Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic modules, in particular to a frame structure of a photovoltaic module and a spliced outer frame. BACKGROUND

[0002] Photovoltaic power generation is a technology that converts light energy into electricity by using the photovoltaic effect of the semiconductor interface. It mainly consists of solar panels (modules), controllers and inverters, and the main components are composed of electronic components. Solar cells are connected in series and then encapsulated to form a large area of solar cell modules, which, together with power controllers and other components, form a photovoltaic power generation device. The solar panels (modules) need to be protected by an outer frame, otherwise the panels are easily damaged by the external environment. At the same time, the outer frame structure around the photovoltaic panel can limit and fix multiple panels, facilitating the combination of photovoltaic panels.

[0003] However, the existing photovoltaic panel outer frame assembly is generally one-piece, which is fixed by sleeving the photovoltaic panel. However, the one-piece outer frame is difficult to adapt to different specifications of the photovoltaic panel, especially when the thickness of the photovoltaic panel is different, the outer frame assembly needs to be produced additionally, and the application range is small during use. Secondly, some spliced photovoltaic panel outer frame assemblies are assembled by multiple fixed screws, which cannot be quickly and conveniently assembled according to the specifications of the photovoltaic panel. It is time-consuming and laborious to assemble. At the same time, the structure of the outer frame assembly is relatively thin, and it is difficult to achieve comprehensive protection of the edge of the photovoltaic panel after sleeving. CONTENT OF THE INVENTION

[0004] In order to solve at least one of the above technical problems, the present application provides a frame structure of a photovoltaic module and a spliced outer frame. The thickness of the inner frame can be adjusted by the adjusting mechanism, which can adapt to photovoltaic panels of different thicknesses. Especially when the photovoltaic panels of different thicknesses are assembled, the adjusting mechanism can be self-adapted to expand and contract, which has a wide application range and a simple installation method.

[0005] Therefore, in a first aspect, the present application provides a frame structure of a photovoltaic module, comprising: an inner frame, an outer frame and an inner protective layer, the outer frame covering the inner frame, and the inner protective layer being arranged between the outer frame and the inner frame; wherein the inner frame comprises a clamping mechanism and an adjusting mechanism, and the adjusting mechanism is fixed to the clamping mechanism; the clamping mechanism comprises a left clamping part, a right clamping part and an elastic member connecting the left clamping part and the right clamping part, which are symmetrically arranged; the adjusting mechanism comprises an adjusting seat, a left limiting frame and a right limiting frame, the left limiting frame is connected to the left clamping part, and the right limiting frame is connected to the right clamping part; the left limiting frame and the right limiting frame are arranged on both sides of the adjusting seat, and at least one of the left limiting frame and the right limiting frame is movably connected to the adjusting seat in the left-right direction.

[0006] The inner frame is used for clamping the photovoltaic panel, and the outer frame cooperates with the inner frame to clamp the photovoltaic panel and fixes and protects the inner frame. The inner frame is provided with a clamping mechanism for clamping the photovoltaic panel, and the size of the inner space of the clamping mechanism is adjusted through an adjusting mechanism, so that the clamping mechanism can clamp photovoltaic panels of different thicknesses. The two ends of the adjusting seat are provided with cavities, and the left and right limiting frames are inserted into the cavities and are in a pull-out type movable linkage with the adjusting seat. The distance between the left and right limiting frames can be adjusted through the pull-out type connection, so that the photovoltaic panels of different thicknesses can be clamped by adjusting the distance. The present embodiment can meet the fixing requirements of photovoltaic panels of various specifications through a set of frame structure, and can be mass-produced to reduce manufacturing costs. The double-frame structure can also improve the overall structural strength of the frame and provide stronger protection for the photovoltaic panel.

[0007] In combination with the above frame structure, the left limiting frame and the right limiting frame are fixed at the end of the clamping mechanism.

[0008] In the present embodiment, the left limiting frame and the right limiting frame are fixedly arranged at the end of the clamping mechanism, which facilitates the operation of workers and enables the clamping of photovoltaic panels to be completed without the aid of tools, thus being simple to operate and improving work efficiency.

[0009] In combination with the above frame structure, the left clamping part or the right clamping part is arranged in a U shape and includes an inner frame side plate and an inner frame upright plate, and the inner frame side plate and the inner frame upright plate are arranged perpendicularly along the edges thereof. The two ends of the elastic member are fixedly connected with the inner frame side plates of the left clamping part and the right clamping part, respectively.

