Description

Technical Field

[0001] This utility model relates to the field of nail gun technology, and in particular to a trigger assembly, a control device, and a nail gun. Background Technology

[0002] In current lithium-ion nail gun designs, the core mechanism relies on trigger operation to fire the nail gun. Specifically, when the user pulls the trigger, the rotation of the trigger causes the trigger contact part to engage the button in the micro switch, thus firing the nail.

[0003] However, in actual operation, when the trigger contact contacts the button of the micro switch and triggers the nail gun to fire, the vibration generated by the lithium-ion nail gun during operation is directly transmitted to the entire micro switch because the trigger contact has not yet disengaged from the button. This process may damage the internal structure of the micro switch, especially considering the high-frequency vibration and impact force generated by the nail gun during operation. In the long run, this will not only affect the lifespan of the micro switch but may also increase maintenance costs and equipment failure rate, and reduce user experience. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a trigger assembly, a control device, and a nail gun, which can solve the problem that when the trigger and button are not disengaged or not completely disengaged during the firing process of the nail gun, the vibration of the gun body is transmitted to the micro switch, resulting in a reduction in the service life of the micro switch.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A trigger assembly includes a trigger and a button, the trigger having a contact portion for contacting the button, the contact portion being connected to a cushioning structure for absorbing vibration when the contact between the trigger and the button is subjected to vibration.

[0007] Furthermore, the trigger is slidably connected to a push rod, the end of the push rod facing the button is the contact part, and the buffer structure is an elastic element, which is disposed between the push rod and the trigger.

[0008] Furthermore, the trigger is provided with an assembly hole, the push rod and the elastic element (4) are inserted into the assembly hole in sequence, and the contact part is located outside the assembly hole. The elastic element is provided inside the assembly hole, and one end of the elastic element abuts against the bottom wall of the assembly hole, and the other end abuts against the push rod.

[0009] Furthermore, the push rod is provided with a sliding groove, and the trigger is provided with a fixing pin. The fixing pin passes through the sliding groove so that the push rod can be limited within the trigger by the sliding groove.

[0010] Furthermore, the push rod has a limiting structure at one end facing the elastic member, and the elastic member is engaged with the limiting structure.

[0011] Furthermore, the limiting structure is a limiting hole, and one end of the elastic element facing the limiting structure is disposed in the limiting hole.

[0012] This utility model also provides a control device, including:

[0013] micro switch;

[0014] case;

[0015] The aforementioned trigger assembly;

[0016] The button is a pin-shaped button of the micro switch. The micro switch is fixedly mounted inside the housing, and the trigger is movably mounted on the housing so that the contact part contacts the pin-shaped button after the trigger moves.

[0017] Furthermore, it also includes a flexible pad that is attached to the micro switch.

[0018] Furthermore, two flexible pads are provided, and the two flexible pads are respectively provided on opposite sides of the micro switch.

[0019] This utility model also provides a nail gun, including the trigger assembly described above, or the control device described above.

[0020] In summary, the trigger assembly, control device, and nail gun provided by this utility model have the following technical effects:

[0021] 1. By using a buffer structure connected to the contact part of the trigger, the impact force transmitted to the micro switch due to the vibration of the gun body can be effectively absorbed during the period after the nail gun is fired but before the trigger is released from the button. This protects the micro switch from damage, reduces or even prevents it from being damaged, reduces micro switch failures caused by vibration, improves the reliability and service life of the entire control device, and reduces maintenance costs and equipment failure rate.

[0022] 2. By reducing the likelihood of equipment failure, the user experience is significantly improved. Users no longer need to frequently repair or replace damaged parts, ensuring continuity and efficiency of work. Attached Figure Description

[0030] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0031] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] See Figures 1-6The present invention discloses a trigger assembly, including a trigger 1 and a button 21. The trigger 1 has a contact portion 31 for contacting the button 21. The contact portion 31 is connected to a buffer structure to absorb vibration when the trigger 1 and the button 21 are vibrated during contact.

[0035] Specifically, the trigger 1 has a contact portion 31 for contacting the button 21. The contact portion 31 is connected to a buffer structure, the main function of which is to effectively absorb vibrations when the trigger 1 and the button 21 are in contact and subjected to vibrations. This reduces the damage to internal components (especially the micro switch 2) caused by vibrations generated during the operation of the nail gun.

