Description

Technical Field

[0001] This invention relates to the field of signal transmission device technology, and more particularly to a portable signal transmission device. Background Technology

[0002] When using signal transmitters, they are usually placed inside a signal transmission device, which is then installed in a certain location for use. With the development of society and the economy, signal transmission devices have become increasingly portable. In the case of existing portable signal transmitters, people place the base on a flat surface to support the transmitter. However, since the area around the base is mostly open, it is difficult to increase the contact area between the base and the ground, thus making it difficult to improve the stability of the base. If the signal transmitter tipes over, it will shake and be damaged.

[0003] Therefore, a portable signal transmission device that can improve the stability of the base is now being developed. Summary of the Invention

[0004] In order to overcome the shortcomings of the above-mentioned devices, which cannot increase the contact area between the base and the ground, and thus make it difficult to improve the stability of the base, the technical problem of the present invention is to provide a portable signal transmission device that can improve the stability of the base.

[0005] The technical embodiment of the present invention is as follows: a portable signal transmission device, comprising:

[0006] The base and handles are provided, with multiple handles evenly connected to the outer wall of the base along the circumferential direction.

[0007] A closed cover plate is rotatably connected to the upper rear part of the base;

[0008] Electromagnetic lock, with an electromagnetic lock connected to the upper front side of the base;

[0009] The first guide seat is connected to the upper left side of the inner wall of the base;

[0010] A placement seat is slidably connected to the first guide seat;

[0011] Signal enhancement mechanism, the base is equipped with a signal enhancement mechanism;

[0012] The signal enhancement mechanism includes a body stabilization mechanism. The signal transmitter is placed on the mounting base, and then the mounting base is moved by the signal enhancement mechanism to enhance the signal. At the same time, the body stabilization mechanism improves the stability of the base.

[0013] More preferably, the signal enhancement mechanism includes:

[0014] Dual-axis motor; a dual-axis motor is connected to the middle of the inner wall of the base.

[0015] The second guide seat is connected to two second guide seats on the upper right side of the inner right wall of the base;

[0016] The first lead screw is rotatably connected between the two second guide seats, and the placement seat is threadedly connected to the first lead screw.

[0017] The transmission component is connected to the output shaft on the upper side of the dual-axis motor. The dual-axis motor drives the first lead screw to rotate through the transmission component, which in turn drives the placement seat and the signal transmitter to move upward, thereby amplifying the signal of the signal transmitter.

[0018] More preferably, the fuselage stabilization mechanism includes:

[0019] The second lead screw is connected to the output shaft on the lower side of the dual-axis motor. The lower part of the second lead screw is rotatably connected to the inner bottom wall of the base.

[0020] The first lifting frame is connected to the second screw via a threaded connection;

[0021] The outer wall of the first lifting frame is uniformly and slidably connected with multiple connecting slots along the circumferential direction.

[0022] Sliding blocks are connected to the lower side of the connecting groove plate;

[0023] The base has three sets of guide frames evenly connected along the circumference. Each set has two guide frames, and the position of each set of guide frames corresponds to the position of the sliding block. The guide frames and sliding blocks of each corresponding set are slidably connected. The second lead screw is driven to rotate by a dual-axis motor, which moves the first lifting frame upward, thereby pressing the connecting groove plate and causing the sliding block to move outward and unfold, thus improving the stability of the base.

[0024] More preferably, it also includes a device protection mechanism for clamping and limiting the signal transmitter, the device protection mechanism including:

[0025] Guide columns are symmetrically connected to the left and right sides of the top wall of the seat.

[0026] The second lifting frame is slidably connected between the guide columns;

[0027] The first return spring is connected to the lower side of the second lifting frame. The lower side of the first return spring is connected to the upper side of the placement seat. The first return spring is sleeved on the guide column.

[0028] Mounting blocks: Mounting blocks are symmetrically connected to both sides of the second lifting frame.

[0029] The first limiting component is rotatably connected between the two mounting blocks on the left side, and also rotatably connected between the two mounting blocks on the right side.

[0030] Torque springs are connected to the mounting blocks on both the front and rear sides that are close to each other. The torsion springs on both the front and rear sides that are close to each other are connected to the adjacent first limiting member. The torsion springs are all fitted on the first limiting member.

[0031] The mounting bracket has fixed brackets on both the left and right sides of the top wall of the seat.

[0032] The rotating component and the first limiting component both pass through the mounting block. The rotating component is connected to both the front and rear sides of the first limiting component. The second lifting frame moves downward under the gravity of the signal transmitter, which drives the first limiting component and the rotating component to move downward. Then, the rotating component rotates upward under the action of the fixed frame, which in turn drives the first limiting component to rotate upward, clamping and limiting the signal transmitter.