[0010] In the present embodiment, the clamping mechanism is composed of a left clamping part, a right clamping part, and an elastic member connecting the left and right clamping parts. The distance between the left and right clamping parts is the thickness of the clamping photovoltaic panel. The U-shaped clamping mechanism includes a left clamping part and a right clamping part, and the left and right clamping parts are symmetrically arranged. When clamping photovoltaic panels of different thicknesses, the distance between the left and right clamping parts can be adjusted by the extension and contraction of the elastic member to meet the clamping requirements of photovoltaic panels of different thicknesses.

[0011] In combination with the above frame structure, the left limiting frame or the right limiting frame includes a limiting part in pull-out type connection with the adjusting seat, and a fixed part with one end fixed to the limiting part and the other end fixed to the clamping mechanism.

[0012] In the present implementation, the left limiting frame and the right limiting frame have the same structure, and each includes a limiting portion and a fixed portion. The fixed portion is fixedly connected with the limiting portion. A part of the limiting portion is inserted into the adjusting seat and is movably connected with the adjusting seat in a pulling manner. One end of the fixed portion is fixed to the limiting portion outside the adjusting seat, and the other end is fixedly connected with the clamping mechanism. The left limiting frame or the right limiting frame is fixed with the clamping mechanism through the fixed portion and is movably connected with the adjusting seat in a pulling manner through the limiting portion. The clamping thickness of the adjustable clamping mechanism can be adjusted to meet the clamping needs of photovoltaic panels of different thicknesses.

[0013] In combination with the above-described frame structure, a through hole is formed in the inner frame vertical plate, the limiting portion is a bent piece, one end of the limiting portion is located in the through hole, and the other end is movably connected with the adjusting seat in a pulling manner; and the fixed portion is a bent piece, and the other end of the fixed portion is fixedly connected with the inner frame vertical plate.

[0014] In the present implementation, the left and right clamping portions are each composed of an inner frame side plate and an inner frame vertical plate. The inner frame side plate and the inner frame vertical plate are arranged perpendicularly. Since the left and right clamping portions are symmetrically arranged, the inner frame vertical plates of the left and right clamping portions are parallel to each other, and the inner frame side plates of the left and right clamping portions are located in the same plane. The through hole formed in the inner frame vertical plate provides a moving space for the limiting portion. During the pulling action of the limiting portion, one end of the limiting portion can pass through the through hole, so that the overall movement of the limiting portion is not restricted. One end of the fixed portion is fixedly connected with the part of the limiting portion outside the adjusting seat and the through hole, and the other end is fixed on the inner frame vertical plate, thereby providing support for the limiting portion and the adjusting seat. Therefore, the left limiting frame or the right limiting frame is fixed on the left or right clamping portion, respectively, and moves together with the left or right clamping portion, respectively, thereby achieving limiting control of the clamping mechanism.

[0015] In combination with the above-described frame structure, the elastic piece is arranged in a U shape along the outer surface of the inner frame side plate.

[0016] In the present implementation, the two ends of the elastic piece are fixed on the outer surfaces of the inner frame side plates of the left and right clamping portions, respectively, and are arranged along the outer surfaces of the inner frame side plates. The elastic piece has the same shape as the left and right clamping portions, facilitating assembly and improving the stability of the connection with the left and right clamping portions.

[0017] In combination with the above-described frame structure, the outer frame includes a left frame and a right frame. The left frame abuts against the left limiting frame, and the right frame abuts against the right limiting frame. The end portion of the left frame has a hollow structure, and the end portion of the right frame is located in the hollow structure and is movably connected with the left frame in a pulling manner.

[0018] The present implementation adopts the left frame and the right frame that are movably connected in a pulling manner to form the outer frame, which can cooperate with the adjusting mechanism in the inner frame to adjust the space of the inner frame, thereby meeting the installation needs of photovoltaic panels of different thicknesses. When the left frame and the right frame move, the right frame can slide in the left frame, thereby saving assembly space.

[0019] In combination with the above-described frame structure, the left frame and the right frame are provided with clamping strips, and the inner frame vertical plate is provided with clamping grooves.

