Description

Technical Field

[0001] The utility model belongs to the field of spring needle equipment, in particular to a spring-type contact spring needle. Background Art

[0002] The spring-type contact spring pin is an electronic connection element that realizes the contact conduction function by providing elastic force with a spring. In actual use, the current spring-type contact spring pin has the problem that most of the spring-type contact spring pins are single-stroke, although the single-stroke design is relatively simple and the manufacturing and maintenance costs are low. It does not require a complex structure to achieve multi-stroke switching, which reduces the production difficulty and cost investment, and also reduces the links where failures may occur, improving the overall stability. However, the single stroke means the singleness of function, which cannot meet the flexible switching requirements for different contact forces and strokes in some complex application scenarios. This is because there is a lack of multi-stroke components. The lack of multi-stroke components will not only lead to the above problems, but also limit its application in some equipment that requires precise control and multi-mode operation, and cannot give full play to its potential. Secondly, the single stroke will lead to the problem of insufficient adaptability in certain specific situations, so it is necessary to propose a new structure to solve the above technical problems.

[0021] 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 of 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.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a spring-type contact spring needle, comprising: a spring needle body 100, a syringe 200 and a syringe 300, the inner movable card of the syringe 200 is equipped with the spring needle body 100, the inner wall of the syringe 200 is equipped with a spring 220, the inner wall of the syringe 200 is equipped with an oil layer 240, the lower end of the syringe 200 is equipped with a contact base 230, and the inner wall of the syringe 300 is equipped with a syringe through the contact base 230. One 200, an oil layer 2 320 is installed on the inner wall of the syringe 2 300, a spring 2 310 is installed inside the syringe 2 300, a lubrication assembly 210 is installed on the upper surface of the syringe 200, the lubrication assembly 210 includes: a mounting plate 211, a lubrication layer 212, a fixing rod 213 and a spring 3 214, the lubrication layer 212 is installed on the inner surface of the mounting plate 211 through the fixing rod 213, and the spring 3 214 is installed on the outer surface of the fixing rod 213.

[0023] See also Figures 1 to 4 As the first embodiment of the utility model: the diameter of the elastic needle body 100 is smaller than the diameter of the syringe 200, the upper end of the elastic needle body 100 is an arc structure, the lower end of the elastic needle body 100 is clamped inside the syringe 200, the upper end of the syringe 200 is an open design, and a spring 220 is fixed at the bottom center of the syringe 200;

[0024] The outer surface of the spring 220 abuts against the oil layer 240 on the inner wall of the syringe 200, and the end of the spring 220 away from the syringe 200 is connected to the lower center of the elastic needle body 100. The length of the syringe 200 is the same as that of the elastic needle body 100, and two mounting plates 211 are symmetrically installed on the upper surface of the syringe 200;

[0025] The mounting plate 211 is an arc-shaped structure, and the arc-shaped structure of the mounting plate 211 matches the elastic pin body 100;

[0026] A lubricating layer 212 is installed on the inner surface of the mounting plate 211, and a surface of the lubricating layer 212 away from the mounting plate 211 abuts against the outer surface of the spring pin body 100. A fixing rod 213 is installed through the outer surface of the mounting plate 211, and a spring 214 is sleeved on the outer surface of the fixing rod 213.

[0027] When in use, first install the entire device at the required installation position. After the installation is completed, when the elastic needle body 100 is needed, it is first contacted with the upper end of the elastic needle body 100. After contacting the upper end of the elastic needle body 100, the device in contact with the elastic needle body 100 will press the elastic needle body 100 downward. At this time, the downward moving elastic needle body 100 will compress the spring 1 220 inside the syringe 200. After the spring 1 220 is fully compressed, it reaches the first stroke. After reaching the first stroke, the user can use the first stroke according to his or her needs. If the second stroke is needed, the user can continue to move the elastic needle body 100 downward, so that the elastic needle body 100 drives the contact base 230 to move inside the syringe 2 300, so that the contact base 230 compresses the syringe. The spring 2 310 inside the second 300, when the spring 2 310 is fully compressed, the second stroke will also be connected and the user can use it. When the spring 1 220 is compressed, the elastic force of the spring 1 220 is greater than the elastic force of the spring 2 310, so that the spring 2 310 will not be compressed due to the compression of the spring 1 220. The spring 1 220 and the spring 2 310 form two strokes (the spring 1 220 is the first stroke, and the spring 2 310 is the second stroke). At this time, the two strokes can provide different degrees of contact pressure and position control, adapt to a wider range of application scenarios and needs, make the operation more precise, and can flexibly choose to use the first stroke or the second stroke (total stroke) according to different working conditions or requirements, thereby improving the adaptability of the spring needle body 100 in various situations.

[0028] See also Figures 1 to 4 As the second embodiment of the utility model: the diameter of the second syringe 300 is greater than the diameter of the first syringe 200, the length of the second syringe 300 matches the length of the first syringe 200, a second spring 310 is installed at the center of the inner bottom of the second syringe 300, and the outer surface of the second spring 310 abuts against the second oil layer 320;

[0029] One end of the second spring 310 away from the second syringe 300 is connected to the lower surface of the contact base 230, the length of the second spring 310 is smaller than the diameter of the first spring 220, the diameter of the second spring 310 is larger than the diameter of the first spring 220, and the elastic force of the second spring 310 is twice that of the first spring 220;

[0030] During use, when the elastic needle body 100 is compressed downward, the outer surface of the elastic needle body 100 will be lubricated because the spring three 214 abuts the lubricating layer 212. When the second stroke is running and the first stroke is running, the spring one 220, the spring two 310 and the syringe one 200 will have the oil layer one 240 and the oil layer two 320 abutting respectively, so as to lubricate the spring one 220, the spring two 310 and the syringe one 200. After using for a period of time, the user can drip lubricating oil into the syringe one 200 and the syringe two 300 so that the oil layer one 240 and the oil layer two 320 can continue to be used. Since the lubricating layer 212 can effectively lubricate the inside of the syringe one 200 when the elastic needle body 100 moves up and down, the friction between the elastic needle body 100 and the syringe one 200 and between the syringe one 200 and the syringe two 300 can be reduced, the wear caused by friction is reduced, and the service life of the entire elastic needle device is extended.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
