Description

Technical Field

[0001] This utility model relates to the field of warning light technology, and in particular to an alarm light. Background Technology

[0002] Warning lights generally refer to lighting devices used to emit warning signals. They are widely used as warning signs in a variety of special occasions and are suitable for signal communication and location indication for personnel in municipal management, construction, monitoring, rescue and emergency operations.

[0003] In the prior art, alarm lights are generally composed of a support housing and a detachable cover. The support housing usually contains a circuit board, and the lighting element is installed on top of the circuit board.

[0004] It is worth noting that in the prior art, the connection between the support shell and the cover is usually made detachable by snaps (a ring-shaped fixing band is fixedly connected to the lower side of the cover, and a groove is provided on the upper end of the support shell corresponding to the fixing band) or threads.

[0005] However, in practical applications, whether using snap-fit ​​or threaded connections, a certain amount of operating space is required to achieve a detachable connection between the cover and the supporting housing. (In actual operation, both snap-fit ​​and threaded connections require the operator to apply significant frictional force to change the state of the cover. To apply significant frictional force to the cover, the operator's fingers must be bent, which requires a large operating space for the operator's fingers.) This makes operation difficult, especially for alarm lights used near machine tools in factory areas, where space is limited.

[0006] Therefore, this study argues that it is necessary to develop an alarm light fixture that is easy to disassemble and has low requirements for the surrounding environment. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model proposes an alarm light. This alarm light is easy to operate, has low requirements for the surrounding environment, and effectively solves the problem that existing devices require a large operating space for operator hand movement, while sufficient operating space is generally lacking on-site.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An alarm light includes a cover, a supporting housing detachably connected to the lower side of the cover, and multiple mounting housings fixedly connected to the side end of the supporting housing. The multiple mounting housings are equidistantly arranged around the central axis of the supporting housing. Each mounting housing has an open upper end and a positioning shaft rotatably connected inside each mounting housing. The central axis of the positioning shaft is tangent to the supporting housing. Each mounting housing has a limiting member with a vertical Z-shaped structure inside. The limiting member is rotatably connected to the mounting housing via the positioning shaft. Multiple mating rods are fixedly connected to the side end of the cover, and each mating rod corresponds to one of the multiple mounting housings. Each mating rod has a through hole. When the cover is inserted into the supporting housing, the mating rod is inserted into the mounting housing, and one horizontal segment of the limiting member is inserted into the through hole.

[0010] Preferably, a compression spring I is fixedly connected to the lower end of the limiting member. The compression spring I is located directly below the corresponding mating rod. When one horizontal section of the limiting member is inserted into the corresponding through hole, the two axial ends of the compression spring I abut against the inner wall of the mounting housing and the lower end face of the mating rod, respectively.

[0011] Preferably, a compression spring II is fixedly connected to the lower end of the limiting member. Compression spring I and compression spring II are respectively located on the lower side of the two horizontal sections of the limiting member. When compression spring I and compression spring II are not affected by external force, the angle between the center line of the two horizontal sections of the limiting member and the horizontal plane is zero, and the distance between the limiting member and the inner wall of the side end of the mounting housing is less than the thickness of the mating rod.

[0012] Preferably, the mating rod and the horizontal section of the limiting member near the cover are in the same vertical plane, and a driving rod is movably connected to the upper side of the horizontal section of the limiting member away from the cover.

[0013] Preferably, each of the limiting members has an inclined surface on the side near the cover, and the width of the upper end face of the horizontal section of each limiting member on the side near the cover is smaller than the width of its lower end face.

[0014] Preferably, a contact ring is fixedly connected to the upper ends of the plurality of drive rods, and the plurality of drive rods are slidably connected to the mounting housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a limiting component inside the mounting housing and a mating rod on the side of the cover, with a through hole on the mating rod matching the limiting component. This allows the limiting component to be inserted into the through hole simultaneously with the mating rod, thus fixing the position of the mating rod and ensuring relative stability between the cover and the supporting housing. Furthermore, the Z-shaped structure of the limiting component and its rotational connection to the mounting housing via a positioning shaft allow the horizontal segment of the limiting component to change position during rotation, thereby determining the mating relationship between the limiting component and the mating rod. This design not only achieves stable positioning of the mating rod but also effectively avoids the inconvenience of disassembling the cover within a small size range. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Please see Figure 1 An alarm light, consistent with current technology. This device consists of a cover 1, the bottom of which is detachably connected to a support housing 3.

[0026] Of particular note is that, in practical applications, the support housing 3 often contains a removable circuit board, with an alarm light mounted on top of the circuit board. The control and power supply of the alarm light are both achieved through the circuit board, allowing the alarm light device to be programmed and adjusted as needed to adapt to various alarm scenarios.

[0027] Therefore, the support housing 3 is typically equipped with heat dissipation holes to ensure effective heat dissipation for the circuit board. The cover 1 is equipped with light-transmitting holes to ensure that the flashing of the alarm light is quickly noticed by the operator. These detailed design features fully consider both the performance of the device and the safety of the operator.

