DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] like Figures 1 to 13 As shown, a new type of pure explosion-proof lamp includes: The flameproof body 1 is obtained by processing a metal profile, wherein the metal profile comprises a ring body 11 which is arranged to form an explosion-proof cavity 13. The design of the ring body 11 can provide a compact and stable explosion-proof cavity structure to ensure the safety of the lamp in a dangerous environment, and two convex edges 12 which protrude outwardly relative to the ring body 11. The ring body 11 and the convex edges 12 are integrally formed by a mold; a lighting strip 2 is installed outside the ring body 11 and is located between the two convex edges 12, and is connected to a wiring harness led out from the explosion-proof cavity 13; a transparent glass plate 3 is partially inserted between the two convex edges 12, covers the lighting strip 2 and emits light through the illumination of the lighting strip 2, thereby ensuring the performance of the lighting function; a fixing structure 4 fixes the transparent glass plate 3 relative to the convex edges 12; two sealing structures 5 are provided to seal the two ends of the explosion-proof cavity 13 respectively, and the main structure of the pure flameproof new lamp is obtained by cooperating with the metal profile.

[0022] In the present embodiment, a new type of pure explosion-proof lamp is provided, which can be used as a fire emergency lighting lamp and an evacuation indicator light. The explosion-proof main body 1 is obtained by processing the profile, which realizes a new manufacturing method. Compared with the traditional die-casting structure, the profile processing is convenient, the size controllability is strong, and the structure is stable. The explosion-proof main body 1 shell serves both the fire emergency lighting lamp and the evacuation indicator light, realizing multiple uses of one mold and effectively reducing the production cost.

[0023] The pure flameproof new lamp in this embodiment has a higher flameproof grade and is less restricted by the use environment. Because the design is based on glass material display, the display range will be larger and can be used in different directions.

[0024] The metal profile has a specific cross-sectional shape and size. Specifically in this embodiment, by controlling the processing mold of the metal profile, the ring body 11 that forms the explosion-proof cavity 13 and the integrated specific size processing of the two convex edges 12 can be achieved. The higher integrity can effectively ensure the explosion-proof performance; of course, in order to ensure the assembly requirements of the overall structure, the metal profile needs to be further processed, including but not limited to: drilling holes in the ring body 11 to achieve the penetration of the wiring harness through the hole 14; processing the end of the ring body 11 to obtain a mounting structure corresponding to the blocking structure 5.

[0025] In order to better achieve the installation stability of the transparent glass plate 3, as a preferred embodiment of the above, see Figures 2~5 , the fixed structure 4 comprises: Two limiting sliders 41 are provided, which are fixedly connected to the convex edges 12 respectively, and are limited against the transparent glass plate 3 on both sides in the length direction of the profile, thereby preventing the transparent glass plate 3 from moving in this direction; the fixed frame 42 covers the edges of the transparent glass plate 3 located outside the two convex edges 12, thereby effectively protecting the transparent glass plate 3. In order to better position the transparent glass plate 3 relative to the fixed frame 42, a recessed position for accommodating a local edge of the transparent glass plate 3 can be provided on the fixed frame 42, and the recessed position here can be a continuous groove structure; the fixed frame 42 is fixedly connected to the limiting slider 41.

[0026] By the fixed connection between the limit slider 41 and the flange 12, and the fixed connection between the fixing frame 42 and the limit slider 41, the transparent glass plate 3 is effectively protected and fixed by wrapping around it without damaging it, and the transparent glass plate 3 can maintain a stable use state. Specifically, during the installation process, the limit slider 41 and the flange 12 can be fixedly connected by the connecting member 43, and similarly, the fixing frame 42 and the limit slider 41 are connected by the connecting member 43. In order to achieve the fixing of the connecting member 43, a through hole can be opened above the flange 12, and this operation does not affect the explosion-proof performance of the lamp.

