Description

Technical Field

[0001] This utility model belongs to the field of clutch protection technology, and in particular relates to a clutch protection device. Background technology:

[0002] In existing technologies, clutch protection and transportation often face numerous challenges, especially in complex and variable operating environments. Traditional clutch protection methods often lack sufficient stability and adaptability, making clutches susceptible to damage during transportation and use. This not only increases maintenance costs but also affects the clutch's service life.

[0003] According to a public disclosure of a clutch protective device (publication number: CN218704583U), it includes a housing; a pull-out groove is provided on the side wall of the housing; a drawer is slidably connected inside the pull-out groove; a spring groove is provided on the top of the pull-out groove; multiple sets of limiting blocks are fixed to the top of the spring groove; the multiple sets of limiting blocks pass through the pull-out groove and the spring groove; a spring is fixed to the limiting block inside the spring groove; this step, by providing limiting blocks and the surface of the clutch contacting the drawer being inclined, reduces the possibility of the drawer detaching from the housing during transportation, thereby causing the clutch to fall off and be damaged, after the multiple sets of limiting blocks enter the drawer. By providing springs, when the operator pushes the drawer to contact the inclined surface of the limiting block, the limiting block can enter the drawer more smoothly, facilitating the operator's packing.

[0004] While the aforementioned application addresses the clutch protection issue during transportation to some extent through the combination of components such as the housing and drawers, it still has some shortcomings in practical applications. In complex and variable working conditions, the protection provided solely by the housing and drawers may not offer sufficient stability and adaptability, especially when the clutch is subjected to significant external impacts. Therefore, we propose a clutch protection device. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for clutches, which solves the problem of the inability to stably protect and transport clutches through the cooperation between components such as the lower plate, support leg and connecting plate in the protective device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a protective device for a clutch, including a clutch body and a main rotating sleeve. The main rotating sleeve is fixedly connected to the inner circumferential surface of the clutch body, and a protective device is provided at the bottom of the clutch body.

[0008] The protective device includes a lower plate, which is disposed at the bottom of the clutch body. A support leg is fixedly connected to the bottom of the lower plate, and a connecting plate is fixedly connected to the bottom of the lower plate. A motor is fixedly connected to the side of the connecting plate, and a drive gear is fixedly connected to the output shaft of the motor. A threaded rod is rotatably connected through the bottom of the lower plate. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A lower pressure plate is fixedly connected to the circumferential surface of the threaded sleeve. A limit lug is fixedly connected to the circumferential surface of the lower pressure plate. A limit groove is slidably connected to the side of the limit lug. A driven gear is fixedly connected to the end of the threaded rod away from the threaded sleeve.

[0009] Furthermore, a buffer spring is fixedly connected to the top of the lower plate, and the bottom of the limiting slide groove is fixedly connected to the top of the lower plate. Its function is to buffer the impact force when the clutch body is subjected to impact, reducing damage to the clutch body. Simultaneously, the limiting slide groove can limit the limiting lugs, making the lower pressure plate more stable during movement.

[0010] Furthermore, the end of the buffer spring away from the lower plate is located on the displacement trajectory of the bottom of the limiting support. The side cross-section of the limiting support is set in a convex shape. Its function is to compress the buffer spring when the limiting support moves on the buffer spring, so that the buffer spring can buffer the impact force on the lower pressure plate.

[0011] Furthermore, the driving gear and the driven gear mesh with each other. The number of teeth on the driving gear is less than the number of teeth on the driven gear. Its function is to drive the driving gear to rotate through the motor. Since the number of teeth on the driving gear is less than the number of teeth on the driven gear, the driven gear will rotate at a slower speed, thereby driving the threaded rod to rotate.

[0012] Furthermore, the number of limiting slides, limiting lugs and buffer springs is set to several, and they are arranged in a ring array along the top of the lower plate. The side cross section of the limiting slide is set to a U-shape, which makes the lower pressure plate move more smoothly. At the same time, the U-shaped limiting slide can also better limit the limiting lugs and prevent them from shifting during movement.

[0013] Furthermore, an airbag protection device is provided on the circumferential surface of the lower pressure plate. The airbag protection device includes a lower pressure support, which is fixedly connected to the circumferential surface of the lower pressure plate. A stop post is fixedly connected to the bottom of the lower pressure support. An airbag is fixedly connected to the top of the lower plate. An air supply pipe is fixedly connected through and to the side of the airbag. A protective airbag is fixedly connected to the end of the air supply pipe away from the airbag. Its function is that when the lower pressure plate is subjected to a downward impact force, the lower pressure support will drive the stop post to move downward. The stop post will squeeze the airbag, so that the gas inside the airbag enters the protective airbag through the air supply pipe, thereby causing the protective airbag to inflate and further protect the clutch body.

[0014] Furthermore, the top of the airbag is located on the displacement trajectory of the end of the abutment away from the lower pressure support. Several airbags and protective airbags are provided and arranged in a circular array along the top of the lower plate. Their function is to ensure that the clutch body can be protected by the airbag protective device, thereby further improving the safety of the clutch body.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves effective support and stable protection for the clutch body through the cooperation of components such as the lower plate, support legs, and connecting plate in the protective device. During clutch operation, it may be subjected to various external impacts. The lower plate allows the clutch body to be securely placed on it, while the support legs further enhance the stability of the entire device. Simultaneously, the connection between the connecting plate and the motor enables the driving gear to drive the driven gear to rotate, thereby moving the threaded rod and threaded sleeve to achieve the pressing operation of the lower plate on the clutch body. This pressing method is not only stable and reliable but also allows for adjustment of the pressing force according to actual needs.

