Description

Technical Field

[0001] This invention relates to the field of broadcasting equipment technology, and in particular to a user-friendly handheld emergency broadcasting device. Background Technology

[0002] Handheld emergency broadcasters are broadcasting devices mainly used in rescue operations. Because they can be held by the operator, they are extremely convenient and suitable for calling for help at any time during a rescue.

[0003] A search of existing technology CN116506051A reveals a handheld emergency broadcasting system, including a belt and a broadcaster; it can be used for handheld broadcasting rescue or mounted on a belt for broadcasting rescue, and when mounted on a belt, it can automatically broadcast rescue information in a circumferential manner, saving the operator's physical strength and enabling the operator to continue rescue for a longer period of time. During the automatic reset process, it automatically performs circumferential life detection, with rescue broadcasting and life detection alternating, thereby improving the accuracy of life detection and increasing the success rate of rescue.

[0004] While existing handheld emergency broadcasters can be mounted on a belt for automatic circumferential emergency broadcasting, they are limited to a circular broadcast pattern and cannot be adjusted for height or elevation. This significantly restricts the broadcast's reach, making it unsuitable for wider use in emergencies. Furthermore, other traditional handheld emergency broadcasting devices require prolonged arm movements to adjust the broadcast range, which is time-consuming and laborious.

[0005] Therefore, the present invention proposes an easy-to-use handheld emergency broadcasting device to solve the above problems. Summary of the Invention

[0006] Based on the technical problems existing in the background art, the present invention proposes a handheld emergency broadcasting device that is easy to use.

[0007] This invention proposes a user-friendly handheld emergency broadcasting device, comprising a handheld handle and an emergency broadcasting body. The handheld handle has a movable groove, in which a support rod is movably mounted via a height adjustment mechanism. The top of the support rod extends movably above the movable groove and is fixedly connected to a first support block. A second support block is movably mounted on the first support block via a circumferential orientation adjustment mechanism. The second support block has a transition groove, in which a transition block is rotatably mounted via an elevation adjustment mechanism, and the emergency broadcasting body is fixedly mounted on the top of the transition block.

[0008] The elevation adjustment mechanism includes a rotating shaft rotatably mounted in a transition groove, and a transition block fixedly sleeved on the rotating shaft; the bottom of the transition block has an inverted rounded structure, and a second toothed groove is formed on the inverted rounded surface of the bottom of the transition block; a toothed block is movably mounted in the transition groove located below the transition block, and a plurality of second gear protrusions are fixedly connected to the top of the toothed block, and the top of the toothed block engages with the second toothed groove at the bottom of the transition block through the second gear protrusions; a motor cavity is also provided on the second support block located below the transition groove, and a second stepper motor is fixedly mounted in the motor cavity. The output end of the second stepper motor rotatably passes through the transition groove and is fixedly sleeved with a second gear. A second rack is provided on the front side of the toothed block, and the second gear engages with the second rack.

[0009] The circumferential orientation adjustment mechanism includes a mounting cavity on the first support block, a rotating support column is rotatably mounted in the mounting cavity, and the top end of the rotating support column rotatably extends through to the top of the first support block and is fixedly connected to the bottom of the second support block; a first gear is fixedly sleeved at the bottom end of the rotating support column, an electric telescopic rod is fixedly mounted on the left inner wall of the mounting cavity, and a first rack is fixedly connected to the output end of the electric telescopic rod, and the first gear and the first rack are engaged in transmission.

[0010] In this example, the height adjustment mechanism includes a threaded column rotatably mounted in a movable slot via a bearing seat. A second bevel gear is fixedly connected to the bottom end of the threaded column via a connecting shaft. A first bevel gear meshes with the right side of the second bevel gear. A first stepper motor is fixedly mounted on the bottom inner wall of the movable slot, and the first bevel gear is fixedly sleeved on the output end of the first stepper motor. A threaded connection groove is provided at the bottom of the support rod, and the support rod is threadedly connected to the threaded column via the threaded connection groove.

[0011] In this example, vertical sliders are fixedly installed on both sides of the bottom of the support rod, and vertical grooves are provided on both sides of the inner wall of the movable groove, and the vertical sliders are slidably installed in the vertical grooves along the vertical direction.

[0012] In this example, the circumferential orientation adjustment mechanism further includes an annular support groove located on the top of the first support block, and the annular support groove is arranged in a ring around the rotating support column; multiple supports are rolled on the bottom of the second support block, and ball bearings are rolled on the bottom of the multiple supports, and the bottom sides of the multiple ball bearings are rolled and supported in the annular support groove along the annular trajectory.

[0013] In this example, a bearing is fixedly installed on the top inner wall of the mounting cavity, and the rotating support is rotatably mounted on the bearing.

[0014] In this example, multiple second gear protrusions are arranged at equal intervals on the top of the gear block.

[0015] In this example, both ends of the bottom of the toothed block are fixedly provided with transverse sliders, and both sides of the inner wall of the bottom of the transition groove are provided with transverse sliding grooves, and the transverse sliders are slidably installed in the transverse sliding grooves in the horizontal direction.

