[0020] Before the present invention is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.
[0021] See also Figure 1 and Figure 2 An embodiment of a telescopic rail fixing device 10 of the utility model is suitable for fixing a rail 1 between a rear end and a front end of a cabinet (not shown), wherein the rail 1 includes an outer rail 11, a middle rail 12 disposed on the outer rail 11, and an inner rail 13 disposed on the middle rail 12. The telescopic rail fixing device 10 includes a rear support unit 2 and a front support unit 3.
[0022] See also Figures 2 to 4 The rear support unit 2 is suitable for connecting the rear end, and includes a rear bracket 21 suitable for connecting the rear end, a rear support rail 22 fixedly connected to the rear bracket 21, a base 23 fixedly arranged on the rear support rail 22, an elastic member 24 arranged on the base 23, and a push member 25 movably arranged on the base 23. The rear support rail 22 forms a first stopper 221 and a second stopper 222 spaced from the first stopper 221. The base 23 has a flat plate portion 231 arranged on the rear support rail 22 and a protruding portion 232 protruding from the flat plate portion 231, the protruding portion 232 defines a receiving groove 233 for the elastic member 24 to be arranged, and has a first end 232a facing the rear end for abutting one end of the elastic member 24 and a second end 232b opposite to the first end 232a. The base 23 also has a guide groove 234 extending from the second end 232b toward the first end 232a and communicating with the receiving groove 233. The first stopper 221 can stop the base 23 from moving toward the rear end. The elastic member 24 is a compression spring, but is not limited thereto. The push member 25 is movably disposed in the receiving groove 233 and abutted by the other end of the elastic member 24, and includes a main body 251 located in the receiving groove 233 and abutting against the other end of the elastic member 24, and a guide protrusion 252 protruding from the main body 251 and movably disposed in the guide groove 234. The elastic member 24 is very convenient to install. One end of the elastic member 24 only needs to be abutted against the first end 232a of the protrusion 232, and the push member 25 is then installed into the accommodating groove 233 and the guiding groove 234 for the other end of the elastic member 24 to abut against. The base 23 generally covers the elastic member 24, which can play a role in protecting, guiding and preventing it from falling off.
[0023] See also Figure 2 , Figure 3 and Figure 5The front support unit 3 includes a front support rail 31 movably disposed on the rear support rail 22 and adapted to be fixedly connected to the slide rail 1, and a front bracket 32 adapted to be connected to the front end and one end of the slide rail 1. The front support rail 31 has a joint surface 311 facing the base 23, a mounting surface 312 opposite to the joint surface 311, a push-resistance block 313 formed on the joint surface 311, and a clamping block 314 formed on the joint surface 311 and spaced from the push-resistance block 313. The push-resistance block 313 abuts against the guide protrusion 252 of the push-resistance member 25.
[0024] See also Figure 2 , Figure 6 and Figure 7 The front support rail 31 can move toward the rear support rail 22, driving the slide rail 1 and the front bracket 32 to move toward the rear support rail 22, so as to change the distance between the front bracket 32 and the rear bracket 21 (i.e., the rear end of the cabinet), and adjust the overall length of the telescopic slide rail fixing device 10, so that it can be suitable for cabinets of various lengths and sizes (not shown). The second stopper 222 can stop the clamping block 314 to prevent the front support rail 31 from continuing to move toward the rear support rail 22. Figure 7 The push-stop block 313 abuts against the guide protrusion 252 to drive the main body 251 to push and compress the elastic member 24, so that the elastic member 24 exerts an elastic restoring force on the front support rail 31, the outer rail 11 of the slide rail 1 and the front bracket 32, and the front bracket 32 can be tightly connected to the front end, so that the telescopic slide rail fixing device 10 can be more firmly connected to the cabinet.
[0025] In summary, the telescopic rail fixing device 10 of the utility model can move toward the rear support rail 22 by means of the front support rail 31, driving the rail 1 and the front bracket 32 to move toward the rear support rail 22, so as to change the distance between the front bracket 32 and the rear end of the cabinet, and adjust the overall length of the telescopic rail fixing device 10, so that it can be suitable for cabinets of various lengths and sizes. And by means of the elastic member 24 applying an elastic restoring force to the front support rail 31, the front bracket 32 can be closely connected to the front end, so that the telescopic rail fixing device 10 can be more firmly connected to the cabinet, so that the purpose of the utility model can be achieved.
