When the protrusions are received in the grooves, the limitation of the second body 3 in the first direction D1 is achieved.
Specifically, fig. 4 is a schematic diagram of stress analysis in the self-locking structure; the arc limiting surface 111 applies a force F1 to the lock tongue 15 to act on a point P1 during abutting, a direction extension line of the force F1 intersects with the virtual surface L1 at a point O1, and the virtual plane L1 passes through a pivot center O2 of the lock tongue 15 and is perpendicular to the first direction D1; the pivot center O2 of the latch 15 is directed to the outside of the first body in a direction of the intersection point O1. Namely, the invention needs to make a relative design for the lock tongue 15 and the corresponding arc limiting surface 111, so that the extension line or the reverse extension line of the interaction force between the two can pass through the upper part of the pivot center O2 of the lock tongue 15 (the position close to the outer side of the machine body is the upper part).
As shown in fig. 4, the force F1 is formed by combining a force F1t passing through the pivot center and another force F1n perpendicular to the force F1t, and because of the relative positional relationship between the force F1 and the pivot center O2, the direction of the other force F1n is directed to the outside of the first body, i.e. the other force F1n generates a rotational moment M1 as shown in the figure with respect to the pivot center O2, and at this time, the protrusion 151 of the locking bolt 15 engages with the groove wall 41 of the chute on the first body 2, and the aforementioned rotational moment M1 causes the two to engage more tightly at the engagement surface, thereby realizing the self-locking function of the locking bolt.
In addition, in the present embodiment, the first limiting portion 11 is L-shaped, and the protruding portion 151 of the lock tongue 15 is engaged with the slot wall 41 of the chute on the first body 2, and the first limiting portion 11 can limit the lock tongue 15 in two directions, and the above-mentioned rotation moment M1 can also make the engagement between the first limiting portion 11 and the engagement surface of the lock tongue 15, which is approximately L-shaped, more tightly engaged, so the self-locking effect of the lock tongue can be better.
Of course, in other embodiments, the matching manner during self-locking may be various, for example, only one of the two matching manners may be adopted, and only the arc-shaped limiting surface 111 needs to abut against the lock tongue 15, so that the lock tongue 15 can be limited in the second direction.
Fig. 8 also illustrates the range of motion of the stopper, and the highest limit position that the stopper can reach. In the highest limit position, the groove wall 41 of the first body 2 generates a corresponding force F2 at P2. The torque design realizes the labor-saving, efficient and firm limiting of the lock tongue.
In this embodiment, the first direction D1 and the second direction D2 are preferably perpendicular to each other.

The self-locking structure is used for detachably connecting the first machine body and the second machine body;
the self-locking structure comprises a lock tongue, a first limiting part matched with the lock tongue and a reset unit for propping against the lock tongue, one end of the lock tongue is pivotally connected to the first machine body, the other end of the lock tongue is provided with an arc-shaped stress surface, the first limiting part is fixed on the second machine body, and the first limiting part comprises an arc-shaped limiting surface matched with the arc-shaped stress surface in a shape;
The lock tongue is operable to switch between an unlocking state and a locking state, when the unlocking state is switched to the locking state, after the first limiting part presses the lock tongue, the lock tongue pivots, after the first limiting part moves from one side of the lock tongue, which is close to the second machine body, to one side of the lock tongue, which is far away from the second machine body, along a first direction, the lock tongue pivots and resets under the action of the resetting force of the resetting unit until the arc-shaped stress surface of the lock tongue is abutted with the arc-shaped limiting surface, and then the lock tongue is limited by at least one of the first machine body or the second machine body; the edge of the lock tongue is provided with a protruding part, the first machine body is provided with a chute, and the protruding part slides in the chute to drive the lock tongue to switch between a locking state and an unlocking state;
The locking mechanism further comprises a button, the button is arranged on the outer surface of the second machine body, the lock tongue is provided with a guide surface matched with the button, and the linear motion of the button along the direction opposite to the second direction is converted into the pivoting motion of the lock tongue through the guide surface; the second direction is arranged at an angle with the first direction;
under the locking state, an intersection point O1 is formed between a direction extension line of the acting force F1 applied to the arc-shaped stress surface by the arc-shaped limiting surface and a virtual plane L1, the direction of the pivoting center O2 of the lock tongue points to the intersection point O1 and points to the outside of the first machine body, so that the extension line or the reverse extension line of the acting force F1 can pass through the upper part of the pivoting center O2 of the lock tongue, the virtual plane L1 passes through the pivoting center of the lock tongue and is perpendicular to the first direction, and the first direction D1 is the assembly direction of the first machine body and the second machine body.
2. The locking mechanism of claim 1, wherein the self-locking structure further comprises a second limit portion disposed between the first body and the second body and a second locking portion mated with the second limit portion;
the second locking part is spliced or separated from the second limiting part along the first direction, and in the locking state, the second locking part is spliced with the second limiting part so as to limit the second machine body to move along the second direction relative to the first machine body.
3. The locking mechanism of claim 1, wherein,
The reset unit comprises an elastic element, the first machine body is provided with a positioning hole, one end of the elastic element is contained in the positioning hole, and the other end of the elastic element is abutted to the lock tongue.
4. The locking mechanism of claim 2, wherein,
The second locking part is configured as a protrusion, and the protrusion is arranged on the second machine body and is adjacent to the button; the second limiting part is configured as a groove, and the groove is arranged on the first machine body to accommodate the protrusion.
5. The locking mechanism of claim 2, wherein,
The first direction is perpendicular to the second direction.
6. The locking mechanism of claim 1, wherein,
The locking mechanism further comprises a connecting structure, the connecting structure comprises a clamping groove arranged on the first machine body and a buckle arranged on the second machine body, and the buckle is inserted into the clamping groove.
7. The locking mechanism of claim 1, wherein,
The first limiting part is L-shaped.
8. The locking mechanism of claim 1, wherein,
In a locking state, the lock tongue keeps abutting against the first limiting part under the action of the reset force of the reset unit so as to limit the second body and the first body to be separated in a first direction, and the direction of the reset force is different from the first direction; in the unlocked state, the lock tongue is operatively separated from the first limiting portion against the action of the restoring force to allow the second body to be separated from the first body, and the first direction is an assembling direction of the first body and the second body.
9. A dust collector comprises a dust collector body and a dust cup component, and is characterized in that,
A locking mechanism as claimed in any one of claims 1 to 8 is arranged between the cleaner body and the dirt cup assembly; the first machine body is a dust collector machine body, and the second machine body is a dust cup component.
