[0004] The lathe described in the patent document generates iron filings during use, which may be accompanied by the flying of iron filings. When the operator is near the lathe in use, he / she may be injured by the flying iron filings, which poses a certain safety hazard. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a lathe protective cover to solve the technical problem mentioned in the background art, which is that when a lathe is in use, it will generate iron filings, which may be accompanied by flying iron filings. When the operator is near the lathe in use, he / she may be injured by the flying iron filings, which poses a certain safety hazard.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A lathe protective cover includes a lathe body, a first mounting rod and a second mounting rod on the lathe body, a protective cover rotatably mounted on the first mounting rod, and a plurality of locking blocks formed along the length of the second mounting rod. The protective cover is fixedly provided with two limiting components for abutting against any two locking blocks and preventing the protective cover from rotating, and each of the two limiting components is provided with a limiting block for preventing the locking blocks from moving along the axis of the second mounting rod.

[0008] Working principle:

[0009] When the operator needs to use the protective cover, the protective cover is hinged to the first mounting rod and can rotate around the first mounting rod. When the protective cover rotates to the target angle, the limiting component engages with the locking block on the second mounting rod to prevent the protective cover from continuing to rotate. Then, the operator can prevent the locking block from moving along the axis of the second mounting rod by using the limiting block, thereby further preventing the axial movement of the protective cover.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, it is equipped with a snap-fit ​​block and a limiting component. The angle adjustment and secure locking of the protective cover can be achieved through the snap-fit ​​cooperation between the snap-fit ​​block and the limiting component.

[0012] Secondly, a limit block is provided. The axial constraint design of the limit block enhances the stability of the protective cover and prevents the protective cover from axial movement caused by vibration. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] like Figure 1 and Figure 2As shown, a lathe protective cover includes a lathe body 1. The lathe body 1 is provided with a first mounting rod 2 and a second mounting rod 3. A protective cover 4 is rotatably mounted on the first mounting rod 2. A plurality of locking blocks 5 are provided on the second mounting rod 3 along its length. The first mounting rod 2 is fixedly connected to the lathe body 1, and the protective cover 4 is hinged to the first mounting rod 2, that is, the protective cover 4 can rotate around the first mounting rod 2 to adjust the angle. The second mounting rod 3 is rotatably mounted on the lathe body 1. The plurality of locking blocks 5 arranged at intervals along the length of the second mounting rod 3 provide multiple fixing points for the protective cover 4. When the protective cover 4 rotates to the target angle, the second mounting rod 3 is rotated, and the locking blocks 5 on the second mounting rod 3 can rotate. Moreover, two limiting components abut against the two corresponding locking blocks 5 to prevent the protective cover 4 from rotating.

[0021] like Figure 2 and Figure 3 As shown, the protective cover 4 is fixedly provided with two limiting components for abutting against any two locking blocks 5 and preventing the protective cover 4 from rotating. The limiting components include a mounting block 7, a sliding block 8, a spring 9, and an abutment block 10. The mounting block 7 is fixedly disposed on the inner wall of the protective cover 4. A sliding groove 11 is formed in the mounting block 7. The sliding block 8 is slidably disposed in the sliding groove 11. The spring 9 is disposed in the sliding groove 11, and both ends of the spring 9 abut against the inner wall of the sliding groove 11 and the sliding block 8, respectively. A first through groove 12 is formed on one side of the mounting block 7. The abutment block 10 is fixedly disposed on the side of the sliding block 8. The abutment block 10 is slidably disposed in the first through groove 12, away from the end of the spring 9 and the abutment block 10 abuts against the locking block 5. The end of the abutment block 10 away from the sliding block 8 is inclined. When the protective cover 4 is rotated to the target angle, the locking block 5 on the second mounting rod 3 faces the first mounting rod 2. Then the operator rotates the second mounting rod 3, and the locking block 5 on the second mounting rod 3 abuts against the inclined surface on the abutment block 10, causing the abutment block 10 to drive the sliding block 8 to compress the spring 9. Thus, the locking block 5 is located between the abutment block 10 and the protective cover 4, preventing the protective cover 4 from rotating.

