The utility model will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 8, the present embodiment provides a quick-acting switch mechanism including a switch body 10 and a drive assisting mechanism 20; the drive support 20 has two oppositely disposed connecting webs 21. The two connecting sheets 21 are sleeved on the switch body 10 and hinged with the switch body; specifically, switch body 10 is gone up the arch and is had articulated post 13, connection piece 21 is provided with hinge hole 211, and connection piece 21 realizes articulatedly through the cooperation of hinge hole 211 with articulated post 13.

The switch body 10 further extends with two retaining walls 14, and the two retaining walls 14 are respectively located at the outer sides of the two connecting pieces 21, as shown in fig. 2. The retaining wall 14 can effectively limit the outward deformation of the connecting sheet 21 to separate from the hinge connection with the switch body 10, so that the quick-acting switch mechanism has a more stable structure and more reliable action.

Specifically, in this embodiment, the hinge hole 211 is formed in the connecting piece 21, and the hinge hole is matched with the hinge post 13 on the switch body 10 to realize hinge, so that the structure is simple. Preferably, the hinge post 13 is sleeved with a bearing bush 15, and the rotation hole 211 of the connecting piece 21 is connected with the bearing bush 15 in a matching manner. The structure of the bearing bush 15 is added, and the bearing bush 15 is used for avoiding the rotation clamping caused by abrasion due to the direct contact between the driving auxiliary mechanism 20 and the hinge column 13; the bearing bush 15 also serves to reinforce the structural strength of the hinge post 13 and prevent the hinge post 13 from being broken due to external impact. Of course, in other embodiments, the structure of the bearing bush 15 may not be additionally provided; alternatively, the hinge structure between the connecting piece 21 and the switch body 10 is not limited thereto, such as a hinge post disposed on the connecting piece 21, a hinge hole disposed on the switch body 10, and the like.

Further, in the present embodiment, a hinge seat 12 for hinge-fitting with the driving assistance mechanism 20 is formed on the switch body 10, as shown in fig. 4 and 5, the hinge seat 12 has two opposite side surfaces 121 and an end surface 122 located between the two side surfaces 121 and facing outward; the hinge post 13 protrudes from two side surfaces 121; the two connecting pieces 21 are sleeved on the hinge base 12 of the switch body 10 and are matched with the hinge column 13 to form a hinge. The retaining wall 14 is positioned outside the side surface 121 of the hinge seat 12; when the hinge is matched, the connecting piece 21 is positioned between the side surface 121 of the hinge seat 12 and the retaining wall 14, and the retaining wall 14 limits the outward deformation of the connecting piece 21.

More specifically, the side surface 121 of the hinge base 12 is recessed in the side surface of the switch body 10, and the retaining wall 14 is located outside the side surface 121 of the hinge base 12 and is flush with the side surface of the switch body 10. With this arrangement, the size of the switch body can be maintained without increasing the volume of the switch body 10.

Meanwhile, for better assembly, a first inclined guide surface 123 is formed between the end surface 122 and the side surface 121 of the hinge base 12, and a second inclined guide surface 131 is formed on the hinge post 13 toward the end surface 122. When assembled, the two connecting pieces 21 are laterally inserted from the end surface 122 of the hinge base 12, i.e., from the left to the right in the orientation of fig. 5, and the inclined guide surface 123 between the end surface 122 and the side surface 121 serves as a good guide. After the step of sleeving, the connecting piece 21 is sleeved by the guide of the inclined guide surface 131 on the hinge column 13, so that the hinge column 13 is in sleeve fit with the hinge hole 211, and the hinge is realized. So set up, assembly operation is simple. Of course, in other embodiments, this is not limiting.

