[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] Please refer to Figure 1 , is a three-dimensional structural schematic diagram of a mounting frame provided by an embodiment of the utility model, wherein the mounting frame includes a buckle 10, a pressure block 20, a rack 30 and a first rotating shaft 40.

[0034] The buckle 10 includes a top plate 110 and a bottom 120 away from the top plate 110 for holding the profile; the pressure block 20 is arranged in the buckle 10; the bottom of the rack 30 is connected to the pressure block 20; one end of the first rotating shaft 40 is placed in the buckle 10 and meshes with one side of the rack 30 through the gear 410, and the other end extends out of the buckle 10; wherein, by rotating the first rotating shaft 40, the rack 30 can drive the pressure block 20 to reciprocate in the buckle 10 from close to the top plate 110 to away from the top plate 110.

[0035] Specifically, the buckle 10 is an unclosed structure made of metal material, with the top being the top plate 110, and the bottom 120 being located on one side of the top plate 110, and usually arranged in pairs for holding the profile on the curtain wall of the building; the pressing block 20 is arranged inside the buckle 10, and is used to press the profile when the bottom 120 holds the profile, so as to achieve a fixed connection between the buckle 10 and the profile; the rack 30 is arranged above the pressing block 20, and the bottom of the rack 30 is fixedly connected to the pressing block 20, and the specific connection method can be an integrated connection, welding, or connection by screws, etc., and one side of the rack 30 has a tooth groove; the first rotating shaft One end of the first rotating shaft 40 extends into the interior of the buckle 10, which can be regarded as the connecting end. The other end of the first rotating shaft 40 is placed outside the buckle 10, which can be regarded as the operating end. The operating end is provided with a hexagonal operating hole for easy rotation with a hexagonal wrench. The gear 410 is fixedly connected to the connecting end of the first rotating shaft 40, and the gear 410 and the tooth grooves on the side of the rack 30 are meshed with each other. By rotating the gear 410, the rack 30 can be moved up and down, and then the rack 30 can drive the pressure block 20 to reciprocate in the buckle 10 from close to the top plate 110 to away from the top plate 110.

[0036] When in use, by rotating the operating end outside the buckle 10, the gear 410 follows the rotation, and then the rack 30 drives the pressing block 20 to reciprocate in the buckle 10 from close to the top plate 110 to away from the top plate 110. For example, when driving the pressing block 20 to move in the buckle 10 in the direction away from the top plate 110, the pressing block 20 descends and presses the building curtain wall profile in the buckle 10 to the bottom 120, so that a connection is formed between the buckle 10 and the profile, and the installation of the mounting frame is completed; for example, when driving the pressing block 20 to move in the buckle 10 in the direction close to the top plate 110, the pressing block 20 rises and releases the connection between the buckle 10 and the profile, and the disassembly of the mounting frame is completed, thereby realizing a quick and convenient installation of the mounting frame to the profile of the building curtain wall.

[0037] It should be pointed out here that when the pressure block 20 moves to the maximum limit in the buckle 10 toward the top plate 110, the end of the rack 30 away from the pressure block 20 can be extended above the top plate 110. At this time, a through hole for the rack 30 to pass through needs to be opened on the top plate 110; the end of the rack 30 away from the pressure block 20 can also always be below the top plate 110.

[0038] Please combine Figure 2-Figure 4 In other preferred embodiments of the utility model, the mounting frame also includes a base 50; the base 50 is connected to the side of the top plate 110 facing the pressure block 20, the rack 30 passes through the base 50, and one end of the first rotating shaft 40 is arranged in the base 50 and is provided with the gear 410.

[0039] Specifically, the base 50 is a box structure, usually made of metal material and connected to the bottom of the top plate 110. The specific connection method can be welding or screw connection. The connecting end of the first rotating shaft 40 and the gear 410 are placed in the base 50. The rack 30 passes through the upper and lower bottom surfaces of the base 50. The gear 410 is driven to rotate by the first rotating shaft 40, so that the rack 30 can pass through the upper and lower bottom surfaces of the base 50.

[0040] Furthermore, the mounting frame also includes a locking slider 60, which is disposed in the base 50 and can reciprocate in a direction from close to the rack 30 to away from the rack 30, and when close to the rack 30, it engages with a side of the rack 30 away from the first rotating shaft 30 through the protruding teeth 610.

[0041] Specifically, the locking slider 60 is arranged on the side of the rack 30 in the base 50 away from the gear 410, that is, the gear 410 and the locking slider 60 are separated on both sides of the received rack 30 in the base 50, and the convex tooth 610 is provided on the side of the locking slider 60 facing the rack 30, and the rack 30 is also provided with a tooth groove meshing with the convex tooth 610 on the side away from the gear 410. When the locking slider 60 moves toward the rack 30 until the convex tooth 610 meshes with the tooth groove on the rack 30, the rack 30 can be locked, that is, at this time the rack 30 cannot move up and down, and the corresponding pressing block 20 also becomes unable to move, thereby achieving locking.