[0022] like Figure 2 and Figure 3As shown, both limiting components are provided with limiting blocks 6 to prevent the snap-fit ​​block 5 from moving along the axis of the second mounting rod 3. The limiting blocks 6 are fixed on the protective cover 4. The limiting blocks 6 have a receiving groove 13 for accommodating the snap-fit ​​block 5 and a second through groove 14. The abutting block 10 slides through the first through groove 12 and the second through groove 14 in sequence and extends into the receiving groove 13. The two ends of the snap-fit ​​block 5 abut against the inner wall of the receiving groove 13 and the outer wall of the abutting block 10, respectively. The receiving groove 13 on the limiting block 6 encloses the snap-fit ​​block 5 and guides the abutting block 10 to extend into the receiving groove 13 through the second through groove 14. When the protective cover 4 is fixed, the two ends of the snap-fit ​​block 5 abut against the inner wall of the receiving groove 13 and the outer wall of the abutting block 10, respectively, restricting the movement of the snap-fit ​​block 5 along the axis of the second mounting rod 3.

[0023] like Figure 2 and Figure 3 As shown, each of the two mounting blocks 7 has a first strip hole 15, and the protective cover 4 has two second strip holes 16, which are respectively connected to the two first strip holes 15. Each of the two sliding blocks 8 has a fixed rod 17, which slides through the corresponding first strip hole 15 and second strip hole 16 and extends outward from the protective cover 4. The protective cover 4 has a connecting rod 18, and the two ends of the connecting rod 18 are respectively fixed to the ends of the two fixed rods 17 away from the sliding block 8. When the connecting rod 18 is pulled, the two fixed rods 17 simultaneously drive the two sliding blocks 8 to slide.

[0024] like Figure 2 and Figure 3 and Figure 4 As shown, both ends of the connecting rod 18 are fixed with fixing blocks 19, and two rotating blocks 20 are rotatably provided on the protective cover 4. Each of the two rotating blocks 20 has a placement groove 21 for accommodating the fixing blocks 19. Bolts 22 are slidably passed through the two fixing blocks 19. The two bolts 22 are threadedly connected to the protective cover 4 respectively. The fixing blocks 19 at both ends of the connecting rod 18 are embedded in the placement grooves 21 of the rotating blocks 20, and the bolts 22 pass through the fixing blocks 19 and are threadedly connected to the protective cover 4, thereby restricting the movement of the connecting rod 18 and further preventing the protective cover 4 from shifting.

[0025] like Figure 1 As shown, the protective cover 4 is provided with an observation window 23, through which the machining status of the lathe can be monitored in real time without the need to frequently open and close the protective cover 4.

[0026] Working principle:

[0027] First, the operator rotates the protective cover 4. After the protective cover 4 is rotated to the target angle, the operator rotates the second mounting rod 3. The rotation of the second mounting rod 3 drives the locking block 5 to rotate, so that the locking block 5 can abut against the inclined surface on the abutment block 10 when rotating. Thus, the abutment block 10 is pushed by the pushing force of the locking block 5, pushing the sliding block 8. The sliding block 8 can then slide in the slide groove 11 and compress the spring 9. When the locking block 5 passes the abutment block 10 and enters the receiving groove 13, the abutment block 10 loses the pushing force of the locking block 5. Thus, the spring 9 releases the pushing force and pushes the sliding block 8 and the abutment block 10 to move. Thus, the locking block 5 is restricted between the receiving groove 13 and the abutment block 10. Then, the operator rotates the rotating block 20 and makes the fixing block 19 at the end of the connecting rod 18 located in the placement groove 21. The rotating block 20 can be fixed to the protective cover 4 by the bolt 22, thus completing the limiting of the protective cover 4 after rotation.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
