Abstract
The utility model provides a self-locking quick-changing connector, which comprises a female connector, a male connector and a valve body. A locking sleeve and a sleeve ring are sequentially sleeved on the female connector, the locking sleeve is in a cylinder shape, a retaining position is arranged on the outer wall of the locking sleeve, grooves which are respectively axial grooves and circumferential grooves are arranged on the inner wall of the locking sleeve, the circumferential grooves are arranged on the rear section of the locking sleeve and communicated with the axial grooves, positioning blocks are arranged between the locking sleeve and the female connector, the lower portions of the positioning blocks are arranged in the female connector, the upper portions of the positioning blocks are arranged in the grooves of the locking sleeve, and the locking sleeve can slide and rotate on the female connector along the axial grooves and the circumferential grooves. The self-locking quick-changing connector can lock the sleeve ring and prevent the sleeve ring from moving backwards, so that the quick-changing connector can be prevented from releasing by mistake, and further is firm in connection and stable in working.
Description
Technical field
The utility model relates to a kind of quick release coupling, be specially a kind of tight device with lock can anticreep quick release coupling, be mainly used in vibrations and the pipe-line system of impacting in.
Background technique
Heavy-duty car and the used quick release coupling of farm machinery do not need tool using or special arrangement can connect or break off its hydraulic plumbing system fast at present, thereby realize the transmission of hydraulic power.Existing quick release coupling in the course of the work; Just rely on the spring force effect and compress lasso and steel ball locks, agricultural machinery is in the farming operation process, because of agricultural crop straw, weeds etc. is prone to be wrapped on the quick release coupling; Receive external force effect or vibrations, quick release coupling is prone to produce mistake and throws off; The hydraulic power that heavy-duty car need transmit is very big, and is accompanied by vibrations and impact often, so also unstable in its hydraulic plumbing system work, and quick release coupling is prone to produce the mistake disengagement, and causes the hydraulic machinery cisco unity malfunction.
Summary of the invention
The utility model provides a kind of self-locking quick release coupling, has solved quick release coupling used in existing heavy-duty car and the farm machinery and has been prone to produce the shortcoming that mistake is thrown off.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of self-locking quick release coupling comprises negative joint, male connector and valve body at least, is socketed with lock sleeve and lasso on the negative joint successively; Lock sleeve is cylindric, and its outer wall is provided with the backstop position, and the inwall of lock sleeve is provided with groove; Set groove is respectively axial groove and circumferential groove; Circumferential groove is positioned at the back segment of lock sleeve and is communicated with axial groove, is provided with positioning block between lock sleeve and the negative joint, and the bottom of positioning block is positioned at the negative joint body; The top of positioning block is positioned at the groove of lock sleeve, and lock sleeve can slide on negative joint and rotates along axial groove and circumferential groove.
Positioning block adopts locking ball.Axial groove and circumferential groove on the lock sleeve are half slot.Lock sleeve is step-like cylinder, and its leading portion external diameter is less than the back segment external diameter, and the leading portion of lock sleeve is positioned at the inside of lasso.
The self-locking quick release coupling that the utility model provides has following advantage: when negative joint with after male connector is connected, lock sleeve is pushed ahead along the direction of axial groove, be positioned at circumferential groove until locking ball; Rotate to an angle lock sleeve this moment, and locking ball and axial groove be not just on same straight line, and lock sleeve is deactuate and being stuck on the lasso backward; Stop lasso to move backward; Thereby avoided the mistake of quick release coupling to throw off, and then made this quick release coupling be connected firmly working stability.
Description of drawings
The structural representation of the self-locking quick release coupling that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation of lock sleeve;
Among the figure, 1-male connector, 2-lasso, 3-steel ball, 4-spring, 5-lock sleeve, 6-locking ball, 7-valve body, 8-negative joint, 9-circumferential groove, 10-axial groove.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The structure of the self-locking quick release coupling that the utility model provides is as shown in Figure 1, is made up of male connector 1, negative joint 8 and valve body 7, and valve body 7 comprises negative joint valve body and male connector valve body, lays respectively at the inside of negative joint 8 and male connector 1.Be socketed with lock sleeve 5 and lasso 2 on the negative joint 8 successively, be provided with spring 4 and steel ball 3 between lasso 2 and the negative joint 8, be used for realizing being connected and disconnection and positioning and locking of negative joint and male connector.
The structure of lock sleeve is as shown in Figure 2, and lock sleeve 5 is cylindric, and its outer wall is provided with the backstop position, and in the present embodiment, lock sleeve 5 is step-like cylinder, and its leading portion external diameter is less than the back segment external diameter, and the leading portion of lock sleeve 5 is positioned at the inside of lasso 2.The inwall of lock sleeve 5 is provided with groove, is respectively axial groove 10 and circumferential groove 9, and axial groove 10 is half slot with circumferential groove 9; Circumferential groove 9 is positioned at the back segment of lock sleeve 5 and is communicated with axial groove 10; Be provided with positioning block between lock sleeve 5 and the negative joint 8, the bottom of positioning block is positioned at negative joint 8, and the top of positioning block is positioned at the groove of lock sleeve; In the present embodiment, positioning block adopts locking ball 6.Lock sleeve 5 can slide on negative joint 8 and rotates along axial groove 10 and circumferential groove 9.
The working principle of the self-locking quick release coupling that the utility model provides is following: when negative joint with after male connector is connected; Lock sleeve is pushed ahead along the direction of axial groove; Be positioned at circumferential groove until locking ball, rotate to an angle lock sleeve this moment along circumferential groove, and locking ball and axial groove be not just on same straight line; Lock sleeve is deactuate and being stuck on the lasso backward; Stop lasso to move backward, quick release coupling has guaranteed the quick release coupling working stability receiving not produce the mistake disengagement under external force effect or the vibrations.When needs broke off quick release coupling, the rotational lock cover made locking ball be positioned at the position that circumferential groove is connected with axial groove, and locking ball and axial groove are located along the same line; This moment, lock sleeve can be along the axial groove pulled backwards; Thereby remove the locking to lasso, lasso is deactuate backward, the pulling lasso; Male connector just can be deviate from negative joint, breaks off hydraulic plumbing system.