[0042] Furthermore, the mounting frame also includes a spring 70 and a second rotating shaft 80 that drives the locking slider 60 to move, one end of the second rotating shaft 80 is arranged in the base 50 and connected to the locking slider 60, and the other end of the second rotating shaft 80 extends out of the buckle 10, and the spring 70 is arranged between the side of the locking slider 60 facing away from the rack 30 and the inner wall of the base 50.

[0043] Specifically, one end of the second rotating shaft 80 is arranged in the base 50 and connected to the locking slider 60, and is used to drive the locking slider 60 to reciprocate in the direction from close to the rack 30 to away from the rack 30. One end of the spring 70 abuts against the side of the locking slider 60 away from the rack 30, and the other end abuts against the inner wall of the base 50. The spring 70 can provide a certain rebound force for the reciprocating sliding of the locking slider 60. When the operation of the second rotating shaft 80 is stopped, the locking slider 60 can move toward the direction of the rack 30 and engage with it under the action of the elastic force of the spring 70, so as to lock the position of the rack 30.

[0044] In addition, the second rotating shaft 80 passes through the locking slider 60, and a protrusion 810 is provided on the outer wall of the second rotating shaft 80. The end face of the locking slider 60 is provided with a groove 620. The protrusion 810 is arranged in the groove 620, and when the second rotating shaft 80 rotates, it can contact the groove wall of the groove 620 and drive the locking slider 60 to move.

[0045] Specifically, the groove 620 on the end surface of the locking slider 60 is in a U-shaped structure, and the cross-section of the second rotating shaft 80 where the protrusion 810 is located is also in a U-shaped structure but is slightly smaller than the above-mentioned U-shaped structure. When the second rotating shaft 80 passes through the locking slider 60, the protrusion 810 is just accommodated in the groove 620. When the second rotating shaft 80 rotates, the protrusion 810 contacts the groove wall of the groove 620 and pushes the locking slider 60 to move. The second rotating shaft 80 can rotate clockwise or counterclockwise, that is, it can drive the locking slider 60 to move left and right, thereby realizing reciprocating movement from close to the rack 30 to away from the rack 30. For example, when the second rotating shaft 80 drives the protrusion 810 to rotate to a position facing the spring 70, the locking slider 60 moves toward the spring 70 and separates from the rack 30, thereby releasing the lock on the rack 30; when the second rotating shaft 80 drives the protrusion 810 to rotate to another position, the locking slider 60 moves toward the rack 30 under the thrust of the spring 70 and engages with it, thereby locking the rack 30.

[0046] It should be pointed out here that the end of the second rotating shaft 80 disposed outside the buckle 10 is provided with a hexagonal operating hole to facilitate the rotation operation thereof with a hexagonal wrench.

[0047] Furthermore, a slot 210 is provided on a side of the pressing block 20 facing away from the rack 30 . The slot 210 is V-shaped, and an opening of the slot 210 gradually decreases in a direction approaching the rack 30 .

[0048] Specifically, the slot 210 is an inverted V-shaped structure, that is, the slot 210 is a trumpet-shaped structure facing the building curtain wall profile. Such a structure facilitates the pressing block 20 to be connected and fixed with the end of the building curtain wall profile after moving downward.

[0049] Furthermore, a V-shaped rubber pad 220 is disposed in the slot 210 and has an opening facing away from the rack 30 .

[0050] Here, by providing a V-shaped rubber pad 220 with a certain elasticity at the opening of the slot 210, on the one hand, a certain buffering effect can be provided to avoid damage to the building curtain wall profile during installation, and on the other hand, the pressed connection between the buckle 10 and the building curtain wall profile can be made more secure.

[0051] In addition, the buckle 10 also includes a web 130 connected between the top plate 110 and the bottom 120, and the pressure block 20 is provided with a positioning column 230 on the side facing the buckle 10, and the web 130 is provided with a sliding hole 1301 that is consistent with the reciprocating movement direction of the pressure block 20 and is used to accommodate the positioning column 230.

[0052] Specifically, the web 130 is located between the top plate 110 and the bottom plate 120. The sliding hole 1301 is provided on the web 130. The sliding hole 1301 is in the shape of a long strip and is consistent with the reciprocating direction of the pressing block 20. The positioning column 230 is located on the side of the pressing block 20 facing the web 130 and can extend into the sliding hole 1301. When the pressing block 20 reciprocates, the positioning column 230 can also reciprocate in the sliding hole 1301. Here, the positioning column 230 and the sliding hole 1301 can be regarded as the track of the pressing block 20 when it reciprocates, to prevent it from deviating during movement, and to improve the reliability of the compression connection between the buckle 10 and the building curtain wall profile.

[0053] Furthermore, the buckle 10 is U-shaped, and two sides of the top plate 110 are respectively connected to one of the webs 130 , and the bottom 120 is a hook facing the web 130 on the opposite side.

[0054] Specifically, in order to make the bottom 120 more firmly embrace the building curtain wall profile, the buckle 10 can be designed into a U-shaped structure, with one web 130 connected to each side of the top plate 110, and the two webs 130 are located on the same side of the top plate 110, and a hook for embracing the building curtain wall profile is provided at one end of the web 130 away from the top plate 130, thereby achieving double-sided embracing of the building curtain wall profile and improving the reliability of the connection between the buckle 10 and the building curtain wall profile.
