Abstract
A stud in metric and English system, relating to the machinery fastener designing and manufacturing technical field, comprises a thread section and a screw section; the thread section is arranged at the two ends of the screw section, the metric thread section being arranged at one end and the inch thread section being arranged at the other end. The utility model employs a screw thread process for one stud in two systems, designs a stud in metric and English system which is suitable for connecting different devices, satisfies the existing requirements of well head equipment with both metric connecting bolt holes and inch connecting bolt holes, can choose metric or inch thread for fastening based on requirements in site and be convenient for site operation.
Description
Technical field:
A kind of metric and English stud bolt is used for the connection between two parts or two equipment, belongs to the anchor design manufacturing technology field of mechanical device.
Background technique:
In the prior art, basically all mechanized equipments or device, on connecting, it all to use bolt, the general bolt that is connected with use metric system screw thread, also have and use screw thread bolt made in Great Britain, the existence of these situations mainly equipment manufacturers' accepted standard difference causes, some equipments, particularly main equipment need two all to have the bolt of screw thread when realizing connecting, as the oil and natural gas wellhead assembly, in order to connect the equipment of oil recovery or gas production, when connecting, need use stud bolt, its problem is: connect the bolt hole that wellhead equipment uses at present, has plenty of metric system, have plenty of made in Great Britain, the machinists of site operation in advance and do not know which position of equipment that is connected needs metric system, which position needs English system, therefore, when work,, just only stop work, wait for after suitable connecting bolt is reached the spot just working in case the scene does not have suitable bolt, incur loss through delay the duration, and bring a lot of difficulties for execute-in-place.
Summary of the invention:
The purpose of this utility model is the above-mentioned deficiency at prior art, adopts the screw thread processing method of two kinds of standards of a bolt, has designed the metric and English stud bolt that a kind of suitable distinct device connects.
The utility model is achieved in that the utility model comprises thread section and spiro rod section, is characterized in that: described thread section is arranged on the two ends of spiro rod section, and an end is the metric thread section, and the other end is the inch screw thread section.
During use, the bolt hole of original equipment is made in Great Britain, just inch screw thread one end of this metric and English stud bolt is screwed into the bolt hole made in Great Britain of equipment earlier, load onto the equipment that needs connection then, adopt the nut of metric system to screw in the metric thread of this metric and English stud bolt other end again, tightening nut at last gets final product, if the bolt hole of original equipment is a metric system, just metric thread one end of this metric and English stud bolt is screwed into the metric system bolt hole of equipment earlier, load onto the equipment that needs connection then, adopt nut made in Great Britain to screw in the inch screw thread of this metric and English stud bolt other end again, tighten nut at last and get final product;
Advantage of the present utility model and beneficial effect are: because the utility model has adopted the screw thread of two kinds of different systems of metric and English at two of a bolt, cooperate simultaneously and prepare two kinds of nuts public, made in Great Britain, when implementing on-the-spot connection work, just can select metric system or screw thread made in Great Britain as required for use, the other end then adopts the nut of different systems screw thread to carry out fastening, for site operation brings convenience, can also satisfy on-the-spot usage requirement.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
The utility model is achieved in that the utility model comprises thread section 1,3 and spiro rod section 2, and in the middle of spiro rod section was arranged on, thread section was arranged on the two ends of spiro rod section, and an end is the metric thread section, and the other end is the inch screw thread section;
During use, in order to cooperate the needs of on-the-spot different systems screw thread, be ready to have two kinds of nuts of metric system and inch screw thread earlier, when implementing on-the-spot connection work, just can select metric system or screw thread made in Great Britain as required for use, if the connecting bolt hole of wellsite facility is made in Great Britain, just select for use inch screw thread one end of this metric and English stud bolt to be screwed into the bolt hole made in Great Britain of wellsite facility earlier, carry out fastening to the bolt that is screwed into again, to need the screw of the equipment that connects to pass the stud bolt that is screwed into then positions, and then adopt the metric system nut of preparation in advance to screw in the metric thread of this metric and English stud bolt other end, tighten nut at last and get final product; If the connecting bolt hole of well site original equipment is a metric system, just metric thread one end with this metric and English stud bolt is screwed into earlier in the metric system bolt hole of equipment, to need the screw of connection device to pass the stud bolt that is screwed into then positions, adopt the nut made in Great Britain of preparation to screw in the inch screw thread of this metric and English stud bolt other end again, tightening nut at last gets final product, the screw thread of the two kinds of different systems of metric and English that adopt can bring convenience for site operation, can also satisfy on-the-spot usage requirement.
