Abstract
The utility model discloses a kind of adapter sleeve, its drip irrigation device comprises adapter sleeve body, described adapter sleeve body one end is threaded ends, the other end is free end, the outer circumference surface of described adapter sleeve is installed with annular lug, annular lug stretches out near threaded ends side formation reinforcement, and described reinforcement narrows gradually from annular lug to the extreme direction that is threaded and outer surface is arc-shaped.The vibrational power flow of the utility model annular lug rationally makes annular lug not fragile.
Description
Technical field
The utility model relates to cable connection area, and more particularly, it relates to a kind of adapter sleeve.
Background technology
After power cable lays, in order to become a continuous print circuit, each section of line must connect as a whole, make circuit unobstructed, also should ensure that cable socket is connected with the reliable of equipment simultaneously, in practice of construction process, usually adopt joint sleeve to process, the joint sleeve being positioned at cable line middle part becomes intermediate connecting sleeve, and the joint sleeve of circuit two end is called terminal adapter sleeve.
At present; a kind of adapter sleeve on market; one end is threaded ends; the other end is free end; cable has certain pulls power; thus having outside pulling force to adapter sleeve, the outer circumference surface of adapter sleeve is for this reason installed with the annular lug preventing adapter sleeve from easily deviating from, and such setting simultaneously also protects screw thread to a certain extent.But annular lug is independently arranged, and does not arrange boss, cause like this annular lug after long-term use or difference variation is larger time, larger deformation can occur, cause structural strength to change, even come off, permanent use is easily damaged.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of makes with boss the adapter sleeve that annular lug is not fragile or come off.
For achieving the above object, the utility model adopts following technical scheme, comprise adapter sleeve body, described adapter sleeve body one end is threaded ends, the other end is free end, the outer circumference surface of described adapter sleeve is installed with annular lug, and annular lug stretches out near threaded ends side formation reinforcement, and described reinforcement narrows gradually from annular lug to the extreme direction that is threaded and outer surface is arc-shaped.
Preferably, annular lug is provided with breach near free end side, the cross section semicircular in shape of described breach.
Preferably, the inner peripheral surface outwardly convex of adapter sleeve body is formed and abuts block, and described abutting block is positioned in the middle part of adapter sleeve body.
Preferably, abut block and be provided with chamfering structure near free end side.
The utility model hinge structure is compared to be had: annular lug stretches out near threaded ends side formation reinforcement, reinforcement narrows gradually from annular lug to the extreme direction that is threaded and outer surface is arc-shaped, arranging like this plays booster action to annular lug, when annular lug is stressed, reinforcement plays a supportive role, outer surface is that the reinforcement of arc-shaped has better peptizaiton to power, ensure that annular lug and reinforcement are not easy to damage, and reinforcement and annular lug are wholely set, can prevent annular boss from coming off.

Fig. 1 is that adapter sleeve partly cuts open schematic diagram;
Fig. 2 is that adapter sleeve partly cuts open schematic diagram two;
Fig. 3 is A portion enlarged drawing in Fig. 2.
Reference numeral: 1, free end, 2, annular lug, 3, reinforcement, 4, threaded ends, 5, abut block, 6, breach.
Embodiment
With reference to accompanying drawing, the utility model adapter sleeve embodiment is described further.
A kind of adapter sleeve, comprise adapter sleeve body, described adapter sleeve body one end is threaded ends 4, the other end is free end 1, the outer circumference surface of described adapter sleeve is installed with annular lug 2, annular lug 2 stretches out near threaded ends 4 side and forms reinforcement 3, reinforcement 3 narrows gradually from annular lug 2 to threaded ends 4 direction and outer surface is arc-shaped, arranging like this plays booster action to annular lug 2, when annular lug 2 is stressed, reinforcement 3 plays a supportive role, outer surface is that reinforcement 3 pairs of power of arc-shaped have better peptizaiton, ensure that annular lug 2 and reinforcement 3 are not easy to damage.
Annular lug 2 is provided with breach 6 near free end 1 side, the cross section semicircular in shape of breach 6, and when annular lug 2 is subject to the force of inwardly extruding, annular lug 2 has a space cushioned, and avoids annular lug 2 easily to damage.
The inner peripheral surface outwardly convex of adapter sleeve body is formed and abuts block 5, and abut block 5 and be positioned in the middle part of adapter sleeve body, such being provided with helps block the cable penetrated in adapter sleeve, makes cable be not easy, and ensures the firm of connection.
Abut block 5 and be provided with chamfering structure near free end 1 side, facilitate passing of cable like this, avoid easily blocking, increase work efficiency.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to the above embodiments, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
