Description
A hoisting lock structure Technical Field
[0001] This invention relates to the technical field of connection structures, and more particularly to a hoisting lock structure. Background Technology
[0002] During the filming of television, movies, stage performances, and content creation (YouTubers, TikTok, etc.), lighting equipment is needed to illuminate the filming scene. Lighting equipment is usually equipped with clamps for installation. The clamps include a connecting rod connected to the main body of the light fixture, and a pipe clamp connected to one axial end of the connecting rod. The pipe clamp can be clamped onto a horizontal pipe or rod to suspend the lighting equipment.
[0003] In existing technologies, lighting equipment is generally installed using a hoisting structure. However, with the rapid development of the film and television industry, more stringent requirements have been placed on the response and safety of lighting during filming. For example, lighting equipment needs to be installed or disassembled quickly during on-site setup, and the lighting direction needs to be adjusted in a timely manner when the lights are in use. At the same time, the safe use of the lighting equipment must be ensured. Therefore, the connection structure of hoisted lighting equipment has been required to be convenient to install and disassemble, flexible to adjust, and safe to use. To this end, it is necessary to improve the ease of installation and disassembly, flexibility of adjustment, and safety performance of the hoisting lock structure. Summary of the Invention
[0004] The purpose of this invention is to provide a lifting lock structure that addresses the difficulty in balancing ease of assembly and disassembly with enhanced security during use.
[0005] To solve the above technical problems, a lifting lock structure is provided, including a clamping member, a connecting assembly, a plugging assembly, and a connecting seat; the connecting assembly includes a limiting sleeve and a handle, the limiting sleeve being connected to the clamping member, and the handle being fitted onto the limiting sleeve; the plugging assembly includes a plug-in member, a lock cylinder, and a pin, the plug-in member being rotatably connected to the clamping member, and one end of the plug-in member being located between the handle and the limiting sleeve, the lock cylinder being fitted onto one side of the plug-in member, the lock cylinder being connected to the plug-in member via the pin, and the pin elastically abutting against the handle; the connecting seat forms a limiting hole and a first clearance hole, the first clearance hole... The holes are located on both sides of the limiting hole, and the limiting hole allows the other end of the plug-in member to be disassembled and connected; wherein, the lock cylinder includes a first lock body and a second lock body, the first lock body and the second lock body are connected by the pin, the plug-in member forms a second clearance hole, when the pin is engaged with the handle, the pin passes through the second clearance hole; the clamping member forms a second through hole, the second lock body moves in the second through hole, when the end of the first lock body is located in the first clearance hole and the plug-in member locks the limiting hole, the end of the second lock body is flush with the second through hole, so as to restrict the plug-in member from unlocking the limiting hole.
[0006] Furthermore, the insertion / removal component includes a locking body, an insertion / removal body, a locking head body, and a first rotating shaft. The locking body is located at one end of the insertion / removal body, and the locking head body is located at the other end of the insertion / removal body. The first rotating shaft body is connected between the insertion / removal body and the locking head body. When the first rotating shaft body passes through the limiting hole, the insertion / removal body is rotated so that the locking head body locks the limiting hole.
[0007] Furthermore, the end of the lock cylinder is movable on one side of the first rotating shaft, and the handle is formed with a first limiting groove and a second limiting groove that are rotated and misaligned. When the pin engages the handle and the handle moves toward the limiting sleeve, the locking body engages in the first limiting groove, and the end of the lock cylinder disengages from the first rotating shaft so that the first rotating shaft passes through the limiting hole.
[0008] Furthermore, when the lock body locks the limiting hole and the handle moves away from the limiting sleeve, the end of the lock cylinder returns to one side of the first rotating shaft body, and the end of the lock cylinder is located in the first clearance hole.
