Description

[0001] Technical control switch field

[0002] The utility model relates to the field of lighting control, in particular to a time-delay switch for lighting control. Background Art

[0003] An indoor switch refers to an electrical switch installed on the wall to connect and disconnect the circuit and control the lighting. In general, indoor switches in households are often installed near the door. After turning off the switch at night, you need to walk a distance to reach the bed, and bumps are inevitable during walking in the dark, which is very inconvenient for older people. A delayed lighting device is more convenient to use.

[0004] At present, the existing delayed light-off switches are mostly push-button switches and touch switches. When the touch switch is in use, the light turns on when the switch range is touched. However, due to the high price of touch switches and the high failure rate in the touch area, the maintenance cost is high. The push-button switch is low-priced and affordable, with low maintenance costs and easy replacement. Compared with the touch switch, it is more convenient and easier to use.

[0005] However, the above-mentioned push-button switch still has shortcomings. Because it is a push-button switch, when installing, it is necessary to fix the switch body in the switch slot reserved in the wall by bolts, pull out the wires and connect them to the power box on the switch, and then install the switch key on the switch body. During installation and disassembly, a screwdriver or a lifting tool is required to disassemble the switch key, and then the bolts are removed to disassemble the switch body. Under the influence of this condition, the push-button switch will be damaged, and it takes a long time for workers to install and disassemble it. Therefore, it is urgently needed to make improvements based on the push-button switch. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a time-delay switch for lighting control to solve the technical problems mentioned in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a light-controlled delay switch, comprising a switch device body, an embedded block fixedly installed at the end of the switch device body, a card block slidably installed in the switch device body, and a protrusion fixedly installed on the outer wall of the switch device body, a card slot corresponding to the card block fixedly installed in the embedded block, and a notch for placing a power cord is opened on the outer wall of the embedded block, and a bolt is rotatably installed on the outer wall of the embedded block, and a mounting block is fixedly installed on the outer wall of the switch device body.

[0008] By adopting the above technical solution, the switch device body is not easy to fall off from the reserved switch slot under the action of the embedding block and the clamping block. Under the action of the mounting block, when the switch device body slides into the switch slot, the rubber characteristics of the mounting block increase the friction between the switch device body and the inner wall of the switch slot when the switch device body is installed in the switch slot, so that the switch device body is firmly installed in the switch slot, thereby making the switch device body easier to install and disassemble, and reducing the time spent on installation and disassembly.

[0009] The utility model is further configured that the embedded block is square in design, the size of the embedded block is consistent with the size of the switch device body, and the bolt one is designed with two symmetrical ones.

[0010] By adopting the above technical solution, the shape of the switch slot and the main body of the switch device is consistent, so that it fits better during installation and is not prone to shaking.

[0011] The utility model is further configured that two card blocks are symmetrically installed on the outer wall of the switch device body, and two card slots are symmetrically installed on the outer wall of the embedded block, and the card block is of "L" shape design.

[0012] By adopting the above technical solution, when the card block is fixed in the slot, the "L"-shaped setting of the card block makes the switch device body tightly connected with the embedded block, so that the switch device body is not easy to slide back and forth and fall off.

[0013] The utility model is further configured that the edge of the end of the switch device body is designed as a bevel.

[0014] By adopting the above technical solution, the switch device body can slide into the switch slot more conveniently and smoothly through the guidance of the inclined surface, so that the switch device body can enter the switch slot more smoothly and reduce the occurrence of jamming.

[0015] The utility model is further configured that the mounting block is triangular in design and is made of rubber.

[0016] By adopting the above technical solution, since the mounting block is made of rubber, when the mounting block is squeezed with the inner wall of the switch slot, the friction and contact area between the switch device body and the inner wall of the switch slot are increased, so that the switch device body is fixed more firmly.

[0017] The utility model is further configured such that the outer wall of the power box is rotatably mounted with two bolts, and a fixing rod is slidably mounted on the outer wall at the end of the power box, and a fixing groove for inserting a power cord is provided on the outer wall of the fixing rod, a pull rope is fixedly mounted on the end of the fixing rod, and a sliding groove for sliding the fixing rod is provided in the power box.

[0018] By adopting the above technical solution, when the electric wire is inserted into the power box, the second bolt is turned so that the power wire is more tightly connected to the power box, so that the power wire can be fixed by turning the second bolt, which saves the time of manually fixing the power wires one by one, making the installation of the power wire more convenient and reducing the time of installing the power wire.

[0019] The utility model is further configured that two fixing rods are symmetrically installed on the outer wall of the power box, and the ratio of the length of the sliding groove to the length of the fixing rod is 1.5:1.

