Description

Technical Field

[0001] The utility model belongs to mechanical connection technology and relates to a quick connection joint with a locking function. Background Art

[0002] A connection part of a push-pull linkage mechanism is required to have a quick connection function, and it is also required to be easy to sense whether the connection is in place, so that it is easy to blindly disassemble and install in a limited space, and the connection is reliable and not easy to loosen under vibration and other environments. When using a conventional quick-connect connector, it is necessary to overcome the large anti-backlash spring pressure during connection. At the same time, in order to ensure a reliable connection, an additional locking structure is required to lock it after connection to prevent it from loosening.

[0003] However, the disadvantages of the prior art are: 1. It is necessary to overcome a large anti-backlash spring pressure during installation, which is laborious; 2. The human perception ability is weak; 3. There is no locking mechanism, and an additional locking structure is required for locking. Utility Model Content

[0004] The purpose of the utility model is to propose a quick connection connector with a locking function, which can be easily disassembled and assembled by hands without the use of tools in a limited space, and can sense whether the connection is in place, saving time and effort, and is not easy to loosen in an environment such as vibration.

[0005] The technical solution of the utility model is: a quick-connect connector with a locking function, characterized in that it includes an upper connecting rod 1, an anti-backlash spring 2, a push rod 3, a support sleeve 4, a locking pin 5, a sliding sleeve 6, a return spring 7, a steel ball 8, a locking slide groove 9, and a lower connecting rod 10, wherein:

[0006] The upper end of the upper connecting rod 1 is a rod-shaped structure, and a cavity is arranged at the lower end; the push rod 3 is arranged at the lower end of the upper connecting rod 1, and a clearance-eliminating spring 2 is arranged in the cavity between the push rod 3 and the upper connecting rod 1; a lower connecting rod 10 is arranged at the lower end of the push rod 3; a return spring 7 is arranged between the support sleeve 4 and the sliding sleeve 6, a locking groove 9 is arranged on the support sleeve 4, and N locking pins 5 are installed on the sliding sleeve 6. The locking groove 9 and the locking pin 5 cooperate to form a locking mechanism, thereby realizing the locking function of the quick connection joint; a steel ball retaining hole is arranged at the lower end of the support sleeve 4, and a steel ball 8 is placed and installed in the steel ball retaining hole.

[0007] Specifically, the locking groove 9 is a spiral structure.

[0008] Specifically, the locking slide groove 9 is provided with a soft locking groove at the open position and the locking position of the quick connect connector.

[0009] Specifically, when disassembling or assembling, the sliding sleeve 6 is rotated left or right, and the locking pin 5 slides in the locking sliding groove 9, driving the sliding sleeve 6 to move up and down, thereby realizing the opening or locking of the quick connection joint.

[0010] Specifically, the return spring 7 is used to keep the sliding sleeve 6 in the open position or the locked position of the quick-connect connector, so that it is not easy to loosen under vibration or other conditions.

[0011] Specifically, N is 3.

[0012] The advantages of the utility model are as follows: the quick connection joint integrates a locking mechanism, which saves an additional locking mechanism; the quick connection joint can be disconnected and connected by rotating the sliding sleeve 6 to the left or right, and a locking function is realized at the connection position, and it is not easy to loosen under vibration and other environments, and at the same time provides obvious artificial perception ability, and the disassembly and assembly are convenient and reliable, saving trouble and labor.

[0013] The locking structure is designed to provide obvious locking perception, which is convenient for human perception. When disassembling or assembling, the sliding sleeve 6 is rotated to the left or right, and the locking pin 5 slides in the locking slide groove 9, driving the sliding sleeve 6 to move up and down, so as to realize the opening or locking of the quick connection joint. The locking slide groove 9 is provided with a soft positioning groove at the opening position and the locking position of the quick connection joint. The sliding sleeve 6 can be kept in the opening position or the locking position of the quick connection joint through the action of the return spring 7, and provides obvious locking perception, which is convenient for human perception, and is not easy to loosen under vibration and other environments.

[0014] Since the locking mechanism adopts a spiral structure, the pressure of the anti-backlash spring is decomposed during connection, reducing the influence of the pressure of the anti-backlash spring on installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below.

[0021] See also Figure 1 , Figure 2 , Figure 3 The utility model proposes a quick-connect joint with a locking function, comprising an upper connecting rod 1, an anti-backlash spring 2, a push rod 3, a support sleeve 4, a locking pin 5, a sliding sleeve 6, a return spring 7, a steel ball 8, a locking slide groove 9, and a lower connecting rod 10, wherein:

[0022] The upper end of the upper connecting rod 1 is a rod-shaped structure, and a cavity is arranged at the lower end; the push rod 3 is arranged at the lower end of the upper connecting rod 1, and a clearance-eliminating spring 2 is arranged in the cavity between the push rod 3 and the upper connecting rod 1; a lower connecting rod 10 is arranged at the lower end of the push rod 3; a return spring 7 is arranged between the support sleeve 4 and the sliding sleeve 6, a locking groove 9 is arranged on the support sleeve 4, and N locking pins 5 are installed on the sliding sleeve 6. The locking groove 9 and the locking pin 5 cooperate to form a locking mechanism, thereby realizing the locking function of the quick connection joint; a steel ball retaining hole is arranged at the lower end of the support sleeve 4, and a steel ball 8 is placed and installed in the steel ball retaining hole.

[0023] Specifically, the locking groove 9 is a spiral structure.

[0024] Specifically, the locking slide groove 9 is provided with a soft locking groove at the open position and the locking position of the quick connect connector.

[0025] Specifically, during disassembly and assembly, the sliding sleeve 6 is rotated left or right, and the locking pin 5 slides in the locking sliding groove 9, driving the sliding sleeve 6 to move up and down, thereby realizing the opening or locking of the quick connection joint, and decomposing the pressure of the anti-backlash spring during connection, reducing the influence of the pressure of the anti-backlash spring on the installation.

[0026] Specifically, the return spring 7 is used to keep the sliding sleeve 6 in the open position or the locked position of the quick-connect connector, so that it is not easy to loosen under vibration or other conditions.

When there is no integrated locking mechanism, the sliding sleeve 6 needs to be pushed up and pulled down to realize the disengagement and connection of the quick connection joint.

[0029] It should be noted that due to the structural design of the rotating groove on the support sleeve, when in the locked position, the connection will not be disconnected due to environmental influences such as vibration, thereby ensuring a reliable connection.
