Description

Technical Field

[0001] The invention relates to the technical field of rotating shaft shells, in particular to a rotating shaft shell connection structure. Background Art

[0002] A shaft is a shaft used to connect the main parts of a product. It can withstand both bending moments and torques during operation. The shaft housing connection structure usually involves the coordinated use of multiple components to achieve stable rotation and support.

[0003] The existing shaft housing connection structure is installed by bolts, and it does not have the function of quick disassembly and assembly during daily maintenance, making the maintenance work cumbersome.

[0004] Therefore, we propose a shaft housing connection structure that can quickly disassemble and assemble the shaft housing so that maintenance personnel can quickly perform maintenance work on it. Summary of the invention

[0005] The object of the present invention is to provide a shaft-housing connection structure to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, the disassembly and assembly component includes a slip ring slidably arranged on the outer wall of the shell B, the outer wall of the slip ring is provided with a sliding groove, the inner wall of the sliding groove is provided with an inclined groove, the inner wall of the inclined groove is slidably provided with a sliding column, the outer wall of the sliding column is fixedly provided with a pin, the top surface of the slip ring is fixedly provided with a sliding rod, the outer wall of the sliding rod is sleeved with a first spring, the outer wall of the sliding rod is slidably provided with a fixed block, and the outer wall of the shell B is provided with a sliding hole.

[0008] Preferably, the clamping assembly includes a first limit groove formed on the outer wall of the rotating shaft body, a limit rod is fixedly installed on the inner wall of the first limit groove, a second spring is sleeved on the outer wall of the limit rod, a hook is slidably provided on the inner wall of the first limit groove, a clamping slot is formed at the bottom of the outer shell B, and an anti-theft hole is formed on the inner wall of the clamping slot.

[0009] Preferably, the auxiliary component comprises a second limiting groove formed on the inner wall of the card slot, a sleeve block is slidably arranged on the inner wall of the second limiting groove, a screw is sleeved inside the sleeve block, and an extrusion block is fixedly mounted on the outer wall of the sleeve block.

[0010] Preferably, the outer wall of the fixed block is fixedly installed to the outer wall of the rotating shaft body, the fixed block is fixedly installed to one end of the first spring on the side close to the slip ring, and the end of the first spring away from the fixed block is fixedly installed to the side of the slip ring close to the fixed block. Under its restriction, when the bayonet pin is aligned with the hole opened on the outer wall of the rotating shaft body, the slip ring is pushed away from the fixed block under the action of the elasticity of the first spring, and the sliding column is squeezed through the inclined groove, so that the bayonet pin is stably engaged in the hole opened on the outer wall of the rotating shaft body.

[0011] Preferably, the pin is arranged in an inclined surface at one end away from the sliding column, and the sliding column fixedly installed on the outer wall of the pin is slidably arranged with the inner wall of the inclined groove opened on the inner wall of the slide groove, and the inclined groove is opened on the inner wall of the slide groove at an angle. Under the restriction of the inclined inclined groove, when the slip ring moves downward, the inner wall of the inclined groove and the outer wall of the sliding column slide and squeeze, so that the four pins are gathered together to enable the pins to be engaged with the holes opened on the outer wall of the rotating shaft body.

[0012] Preferably, the end of the hook away from its inclined surface is slidably arranged with the outer wall of the limit rod, and the outer wall of the hook is arranged in an inclined surface. The hook arranged on the inclined surface can facilitate the installation of the shell A and the shaft body. The hook and the outer wall of the limit rod are slidably arranged, which can ensure that the second spring stably applies pressure to the hook, so that the hook and the slot are stably engaged.

[0013] Preferably, the extrusion block is arranged in an inclined surface at one end away from the sleeve block, and the outer wall of the extrusion block is slidably arranged with the inner wall of the slot. Under its restriction, when the screw rotates, the extrusion block can be driven to slide inside the slot to squeeze the hook so that the hook is no longer engaged with the slot, so as to disassemble the shell A and the shaft body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The shaft housing connection structure is composed of a disassembly assembly component. When the housing B needs to be installed on the outer wall of the shaft body, the housing A is first sleeved on the outer wall of the shaft body, and then the housing B is sleeved on the outer wall of the shaft body, so that the inclined surface of the bayonet away from the end of the sliding column slides and squeezes the outer wall of the shaft body. When the bayonet is not squeezed, the first spring is not squeezed at this time. The first spring pushes the slip ring away from the fixed block, so that the inner wall of the inclined groove opened on the outer wall of the slip ring is squeezed with the sliding column fixedly installed at one end of the bayonet away from its inclined surface, so that the bayonet is engaged with the hole opened on the outer wall of the shaft body. When the housing B and the shaft body need to be disassembled, the slip ring is pushed upward. Due to the outer wall of the fixed block and the shaft body, the slip ring is pushed upward. The outer wall of the body is fixedly installed, and the outer wall of the slide rod slides with the inside of the fixed block, so that the slip ring squeezes the first spring sleeved on the outer wall of the slide rod. When the slip ring moves toward the fixed block, the inner wall of the inclined groove opened on the inner wall of the slide groove slides and squeezes the outer wall of the slide column. Since the inclined groove is opened on the inner wall of the slide groove at an angle, the slide column slides in the inclined groove to drive the pin fixedly installed on the outer wall of the slide column to slide away from the shaft body, so that the pin is no longer engaged with the hole opened on the outer wall of the shaft body. When the pin is no longer engaged with the shaft body, the outer shell B is removed from the outer wall of the shaft body while the slip ring is pushed upward. This structure can quickly disassemble the outer shell B and the shaft body, so that maintenance personnel can maintain the shaft body and the outer shell B.

