Wherein, the round-like structure of handstand refers to:The column structure that diameter gradually decreasees from top to bottom.
The operation principle of the pin remover for pressure gauge provided below with regard to the utility model embodiment, which is given, to be described:
Before removing the pointer of pressure gauge, first the front casing of pressure gauge and glass panel are dismantled.The hand steered hammer body of operator 4
The side wall of curved slot arrangement, and the movement central axis portion filing of needle dial is will protrude above using the file face 401 of hammer body 4, so
The open slot 301 of holder 3 is stuck on the movement central shaft below pointer afterwards, rotary screw 1, makes to be set to 1 lower end of lead screw
Thimble 2 withstands the needle dial in the middle part of pointer, and be rotated clockwise makes lead screw 1 move down again, and pointer is risen.
After taking out pointer, the elements such as movement central shaft can be adjusted, later be attached to pointer in movement again
In mandrel, and pointer is struck tightly using hammer body 4.
The pin remover for pressure gauge that the utility model embodiment provides, by setting hammer body 4 to the round-like structure of handstand,
Upper surface is file face 401, and curved slot arrangement of the side wall in opening outwardly can avoid the corner angle scuffing operator's on hammer body 4
Finger, and damage pressure gauge housing, central shaft and dial, the person of being conveniently operated control hammer body 4, convenient for utilizing file face 401
The movement central axis portion filing that will protrude above needle dial, avoids thimble 2 from being supported with the protrusion split-phase and skids, convenient for making thimble
2 directly withstand the needle dial in the middle part of pointer, efficiently to rise by pointer.Also, it can also use hammer body 4 will when installing pointer
It strikes tightly, is easily installed pointer.The pin remover for pressure gauge provided using the utility model embodiment can efficiently be played pointer
Go out, facilitate and firmly install pointer, and the structure of the pin remover for pressure gauge is simple, easy to manufacture.
Lead screw 1 passes through holder 3 threadably, and thimble 2 is made to pass through open slot 301, it can be understood as:Holder
It is provided with internal thread hole on 3, external screw thread, external screw thread and the internal thread hole spiral shell on holder 3 of lead screw 1 are provided on the wall of lead screw 1
Line connects.It is opposite with the open slot 301 of 3 lower end of holder also, after lead screw 1 is thread through internal thread hole.By adjusting lead screw
1 penetrates the length of holder 3, and thimble 2 can be made to pass through open slot 301.
As shown in Fig. 3, the open slot 301 on holder 3 is arranged in the bottom end of holder 3, and along perpendicular to the direction of thimble 2
(horizontal direction) extends to the edge of 3 bottom end of holder, to form opening.
Further, for the ease of operator can easily control hammer body 4 drive lead screw 1 move up and down, also, hand with
It is not easy to skid between hammer body 4, in one possible implementation, protective jacket is set on the side wall of hammer body 4.
For example, multiple arcs compatible with the hand of operator axially spaced can be provided on the outer wall of protective jacket
Connected in star is avoided when control hammer body 4 moves up and down, hand is detached from hammer body 4 in order to which opponent limits.
Alternatively, being provided with the anti-of the regular textures such as round, rectangular, triangle or irregular structure on the outer wall of protective jacket
Sliding line.So set, increasing the frictional force between the hand of operator and hammer body 4, avoid when control hammer body 4 moves up and down,
Hand is detached from hammer body 4.
Wherein, protective jacket can be integrally formed with hammer body 4, can also be by way of welding, bonding or other connections
It is sleeved on hammer body 4.
It can be connected in several ways between hammer body 4 and lead screw 1, based on easy setting, the good premise of connection dynamics
Under, it is given below and illustrates:
In one possible implementation, hammer body 4 is welded to connect with lead screw 1.The dynamics being welded to connect is good, avoids making
Used time, hammer body 4 are disconnected with lead screw 1.
In alternatively possible realization method, hammer body 4 is detachably connected with lead screw 1.It is detachably connected and is conveniently replaceable not
The hammer body 4 and lead screw 1 of same specification.
Wherein, there are many modes that hammer body 4 and lead screw 1 are detachably connected, for example, can be between hammer body 4 and lead screw 1
To be threadedly coupled.The lower end of hammer body 4 is provided with tapped blind hole, and the upper end of lead screw 1 is provided with external screw thread, by making the upper of lead screw 1
End is threadedly coupled with tapped blind hole, realizes the threaded connection of hammer body 4 and lead screw 1.
The length of the lead screw 1 of holder 3, in one possible implementation, hammer body 4 are penetrated for the ease of control screw thread
Lower end is provided with the limited step for offseting with holder 3.
For the ease of replacing the thimble 2 and lead screw 1 of different size, in one possible implementation, the lower end of lead screw 1
It is provided with mounting hole, thimble 2 is detachably connected with mounting hole.
There are many modes that thimble 2 is detachably connected with mounting hole, in one possible implementation, thimble 2
Upper end is connected in mounting hole.
For example, finite place piece is set on the side wall of thimble 2;It is provided on the inner wall of mounting hole for keeping locating part suitable
With the limiting slot being caught in.By making the upper end of thimble 2 be inserted into mounting hole, and locating part adaptation is made to be caught in limiting slot, realized
Thimble 2 is connect with the clamping of lead screw 1.
The structure of limiting slot and locating part is not especially limited, meets and realizes adaptation clamping.
Wherein, thimble 2 is pyramidal structure, and diameter gradually decreasees from top to bottom.The average diameter of thimble 2 can be 0.7
~1.2mm, such as can be 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm etc..
Holder 3 could be provided as various structures, and in one possible implementation, as shown in Fig. 1, holder 3 is in ring
Shape structure.The structure of holder 3 is arranged such, when removing pointer, holder 3 is avoided to damage shell, central shaft, the scale of pressure gauge
Disk etc..
For the ease of open slot 301 to be stuck on movement central shaft, in one possible implementation, such as 3 institute of attached drawing
Show, open slot 301 is to open up the U-shaped opening slot obtained to edge in the horizontal direction by the center bottom of holder 3.U-shaped opening slot
Structure it is simple, be easy setting, convenient for movement central shaft to be caught in it, and its inner cavity is hardly damaged movement central shaft.
Wherein open slot 301 be open width be 2.3~4.3mm, such as can be 2.3mm, 2.7mm, 3.3mm,
3.7mm, 4.3mm etc..
Holder 3 is steadily controlled for the ease of operator, in one possible implementation, is set on the outer wall of holder 3
It is equipped with protective jacket.
It is for example, axially spaced on the outer wall of protective jacket that be provided with multiple arcs compatible with the hand of operator recessed
Slot avoids in order to which opponent limits in hand steered holder 3, and hand is detached from holder 3.
Alternatively, being provided with the anti-of the regular textures such as round, rectangular, triangle or irregular structure on the outer wall of protective jacket
Sliding line.So set, increasing the frictional force between the hand of operator and holder 3, avoid in hand steered holder 3, hand is detached from branch
When frame 3.
Wherein, protective jacket can be integrally formed with holder 3, can also be by way of welding, bonding or other connections
It is sleeved on holder 3.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
