Description

Technical Field

[0001] This invention relates to the field of disc centrifuge technology, and more specifically, to a disc centrifuge housing locking installation structure that facilitates positioning. Background Technology

[0002] In current disc centrifuge equipment, the connection between the outer casing of the drum and the lower part of the casing generally follows the ISO4762 standard and is fastened with stainless steel hexagonal head screws. In industry practice, the commonly used screw specifications are M8-M12, and the torque requirement is in the range of 35-80 N·m.

[0003] Currently, maintenance of existing disc centrifuges requires the removal and installation of as many as 8-24 M8-M12 screws, taking 10-20 minutes and accounting for about 10% of the total maintenance time. This significantly reduces maintenance efficiency, especially in scenarios where rapid equipment recovery is urgently needed. Furthermore, disassembled screws are easily lost, potentially falling onto other equipment and causing collateral damage or serious safety accidents. In addition, manual screw tightening exhibits torque variation, with preload deviations reaching ±30%, affecting connection tightness and sealing, potentially leading to material leakage and production interruptions. For compact disc centrifuges, the limited space for screw installation creates interference issues during disassembly and assembly, easily causing tools to slip and damage equipment or personnel. Therefore, we propose a locking installation structure for the disc centrifuge casing that facilitates easy positioning. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a locking installation structure for a disc centrifuge casing that is easy to position, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a locking installation structure for a disc centrifuge housing that is easy to position, comprising a housing device and a lower housing device, wherein a connecting frame is slidably connected to the outer side of the lower housing device, and a plurality of locking assemblies are provided between the housing device and the connecting frame.

[0006] The locking assembly includes a mounting rod installed on the outside of the cover device and a pin rod installed on the top of the connecting frame. A pin plate is installed on one side of the mounting rod. The pin plate has a storage groove and two symmetrical guide grooves and positioning grooves inside. A groove is opened inside the pin rod. A spring is connected inside the groove. A slide is installed at one end of the spring. A guide plate is installed at one end of the slide. A drive plate is installed at one end of the guide plate. Lifting plates are slidably connected to both sides of the guide plate. A slot is opened inside the lifting plate. Several sets of springs are installed inside the slot. A pressing block is installed at one end of each spring. Two symmetrical through grooves are opened on the outside of the pin rod.

[0007] Preferably, two symmetrical connecting plates are installed on the inner side of the connecting frame, and two symmetrical connecting grooves are opened on the outer side of the lower part of the cover.

[0008] Preferably, the connecting plate is made of stainless steel, and a push-pull electromagnet is installed at the top of the interior of each of the two connecting slots.

[0009] Preferably, the connecting plate is slidably connected inside the connecting groove.

[0010] Preferably, the pin is located in the storage groove, the slide is slidably connected to the inside of the groove, the guide plate is triangular in shape, and one end of the pin has a groove corresponding to the drive plate.

[0011] Preferably, both sides of the guide plate are provided with sliding grooves, and sliding plates are slidably connected inside the two sliding grooves, with the sliding plates connected to the lifting plate.

[0012] Preferably, the lifting plates are located at the positions of the guide groove and the through groove, respectively, and the extrusion block is adapted to the positioning groove.

[0013] Preferably, the extrusion block is slidably connected inside the groove, and one side of the extrusion block is an inclined surface.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. When in use, this invention adopts a pin-type locking structure, which greatly reduces the cumbersome disassembly and assembly actions in traditional screw fastening methods, reduces operational redundancy, and significantly simplifies the operation steps. When performing maintenance work, operators no longer need to spend a lot of time disassembling and assembling screws one by one. They only need to drive the actuator (such as a push-pull electromagnet) to complete the insertion or release of the pin to lock or unlock the cover, which greatly shortens the maintenance time and improves maintenance efficiency.

[0016] 2. When using this invention, since it eliminates traditional screws and other loose fasteners, it avoids equipment damage accidents caused by screws falling out; at the same time, by optimizing the design of the locking mechanism, it ensures the stability of the cover during equipment operation, further improving the safety performance of the equipment.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] As attached Figures 1-8 The disc centrifuge housing locking installation structure shown includes a housing device 1 and a lower housing device 2. A connecting frame 3 is slidably connected to the outer side of the lower housing device 2. Several sets of locking components 4 are provided between the housing device 1 and the connecting frame 3. Two symmetrical connecting plates 5 are installed on the inner side of the connecting frame 3. Two symmetrical connecting grooves 6 are opened on the outer side of the lower housing device 2. The connecting plates 5 are made of stainless steel. Push-pull electromagnets 7 are installed at the top of the inner part of the two connecting grooves 6. The connecting plates 5 are slidably connected inside the connecting grooves 6.

