Abstract
Description
Technical Field
[0001] The present application relates to the technical field of empty container detection, and more specifically, to a self-locking mechanism and an empty container detection pendulum mechanism. Background Art
[0002] When container trucks enter or leave the port, they need to be inspected in real time according to the needs. The current container inspection is manual inspection, which requires a lot of human resources for inspection. Because the standardization of inbound and outbound vehicles and the inspection of empty and full containers are different, manual inspection is inevitably insufficient. In addition, the need to open and close the container door for inspection has caused the problem of slow customs clearance, especially in harsh environments. The labor intensity of the staff is high, and there are also unsafe factors when getting on and off the vehicle frequently.
[0003] Based on this, the existing container empty box detection equipment is used to automatically check whether the passing container is empty. The container empty box detection equipment is provided with a pendulum that can perform a single pendulum motion and a pendulum arranged on the pendulum. When the pendulum moves, it can drive the pendulum to move to knock the container. The sound wave signal generated after the knocking is subsequently collected, and the container is analyzed whether it is empty according to the sound wave signal. In this process, the movement of the pendulum can generally be controlled by a motor. When the pendulum is needed, the motor drives the pendulum to swing out. After the knock, the motor drives the pendulum to swing back to retract the pendulum. After the retraction, if the pendulum and the pendulum need to be maintained in a retracted state so that the pendulum does not swing out at will, the motor needs to be in a working state to maintain the retracted state of the pendulum. In this way, it is inevitable that the motor may be consumed when the pendulum is not driven to move; and when the power is suddenly cut off, the pendulum cannot normally maintain the retracted state, and it will swing out due to the gravity of the pendulum due to the power cut. Summary of the invention
[0004] In view of the prior art, the technical problem solved by the present application is to provide a self-locking mechanism and an empty box detection pendulum mechanism that can save electric energy or realize self-locking of the pendulum rod when the power is off.
[0005] In order to solve the above technical problems, in a first aspect, the present application provides a self-locking mechanism, comprising:

[0009] A clamping jaw, comprising a first jaw and a second jaw which are hinged to each other and are both hinged to the slider, the first jaw and the second jaw forming a clamping area, and the slider drives the first jaw and the second jaw to move when sliding so as to open and close the clamping area; and,
[0010] A locking rod is fixed on the slider and extends along the sliding direction of the slider, and a portion of the locking rod is stacked with the clamping area.
[0011] In one embodiment of the application, the self-locking mechanism also includes a connecting rod mechanism for realizing the hinge connection between the clamping claw and the slider, and the connecting rod mechanism includes a first connecting rod and a second connecting rod; one end of the first connecting rod and one end of the second connecting rod are hinged by a clamping fork and the hinge is hinged to the slider, and the other end of the first connecting rod and the other end of the second connecting rod are hinged to the first claw and the second claw respectively.
[0012] In one embodiment of the application, the hinge point of the first connecting rod and the second connecting rod, the hinge point of the first connecting rod and the first claw, the hinge point of the second connecting rod and the second claw, and the hinge point of the first claw and the second claw form a prism.
[0013] In one embodiment of the application, the guide groove includes two symmetrically distributed hook-shaped grooves, and the ends of the two configuration grooves are connected to form the upper self-locking position and the lower self-locking position in an inverted V shape.
[0014] In one embodiment of the application, the self-locking mechanism further includes an elastic member, one end of which is connected to the slider and the other end of which is connected to the fixing seat.
[0015] In a second aspect, the present application provides an empty box detection pendulum mechanism, which includes:
[0016] A pendulum rod, on which a pendulum for striking the container is disposed;
[0017] a driving assembly connected to the pendulum and used to drive the pendulum arm to swing out so that the pendulum strikes the container or to drive the pendulum arm to swing back so as to drive the pendulum to retract; and

[0019] The self-locking mechanism and empty box detection pendulum mechanism provided by the present application have the following beneficial effects: when the swing-back pendulum rod enters the clamping area and touches the locking rod, it drives the slider to move upward, so that one end of the swing hook set on the fixed seat slides along the guide groove to the lower self-locking position, and the slider drives the first claw and the second claw to move during the upward movement so that the clamping area continues to decrease. When the swing hook holds the lower self-locking position, the first claw and the second claw cooperate to clamp the pendulum rod. The self-locking mechanism can realize the self-locking of the pendulum rod. After that, the motor that maintains the state of the pendulum rod does not provide a maintaining force or is suddenly powered off. The pendulum rod is clamped by the self-locking mechanism and will not swing at will, which can reduce power consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The self-locking mechanism and the pendulum mechanism for empty box detection of the present application are now described in detail with reference to the accompanying drawings.