[0009] Furthermore, the plug-in assembly also includes a first limiting member, a second limiting member, and an elastic member. The plug-in body forms a groove. The first limiting member is connected to one side of the lock cylinder, the second limiting member is connected to the plug-in body, and the elastic member abuts between the first limiting member and the second limiting member. The first limiting member, the second limiting member, and the elastic member are all located in the groove.
[0010] Furthermore, the locking body is located between the handle and the limiting sleeve. When the plug is rotated, and the pin engages the handle and the handle moves toward the limiting sleeve, the locking body engages into the first limiting groove, so that the plug is driven into the limiting hole for locking. When the pin is movably connected to the handle and the handle moves toward the limiting sleeve, the locking body engages into the second limiting groove, so that the plug is movably connected to the limiting hole.
[0011] Furthermore, a first through hole is formed perpendicularly to the first limiting groove on the handle. When the plug-in component is rotated to the point where the card body is directly opposite the first limiting groove, the pin elastically engages with the first through hole, so that the pin is engaged with the handle.
[0012] Furthermore, the handle also has an annular guide groove, the first through hole is located in the annular guide groove, and the pin is movable in the annular guide groove.
[0013] Furthermore, the clamping member is provided with a ball bearing, and the insertion / removal member also includes a second rotating shaft. The second rotating shaft is connected to the end of the clamp body away from the insertion / removal member. The end of the second rotating shaft forms a plurality of positioning grooves. The ball bearing moves in each of the positioning grooves, and the second rotating shaft rotates relative to the limiting sleeve.
[0014] Implementing the embodiments of the present invention will have the following beneficial effects:
[0015] In this embodiment of the hoisting lock structure, the lock cylinder includes a first lock body and a second lock body, which are connected by a pin. The plug-in component also forms a second clearance hole, and the clamping component forms a second through hole. Thus, when the pin engages the handle, the pin passes through the second clearance hole, and the second lock body moves in the second through hole. Consequently, the end of the first lock body is located in the first clearance hole, and when the plug-in component locks the limiting hole, the end of the second lock body is flush with the second through hole to restrict the plug-in component from unlocking the limiting hole, thereby improving the security of the plug-in component locking and overcoming the problem that the existing hoisting lock structure is difficult to balance convenient disassembly and assembly and improved security during use.
[0016] In this embodiment of the hoisting lock structure, the plug-in component includes a plug-in body, a lock head body, and a first rotating shaft. The locking body is located at one end of the plug-in body, the lock head body is located at the other end of the plug-in body, and the first rotating shaft is connected between the plug-in body and the lock head body. The connecting seat also forms a first clearance hole, so that the pin engages with the handle. When the handle moves toward the limiting sleeve, the locking body engages with the first limiting groove, and the end of the lock cylinder disengages from the rotating shaft, allowing the first rotating shaft to pass through the limiting hole. The plug-in body is rotated, and when the handle moves away from the limiting sleeve, the end of the lock cylinder returns to one side of the first rotating shaft, and the end of the lock cylinder is located in the first clearance hole, so that the lock head body can easily lock the limiting hole.
