Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to ignition needle technical field, concretely is a kind of ignition needle adjusting device. BACKGROUND
[0002] Ignition needle is generally installed on the stove using the thread on needle body to cooperate two nuts, nut is tightened and fixed needle body in stove installation hole inside and outside. Because the installation height of ignition needle needs to keep certain position, too high, too low all influence to fire, so before specific installation, the installation height of previous ignition needle needs to be adjusted, because the upper nut is not fixed, so loose easy displacement, affect height adjustment, and when disassembling, the lower nut also needs to be removed from the bottom of stove, it is more cumbersome. UTILITARY MODEL CONTENT
[0003] The utility model aims at providing a kind of ignition needle adjusting device, to solve the problem that the upper nut is not fixed in the background art described above, so loose easy displacement, affect height adjustment, and when disassembling, the lower nut also needs to be removed from the bottom of stove, it is more cumbersome.
[0004] To achieve the above object, the utility model provides the following technical scheme:
[0005] A kind of ignition needle adjusting device, including needle body, the convex point is formed in the protruding of the outer surface of needle body, upper sleeve body and lower sleeve body are sleeved and installed on needle body, the upper sleeve body and lower sleeve body structure are same, the upper sleeve body includes ring body and pressing sheet, and the pressing sheet is arranged in the inside of ring body around axis.
[0006] As further description of the above technical scheme:
[0007] The convex point is arranged on the ceramic sleeve or metal sleeve of needle body.
[0008] As further description of the above technical scheme:
[0009] The interval between the convex point is 4mm-5mm.
[0010] As further description of the above technical scheme:
[0011] The pressing sheet is elastic metal sheet.
[0012] As further description of the above technical scheme:
[0013] The pressing sheet is arranged in the clockwise or counterclockwise oblique direction.
[0014] As further description of the above technical scheme:
[0015] The number of pressing sheet is three to six.
[0016] Compared with the prior art, the ignition needle adjusting device has the following beneficial effects:
[0017] 1. In the utility model, the convex points are designed on the needle body, and the stability of the upper sleeve body and the lower sleeve body is further increased by the convex points;
[0018] 2. In the utility model, the upper sleeve body and the lower sleeve body can be displaced on the needle body to adjust the position, and after adjustment, the lower sleeve body is not loose and slides downward, and when the needle body is taken out, the lower sleeve body is automatically detached, so that the needle body is more convenient to disassemble.

[0020] Fig. 2 It is an upper sleeve body structure diagram of the utility model.
[0021] LEGEND:
[0022] 1, needle body; 2, upper sleeve body; 3, lower sleeve body; 4, pressing sheet. DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0024] EMBODIMENT:
[0025] Please refer to Figs. 1-2 The utility model provides an ignition needle adjusting device, including needle body 1, the outer surface of needle body 1 is formed with convex point by protruding, needle body 1 is installed with upper sleeve body 2 and lower sleeve body 3, upper sleeve body 2 and lower sleeve body 3 structure are same, upper sleeve body 2 includes ring body and pressing sheet 4, and ring body inside is provided with pressing sheet 4 around axis.
[0026] Specifically, the convex points are arranged on the ceramic sleeve or the metal sleeve of the needle body 1, and are easily integrally formed.
[0027] Specifically, the distance between the convex points is 4mm-5mm, and the number of convex points is reduced.
[0028] Specifically, the pressing sheet 4 is an elastic metal sheet, the pressing sheet 4 is arranged in a clockwise or counterclockwise oblique manner, the number of the pressing sheet 4 is three to six, and the pressing sheet 4 is easily displaced up and down by rotating the upper sleeve body 2 and the lower sleeve body 3.
[0029] Working principle:
[0030] In use, compared with the previous ignition needle installation height, the height of the upper sleeve body 2 is rotated on the needle body 1, because the inner side of the upper sleeve body 2 is provided with a pressing plate 4, so that the upper sleeve body 2 forms a extrusion fixing force on the needle body 1, and will not loosen and slide down, and the position will be more stable, and then the lower sleeve body 3 is installed below the stove, the upper sleeve body 2 and the lower sleeve body 3 fix the needle body 1 in the installation hole position, when disassembling, the needle body 1 is directly pulled up, the lower sleeve body 3 will fall off due to the obstruction of the stove plate, and can be taken out.
[0031] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
