Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a portable polishing device for surface reconstruction. Background Technology

[0002] Surface reconstruction has different meanings in different fields, but its core is to reshape or reconstruct the surface morphology of an object. In the fields of science and engineering, surface reconstruction means surface treatment and repair. Through processes such as polishing, grinding, and coating, defects (such as scratches and wear) or morphology of an object's surface are optimized to make it smoother, flatter, or to meet specific functional requirements.

[0003] Polishing equipment is classified into large, medium, small, and micro types according to its size. Among them, small polishing equipment is mostly handheld polishers, which have the advantages of small size and high portability. However, existing handheld polishers still have certain shortcomings in use. The switch of the handheld polisher lacks a safety measure. When the operator accidentally touches the switch, especially a novice, it can easily cause the polishing head to cause accidental injury. To address this, a portable polishing device for surface reconstruction is proposed. Utility Model Content

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a portable polishing device for surface reconstruction includes a polishing machine body 1. A polishing head 2 is provided at the head of the polishing machine body 1, and a handle 3 is provided at the bottom of the tail of the polishing machine body 1. A switch 5 is provided at the junction of the polishing machine body 1 and the handle 3. A baffle 7 is provided between the switch 5 and the handle 3. An adjustment mechanism acting on the baffle 7 is provided on the handle 3.

[0016] The adjustment mechanism includes guide plates 8. Guide plates 8 are fixedly connected to both sides of the baffle 7 near the handle 3. The two guide plates 8 slide through the guide grooves 9 of the handle 3. The upper end of the guide plates 8 has a first locking hole 16 and a second locking hole 17. The first locking hole 16 and the second locking hole 17 are the same size and are distributed sequentially along the direction near the baffle 7. The side of the handle 3 away from the switch 5 has a mounting groove 11. A limiting mechanism acting on the first locking hole 16 or the second locking hole 17 is provided in the mounting groove 11.

[0017] The limiting mechanism consists of guide rods 12, lifting plate 13, locking pins 14, and springs 4. Two guide rods 12 are installed in the mounting groove 11, and the upper and lower ends of the guide rods 12 are fixedly connected to the upper and lower inner walls of the mounting groove 11, respectively. Two through holes are opened on the lifting plate 13, and the two guide rods 12 slide through the two through holes opened on the lifting plate 13. Springs 4 are wound around the outside of the two guide rods 12, and the upper and lower ends of the springs 4 are fixedly connected to the top wall of the mounting groove 11 and the upper end of the lifting plate 13, respectively. Two locking pins 14 are fixedly connected to the lower end of the lifting plate 13. The locking pins 14 are adapted to the first locking hole 16, and the distance between the two locking pins 14 is equal to the distance between the two first locking holes 16.

[0018] In use, pull the lifting plate 13 upwards, causing the locking pin 14 to move away from the guide plate 8. At this time, the spring 4 is further compressed, moving the baffle 7 towards the switch 5, so that the baffle 7 blocks the back of the switch 5. At this point, the first locking hole 16 on the guide plate 8 aligns with the locking pin 14 at the bottom of the lifting plate 13. Release the lifting plate 13; under the restoring deformation of the spring 4, the lifting plate 13 will move downwards, and the locking pin 14 at the bottom of the lifting plate 13 will engage with the first locking hole 16, thus fixing the positions of the guide plate 8 and the baffle 7. At this time, the baffle 7 can... To prevent the switch 5 from being accidentally activated and causing injury to the workers from the grinding head 2, the lifting plate 13 is pulled upwards again when the switch 5 needs to be activated. This causes the locking pin 14 to disengage from the first locking hole 16. The baffle 7 is then moved away from the switch 5 until the second locking hole 17 on the guide plate 8 is aligned with the locking pin 14. The lifting plate 13 is then released, allowing the locking pin 14 to be inserted into the second locking hole 17. The positions of the guide plate 8 and the baffle 7 are then fixed again. At this point, the position of the baffle 7 will not affect the activation of the switch 5.

[0019] The handle 3 has a storage slot 10 on its side wall near the switch 5.

[0020] The baffle 7 can be stored in the storage slot 10 to prevent the retracted baffle 7 from affecting the switch 5.

[0021] Among them, the outer wall of the handle 3 is fixedly fitted with an anti-slip sleeve 6.

[0022] The anti-slip sleeve 6 can increase the friction when the user's hand grips the device.

[0023] This utility model provides a portable polishing device for surface reconstruction, the specific working principle of which is as follows: In use, pull the lifting plate 13 upwards, causing the locking pin 14 to move away from the guide plate 8. At this time, the spring 4 is further compressed, moving the baffle 7 towards the switch 5, so that the baffle 7 blocks the back of the switch 5. At this point, the first locking hole 16 on the guide plate 8 aligns with the locking pin 14 at the bottom of the lifting plate 13. Release the lifting plate 13; under the restoring deformation of the spring 4, the lifting plate 13 will move downwards, and the locking pin 14 at the bottom of the lifting plate 13 will engage with the first locking hole 16, thus fixing the positions of the guide plate 8 and the baffle 7. At this time, the baffle 7 can block the switch 5. To prevent accidental activation of switch 5, which could lead to injury to workers from grinding head 2, when switch 5 needs to be activated, pull the lifting plate 13 upwards again to disengage the locking pin 14 from the first locking hole 16. Move the baffle 7 away from switch 5 until the second locking hole 17 on the guide plate 8 is aligned with the locking pin 14. Release the lifting plate 13, allowing the locking pin 14 to insert into the second locking hole 17. Then, fix the positions of the guide plate 8 and the baffle 7 again. At this time, the baffle 7 will be located in the storage slot 10 on the handle 3, preventing the baffle 7 from affecting the activation of switch 5.

[0024] It should be noted that the selection of spring 4 requires the following condition to be met: when the locking pin 14 is inserted into the first locking hole 16, spring 4 is still in a compressed state and the compression force is small.

[0025] The internal structure of the handheld polisher is based on existing technology and has not been improved here, so it is not described. Its internal structure can be referenced from the handheld pneumatic polisher with model number JQB-953.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
