Abstract
A small size ceramic bolt is mainly and integrally formed by a ceramic screw body and a ceramic screw head through a die, wherein the ceramic screw head is a cylinder, a hexagonal counter bore is formed in the upper end face of the ceramic screw head, and a hexagonal end is arranged on the upper portion of the ceramic screw head of the cylinder. The small size ceramic bolt is integrally formed by adopting ceramic, especially zirconia materials, through die pressing, the prior art is improved, and the small size ceramic bolt has the advantages of being reasonable in structure, convenient to machine, capable of resisting high temperature, firm, durable and the like.
Description
Technical field
The utility model relates to a kind of small-sized bolt by ceramic making, belong to technical field of fastening.
Background technique
Bolt, as a kind of link of fastening use, belongs to a kind of standard piece product of routine, and application is comparatively extensive, and it is mainly made up of metal or plastics, comprises the hexagon screw head of screw rod body and disjunctor.But existing bolt connects for conventional parts substantially, picture is in special occasion, as used in the condition of high temperature or small sized product, conventional bolt is just difficult to be suitable for, because under the condition of high temperature, the use of conventional bolt will not have fastening effect because conventional bolt is difficult to high temperature resistance, therefore as very under high-temperature (as 1000 DEG C of left and right) conventional metal bolts can be subject to thermal softening, screw thread distortion impaired etc.For the connecting bolt of small parts, because screw thread is tiny, metal processing reject rate is high, therefore cannot utilize conventional bolt processing technique to carry out the making of stove bolt.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of with ceramic making, rational in infrastructure, easy to process, can high temperature resistant and robust small-sized ceramic bolt.
The purpose of this utility model completes by following technical solution, it is mainly made of one piece by mould by ceramic screw rod body and ceramic screw head, it is characterized in that described ceramic screw head is cylindrical body, on its upper-end surface, offer hexagon counterbore, and be shaped with hex end on cylindrical ceramic screw head top.
The utlity model has rational in infrastructure, easy to process, applied widely, easy to use and reliable, can be high temperature resistant and sturdy and durable etc. feature.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of screw head described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1,2, small-sized ceramic bolt described in the utility model, it is mainly made of one piece by mould by ceramic screw rod body 1 and ceramic screw head 2, described ceramic screw head 1 is cylindrical body, on its upper-end surface, offer hexagon counterbore 3, and be shaped with hex end 4 on cylindrical ceramic screw head 1 top.The utility model adopts pottery, especially zirconia material is made of one piece by mold pressing, it is the one improvement to prior art, owing to being small-sized bolt, inner hexagonal hole and outer-hexagonal shape termination are set on screw head, be conducive to the popularity of use occasion, make Applicable scope large, use more convenient.
Pottery described in the utility model is zirconium oxide, it is also calcined and forms after adopting specialized mould compressing, it is a kind of refractory material, have and there is comparatively hard characteristic, owing to being that mould-forming forms, calcine afterwards surface Machining a little, become a kind of finished product, therefore processing technology is simple, and cost is low, can substitute existing fabricated metals or plastic article completely.
