Abstract
The utility model discloses a quick joint for oil pipe, which mainly solves the problems that the connection and disassembly of the connecting method of the existing oil pipes are time consuming and labor consuming. The quick joint for an oil pipe is characterized in that upper and lower joints (1, 2) are both provided with threads which are matched with the oil pipe and are connected with a steel ball (3), and a sliding base (4) which is coated by a sliding sleeve (5) is fixed outside the lower joint (2). A spring (6) is provided between stages in the sliding base (4) and the sliding sleeve (5), the internal wall of the upper end of the sliding sleeve (5) is provided with a slot, and the slot is matched with a boss (7) which is provided with a chamfer on the lower joint(2), and the upper and lower joints (1, 2) are sealed. The quick joint for the oil pipe has the advantages of time saving connection and disassembly, labor saving, quick manual disassembly, stretching resistance and high voltage resistance.
Description
Technical field:
Used oil connection when the utility model relates to operation in the oil recovery field, oil field, especially oil pipe snap joint.
Background technology:
At present in the oil recovery field, oil field during operation the connection between the oil pipe be to utilize the internal and external threads on the oil pipe to connect, when interconnecting between the oil pipe or dismantling, need special tool that the oil pipe rotation just can be finished, time-consuming, the effort of operating personnel, simultaneously in operating process, be easy to make thread damage, particularly when being installed, cement cap and anti-circulation well cementation remove oil pipe, the connection of oil pipe and dismounting be difficulty more, and inefficiency influences job scheduling.
The utility model content:
In order to overcome existing oil pipe connected mode connection and to dismantle deficiency time-consuming, effort, the utility model provides a kind of oil pipe snap joint, this oil pipe snap joint tension, high pressure resistant has and connects and dismounting saves time, laborsaving and manual dismounting characteristics efficiently rapidly.
The technical solution of the utility model is: this oil pipe snap joint comprises lower contact, last lower contact all has the screw thread that coincide with oil pipe and is connected by the steel ball cutting ferrule, the lower contact external fixation has the slide that is covered mutually by sliding sleeve, be equipped with spring between slide and the sliding sleeve inner step, sliding sleeve upper end inner wall belt fluted and with lower contact on the boss of band chamfering match, seal between the last lower contact.
Above-mentioned steel ball places in the ball seat in the lower contact; Be equipped with sealing ring between the last lower contact.
The utlity model has following beneficial effect: owing to take such scheme, can be connected last lower contact on the oil pipe, move downward with the hand propelled sliding sleeve, the compression spring, lower contact can make things convenient for and promptly is enclosed within the top connection lower end, slides over after loosing one's grip under the spring force effect to move upward, force steel ball to be stuck in the annular groove of top connection outer wall, make firmly card mutually of lower contact, connect and save time during dismounting, laborsaving, manual dismounting is quick rapidly.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-top connection among the figure, 2-lower contact, 3-steel ball, 4-slide, 5-sliding sleeve, 6-spring, 7-boss, 8-sealing ring.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this oil pipe snap joint comprises lower contact (1,2), last lower contact (1,2) all have the screw thread that coincide with oil pipe and be connected by steel ball 3 cutting ferrules, can be last lower contact (1,2) be connected on the oil pipe, top connection 1 lower end outer wall has the annular sphere groove that coincide with steel ball 3, steel ball 3 places in the ball seat in the lower contact 2, lower contact 2 external fixation have the slide 4 that is covered mutually by sliding sleeve 5, sliding sleeve 5 can slide up and down along the lower contact outer wall, makes radially motion in the ball seat of steel ball 3 in lower contact 2 to be equipped with spring 6 between slide 4 and sliding sleeve 5 inner steps, sliding sleeve 5 upper end inner wall belts fluted and with lower contact 2 on the band chamfering boss 7 match, under spring 6 elastic force effects, sliding sleeve 5 can automatically reset and block mutually with boss 7, plays the effect that connects back locking, being equipped with sealing ring 8 between the last lower contact (1,2) is to leak for fear of producing at Qi Lianchu.
During actual the use, move downward with hand propelled sliding sleeve 5, compression spring 6, lower contact 2 can make things convenient for and promptly is enclosed within top connection 1 lower end, the back sliding sleeve 5 of loosing one's grip moves upward under spring 6 elastic force effects, force steel ball 3 to be stuck in the annular groove of top connection 1 outer wall, lower contact (1,2) is firmly blocked mutually, connect and save time during dismounting, laborsaving, manual dismounting is quick rapidly, has improved operating efficiency, is worth promoting the use of in the oil field.
Claims (3)
1, a kind of oil pipe snap joint, comprise lower contact (1,2), it is characterized in that: go up lower contact (1,2) and all have the screw thread that coincide with oil pipe and be connected by steel ball (3) cutting ferrule, lower contact (2) external fixation has the slide (4) that is covered mutually by sliding sleeve (5), be equipped with spring (6) between slide (4) and sliding sleeve (5) inner step, sliding sleeve (5) upper end inner wall belt is fluted and match with boss (7) that the band chamfering is gone up in lower contact (2), seals between the last lower contact (1,2).
