Description

Technical Field

[0001] This application relates to the technical field of time control switches, and in particular to a time control switch that prevents accidental activation. Background Technology

[0002] A time switch is a power switch control device composed of a single-chip microprocessor as its core and electronic circuits. The time switch can automatically control the on and off of the circuit according to a preset time. It is widely used in various scenarios and can be used under a rated current of 40 amps. 40-amp time switches are often used to control relatively small electrical equipment.

[0003] In related technologies, a time-controlled switch includes an upper shell and a lower shell, with electrical components between the upper and lower shells. These electrical components enable the basic functions of the time-controlled switch. The upper shell has multiple buttons, which control the electrical components to automatically switch the control circuit on and off. The upper shell has bolts and through holes, while the lower shell has threaded holes. The bolts pass through the through holes and are threaded into the threaded holes, thus fixing the upper and lower shells together.

[0004] Because the button is located on the upper shell, people are prone to accidentally pressing it, which can cause problems with the on / off timing of the time switch control circuit and affect the normal use of the time switch. Summary of the Invention

[0005] To address the issue of accidental activation of time switches, this application provides a time switch designed to prevent accidental activation.

[0006] This application provides a time control switch to prevent accidental activation, which adopts the following technical solution:

[0007] A time control switch designed to prevent accidental activation includes an upper shell and a lower shell. The upper shell has a button, and a protective cover is rotatably connected to the upper shell to cover the button.

[0008] By adopting the above technical solution, the button is covered by a protective cover, which protects the button and prevents people from directly touching it, reducing the possibility of accidental button touch. This allows the time switch to stably control the circuit's on / off time and ensures the time switch can be used normally.

[0009] Optionally, the lower shell has a fixing groove, the fixing groove has a stop groove, the upper shell has a fixing strip for inserting into the fixing groove, the fixing strip has a stop strip slidably connected to it, and the fixing strip has a stop rod for driving the stop strip into the stop groove. When the stop strip is inserted into the stop groove, the upper shell and the lower shell are fixed to each other.

[0010] By adopting the above technical solution, the stop bar is driven by the stop rod to slide on the fixed bar, so that the stop bar is inserted into the stop groove. The groove wall of the stop groove limits the stop bar, so that the stop bar can limit the lower shell and fix the upper shell and the lower shell to each other. Compared with the bolt connection in the background technology, the sliding stop bar is simpler and can be achieved without the use of other tools, so that the staff can disassemble the time control switch without the use of tools.

[0011] Optionally, the fixing strip has a through hole, and a stop rod is slidably connected in the through hole. The surface of the stop rod facing the stop strip is inclined, and the inclined surface is used to drive the stop strip to move in the direction of the stop groove. When the stop rod is fully inserted into the through hole, the stop strip is located in the stop groove.

[0012] By adopting the above technical solution, the surface of the stop rod facing the stop strip is inclined. The stop rod drives the stop strip to move towards the stop groove through the inclined surface. People insert the stop rod completely into the perforation, so that the stop strip is inserted into the stop groove, thereby fixing the upper shell and the lower shell together.

[0013] Optionally, the upper shell is provided with a fixing spring, and the fixing spring is provided with a fixing cover, which drives the fixing cover to seal the perforation.

[0014] By adopting the above technical solution, the fixed cover is moved by the fixed spring, and the fixed cover seals the perforation. This prevents the stop rod from detaching from the perforation, thereby further strengthening the limit on the stop rod, reducing the possibility of the stop strip detaching from the stop groove, and making the stop strip more stable in the stop groove.

[0015] Optionally, the protective cover is provided with a drive gear, and the upper shell is rotatably connected with a driven gear set. The drive gear meshes with the driven gear set, and a limit strip is slidably connected to the upper shell. The limit strip meshes with the driven gear set. When the protective cover covers the button, the limit strip can block the perforation.

[0016] By adopting the above technical solution, when people rotate the protective cover, the driving gear on the protective cover rotates. Since the driving gear meshes with the driven gear set, the driven gear set rotates together with the driving gear. Since the limiting strip meshes with the driven gear set, the limiting strip can slide, allowing the limiting strip to block the perforation and limit the stop rod, further strengthening the fixation of the stop rod within the perforation. When the protective cover covers the button, the limiting strip blocks the perforation, allowing the limiting strip to block the perforation for a long time, reducing the possibility of the stop rod detaching from the perforation. Furthermore, when the protective cover does not cover the button, the staff generally need to operate the button, so the staff can notice the stop rod detaching from the perforation and allow the detached stop rod to re-insert into the perforation.