[0016] In this example, the outer side of the hand handle is also provided with anti-slip texture, and a controller is also provided on one side of the hand handle. The controller is electrically connected to the emergency broadcast body, the electric telescopic rod, the first stepper motor, and the second stepper motor.

[0017] The beneficial effects of this invention are:

[0018] 1. In the use of emergency broadcasting, this invention sets up a circumferential orientation adjustment mechanism. By extending and retracting the output end of the electric telescopic rod, the first rack moves left and right. When the first rack moves, it meshes with the first gear, which can drive the rotating support to rotate in both directions. When the rotating support rotates, it will drive the second support block, the adapter block, and the emergency broadcasting body to rotate in both directions along the circumferential orientation, so that the emergency broadcasting body can broadcast emergency information along the circumferential orientation.

[0019] 2. In this invention, by setting an elevation angle adjustment mechanism, the elevation angle of the emergency broadcast body can also be swung and adjusted; and the elevation angle adjustment of the emergency broadcast body swinging forward and backward can be coordinated with the adjustment of the emergency broadcast body along the circumferential direction at the same time. This not only enables the emergency broadcast body to broadcast along the circular circumferential direction, but also allows the elevation angle of the emergency broadcast body to be adjusted, which helps to ensure a wider range of transmission during the emergency broadcast process.

[0020] In this invention, by setting a height adjustment mechanism, the height of the emergency broadcast body can also be adjusted, so that the emergency broadcast body can broadcast emergency information during the raising and lowering process, thereby further improving the broadcast range of the emergency broadcast body;

[0021] In summary, this invention allows for the emergency broadcasting unit to rotate in both directions around its circumference, swing in both directions at different elevation angles, and be used for emergency broadcasting during lifting and lowering, all simply by holding the handle. This expands the overall range of emergency broadcasting, reduces limitations in its use, and eliminates the need to hold the device in one position on the handle, avoiding the previous requirement of manually swinging the arm to change the broadcast range. This reduces the difficulty of emergency broadcasting, improves the overall effectiveness, and, due to its simple structure, greatly facilitates use and is suitable for widespread adoption.

[0029] Example

[0030] refer to Figure 1-5 This embodiment proposes a user-friendly handheld emergency broadcasting device, including a handheld handle 1 and an emergency broadcasting body 6. The handheld handle 1 is provided with a movable groove 101, and a support rod 2 is movably installed in the movable groove 101 through a height adjustment mechanism. The top end of the support rod 2 extends movably above the movable groove 101 and is fixedly connected to a first support block 3. A second support block 4 is movably installed on the first support block 3 through a circumferential orientation adjustment mechanism. The second support block 4 is provided with a transition groove 401, and a transition block 5 is rotatably installed in the transition groove 401 through an elevation adjustment mechanism. The emergency broadcasting body 6 is fixedly installed on the top of the transition block 5.

[0031] The elevation adjustment mechanism includes a rotating shaft 502 rotatably mounted in a transition groove 401, and a transition block 5 fixedly sleeved on the rotating shaft 502; the bottom of the transition block 5 has an inverted round structure, and a second tooth groove 501 is provided on the inverted round surface of the bottom of the transition block 5; a tooth block 8 is movably mounted in the transition groove 401 located below the transition block 5, and a plurality of second gear protrusions 802 are fixedly connected to the top of the tooth block 8, and the top of the tooth block 8 is engaged with the second tooth groove 501 at the bottom of the transition block 5 through the second gear protrusions 802; a motor cavity 402 is also provided on the second support block 4 located below the transition groove 401, and a second stepper motor 7 is fixedly mounted in the motor cavity 402. The output end of the second stepper motor 7 rotatably passes through the transition groove 401 and is fixedly sleeved with a second gear 9. A second rack 801 is provided on the front side of the tooth block 8, and the second gear 9 is engaged with the second rack 801.

[0032] The circumferential orientation adjustment mechanism includes a mounting cavity 301 on the first support block 3, a rotating support column 13 rotatably mounted in the mounting cavity 301, and the top end of the rotating support column 13 rotatably passes through to the top of the first support block 3 and is fixedly connected to the bottom of the second support block 4; a first gear 12 is fixedly sleeved at the bottom end of the rotating support column 13; an electric telescopic rod 10 is fixedly mounted on the left inner wall of the mounting cavity 301; a first rack 11 is fixedly connected to the output end of the electric telescopic rod 10; and the first gear 12 and the first rack 11 are engaged in transmission.

[0033] The height adjustment mechanism includes a threaded column 22 rotatably mounted in the movable slot 101 via a bearing seat 21. The bottom end of the threaded column 22 is fixedly connected to a second bevel gear 19 via a connecting shaft 20. A first bevel gear 18 meshes with the right side of the second bevel gear 19. A first stepper motor 17 is fixedly mounted on the bottom inner wall of the movable slot 101, and the first bevel gear 18 is fixedly sleeved on the output end of the first stepper motor 17. The bottom of the support rod 2 is provided with a threaded connection groove 201, and the support rod 2 is threadedly connected to the threaded column 22 via the threaded connection groove 201.

