[0001] The utility model relates to the technical field of construction mechanical and electrical construction equipment, and particularly relates to a positioning bracket for the installation of a construction mechanical and electrical project. Background Art

[0002] In a building mechanical and electrical system, a positioning bracket is a core component for realizing the fixed installation of mechanical and electrical equipment such as ventilation ducts, cable trays, and water pipes. Currently, the mainstream positioning brackets generally adopt a rigid fixing structure connected by bolts and nuts. This type of structure relies on the pre-tightening force of the threads to provide connection stiffness. Although it has the advantages of low processing cost and convenient installation, it exposes significant defects in a complex vibration environment.

[0003] The periodic vibration generated during the operation of building mechanical and electrical equipment (such as water pumps, fans, air conditioning units, etc.) will be transmitted to the bolt connection through the equipment bracket, causing the pre-tightening force to decay, and ultimately leading to the loosening or even falling off of the nut;

[0004] Existing fastening methods such as using thread glue curing or self-locking nuts can lock firmly in the short term, but high temperature is required to damage the glue layer or violent disassembly is needed during disassembly, which is not convenient for subsequent maintenance.

Specific implementation manner

[0039] Now, the technical solution of this embodiment will be further elaborated in combination with the drawings and embodiments.

[0040] Embodiment 1, referring to the attached instructions Figures 1 - 12 As shown, a building electromechanical engineering installation positioning bracket includes a horizontal frame 1, screw rods 2 fixedly connected to both ends of the horizontal frame 1, and vertical rods 3 fixedly installed on the screw rods 2; one end of the screw rod 2 is fixedly connected to the ceiling, and the other end is fixedly connected to the horizontal frame 1; during use, one end of the screw rod 2 is fixed to the ceiling, and the other end of the screw rod 2 is fixedly connected to the horizontal frame 1 through a nut.

[0041] It further includes diagonal braces 4 provided at both ends of the horizontal frame 1, and both ends of the diagonal braces 4 are respectively connected to the horizontal frame 1 and the ceiling, so as to achieve the function of auxiliary support;

[0042] Mounting bases 5 are provided at both ends of the diagonal braces 4. A bottom bolt 6 is inserted through between one mounting base 5 and the horizontal frame 1, and a top bolt 7 is inserted through between the other mounting base 5 and the ceiling. Compression nuts 8 are threadedly connected to both the bottom bolt 6 and the top bolt 7;

[0043] A limiting groove 9 for restricting the rotation of the bottom bolt 6 is provided on the horizontal frame 1. The limiting groove 9 is set to be hexagonal, and the bottom bolt 6 is a hexagonal bolt. The hexagonal head of the bottom bolt 6 is inserted into the interior of the limiting groove 9 to restrict the rotation of the bottom bolt 6. One end of the top bolt 7 is fixed inside the ceiling to fix the top bolt 7.

[0044] A bolt shockproof structure is provided inside the mounting base 5, including a plurality of limiting grooves 11 opened at one end of the compression nut 8. The limiting grooves 11 are distributed circumferentially along the axis of the compression nut 8. It also includes a U-shaped frame 12 mounted on the mounting base 5. Slide rails are provided on both sides of the mounting base 5, and both sides of the U-shaped frame 12 are slidably connected to the slide rails. A plurality of limiting teeth 13 that cooperate with the limiting grooves 11 are fixedly provided on the side of the U-shaped frame 12 away from the opening. The limiting teeth 13 are used to insert into the limiting grooves 11 to restrict the rotation of the compression nut 8.

[0045] During use, the U-shaped frame 12 is arranged on the mounting base 5, and the limiting teeth 13 are inserted into the interior of the limiting grooves 11 to reduce the rotation of the compression nut 8 on the bottom bolt 6 and the top bolt 7 due to vibration.

[0046] It further includes a control structure. The control structure is used to control the insertion of the limiting teeth 13 into the limiting grooves 11 or to separate the limiting teeth 13 from the limiting grooves 11. The control structure includes a U-shaped control frame 14 rotatably connected to the mounting base 5. Rotating shafts are provided on both sides of the U-shaped control frame 14, and limiting holes rotatably connected to the rotating shafts are opened on the mounting base 5. Guide grooves 15 are opened on both side walls of the U-shaped control frame 14. The top ends of the guide grooves 15 are inclined in a direction away from the U-shaped frame 12. The guide grooves 15 are set as waist-shaped grooves with semicircular ends at both ends. The bottom end of the guide groove 15 is coaxial with the rotating shaft of the U-shaped control frame 14. The U-shaped frame 12 is slidably connected to the mounting base 5, and guide shafts 16 slidably connected to the guide grooves 15 are fixedly connected to both sides of the U-shaped frame 12.

[0047] A tension spring 17 is installed between the mounting base 5 and the U-shaped frame 12. In the initial state, under the action of the tension spring 17, the U-shaped frame 12 is pulled to move away from the compression nut 8, separating the limiting teeth 13 from the limiting grooves 11.