[0016] 2. The shaft shell connection structure is composed of a clamping assembly as one component. When the shell A needs to be installed on the outer wall of the shaft body, the clamping groove is aligned with the clamping hook, so that the inner wall of the clamping groove and one side of the inclined surface of the clamping hook slide and squeeze, so that the clamping hook slides on the outer wall of the limit rod to squeeze the second spring sleeved on the outer wall of the limit rod. When the limit rod is not restricted by the squeezing of the inner wall of the clamping groove, the limit rod is clamped on the inner wall of the clamping groove under the elasticity of the second spring, so that the shell A and the shaft body are quickly installed. When the shell A and the shaft body need to be disassembled, the maintenance personnel can use a tool to extend the tool into the anti-theft hole, so that the tool squeezes the inclined surface of the clamping hook, so that the clamping hook slides on the outer wall of the limit rod and squeezes the second spring. At this time, the clamping hook is no longer clamped with the clamping groove, and the shell A and the shaft body can be disassembled. After the installation of the shell A and the shaft body is completed, the operator can observe the clamping state of the clamping hook and the clamping groove from the anti-theft hole to ensure that the shell A and the shaft body are stably clamped.

[0017] 3. The shaft-shell connection structure is composed of an auxiliary component as one of its parts. When the shell A needs to be easily disassembled, the extrusion block is installed inside the slot. At this time, the operator rotates the screw. Since the outer wall of the sleeve block is slidably arranged with the inner wall of the second limit slot, and the end of the screw is rotatably connected with the inner wall of the second limit slot, under its restriction, the rotating screw can drive the extrusion block to move downward, so that the inclined surface of the end of the extrusion block contacts and squeezes the inclined surface of the hook, so that the hook slides on the outer wall of the limit rod, so that the hook is no longer engaged with the slot, so as to disassemble the shell A and the shaft body. This structure can quickly disassemble the shell A and the shaft body. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment, when it is necessary to install the shell B2 on the outer wall of the shaft body 1, the shell A3 is first sleeved on the outer wall of the shaft body 1, and then the shell B2 is sleeved on the outer wall of the shaft body 1, so that the inclined surface of the bayonet 415 away from one end of the slide column 414 slides and squeezes the outer wall of the shaft body 1. When the bayonet 415 is not squeezed, the first spring 418 is not squeezed at this time. The first spring 418 pushes the slip ring 411 away from the fixed block 417, so that the inner wall of the inclined groove 413 opened on the inner wall of the slide groove 412 opened on the outer wall of the slip ring 411 squeezes the slide column 414 fixedly installed at one end of the bayonet 415 away from its inclined surface, so that the bayonet 415 is engaged with the hole opened on the outer wall of the shaft body 1. When it is necessary to disassemble the shell B2 and the shaft body 1, the slip ring 411 is pushed upward. Since the outer wall of the fixed block 417 is fixedly installed on the outer wall of the shaft body 1, and the slide rod 416 The outer wall slides with the fixed block 417, so that the slip ring 411 squeezes the first spring 418 sleeved on the outer wall of the slide rod 416. When the slip ring 411 moves toward the fixed block 417, the inner wall of the inclined groove 413 opened on the inner wall of the slide groove 412 slides and squeezes the outer wall of the slide column 414. Since the inclined groove 413 is inclinedly opened on the inner wall of the slide groove 412, the slide column 414 slides inside the inclined groove 413, so as to drive the pin 415 fixedly installed on the outer wall of the slide column 414 to slide away from the shaft body 1, so that the pin 415 is no longer engaged with the hole opened on the outer wall of the shaft body 1. When the pin 415 is no longer engaged with the shaft body 1, the outer shell B2 is removed from the outer wall of the shaft body 1 while the slip ring 411 is pushed upward. This structure can quickly disassemble the outer shell B2 and the shaft body 1, so that maintenance personnel can maintain the shaft body 1 and the outer shell B2.

When the limiting rod 422 is not restricted by the squeezing of the inner wall of the slot 425, the limiting rod 422 is clamped on the inner wall of the slot 425 under the elastic action of the second spring 423 to quickly install the shell A3 and the shaft body 1. When disassembling the shell A3 and the shaft body 1, the maintenance personnel can use a tool to extend the tool into the anti-theft hole 426, so that the tool can squeeze the inclined surface of the hook 424, so that the hook 424 slides on the outer wall of the limit rod 422 and squeezes the second spring 423. At this time, the hook 424 is no longer engaged with the slot 425, and the shell A3 and the shaft body 1 can be disassembled. When the shell A3 and the shaft body 1 are installed, the operator can observe the engagement state of the hook 424 and the slot 425 through the anti-theft hole 426 to ensure that the shell A3 and the shaft body 1 are stably engaged.
