Embodiment

Fig. 1 is the schematic diagram of a kind of bolt lock mechanism of one embodiment of the invention.Fig. 2 is the end view of the bolt lock mechanism of Fig. 1.Please refer to Fig. 1 and Fig. 2, bolt lock mechanism 100 is suitable for using on a device 200 (device 200 only illustrates the part).In the present embodiment, device 200 for example is a server.Device 200 can have a casing (not illustrating), but and the casing layering carry a plurality of bearing trays 210.

Bolt lock mechanism 100 comprises a framework 110, a sliding part 120, an ejector 130, leader 140 and a locating part 150.Framework 110 has a panel 112 and side plate 114, wherein the normal direction near normal of the normal direction of panel 112 and side plate 114 or vertical in fact.Sliding part 120 is disposed on the panel 112, and extends toward side plate 114.In other words, the shape of sliding part 120 is similar L shaped.

Ejector 130 is disposed between sliding part 120 and the panel 112, and the elastic force of ejector 130 is snapped in the hole clipping of casing side clamping part 122.Particularly, ejector 130 can be a helical spring, and clamping part 122 can be a trip.Therefore, the bearing tray 210 that disposes bolt lock mechanism 100 can make clamping part 122 engage with hole clipping by the elastic force of ejector 130, and then can be fixed on the casing.

Handle 140 is pivoted to panel 112, and handle 140 is articulated in one terminal 142 and sliding part 120 butts of panel 112.In the present embodiment, sliding part 120 can have a junction 126, and connecting portion 126 butt ends 142.The user can be the axle center with terminal 142 with handle 140, pivots with the direction away from side plate 114 with respect to panel 112, slides along a glide direction B with respect to panel 112 to drive sliding part 120, and then makes clamping part 122 move back card in hole clipping.At last, the user is pull handle 140 again, so that bearing tray 210 is pulled out on casing.

It should be noted that locating part 150 is disposed on the sliding part 120, in order to a limiting section 144 against the end 142 of handle 140.When sliding part 120 is subjected to the impulsive force F of moment in glide direction B is last because of extraneous collision, can slide along glide direction B after sliding part 120 is stressed, and locating part 150 can continue to slide along glide direction B with respect to panel 112 with limit slippage part 120 against limiting section 144.Therefore, against limiting section 144, clamping part 122 can keep being snapped in the hole clipping by locating part 150, and then keeps the fixed effect of bearing tray 210 and casing.

In the present embodiment, locating part 150 can have a sidewall 152, and sidewall 152 can be against limiting section 144.In addition, sliding part 120 can have a roof 124.Roof 124 has an angle theta with sidewall 152, and this angle theta for example is 90 degree.

Fig. 3 is the end view of a kind of bolt lock mechanism of another embodiment of the present invention.Please refer to Fig. 3, in the present embodiment, angle theta can be an acute angle.Specifically, sidewall 152 can extend to the top of the limiting section 144 of contiguous handle 140 relatively away from the outside of panel 112, and then limiting section 144 is caused restriction.

In sum, against limiting section, when sliding part was subjected to extraneous collision, limiting section can produce structural interference with the sidewall of locating part to bolt lock mechanism of the present invention by locating part, continued to slide along glide direction with respect to panel with the limit slippage part.Therefore, spacing to limiting section by locating part, clamping part can keep being snapped in the hole clipping, and then keeps bearing tray and the firm fixed effect of casing.

It should be noted that at last: above embodiment is only in order to technical scheme of the present invention to be described but not limit it, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement technical scheme of the present invention, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solution of the present invention.
