Description

Technical Field

[0001] The utility model relates to the technical field of handles, in particular to a push-button switch handle. Background Art

[0002] In various electrical equipment and mechanical devices, the switch handle is a key component for starting, stopping and switching the state of the equipment. Traditional push-button switch handles have exposed many defects in practical applications. On the one hand, there is a lack of an effective locking mechanism. In some scenarios with extremely high requirements for operation safety, such as industrial automation production lines and high-voltage power equipment, it is very easy for the switch state to change due to accidental touch or collision by personnel, resulting in equipment failures, production accidents, and even endangering the lives of operators. On the other hand, although the existing switch handles can meet the basic opening and closing requirements in terms of function, they cannot meet the differentiated requirements in special working environments. For example, in some places where strict control of the equipment operation state is required, such as data centers and chemical workshops, when the equipment is running normally, it is impossible to effectively prevent unauthorized personnel from casually shutting down the equipment; and when the equipment is under maintenance and repair, it is also difficult to ensure that the switch is in a locked and power-off state.

[0003] Patent CN221239523U discloses a closing and opening handle. Specifically, when the rotating handle is rotated to the closing or opening position, the locking member is pressed to slide in the chute. When the end portion is inserted into the locking groove, the handle is locked and cannot be rotated, and a lock is hung in the padlock hole. This structure solves the problem that the handle cannot stably maintain the closing or opening state. However, in the actual use process of this technical solution, the operation method is as follows: a user holds the handle with one hand, and then uses the thumb of the same hand or the other hand to push the locking member forward to lock the handle. First, this structure has the problem of unsmooth sliding of the locking member. The locking member is slidably arranged in the chute, and the extended end portion of the locking member is slidably arranged in the first guiding groove. It is necessary to drive the end portion to drive the entire locking member to slide. The end portion of the locking member is relatively small. During operation, the locking member is jointly affected by the downward pressure and the forward thrust. When pushing the end portion, it is easy to cause the locking member to tilt and then get stuck with the chute, resulting in poor operation feel. Secondly, this operation method does not conform to ergonomics, and the unlocking operation is relatively laborious. In addition, since its first guiding groove is open, it is easy for dust and the like to enter, which is likely to hinder the movement of the locking member and affect its service life. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects and deficiencies existing in the prior art, and provide a push-button switch handle. The utility model drives the locking member to lock the handle by pressing the driving button. The driving button only receives the downward pressure, and the driving button slides smoothly along the direction of the pressure. The pressing operation method conforms to ergonomics, the unlocking operation is more labor-saving, is convenient for single-handed operation, and also prevents dust from entering the handle.

[0005] The technical solution adopted by the utility model is as follows: A push-button switch handle includes a mounting base and a handle. The handle is inserted into the mounting base and forms a rotatable connection with the mounting base. It also includes a locking member for locking the handle when it is in the closing or opening state. A handle extends from one side of the handle, and a driving button linked to the locking member is slidably arranged on the handle. The sliding direction of the driving button is the same as the extending direction of the handle. The driving button has a first position where the end extends out of the handle and a second position where the end extends into the handle. When the driving button is in the first position, the locking member unlocks the handle. When the driving button is in the second position, the locking member locks the handle.

[0006] At least two locking holes corresponding to the closing or opening positions of the handle are formed on the mounting base. The locking member is slidably arranged on the handle. A padlock hole is formed on the handle, and a positioning hole is formed on the driving button. When the driving button is in the first position, the positioning hole and the padlock hole are staggered and blocked, and the driving button drives the locking member to extend out of the locking hole. When the driving button is in the second position, the positioning hole and the padlock hole are coaxially communicated, and the driving button drives the locking member to extend into the locking hole.

[0007] One end of the locking member is provided with a first inclined surface, and one side of the driving button is provided with a second inclined surface that slidably cooperates with the first inclined surface. The driving button drives the locking member to extend into or out of the locking hole through the sliding cooperation of the second inclined surface and the first inclined surface. The slope of the first inclined surface is 1° - 3° less than the slope of the second inclined surface.

[0008] A through hole for the locking member to slide is formed on the handle, and a groove for the driving button to slide is formed on the handle. The through hole and the groove are communicated and the axes are perpendicular to each other. The locking member passes through the through hole and is linked to the driving button located in the groove.