[0017] In this embodiment of the hoisting lock structure, the handle has a first and second limiting groove with a rotational misalignment. One end of the plug-in component has a locking body located between the handle and the limiting sleeve. When the plug-in component is rotated, and the pin engages with the handle, and the handle moves toward the limiting sleeve, the locking body engages with the first limiting groove, thereby allowing the plug-in component to be inserted into the limiting hole for locking. When the pin is movably connected to the handle, and the handle moves toward the limiting sleeve, the locking body engages with the second limiting groove, thereby allowing the plug-in component to be movably connected to the limiting hole, thus enabling the plug-in component to be flexibly and conveniently adjusted relative to the connecting seat.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0036] Please refer to Figures 1-13. This embodiment of the invention provides a hoisting lock structure 100, including a clamping member 110, a connecting assembly 120, a plugging assembly 130, and a connecting seat 140. The connecting assembly 120 includes a limiting sleeve 121 and a handle 122. The limiting sleeve 121 is connected to the clamping member 110, and the handle 122 is fitted onto the limiting sleeve 121. The plugging assembly 130 includes a plug-in member 131, a lock cylinder 132, and a pin 133. The plug-in member 131 is rotatably connected to the clamping member 110, and one end of the plug-in member 131 is located between the handle 122 and the limiting sleeve 121. The lock cylinder 132 is fitted onto one side of the plug-in member 131 and is connected to the plug-in member 131 via the pin 133, which elastically abuts against the handle 122. The connecting seat 140 forms a limiting hole 141 and a first clearance hole 142. The first clearance hole 142 is located on both sides of the limiting hole 141, and the limiting hole 141 allows the other end of the plug-in member 131 to be disassembled and connected. The lock cylinder 132 includes a first lock body 1321 and a second lock body 1322, which are connected by a pin 133. The plug-in member 131 also has a second clearance hole 13121. When the pin 133 engages with the handle 122, the pin 133 passes through the second clearance hole 13121. The clamping member 110 forms a second through hole 111, and the second lock body 1322 moves in the second through hole 111. When the end of the first lock body 1321 is located in the first clearance hole 142 and the plug-in member 131 locks the limiting hole 141, the end of the second lock body 1322 is flush with the second through hole 111 to restrict the plug-in member 131 from unlocking the limiting hole 141.In practical applications, since the first lock body 1321 and the second lock body 1322 are connected by a pin 133, and the insertion / removal member 131 also forms a second clearance hole 13121, when the lock cylinder 132 rotates relative to the handle 122 with the insertion / removal member 131, the pin 133 can elastically pass through the second clearance hole 13121 and the first through hole 1223, thereby connecting the handle 122, the lock cylinder 132, and the insertion / removal member 131. Since the clamping member 110 forms a second through hole 111, and the second lock body 132 moves within the second through hole 111, it is worth noting that when the clamping member 110 is clamped to the outside, i.e., the hoisting structure is in working condition, it is necessary to improve the safety of the lighting equipment hoisting and avoid accidental detachment or safety hazards. Therefore, when the end of the first lock body 1321 is located in the first clearance hole 142 and the plug-in member 131 locks the limiting hole 141, the end of the second lock body 1322 is flush with the second through hole 111, and the end of the second through hole 111 is connected to the outside, such as contact with a tubular object. That is, the second lock body 1322 cannot pass through the second through hole 111. At this time, the handle 122 cannot be directly operated to unlock the limiting hole 141 of the connecting seat 140. Only when the clamping member 110 is separated from the contact object in the outside (by default, the hoisting lock structure 100 is not in working state) can the handle 122 be operated to unlock the limiting hole 141, thereby making the hoisting lock structure 100 have a secondary safety lock and improving the safety of the hoisting lock structure 100.
[0037] In one possible implementation, the plug-in component 131 includes a locking body 1311, a plug-in body 1312, a locking head body 1313, and a first rotating shaft 1314. The locking body 1311 is located at one end of the plug-in body 1312, and the locking head body 1313 is located at the other end of the plug-in body 1312. The first rotating shaft 1314 is connected between the plug-in body 1312 and the locking head body 1313. When the first rotating shaft 1314 passes through the limiting hole 141, the plug-in body 1312 is rotated so that the locking head body 1313 locks the limiting hole 141. In practical applications, since the card body 1311 is located at one end of the insertion body 1312 and the lock head body 1313 is located at the other end of the insertion body 1312, the first rotating shaft body 1314 is connected between the insertion body 1312 and the lock head body 1313. When the lock cylinder 132 is pulled out by the pin 133 through the handle 122, the first rotating shaft can pass through the limiting hole 141. Then, after rotating the insertion body 1312 to 90 degrees, the handle 122 is released, and the lock cylinder 132 elastically resets to constrain the free rotation of the insertion body 1312, thereby locking the lock head body 1313 in the limiting hole 141.