[0033] More preferably, it also includes an auxiliary stabilizing mechanism for placing the auxiliary base, the auxiliary stabilizing mechanism including:

[0034] The base has multiple guide supports evenly connected along the circumference on its inner bottom wall.

[0035] Connectors are slidably connected to both the connectors and the guide brackets, and the inner side of each connector is connected to the first lifting frame.

[0036] The connecting rod and the outer side of the connecting piece are rotatably connected to the connecting rod;

[0037] Mounting brackets: Multiple mounting brackets are evenly bolted to the lower side of the base along the circumferential direction, and the positions of the mounting brackets correspond to the positions of the guide brackets.

[0038] Rotating rods are rotatably connected to the outer side of the mounting frame. The rotating rods are rotatably connected to the upper side of the corresponding connecting rods. The first lifting frame drives the connecting rods to move upward, which will push the rotating rods to rotate and unfold outward, providing auxiliary support for the base.

[0039] More preferably, it also includes a cable limiting mechanism for limiting the cable, the cable limiting mechanism including:

[0040] The connecting brackets are symmetrically connected to both the front and rear sides of the top wall of the second lifting frame.

[0041] The second limiting member is slidably connected between the two connecting brackets on the front side, and the second limiting member is also slidably connected between the two connecting brackets on the rear side.

[0042] The second reset spring is connected to the upper part of the connecting bracket. The lower side of the second reset spring is connected to the adjacent second limiting member. The second reset spring is sleeved on the second limiting member. Under the action of the second reset spring, the second limiting member presses and limits the cable.

[0043] More preferably, it also includes a cushioning mechanism for damping and absorbing shock on the base, the cushioning mechanism including:

[0044] Buffer blocks are evenly and slidably connected to the bottom of the base along the circumference.

[0045] The third return spring is connected to the upper part of the buffer block. The lower side of the third return spring is connected to the inner bottom wall of the base. The third return spring is sleeved on the buffer block. The buffer block buffers and reduces shock on the base under the action of the third return spring.

[0046] More preferably, an anti-slip pad is provided on the underside of the buffer block.

[0047] The beneficial effects are as follows: By rotating the first lead screw, the placement base can automatically move the signal transmitter upwards, thereby enhancing the signal transmitted by the signal transmitter. At the same time, the connecting slot plate and sliding block move outwards and unfold under the action of the first lifting frame, thereby increasing the contact area between the base and the ground and thus improving the stability of the base. The first limiting member can clamp and limit the signal transmitter, preventing the signal transmitter from shaking or bumping during the movement of the device. The outward rotation of the rotating rod can assist in the stable placement of the base, thereby further improving the stability of the base. Attached Figure Description

[0061] The above solution will be further explained below with reference to specific embodiments.

[0062] A portable signal transmission device, such as Figures 1-3 As shown, it includes: a base 1 and handles 2, with three handles 2 evenly fixedly connected to the outer wall of the base 1 along the circumferential direction; a closed cover 3, which is rotatably connected to the upper rear side of the base 1; an electromagnetic lock 4, which is connected to the upper front side of the base 1 and can lock the closed cover 3; a first guide seat 5, which is connected to the upper left side of the inner wall of the base 1; a placement seat 6, which is slidably connected to the first guide seat 5 for placing a signal transmitter; a signal enhancement mechanism 7, which is provided on the base 1 for moving the placement seat 6; and a body stabilization mechanism 8, which is provided on the signal enhancement mechanism 7 for improving the stability of the base 1.

[0063] like Figure 3 and Figure 4 As shown, the signal enhancement mechanism 7 includes: a dual-axis motor 71, which is fixedly connected to the middle of the inner wall of the base 1; two second guide seats 74, which are connected to the upper right side of the inner wall of the base 1; a first lead screw 73, which is rotatably connected between the two second guide seats 74, and the placement seat 6 is threadedly connected to the first lead screw 73; and a transmission assembly 72, which is connected to the output shaft of the dual-axis motor 71. The transmission assembly 72 consists of two transmission wheels and a transmission belt. The transmission wheels are connected to the output shaft of the dual-axis motor 71, and the lower part of the first lead screw 73 is also connected to the transmission wheels. A transmission belt is wound between the two transmission wheels.

[0064] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the body stabilization mechanism 8 includes: a second lead screw 81, which is connected to the output shaft of the dual-axis motor 71, and the lower part of the second lead screw 81 is rotatably connected to the inner bottom wall of the base 1; a first lifting frame 82, which is threadedly connected to the second lead screw 81; a connecting slot plate 83, which is slidably connected to the outer wall of the first lifting frame 82 along the circumferential direction with three connecting slot plates 83; a sliding block 84, which is connected to the lower side of each connecting slot plate 83; and a guide frame 85, which is slidably connected to the bottom wall of the base 1 along the circumferential direction with three sets of guide frames 85, each set having two guide frames 85, the position of each set of guide frames 85 corresponding to the position of the sliding block 84, and each set of guide frames 85 being slidably connected to the sliding block 84.