[0017] Optionally, the fixed cover has a limiting groove for the insertion of the limiting strip. When the limiting strip is inserted into the limiting groove, the protective cover does not cover the button; when the fixed cover does not block the through hole, the limiting groove is not in the movement path of the limiting strip.

[0018] By adopting the above technical solution, when the protective cover does not cover the button, the protective cover drives the limiting strip to move through the active gear and driven gear set, allowing the limiting strip to insert into the limiting groove, thereby limiting the fixed cover. This ensures that the fixed cover can stably block the perforation, reducing the possibility of the limiting rod detaching from the perforation and making the upper and lower shells more securely fixed. When the protective cover does not cover the button, people can check whether the fixed cover blocks the perforation. If the limiting strip does not block the perforation, the limiting groove is not in the sliding path of the limiting strip, and the limiting strip cannot be inserted into the limiting groove. This allows people to check whether the upper and lower shells are fixed while opening the protective cover. If the upper and lower shells are not securely fixed, people can manually fix the fixed cover.

[0019] Optionally, a retaining plate is slidably connected to the upper shell, and the retaining plate is located on the moving path of the protective cover. When the protective cover abuts against the retaining plate, the limiting strip does not block the perforation.

[0020] By adopting the above technical solution, the clamping plate is located on the moving path of the protective cover, so that the clamping plate limits the movement of the protective cover, preventing the protective cover from continuing to drive the limit strip to move. This keeps the limit strip in an unsealed perforation state, allowing the staff to move the fixed cover more conveniently, so that the stop rod can disengage from the perforation, the stop strip can disengage from the stop groove, and the upper shell and lower shell can be separated.

[0021] Optionally, the stop bar is provided with a movable spring, which drives the stop bar to disengage from the stop groove.

[0022] By adopting the above technical solution, the stop bar is driven to disengage from the stop groove by the moving spring. When the stop rod disengages from the perforation, the stop bar can disengage from the stop groove under the drive of the moving spring, so that the stop bar does not limit the stop groove, thus facilitating the separation of the upper and lower shells.

[0023] Optionally, the fixed cover has an operating hole for the stop rod to pass through, and an operating rod is slidably connected in the operating hole. When the stop rod is inserted into the operating hole, the operating rod protrudes from the fixed cover, and at this time the stop strip is located in the stop groove.

[0024] By adopting the above technical solution, the stop rod is inserted into the perforation, and the moving spring drives the stop strip to push the stop rod. The stop rod is inserted into the operating hole, so that the operating rod protrudes from the operating hole. This allows people to observe the position of the operating rod to know whether there is a stop rod in the perforation, thus avoiding the situation where the upper and lower shells are not securely fixed due to the stop rod not being placed.

[0025] Optionally, the protective cover has an operating groove, and when the operating lever is inserted into the operating groove, the protective cover does not cover the button.

[0026] By adopting the above technical solution, the operating rod is inserted into the operating slot, allowing the operating rod to limit the protective cover. That is, the protective cover can be fixed when it does not cover the button, so that the operator can press the button. At the same time, when the protective cover does not cover the button, the protruding operating rod limits the protective cover. If the protective cover is not limited, the operator can know that the fixation between the upper and lower shells is not secure, so that the operator can re-fix the upper and lower shells.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By covering the button with a protective cover, the button is protected to prevent people from directly touching it, reducing the possibility of accidental button activation. This allows the time switch to stably control the circuit's on / off time and ensures the time switch can be used normally.

[0029] 2. When people rotate the protective cover, the drive gear on the cover rotates. Since the drive gear meshes with the driven gear set, the driven gear set rotates along with the drive gear. Because the limiting strip meshes with the driven gear set, the limiting strip can slide, allowing it to block the perforation and limit the stop rod, further strengthening the fixation of the stop rod within the perforation. When the protective cover covers the button, the limiting strip blocks the perforation, ensuring long-term sealing and reducing the possibility of the stop rod detaching from the perforation. Furthermore, when the protective cover is not covering the button, staff generally need to operate the button, thus preventing the stop rod from detaching from the perforation.

