Embodiment

Prior art panel beating guide rail processing technology is complicated in order to solve, problems such as intensity is low, precision is low, versatility difference, and the utility model provides a kind of composite guideway, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, does not limit the utility model.

Shown in Fig. 1～4, the utility model embodiment relates to a kind of composite guideway, comprising:

Basis guide rail 10, basic guide rail 10 is identical with existing guide rail shape, and length can be according to the difference of module and difference, is provided with the slot of module insertion above the basic guide rail 10.Basis guide rail 10 can adopt the aluminium section bar structure, and like this, according to different insert modules, when producing the basic guide rail 10 of different length, as long as intercepting is just passable, technology is simple, and is easy to operate.In addition, basic guide rail 10 adopts the aluminium section bar structure, and section bar can be drawn into random length, on precision and intensity, can access good assurance,

Guide rail 10 two ends, basis are provided with 101, one basic guide rails of buckle insertion groove, 10 two ends two buckles 20 are installed.Buckle 20 is provided with plug 201, and plug 201 inserts in the buckle insertion groove 101 through interference fit, and like this, buckle 20 has just linked into an integrated entity with basic guide rail 10.Buckle 20 is provided with the card post 202 of outside protrusion; Be provided with some on the fixed structure 30 to buckle installing hole 301; The card post 202 that is installed in the buckle 20 at basic guide rail 10 two ends snaps in respectively on the fixed structure 30 in any a pair of buckle installing hole 301, like this, has just formed composite guideway.Also be provided with trip 203 on the buckle 20, trip 203 is stuck on the base of fixed structure 30, promptly is stuck in the external margin place of fixed structure 30.When buckle 20 adopted working of plasticss, trip 203 had elasticity, and when card post 202 snapped in the buckle installing hole 301 on the fixed structure 30, trip 203 contacted with the base of fixed structure 30, under the effect of pressure, near basic guide rail 10 1 side generation elastic deformations; When card post 202 gets into buckle installing hole 301 fully; The base of fixed structure 30 is not contacting with trip 203; Be hooked under the effect of elastic force and reset, be stuck in the external margin place of fixed structure 30, so just guarantee basic guide rail 10 is stuck on the fixed structure 30 firmly.
