Abstract
The utility model discloses a dental lamina, hold the piece including dental lamina body and card, be provided with on the back of dental lamina body and end the position groove, the medial surface of dental lamina body is convex structure, its characterized in that: the card is held the piece and is set up the inboard the first half at the dental lamina body, the card is held and is provided with the draw -in groove that is 90 contained angles on the piece, the bilateral symmetry of draw -in groove is provided with the guide inclined plane. The utility model has the advantages that: simple structure, processing is convenient, dental lamina body structure is novel, and it can use with current high -power power tong is supporting, and the clamping -force of centre gripping sucker rod is big, be difficult to skid.
Description
Technical field
The utility model relates to a kind of dental lamina, specifically, relating to a kind of dental lamina for clamping sucker rod, belonging to oil well head mechanical field.
Background technology
The clamping of existing sucker rod adopts 1.8Y type well repairing power pliers mostly, but along with the increase of drilling machinery power, the chucking power of the Power Tong of 1.8Y type can not meet the clamping of sucker rod.But the dental lamina of existing high-power Power Tong is all for grip sleeve, oil pipe and drilling rod, is not suitable for clamping sucker rod.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 dental lamina, and its structure is simple, easy to process, dental lamina body construction is novel, and it can support the use with existing high-power Power Tong, and the chucking power of clamping sucker rod is large, be not easy to skid.
The technical solution adopted in the utility model is:
A kind of dental lamina, comprise dental lamina body and blocked block, the back side of described dental lamina body is provided with position-arresting groove, the medial surface of described dental lamina body is arc-shaped structure, described blocked block is arranged on inner side the first half of dental lamina body, described blocked block is provided with the draw-in groove in 90 ° of angles, the bilateral symmetry of described draw-in groove is provided with guide ramp.
Further, described blocked block and dental lamina body are an overall structure.
The utility model has the advantages that: structure is simple, easy to process, dental lamina body construction is novel, and it can support the use with existing high-power Power Tong, the chucking power of clamping sucker rod is large, be not easy to skid.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Wherein: 1, dental lamina body, 2, blocked block, 3, position-arresting groove, 4, draw-in groove, 5, guide ramp.
Detailed description of the invention
As shown in Figure 1, a kind of dental lamina, comprise dental lamina body 1 and blocked block 2, blocked block 2 and dental lamina body 1 are an overall structure, the back side of dental lamina body 1 is provided with position-arresting groove 3, and the medial surface of dental lamina body 1 is designed to arc-shaped structure, and blocked block 2 is arranged on inner side the first half of dental lamina body 1, blocked block 2 is provided with the draw-in groove 4 in 90 ° of angles, the bilateral symmetry of draw-in groove 4 is provided with guide ramp 5.