[0020] In the present implementation, the clamping strip provided on the outer frame is clamped with the clamping groove provided on the inner frame, which can quickly align and install the outer frame and the inner frame, and can avoid relative displacement between the inner frame and the outer frame, thereby improving the stability of the frame structure.

[0021] In combination with the above-described frame structure, the inner protective layer is elastic, and the inner protective layer is fixedly connected with the left frame and the right frame.

[0022] In the present implementation, the inner protective layer provided between the inner frame and the outer frame is made of elastic material, which can buffer the movement of the inner frame and the outer frame, eliminate stress, protect the photovoltaic panel, and prevent damage.

[0023] In a second aspect, the application provides a spliced outer frame, which comprises two frame structures as described above and is fixed by a connecting piece.

[0024] In the present implementation, the spliced outer frame uses two frame structures to fix the photovoltaic panel. Since the frame structure is U-shaped, the two frame structures can be wrapped around the edges of the rectangular photovoltaic panel to protect the photovoltaic panel. The spliced outer frame uses a frame structure with adjustable clamping thickness to fix photovoltaic panels of various specifications. In particular, the spliced outer frame can fix photovoltaic panels of different thicknesses by clamping the photovoltaic panels of different thicknesses with the two frame structures and then fixing the two frame structures. Therefore, the implementation can meet various splicing requirements, is flexible and convenient to use, and has a wider range of applications.

[0025] The frame structure and the spliced outer frame of the photovoltaic module provided by the application have at least the following beneficial effects compared with the prior art: the frame structure uses a combined inner frame and outer frame to fix the photovoltaic panel, the inner frame is used to clamp the photovoltaic panel, the outer frame cooperates with the inner frame to clamp the photovoltaic panel, and the outer frame has a fixing and protection effect on the inner frame. The inner frame is provided with an adjusting mechanism to adjust the size of the inner space of the clamping mechanism, so that the clamping mechanism can clamp photovoltaic panels of different thicknesses. The present implementation can meet the fixing requirements of photovoltaic panels of various specifications by using a set of frame structure, which can be mass-produced to reduce manufacturing costs. The double-frame structure can also improve the overall structural strength of the frame, provide stronger protection for the photovoltaic panel, and facilitate installation and maintenance.

[0026] Other features and advantages of the present application will be described in detail in the following specific embodiment part. BRIEF DESCRIPTION OF DRAWINGS

[0038] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0040] In the description of the present application, it should be noted that unless specifically defined and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or interference connection or integral connection; for those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0041] In the description of the present application, specific features, structures, materials or characteristics can be combined in any one or more embodiments in a suitable manner.

[0042] The outer frame of photovoltaic panel is an important part of solar photovoltaic module, which mainly plays a role in packaging cell sheet, glass, back plate and other materials, enhancing the strength of the module, facilitating transportation, installation and protection of photovoltaic module. Photovoltaic frame needs to have strong bearing capacity and corrosion resistance, and its performance directly affects the installation and service life of the battery module. According to the material, it can be divided into: aluminum alloy frame, steel frame and composite material frame. The design of these frame structures needs to meet certain performance requirements, and can prevent back glass from bursting and prevent the deformation of the module, so as to ensure the stability of the module output power and have high power generation capacity.

[0043] The existing photovoltaic panel outer frame assembly is generally one-piece, which is sleeved and fixed to the photovoltaic panel. However, the one-piece outer frame is difficult to adapt to the assembly of photovoltaic panels of different specifications, especially when facing photovoltaic panels of different thickness specifications, only the outer frame assembly can be produced additionally, and the application range is small during use. Secondly, some existing spliced photovoltaic panel outer frame assemblies are spliced and assembled by multiple fixed screws, which cannot be quickly and conveniently assembled according to the specifications of the photovoltaic panel. It is time-consuming and laborious to assemble the operation. At the same time, the outer frame assembly structure is relatively thin, and after the sleeve assembly with the edge position of the photovoltaic panel, it is difficult to achieve comprehensive protection of the edge position of the photovoltaic panel.

[0044] Therefore, the present application provides a frame structure of a photovoltaic module to solve the technical problems of small application range of the frame of the photovoltaic module in the prior art, which cannot meet the installation needs of photovoltaic panels of different specifications, and low strength and poor protection of the frame structure.

