Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a fastener for energy-saving engineering construction. Background Technology

[0002] Fasteners for energy-saving engineering construction are installation and fixing components specifically designed for energy-saving projects, typically used to ensure the stability of energy-saving equipment, materials, or pipelines during construction.

[0003] Currently, photovoltaic solar panels require fasteners for support during use. During installation, they are connected to the ground with screws to achieve the purpose of fixation and support. However, when the photovoltaic support is subjected to wind loads, the stress generated will be concentrated at the connection between the screws and the fasteners. Under repeated wind loads, the anchor bolts at the column base are prone to loosening, thus affecting the stability of the photovoltaic support during fixation. Therefore, it is necessary to propose a fastener for energy-saving engineering construction to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fastener for energy-saving engineering construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fastener for energy-saving engineering construction includes a fixing leg, a fixing cylinder fixedly connected to the upper end of the fixing leg, multiple sets of screws threadedly connected to the outer wall of the fixing leg, and multiple sets of sliders slidably connected inside the fixing leg. The number of sliders is the same as the number of screws, and their positions correspond one-to-one. A sliding cylinder is fixedly connected to the outer wall of each slider, and the sliding cylinder is slidably connected to the fixing leg. A limit rod is slidably connected inside the sliding cylinder. A limit groove is formed on the outer wall of the screw, and the limit rod is inserted into the limit groove. An elastic mechanism is installed inside the sliding cylinder to drive the limit rod to be tightly inserted into the limit groove.

[0007] Preferably, the elastic mechanism includes a spring fixedly connected to the bottom of the slide, and the other end of the spring is fixedly connected to a limiting rod.

[0008] Preferably, the outer wall of one side of each of the multiple sets of sliders is arc-shaped, and a top block is slidably connected inside the fixed leg. The outer wall of the top block is semi-circular, and the outer wall of the top block is in contact with the outer wall of the slider.

[0009] Preferably, the fixed leg is threadedly connected to a threaded rod, one end of which is fixedly connected to the top block, and the other end of which extends into the interior of the fixed cylinder.

[0010] Preferably, the outer wall of the fixed cylinder is provided with a sliding groove, and a rotating block is fixedly connected to the end of the threaded rod.

[0011] Preferably, the outer wall of the limiting rod is in contact with the top and bottom of the limiting groove, and the outer wall of the fixed leg is equipped with multiple sets of reinforcing ribs.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the design of inserting a limiting rod into a limiting groove, combined with the compression effect of a spring, forms a more stable connection structure between the screw and the ground. Especially when the photovoltaic support is subjected to wind load, the limiting rod can effectively limit the displacement of the screw, prevent it from loosening due to repeated external loads, improve the screw's wind load resistance, and ensure the long-term stability of the photovoltaic support.

[0014] 2. When disassembly is required, the threaded rod is operated in reverse, and the spring's restoring force automatically releases the clamping state of the limit rod, thereby releasing the screw's limit. This not only simplifies the disassembly process but also reduces the complexity of operation and tool requirements, greatly improving the efficiency of maintenance and replacement.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3A fastener for energy-saving engineering construction includes a fixed leg 1, a fixed cylinder 2 fixedly connected to the upper end of the fixed leg 1, multiple sets of screws 4 threadedly connected to the outer wall of the fixed leg 1, and multiple sets of sliders 7 slidably connected inside the fixed leg 1. The number of sliders 7 is the same as the number of screws 4, and their positions correspond one-to-one. Each set of sliders 7 has a sliding cylinder 8 fixedly connected to its outer wall, and the sliding cylinder 8 is slidably connected to the fixed leg 1. A limit rod 9 is slidably connected inside the sliding cylinder 8. A limit groove 5 is opened on the outer wall of the screws 4, and the limit rod 9 is inserted into the limit groove 5. An elastic mechanism is installed inside the sliding cylinder 8 to drive the limit rod 9 to be tightly inserted into the limit groove 5. The fixed leg 1 can be connected to the ground by the screws 4, and the position of the screws 4 can be limited by inserting the multiple sets of limit rods 9 into the limit groove 5. By limiting the position, the screws 4 are prevented from shifting, making the connection between the fixed leg 1 and the ground more secure, thereby improving the stability of the entire photovoltaic support.

[0021] The elastic mechanism includes a spring 10 fixedly connected to the bottom of the inner tube 8, and the other end of the spring 10 is fixedly connected to the limiting rod 9. The spring 10 can improve the stability of the limiting rod 9 inserted into the limiting groove 5 and further prevent the screw 4 from being displaced.

[0022] The outer wall of one side of the multiple sets of sliders 7 is arc-shaped. A top block 6 is slidably connected inside the fixed leg 1. The outer wall of the top block 6 is semi-circular and contacts the outer wall of the slider 7. A threaded rod 3 is threadedly connected to the fixed leg 1. One end of the threaded rod 3 is fixedly connected to the top block 6, and the other end of the threaded rod 3 extends into the interior of the fixed cylinder 2. A sliding groove 12 is opened on the outer wall of the fixed cylinder 2. A rotating block 11 is fixedly connected to the end of the threaded rod 3. The outer wall of the limiting rod 9 contacts the top and bottom of the limiting groove 5. Multiple sets of reinforcing ribs are installed on the outer wall of the fixed leg 1.

[0023] In this invention, the device is used as follows: First, the fixing leg 1 is securely installed in a predetermined position using screws 4. Next, the rotating block 11 is rotated, and the rotation of the threaded rod 3 drives the top block 6 to gradually move downwards until the top block 6 contacts multiple sets of sliders 7. At this time, the threaded rod 3 is continued to rotate, and the sliders 7 are pushed outwards. As the sliders 7 move, the limiting rod 9 also moves synchronously until it inserts into the limiting groove 5 and makes tight contact with the inner wall of the groove. As the sliders 7 continue to move outwards, the spring 10 is gradually compressed, thereby enhancing the stability of the limiting rod 9 inserting into the limiting groove 5. This design ensures that the fixing leg 1 remains firm and stable when the photovoltaic support is subjected to external wind loads, preventing the screws 4 from loosening, thereby improving the safety and reliability of the entire support system.

[0024] When it is necessary to disassemble the fixed leg 1, first rotate the rotating block 11 in the opposite direction, driving the threaded rod 3 to rotate in the opposite direction, thereby moving the top block 6 upward. During this process, with the restoring force of the spring 10, the slider 7 gradually retracts inward, while simultaneously driving the slide cylinder 8 to slide inward. This process keeps the limiting rod 9 inside the limiting groove 5, but as the reverse force of the spring 10 gradually weakens, the clamping force of the limiting rod 9 gradually disappears. At this point, by gently pressing the limiting rod 9 inward, its limiting state on the screw 4 can be released. Subsequently, the screw 4 can be easily removed, finally completing the disassembly operation of the fixed leg 1.

[0025] By using screw 4 in conjunction with limit rod 9, not only is a firm connection between screw 4 and fixed leg 1 achieved during installation, but the stability of screw 4 under wind load is also enhanced by limit rod 9 and spring 10.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
