Abstract
A kind of novel thimble protection sleeve pipe; the thimble is a slender cylinder, and including sheath assembly, described sleeve pipe component includes first sleeve and the second casing; the first sleeve sets vaulted cylindrical structure for one end, and the first sleeve is internally provided with the first cylindrical hole communicated with the external world；Second casing includes a cylindrical tube, and one end of the cylindrical tube is provided with disk, the connecting hole communicated with the second cylindrical hole inside the cylindrical tube is provided in the middle part of the disk；The cylindrical tube dismountable moving of second casing is arranged in first cylindrical hole, and the thimble is arranged on by the connecting hole dismountable moving in second cylindrical hole.The utility model forms duplicate protection by the cooperation of first sleeve and the second casing to thimble, the ejecting product that thimble is allowed to stablize, also the mold damage no longer due to fracture.
Description
Technical field
The utility model is related to a kind of casings, and in particular to a kind of novel thimble protection sleeve pipe.
Background technology
At present, it when making plain screw, needs to use solid top stick, and when long spiro nail is made, it is also necessary to
Protection sleeve pipe is used, general protection sleeve pipe is simple single protection sleeve pipe, still will appear disconnected thimble when in use
Phenomenon, since the thimble in protection sleeve pipe is thinner, when rocker arm shaft is ejected stress and activity it is ordinary, so as to cause rocking arm axial plane
Impaired, protection sleeve pipe cannot protect thimble well, and when thimble is withdrawn into certain distance can deviate down, rocker arm shaft ejection
Shi Yinwei thimbles can just not push up directly disconnected, and mold also can be by different degrees of damage.
It is therefore desirable to design a kind of novel thimble protection sleeve pipe to solve the above problems.
Invention content
To overcome above-mentioned deficiency of the prior art, the utility model aim is to provide a kind of novel thimble protective case
Pipe.
In order to achieve the above objects and other related objects, technical solution provided by the utility model is：A kind of novel top
Needle protective canula, the thimble are a slender cylinder, and including sheath assembly, described sleeve pipe component includes first sleeve and second set
Pipe, the first sleeve set vaulted cylindrical structure for one end, and the first sleeve is internally provided with what is communicated with the external world
First cylindrical hole；Second casing includes a cylindrical tube, and one end of the cylindrical tube is provided with disk, is set in the middle part of the disk
It is equipped with the connecting hole communicated with the second cylindrical hole inside the cylindrical tube；The cylindrical tube dismountable moving of second casing
It is arranged in first cylindrical hole, the thimble is arranged on second cylindrical hole by the connecting hole dismountable moving
It is interior.
Preferably technical solution is：The diameter of the disk is more than the diameter of the first sleeve.
Preferably technical solution is：The connecting hole is bellmouth.
Preferably technical solution is：The wall thickness of the first sleeve is 6-8mm.
Preferably technical solution is：The outer wall of the first sleeve is provided with several stripeds.
Since above-mentioned technical proposal is used, the utility model this have the advantage that compared with prior art：
The utility model forms thimble duplicate protection, thimble is backward by the cooperation of first sleeve and the second casing
When moving back, the second casing shrinks back together, simultaneously because the forced area of the second casing is larger, it will not be to it when hitting rocker arm shaft
There is any influence, rocker arm shaft is directly withstood on when ejecting on the second casing, and the thimble in the second casing is protected well, no longer
It is broken, the ejecting product that thimble is allowed to stablize, also the mold damage no longer due to fracture.
Description of the drawings
Fig. 1 is the utility model overall schematic.
Fig. 2 is the first sleeve schematic diagram.
Fig. 3 is second sleeve schematic diagram.
In the figures above, thimble 1, first sleeve 2, the second casing 3, dome 4, the first cylindrical hole 5, cylindrical tube 6, disk 7,
Second cylindrical hole 8, connecting hole 9, striped 10.
Specific embodiment
Illustrate the embodiment of the utility model by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
Please refer to Fig.1 ~ Fig. 3.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to
Coordinate the revealed content of specification, so that those skilled in the art understands and reads, be not limited to the utility model
Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size
Adjustment, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model
Revealed technology contents are obtained in the range of covering.Meanwhile in this specification it is cited as " on ", " under ", " left side ",
The term on " right side ", " centre " and " one " etc. is merely convenient to the clear rather than enforceable to limit the utility model of narration
Range, relativeness are altered or modified, enforceable when being also considered as the utility model in the case where changing technology contents without essence
Scope.
As shown in Fig. 1 ~ Fig. 3, a kind of novel thimble protection sleeve pipe, the thimble 1 is a slender cylinder, including casing
Component, sheath assembly include 2 and second casing 3 of first sleeve, and first sleeve 2 is equipped with the cylindrical structure of dome 4 for one end, the
Sleeve 2 is internally provided with the first cylindrical hole 5 communicated with the external world；Second casing 3 includes a cylindrical tube 6, one end of cylindrical tube 6
Disk 7 is provided with, 7 middle part of disk is provided with the connecting hole 9 communicated with the second cylindrical hole 8 inside cylindrical tube 6；Second casing 3
6 dismountable moving of cylindrical tube be arranged in the first cylindrical hole 5, thimble 1 is arranged on by 9 dismountable moving of connecting hole
In two cylindrical holes 8.
Preferred embodiment is：The diameter of disk 7 is more than the diameter of first sleeve 2.During dismounting, it can scratch and resist disk 7,
It is taken off from first sleeve 2, easy disassembly is easy to operate.
Preferred embodiment is：As shown in figure 3, connecting hole 9 is bellmouth.With guiding role, convenient for inserting for thimble 1
Enter.
Preferred embodiment is：As shown in Fig. 2, the wall thickness of first sleeve 2 is 6-8mm.While material is saved
