Description
Technical Field
[0001] This utility model belongs to the field of eccentric buckle technology, and in particular relates to a weather-resistant stainless steel eccentric buckle suitable for outdoor working conditions. Background Technology
[0002] Eccentric buckles, as a quick-connect fixing component, undertake core functions such as tarpaulin fastening, protective net tensioning, and component docking. Their performance directly affects the equipment's sealing performance, safety, and service life. Outdoor working conditions require the equipment to withstand harsh environmental conditions such as wind and rain, alternating high and low temperatures, and ultraviolet radiation. In addition, they need to be able to withstand vibrations during transportation, impacts during loading and unloading, and fatigue wear from repeated opening and closing over a long period of time.
[0003] Chinese patent application CN306905346S discloses an eccentric fastener for an integrated tarpaulin, comprising a main body, a handle, and a hook. The hook has a hook body at its end. The handle is hinged to the main body via a first pin, and the hook is hinged to the main body via a second pin. The handle and hook are located on both sides of the main body. This eccentric fastener for an integrated tarpaulin uses the hook body to secure the edge of the tarpaulin to the edge of the vehicle compartment. The hook can be installed or removed by operating the handle, which is quick and convenient, improving the installation efficiency of the tarpaulin and saving time.
[0004] The above technologies enable rapid installation and disassembly of tarpaulins, and solve the problem of low efficiency in traditional fixing methods by simplifying the operation steps. The eccentric buckle in the existing technology does not have a weather-resistant coating. In outdoor conditions, the water film formed by rain and dew will cause carbon steel to oxidize and rust. At the same time, long-term exposure to ultraviolet rays will cause the metal material to become brittle. After the hinge part rusts, it will become stuck, eventually leading to the inability to open or close or the hook breaking. In addition, the main body of the eccentric buckle in the existing technology is a simple frame structure without shock-absorbing and reinforcing structure, which is prone to deformation when subjected to long-term vibration.
[0005] To address these issues, we offer a weather-resistant stainless steel eccentric buckle suitable for outdoor applications. Utility Model Content
[0006] The purpose of this invention is to provide a weather-resistant stainless steel eccentric buckle suitable for outdoor working conditions. By combining a weather-resistant coating and a rubber plate, it solves the problems of insufficient weather and corrosion resistance of existing eccentric buckles, which leads to the inability to open and close the eccentric buckle, and the easy deformation of the device when the eccentric buckle is subjected to long-term vibration.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0008] This utility model relates to a weather-resistant stainless steel eccentric buckle suitable for outdoor working conditions. It includes a main frame, with a first connecting rod on one side of the inner cavity of the main frame. A locking component is provided on the surface of the first connecting rod. The two sides of the main frame are vertical support walls with arc-shaped inner surfaces and folded edges. A first hollow is formed on one side of the bottom of the main frame, with equidistant hollows. The entire structure is a one-piece molded stainless steel structure. A rubber plate is fixedly connected to the other side of the bottom of the main frame. A reset mechanism is provided on one side of the support wall. The outer surface of the main frame and the inner surface of the side arms are coated with a weather-resistant coating. The main frame has a trough-like structure and is integrally cast from stainless steel. Its left and right sides extend integrally to form support walls perpendicular to the bottom. A horizontally arranged first connecting rod is fixed in the middle of the left inner wall of the inner cavity of the main frame. Equidistant first hollows are formed on one side of the bottom of the main frame. The hollows are rectangular with rounded edges, facilitating the insertion of the pull rod. The rope provides regular points of contact, and the pull rope can form a fixed structure with the locking components, improving the fixation reliability in strong winds and vibrations outdoors. The rounded corner design can avoid severe friction between the rope and the hollowed-out edges, preventing the pull rope from wearing and breaking. The size of the rubber plate matches the bottom of the main frame, so that the vibration load is evenly buffered when it is transmitted, avoiding uneven local force that could lead to buffer failure. It can also maximize the contact area with the mounting surface, increase friction, and further prevent the overall frame from shifting due to outdoor vibrations. At the same time, it isolates the metal from direct collision with the contact parts, reducing scratches and vibration noise. A second connecting rod parallel to the first connecting rod is welded to the inner center of the right support wall. The outer surface of the main frame, the inner surfaces of the two support walls, and the exposed part of the first connecting rod are all coated with a weather-resistant coating. The coating completely covers all metal surfaces, which can isolate rainwater, salt, and ultraviolet rays from direct contact with the metal surfaces, delay corrosion and aging, avoid local corrosion caused by missed coating, ensure consistent weather resistance of all parts, and adapt to different harsh outdoor working conditions.
