Description

Technical Field

[0001] This utility model relates to the field of brush fixing technology, and in particular to a special brush fixing device for internal cleaning of irradiation equipment. Background Technology

[0002] In industrial production, irradiation equipment is widely used in many fields such as food preservation, pharmaceutical sterilization, and material modification. Because the interior of irradiation equipment is constantly exposed to a unique radiation environment, it easily accumulates dust, impurities, and other contaminants. These contaminants not only affect the irradiation effect but also threaten the safety and stability of the equipment. Therefore, regular cleaning of the interior of irradiation equipment is crucial. During the cleaning process, the brush holder is a key auxiliary tool, and its performance directly affects the efficiency and quality of the cleaning work.

[0003] Currently, most of the fixtures commonly used for cleaning brushes inside irradiation equipment employ relatively simple mechanical structures. For example, some fixtures use a traditional one-piece clamp structure, which adapts to brush handles of specific sizes through a pre-set inner diameter of the clamp. The technical principle is to use the clamping force of the clamp to fix the brush. Other fixtures are based on a simple snap-on design, which achieves fixation by engaging the snap with a specific slot on the brush, mainly relying on the clamping force generated by the elastic deformation of the snap.

[0004] However, these traditional brush holders have significant limitations. They can only accommodate brushes of specific sizes, and once the size of the brush changes—whether it's a change in handle thickness or length—effective fixation becomes impossible. This forces operators to frequently change holders when different brush sizes are needed to clean different areas inside the irradiation equipment, significantly reducing cleaning efficiency and increasing time and labor costs. Therefore, a dedicated brush holder for cleaning the interior of irradiation equipment is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a special brush holder for internal cleaning of irradiation equipment, which aims to improve the problem that existing holders can only be used with brushes of specific sizes, resulting in frequent replacement of the holder during cleaning, which seriously reduces cleaning efficiency and increases costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A special brush holder for internal cleaning of irradiation equipment includes a support plate, and a fixing component is provided on the top of the support plate. The fixing component is used to quickly and stably fix the brush.

[0008] The fixing assembly includes a rotating column, which is fixedly connected inside the support plate. A transmission rod is rotatably connected to the outer wall of the rotating column, and a rotating block is slidably connected to the outer wall of the transmission rod. A transmission ring is rotatably connected inside the rotating block and rotates inside the support plate. A rubber block is fixedly connected to one side of the transmission ring, and a fixing block is fixedly connected to the outer wall of the transmission ring. The bottom of the fixing block is fixedly connected to the upper surface of the support plate. A connecting column is fixedly connected to the top of the support plate. Both the fixing block and the connecting column are threaded with screws. A baffle is fixedly connected inside the support plate. A collar is fixedly connected to the top of the transmission ring, and a brush is slidably connected inside the collar. An adjustment assembly is provided at the bottom of the support plate for convenient length adjustment by the operator.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a sliding rod and a support rod. The sliding rod is fixedly connected to the bottom of the support plate, and the support rod is slidably connected to the outer wall of the sliding rod.

[0011] As a further description of the above technical solution:

[0012] A sleeve rod is fixedly connected to the top of the support rod, and a connecting block is fixedly connected to the outer wall of the sleeve rod;

[0013] As a further description of the above technical solution:

[0014] The sliding rod has multiple slots inside, and the connecting block has a drive shaft slidably connected inside.

[0015] As a further description of the above technical solution:

[0016] One end of the drive shaft is fixedly connected to a lever, and an anti-slip plate is fixedly connected to the side wall of the lever.

[0017] As a further description of the above technical solution:

[0018] The other end of the drive shaft is fixedly connected to a matching post, which matches the slot.

[0019] As a further description of the above technical solution:

[0020] A spring is provided on the outer wall of the drive shaft. One end of the spring is fixedly connected to one side of the mating post, and the other end is fixedly connected to the inner wall of the connecting block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by rotating the screw, the transmission ring rotates inside the support plate. The rotation of the transmission ring drives the rotating block and the rubber block to deflect synchronously. The rubber block quickly fixes and limits the brush, thereby achieving the effect of fixing brushes of different diameters. This solves the problem of frequent replacement due to poor compatibility of the fixing device, which cannot stably fix different specifications of brushes, and improves the overall efficiency of cleaning operations inside the equipment.

[0023] 2. In this utility model, by moving the lever, the transmission shaft slides inside the connecting block, which in turn drives the locking post to disengage from the slot. The movement of the locking post causes the spring to deform elastically, thereby achieving the effect of quickly adjusting the length of the component. This solves the problem of having to change tools and disassemble the fixing post when cleaning irradiation equipment areas at different depths because the length of the fixing post cannot be quickly adjusted, thus improving the flexibility of equipment operation.

Detailed Implementation

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a special brush holder for internal cleaning of irradiation equipment, including a support plate 1 for supporting other components and providing certain support. A fixing component is provided on the top of the support plate 1 for quickly and stably fixing the brush.

[0032] The fixed assembly includes a rotating column 2, which is fixedly connected inside the support plate 1. A transmission rod 3 is rotatably connected to the outer wall of the rotating column 2. A rotating block 4 is slidably connected to the outer wall of the transmission rod 3. A transmission ring 5 is rotatably connected inside the rotating block 4. The rotating block 4 is connected to the transmission ring 5 through a bearing, thereby enabling it to rotate and further transmit force. The transmission ring 5 rotates inside the support plate 1. A rubber block 6 is fixedly connected to one side of the transmission ring 5 for clamping and fixing the brush 12 and increasing friction. A fixing block 7 is fixedly connected to the outer wall of the transmission ring 5. The bottom of the fixing block 7 is fixedly connected to the upper surface of the support plate 1. A connecting column 8 is fixedly connected to the top of the support plate 1. Both the fixing block 7 and the connecting column 8 are threaded with screws 9. A baffle 10 is fixedly connected inside the support plate 1. A collar 11 is fixedly connected to the top of the transmission ring 5. A brush 12 is slidably connected inside the collar 11 for efficient cleaning inside the irradiation equipment. An adjustment assembly is provided at the bottom of the support plate 1 to facilitate the operator to adjust the length of the equipment.