[0031] Please refer to Figures 1 to 3 The empty container detection pendulum mechanism 400 provided in the embodiment of the present application detects whether a container is empty by knocking. The empty container detection pendulum mechanism 400 includes a swing rod 200, a driving assembly 300 and a self-locking mechanism 100.
[0032] Specifically, the swing rod 200 is provided with a pendulum 201 for striking the container, and the driving assembly 300 is connected to the swing rod 200 and is used to drive the swing rod 200 to swing so as to drive the pendulum 201 to swing. Specifically, the driving assembly 300 drives the swing rod 200 to swing out in a single pendulum motion to drive the pendulum 201 on the swing rod 200 to move toward the container, so that the pendulum 201 strikes the container to generate a sound wave signal, and the generated sound wave signal can be collected later to analyze whether the container is empty or not empty; after striking the container, the driving assembly 300 is used to drive the swing rod 200 to swing back in a single pendulum motion. When the self-locking mechanism 100 is arranged on one side of the swing rod 200, the self-locking mechanism 100 is used to hold the swing rod 200 that is swinging back.
[0033] As 1 and Figure 2As shown, the driving assembly 300 includes a motor 301, a driving wheel 302, a driven wheel 303 and a synchronous belt 304 for connecting the driving wheel and the driven wheel 303. The rocker arm 200 and the driven wheel 303 are coaxially connected. The motor 301 is connected to the driving wheel 302 and is used to drive the rocker arm 200 to rotate. The driven wheel 303 is rotated by the action of the synchronous belt 304, and the rotating driven wheel 303 drives the rocker arm 200 to swing.
[0034] Refer to Figure 4 and Figure 5 The self-locking mechanism 100 includes a fixed seat 10, a slider 20, a swing hook 30, a clamping claw 40 and a locking rod 50. Specifically, the slider 20 can slide on the fixed seat 10, one end of the swing hook 30 is set on the fixed seat 10, and a guide groove 21 is provided on the slider 20 for the other end of the swing hook 30 to slide during its sliding process. The two ends of the guide groove 21 are respectively provided with an upper self-locking position 211 and a lower self-locking position 212 for the other end of the swing hook 30 to hook. The clamping claw 40 includes a first claw 41 and a second claw 42 that are mutually forked and hinged and are both hinged on the slider 20. The first claw 41 and the second claw 42 form a clamping area 43. When the slider 20 slides, the first claw 41 and the second claw 42 are driven to move so that the clamping area 43 is opened and closed. In addition, the locking rod 50 is fixedly arranged on the slider 20 and extends along the sliding direction of the slider 20. Part of the locking rod 50 is arranged in a stacked manner with the clamping area 43.
[0035] Furthermore, the first claw 41 and the second claw 42 are cross-hinged in the middle, one end of the first claw 41 and one end of the second claw 42 are partially hinged on the slider 20, and during the hinged movement of the first claw 41 and the second claw 42, the other end of the first claw 41 and the other end of the second claw 42 form an openable and closable clamping area 43. The openable and closable opening of the clamping area 43 is arranged toward the swing rod 200, and the swing rod 200 can enter and exit the clamping area 43 during the swinging process, and the self-locking mechanism 100 is used for the clamping jaw 40 to clamp the swing rod 200 when the swing rod 200 swings back.
[0036] like Figure 4 and Figure 5 As shown, the self-locking mechanism 100 also includes a connecting rod mechanism 60 for realizing the hinge connection between the clamping claw 40 and the slider 20. The connecting rod mechanism 60 includes a first connecting rod 61 and a second connecting rod 62; one end of the first connecting rod 61 and one end of the second connecting rod 62 are hinged with a clamping fork and the hinge is hinged to the slider 20, and the other end of the first connecting rod 61 and the other end of the second connecting rod 62 are hinged to the first claw 41 and the second claw 42 respectively. It can be understood that when the first connecting rod 61 and the second connecting rod 62 follow the sliding process of the slider 20, they will drive the first claw 41 and the second claw 42 hinged with the clamping fork to perform a scissor-like opening and closing movement.
