Description

Technical Field

[0001] The present application relates to the technical field of switches, and in particular to a switch structure integrating self-locking and anti-self-locking. Background Art

[0002] As a common component with on-off functions, switches are widely used in the field of electronic devices. However, in certain specific application scenarios, such as industrial control, precision instrument operation or safety control systems, the control requirements for switches are more stringent. This requires the switch to be able to maintain a stable working state after operation, while also ensuring that it can be quickly unlocked under certain circumstances to facilitate emergency operation or adjustment, that is, it has both self-locking and anti-self-locking functions.

[0003] However, most switch products on the market currently only have a single function, or although they provide self-locking and anti-self-locking integrated switches, they require complex operating steps or additional components to implement, which not only increases the complexity of operation, but also affects the overall compactness and reliability of the equipment, and increases production costs.

[0004] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention

[0005] Based on this, the present application provides a switch structure integrating self-locking and anti-self-locking to solve one of the above technical problems.

[0006] The technical solution adopted by the present application to solve the technical problem is: a self-locking and anti-self-locking integrated switch structure, comprising: a housing, in which a limit rib and a locking reinforcement rib are formed, and the middle section of the housing is a handle; a trigger, one end of which is rotatably connected to the housing, and the middle section is connected to the housing through a return spring; a dial button, which is rotatably arranged on the trigger and connected to the trigger through a dial button spring, a hook is provided at one end of the dial button, and a first protrusion and a second protrusion are provided on the dial button;

[0007] The following statuses are available:

[0008] In the anti-self-locking state, the hook contacts the limiting rib, and the trigger contacts the dial button, so that the trigger cannot be pressed down, thus realizing the anti-self-locking function;

[0009] In the self-locking state, the dial button is pushed to disengage it from the limiting rib, and the trigger can be pressed down to increase the forward push stroke of the dial button, so that the hook is hung on the locking reinforcement rib, and the trigger is stuck at the second protrusion, thereby achieving the purpose of locking the switch.

[0010] In some embodiments, the trigger has a positioning column at the tail end, which cooperates with a cylindrical groove opened inside the shell to allow the trigger and the shell to rotate, and a control block is provided on the trigger.

[0011] In some embodiments, a switch is provided inside the housing, and the switch is connected to the control block for controlling the on and off of the switch.

[0012] In some embodiments, the dial button is fixed to the trigger by a cylindrical pin, and the hook is limited to move between the limiting rib and the locking reinforcement rib.

[0013] In some embodiments, it is characterized in that the first protrusion and the button are at a right angle and match the shape of the limiting rib, and the second protrusion matches the shape of the contact point of the trigger.

[0014] In some embodiments, in the self-locking state, the first protrusion cooperates with the limiting rib to achieve a limiting effect on the dial button.

[0015] In some embodiments, the integral structure is integrated on the handle.

[0016] The beneficial effects of the present application are that the self-locking and anti-self-locking integrated functions of the switch are realized through the cooperation of the trigger, the dial button, the return spring and the reinforcing ribs on the handle. It has a compact structure and is easy to operate. It can improve the control flexibility of the equipment and the user experience while ensuring operational safety, and integrates functions on the handle and trigger to reduce costs.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0024] In the embodiments of this application, please refer to Figure 1-4 As shown, the self-locking and anti-self-locking integrated switch structure mainly comprises: a housing 1, in which a limiting rib 101 and a locking reinforcement rib 102 are formed, and the middle section of the housing 1 is a handle 2; a trigger 3, one end of which is rotatably connected to the housing 1, and the middle section is connected to the housing 1 through a return spring 4; a dial button 5, which is rotatably arranged on the trigger 3 and connected to the trigger 3 through a dial button spring 66, and a hook 501 is provided at one end of the dial button 5, and a first protrusion 502 and a second protrusion 503 are provided on the dial button 5;

[0025] The following statuses are available:

[0026] In the anti-self-locking state, the hook 501 contacts the limiting rib 101, and the trigger 3 abuts against the dial button 5, so that the trigger 3 cannot be pressed down, thus realizing the anti-self-locking function;

[0027] In the self-locking state, the dial button 5 is pushed to disengage it from the limiting rib 101, and the trigger 3 can be pressed down to increase the forward push stroke of the dial button 5, so that the hook 501 is hung on the locking reinforcement rib 102, and the trigger 3 is stuck at the second protrusion 503, thereby achieving the purpose of locking the switch 9.

[0028] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0029] like Figure 2As shown, the trigger 3 has a positioning column 302 at the tail end, which cooperates with the cylindrical groove 8 opened inside the shell 1 to allow the trigger 3 and the shell 1 to rotate, so that the trigger 3 is fixed on the shell 1, wherein a control block 301 is provided on the trigger 3.

[0030] Furthermore, a switch 9 is provided inside the housing 1 , and the switch 9 is connected to the control block 301 for controlling the on and off of the switch 9 .

[0031] like Figure 1 As shown, the button 5 is fixed to the trigger 3 by a cylindrical pin 7 , and the hook 501 is limited to move between the limiting rib 101 and the locking reinforcement rib 102 .

[0032] In some embodiments, it is characterized in that the first protrusion 502 is at a right angle to the button 5 and matches the shape of the limiting rib 101, and the second protrusion 503 matches the shape of the contact point of the trigger 3 to better play a limiting role.

[0033] Specifically, in the self-locking state, the first protrusion 502 cooperates with the limiting rib 101 so that the dial button 5 can only be pushed within a limited range, thereby achieving a limiting effect on the dial button 5 .

[0034] Preferably, the overall structure is integrated on the handle 2, so that the overall structure is more compact, the functions are concentrated, and the cost is reduced.

[0035] like Figure 3-4 As shown, in the original state (anti-self-locking state), the trigger 3 cannot be pressed down on the limiting rib 101, thereby realizing the anti-self-locking function. At this time, due to the limiting effect of the first protrusion 502 and the limiting rib 101, the dial button 5 can only be pushed forward within a limited range; when it is necessary to turn on the machine, the dial button 5 is pushed to disengage it from the limiting rib 101, and the trigger 3 can be pressed down to open the switch 9. Before the trigger 3 is pressed down, the hook 501 cannot be stuck on the reinforcing rib; when it is necessary to lock (self-locking state), the stroke of pushing the dial button 5 forward can be increased so that the hook 501 is hung on the locking reinforcing rib 102, thereby achieving the purpose of locking the switch 9. At this time, due to the limiting effect of the second protrusion 503, the trigger 3 and the dial button 5 play a role of mutual limitation, and the dial button spring 66 and the reset spring 4 are both tightened to keep the switch 9 in the normally open self-locking state. When unlocking is required, the trigger 3 can be pressed, and the trigger 3 can be reset by the toggle spring 66 and the reset spring 4. So far, various embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the embodiments of the present application.
