Terms such as "upper," "lower," "above," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.
[0027] Please see Figure 1 as well as Figure 2 This application provides a locking component 100 for locking with a workpiece 50, and the locking component 100 can unlock the workpiece 50 from two directions.
[0028] Please refer to the following: Figure 3 In one specific embodiment, the workpiece 50 has a locking hole 51. The locking assembly 100 includes a tray 10, a movable component 20, and an unlocking handle 30. The tray 10 is located on the surface of the workpiece 50, the movable component 20 is movably inserted through the tray 10 and the workpiece 50, and the unlocking handle 30 is inserted through the movable component 20. The workpiece 50 can be unlocked from the tray 10 by pulling the movable component 20 from a first direction to remove it from the locking hole 51; or the unlocking handle 30 can be pulled from a second direction different from the first direction to move the movable component 20 and remove it from the locking hole 51. In this embodiment, the first and second directions are described as being perpendicular to each other. In other embodiments, the first and second directions are not limited to being perpendicular; they only need to be different.
[0029] The tray 10 includes a base plate 11, on which a first through hole 112 is provided. The first through hole 112 penetrates the two opposite surfaces of the base plate 11, and the position of the first through hole 112 corresponds to that of the locking hole 51.
[0030] For ease of explanation, the plane containing the base plate 11 is defined as the XY plane, and the pallet 10 and the workpiece 50 are stacked along the Z-axis.
[0031] The movable component 20 includes a sleeve 21, a pin 23, an elastic element 25, and an unlocking cover 27. The movable component 20 passes through the first through hole 112 and the locking hole 51 along the Z-axis.
[0032] The sleeve 21 is generally hollow and cylindrical. The sleeve 21 includes a first main body portion 212 and a blocking portion 214. The sleeve 21 has a receiving hole 216 that penetrates both the first main body portion 212 and the blocking portion 214. The blocking portion 214 extends from one end of the first main body portion 212 toward the receiving hole 216, meaning the inner diameter of the blocking portion 214 is smaller than the inner diameter of the first main body portion 212. The side of the first main body portion 212 opposite to the blocking portion 214 can be riveted into a first through hole 112, thus the sleeve 21 is detachably and fixedly connected to the tray 10. The first through hole 112 can be non-circular to ensure a fixed angle for the sleeve 21 when assembled in the tray 10, facilitating proper fit during subsequent component assembly.
[0033] The pin 23 includes a rod portion 232 and a cover portion 234. The cover portion 234 is disposed around the outer periphery of the rod portion 232 and is coaxially arranged with the rod portion 232. The rod portion 232 extends relative to the cover portion 234 along the Z-axis, and the diameter of the cover portion 234 is larger than the diameter of the rod portion 232. The pin 23 passes through the receiving hole 216 into the sleeve 21, the rod portion 232 passes through the blocking portion 214, and the cover portion 234 is located at the end of the rod portion 232 facing the workpiece 50. The end of the rod portion 232 away from the cover portion 234 can protrude from the receiving hole 216. The pin 23 can move relative to the sleeve 21 along the Z-axis. The diameter of the cover portion 234 is equal to or smaller than the inner diameter of the locking hole 51. The pin 23 can protrude from the tray 10 and be received in the locking hole 51 to limit the workpiece 50; the pin 23 can also be removed from the locking hole 51 to unlock the workpiece 50.
[0034] The elastic element 25 is elastic and can be a spring, an elastic polymer material, etc. In this embodiment, the elastic element 25 is a spring. The elastic element 25 is housed in the first main body 212 and sleeved on the rod 232. The two ends of the elastic element 25 abut against the cover 234 and the blocking part 214, respectively.
[0035] The diameter of the cover portion 234 is smaller than the inner diameter of the first main body portion 212, and the diameter of the cover portion 234 is larger than the inner diameter of the blocking portion 214. When the pin 23 is subjected to an external force, the cover portion 234 can be accommodated in the first main body portion 212 and compress the elastic member 25 located in the first main body portion 212; when the external force is removed, the pin 23 can return to its initial position under the restoring force of the elastic member 25.
[0036] The unlocking cover 27 is fixedly mounted on the end of the rod 232 opposite to the cover 234. When an external force is applied to the unlocking cover 27, the unlocking cover 27 is displaced, which causes the pin 23 fixed to the unlocking cover 27 to be displaced relative to the sleeve 21.
[0037] The periphery of the unlock cover 27 is designed with knurling 274 to facilitate the application of force by the user.
