Abstract
The utility model discloses a key ring structure on password theftproof gas meter connector, inhale the combination through magnetism to form including 2 key pieces mutually, the inner wall of key piece is the four corners limit second magnet steel and third magnet steel are installed respectively to the both ends of key piece the first magnet steel of inner wall mid-mounting, when 2 second magnet steel, the third magnet steel magnetism that the key piece set up through both ends attract mutually together, form octagonal limit cavity in the key ring. The utility model discloses can solve the weak point that exists among the prior art, the unblock is very convenient nimble.
Description
Technical Field
The utility model relates to a key ring structure on password theftproof gas table connects.
Background
The joint before the theftproof gas meter is the coupling that the gas meter links to each other between air supply pipeline and the user, this joint all is that gas company installs specially, do not allow the user to open, consequently gas company installs various anti-theft devices such as lead sealing additional on coupling nut, if the user unpacks apart privately, let it unable resume, play the effect of opening traceably privately, common use have install the lead sealing on coupling nut, distinguishable mark is beaten with specialized tool, install easily crowded broken special theftproof cover outward at coupling nut additional, it opens to crowd broken theftproof cover with special hydraulic tong during the opening.
At present, the anti-theft gas joint on the market is complex in structure and troublesome in installation and unlocking; the key ring structure does not appear in the existing market, so the applicant provides further improvement on the basis, designs a key ring structure on the password anti-theft gas meter connector, and is very convenient and flexible to unlock so as to meet the requirements of the existing market.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome current defect, provide a key ring structure on password theftproof gas table connects, the unblock is very convenient nimble.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a key ring structure on password theftproof gas table connects which characterized in that: including 2 key pieces inhale the combination mutually through magnetism and form, the inner wall of key piece is the four corners limit second magnet steel and third magnet steel are installed respectively to the both ends of key piece the first magnet steel of inner wall mid-mounting is when 2 key pieces inhale mutually through second magnet steel, the third magnet steel magnetism that both ends set up, form eight octagonal edge cavities in the key ring.
It is further preferred that the outer wall of the key blade is a threaded wall.
Preferably, the key blade has a plurality of numbers on an end surface thereof.
Compared with the prior art, the utility model discloses the beneficial effect who reaches is:
the utility model discloses a 2 key pieces are inhaled the combination mutually through magnetism and are formed, the inner wall of key piece is the four corners limit second magnet steel and third magnet steel are installed respectively to the both ends of key piece the first magnet steel of inner wall mid-mounting, when 2 key pieces are inhaled mutually through second magnet steel, the third magnet steel magnetism that both ends set up, form octagonal limit cavity in the key ring, the utility model discloses as long as pull the theftproof lid upwards after password theftproof gas meter connects and gas table is connected and is installed, the magnet steel falls into the theftproof inslot, has just so deadlocked.
When the unlocking is needed, the key ring is sleeved outside the anti-theft cover, the magnetic steel is pushed into the coded magnetic steel mounting hole from the anti-theft slot through the homopolar repulsion of the magnetic steel, and the unlocking is realized. Therefore, the structure is very convenient to unlock, and the principle that the same magnetic poles repel each other is utilized to realize easy unlocking.
Therefore, the utility model discloses can solve the weak point that exists among the prior art, the unblock is very convenient nimble.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in fig. 1-4, the utility model discloses a key ring structure on password theftproof gas meter connects, its characterized in that: including 2 key blade 1 and inhale the combination mutually through magnetism and form, the inner wall of key blade 1 of institute is the four corners limit, installs second magnet steel 2 and third magnet steel 3 respectively at the both ends of key blade 1 the first magnet steel 4 of inner wall mid-mounting, when 2 key blade 1 is inhaled mutually through second magnet steel 2, the 3 magnetism of third magnet steel that both ends set up, form eight corners limit cavities in the key ring, wherein first magnet steel 4 quantity with the theftproof cover 5 on magnet steel 6 the same in quantity, first magnet steel 4 is the same towards the magnetic pole of outer end and magnet steel 6 towards the inner end magnetic pole, the outer wall of key blade is the screw thread wall, the key blade terminal surface has a plurality of figures.
The utility model discloses when the installation was stolen, as long as after being connected the installation with the gas table key ring structure on password theftproof gas meter connector, 5 upwards draw the theftproof lid, magnet steel 6 falls into the theftproof inslot, has just so deadlocked. When needing the unblock, as long as cup joint the key ring in the outside of shield 5, when first magnet steel 4 and magnet steel 6 want to correspond, through homopolar repulsion, in the password magnet steel mounting hole is pushed into from the theftproof groove with magnet steel 6, realize the unblock.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