[0027] As a preferred embodiment of the above, Figure 6 and 7 As shown, the metal profile is outside the ring body 11 and between the two convex edges 12, and is integrally formed along the length direction: The groove 15 provides an installation space for the lighting strip 2; two limiting surfaces 16 are symmetrically arranged on both sides of the groove 15, and the limiting surfaces 16 are abutted against the end surface of the transparent glass plate 3 for limiting; the transparent glass plate 3 closes the open end of the groove 15.

[0028] In this way, the lighting strip 2 obtains a stable installation space, avoids the influence of the external environment, and ensures its service life; the groove 15 and the limiting surface 16 in this preferred embodiment can be formed in an integrated manner during the metal profile forming process without adding additional costs.

[0029] In order to further improve the installation stability of the transparent glass plate 3, as a preferred embodiment of the above, see also Figure 7 The metal profile is outside the ring body 11 and located between the two convex edges 12, and is also integrally formed along the length direction: two step structures 17 symmetrically arranged on both sides of the groove 15, the step structures 17 connect the convex edge 12 and the limiting surface 16 on the same side; the transparent glass plate 3 is arranged between the two step structures 17, spaced from the convex edge 12, and the gap between them is filled with glue.

[0030] By filling with glue, the transparent glass plate 3 is fixed more stably, and a certain buffering effect can be achieved on both sides of the transparent glass plate 3, which reduces the interaction force between the transparent glass plate 3 and the flameproof body 1 in the event of vibration or collision, thereby ensuring the safe use of the transparent glass plate 3.

[0031] In the case of filling with glue, as preferably, see Figure 2 The pure flameproof new lamp also includes a ring-shaped light shielding plate 6; the light shielding plate 6 is sleeved on the outer periphery of the transparent glass plate 3, clamped between the limit slider 41 and the fixed frame 42, and shields the gap between the transparent glass plate 3 and the convex edge 12. The light shielding plate 6 can ensure the aesthetics after the glue is filled, and can block the illumination light from being emitted from the glue solidification structure, and more concentratedly project from the transparent glass plate 3.

[0032] As a preferred embodiment of the above, see Figure 2 The blocking structure 5 includes a flameproof side cover 51 and a wire nut 52; the flameproof side cover 51 is connected to the flameproof body 1 by threads and is provided with a through hole; the wire nut 52 is connected to the through hole of the flameproof side cover 51 by threads for the wiring harness to pass through.

[0033] In this preferred embodiment, the flameproof side cover 51 and the flameproof main body 1 together form a structural combination for realizing the flameproof function. The use of the crimping nut 52 can ensure the convenient installation of the wire harness and the sealing of the position where the wire harness penetrates. During use, the crimping nut 52 can be matched with the wire harness accordingly to ensure the adaptability and fit of the position where the wire harness penetrates.

[0034] In order to improve the installation convenience of pure flameproof new lamps, see Figure 8 The metal profile also includes a guide belt 18 protruding outward relative to the ring body 11, and the guide belt 18, the ring body 11 and the flange 12 are integrally formed by a mold; the pure flameproof new lamp also includes at least one mounting slide 8, which is arranged to slide linearly along the guide belt 18, and a fixed position for installing the connecting piece 43 is opened on the mounting slide 8.

[0035] During the installation of the pure flameproof new lamp, the installation slider 8 can be fixed first. At this time, the installation slider 8 is separated from the flameproof main body 1, which is convenient for installation. The connecting member 43 referred to here includes but is not limited to bolts, screws and other structures. When more than one installation slider 8 is provided, it is necessary to ensure that each installation slider 8 is installed in the same straight line. After the installation slider 8 is fixed, the flameproof main body 1 can be installed relative to the installation slider 8 by sliding. The installation here only needs to connect the guide belt 18 and the installation slider 8 and perform a linear sliding action.

[0036] In this preferred embodiment, as a specific implementation method, see also Figure 8 The guide belt 18 can adopt a T-shaped cross-section, and the two ends of one side of the T form a concave guide groove between the outer surface of the ring body 11, and two guide edges inserted into the guide groove are correspondingly provided on the mounting slider 8. The other parts of the mounting slider 8 except the guide edges can be appropriately spaced apart from the ring body 11 to avoid interference between the connecting piece 43 and the ring body 11.