[0034] In this example, vertical sliders 23 are fixedly installed on both sides of the bottom of the support rod 2, and vertical grooves are provided on both sides of the inner wall of the movable groove 101. The vertical sliders 23 are slidably installed in the vertical grooves along the vertical direction.

[0035] In this example, the circumferential orientation adjustment mechanism also includes an annular support groove 162 located on the top of the first support block 3, and the annular support groove 162 is arranged in a ring around the rotating support column 13; multiple supports 161 are rolled on the bottom of the second support block 4, and ball bearings 16 are rolled on the bottom of each of the multiple supports 161, and the bottom sides of the multiple ball bearings 16 are rolled and supported in the annular support groove 162 along an annular trajectory; a bearing 14 is fixedly installed on the top inner wall of the mounting cavity 301, and the rotating support column 13 is rotatably mounted on the bearing 14.

[0036] In this example, multiple second gear protrusions 802 are arranged at equal intervals on the top of the gear block 8; both ends of the bottom of the gear block 8 are fixedly provided with transverse sliders 803, and both sides of the bottom inner wall of the transition groove 401 are provided with transverse sliding grooves, and the transverse sliders 803 are slidably installed in the transverse sliding grooves in the horizontal direction.

[0037] The outer side of the hand handle 1 is also provided with anti-slip texture, and a controller 24 is also provided on one side of the hand handle 1. The controller 15 is electrically connected to the emergency broadcast body 6, the electric telescopic pole 10, the first stepper motor 17, and the second stepper motor 7 respectively.

[0038] like Figure 1-5 The diagram illustrates a user-friendly handheld emergency broadcast device. In emergency situations, users can hold the handle 1 and broadcast emergency information via the emergency broadcast body 6. During emergency broadcasting, the extension and retraction of the output end of the electric telescopic rod 10 in the circumferential adjustment mechanism drives the first rack 11 to move left and right. When the first rack 11 moves, it meshes with the first gear 12, driving the rotating support 13 to rotate forward and backward. The rotation of the rotating support 13 drives the second support block 4, the adapter block 5, and the emergency broadcast body 6 to rotate in a circumferential direction, thus enabling the emergency broadcast body 6 to broadcast emergency information in a circumferential direction. Simultaneously, the second stepper motor 7 in the elevation adjustment mechanism drives the second gear 9 to rotate forward and backward. When the second gear 9 rotates, it meshes with the second rack 801 on the gear block 8, causing the gear block 8 to move back and forth. The movement of the gear block 8 also... The second gear protrusion meshes with the second tooth groove 501 on the rounded surface of the bottom of the adapter block 5, thereby enabling the adapter block 5 to swing forward and backward based on the rotating shaft 502 as the center. The adapter block 5, in turn, drives the emergency broadcast body 6 to swing forward and backward, thus also allowing for the adjustment of the elevation angle of the emergency broadcast body 6. Furthermore, the adjustment of the elevation angle of the emergency broadcast body 6 in both forward and backward swings can be coordinated with the adjustment of the emergency broadcast body 6 along the circumferential direction. This not only enables the emergency broadcast body 6 to broadcast along the circumferential direction, but also allows for the adjustment of the elevation angle of the emergency broadcast body 6, which helps to ensure a wider transmission range during emergency broadcasting and reduces limitations in use, making it particularly suitable for broadcasting in emergency situations.

[0039] Furthermore, during broadcasting, the first stepper motor 17 in the height adjustment mechanism can drive the first bevel gear 18 to rotate in both directions. When the first bevel gear 18 rotates, it also drives the connecting shaft 20 and the threaded column 22 to rotate in both directions through the second bevel gear 19. This allows the support rod 2 to perform upward or downward threaded transmission on the threaded column 22 through the threaded connecting groove 201. When the support rod 2 moves up and down, the height of the emergency broadcast body 6 can also be adjusted. This allows the emergency broadcast body 6 to broadcast emergency messages during the lifting and lowering process, which helps to further improve the broadcast range of the emergency broadcast body 6.

[0040] Ultimately, in this invention, people only need to hold the handle 1 to realize the forward and reverse rotation of the emergency broadcast body 6 along the circumference, the forward and reverse swing of the emergency broadcast body 6 at the elevation angle, and the use of emergency broadcasting during lifting and lowering. This is beneficial to expand the overall broadcasting range, making the limitations in broadcasting use smaller. Moreover, it can be achieved by simply holding the handle 1 in one position, avoiding the previous situation where the broadcasting device needed to be held and the arm needed to swing back and forth to change the broadcasting range. This reduces the difficulty of emergency broadcasting, makes the overall use effect better, and has a simple structure, which greatly facilitates people's use and is suitable for widespread use.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
