Current lock nut is in the time of two water pipes of docking, and cap is very poor with the sealing after connecting between cylindrical shell, causes water to infiltrate on the junction of cylindrical shell and cap, is got rusty in both junctions.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of simple, lock nut that sealing is strong rational in infrastructure.
For achieving the above object, the utility model provides following technical scheme:
A kind of lock nut, the cap that comprises cylindrical shell and removably connect with cylindrical shell both sides, it is characterized in that: described cylindrical shell comprises limit body and is positioned at the connector of limit body both sides, cap is threaded with connector, cap comprises interconnective driving section and extension, in extension and driving section, form and have active tunnel, active tunnel comprises the input chamber and the output chamber that are interconnected, between input chamber and output chamber, form and have location chamber, the curved shape of inwall of this location chamber, the diameter of location chamber from output chamber to inputting the chamber shape that tapers off, the inwall of output chamber is provided with internal thread, the inwall of input chamber comprises outer wall and Nei Yanbi, wherein, outer wall takes the form of inclined plane, the opening part of connector is provided with the detent of corresponding location chamber, the curved shape of inwall of detent, between detent and location chamber, be connected by seal, seal comprises respectively the first supporting section and the second supporting section with location chamber and seal adaptation, between the first supporting section and the second supporting section, be connected by strengthening segment, wherein, the first supporting section length is greater than the length of the second supporting section.
By adopting technique scheme, water pipe stretches in active tunnel from extension, because the location chamber in active tunnel is provided with seal with between detent, seal has improved the sealing of active tunnel greatly, and, in the installation process of seal, the first supporting section of seal is conflicted indoor at positioning chamber, the second supporting section is conflicted in detent, make in the process that is threaded more closely of cap and connector when rotariling actuate section, when seal loading is larger, cap is also just got over intensity with the connection sealing of connector, having stopped water oozes out and flow to the junction of cap with cylindrical shell.
The structure of the first supporting section and the second supporting section arranges for locating chamber and detent, therefore the curved shape of both structures, ensure the anti-pressure ability of himself, when after the first supporting section and the second supporting section and location chamber and detent adaptation, in can being fastened on, and then improve the connective stability of seal.
The utility model is further set to: described outer wall is 30 ° with respect to the interior angle of inclination along wall.
The utility model is further set to: described seal adopts integrally moulded.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, embodiment of the present utility model is described further.
A kind of lock nut, the cap 2 that comprises cylindrical shell 1 and removably connect with cylindrical shell 1 both sides, cylindrical shell 1 comprises limit body 11 and is positioned at the connector 12 of limit body 11 both sides, cap 2 is threaded with connector 12, cap comprises interconnective driving section 22 and extension 21, extension 21 and driving section 22 interior formations have active tunnel 20, active tunnel 20 comprises the input chamber 201 and the output chamber 202 that are interconnected, between input chamber 201 and output chamber 202, form and have location chamber 203, the curved shape of inwall of this location chamber 203, the diameter of location chamber 203 from output chamber 202 to input chamber 201 shape that tapers off, the inwall of output chamber 202 is provided with internal thread, the inwall of input chamber 201 comprises outer wall 20a and interior along wall 20b, wherein, outer wall 20a takes the form of inclined plane, the opening part of connector 12 is provided with the detent 10 of corresponding location chamber 203, the curved shape of inwall of detent 10, between detent 10 and location chamber 203, be connected by seal 3, seal 3 comprises respectively the first supporting section 31 and the second supporting section 32 with location chamber 203 and seal 3 adaptations, between the first supporting section 31 and the second supporting section 32, be connected by strengthening segment 33, wherein, the first supporting section 31 length are greater than the length of the second supporting section 32.
By adopting technique scheme, water pipe stretches in active tunnel 20 from extension 21, because the location chamber 203 in active tunnel 20 is provided with seal 3 with between detent 10, seal 3 has improved the sealing of active tunnel 20 greatly, and, in the installation process of seal 3, the first supporting section 31 of seal 3 is conflicted in the chamber 203 of location, the second supporting section 32 is conflicted in detent 10, make in the process that is threaded more closely of cap 2 and connector 12 when rotariling actuate section 22, seal 3 is stressed when larger, cap 2 is also just got over intensity with the connection sealing of connector 12, having stopped water oozes out and flow to the junction of cap 2 with cylindrical shell 1.
By location chamber 203 be arranged to diameter from output chamber 202 to input chamber 201 shape that tapers off, ensured the lock ability of location chamber 203 to seal 3.
The structure of the first supporting section 31 and the second supporting section 32 arranges for locating chamber 203 and detent 10, therefore the curved shape of both structures, ensure the anti-pressure ability of himself, when after the first supporting section 31 and the second supporting section 32 and location chamber 203 and detent 10 adaptations, in can being fastened on, and then improve the connective stability of seal 3.
Outer wall 20a is 30 ° with respect to the interior angle of inclination along wall 20b. In the time that outer wall 20a is 30 ° with respect to the interior angle of inclination along wall 20b, water pipe stretches into efficiency the best of active tunnel 20.
In order to reduce production costs and cost of transportation, therefore seal 3 is adopted integrally moulded.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common variation and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
