DETAILED DESCRIPTION

[0034] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0035] As a specific embodiment, the hoisting fixing frame of the embodiment of the utility model includes a fixing frame 1 made of a metal sheet. The metal sheet refers to a metal object with a substantially uniform thickness, such as an iron sheet, a steel plate, a steel belt, etc. The fixing frame 1 is made of a metal sheet by stamping, sheet metal, etc.

[0036] The fixing frame 1 includes a support body 11, both ends of the support body 11 extend upward to form an extension body 12, and the top of the extension body 12 extends outward to form a mounting body 13. The mounting body 13 is provided with a mounting hole 139. Fig. 9 As shown, screws (not shown in the drawings) are passed through the mounting holes 139 and screwed into the ceiling wall of the room, etc., so that the mounting body 13 can be fixed on the ceiling wall of the room, etc., thereby achieving the installation of the fixing frame 1.

[0037] The support body 11 is provided with a clearance hole 111 . The clearance hole 111 is used to make way for the suspension rod 9 described later, so that the suspension rod 9 can pass through the clearance hole 111 .

[0038] As one of the specific implementations, the fixing frame 1 also includes a reinforcing arm 14, and the two ends of the reinforcing arm 14 are respectively fixedly connected to the extension body 12 or the mounting body 13 at the two ends of the support body 11. For example, the reinforcing arm 14 is an integrated strip, and its two ends are respectively welded and fixed to the mounting body 13 at the two ends of the support body 11. This ensures that the extension body 12 is not easily skewed and deformed, and the distance between the two extension bodies 12 remains stable, thereby ensuring the overall strength of the fixing frame 1. For the technical solution of the side contact body 22 fitting with the extension body 12 described later, it is possible to prevent the distance between the extension bodies 12 from being reduced, so that the connector 2 cannot be inserted between the two extension bodies 12.

[0039] As one of the specific implementations, the reinforcing arm 14 includes two inner extension sections 141, one end of the two inner extension sections 141 is integrally connected to one end of the two mounting bodies 13 (in other words, the joint of the mounting body 13 and the extension body 12), and the other ends of the two inner extension sections 141 are fixedly connected to each other. The reinforcing arm 14 can be provided without welding or other processes, which can simplify the production process and reduce costs.

[0040] As one of the specific implementations, the extension body 12 is provided with a reinforcing arm forming groove 124; when the extension body 12 and the mounting body 13 are flattened into a plane (in other words, the mounting body 13 is rotated about 90 degrees around the joint of the extension body 12 and the mounting body 13, so that the extension body 12 and the mounting body 13 are located in the same plane), the extension body 12 is located in the reinforcing arm forming groove 124. The reinforcing arm 14 can be formed without additional sheet material, which can reduce material costs.

[0041] As one of the specific implementations, the other ends of the two inner extension sections 141 (the other end of the mounting body 13 integrally connected to one end) are provided with docking holes 142, and there is an overlapping portion between the two docking holes 142. For example, the two docking holes 142 are two coaxial circular holes. After the screws are passed through the docking holes 142 and connected with the nuts, the other ends of the two inner extension sections 141 can be fixedly connected to each other. This facilitates the fixation of the other ends of the two inner extension sections 141.

[0042] As one of the specific implementations, one of the other ends of the two inner extension sections 141 is bent toward the support body 11 to form a bent section 143, and the other of the other ends of the two inner extension sections 141 is in contact with the bent section 143, so that the top ends of the two inner extension sections 141 are located in the same plane. There is no protrusion on the top end surface of the inner extension section 141, and after the fixing frame 1 is installed on the ceiling wall of the room, the top end surface of the inner extension section 141 can be in contact with the ceiling wall of the room, and the inner extension section 141 will not be bent due to the protrusion abutting against the ceiling wall of the room.

[0043] As one of the specific implementations, one of the docking holes 142 is provided with a connecting hole edge 144, and the connecting hole edge 144 is embedded in the other docking hole 142, so as to ensure accurate positioning between the two inner extension sections 141.

