Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can be mutually combined.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
It it is noted that described further below is all exemplary, it is intended to provide further instruction to the application.Unless otherwise finger
Bright, all technology used herein and scientific terminology have and are generally understood that with the application person of an ordinary skill in the technical field
Identical meanings.
In this utility model, in the case of illustrating on the contrary, the noun of locality of use such as " upper and lower " is typically for attached
For direction shown in figure, or for on vertical, vertical or gravity direction；Similarly, for ease of understand and
Describing, it is inside and outside that " inside and outside " refers to relative to the profile of each parts itself, but the above-mentioned noun of locality is not limited to this reality
With novel.
During in order to solve optical-rod clamp of the prior art with sucker rod assembling, optical-rod clamp is easily by the anti-problem filled, this practicality
Novel providing a kind of optical-rod clamp, optical-rod clamp is following optical-rod clamp.
As shown in Figure 1 to Figure 3, optical-rod clamp include the second card body 20 that the first card body 10 and the first card body 10 be pivotally connected,
Connecting bolt assembly 40 and the stopper section being movably arranged on the second card body 20, the second card body 20 is provided with and dodges breach 30,
First end and first card body 10 of connecting bolt assembly 40 are pivotally connected, and the second end of connecting bolt assembly 40 optionally snaps in
Dodge at breach 30 or exited by dodging breach 30, at the upper surface of the second card body 20 and the lower surface of the second card body 20
When anti-dress state, stopper section is towards dodging at breach 30 motion to occupy at least some of space dodged at breach 30.
As depicted in figs. 1 and 2, specifically, stopper section has the first operating position and the second operating position, such as institute in Fig. 1
Illustrating, when the first card body 10 and the second card body 20 are in correct rigging position, stopper section is positioned at the first operating position,
Stopper section now is in dodges position, and the first card body 10 and the second card body 20 are in the clamped condition of clamping sucker rod 60；As
Shown in Fig. 2, when the first card body 10 and the second card body 20 are in anti-dress state, stopper section is positioned at the second operating position
Time, stopper section now is in stop dog position, and stopper section occupies at least some of space dodged at breach 30.
By arranging the stopper section of activity on the second card body 20, when upper surface and the following table of the second card body 20 of the second card body 20
When face is in anti-dress state, stopper section is towards dodging at breach 30 motion to occupy at least some of space dodged at breach 30.
So, stopper section just serves the effect of backstop connecting bolt assembly 40, makes connecting bolt assembly 40 successfully not snap in and keeps away
Allow at breach 30, thus remind operator's optical-rod clamp to be now in the inverted anti-dress state of upper and lower surface, effectively
Avoid optical-rod clamp and sucker rod 60 when assembling, optical-rod clamp is filled by counter, improves the reliability that optical-rod clamp uses, enters
And improve the safety and stability that oil pumper runs.
As shown in Figure 4 and Figure 5, the second card body 20 has the receiving hole 21 vertically extended, and receiving hole 21 is along the second card
The lower surface of body 20 is through to dodging at breach 30, and stopper section is to be movably arranged on the stop pin 50 at receiving hole 21, backstop
Pin 50 has to dodging extended position that breach 30 stretches out and storage to dodging position in receiving hole 21.Due to the second card
Body 20 has the receiving hole 21 vertically extended, and provides enough receiving spaces for stop pin 50, makes stop pin
50 can move at vertical direction, thus ensure that stop pin 50 can switch between position and stop dog position dodging, it is ensured that
The backstop function of optical-rod clamp successfully realizes.
As it is shown in figure 5, receiving hole 21 is stepped bore, receiving hole 21 includes by dodging breach 30 side to the second card body 20
The first shoulder hole section the 211, second shoulder hole section 212 and the 3rd shoulder hole section 213 of sequentially connecting of lower surface side, wherein,
The cross-sectional area of the first shoulder hole section 211 and the 3rd shoulder hole section 213 is more than the cross-sectional area of the second shoulder hole section 212.So,
Stepped bore can accommodate the stop pin 50 with different-diameter section, it is possible to effectively limits the shift position of stop pin 50,
Ensure that stop pin 50 stably switches between position and stop dog position dodging.
As it is shown on figure 3, stop pin 50 includes being sequentially connected with by dodging the lower surface side to the second card body 20, breach 30 side
The first backstop section 51, changeover portion 52 and the second backstop section 53, wherein, the first backstop section 51 backstop is in the first shoulder hole section 211
The end having a common boundary with the second shoulder hole section 212, the second backstop section 53 backstop is in the second shoulder hole section 212 and the 3rd shoulder hole section
213 ends having a common boundary.So, limit the stop pin 50 maximum displacement in receiving hole 21, and backstop can be made simultaneously
Pin 50 will not drop from receiving hole 21, it is ensured that the reliability of stop pin 50 work.
Alternatively, the first backstop section 51 and/or the second backstop section 53 are detachably connected with changeover portion 52.So, convenient to only
Backing pin nail 50 repairs or replaces, and improves the practicality of stopper section.
In a not shown alternative embodiment, the second card body 20 being additionally provided with engaging lug, stopper section is can pivot with engaging lug
Turn the gear-stopping bar connected, when the upper surface of the second card body 20 and the lower surface of the second card body 20 are in anti-dress state, gear-stopping bar
The opening part dodging breach 30 with block is rotated under gravity around engaging lug.So, conveniently gear-stopping bar is replaced, fall
The low processing and manufacturing difficulty of the second card body 20, moreover it is possible to prevent the greasy dirt condensing in bulk from hindering the motion of stopper section, it is ensured that backstop
Portion is dodging the reliability of switching between position and stop dog position, improves the stability that optical-rod clamp uses.
Alternatively, the first card body 10 is provided with the first slips (not shown), the second card body 20 is provided with and joins with the first slips
The second slips (not shown) closed, the first slips and the second slips are provided with card tooth.So, when the first card body 10 and
When two card bodies 20 are in clamped condition, can stably step up sucker rod 60 by the cooperation of the first slips and the second slips, it is ensured that
The stability that is connected between sucker rod 60 and optical-rod clamp.
Still optionally further, card tooth is obliquely installed towards the upper surface of the second card body 20.
As in figure 2 it is shown, connecting bolt assembly 40 includes connecting bolt 41, attaching nut 42 and pad 43, connecting bolt 41
The first end and the first card body 10 be pivotally connected；Attaching nut 42 is removably disposed in the second end of connecting bolt 41；Pad
43 are arranged between connecting bolt 41 and attaching nut 42.This way it is ensured that connecting bolt assembly 40 can be by the first card body
10 and second card body 20 stably clamp, improve the stability in use of optical-rod clamp.
Alternatively, as shown in Figure 4, the surface being oppositely arranged with the opening dodging breach 30 dodging breach 30 is arc surface.
So, when the first card body 10 and the second card body 20 are in clamped condition, a part for connecting bolt 41 can be pasted with arc surface
Tight setting, improves connecting bolt assembly 40 and the Assembly stability of the second card body 20.
This utility model additionally provides a kind of oil pumper, and oil pumper includes optical-rod clamp, and optical-rod clamp is above-mentioned optical-rod clamp.
