DETAILED DESCRIPTION

[0050] The embodiment of the present utility model discloses a clamp, the shell of which can be mounted on the installation base at the application site of the photovoltaic equipment by utilizing the card-mounting groove provided therein, and the locking knob can drive the clamping block to move to fix the above-mentioned installation base in the card-mounting groove. In this way, it is only necessary to hang the hook for assembling the photovoltaic equipment on the shell, that is, to utilize the shell as the actual installation base for the hook, to achieve the effect of unifying the specifications and sizes of the actual installation base, to facilitate the use of hooks of the same specifications, and to prevent the hooks of the same specifications from being directly assembled on the installation bases of different shapes and sizes on the site, which may cause difficulties in fixing or inability to hang them, thereby ensuring that the photovoltaic equipment can be applied on the site.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] See also Figures 1-17The present invention provides a clamp including a housing 101, a clamping block 103, and a locking knob 104. The housing 101 is provided with a mounting slot. The clamping block 103 is movably mounted on the housing 101 and is located within the mounting slot. The locking knob 104 is threadedly connected to the housing 101 and is configured to drive the clamping block 103 from a first sidewall of the mounting slot toward an opposite second sidewall of the mounting slot when the locking knob 104 is screwed into the mounting slot. The locking knob 104 is located on a side of the clamping block 103 facing away from the second sidewall.

[0053] The installation base is a beam of a balcony railing at the photovoltaic equipment application site, or a beam of a fixed bracket at the site, etc. This embodiment does not specifically limit the type of the installation base.

[0054] The card slot can be configured to be a "U"-shaped structure with three openings, including a first side wall and a second side wall that are oppositely arranged, and a bottom surface that is respectively connected to the first and second side walls.

[0055] When using the clamp described above, the clamping block 103 can be initially positioned within the mounting slot close to the first sidewall and away from the second sidewall, thereby leaving more space between the clamping block 103 and the second sidewall for subsequent steps. The housing 101 is then clamped onto the mounting base 201 from top to bottom. During this process, the mounting slot is in an inverted position, with the bottom facing upward and the opening opposite the bottom facing downward. When the mounting slot is inverted toward the mounting base 201, the mounting base 201 is positioned in the space between the clamping block 103 and the second sidewall. After that, turn the locking knob 104 so that the locking knob 104 gradually extends into the interior of the card slot and pushes the clamping block 103 toward the second side wall of the card slot. During this process, the clamping block 103 gradually approaches the mounting base 201 under the driving action of the locking knob 104 until the clamping block 103 and the second side wall clamp the two sides of the mounting base 201 and the locking knob 104 is locked, so that the entire clamp is fixed on the mounting base 201.

[0056] In the clamp provided in this embodiment, the shell 101 can be mounted on the installation base 201 at the photovoltaic equipment application site using the card-mounting groove provided on it, and the locking knob 104 can drive the clamping block 103 to move to fix the above-mentioned installation base 201 in the card-mounting groove, that is, to fix the entire clamp on the installation base 201. In this way, it is only necessary to hang the hook 202 for assembling the photovoltaic equipment on the shell 101, that is, to use the shell 101 as the actual installation base for the hook 202, so as to achieve the effect of unifying the specifications and sizes of the actual installation base, facilitate the use of hooks 202 of the same specifications, and prevent the hooks 202 of the same specifications from being difficult to fix or unable to be hung due to being directly assembled on the installation base 201 of different shapes and sizes on site, thereby ensuring that the photovoltaic equipment can be applied on site.

[0057] In one embodiment, the clamping blocks 103 are configured to be detachably mounted on the housing 101 ; the clamping blocks 103 are arranged in groups, which can be arranged in one group or multiple groups.

[0058] When the clamping blocks 103 are provided in multiple groups, each group of clamping blocks 103 is used to be replaced and installed on the housing 101 to adapt to different installation bases.

[0059] In this embodiment, the clamping block 103 is not only configured to be detachably mounted on the housing 101, but the clamping blocks 103 of different clamping block groups are also used to be replaced and installed on the housing 101, that is, different clamping block groups are not installed on the housing 101 at the same time, but according to the specific shape and structure of the on-site installation base 201, a group of clamping blocks 103 matching the installation base 201 can be selected to be assembled on the housing 101, thereby improving the adaptability of the clamp to the installation base 201 and the firmness of the clamp after being assembled to the installation base 201.

[0060] In a specific embodiment, the clamping block group can be set as two groups, wherein the surface of the clamping block 103 facing the second side wall in the first group is set as a plane, and the surface of the clamping block 103 facing the second side inner wall in the second group is set as an arc surface.

[0061] In another embodiment, the clamping block 103 is configured to be non-detachably mounted on the housing 101; in this case, there may be only one clamping block set, which is always mounted on the housing 101. This embodiment does not specifically limit whether the clamping block 103 is detachable.

[0062] In order to facilitate the installation of the clamping block 103, the housing 101 can be provided with a guide groove 111; the clamping block 103 can be slidably mounted in the guide groove 111, and the clamping block 103 can approach and move away from the second side wall when sliding along the guide groove 111.

