[0012] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are one embodiment of this invention, and not all embodiments. Based on the described embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0013] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.
[0014] This embodiment first provides a locking mechanism 300 for the force-bearing component 100. Figure 1 This is a cross-sectional view of a locking mechanism 300 according to some embodiments of this application. Figure 2 This is a top view of a locking mechanism 300 according to some embodiments of this application; Figure 3 This is a top view of a locking assembly according to some embodiments of this application; Figure 4 This is a side view of a locking assembly according to some embodiments of this application; Figure 5 This is a perspective view of a locking assembly according to some embodiments of this application.
[0015] The force-bearing component 100 includes a main body 110 and a cover 120 detachably connected to the main body 110. The main body 110 has a locking hole. Understandably, the main body 110 of the force-bearing component 100 can be a box, which can be a box for containing objects or a shearing box for cutting objects. For safety reasons, to protect the objects or internal components of the box, in certain working conditions, such as when the box is not in use, it is necessary to lock the box and the cover 120 together. In other embodiments, the main body 110 may not be a box, but rather various blocks, plates, etc.
[0016] like Figure 1 as well as Figure 2As shown, the locking mechanism 300 includes a mounting plate 310, at least one fixing block 320, at least one slider 330, and at least one lifting lug 390.
[0017] The mounting plate 310 is used to install onto the cover 120, and the mounting plate 310 serves as the mounting base for other components of the locking mechanism 300.
[0018] Each fixing block 320 is fixed to the mounting plate 310, and each fixing block 320 has a sliding hole. The at least one slider 330 corresponds one-to-one with the at least one fixing block 320 (understandably, in this embodiment, one-to-one correspondence means that the number of both is equal, and each one has a corresponding other). Each slider 330 is slidably disposed in the corresponding sliding hole, and each slider 330 is configured to have a locked state with a portion located outside the sliding hole. When any slider 330 is in the locked state, the portion of each slider 330 located outside the sliding hole extends in a tapering manner from the area near the sliding hole to the area away from the sliding hole. The portion of each slider 330 located outside the sliding hole is used to pass through the locking hole to lock the main body 110 and the cover 120. Furthermore, in order to enable remote assembly and disassembly of the locking mechanism 300 itself, the locking mechanism 300 also includes at least one lifting lug 390, which corresponds one-to-one with the at least one fixing block 320. Each lifting lug 390 is fixed to the corresponding fixing block 320, and each lifting lug 390 has a lifting hole. Each lifting hole is used to connect to an external lifting component, thereby receiving the lifting force applied by the external lifting component.
[0019] The portion of slider 330 located outside the sliding hole is used to pass through the locking hole. When the main body 110 moves away from the cover 120, slider 330, by passing through the locking hole, restricts the movement of the main body 110 away from the cover 120, thereby achieving locking.
[0020] Specifically, the cover 120 has at least one through hole, which corresponds one-to-one with the at least one slider 330. The cover 120 also has at least one protrusion 122, which corresponds one-to-one with the at least one slider 330. Each protrusion 122 is used to abut against the corresponding slider 330 when it is in the locked state. The main body 110 also includes a base plate 111 and at least one locking plate 112, which corresponds one-to-one with the at least one through hole. Each locking plate 112 has a locking hole, and each locking plate 112 is fixed to the base plate 111 and passes through the corresponding through hole. Each slider 330 passes through the corresponding locking hole when it is in the locked state.
[0021] like Figure 3 , Figure 4 as well as Figure 5As shown, the slider 330 extends outward and contacts the inclined hole wall of the locking hole on the locking plate 112 and the protrusion 122 on the cover 120, thereby locking the two components, the base plate 111 and the cover 120. The more the slider 330 extends, the greater the locking force. Understandably, the base plate 111 can be part of the aforementioned housing.
[0022] In some embodiments, at least one guide block 200 may be provided on the cover 120, each guide block 200 being fixed to the cover 120. The guide block 200 is used to guide the installation position of the mounting plate 310 when the mounting plate 310 of the locking mechanism 300 is installed onto the cover 120. Specifically, a guide ramp is provided in the middle of the cover 120 to guide and engage the mounting plate 310 of the locking mechanism 300, enabling guidance and positioning of the locking mechanism 300 during long-distance reinstallation. In some embodiments, there may be one guide block 200, which may have a guide groove for guidance and positioning. In other embodiments, there may be a pair of guide blocks 200, which together form guidance and positioning during long-distance installation. It is understood that in other embodiments, there may also be other numbers of guide blocks 200.
[0023] Since the portion of each slider 330 outside the sliding hole gradually narrows from the area near the sliding hole to the area away from the sliding hole, the slider 330 becomes increasingly tighter with the locking hole as it moves outward, achieving the locking effect between the main body 110 and the cover 120.
[0024] In some embodiments, when any slider 330 is in a locked state, the shape and size of the cross-sections at any two locations within the sliding hole are equal, and the cross-sections are perpendicular to the extension direction of the corresponding sliding hole.