[0009] A fixing plate is provided at one end of the handle close to the mounting base. A guiding hole corresponding to the through hole and a screw hole for fixedly connecting with the handle are formed on the fixing plate. The locking member includes a positioning wedge block and an inserting section for extending into the locking hole that are connected in sequence. The first inclined surface is arranged on the positioning wedge block. A first spring is sleeved on the inserting section. One end of the first spring abuts against the positioning wedge block and the other end abuts against the fixing plate. When the driving button is in the second position, the locking member passes through the guiding hole and then extends into the locking hole.

[0010] A second spring is further arranged in the groove. One end of the second spring abuts against the bottom wall of the groove and the other end abuts against the driving button.

[0011] One slider protrudes from each of the two side walls of the driving button, and one guide groove adapted to the slider is recessed from each of the two inner walls of the groove.

[0012] One side surface of the handle close to the mounting base is provided with anti-slip ridges.

[0013] A limiting member is slidably arranged on the handle. At least two limiting holes corresponding to the closing or opening positions of the handle are formed on the mounting base. A third spring is sleeved outside the limiting member. The limiting member is pressed towards the mounting base by the third spring. When the driving button is in the second position, the limiting member slides into the limiting hole.

[0014] The beneficial effects of the present utility model are as follows: By pressing the driving button, the locking member locks the handle. The driving button only receives a downward pressure and smoothly slides along the direction of the pressure. The pressing operation mode conforms to ergonomics, the unlocking operation is more labor-saving, is convenient for single-handed operation, and also prevents dust from entering the handle.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0025] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0026] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, an embodiment of the utility model is a push-type switch handle, comprising a mounting base 1 and a handle 2, wherein the handle 2 is inserted into the mounting base 1 and rotatably connected with the mounting base 1, and further comprising a locking member 4 for locking the handle 2 when the handle 2 is in a closed or open state, a handle 21 extending from one side of the handle 2, a driving button 5 linked to the locking member 4 being slidably provided on the handle 21, the sliding direction of the driving button 5 being the same as the extending direction of the handle 21, the driving button 5 having a first position in which the end extends out of the handle 21 and a second position in which the end extends into the handle 21, when the driving button 5 is in the first position, the locking member 4 unlocks the handle 2, and when the driving button 5 is in the second position, the locking member 4 locks the handle 2.

[0028] The beneficial effects of such a setting are as follows. In the present utility model, the locking member is locked by pressing the driving button, and the driving button only receives a downward pressure. The driving button slides smoothly along the direction of the pressure. The driving button can be arranged on the front surface of the handle or at the end of the handle. In this embodiment, the driving button is arranged at the end of the handle. When operating with one hand, the driving button can be easily pressed with the thumb to lock the handle. The pressing operation mode conforms to ergonomics, the unlocking operation is more labor-saving, it is convenient for one-handed operation, and the operation feel is better. The slot for the driving button to slide will not be open and exposed to the outside, preventing dust from entering the handle.

[0029] Further setting: At least two locking holes 3 corresponding to the closing or opening positions of the handle 2 are formed on the mounting seat 1. The locking member 4 is slidably arranged on the handle 2. A padlock hole 6 is formed on the handle 21. A positioning hole 7 is formed on the driving button 5. When the driving button 5 is in the first position, the positioning hole 7 and the padlock hole 6 are staggered and blocked, and the driving button 5 drives the locking member 4 to extend out of the locking hole 3. When the driving button 5 is in the second position, the positioning hole 7 and the padlock hole 6 are coaxially communicated, and the driving button 5 drives the locking member 4 to extend into the locking hole 3. The beneficial effects of such a setting are as follows. Through the linkage cooperation of the driving button and the locking member, the handle can be locked when in the closing or opening position, that is, the handle cannot rotate relative to the mounting seat. The specific operation is to press the driving button to extend into the handle, and the driving button can make the linked locking member extend into the locking hole of the mounting seat. Then, by passing a padlock through the positioning hole and the padlock hole at the same time, the driving button is kept in the second position of extending into the handle, thereby causing the locking member to remain in the position of extending into the locking hole. This locking structure has the advantages of simple and convenient operation, effectively preventing the change of the switch state caused by accidental touch of the handle. In this embodiment, three positioning holes and three padlock holes are respectively provided, which is convenient for hanging multiple padlocks on the handle or arbitrarily selecting a pair of holes to install a padlock, further improving the locking ability.

[0030] Further setting: One end of the locking member 4 is provided with a first inclined surface 8, and one side of the driving button 5 is provided with a second inclined surface 9 that slidably cooperates with the first inclined surface 8. The driving button 5 drives the locking member 4 to extend into or out of the locking hole 3 through the sliding cooperation of the second inclined surface 9 and the first inclined surface 8. The slope of the first inclined surface 8 is 1°-3° less than the slope of the second inclined surface 9.