[0028] The locking assembly 4 is provided with several sets, and the machine cover device 1 and the lower part of the machine cover device 2 can be quickly disassembled and assembled through the locking assembly 4;

[0029] The locking assembly 4 includes a mounting rod 41 installed on the outside of the cover device 1 and a pin rod 46 installed on the top of the connecting frame 3. A pin plate 42 is installed on one side of the mounting rod 41. The pin plate 42 has a storage groove 43 and two symmetrical guide grooves 44 and positioning grooves 45 inside. The pin rod 46 is located in the storage groove 43. A groove 47 is opened inside the pin rod 46. A spring 48 is connected inside the groove 47. A slide 49 is installed at one end of the spring 48. The slide 49 is slidably connected inside the groove 47. A guide plate 410 is installed at one end of the slide 49. The guide plate 410 is triangular in shape. A drive plate 411 is installed at one end of the guide plate 410. A corresponding drive plate is opened at one end of the pin rod 46. The guide plate 410 has two sliding grooves 412 on both sides of the groove 411. The sliding plate 413 is slidably connected inside the two sliding grooves 412. The sliding plate 413 is connected to the lifting plate 414. The guide plate 410 has two sliding plates 414 on both sides. The lifting plate 414 has a slot 415 inside. Several sets of springs 416 are installed inside the slot 415. One end of each spring 416 is fitted with a pressing block 417. The pressing block 417 is slidably connected inside the slot 415. One side of the pressing block 417 is a slope. The pressing block 417 is adapted to the positioning groove 45. The outer side of the pin rod 46 has two symmetrical through grooves 418. The lifting plate 414 is located at the guide groove 44 and the through groove 418 respectively.

[0030] The push-pull electromagnet 7 is installed in the lower part of the cover device 2, and the push-pull end is located in the connecting groove 6 for moving the connecting plate 5. When the cover device 1 and the lower part of the cover device 2 are in the unlocked state, the pressing block 417 and the lifting plate 414 are located in the groove 47, and the top of the lifting plate 414 is at the same level as the outer surface of the pin rod 46. The pressing block 417 is stored in the receiving groove 43 of the pin plate 42. The pressing block 417 is slidably connected to the inside of the slot 415, so that the pressing block 417 can move linearly.

[0031] When the cover device 1 and the lower cover device 2 are locked, the spring 48 is in a compressed state, and the push-pull electromagnet 7 is set so that the connecting plate 5 is at the uppermost end of the connecting groove 6; when the push-pull electromagnet 7 moves the connecting plate 5 to the lowest end of the connecting groove 6, the spring 48 is reset, and the device can be unlocked.

[0032] Working principle of the invention: When the cover device 1 and the lower cover device 2 need to be unlocked, the connecting frame 3 moves downward along the outside of the lower cover device 2 through the setting of several sets of push-pull electromagnets 7. As the connecting frame 3 moves, it drives the pin rod 46 to move. At this time, the spring 48 returns to its original position, and the drive plate 411 protrudes from one side of the pin rod 46. Since the guide plate 410 is triangular, during the pushing process, the lifting plate 414 moves towards the lower end of the guide plate 410 through the setting of the sliding plate 413 and the sliding groove 412. The lifting plate 414 gradually moves into the groove 47. At the same time, the pressure is applied. The inclined surface of block 417 is squeezed by the inner wall of positioning groove 45, causing the squeezing block 417 to move into the groove 415. At the same time, spring 416 is compressed. When the squeezing block 417 is completely separated from the positioning groove 45 and located in the groove 415, the top of the lifting plate 414 and the outer surface of the pin rod 46 are brought to the same horizontal plane by the movement of the guide plate 410 (the squeezing block 417 is not located in the groove 47, which facilitates subsequent reset). The squeezing block 417 is stored in the storage groove 43 of the pin plate 42. At this time, the locking assembly 4 is in the unlocked state, and the machine cover device 1 and the lower part of the machine cover device 2 can be disassembled.

[0033] When installation is required, the top of the lifting plate 414 and the outer surface of the pin rod 46 should be on the same horizontal plane first. Then, the pin plate 42 should be placed outside the pin rod 46. At this time, the push-pull electromagnet 7 should be activated again to make the push-pull electromagnet 7 operate in the opposite way to the locked state. The previously compressed spring 48 will start to reset through the setting of the push-pull electromagnet 7, pushing the pin rod 46 to slide in the storage groove 43, thereby driving the lifting plate 414 to move. During the movement of the lifting plate 414, the pressing block 417 is no longer under pressure, the second spring 416 resets, and pushes the pressing block 417 to reset until the pressing block 417 is located in the positioning groove 45. At this time, the locking assembly 4 is in the locked state. At this time, the machine cover device 1 and the lower part of the machine cover device 2 are successfully installed.

[0034] Through the cycle of the above unlocking and locking process, the machine cover device 1 and the lower part of the machine cover device 2 can be quickly disassembled and assembled, which facilitates the maintenance and repair of the equipment.

[0035] Finally, the following points should be noted: First, in the description of this invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can refer to mechanical connection or electrical connection, or internal connection between two components, or direct connection.
