Description

Technical Field

[0001] This utility model relates to the field of photovoltaic clamping technology, and in particular to a self-locking fixing clamp for photovoltaic modules. Background Technology

[0002] In the installation of distributed photovoltaics on corrugated steel roofs, the first step is to select matching aluminum alloy clamps based on the specifications and models of the corrugated steel tiles. The aluminum alloy clamps for photovoltaic modules (hereinafter referred to as clamps) play an important role in the photovoltaic installation on corrugated steel roofs. When installing photovoltaic solar panels, the clamps are first installed on the corrugated steel tiles to fix the photovoltaic solar panels. When the construction workers install the clamps, the clamps are generally divided into two halves, each with a function. The two halves are combined together by screws. As the screws are tightened, the clamps are aligned with the corrugated steel tiles at an angle and hold them tightly. In this process, on-site installation is cumbersome, involves many fixing screws, and the screw installation efficiency is low. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a self-locking fixing clamp for photovoltaic modules. By setting up an opening and closing clamp and utilizing a combination of a clamping block and a self-locking screw to self-lock the clamp, the amount of screw fixing is reduced, thus saving installation costs.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] A self-locking fixing clamp for photovoltaic modules includes: a module to be installed, a clamping mechanism, and a pressing mechanism. The clamping mechanism includes a first clamping arm, a second clamping arm, and a clamping pin. The pressing mechanism includes a pressing block and a self-locking screw. The first clamping arm includes a first clamping upper arm, a first clamping joint, and a first clamping lower arm. The first clamping upper arm is connected to the first clamping lower arm through the first clamping joint. The second clamping arm includes a second clamping upper arm, a second clamping joint, and a second clamping lower arm. The second clamping upper arm is connected to the second clamping lower arm through the second clamping joint.

[0006] The clamping pin passes through the first clamping joint and the second clamping joint in succession, so that the first clamping arm and the second clamping arm form a hinge structure. The component to be installed and the clamping block are both provided with screw holes of the same size. The self-locking screw passes through the screw hole of the component to be installed and the screw hole of the clamping block in succession to connect the component to be installed and the clamping block. The clamping block is pressed between the first clamping upper arm and the second clamping upper arm, pushing the first clamping upper arm and the second clamping upper arm away from each other, and driving the first clamping lower arm and the second clamping lower arm to come closer to each other to clamp.

[0007] Preferably, the component to be installed is a photovoltaic module.

[0008] Preferably, the clamping mechanism further includes a spring washer and a flat washer, both of which have openings of the same size. The self-locking screw includes a head and a rod. The diameter of the head of the self-locking screw is larger than the diameter of the openings of the spring washer and the flat washer. The spring washer is located between the head of the self-locking screw and the photovoltaic module and is fitted onto the self-locking screw through the opening. The flat washer is located between the head of the self-locking screw and the spring washer and is fitted onto the self-locking screw through the opening.

[0009] Preferably, the first clamping arm further includes a first support portion, which is connected to the other end of the first clamping upper arm away from the first clamping joint. The second clamping arm further includes a second support portion, which is connected to the other end of the second clamping upper arm away from the second clamping joint.

[0013] Preferably, the clamping mechanism further includes a self-locking spring and a spring catch pin. The clamping pin includes a pin head and a pin rod connected to the pin head. The self-locking spring is fixedly disposed on the first clamping joint or the second clamping joint and sleeved on the tail end of the pin rod opposite to the pin head. When the clamping pin passes through the first clamping joint and the second clamping joint and presses the self-locking spring, it drives the spring catch pin to limit the self-locking spring and fix the self-locking spring.

