When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0036] Example 1

[0037] Reference Figures 1 to 9 , which is the first embodiment of the present invention, provides a quick-disassembly and assembly flexible photovoltaic panel anti-detachment fixing frame, which includes a receiving unit 100, including a mounting plate 101 and a fixing member 102 symmetrically fixed on the top thereof, and a lifting member 103 is also symmetrically installed in the mounting plate 101.

[0038] The fixing unit 200 includes a locking sleeve 201 and a locking member 202 connected to the side wall thereof. The locking sleeve 201 is symmetrically fixed at both ends of the mounting plate 101 and movably sleeved outside the flexible steel cable.

[0039] The mounting plate 101 includes a symmetrically arranged main plate body 101a and a sliding sleeve 101b and a connecting side plate 101c symmetrically fixed to one end thereof in sequence. The ends of the main plate bodies 101a on both sides that are close to each other are fixed to each other, and the locking sliding sleeves 201 are symmetrically fixed to the ends of the main plate bodies 101a on both sides that are away from each other.

[0040] The locking sleeve 201 comprises an external locking sleeve 201a and an internal jacket 201b. The external locking sleeve 201a is movably mounted outside the sliding sleeve 101b, and the internal jacket 201b is movably mounted inside the sliding sleeve 101b.

[0041] The receiving unit 100 is made of a metal material with high hardness and light weight as a whole. In this embodiment, an aluminum alloy material is preferably used, and the exterior is subjected to anti-corrosion treatment.

[0042] The main boards 101a on both sides have the same structure, and the side wall of one end of the sliding sleeve 101b is respectively fixed to the main board 101a and the connecting side board 101c through a stabilizing connecting plate 101d; the sliding sleeve 101b is symmetrically arranged on both sides of the stabilizing connecting plate 101d.

[0043] Furthermore, each group of mounting plates 101 is preferably provided with two main board bodies 101a, which are symmetrical on the left and right, and the sliding sleeves 101b are symmetrically installed at one end of the main board body 101a away from each other. Two sliding sleeves 101b are preferably connected to each main board body 101a, and the two sliding sleeves 101b overlap axially, and the flexible steel cable passes through the inside of the sliding sleeve 101b.

[0044] A connecting ring 101b-1 is fixed to the outer wall of one end of the sliding sleeve 101b away from the stabilizing connecting plate 101d, and an external thread W1 is provided on the outer wall of the connecting ring 101b-1; the sliding sleeve 101b is provided with a pre-tightening tapered hole 101b-2, a stabilizing sliding hole 101b-3, a reset sliding hole 101b-4 and a threading hole 101b-5 in sequence from the connecting ring 101b-1 to the stabilizing connecting plate 101d; the threading holes 101b-5 provided in the sliding sleeves 101b on both sides are connected to each other.

[0045] During use, the number of mounting plates 101 to be used is determined according to the number of photovoltaic panels to be installed, and the flexible steel cable is passed through the sliding sleeve 101b, and then the two ends of the flexible steel cable are fixed to keep it in a straight and stable state.

[0046] Furthermore, after sliding the two adjacent mounting plates 101 left and right to a distance approximately equal to the width of the photovoltaic panel, the locking sleeve 201 is further rotated so that the internally built-in clamping sleeve 201b clamps the steel cable. The locking member 202 will automatically limit the lateral displacement of the locking sleeve 201 to prevent it from loosening, thereby making it impossible to fix the mounting plate 101 and causing the photovoltaic panel to fall.

[0047] Furthermore, after the photovoltaic panel is placed on the mounting plate 101, the lifting member 103 supports the metal bracket position at the edge of the photovoltaic panel from below to prevent the photovoltaic panel from being too large and unable to be installed.

[0048] Furthermore, after the mounting plate 101 is completely and stably locked, the fixing member 102 is adjusted to clamp the photovoltaic panel frame from top to bottom, and the mounting plate 101 and the lifting member 103 are cooperated to realize bidirectional clamping and fixing of the photovoltaic panel, thereby ensuring the installation stability of the photovoltaic panel.

[0049] Example 2

[0050] Reference Figures 1 to 10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that an internal thread W2 is provided on the inner wall of the external locking sleeve 201a, and the internal thread W2 is threadedly connected to the external thread W1. By rotating the external locking sleeve 201a, it can move laterally outside the sliding sleeve 101b.

[0051] The openings at both ends of the external locking sleeve 201a are respectively detachably fixed with a first sealing ring 201a-1 and a second sealing ring 201a-2. The middle parts of the first sealing ring 201a-1 and the second sealing ring 201a-2 are respectively provided with a wire through hole 201a-1a and a sealing hole 201a-2a. The sliding sleeve 101b and the steel cable are respectively slidably inserted into the sealing hole 201a-2a and the wire through hole 201a-1a.

[0052] The inner diameter of the wire through hole 201a-1a is slightly larger than the outer diameter of the installed steel cable, and the inner diameter of the sealing hole 201a-2a is the same as the outer diameter of the sliding sleeve 101b, which can ensure that the external locking sleeve 201a slides smoothly outside the sliding sleeve 101b to prevent shaking.

