When the latch portion 130 is engaged with the mounting head 211, the mounting head 211 is restrained within the first recess 111. When the latch 130 is disengaged from the mounting head 211, the mounting head 211 can be removed from the first recess 111.

Fig. 3 shows an assembled schematic view of another view of the locking mechanism 100 and the mounting mechanism 200 of the embodiment shown in fig. 1. Fig. 4 shows a cross-sectional view of the locking mechanism 100 and the mounting mechanism 200 of the embodiment of fig. 1, wherein the tongue portion 130 extends into the first recess 111. Fig. 5 shows a cross-sectional view of the locking mechanism 100 and the mounting mechanism 200 of the embodiment of fig. 1, wherein the tongue portion 130 exits the first recess 111.

Referring to fig. 2 and 3 in combination, in the locking mechanism 100, the latch bolt portion 130 includes a first latch bolt 131. The first latch bolt 131 is slidably connected to the first housing 110 along the first direction X. Specifically, the first housing 110 has two protruding strips disposed at intervals. The two raised strips are positioned in the accommodating groove, and a chute 1131 is formed between the two raised strips. The runner 1131 extends along a first direction X. The first lock tongue 131 is accommodated in the chute 1131, and two sides of the first lock tongue 131 contact the inner wall of the chute 1131, so that the chute 1131 can guide the first lock tongue 131 to slide along the first direction X. The mounting head 211 of the mounting mechanism 200 has a slot 2111, and when the mounting head 211 is inserted into the first concave groove 111, the first latch 131 may be inserted into the first concave groove 111 and into the slot 2111. When the first locking tongue 131 is inserted into the insertion groove 2111 of the mounting head 211, the first locking tongue 131 may prevent the mounting head 211 from being taken out of the first recess 111.

In the first direction X, the first latch tongue 131 includes a first rack portion 1311 and a first locking portion 1313, wherein the first locking portion 1313 faces the first recessed groove 111. The side wall of the first recess groove 111 is provided with a through hole, and the first locking portion 1313 can pass through the through hole and be inserted into the first recess groove 111 when the first locking tongue 131 moves in the first direction X.

The drive assembly 150 of the locking mechanism 100 includes a drive portion 151 and a gear portion 153. The driving part 151 is rotatably connected with the first housing 110. The driving portion 151 is in a limited connection with the gear portion 153 in a circumferential direction, so that when the driving portion 151 rotates relative to the first housing 110, the gear portion 153 also rotates relative to the first housing 110.

Optionally, the driving portion 151 includes a connecting rod 1511 and a dial knob 1513. The pulling button 1513 is disposed outside the accommodating cavity 113, one end of the connecting rod 1511 is in circumferential limit connection with the pulling button 1513, and the other end of the connecting rod 1511 is in circumferential limit connection with the gear portion 153. The knob 1513 is located outside the accommodating cavity 113, that is, the knob 1513 is located outside the first housing 110, so that a user can apply force to the knob 1513 to rotate the knob 1513. The rotation of the dial knob 1513 is transmitted to the gear portion 153 through the connection lever 1511, so that the gear portion 153 rotates. It will be appreciated that the connection between the driving portion 151 and the gear portion 153 may be a fixed connection, or may be a spline fit or other fit, so that the driving portion 151 can rotate the gear portion 153.

The gear portion 153 is engaged with the first rack portion 1311. When the gear portion 153 rotates, the first rack portion 1311 is driven to move in the first direction X, thereby driving the first locking portion 1313 to insert into or leave the first recess 111.

Referring to fig. 4 and 5 in combination, when the gear portion 153 drives the first rack portion 1311 to move toward the first recess groove 111, the first rack portion 1311 is inserted into the first recess groove 111 through the through hole on one side of the first recess groove 111 and passes through the mounting head 211 to pass out of the through hole on the other side of the first recess groove 111, so that the first locking portion 1313 penetrates the entire first recess groove 111. The parts of the first locking tongue 131 and the locking tongue 130 located at both sides of the first recess 111 are limited in displacement by the first housing 110, and the parts of the first locking tongue 131 and the locking tongue 130 are limited in displacement of the mounting head 211, so that the mounting head 211 is limited in the first recess 111. A locking engagement of the mounting mechanism 200 and the locking mechanism 100 is achieved.

