Description

Technical Field

[0001] This utility model relates to the technical field of cutting blade devices, specifically to a high-efficiency cutting blade structure. Background Technology

[0002] Slicing is widely used in material segmentation and other fields. Generally, a drive mechanism is used to rotate the blade to cut other materials. The blade is usually fixed with screws or fitted. If the blade is damaged or needs to be replaced, the removal of the screw-fixed or fitted blade is more troublesome and time-consuming, which reduces the efficiency of slicing and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a high-efficiency cutting blade structure, including a blade body and a locking mechanism. A protrusion is provided at the center of the back side of the blade body, and an insertion hole is formed along the axial direction of the protrusion. A locking hole communicating with the insertion hole is provided on the peripheral wall of the protrusion. The locking mechanism includes an upper body, a lower body, and an elastic element. The upper body and the lower body each have a support leg one and a support leg two at their ends. The upper body and the lower body are elastically slidably connected by the support leg one and the elastic element. When force is applied, the upper body and the lower body move in opposite directions. When the support leg two is aligned with the corresponding locking hole, the external force is removed, and the upper body and the lower body move towards each other through the elastic element. The support leg two is inserted into the locking hole simultaneously, and its end protrudes outward from the wall of the locking hole.

[0005] This solution improves the blade structure by placing a protrusion on the blade body. The protrusion's insertion hole engages with the docking column at the blade holder. The locking mechanism uses two legs at the upper and lower bases to insert into the locking hole and protrude outward from the hole wall. The ends of the two protruding legs are inserted into the grooves formed on the peripheral wall of the docking column to form an axial lock. This allows for quick blade replacement and improves efficiency.

[0006] Furthermore, it also includes a hook mechanism, which includes a hook and a hanging post. The tail end of the hook is pivotally connected to the upper seat and the hanging post is provided at the corresponding lower seat. Rotating the hook causes the hook to engage or disengage with the hanging post. When in the engaged state, the separation of the upper seat and the lower seat in the sliding direction is restricted.

[0007] This design incorporates a hook mechanism. After the legs at the upper and lower seats are inserted into the locking holes, the hook can be rotated to engage with the hanging post, thereby restricting the separation of the upper and lower seats, stabilizing the locking state, and improving stability.

[0008] Furthermore, the first support leg in the upper body is inserted into the slot formed on the second support leg in the lower body to form a sliding connection. The slot walls of the first support leg in the upper body and the second support leg in the lower body are connected by an elastic element, which simplifies the sliding connection structure of the upper and lower bodies and facilitates assembly.

[0009] Furthermore, the elastic element is a spring.

[0010] Furthermore, the front side of the blade body has a downwardly extending bevel shape, which allows for better slicing.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2As shown, the high-efficiency cutting blade structure in this example includes a blade body 1 and a locking mechanism 2. The blade body 1 is disc-shaped, with a downwardly extending inclined surface 10 on the front side. A protrusion 3 is integrally formed at the center of the back side of the blade body 1. The protrusion is like a common rectangle. An insertion hole 11 extends axially from the end of the protrusion 3. The insertion hole is also rectangular. In use, the end of the docking post at the blade holder is also rectangular. The end of the docking post is inserted into the insertion hole, and its peripheral wall is fitted with the hole wall. This structure helps to limit the relative rotation between the two and improve stability.

[0021] A lock hole 12, which communicates with the insertion hole, is formed on the peripheral wall of the protrusion 3, such as... Figure 1 As shown, a lock hole 12 is formed longitudinally on the top surface of the protrusion 3, and a lock hole 12 is formed longitudinally on the bottom surface of the corresponding protrusion 3.

[0022] In this example, a locking mechanism is added. Locking mechanism 2 includes an upper seat 21, a lower seat 22, and an elastic element 25. Both the upper seat 21 and the lower seat 22 have a first support leg 23 and a second support leg 24 at their ends, so that both are groove-shaped as a whole. Figure 2 As shown, in its normal state, the upper seat 21 and the lower seat 22 form a frame with a notch.

[0023] The upper seat 21 and the lower seat 22 are elastically slidably connected by a support leg 23 and an elastic element 25. For example, the support leg 23 is formed longitudinally at the left end of the upper seat 21 and at the left end of the lower seat 22. A slot 28 is formed axially at one end of the support leg in the lower seat. The support leg 23 in the upper seat 21 is inserted into the slot 28 to form a sliding connection. As for the elastic element, a spring can be used as the elastic element 25. The elastic element 25 is sleeved on the support leg 23 in the upper seat 21. One end of the elastic element 25 is fixed to the peripheral wall of the support leg 23 in the upper seat 21, and the other end of the elastic element 25 is fixed to the slot wall in the lower seat 22, thereby forming an elastically slidable connection between the upper and lower seats.

[0024] In use, if force is applied to move the upper and lower seats in opposite directions, when the second support leg is aligned with the corresponding lock hole, the external force is removed and the upper and lower seats move towards each other through the elastic element. The second support leg is inserted into the lock hole simultaneously, and its end protrudes outward from the lock hole wall. When the docking column at the tool holder is inserted into the insertion hole, the end protruding outward from the lock hole wall is simultaneously inserted into the groove on the peripheral wall of the docking column to complete the axial locking.

[0025] In this example, a hook mechanism is added, such as... Figure 1 , Figure 2As shown, the hook mechanism includes a hook 26 and a hanging post 27. The hook 26 is a common L-shape. The tail end of the hook 26 is pivotally connected to the protruding post of the upper seat 21. The corresponding lower seat 22 has a protruding post 27. Rotating the hook causes the hook to engage or disengage from the hanging post. When engaged, the separation of the upper and lower seats in the sliding direction is restricted, which helps to improve the stability of the locking.

[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
