Description

Technical Field

[0001] This application relates to the technical field of switches, and in particular to a jog rotary switch. Background Technology

[0002] A momentary rotary switch is a composite switch that integrates a selector and an instant start button. It selects from multiple options by rotating the switch and is widely used due to its high safety and high degree of functional integration.

[0003] In related technologies, a jog rotary switch includes a housing, a rotating shaft mounted on the housing, a swivel block mounted on the rotating shaft, a moving piece mounted on the swivel block, and multiple stationary pieces mounted within the housing. The moving piece is annular with protrusions along its edges. The swivel block has several notches for the moving piece. During installation, the moving piece is first placed against the swivel block, then the protrusions of the moving piece are bent and inserted into the notches, and finally, the protrusions are bent and placed against the other side of the swivel block to achieve a stable connection between the moving piece and the swivel block. In use, rotating the rotating shaft causes the swivel block and the moving piece to rotate, causing the moving piece to contact different stationary pieces, thus switching the electrical connection between the stationary pieces and performing a switching function, such as controlling the forward and reverse rotation of a juicer.

[0004] However, the installation process of the moving piece and the swivel piece of the above-mentioned jog rotary switch is complicated, resulting in low assembly efficiency of the jog rotary switch, and therefore needs to be improved. Utility Model Content

[0005] In order to improve the production efficiency of jog rotary switches, this application provides a jog rotary switch.

[0006] The jog rotary switch provided in this application adopts the following technical solution: A jog rotary switch includes a housing, a rotating shaft mounted on the housing, a cloverleaf block mounted on the rotating shaft, a moving piece mounted on the cloverleaf block, and multiple stationary pieces mounted in the housing. The cloverleaf block is provided with a fixing seat, and the fixing seat is provided with several mounting slots. The moving piece is arc-shaped, and both ends of the moving piece are provided with fixing blocks, which are engaged in the mounting slots.

[0007] By adopting the above technical solution, when installing the pentatonic block and the moving piece, it is only necessary to insert the fixing blocks at both ends of the moving piece into the mounting groove. There is no need for complex installation procedures such as stamping or bending of the moving piece, simplifying the operation and improving the assembly efficiency of the jog rotary switch. Furthermore, the moving piece can be mass-produced using the same mold, increasing production efficiency.

[0008] Optionally, the fixing block at one end of the moving piece is arc-shaped and the fixing block at the other end is square. The mounting groove includes an arc-shaped groove for the arc-shaped fixing block to extend into and a square groove for the square fixing block to extend into. There are two arc-shaped grooves and two square grooves arranged adjacent to each other.

[0009] By adopting the above technical solution, when the moving piece is inserted into the mounting slot, it can only enter the mounting slot in a fixed posture. That is, the arc-shaped fixing block cannot be inserted into the square slot, and the square fixing block cannot be inserted into the arc-shaped slot. Moreover, the mounting positions of the fixing blocks at both ends of the moving piece are fixed, ensuring that the two ends can always connect to the same set of stationary pieces when the moving piece rotates. This reduces the possibility of workers misinstalling the moving piece, improves the accuracy and consistency of installation, ensures the production quality of the jog rotary switch, and thus ensures the safety of the jog rotary switch in use.

[0010] Optionally, the outer casing includes a bottom box and a top cover, the movable piece is disposed on the side of the plum blossom block away from the top cover, a limiting block is provided on the bottom wall of the bottom box, the movable piece abuts between the limiting block and the plum blossom block, and the limiting block is in the same arc shape as the movable piece.

[0011] By adopting the above technical solution, when installing the moving piece and the pentagonal block, the fixing block of the moving piece is first inserted into the mounting groove, and then the pentagonal block and the moving piece are placed together in the bottom box, so that the side of the moving piece away from the pentagonal block abuts against the limiting block, thereby preventing the moving piece from moving away from the pentagonal block and improving the stability of the moving piece. The limiting block is arc-shaped with the same shape as the moving piece, so that the contact area between the moving piece and the limiting block is large, thereby making the limiting block have a good limiting effect on the moving piece, effectively reducing the possibility of the moving piece shifting or falling off during rotation, enhancing the structural stability and contact reliability of the jog rotary switch, and extending the service life of the jog rotary switch.

[0012] Optionally, the bottom box extends into the top cover, the side wall of the bottom box is provided with a snap-fit ​​block, the top cover is provided with a fixing hole, the snap-fit ​​block is provided with a guide slope, and the guide slope is used to guide the snap-fit ​​block into the fixing hole.

