Detailed ways

The technical solution of the present utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

In the following definitions of front and rear directions, the front and rear directions of the FIX connector 100 are defined in use, where the end of the FIX connector 100 used to lock and connect to other components is the front end, and the opposite direction is the rear. The ground is the left-right direction in Figures 1 and 2, where the right is the front and the left is the rear.

Referring to the FIX connector 100 shown in Fig. 1 and Fig. 2 and the secondary unlocking mechanism 200 provided thereon, the FIX connector 100 includes a housing 10, and a connection which is provided at the front of the housing 10 for locked connection with other components. The locking structure (not shown in the figure), and the pull rod (not shown in the figure) which is provided in the housing 10 to move forward and backward for unlocking the above-mentioned connecting locking structure.

1 to 9, the secondary unlocking mechanism 200 is arranged outside the housing 10 for controlling the unlocking of the FIX connector 100. The secondary unlocking mechanism 200 includes an unlocking button 2 arranged outside the housing 10. The unlocking button 2 is connected with the pull rod through the pin shaft 7, by pushing the unlock button 2 to move backward, the pull rod can be pulled to move backward to unlock the connection locking mechanism of the FIX connector 100, and when the unlock button 2 moves forward, the pull rod moves toward The front reset can make the connection locking mechanism lock again.

In order to prevent false unlocking of the FIX connector 100 caused by misoperation of the unlocking button 2, the secondary unlocking mechanism 200 also includes a fixed seat 1 fixed on the housing 10, and is pivotally connected to the rear of the fixed seat 1 through a rotating shaft 6. Unlock wrench 3. The rear part of the unlocking button 2 is slidably inserted in the front part of the fixing base 1 along the front-rear direction. A first elastic member 4 is provided between the rear part of the unlock button 2 and the fixed seat 1, and the first elastic member 4 is used to provide the elastic restoring force required for the unlock button 2 to slide relative to the fixed seat 1 in the front and rear direction. One elastic member 4 adopts a spring. When the connection locking mechanism on the FIX connector 100 is in the locked state, the first elastic member 4 exerts a forward force on the unlock button 2, so that the FIX connector 100 remains locked. state.

Referring to the drawings, the unlocking wrench 3 has a locking end 31 and an operating end 32 , and the locking end 31 and the operating end 32 are respectively located on two sides of the rotating shaft 6 .

The unlocking button 2 has a blocking portion 21 for cooperating with the locking end 31. When the secondary unlocking mechanism 200 is in the locked state, the locking end 31 of the unlocking wrench 3 is located behind the blocking portion 21 to prevent the unlocking button 2 from sliding backward. , so that the FIX connector 100 cannot be unlocked; when the unlocking wrench 3 rotates around the rotating shaft 6, the locking end 31 rotates away from the blocking portion 21, and the rear of the blocking portion 21 loses the barrier, so that the unlocking button 2 can be moved backward relative to the fixed seat 1 At this time, press the unlocking button 2 backward to move backward against the elastic force of the first elastic member 4 to unlock the FIX connector 100 .

Referring to the accompanying drawings, the blocking portion 21 is a rib located on one side of the unlocking button 2, and the ribs are distributed along the front and rear directions. It is slidably inserted into the slide groove 11 along the front-rear direction to provide a slide guide for the unlock button 2 .

A second elastic member 5 is provided between the unlocking wrench 3 and the fixing seat 1 , and the second elastic member 5 is used to provide the elastic restoring force required for the unlocking wrench 3 to rotate around the rotation axis 6 relative to the fixing seat 1 . The second elastic member 5 is also a spring, and the spring is arranged between the operating end 32 and the fixing seat 1 . Under normal conditions, the second elastic member 5 exerts an elastic restoring force on the operating end 32 to rotate around the rotating shaft 6, so that the operating end 32 has a tendency to rotate upwards, so that the locking end 31 is fixedly blocked behind the blocking portion 21, Therefore, the unlock button 2 is prevented from sliding backward to unlock the FIX connector 100 .

As shown in FIGS. 2 to 9 , a locking slot 12 is provided at the rear of the fixing base 1 , and a limiting protrusion 33 is provided on the operating end 32 to rotatably snap into the aforementioned locking slot 12 . When the secondary unlocking mechanism 200 is locked, the limiting protrusion 33 is correspondingly snapped into the slot 12 , so that the secondary unlocking mechanism 200 is stably in the locked state.

Referring to Fig. 2, Fig. 6 and Fig. 7, when the FIX connector 100 is in the locked state, the secondary unlocking mechanism 200 is also in the locked state. Between, the second elastic member 5 resists between the operating end 32 of the unlocking wrench 3 and the fixed seat 1, and the locking end 31 is located behind the blocking portion 21 on the unlocking button 2. When the unlocking button 2 is pressed backward, the blocking portion 21 is blocked by the front of the locking end 31 so that the unlocking button 2 cannot continue to slide backwards, thus ensuring that the unlocking button 2 cannot slide backwards to unlock the FIX connector, so that the FIX connector 100 is stably in the locked state;

When it is necessary to unlock the FIX connector 100, as shown in FIG. 7, firstly, the user rotates the operating end 32, so that the locking end 31 rotates away from the rear of the blocking portion 21, so that the rear of the blocking portion 21 loses the barrier, as shown in FIG. 8, at this time, press the unlock button 2 backwards, so that the unlock button 2 overcomes the elastic force of the first elastic member 4, and then slides backward relative to the fixed seat 1, and then pulls the pull rod in the FIX connector 100 backward. Slide to unlock the FIX connector 100 , as shown in FIG. 9 . The above-mentioned secondary unlocking mechanism 200 has a simple structure, reliable locking, and convenient operation, which improves the connection safety of the FIX connector 100 .

In some embodiments, the blocking portion 21 is also a protrusion provided on one side of the unlock button 2, and the protrusion can be slidably inserted into the slide groove 11 on the fixing seat 1 in the front and rear direction to provide the ability for the unlock button 2 to slide back and forth. Guiding, a pin hole can be opened on the convex part to install the pin shaft and then connect with the connector 100 .

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to enable those familiar with this technology to understand the content of the present utility model and implement it accordingly, and not to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