[0037] In order to ensure lighting in emergency situations, as a preferred embodiment of the above, Fig.14 and 15 As shown, the new pure explosion-proof lamp also includes at least one emergency lamp holder module; the emergency lamp holder module includes an emergency light 91 and a cable lead-in device 92, the emergency light 91 is directly or indirectly connected to the explosion-proof main body 1, and the cable lead-in device 92 is fixedly connected to the explosion-proof main body 1; the cable lead-in device 92 is led out from the explosion-proof cavity 13, and the wiring harness connected to the emergency light 91 is passed through and fixed.

[0038] In this preferred embodiment, the emergency light 91 can be installed by fixing it through the installation slider 8 in the above embodiment. This method is an indirect installation method relative to the explosion-proof main body 1. This method will reduce the impact on the explosion-proof main body 1. After the connection relationship between the emergency light 91 and the installation slider 8 is established, the connection relationship between the installation slider 8 and the explosion-proof main body 1 can be established; as another installation method of the emergency light 91, a threaded hole 19 can also be directly opened on the explosion-proof main body 1, and the connection relationship between the emergency light 91 and the explosion-proof main body 1 is established through a connecting piece; the above two methods are both within the protection scope of the present invention.

[0039] As for the cable lead-in device 92, since the wiring harness needs to be led out from the explosion-proof cavity 13, it can be installed directly based on the hole for leading out the wiring harness. Specifically, the hole can be directly opened as a threaded hole 19, and a threaded rod structure is provided on the cable lead-in device 92, thereby realizing the rapid installation of the cable lead-in device 92 relative to the explosion-proof main body 1.

[0040] In order to ensure the intuitive evaluability of the status of the new pure flameproof lamp and improve the use effect of the product, as a preferred embodiment of the above, Figures 9 to 13 As shown, the new pure flameproof lamp also includes a test module 7 and a battery, wherein the battery can be arranged in the explosion-proof cavity 13, or can be protected by an additional structure outside the ring body 11; The test module 7 includes a test light strip 71 having a plurality of lamp beads. The test light strip 71 is installed between the two convex edges 12 and connected to the wiring harness led out from the explosion-proof cavity 13. In the length direction of the profile, the test light strip 71 and the lighting light strip 2 are arranged in parallel with each other at intervals. Fig.10 , showing the installation position of the test light strip 71, see Fig.11 , showing the specific form of parallel setting.

[0041] The fixed structure 4 covers the test light strip 71, and a light-transmitting hole is opened corresponding to each lamp bead one by one, so that the light emitted by each lamp bead can be transmitted; taking the specific structural form of the fixed structure 4 including the limit slider 41 and the fixed frame 42 in the above embodiment as an example, Fig.12 and 13 As shown, an edge structure 42a covering the test light strip 71 can be formed by extending the end of the fixed frame 42, and the edge structure 42a can also be connected to the limit slider 41. This method can reduce the number of structural components; the test module 7 also includes a control unit, which is installed in the explosion-proof cavity 13, and the control end 72 of the control unit passes through the ring body 11 and protrudes from the surface of the ring body 11; the control unit is respectively connected to the lighting light strip 2, the test light strip 71, the battery and the main power supply, and performs test control of the pure explosion-proof new lamp according to the user's operation on the control end 72.

[0042] In this preferred embodiment, the control unit can perform the test process under the operation of the control terminal 72 through a pre-set program. This integrated test design makes the maintenance and repair of the lamp more efficient and reduces the complexity of manual operation. Specifically, the control unit can be based on a microcontroller and implement multi-functional control through programming, such as switching lighting mode and test mode. In order to distinguish different test results, different lamp beads can be assigned different numbers, or lamp beads of different distinguishable colors can be used. The control terminal 72 in this preferred embodiment can specifically refer to a press or slide switch structure.

