Abstract
The utility model discloses a rainproof anti-explosion movable joint, which comprises a first joint and a second joint. The external end of the first joint is equipped with thread, the first joint is fastened via a movable nut connected to the second joint via thread, a sealing ring is arranged between the first joint and the second joint, and the second joint can upwards cover a skirt edge of a lamp leading-in connector, thereby preventing rainwater entering the movable joint and the lamp leading-in connector connected with the same. The rainproof anti-explosion movable joint is reasonable in structure and utilizes the threads at two ends of the joint to connect, and the movable nut and the thread which are arranged on the middle portion of the joint are used for rotating to achieve connecting stably without rotating a lamp pole or a lamp cap. Three connection passages from inside to outside of the movable joint all utilize a structural form meeting anti-explosion requirements, thereby achieving anti-explosion property. Parts used for connection utilize a structure of 'upper parts covering lower parts', namely, the first joint covers the second joint, the second joint covers the lamp leading-in connector, and a necessary position utilizes a sealing ring structure to achieve waterproof property integrally.
Description
Technical field:
The utility model relates to a kind of joint.
Background technology:
The existing jointing that is used for explosion-proof lamp and outdoor lamp stand owing to reasons such as structures, can not have explosion-proof water-resistant performance simultaneously.
Summary of the invention:
It is a kind of rational in infrastructure, easy to use that the purpose of this utility model is to provide, and when guaranteeing explosion-proof performance, prevents that rainwater from entering articulation and the rainproof explosion-proof articulation of the light fixture intake that connected.
Technical solution of the present utility model is:
A kind of rainproof explosion-proof articulation, it is characterized in that: comprise that outboard end is provided with first joint of screw thread, second joint, the nut of living blocks first joint, and by being threaded on second joint, between first, second joint sealing ring is set, the shirt rim that can cover light fixture introducing interface from top by second joint prevents the light fixture intake that rainwater enters articulation and connected.
Described sealing ring is positioned on second joint, and first joint is pressed on the sealing ring.
The utility model is rational in infrastructure, utilizes the screw thread at joint two ends to connect, and the middle part nut of living is used for rotation, reaches need not rotate lamp stand or lamp holder just can play the fastening performance of connection; To three connecting paths of outside, all adopt the version that satisfies the flame proof requirement from the inside of articulation, reach the performance of flame proof; Each part that is used to connect adopts the structure of " under the loam cake ", that is, first joint covers second joint, and second joint covers the light fixture intake, and adopts ring structure at necessity place, comes integral body to reach water-resistant performance.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is user mode figure of the present utility model.
