Description
Technical field:
The utility model relates to pipe joint technical field, connects more specifically to a kind of gas meter, flow meter
Head.
Background technology:
Existing gas meter connector is made up of connecting tube and attaching nut, and gas meter, flow meter is with attaching nut even
Being connected together, user can arbitrarily dismantle attaching nut and walk around gas meter, flow meter and make the actual gas of user
Amount produces and is not inconsistent with gas meter, flow meter.In order to prevent user from walking around gas meter, flow meter gas, there is multiple combustion at present
Gas meter joint is used for anti-theft anti-disassembling, and its weak point is, these anti-theft anti-disassembling gas meter connectors one
As structure complex so that production cost is of a relatively high, haves much room for improvement.
Utility model content:
The purpose of this utility model is aiming at the deficiency of prior art, and provides a kind of antitheft anti-
Tearing gas meter connector open, its simple in construction, production cost is low, and anti-theft anti-disassembling is effective.
Technology solution of the present utility model is as follows:
Anti-theft anti-disassembling gas meter connector, including connecting tube and attaching nut, connecting tube is from top to bottom
Be followed successively by threaded circular pipeline section, regular hexagon pipeline section, baffle ring be molded over lower pipe section together with constitute,
Connecting tube screw thread is formed on threaded circular pipeline section；The structure of attaching nut is, in the upper end of cylinder
Form back-up ring, the lower end external diameter of cylinder is molded guide ramp and outer bulge loop, the inwall of cylinder
On form nut thread, outer bulge loop forms outer wall draw-in groove, the profile of cylinder is positive eight limits
Shape；
The upper end of sheath forms upper end jack, and the regular hexagon pipeline section sleeve of connecting tube is at sheath
In, the inwall of sheath forms sheath draw-in groove, attaching nut's sleeve in sheath, jump ring card
Making in inwall draw-in groove, packing ring sleeve is in lower pipe section；The outer wall of sheath is circular, block card
Sleeve is in outer wall draw-in groove.
Described jump ring is fastened in inwall draw-in groove and outer wall draw-in groove.
The beneficial effects of the utility model are:
Its simple in construction, production cost is low, and anti-theft anti-disassembling is effective.

Detailed description of the invention:
Embodiment: as shown in Fig. 1 is to 5, anti-theft anti-disassembling gas meter connector, including connecting tube 1
With attaching nut 2, connecting tube 1 is from top to bottom followed successively by threaded circular pipeline section 11, regular hexagon pipe
Section 12, baffle ring 13 are constituted together with being molded over lower pipe section 14, and threaded circular pipeline section 11 becomes
Type has connecting tube screw thread；The structure of attaching nut 2 is, forms gear in the upper end of cylinder 21
Circle 22, the lower end external diameter of cylinder 21 is molded guide ramp 23 and outer bulge loop 24, cylinder 21
Inwall on form nut thread, outer bulge loop 24 forms outer wall draw-in groove 25, cylinder 21
Profile be octagon；
The upper end of sheath 3 forms upper end jack 31, the regular hexagon pipeline section 12 of connecting tube 1
Sleeve, in sheath 3, the inwall of sheath 3 forms sheath draw-in groove 32, and attaching nut 2
Sleeve is in sheath 3, and jump ring 5 is fastened in inwall draw-in groove 32, and packing ring 4 sleeve is at lower circle
On pipeline section 14；The outer wall of sheath 3 is circular, and block card 6 sleeve is in outer wall draw-in groove 25.
Described jump ring 5 is fastened in inwall draw-in groove 32 and outer wall draw-in groove 25.
Operation principle: be in state shown in Fig. 3 when the utility model installs, when people need
During the utility model to be taken apart, it is necessary to utilize spanner or clamp attaching nut 2 to be outwarded winding, and
The jump ring 5 of this utility model is stuck in inwall draw-in groove 32 and outer wall draw-in groove 25, and sheath 3 is permissible
Rotate around attaching nut 2.Usual tool wrench or clamp can only clip sheath 3, clip and protect
Set 3 rotation, can only be idle running, so cannot turn attaching nut 2, protect attaching nut 2
All the time it is connected together with gas meter, flow meter, thus prevents from usurping combustion gas, prevent from taking attaching nut and combustion apart
The connection of gas meter.
When the utility model is installed, as shown in Figure 1, before product export, jump ring 5 is stuck in inwall
In draw-in groove 32, firmly press sheath 3 downwards, make jump ring 5 drop downward into along guide ramp 23
In outer wall draw-in groove 25, the most just become the state shown in Fig. 3.
