DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying 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.

[0027] Figure 1 It shows the structural diagram of the bidirectional support rod in the utility model. Figure 2 An exploded view of the bidirectional brace in the present invention is shown. Figure 3 A cross-sectional view of a bidirectional strut in the present invention is shown, wherein the bidirectional strut comprises: a driving motor 1 and two push rods symmetrically distributed on both sides of the driving motor 1, namely a first push rod 2 and a second push rod 7. The structures of the first push rod 2 and the second push rod 7 are the same, and the following is a detailed description taking the first push rod 2 as an example; the first push rod 2 here comprises: a fixed shell 21 and a strut 22, and the fixed shell 21 has a accommodating cavity 210, and the strut 22 is inserted in the accommodating cavity 210, and the end of the strut 22 close to the driving motor 1 is connected to the driving motor 1 based on the gear housing 3; the two struts in the embodiment of the present invention are driven by the driving motor 1 to approach each other or the two struts are driven by the driving motor 1 to move away from each other, that is, the strut 22 on the first push rod 2 and the strut on the second push rod 7 are driven by the driving motor 1 to approach each other, or the strut 22 on the first push rod 2 and the strut on the second push rod 7 are driven by the driving motor 1 to move away from each other. The fixed shell 21 is used to limit the moving direction of the strut 22, and the accommodating cavity 210 is used to accommodate the strut 22 so that the strut 22 moves along the inner wall of the accommodating cavity 210. The strut 22 is used to abut against an external vertical or horizontal surface, exerting force from both sides at the same time, so that the entire bidirectional strut is temporarily fixed in the corresponding position.

[0028] Furthermore, the support rod 22 includes: a movable housing 221 and a screw rod 222. The movable housing 221 is provided with a first connecting hole on the end face close to the drive motor 1, and the screw rod 222 is inserted into the movable housing 221 through the first connecting hole. The shape of the movable housing 221 is similar to that of the fixed housing 21, and the size of the movable housing 221 is smaller than that of the fixed housing 21. The fixed housing 21 is used to limit the movement direction of the movable housing 221, ensuring that the movable housing 221 can only move in the horizontal direction, thereby reducing the risk of the movable housing 221 rotating. Secondly, the screw rod 222 is inserted into the movable housing 221. When the screw rod 222 is driven by the motor to rotate, the movable housing 221 moves along the thread on the screw rod 222, thereby changing the position of the movable housing 221 in the fixed housing 21, which is conducive to the movable housing 221 changing its position.

[0029] Furthermore, a fixed block 223 is provided on the end face of the movable housing 221 close to the drive motor 1, and the fixed block 223 is sleeved on the screw rod 222; the fixed block has a second connecting hole, and the first connecting hole and the second connecting hole are located on the same axis. The fixed block 223 is fixedly connected to the movable housing 221, and the fixed block 223 is threadedly connected to the screw rod 222. When the screw rod 222 is driven by the drive motor 1 and rotates, the fixed block 223 moves along the thread of the screw rod 222. When the fixed block 223 moves along the thread of the screw rod 222 away from the drive motor 1, it pushes the movable housing 221 to move away from the drive motor 1, causing the push rod 2 to extend outward and abut against the corresponding wall, thereby increasing the friction between the bidirectional support rod and the wall, reducing the risk of the bidirectional support rod slipping, and improving the stability of the bidirectional support rod.

[0030] Furthermore, each of the push rods has a thread, and the spiral direction of the thread of the push rod is opposite to the spiral direction of the thread of the symmetrically distributed push rod, that is, one of the two symmetrical push rods has a forward thread, and the other push rod has a reverse thread, ensuring that when the two symmetrical push rods rotate, the fixed blocks 223 on the two push rods can move in the opposite direction. In this embodiment, the first push rod 2 has a forward thread and the second push rod 7 has a reverse thread. The first push rod 2 and the second push rod 7 are driven by the drive motor 1 to rotate at the same time. The first push rod 2 rotates, and the fixed block 223 sleeved on the first push rod 2 moves along the forward thread in the direction away from the drive motor 1, thereby pushing the movable shell 221 to move away from the drive motor 1, so that the first push rod 2 extends outward. At the same time, the second push rod 7 rotates, and the fixed block sleeved on the second push rod 7 moves along the reverse thread in the direction away from the drive motor 1, thereby pushing the corresponding connected movable shell to move away from the drive motor 1, so that the second push rod 7 extends outward, achieving the purpose of extending both ends outward at the same time; similarly, when the drive motor 1 rotates in the opposite direction, the first push rod 2 and the second push rod 7 approach each other at the same time, achieving the purpose of contracting both ends at the same time, which is conducive to the simultaneous extension of the two symmetrically distributed push rods and simultaneously abutting against the corresponding wall to provide more stable support. Similarly, when the drive motor 1 rotates, the two symmetrically distributed push rods can be retracted at the same time and leave the corresponding wall at the same time, avoiding the risk of uneven force at both ends causing the bidirectional support rod to tilt, which is conducive to the bidirectional support rod providing more stable support.