[0044] As one of the specific implementations, the inner wall of the connection hole edge 144 is provided with a thread, which can be formed by screwing in a screw as described later and tapping the screw, or can be formed by a conventional tapping process before screwing in a screw as described later; Figure 3 As shown, the inner cavity of the connecting hole edge 144 is directly opposite to the clearance hole 111. In other words, the inner cavity of the connecting hole edge 144 is completely located in the clearance hole 111 when viewed from above. When fixing the other ends of the two inner extension sections 141 to each other, the screw driver is attached to the screw head of the screw, and the screw is passed through the clearance hole 111, so that the screw moves from the support body 11 to the direction of the inner extension section 141, and then the screwdriver is rotated to screw the screw into the inner cavity of the connecting hole edge 144, without the need for a nut, so as to facilitate the fixing of the other ends of the two inner extension sections 141; in addition, the screw will not protrude from the top surface of the inner extension section 141, and the inner extension section 141 will not be bent due to the abutment between the screw and the ceiling wall of the room.

[0045] As one of the specific implementations, the support body 11 is provided with an upward anti-sway protrusion 112 , and a protrusion inner hole 113 is provided in the anti-sway protrusion 112 , so that the wall thickness of the anti-sway protrusion 112 is uniform.

[0046] As one of the specific implementations, the support body 11 is provided with a limiting groove 114, and the side wall of the limiting groove 114 (ie, the limiting side wall 115) has the same thickness as the support body 11. The limiting groove 114 can be formed by a process such as stamping.

[0047] As a specific embodiment, the suspension rod connector of the embodiment of the utility model includes a connector body 21, and the connector body 21 is provided with a suspension rod installation hole 211. The suspension rod installation hole 211 is used to realize the installation of the suspension rod 9.

[0048] Both ends of the connector body 21 are provided with side contact bodies 22. After the connector body 21 is placed on the support body 11, the side contact bodies 22 abut against or are close to the extension body 12, thereby preventing the connector 2 from rotating as a whole due to the suspension rod 9.

[0049] The edge of the suspension rod mounting hole 211 extends to form a mounting hole flange 213. The mounting hole flange 213 is used to connect with the suspension rod 9. The area of ​​the mounting hole flange 213 after flattening is less than or equal to the area of ​​the suspension rod mounting hole 211. For example, the suspension rod mounting hole 211 is circular, and the mounting hole flange 213 is formed by stamping two semicircular sheets (not shown in the drawings of this embodiment).

[0050] The side contact body 22, the mounting hole flange 213, and the connector body 21 have uniform and equal thickness, so that the connector 2 can be made of a metal sheet. For example, the connector 2 is made of a metal sheet by stamping, sheet metal, and other processes, which can reduce costs.

[0051] As one of the specific implementations, the side edge of the connector body 21 extends to form a side reinforcing edge 81, which is integrally connected to the side contact body 22 and has a height less than the height of the side contact body 22. The overall strength of the connector 2 can be ensured, and the connector 2 can be made of a metal sheet.

[0052] As one of the specific implementations, Figure 7 As shown, the mounting hole flange 213 is provided with two suspension rod pin grooves 214, and the two suspension rod pin grooves 214 are located on the same straight line, which is perpendicular to the side edge of the connector body 21. In other words, the straight line is parallel to the side contact body 22. The suspension rod pin 91 is passed through the suspension rod 9, and then the suspension rod 9 is passed through the suspension rod mounting hole 211, so that the suspension rod pin 91 is abutted against the inner wall of the suspension rod pin groove 214, and the suspension rod 9 can be installed on the connector 2 without screws, etc., which is convenient for installing the suspension rod 9.

[0053] As one of the specific implementations, the connector body 21 extends upward to form a sheet-like hanger pin stopper 215. When viewed along the straight line, the connector body 21 and the hanger pin slot 214 have overlapping portions. In other words, when viewed from the side in a direction perpendicular to the side edge of the connector body 21, the connector body 21 and the hanger pin slot 214 have overlapping portions. After the hanger 9 is passed through the hanger mounting hole 211 so that the hanger pin 91 abuts against the inner wall of the hanger pin slot 214, the end of the hanger pin 91 abuts against the hanger pin stopper 215, and the hanger pin 91 can be limited and prevented from detaching from the hanger 9 without a latch pin or the like (the vibration generated by the rotation of a ceiling fan or the like may cause the hanger pin 91 to detach from the hanger 9); in addition, if Fig. 9 As shown, the boom pin stopper 215 is elastic, and the boom pin 91 and the end thereof abut against the boom pin stopper 215 so that the boom pin 91 tends to be centered, thereby further preventing the boom pin 91 from detaching from the boom 9 .

