tongue 221; and the body 121 of the latching member 12 has a sliding slope 123 corresponding to the two extending protrusions 2212. Specifically, the sliding slope 123 is front high and low. The slanting surface (defined along the direction of the disk drive 21), the extending protrusion 2212 preferably has a curved surface structure. For example, in the embodiment, the two sides of the first tongue portion 221 are respectively bent and extended to extend the platform 2210. The extending protrusion 2212 is an annular convex structure disposed on the extending platform 2210, and the outer edge of the annular protruding structure is slidable along the sliding inclined surface 123.

When the user wants to mount the disk drive 21 in the body 22, the disk drive 21 only needs to be pushed into the body 22, and during the pushing process, the fixing member 11 on the side wall 210 of the disk drive 21 is pushed. The fixing protrusion 2211 on the first tongue portion 221 is squeezed (but the interference amount is small, and the slippage of the latching member 12 is not caused). When the fixing hole position 111 of the fixing member 11 corresponds to the fixing protrusion 2211, The fixing protrusion 2211 is slid into the fixing hole 111 of the fixing member 11 to form a locking state to achieve the effect of fixing the disk drive 21 in the body 22. Referring to FIG. 2C, the fixing protrusion 2211 preferably has a stopping surface 22111 for blocking the inner side wall of the fixing hole 111, so that the disk drive 21 is more stably installed in the body 22.

When the user needs to take out the disk drive 21 installed in the body 22, the pressing portion 125 of the latching member 12 can be applied, so that the body 121 of the latching member 12 is in the direction of the arrow shown in FIG. That is, sliding toward the rear of the body 22, and when the body 121 of the latching member 12 slides, the extended convex portion 2212 of the first tongue portion 221 is moved from the lower position of the sliding slope 123 (ie, the rear end of the sliding slope 123). Movement along the sliding slope 123 of the latch member 12 moves to a higher position on the sliding ramp 123 (i.e., the leading end of the sliding ramp 123) (the position of the extended projection 2212 changes as shown in Figs. 4 and 4A) Therefore, when the annular protrusion of the extending convex portion 2212 moves along the sliding inclined surface 123, the free end of the first tongue portion 221 is moved up in a direction away from the disk drive 21, and at this time, the first tongue portion 221 The fixing protrusion 2211 can be disengaged from the fixing hole 111 on the fixing member 11 (as shown in FIG. 4B), so that the disk drive 21 is no longer held on the side plate member 220 of the body 22, and the user can drive the disk unit. 21 pulled out.

When the user wants to pull out the disk drive 21, the user applies a force to cause the body 121 of the latch member 12 to slide toward the rear of the body 22, thereby causing the deformation of the elastic portion 124 (ie, the compression of the elastic portion 124). (as shown in FIG. 4A), when the user slightly removes the disk drive 21 to release the fixing hole 111 on the fixing member 11 from the projection 2211, the force application state can be released and the disk drive 21 can be completely taken out. The user can directly remove the disk drive 21 and then release the force application state. When the user releases the force, the body 121 of the latch member 12 can be returned to the starting position by the elastic restoring force of the elastic portion 124 (as shown in FIG. 2A). In short, when the user applies the force to the pressing portion 125 to push the body 121 of the latching member 12 to move, the elastic portion 124 generates elastic deformation in a compressed form, and when the user ends the applying force, the elastic portion 124 recovers. The force can reversely push the body 121 of the latch member 12 back to the starting position. However, the present invention does not limit the position, shape, and type of the elastic portion 124. For example, the elastic portion 124 may be a spring, a spring, or the like.