[0038] In one possible implementation, the end of the lock cylinder 132 is movable on one side of the first rotating shaft 1314, and the handle 122 is formed with a first limiting groove 1221 and a second limiting groove 1222 that are rotated and misaligned. When the pin 133 engages the handle 122 and the handle 122 moves toward the limiting sleeve 121, the locking body 1311 engages the first limiting groove 1221, and the end of the lock cylinder 132 disengages from the first rotating shaft 1314 so that the first rotating shaft 1314 passes through the limiting hole 141. In specific applications, since the end of the lock cylinder 132 is movable on one side of the first rotating shaft 1314, when the pin 133 engages the handle 122, and then the handle 122 moves toward the limiting sleeve 121, the locking body 1311 will engage with the first limiting groove 1221. At this time, the end of the lock cylinder 132 will disengage from the first rotating shaft 1314, thereby releasing the lock cylinder 132 from the constraint of the first rotating shaft 1314 passing through the limiting hole 141.
[0039] In one possible implementation, when the lock body 1313 locks the limiting hole 141 and the handle 122 moves away from the limiting sleeve 121, the end of the lock cylinder 132 returns to one side of the first rotating shaft 1314, and the end of the lock cylinder 132 is located in the first clearance hole 142. In specific applications, since the connecting seat 140 also forms the first clearance hole 142, and the first clearance hole 142 communicates with the limiting hole 141, after the first rotating shaft 1314 passes through the limiting hole 141, and then the plug-in body 1312 is rotated to 90 degrees, when the handle 122 moves away from (releases) the limiting sleeve 121, the end of the lock cylinder 132 elastically returns to one side of the first rotating shaft 1314, so that the end of the lock cylinder 132 is located in the first clearance hole 142 and locks the limiting hole 141, so that the lock body 1313 cannot rotate freely in the limiting hole 141 for locking.
[0040] In one possible implementation, the plug-in assembly 130 further includes a first limiting member 134, a second limiting member 135, and an elastic member (not shown). The plug-in body 1312 forms a groove 13122. The first limiting member 134 is connected to one side of the lock cylinder 132, the second limiting member 135 is connected to the plug-in body 1312, and the elastic member abuts between the first limiting member 134 and the second limiting member 135. The first limiting member 134, the second limiting member 135, and the elastic member are all located in the groove 13122. In specific applications, since the insertion and extraction body 1312 forms a groove 13122, the first limiting member 134 is connected to one side of the lock cylinder 132, the second limiting member 135 is connected to the insertion and extraction body 1312, and the elastic member abuts between the first limiting member 134 and the second limiting member 135. In this way, when the lock cylinder 132 moves relative to the insertion and extraction body 1312, the elastic member between the first limiting member 134 and the second limiting member 135 will undergo elastic deformation. When the handle 122 is released, the lock cylinder 132 is reset under the action of the elastic member.
[0041] In one possible implementation, the locking body 1311 is located between the handle 122 and the limiting sleeve 121. When the plug-in member 131 is rotated, and the pin 133 engages with the handle 122 and the handle 122 moves toward the limiting sleeve 121, the locking body 1311 engages with the first limiting groove 1221, so that the plug-in member 131 is inserted into the limiting hole 141 for locking. When the pin 133 is movably connected to the handle 122 and the handle 122 moves toward the limiting sleeve 121, the locking body 1311 engages with the second limiting groove 1222, so that the plug-in member 131 is movably connected to the limiting hole 141. In practical applications, the handle 122 has a first limiting groove 1221 and a second limiting groove 1222 with a rotational misalignment. One end of the insertion / removal component 131 is provided with a locking body 1311, which is located between the handle 122 and the limiting sleeve 121. When the insertion / removal component 131 rotates a certain angle relative to the handle 122 and reaches its final position, the pin 133 elastically engages the handle 122, moving the handle 122 toward the limiting sleeve 121. At this time, the locking body 1311 engages with the first limiting groove 1221, and the lock cylinder 132 moves with the pin 133 to release the constraint on the insertion / removal component 131, thereby allowing the handle 122 to drive the insertion / removal component 1221. 31. The transmission is inserted into the limiting hole 141 for locking; when the pin 133 is movably connected to the handle 122, that is, the pin 133 cannot be locked to the handle 122, and the handle 122 moves toward the limiting sleeve 121, the locking body 1311 can be locked into the second limiting groove 1222, so that the insertion and removal part 131 is movably connected to the limiting hole 141 and cannot be locked. At this time, the angle between the clamping part 110 and the connecting seat 140 can be adjusted by the insertion and removal part 131, so that the insertion and removal part 131 can be flexibly and conveniently adjusted relative to the connecting seat 140, thereby improving the convenience of disassembly and assembly and the flexibility of adjustment during the use of the lifting lock structure 100.
