Description
Technical Field
The utility model relates to a boiler tube assembly technical field, in particular to take formula pipeline interface structure that connects soon of spring spacer pin.
Background
Most fireplaces in the prior art adopt the screwing type pipeline interfaces, most pipeline screwing interfaces are of non-locking limiting structures, and the furnace tube can easily rotate against the potential needle in the installation process. In addition, the interface parts of the furnace tube are short, and when the upper end pipeline is installed, the furnace tube interface can rotate along with the furnace tube interface due to the fact that the furnace tube interface is not locked in a limiting mode, and when the furnace tube convex hull rotates to the notch, the furnace tube convex hull is easy to fall off. The occlusion parts of the concave-convex teeth are all in an open form, and the structure cannot be well sealed and is easy to feed water.
SUMMERY OF THE UTILITY MODEL
To the deficiencies of the prior art, the main object of the present invention is to provide a rotary pipe joint structure with a spring limit pin, which can prevent the furnace tube from rotating and falling off.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a take connect formula pipeline interface structure soon of spring spacer pin, includes the boiler tube, the boiler tube includes the furnace body, the lower part of furnace body is provided with the ring channel, be provided with the first oblique dogtooth of a plurality of on the lateral wall of ring channel, the upper portion of furnace body be provided with can insert establish in the ring channel and can with the oblique dogtooth of the first oblique dogtooth complex of a plurality of second, the mounting groove has been seted up at the top of ring channel, be provided with the spring in the mounting groove, wear to be equipped with the bayonet lock in the spring, the bayonet lock including can stretch into the kicking block that stretches out the mounting groove and can with the butt of spring butt, be provided with the flexible groove that can hold the bayonet lock on the mounting groove, the top of boiler tube be provided with a plurality of can with the depressed.
Preferably, the surface of the top block is an arc-shaped surface, and the shape of the concave groove is a kidney-shaped groove.
Preferably, the number of the mounting grooves is two.
Preferably, the diameter of the telescopic groove is the same as that of the bayonet.
The utility model discloses have following advantage for prior art, connect soon through the oblique dogtooth of the first oblique dogtooth of afterbody depressed slot and the second of head between the boiler tube, then make between the boiler tube receive an axial spring force through bayonet lock compression spring, first oblique dogtooth and the oblique dogtooth of second between two boiler tubes of connecting from top to bottom this moment interact can produce a frictional resistance. If the furnace tube is subjected to an anticlockwise torsion and the torsion is smaller than the maximum static friction resistance, the furnace tube is still static. This scheme can avoid the boiler tube installation in-process because the striking and gyration, and mounting groove and spring set up a plurality ofly can realize and can increase connection stability, also can make connect effectively to avoid rotating because of producing friction torsion in other pipeline installation behind the installation soon and lead to droing.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, a screw-on type pipeline interface structure with a spring limit pin comprises a furnace tube 1, the furnace tube 1 comprises a furnace body 2, the lower part of the furnace body 2 is provided with an annular groove 3, the side wall of the annular groove 3 is provided with a plurality of first oblique convex teeth 4, the upper part of the furnace body 2 is provided with a plurality of second oblique convex teeth 5 which can be inserted into the annular groove 3 and can be matched with the plurality of first oblique convex teeth 4, the top of the annular groove 3 is provided with an installation groove 6, a spring 7 is arranged in the installation groove 6, a bayonet 8 penetrates through the spring 7, the bayonet 8 comprises a top block 9 which can extend into the extending installation groove 6 and an abutting block 10 which can abut against the spring 7, the mounting groove 6 is provided with a telescopic groove 11 capable of accommodating a bayonet pin 8, and the top of the furnace tube 1 is provided with a plurality of concave grooves 12 capable of being abutted to the top block 9.
The utility model provides a take connect formula pipeline interface structure soon of spring 7 spacer pin, its theory of operation is, connect soon through the oblique dogtooth 5 of first oblique dogtooth 4 in afterbody depressed groove 12 and the second of head between the boiler tube 1, then receive an axial spring 7 power between the boiler tube 1 through bayonet lock 8 compression spring 7 messenger boiler tube 1 between the boiler tube 1, the first oblique dogtooth 4 and the oblique dogtooth 5 interact of second between two boiler tubes 1 of connecting from top to bottom this moment can produce a frictional resistance. If the furnace tube 1 is subjected to an anticlockwise torsion and the torsion is smaller than the maximum static friction resistance, the furnace tube 1 is still static. This scheme can avoid 1 installation of boiler tube in-process because the striking and gyration, and mounting groove 6 and spring 7 set up a plurality ofly can realize and can increase connection stability, also can make connect effectively to avoid rotating because of producing friction torsion in other pipeline installation behind the installation soon and lead to droing.
Preferably, the surface of the top block 9 is an arc-shaped surface, and the concave groove 12 is a kidney-shaped groove. The advantage of setting up like this can make kidney slot and kicking block 9 counterpoint faster, and the assembled is more smooth and easy.
Preferably, the number of the mounting grooves 6 is two. The number of the mounting grooves 6 is two, that is, the installation grooves can be prevented from rotating and can be reduced.
Preferably, the diameter of the telescopic groove 11 is the same as the diameter of the bayonet. The advantage of this arrangement is that the telescopic slot 11 can act as a guiding and limiting position.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
