[0023] The application will be described in detail below in conjunction with the embodiments, but the application is not limited to these embodiments.

[0024] Reference Figures 1-6 A CA-3 coupler lock holder gauge, characterized in that it comprises:

[0025] The rectangular frame is surrounded by a first frame 1, a second frame 2, a third frame 3, and a fourth frame 4, and the thicknesses of the first frame 1, the second frame 2, the third frame 3, and the fourth frame 4 are different.

[0026] The first frame 1, the second frame 2, the third frame 3 and the fourth frame 4 of different thicknesses detect the coupler lock bracket in different states.

[0027] The different states of the coupler lock bracket detection include a first state, a second state, a third state and a fourth state.

[0028] The bottom of the rectangular frame abuts against the coupler tooth 5.

[0029] In the first state and the third state, the top of the first frame 1 and the third frame 3 respectively abuts against the lock bracket 6, so that the hook lock 7 partially enters the lock cavity.

[0030] In the second state and the fourth state, the top of the second frame 2 and the fourth frame 4 respectively abuts against the lock bracket 6, so that the hook lock 7 completely enters the lock cavity.

[0031] Specifically, the gauge has four detection sizes in common, and the detection of the CA-3 coupler lock bracket is completed by using the different thicknesses of the first frame, the second frame, the third frame and the fourth frame. In the first state, the function of preventing the coupler from being accidentally uncoupled is detected by using the first frame. As shown in Figure 2 、 Figure 3 , the lock bracket is clamped at the first frame of the gauge, at this time, the hook lock is pushed, and if the hook lock cannot completely enter the lock cavity, it means that it is qualified. In the second state, whether the functions of each component are normal when the coupler is in a free state is detected by using the second frame. As shown in Figure 2 、 Figure 4 , the lock bracket is clamped at the second frame of the gauge, at this time, the hook lock is pushed, and if it can completely enter the lock cavity, it means that it is qualified. In the third state, the reliability of the locking system when uncoupling is detected by using the third frame. As shown in Figure 2 、 Figure 5 , the lock bracket is clamped at the third frame of the gauge, first, the hook lock is pushed to ensure that the hook lock cannot completely enter the lock cavity, then the hook lifting wheel 10 is rotated to make the hook lock completely enter the lock cavity, and finally the hook lifting wheel 10 is released. If the hook lock can be kept at this time, and after the gauge is released, it can return to the original position under the action of gravity, and other parts can also return to the original position without obstacles, it means that it is qualified. If the hook lifting wheel 10 is released, the hook lock cannot be kept, which is unqualified. In the fourth state, whether the uncoupling device works normally is detected by using the fourth frame. As shown in Figure 2 、 Figure 6As shown, the gauge is straight edge, that is, the fourth frame at the lock to hold, at this time, the hook to rotate the wheel 10, so that the hook lock into the lock cavity, in the hook to rotate the wheel 10, the lock to not from the car hook opening wall to push the gauge, and all components can be kept in the disengaged position, and after removing the gauge, there is no obstacle to return to the initial position, which is eligible; wherein, the four state is eligible, the lock to the working state of CA-3 car coupler is eligible, can be regarded as CA-3 car coupler, the gauge is simple, convenient to carry and no requirement for the operating environment.

[0032] The second state of the lock 6 exposed to the height of the lock cavity is greater than the height of the lock 6 exposed to the lock cavity in the first state;

[0033] The first state of the lock 6 exposed to the height of the lock cavity is greater than the height of the lock 6 exposed to the lock cavity in the third state;

[0034] The third state of the lock 6 exposed to the height of the lock cavity is greater than the height of the lock 6 exposed to the lock cavity in the fourth state.

[0035] Specifically, the gauge has four detection sizes, respectively, the first frame, the second frame, the third frame and the fourth frame (the straight edge of the boss pressure head installation).

[0036] The first item is to detect the function of preventing the car coupler from being accidentally uncoupled. As shown, Figure 2 , Figure 3 The gauge is held at the first frame of the lock. At this time, push the hook lock, if the hook lock cannot completely enter the lock cavity, it is eligible. (When used in this position, note that the gauge boss should be in the lower position as shown in Figure 3 ).

[0037] The second item is to detect whether the function of each component is normal when the car coupler is in a free state. As shown, Figure 2 , Figure 4 The gauge is held at the second frame of the lock. At this time, push the hook lock, if it can completely enter the lock cavity, it is eligible. (When used in this position, note that the gauge boss should be in the upper position as shown in Figure 4 ).

[0038] The third item is to detect the reliability of the locking system when uncoupling. As shown, Figure 2 , Figure 5 The gauge is held at the third frame of the lock. First, push the hook lock to ensure that the hook lock cannot completely enter the lock cavity, then rotate the hook lifting wheel to make the hook lock completely enter the lock cavity, and then release the hook lifting wheel. If the hook lock can be kept at this time, and the gauge can return to the original position under the action of gravity after releasing the gauge, and other parts can also return to the original position without obstacles, it is eligible. If the hook lock cannot be kept after releasing the hook lifting wheel, it is not eligible.

[0039] Fourth, detect whether the unhooking device is working properly. As shown in Figure 2 , Figure 6 , the ruler straight edge, that is, the fourth frame is stuck in the lock, at this time the hook lifting wheel, so that the hook lock into the lock cavity, in the hook lifting wheel rotation, the lock is not from the car hook opening wall to push open, and all components can be in the disengaged position to maintain, and remove the ruler after, no obstacles return to the initial position, then it is eligible.

[0040] Four state eligible, CA-3 coupler lock holder working state eligible, can be considered as CA-3 coupler eligible.

[0041] The fourth frame 4 is provided with a boss head 8, the top of the boss head 8 abuts against the lock holder 6, so that the hook lock 7 is completely in the lock cavity.

[0042] Specifically, the boss head is provided for detecting the eligible condition of the coupler lock holder in the fourth state. The top of the boss head is parallel to the rectangular frame.

[0043] The rectangular frame is provided with a positioning pin 9 at each corner, the positioning distance between adjacent two positioning pins 9 is equal, and the positioning distance is the width of the lock holder 6.

[0044] Specifically, the positioning pin is provided for detecting the accuracy.

[0045] The above is only a few embodiments of the present application, not any form of the application to limit, although the preferred embodiments disclosed as above, however, not to limit the application, any skilled in the art, without departing from the scope of the technical solutions of the present application, using the above disclosed technical content to make some changes or modifications are equivalent to equivalent embodiments, all belong to the scope of the technical solutions.
