Abstract
The utility model relates to a kind of novel dental lamina, comprise dental lamina body and the regular tooth be distributed on dental lamina body, described dental lamina body is provided with position-arresting groove, it is characterized in that: the width of described dental lamina body reduces from top to bottom gradually, described tooth is transversely arrangedly be distributed on dental lamina body, angle between adjacent two teeth is identical and be 80 ° of angles, and the medial surface of described dental lamina body is arc-shaped structure.The utility model has the advantages that: structure is simple, easy to make, dental lamina body construction novel, be convenient to installation and replacing, tooth is wear-resisting and little to the injury such as oil pipe, drilling pipe, and chucking power is strong.
Description
Technical field
The utility model relates to a kind of dental lamina, specifically, relates to a kind of novel dental lamina, belongs to oil well head mechanical field.
Background technology
Often use the equipment such as hydraulic tongs in petroleum drilling workover treatment, and dental lamina is as the main parts size of hydraulic tongs, it is to playing crucial effect in petroleum drilling workover treatment.Existing dental plate structure tradition, injures comparatively large to oil pipe, drilling pipe etc. and easily skids, and the dental lamina of traditional structure troublesome poeration in installation Renewal process, affects the operating efficiency of drilling and repairing well simultaneously.Therefore, a kind of new technical scheme is needed to solve above-mentioned technical problem.
Utility model content
The purpose of this utility model is to provide a kind of novel dental lamina, and its structure is simple, easy to make, dental lamina body construction novel, be convenient to installation and replacing, and tooth is wear-resisting and little to the injury such as oil pipe, drilling pipe, and chucking power is strong.
The technical solution adopted in the utility model is:
A kind of novel dental lamina, comprise dental lamina body and the regular tooth be distributed on dental lamina body, described dental lamina body is provided with position-arresting groove, the width of described dental lamina body reduces from top to bottom gradually, described tooth is transversely arrangedly be distributed on dental lamina body, angle between adjacent two teeth is identical and be 80 ° of angles, and the medial surface of described dental lamina body is arc-shaped structure.
The utility model has the advantages that: structure is simple, easy to make, dental lamina body construction novel, be convenient to installation and replacing, tooth is wear-resisting and little to the injury such as oil pipe, drilling pipe, and chucking power is strong.