[0036] Optionally, the buffer structure can be made of springs, sheet metal, rubber, or flexible polymer materials to form elastic pads, sponges, or other structures with vibration absorption capabilities; no limitation is made here. The buffer structure can be positioned directly between the contact surfaces of the contact part 31 and the button 21, or it can be positioned on the side of the contact part 31 away from the button 21, as long as it can absorb a certain amount of vibration transmitted to the button 21 when the contact part 31 contacts the button 21.

[0037] In some embodiments, the trigger 1 is slidably connected to a push rod 3, the end of the push rod 3 facing the button 21 is the contact portion 31, and the buffer structure is an elastic element 4, which is disposed at the end opposite to the contact portion 31 of the push rod 3.

[0038] Specifically, the trigger 1 is slidably connected to a push rod 3, meaning the push rod 3 slides on the trigger 1. The end of the push rod 3 facing the button 21 is the contact portion 31, and the buffer structure is an elastic element 4, located at the end opposite the contact portion 31 of the push rod 3. When the trigger 1 is pulled to fire, the trigger 1 and the push rod 3 move synchronously toward the button 21, and the push rod 3 contacts the button 21, completing the firing. At the same time, the push rod 3 remains in contact with the button 21, and the vibration of the nail gun is transmitted to the button 21 after passing through the trigger 1 and the push rod 3. At this time, relative to the hard contact with the button 21, the push rod 3 has a certain amount of room for contraction, and the push rod 3 slides away from the button 21, while simultaneously compressing the elastic element 4 to absorb vibration and impact. After the above vibration absorption is completed, as the trigger 1 disengages from the button 21, the elastic element 4 pushes the push rod 3 to reset, completing the entire firing and resetting process.

[0039] It should be noted that the force required to press button 21 is generally much less than the stiffness coefficient of elastic element 3. Therefore, when button 21 is pressed, elastic element 3 will only contract slightly or even slightly, and there is still a large contraction space to provide space for the sliding of push rod 3 when subjected to vibration.

[0040] In some embodiments, the trigger 1 is provided with a mounting hole 11, the push rod 3 is slidably disposed in the mounting hole 11, and the contact portion 31 is located outside the mounting hole 11. The elastic member 4 is disposed inside the mounting hole 11, and one end of the elastic member 4 abuts against the bottom wall of the mounting hole 11, and the other end abuts against the push rod 3.

[0041] Specifically, the trigger 1 has a mounting hole 11. This mounting hole 11 provides a mounting space and sliding track for the push rod 3, allowing it to move along the direction of the mounting hole 11. The push rod 3 is slidably disposed within the mounting hole 11, with one end of the contact portion 31 located outside the mounting hole 11, ensuring direct contact with the button 21 on the micro switch 2. An elastic element 4 is installed inside the mounting hole 11. One end of the elastic element abuts against the bottom wall of the mounting hole 11, and the other end abuts against the push rod 3. This allows the elastic element 4 to effectively absorb vibrations generated when the push rod 3 moves synchronously with the trigger 1 and contacts the button 21, thus protecting the micro switch 2. Furthermore, the elastic element 4 also facilitates the reset of the push rod 3.

[0042] In some embodiments, the push rod 3 is provided with a slide groove 32, and the trigger 1 is provided with a fixing pin 5. The fixing pin 5 is disposed through the slide groove 32 so that the push rod 3 can slide along the direction of the slide groove 32.

[0043] Specifically, a groove 32 is provided on the push rod 3. This groove 32 provides a guide path for the fixing pin 5, allowing the push rod 3 to move linearly only along the direction of the groove 32. The position and length of the groove 32 are determined according to actual needs to ensure that the push rod 3 has sufficient range of motion during operation, i.e., sufficient sliding range during vibration absorption. A fixing pin 5 is provided on the trigger 1. This fixing pin 5 passes through the groove 32 on the push rod 3. Through the above structure, the fixing pin 5 and the groove 32 cooperate with each other, restricting the direction of movement of the push rod 3 while allowing it to slide freely along the direction of the groove 32.

[0044] Based on the structure of the trigger 1 with the mounting hole 11, the cooperation between the slide 32 and the fixing pin 5 can prevent the push rod 3 from coming out of the mounting hole 11, making it convenient for the trigger 1 to be assembled in a modular manner.