[0065] This device can be used to carry the signal transmitter. First, the electromagnetic lock 4 is unlocked, allowing the cover 3 to unlock. Then, the cover 3 is rotated upwards to open, and the signal transmitter is placed on the base 6. After placement, the cover 3 is rotated downwards to close, and then locked using the electromagnetic lock 4. The device can then be moved using the handle 2, making it easy to carry. When the signal transmitter needs to be used, the cover 3 is rotated upwards to open, and then... When the dual-axis motor 71 is turned on, the output shaft on the upper side of the dual-axis motor 71 rotates, driving the transmission assembly 72 and the first lead screw 73 to rotate. The rotation of the first lead screw 73 causes the placement base 6 to move automatically upward, thereby driving the signal transmitter upward, which enhances the signal of the signal transmitter. At the same time, the rotation of the output shaft on the lower side of the dual-axis motor 71 drives the first lifting frame 82 to move upward. During the upward movement of the first lifting frame 82, the connecting slot plate 83 moves outward and unfolds, driving the sliding block 84 to move outward. This increases the contact area between the base 1 and the ground, thereby improving the stability of the base 1. Afterwards, the dual-axis motor 71 is turned off, and the signal transmitter can then be used. Once the signal transmitter is in use, the output shafts on both sides of the dual-axis motor 71 are reversed. The upper output shaft reverses, causing the transmission assembly 72 and the first lead screw 73 to reverse as well. The reversal of the first lead screw 73 causes the placement seat 6 to move downwards and reset, thereby moving the signal transmitter downwards to retract. Simultaneously, the lower output shaft reverses, causing the second lead screw 81 to reverse as well. The reversal of the second lead screw 81 causes the first lifting frame 82 to move downwards and reset. The downward movement of the first lifting frame 82 pulls the connecting slot plate 83 towards... The inner side moves and resets. The connecting slot plate 83 moves inward, driving the sliding block 84 to move inward and reset. Then, the dual-axis motor 71 is turned off. Next, the closing cover plate 3 is rotated downward to close. Then, the device can be stored. Repeating the above operation, the first lead screw 73 is rotated, so that the placement seat 6 can push the signal transmitter to move automatically upward. This can enhance the signal transmitted by the signal transmitter. At the same time, the connecting slot plate 83 and the sliding block 84 move outward and unfold under the action of the first lifting frame 82. This can increase the contact area between the base 1 and the ground, thereby improving the stability of the base 1.

[0066] like Figure 3 , Figure 7 and Figure 8As shown, it also includes a device protection mechanism 9 for clamping and limiting the signal transmitter. The device protection mechanism 9 includes: guide posts 91, with guide posts 91 symmetrically connected to the left and right sides of the top wall of the placement seat 6; a second lifting frame 92, which is slidably connected to the guide posts 91; four first return springs 93 connected to the lower side of the second lifting frame 92, with the lower side of each first return spring 93 connected to the upper side of the placement seat 6, and each first return spring 93 sleeved on the guide posts 91; mounting blocks 94, with mounting blocks 94 symmetrically connected to the left and right sides of the second lifting frame 92; and a first limiting member 95, with the two mounting blocks 94 on the left side... A first limiting member 95 is rotatably connected between the two mounting blocks 94 on the right side, and a first limiting member 95 is also rotatably connected between the two mounting blocks 94 on the right side. The first limiting member 95 can clamp and limit the signal transmitter. Torsion springs 96 are connected to the sides of the mounting blocks 94 on both the front and rear sides, and the sides of the torsion springs 96 on both the front and rear sides are connected to the adjacent first limiting member 95. The torsion springs 96 are all fitted on the first limiting member 95. Fixing brackets 97 are connected to the top wall of the placement seat 6 on both the left and right sides. Rotating members 98 are connected to the first limiting member 95 on both the front and rear sides.