[0013] By adopting the above technical solution, when the top cover needs to be assembled onto the bottom box, simply insert the bottom box into the top cover so that the guide slope abuts against the wall of the fixing hole, and then push the top cover toward the side closer to the bottom box so that the snap-fit ​​block inserts into the fixing hole. The operation is simple, realizes the quick alignment and snap-fit ​​assembly of the shell, simplifies the assembly process of the shell, further improves production efficiency, and enhances the structural strength and sealing of the shell.

[0014] Optionally, the plum blossom block has a relief groove at the connection between the two ends of the moving piece, and the relief groove is used to allow the stationary piece to extend in.

[0015] By adopting the above technical solution, when the moving piece rotates to the position of contacting the stationary piece, a part of the stationary piece can extend into the clearance groove, which reduces the possibility of poor contact between the stationary piece and the moving piece caused by the side wall of the quincunx block colliding with the stationary piece, improves the connection stability between the stationary piece and the moving piece, thereby ensuring the accuracy and stability of electrical contact, and improving the electrical performance and safety of the switch.

[0016] Optionally, the moving plate has connecting grooves at both ends for the stationary plate to extend into.

[0017] By adopting the above technical solution, when the stationary piece and the moving piece come into contact, the stationary piece will extend into the connecting groove, making it difficult for the stationary piece and the moving piece to move relative to each other, thereby further improving the connection stability of the stationary piece and the moving piece.

[0018] Optionally, the rotating shaft is provided with a reset torsion spring, which has the tendency to drive the rotating shaft back to its initial position.

[0019] By adopting the above technical solution, after the rotating shaft makes the moving plate and the stationary plate contact and connect the circuit, once the hand is released, the rotating shaft will automatically reset under the action of the reset torsion spring, reducing safety accidents caused by forgetting to turn off the switch and improving the safety when using the jog rotary switch.

[0020] Optionally, a conductive sheet is connected to the stationary plate, and a wiring hole is provided on the bottom box for the conductive sheet to extend out of the outer shell.

[0021] By adopting the above technical solution, when the jog rotary switch needs to be connected to the actual circuit, it is only necessary to connect the external power supply wire to the conductive plate. There is no need to extend the wire into the shell for wiring. The operation is convenient, and it is easy to connect the jog rotary switch to the external circuit. This improves the wiring efficiency of the jog rotary switch, thereby improving the wiring quality and ensuring the neatness and safety of the leads.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By snapping the moving piece into the mounting slot and setting a limit block on the bottom box to limit the moving piece, the installation steps of the moving piece and the plum blossom block are simplified, eliminating the need for stamping, bending or other processes on the moving piece, thus improving the installation efficiency of the jog rotary switch. 2. The shape and position design of the mounting slot makes the fault tolerance rate of the moving part installation higher. The moving part can only be installed in a fixed posture, which reduces the probability of workers misinstalling and improves the production quality of the jog rotary switch. 3. The plum blossom block is provided with a relief groove for the stationary piece to extend into, so that the side wall of the plum blossom block is less likely to block the stationary piece from contacting the moving piece, thereby making the contact between the stationary piece and the moving piece tighter and improving the stability of the electrical connection between the stationary piece and the moving piece.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a jog rotary switch.

[0030] Reference Figure 1 and Figure 2 A jog rotary switch includes a housing 1, a rotating shaft 2, a swivel block 3, a moving piece 4, and multiple stationary pieces 5. The rotating shaft 2 is mounted on the housing 1, the swivel block 3 is mounted on the rotating shaft 2, the moving piece 4 is mounted on the swivel block 3, and the multiple stationary pieces 5 are disposed within the housing 1. The housing 1 includes a base box 11 and a top cover 12. With this arrangement, rotating the rotating shaft 2 drives the swivel block 3 and the moving piece 4 to rotate, causing the moving piece 4 to contact different stationary pieces 5, thereby achieving the switching of electrical connections between the stationary pieces 5.

[0031] Reference Figure 2 A reset torsion spring 21 is sleeved on the rotating shaft 2. The reset torsion spring 21 has the tendency to drive the rotating shaft 2 back to the initial position. When the rotating shaft 2 is rotated and the hand is released, the reset torsion spring 21 will cause the rotating shaft 2 to return to its original position, realizing the automatic reset of the moving piece 4, which is convenient for the next operation.

