Reduce at the fit clearance of knob and plug valve, when needing to dismantle knob, user must exert oneself drawing or to be agitated with screwdriver
Knob, due to knob shape can not fine stress, often resulting in knob and slipping out of the hand or inadvertently fall off leads to the case where breaking damage
Occur.
Summary of the invention
The object of the present invention is to provide knob tool is pulled out, solved by the cavity formed between first shell and second shell
Knob is slipped out of the hand or is inadvertently fallen off and causes the problem of breaking damage, and extracts more labor-saving when knob.
The technical scheme adopted by the invention is that:
Pull out knob tool comprising first shell, second shell and connection component, the first shell and second shell
It is oppositely arranged and is formed cavity, the first shell and second shell are connect with connection component；First is opened along connection component
Knob to be pulled out is placed in cavity by shell and second shell, is then closed first shell and second shell and is pulled up,
Extract knob.
The features of the present invention also characterized in that
The bottom surface of the first shell and second shell is respectively arranged with the first half bore and the second half bore, first half bore
The circular hole to be formed for fixed knob valve rod to be pulled out is matched with the second half bore.
The top surface of the first shell and second shell, which extends outward to form semicircular first, pulls out ear and second and pulls out ear,
After the first shell and second shell closure, first, which pulls out ear and second, pulls out ear and is closed to be formed and circular pull out ear.
The connection component includes fulcrum, the first cylinder and the second cylinder, and described the first cylinder is set on fulcrum simultaneously
It is connect with first shell, described the second cylinder is set on fulcrum and connect with second shell.
The fulcrum is threaded.
Further comprise thread plug, thread plug setting threaded lower end be used for the first cylinder and the second cylinder into
Row limit.
The diameter of the thread plug is greater than the diameter of the first cylinder and the second cylinder.
The first shell pulls out ear integrated molding with first.
The second shell pulls out ear integrated molding with second.
Compared with prior art, the present invention will revolve in use, along connection component opening first shell and second shell wait pull out
Button is placed in cavity, is then closed first shell and second shell and is pulled up, extract knob, the knob of extraction can stay
In cavity, knob is avoided to lead to the case where breaking damage appearance due to inadvertently falling off.
Detailed description of the invention
Fig. 1 is that the embodiment of the present invention provides the structural schematic diagram pulled out when knob tool is in opening；
Fig. 2 is that the embodiment of the present invention provides the structural schematic diagram pulled out when knob tool is in closure；
Fig. 3 is that the embodiment of the present invention provides the cross-sectional view for pulling out knob tool；
Fig. 4 is that the embodiment of the present invention provides the usage state diagram for pulling out knob tool.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention offer pull out knob tool, as shown in Figure 1-3, it include first shell 1, second shell 2 and
Connection component 3, first shell 1 and second shell 2 are oppositely arranged and are formed cavity 4, and first shell 1 and second shell 2 are and even
Connected components 3 connect；In this way, opening first shell 1 and second shell 2 along connection component 3, knob to be pulled out is placed in cavity 4, so
It is closed first shell 1 and second shell 2 afterwards and is pulled up, knob is extracted.
The bottom surface of first shell 1 and second shell 2 is respectively arranged with the first half bore 11 and the second half bore 21, the first half bore 11
It is formed with the matching of the second half bore 12 and is kept away for the circular hole 5 of fixed knob valve rod to be pulled out in this way, knob valve rod is placed in circular hole 5
The damage to knob valve rod is exempted from.
The top surface of first shell 1 and second shell 2, which extends outward to form semicircular first, pulls out ear 12 and second and pulls out ear
22, after first shell 1 and second shell 2 are closed, first pull out ear 12 and second pull out the closure of ear 22 formed it is circular pull out ear 6, first
Shell 1 and first pulls out the integrated molding of ear 12, and second shell 2 and second pull out the integrated molding of ear 22, in this way, being made by pulling out ear 6 conveniently
User operates stress, and extraction dynamics is smaller than singly pulling out knob.
Connection component 3 includes fulcrum 31, the first cylinder 32 and the second cylinder 33, and the first cylinder 32 is set on fulcrum 31
And connect with first shell 1, the second cylinder 33 is set on fulcrum 31 and connect with second shell 2, and fulcrum 31 is threaded, this
Sample, the first cylinder 32 and the second cylinder 33 drive first shell 1 and second shell 2 to move in the opposite direction, make first shell 1
It opens or is closed with second shell 2.
It further comprise thread plug 34, the setting of thread plug 34 is used in threaded lower end to the first cylinder 32 and the second cylinder
33 are limited, and the diameter of thread plug 34 is greater than the diameter of the first cylinder 32 and the second cylinder 33, are being used in this way, avoiding
The first cylinder 32 and the second cylinder 33 slide from fulcrum 31 in journey.
Application method: as shown in figure 4, the first cylinder 32 and the second cylinder 33 drive first shell 1 and second respectively first
Shell 2 moves in the opposite direction, opens first shell 1 and second shell 2, and knob to be pulled out is placed in first shell 1 and the
In the cavity 4 that two shells 2 are formed, valve rod is placed in circular hole 5, is continued through the first cylinder 32 and the second cylinder 33 later and is driven the
One shell 1 and second shell 2 are closed, and are held and are pulled out the lifting upwards of ear 6, until knob is extracted, the knob after extraction can stay in sky
In chamber 4.
Using the above scheme, compared with prior art, the present invention is in use, open first shell and second along connection component
Knob to be pulled out is placed in cavity by shell, is then closed first shell and second shell and is pulled up, extracts knob,
The knob of extraction can stay in cavity, and knob is avoided to lead to the case where breaking damage appearance due to inadvertently falling off.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