[0063] The guide groove 111 is linear and is provided on the bottom surface of the card slot and is located near the first side wall. The reason for this arrangement is that the movable space of the clamping block 103 is located near the first side wall in the card slot, while the location near the second side wall in the card slot is used to accommodate the mounting base 201. Figure 8 、 10 , 14, 15. The guide groove 111 extends from the first side wall surface to the second side wall surface in the clamping groove, and can be specifically set to be perpendicular to both the first side wall surface and the second side wall surface.

[0064] Of course, a guide rail can also be provided on the shell 101, and the clamping block 103 can be slidably mounted on the guide rail. When the clamping block 103 slides along the guide rail, it can approach and move away from the second side wall surface; this embodiment does not limit the specific connection structure between the clamping block 103 and the shell 101.

[0065] In one embodiment, the clamping block 103 can be mounted with a guide screw 102. The guide screw 102 includes a screw rod and a head fixed to one end of the screw rod. During assembly, the screw rod of the guide screw 102 passes through the guide slot 111 and is tightened into the mounting hole 131 of the clamping block 103. The head of the guide screw 102 cannot pass through the guide slot 111, thereby allowing the clamping block 103 to be slidably mounted on the housing 101. In this embodiment, the guide screw 102 not only serves to mount the clamping block 103, preventing it from falling off, but also guides the clamping block 103, preventing it from being misaligned or offset during the process of clamping the mounting base 201.

[0066] A countersunk hole 132 can be set at the position corresponding to the locking knob 104 in the clamping block 103, and the locking knob 104 is pushed into the countersunk hole 132 of the clamping block 103 during the screwing process, so as to ensure that the locking knob 104 and the clamping block 103 do not slip off during the tightening process.

[0067] Furthermore, in order to prevent the head of the guide screw 102 from protruding from the surface of the housing 101, a recessed groove communicating with the guide groove 111 may be provided on the housing 101, and the head of the guide screw 102 is located in the recessed groove. Figure 5 、 8 , as shown in 14.

[0068] Scale markings 112 are provided on the housing 101 near the guide slot 111. Scale markings 112 indicate the distance from the second sidewall at various locations within the guide slot 111, facilitating quick adaptation to mounting bases 201 of varying sizes. Scale markings 112 extend in the same direction as the guide slot 111.

[0069] The guide groove 111 can be set to one, and the corresponding scale mark 112 is one. The guide groove 111 can also be set to multiple, and correspondingly, the scale marks 112 can be set to be the same number as the guide grooves 111 and correspond one to one. In the case where there are multiple guide grooves 111, the scale marks 112 can also be set to be less than the guide grooves 111, for example:

[0070] There are three guide slots 111 and two clamping block groups: Group A includes one clamping block 103, and Group B includes two clamping blocks 103. When the clamping blocks 103 of Group A are assembled to the housing 101, guide screws 102 are passed through each of the three guide slots 111 and connected to the clamping blocks 103. When the clamping blocks 103 of Group B are assembled to the housing 101, the first and second guide slots 111 are each passed through a guide screw 102 and connected to the same clamping block 103, while the third guide slot 111 is passed through a guide screw 102 and connected to another clamping block 103. In this case, the first and second guide slots 111 are always assembled with the same clamping block 103, and they can share a scale mark 112. The third guide slot 111 uses a separate scale mark 112.

[0071] This embodiment does not limit the number of scale marks 112 . It only needs to ensure that when different clamping block groups are installed on the housing 101 , each clamping block 103 can use the scale mark 112 to indicate the distance from the second side wall.

[0072] When there is one guide groove 111, the number of clamping blocks 103 in any clamping block group is one. When there are multiple guide grooves 111:

[0073] When the clamping block group installed on the housing 101 includes multiple clamping blocks 103, each guide groove 111 is used to clamp a different clamping block 103. In this case, the number of guide grooves 111 is the same as the number of clamping blocks 103 in the clamping block group. Alternatively, when the clamping block group installed on the housing 101 includes multiple clamping blocks 103, a portion of the guide grooves 111 is used to clamp different clamping blocks 103, and another portion of the guide grooves 111 is used to clamp the same clamping block 103. The number of the other portion of guide grooves 111 is multiple. For example, if there are three guide grooves 111, the clamping block group installed on the housing 101 includes two clamping blocks 103. The guide screw 102 passing through the first guide groove 111 is connected to one clamping block 103. The guide screws 102 passing through the second and third guide grooves 111 are connected to the other clamping block 103. The second and third guide grooves 111 are the aforementioned "other portion of guide grooves 111."

[0074] When the clamping block group installed on the housing 101 includes one clamping block 103 , all the guide slots 111 are used to clamp the same clamping block 103 , or only some of the guide slots 111 are used to clamp the clamping block 103 and the other guide slots 111 are idle.

[0075] In one embodiment, the number of locking knobs 104 is the same as the number of guide slots 111 , and the two correspond one to one, that is, the locking knob 104 is used to push the clamping block 103 clamped in the guide slot 111 corresponding to the locking knob 104 .