[0045] Figure 1 A frame structure of a photovoltaic module provided by the present application is shown in the figure. Figure 2 A disassembly structure diagram of an inner frame and an inner protection layer provided by the present application is shown in the figure. Figure 1 And 2As shown, the frame structure comprises: an inner frame 100, an outer frame 200 and an inner protective layer 300, the outer frame 200 covers the inner frame 100, and the inner protective layer 300 is arranged between the outer frame 200 and the inner frame 100; wherein the inner frame 100 comprises a clamping mechanism 120 and an adjusting mechanism 110, and the adjusting mechanism 110 is fixed to the clamping mechanism 120; the clamping mechanism 120 comprises a left clamping part 121, a right clamping part 122 and an elastic piece 123 connecting the left clamping part 121 and the right clamping part 122; the adjusting mechanism 110 comprises an adjusting seat 111, a left limiting frame 112 and a right limiting frame 113, the left limiting frame 112 is connected to the left clamping part 121, and the right limiting frame 113 is connected to the right clamping part 122; the left limiting frame 112 and the right limiting frame 113 are respectively arranged on both sides of the adjusting seat 111, and at least one of the left limiting frame 112 and the right limiting frame 113 is movably connected to the adjusting seat along the left-right direction.

[0046] The inner frame 100 is used for fixing the photovoltaic panel. During installation, the inner frame 100 clamps the edge of the photovoltaic panel and gradually applies clamping force to the edge of the photovoltaic panel until the photovoltaic panel is fixed. The outer frame 200 is arranged outside the inner frame 100 and covers the inner frame 100. The side edges of the outer frame 200 are in contact with the inner frame 100 to form a rigid connection, thereby strengthening and protecting the inner frame 100. The inner protective layer 300 is arranged between the outer frame 200 and the inner frame 100 and serves as a buffer layer to eliminate damage to the photovoltaic panel caused by external forces. In an embodiment, the inner protective layer 300 can be made of elastic material and has certain elasticity, such as sponge, foam plastic, etc.

[0047] The frame is provided with a double-layer structure and filled with an elastic inner protective layer 300 in this embodiment, thereby having high structural strength and certain buffering function, providing comprehensive protection for the photovoltaic panel and preventing it from being damaged, thereby prolonging the service life of the photovoltaic panel.

[0048] As shown in the exploded view of the inner frame and the inner protective layer provided in the embodiment of the present application, Figure 2 The inner frame 100 comprises a clamping mechanism 120 and an adjusting mechanism 110, and the adjusting mechanism 110 is fixed to the clamping mechanism 120. The clamping mechanism 120 is used for clamping the photovoltaic panel. The adjusting mechanism 110 is fixed to the clamping mechanism 120 and can control the action of the clamping mechanism 120. Specifically, the inner size of the clamping mechanism 120 is adjusted, thereby controlling the clamping of the photovoltaic panel by the clamping mechanism 120. For photovoltaic panels with different thicknesses, the clamping size of the clamping mechanism 120 can be adjusted by the adjusting mechanism 110, so that the clamping mechanism 120 can clamp photovoltaic panels with different thicknesses.

[0049] Figure 3 The inner frame and the inner protective layer provided in the embodiment of the present application are shown in the exploded view of the inner frame and the inner protective layer and the local enlarged view at position C. Figure 3As shown, the adjusting mechanism 110 includes an adjusting seat 111, a left limiting frame 112 and a right limiting frame 113, and the left limiting frame 112 and the right limiting frame 113 are symmetrically arranged on the clamping mechanism 120; the two ends of the adjusting seat 111 have a hollow structure, and the left limiting frame 112 and the right limiting frame 113 are arranged at the two ends of the adjusting seat 111, and are pullably connected with the adjusting seat 111 in the hollow structure.

[0050] The adjusting seat 111 can be provided as a plate-shaped structure with an arc-shaped middle part, and the arc-shaped structure can be matched with the clamping mechanism 120 and can reserve adjustment space for clamping action. The two ends of the adjusting seat 111 are provided as straight plates, and the inside is hollow, and the hollow structure is used to realize the pulling action of the limiting frame in the adjusting seat 111. Specifically, the end part of the limiting frame is inserted into the adjusting seat 111 to form a sliding connection relationship with the adjusting seat 111. The limiting frame can reciprocally move in the hollow structure of the adjusting seat 111 to form a pullable movable connection structure. In the embodiment, the adjusting seat 111 also has a fixing and limiting effect on the end part of the limiting frame.

