Description

Technical Field

[0001] This utility model relates to the field of engineering equipment technology, and in particular to an adjustable bolt box. Background Technology

[0002] In projects combining prefabricated steel structures and concrete structures, reinforced concrete precast columns serve as the core of vertical load-bearing. The pre-embedded bolts at the top of the precast columns play a crucial role in positioning, anchoring, and transmitting force to the steel roof truss. The bolts need to be precisely embedded into the reserved bolt holes at the ends of the steel roof truss, and the rigid connection between the roof truss and the column is achieved by tightening with nuts, ensuring the effective transmission of vertical loads, horizontal wind loads, and seismic forces. As a result, an adjustable bolt box has emerged.

[0003] The core function of traditional adjustable bolt boxes on the market is to achieve precise adjustment of bolt translation in a specific direction and stable fixation after adjustment through mechanical structure coordination. As the core protective component, the bolt housing is mostly made of high-strength engineering materials, which have excellent moisture-proof and corrosion-proof performance. The bolt box can maintain structural stability in humid or dusty environments and avoid the decline in protective ability due to material aging.

[0004] In existing adjustable bolt boxes, the bolts are typically moved via an internal motor and interlocking mechanism during adjustment. Since the bolts are then sealed with cement after movement, the device is disposable. This design is expensive to manufacture, leading to unnecessary waste and increased project costs. To address the problem of overly complex internal structures in existing adjustable bolt boxes, a new adjustable bolt box design is proposed to solve these issues. Utility Model Content

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, when adjustment begins, the one-way wheel rotates and drives the threaded rod to rotate synchronously. The threaded rod drives the vertical or horizontal sliding block to slide internally.

The connecting pin pushes the one-way claw to move, thereby driving the one-way wheel to achieve one-way rotation, ensuring that the adjustment process is carried out stably in the preset direction and avoiding reverse rotation from affecting the adjustment accuracy.

A vertical sliding block 43 is slidably connected to the inner wall of the inner mechanical box 3. The inner wall of the inner mechanical box 3 provides a sliding track for the vertical sliding block 43. An upper mechanical box 44 is fixedly connected to the top of the vertical sliding block 43. The top of the vertical sliding block 43 drives the upper mechanical box 44 to move synchronously. A horizontal sliding block 45 is slidably connected to the inner wall of the upper mechanical box 44. The inner wall of the upper mechanical box 44 provides sliding space for the horizontal sliding block 45. A limit component 46 is fixedly connected to the outer wall of the horizontal sliding block 45. The movement of the outer wall of the horizontal sliding block 45 is limited by the limit component 46.

[0041] Specifically, the two threaded rods 41 of the adjustment mechanism 4 serve as core transmission components to achieve precise power transmission. The one-way wheel 42 ensures stable rotation direction and improves transmission reliability. The vertical sliding block 43 slides smoothly within the internal mechanical box 3, driving the upper mechanical box 44 to move synchronously and achieve flexible vertical adjustment. The horizontal sliding block 45 slides freely within the upper mechanical box 44, expanding the adjustment range.

The outer wall of the vertical sliding block 43 is fixedly connected to two vertical limiting blocks 462.

The threaded rod 41 drives the horizontal sliding block 45 to move through the thread. The outer wall of the other threaded rod 41 is slidably connected to the inner wall of the upper mechanical box 44. The threaded rod 41 can slide on the inner wall of the upper mechanical box 44. The bottom of the bolt column 6 is fixedly connected to the top of the horizontal sliding block 45. The top of the horizontal sliding block 45 drives the bolt column 6 to adjust synchronously. The outer wall of the vertical sliding block 43 is slidably connected to the inner wall of the inner mechanical box 3. The vertical sliding block 43 slides smoothly on the inner wall of the inner mechanical box 3. The outer wall of the upper mechanical box 44 is slidably connected to the inner wall of the inner mechanical box 3. The upper mechanical box 44 can slide on the inner wall of the inner mechanical box 3.

[0045] Specifically, one threaded rod 41 drives the vertical sliding block 43 to move smoothly through the thread, realizing vertical adjustment. The other threaded rod 41 drives the horizontal sliding block 45 to move precisely through the thread, completing horizontal adjustment. The threaded rod 41 slides smoothly in the upper mechanical box 44, ensuring flexible adjustment. The bolt column 6 is adjusted synchronously with the horizontal sliding block 45, with precise positioning. The vertical sliding block 43 and the upper mechanical box 44 slide smoothly in the inner mechanical box 3, improving the overall adjustment efficiency and stability.

