Description
Technical Field
[0001] This utility model relates to the field of switch technology, specifically a metal push button switch with a locking function. Background Technology
[0002] A push-button switch is a switch that uses a button to actuate a transmission mechanism, causing the moving contact to connect or disconnect with the stationary contact, thus switching the circuit. A traditional push-button switch structure includes a base, a housing mounted on the base, and an operating mechanism located on top of the housing. The base has at least two pins, with a stationary contact at the top of each pin. The operating mechanism has a moving contact that engages with the stationary contact to connect or disconnect. The moving contact includes a bridging rod and moving contacts at both ends of the bridging rod. To achieve normally closed or normally open operation, a self-locking structure is usually incorporated into the switch. A traditional self-locking structure includes a locking cylinder and a locking lever that engages with the locking cylinder. A drawback of this structure is that it increases the length of the switch. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a metal push button switch with a locking function, which is short in length, has a reasonable and stable structure, has a good locking effect, and is reliable when pressed.
[0004] The technical solution adopted by this utility model to solve its technical problem is a metal push button switch with a locking function, including an upper shell, a base, a button, a moving contact, and a pair of stationary contacts. A first sliding cavity is axially extended through the upper shell. The base and the button are positioned opposite each other at opposite ends of the upper shell. The button drives the moving contact to move up and down within the first sliding cavity. The stationary contacts are disposed on the base and cooperate with the two ends of the moving contact. A sliding seat is integrally formed on the lower end surface of the button, and the sliding seat slides and engages with the first sliding cavity. A sliding anti-detachment structure is provided between the two, and the sliding seat is also provided with a through mounting groove. The moving contact is inserted through the mounting groove, and a first spring is provided between the moving contact and the mounting groove. A second sliding cavity is also provided on the left side of the first sliding cavity on the upper shell. A first protrusion is provided on the left side of the sliding seat. The first protrusion slides and engages with the second sliding cavity. A heart-shaped lock cylinder can also be detachably installed on the left side of the first protrusion. A connecting member is also provided in the second sliding cavity. The connecting member is provided with a lock hook. The locking end of the lock hook engages with the heart-shaped lock cylinder.
[0005] The advantages of the above technical solution are as follows: When the button is pressed down, the locking hook slides on the heart-shaped lock cylinder, and the button moves the moving contact downwards. At this time, the locking hook is not locked. When the button is pressed down to the end, the two ends of the moving contact connect the two stationary contacts, and the circuit is completed. When the button is released, the locking hook also locks on the heart-shaped lock cylinder, making the metal button switch self-locking. When the button is pressed again, the locking hook is unlocked from the heart-shaped lock cylinder, the button resets automatically, and the locking hook slides back to its initial position, thus realizing the functions of automatic locking and unlocking by pressing again. Therefore, by using an integrally formed sliding base at the bottom of the button, installation is convenient, and by setting a sliding base... The mounting groove with the first elastic element ensures reliable contact between the moving and stationary contacts. The sliding engagement of the sliding seat and the first sliding cavity, as well as the sliding engagement of the first protrusion and the second sliding cavity, makes the button pressing action more stable and the locking smoother. The detachable heart-shaped lock cylinder is set on the first protrusion, and the split structure makes injection molding more convenient. The lock hook is installed in the second sliding cavity through the connector. The installation and fixing of the lock hook is convenient, and the engagement of the lock hook and the heart-shaped lock cylinder is set on the left side of the sliding seat, thereby reducing the height of the operating mechanism. Therefore, the overall length is short, the structure is reasonable and stable, the locking effect is good, and the pressing is reliable.
[0006] Furthermore, a transverse insertion cavity is provided on the left side of the first protrusion, and the heart-shaped lock cylinder is inserted transversely into the insertion cavity. An insertion positioning structure is also provided between the side wall of the heart-shaped lock cylinder and the side wall of the insertion cavity.
[0007] The advantages of the above technical solution are as follows: After the heart-shaped lock cylinder is inserted horizontally into the cavity, the position of the heart-shaped lock cylinder relative to the lock hook is effectively limited by the insertion positioning structure. Then, the sliding seat is inserted into the first sliding cavity, and the first protrusion is also inserted into the second sliding cavity. After assembly, the problem of the heart-shaped lock cylinder falling off can be effectively prevented. The installation is also reasonable and simple.
[0008] Furthermore, a second protrusion is provided on the right side of the sliding seat, and a third sliding cavity is also provided on the right side of the upper shell connected to the first sliding cavity, with the second protrusion slidingly engaging with the third sliding cavity.
[0009] The advantages of adopting the above technical solution are: the sliding cooperation between the second protrusion and the third sliding cavity makes the button pressing action more stable and the structure is reasonably designed.
[0010] Furthermore, a longitudinal cavity is provided on the right side of the second protrusion. The cavity has a semi-circular structure. A bottom block is provided at the bottom of the third sliding cavity. A pair of first positioning posts are provided between the upper end of the bottom block and the upper end of the cavity. The first positioning posts are used to install the second spring. A third protrusion is also provided on the left side of the bottom block. The third protrusion has a semi-circular structure to slide and cooperate with the cavity.
[0011] The advantages of the above technical solution are as follows: When the button is pressed, the second spring is compressed under the action of the upper end of the bottom block and the upper end of the cavity. During the button reset process, it can provide good elasticity, thereby achieving rapid reset. The setting of the first positioning post makes the installation of the second spring more stable. By setting the cavity into a semi-circular structure, the installation of the second spring is facilitated. At the same time, this structure also reduces the volume of the metal button switch. Furthermore, by setting a sliding cooperation third protrusion and setting the third protrusion into a semi-circular structure, the pressing of the button is more stable.
[0012] Furthermore, the connector is provided with a hollow cavity, a first abutment piece is provided on the upper wall of the hollow cavity, and a second abutment piece is provided on the lower wall of the hollow cavity. The first abutment piece and the second abutment piece elastically abut against the locking hook.
[0013] The advantages of the above technical solution are: by setting the first and second abutment pieces in the hollow cavity, an effective elastic support limit is formed for the lock hook, so that the lock hook slides smoothly in the heart-shaped lock groove of the button and has a good operating feel.
[0014] Furthermore, the left side wall of the second sliding cavity is provided with an installation cavity, the installation groove is provided through at the lower end for installing the connector, and the left and right sides of the connector are also bent to form side plates.
[0015] The advantages of the above technical solution are as follows: by setting up an installation cavity, the installation stability of the connector in the second sliding cavity is improved; by setting up a side plate, interference between the locking hook and the installation cavity is avoided; the overall structure is reasonably designed; and during installation, the connector with the locking hook is inserted into the installation cavity from the bottom side of the upper shell, and then the base is installed. After assembly, the problem of the connector falling off can be effectively prevented.
[0016] Furthermore, the lower end of the upper shell is provided with a mounting ring edge, and the mounting ring edge is also symmetrically provided with a locking slot. The peripheral wall surface of the base is symmetrically provided with locking blocks, and the locking blocks cooperate with the locking slots.
[0017] The advantages of the above technical solution are: the base and the upper shell can be snapped together by the cooperation of the locking block and the locking slot, making installation convenient.
[0018] Furthermore, anti-rotation grooves are provided between the card blocks, and anti-rotation protrusions are provided on the peripheral wall of the base, the anti-rotation protrusions being adapted to the anti-rotation grooves.
[0019] The advantages of adopting the above technical solution are: by cooperating with the anti-rotation groove and the anti-rotation protrusion, the circumferential rotation of the base can be restricted, thereby ensuring the positional accuracy of the stationary contact, making the cooperation safer, and preventing the problem of the block coming out.