[0038] The surface of the unlock cover 27 facing the cover portion 234 is an inclined surface. In this embodiment, the inclined surface is a first conical surface 272. The end of the first conical surface 272 that is close to the cover portion 234 is closer to the rod portion 232, and the end that is away from the cover portion 234 is farther from the rod portion 232. That is, the top of the first conical surface 272 is close to the side where the cover portion 234 is located.
[0039] The unlocking handle 30 is located between the unlocking cover 27 and the sleeve 21. The unlocking handle 30 and the unlocking cover 27 are connected to each other, and the surfaces that are connected to each other are all inclined surfaces, which are inclined towards the base plate 11 along the Z-axis.
[0040] Please refer to the following: Figure 4 The unlocking handle 30 includes a second main body 31, a limiting hook 33, and a locking hook 35. The limiting hook 33 and the locking hook 35 are both fixed on the second main body 31. In this embodiment, the second main body 31, the limiting hook 33, and the locking hook 35 are an integral structure.
[0041] The second main body 31 has an opening 312, which includes a first region 3121 and a second region 3122 arranged along the X-axis and interconnected, with the sizes of the first region 3121 and the second region 3122 decreasing sequentially. The second main body 31 includes a first extension 314 and a second extension 316. The first extension 314 surrounds the first region 3121, and the second extension 316 surrounds the second region 3122. The first extension 314 protrudes from the first region 3121, and the second extension 316 protrudes from the second region 3122. When the unlocking handle 30 is assembled with the tray 10 and the movable component 20, the first extension 314 is located between the unlocking cover 27 and the sleeve 21. When a force is applied to the unlocking handle 30 along the X-axis, the unlocking cover 27 slides relative to the rod 232 along the Z-axis, and the rod 232 passes through the second region 3122.
[0042] The opening 312 also includes a third section 3123, which is located on the side of the first section 3121 opposite to the second section 3122 and communicates with the first section 3121. The size of the third section 3123 is larger than the size of the unlocking cover 27. After the movable component 20 is fixed on the tray 10, the third section 3123 allows the unlocking cover 27 to pass through so that the unlocking handle 30 can be fitted onto the movable component 20.
[0043] Both the first extension 314 and the second extension 316 have inclined surfaces facing the unlocking cover 27. The inclined surface of the first extension 314 can fit against the inclined surface of the unlocking cover 27, and the inclined surface of the second extension 316 can contact the inclined surface of the unlocking cover 27. In this embodiment, the surface of the first extension 314 facing the unlocking cover 27 is a second conical surface 3142, and the surface of the second extension 316 facing the unlocking cover 27 is a third conical surface 3162. The second conical surface 3142 and the third conical surface 3162 are connected, and both the second conical surface 3142 and the third conical surface 3162 are adapted to the first conical surface 272 of the unlocking cover 27. When the locking assembly 100 is locked to the workpiece 50, the first conical surface 272 is in contact with the second conical surface 3142. When an external force is applied to the unlocking handle 30, the unlocking handle 30 is displaced relative to the unlocking cover 27, so that the unlocking cover 27 is displaced relative to the sleeve 21. The second conical surface 3142 abuts against the first conical surface 272 and causes the first conical surface 272 to move toward the third conical surface 3162. When in the unlocked state, the first conical surface 272 is in contact with the third conical surface 3162.
[0044] The limiting hook 33 extends along the X-axis relative to the second main body 31, and the tray 10 also has a second through hole 114. The position of the limiting hook 33 is adapted to the position of the second through hole 114. When the unlocking handle 30 is assembled with the tray 10 and the movable component 20, the limiting hook 33 is engaged in the second through hole 114. The limiting hook 33 and the second through hole 114 interact to limit the unlocking handle 30 and prevent the unlocking handle 30 from rotating around the Z-axis.
[0045] The hook 35 is disposed on the surface of the second main body 31 and protrudes along the Z-axis relative to the second main body 31. A force can be applied to the hook 35 along the X-axis by the tool 40, so that the unlocking handle 30 is displaced relative to the tray 10 and the movable component 20.
[0046] The following describes the relationship between the various components of the locking assembly 100 of this application through specific locking and unlocking processes.
[0047] When the locking assembly 100 is used to lock the workpiece 50, the movable assembly 20 is inserted into the tray 10 through the first through hole 112, the sleeve 21 is fixed to the base plate 11, the cover 234 protrudes from the base plate 11 and is accommodated in the locking hole 51 of the workpiece 50, and the unlocking cover 27 is located on the side of the base plate 11 away from the cover 234. The unlocking handle 30 is passed through the unlocking cover 27 through the first area 3121 of the opening 312, and the unlocking handle 30 is pulled along the X-axis, so that the movable assembly 20 passes through the unlocking handle 30 through the first area 3121. At this time, the first extension 314 is located between the unlocking cover 27 and the sleeve 21, the first conical surface 272 and the second conical surface 3142 are in contact with each other, the limiting hook 33 is located in the second through hole 114, and the locking assembly 100 and the workpiece 50 are locked.
