Greatly, the danger for directly opening the unlatching door of boiler coal filling hole is very big, and unlatching personnel can be damaged when serious.In order to prevent
Had an accident during the unlatching door for directly opening boiler coal filling hole, boiler industry has secondary opening function in the urgent need to one kind
Boiler coal filling hole unlatching door.The unlatching topmost part of door of this boiler coal filling hole with secondary opening function is exactly
Secondary opening door hook, only designs secondary opening door hook, and on secondary opening door, can just make secondary opening door tool
There is the function of secondary opening.
The content of the invention：
The invention aims to provide a kind of secondary opening door that can make secondary opening door that there is secondary opening function
Hook.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of secondary opening door hook, including spherical sleeve and coupler body, the top of coupler body is handle, and bottom is hook,
The position that handle is connected with hook is provided with an axis hole.One spherical sleeve is installed on the top of handle, secondary opening is switched
It is both laborsaving during door, it is right heat-insulated, it is easy to operation.The hook has two gib heads, that is, go up gib head and lower gib head, the position of upper gib head
Higher than lower gib head, one section of open hole is provided between upper gib head and lower gib head.
In the present invention, the upper gib head is designed as " u " shape, and lug boss is provided with leading inside, prevents fixing axle from upper
Skidded off in gib head, Baltimore groove is provided with upper gib head bottom, the elasticity of upper gib head can be strengthened, clamping is provided with the both sides of Baltimore groove
Portion, can make gib head form two linear contact lays with the external peripheral surface of fixing axle, increased the contact site of gib head and fixing axle
Position, is used to the axle that is fixedly clamped.
In the present invention, the inner and outer surfaces of the lower gib head are set to circular arc, and end is provided with smooth extension, both
It is easy to hook fixing axle, fixing axle is deviate from from lower gib head when being easy to open the door again.
In the present invention, the length of the open hole faces admittedly open hole when opening the door more than the diameter of fixing axle
Dead axle, is easy to coupler body to be separated with fixing axle.
The beneficial effects of the invention are as follows construction is simple, easy to manufacture, easy to use, safe, long service life, just
In I＆M, can make secondary opening door that there is secondary opening function.
Brief description of the drawings：
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the invention.
Fig. 2 is closed mode figure of the invention.
Fig. 3 is first time opening figure of the invention.
In figure：1 spherical sleeve, 2 handles, 3 hooks, gib head, 311 clamping sections, 312 lug bosses, 313 Baltimore grooves, 32 on 31
Lower gib head, 321 extensions, 4 axis holes, 5 open holes, 6 fixing axles.
Specific embodiment：
As shown in figure 1, a kind of secondary opening door hook, including spherical sleeve 1 and coupler body, the top of coupler body is handle 2, under
Portion is hook 3, and the position being connected with hook 3 in handle 2 is provided with an axis hole 4.A knob is installed on the top of handle 2
Set 1, it is both laborsaving during switch secondary opening door, it is right heat-insulated, it is easy to operation.The hook 3 has two gib heads, that is, go up the He of gib head 31
Lower gib head 32, the position of upper gib head 31 is higher than lower gib head 32, and one section of open hole 5 is provided between upper gib head 31 and lower gib head 32.
The upper gib head 31 is designed as " u " shape, and lug boss 312 is provided with leading inside, prevents fixing axle 6 from being skidded off from upper gib head 31,
Baltimore groove 313 is provided with the bottom of upper gib head 31, the elasticity of upper gib head 31 can be strengthened, clamping section is provided with the both sides of Baltimore groove 313
311, gib head 31 can be made to form two linear contact lays with the external peripheral surface of fixing axle 6, gib head 31 is increased with fixing axle 6
Contact site, is used to the axle 6 that is fixedly clamped.The inner and outer surfaces of the lower gib head 32 are set to circular arc, and end is provided with smooth prolonging
Exhibition portion 321, is both easy to hook fixing axle 6, and fixing axle 6 is deviate from from lower gib head 32 when being easy to open the door again.The length of the open hole 5
Open hole 5 is faced fixing axle 6 by degree more than the diameter of fixing axle 6 when opening the door, and is easy to coupler body to be separated with fixing axle 6.
As shown in Fig. 2 the upper gib head 31 of secondary opening door hook 3 hooks fixing axle 6, now secondary opening door is locked.
As shown in figure 3, the lower gib head 32 of secondary opening door hook 3 hooks fixing axle 6, now the unlatching one of secondary opening door is small
Segment distance.
Operation principle and operating method：When secondary opening door by it is locked when, it is fixed as shown in Fig. 2 driving handle 2 to the right
Axle 6 is deviate from from upper gib head 31, and with the motion upwards of secondary opening door, lower gib head 32 hooks solid coupler body during motion upwards
Dead axle 6, secondary opening door stops motion upwards, and now secondary opening door opens a small distance.Then driving handle 2 to the left,
When the open hole 5 for linking up with 3 faces fixing axle 6, secondary opening door is started upwards, hook 3 is separated with fixing axle 6, secondary to open
Door is opened to be opened.
When secondary opening door need by it is locked when, first by secondary opening door tightly press, gib head 31 is faced fixation
Axle 6, driving handle 2 to the left of at this moment exerting oneself, upper gib head 31 opens suitable for reading under elastic reaction, hooks fixing axle 6.Now, rise to the bait
Fixing axle 6 is clamped in first 31 two clamping sections 311, and the lug boss 312 of the front end of upper gib head 31 stops fixing axle 6, can prevent solid
Dead axle 6 is skidded off from upper gib head 31.