[0028] In addition, the lower end of the support housing 3 is usually provided with a threaded hole, into which bolts (not shown in the figure) are inserted to connect with various devices, thereby fixing the alarm light device. This connection method provides a stable mounting base, ensuring the stability of the device during use.

[0029] Please see Figure 2 , Figure 3 The difference between this device and existing devices lies in the fact that multiple mounting housings 4 are securely connected to the side of the support housing 3, and they are equidistantly distributed around the central axis of the support housing 3. This design not only increases the stability and durability of the device, but also makes the device look neater and more orderly.

[0030] Meanwhile, multiple mating rods 5 are fixedly connected to the side end of the cover 1, and each mating rod 5 is provided with a through hole 6.

[0031] Therefore, this device ensures that the number of mating rods 5 and mounting housings 4 are consistent, and that the number of mating rods 5 and mounting housings 4 are consistent and correspond one-to-one. By utilizing the open structure at the upper end of the mounting housing 4, the mating rods 5 can be easily inserted into the corresponding mounting housing 4.

[0032] In addition, such as Figure 4 , Figure 5As shown, the device also has a limiting member 7 with a vertical Z-shaped structure inside each mounting housing 4.

[0033] Therefore, by ensuring that the width and height of the through hole 6 match the horizontal section of the limiting member 7, when the mating rod 5 is inserted into the mounting housing 4, the vertical section of the limiting member 7 can be smoothly inserted into the through hole 6 of the mating rod 5, thereby achieving a stable fixation of the mating rod 5.

[0034] It is worth noting that the device also has a positioning shaft 10 rotatably connected inside each mounting housing 4. The device rotatably connects the limiting member 7 to the mounting housing 4 through the positioning shaft 10. Rotating the limiting member 7 can adjust its projected length on the horizontal plane, thereby changing the position of the horizontal section of the limiting member 7, achieving the technical purpose of the limiting member 7 being dislodged from the through hole 6, thereby removing the position restriction on the mating rod 5 and facilitating the disassembly of the cover 1 and the support housing 3.

[0035] It is worth noting that, in practice, since the projections of the cover 1 and the supporting shell 3 on the horizontal plane are both circular, the projection of the limiting member 7 on the horizontal plane is designed to be arc-shaped to ensure the rationality of the overall shape and structure of the device. Furthermore, the center of this arc coincides with the central axis of the cover 1 and the supporting shell 3. This design not only ensures the aesthetics of the device but also guarantees its balance and stability during use.

[0036] Therefore, in order to ensure that the limiting member 7 can rotate normally and that the rotation direction of the limiting member 7 is suitable for the arrangement of multiple mating rods 5, this device ensures that the central axis of each positioning shaft 10 is tangent to the support housing 3.

[0037] It should be noted that in practice, such as Figure 4 As shown, to ensure that the operator can accurately control the rotation of the limiting member 7 and change the fit between the limiting member 7 and the through hole 6, the constraint fitting rod 5 and the horizontal section of the limiting member 7 near the cover 1 are in the same vertical plane. At this time, the operator can more easily control the horizontal section of the limiting member 7 away from the cover 1, thus achieving the rotation of the limiting member 7.

[0038] It needs to be emphasized that, such as Figure 2 As shown, the projection of a single mating rod 5 on the vertical plane is an inverted L-shaped structure. There is a gap between the single mating rod 5 and the outer end of the cover 1. This design is intended to... Figure 1 The structure of the supporting shell 3 is matched to ensure that the supporting shell 3 can be smoothly fitted onto the outside of the cover 1, while avoiding interference between the matching rod 5 and the supporting shell 3. Thus, the position of the cover 1 is effectively constrained by inserting into the gap between the matching rod 5 and the cover 1.

[0039] In addition, such as Figure 2As shown, the upper end of the mating rod 5 is fixedly connected to the cover 1 through a thin connecting part. In practice, by constraining the material of the mating rod 5 to be an elastic material (such as PE material), the mating rod 5 can be bent. The elastic material of the mating rod 5 (such as PE material) allows it to be bent. This feature further improves the convenience of inserting the support shell 3 into the gap between the cover 1 and the mating rod 5.

[0040] Furthermore, such as Figure 4 , Figure 5 As shown, since the projection of the limiting member 7 on the vertical plane is a Z-shaped structure, and the horizontal section of the limiting member 7 near the cover 1 is inserted into the through hole 6, there is a large gap at the lower end of the mating rod 5 in practice. To make up for this gap, a compression spring I11 is fixedly connected to the lower end of the limiting member 7. The compression spring I11 is located directly below the corresponding mating rod 5, so that the compression spring I11 provides additional upward thrust to the mating rod 5, preventing the mating rod 5 and the cover 1 from moving downward, thereby maintaining a suitable height difference between the cover 1 and the support shell 3.

[0041] It should be noted that the presence of compression spring I11 allows the cover 1 to undergo a small longitudinal displacement relative to the supporting shell 3 in practice. This longitudinal displacement can reduce the damage to the cover 1 when it is subjected to impact. During this process, compression spring I11 ensures the automatic reset function of the cover 1.

