Description

Technical Field

[0001] The present application relates to the technical field of winding equipment, and in particular to an easily detachable locking device for a sheet material belt receiving tray. Background Art

[0002] In continuous production equipment for sheet materials like metal foil and plastic foil, the sheet's reel must be mounted on the motor drive shaft. Driven by the motor, the reel rotates, thereby winding the sheet. Because the reel needs to be easily replaceable, quick installation and locking between the reel and the motor drive shaft are crucial for ensuring winding efficiency and finished product quality.

[0003] Currently, the existing technology often uses a screw-tightening method to secure the reel and motor drive shaft. This involves installing a screw on the reel, which is threadedly connected to the reel. By turning the screw, one end of the screw presses against the motor drive shaft, thereby securing the reel and motor. To replace the reel, simply loosen the screw to separate it from the motor drive shaft. The reel can then be removed from the motor drive shaft, effectively disassembling it.

[0004] Since the screw-tightening fixation only contacts the surface of the motor drive shaft through a single point at the end of the screw, the screw is subjected to greater force. After long-term use, the screw may become loose or strip, which in turn causes the receiving tray to shift, affecting the neatness of the receiving material and even causing safety problems. Summary of the Invention

[0005] The present application provides an easily detachable locking device for a sheet material belt receiving tray, the purpose of which is to improve the convenience of installation of the receiving tray and the motor drive shaft and the stability of the locking, while facilitating the disassembly and replacement of the receiving tray, improving the stability of the receiving tray during operation, and ensuring the neatness and safety of the sheet material belt receiving tray.

[0006] The present application provides an easily detachable locking device for a sheet material receiving tray, which adopts the following technical solutions: A sheet material strip receiving tray easily detachable locker, comprising a mounting plate for being mounted on the receiving tray, the mounting plate being provided with a clearance hole; a support ring, the support ring being arranged on the mounting plate, the clearance hole being coaxially arranged with the support ring; a locking block, the locking block being arranged on the support ring, and the locking block being slidingly connected to the support ring along the corresponding radial direction of the support ring; an arc-shaped slot being provided on the locking block facing the side of the clearance hole, the arc-shaped slot passing through the locking block axially along the support ring; a manual drive component, the manual drive component being arranged on the support ring, and the manual drive component being connected to the locking block, and the manual drive component being used to drive the locking block to slide on the support ring.

[0007] By adopting the above technical solution, the mounting plate is used to secure the locker to the receiving tray. The support ring and the clearance hole on the mounting plate are coaxially arranged to provide support for the motor drive shaft. The locking block can move radially along the support ring through a sliding connection. The arc-shaped slot on the locking block is designed to engage with the motor drive shaft to achieve the locking function. The manual drive member is connected to the locking block. By operating the manual drive member, the locking block can be driven to slide on the support ring, so that the arc-shaped slot and the drive shaft are tightly fitted, thereby achieving the locking function of the motor drive shaft.

[0008] The arc-shaped slot on the locking block allows the inner wall of the slot to fit tightly against the drive shaft, thereby increasing the contact area between the locking block and the drive shaft. This allows the locking block to withstand greater torque, thereby improving locking stability. Furthermore, the manual drive element allows the locking device to be assembled and disassembled without the need for additional tools, making it easier to assemble and disassemble the locking device and, in turn, to replace the receiving tray.

[0009] Therefore, the structural design based on the manual drive part and the locking block can improve the convenience of installation of the winding disk and the motor drive shaft and the stability of the locking. While facilitating the disassembly and replacement of the winding disk, it can also improve the stability of the material receiving disk during operation and ensure the neatness and safety of the sheet tape winding.

[0010] Optionally, the manual drive component includes a fixed plate, which is connected to the outer wall of the support ring and is spaced apart from the locking block along the sliding direction of the locking block; a driving stud is provided between the fixed plate and the locking block, one end of the driving stud is rotatably connected to the fixed plate, and the other end is threadedly connected to the locking block; a driving handle is provided on the side of the fixed plate away from the locking block, and the driving handle is coaxially connected to the driving stud.