[0076] In another embodiment, the number of locking knobs 104 is greater than the guide grooves 111. Accordingly, at least part of the guide grooves 111 corresponds to multiple locking knobs 104. The clamping block 103 assembled at the at least part of the guide grooves 111 is tightened by the corresponding multiple locking knobs 104, which not only makes the clamping block 103 assembled at the at least part of the guide grooves 111 evenly stressed, but also improves the reliability of the clamping block 103 assembled at the at least part of the guide grooves 111 in cooperating with the second side wall clamping installation base 201.

[0077] The housing 101 is provided with threaded holes 113 that mate with the locking knobs 104. The threaded holes 113 are arranged in groups. The threaded hole groups can be arranged as a single group. In this case, the number of threaded holes 113 in the threaded hole group can be one or more, and this is not limited in this embodiment. The only requirement is to ensure that the locking knobs 104 installed in the threaded hole groups can tighten against the clamping blocks 103 in each clamping block group.

[0078] The threaded hole group can also be set to multiple groups. The number of threaded hole groups can be set in the following two ways:

[0079] ① The number of threaded hole groups can be set to be the same as the number of guide grooves 111, and the threaded hole groups and guide grooves 111 correspond one to one; the locking knobs 104 assembled at the threaded hole groups are used to drive the clamping blocks 103 assembled at the corresponding guide grooves 111 during the tightening process;

[0080] ② The number of threaded hole groups is less than the number of guide grooves 111, wherein at least some of the threaded hole groups correspond to multiple guide grooves; the locking knobs 104 assembled at the threaded hole groups are used to drive the clamping blocks 103 assembled at the corresponding guide grooves 111 during the tightening process;

[0081] For example, the number of threaded hole groups is set to 2 and the number of guide grooves 111 is set to 3; one threaded hole group corresponds to two guide grooves 111, and the two guide grooves 111 are always used to assemble the same clamping block 103; the locking knob 104 assembled at the one threaded hole group can tighten the clamping block 103 assembled at the two corresponding guide grooves 111; the other threaded hole group corresponds to the last guide groove 111.

[0082] The number of the threaded holes 113 in the threaded hole group can be set to one. The number of the threaded holes 113 in the threaded hole group can also be set to multiple.

[0083] If there are multiple threaded holes 113 in a threaded hole group, the diameters of the threaded holes 113 in the same group can be set to be the same or different to accommodate locking knobs 104 of different sizes. In practice, by selecting locking knobs 104 of different sizes and assembling them into corresponding threaded holes 113, the device can better adapt to rectangular cross-section mounting bases of different widths, circular cross-section mounting bases of different diameters, and other special-shaped mounting bases, thereby enhancing its applicability.

[0084] Of course, when the clamp is used, each threaded hole 113 in the same threaded hole group can be equipped with a locking knob 104, or only some of the threaded holes 113 in the same threaded hole group can be equipped with a locking knob 104. This embodiment does not limit whether all the threaded holes 113 in the same threaded hole group are equipped with a locking knob 104.

[0085] In the case where the threaded hole group includes multiple threaded holes 113, in one embodiment, the center points of the threaded holes in the same threaded hole group are located on the same straight line; when the housing 101 is assembled to the mounting base 201, the straight line on which the center points of the multiple threaded holes in the threaded hole group are located can be arranged in the vertical direction or in the horizontal direction, preferably arranged in a direction with an acute angle to the vertical direction. It can be understood by those skilled in the art that, in order to facilitate production, the surface of the mounting block 103 facing the first side wall is generally set to be rectangular, and the diagonal dimension of the rectangle is the largest; when the clamp is in normal use, if the straight line on which the center points of the threaded holes in the threaded hole group are located is arranged in a direction with an acute angle to the vertical direction, more threaded holes 113 can be arranged by utilizing the position on the housing corresponding to the diagonal of the clamping block 103, and it is beneficial to ensure that the locking knob 104 installed at each threaded hole 113 can be pushed against the clamping block 103.

[0086] In the case where the threaded hole group includes a plurality of threaded holes 113 , in another embodiment, the center points of the threaded holes 113 in the same threaded hole group are arranged in a circle.

[0087] Housing 101 can be configured as a semi-enclosed structure, comprising a first sidewall panel 115, a connecting panel 116, and a second sidewall panel 117, which are sequentially connected and form a snap-in slot. First sidewall panel 115 and second sidewall panel 117 are arranged opposite each other. The surface of first sidewall panel 115 facing second sidewall panel 117 is designated as the first sidewall surface, and the surface of second sidewall panel 117 facing first sidewall panel 115 is designated as the second sidewall surface. Locking knob 104 is mounted on first sidewall panel 115; clamping block 103 is movably mounted on connecting panel 116.

[0088] The clamp also includes a hook 202, which is used to hook onto the exterior of the housing 101 to assemble the photovoltaic device. A hook mounting slot 114 is provided on the exterior of the housing 101 to limit the hook 202 and prevent it from moving or misaligning along a first direction, which is parallel to the first and second sidewalls, respectively.

[0089] The clamp provided in this embodiment has a simple structure, is easy to manufacture, and is convenient to use. It can be quickly fixed to the installation base 201 simply by turning the locking knob 104 .

[0090] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0091] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