[0014] Preferably, the clamping mechanism clamps onto the corrugated steel sheet. The first clamping arm further includes a first leg, which is located at the bottom of the first clamping lower arm that contacts the corrugated steel sheet and extends outward.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 2As shown, a self-locking fixing clamp for photovoltaic modules includes: a clamping mechanism and a pressing mechanism. The clamping mechanism includes a first clamping arm 2, a second clamping arm 3, and a clamping pin 4. The pressing mechanism includes a pressing block 6 and a self-locking screw 7. The first clamping arm 2 includes a first clamping upper arm 201, a first clamping joint 202, and a first clamping lower arm 203. The first clamping upper arm 201 is connected to the first clamping lower arm 203 through the first clamping joint 202. The second clamping arm 3 includes a second clamping upper arm 301, a second clamping joint 302, and a second clamping lower arm 303. The second clamping upper arm 301 is connected to the second clamping lower arm 303 through the second clamping joint 302.

[0024] The clamp pin 4 passes through the first clamping joint 202 and the second clamping joint 302 in succession, so that the first clamping arm 2 and the second clamping arm 3 form a hinge structure. The component to be installed and the clamping block 6 are both provided with screw holes of the same size. The self-locking screw 7 passes through the screw hole of the component to be installed and the screw hole of the clamping block 6 in succession to connect the component to be installed and the clamping block 6. The clamping block 6 is pressed between the first clamping upper arm 201 and the second clamping upper arm 301, pushing the first clamping upper arm 201 and the second clamping upper arm 301 away from each other, and driving the first clamping lower arm 203 and the second clamping lower arm 303 to come closer to each other to clamp.

[0025] The first clamping joint 202 and the second clamping joint 302 are annular structures, respectively connecting the upper clamping arm and the lower clamping arm. The first clamping joint 202 and the second clamping joint 302 are arranged front and back, on the same horizontal line. The clamping pin 4 passes through the annular structure of the first clamping joint 202 and the second clamping joint 302, connecting the first clamping arm 2 and the second clamping arm 3. After the two form a hinge structure, the clamping block 6 is inserted between the first clamping upper arm 201 and the second clamping upper arm 301 and is clamped on the clamping joint. The clamping block 6 is also connected to the component to be installed through the self-locking screw 7. Therefore, when the clamping mechanism and the component to be installed are set up, the whole formed by the component to be installed and the clamping block 6 will push the clamping mechanism downward under the action of gravity, so that the first clamping upper arm 201 and the second clamping upper arm 301 are kept in the open state, and the lower clamping arm 203 is driven to move inward to clamp.

[0026] In addition, the clamping mechanism in this embodiment is used to clamp the color steel tile 1. The shapes of the first clamping lower arm 203 and the second clamping upper arm 301 are both in line with the shape of the color steel tile 1 to ensure that the color steel tile 1 can be tightly clamped.

[0027] In an optional embodiment, the component to be installed is a photovoltaic module 10.

[0028] In an optional embodiment, the clamping mechanism further includes a spring pad 8 and a flat pad 9, both of which have openings of the same size. The self-locking screw 7 includes a head and a rod. The diameter of the head of the self-locking screw 7 is larger than the diameter of the openings of the spring pad 8 and the flat pad 9. The spring pad 8 is located between the head of the self-locking screw 7 and the photovoltaic module 10 and is fitted onto the self-locking screw 7 through the opening. The flat pad 9 is located between the head of the self-locking screw 7 and the spring pad 8 and is fitted onto the self-locking screw 7 through the opening.

[0029] By setting spring washer 8 and flat washer 9, the stability of self-locking screw 7 is enhanced. Spring washer 8 provides continuous axial preload by utilizing its own elastic deformation, while flat washer 9 is located below spring washer 8, increasing the force-bearing area and preventing the nut or screw from damaging the surface of the color steel tile. At the same time, it provides a smooth surface to avoid uneven friction caused by direct metal-to-metal contact.

[0030] In an optional embodiment, the first clamping arm 2 further includes a first support portion 204, which is connected to the other end of the first clamping upper arm 201 away from the first clamping joint 202. The second clamping arm 3 further includes a second support portion 304, which is connected to the other end of the second clamping upper arm 301 away from the second clamping joint 302. The plane formed by the first support portion 204 and the second support portion 304 is parallel to the plane where the photovoltaic module 10 is located.

[0031] By setting horizontally parallel support parts in the first and second support arms, the contact area between the clamping mechanism and the photovoltaic module 10 is increased, the stability of the clamping mechanism is enhanced, and the force is balanced.