[0053] The built-in jacket 201b includes an abutment ring 201b-1 and an elastic cone block 201b-2, a threading sleeve 201b-3 and a spring ring 201b-4 which are fixed to the ends of the abutment ring 201b-1 in sequence.

[0054] The abutment ring 201b-1 movably abuts against the end of the connecting ring 101b-1, the outer wall of the elastic cone block 201b-2 slides in contact with the inner wall of the pre-tightening cone hole 101b-2, the threading sleeve 201b-3 is slidably inserted into the stabilizing slide hole 101b-3, the spring ring 201b-4 is slidably placed in the reset slide hole 101b-4, and a first spring T1 is fixed between the spring ring 201b-4 and the end of the reset slide hole 101b-4.

[0055] The circumferential outer walls of the elastic cone block 201b-2 and the threading sleeve 201b-3 are provided with at least one set of clamping and shrinking holes 201b-2a, and the clamping and shrinking holes 201b-2a divide the elastic cone block 201b-2 to form a conical angle block 201b-2b, in which a clamping ball 201b-2c is rollingly installed.

[0056] It should be noted that the length of the elastic cone block 201b-2 is greater than the length of the preload cone hole 101b-2, and in the natural state of the elastic cone block 201b-2, the inner diameter of the cone mouth is greater than the opening with the preload cone hole 101b-2.

[0057] During use, as the external locking sleeve 201a rotates and moves, the first sealing ring 201a-1 will squeeze the abutment ring 201b-1, driving it to move toward the inside of the sliding sleeve 101b, and the first spring T1 will shrink due to the squeezing force. During this process, the outer surface of the tapered angle block 201b-2b gradually slides into contact with the oblique inner wall of the pre-tightening tapered hole 101b-2. As the tapered angle block 201b-2b is gradually pushed inward, it shrinks and clamps toward the center.

[0058] Furthermore, the steel cable passes through the middle of the built-in jacket 201b, and as the tapered angle block 201b-2b is tightened toward the middle, the clamping ball 201b-2c cooperates with the inner wall of the tapered angle block 201b-2b to clamp the steel cable, wherein the clamping ball 201b-2c is made of wear-resistant rubber, and the built-in jacket 201b is made of polyurethane material with higher hardness, which can increase friction.

[0059] The function of the clamping shrinkage hole 201b-2a is to ensure that the tapered angle block 201b-2b and the threading sleeve 201b-3 can deform normally, reduce the interaction force, and prevent breakage.

[0060] A vertical plate 101a-1 is vertically fixed to the top of one end of the main board body 101a close to the sliding sleeve 101b, and a center stopper 101a-2 is also fixed to the middle of the side of the vertical plate 101a-1 away from the sliding sleeve 101b. The center stopper 101a-2 is also fixed to the top of the main board body 101a, and a placement groove 101a-3 is formed between the vertical plate 101a-1, the center stopper 101a-2 and the main board body 101a.

[0061] During use, the four corners of the photovoltaic panel can be respectively placed in the placement groove 101a-3, which can initially stabilize the photovoltaic panel.

[0062] A sliding groove 101a-2a is provided in the central stopper 101a-2, and sliding slots 101a-2b are provided on both side walls thereof. Connecting blocks 101a-2c are symmetrically fixed at both ends of the bottom of the main board body 101a.

[0063] A width-adjusting threaded rod 101e is rotatably connected between the symmetrical main bodies 101a. The width-adjusting threaded rod 101e is threadedly inserted into the connecting blocks 101a-2c on both sides, a rotating sleeve 101e-1 is fixed in the middle, and anti-drop caps 101e-2 are fixed at both ends.

[0064] During use, photovoltaic panels of different widths can be adapted by adjusting the distance between the mounting plates 101, and photovoltaic panels of different lengths can be installed by rotating the sleeve 101e-1. The main boards 101a on both sides can extend to both sides or shrink to the middle under the action of threads to adapt to photovoltaic panels of different sizes.

[0065] A sliding column 101a-4 is fixed to the inner wall of the sliding groove 101a-2a close to the sliding sleeve 101b, and the second spring T2 and the third spring T3 are connected to the outer sleeve of the sliding column 101a-4.

[0066] The fixing member 102 includes a main pressure plate 102a, one side of which is connected to a hinge shaft 102b, and the other side of the main pressure plate 102a is also connected to an auxiliary pressure plate 102c, both ends of the hinge shaft 102b are rotatably sleeved with hinge rods 102d, the other end of the hinge rod 102d is also rotatably sleeved with the sliding column 101a-4, and two groups of hinge rods 102d are arranged; both ends of the third spring T3 are respectively fixed to the side walls of the two groups of hinge rods 102d sleeved on the sliding column 101a-4.

[0067] A threaded sleeve 102e is fixed on the top of the main pressure plate 102a, and adjusting threaded rods 102f are inserted into the inner threads of the threaded sleeves 102e on both sides.

