Description
Technical field
This utility model relates to fixture fittings field, is specifically related to a kind of telescopic bolt connected for furniture.
Background technology
It is one of most commonly seen connected mode that nut coordinates with bolt, and it is in addition to being fastenedly connected component of machine, is also widely used in field of furniture, such as connection between plank on sofa.After plain nut is screwed into bolt, for preventing from skidding, people typically require two spanners of use and it are tightened operation, and i.e. one spanner is stuck in bolt head, and another spanner blocks nut and rotates it, makes bolts and nuts generation relative motion.For increasing the contact area between bolt head and spanner, the comparison that bolt head is generally all manufactured is thick, and nut and bolt can convex be exposed on the outer surface of furniture, when people use furniture by bolt head after being fastenedly connected, thicker bolt head is easy to encounter the arm of people or lower limb, makes troubles to use.But bolt head relatively thin time, during spanner tights a bolt, easily occur spanner extruding plank situation, cause plank to be subject to certain damage.
Now needing to design a kind of moveable bolt of bolt head, during overcoming bolt to tighten, spanner easily extrudes a difficult problem for object.
Utility model content
The purpose of this utility model is to provide a kind of moveable bolt of bolt head, and during overcoming bolt to tighten, spanner easily extrudes a difficult problem for object.
For reaching above-mentioned purpose, base case of the present utility model is: the telescopic bolt connected for furniture, including bolt head and threaded rod, the end of described threaded rod is provided with supporting rod, and the shape of cross section of this supporting rod is polygon, and supporting rod is additionally provided with limited block；Described bolt head is provided with the chute matched with supporting rod, and the sidewall of this chute is provided with the stopper slot matched with limited block.
Operation principle and the advantage of this programme are: during specifically used telescopic bolt, the plank first connected through needs by threaded rod, then by nut sleeve on threaded rod, then make bolt head move to the end of supporting rod.Now the end face of bolt head and plank have certain gap, thus add spanner and twist the space of bolt head, overcome spanner when twisting bolt head, there is object and interfere, cause the difficult problem that object is extruded.When, after nut screwing clamping, tapping bolt head, make bolt head move to original position on supporting rod.
The moveable feature of this programme ingehious design bolt head, solves bolt spanner impact on object in rundown process.It addition, this programme uses shape of cross section to be that polygonal supporting rod is easy for the bolt head moment of torsion transmission to supporting rod.The mobile space to bolt head of limited block carries out spacing, it is to avoid bolt head comes off from supporting rod.
Preferred version one: based on the preferred version of scheme, described stopper slot is dovetail groove, and the shape of cross section of described supporting rod is square.This programme uses dovetail groove, during bolt head moves, the most steadily；Additionally dovetail groove also guide effect.The shape of cross section of supporting rod selects square to be to facilitate processing and manufacturing.
Preferred version two: the preferably preferred version of: described supporting rod is one-body molded with threaded rod, and the junction arc transition of supporting rod and threaded rod.This programme uses one-body molded, is on the one hand convenient processing, is on the other hand the intensity improving supporting rod with threaded rod junction.Supporting rod and threaded rod contact position arc transition are to avoid stress to concentrate.
Preferred version three: the preferably preferred version of two: described threaded rod is provided with escape, the width of this escape is 3 ~ 5mm, and the screw thread of threaded rod is T-shaped screw thread.Design escape on threaded rod, be the processing facilitating screw thread, situation about forging a knife during reducing screw thread process.Selecting T-shaped screw thread is to reduce the situation generation that nut occurs that during tightening silk tooth ruptures.
Accompanying drawing explanation
Fig. 1 is the structural representation of the telescopic screw embodiment that this utility model connects for furniture；
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: bolt head 10, threaded rod 20, escape 21, supporting rod 22, limited block 23.
Embodiment is the most as shown in Figures 1 and 2: the telescopic bolt connected for furniture, mainly includes bolt head 10 and threaded rod 20.Threaded rod 20 is provided with escape 21, and the width of this escape 21 is 3mm, and the screw thread of threaded rod 20 is T-shaped screw thread.The left part of threaded rod 20 is provided with supporting rod 22 integrated with it, and the junction arc transition of supporting rod 22 and threaded rod 20.The shape of cross section of this supporting rod 22 is polygon, can be triangle, tetragon, pentagon, hexagon, and regular polygon is selected in this enforcement.Being additionally provided with limited block 23 on supporting rod 22, bolt head 10 is provided with the chute matched with supporting rod 22, and the sidewall of this chute is provided with the stopper slot matched with limited block 23, and stopper slot is dovetail groove.
During specifically used telescopic bolt, the plank first threaded rod 20 connected through needs, then by nut sleeve on threaded rod 20, then make bolt head 10 move to the left part of supporting rod 22.Now the end face of bolt head 10 and plank have certain gap, thus add spanner and twist the space of bolt head 10, overcome spanner when twisting bolt head 10, there is the interference of object, cause the difficult problem that object is extruded.When, after nut screwing clamping, tapping bolt head 10, make bolt head 10 move to original position on supporting rod 22.
The moveable feature of this programme ingehious design bolt head 10, solves bolt spanner impact on object in rundown process.It addition, the supporting rod 22 that this programme uses shape of cross section to be square is easy for bolt head 10, the moment of torsion of supporting rod 22 is transmitted.The mobile space to bolt head 10 of limited block 23 carries out spacing, it is to avoid bolt head 10 comes off from supporting rod 22.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