[0011] By adopting the above technical solution, the manual drive component realizes the stable installation of the drive stud through the setting of the fixed plate, and since one end of the drive stud is screwed to the locking block, when the drive stud is rotated, the locking block can be driven to slide along the corresponding radial direction of the support ring, which can realize the locking or loosening of the motor drive shaft by the locking block.

[0012] The manual drive member is provided with a drive handle, and the drive handle is coaxially connected to the drive stud, which facilitates manual rotation of the drive stud, simplifies the locking and unlocking operation process, and improves the convenience of using the locker.

[0013] Optionally, a plurality of the locking blocks, the fixing plates and the driving studs are provided, and the locking blocks, the fixing plates and the driving studs are arranged in one-to-one correspondence, one end of the driving stud is threadedly connected to the corresponding locking block, and the other end is rotatably connected to the corresponding fixing plate; a plurality of the locking blocks are arranged in sequence at intervals along the circumference of the support ring, and the driving handle is detachably connected to the driving stud.

[0014] By adopting the above technical solution, first, a number of locking blocks are arranged in sequence along the circumference of the support ring, and cooperate with the corresponding fixing plates and drive studs. This enables the locker to lock the motor drive shaft at multiple points, significantly improving the locking stability.

[0015] Secondly, since the driving handle is detachably connected to the driving stud, a single driving handle can be connected to all the driving studs in sequence, thereby driving all the locking blocks to lock the motor drive shaft, which can reduce the number of driving handles required and reduce the space occupied by the locker.

[0016] At the same time, the design of the detachable connection between the driving handle and the driving stud allows the driving handle to be removed after the locking operation is completed, thereby reducing the space occupied by the locker.

[0017] Optionally, a quick-connect assembly is provided on the driving handle, and the quick-connect assembly includes a square rod, which is coaxially connected to the driving handle. A square hole is provided at one end of the driving stud axially away from the corresponding locking block, and the square rod is plugged into the corresponding square hole.

[0018] By adopting the above technical solution, the quick-connect assembly makes the connection between the driving handle and the driving stud more convenient. Specifically, the square rod and the square hole fit together, so that when the driving handle rotates, the driving stud rotates coaxially. This enables the driving handle and the driving stud to be quickly connected, thereby improving the efficiency of the locking device in actual operation.

[0019] Optionally, the quick-connect assembly further includes a movable plate and a plug-in column, one end of the plug-in column is coaxially fixedly connected to the square rod, and the other end is fixedly connected to the driving handle, and the plug-in column is rotatably connected to the movable plate, and the movable plate is detachably connected to the fixed plate.

[0020] By adopting the above technical solution, since the movable plate and the fixed plate are detachably connected, the plug-in column and the movable plate are rotatably connected, and the plug-in column is fixedly connected to the driving handle, and the square rod and the plug-in column are coaxially connected, after the movable plate and the corresponding fixed plate are installed, the square rod is automatically inserted into the square hole of the corresponding driving stud, and the connection between the driving handle and the corresponding driving stud is automatically established, which can improve the stability of the installation of the driving handle.

[0021] Optionally, the driving handle includes a rotating seat and an extension handle, the rotating seat is coaxially rotatably connected to the driving stud, and one end of the extension handle in the length direction is rotatably connected to the rotating seat.

[0022] By adopting the above technical solution, the rotating seat and the drive stud are coaxially connected, allowing the rotating seat to transmit rotational force to the drive stud, thereby driving the locking block. The provision of an extension handle facilitates gripping the extension handle to drive the rotating seat, and the rotatable connection between the extension handle and the rotating seat allows the position of the extension handle to be flexibly adjusted according to the actual operating space, improving operational convenience while avoiding the inconvenience of driving caused by limited operating space.

[0023] Optionally, a handle seat is further included, which is detachably connected to the support ring, and the handle seat and the rotating seat are axially spaced apart from each other along the support ring; a handle groove is provided on the handle seat, and the extended handle is engaged with the handle groove.

