Description

Technical Field

[0001] The utility model relates to the technical field of socket magnets, and particularly relates to a self-locking knob plunger. Background Art

[0002] Traditional socket magnets are assembled from neodymium iron boron strong magnets, metal shells, copper rings, etc. The metal shells are processed by numerical control lathes, and most of the materials are made of stainless steel and carbon steel. This structure is simple and the cost is low. The advantages of socket magnets are that they are easy to install and use, and provide a certain degree of protection for the magnets. However, in some cases, due to the existence of the base, the design and use of the magnets may be restricted to a certain extent. Especially in applications that require high flexibility, if a strong impact is applied or the adsorption surfaces are pressed tightly against each other, the magnet cover may fall off. In addition, if the magnet surface directly bears a strong impact, the magnet may be damaged. Therefore, when using socket magnets, these potential risks need to be considered and corresponding preventive measures need to be taken. Once the metal shell of the socket magnet falls off during the process, it means that the entire magnet component needs to be repurchased, which is both time-consuming and costly.

[0003] In view of the above-mentioned potential safety hazards, a self-locking knob plunger is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a self-locking knob plunger to solve the problems in the prior art.

[0007] The locking mechanism is arranged between the fixing screw and the knob;

[0008] The return spring is installed in the fixing screw and sleeved on the front end pin.

[0009] Preferably, an anti-slip layer is arranged on the outer part of the knob.

[0010] Preferably, after the knob is pulled outwards and rotated 90°, it abuts against the outside of the locking mechanism to lock.

[0011] Preferably, the locking mechanism is a bracket.

[0012] Preferably, a space is left in the middle of the bracket to pass through the front end pin; the outer diameter of the bracket is the same as the middle diameter of the knob.

[0013] Preferably, in one solution, one end of the return spring is fixed to the fixing screw, and the other end is fixedly sleeved on the outer wall of the front end pin.

[0014] Due to the application of the above technical solution, the beneficial effects of the present application compared with the prior art are as follows:

[0015] A self-locking knob plunger of the present application, through the settings of the knob, the locking mechanism, the return spring, the fixing screw and the front end pin, enables the knob plunger to have a locking mechanism. When the knob is pulled out, the front end pin retracts. If it is rotated 90° while keeping the pulled-out state, the retracted state of the front end pin can be locked. This locking mechanism allows the user to fix the knob at a specific position according to needs. Whether it is for adjusting the device or for protecting the device from accidental operations, this locking function is very useful; at the same time, such a design takes into account the user's usage habits and operation convenience, providing a convenient operation method.

[0026] Embodiment 1

[0027] Appendix Figure 1 、 2 A self-locking knob 1 plunger according to the present utility model, comprising a knob 1, a locking mechanism 2, a return spring 3, a fixing screw 4 and a front-end pin 5;

[0028] The knob 1 is arranged at one end of the fixing screw 4 and connected to the front end pin 5; after the knob 1 is pulled outwards and rotated by 90°, it abuts against the outside of the locking mechanism 2 to lock;

[0029] The locking mechanism 2 is arranged between the fixing screw 4 and the knob 1; the locking mechanism 2 is a bracket; a hollow is left in the middle of the bracket to pass through the front end pin 5; the outer diameter of the bracket is the same as the middle diameter of the knob 1.

[0030] The return spring 3 is installed in the fixing screw 4 and sleeved on the front end pin 5; one end of the return spring 3 is fixed on the fixing screw 4, and the other end is fixedly sleeved on the outer wall of the front end pin 5

[0031] In order to facilitate the grasping of the knob 1 during use, an anti-slip layer is provided on the outside of the knob 1, which increases the friction between the human hand and the knob 1 and is more convenient for personnel to use.

[0032] During use, when the knob 1 is pulled out, the front end pin 5 retracts. If the knob 1 is rotated by 90° while keeping the pulled-out state, and the knob 1 is stuck on the locking mechanism 2, that is, the bracket, the retracted state of the front end pin 5 can be locked; when unlocking, just rotate the knob 1 by 90° while keeping the pulled-out state, and then release the knob 1, and the front end pin 5 will return to the protruding state under the action of the return spring 3.

[0033] A self-locking knob 1 plunger of the present application, through the settings of the knob 1, the locking mechanism 2, the return spring 3, the fixing screw 4 and the front end pin 5, enables the knob 1 plunger to have a locking mechanism. When the knob 1 is pulled out, the front end pin 5 retracts. If it is rotated by 90° while keeping the pulled-out state, the retracted state of the front end pin 5 can be locked. This locking mechanism enables the user to fix the knob 1 at a specific position according to needs. Whether it is for adjusting the device or for protecting the device from accidental operations, this locking function is very useful; at the same time, such a design takes into account the user's usage habits and operation convenience and provides a convenient operation method.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
