[0029] See also Figure 1-4 The utility model provides a technical solution: a quick connector with waist-shaped hole steel ball locking to achieve one-hand operation, comprising a female end main shaft sleeve 1 and a male end main shaft sleeve 2;

[0030] The outer wall of one end of the female end main shaft sleeve 1 is sleeved with a female end shaft end sleeve 11, the inner cavity of the female end main shaft sleeve 1 is provided with a female end valve core 12, one end of the female end valve core 12 is fixedly connected to the inner wall of the female end shaft end sleeve 11, the other end of the female end valve core 12 is sleeved with a valve core shaft sleeve 15, the outer wall of the female end valve core 12 is sleeved with an adaptive female end spring 14, the other end of the female end main shaft sleeve 1 is sleeved with a steel ball locking sleeve 13, the outer wall of the female end main shaft sleeve 1 is sleeved with a female end locking spring 16, the two ends of the female end locking spring 16 are respectively pressed against one end of the female end shaft end sleeve 11 and the inner wall of the steel ball locking sleeve 13, one end of the female end main shaft sleeve 1 is alternately provided with a plurality of evenly distributed waist-shaped holes 19 and straight holes 3, and adaptive steel balls 17 are arranged in the waist-shaped holes 19 and the straight holes 3;

[0031] A male end shaped part 21 is installed at one end of the inner cavity of the male end main shaft sleeve 2, and a terminal head is arranged at the other end of the inner cavity of the male end main shaft sleeve 2. A male end spring 22 is installed between the terminal head and the male end shaped part 21. The outer wall convex part of the male end main shaft sleeve 2 is provided with a first inclined surface 26, a plane 27 and a second inclined surface 28.

[0032] In actual use, in the unconnected state, the steel ball 17 in the waist-shaped hole 19 is pressed against the rightmost side of the waist-shaped hole 19 by the second inclined surface 28 under the action of the female end locking spring 16; when the first inclined surface 26 of the male end main shaft sleeve 2 contacts the steel ball 17, as shown in FIG. Figure 4 As shown, the steel ball 17 rolls in the waist-shaped hole 19 along direction 1; when it reaches the leftmost side of the waist-shaped hole 19, the steel ball will no longer roll along direction 1, but along Figure 4 The plug and socket continue to dock. When the first inclined surface 26 of the male end main shaft sleeve begins to contact the steel ball 17 in the straight hole 3, the steel ball 17 begins to roll and begins to contact the second inclined surface 28 of the steel ball locking sleeve 13. It rolls along this inclined surface to make room for the plane 27 of the male end main shaft sleeve 2, and then rolls along the second inclined surface 28. When rolling to the second inclined surface 28, it reaches a self-locking state. In the self-locking state, the steel ball 17 is on the second inclined surface 28, as shown in FIG. Figure 2 As shown, the steel ball 17 corresponding to the waist-shaped hole 19 is on the rightmost side of the waist-shaped hole 19. Figure 5 shown.

[0033] The disconnection process is the same. First, the steel ball 17 in the straight hole 3 rolls in the opposite direction along the trajectory, that is, it first rolls along the second inclined surface 28, then reaches the plane 27, and then rolls along the first inclined surface 26; this process will drive the steel ball 17 in the waist-shaped hole 19 to roll in the opposite direction along the trajectory. When the steel ball 17 in the waist-shaped hole 19 breaks away from the first inclined surface 26 on the male end main shaft sleeve 2, the plug and socket are disconnected.

[0034] Furthermore, a first annular groove is provided at the inner corner of the female shaft end sleeve 11 and a first rubber ring 4 is embedded in the first annular groove. The provision of the first rubber ring 4 ensures a good sealing effect between the female shaft end sleeve 11 and the female main shaft sleeve 1.

[0035] Furthermore, a second annular groove is provided on the outer wall of the female valve core 12 corresponding to the valve core sleeve 15, and a third annular groove is provided on the inner wall of the female main shaft sleeve 1 corresponding to the valve core sleeve 15. Second rubber rings 18 are embedded in the second annular groove and the third annular groove. The setting of the second rubber ring 18 can improve the sealing effect between the valve core sleeve 15, the female valve core 12 and the female main shaft sleeve 1.

[0036] It is worth mentioning that a fourth annular groove is formed on the outer wall of the male end special-shaped part 21 , and a third rubber ring 25 is embedded in the fourth annular groove. The provision of the third rubber ring 25 can ensure the sealing effect between the male end special-shaped part 21 and the male end main shaft sleeve 2 .

[0037] It should be noted that the end head and the male end main shaft sleeve 2 are clamped together by a male end clamping ring 23 .

[0038] In addition, a fourth rubber ring 24 is sleeved on the outer wall of one end of the male main shaft sleeve 2. The fourth rubber ring 24 is provided to ensure a sealing effect when an external component is connected.

[0039] The implementation principle of the quick connector of the waist-shaped hole steel ball locking to realize one-hand operation is as follows: in actual use, when not docked, the steel ball 17 in the waist-shaped hole 19 is pressed against the rightmost side of the waist-shaped hole 19 by the second inclined surface 28 under the action of the female end locking spring 16; when the first inclined surface 26 of the male end main shaft sleeve 2 contacts the steel ball 17, as shown in FIG. Figure 4 As shown, the steel ball 17 rolls in the waist-shaped hole 19 along direction 1; when it reaches the leftmost side of the waist-shaped hole 19, the steel ball will no longer roll along direction 1, but along Figure 4 The plug and socket continue to dock. When the first inclined surface 26 of the male end main shaft sleeve begins to contact the steel ball 17 in the straight hole 3, the steel ball 17 begins to roll and begins to contact the second inclined surface 28 of the steel ball locking sleeve 13. It rolls along this inclined surface to make room for the plane 27 of the male end main shaft sleeve 2, and then rolls along the second inclined surface 28. When rolling to the second inclined surface 28, it reaches a self-locking state. In the self-locking state, the steel ball 17 is on the second inclined surface 28, as shown in FIG. Figure 2 As shown, the steel ball 17 corresponding to the waist-shaped hole 19 is on the rightmost side of the waist-shaped hole 19. Figure 5 shown.

[0040] The disconnection process is the same. First, the steel ball 17 in the straight hole 3 rolls in the opposite direction along the trajectory, that is, it first rolls along the second inclined surface 28, then reaches the plane 27, and then rolls along the first inclined surface 26; this process will drive the steel ball 17 in the waist-shaped hole 19 to roll in the opposite direction along the trajectory. When the steel ball 17 in the waist-shaped hole 19 breaks away from the first inclined surface 26 on the male end main shaft sleeve 2, the plug and socket are disconnected.

[0041] In addition, the utility model is a waist-shaped hole steel ball locking quick connector that can be operated with one hand, and the components included are all universal standard parts or components known to technical personnel in this field. The structure and principle can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible monitoring computers and power supplies, are connected through wires. The specific connection means should refer to the following working principle. The electrical connection is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.