[0024] By adopting the above technical solution, the handle seat is detachably connected to the support ring, and a handle slot is provided on the handle seat. The extension handle can be engaged with the handle slot. When the extension handle is not needed, the extension handle can be rotated to be inserted into the handle slot, thereby fixing the extension handle, preventing the extension handle from swinging or being lost at will, and avoiding the extension handle from interfering with other equipment or structures, thereby improving the neatness and safety of the overall device.

[0025] Optionally, the support ring is rotatably connected to the mounting plate.

[0026] The aforementioned technical solution allows the support ring to be angularly adjusted relative to the mounting plate thanks to its pivoting connection to the mounting plate. This structure allows the user to adjust the support ring's angle as needed, optimizing the alignment and locking operation of the locking block and the motor drive shaft. Furthermore, the manual actuator can be adjusted by rotating the support ring, increasing its positional flexibility and preventing interference from other components or structures.

[0027] Optionally, a rotation locking assembly is provided between the support ring and the mounting plate, and the rotation locking assembly is used to lock the support ring and the mounting plate.

[0028] By adopting this technical solution, the rotation locking assembly effectively locks the relative position between the support ring and the mounting plate, ensuring that the support ring's angle remains fixed during operation. This design improves the stability and reliability of the locking device in practical applications and prevents locking failure caused by accidental rotation of the support ring.

[0029] In summary, this application includes at least one of the following beneficial technical effects: 1. This application improves the convenience of installing the winding reel and the motor drive shaft and the stability of the locking through the structural design of the manual drive part and the locking block. While facilitating the disassembly and replacement of the winding reel, it improves the stability of the material receiving reel during operation and ensures the neatness and safety of the sheet material strip winding.

[0045] The following is combined with Figure 1 -Attached Figure 12 , further details of this application are given.

[0046] Example 1: A sheet material with a receiving tray that is easily removable and locks the material. Figure 1 and Figure 2 , including a mounting plate 1, a support ring 2, a locking block 3 and a manual drive member 4. A clearance hole 11 is provided on the mounting plate 1, the support ring 2 is arranged on the mounting plate 1, and the support ring 2 is coaxially arranged with the clearance hole 11, the locking block 3 is arranged on the support ring 2, and the locking block 3 is slidingly connected to the support ring 2 along the corresponding radial direction of the support ring 2, and an arc-shaped groove 31 is provided on the side of the locking block 3 facing the clearance hole 11, and the arc-shaped groove 31 passes through the locking block 3 along the axial direction of the support ring 2, the manual drive member 4 is provided on the support ring 2, and the manual drive member 4 is connected to the locking block 3.

[0047] After the mounting plate 1 is mounted on the receiving tray, the motor drive shaft engages with the clearance hole 11. The manual drive member 4 then drives the locking block 3 toward the drive shaft until the drive shaft engages with the arc-shaped slot 31. At this point, the inner wall of the arc-shaped slot 31 contacts the drive shaft, and the locking block 3 locks the drive shaft. The arc-shaped slot 31 increases the contact area between the locking block 3 and the drive shaft, allowing the locking block 3 to withstand greater torque without loosening, thereby improving the stability of the locking between the receiving tray and the motor.

[0048] Reference Figure 1 Two jacks 12 are provided on the mounting plate 1 , and the two jacks 12 are spaced apart along the length direction of the mounting plate 1 , and the clearance hole 11 is located between the two jacks 12 along the length direction of the mounting plate 1 .

[0049] Due to the opening of the sockets 12, when the locking device is installed on the receiving tray, both sockets 12 are plugged into the corresponding bosses on the receiving tray. The locking device locks the motor drive shaft through the locking block 3 and the manual drive member 4. In this case, no additional fixing is required. When the motor drive shaft rotates, the receiving tray rotates synchronously with the cooperation of the mounting plate 1 and the bosses on the receiving tray. Therefore, this structural arrangement facilitates the installation and removal of the locking device.