[0020] By adopting the above technical solution, when the fixing rod slides inward, since the length of the sliding groove is greater than the length of the fixing rod, when the power cord is inserted into the fixing groove, the fixing rod slides to the end of the sliding groove, causing the fixing groove and the power hole on the power box to be offset, thereby fixing the power cord.

[0021] The utility model is further configured that one end of the pull rope is fixedly connected to the end of the fixing rod, and the other end of the pull rope is connected to the second outer wall of the bolt.

[0022] By adopting the above technical solution, when the bolt 2 rotates, the pull rope is wrapped around the outer wall of the bolt 2 under the rotation of the bolt 2, thereby pulling the fixing rod inward, so that the fixing rods at both ends simultaneously fix the power cord, reducing the time spent on installing the power cord and making it more convenient to use.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] The utility model is provided with an embedding block, a clamping block and a mounting block. Under the action of the embedding block and the clamping block, the switch device body is not easy to fall off from the reserved switch slot. Under the action of the mounting block, when the switch device body slides into the switch slot, the rubber characteristics of the mounting block increase the friction between the switch device body and the inner wall of the switch slot when the switch device body is installed in the switch slot, so that the switch device body is firmly installed in the switch slot, thereby making the switch device body easier to install and disassemble, and reducing the time consumption of installation and disassembly.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] Embodiment 1

[0035] A time-delay switch for light control, such as Figure 1 - Figure 4 As shown, it includes a switch device body 1.

[0036] Specifically, the switch device body 1 is composed of a power box 101 and a switch key 102. An embedded block 2 is fixedly installed at the end of the switch device body 1. The embedded block 2 is placed in the switch slot reserved in the wall, so that the embedded block 2 is tightly connected with the switch slot, so that the switch device body 1 is installed in the embedded block 2 and is not easy to fall off, so that the switch device body 1 is not easy to be damaged. A card block 3 is slidably installed in the switch device body 1. When the switch device body 1 and the embedded block 2 are installed, the card block 3 is connected with the embedded block 2, so as to limit the switch device body. 1 slides outward, thus causing it to fall off, and a protrusion 4 is fixedly installed on the outer wall of the switch device body 1. When installing and removing the switch device body 1, the switch device body 1 needs to be taken out of the switch slot by hand. However, the surface of the switch device body 1 is smooth, so that when taking it out manually, the hand has no force point, which is more strenuous. Therefore, under the action of the protrusion 4, when taking it out manually, the fingers have a force point on the surface of the switch device body 1, so that it is easy to take out the switch device body 1. A card slot 5 corresponding to the card block 3 is fixedly installed in the embedded block 2. The embedded block 2 is fixedly installed with a card slot 5 corresponding to the card block 3. The switch device body 1 is fixed in the switch slot. When the switch device body 1 is installed toward the embedded block 2, the card block 3 is at the top. When the switch device body 1 is completely embedded in the block 2, the card block 3 is slid downward so that the card block 3 is tightly connected with the card slot 5, thereby limiting the forward and backward movement of the switch device body 1 and reducing the phenomenon of the switch device body 1 falling off. The outer wall of the embedded block 2 is provided with a slot 211 for placing the power cord. The embedded block 2 is fixed in the switch slot so that the wires reserved inside are covered, so that the power supply cannot be connected. The power cord can pass through the slot through the slot 211. 211 extends outward, and a bolt 212 is rotatably installed on the outer wall of the embedded block 2. The embedded block 2 is fixed by the bolt 212, so that the embedded block 2 is always fixed in the switch slot. A mounting block 6 is fixedly installed on the outer wall of the switch device body 1. When the switch device body 1 slides into the switch slot, it slides to a certain extent, so that the mounting block 6 is squeezed with the inner wall of the switch slot. Therefore, when the switch device body 1 completely enters the switch slot, under the action of the mounting block 6, the contact area between the switch device body 1 and the switch slot is increased, and the connection is tighter.

[0037] See also Figure 1 - Figure 4 The embedded block 2 is square in design, which matches the shape of the switch slot and the switch device body 1, so that it fits better during installation and is not easy to shake. The size of the embedded block 2 is consistent with the size of the switch device body 1, and the bolts 212 are two symmetrical designs. When fixing the embedded block 2, the horizontal fixation of the bolts 212 is more stable.

[0038] See also Figure 1 - Figure 4There are two symmetrically mounted blocks 3 on the outer wall of the switch device body 1, so that when the switch device body 1 is connected with the embedded block 2, it is more stable through the horizontal restriction of the block 3, and there are two symmetrically mounted slots 5 on the outer wall of the embedded block 2, and the block 3 is "L"-shaped. When the block 3 is fixed in the slot 5, the "L"-shaped setting of the block 3 makes the switch device body 1 and the embedded block 2 tightly connected, so that the switch device body 1 is not easy to slide back and forth and is not easy to fall off.

