Description

Technical Field

[0001] This utility model relates to the field of switch trigger technology, and in particular to a switch trigger that prevents accidental triggering. Background Technology

[0002] In order to facilitate user operation, some power tools on the market have a push-button switch on the grip part (2). When the switch trigger is pressed, the switch is triggered, so that the head part (1) is energized and starts to work; when the switch trigger is released, the switch is disconnected, so that the head part (1) is de-energized and stops working.

[0003] In actual use, in order to facilitate users to hold the gripping part (2) from multiple angles, the head part (1) and the gripping part (2) are designed to be rotatable. However, during rotation, users are very likely to accidentally touch the switch trigger, which will cause the head part (1) to be directly connected, posing a safety hazard.

[0004] To address this, a switch trigger designed to prevent accidental activation is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a switch trigger that prevents accidental triggering, thereby solving the problems mentioned in the background art.

[0010] As a preferred technical solution, the locking component includes a second positioning pin fixedly connected to one side of the trigger body cavity. A first button is rotatably sleeved on the surface of the second positioning pin. The bottom of the first button extends through to the bottom of the trigger body, and a boss is fixedly connected to the top of the first button. The top of the boss extends through to the top of the trigger body and can contact the holding component.

[0011] As a preferred technical solution, a first spring is fixedly connected between the first button and the trigger body.

[0012] As a preferred technical solution, the limiting component includes a limiting rib slidably connected to one side of the outer surface of the bracket. A second button is fixedly connected to the top of the limiting rib, and the second button is located above the bracket. The bottom of the limiting rib is located above the trigger body. A baffle that works in conjunction with the limiting rib is fixedly connected to the top of the trigger body away from the first positioning pin.

[0016] This utility model has at least the following beneficial effects:

[0017] This application, by adding a bracket and a limiting component to the gripping component, allows the user to press the limiting component before rotating the gripping component. The limiting component restricts the switch trigger body, preventing it from reaching the switch's trigger stroke and thus ensuring the head unit cannot start normally. This effectively prevents the user from accidentally triggering the locking component and starting the head unit while rotating the gripping component, providing a safety protection function. After the gripping component has finished rotating, releasing the limiting component allows it to reset and no longer restricts the switch trigger body, facilitating the normal starting and use of the head unit.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5This embodiment provides a switch trigger to prevent accidental triggering, including a switch 100 and a switch trigger body 200. The switch 100 and the switch trigger body 200 are respectively disposed on the gripping member 2. The switch 100 is located above the switch trigger body 200. The switch trigger body 200 is used to trigger or release the switch 100. The switch trigger body 200 is provided with a locking member 300 for locking or unlocking the switch trigger body 200. The locking member 300 is movably connected to the gripping member 2. The switch 100 is provided with a bracket 400 on the side near the head member 1. The bracket 400 is disposed on the gripping member 2. The bracket 400 is provided with a limiting member 500 for limiting or releasing the switch trigger body 200. The bracket 400 is used to provide a mounting base for the limiting member 500.

[0026] The gripping component 2 includes a left handle 21 and a right handle 22, forming a receiving cavity between them. The switch 100 and the bracket 400 are both fixedly installed within this cavity. A connecting female 23 is integrally formed on the side of both the left handle 21 and the right handle 22 facing the head component 1. A connecting male 11, which mates with the connecting female 23, is fixedly connected to one side of the head component 1. The surface of the connecting male 11 is rotatably connected to the inner wall of the connecting female 23. The gripping component 2 allows for the connection of the switch 100 and the bracket 400. The trigger body 200, the deadbolt 300, the bracket 400, and the limiting component 500 provide a mounting base. The inner sides of the left handle 21 and the right handle 22 are respectively provided with a first through hole 24 for the trigger body 220 to pass through. The first through hole 24 communicates with the receiving cavity. The top of the left handle 21 and the right handle 22 are respectively provided with a second through hole 25 for the second button 520 to pass through. The second through hole 25 communicates with the receiving cavity. The inner cavities of the left handle 21 and the right handle 22 are both integrally formed with a protrusion 26 that cooperates with the boss 330.

[0027] The switch trigger body 200 includes a first positioning pin 210 located inside the gripping component 2 and below the switch 100. The surface of the first positioning pin 210 is rotatably sleeved with the trigger body 220 via a rotating shaft. The bottom of the trigger body 220 extends to the outside of the gripping component 2. The anti-locking component 300 is located on the side of the trigger body 220 away from the first positioning pin 210. By pressing the trigger body 220, the trigger body 220 can rotate upward around the first positioning pin 210 as the axis, thereby triggering the switch 100 and starting the operation of the head component 1.