[0050] Reference Figure 1 and Figure 2 A guide slot 21 is defined on the inner sidewall of the support ring 2. The depth of the guide slot 21 extends radially along the support ring 2 and extends through the support ring 2 along its depth. The locking block 3 engages with the guide slot 21 and slides along the inner sidewall of the slot 21 along its depth. The guide slot 21 facilitates a sliding connection between the locking block 3 and the support ring 2 and also provides guidance for the locking block 3.

[0051] Reference Figure 1 and Figure 2 The manual drive member 4 includes a fixing plate 41, a driving stud 42, and a driving handle 43. The fixing plate 41 is disposed outside the support ring 2 and is bolted to the support ring 2. The fixing plate 41 closes the guide slot 21. The driving stud 42 is located within the guide slot 21 and is axially arranged along the depth direction of the guide slot 21. One end of the driving stud 42 is threadedly connected to the locking block 3, and the other end is rotationally connected to the fixing plate 41. The driving handle 43 is located on the side of the fixing plate 41 facing away from the locking block 3 and is coaxially connected to the driving stud 42. The driving handle 43 is rotationally connected to the fixing plate 41 or spaced apart.

[0052] When the driving handle 43 is rotated, the driving stud 42 rotates coaxially. Under the guidance of the guide slot 21 and the effect of limiting rotation, the driving stud 42 and the locking block 3 are opposite each other. Since the driving stud 42 and the locking block 3 are screwed together, the driving stud 42 and the locking block 3 can move relative to each other along the depth direction of the guide slot 21. On this basis, since one end of the driving stud 42 is connected to the fixing plate 41, the position of the driving stud 42 is fixed, which allows the locking block 3 to move along the depth direction of the guide slot 21, thus satisfying the function of the manual driving member 4.

[0053] Reference Figure 1 and Figure 2In this embodiment, the driving handle 43 includes a rotating base 431 and an extension handle 432. The rotating base 431 is coaxially connected to the driving stud 42, and one end of the extension handle 432 is rotatably connected to the rotating base 431 along its length. Since the extension handle 432 is rotatably connected to the rotating base 431, the position of the extension handle 432 can be flexibly adjusted, thereby allowing the position of the extension handle 432 to meet the requirements of different installation spaces where the lock is located, thereby ensuring the normal operation of the driving handle 433.

[0054] The implementation principle of the embodiment of the present application is: after the locker is installed to one end of the receiving tray, the motor drive shaft passes through the clearance hole 11 and the support ring 2 in sequence, and then the extension handle 432 is rotated. At this time, the driving stud 42 rotates, which causes the locking block 3 to move in the direction of the motor drive shaft until the motor drive shaft conflicts with the inner wall of the arc-shaped slot 31 of the locking block 3.

[0055] When the receiving tray needs to be replaced, the extension handle 432 is rotated in the opposite direction, and the locking block 3 is separated from the motor drive shaft. At this time, the receiving tray and the locker can be removed from the motor drive shaft.

[0056] Because the locking block 3 abuts the motor drive shaft, the inner sidewall of the arc-shaped slot 31 fits the drive shaft, which increases the contact area between the locking block 3 and the drive shaft. This allows the locking block 3 to withstand large torques without loosening, thereby improving the stability of the locking between the receiving tray and the motor. The structure of the manual drive member 4 allows the receiving tray to be installed and removed without the need for additional tools, which improves the convenience of using the lock.

[0057] Example 2: A sheet material with a receiving tray that is easily removable and lockable, see Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that: a plurality of locking blocks 3 are provided, the plurality of locking blocks 3 are arranged in sequence along the circumference of the support ring 2, and the plurality of locking blocks 3 are arranged in a ring shape.

[0058] Reference Figure 4 and Figure 5 There are several guide grooves 21 on the support ring 2, and the guide grooves 21 are arranged in sequence along the circumference of the support ring 2, and the depth direction of the guide grooves 21 is arranged along the corresponding radial direction of the support ring 2.