When the gear portion 153 moves the first rack portion 1311 away from the first concave groove 111, the first rack portion 1311 is disengaged from the through hole of the side of the first concave groove 111 away from the gear portion 153. As the first rack portion 1311 moves further in the first direction X, the first rack portion 1311 is disengaged from the insertion groove 2111 of the mounting head 211, and the first recess 111 is adjacent to the through hole of the side of the gear portion 153. The first rack portion 1311 is moved away from the first recessed groove 111, thereby unlocking the engagement of the first rack portion 1311 with the mounting head 211, and the mounting head 211 can be removed from the first recessed groove 111 to release the connection of the mounting mechanism 200 and the locking mechanism 100.

Fig. 6 shows a cross-sectional view of the locking mechanism 100 in the embodiment shown in fig. 1. Fig. 7 shows an assembly schematic of the locking mechanism 100 in the embodiment of fig. 1.

Referring to fig. 6 and 7, the first housing 110 is further provided with a first positioning member 1101. The driving portion 151 is provided with a second positioning member 1515. The second positioning member 1515 rotates following the rotation of the dial knob 1513. When the second positioning member 1515 is rotated to align with the first positioning member 1101, the second positioning member 1515 may cooperate with the first positioning member 1101 to limit rotation of the driving portion 151 relative to the first housing 110. Optionally, the first positioning member 1101 includes a positioning groove 1103 provided to the first housing 110. The second positioning member 1515 includes a positioning projection 1519. A first collar 1512 is provided at a portion of the connection rod 1511 of the driving portion 151 located in the receiving cavity 113. The positioning protrusion 1519 is disposed on a face of the first collar 1512 facing the positioning groove 1103. When the positioning protrusion 1519 is aligned with the positioning groove 1103, the first collar 1512 is driven to move in the extending direction of the connecting rod 1511, so that the positioning protrusion 1519 is inserted into the positioning groove 1103.

Optionally, the locking mechanism 100 further includes an elastic member 170. One end of the elastic member 170 acts on the first housing 110, and the other end of the elastic member 170 acts on the driving assembly 150. The elastic member 170 provides an elastic force to the driving assembly 150 such that the positioning protrusion 1519 has a movement tendency to be inserted into the positioning groove 1103. Specifically, the elastic member 170 is a compression spring. The connection lever 1511 extends from a side of the first housing 110 near the dial knob 1513 to a side facing away from the dial knob 1513. A second collar 1514 is provided on the side of the connecting rod 1511 facing away from the dial knob 1513. The elastic member 170 is sleeved on the connecting rod 1511 and is clamped between the first housing 110 and the second convex ring 1514. When the user presses the dial 1513 toward the first housing 110, the positioning protrusion 1519 is away from the positioning groove 1103, and the first collar 1512 and the first housing 110 press the elastic member 170, so that the elastic member 170 generates or increases an elastic force that drives the dial 1513 back. The elastic force also drives the positioning projection 1519 toward the positioning groove 1103. When the user no longer presses the knob 1513, if the positioning protrusion 1519 aligns with the positioning groove 1103, the elastic member 170 releases the elastic potential energy, so that the driving assembly 150 moves relative to the first housing 110, and the positioning protrusion 1519 is inserted into the positioning groove 1103.

Optionally, the gear portion 153 extends into the runner 1131 to engage the first rack portion 1311. When the gear portion 153 is fixedly connected to the connecting rod 1511, if the elastic member 170 drives the connecting rod 1511 to move relative to the first housing 110, the gear portion 153 will also move relative to the first housing 110. Along the extension direction of the connecting rod 1511, the size of the gear portion 153 is smaller than the size of the runner 1131, so that the movement of the gear portion 153 can be prevented from being stopped by the inner wall of the runner 1131.

Optionally, a support 115 is also disposed within the first housing 110. The support 115 extends from the inner wall of the accommodation chamber 113 to the position of the connection rod 1511. The support 115 has a catching groove through which the connection rod 1511 passes. The support 115 may support the position of the connection rod 1511 and guide the movement of the connection rod 1511.

Optionally, the driving part 151 is provided with a plurality of positioning protrusions 1519 around the circumference of the connection rod 1511. Around the circumference of the connection rod 1511, the first housing 110 is provided with a plurality of positioning grooves 1103. When the driving part 151 rotates with respect to the first housing 110, the positioning protrusion 1519 may be aligned with the positioning groove 1103 at a plurality of angles, so that the driving part 151 may be locked with the first housing 110 at a plurality of angles.