[0051] Similarly, the adjusting mechanism 110 of the embodiment of the application includes left and right limiting frames, which are pullably connected with the two ends of the adjusting seat 111, and the purpose is to enable the adjusting mechanism 110 to be adjusted in two directions, so that the clamping mechanism 120 is more flexible and convenient to control and adjust.

[0052] Figure 6 A structure schematic diagram of the frame structure of the photovoltaic module for clamping and fixing the photovoltaic panel is provided in the embodiment of the application. As shown in Figure 6 The inner frame 100 is used for clamping the photovoltaic panel, and the outer frame 200 cooperates with the inner frame 100 to clamp the photovoltaic panel and fixes and protects the inner frame 100. The inner frame 100 is provided with a clamping mechanism 120 for clamping the photovoltaic panel, and the size of the inner space of the clamping mechanism 120 is adjusted through the adjusting mechanism 110, so that the clamping mechanism 120 can clamp photovoltaic panels with different thicknesses. The adjusting mechanism 110 includes an adjusting seat 111 and left and right limiting frames 112 and 113 connected at the two ends of the adjusting seat 111. The two ends of the adjusting seat 111 are provided with cavities, and the left and right limiting frames 112 and 113 are inserted into the cavities to realize a pullable movable connection with the adjusting seat 111. The distance between the left and right limiting frames 112 and 113 can be adjusted through the pullable connection, so that photovoltaic panels with different thicknesses can be clamped by adjusting the distance. The implementation manner can meet the fixing requirements of photovoltaic panels with various specifications through one frame structure, and can be mass-produced to reduce manufacturing cost. The double-frame structure can also improve the overall structural strength of the frame and provide stronger protection for the photovoltaic panel.

[0053] As shown in Figure 2As shown in FIG3 , the left limiting frame 112 and the right limiting frame 113 are fixed to the ends of the clamping mechanism 120. This embodiment is convenient for workers to operate, and the clamping work of the photovoltaic panel can be completed without the help of tools. The operation is simple and the work efficiency can be improved.

[0054] In one embodiment, the left limiting frame 112 and the right limiting frame 113 have the same structure, and the left limiting frame 112 and the right limiting frame 113 are symmetrically arranged on the clamping mechanism 120. Figures 2-3 As shown, the left limiting frame 112 or the right limiting frame 113 includes a limiting portion 1121 and a fixing portion 1122. The limiting portion 1121 is connected to the adjustment seat 111 in a pull-out manner; one end of the fixing portion 1122 is fixed to the limiting portion 1121, and the other end is fixed to the clamping mechanism 120.

[0055] In one embodiment, the limiting portion 1121 and the fixing portion 1122 are both bent plates, the fixing portion 1122 is fixedly connected to the limiting portion 1121, and a portion of the limiting portion 1121 is inserted into the adjusting seat 111 and is movably connected to the adjusting seat 111 in a pull-out manner. One end of the fixing portion 1122 is fixed to the limiting portion 1121 outside the adjusting seat 111, and the other end is fixedly connected to the clamping mechanism 120. The left limiting frame 112 or the right limiting frame 113 is fixed to the clamping mechanism 120 through the fixing portion 1122, and is movably connected to the adjusting seat 111 in a pull-out manner through the limiting portion 1121. The left limiting frame 112 or the right limiting frame 113 is fixed to the clamping mechanism 120, and is used to adjust the clamping thickness of the clamping mechanism 120 to meet the clamping needs of photovoltaic panels of different thicknesses.

[0056] like Figure 3 As shown, the limiting portion 1121 can be a structure similar to a right-angled U-shape, including a first side 1121a and a third side 1121c that are parallel to each other, and a second side 1121b that is perpendicular to the first side 1121a and the third side 1121c. One end of the fixing portion 1122 is fixedly connected to the second side 1121b, and the other end of the fixing portion 1122 is fixedly connected to the outer surface of the clamping mechanism 120. It can be seen that when the limiting portion 1121 slides within the adjustment seat 111, it can drive the clamping mechanism 120 to move together, thereby enabling the adjustment mechanism 110 to adjust the clamping size of the clamping mechanism 120, so that the clamping mechanism 120 can clamp photovoltaic panels of various thicknesses.