[0037] It is worth noting that, referring to Figures 3 to 5, the locking process of the self-locking mechanism 100 during use: when the clamping claw 40 is in a state of not clamping the swing rod 200, the two ends of the first claw 41 and the second claw forming the clamping area 43 are in the most distant state, and at this time, the end of the swing hook 30 that slides in the guide groove 21 is hooked in the upper self-locking position 211. After the swing rod 200 drives the pendulum 201 to knock on the container, the swing rod 200 drives the pendulum 201 to swing back and enter the clamping area 43 formed by the first claw 41 and the second claw 42, the swing rod 200 will touch the locking rod 50 stacked in front and behind the clamping area 43, and the swing rod 200 will continue to touch the swing rod 200 during the swinging and retracting movement, prompting the slider 20 to move upward. During the upward movement of the slider 20, the first connecting rod 61 and the second connecting rod 62 hinged on the slider 20 are driven to move, so that the first claw 41 and the second claw 42 clamp fork move, which will gradually reduce the clamping area 43. When the slider 20 moves, the swing hook During the process of one end of the slide 20 moving in the guide groove 21 from the upper self-locking position 211 to the lower self-locking position 212, since the force of the motor 301 driving the swing rod 200 to swing is constant, the swing rod 200 generally cannot swing all the time. When the swing rod 200 stops swinging, the swing rod 200 can no longer touch the locking rod 50, and the slider 20 will lose the driving force to move upward. When the swing hook 30 is hooked to the lower self-locking position 212, the slider 20 stops moving. At this time, the first claw 41 and the second claw 42 form a clamping area 43 to clamp the swing rod 200. At this time, the motor 301 provides a maintaining force or a sudden power failure, which can also ensure that the swing rod 200 does not swing out at will. Among them, the slider 20 slides downward as shown in FIG. Figure 3 As shown, the slider 20 slides upward as shown in Figure 5 shown.
[0038] It is worth noting that, referring to Figures 3 to 5 , the unlocking process of the self-locking mechanism 100 during use: when the swing rod 200 is needed to drive the pendulum 201 to swing out to knock on the container, the motor 301 can first give the swing rod 200 a driving force, so that the swing rod 200 touches the locking rod 50, and the slider 20 will slide upward first, so that the swing hook 30 is no longer hooked on the lower self-locking position 212, and then the slider 20 slides down due to the gravity of the clamping claw 40 and the connecting rod mechanism 60, and then the swing hook 30 moves along the guide groove 21, and the movement of the connecting rod mechanism 60 and the clamping claw 40 is opposite to the locking process of the self-locking mechanism 100, and finally the end of the swing hook 30 sliding in the guide groove 21 will move to the upper self-locking position 211, and the hook holds the upper self-locking position 211 without moving. In this process, the area of the clamping area 43 is first enlarged, and finally the swing rod 200 is unlocked and released.
[0039] In an embodiment of the application, the hinge points of the first connecting rod 61 and the second connecting rod 62, the hinge points of the first connecting rod 61 and the first claw 41, the hinge points of the second connecting rod 62 and the second claw 42, and the hinge points of the first claw 41 and the second claw 42 form a prism. In this way, the prism structure is conducive to uniform force.
[0040] like Figure 4 As shown, the guide groove 21 includes two symmetrically distributed hook-shaped grooves, and the ends of the two configuration grooves are connected to form an inverted V-shaped upper self-locking position 211 and a lower self-locking position 212. The swing hook 30 slides in the guide groove 21 and one end is a bent hook, which is convenient for hooking and holding the upper self-locking position 211 and the lower self-locking position 212.
[0041] Furthermore, the self-locking mechanism 100 further includes an elastic member, one end of which is connected to the slider 20 and the other end of which is connected to the fixing seat 10 .
[0042] In the above self-locking mechanism 100, when the swing-back pendulum 200 enters the clamping area 43 and touches the locking rod 50, the slider 20 is driven to move upward, so that one end of the swing hook 30 provided on the fixed seat 10 slides along the guide groove 21 to the lower self-locking position 212, and the slider 20 drives the first claw 41 and the second claw 42 to move during the upward movement so that the clamping area 43 continues to decrease. When the swing hook 30 hooks the lower self-locking position 212, the first claw 41 and the second claw 42 cooperate to clamp the pendulum 200. The self-locking mechanism 100 can realize the self-locking of the pendulum 200. After that, the motor 301 that maintains the state of the pendulum 200 does not provide a maintaining force or is suddenly powered off. The pendulum 200 is clamped by the self-locking mechanism 100 and does not swing at will, which can reduce power consumption.
[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
