Description

Technical Field

[0001] The utility model relates to the technical field of ignition needles, in particular to an ignition needle with position limiting self-tightening function. Background Art

[0002] The ignition pin on a gas stove acts as a ignition igniter. It ignites some of the gas flowing out of the vent hole and then feeds this fire source into the gas on the fire cap or main burner to ignite the gas. Existing household gas stove ignition pins are mostly fixed with clips or screws, which makes them inconvenient to disassemble and assemble, both the ignition pin and other accessories. In view of this, we have proposed an ignition pin with a limiter and self-tightening function. Utility Model Content

[0003] The purpose of the present utility model is to provide an ignition needle with limited self-tightening function to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides an ignition needle with limited self-tightening, comprising a shell, a fixing device provided on the outside of the shell, an adjustment device provided on the inside of the fixing device, the adjustment device comprising a plurality of second hinged seats, and a second hinged rod rotatably provided between two of the corresponding positions of the second hinged seats. When one of the second hinged rods moves, since the length of the second hinged rod is fixed and the second hinged rod is rotatably provided between the two second hinged rods, the other second hinged seat is moved.

[0005] A connecting plate is fixedly connected to one side of the second hinged seats, a connecting block is rotatably provided inside the connecting plate, and the connecting block passes through the connecting plate and is fixedly connected to an adjusting bolt.

[0006] The fixing device includes two fixing blocks, one side of which is fixedly connected to one side of the second hinge seat.

[0007] The fixing block is fixedly connected to a plurality of first hinge seats on one side close to the second hinge seat, a first hinge rod is rotatably provided inside the first hinge seat, the end of the first hinge rod is fixedly connected to a frame plate, and the adjusting bolt passes through the frame plate and extends out.

[0008] The shell includes a ceramic head, a slide groove is provided inside the ceramic head, an electrode needle is slidably provided inside the slide groove, a plurality of limit blocks are fixedly provided inside the slide groove, and a plurality of grooves matching the limit blocks are provided outside the electrode needle.

[0009] A plurality of rubber pads are arranged on the outside of the ceramic head, and the rubber pads are fixedly arranged on adjacent side surfaces of the two fixing blocks.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In this ignition needle with limited self-tightening, the connecting plate is moved by turning the adjusting bolt, and the position of one side of the fixed block is fixed by the first hinge seat and the first hinge rod. At the same time, the rotation connection between the second hinge rod and the two hinge seats allows the two fixed blocks to be opened or closed when the fixed block is pushed, which facilitates the installation or disassembly of the ceramic head and is easy to operate.

[0020] Example 1

[0021] See also Figures 1-4 As shown, this embodiment provides an ignition needle with limiting self-tightening, including a shell 1, a fixing device 2 is provided on the outside of the shell 1, and an adjusting device 3 is provided on the inside of the fixing device 2. The shell 1 includes a ceramic head 11, a slide groove 12 is provided inside the ceramic head 11, an electrode needle 13 is slidably provided on the inside of the slide groove 12, a plurality of limiting blocks 14 are fixedly provided on the inside of the slide groove 12, and a plurality of grooves matching the limiting blocks 14 are provided on the outside of the electrode needle 13. When the electrode needle 13 is installed, the electrode needle 13 is first inserted into the slide groove 12 and pressed downward to make the limiting blocks 14 snap into the corresponding grooves. If the height of the electrode needle 13 needs to be adjusted, it can be done by snapping limiting blocks 14 of different heights into the grooves, which effectively solves the problem of displacement of the electrode needle 13 during assembly. The limiting function further improves the fault tolerance of the process, reduces the use of tooling and fixtures, improves product quality, and reduces the defective rate.

[0022] The adjusting device 3 includes a plurality of second hinged seats 31, and a second hinged rod 32 is rotatably arranged between two second hinged seats 31 at corresponding positions. When one of the second hinged rods 32 moves, since the length of the second hinged rod 32 is fixed and the second hinged rod 32 is rotatably arranged between the two second hinged rods 32, the other second hinged seat 31 is moved. A connecting plate 33 is fixedly connected to one side of one of the second hinged seats 31, and a connecting block 34 is rotatably arranged inside the connecting plate 33. The connecting block 34 passes through the connecting plate 33 and is fixedly connected with an adjusting bolt 35. The position of the connecting plate 33 is adjusted by twisting the adjusting bolt 35, so that the two second hinged seats 31 push the fixed block 21 to move.

[0023] The fixing device 2 includes two fixing blocks 21, one side of the fixing block 21 is fixedly connected to one side of the second hinge seat 31, and the side of the fixing block 21 close to the second hinge seat 31 is fixedly connected to multiple first hinge seats 22, and a first hinge rod 23 is rotatably provided on the inner side of the first hinge seat 22, and the end of the first hinge rod 23 is fixedly connected to the frame plate 24, and the adjusting bolt 35 passes through the frame plate 24 and extends out. When the second hinge seat 31 pushes the fixing block 21 to move, the position of one end of the fixing block 21 is fixed by the rotation between the first hinge seat 22 and the first hinge rod 23, so that the fixing block 21 rotates with the first hinge rod 23 as the center of the circle. When the connecting block 34 moves toward the fixing block 21, the two fixing blocks 21 are opened, and the ceramic head 11 is placed between the two fixing blocks 21, and then the adjusting bolt 35 is rotated to make the connecting block 34 move toward the frame plate 24, so that the two fixing blocks 21 are closed, thereby fixing the ceramic head 11.

[0024] A plurality of rubber pads 25 are provided on the outside of the ceramic head 11. The rubber pads 25 are fixed on the adjacent sides of the two fixing blocks 21. When the fixing blocks 21 fix the ceramic head 11, the setting of the plurality of rubber pads 25 prevents the fixing blocks 21 from excessively pressing the ceramic head 11 and causing damage to the ceramic head 11.

[0025] When using the ignition needle with limiting self-tightening of this embodiment, the user first inserts the electrode needle 13 into the slide groove 12 and presses it downward, so that the limiting block 14 is stuck in the groove provided on the electrode needle 13, thereby fixing the position of the electrode needle 13 to prevent the electrode needle 13 from shifting, and then twists the adjusting bolt 35 to move the connecting plate 33 toward the fixed block 21, and fixes the position of one end of the fixed block 21 through the first hinge seat 22, cooperates with the rotation connection between the second hinge rod 32 and the two second hinge seats 31, opens the two fixed blocks 21, and then puts the ceramic head 11 in, twists the adjusting bolt 35 to move the connecting plate 33 toward the frame plate 24, so that the two fixed blocks 21 clamp the ceramic head 11.