[0009] The present invention is further configured such that the locking assembly includes a stabilizing plate, one side of which is movably connected to the surface of the first connecting rod via a bearing, a fixing tube is sleeved on one side of the surface of the first connecting rod, a second hollow is provided on the top of the stabilizing plate, the second hollows are equidistant from each other, a pressure tongue is provided on one side of the stabilizing plate, the surface of the pressure tongue is provided with a first anti-slip texture, the second hollow can serve as an auxiliary rope threading point, and cooperate with the first hollow to form a multi-dimensional fixation, the first anti-slip texture can form a surface contact anti-slip locking with the second anti-slip texture, which can effectively resist relative sliding caused by vibration and improve the locking reliability.
[0010] The present invention is further configured such that a mounting hole is provided on one side of the top of the main frame, and the number of mounting holes is two. The symmetrical mounting holes can adapt to the needs of outdoor installation and can effectively limit the rotation and displacement of the frame compared with the existing single-hole installation.
[0011] The present invention is further configured such that a mounting plate is provided on the other side of the top of the main frame, and a threaded rod is fixedly connected to one side of the mounting plate. There are two threaded rods, one side of which passes through the mounting hole and is connected to a nut by threads. The two threaded rods pass through the mounting hole and are fixed by the nut to form a symmetrical installation structure. During installation, the distance between the main frame and the mounting base can be changed by adjusting the tightness of the nut, thereby adapting to mounting bases of different thicknesses. At the same time, the installation load can be evenly distributed to two stress points, avoiding stress concentration when installing a single rod. After long-term outdoor stress or vibration, the threaded rod is less likely to bend or the mounting hole to deform.
[0012] The present invention is further configured such that the reset mechanism includes a second connecting rod, the surface of which is fitted with a spring. The second connecting rod provides coaxial guidance for the spring, preventing lateral displacement or torsional deformation of the spring due to repeated opening and closing or vibration outdoors, ensuring that the spring always extends and contracts along the direction of force, maintaining a stable reset force. At the same time, the fixed connection between the second connecting rod and the support wall prevents the support point from loosening when the spring extends and contracts. Even with long-term repeated use outdoors, it can maintain stable reset performance, ensuring that the locking assembly can always remain pressed under the action of the spring, improving the continuous reliability of outdoor fixation.
[0013] The present invention is further configured such that a limiting plate is fixedly connected to one side of the spring, and a second anti-slip texture is provided at the bottom of the limiting plate. The limiting plate can adjust the extension and retraction stroke of the spring, and at the same time concentrate the elastic force of the spring onto the locking assembly.
[0014] The present invention is further provided with a pull rope on one side of the main frame, and a hook at the bottom of the pull rope. The hook can serve as an auxiliary fixing component and work with the pull rope to form a multi-directional pulling and fixing, thereby further improving the overall stability in strong wind outdoor scenarios.
[0015] The present invention has the following beneficial effects.
[0016] 1. This utility model adopts an integrally molded stainless steel structure. Stainless steel itself has excellent rust resistance and can resist the erosion of outdoor rainwater, salt and pollutants. The integral molding process avoids stress concentration areas such as welding joints, which greatly improves the overall rigidity of the structure. The outer surface of the main frame and the inner surface of the side arms are coated with a weather-resistant coating. The coating can isolate ultraviolet rays and oxygen from contact with the metal surface, further delaying corrosion and aging.