On the other hand, in order to avoid the problem that the free end of the first tongue portion 221 cannot be completely restored to the starting position, the inner side of the body 121 of the latching member 12 is further provided with a rib 126 (as shown in FIG. 3A), and the first The tongue portion 221 has an auxiliary projection 2213 (shown in FIG. 1D) corresponding to the rib 126, which is formed by the outer surface of the side panel member 220 of the body 22 protruding away from the inside of the body 22. Specifically, a rib 126 is formed on the inner side of the body 121 of the latching member 12, and is formed along the longitudinal direction defined by the front end portion 121A and the rear end portion 121B of the body 121 of the latching member 12, when used. When the force is applied, the restoring force of the elastic portion 124 pushes the body 121 of the latching member 12 back to the starting position, and the rib 126 disposed on the inner side of the body 121 can be auxiliary with the outer surface of the body 22. The bump 2213 generates interference. More specifically, the rib 126 may have a front low and a high interference slope 126A and an interference top edge 126B extended by the interference slope 126A, and the interference top edge 126B is provided with a limiting groove 126C. The position of the interference slope 126A and the interference top edge 126B is recessed in the body 121, and the interference slope 126A of the rib 126 during the process of the body 121 of the latch member 12 sliding back to the starting position. The top edge 126B will sequentially abut the surface of the auxiliary bump 2213 (the interference slope 126A can improve the smoothness of the rib 126 and the auxiliary bump 2213 to slide) to completely push the first tongue 221 back. In the initial position, the limiting groove 126C preferably provides the top end of the auxiliary bump 2213. In order to avoid the situation that the subsequent disk drive 21 cannot be stably installed; similarly, when the disk drive 21 is mounted in the body 22, the rib 126 can be complemented by the auxiliary convex portion due to the structure of the interference slope 126A and the interference top edge 126B. The block 2213 forms an interference state to press the first tongue 221 to assist in clamping the fixing protrusion 2211 to the fixing hole 111. In other words, in the embodiment, the rib 126 on the latching member 12 can be first The auxiliary bumps 2213 on the tongue 221 are matched to improve the stability of the mounting disk drive 21.

Further, in conjunction with FIG. 2A and FIG. 2C, the body 22 is further provided with a second tongue portion 223 corresponding to the front end portion 121A of the latching member 12, and the second tongue portion 223 is substantially disposed at the front end of the latching member 12. The front end of the 121A allows the free end of the second tongue 223 to act as a stop for the latching member 12. Specifically, the free end of the second tongue 223 can be provided with a blocking projection 2231. When the body 21 is mounted in the body 22, the free end of the second tongue portion 223 is pressed by the side wall of the disk drive 21 to avoid displacement of the free end of the second tongue portion 223 toward the inside of the body 22, and the second tongue portion The blocking projection 2231 on the free end of the 223 can be used to stop the front end portion 121A of the latching member 12, so that the latching member 12 can be prevented from slipping forward and falling off, and the reliability of the mounting assembly of the present invention can be ensured.

The body 22 can be provided with a card slot 225 (shown in FIG. 1). When the disk drive 21 is mounted on the body 22 without using the aforementioned fixing member 11, the unused fixing member 11 can be temporarily It is detachably mounted on the card slot 225 (as shown in FIG. 1C) to avoid the problem of the fastener 11 being lost. Preferably, the card slot 225 is formed on the upper plate member 226 of the body 22. When the disk drive 21 is to be mounted, the fixing member 11 is removed from the card slot 225 and mounted on the disk drive 21.

In summary, the present invention utilizes the mounting assembly of the fixing member 11 and the latching member 12 for the purpose of mounting an extracting device (for example, the disk drive 21) to a body (for example, the body 22 of the computer casing). It should be noted that the thickness of the fixing member 11 of the present invention is within a predetermined range, preferably not more than 1 mm. For example, the fixing member 11 is a metal plate member, so that the fixing member 11 is installed on the disk drive. 21, the disk drive 21 can be directly inserted into the casing 3 from the card slot 30 outside the body 22 (the casing 3 is covered by the outer cover 31 of the body 22) (as shown in FIG. 5). In order to disassemble the outer cover 31 of the casing 3, the disk drive 21 can be placed in the body 22 held by the casing 1, and the fixing member 11 can be assembled by using the screw holes inherent in the disk drive 21. On the disk drive 21, it is not necessary to manufacture the disk drive 21 of a special specification. In other words, the mounting assembly of the present invention can be applied to the current system without the need to manufacture the disk drive 21 and the body 22 of a special size. In the above embodiment, the body 22 is a frame provided in a computer case. In another variant embodiment, the body 22 can also be a complete casing (or casing) having the structure of the outer cover 31 described above, and the latching member 12 of the present invention can be externally mounted to the panel of the casing.
