Abstract
The utility model provides an eccentric wear-resistant sliding type locking centralizer for an oil well sucker rod. The utility model is mainly characterized in that a hinge type fixing iron card is cast into a reinforced nylon wear-resistant body, the reinforced nylon wear-resistant body and the hinge type fixing iron card are combined as a whole, and a cylinder is formed in the middle after the reinforced nylon wear-resistant body and the hinge type fixing iron card are combined. When the utility model is used, a sucker rod is clamped in the middle of the eccentric wear-resistant sliding type locking centralizer for the oil well sucker rod, after the hinge type fixing iron card is closed, the hinge type iron card is fastened by a screw bolt and thus the utility model has the function of the centralizer and prevents the eccentric wear to the sucker rod. The utility model has the advantages that the utility model has the better functions, such as a centralizing function, a wear-resistant function, a pressure-resistant function, an impact-resistant function, etc., and in addition, the utility model also has the advantages of beautiful appearance, convenient dismounting and high practicability.
Description
Technical field:
The utility model relates to the centralizer of the anti-eccentric wear of a kind of well rod, the anti-eccentric wear slidingtype locking of particularly a kind of well rod centralizer.
Technical background:
At present, the centralizer that well rod uses, great majority are the push-to-close centralizer, this kind centralizer needs split type push-tight nylon after being buckled together, is installed and fixed the iron card more in use.Because push-tight nylon will be buckled together, very require great effort during installation and more inconvenient when dismantling, have only destruction just can take off, when taking off, very easily cause beam hanger to damage, and need make whole oil pipe replacing, so just lost the effect of centralizer.
Summary of the invention:
The utility model is the deficiency that exists in the above-mentioned technology, and the anti-eccentric wear slidingtype locking of a kind of well rod centralizer is provided.This centralizer is than the push-to-close centralizer, and is not only easy for installation, and dismounting is very easy to.During use, open the anti-eccentric wear slidingtype locking of well rod centralizer, be buckled on the sucker rod, the anti-eccentric wear slidingtype locking of the well rod that closes then centralizer gets final product with securing member is fastening at last.
The purpose of this utility model is achieved in that and comprises enhancing nylon wear body that hinge type is the iron card fixedly.It is characterized in that: with hinge type fixedly iron card casting to strengthening nylon wear body the inside, strengthen the nylon wear body and fixedly the iron card be combined into one, form a cylinder in the middle of the back of closing.During use, in the middle of the anti-eccentric wear slidingtype locking of well rod centralizer, behind the iron card that closes fixedly, fastening bolt is fastening gets final product for usefulness with rod grip.So just can play the effect of centralizer, prevent the sucker rod wearing and tearing.
The utility model possesses following advantage: have preferably set upright, wear-resisting, resistance to compression, effect such as shock-resistant.Its profile is more attractive in appearance in addition, dismounting is more convenient, more practical.
After the anti-eccentric wear slidingtype locking of well rod centralizer opened, hinge type fixedly iron card can directly be buckled on the sucker rod, and the anti-eccentric wear slidingtype of the well rod that closes is then locked centralizer, uses fastening bolt fastening again.Along with moving up and down of sucker rod, centralizer also moves up and down thereupon.Therefore, the enhancing nylon wear body of the anti-eccentric wear slidingtype locking of well rod centralizer and hinge type fixedly iron card can both play the effect of protecting sucker rod, reduce wear.

Fig. 1 is a front view of the present utility model
Fig. 2 is Fig. 1 vertical view
Fig. 3 is the left view of Fig. 1
Fig. 4 is the A-A sectional drawing of Fig. 2
The specific embodiment:
Below in conjunction with accompanying drawing present embodiment is described further:
1 for strengthening the nylon wear body as shown in Figure 1, and 2 are the fixing iron card of hinge type, and 3 is bolt hole.
As shown in Figure 24 for hinge type fixedly the iron card the page or leaf sheet.
By Fig. 1 and Fig. 2 as can be known, with hinge type fixedly iron card 2 adopt the method for castings to cast onto to strengthen in the nylon wear body 1, strengthen nylon wear body 1 and hinge type fixedly iron card 2 be combined into one cylinder of formation in the middle of the back of closing.During use, with hinge type fixedly the page or leaf sheet 4 of iron card open, the anti-eccentric wear slidingtype locking of well rod centralizer is buckled on the sucker rod, the fixedly page sheet 4 of iron card of hinge type that closes then, fastening by bolt hole 3 usefulness fastening bolts.Can more detailed, clearerly describe internal construction of the present utility model by Fig. 3 and Fig. 4.
