1. Field of the Invention
This present invention relates to an improved structure of slide rail latch for cabinet with simple composition, easy-to-assembly and dismantling applications
2. Description of the Related Art
Commonly, the structure of general fixed electronic devices (such as industrial computer, etc.), please refer to
Although the aforesaid technology of Patent No. M399583 can be achieved the purpose of assembly and dismantling for devices; however, due to the composition of the slide rail fixing frame is more complicated, it is difficult to manufacture all-in-one model. In addition, its complicated composition will also make its assembly process to become more difficult and time-consuming so as to fail to achieve the economic benefit of manufacturing and assembly; therefore, it needs further improvement.
In consideration of the fact that the slide rail latch structure has some operation defects and it has not yet achieved the most optimal design for its structure, this inventor started to research and develop the solution and hoped to make this present invention of an improved structure of slide rail latch for cabinet with more convenience in manufacturing and assembly and to conform to economic benefits in order to serve the public and advance the development in this industry.
This present invention is an improved structure of slide rail latch for device cabinet, which is composed of: at least one slide rail fixing frame with a locking plate on its front end. The locking plate is composed of a locking base plate with upper and bottom locking ends on both sides. This locking base plate is composed of at least one latching hole and one locking pin; as well as one latching fastener. This latching fastener includes one latching base plate with upper and bottom latch bending side edges on both sides, and this latching base plate is composed of at least one locking hook and locking hole which are correspondent with latching hole and locking pin respectively. This latch bending side edge includes a hook on its front end. As a result, this improved structure will make the fixing frame of slide rail to be simply and easily manufactured in all-in-one process, as well as more convenient and timesaving in assembly so as to actively upgrade the economic benefit for the assembly manufacturers.
Please refer to -shape frame). In addition, a containing space is composed of the same-direction bending side (52) and the inside of base plate (51) (not showed in drawing), which the space can be contained at least one side of the slide rail set (70). The slide rail set (70) is orderly composed of bottom rail (71) and correspondent upper rail (72) (in this present invention, the slide rail set is a dual-rail type, but anyone who is familiar to such technique can replace with actual and exact model types). One end of the bottom rail (71) is equipped with fixing holes (711). The upper rail (72) can be fixed with electronic devices (not showed in drawing). And the base plate (51) is equipped with trench hole (51a) and fixing hole (51b). The slide rail set (70) can be fixed on the base plate (51) by using the fixing hole (711) and (51b). Moreover, one locking plate (53) is installed on the front end of the base plate (51). One slanting plate (54) is connected between the locking plate (53) and the base plate (51), and its side showed as a bevel edge (541). The locking plate (53) is equipped with one locking base plate (55). Locking ends (56) that perpendicularly bent toward the same direction are installed on the locking base plate (55) (in this present invention, it showed as a
-shape frame). One locking space (530) is composed of the locking ends (56) and the inner side of the locking base plate (55); in addition, this locking base plate (55) is equipped with one latching hole (552) and its correspondent locking pin (551). The locking end (56) on the correspondent sides of the front end locking base plate (55) is recessed inwardly and equipped with one blocking plate (57). One thread hole (571) is installed on the blocking plate (57). These 2 inward-recessed sides on the front end of the locking base plate (55) are connected to the locking end (56) with using the connecting plate (553).
The latching fastener (60) includes one latching base plate (61). The upper and bottom sides of the latching base plate (61) are respectively equipped with the latch bending side edges (62) that perpendicularly bent toward the same direction. The latch bending side edges (62) are forwardly stretched from the latching base plate (61). The latching base plate (61) is equipped with pairing locking holes (611), and one recessed part (612) at the central part of the front end. One locking hook (613) is installed on the bending part of this recessed part (612). The latch bending side edge (62) is equipped with one shallow trench (621), and this latch bending side edge (62) is stretched from the shallow trench (621) forwardly to form a hook plate (63) which is perpendicularly bent inward. The front end of this hook plate (63) is quipped with a hook (631); therefore, the shallow trench (621) is used to make better flexibility for this hook plate (63) so as to facilitate the latching and loosing operations of this hook (631).