[0032] Reference Figure 3The plum blossom block 3 is provided with a fixed seat 31, and the fixed seat 31 is provided with several mounting slots 311. The moving piece 4 is arc-shaped, and both ends of the moving piece 4 are provided with fixed blocks 41. The fixed blocks 41 are snapped into the mounting slots 311. This snapping method replaces the traditional bending and fitting installation method, which greatly simplifies the installation process of the moving piece 4 and the plum blossom block 3 and improves the assembly efficiency of the jog rotary switch.

[0033] Reference Figure 3 The mounting groove 311 includes an arc-shaped groove 312 and a square groove 313. The arc-shaped groove 312 is designed to accommodate the arc-shaped fixing block 41 at one end of the moving piece 4. Its shape matches the arc-shaped fixing block 41 and can hold the arc-shaped fixing block 41 in place. There are two arc-shaped grooves 312, which are arranged adjacent to each other.

[0034] Reference Figure 3 The square groove 313 is designed to accommodate the square-shaped fixing block 41 at the other end of the moving piece 4. Two square grooves are also provided, arranged adjacent to each other. The mounting groove 311 can be created using machining methods such as milling to ensure the groove's precision and dimensional accuracy.

[0035] Reference Figure 3 The movable piece 4 is an arc-shaped sheet structure, usually made of a metal material with good electrical conductivity, such as copper. The fixing blocks 41 at both ends of the movable piece 4 are arc-shaped at one end and square at the other. This design with different shapes reduces the possibility of incorrect installation of the movable piece 4 and serves to fix its installation position. The fixing blocks 41 and the movable piece 4 can be integrally formed.

[0036] Reference Figure 3 and Figure 4 A limiting block 113 is provided on the bottom wall of the base box 11. The limiting block 113 is arc-shaped like the moving piece 4. The function of the limiting block 113 is to restrict the position of the moving piece 4, so that the moving piece 4 abuts between the limiting block 113 and the plum blossom block 3, ensuring the stability of the moving piece 4 during rotation.

[0037] Reference Figure 2 and Figure 3 The plum blossom block 3 has clearance grooves 32 at both ends of the moving piece 4. These grooves allow the stationary piece 5 to extend into the grooves, reducing the possibility of interference between the stationary piece 5 and the sidewall of the plum blossom block 3, and ensuring that the stationary piece 5 can make normal contact with the moving piece 4. The moving piece 4 has connecting grooves 42 at both ends of the moving piece 4. These grooves allow the stationary piece 5 to extend into the moving piece 4, making the contact between the stationary piece 5 and the moving piece 4 tighter, thereby improving the stability of the electrical connection.

[0038] Reference Figure 3 and Figure 4A conductive sheet 51 is connected to the stationary plate 5. The conductive sheet 51 is a sheet-like structure made of a metal material with good conductivity, such as copper. A wiring hole 114 is provided on the bottom box 11, which allows the conductive sheet 51 to extend out of the outer shell 1, facilitating the connection between the stationary plate 5 and an external circuit. The connection between the conductive sheet 51 and the stationary plate 5 can be achieved by welding or other methods to ensure good conductivity.

[0039] Reference Figure 3 and Figure 4 The base box 11 is a box structure with a bottom, generally made of insulating materials such as plastic. Its shape can be designed according to actual needs, such as square or round. The top cover 12 is a cover used to cover the base box 11. The design of the base box 11 and the top cover 12 can protect the internal components and prevent external dust, moisture, etc. from entering the inching rotary switch.

[0040] Reference Figure 3 and Figure 4 The bottom box 11 has a snap-fit ​​block 111 on its side wall, and the top cover 12 has a fixing hole 121. The snap-fit ​​block 111 has a guide slope 112. When the bottom box 11 is inserted into the top cover 12, the guide slope 112 can guide the snap-fit ​​block 111 to smoothly extend into the fixing hole 121, thereby achieving the snap-fit ​​fixation between the bottom box 11 and the top cover 12. This snap-fit ​​method makes the assembly of the outer shell 1 more convenient and faster.

[0041] The implementation principle of the jog rotary switch in this application embodiment is as follows: When assembling the jog rotary switch, simply align the fixing blocks 41 at both ends of the moving piece 4 with the corresponding mounting slots 311, then press the moving piece 4 so that the fixing blocks 41 are inserted into the mounting slots 311, then place the plum blossom block 3 in the bottom box 11 so that the moving piece 4 is clamped between the limiting block 113 and the plum blossom block 3, and finally snap the top cover 12 onto the bottom box 11. The operation is simple, the assembly process is simplified, and the assembly efficiency of the jog rotary switch is improved.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
