[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-Figure 5 The utility model provides a technical solution: a safety lock device for a lighter, comprising a lighter body 1 and a lighter installation chamber 10 arranged on the lighter body 1, a corresponding lighter is installed in the lighter installation chamber 10, the lighter is abutted between the lighter installation chamber 10 and the bottom surface of the pressing protrusion 2, and the lighter body 1 and the lighter in the lighter body 1 are existing conventional technologies, which will not be described in detail here;
[0026] A plurality of arc-shaped holes 11 communicating with the outside are arranged on the outer wall of the lighter installation chamber 10, and the upper and lower hole walls of the arc-shaped hole 11 are rotatably connected to the limit knob 3 through a rotating shaft 30, and an alignment hole 31 is arranged on the side of the limit knob 3, and a pressing protrusion 2 is slidably connected in the lighter installation chamber 10, and a handle plate 20 is fixedly installed on the top of the pressing protrusion 2, and the handle plate 20 is used for the pressing operation of the thumb; a vertical rod 21 arranged in a vertical shape is fixedly installed on the bottom surface of the pressing protrusion 2, and a sliding protrusion 211 is fixedly installed on the side of the vertical rod 21, and the sliding protrusion 211 passes through the alignment hole 31 and is slidably connected between the alignment hole 31, and the sliding protrusion 211 can slide down only when the sliding protrusion 211 is aligned with the alignment hole 31, and at this time, the pressing protrusion 2 can be pressed down to complete the ignition operation, thereby achieving the effect of safety locking and protection.
[0027] In this embodiment, a plurality of vertically arranged guide posts 22 are fixedly installed on the bottom surface of the pressing protrusion 2, and a plurality of vertically arranged guide sleeves 23 are fixedly installed on the bottom wall of the lighter mounting chamber 10. The guide sleeves 23 are sleeved on the guide posts 22 and are slidably connected with the guide posts 22. The sizes of the guide sleeves 23 and the guide posts 22 are matched, so that the sliding of the guide sleeves 23 on the guide posts 22 is more stable, and at the same time, it also ensures that the pressing protrusion 2 is pressed down more stably and smoothly.
[0028] Specifically, shaft holes 12 are provided on the bottom wall and the top wall of the arc-shaped hole 11 , and the rotating shaft 30 is located in the shaft hole 12 and is rotatably connected to the shaft hole 12 .
[0029] Furthermore, a slot 121 is provided on the hole wall of the shaft hole 12, and a boss 13 is slidably connected in the slot 121. A locking ball 131 is fixedly installed on the front end of the boss 13, and a spring 14 is fixedly installed between the rear end of the boss 13 and the slot wall of the slot 121. A plurality of arc chambers 301 arranged in a ring shape with equal intervals are provided on the annular side surface of the rotating shaft 30. The locking ball 131 is snap-fitted with the arc chamber 301, so that the rotating shaft 30 and the limit knob 3 will not rotate easily.
[0030] In addition, the arc-shaped chamber 301 and the locking ball 131 are both smaller than half of a sphere, and the size of the locking ball 131 is adapted to the size of the arc-shaped chamber 301 , which facilitates the locking ball 131 to be stably locked into the arc-shaped chamber 301 .
[0031] It is worth mentioning that a plurality of text marking areas 32 marked with text logos are provided on the annular side surface of the limit knob 3, wherein one of the text marking areas 32 and the alignment hole 31 are located on opposite sides of the limit knob 3, and the numbers marked on the text marking area 32 are the corresponding passwords, so that after turning the limit knob 3, it is easy to understand the position of the alignment hole 31 through the numbers in the corresponding text marking area 32.
[0032] It is worth noting that the width of the lower sliding protrusion 211 is smaller than the width of the alignment hole 31 , so that the lower sliding protrusion 211 can pass through the alignment hole 31 more smoothly.
[0033] When the safety lock device of the lighter of the utility model is used, the limit knob 3 is rotated according to the number on the side of the text mark area 32 facing the face of the person until the corresponding number is in the correct position. At this time, as the limit knob 3 is rotated, the alignment hole 31 is just below the downward sliding protrusion 211. After pressing the downward pressing protrusion 2, the downward sliding protrusion 211 passes through the alignment hole 31 and the ignition operation can be performed normally.
[0034] When locking, the limit knob 3 is rotated until the alignment hole 31 is no longer under the downward sliding protrusion 211. At this time, after pressing the downward pressing protrusion 2, the downward sliding protrusion 211 will abut against the upper surface of the limit knob 3, blocking the downward sliding protrusion 211, making the ignition unsuccessful.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