[0030] 3. When the protective cover is not covering the button, the protective cover drives the limiting strip to move through the drive gear and driven gear set, allowing the limiting strip to insert into the limiting groove. This limits the fixed cover, ensuring that the fixed cover can stably block the perforation, reducing the possibility of the limiting rod detaching from the perforation, and making the upper and lower shells more securely fixed. When the protective cover is not covering the button, people can check whether the fixed cover is blocking the perforation. If the limiting strip is not blocking the perforation, the limiting groove is not in the sliding path of the limiting strip. This allows people to check whether the upper and lower shells are fixed while opening the protective cover. If the fixation is not secure, people can manually position the fixed cover.

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This embodiment discloses a time-controlled switch to prevent accidental activation. (Refer to...) Figure 1 and Figure 2 A time control switch designed to prevent accidental touches includes an upper shell 1 and a lower shell 2. The upper shell 1 is equipped with a display screen and multiple buttons 11. Electrical components are installed inside the upper shell 1. The buttons 11 control the electrical components to achieve automatic control of the circuit's on / off state.

[0040] Reference Figure 3 A fixing groove 21 is formed on the surface of the lower shell 2, and a stop groove 22 is formed on the groove wall of the fixing groove 21. The stop groove 22 does not penetrate to the surface of the lower shell 2 where the fixing groove 21 is formed. A fixing hole 12 is formed on the surface of the upper shell 1, and a fixing strip 121 is fixedly connected in the fixing hole 12. The fixing strip 121 can be inserted into the fixing groove 21.

[0041] Reference Figure 4A movable groove 122 is formed on the outer surface of the fixing strip 121, extending along a length direction perpendicular to the fixing strip 121. A stop strip 123 is slidably connected within the movable groove 122, and the stop strip 123 can be inserted into the stop groove 122. Two movable springs 124 are provided within the movable groove 122, one end of which is fixedly connected to the bottom wall of the movable groove 122, and the other end of which is fixedly connected to the stop strip 123. When the stop strip 123 is inserted into the stop groove 22, the movable spring 124 is in a stretched state. When the stop strip 123 is located within the movable groove 122, the movable spring 124 is in a non-stressed state; when the stop strip 123 is located within the stop groove 22, the movable spring 124 is in a stretched state.

[0042] Reference Figure 4 A through hole 125, connecting to a movable groove 122, is provided on the end face of the fixing strip 121, extending along the length of the fixing strip 121. A stop rod 126 is slidably connected within the through hole 125, extending along the length of the fixing strip 121. The end face of the stop rod 126 facing the lower shell 2 has an inclined surface 127, which slopes between the stop groove 22 and the upper shell 1. The stop rod 126 can extend between two movable springs 124, and the stop rod 126 drives the stop strip 123 to protrude out of the stop groove 22 via the inclined surface 127. When the stop rod 126 is fully inserted into the through hole 125, the stop rod 126 drives the stop strip 123 to move via the inclined surface 127, allowing the stop strip 123 to insert into the stop groove 22, thus fixing the upper shell 1 and the lower shell 2 together.

[0043] Reference Figure 4 A receiving groove 13 communicating with the fixing hole 12 is formed on the hole wall, and a fixing spring 131 is installed in the receiving groove 13. One end of the fixing spring 131 is fixedly connected to the bottom wall of the receiving groove 13, and the other end of the fixing spring 131 is fixedly connected to a fixing cap 132, which can block the opening of the fixing hole 12. When the fixing cap 132 blocks the fixing hole 12, the fixing spring 131 is in a non-stressed state. When the fixing cap 132 does not block the through hole 125, the fixing spring 131 is in a compressed state.

[0044] Reference Figure 4 An operating hole 133 is provided on the surface of the fixed cover 132, and the operating hole 133 extends vertically. An operating rod 134 is slidably connected in the operating hole 133, and the operating hole 133 allows a stop rod 126 to be inserted. When the stop rod 126 is inserted into the operating hole 133, the stop rod 126 abuts against the operating rod 134, causing the operating rod 134 to protrude from the fixed cover 132.