[0031] The beneficial effects of such a setting are as follows. A relative sliding cooperation is formed between the locking member and the driving button through the first inclined surface and the second inclined surface. The slope of the first inclined surface is less than that of the second inclined surface, generating a certain gap, improving the smoothness of the relative sliding and preventing jamming.

[0032] Further setting: A through hole 10 for the sliding setting of the locking member 4 is provided on the handle 2, and a groove 11 for the sliding setting of the driving button 5 is provided on the handle 21. The through hole 10 communicates with the groove 11 and their axes are perpendicular to each other. The locking member 4 passes through the through hole 10 and is linked with the driving button 5 located in the groove 11.

[0033] The beneficial effects of such a setting are as follows. Since the through hole and the groove are perpendicular to each other, the installed locking member and the driving button are also perpendicular, ensuring the effective transmission of force. When the driving button slides, it can effectively drive the locking member to slide.

[0034] Further setting: One end of the handle 2 close to the mounting base 1 is provided with a fixing plate 12. A guiding hole 13 corresponding to the through hole 10 and a screw hole 14 for fixedly connecting with the handle 2 are provided on the fixing plate 12. The locking member 4 includes a positioning wedge 15 and an insertion section 16 for extending into the locking hole 3 which are connected in sequence. The first inclined surface 8 is arranged on the positioning wedge 15. A first spring 17 is sleeved on the insertion section 16. One end of the first spring 17 abuts against the positioning wedge 15 and the other end abuts against the fixing plate 12. When the driving button 5 is in the second position, the locking member 4 passes through the guiding hole 13 and then extends into the locking hole 3.

[0035] The beneficial effects of such a setting are as follows. The guiding hole of the fixing plate is used to guide the locking member, so that the locking member can be accurately aligned and extended into the locking hole. Moreover, the locking member has a reset function by installing the first spring. When the reset block slides to the first position, the first spring drives the locking member to extend out of the locking hole. The fixing plate also has the function of abutting and limiting the first spring.

[0036] Further setting: A second spring 18 is also provided in the groove 11. One end of the second spring 18 abuts against the bottom wall of the groove 11 and the other end abuts against the driving button 5.

[0037] The beneficial effects of such a setting are as follows. The driving button has a reset function through the second spring. When the padlock is not installed and the driving button is not pressed, the driving button remains in the first position, that is, the handle can rotate.

[0038] Further setting: A slider 19 protrudes from each of the two side walls of the driving button 5, and a guide groove 20 adapted to the slider 19 is recessed in each of the two inner walls of the groove 11.

[0039] The beneficial effects of such a setting are as follows. Through the cooperation of the slider and the guide groove, the sliding direction of the driving button is guided, the sliding is smoother, and it also prevents the driving button from rotating circumferentially, thereby causing the padlock hole and the positioning hole to be misaligned.

[0040] Further setting: The surface of the handle 21 close to the mounting base 1 is provided with anti-slip ridges 22.

[0041] The beneficial effects of such a setting are as follows. The anti-slip convex stripes enhance the friction and increase the rotational feel of the handle.

[0042] Furthermore, a limiting member 23 is slidably arranged on the handle 2. At least two limiting holes 24 corresponding to the closing or opening positions of the handle 2 are formed on the mounting base 1. A third spring is sleeved outside the limiting member 23. The limiting member 23 is pressed towards the mounting base 1 through the third spring. When the driving button 5 is in the second position, the limiting member 23 slides into the limiting hole 24.

[0043] The beneficial effects of such a setting are as follows. Through the cooperation of the limiting member and the limiting hole, the handle is limited when it rotates to the closing or opening position. It is necessary to apply more force to rotate the handle so that the handle can rotate. The handle will not be easily rotated, which improves the feel and also enhances the safety.

[0044] Generally speaking, through the simple pressing action of the driving button, the switching between the locked state and the active state of the handle can be realized, and vice versa. The operation method is intuitive and simple, without complex operation procedures, which can improve the operation efficiency of users. The handle has an active state and a locked state, which can meet the usage requirements in different scenarios. When the handle needs to be operated and adjusted, it is switched to the active state; when the position of the operating member is determined, it is switched to the locked state to prevent it from rotating accidentally and ensure the stable operation of the device.

[0045] The mounting base is fixedly arranged, and the handle forms a rotatable mechanical connection with the mounting base. This structural design ensures the stability of the operating member during rotation. At the same time, the connection mode between the locking member and the driving button further enhances the reliability of the overall structure and reduces the probability of failure.

[0046] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