[0046] Reference Figure 1 and Figure 4 The operating mechanism 5 includes a positioning post 51, which serves as the positioning reference component. The outer wall of the positioning post 51 is slidably connected to the inner wall of the one-way wheel 42, forming a sliding fit between the outer wall of the positioning post 51 and the inner wall of the one-way wheel 42. A connecting block 52 is fixedly connected to one side of the positioning post 51, providing fixed support for the connecting block 52. A connecting handle 53 is fixedly connected to the top of the connecting block 52, facilitating force application through the connecting handle 53. A connecting post 54 is fixedly connected to one side of the connecting block 52, providing a fixed position for the connecting post 54. A one-way claw 55 is slidably connected to the outer wall of the connecting post 54, providing sliding space for the one-way claw 55.

[0047] Specifically, the positioning column 51 of the operating mechanism 5 slides with the one-way wheel 42 to ensure precise operation, the connecting block 52 provides stable support for each component, the connecting handle 53 facilitates force application, the connecting column 54 provides sliding space for the one-way claw 55, and the one-way claw 55 ensures reliable one-way transmission, improving the convenience and efficiency of operation.

[0048] The outer walls of the two horizontal limiting blocks 461 are slidably connected to the inner wall of the upper mechanical box 44, and the horizontal limiting blocks 461 achieve horizontal limiting on the inner wall of the upper mechanical box 44. The outer walls of the two vertical limiting blocks 462 are slidably connected to the inner wall of the inner mechanical box 3, and the vertical limiting blocks 462 achieve vertical limiting on the inner wall of the inner mechanical box 3. One side of the one-way pawl 55 is slidably connected to one side of the connecting block 52, and the one-way pawl 55 and one side of the connecting block 52 form a sliding fit. One side of the one-way pawl 55 contacts the outer wall of the one-way wheel 42, and the one-way pawl 55 achieves one-way transmission by contacting the outer wall of the one-way wheel 42 on one side.

[0049] Specifically, the horizontal limit block 461 slides within the upper mechanical box 44 to ensure precise horizontal adjustment, while the vertical limit block 462 slides within the inner mechanical box 3 to ensure stable vertical adjustment. The one-way claw 55 and the connecting block 52 work smoothly together, and the contact one-way wheel 42 achieves reliable one-way transmission.

[0050] Reference Figure 1 and Figure 4 The operating mechanism 5 includes a positioning column 51, the outer wall of which is slidably connected to the inner wall of the one-way wheel 42. A connecting block 52 is fixedly connected to one side of the positioning column 51. A connecting handle 53 is fixedly connected to the top of the connecting block 52. A connecting column 54 is fixedly connected to one side of the connecting block 52. A one-way claw 55 is slidably connected to the outer wall of the connecting column 54. The outer walls of the two horizontal limiting blocks 461 are slidably connected to the inner wall of the upper mechanical box 44. The outer walls of the two vertical limiting blocks 462 are slidably connected to the inner wall of the inner mechanical box 3.

[0051] Specifically, the positioning column 51 of the operating mechanism 5 slides with the one-way wheel 42 to ensure stable operation, the connecting handle 53 facilitates the application of force, the connecting column 54 allows the one-way claw 55 to slide smoothly, and the horizontal and vertical limit blocks 462 ensure precise adjustment and improve overall reliability.

[0052] The implementation principle of this application embodiment is as follows: When the adjustment time begins, the one-way wheel 42 rotates, which drives the threaded rod 41 to rotate. The threaded rod 41 drives the vertical sliding block 43 or the horizontal sliding block 45 to slide inside. At this time, the horizontal limiting block 461 and the vertical limiting block 462 restrict the sliding direction of the vertical sliding block 43 and the horizontal sliding block 45 and prevent swaying due to shaking. Finally, the position of the bolt column 6 is adjusted by moving the horizontal sliding block 45.

[0053] When adjustment is required, slide the positioning post 51 onto the inner wall of the one-way wheel 42. Then rotate the connecting handle 53, which in turn drives the connecting block 52 to rotate. The connecting block 52 rotates around the center of the positioning post 51, which in turn drives the connecting post 54 to rotate. The connecting post 54 then pushes the one-way pawl 55 to drive the one-way wheel 42 to rotate in one direction.