[0025] When any slider 330 is in the locked state, the part located inside the sliding hole mainly provides support for the sliding of slider 330. The fact that the cross-sectional shape and size of any two points inside the sliding hole are equal makes the sliding of slider 330 more stable.
[0026] Each slider 330 includes a first end face, a second end face, a first side face, a second side face, and a third side face.
[0027] The first end face is perpendicular to the extension direction of the corresponding sliding hole, and when either slider 330 is in the locked state, the first end face is located inside the sliding hole. The second end face is perpendicular to the extension direction of the corresponding sliding hole, and when either slider 330 is in the locked state, the second end face is located outside the sliding hole. The first side face connects the end of the first end face near the cover 120 and the end of the second end face near the cover 120, and the first side face is perpendicular to both the first and second end faces. One end of the second side face connects to the end of the first end face away from the cover 120, and in the extension direction of the corresponding sliding hole, the size of the second side face is smaller than the size of the first side face. The first end of the third side face connects to the other end of the second side face, and the second end of the third side face connects to the end of the second end face away from the cover 120, and the distance between the first end of the third side face and the first side face is greater than the distance between the second end of the third side face and the first side face.
[0028] In other words, the slider 330 can be a wedge-tight slider, which facilitates locking force. Since the locking mechanism is connected to the cover 120, the positional relationship between the slider 330 of the locking mechanism and the locking hole of the main body 110 can easily change significantly. By making the third side that contacts the hole wall of the locking hole an inclined surface (understandably, the hole wall of the locking hole is also an inclined surface), it is easier to make the hole wall of the locking hole closely contact the third side during the movement of the slider 330, thereby achieving the locking effect of the main body 110 and the cover 120.
[0029] Understandably, any slider 330 may also include a fourth side and a fifth side. The fourth side connects the first end of the first end face, the first end of the second end face, the first end of the first side, the first end of the second side, and the first end of the third side. The fifth side connects the second end of the first end face, the second end of the second end face, the second end of the first side, the second end of the second side, and the second end of the third side. The cross-section can be rectangular.
[0030] The locking mechanism 300 may further include at least one transmission rod 340, which corresponds one-to-one with the at least one slider 330. One end of each transmission rod 340 is connected to the corresponding slider 330, and the other end of each transmission rod 340 is used to receive the transmission force. Each transmission rod 340 is used to transmit the transmission force to the corresponding slider 330 so that the corresponding slider 330 slides in the corresponding sliding hole.
[0031] The transmission rod 340 can be a lead screw shaft. The setting of the transmission rod 340 allows the slider 330 to be controlled from a distance away from the slider 330.
[0032] Specifically, each transmission rod 340 has an external thread on its outer surface (this thread may only be present at the end connected to the slider 330, rather than on the entire outer surface of the transmission rod 340), and each slider 330 has a threaded hole. One end of each transmission rod 340 connects to the threaded hole of the corresponding slider 330 through the external thread. The transmission force causes the transmission rod 340 to rotate, thereby driving the corresponding slider 330 to slide through the engagement of the external and internal threads. At this time, the transmission rod 340 itself does not perform translational motion; it only rotates. This avoids interference to other components caused by the translation of the transmission rod 340, and when there are multiple transmission rods 340, it can prevent mutual interference between them.
[0033] The locking mechanism 300 may further include a transmission box 350 and a rotating shaft 360. The transmission box 350 is fixed to the mounting plate 310 and defines a receiving cavity. At least one first bevel gear 351 and a second bevel gear 352 are disposed in the receiving cavity. The second bevel gear 352 meshes with each first bevel gear 351. Each first bevel gear 351 corresponds to one of the at least one transmission rod 340. The receiving cavity has at least one first opening and a second opening. Each first opening corresponds to one of the at least one transmission rod 340, and the other end of each transmission rod 340 enters the receiving cavity through the corresponding first opening to connect with the corresponding first bevel gear 351. The first end of the rotating shaft 360 is connected to the second bevel gear 352 in the receiving cavity through the second opening, and the second end of the rotating shaft 360 is located outside the receiving cavity. The rotating shaft 360 transmits power to each transmission rod 340 through each first bevel gear 351 and the second bevel gear 352.
[0034] The transmission box 350 can be a gearbox. The arrangement of the transmission box 350 and the rotating shaft 360 changes the direction of the transmission force, making it easier to apply the transmission force. When there are multiple transmission rods 340, the same amount of transmission force can be applied to multiple transmission rods 340 at the same time, simplifying the operation.
[0035] The locking mechanism 300 may further include a rotating wheel 370, which is connected to the second end of the rotating shaft 360. The rotating wheel 370 receives external power and transmits the power to the rotating shaft 360. The external power can be provided by a robotic arm, and the rotating wheel 370 facilitates robotic arm operation. The rotating wheel 370 and the second end of the rotating shaft 360 can be connected via a clearance fit, further simplifying operation.