[0067] When it is necessary to clamp and limit the signal transmitter, firstly, the signal transmitter is placed on the second lifting frame 92. Then, the second lifting frame 92 moves downwards under the weight of the signal transmitter. At this time, the first return spring 93 is compressed. The downward movement of the second lifting frame 92 causes the mounting block 94 and the first limiting member 95 to move downwards. The downward movement of the first limiting member 95 causes the rotating member 98 to move downwards. When the rotating member 98 contacts the fixed frame 97, the rotating member 98 rotates upwards under the action of the fixed frame 97. The upward rotation of the rotating member 98 causes the first limiting member 95 to rotate upwards. At this time, the torsion spring 96 is twisted. The upward rotation of the first limiting member 95 clamps and limits the signal transmitter, preventing it from shaking or shifting. When the signal transmitter needs to be removed, a force greater than that of the torsion spring 96 is used to remove it. After the signal transmitter is removed, the second lifting frame 92 moves upward and resets under the action of the first reset spring 93. The upward movement of the second lifting frame 92 drives the mounting block 94 and the first limiting member 95 to move upward. The upward movement of the first limiting member 95 drives the rotating member 98 to move upward. When the rotating member 98 separates from the fixed frame 97, the first limiting member 95 rotates downward and resets under the action of the torsion spring 96. The downward rotation of the first limiting member 95 drives the rotating member 98 to rotate downward and reset. Repeating the above operation, the signal transmitter can be clamped and limited by the first limiting member 95, so that the signal transmitter can be prevented from shaking or bumping during the movement of the device.

[0068] like Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, it also includes an auxiliary stabilizing mechanism 10 for placing the base 1. The auxiliary stabilizing mechanism 10 includes: guide brackets 101, three guide brackets 101 are evenly connected to the inner bottom wall of the base 1 along the circumferential direction; connectors 102, connectors 102 are slidably connected to the guide brackets 101, and the inner side of each connector 102 is connected to the first lifting frame 82; connecting rods 103, connecting rods 103 are rotatably connected to the outer side of each connector 102; mounting brackets 105, three mounting brackets 105 are evenly bolted to the lower side of the base 1 along the circumferential direction, and the positions of the mounting brackets 105 correspond to the positions of the guide brackets 101; and rotating rods 104, rotating rods 104 that can further improve the stability of the base 1 are rotatably connected to the outer side of each mounting bracket 105, and the rotating rods 104 are rotatably connected to the upper side of the corresponding connecting rods 103.

[0069] When the base 1 needs to be placed stably on the ground, firstly, when the first lifting frame 82 moves upward, it causes the connecting piece 102 to move upward. The upward movement of the connecting piece 102 causes the connecting rod 103 to rotate outward. The outward rotation of the connecting rod 103 compresses the rotating rod 104 to rotate outward and unfold, thus further improving the stability of the device. When the first lifting frame 82 moves downward, it causes the connecting piece 102 to move downward and reset. The downward movement of the connecting piece 102 causes the connecting rod 103 to rotate inward and reset. The inward rotation of the connecting rod 103 pulls the rotating rod 104 to rotate inward and retract. Repeating the above operations, the rotating rod 104 rotates outward and unfolds, which helps to place the base 1 stably, thus further improving the stability of the base 1.

[0070] like Figure 3 and Figure 11 As shown, it also includes a cable limiting mechanism 11 for limiting the cable. The cable limiting mechanism 11 includes: a connecting bracket 111, which is symmetrically connected to both the front and rear sides of the top wall of the second lifting frame 92; a second limiting member 113, which is slidably connected between the two connecting brackets 111 on the front side and between the two connecting brackets 111 on the rear side, and the second limiting member 113 can press and limit the cable; and a second return spring 112, which is connected to the upper part of the connecting bracket 111, and the lower side of the second return spring 112 is connected to the adjacent second limiting member 113, and the second return spring 112 is sleeved on the second limiting member 113.

[0071] When it is necessary to limit the cable of the signal transmitter, the cable is passed through the front and rear positions of the second lifting frame 92. As the number of cables increases, the second limiting member 113 will be pushed to move upward. At this time, the second return spring 112 is compressed, thus limiting the cable and preventing it from becoming tangled. When it is necessary to remove the cable, it can be removed directly. Then, the second limiting member 113 moves downward to reset under the action of the second return spring 112. Repeating the above operation, the second limiting member 113 can press and limit the cable to prevent it from becoming tangled.

[0072] like Figure 3 and Figure 12 As shown, it also includes a buffer mechanism 12 for cushioning and damping the base 1. The buffer mechanism 12 includes: a buffer block 122, which is uniformly slidably connected to the bottom of the base 1 along the circumferential direction; a third return spring 121, which is connected to the upper part of the buffer block 122. The lower side of the third return spring 121 is connected to the inner bottom wall of the base 1. The third return spring 121 is sleeved on the buffer block 122. The lower side of the buffer block 122 is provided with an anti-slip pad to increase the friction between it and the ground.

[0073] When the base 1 needs to be cushioned and damped, when the base 1 is placed on the ground, the buffer block 122 will move upward under the action of the weight of the base 1. At this time, the third return spring 121 is stretched, which can cushion and dampen the base 1. When the base 1 is separated from the ground, the buffer block 122 moves downward and resets under the action of the third return spring 121. By repeating the above operation, the buffer block 122 and the third return spring 121 cooperate with each other to cushion and dampen the base 1, thereby reducing the sway rate of the base 1.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
