The utility model content
The purpose of this utility model is to provide a kind of guide pipe bindiny mechanism, to overcome the currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of guide pipe bindiny mechanism, comprise guide pipe, spherical cover and casing cover, one end of described guide pipe is provided with spheroid, the outer cover of described spheroid has the spherical cover matched, be provided with some flutings along even circumferential on the outer wall of described spherical cover, described casing cover one end is provided with groove, and described groove matches with the profile of spherical cover, and described spherical putting is provided with the axially stop block matched with guide pipe and casing cover respectively.
Further, the material of described guide pipe and spherical cover is plastics, and the material of described casing cover is metal.
Preferably, described fluting is U-shaped groove.
Further, the endoporus of described spherical cover is the bowl-shape endoporus with the spheroid free-running fit.
Further, described spherical cover endoporus is provided with to projecting inward fin near the upper opening place, and the internal diameter of described fin is less than the diameter of spheroid.
Further, described spherical cover top open part is provided with outwardly seamed edge, and the inwall of described casing cover one end is provided with the draw-in groove matched with seamed edge.
The beneficial effects of the utility model are: by simplifying and improve the structure of mechanism self, save part, and change the metal guide pipe into plastic material, reduced cost; Improved the structure of connecting bridge between guide pipe and casing cover, not only make the performance of whole assembly be improved, and assembly technology also simplified, only with assembling easily manually, save the operation of closing in casing cover, avoid the coating of metal sleeve lid damaged because of closing in; Greatly reduced overhours, improved production efficiency, manufacturing cost is corresponding reduction also.
The accompanying drawing explanation
Below with reference to the accompanying drawings the utility model is described in further detail.
Fig. 1 is the decomposing schematic representation of the described guide pipe of the utility model embodiment bindiny mechanism;
Fig. 2 is the structural representation of the described guide pipe of the utility model embodiment bindiny mechanism;
Fig. 3 is the cutaway view of the described guide pipe of the utility model embodiment bindiny mechanism.
In figure:
1, guide pipe; 1.1, spheroid; 2, spherical cover; 2.1, fin; 2.2, seamed edge; 2.3, U-shaped groove; 3, casing cover; 3.1, groove; 3.2, draw-in groove.
The specific embodiment
As Figure 1-3, the described a kind of guide pipe of the utility model embodiment bindiny mechanism, comprise guide pipe 1, spherical cover 2 and casing cover 3.Described guide pipe 1 is cylindrical tube and for plastic material, its interior bone for heart yearn penetrate by, wherein an end is provided with the spheroid 1.1 that a diameter is greater than the circular hollow section external diameter, after this spheroid assembling, with spherical cover 2, is connected.
Described spherical cover 2 is plastic material, and it is cylindric that outside is, and it is bowl-shape that inner recess is, and the guide pipe spherical part matches with this bowl-shape endoporus, and spheroid 1.1 can be rotated to all directions along opening part spherical cover 2 is interior; Spherical cover 2 top open part lower edges are provided with to projecting inward fin 2.1, and the fin internal diameter is less than the diameter of the bowl-shape endoporus in below, for restricted guidance pipe spheroid 1.1, pack into after spherical cover 2 endoporus can not deviate from; Spherical cover 2 top open part edges are provided with outwardly seamed edge 2.2, for being mounted with casing cover 3; Spherical cover 2 outer walls are provided with four U-shaped grooves 2.3, and this U-shaped groove is four by the outer wall even partition, make it have elasticity and can expand outwardly when guide pipe spheroid 1.1 is packed into, and can inwardly shrink when himself packing the groove 3.1 of casing cover 3 into, are beneficial to assembling; Spherical cover 2 bottoms are provided with a hole, for heart yearn penetrate by.
