Description

Technical Field

[0001] The utility model relates to the technical field of self-locking equipment, in particular to a locking component. Background Art

[0002] Deep-sea aquaculture cages refer to aquaculture cages that can be used in relatively deep sea areas (usually the depth of the sea area is greater than 20m). They are aquaculture equipment that has developed rapidly in the past decade. They use high-tech technologies such as computers, new materials, pneumatics, corrosion resistance, anti-fouling (attachment), and anti-ultraviolet (anti-aging). Even in very harsh sea conditions, they can keep the cage structure system and the fish they culture safe and sound. However, the existing net covers on the periphery of the cages are tied to the box body by ropes. When adjusting the covering position of the net cover, it is necessary to manually adjust the length of the rope to control it, which is cumbersome to operate and inefficient. Utility Model Content

[0029] The following is combined with Figure 1-4 , the embodiments of the utility model are further described in detail.

[0030] A locking assembly 1, such as Figure 1 , Figure 2As shown, it includes a mounting seat 11, a driving module 12 and a plurality of swing modules 13. The driving module 12 is disposed on the mounting seat 11, and the plurality of swing modules 13 are disposed around the outer peripheral side of the mounting seat 11 at intervals and are all rotatably connected to the outer peripheral side of the mounting seat 11. The driving module 12 is used to simultaneously drive the plurality of swing modules 13 to swing so that the swing modules 13 lock or release the locking portion 2.

[0031] Please refer to Figure 1 , Figure 3 In this embodiment, a receiving cavity is provided in the mounting seat 11, and one end of the mounting seat 11 is used to install the locking portion 2. Specifically, the mounting seat 11 includes a mounting portion 111 and a supporting portion 112. The mounting portion 111 and the supporting portion 112 are both configured as cylindrical structures, and the diameter of the mounting portion 111 is larger than the diameter of the supporting portion 112, which saves costs. An arc-shaped guide groove 113 is provided at one end of the mounting portion 111 close to the supporting portion 112, and an avoidance groove 114 that penetrates inside and outside is provided at the position corresponding to the guide groove 113 at one end of the supporting portion 112 connected to the mounting portion 111. The end of the supporting portion 112 away from the mounting portion 111 is connected to the locking portion 2.

[0032] In this embodiment, the driving module 12 includes a driving unit 121 and a cam 122. The driving unit 121 is disposed on the mounting seat 11, and the cam 122 is disposed in the accommodating cavity. The driving unit 121 is used to drive the cam 122 to rotate around its axis by a set angle so that the cam 122 rotates by the length of a track surface 1221. The cam 122 is configured as a circular structure, and a plurality of track surfaces 1221 with gradually changing curvatures are sequentially disposed on the circumferential side of the cam 122.

[0033] Please refer to Figure 3 , Figure 4 The driving unit 121 includes a driving motor, a fixed gear 1211, a transmission gear 1212 and a connecting rod. The fixed gear 1211 is fixedly arranged at the bottom of the accommodating chamber, and the fixed gear 1211 is arranged coaxially with the cam 122. The output shaft of the driving motor is fixedly connected to the transmission gear 1212, and the outer peripheral side of the transmission gear 1212 is meshedly connected with the outer peripheral side of the fixed gear 1211, which can ensure that the movement path of the transmission gear 1212 rotates coaxially around the cam 122. One end of the connecting rod is fixedly connected to the transmission gear 1212, and one end of the connecting rod is connected to the cam 122. The driving motor drives the cam 122 to rotate around the axis through the transmission gear 1212 and the connecting rod, thereby improving the transmission accuracy. Among them, the structure of the driving motor is not drawn in the figure.

[0034] The connecting rod portion includes a first connecting rod 1213, a second connecting rod 1214 and a connecting shaft 1215. The first connecting rod 1213 and the connecting shaft 1215 are arranged vertically, and the second connecting rod 1214 is arranged horizontally. One end of the first connecting rod 1213 is connected to the transmission gear 1212, and the other end of the first connecting rod 1213 is connected to one end of the second connecting rod 1214. The other end of the second connecting rod 1214 is fixedly connected to one end of the connecting shaft 1215, and the cam 122 is fixedly connected to the other end of the connecting shaft 1215. The connecting shaft 1215 is rotatably connected to the mounting seat 11, and the structure is compact and the working space is staggered.