[0059] Reference Figure 4 and Figure 5 The locking block 3 is arranged in a one-to-one correspondence with the guide slot 21, and the locking block 3 is inserted into the corresponding guide slot 21, and the locking block 3 is slidably connected to the inner side wall of the corresponding guide slot 21 along the depth direction of the corresponding guide slot 21.

[0060] Reference Figure 4 and Figure 5 There are several fixing plates 41 and driving studs 42, and the fixing plates 41 and driving studs 42 are arranged one by one in correspondence with the locking blocks 3. The fixing plate 41 is located outside the support ring 2, and the fixing plate 41 closes the corresponding guide slot 21. The driving stud 42 is located in the corresponding guide slot 21. One end of the driving stud 42 is rotatably connected to the corresponding fixing plate 41, and the other end is screwed to the corresponding locking block 3.

[0061] Based on the coordinated arrangement of the locking blocks 3, the fixing plates 41 and the driving studs 42, the locking blocks 3 can be used to lock the motor drive shaft, which can achieve multi-point locking and thus improve the locking stability.

[0062] Reference Figure 4 and Figure 5 The drive handle 43 is coaxially and detachably connected to the drive stud 42. This allows the drive handle 43 to be installed on all the drive studs 42 in sequence, thereby driving multiple locking blocks 3 to lock the motor drive shaft in sequence. Furthermore, after the multiple locking blocks 3 have been driven, the drive handle 43 can be removed from the support ring 2, thus reducing the space occupied by the locking device.

[0063] Reference Figure 4 and Figure 5 A quick-connect assembly 44 is provided between the driving handle 43 and the driving stud 42 . The quick-connect assembly 44 includes a movable plate 441 . The movable plate 441 is detachably connected to the fixed plate 41 .

[0064] Reference Figure 4 and Figure 6 The quick-connect assembly 44 also includes a plug-in column 442, which is axially arranged along the thickness direction of the movable plate 441. The plug-in column 442 is rotatably connected to the movable plate 441, and one end of the plug-in column 442 is coaxially connected to the rotating seat 431, and the lower end of the plug-in column 442 is coaxially connected to the square rod 443.

[0065] Reference Figure 4 and Figure 6 A square hole 421 is formed at one end of the driving stud 42 away from the corresponding locking block 3 along its own axial direction, and when the movable plate 441 is connected to the fixed plate 41, the square rod 443 is plugged into the corresponding square hole 421.

[0066] Based on the matching setting between the square rod 443 and the square hole 421, after the driving handle 43 is installed on the corresponding fixed plate 41 through the quick-connect assembly 44, the square rod 443 is plugged into the square hole 421. At this time, when the rotating seat 431 is driven to rotate by the driving handle 43, the square rod 443 rotates synchronously under the action of the plug-in column 442. At this time, since the cross-sections of the square rod 443 and the square hole 421 are both square, the square rod 443 will drive the corresponding driving stud 42 to rotate, thereby realizing the function of the manual driving part 4.

[0067] Reference Figure 5 and Figure 6 In this embodiment, the movable plate 441 is connected to the fixed plate 41 by a knurled hand-tightening bolt. Since the knurled hand-tightening bolt can be manually installed and removed, the convenience of installing and removing the driving handle 43 and the fixed plate 41 can be improved.

[0068] Reference Figure 3 and Figure 7 An angle adjustment mechanism 5 is provided between the mounting plate 1 and the support ring 2 , and the angle adjustment mechanism 5 includes a rotating mounting assembly 51 , a rotating connecting assembly 52 and a rotating locking assembly 53 .

[0069] Reference Figure 3 and Figure 7 The rotatable mounting assembly 51 is mounted on the mounting plate 1 and includes a mounting tube 511 and a mounting ring 512. The mounting ring 512 is coaxially disposed with the support ring 2, and the mounting plate 1 and the mounting ring 512 are coaxially spaced apart. The mounting tube 511 is coaxially disposed with the support ring 2 and is axially located between the mounting plate 1 and the support ring 2. One end of the mounting tube 511 is detachably connected to the mounting plate 1, and the other end is fixedly connected to the support ring 2.

