Locking member, for, to after contact, the plug and the pedestal being locked in the sealing ring and the pedestal
It fastens.
The utility model embodiment in terms of existing technologies, since sealing structure includes the base with a basal plane
Seat, blind cover and sealing ring, wherein pedestal opens up centre bore, and the position that plug is connected with end cap along the direction perpendicular to basal plane
It is equipped with card slot, sealing ring is sheathed in card slot, thus, in actual installation process, before blind cover is anchored on pedestal by locking member,
Sealing ring is contacted with the basal plane of pedestal first, after then being compressed blind cover by locking member, sealing ring is made to be squeezed and generate shape
Become, the centre bore of equipment base is sealed.Therefore, which can not only effectively improve blind cover to the leakproofness of pedestal
It can, moreover it is possible to facilitate the installation of blind cover.
In addition, the centre bore along hole depth direction successively includes: the first hole section, is connected with first hole section and coaxial
Second hole section, and the aperture of first hole section is from the side being connected with the basal plane to the side being connected with second hole section
It is gradually reduced, the hole wall of first hole section is of an inclined plane, and the sealing ring is used to resist the base of the pedestal in the end cap
The hole wall of first hole section is resisted while face.Blind cover is plugged so as to convenient, also, end cap and the second hole section
Sealing ring is fixed in the first hole section, thus can further improve the sealing performance of sealing structure.
In addition, the slot bottom of the card slot is arc surface, the section of the sealing ring is circle.
In addition, the plug and the end cap are integrally formed.To can further improve the stability of blind cover.
In addition, the plug and the end cap are metalwork.
In addition, the sealing ring is compliant member.
In addition, the sealing ring is rubber ring or silica gel ring.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, in order to make the reader understand this application better, many technical details are proposed.But even if without these skills
The required guarantor of each claim of the application also may be implemented in art details and various changes and modifications based on the following respective embodiments
The technical solution of shield.
The first embodiment of the utility model is related to a kind of sealing structure.As shown in Figure 1, Figure 2, Figure 3 shows.The sealing structure
Including pedestal 1, blind cover 2, sealing ring 3 and locking member.Wherein, pedestal 1 has a basal plane, and opens up along the direction perpendicular to basal plane
Centre bore 11, meanwhile, blind cover 2 includes plug 21 and the end cap 22 for being surrounded on 21 surrounding of plug, wherein plug 21 is in insertion
In heart hole 11, and end cap 22 is used to resist the basal plane of pedestal 1.Specifically, card slot 211, and the card slot are equipped on plug 21
211 are opened in the position that plug 21 is connected with end cap 22, and sealing ring 3 is mounted in card slot 211, and resists end cap 22, thus logical
It crosses card slot 211 and can facilitate and sealing ring 3 is installed.In addition, in the present embodiment, the slot bottom of card slot 211 is arc surface, and
The section of sealing ring 3 is circle.The installation and removal of sealing ring 3 can thus be further facilitated.In actual use, first will
Plug 21 is inserted into the first hole section 111, and resists basal plane by end cap 22, then, is carried out using locking member to end cap 22 and pedestal 1
It is locked, so that sealing ring 3 generates deformation, and then effectively pedestal 1 is sealed.In actual use, locking member
Bolt can be used, and open up threaded hole on end cap 22 and pedestal 1 respectively, so as to be threadedly coupled by bolt with threaded hole,
It realizes to being locked between blind cover 2 and pedestal 1, sealing ring 3 is squeezed and deformed, and then realize the centre bore 11 to pedestal 1
It is sealed.It is of course also possible to be the buckle of other forms, as long as can be realized solid to the locking between plug 21 and pedestal 1
It is fixed.
Through the above it is not difficult to find that since the sealing structure includes pedestal 1, blind cover 2 and sealing ring 3.Blind cover 2 is blocked up
First 21 for being inserted into centre bore 11, and the basal plane of pedestal 1 is resisted by end cap 22, and sealing ring 3 is set on plug 21 and resists
End cap 22, and plug 21 and pedestal 1 can be locked by locking member after sealing ring 3 is in contact with pedestal 1.To
When needing to be sealed sealing structure, plug 21 can be protruded into the second hole section 112 first, and make sealing ring 3 and pedestal 1
Basal plane offset, then, end cap 22 is compressed by locking member, so that sealing ring 3 is generated deformation, thus can realize on pedestal 1
The sealing of centre bore 11.
In addition, in the present embodiment, centre bore 11 successively includes the first hole section 111 and the first hole section along hole depth direction
111 are connected and the second hole sections 112 for being coaxially disposed, and the aperture of the first hole section 111 is from the side being connected with pedestal 1 to second
The connected side of hole section 112 is gradually reduced, also, the hole wall of the first hole section 111 is inclined-plane, and when end cap 22 resists pedestal 1
When basal plane, sealing ring 3 resists the hole wall of the first hole section 111.Since the side wall of the first hole section 111 is inclined-plane, thus can facilitate blind
The plug of lid 2, also, sealing ring 3 is fixed in the first hole section 111 by end cap 22 and the second hole section 112, thus can further mention
The sealing performance of highly dense seal structure.
In addition, it is noted that in order to further facilitate installation and removal blind cover 2, plug 21 and the second hole section 112 it
Between clearance fit, and sealing ring 3 be compliant member.Also, in the present embodiment, plug 21 and end cap 22 can be disposed as gold
Belong to part, and sealing ring 3 is rubber ring or silica gel ring, certainly, in actual use, plug 21 and sealing cover 22 can also be by
Other materials combination is made, and the compliant member of other forms can also be used in sealing ring 3, does not limit specifically herein.In addition, being
The sealing performance of sealing structure is further increased, plug 21 and end cap 22 are integrally formed, certainly, in practical application, plug
21 may be alternatively provided as the form being detachably connected with end cap 22.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific implementation of the utility model
Example, and in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit of the utility model
And range.