[0028] The locking component 300 includes a second positioning pin 310 fixedly connected to one side of the inner cavity of the trigger body 220. A first button 320 is rotatably sleeved on the surface of the second positioning pin 310 via a rotating shaft. The bottom of the first button 320 extends through to the bottom of the trigger body 220, and a boss 330 is fixedly connected to the top of the first button 320. The top of the boss 330 extends through to the top of the trigger body 220 and into the receiving cavity, where it can contact the protrusion 26. When the switch trigger body 200 is directly pressed, the top of the boss 330 contacts the protrusion 26. The protrusion 26 makes contact, thereby locking the switch trigger body 200. When the deadbolt 300 is pressed, the first button 320 can rotate around the second positioning pin 310, causing the first button 320 to drive the boss 330 to rotate synchronously, thereby separating the boss 330 from the protrusion 26, thus completing the unlocking operation of the switch trigger body 200. At this time, if the deadbolt 300 is pressed again, the switch trigger body 200 can be moved synchronously, so that the switch trigger body 200 triggers the switch 100.

[0029] A first spring 340 is fixedly connected between the first button 320 and the trigger body 220. The elastic force of the first spring 340 can automatically reset the first button 320.

[0030] The limiting component 500 includes a limiting rib 510 slidably connected to one side of the outer surface of the bracket 400. A second button 520 is fixedly connected to the top of the limiting rib 510, which is located above the bracket 400. The bottom of the limiting rib 510 is located above the trigger body 220. A baffle 600 that works with the limiting rib 510 is fixedly connected to the side of the top of the trigger body 220 away from the first positioning pin 210. The distances between the limiting rib 510 and the baffle 600, and between the second button 520 and the bracket 400 are equal. When the second button 520 is pressed down to the maximum extent, the limiting rib 510 can be moved down to the maximum extent on one side of the bracket 400, so that the bottom of the limiting rib 510 can contact the baffle 600, thereby restricting the operation of the switch trigger body 200. At this time, pressing the locking component 300 will prevent the switch trigger body 200 from triggering the switch 100.

[0031] The bottom of the inner wall of the bracket 400 is fixedly connected to a second spring 530, and the top of the second spring 530 is fixedly connected to the bottom of the second button 520. Through the elastic force of the second spring 530, the second button 520 can be automatically reset.

[0032] The bottom of the second button 520 is fixedly connected to a connecting rib 540 that is parallel to the limiting rib 510. The connecting rib 540 is slidably connected to the other side of the outer surface of the bracket 400. A protruding rib 550 is fixedly connected to the side of the connecting rib 540 away from the limiting rib 510. One side of the protruding rib 550 extends into the inner cavity of the connecting female seat 23 and contacts the connecting male seat 11. Through the combined use of the connecting male seat 11, the connecting female seat 23, the connecting rib 540 and the protruding rib 550, the second button 520 can be limited, effectively preventing the second button 520 and the limiting rib 510 from moving excessively and detaching from the holding component 2.

[0033] Among them, the side of the limiting rib 510 away from the connecting rib 540 is fixedly connected to the reinforcing rib 560. The top of the reinforcing rib 560 is fixedly connected to the bottom of the second button 520. The reinforcing rib 560 can reinforce the limiting rib 510, which helps to improve the firmness of the connection between the second button 520 and the limiting rib 510.

[0034] The working principle of this utility model is as follows: When it is necessary to rotate the gripping component 2, first press down on the second button 520, so that the second button 520 drives the limiting rib 510, reinforcing rib 560, connecting rib 540 and protruding rib 550 to move downward simultaneously. The second button 520 compresses the second spring 530, causing the second spring 530 to contract under force until the second button 520 contacts the top of the bracket 400. At this time, the second button 520 and the limiting rib 510 both move down to their maximum extent. At this time, the bottom of the limiting rib 510 contacts the baffle 600, which can restrict the switch trigger body 200, so that the switch trigger body 200 cannot reach the trigger stroke of the switch 100, thereby ensuring that the head component 1 cannot start normally. This effectively prevents the user from accidentally triggering the locking component 300 and starting the head component 1 when rotating the gripping component 2, thus playing a safety protection role. After the gripping component 2 has been rotated, release the second button 520. Button 520, through the elastic restoring force of the second spring 530, drives the second button 520, limiting rib 510, reinforcing rib 560, connecting rib 540 and protruding rib 550 to move upward and reset synchronously, so as not to restrict the switch trigger body 200. By pressing the first button 320, the first button 320 rotates around the second positioning pin 310 as the axis. The first button 320 drives the boss 330 to rotate synchronously. The first button 320 squeezes the first spring 340, causing the first spring 340 to contract under force until the first button 320 rotates to the maximum extent and the boss 330 is completely away from the protrusion 26, thus unlocking the switch trigger body 200. Continuing to press the first button 320 causes the first button 320 to drive the trigger body 220 to rotate around the first positioning pin 210 as the axis towards the switch 100, thereby triggering the switch 100 and starting the operation of the head component 1.

[0035] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
