Description
Technical Field
The utility model relates to a switch field, especially a take self-locking function's handle push switch.
Background
A switch is a device that causes an electrical circuit, gas circuit, or other pathway to open and close during use of the device. Most often when operating an electromechanical device, in which one or several contacts are closed, indicating a conducting state; when the contact is opened, the contact is not conducted, and an open circuit state is formed.
Most switches on the market belong to touch switches at present, namely a switch key needs to be pressed when the switch is used, the switch belongs to a switch-on state at the moment, and when a hand is released, the switch returns immediately, and the switch is switched off and is in a switch-off state.
The self-locking switch generally has a mechanical locking function, and is pressed down, the button cannot jump up completely after the hand is released, the self-locking switch is in a locking state, and the self-locking switch needs to be pressed once again to unlock and jump up completely. It is called a self-locking switch. Early television sets and displays that were directly powered off completely were the type of switch used. The common self-locking button switch is a common button switch. When the switch button is pressed for the first time, the switch is switched on and kept, namely, self-locking is realized, and when the switch button is pressed for the second time, the switch is switched off, and meanwhile, the switch button is popped out.
The self-locking means that the switch can be kept in a certain state (on or off) through a locking mechanism, and the switch is in a knob type, a plate type (including a knob switch and a boat-shaped switch) and a button type in terms of operation modes; most of the switches can be kept (locked) in a connection or disconnection state after operation, such as a lamp switch and a fan speed regulation switch which are used daily, and the switches do not need to emphasize whether the switches are self-locked or not because the switches have obvious operation directions; only the push-button switch is pressed when in use, most push-button switches are used for connecting or disconnecting the circuit when pressed, and the state is recovered after release. The button switch is provided with a self-locking device in order to keep a pressed state, and the button switch is also kept in a switch-on or switch-off state by self-locking performance like a common switch, namely the switch with self-locking. The self-locking switch is widely used in work, and an operator can directly keep the switch at the maximum stroke position and keep a closed conduction state without pressing the switch for a long time after switching on the switch.
The structure of the current area locking function switch on the market at present does: on the original switch, a locking pin is arranged on the switch side of the original switch, a hole is formed in the switch, the locking pin can axially reciprocate, and the axis of the locking pin and the axis of the hole in the switch are located at the same position. The locking pin can be inserted into a hole in the switch mountain during axial movement. After the switch is pressed down, the switch is in the on position, the locking pin is pressed down at the moment, and the locking pin moves along the axial direction and enters a hole in the switch. After the switch is loosened, the switch returns to the off state under the action of the return spring, at the moment, the locking pin is combined with the hole, the switch is prevented from returning to the off state under the action of the return spring, the switch is still in the combined position, and therefore the switch is locked and is kept in the combined state.
When the switch is to be released, the locking pin is moved in the axial direction in the opposite direction, and the locking pin is separated from the hole of the switch. When the locking pin is completely separated, the switch is released, and returns to the initial state under the action of the return spring and is in the disconnected position, so that the tool or equipment stops working. This operation affects the convenience of operation because an additional auxiliary lock button is required to implement the lock function or the unlock function.
The locking of such switches currently used is capable of performing the function of locking the switch in the on position for a long time in operation. However, when the operation is completed by two hands of an operator, the switch is in an open position by pressing the switch with one hand, and the locking pin is moved by the other hand to move axially to be combined with the inner hole of the switch. When the locking state is quitted, the operation also needs two hands, one hand presses the switch, the other hand operates the locking pin to enable the locking pin to move in the reverse axial direction, and after the locking pin is separated from the hole of the switch, the switch is released to enable the switch to return. Such a mode has certain requirements on the operation of tools or equipment, and particularly when complex equipment is operated, an operator often cannot hold the other hand to lock or unlock the locking operation, so that the locking switch cannot be effectively used.
In the processing process, the locking pin is matched with the hole in the switch and inserted into the hole, so that certain requirements on processing precision and position precision are required, and higher processing and manufacturing cost is achieved. In the use process, the abrasion of the hole, the abrasion of the locking pin and the abrasion of a switch moving part can influence the relative positions of the locking pin and the hole on the switch, so that the locking difficulty or the locking releasing difficulty can be caused. Therefore, the currently used locking switches cannot meet the production requirements.
The above-mentioned defects become the problems to be further solved by the present invention.