Further, in order to prevent the driving assistance mechanism 20 from being dislocated due to an excessive stroke when the driving assistance mechanism 20 is reversed and returned (i.e., when the driving assistance mechanism is returned counterclockwise as shown in fig. 7), the driving assistance mechanism 20 and the switch body 10 are provided with a limiting structure to limit the maximum reversing distance of the driving assistance mechanism 20. Specifically, in this embodiment, the limiting structure is: as shown in fig. 8, a first limit step 212 is formed on the connecting piece 21, a second limit step 16 corresponding to the first limit step 212 is provided on the switch body 10, and the connecting piece 21 limits the distance of the driving assistance mechanism 20 away from the push rod 11 of the switch body 10 by the first limit step 212 abutting against the second limit step 16. That is, when the driving assisting mechanism 20 is turned over counterclockwise and returned to a certain position, the first limiting step 212 abuts against the second limiting step 16, so that the driving assisting mechanism 20 cannot be turned over counterclockwise any more, thereby achieving the limiting. Simple structure, it is spacing stable. Of course, in other embodiments, other structures may be used instead of the limiting structure.

Specifically, in order to simplify the structure of the drive assisting mechanism 20, as shown in fig. 6, in the present embodiment, the drive assisting mechanism 20 has a sheet-shaped body 201, the sheet-shaped body 201 has a first end portion and a second end portion which are opposite to each other, and a middle position between the first end portion and the second end portion, and two connecting pieces 21 are located at the first end portion of the sheet-shaped body 201 and integrally connected with the sheet-shaped body 201; namely, the composite material is integrally bent by means of stamping and the like during preparation. The middle position of the sheet-shaped body 201 corresponds to the pushing rod 11 of the switch body 10, and as shown in fig. 9 and 10, the second end of the sheet-shaped body 201 forms a contact 22 for contacting with the external actuator 30. In operation, the external actuator 30 slides and abuts on the contact 22, and the external actuator 30 continues to slide to gradually press down the contact 22, so that the sheet-like body 201 swings clockwise, thereby pressing down the push rod 11 of the switch body 10, as shown in fig. 10, and further switching the state of the switch body 10. When the external actuator 30 is separated from the contact head 22 in a sliding manner, the push rod 11 of the switch body 10 rises and drives the sheet-shaped body 201 to reset, and in the resetting process of the sheet-shaped body 201, the first limiting step 212 and the second limiting step 16 are abutted and matched to realize limiting, so that dislocation caused by overlarge stroke is prevented.

The driving auxiliary mechanism 20 adopts a structure of a sheet-shaped body 201, only one part is needed, the operation of fixing and assembling such as riveting is not needed, and the assembling cost and the processing cost are reduced.

The contact head 22 is a circular arc contact head, so that the external actuator 30 can smoothly press the driving assisting mechanism 20, and the reinforcing ribs 221 are protruded on the contact head 22, so that the strength of the contact head 22 can be enhanced, and the external actuator 30 can be prevented from pressing and deforming. Specifically, in the present embodiment, the rib 221 is formed by pressing downward, that is, a concave portion is formed on the upper surface of the contact 22 by pressing, and the rib 221 protrudes from the lower surface of the contact 22. Of course, in other embodiments, the ribs 221 may also protrude from the upper surface of the contact 22; alternatively, the ribs 221 may be formed without stamping, i.e., the ribs 221 may protrude from the lower surface of the contact 22, and the like, while the upper surface remains flat.

Meanwhile, a reed 23 is arranged in the middle of the sheet-shaped body 201, the periphery of the reed 23 is abducted to form an abduction window 24, and the abduction window 24 enables the reed 23 to form a cantilever structure. The reed 23 corresponds to the push rod 11 of the switch body 10. With the spring plate 23, when the stroke of the external actuator 30 applied to the drive assisting mechanism 20 is too large, the spring plate 23 is deformed as shown in fig. 10, thereby providing a buffer to prevent the external actuator 30 from being continuously pressed and damaged.

Furthermore, the structure of the reed 23 and the abdicating window 24 at the middle position of the sheet-shaped body 201 is integrally formed by punching, so that the preparation is simple and convenient, and the efficiency is high.

Of course, in other embodiments, the structure of the drive assist mechanism 20 is not limited thereto.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
