Description

Technical Field

[0001] This application relates to the technical field of grease guns, and in particular to a grease gun linkage switch. Background Technology

[0002] Grease guns, widely used in mechanical lubrication, function by precisely injecting grease into the friction surfaces of mechanical parts through pressure. Most grease guns employ a manual trigger mechanism, typically involving a push-button action that momentarily opens a one-way valve, achieving a "press-dispense-release-close" intermittent grease injection mode.

[0003] Operators need to repeatedly press the button to complete a long-stroke grease injection operation. Taking a certain model of grease gun as an example, a single press only dispenses 0.5ml of grease, and it takes 15-20 consecutive presses to fill a standard bearing. The high frequency of operation reduces work efficiency by about 40% and is prone to causing muscle strain in the operator's hands.

[0004] Therefore, there is an urgent need to develop a new type of drive control mechanism that, while retaining the lightweight characteristics of manual operation, enables controllable switching of the grease gun's injection mode. Through mechanical structural innovation, operators can freely choose between inching or continuous injection modes according to working conditions, fundamentally improving the ergonomics and operational safety of the grease gun.

[0024] The following will be described in detail in combination with the drawings Figures 1-4 The present application will be further described in detail.

[0025] The embodiment of the present application discloses a butter gun linkage switch. Referring to Figures 1-2The butter gun linkage switch comprises a gun body 1, an electric control switch 2 for controlling the start and stop of the motor is arranged on the gun body 1, that is, the oil pump in the butter gun is started by pressing the electric control switch 2, so that the effect of pumping oil is realized. A switch button 3 for pressing the electric control switch 2 is rotationally connected to the gun body 1, and a control mechanism 4 for controlling the state of the switch button 3 is arranged on the gun body 1; that is, the electric control switch 2 is pressed by pressing the switch button 3, so that the effect of starting is realized, and the position of the switch button 3 can be fixed by the control mechanism 4, so that the switch button 3 cannot be pressed and is in a normally closed shutdown protection state, or the switch button 3 can be fixed in the pressed control switch state to realize the effect of long-time starting work.

[0026] In combination Figures 3-4 The control mechanism 4 comprises an unlocking button 41 slidably arranged on the gun body 1, a lock ring is arranged on the switch button 3, a baffle 42 for preventing the switch button 3 from being pressed and started is arranged on the unlocking button 41 in the sliding direction, and a retaining hook 43 for retaining the button switch to press and start the electric control switch 2 is arranged on the unlocking button 41, the retaining hook 43 and the baffle 42 are arranged in a spaced manner to form an avoiding groove 44 for the normal rotation of the switch button 3. That is, when personnel do not need to use it, the switch button 3 is prevented from being accidentally touched by personnel to cause the equipment to start, the unlocking button 41 can be pressed to move the baffle 42 to the corresponding side of the switch button 3 along with the unlocking button 41, so that the switch button 3 is blocked by the baffle 42 and cannot be rotated, thereby preventing the effect of accidental starting of the control switch. When normal operation of the butter gun is needed, the unlocking button 41 can be operated to make the avoiding groove 44 correspond to the switch button 3, so that the switch button 3 can be normally pressed to start the butter gun and realize the effect of oil injection. When long-time starting of the butter gun is needed to realize long-time oil injection, the switch button 3 can be pressed to press the control switch and start the butter gun, and then the unlocking button 41 is pressed by the thumb to move the hook 43 to hook on the lock ring, so that the lock ring is blocked by the hook 43, thereby preventing the switch button 3 from returning, and the effect of long-time stable oil supply is realized.

[0027] In order to prevent the lock ring from being separated from the hook 43 and ensure normal work, the hook 43 is arranged in an L shape, so that when the lock ring is hung in the hook 43, the bending protrusion of the hook 43 in the upward opening direction can prevent the lock ring from being separated, thereby ensuring the reliability of the lock.

[0028] In order to facilitate personnel reset, the gun body 1 is provided with a reset member for resetting the unlocking button 41, the reset member comprises a sliding groove 45 arranged on the gun body 1, the unlocking button 41 is provided with a sliding handle 46 arranged in the sliding groove 45, a spring is arranged in the sliding groove 45, and the both ends of the spring are respectively abutted with the sliding handle 46 and the gun body 1, so that when the personnel unlocks, only the switch button 3 needs to be pressed, the locking ring is separated from the bending and protruding part of the hook 43, and then is not blocked, at this time, the unlocking button 41 is transversely moved under the action of the reset spring 47, so that the hook 43 is separated from the locking ring, and then the automatic unlocking effect is realized, thereby facilitating personnel operation.

[0029] In order to ensure the accuracy of the position of the unlocking button 41, the gun body 1 is provided with a metal spring 5, the metal spring 5 is provided with a positioning protrusion, the unlocking button 41 is provided with a pair of clamping protrusions 411 for clamping the positioning protrusion, and then three positions for clamping the positioning protrusion are formed between the two clamping protrusions 411 and on both sides of the two clamping protrusions 411, thereby forming gears corresponding to the normal starting, anti-misoperation and continuous output of the unlocking button 41. When the unlocking button 41 is pressed, the clamping protrusion 411 and the metal spring 5 form a jerk feeling, thereby ensuring whether the unlocking button 41 is pressed in place, and ensuring the normality of the function.

[0030] The implementation principle of the grease gun linkage switch in the embodiment of the application is that: by pressing the switch button 3, the electric control switch 2 is extruded, the starting effect is realized, the position of the switch button 3 can be fixed by the control mechanism 4, so that the switch button 3 cannot be pressed and is in the normal closed shutdown protection state, the switch button 3 can be fixed in the pressed control switch state, the long-time starting work effect is realized; when the personnel does not need to use, the personnel misoperation of the switch button 3 is prevented, the baffle 42 can be moved to the side corresponding to the switch button 3 by pressing the unlocking button 41, so that the switch button 3 is blocked by the baffle 42 and cannot be rotated, thereby preventing the misoperation of the control switch, thereby facilitating the personnel to use.

[0031] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape and principle of the application should be covered in the protection scope of the application.
