The specific implementation mode is as follows:
the utility model will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 3, the utility model relates to a quick-plugging connecting rod, which comprises a rod 1, a connector 3 and a connecting seat 4. The connector 3 and the connecting seat 4 are fixed on the two rod pieces 1 through rivets 2, the connector 3 is inserted into the connecting seat 4, a locking groove 31 is arranged on the outer circumferential wall of the connector 3, a plurality of steel balls 41 and a positioning sleeve 42 are arranged on the outer wall of the connecting seat 4, the steel balls 41 are arranged along the circumferential direction of the connecting seat 4, and the positioning sleeve 42 is sleeved on the connecting seat 4 and can move along the axial direction of the connecting seat 4.
The positioning sleeve 42 pushes the steel ball 41 into the locking groove 31, so that the connector 3 is connected with the connecting seat 4, and at this time, the connector 3 cannot be pulled out from the connecting seat 4.
The positioning sleeve 42 is axially moved to separate the positioning sleeve 42 from the steel ball 41, and at this time, the connector 3 is pulled outwards, so that the connector 3 can be pulled out from the connecting seat 4.
In order to facilitate the installation of the steel balls 41 on the connecting seat 4, a plurality of through holes 40 are arranged on the circumferential wall of the connecting seat 4, one steel ball 41 is placed in each through hole, the steel ball 41 extends into the inner cavity of the connecting seat 4 through the through hole, and the bottom opening of the through hole 40 is retracted inwards, so that the caliber of the bottom opening is smaller than the diameter of the steel ball 41.
The inner wall surface of the positioning sleeve 42 is provided with a convex rib 421, and the inner wall surface of the convex rib 421 positions the steel ball 41 in the through hole. The outer end surface of the rib 421 is a slope structure, and the inner end surface is perpendicular to the inner wall surface of the positioning sleeve 42.
The outer wall of the connecting seat 4 is sleeved with a spring 43, and the inner end surface of the convex rib 421 is abutted against the spring 43. The outer wall of the connecting seat 4 is provided with a limiting table 44, and the positioning sleeve 42 slides towards the limiting table 44, so that the convex rib 421 is separated from the steel ball 41, and the convex rib 421 pushes the spring 43 against the limiting table 44 and compresses the spring.
When the positioning sleeve 42 is loosened, the steel ball can be smoothly pressed into the through hole again because the outer end surface of the convex rib 421 is of a slope structure.
In order to prevent the steel balls from sliding out of the through holes after the positioning sleeve 42 is slid toward the limiting table 44, a limiting sleeve 45 is provided on the outer wall of the connecting seat 4, and the limiting sleeve 45 is fixed on the connecting seat 4 through a spring clip 46. The limiting sleeve 45 is positioned in the positioning sleeve 42 and is arranged outside the steel ball 41.
When the positioning sleeve 42 is used, the position of the positioning sleeve 42 is moved, the outer end face of the positioning sleeve 42 is flush with the inner end face of the limiting sleeve 45, the convex rib 421 is just completely separated from the steel ball 41, and if the steel ball needs to be taken down, the position of the positioning sleeve 42 is continuously moved, and the steel ball is completely exposed.
In order to better insert the connector 3 into the connecting seat 4, the end of the connector 3 is a tapered head structure. The groove surface of the locking groove 31 on the connector 3 is an arc surface, and the arc surface enables the steel ball to better enter or separate from the groove.
When the connector 3 is inserted into the connecting seat 4, the rib 421 is located at the position of the steel ball, the steel ball is limited in the locking groove 31 of the connector 3, and the connector 3 and the connecting seat 4 cannot fall off. The positioning sleeve 42 is moved to separate the rib 421 from the steel ball, when the connector is pulled, the locking groove 31 lifts the steel ball, and the connector and the connecting seat can be separated.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the utility model and these modifications should also be considered as the protection scope of the utility model.