[0048] Please see Figure 5 When the locking assembly 100 and the workpiece 50 are unlocked along the Z-axis direction (i.e., the first direction), a force F1 is applied to the unlocking cover 27 along the Z-axis direction. The pin 23, which is fixedly connected to the unlocking cover 27, moves along the Z-axis direction, and the cover 234 moves relative to the sleeve 21 to enter the first main body 212. The cover 234 then moves out of the locking hole 51, thus unlocking the locking assembly 100 and the workpiece 50. At this time, the elastic element 25 in the first main body 212 is compressed. When the force F1 applied to the unlocking cover 27 is removed, under the restoring force of the elastic element 25, the pin 23 causes the cover 234 to extend out of the first main body 212 to return to its initial position, achieving automatic return.
[0049] Please see Figure 6When the locking assembly 100 and the workpiece 50 are unlocked along the X-axis (i.e., the second direction), the tool 40 hooks the latch 35 and applies a force F2 along the X-axis, causing the unlocking handle 30 to tend to move along the X-axis. At this time, the second conical surface 3142 has a force that resists the first conical surface 272 and causes the third conical surface 3162 to move toward the first conical surface 272, causing the unlocking cover 27 to move along the Z-axis. The movement of the unlocking cover 27 drives the pin 23, which is fixed relative to the unlocking cover 27, to move synchronously along the Z-axis. The cover 234 moves relative to the sleeve 21 and enters the first main body 212, then moves out of the locking hole 51, thus unlocking the locking assembly 100 and the workpiece 50. At this time, the rod 232 protrudes from the sleeve 21, causing the unlocking handle 30 to move relative to the tray 10 along the X-axis. The rod 232 enters the second area 3122, and the first conical surface 272 contacts the third conical surface 3162. When the force F2 applied to the unlocking handle 30 is removed, the restoring force of the elastic element 25 causes the cover 234 to extend from the first main body 212 and return to its initial position. During the process of the pin 23 returning to its initial position, the distance between the unlocking cover 27 and the sleeve 21 gradually decreases, and the third conical surface 3162 causes the first conical surface 272 to move towards the second conical surface 3142 until the rod 232 passes through the first area 3121, and the first conical surface 272 and the second conical surface 3142 are in contact, achieving automatic return. Among them, the inclined surfaces that come into contact with each other are conical surfaces (i.e., the first conical surface 272, the second conical surface 3142, and the third conical surface 3162). During the process of pulling the unlocking handle 30, the force of the unlocking handle 30 driving the unlocking cover 27 to move is relatively smooth, improving the user's feel.
[0050] Please refer to it again. Figure 3 The tray 10 also includes a side plate 13, which extends relative to the base plate 11 along the Z-axis. Two limiting grooves 132 are provided on the side plate 13, arranged along the Y-axis. In other embodiments, the number of limiting grooves 132 can be one or more. The first main body 212 can be engaged in the limiting groove 132, which limits the movement of the unlocking handle 30 along the X-axis.
[0051] The outer wall of the sleeve 21 is provided with grooves 218 on both sides, and the grooves 218 are arranged along the X-axis. The second main body 31 also includes a slide rail, which is disposed in the opening 312 and extends along the X-axis. The slide rail is adapted to the groove 218 and can slide relative to the groove 218 along the X-axis to limit the movement of the unlocking handle 30 along the X-axis.
[0052] The locking assembly 100 provided in this application includes a tray 10, a movable component 20, and an unlocking handle 30. The movable component 20 includes a sleeve 21, a pin 23, and an unlocking cover 27. The pin 23 is movably disposed in the sleeve 21, thereby confining the workpiece 50 on the tray 10. The unlocking handle 30 is located between the sleeve 21 and the unlocking cover 27, and the unlocking handle 30 is provided with an inclined surface adapted to the unlocking cover 27. On one hand, the pin 23 can be pulled directly to unlock; on the other hand, the unlocking handle 30 can be pulled, and the inclined surface of the unlocking handle 30 adapted to the unlocking cover 27 causes the unlocking cover 27 to move the pin 23, thereby unlocking. The locking assembly 100 provided in this application embodiment can be unlocked in two directions, improving the applicability of the locking assembly 100.
[0053] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