[0045] In some embodiments, the push rod 3 has a limiting structure at one end facing the elastic member 4, and the elastic member 4 is engaged with the limiting structure.

[0046] Specifically, a limiting structure is provided at the end of the push rod 3 facing the elastic element 4. One end of the elastic element 4 is engaged with the limiting structure, thereby preventing the contact position and contact angle between the elastic element 4 and the push rod 3 from shifting during compression and reset, thus ensuring the reliability of the cooperation between the push rod 3 and the elastic element 4. Furthermore, the limiting structure also facilitates the installation and replacement of the elastic element 4, helping to reduce maintenance costs and time.

[0047] Alternatively, the limiting structure can be a limiting hole 33 or a limiting post. Based on the structure of the elastic element 4 using a spring, the spring can be sleeved on the limiting post, thereby ensuring the stability of the relative position and relative angle between the elastic element 4 and the push rod 3, and ensuring the reliability of the cooperation between the push rod 3 and the elastic element 4.

[0048] In some embodiments, the limiting structure is a limiting hole 33, and one end of the elastic member 4 facing the limiting structure is disposed in the limiting hole 33.

[0049] Specifically, a limiting hole 33 is provided at the end of the push rod 3 facing the elastic element 4. The limiting hole 33 is used to fix the elastic element 4, and its size and shape can be freely selected according to the specific specifications of the elastic element 4 used, so as to ensure the stability of the relative position and relative angle between the elastic element 4 and the push rod 3 during the compression and reset process of the elastic element 4.

[0050] In some embodiments, to facilitate the reset of the trigger 1, a trigger spring 7 is provided in the direction of the trigger's movement during the firing process, for reset after the trigger 1 is pulled.

[0051] This utility model also provides a control device, including a micro switch 2, a housing, and the trigger assembly described above. The button 21 is a pin-shaped button of the micro switch 2. The micro switch 2 is fixedly mounted inside the housing, and the trigger 1 is movably mounted on the housing so that the contact part 31 contacts the pin-shaped button after the trigger 1 moves.

[0052] Specifically, the micro switch 2 receives signals from the trigger assembly and triggers the nail gun to operate based on these signals. The button 21 is a pin-shaped button on the micro switch 2. The trigger assembly includes components such as the trigger 1, push rod 3, and elastic element 4. The micro switch 2 is fixedly mounted inside the housing, and the trigger 1 is movably mounted on the housing so that the contact portion 31 contacts the pin-shaped button after the trigger 1 moves. Specifically, the movable connection between the trigger 1 and the housing can be either a sliding connection or a rotating connection, providing the trigger 1 with a structural basis for moving towards the button 2.

[0053] In some embodiments, the control device further includes a flexible pad 6, which is in contact with the micro switch 2.

[0054] Specifically, the flexible pad 6 is fitted into the micro switch 2. The flexible pad 6 is made of a material with good shock absorption properties, such as rubber or a polymer with a high damping coefficient. These materials can effectively absorb impact energy when the nail gun is accidentally dropped, reducing the vibration transmitted to the micro switch 2.

[0055] Optionally, the specific contact position of the flexible pad 6 with the micro switch 2 can be set according to specific needs. It should be noted that as long as the flexible pad 6 is in contact with the micro switch 2, it will have the effect of absorbing vibration. The specific contact area can be freely set according to needs.

[0056] In some embodiments, two flexible pads 6 are provided, and the two flexible pads 6 are respectively provided on opposite sides of the micro switch 2.

[0057] Specifically, two flexible pads 6 are respectively located on opposite sides of the micro switch 2, that is, the micro switch 2 is located between the two flexible pads 6. This arrangement ensures that the micro switch 2 can be uniformly protected in multiple directions.

[0058] This utility model also provides a nail gun, including the trigger assembly described above.

[0059] Optionally, trigger 1 is rotatably connected to the nail gun so that when trigger 1 is pulled, it rotates to contact button 21, achieving a firing effect. The trigger assembly also includes a buffer structure that absorbs vibrations transmitted to button 21 when trigger 1 contacts button 21, thereby improving the service life of button 21. The housing can be the housing at the nail gun handle.

[0060] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