[0043] In normal use of the pure flameproof new lamp, after the main power supply is turned on, the lighting strip 2 can be controlled to emit light normally, and at least one lamp bead on the test strip 71 can emit light normally. Within the set time period, the test is performed to see whether the emitting lamp bead is extinguished, and whether the battery completes the set charging requirement after extinguishing, so as to judge the performance of the battery. In this test, the main power supply is AC22V power supply, and the test strip 71 includes red, green and yellow lamp beads, and the red lamp bead is used as the above-mentioned emitting lamp bead. The set time period is 24h, and the charging requirement is that the charging current is less than 20m Taking A as an example, after the main power supply is turned on, the red light bead must be off within 24 hours, and the battery charging current must be less than 20mA. This process is used to test the battery. The switching test between the main power supply and the battery power supply can also be performed, such as the main power supply for 1min, the emergency power supply for 20s, the main power supply for 1min... Cycle switching, specifically 50 times as an example, this process is used to test the switching between the main power supply and the battery. It can also be completely switched to battery power supply to determine whether the set discharge time can be met. Taking a 600mA battery as an example, the discharge time must exceed 2h.

[0044] In addition to the above tests, as a preferred method, the test control of the pure flameproof new lamp is performed according to the user's operation on the control terminal 72, including at least one of the following methods: The first method is: the main power supply is turned on, and the continuous operation of the control terminal 72 is less than the first time, the control unit controls the main power supply to be cut off, and the test light strip 71 switches from at least partially emitting light to completely extinguishing, entering the emergency state powered by the battery, and releasing the operation of the control terminal 72, and returning to the main power supply state; in the implementation process, the first time can be specifically set to 3s, of course, other times are also sufficient, but the test efficiency needs to be comprehensively considered; The second type: turn on the main power supply, the continuous operation time of the control terminal 72 is greater than or equal to the first time and less than the second time, the control unit controls one of the lamp beads of the test lamp strip 71 to flash at the first set frequency, and enters the emergency state powered by the battery, and the emergency state is automatically released after the set time and returns to the main power supply state; the flashing time can be specifically set to between 30 and 40 seconds, and the first set frequency can be 1Hz. Of course, the above value is only a specific example and is not used as a limitation on the protection range; based on the specific method of setting the first time to 3s, the second time of 5s can be used in this test; for the flashing lamp beads, lamp beads with specific numbers or specific colors can be specifically selected. In this embodiment, green can be specifically used as an example. This test process can be used as a monthly inspection test for pure flameproof new lamps; The third type: turn on the main power supply, the continuous operation time of the control terminal 72 is greater than or equal to the second time and less than the third time, the control unit controls one of the lamp beads of the test light strip 71 to flash at the second set frequency, and enter the battery-powered emergency state, the emergency state is exited when the control terminal 72 is operated next time, and returns to the main power supply state. In this test, the same lamp beads as in the second method can be used for flashing, or other lamp beads can be replaced for flashing, and the third time can be set to 7s corresponding to 3s and 5s in the above test. Of course, for this time, it is only necessary to meet the first time, the second time and the third time to increase in sequence, and the specific value can be selected as needed; in order to distinguish the test process, the flashing frequency needs to be set differently. In this test, by appropriately extending the timing of the next execution of the control terminal 72 operation, this test can be used to test whether the discharge time of the battery meets the use requirements. For example, if the pure flameproof new lamp is powered off before the time is reached after the next execution of the control terminal 72 operation, it indicates that the battery discharge time is insufficient. This process can be used as an annual inspection test for pure flameproof new lamps.

[0045] In addition to the above tests, the control terminal 72 and the test light strip 71 can also realize the following functions. For example, in an emergency state, if the operation time of the control terminal 72 is greater than or equal to the third time, the emergency state output is turned off; or, in the main power supply state, if the battery is open or short-circuited, the set lamp beads in the test light strip 71 can be set to flash to alarm; or, in the main power supply state, in the above-mentioned monthly inspection test or annual inspection test, when the light source is open or short-circuited, the set lamp beads in the test light strip 71 can be set to flash to alarm.

[0046] As an application method of a new type of pure explosion-proof lamp, it can be specifically used as a fire emergency lighting or an evacuation indicator light.