[0017] 2. This utility model achieves further protection for the clutch body through the cooperation of components such as the lower pressure plate, the stop post, and the airbag in the airbag protection device. During clutch operation, the lower pressure plate is subjected to downward pressure. At this time, the lower pressure plate drives the stop post to move downward, and the stop post compresses the airbag. This causes the gas inside the airbag to quickly enter the protective airbag through the air supply pipe. The protective airbag then inflates, tightly wrapping around the clutch body, thereby effectively absorbing and dispersing the impact force and protecting the clutch body from damage. This airbag protection method is not only responsive but also has a significant protective effect, greatly improving the safety of the clutch during operation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model is a protective device for a clutch, including a clutch body 1 and a main rotating sleeve 2. The main rotating sleeve 2 is fixedly connected to the inner circumferential surface of the clutch body 1, and a protective device 3 is provided at the bottom of the clutch body 1.

[0029] The protective device 3 includes a lower placement plate 301, which is located at the bottom of the clutch body 1. A support leg 302 is fixedly connected to the bottom of the lower placement plate 301. A connecting plate 303 is fixedly connected to the bottom of the lower placement plate 301. A motor 304 is fixedly connected to the side of the connecting plate 303. A drive gear 305 is fixedly connected to the output shaft of the motor 304. A threaded rod 306 is rotatably connected through the bottom of the lower placement plate 301. A threaded sleeve 307 is threadedly connected to the circumferential surface of the threaded rod 306. A lower pressure plate 308 is fixedly connected to the circumferential surface of the threaded sleeve 307. A limit bracket 309 is fixedly connected to the circumferential surface of the lower pressure plate 308. A limit groove 310 is slidably connected to the side of the limit bracket 309. A driven gear 311 is fixedly connected to the end of the threaded rod 306 away from the threaded sleeve 307.

[0030] As shown in the figure, a buffer spring 4 is fixedly connected to the top of the lower plate 301, and the bottom of the limiting groove 310 is fixedly connected to the top of the lower plate 301. Its function is to buffer the impact force when the clutch body 1 is subjected to impact, reducing damage to the clutch body 1. Simultaneously, the limiting groove 310 can limit the limiting lug 309, making the lower pressure plate 308 more stable during movement.

[0031] As shown in the figure, the end of the buffer spring 4 away from the lower plate 301 is located on the displacement trajectory of the bottom of the limiting support 309. The side section of the limiting support 309 is set in a convex shape. Its function is to compress the buffer spring 4 when the limiting support 309 moves on the buffer spring 4, so that the buffer spring 4 can buffer the impact force on the lower pressure plate 308.

[0032] As shown in the figure, the driving gear 305 and the driven gear 311 mesh with each other. The number of teeth of the driving gear 305 is less than the number of teeth of the driven gear 311. Its function is to drive the driving gear 305 to rotate through the motor 304. Since the number of teeth of the driving gear 305 is less than the number of teeth of the driven gear 311, the driven gear 311 will rotate at a slower speed, thereby driving the threaded rod 306 to rotate.

[0033] As shown in the figure, there are several limiting slides 310, limiting lugs 309 and buffer springs 4 arranged in a ring array along the top of the lower plate 301. The side cross section of the limiting slide 310 is set in a U-shape, which makes the lower pressure plate 308 move more smoothly. At the same time, the U-shaped limiting slide 310 can also better limit the limiting lugs 309 and prevent them from deviating during movement.

[0034] As shown in the figure, an airbag protection device 5 is provided on the circumferential surface of the lower pressure plate 308. The airbag protection device 5 includes a lower pressure support 501, which is fixedly connected to the circumferential surface of the lower pressure plate 308. A stop post 502 is fixedly connected to the bottom of the lower pressure support 501, and an airbag 503 is fixedly connected to the top of the lower plate 301. An air supply pipe 504 is fixedly connected through the side of the airbag 503. A protective airbag 505 is fixedly connected to the end of the air supply pipe 504 away from the airbag 503. Its function is that when the lower pressure plate 308 is subjected to a downward impact force, the lower pressure support 501 will drive the stop post 502 to move downward, and the stop post 502 will squeeze the airbag 503, so that the gas inside the airbag 503 enters the protective airbag 505 through the air supply pipe 504, thereby causing the protective airbag 505 to expand and further protect the clutch body 1.

[0035] As shown in the figure, the top of the airbag 503 is located on the displacement trajectory of the end of the abutment 502 away from the lower pressure support 501. Several airbags 503 and protective airbags 505 are arranged in a ring array along the top of the lower placement plate 301. Their function is to ensure that the clutch body 1 is protected by the airbag protection device 5, thereby further improving the safety of the clutch body 1.

[0036] A specific application of this embodiment is as follows: First, the clutch is placed on the lower platen 301, then the lower pressure plate 308 is closed, and the motor 304 is started. The output shaft of the motor 304 drives the drive gear 305 to rotate. Since the drive gear 305 and the driven gear 311 mesh with each other, and the number of teeth of the drive gear 305 is less than the number of teeth of the driven gear 311, the driven gear 311 will drive the threaded rod 306 to rotate at a slower speed. The rotation of the threaded rod 306 causes the threaded sleeve 307 to move along the threaded rod 306 under the action of the thread, thereby pushing the lower pressure plate 308 to move downward and pressing and fixing the clutch body 1. During this process, the limiting lug 309 slides in the limiting groove 310, ensuring the stability of the movement of the lower pressure plate 308. At the same time, the buffer spring 4 can buffer the impact force when the lower pressure plate 308 is subjected to impact force, reducing the damage to the clutch body 1. In addition, when the pressure plate 308 is pressed down, the pressure support 501 will drive the abutment 502 to move downward. The abutment 502 squeezes the air bag 503, so that the gas inside the air bag 503 enters the protective air bag 505 through the air supply pipe 504. The protective air bag 505 expands to further protect the clutch body 1.
