Technical Field
[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding equipment for wood carving. Background Art
[0002] Wood carving is a kind of sculpture, which is often called "folk craft" in our country. Wood carving can be divided into three categories: three-dimensional round carving, root carving and relief carving. Wood carving is a type of work separated from carpentry. In our country's job classification, it is "fine carpentry". Wood carving requires the use of grinding equipment to grind its materials during the production and processing process. Among them, pen-type grinder is the most commonly used in the subsequent finishing of wood carving.
[0003] The existing pen-type grinder is favored by wood carving masters because of its small size and easy operation. However, the pen-type grinder is easily neglected when not in use due to its small size. It often falls from the tool table and touches the ground, causing damage to the grinder head, which has to be replaced.
[0004] Therefore, a wood carving grinding device is needed to solve the problem that the pen-type grinder in the prior art is small in size and easy to fall, causing the grinding head to be damaged after touching the ground. Utility Model Content
[0005] In order to solve the above technical problems, a wood carving grinding device is provided, which solves the problem in the prior art that the pen-type grinder is small in size and easy to fall, causing the grinding head to be damaged after touching the ground.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a wood carving grinding device, including a pen-type grinder body and a grinding head installed on the output end of the pen-type grinder body, characterized in that: a small sheath is provided on a threaded sleeve on one side of the rod of the pen-type grinder body close to the grinding head, and a locking component is provided on the side of the small sheath away from the grinding head;
[0007] The locking component includes a propulsion block fixed to one side of the small sheath in a truncated cone shape and slidably sleeved on the outside of the pen-type grinder body. A fixed block is fixedly sleeved on the rod body of the pen-type grinder body on one side of the propulsion block. A plurality of buckle rods are fixed to the fixed block on the side facing the propulsion block. The buckle rods are composed of an isosceles trapezoidal block and a long strip block. The long strip block is fixed on the fixed block. The inclined surface end of the isosceles trapezoidal block faces the propulsion block. The small sheath is also provided with an annular groove adapted to the inclined surface end of the isosceles trapezoidal block.
[0008] Preferably, a sealing ring is fixedly provided on the small sheath shaft at one side of the annular groove, and a large sheath corresponding to the sealing ring is threadedly provided on the fixing block.
[0009] Preferably, an unlocking block in the shape of an isosceles trapezoid is fixed on one side of the long block facing the pen-type grinder body, and a sliding ring is also slidably sleeved on the pen-type grinder body, and the sliding ring is located between the unlocking block and the fixed block.
[0010] Preferably, a sealing disk is fixed to a side of the large sheath away from the sealing ring, and the sealing disk is slidably penetrated by the pen-type grinder body.
[0011] Compared with the prior art, the advantages of the utility model are:
[0012] (1) By providing the small protective cover, when the pen-type grinder body is not in use, the small protective cover is screwed to cover the grinding head, thereby solving the problem in the prior art that the grinding head is damaged after the pen-type grinder touches the ground due to its small size and easy to fall.
[0013] (2) By setting the locking component, when the main body of the pen-type grinder is not in use, the sliding ring can be moved along the rod of the main body of the pen-type grinder so that it abuts against the inclined surface of the unlocking block. As the sliding ring continues to move, the unlocking block is pushed to drive the long strip block to undergo plastic deformation outward, and drive the right-angled trapezoidal block to separate from the annular groove, thereby releasing the locking effect of the buckle rod on the small sheath.
[0014] (3) By configuring the large sleeve, the sealing ring and the sealing disk, the large sleeve and the sealing ring can be used to isolate the debris generated when the grinding head grinds the wood carving outside the large sleeve and the sealing ring. The sealing disk can be used to prevent the splashing debris from entering the large sleeve from the other end of the large sleeve, thereby preventing the threaded engagement between the large sleeve and the fixed block from being blocked.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0022] Reference Figures 1 to 4 As shown, a wood carving grinding device comprises a pen-type grinding machine body 1 and a grinding head 2 installed on the output end of the pen-type grinding machine body 1, a small sheath 3 is provided on a threaded sleeve on one side of the rod of the pen-type grinding machine body 1 close to the grinding head 2, and a locking component is provided on the side of the small sheath 3 away from the grinding head 2;
[0023] The locking component includes a push block 6 fixed to one side of the small sheath 3 in a truncated cone shape, and is slidably sleeved on the outside of the pen-type grinder body 1. A fixed block 10 is fixedly sleeved on the rod of the pen-type grinder body 1 on one side of the push block 6. A plurality of buckle rods 8 are fixed to the side of the fixed block 10 facing the push block 6. The buckle rod 8 consists of a right-angled trapezoidal block and a long strip block. The long strip block is fixed on the fixed block 10, and the inclined surface end of the right-angled trapezoidal block faces the push block 6. The small sheath 3 is also provided with an annular groove 7 adapted to the inclined surface end of the isosceles trapezoidal block.