[0070] Reference Figure 3 and Figure 7 The rotating connection component 52 is arranged on the support ring 2. The rotating connection component 52 includes a lifting ring 521 and a rotating ring 522. The lifting ring 521 is coaxially arranged with the support ring 2, and the lifting ring 521 is located between the support ring 2 and the mounting plate 1 along its own axis. One end of the lifting ring 521 is detachably connected to the support ring 2, and the other end is coaxially inserted in the rotating ring 522, and the rotating ring 522 is coaxially detachably connected to the lifting ring 521.

[0071] Reference Figure 7 and Figure 8 The rotating ring 522 is plugged into the mounting tube 511 and is located axially between the mounting ring 512 and the mounting plate 1. The rotating ring 522 is rotatably connected to the mounting tube 511. The lifting ring 521 is plugged into the mounting ring 512, and the outer wall of the lifting ring 521 is spaced apart from the inner wall of the mounting ring 512.

[0072] Based on the setting of the rotating connection component 52 and the rotating installation component 51, a rotating connection is achieved between the support ring 2 and the mounting plate 1, which enables the support ring 2 to be rotated to adjust the angle of the support ring 2, thereby facilitating the disassembly and rotation of the driving handle 43, and also facilitating the driving of the locking block 3.

[0073] Reference Figure 3 and Figure 7 The rotation locking assembly 53 includes a plurality of positioning bolts 531. The rotating ring 522 is provided with a plurality of first holes 532, which are spaced apart along the circumference of the rotating ring 522. The mounting ring 512 is provided with a plurality of second holes 533, with the first holes 532 corresponding to the second holes 533 and communicating with the corresponding second holes 533. A plurality of positioning bolts 531 are provided between the rotating ring 522 and the mounting ring 512, with the plurality of first holes 532 corresponding to the positioning bolts 531. The positioning bolts 531 engage with the corresponding first holes 532 and second holes 533.

[0074] The positioning bolts 531 are provided to relatively lock the rotating ring 522 and the mounting ring 512. Therefore, after removing the positioning bolts 531, the support ring 2 can be rotated to adjust the angle. After installing the positioning bolts 531, the rotating plate and the mounting ring 512 are fixed by the positioning bolts 531, thus securing the support ring 2 and ensuring its stability during operation.

[0075] Reference Figure 3 and Figure 7 The locking device also includes a fixed handle assembly 6, which includes an assembly ring 61. The assembly ring 61 is coaxially arranged with the support ring 2. The assembly ring 61 is located on the side of the support ring 2 away from the mounting plate 1 along its own axial direction, and the assembly ring 61 is detachably connected to the support ring 2.

[0076] Reference Figure 3 and Figure 7 The outer wall of the assembly ring 61 is provided with a plurality of mounting surfaces 611 , which are spaced apart in sequence along the circumference of the assembly ring 61 , and the mounting surfaces 611 are arranged in one-to-one correspondence with the fixing plates 41 , and the mounting surfaces 611 and the corresponding fixing plates 41 are spaced apart in the axial direction of the assembly ring 61 .

[0077] Reference Figure 3 and Figure 7The fixed handle assembly 6 includes a handle seat 62, which is disposed outside the assembly ring 61. The handle seat 62 and the driving handle 43 are spaced apart along the axial direction of the assembly ring 61. The handle seat 62 is disposed on a corresponding mounting surface 611 and is detachably connected to the mounting surface 611. A handle groove 621 is defined on the upper side of the handle seat 62. The handle groove 621 extends through the handle seat 62 along the axial direction of the assembly ring 61, and the extended handle 432 is engaged with the handle groove 621.

[0078] After using the driving handle 43, the extension handle 432 is rotated until it is locked in the handle groove 621, so that when the extension handle 432 needs to stay on the support ring 2, the handle seat 62 fixes the extension handle 432 to prevent the extension handle 432 from moving, thereby preventing the extension handle 432 from interfering with other equipment or structures.

