Description

A kind of lamp decoration tubing no-welding self-tightening connectivity kit
Technical field
The utility model is related to a kind of lamp decoration tubing no-welding self-tightening connectivity kit.
Background technology
At present in lamp decoration production, tubing connection is typically all weldering nut or screw on tubing.Welding and processing weldering Mouth will spend very big man power and material.Production efficiency and quality are largely constrained, improves production cost.Welding needs Oxygen, acetylene, welding rod and scaling powder are consumed, processing weld bond needs to polish and pickling, and consumption is big, has shadow to environment and worker It rings.
Utility model content
The utility model devises a kind of lamp decoration tubing no-welding self-tightening connectivity kit in view of the deficiencies of the prior art.
The utility model is in order to achieve the above object, using following scheme:A kind of lamp decoration tubing no-welding self-tightening connectivity kit, Including screwed pipe, locking sleeve and nut, the screwed pipe passes through the locking sleeve, and the nut is matched somebody with somebody with the screwed pipe It closes, the front end of the screwed pipe has truncated cone-shaped convex block, described smaller one end of truncated cone-shaped bump diameter and the screwed pipe Front end is fixedly connected, and the locking sleeve is rectangular parallelepiped structure, and through hole one, the locking are equipped with through its upper and lower surface 4 sides of casing are equipped with through hole two, and the through hole two is connected with the through hole one, and item is provided with along its center line on the side V notch v, one end of described v notch v extend to the through hole two, and the other end extends to the lower surface of the locking sleeve.
Further, the through hole two is closer to the upper surface of the locking sleeve, i.e., through hole two is away from the lock sleeve The lower surface of pipe makes a v notch v have the length of bigger, preferably to strut.
Further, the extension line of described v notch v passes through the center of circle of the through hole two.
Compared to the prior art the utility model, has the following advantages that and advantageous effect:It is simple in structure, it is easy to use, make Traditional welding can be substituted with the present apparatus, substantially increase production efficiency, reduce cost.
Description of the drawings
Fig. 1 is each component exploded view of the utility model;
Fig. 2 is the utility model combination diagram;
Fig. 3 is the utility model locking sleeve sectional view;
Fig. 4 is the utility model screwed pipe sectional view.
Specific embodiment
With reference to Fig. 1 to Fig. 4, a kind of lamp decoration tubing no-welding self-tightening connectivity kit, including screwed pipe 1, locking sleeve 2 and spiral shell Mother 3, the screwed pipe 1 pass through the locking sleeve 2, and the nut 3 coordinates with the screwed pipe 1, the outer circumference surface of screwed pipe 1 External screw thread is equipped with, the front end of the screwed pipe 1 has truncated cone-shaped convex block 11, described smaller one end of 11 diameter of truncated cone-shaped convex block It is fixedly connected with the front end of the screwed pipe 1, as shown in figure 3, the locking sleeve 2 is rectangular parallelepiped structure, through its upper surface Be equipped with through hole 1 with lower surface, 4 sides of the locking sleeve 2 are equipped with through hole 2 22, the through hole 2 22 with it is described Through hole 1 connects, and is provided with a v notch v 23 along its center line on the side, and one end of described v notch v 23 extends to described Through hole 2 22, the other end extend to the lower surface of the locking sleeve 2.
The through hole 2 22 is closer to the upper surface of the locking sleeve 2, i.e., through hole 2 22 is away from the locking sleeve 2 Lower surface makes a v notch v 23 have the length of bigger, and in stress, 4 sides are easier to strut to outside.The bar shaped lacks The extension line of mouth 23 passes through the center of circle of the through hole 2 22, and v notch v 23 lacks bar shaped parallel to the central axes of locking sleeve 2 23 both sides of mouth strut the symmetrical distribution in part, realize uniform force.
In addition, as shown in figure 4, hollow structure may be employed in screwed pipe 1, while some strength is ensured, that is, spiral shell is tightened Screwed pipe 1 will not be because of crimp, preferably to save material when female.The present apparatus is made of metal, such as iron, machine-shaping After can further electrogalvanizing handle, prevent from getting rusty.
In use, as shown in Fig. 2, by screwed pipe 1 through locking sleeve 2, a lamp decoration is stretched into the part of truncated cone-shaped convex block 11 In the tube wall of tubing, the other end of screwed pipe 1 is connected with other parts by nut 3, tightens nut 3, truncated cone-shaped convex block 11 to 2 contract of locking sleeve, and then outwardly against locking sleeve 2 inside locking sleeve 2, it is located at the part of a v notch v 23 It opens, acts on tube wall, have the function that be fixedly connected.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model technical principle is not departed from, several improvement and modification can also be made, these change The scope of protection of the utility model is also should be regarded as into modification.