[0033] Specifically, when cleaning the inside of irradiation equipment, which requires the use of brushes 12 of different sizes and quick adjustment of the retainer length to adapt to complex cleaning environments, the operator inserts the brush 12 into the collar 11. By rotating the screw 9, the screw 9 moves horizontally within the connecting column 8 and the fixing block 7. The movement of the screw 9 drives the transmission ring 5 to rotate within the support plate 1. During the rotation of the transmission ring 5, the rotating block 4 and the transmission rod 3 will be further offset synchronously. As the rotating block 4 and the transmission rod 3 offset, multiple rubber blocks 6 will also be squeezed inward synchronously. Through the uniform compression of these rubber blocks 6, the brush 12 is quickly fixed and limited, thus ensuring that the brush 12 will not loosen or shift during the cleaning process. At the same time, different types of brushes 12 can be quickly adjusted and fixed according to different cleaning needs, providing convenience for the operator.

[0034] Reference Figure 3 and Figure 4 The adjustment assembly includes a sliding rod 13 and a support rod 14. The sliding rod 13 is fixedly connected to the bottom of the support plate 1, serving as a guide and support. The support rod 14 is slidably connected to the outer wall of the sliding rod 13 to provide a sliding trajectory, allowing the sliding rod 13 to flexibly adjust the height of the brush 12 to adapt to different cleaning tasks. A sleeve rod 15 is fixedly connected to the top of the support rod 14, and a connecting block 17 is fixedly connected to the outer wall of the sleeve rod 15. Multiple slots 16 are provided inside the sliding rod 13 for cooperating with the engaging post 20 to achieve unlocking and locking. A drive shaft 18 is slidably connected inside the connecting block 17.

[0035] Specifically, when the working length of the brush 12 needs to be flexibly adjusted to clean areas of different depths and positions inside the irradiation equipment, when the operator moves the lever 19, the anti-slip plates 22 on both sides of the lever 19 increase the friction, effectively preventing the slippage of the hand during operation. The movement of the lever 19 causes the drive shaft 18 to slide synchronously under the guidance of the connecting block 17. As the drive shaft 18 slides, the engaging post 20 will disengage from the slot 16 under the action of force, thereby achieving quick unlocking. During the process of the engaging post 20 disengaging from the slot 16, the movement of the engaging post 20 itself will apply pressure to the spring 21, thereby causing the spring 21 to undergo elastic deformation and store a certain amount of elastic potential energy.

[0036] Reference Figure 3 and Figure 4 One end of the drive shaft 18 is fixedly connected to a lever 19, which is used to transmit the force applied by the operator and drive the subsequent components to move. The side wall of the lever 19 is fixedly connected to an anti-slip plate 22 to prevent the operator from slipping. The other end of the drive shaft 18 is fixedly connected to a locking post 20, which engages with the slot 16 to unlock and lock the components and ensure the stability of the components. A spring 21 is provided on the outer wall of the drive shaft 18 to provide elastic restoring force. One end of the spring 21 is fixedly connected to one side of the locking post 20, and the other end is fixedly connected to the inner wall of the connecting block 17.

[0037] Specifically, in the unlocked state, the operator can directly pull the sliding rod 13. The sliding rod 13 adjusts the length of the device by sliding up and down inside the support rod 14 and the sleeve rod 15. The support rod 14 provides stable support to ensure that the sliding rod 13 does not shift during adjustment, while the sleeve rod 15 acts as a guide. When the sliding rod 13 is adjusted to the required length position, the elastic potential energy of the spring 21 will push the engaging post 20 to re-insert into the slot 16. At this time, the engaging post 20 re-engages with the slot 16, thereby keeping the component stable and preventing loosening during use. This provides the operator with a convenient adjustment method and improves the flexibility and operability of the device.

[0038] Working principle: When using this device, the operator inserts the brush 12 into the collar 11. By rotating the screw 9, the screw 9 moves horizontally within the connecting column 8 and the fixing block 7. The movement of the screw 9 drives the transmission ring 5 to rotate within the support plate 1. Simultaneously, the rotation of the transmission ring 5 causes the rotating block 4 and the transmission rod 3 to move out of position, thus causing multiple rubber blocks 6 to press inwards synchronously. This pressing of the rubber blocks 6 quickly and securely fixes the brush 12. The operator can quickly change and fix different brushes 12 according to different cleaning needs. When the length of the device needs to be adjusted, the operator moves the lever 19. The anti-slip pads 22 on both sides of block 19 prevent slippage during operation. The movement of block 19 causes the drive shaft 18 to slide synchronously inside the connecting block 17. When the drive shaft 18 slides, it will drive the locking post 20 to disengage from the slot 16 to unlock. The movement of the locking post 20 will compress the spring 21 to cause it to deform elastically. After unlocking, the sliding rod 13 can be pulled directly to slide inside the support rod 14 and the sleeve rod 15 to achieve the adjustment effect. When the required length is reached, the elastic potential energy of the spring 21 will push the locking post 20 to re-engage in the slot 16 to fix it. This allows the operator to quickly adjust the equipment and provides flexibility.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