[0079] Reference Figure 3 and Figure 7 In this embodiment, the handle seat 62 is connected to the corresponding mounting surface 611 by a knurled hand-lift bolt, which facilitates the disassembly and assembly of the handle seat 62 and also facilitates the adjustment of the position of the handle seat 62 following the driving handle 43.

[0080] Reference Figure 3 and Figure 7 In this embodiment, a plurality of mounting rods 612 are provided on the outer wall of the assembly ring 61. The mounting rods 612 are fixedly connected to the outer wall of the assembly ring 61. The length direction of the mounting rods 612 is arranged axially along the assembly ring 61. The plurality of mounting rods 612 are arranged in sequence along the circumference of the assembly ring 61.

[0081] Reference Figure 3 and Figure 7 The mounting rods 612 are located outside the support ring 2 and are slidably connected to the outer wall of the support ring 2 along their length. A clearance groove 613 is provided between two adjacent mounting rods 612. The clearance grooves 613 are provided in a one-to-one correspondence with the fixing plates 41, and the fixing plates 41 are located in the corresponding clearance grooves 613.

[0082] Reference Figure 3 and Figure 7 One end of the mounting rod 612 along its own length direction abuts against the mounting ring 512 , the positioning bolts 531 and the mounting rods 612 are arranged in a one-to-one correspondence, and the positioning bolts 531 are threadedly connected to the corresponding mounting rods 612 .

[0083] Reference Figure 3 and Figure 7 Based on the coordinated arrangement of the mounting rod 612, the positioning bolt 531, the rotating connection assembly 52 and the rotating mounting assembly 51, the assembly ring 61, the support ring 2 and the mounting plate 1 are connected as a whole, thereby realizing the detachability of the locker and increasing the stability of the locker structure.

[0084] The implementation principle of the embodiment of the present application is: when locking the motor drive shaft, remove all positioning bolts 531. At this time, the support ring 2 can be rotated to ensure that the required position of the fixing plate 41 on the support ring 2 is convenient for installing the drive handle 43, and then reinstall the positioning bolts 531.

[0085] Then, the driving handles 43 are assembled on the required fixing plates 41 in sequence, and the driving handles 43 are rotated to press the corresponding locking blocks 3 against the motor driving shaft.

[0086] Finally, when the driving handle 43 needs to be removed, it can be directly removed from the corresponding fixing plate 41. When the driving handle 43 needs to be retained, the assembly ring 61 is mounted to the support ring 2 using the positioning bolts 531, and then the clamping handle seat 62 is installed on the corresponding mounting surface 611 of the assembly ring 61. Finally, the extension handle 432 is rotated until it is locked into the clamping handle groove 621, at which point the extension handle 432 is locked.

[0087] Example 3: A sheet material with a receiving tray that is easily removable and locks the material. Figure 1 The difference between this embodiment and embodiment 2 is that: Reference Figure 9 and Figure 10 The outer wall of the support ring 2 is provided with a plurality of floating grooves 22 , and the floating grooves 22 are arranged in a one-to-one correspondence with the guide grooves 21 , and the guide grooves 21 are provided at the bottom of the floating grooves 22 .

[0088] Reference Figure 10 and Figure 11 The fixed plate 41 and the floating groove 22 are arranged in a one-to-one correspondence, the fixed plate 41 is plugged into the corresponding floating groove 22, and the fixed plate 41 is slidably connected to the corresponding floating groove 22 along the depth direction of the corresponding floating groove 22.

[0089] Reference Figure 11 A number of support springs 411 are provided at the bottom of the fixed plate 41 and the corresponding floating groove 22. The length direction of the support spring 411 is arranged along the depth direction of the floating groove 22. One end of the support spring 411 is connected to the fixed plate 41, and the other end is connected to the bottom of the corresponding floating groove 22.

[0090] Such a structural design enables the fixing plate 41 to float in the floating groove 22 , thereby making the position of the fixing plate 41 adjustable, and also making the position of the driving stud 42 and the correspondingly connected locking block 3 adjustable.