[0035] Specifically, the other end of the first connecting rod 1213 passes through the guide groove 113 and is connected to one end of the second connecting rod 1214. The other end of the second connecting rod 1214 passes through the avoidance groove 114 and is fixedly connected to one end of the connecting shaft 1215. The structure is compact, space is reasonably utilized, and the occupied space is reduced.

[0036] Wherein, a guide groove 113 is provided at both ends of the mounting portion 111, which can improve the running accuracy of the transmission gear 1212, thereby improving the working efficiency and accuracy of locking or separation.

[0037] Please refer to Figure 1 , Figure 3 In this embodiment, each set of swing modules 13 is provided with a corresponding track surface 1221. One end of the swing module 13 is in contact with the track surface 1221 of the cam 122, and the other end of the swing module 13 is locked and connected with the locking portion 2 or is separated. In this embodiment, the swing modules 13 and the track surface 1221 are provided in three sets.

[0038] When the lower end of the swing module 13 abuts against the minimum curvature radius position of the track surface 1221, the other end of the swing module 13 is locked and connected with the locking portion 2. When the lower end of the swing module 13 abuts against the maximum curvature radius position of the track surface 1221, the other end of the swing module 13 is separated from the locking portion 2.

[0039] Specifically, the swing module 13 includes a swing rod 131, a push rod 134 and a reset member 135. The swing rod 131 is rotatably arranged on the outside of the mounting seat 11, one end of the push rod 134 is fixedly connected to one end of the swing rod 131, and the other end of the push rod 134 passes through the mounting seat 11 and is abutted against the track surface 1221. A reset member 135 is arranged between the other end of the swing rod 131 and the side surface of the mounting seat 11, and the other end of the swing rod 131 is locked or separated with the locking part 2, thereby improving the locking or separation efficiency. The reset member 135 can be set as a spring structure.

[0040] The swing module 13 further includes two lugs 132 and a shaft 133 . The two lugs 132 are spaced apart on the outer peripheral side of the mounting base 11 . The swing rod 131 is rotatably connected between the two lugs 132 via the shaft 133 . The installation and disassembly is convenient, and replacement and maintenance are easy.

[0041] The other end of the swing rod 131 is bent to form a hook 1311, and the thickness of the hook 1311 gradually decreases in the direction away from the swing rod 131, which saves costs and improves the locking efficiency. The angle between the side of the hook 1311 facing the mounting seat 11 and the side of the swing rod 131 facing the mounting seat 11 is set to an obtuse angle, which facilitates the swing rod 131 to swing.

[0042] When the locking part 2 needs to be locked, the driving motor drives the transmission gear 1212 to rotate, and the transmission gear 1212 rotates around the axis of the cam 122 under the action of the guide groove 113 and the fixed gear 1211. Synchronously, driven by the first connecting rod 1213, the second connecting rod 1214, and the connecting shaft 1215, the cam 122 rotates around the axis, so that the end of the push rod 134 abuts against the position of the maximum curvature radius and the end of the push rod 134 abuts against the position of the minimum curvature radius. Under the action of the cam 122, the push rod 134 moves toward the outside of the mounting seat 11, thereby pushing the swing rod 131 to rotate, and the hook 1311 of the swing rod 131 clamps the locking part 2, and the reset member 135 is compressed.

[0043] When the locking part 2 needs to be released, the driving motor reverses to drive the transmission gear 1212, the first connecting rod 1213, and the second connecting rod 1214 to move, and the cam 122 also reverses and returns to its initial state. The position of the maximum curvature radius of the cam 122 is located at the end of the push rod 134. At this time, the force of the cam 122 on the push rod 134 is cancelled, and the swing rod 131 is pushed to swing in the opposite direction under the restoring force of the reset member 135. The hook 1311 is separated from the locking part 2, and the swing rod 131 is pushed by the reset member 135 to contact and connect with the position of the maximum curvature radius of the cam 122.

[0044] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