The mounting mechanism 200 and the locking mechanism 100 in such an electrical apparatus can be assembled using the following means:

the mounting head 211 of the mounting mechanism 200 is inserted into the first concave groove 111 of the locking mechanism 100. Pressing the dial knob 1513 causes the positioning projection 1519 to disengage from the positioning groove 1103. Twisting the toggle 1513 causes the gear portion 153 to move the first rack portion 1311 in the first direction X such that the first locking portion 1313 approaches the first recess 111 in the first direction X. Continued pulling of the toggle 1513 causes the first locking portion 1313 to enter the first recessed channel 111 and be inserted into the slot 2111 of the mounting head 211. The first locking portion 1313 cooperates with the mounting head 211 to define the relative position of the mounting mechanism 200 and the locking mechanism 100. Releasing the dial knob 1513, the elastic member 170 drives the positioning projection 1519 to be inserted into the positioning groove 1103. The positioning protrusion 1519 cooperates with the positioning groove 1103 to prevent the dial 1513 from rotating the gear portion 153 to prevent the first locking portion 1313 from being disengaged from the slot 2111 of the mounting head 211 in the first direction X.

The mounting mechanism 200 and the locking mechanism 100 in such an electrical apparatus can be disassembled using the following manner:

pressing the dial knob 1513 causes the positioning projection 1519 to disengage from the positioning groove 1103. Twisting the toggle 1513 causes the gear portion 153 to move the first rack portion 1311 in the first direction X such that the first locking portion 1313 disengages from the slot 2111 of the mounting head 211 in the first direction X. When the first locking portion 1313 is disengaged from the slot 2111 of the mounting head 211, the engagement of the mounting head 211 with the first locking portion 1313 is released. Releasing the dial knob 1513, the elastic member 170 drives the positioning projection 1519 to be inserted into the positioning groove 1103. The positioning protrusion 1519 cooperates with the positioning groove 1103 to prevent the toggle 1513 from rotating the gear portion 153 again, so as to prevent the reinsertion of the first locking portion 1313 into the first recess 111, which affects the next insertion of the mounting head 211. The mounting head 211 of the mounting mechanism 200 is extracted from the first recess 111 of the lock mechanism 100.

Fig. 9 shows an assembled schematic view of another view of the locking mechanism 100 and the mounting mechanism 200 in the embodiment shown in fig. 8. Fig. 10 shows a cross-sectional view of the locking mechanism 100 in the embodiment of fig. 8.

As shown in fig. 8 and 9, the first housing 110 of this locking mechanism 100 has two first concave grooves 111 and two second concave grooves 117. The first concave grooves 111 and the corresponding second concave grooves 117 are disposed at intervals along the first direction X. The two first concave grooves 111 are disposed at intervals along the second direction Y. Two second concave grooves 117 are also provided at intervals along the second direction Y. The second housing 210 of the mounting mechanism 200 has four mounting heads 211, two of the mounting heads 211 being respectively inserted into the two first concave grooves 111, and the other two of the mounting heads 211 being respectively inserted into the two second concave grooves 117.

Locking mechanism 100 also includes a drive assembly 150 and two tongue portions 130. Each latch portion 130 corresponds to one of the first recessed grooves 111 and one of the second recessed grooves 117. The first housing 110 has a receiving cavity 113, and two latch portions 130 are disposed in the receiving cavity 113. The driving assembly 150 is used for driving the two latch bolt portions 130 to move, so that the latch bolt portions 130 can extend into the first concave groove 111 and the second concave groove 117 to be matched with the mounting head 211, or leave the first concave groove 111 and the second concave groove 117 to be disengaged from the mounting head 211.