[0091] Reference Figure 10 and Figure 11In this embodiment, a plurality of guide bolts 412 are disposed between the fixed plate 41 and the support ring 2. The guide bolts 412 are positioned within corresponding floating grooves 22, with the axial direction of the guide bolts 412 extending along the depth of the corresponding floating grooves 22. The guide bolts 412 are threadedly engaged with the bottom of the corresponding floating grooves 22. The guide bolts 412 pass through the corresponding fixed plate 41 and are slidably coupled to the fixed plate 41 along the axial direction of the guide bolts 412. The guide bolts 412 are disposed in a one-to-one correspondence with the support springs 411, which are sleeved around the outer sides of the corresponding guide bolts 412.

[0092] The setting of the guide bolt 412 has a guiding effect on the floating of the fixed plate 41 in the corresponding floating groove 22. At the same time, the nut of the guide bolt 412 has a limiting effect on the fixed plate 41, which can effectively improve the installation and floating stability of the fixed plate 41.

[0093] Reference Figure 9 and Figure 10 The movable plate 441 is detachably connected to the support ring 2. A fixed plate 41 is disposed opposite the movable plate 441. The movable plate 441 and the corresponding fixed plate 41 are spaced apart axially along the guide bolt 412, and the nut of the guide bolt 412 is located between the movable plate 441 and the corresponding fixed plate 41. In this embodiment, the movable plate 441 is connected to the support plate by bolts.

[0094] Based on the arrangement of the movable plate 441, after the movable plate 441 is mounted on the support ring 2, the square rod 443 automatically inserts into the square hole 421 of the corresponding drive stud 42. At this time, rotating the drive handle 43 rotates the corresponding drive stud 42, thereby driving the stud 42 and the corresponding locking block 3 to rotate relative to each other. At this time, due to the constraints of the support spring 411 and the nut of the guide bolt 412, the position of the fixed plate 41 remains unchanged. Therefore, the rotation of the drive stud 42 causes the locking block 3 to move, thus ensuring that the locking block 3 can be driven normally.

[0095] Reference Figure 9 and Figure 12 A synchronous motion component 7 is also provided on the support ring 2 , and the synchronous motion component 7 is located on the side of the support ring 2 facing the mounting plate 1 .

[0096] Reference Figure 11 and Figure 12 The synchronous motion assembly 7 includes a ring gear 71, several gears 72, and several racks 73. The ring gear 71 is coaxially rotatably connected to the support ring 2. The racks 73 are provided in a one-to-one correspondence with the locking blocks 3. The racks 73 are connected to the locking blocks 3, and the length of the racks 73 is arranged along the movement direction of the corresponding locking blocks 3. The gears 72 are provided in a one-to-one correspondence with the racks 73. The gears 72 are rotatably connected to the support ring 2, and the gears 72 mesh with the corresponding racks 73. The gears 72 mesh with the ring gear 71.

[0097] When one locking block 3 moves, the corresponding rack 73 drives the corresponding gear 72 to rotate, which in turn drives the ring gear 71 to rotate synchronously. At this time, the ring gear 71 drives all gears 72 to rotate, which in turn drives all racks 73 to move along its own length. This structural arrangement ensures that when a single locking block 3 moves, all other locking blocks 3 move synchronously, which can improve the convenience of locking the motor drive shaft of the locker.

[0098] The implementation principle of the embodiment of the present application is: when locking the motor drive shaft, select any locking block 3 and install the movable plate 441 to the corresponding position. At this time, the square rod 443 is plugged into the corresponding square hole 421, and the driving handle 43 is connected to the corresponding driving stud 42. At this time, rotate the driving handle 43, and the corresponding driving stud 42 rotates, thereby moving the corresponding locking block 3.

[0099] When the corresponding locking block 3 moves, under the transmission action of the ring gear 71, several gears 72 and several racks 73, all locking blocks 3 move synchronously, and the locking block 3 drives the corresponding fixing plate 41 to float in the corresponding floating groove 22 through the driving stud 42.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