[0045] Reference Figure 4When the stop rod 126 is inserted into the through hole 125, the stop rod 126 drives the stop strip 123 to be inserted into the stop groove 22. The fixing spring 131 drives the fixing cover 132 to block the through hole 125. At this time, the moving spring 124 drives the stop strip 123 to move towards the bottom wall of the moving groove 122, and the stop strip 123 does not leave the stop groove 22. The stop strip 123 drives the stop rod 126 to protrude towards the operating hole 133. The stop rod 126 is inserted into the operating hole 133. At this time, the operating rod 134 is driven by the stop rod 126 to protrude from the fixing cover 132, so that people can check whether the upper and lower shells 2 are fixed to each other.

[0046] Reference Figure 2 A rotating rod 3 is fixedly connected to the upper shell 1, and a protective cover 31 is rotatably connected to the rotating rod 3. The protective cover 31 can cover the button 11 to prevent people from accidentally touching the button 11. Two torsion springs 32 are sleeved on the rotating rod 3. One end of the torsion spring 32 abuts against the upper shell 1, and the other end of the torsion spring 32 abuts against the protective cover 31. The torsion spring 32 can drive the protective cover 31 to cover the button 11.

[0047] Reference Figure 5 A drive gear 35 is fixedly connected to the protective cover 31, and the drive gear 35 is rotatably connected to the rotating rod 3. A gear groove 36 is provided on the upper shell 1, and a driven gear set 361 is rotatably connected within the gear groove 36. The driven gear set 361 includes multiple rotating gears, which are rotatably connected within the gear groove 36 and distributed along the length of the gear groove 36. Adjacent rotating gears mesh with each other, and the rotating gear closest to the drive gear 35 meshes with the drive gear 35. When the drive gear 35 rotates, it can drive the rotating gears to rotate.

[0048] Reference Figure 4 and Figure 6 The upper shell 1 has a through hole 33 that connects to the gear groove 36 and the fixing hole 12. A limit strip 331 is slidably connected in the through hole 33, and the limit strip 331 meshes with the driven gear set 361. The side of the fixing strip 121 has a limit hole 128 for the insertion of the limit strip 331, and the side of the fixing cover 132 has a limit groove 135 for the insertion of the limit strip 331. When the limit strip 331 passes through the limit hole 128 and is inserted into the limit groove 135, the fixing cover 132 completely seals the fixing hole 12. When the limit groove 135 is not on the movement path of the limit strip 331, the fixing cover 132 does not completely seal the fixing hole 12.

[0049] Reference Figure 5Rotate the protective cover 31 to cover the button 11. The drive gear 35 of the protective cover 31 rotates, which drives the driven gear set 361 to rotate. The driven gear set 361 drives the limiting strip 331 to move in the through hole 33, so that the limiting strip 331 can be inserted into the limiting groove 135, thereby further fixing the fixed cover 132 and detecting the fixing status of the fixed cover 132.

[0050] Reference Figure 2 The protective cover 31 has an operating groove 34 on its surface for inserting the operating lever 134. The operating lever 134 is elastic. The protective cover 31 is rotated so that the operating lever 134 is inserted into the operating groove 34. At this time, the protective cover 31 does not cover the button 11 so that people can press the button 11.

[0051] Reference Figure 2 and Figure 6 A retaining plate 14 is slidably connected to the upper shell 1. The retaining plate 14 is located in the rotation path of the protective cover 31 toward the button 11. When the retaining plate 14 protrudes from the upper shell 1, the retaining plate 14 restricts the protective cover 31 from continuing to rotate toward the button 11. At this time, the limiting strip 331 is not inserted into the limiting groove 135, and the operating rod 134 is not inserted into the operating groove 34, so that the operator can disassemble the upper shell 1 and the lower shell 2.

[0052] The implementation principle of the time control switch for preventing accidental touch in this application embodiment is as follows: When a stop rod 126 is inserted into the through hole 125, the stop rod 126 drives the stop strip 123 to be inserted into the stop groove 22 through the inclined surface 127. At this time, the fixed spring 131 drives the fixed cover 132 to block the through hole 125, and the moving spring 124 drives the stop strip 123 to move away from the stop groove 22, so that the stop strip 123 drives the stop rod 126 to be inserted into the operation hole 133 through the inclined surface 127, so that the operation rod 134 protrudes from the fixed cover 132.