[0017] 2. This utility model uses a rubber plate to buffer and absorb residual vibration loads. At the same time, the rubber plate can increase the friction between the main frame and the mounting surface, avoiding overall displacement caused by outdoor vibration. In addition, it can also isolate the main frame from direct collision with the contact parts, preventing the contact parts from being scratched and reducing the noise generated by vibration, thus meeting the needs of outdoor quiet operation and effectively resisting the deformation of the device caused by transportation bumps.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please see Figure 1-5This utility model is a weather-resistant stainless steel eccentric buckle suitable for outdoor working conditions. It includes a main frame 1, a first connecting rod 2 is provided on one side of the inner cavity of the main frame 1, and a locking component 3 is provided on the surface of the first connecting rod 2. The two sides of the main frame 1 are vertical support walls, the inner surface of the support walls is arc-shaped and the edges are folded. A first hollow is opened on one side of the bottom of the main frame 1, and the first hollows are equally spaced. The whole is a one-piece molded stainless steel structure. A rubber plate 4 is fixedly connected to the other side of the bottom of the main frame 1. A reset mechanism 5 is provided on one side of the support wall. The outer surface of the main frame 1 and the inner surface of the side arm are coated with a weather-resistant coating.
[0027] Specifically: The main frame 1 has a trough-shaped structure and is integrally cast from stainless steel. Its left and right sides extend integrally to form support walls perpendicular to the bottom. A horizontally arranged first connecting rod 2 is fixed in the middle of the left inner wall of the main frame 1's inner cavity. Equally spaced first hollows are opened on one side of the bottom of the main frame 1. The hollows are rectangular with rounded edges, providing regular points for inserting the pull rope 11. The pull rope 11 can form a fixed structure with the locking component 3, improving the reliability of fixation in strong winds and vibrations outdoors. The rounded corner design prevents the rope from rubbing violently against the hollow edges, preventing wear and breakage of the pull rope 11. The size of the rubber plate 4 matches the bottom of the main frame 1, ensuring even distribution of vibration loads. The uniform buffering prevents uneven stress from causing buffer failure and maximizes the contact area with the mounting surface, increasing friction and further preventing overall frame displacement caused by outdoor vibration. It also isolates the metal from direct collision with the contact parts, reducing scratches and vibration noise. A second connecting rod 51 parallel to the first connecting rod 2 is welded to the inner middle of the right support wall. The outer surface of the main frame 1, the inner surfaces of the two support walls, and the exposed part of the first connecting rod 2 are all coated with a weather-resistant coating. The coating completely covers all metal surfaces, isolating rainwater, salt, and ultraviolet rays from direct contact with the metal surface, delaying corrosion and aging, avoiding local corrosion caused by partial coating omissions, ensuring consistent weather resistance of all parts, and adapting to different harsh outdoor working conditions.
[0028] The locking assembly 3 includes a stabilizing plate 31, one side of which is movably connected to the surface of the first connecting rod 2 via a bearing. A fixing tube 32 is sleeved on one side of the surface of the first connecting rod 2. A second hollow is opened at the top of the stabilizing plate 31, and the second hollows are equidistant. A pressure tongue 33 is provided on one side of the stabilizing plate 31, and the surface of the pressure tongue 33 is provided with a first anti-slip texture. Two mounting holes 6 are opened on one side of the top of the main frame 1. A mounting plate 7 is provided on the other side of the top of the main frame 1. Two threaded rods 8 are fixedly connected to one side of the mounting plate 7. One side of the threaded rod 8 passes through one side of the mounting hole 6 and is connected to a nut 9 by threads. The reset mechanism 5 includes a second connecting rod 51, and a spring 52 is sleeved on the surface of the second connecting rod 51. A limiting plate 10 is fixedly connected to one side of the spring 52. The bottom of the limiting plate 10 is provided with a second anti-slip texture. A pull rope 11 is provided on one side of the main frame 1, and a hook 12 is provided at the bottom of the pull rope 11.