[0036] Understandably, the main body 110 and the cover 120 can be placed in an environment containing radioactive materials. In this case, it is inconvenient for personnel to enter the space around the main body 110 and the cover 120 to apply power transmission. The setting of the rotating wheel 370 facilitates the application of power transmission by the robotic arm, making this locking mechanism 300 particularly suitable for this scenario.
[0037] In some embodiments, the at least one fixing block 320 includes a first fixing block 320 and a second fixing block 320, and the first fixing block 320, the second fixing block 320, and the transmission box 350 are arranged in a straight line. Specifically, the first fixing block 320 and the second fixing block 320 are symmetrically arranged on the left and right sides of the transmission box 350. It can be understood that the first fixing block 320 and the second fixing block 320 are respectively equipped with components such as a slider 330 and a transmission rod 340. This arrangement allows the main body 110 and the cover 120 to be locked more tightly, which is particularly suitable for scenarios where the main body 110 and the cover 120 are large.
[0038] The locking mechanism 300 may further include at least one limiting block 380, which corresponds one-to-one with the at least one transmission rod 340. Each limiting block 380 is mounted on the mounting plate 310, and each limiting block 380 has a limiting hole. Each transmission rod 340 passes through the limiting hole of the corresponding limiting block 380. The limiting blocks 380 can keep the transmission shaft stable during rotation.
[0039] Specifically, each limit block 380 includes a fixing plate and a limiting plate. The fixing plate is fixed to the mounting plate 310. The limiting plate extends from the end of the fixing plate near the corresponding fixing block 320 away from the mounting plate 310, and the limiting plate has a limiting hole. Thus, the limiting plate can be closer to the fixing block 320, thereby limiting the transmission rod 340 at the position near the slider 330, ensuring the limiting effect.
[0040] This embodiment also provides a locking assembly 10, which includes a force-bearing component 100 and any of the locking mechanisms 300 described above. The force-bearing component 100 includes a main body 110 and a cover 120 detachably connected to the main body 110. The main body 110 has a locking hole; the locking mechanism 300 is installed on the cover 120.
[0041] The cover 120 has at least one through hole, which corresponds to at least one slider 330. The cover 120 also has at least one protrusion 122, which corresponds to at least one slider 330. Each protrusion 122 is used to abut against the corresponding slider 330 when it is in the locked state. The main body 110 also includes a base plate 111 and at least one locking plate 112, which corresponds to at least one through hole. Each locking plate 112 has a locking hole. Each locking plate 112 is fixed to the base plate 111 and passes through the corresponding through hole. Each slider 330 passes through the corresponding locking hole when it is in the locked state.
[0042] Specifically, when the rotating wheel 370 is rotated forward, the slider 330 extends outward, contacting the inclined wall of the locking hole on the locking plate 112 and the protrusion 122 on the cover 120, thereby locking the base plate 111 and the cover 120. The more the slider 330 extends, the greater the locking force. Understandably, the base plate 111 can be part of the aforementioned housing.
[0043] In some embodiments, the locking assembly 10 may further include at least one guide block 200, each guide block 200 being fixed to the cover 120. The guide block 200 is used to guide the mounting plate 310 of the locking mechanism 300 to the installation position when the mounting plate 310 of the locking mechanism 300 is installed onto the cover 120. Specifically, a guide ramp is provided in the middle of the cover 120 to guide and engage the mounting plate 310 of the locking mechanism 300, enabling guidance and positioning of the locking mechanism 300 during long-distance reinstallation.
[0044] In this embodiment, when the main body 110 and the cover 120 of the locking assembly 10 are to be locked, the lifting lug 390 is first used to place the locking mechanism 300 on the cover 120. During the placement process, the locking mechanism 300 is guided by the guide block 200. The robot rotates the rotating wheel 370, and then the rotating shaft 360 rotates. Driven by the first bevel gear 351 and the second bevel gear 352, the transmission rod 340 starts to rotate, so that the slider 330 extends out of the sliding hole and then contacts the locking hole and the protrusion 122 and is subjected to locking force, thereby locking the two components, the base plate 111 and the cover 120. As the slider 330 extends further, the locking force is greater, thereby achieving the locking of the main body 110 and the cover 120. When the lock needs to be released, the robotic arm rotates the rotating wheel 370 again, but in the opposite direction to the previously mentioned direction. Then, the rotating shaft 360 rotates in the opposite direction. Driven by the first bevel gear 351 and the second bevel gear 352, the transmission rod 340 begins to rotate in the opposite direction, causing the slider 330 to retract into the sliding hole. Once the slider 330 has retracted completely, the main body 110 and the cover 120 are unlocked. When the locking mechanism 300 malfunctions and needs to be replaced, the lifting lug 390 can be used for remote disassembly and assembly of the locking mechanism 300, allowing for the replacement of the new locking mechanism 300.
[0045] Regarding the embodiments of the present invention, it should also be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other to obtain new embodiments.
[0046] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