[0057] See also Figure 2 and Figure 3The clamping mechanism 120 includes a symmetrically arranged left clamping portion 121, a right clamping portion 122 and an elastic member 123 connecting the left clamping portion 121 and the right clamping portion 122; the left clamping portion 121 or the right clamping portion 122 is arranged in a U shape, and the left clamping portion 121 or the right clamping portion 122 includes an inner frame side plate 1211 and an inner frame vertical plate 1212, and the inner frame side plate 1211 and the inner frame vertical plate 1212 are vertically arranged along the edges of the two. The two ends of the elastic member 123 are respectively fixedly connected to the inner frame side plates 1211 of the left clamping portion 121 and the right clamping portion 122.

[0058] The left clamping portion 121 and the right clamping portion 122 have the same structural arrangement, both being composed of an inner frame side plate 1211 and an inner frame vertical plate 1212 , and the inner frame side plate 1211 and the inner frame vertical plate 1212 are arranged perpendicularly.

[0059] In one embodiment, the inner frame upright plate 1212 and the inner frame side plate 1211 are fixed vertically along their edges to form an L-shaped clamping portion.

[0060] The elastic member 123 can be configured as a wave-shaped structure with an arc-shaped protrusion, such as a semicircular arc. The elastic member 123 can be made of a plastic material with a certain degree of elasticity. The ends of the elastic member 123 are respectively fixed to the inner frame side panels 1211 of the left and right clamping portions 121, 122. The arc-shaped protrusion of the elastic member 123 matches the arc-shaped structure of the adjustment seat 111 described above, and the two do not contact each other.

[0061] In this embodiment, the clamping mechanism 120 comprises a left clamping portion 121, a right clamping portion 122, and an elastic member 123 connecting the left and right clamping portions 122. The distance between the left and right clamping portions 122 is the thickness of the photovoltaic panel that can be clamped. The U-shaped clamping mechanism 120 comprises the left clamping portion 121 and the right clamping portion 122, which are symmetrically arranged. When clamping photovoltaic panels of different thicknesses, the distance between the left and right clamping portions 122 can be adjusted by the expansion and contraction of the elastic member 123 to meet the clamping requirements of photovoltaic panels of different thicknesses.

[0062] like Figure 3 As shown, the limiting portion 1121 of the left limiting frame 112 or the limiting frame is a bent member, and a through hole 1212a can also be opened on the inner frame vertical plate 1212. One end of the limiting portion 1121 can be located in the through hole 1212a, and the other end of the limiting portion 1121 is movably connected to the adjustment seat 111 in a retractable manner; the fixing portion 1122 is a bent member, one end of the fixing portion 1122 is connected to the limiting portion 1121, and the other end of the fixing portion 1122 is fixedly connected to the inner frame vertical plate 1212. In this embodiment, the through hole 1212a opened on the inner frame vertical plate 1212 can meet the situation where the space is small and the limiting portion 1121 cannot be arranged.

[0063] In this embodiment, both the left and right clamping portions 122 are composed of inner frame side panels 1211 and inner frame upright panels 1212. The inner frame side panels 1211 and inner frame upright panels 1212 are arranged perpendicularly. Since the left and right clamping portions 122 are arranged symmetrically, the inner frame upright panels 1212 of the left and right clamping portions 122 are parallel to each other, and the inner frame side panels 1211 of the left and right clamping portions 122 are located in the same plane. One end of the fixing portion 1122 is fixedly connected to the portion of the limiting portion 1121 outside the adjustment seat 111, and the other end is fixed to the inner frame upright panels 1212, thereby providing support for the limiting portion 1121 and the adjustment seat 111. Therefore, the left limiting frame 112 or the right limiting frame 113 is respectively fixed to the left and right clamping portions 122 and operates in conjunction with the left and right clamping portions 122, respectively, to achieve the limiting control of the clamping mechanism 120 by the adjustment mechanism 110.

[0064] In one embodiment, the elastic member 123 is disposed in a U-shape along the outer surface of the inner frame side panels 1211. Specifically, the ends of the elastic member 123 are respectively fixed to the outer surfaces of the inner frame side panels 1211 of the left and right clamping portions 122, and the elastic member 123 is disposed along the outer surface of the inner frame side panels 1211.
