The utility model adopts the technical proposal that: a joint sleeve, comprising: the device comprises a tubular main body, a handle and a handle, wherein one end of the main body is a closed end, and the other end of the main body is an open end; at least one pair of elastic arc-shaped bulges is arranged in the main body, and each pair of arc-shaped bulges comprises two arc-shaped bulges which are oppositely arranged.

Further, the body increases in size from the closed end to the open end.

Further, a welding point of the motor is inserted into the main body from the opening end of the main body, the diameter of the welding point is D, and the distance between the two oppositely arranged arc-shaped protrusions is 0.6D to 0.9D.

Preferably, the main body comprises a pipe wall, and the pipe wall is inwards recessed to form the arc-shaped bulge.

Preferably, the wall thickness of the tube wall is 0.3 mm.

Preferably, the joint sleeve is made of nylon.

Preferably, the arcuate projection comprises a smooth arcuate surface.

Preferably, two pairs of arc-shaped protrusions are arranged in the main body at intervals.

An electric machine comprising the joint sleeve.

An air conditioner comprises the motor.

Compared with the prior art, the utility model discloses in set up at least a pair of arc-shaped protrusion that has elasticity in the tubulose main part, the solder joint passes the arc-shaped protrusion and is locked in the main part, in the process of dismantling, installing and using, the arc-shaped protrusion can not cause the damage to the solder joint, and then provides effective protection to the solder joint; meanwhile, the welding spot is convenient to disassemble and assemble, the structure of the main body cannot be damaged, and the welding spot can be repeatedly utilized.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for the embodiments or the prior art descriptions will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without inventive labor.

FIG. 1 is a schematic diagram of a cross-sectional structure of a middle joint sleeve according to the present invention;

fig. 2 is a schematic sketch of the three-dimensional structure of the middle joint sleeve of the present invention.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and examples.

The utility model provides a joint sleeve, as shown in fig. 1, 2, it mainly includes a flat tubulose main part 1, and the one end of main part 1 is the blind end, and the other end is the open end, and the size of main part 1 is for progressively increasing from the blind end to the size of open end, wholly is the toper, makes things convenient for in solder joint 2 that motor end of a thread and power cord formed inserts main part 1 from the open end of main part 1, and main part 1 plays the effect of protection solder joint 2.

In order to fix solder joint 2 in main part 1, set up two pairs in main part 1 and have elastic arc arch 3, every arc arch 3 all includes the arc arch 3 of two relative settings because the setting of arc arch 3, need exert force and push into arc arch 3 to the space between the blind end in, just installed main part 1 with solder joint 3 in, under the effect of arc arch 3, solder joint 2 can not drop from main part 1 by oneself when the transport shifts or motor operation vibrates.

Meanwhile, the surfaces of the arc-shaped protrusions 3 are arc-shaped, so that the surfaces of the welding spots 2 cannot be damaged or are extremely damaged in the process of disassembling or inserting the welding spots 2, and the welding spots 2 have certain moving space in the pipe after assembly is finished, so that the arc-shaped protrusions 3 can well play a role in reducing rubbing, and particularly have a better protection effect compared with an inclined blocking arm; simultaneously, when spot check inspection solder joint quality, can directly part with hand (hold) sleeve pipe and solder joint, the structure of joint sleeve pipe can not produce destruction with the dress of dismantling of joint sleeve pipe, consequently the sleeve pipe of this application can reuse, material saving.

The arc-shaped bulge 3 is provided with a smooth arc-shaped surface, so that the welding spot 2 is inserted into the pipe from the opening of the main body 1, the friction is smaller, the damage to the welding spot is smaller, and the labor is saved;

preferably, the welding point 2 is generally spherical, and if the diameter is D, the minimum distance between two arc-shaped protrusions 3 between each pair of arc-shaped protrusions 3 is 0.6D to 0.9D, so that the welding point is clamped in the sleeve to prevent the welding point 2 from falling out.

In this embodiment, the pipe wall of the main body 1 is 0.3mm, the arc-shaped protrusion is a protrusion formed by inwards recessing the pipe wall of the main body 1 to form a thin wall shape, so that the arc-shaped protrusion 3 has elasticity, the welding point 2 can conveniently pass through the protrusion, and the wall thickness of the arc-shaped protrusion 3 is consistent with that of the pipe wall of the main body 1 and is also 0.3 mm.

Preferably, the body 1 is an insulating material having elasticity, such as nylon.

In addition, this application has still provided one kind and has included the utility model provides a joint sleeve's motor and an air conditioner including the motor in this application to the job stabilization nature that makes motor and air conditioner is better.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
