Technical Field

[0001] The present application relates to the technical field of time-controlled switches, and in particular to a time-controlled switch capable of preventing accidental touches. Background Art

[0002] The time switch is a power switch control device with a single-chip microprocessor as the core and electronic circuits. The time switch can automatically control the on and off of the circuit according to the preset time. It is widely used in various scenarios. The time switch can be used at a rated current of 40 amperes. The 40 ampere time switch is often used to control relatively small electrical equipment.

[0003] In the related technology, the time-controlled switch includes an upper shell and a lower shell, and an electrical component is arranged between the upper shell and the lower shell. The electrical component can realize the basic functions of the time-controlled switch. A plurality of buttons are arranged on the upper shell, and the buttons realize automatic on and off of the control circuit by controlling the electrical components. Bolts are arranged on the upper shell, a through hole is opened on the upper shell, and a threaded hole is opened on the lower shell. The bolts pass through the through hole and are threadedly connected to the threaded hole to realize mutual fixation of the upper shell and the lower shell.

[0004] Since the button is arranged on the upper shell, people may easily touch the button by mistake in normal times, which may cause problems in the on-off time of the time-controlled switch control circuit, thus affecting the normal use of the time-controlled switch. Summary of the invention

[0005] In order to improve the problem that a time switch is easily accidentally touched, the present application provides a time switch that prevents accidental touching.

[0006] The present application provides a time-controlled switch for preventing accidental touch, which adopts the following technical solution: A time-controlled switch for preventing accidental touch comprises an upper shell and a lower shell. The upper shell is provided with a button. A protective cover is rotatably connected to the upper shell, and the protective cover is used to cover the button.

[0007] By adopting the above technical solution, the button is covered by a protective cover so that the button is protected by the protective cover to prevent people from directly touching the button, thereby reducing the possibility of people accidentally touching the button in normal times, so that the time switch can stably control the on and off time of the circuit and the time switch can be used normally.

[0008] Optionally, a fixing groove is provided on the lower shell, a stopping groove is provided on the fixing groove, a fixing strip for inserting into the fixing groove is provided on the upper shell, a stopping strip is slidably connected to the fixing strip, and a stopping rod for driving the stopping strip to insert into the stopping groove is provided on the fixing strip; when the stopping strip is inserted into the stopping groove, the upper shell and the lower shell are fixed to each other.

[0009] 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, and the groove wall of the stop groove limits the stop bar, so that the stop bar can limit the lower shell, so that the upper shell and the lower shell are fixed to each other. Compared with the bolt connection in the background technology, the sliding stop bar is relatively simple and can be achieved without the use of other tools, so that the staff does not need to use tools when disassembling the time control switch.

[0010] Optionally, a through hole is provided on the fixing bar, and a stop rod is slidably connected in the through hole. The surface of the stop rod facing the stop bar is a slope, and the slope is used to drive the stop bar to move toward the stop groove. When the stop rod is fully inserted into the through hole, the stop bar is located in the stop groove.

[0011] By adopting the above technical solution, the surface of the stop rod facing the stop strip is an inclined surface, and the stop rod drives the stop strip to move toward the stop groove through the inclined surface. People insert the stop rod completely into the through hole to insert the stop strip into the stop groove, thereby fixing the upper shell and the lower shell to each other.

[0012] Optionally, a fixing spring is provided on the upper shell, a fixing cover is provided on the fixing spring, and the fixing spring drives the fixing cover to seal the perforation.

[0013] By adopting the above technical solution, the fixed cover is driven to move by the fixed spring, so that the fixed cover blocks the perforation, so that the fixed cover restricts the stop rod from detaching from the perforation, thereby further strengthening the limit of the stop rod, reducing the possibility of the stop bar detaching from the stop groove, and making the stop bar more stable in the stop groove.

[0014] Optionally, a driving gear is provided on the protective cover, a driven gear set is rotatably connected to the upper shell, the driving gear is meshed with the driven gear set, a limiting strip is slidably connected to the upper shell, the limiting strip is meshed with the driven gear set, and when the protective cover covers the button, the limiting strip can block the perforation.

[0015] By adopting the above technical solution, when people rotate the protective cover, the active gear on the protective cover rotates, and since the active gear is meshed with the driven gear set, the driven gear set rotates together with the active gear, and since the limit bar is meshed with the driven gear set, the limit bar can slide, so that the limit bar can block the through-hole, thereby realizing the limiting of the stop rod by the limit bar, and further strengthening the degree of fixation of the stop rod in the through-hole; when the protective cover covers the button, the limit bar blocks the through-hole, so that the limit bar can block the through-hole for a long time, reducing the possibility of the stop rod detaching from the through-hole, and when the protective cover does not cover the button, the staff generally needs to operate the button, so the staff can notice that the stop rod detaches from the through-hole, and let the detached stop rod be inserted into the through-hole.

[0016] Optionally, a limiting groove for inserting a limiting strip is provided on the fixed cover, and 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 moving path of the limiting strip.

[0017] By adopting the above technical solution, when the protective cover does not cover the button, the protective cover drives the limit bar to move through the active gear and the driven gear set, so that the limit bar is inserted into the limit groove, so that the limit bar limits the fixed cover, so that the fixed cover can stably block the perforation, reducing the possibility of the limit rod detaching from the perforation, making the upper shell and the lower shell more securely fixed; when the protective cover does not cover the button, people can check whether the fixed cover blocks the perforation. If the limit bar does not block the perforation, the limit groove is not in the sliding path of the limit bar, and the limit bar cannot be inserted into the limit groove, so that people can check whether the upper shell and the lower shell are fixed while opening the protective cover. If the upper shell and the lower shell are not securely fixed, people can manually fix the fixed cover.