[0031] Furthermore, the gear housing 3 includes a driving gear 31 and a driven gear 32, which are meshed with each other; the driving gear 31 is fixedly connected to the output end of the drive motor 1, and the driven gear 32 is fixedly connected to the two push rods 2. When the output end of the drive motor 1 begins to rotate, it drives the driving gear 31 to rotate, and the rotation of the driving gear 31 drives the driven gear 32 to rotate, which in turn drives the two push rods 2 to rotate, so that the two push rods 2 rotate simultaneously, which is conducive to controlling the simultaneous extension or contraction of the bidirectional struts, avoiding the risk of uneven force on the two ends of the bidirectional struts causing the bidirectional struts to tilt, and helping the bidirectional struts provide more stable support.

[0032] Furthermore, a fixing plate 4 is provided on the upper end surface of any of the push rods 2. The fixing plate 4 is connected to the push rod 2 and fixedly connected to the upper end surface of the push rod 2. The fixing plate 4 is used to combine the push rod 2 with other functional components to achieve multifunctional integration. In some embodiments, the fixing plate 4 is combined with a work platform. When construction is required in the shaft, the fixing plate 4 fixes the two-way support rods to the bottom of the work platform. After the work platform is hoisted to a specified height in the shaft, the two-way support rods temporarily fix the work platform at the specified height, allowing construction workers to carry out construction at this height, thereby ensuring the safety of the construction workers.

[0033] Furthermore, a plurality of triangular bosses 41 are provided on the lower end surface of the fixing plate 4, and the plurality of triangular bosses 41 abut against the surface of the push rod 2. In this embodiment, twenty triangular bosses 41 are provided on the lower end surface of the fixing plate 4, of which ten are located on one side of the fixing plate 4, and the other ten are located on the opposite side. A mounting area is formed between the triangular bosses 41 on both sides, and the fixing housing 21 is mounted in the mounting area. The surface of the fixing housing 21 abuts against the plurality of triangular bosses 41. The plurality of triangular bosses 41 exert a force on the fixing housing 21, reducing the risk of the fixing housing 21 rotating during use, which is conducive to maintaining the stability of the bidirectional support rod.

[0034] Furthermore, the fixing plate 4 is provided with a plurality of fixing holes 42, which are distributed along the edge of the fixing plate 4 according to predetermined positions. In this embodiment, the fixing plate 4 is provided with twenty fixing holes 42, which are evenly spaced along the edge of the fixing plate 4. The fixing holes 42 firmly secure the bidirectional brace in the desired position, preventing displacement or loosening due to factors such as vibration and external forces during operation, thereby maintaining the overall performance and reliability of the bidirectional brace. Furthermore, the fixing holes 42 also disperse the stress and pressure on the bidirectional brace, reducing the risk of deformation or damage due to uneven force.

[0035] Furthermore, a fixing bracket 5 is provided on the lower end surface of each push rod 2. The fixing bracket 5 is connected to the push rod 2 and is used to raise the height of the push rod 2. The height of the fixing bracket 5 is greater than the height of the drive motor 1. When the bidirectional support rod is placed on the ground, the fixing bracket 5 supports the push rod 2, so that the push rod 2 is at a certain distance from the ground, preventing the drive motor 1 from directly contacting and rubbing against the ground, which would cause wear of the drive motor 1. This helps reduce the risk of wear of the drive motor 1 and extend the service life of the drive motor 1.

[0036] Furthermore, the bidirectional push rod 2 further includes a support portion 6, which is located at the end of the push rod 2 and is connected to the push rod 2. The support portion 6 is used to increase the contact area between the bidirectional push rod 2 and the corresponding wall surface, thereby increasing the friction between the bidirectional push rod 2 and the corresponding wall surface, reducing the risk of the bidirectional push rod 2 sliding off after contacting the corresponding wall surface, and facilitating the stability of the bidirectional support rod.

[0037] To sum up, the utility model sets two symmetrically distributed push rods, which are driven by the motor to approach or move away from each other at the same time, avoiding the risk of uneven force at both ends causing the bidirectional support rod to tilt, which is conducive to the bidirectional support rod providing more stable support.

[0038] In addition, the above is a detailed introduction to a bidirectional support rod provided in an embodiment of the present invention.
