[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-5 A bus duct shell and bus duct that are easy to assemble, including a bus duct 1, the bus duct 1 includes a first shell 2 and a second shell 3, the first shell 2 is connected to a first connecting block 4, a screw 5 is arranged in the first connecting block 4, a sleeve 6 is connected to one end of the first connecting block 4, a conical slider 7 is slidably installed in the sleeve 6, one end of the conical slider 7 is in contact with one end of the screw 5, a plurality of balls 8 are slidably installed on the outer wall of the sleeve 6, and the ends of the balls 8 located in the sleeve 6 are in contact with the inclined surface of the conical slider 7, a second connecting block 9 is connected to the second shell 3, the second connecting block 9 corresponds to the first connecting block 4, a socket 10 is provided on the second connecting block 9, the sleeve 6 is located in the socket 10, a conical hole 11 is provided at one end of the socket 10, and the ends of the plurality of balls 8 located outside the sleeve 6 are all abutted against the inner wall of the conical hole 11.
[0023] During assembly, align the sleeve 6 with the socket 10 and insert it into the second connecting block 9, and screw the screw 5 so that the screw 5 pushes the conical slider 7 to move in the sleeve 6. The inclined surface of the conical slider 7 contacts the ball 8 and pushes the ball 8 outward to expand, so that the ball 8 rests on the inner wall of the conical hole 11, thereby realizing the connection between the sleeve 6 and the second connecting block 9. Conversely, the fixed connection between the first connecting block 4 and the second connecting block 9 is realized, and then the connection between the first shell 2 and the second shell 3 is realized, and the assembly of the bus duct 1 is realized. Compared with the prior art, the number of turns of bolt tightening is effectively reduced, the assembly efficiency is improved, and the assembly of the bus duct 1 is more convenient. Through the cooperation between the outward expansion of the ball 8 and the conical hole 11, the first connecting block 4 and the second connecting block 9 produce a mutual extrusion effect, thereby improving the tightness after the connection between the first shell 2 and the second shell 3, and improving the connection effect.
[0024] Specifically, in this embodiment, a threaded hole 12 is opened in the first connecting block 4, and the screw 5 is threadedly connected in the threaded hole 12, so that the screw 5 generates axial movement while being screwed, pushing the conical slider 7 to move, and improving the stability of the connection between the screw 5 and the first connecting block 4.
[0025] Specifically, in this embodiment, a hexagonal hole 13 is formed on one end of the screw 5 away from the conical slider 7, so as to facilitate the screwing operation of the screw 5 using a tool.
[0026] Specifically, in this embodiment, the maximum outer diameter of the tapered slider 7 is the same as the inner diameter of the sleeve 6 , so that the tapered slider 7 can stably slide in the sleeve 6 .
[0027] Specifically, in this embodiment, one end of the sleeve 6 is closed, and a spring 14 is connected between the inner wall and the conical slider 7. The elastic force of the spring 14 enables the screw 5 to push the conical slider 7 in the direction of retraction of the screw 5 when the screw 5 is retracted, thereby facilitating the inward retraction of the ball 8.
[0028] Specifically, in the present embodiment, a ball sliding hole 15 is opened on the outer wall of the sleeve 6. The ball sliding hole 15 is located at one end of the outer wall of the sleeve 6 and has a hole diameter slightly smaller than the diameter of the ball 8, and is located at one end of the inner wall of the sleeve 6 and has the same diameter as the ball 8. The ball sliding hole 15 provides space for the ball 8 to expand and retract, and prevents the ball 8 from detaching from the outer wall of the sleeve 6.
[0029] Specifically, in this embodiment, the aperture of the jack 10 is the same as the outer diameter of the sleeve 6, so that the sleeve 6 and the jack 10 are more matched, and the sliding of the sleeve 6 after insertion is limited, thereby improving the connection effect.
[0030] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
