Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Please refer to fig. 1-4, in the embodiment of the present invention, an embodiment of the present invention provides a guide rail type spring device for a hinge, including a spring main body 1, the spring main body 1 is integrally installed in a spring sleeve 2, the spring sleeve 2 is a sectional type cylinder body with a telescopic gap 20 at the middle part, a plurality of guide rail cavities 21 are installed on the side wall of the spring sleeve 2 at both sides of the telescopic gap 20, a limit guide rail 22 for connecting the spring sleeve 2 at both sides of the telescopic gap 20 is slidably installed in the guide rail cavities 21, and the outer side wall of the spring main body 1 is slidably connected with the inner cavity wall of the spring sleeve 2.
The guide rail cavity 21 is arranged in the same direction as the stretching direction of the spring body 1, the sliding direction and angle of the spring body 1 in the spring sleeve 2 are mainly ensured to be consistent with the sliding direction and angle of the limit guide rail 22, and the limit guide rail 22 can play a good role in guiding and limiting when the spring body 1 stretches.
The length of limit guide 22 is greater than the width of flexible breach 20 and the biggest extension length of spring main part 1 sum, mainly guarantee that spring main part 1 is when being stretched to the biggest deformation volume, the spring sleeve 2 of the flexible breach 20 left and right sides can be widened flexible breach 20 to both sides, meanwhile, the limit guide 22 that slides and wear to establish in guide chamber 21 leaks back, in order to prevent that arbitrary one end from sliding out in guide chamber 21 about limit guide 22, here need set up long enough limit guide 22, guarantee, when spring main part 1 is stretching, limit guide 22 slides and wears to establish and guide spring main part 1 to stretch the action along the parallel and level direction of limit guide 22 guide constantly in guide chamber 21.