[0029] Specifically: the second hollow section can serve as an auxiliary rope threading point, forming a multi-dimensional fixation with the first hollow section; the first anti-slip texture can form a surface contact anti-slip engagement with the second anti-slip texture, effectively resisting relative slippage caused by vibration and improving engagement reliability; the symmetrical mounting holes 6 can adapt to outdoor installation requirements, effectively limiting frame rotation and offset compared to existing single-hole installations; the two threaded rods 8 pass through the mounting holes 6 and are fixed by nuts 9, forming a symmetrical installation structure; during installation, the distance between the main frame 1 and the mounting base can be changed by adjusting the tightness of the nuts 9, thus adapting to mounting bases of different thicknesses; at the same time, the installation load can be evenly distributed to two stress points, avoiding stress concentration during single-rod installation; after long-term outdoor stress or vibration, the threaded rods 8 are less likely to bend or the mounting holes 6 to deform; the second connecting rod 51 The spring 52 is provided with a coaxial guide to prevent lateral displacement or torsional deformation caused by repeated opening and closing or vibration outdoors. This ensures that the spring 52 always extends and retracts in the direction of force, maintaining a stable restoring force. At the same time, the fixed connection between the second connecting rod 51 and the support wall prevents the support point from loosening when the spring 52 extends and retracts. Even with long-term repeated use outdoors, it can maintain stable restoring performance and ensure that the locking assembly 3 can always remain pressed under the action of the spring 52, improving the continuous reliability of outdoor fixation. The limiting plate 10 can adjust the extension and retraction stroke of the spring 52, and at the same time, it can concentrate the elastic force of the spring 52 onto the locking assembly 3. The hook 12 can serve as an auxiliary fixing component, working with the pull rope 11 to form a multi-directional traction fixation, further improving the overall stability in strong wind outdoor scenarios.
[0030] The working principle of this utility model is as follows: During the locking operation, the operator pulls the limiting plate 10, which no longer limits the pressure tongue 33. Then, the pressure tongue 33 is moved to adjust the angle of the stabilizing plate 31, causing the stabilizing plate 31 to rotate along the first connecting rod 2. The fixing tube 32 can make frictional contact with the stabilizing plate 31 to prevent the stabilizing plate 31 from rotating excessively due to inertia. When a certain angle is reached, the pull rope 11 is sequentially threaded into the first hollow, and then into the second hollow as needed, forming a multi-dimensional auxiliary fixing structure to prevent the frame from shifting due to strong winds or vibrations. Then, the stabilizing plate 31 is returned to its original position, the limiting plate 10 is released, and the limiting plate 10 resets under the action of the spring 52, allowing the limiting plate 10 to press the pressure tongue 33. Then, the installation and fixing of the main frame 1 begins. The two threaded rods 8 on the mounting plate 7 on the other side of the top of the main frame 1 are passed through the mounting holes 6. Then, the main frame 1 is clamped to the mounting base by the nuts 9. The bottom rubber plate 4 is in contact with the mounting surface, which not only buffers subsequent vibrations but also increases friction to prevent displacement. After installation, the pre-positioning is carried out. When outdoors, the weather-resistant coating on the outer surface of the main frame 1 and each metal component isolates rainwater, salt and ultraviolet corrosion. The one-piece molded stainless steel structure and the arc-shaped folded edge support wall resist vibration and wind load. The hollow rope and the locking component 3 form a double fixation to prevent the fixed parts from loosening. The rubber plate 4 buffers the vibration brought by transportation or wind and avoids direct metal collision and scratches on the mounting base.
[0031] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