[0032] In an optional embodiment, the side of the clamping block 6 closest to the first clamping joint 202 is the bottom surface of the clamping block 6, and the side of the clamping block 6 opposite to the bottom surface is the top surface of the clamping block 6, wherein the bottom surface area of ​​the clamping block 6 is larger than the top surface area.

[0033] Specifically, the clamping block 6 has a trapezoidal structure. When subjected to force, it will generate a force decomposition effect perpendicular to the contact surface, causing the clamping block 6 to automatically conform to the clamping mechanism, preventing slippage or displacement, and increasing the contact area with the clamping mechanism to enhance stability.

[0034] In an optional embodiment, there is a gap between the first support portion 204 and the second support portion 304, the width of which is greater than the width of the top surface of the clamping block 6.

[0035] like Figure 1 As shown, the contact portions of the first support portion 204 and the second support portion 304 with the clamping block 6 are parallel to the side of the clamping block 6, forming a cross-section that clamps the clamping block 6, thereby limiting the clamping block 6 so that it will not loosen or come out.

[0036] In an optional embodiment, the surfaces of the first support portion 204 and the second support portion 304 that contact the photovoltaic module 10 are provided with a first anti-slip portion.

[0037] The first anti-slip part can be made of anti-slip material or a rough surface that increases friction to increase the friction between the support and the photovoltaic module 10, counteract the shaking of the photovoltaic module 10, and prevent the photovoltaic module 10 from tilting or loosening due to natural external forces, causing the clamp to lose balance.

[0038] like Figure 3 As shown, in an optional embodiment, the clamping mechanism further includes a self-locking spring 5 and a spring latch 11. The clamping pin 4 includes a pin head and a pin rod connected to the pin head. The self-locking spring 5 is fixedly disposed on the first clamping joint 202 or the second clamping joint 302 and sleeved on the tail end of the pin rod opposite to the pin head. When the clamping pin 4 passes through the first clamping joint 202 and the second clamping joint 302 and presses the self-locking spring 5, it drives the spring latch 11 to limit the self-locking spring 5 and fix the self-locking spring 5.

[0039] By incorporating a self-locking spring 5 with a locking pin, the clamp pin 4 can be easily installed and secured. The clamp pin 4 only needs to be pushed into the clamping joint to move the self-locking spring 5, thereby fixing the self-locking spring 5 with the spring locking pin 11, thus limiting the clamp pin 4. Specifically, the diameter of the tail of the clamp pin 4 is slightly larger than the diameter of the self-locking spring 5. Therefore, when the self-locking spring 5 is tightly pressed and fixed under the action of the spring locking pin 11, it can limit the clamp pin 4 and prevent it from slipping out.

[0040] In an optional embodiment, the clamping mechanism clamps onto the corrugated steel sheet 1. The first clamping arm 2 further includes a first leg 205, which is located at the bottom of the first clamping lower arm 203 in contact with the corrugated steel sheet 1 and extends outward. The second clamping arm 3 further includes a second leg 305, which is located at the bottom of the second clamping lower arm 303 in contact with the corrugated steel sheet 1 and extends outward. Both the first leg 205 and the second leg 305 are parallel to the plane of the corrugated steel sheet 1.

[0041] By setting the first support leg 205 and the second support leg 305, the contact area with the color steel tile 1 is increased, so that the clamping mechanism forms a stable support structure, avoiding shaking under the action of external force and affecting the stability of the clamping mechanism.

[0042] In an optional embodiment, the surfaces of the first clamping lower arm 203 and the second clamping lower arm 303 that contact the color steel tile 1 are both provided with a second anti-slip part.

[0043] The stability of the clamping mechanism is increased by setting a second anti-slip part, which can be an anti-slip material or a rough surface that can increase friction.

[0044] In an optional embodiment, the second anti-slip portion is serrated.

[0045] The serrated design increases the friction between the corrugated steel sheet 1 and the first clamping lower arm 203 and the second clamping lower arm 303, ensuring that they do not loosen or wobble after clamping the corrugated steel sheet 1.
