Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically to a conveniently stored orifice bracket. Background Technology

[0002] Hole drilling inspection is a common quality control method in engineering construction. The hole diameter is measured by lowering a measuring umbrella through the borehole opening and then raising it. The pulley support at the borehole opening is an essential auxiliary tool for this inspection.

[0003] Existing orifice pulley brackets are designed to be much longer than the minimum usable standard. This is to allow for installation on the piling machine at the orifice and to ensure stability during testing. However, the excessive length of the brackets creates difficulties for handling and storage. Conversely, conventional solutions to this problem conflict with ensuring stability during installation and use.

[0004] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0005] The purpose of this invention is to provide a convenient storage orifice bracket to overcome the aforementioned shortcomings and deficiencies of the existing technology.

[0006] A conveniently stored orifice bracket includes: a pulley structure, a reinforcing rib, an outer frame, an internal pull rod, and a limiting structure. The outer frame is hollow and symmetrically arranged. The bottom of the pulley structure is connected to the top of the outer frame. The reinforcing rib is connected to the outer frame. The internal pull rod is located inside the outer frame. The limiting structure is located at the outlet end of the outer frame.

[0007] The internal pull rod includes a first pull rod, a second pull rod, a third pull rod, and a hinge. The first and second pull rods have the same structure. The first pull rod is connected to the second pull rod via the hinge. The third pull rod is higher than the first and second pull rods. The third pull rod is connected to the second pull rod and is located within the outer frame. When in use, the third pull rod is connected to the limiting structure.

[0008] Furthermore, the pulley structure includes: a pulley base, a pulley bracket, and a pulley. The pulley base is connected to the outer frame, the bottom end of the pulley bracket is located on the pulley base, and the pulley is connected to the top end of the pulley bracket.

[0009] The beneficial effects of this utility model are:

[0010] Compared with traditional technologies, this utility model provides a convenient storage orifice bracket. Through an inner and outer nested structure and a hinged folding design, it achieves a quick conversion between use and storage states. Stable support is achieved without a complex locking mechanism, improving the product's practicality and durability. Attached image description:

[0014] Pulley structure 100, pulley base 110, pulley bracket 120 and pulley 130.

[0015] The components include a reinforcing rib 200, an outer frame 300, an internal pull rod 400, a first pull rod 410, a second pull rod 420, a third pull rod 430, a hinge 440, and a limiting structure 500. Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0017] Example 1

[0018] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a structural diagram of the present invention in its stored state.

[0019] like Figure 1 As shown, a conveniently stored orifice bracket includes: a pulley structure 100, a reinforcing rib 200, an outer frame 300, an internal pull rod 400, and a limiting structure 500. The outer frame 300 is a hollow structure and is symmetrically arranged. The bottom of the pulley structure 100 is connected to the top of the outer frame 300. The reinforcing rib 200 is connected to the outer frame 300. The internal pull rod 400 is located inside the outer frame 300. The limiting structure 500 is located at the outlet end of the outer frame 300.

[0020] The internal pull rod 400 includes a first pull rod 410, a second pull rod 420, a third pull rod 430, and a hinge 440. The first pull rod 410 and the second pull rod 420 have the same structure. The first pull rod 410 is connected to the second pull rod 420 through the hinge 440. The third pull rod 430 is higher than the first pull rod 410 and the second pull rod 420. The third pull rod 430 is connected to the second pull rod 420. The third pull rod 430 is located inside the outer frame 300. When in use, the third pull rod 430 is connected to the limiting structure 500.

[0021] The pulley structure 100 includes a pulley base 110, a pulley bracket 120, and a pulley 130. The pulley base 110 is connected to the outer frame 300. The bottom end of the pulley bracket 120 is located on the pulley base 110, and the pulley 130 is connected to the top end of the pulley bracket 120.

[0022] like Figure 2 As shown, the usage method of this utility model is no different from the existing structure. This utility model mainly improves the structure for ease of use and storage. When needed, the first pull rod 410 is rotated 180°, placing it and the second pull rod 420 in a coaxial horizontal position. The hinge 440 is the connecting member used to fix them together. Depending on actual needs, the first pull rod 410 and the second pull rod 420 can move within the hollow outer frame 300. At this time, the third pull rod 430 is fixed by the limiting structure 500, preventing the pull rod from completely disengaging. When needing to be stored, the first pull rod 410 is rotated 180°, positioning it below the outer frame 300. The function of the second pull rod 420 is to ensure that the hinge 440 can follow a certain structure into the outer frame 300 during storage, thereby protecting it.

[0023] In summary, this utility model cleverly utilizes the hollow structure of the outer frame 300, allowing the pull rod to be completely hidden when not in use, realizing the design concept of "hidden invisibly" and occupying almost no extra space when stored. The hinged pull rod system employs simple mechanical principles, achieving complex functional transformation through a 180° flip. This design avoids complex locking mechanisms, achieving stable support through a purely mechanical structure. The second pull rod is not only a functional component but also serves to protect the hinge, serving two purposes. When the system is folded, the hinge naturally enters the outer frame, eliminating the need for specially designed protective covers or other additional components. The cooperation between the limiting structure and the third pull rod embodies the design wisdom of "self-limiting without locking." This passive limiting method is more reliable than active locking, reducing operational steps and the possibility of malfunction. The entire system can be transformed from its use state to its storage state with just a simple flipping action.

[0024] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
