Technical Field

[0001] The utility model relates to the technical field of explosion-proof lamps, in particular to a protective structure of an explosion-proof alarm lamp. Background Art

[0002] Explosion-proof alarm lights are widely used as warning signs in various special places. They are also suitable for signal communication and direction indication by municipal administration, construction operations, monitoring, rescue, and emergency workers.

[0003] After searching, Chinese Patent No. CN206890439U was found. This utility model discloses an explosion-proof alarm light protective cover, comprising a first base plate and a second base plate, the first base plate and the second base plate being arranged parallel to each other, the first base plate being located below the second base plate, the first base plate and the second base plate having the same specifications, both of which are provided with positioning holes, the first base plate and the second base plate being connected by a first damping plate and a second damping plate, a mounting seat being provided on the top of the second base plate, the top of the mounting seat being connected to a lower shell, the top of the lower shell being provided with an upper shell, the top of the upper shell being arc-shaped, lamp holders being provided inside the lower shell and the upper shell, the lamp holders being provided with explosion-proof alarm lights, and heat dissipation holes being evenly provided on the lower shell and the upper shell. This utility model provides an explosion-proof alarm light protective cover with a novel structure, easy use, good shock absorption effect, and improved heat dissipation effect.

[0004] The above technology improves the heat dissipation of the alarm by evenly opening heat dissipation holes on the upper shell and the lower shell, and a buffer device is set on the lower side. However, the above technology has certain shortcomings. First, the alarm light is usually used as a warning in some rescue work and construction sites. However, although the heat dissipation holes on the alarm light improve the heat dissipation of the device, the safety of the device is reduced. The heat dissipation holes will first make the alarm light more fragile. Secondly, in some rescue or dangerous scenes, a large amount of dust will enter the alarm light through the heat dissipation holes, which can easily cause damage to the components of the device. Utility Model Content

[0005] The purpose of the utility model is to provide a protective structure for an explosion-proof alarm lamp, which can solve the problem of low safety of the above-mentioned device.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a protective structure for an explosion-proof alarm light, comprising: a base and a first protective cover, the base having mounting slots near both sides, two mounting members fixedly installed on the bottom of the outer surface of the first protective cover, slots being provided on the opposite sides of the two mounting members, a cavity being provided inside the base, two support blocks being symmetrically installed on the upper surface of the cavity, one end of the outer surface of the two support blocks being fixedly connected to a spring 1, and the other end of the two spring 1s being fixedly connected to a fixing head.

[0007] As a preferred embodiment, a small motor is fixedly installed near one side of the cavity, and the output end of the small motor is fixedly connected to a threaded rod, and a slider is rotatably installed on the outer surface of the threaded rod, and two connecting rods are rotatably connected to the upper symmetrical position of the outer surface of the slider, and the other ends of the two connecting rods are rotatably connected to rectangular blocks, and one end of the outer surface of the two rectangular blocks is fixedly installed with a telescopic rod, and the other ends of the two telescopic rods are fixedly installed on one side of the fixed head, and the two telescopic rods are slidably arranged inside the support block.

[0008] The technical effect of adopting the above further solution is: when an emergency occurs and the alarm light device needs to be used, it is only necessary to start the small motor. The small motor will pull the fixed head connected by the telescopic rod backward by controlling the movement of the slider, thereby disengaging the fixed head from the slot, thereby releasing the first protective cover.

[0009] As a preferred embodiment, guide rails are slidably provided on the upper sides of the two rectangular blocks, and the guide rails are fixedly mounted on the upper surface of the cavity.

[0010] The technical effect of adopting the above further solution is: when the slider moves on the threaded rod, the rectangular blocks on both sides are pulled to move by the connecting rod. Therefore, through the limitation of the guide rail, the rectangular blocks can only move in the horizontal reverse direction, so that the fixed head can be pulled out smoothly.

[0011] As a preferred embodiment, springs 2 are fixedly connected to the lower surface of the cavity near both sides, and the other ends of the two springs 2 are fixedly connected to push plates.

[0012] The technical effect of adopting the above-mentioned further solution is: when the first protective cover is installed into the base, the mounting part will press the push plate downward, thereby accumulating elastic potential energy for the spring 2. When the mounting part is released, the spring 2 will instantly release the elastic potential energy, so that the first protective cover can be quickly pushed out of the base through the push plate.

[0013] As a preferred embodiment, an alarm light is fixedly mounted on the upper surface of the base near the center, and a second protective cover is fixedly mounted on the outer surface of the alarm light.

[0014] The technical effect of adopting the above-mentioned further scheme is: the first protective cover is used for daily protection to prevent dust from entering the alarm light and to prevent the alarm light from being maliciously damaged. When it is needed, the protection of the first protective cover is instantly released so that the sound and light released by the alarm light can be seen. At this time, the second protective cover can play a secondary protection role for the alarm light to prevent the alarm light from being damaged by falling rocks.

[0015] As a preferred embodiment, four fixing seats are fixedly installed on the outer surface of the base near the bottom.