A second collar 1514 is provided on the side of the connecting rod 1511 facing away from the dial knob 1513. The elastic member 170 is sleeved on the connecting rod 1511 and is clamped between the first housing 110 and the second convex ring 1514. When the user presses the dial 1513 toward the first housing 110, the positioning protrusion 1519 is away from the positioning groove 1103, and the first collar 1512 and the first housing 110 press the elastic member 170, so that the elastic member 170 generates or increases an elastic force that drives the dial 1513 back. The elastic force also drives the positioning projection 1519 toward the positioning groove 1103. When the user no longer presses the knob 1513, if the positioning protrusion 1519 aligns with the positioning groove 1103, the elastic member 170 releases the elastic potential energy, so that the driving assembly 150 moves relative to the first housing 110, and the positioning protrusion 1519 is inserted into the positioning groove 1103. It will be appreciated that one end of the resilient member 170 acts on the first housing 110 through the mounting frame 190 such that the drive assembly 150 is able to move relative to the housing in the second direction Y. If the first housing 110 is not provided with a detachable mounting frame 190.

Around the circumference of the connection rod 1511, the first housing 110 is provided with a plurality of positioning grooves 1103. When the driving part 151 rotates with respect to the first housing 110, the positioning protrusion 1519 may be aligned with the positioning groove 1103 at a plurality of angles, so that the driving part 151 may be locked with the first housing 110 at a plurality of angles.

The mounting mechanism 200 and the locking mechanism 100 in such an electrical apparatus can be assembled using the following means:

the four mounting heads 211 of the mounting mechanism 200 are inserted into the two first concave grooves 111 and the two second concave grooves 117 of the locking mechanism 100, respectively. Pressing the dial knob 1513 causes the positioning projection 1519 to disengage from the positioning groove 1103. Twisting the toggle 1513, the two sets of gear portions 153 move in synchronism. In each set of gear portions 153, the main gear 1531 rotates the first driven wheel 1533 and the second driven wheel 1535 about opposite rotational directions. The first and second rack portions 1311, 1331 move opposite in the first direction X such that the first locking portion 1313 approaches the first recessed slot 111 in the first direction X and the second locking portion 1333 approaches the second recessed slot 117 in the first direction X. Continued toggling of the toggle 1513 causes the first locking portion 1313 to enter the first recessed slot 111 and be inserted into the slot 2111 of the mounting head 211, and causes the second locking portion 1333 to enter the second recessed slot 117 and be inserted into the slot 2111 of the mounting head 211. The first locking portions 1313 cooperate with the corresponding mounting heads 211 to define the relative positions of the mounting mechanism 200 and the locking mechanism 100. The second locking portions 1333 cooperate with the corresponding mounting heads 211 to define the relative positions of the mounting mechanism 200 and the locking mechanism 100. Releasing the dial knob 1513, the elastic member 170 drives the positioning projection 1519 to be inserted into the positioning groove 1103. The positioning protrusion 1519 cooperates with the positioning groove 1103 to prevent the dial 1513 from rotating the gear portion 153 again to prevent the first locking portion 1313 from being disengaged from the slot 2111 of the mounting head 211 in the first direction X and to prevent the second locking portion 1333 from being disengaged from the slot 2111 of the mounting head 211 in the first direction X.

The mounting mechanism 200 and the locking mechanism 100 in such an electrical apparatus can be disassembled using the following manner:

pressing the dial knob 1513 causes the positioning projection 1519 to disengage from the positioning groove 1103. Twisting the toggle 1513, the two sets of gear portions 153 move in synchronism. In each set of gear portions 153, the main gear 1531 rotates the first driven wheel 1533 and the second driven wheel 1535 about opposite rotational directions. The first and second rack portions 1311, 1331 move toward each other in the first direction X such that the first locking portion 1313 disengages from the first recessed slot 111 in the first direction X and the second locking portion 1333 disengages from the second recessed slot 117 in the first direction X. When the first locking portion 1313 is disengaged from the corresponding slot 2111 of the mounting head 211, the engagement of the mounting head 211 with the first locking portion 1313 is released. When the second locking portion 1333 is disengaged from the corresponding slot 2111 of the mounting head 211, the engagement of the mounting head 211 with the second locking portion 1333 is released. Releasing the dial knob 1513, the elastic member 170 drives the positioning projection 1519 to be inserted into the positioning groove 1103. The positioning protrusion 1519 cooperates with the positioning groove 1103 to prevent the toggle 1513 from driving the gear portion 153 to rotate again, to prevent the reinsertion of the first locking portion 1313 into the first recess 111 from affecting the insertion of the mounting head 211 next time, and to prevent the reinsertion of the second locking portion 1333 into the second recess 117 from affecting the insertion of the mounting head 211 next time.
