Abstract
The horse head pin of pumping unit that a kind of shank can swell and dwindle: constitute for main body by pin cap (5), pin core (2), common pin (9), pin core external screw (3) and pin cap interior screw socket (4) cooperation of pin core (2) by the middle part is connected and is connected, after a shank taper hole (8) is made a call at the center of normal pins (14), impartial again is cut into three lobes with axial direction, and each lobe is inlaid in the pin cap along groove (10) lining by top eaves (11); Shank Returnning spring groove (12) lining is with shank Returnning spring (13) and has formed a complete pin configuration.In the time will extracting pin: grasp handle (1) rotating dog core (2) pin core (2) is risen; The normal pins (9) that is cut into three lobes is gathered to the center under the effect of shank Returnning spring (13), and the shank external diameter that normal pins (9) surrounds just can easily be extracted less than the internal diameter of pin-and-hole (6).
Description
Affiliated technical field
The present invention relates to a kind of horse head pin of pumping unit.
Background technique
At present, the horse head pin that pumping unit uses is direct insertion pin: its basic profile all is T-shape, and " " on T-shape top is referred to as the pin top, bottom " Shu " is referred to as shank.Pin-and-hole directly be squeezed into or be got to this pin need with sledgehammer.Its defective is: insert or when extracting pin at every turn, the operator all to " shoulder " sledgehammer climb pumping unit overhead the horse head of 7-8 rice height survey on the face vertical wall, climb on the other hand and hold up a handwheel sledgehammer.Such operation be can't put on a spurt, extremely danger, also often runs into the phenomenon that pin corrosion " long dead " originally can't be got pin-and-hole Rigen.
Summary of the invention
In order to overcome the deficiency of existing horse head pin, the invention provides a kind of expansion and shrinkage type horse head pin of pumping unit, this pin can not only easily insert and extract, and processing technology is simple, cheap, intensity is high.
The technical solution adopted for the present invention to solve the technical problems is: at first make a pin cap that independently is the bottle cap shape, there is the hole of band spiral shell button at its center, interior along on dug a groove; A pin core is installed in the hole, and an end of pin core is pin core top, and the hole of a dress bracelet is arranged on the pin core top, and the middle part is the leading screw that matches with pin cap center spiral shell button, and the other end of pin core is a cone; The center of circle of normal pins be equipped with one with the pin core on the taper hole that matches of cone tapering, on the periphery of shank, dug twice Returnning spring groove, with after axially being split into three impartial lobes, each the lobe pin top that on average is split into three lobes is inlaid into the interior along in the groove of pin cap again; Each lobe shank spring that is reset draws in by the Returnning spring groove and to form " one ".
The invention has the beneficial effects as follows: can insert easily and when extracting pin; Can also fix pumping unit horsehead; Simple in structure, intensity is high.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the fixedly state generalized section of shank during horse head of horse head pin of the present invention.
1. bracelets among the figure, 2. pin core, 3. pin core external screw, 4. screw socket, 5. pin cap in the pin cap, 6. pin-and-hole, 7. pin core cone, 8. shank taper hole, 9. normal pins, 10. in the pin cap along groove, 11. shank Returnning spring groove, 12. shank Returnning springs, 13. otch slits, 14. waterproof covers, 15. apical pores
Embodiment
In the drawings, pin core (2): penetrate bracelet (1) in the apical pore (15) by what reinforcing bar surrounded one side the top is equipped with one; The middle part is waterproof cover (14) and the pin core external screw (3) that is the bottle cap type; The bottom is to be conical pin core cone (7).Pin cap (5): shape is the bottle cap shape, and a hole that has interior screw socket (4) has been beaten in the center of circle; In the pin cap along in dug in along groove (10), cooperation is connected and is connected the pin core external screw (3) of pin core (2) by the middle part with the interior screw socket of pin cap (5) (4).In normal pins (14): the center make a call to a shank taper hole (8), tapering is consistent with pin core cone (7); Shank periphery branch has dug twice Returnning spring groove (11) up and down; Impartial again is cut into three lobes with axial direction, produces otch slit (13), and each lobe is inlaid in the pin cap along groove (10) lining by top eaves (11).Shank Returnning spring groove (11) lining is with shank Returnning spring (12) and has formed a complete pin configuration.
In the time will inserting pin in the pin-and-hole (6): grasp handle (1) rotating dog core (2) and allow pin core (2) rise; The normal pins (9) that is cut into three lobes is gathered to the center under the effect of shank Returnning spring (13); Three otch (13) narrow down, and at this moment the shank external diameter that surrounds of the normal pins of three lobes (9) just can easily insert less than the internal diameter of pin-and-hole (6); After pin is inserted into the end, grasp handle (1) rotating dog core (2), make pin core (2) decline just can surround shank to the normal pins that is cut into three lobes (9) and outwards strut, open otch slit (13); Form external diameter and the consistent fixing pin of pin-and-hole internal diameter, fixed horse head.
In the time will extracting pin: grasp handle (1) rotating dog core (2) pin core (2) is risen; The normal pins (9) that is cut into three lobes is gathered to the center under the effect of shank Returnning spring (13), and three otch (13) narrow down; At this moment the shank external diameter that surrounds of the normal pins of three lobes (9) just can easily be extracted less than the internal diameter of pin-and-hole (6).
Claims (3)
1. expansion and shrinkage type horse head pin of pumping unit, it is characterized in that based on normal pins: be the main body formation by pin cap (5), pin core (2), common pin (9); Pin core external screw (3) and pin cap interior screw socket (4) cooperation of pin core (2) by the middle part is connected and is connected, after a shank taper hole (8) is made a call at the center of normal pins (14), impartial again is cut into three lobes with axial direction, and each lobe is inlaid in the pin cap along groove (10) lining by top eaves (11); Shank Returnning spring groove (12) lining is with shank Returnning spring (13) and has formed a complete pin configuration.
2. expansion and shrinkage type horse head pin of pumping unit according to claim 1 is characterized in that: bracelet (1) is equipped with at the top of pin core (2).
3. expansion and shrinkage type horse head pin of pumping unit according to claim 1 is characterized in that: there is a waterproof cover (14) at the middle part of pin core (2).