[0068] During use, if one wants to clamp the photovoltaic panel from top to bottom, one only needs to rotate the adjusting threaded rod 102f to increase the distance between the main pressure plates 102a on both sides, and due to the limitation of the adjusting threaded rod 102f, the main pressure plates 102a are always in a horizontal position.

[0069] Furthermore, as the distance between the main pressing plates 102a gradually increases, the height of the main pressing plates 102a decreases, and finally squeezes above the edge of the photovoltaic panel, and finally cooperates with the bottom of the groove 101a-3 to fix the photovoltaic panel.

[0070] The lifting member 103 includes an inserting slider 103a and lifting plates 103b symmetrically fixed on both sides of the bottom end thereof, and an adapting pressing plate 103c is fixed on the top of the lifting plate 103b via a fourth spring T4.

[0071] Under the elastic support of the fourth spring T4, the adaptor pressure plate 103c can always be supported at the bottom of the four corners of the photovoltaic panel. If the photovoltaic panel vibrates, the lifting plate 103b can always provide stable support to the photovoltaic panel.

[0072] A stabilizing plate 103a-1 is fixed on the top of the plug-in slider 103a, a sliding hole 103a-2 is opened inside the plug-in slider 103a, the plug-in slider 103a and the slide column 101a-4 are slidably plugged into the slide groove 101a-2a and the sliding hole 103a-2 respectively, and the side wall of the plug-in slider 103a is also fixed to the second spring T2.

[0073] During use, if the distance between the main pressure plates 102a is to be adjusted for photovoltaic panels of different sizes, when the size of the photovoltaic panel to be installed is small, rotate the width-adjusting threaded rod 101e to control the main board bodies 101a on both sides to converge toward the center. During this process, the length of the main pressure plate 102a cannot be changed, and the main pressure plate 102a will push the plug-in slider 103a through two sets of hinge rods 102d and the third spring T3.

[0074] At this time, the distance between the main bodies 101a gradually decreases, and the distance between the plug-in sliders 103a remains unchanged. The plug-in sliders 103a slide in the slide groove 101a-2a and squeeze the second spring T2. At this time, the side walls of the plug-in sliders 103a on both sides with the sliding holes 103a-2 are always respectively in contact with the hinge shaft 102b and the second spring T2, and the lifting member 103 and the main pressure plate 102a are relatively displaced, and the second spring T2 contracts until the main pressure plate 102a is controlled by the width-adjusting threaded rod 101e to move to the required size position, thereby clamping and fixing the small-sized photovoltaic panel.

[0075] The remaining structures are the same as those of Example 1.

[0076] Example 3

[0077] Reference Figures 1 to 12 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the locking member 202 includes an anti-loosening sliding sleeve 202a and a control card plate 202b, the anti-loosening sliding sleeve 202a is fixedly clamped on the outside of the external locking sleeve 201a, and the control card plate 202b is movably installed on the side wall of the connecting side plate 101c.

[0078] The anti-loosening sliding sleeve 202a includes a symmetrically arranged first snap ring 202a-1, a second snap ring 202a-2 and a lateral tooth plate 202a-3 connecting the side walls of the first snap ring 202a-1 and the second snap ring 202a-2, and the side wall of the lateral tooth plate 202a-3 is provided with an oblique tooth groove 203a-3a.

[0079] The lateral tooth plate 202a-3 is fixedly connected to the edge side walls of the first clamping ring 202a-1 and the second clamping ring 202a-2, so as to be close to the connecting side plate 101c.

[0080] The inner end surfaces of the first clamping ring 202a-1 and the second clamping ring 202a-2 are fixedly abutted against the two ends of the external locking sleeve 201a. During use, the anti-loosening sliding sleeve 202a can move along with the external locking sleeve 201a.

[0081] Horizontal support plates 101c-1 are symmetrically connected to the middle of the top and bottom side walls of the connecting side plate 101c, and the control card plate 202b is slidably inserted between the horizontal support plates 101c-1. When the external locking sleeve 201a is at the outermost side, the end of the control card plate 202b close to the stabilizing connecting plate 101d is still inserted between the horizontal support plates 101c-1 to prevent the anti-loosening sliding sleeve 202a from rotating with the external locking sleeve 201a.

[0082] A control socket 101c-2 is provided in the middle of the connecting side plate 101c, and reset adjustment holes 101c-3 are symmetrically provided in the connecting side plates 101c at both ends of the control socket 101c-2. A support column 101c-3a is horizontally connected in the reset adjustment hole 101c-3, and a fifth spring T5 is connected to the outer sleeve of the support column 101c-3a.

[0083] Plug-in boards 202b-1 are fixed at both ends of the control card board 202b. The control card board 202b and the plug-in board 202b-1 are slidably plugged into the control socket 101c-2 and the reset adjustment hole 101c-3 respectively. The plug-in board 202b-1 is slidably sleeved on the outside of the support column 101c-3a, and its side away from the anti-loosening sliding sleeve 202a is fixed to the fifth spring T5.