[0042] In one possible implementation, a first through hole 1223 is formed on the handle 122 perpendicular to the first limiting groove 1221. When the plug-in member 131 rotates to the position where the locking body 1311 is directly opposite the first limiting groove 1221, the pin 133 is elastically inserted into the first through hole 1223 so that the pin 133 is engaged with the handle 122. In practical applications, since the first limiting groove 1221 and the second limiting groove 1222 are square grooves that are staggered, the first through hole 1223 is formed on the handle 122 perpendicular to the first limiting groove 1221. When the plug-in member 131 rotates relative to the handle 122, the pin 133 will only be elastically engaged in the first through hole 1223 when the plug-in member 131 rotates to the position where the locking body 1311 is directly opposite the first limiting groove 1221. This allows the pin 133 to be engaged with the handle 122. Since the pin 133 is connected to the lock cylinder 132, when the handle 122 moves the pin 133 toward the limiting sleeve 121, the pin 133 also moves the lock cylinder 132 toward the limiting sleeve 121. This allows the lock cylinder 132 to release the constraint on the plug-in member 131, improving the safety of the lifting lock structure 100.
[0043] In one possible implementation, the handle 122 also has an annular guide groove 1224, a first through hole 1223 located in the annular guide groove 1224, and a pin 133 movable within the annular guide groove 1224. In specific applications, to improve the smoothness of rotation of the plug 131 relative to the handle 122, an annular guide groove 1224 is formed on the inner wall of the handle 122. The first through hole 1223 is located in the annular guide groove 1224, and the pin 133 is movable within the annular guide groove 1224. This allows the pin 133 to be accurately positioned within the first through hole 1223. Furthermore, by simply improving the surface finish of the annular guide groove 1224, the resistance of the pin 133 in the handle 122 can be reduced, thereby improving the smoothness of rotation of the plug 131 relative to the handle 122 and reducing the manufacturing cost of the handle 122.
[0044] In one possible implementation, the clamping member 110 is provided with a ball bearing 112, and the insertion / removal member 131 further includes a second rotating shaft 1315. The second rotating shaft 1315 is connected to the end of the clamping body 1311 away from the insertion / removal member 1312. The end of the second rotating shaft 1315 forms a plurality of positioning grooves 13151. The ball bearing 112 moves in each positioning groove 13151, and the second rotating shaft 1315 rotates relative to the limiting sleeve 121. In specific applications, in order to improve the accuracy and smoothness of the rotation angle of the plug-in component 131 relative to the clamping component 110, a second rotating shaft 1315 is connected to the end of the clamping body 1311 away from the plug-in component 1312. The end of the second rotating shaft 1315 forms multiple positioning grooves 13151, and the ball bearing 112 moves in each positioning groove 13151. The second rotating shaft 1315 rotates relative to the limiting sleeve 121, so that the rotation angle of the plug-in component 131 is determined by the position of the ball bearing and the positioning groove 13151, and the contact area of the ball bearing 112 in the positioning groove 13151 is reduced, thereby improving the smoothness of the rotation of the plug-in component 131.
[0045] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