[0042] Meanwhile, the presence of compression spring I11 allows the operator to directly press down on the cover 1 and insert the mating rod 5 into the mounting housing 4. When the position of the through hole 6 is lower than the horizontal section of the limiting member 7, the compression spring I11 will automatically assist the cover 1 to move upward, realizing the automatic mating of the limiting member 7 and the through hole 6.

[0043] In addition, such as Figure 4 , Figure 5 As shown, a compression spring II 9 is added below another horizontal section of the limiting member 7 in this device, located on both sides of the positioning shaft 10 along with compression spring I 11. These two springs together provide an upward thrust to both sides of the limiting member 7, ensuring the overall balance of the limiting member 7 and preventing it from tilting to one side, thereby ensuring that the limiting member 7 can be smoothly inserted into the through hole 6 and forming an effective positional constraint on the cover 1.

[0044] Therefore, when the compression springs I11 and II9 are not affected by external forces, the angle between the center lines of the two horizontal segments of the limiting member 7 and the horizontal plane is zero. Furthermore, at this time, the distance between the limiting member 7 and the inner wall of the side end of the mounting housing 4 is less than the thickness of the mating rod 5, thus ensuring that the limiting member 7 can be inserted into the through hole 6 to form a positional constraint on the mating rod 5, preventing the mating rod 5 from spontaneously releasing the mating state between the limiting member 7 and the through hole 6 through movement.

[0045] Furthermore, this device constrains each limiting member 7 to have an inclined surface on the side near the cover 1. That is, the width of the upper end face of the horizontal section of each limiting member 7 near the cover 1 is smaller than the width of its lower end face. This allows the operator to press down on the cover 1 and insert the mating rod 5 into the mounting housing 4. The mating rod 5 presses down on the limiting member 7, and the inclined surface on the limiting member 7 can convert the downward pressing force applied by the mating rod 5 on the limiting member 7 into a horizontal thrust, thereby forcing the limiting member 7 to rotate spontaneously and achieve the engagement between the limiting member 7 and the through hole 6.

[0046] like Figure 4 , Figure 5 As shown, in order to facilitate the operator to control the rotation of the limiting member 7, a drive rod 8 is slidably connected to the upper side of the horizontal section of each limiting member 7 away from the cover 1. By moving the drive rod 8 downward, the balance state of the limiting member 7 can be broken, thereby realizing its rotation.

[0047] Furthermore, the upper ends of multiple drive rods 8 are fixedly connected to a contact ring 2, thereby ensuring that multiple drive rods 8 can move synchronously.

[0048] It is worth noting that, such as Figure 5 As shown, the projection of the drive rod 8 on the horizontal plane is also an arc-shaped structure. A limit hole is opened through its side end, and a limit rod is inserted into the limit hole. This measure uses the mutual cooperation between the limit rod and the limit hole to constrain the displacement trajectory of the drive rod 8 and minimize the frictional resistance encountered by the drive rod 8 during its movement.

[0049] Meanwhile, the projections of the limiting hole and the limiting rod on the horizontal plane are also arc-shaped structures. This design, through the inconsistent structure between the two ends and the middle of the limiting rod, effectively prevents the drive rod 8 from rotating around the limiting rod, thereby ensuring that the operator can drive the drive rod 8 to move vertically downward when pressing the contact ring 2 downward.

[0050] In practical applications of this utility model, when it is necessary to install the cover 1:

[0051] First, the operator moves the cover 1 directly above the support housing 3 to ensure that the support housing 3 and the cover 1 are coaxial.

[0052] Next, the operator rotates the cover 1 and adjusts the position of the mating rod 5 until the mating rod 5 is directly above the mounting housing 4, at which point the rotation of the cover 1 is stopped;

[0053] Subsequently, the operator presses down on the cover 1, thereby causing the mating rod 5 to apply downward pressure to the limiting member 7. At this time, the limiting member 7 rotates clockwise, the contact ring 2 rises, and the compressed spring I11 stores elastic potential energy.

[0054] Finally, the operator releases the cover 1, and the elastic potential energy stored in the compression spring I11 is released, pushing the cover 1 to move upward. During this process, under the action of the frictional resistance between the mating rod 5 and the limiting member 7 and the weight of the limiting member 7 itself, the limiting member 7 rotates counterclockwise. The distance between the horizontal section of the limiting member 7 near the cover 1 and the through hole 6 gradually decreases until the horizontal section of the limiting member 7 is completely inserted into the through hole 6, thus completing the installation of the cover 1.

[0055] In practical applications of this invention, when it is necessary to disassemble the cover 1:

[0056] The operator applies downward pressure to the contact ring 2, and the drive rod 8 then moves the limiting member 7 downward to the opposite side of the cover 1 and rotates counterclockwise. During this process, the compression spring I 11 continuously releases its stored elastic potential energy, pushing the cover 1 to rise continuously until it is completely separated from the supporting shell 3. Subsequently, the compression spring I 11 contacts the horizontal part of the limiting member 7 near the cover 1, and the operator releases the contact ring 2, thus completing the disassembly process of the cover 1.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