[0018] Optionally, a card plate is slidably connected to the upper shell, and the card plate is located on the moving path of the protective cover. When the protective cover abuts against the card plate, the limit strip does not block the through hole.

[0019] By adopting the above technical solution, the card plate is located on the moving path of the protective cover, so that the card plate limits the protective cover, so that the protective cover cannot continue to drive the limit bar to move, and the limit bar is in a state of unblocking the perforation, so that the staff can more conveniently move the fixed cover, realize the detachment of the stop rod from the perforation, and the detachment of the stop bar from the stop groove, thereby realizing the separation of the upper shell and the lower shell.

[0020] Optionally, a movable spring is provided on the stop bar, and the movable spring drives the stop bar to disengage from the stop groove.

[0021] By adopting the above technical solution, the stop strip is driven to disengage from the stop groove by the moving spring. When the stop rod is disengaged from the perforation, the stop strip can be driven to disengage from the stop groove by the moving spring, so that the stop strip does not limit the stop groove, thereby facilitating the separation of the upper shell and the lower shell.

[0022] Optionally, an operating hole for a stop rod to pass through is opened on the fixed cover, 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 the stop bar is located in the stop groove.

[0023] By adopting the above technical solution, the stop rod is inserted into the through hole, and the movable spring drives the stop bar to push the stop rod, and the stop rod is inserted into the operating hole, so that the operating rod protrudes from the operating hole, so that people can observe the position of the operating rod to know whether there is a stop rod in the through hole, thereby avoiding the situation where the stop rod is not placed and the upper shell and the lower shell are not firmly fixed.

[0024] Optionally, an operating slot is provided on the protective cover, and when the operating rod is inserted into the operating slot, the protective cover does not cover the button.

[0025] By adopting the above technical solution, the operating rod is inserted into the operating groove so that the operating rod can limit the protective cover, that is, the protective cover can be fixed when it does not cover the button, so that the staff can press the button; at the same time, when the protective cover does not cover the button, the protective cover is limited by the protruding operating rod. If the protective cover is not limited, the staff will know that the fixation between the upper shell and the lower shell is not reliable, so that the staff can re-fix the upper shell and the lower shell.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Cover the button with a protective cover so that the button is protected by the protective cover to prevent people from directly touching the button and reduce the possibility of people accidentally touching the button in normal times, so that the time switch can stably control the on and off time of the circuit and allow the time switch to be used normally.

[0027] 2. When people turn the protective cover, the driving gear on the protective cover rotates. Since the driving gear is meshed with the driven gear set, the driven gear set rotates with the driving gear. Since the limit bar is meshed with the driven gear set, the limit bar can slide, so that the limit bar can block the through-hole, thereby limiting the position of the stop rod by the limit bar, and further strengthening the fixation of the stop rod in the through-hole. When the protective cover covers the button, the limit bar blocks the through-hole, so that the limit bar can block the through-hole for a long time, reducing the possibility of the stop rod detaching from the through-hole. When the protective cover does not cover the button, the staff generally needs to operate the button, so the staff can avoid the stop rod detaching from the through-hole.

[0028] 3. When the protective cover does not cover the button, the protective cover drives the limit bar to move through the active gear and the driven gear set, so that the limit bar is inserted into the limit groove, so that the limit bar limits the fixed cover, so that the fixed cover can stably cover the perforation, reduce the possibility of the limit rod detaching from the perforation, and make the upper shell and the lower shell more securely fixed; when the protective cover does not cover the button, people can check whether the fixed cover blocks the perforation. If the limit bar does not block the perforation, the limit groove is not in the sliding path of the limit bar, so that people can check whether the upper shell and the lower shell are fixed while opening the protective cover. If the fixation is not secure, people can manually position the fixed cover. BRIEF DESCRIPTION OF THE DRAWINGS

Two moving springs 124 are provided in the moving groove 122, one end of the moving spring 124 is fixedly connected to the bottom wall of the moving groove 122, and the other end of the moving spring 124 is fixedly connected to the stop bar 123. When the stop bar 123 is inserted into the stop groove 22, the moving spring 124 is in a stretched state. When the stop bar 123 is located in the moving groove 122, the moving spring 124 is in a non-stressed state; when the stop bar 123 is located in the stop groove 22, the moving spring 124 is in a stretched state.

[0035] Reference Figure 4 The end surface of the fixing strip 121 is provided with a through hole 125 connected to the moving groove 122, and the through hole 125 extends along the length direction of the fixing strip 121. A stop rod 126 is slidably connected in the through hole 125, and the stop rod 126 extends along the length direction of the fixing strip 121. The stop rod 126 has an inclined surface 127 on the end surface facing the lower shell 2, and the inclined surface 127 is inclined between the direction of the stop groove 22 and the direction of the upper shell 1. The stop rod 126 can extend between the two moving springs 124, and the stop rod 126 drives the stop bar 123 to protrude from the stop groove 22 through the inclined surface 127. When people press the stop rod 126 to fully insert it into the through hole 125, the stop rod 126 drives the stop bar 123 to move through the inclined surface 127, so that the stop bar 123 is inserted into the stop groove 22, and the upper shell 1 and the lower shell 2 are fixed to each other.

[0036] Reference Figure 4 The hole wall of the fixing hole 12 is provided with a receiving groove 13 connected to the fixing hole 12, and a fixing spring 131 is provided in the receiving groove 13.