[0048] During use, the compression nut 8 is sleeved on the bottom bolt 6 and the top bolt 7, and the compression nut 8 is rotated to fix the mounting base 5 on the horizontal frame 1 and the ceiling respectively. After fixing, the U-shaped control frame 14 is rotated towards the opening side of the U-shaped frame 12, causing the guide shafts 16 to slide inside the guide grooves 15. The guide grooves 15 push the guide shafts 16 to slide towards the compression nut 8. At this time, the U-shaped frame 12 pulls the tension spring 17, putting the tension spring 17 in a stretched state, and the limiting teeth 13 are inserted into the interior of the limiting grooves 11. The U-shaped control frame 14 is in a vertical state, and the guide shafts 16 are located at the bottommost end of the guide grooves 15.

[0049] A locking structure for locking the U-shaped control frame 14 is provided on the mounting base 5. The locking structure includes a locking slider 18 slidably connected to the mounting base 5. A self-locking spring 19 is provided between the locking slider 18 and the mounting base 5. An arc-shaped guide block 20 for locking the U-shaped control frame 14 is provided at one end of the locking slider 18 close to the U-shaped control frame 14.

[0050] The side of the U-shaped control frame 14 away from the opening is cylindrical. An arc-shaped groove 21 matching the U-shaped control frame 14 is opened at one end of the arc-shaped guide block 20 close to the mounting base 5.

[0051] During use, rotate the U-shaped control frame 14 towards the opening side of the U-shaped frame 12. When the U-shaped control frame 14 is in a vertical state, the guide shaft 16 is at the bottommost end of the guide groove 15. At this time, the limit tooth 13 is inserted into the limit groove 11. Subsequently, continue to rotate the U-shaped control frame 14 towards the opening side of the U-shaped frame 12. After the U-shaped control frame 14 contacts the arc-shaped guide block 20, continue to rotate the U-shaped control frame 14. The U-shaped control frame 14 pushes the arc-shaped guide block 20 to slide in a direction away from the compression nut 8, compressing the self-locking spring 19. At this time, the guide shaft 16 is restricted at one end of the guide groove 15, thereby restricting the U-shaped frame 12 in the current position until the U-shaped control frame 14 rotates below the arc-shaped guide block 20. Under the action of the self-locking spring 19, the locking slider 18 is pushed to slide in a direction close to the U-shaped control frame 14. The locking slider 18 synchronously drives the arc-shaped guide block 20 to move. At this time, the U-shaped control frame 14 is located below the arc-shaped guide block 20 and restricts it to the current position;

[0052] When disassembly is required, pull the locking slider 18 in a direction away from the U-shaped control frame 14, compressing the self-locking spring 19. At this time, the arc-shaped guide block 20 is separated from the U-shaped control frame 14. First, rotate the U-shaped control frame 14 to a vertical state, and then continue to rotate the U-shaped control frame 14 to swing away from the opening side of the U-shaped frame 12. The guide shaft 16 slides from the bottom of the guide groove 15 to the top of the guide groove 15. At this time, under the action of the guide shaft 16 and the guide groove 15, the U-shaped control frame 14 is pulled to swing away from the opening side of the U-shaped frame 12 to the limit position. Under the action of the tension spring 17, the U-shaped frame 12 is pulled to move in a direction away from the compression nut 8, and the limit tooth 13 is separated from the limit groove 11. Subsequently, a wrench can be used to remove the compression nut 8 from the bottom bolt 6 and the top bolt 7.

[0053] Embodiment 2, refer to the attached drawings of the specification Figure 4 and Figure 10, tension sliders 22 are slidably connected to both ends of the diagonal strut 4. Guide chutes are provided on the side walls at both ends of the diagonal strut 4. Sliders that are slidably connected to the guide chutes are provided on the tension sliders 22. This setting enables the tension sliders 22 to slide inside the diagonal strut 4. The ends of the tension sliders 22 that are away from each other are respectively rotatably connected to the mounting base 5;

[0054] A bidirectional threaded rod 23 is rotatably connected inside the diagonal strut 4. The two tension sliders 22 are respectively threadedly connected to both ends of the bidirectional threaded rod 23. The thread directions at both ends of the bidirectional threaded rod 23 are opposite. Rotating the bidirectional threaded rod 23 controls the two tension sliders 22 to slide in the direction of approaching or separating from each other.

[0055] A worm gear 24 is fixedly connected to the bidirectional threaded rod 23. A worm 25 that meshes with the worm gear 24 is rotatably connected inside the diagonal strut 4.

[0056] During use, rotate the worm 25 to drive the worm gear 24 to rotate, thereby driving the bidirectional threaded rod 23 to rotate. At this time, pull the two tension sliders 22 to slide in the direction of approaching each other, so as to realize tensioning of the diagonal strut 4, improve the stability of the cross frame 1, reduce the shaking of the cross frame 1, and at the same time lock the bidirectional threaded rod 23 in the current position through the worm gear 24 and the worm 25.

[0057] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