[0054] As one of the specific implementations, the connector body 21 is provided with a stopper forming groove 216. When the suspension rod pin stopper 215 is flattened to be in the same plane as the connector body 21, all or part of the suspension rod pin stopper 215 is located in the stopper forming groove 216. The suspension rod pin stopper 215 can be formed by a sheet of raw material with only a width (the distance between the two sides of the connector body 21), which can reduce material costs.

[0055] As one of the specific implementations, the mounting hole flange 213 is provided with a suspension rod function hole 219. The suspension rod function hole 219 is used to fix a ground wire or the like on the mounting hole flange 213 by screws.

[0056] As one of the specific implementations, the connector body 21 is provided with an anti-sway hole 212 .

[0057] As a specific embodiment, the lifting structure of the embodiment of the utility model includes a fixing frame 1 and a connecting member 2.

[0058] The support body 11 is provided with a communication groove 119 , and the clearance hole 111 is exposed from one side of the support body 11 through the communication groove 119 .

[0059] The support body 11 is provided with an upward anti-sway protrusion 112 , and the connector body 21 is provided with an anti-sway hole 212 . The anti-sway protrusion 112 is inserted into the anti-sway hole 212 to prevent the connector 2 from rotating relative to the fixing frame 1 .

[0060] The working principle is that before use, the suspension rod 9 of the suspended device (not shown in the drawings) such as the ceiling fan and ceiling fan light is inserted into the suspension rod mounting hole 211 to fix the suspension rod 9 to the connector body 21 .

[0061] Fix the fixing frame 1 to the ceiling wall of the room, etc., and then translate the connecting member 2 and the hanging rod 9 so that the hanging rod 9 passes through the connecting groove 119 and enters the clearance hole 111, thereby completing the hanging of the suspended device such as the ceiling fan and the ceiling fan lamp.

[0062] The bottom end surface of the connecting member 2 is a plane without protrusions. During the translation of the connecting member 2 and the suspension rod 9, the connecting member 2 is not easily blocked, so it is easy to install.

[0063] As one of the specific implementations, the side contact body 22 abuts against or is close to the extension body 12 , which can further prevent the connecting member 2 from rotating relative to the fixing frame 1 .

[0064] As one of the specific implementations, the support body 11 is provided with a limiting groove 114, and the two sides of the connector body 21 are respectively against or close to the two side walls (i.e., limiting side walls 115) of the limiting groove 114, which can prevent the connector 2 from detaching from the fixing frame 1, further improving safety.

[0065] As one of the specific implementations, Fig.10As shown, the outer wall of the anti-sway protrusion 112 is a truncated cone with a small top diameter, and a through cylindrical protrusion inner hole 113 is provided in the anti-sway protrusion 112, and the bottom end of the anti-sway protrusion 112 abuts against the inner wall of the bottom end of the anti-sway hole 212. The anti-sway protrusion 112 can play a guiding role, making it easier for the anti-sway protrusion 112 to be inserted into the anti-sway hole 212. In addition, the anti-sway protrusion 112 is less difficult to form, which is conducive to reducing costs.

[0066] As used in this utility model, the terms: first, second, etc., do not indicate any order, quantity or importance, but are only used for distinction.

[0067] As used in the present invention, the terms "a", "an", etc. do not indicate a limitation of quantity, but rather indicate the presence of at least one of the referenced object.

[0068] For example, the terms indicating orientation or position used in the present invention, such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are intended to reflect relative positions rather than absolute positions.

[0069] As used in the present invention, terms such as approximately, overall, approximately, and similar are limiting terms that indicate that a feature exists but a certain deviation is allowed. The amount of the certain deviation allowed may vary depending on the specific context; for example, the specific context that may depend on the deviation of a dimension includes but is not limited to the national standard for dimensional tolerance.