[0016] The technical effect of adopting the above further solution is that the above device is usually installed horizontally on the wall, so the device can be easily installed by providing a fixing base.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are:

[0018] 1. The utility model, when not in use, can effectively prevent the alarm light from being covered by dust when no emergency occurs by installing the first protective cover on the outside of the alarm light and fixing it with a fixing head, and at the same time avoids human damage.

[0019] 2. When the utility model is in use, when it is needed, it is only necessary to start the small motor to release the fixation of the first protective cover through the slider, and the second spring can quickly pop out the first protective cover so that it can be used normally. At this time, the second protective cover can provide secondary protection for the alarm light to avoid damage to the alarm light due to falling rocks. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1 - Figure 5 The utility model provides a technical solution: a protective structure of an explosion-proof alarm lamp: comprising: a base 101 and a first protective cover 102, the base 101 is provided with mounting slots 108 near both sides, the bottom of the outer surface of the first protective cover 102 is fixedly installed with two mounting members 103, and the two mounting members 103 are provided with slots 104 on the opposite sides. A cavity 201 is provided inside the base 101, and two support blocks 208 are symmetrically installed on the upper surface of the cavity 201, and one end of the outer surface of the two support blocks 208 is fixedly connected to a spring 209, and the other end of the two springs 209 is fixedly connected to a fixing head 210.

[0029] like Figure 1 - Figure 5 As shown, a small motor 202 is fixedly installed near one side of the cavity 201, and a threaded rod 203 is fixedly connected to the output end of the small motor 202. A slider 204 is rotatably installed on the outer surface of the threaded rod 203, and two connecting rods 205 are rotatably connected to the upper symmetrical position of the outer surface of the slider 204. The other ends of the two connecting rods 205 are rotatably connected to rectangular blocks 206. One end of the outer surface of the two rectangular blocks 206 is fixedly installed with a telescopic rod 207. The other ends of the two telescopic rods 207 are fixedly installed on one side of the fixed head 210. The two telescopic rods 207 are slidably set inside the support block 208. When an emergency occurs and the alarm light 106 device needs to be used, it is only necessary to start the small motor 202. The small motor 202 will pull the fixed head 210 connected by the telescopic rod 207 backward by controlling the movement of the slider 204, thereby disengaging the fixed head 210 from the slot 104, thereby releasing the first protective cover 102.

[0030] like Figure 1 - Figure 5 As shown, the upper sides of the two rectangular blocks 206 are slidingly provided with guide rails 211, and the guide rails 211 are fixedly installed on the upper surface of the cavity 201. When the slider 204 moves on the threaded rod 203, the rectangular blocks 206 on both sides are pulled to move by the connecting rod 205. Therefore, through the restriction of the guide rails 211, the rectangular blocks 206 can only move in the horizontal direction, so that the fixed head 210 can be pulled out smoothly.

[0031] like Figure 1 - Figure 5 As shown, spring 2 302 is fixedly connected to the lower surface of the cavity 201 near both sides, and the other ends of the two springs 2 302 are fixedly connected to the push plates 301. When the first protective cover 102 is installed into the base 101, the mounting member 103 will press the push plates 301 downward, thereby accumulating elastic potential energy for the spring 2 302. When the mounting member 103 is released, the spring 2 302 will instantly release the elastic potential energy, so that the first protective cover 102 can be quickly pushed out of the base 101 through the push plates 301.

[0032] like Figure 1 - Figure 5 As shown, an alarm light 106 is fixedly installed near the center on the upper surface of the base 101, and a second protective cover 107 is fixedly installed on the outer surface of the alarm light 106. The first protective cover 102 is used for daily protection to prevent dust from entering the inside of the alarm light 106 and to prevent the alarm light 106 from being maliciously damaged. When it is needed, the protection of the first protective cover 102 is instantly released so that the sound and light released by the alarm light 106 can be seen. At this time, the second protective cover 107 can play a secondary protection role for the alarm light 106 to prevent the alarm light 106 from being damaged by falling rocks.

[0033] like Figure 1 - Figure 5 As shown, four fixing seats 105 are fixedly installed on the outer surface of the base 101 near the bottom. The above device is usually installed horizontally on a wall, so the device can be easily installed by providing the fixing seats 105.

[0034] Working principle: When it is needed, the small motor 202 is started, and the output end of the small motor 202 controls the threaded rod 203 to rotate inside the cavity 201, so that the slider 204 set on the outer surface of the threaded rod 203 is moved. Since the connecting rod 205 is rotatably connected between the slider 204 and the rectangular block 206, the rectangular block 206 will move with the movement of the slider 204. Since the two sliders 204 are both slidably set on the guide rail 211 inside the cavity 201, the two rectangular blocks 206 can only slide in the direction of the guide rail 211. When the two rectangular blocks 206 slide toward each other, they will pull the telescopic rod 207 on one side to move synchronously. When the first protective cover 102 is detached, the second protective cover 107 on the outer surface of the alarm light 106 will provide secondary protection for the alarm light 106 to avoid damage caused by falling rocks.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