[0024] An unlocking block 11 in the shape of an isosceles trapezoid is fixed on one side of the long block facing the pen-type grinder body 1 . A sliding ring 9 is also slidably sleeved on the pen-type grinder body 1 . The sliding ring 9 is located between the unlocking block 11 and the fixed block 10 .
[0025] By setting the locking component, when the pen-type grinder body 1 needs to be used, the small sheath 3 can be twisted to make it rise along the rod of the pen-type grinder body 1 until the grinding head 2 at the output end of the pen-type grinder body 1 in the small sheath 3 is exposed. During this process, the inclined surface of the push block 6 abuts against the inclined surface of the right-angled trapezoidal block on the buckle rod 8. As the small sheath 3 continues to rise, the right-angled trapezoidal block slides on the inclined surface of the push block 6 until it slides onto the small sheath 3. During this process, the right-angled trapezoidal block drives the long strip block to undergo plastic deformation. Subsequently, when the right-angled trapezoidal block slides on the small sheath 3 to the annular groove 7, the right-angled trapezoidal block is driven by the reset of the long strip block. It is embedded in the annular groove 7, and then the locking effect of the small sheath 3 is completed. When the pen-type grinder body 1 is not in use, the sliding ring 9 can be moved along the rod body of the pen-type grinder body 1 to make it abut against the inclined surface of the unlocking block 11. As the sliding ring 9 continues to move, the unlocking block 11 is pushed to drive the long strip block to undergo plastic deformation outward, and drive the right-angled trapezoidal block to separate from the annular groove 7. In this way, the locking effect of the buckle rod 8 on the small sheath 3 can be released, and then the small sheath 3 is twisted to cover the grinding head 2. In this way, the problem of the grinding head being damaged after touching the ground due to the small size and easy falling of the pen-type grinder in the prior art can be solved.
[0026] However, after using it for a period of time, it was found that a large amount of debris splashed into the annular groove 7 when the grinding head 2 was grinding the wood carving. If the debris in the annular groove 7 was not cleaned up, it would affect the locking effect of the right-angled trapezoidal block of the buckle rod 8 on the annular groove 7.
[0027] In view of this, refer to Figures 1 to 4 As shown, it is worth mentioning that a sealing ring 5 is fixed on the rod body of the small sheath 3 on one side of the annular groove 7, a large sheath 4 corresponding to the sealing ring 5 is threadedly sleeved on the fixed block 10, and a sealing disk 12 is fixed on the side of the large sheath 4 away from the sealing ring 5, and the sealing disk 12 is slidably penetrated by the pen-type grinder body 1.
[0028] Through the arrangement of the large sheath 4, the sealing ring 5 and the sealing disk 12, after the right-angled trapezoidal block of the snap rod 8 locks the annular groove 7, the large sheath 4 is twisted to make it descend along the rod body of the fixed block 10 until it abuts against the sealing ring 5. In this process, the large sheath 4 completely covers the snap rod 8 and the annular groove 7, and the inner wall of the large sheath 4 abuts against the snap rod 8, thereby enhancing the locking effect of the snap rod 8 on the annular groove 7. Through the arrangement of the large sheath 4 and the sealing ring 5, the debris generated when the grinding head 2 grinds the wood carving can be isolated outside the large sheath 4 and the sealing ring 5. Through the arrangement of the sealing disk 12, the splashing debris is prevented from entering the large sheath 4 from the other end of the large sheath 4, causing the problem of obstruction of the threaded engagement between the large sheath 4 and the fixed block 10.
[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