[0039] See also Figure 1 - Figure 4 The end edge of the switch device body 1 is designed as a bevel. Through the guidance of the bevel, the switch device body 1 slides into the switch slot more conveniently and smoothly, thereby making the switch device body 1 enter the switch slot more smoothly and reducing the occurrence of jamming.

[0040] See also Figure 1 - Figure 4 The mounting block 6 is of triangular design. When the switch device body 1 slides into the switch slot to a certain length, the mounting block 6 will be squeezed against the inner wall of the switch slot, so that the switch device body 1 and the switch slot are connected more tightly. The mounting block 6 is made of rubber. Since the mounting block 6 is made of rubber, when the mounting block 6 is squeezed against the inner wall of the switch slot, the friction and contact area between the switch device body 1 and the inner wall of the switch slot are increased, so that the switch device body 1 is fixed more firmly.

[0041] Embodiment 2

[0042] See also Figure 5 - Figure 6The difference between the second embodiment and the first embodiment is that on the basis of retaining the first embodiment, a second bolt 7 is rotated and installed on the outer wall of the power box 101. When the wire is inserted into the power box 101, the second bolt 7 is rotated to make the power line more tightly connected to the power box 101, so that the power line can be fixed by rotating the second bolt 7, which saves the time of manually fixing the power lines one by one, making it more convenient to install the power line and reducing the time consumption of the power line installation. A fixing rod 8 is slidably installed on the outer wall of the end of the power box 101. When the power line moves into the power box 101, the second bolt 7 is rotated so that the fixing rod 8 fixes the power line, so that the two power lines are in Under the rotation of bolt 2 7, the fixing is carried out synchronously, and a fixing groove 9 for inserting the power cord is opened on the outer wall of the fixing rod 8. The power cord is inserted into the fixing groove 9, and the fixing rod 8 slides inward under the action of bolt 2 7, so that the power cord is fixed in place, so that the power cord is tightly connected to the power box 101. A pull rope 10 is fixedly installed on the end of the fixing rod 8. Under the action of the pull rope 10, the fixing rod 8 slides inward, so that the fixing rod 8 obtains a sliding force, and a sliding groove 11 for the sliding of the fixing rod 8 is opened in the power box 101. Under the action of the sliding groove 11, the sliding of the fixing rod 8 is smoother, reducing the phenomenon of device jamming, and is more convenient to use.

[0043] See also Figure 5 - Figure 6 There are two fixing rods 8 symmetrically installed on the outer wall of the power box 101, and the ratio of the length of the sliding groove 11 to the length of the fixing rod 8 is 1.5 to 1. When the fixing rod 8 slides inward, since the length of the sliding groove 11 is greater than the length of the fixing rod 8, when the power cord is inserted into the fixing groove 9, the fixing rod 8 slides and slides to the end of the sliding groove 11, thereby causing the fixing groove 9 to be staggered with the power hole on the power box 101, thereby fixing the power cord.

[0044] See also Figure 5 - Figure 6 One end of the pull rope 10 is fixedly connected to the end of the fixing rod 8, and the other end of the pull rope 10 is connected to the outer wall of the bolt 27. When the bolt 27 rotates, the pull rope 10 is wound around the outer wall of the bolt 27 under the rotation of the bolt 27, thereby pulling the fixing rod 8 inward, so that the fixing rods 8 at both ends synchronously fix the power cord, reducing the time spent on installing the power cord and making it more convenient to use.

[0045] The working principle of the utility model is as follows: when installing the switch device body 1, a bolt 212 is used to install the embedding block 2 in the switch groove reserved in the wall, and the wires in the wall are taken out through the groove 211 so that the wires are connected to the switch device body 1. The switch device body 1 is placed in the switch groove. Under the guidance of the inclined surface, the switch device body 1 can enter the switch groove more easily. When the switch device body 1 enters halfway, the installation block 6 is squeezed with the inner wall of the switch groove, so that the switch device body 1 is more firmly installed in the switch groove in the wall. While the switch device body 1 slides into the switch groove, the card block 3 is synchronously moved to the upper side of the card groove 5 in the embedding block 2, and the card block 3 is slid downward, so that the switch device body 1 is tightly connected with the embedding block 2 in the wall switch groove, so that the switch device body 1 is not easy to fall off, thereby making the switch device body 1 easier to install and disassemble, and reducing the time consumed in installation or disassembly.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, technicians in the field of control switches may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
