Detailed Description

To further illustrate the technical means and effects of the present invention for achieving the intended purpose of the utility model, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Example 1:

the embodiment provides a pair of front and back shell limit structure, including preceding shell 1 and backshell 2, be equipped with pin thread 3 on the preceding shell 1, be equipped with on the backshell 2 with pin thread 3 matched with box 4, backshell 2 upper end both sides still are equipped with buckle 5, be equipped with draw-in groove 6 on the preceding shell 1, draw-in groove 6 include baffle 12 and with 5 complex location muscle 11 of buckle, baffle 12 cross-section is "Contraband" font to enclose into the space that supplies buckle 5 to stretch into with preceding shell 1 inner wall, location muscle 11 is located baffle 12 on the inner wall of preceding shell 1 one side, still be equipped with opening 13 on baffle 12, baffle 12 is equipped with strengthening rib 10 with preceding shell 1 inner wall department of meeting. In order to avoid bending deformation of the baffle 12, the two sides of the baffle 12 are provided with the rib plates 9, and the reinforcing rib 10 is positioned between the two rib plates 9. In order to ensure that the assembling tightness is higher, the clamping hook is not easy to loosen and the product is firmer, the buckle 5 comprises a clamping hook 7 and a rib plate 8, the fit clearance between the clamping hook 7 and the clamping groove 6 is 0-0.4mm, and the fit clearance between the rib plate 8 and the clamping groove 6 is 0-0.3 mm.

Through the design, in the actual use process, as shown in fig. 1-11, the side edge of the front shell 1 is provided with the male buckle 3, the side edge of the rear shell 2 is provided with the female buckle 4 matched with the male buckle 3, the front shell 1 and the rear shell 2 are not easy to deform through the assembly of the female buckle 4 and the male buckle 3, the two sides of the upper end of the rear shell 2 are also provided with buckles 5, the buckles 5 comprise hooks 7 and rib plates 8, the two sides of the upper end of the front shell 1 are provided with clamping grooves 6 matched with the buckles 5, the clamping grooves 6 comprise baffle plates 12 and positioning ribs 11 matched with the buckles 5, the cross sections of the baffle plates 12 are Contraband-shaped, and forms a space for the buckle 5 to extend into with the inner wall of the front shell 1, the positioning rib 11 is positioned on the inner wall of the baffle 12 facing to one side of the front shell 1, still be equipped with opening 13 on baffle 12, through opening 13, the user of being convenient for stretches into the finger and goes to press down buckle 5 for it is more convenient to use, and buckle 5 and draw-in groove 6 assemble inseparabler. The positioning rib 11 and the hook 7 are matched with each other for assembly.
