Description

Technical Field

[0001] This utility model belongs to the field of bracket technology, and in particular relates to a high-strength limiting bracket. Background Technology

[0002] In the field of engineering technology, limit brackets are widely used in various structures to ensure the relative positional stability between structural components and prevent displacement or deformation caused by external forces. Especially in scenarios requiring the bearing of large loads, such as bridge support, building reinforcement, and mechanical equipment installation, the strength, stability, and ease of installation of limit brackets have become key performance indicators. Traditional limit brackets mostly adopt welding or one-piece molding designs, which, while providing a certain degree of strength and stability, present many inconveniences in installation, disassembly, and adjustment, and are difficult to adapt to the flexible needs of different installation environments. Utility Model Content

[0003] The purpose of this utility model is to provide a high-strength limiting bracket, which aims to solve the technical problem of the inconvenience of adjusting traditional brackets in the prior art.

[0004] To achieve the above objectives, this utility model provides a high-strength limiting bracket, including a fixed base, a support frame, an arc-shaped arch beam, and a locking assembly. The fixed base has a fixed cavity with an upper opening, and the support frame is detachably connected to the fixed base through the fixed cavity. Both ends of the support frame have upward-opening support cavities, and both ends of the arc-shaped arch beam extend into the corresponding support cavities, allowing the arc-shaped arch beam to be detachably connected to the support frame. The middle end of the support frame is recessed downwards to form a lower semi-circular groove, and the middle end of the corresponding arc-shaped arch beam is widened upwards to form an upper semi-circular groove, which together with the lower semi-circular groove form a forming cavity. Several vertically arranged connecting holes are vertically arranged in two rows on the side walls of both ends of the support cavity, and locking assemblies are connected to both ends of the corresponding arc-shaped arch beam. The locking assembly includes a connecting pipe, a main gear, two auxiliary gears, two racks, and a top extension. A connecting pipe with both ends is attached to the outward-facing sidewalls of the arched beam. A main gear is provided at the upper end of the connecting pipe, which meshes with two opposing auxiliary gears. Two racks are respectively set at the left and right ends of the connecting pipe, and the two ends of the racks are connected to the top extension pieces. Driven by the main gear, the two top extension pieces extend into the connecting hole to form a snap-fit.

[0005] Furthermore, the upper end of the arc-shaped arch beam is provided with an upper limit assembly, which includes an upper constraint member and an upper adjusting nut. The adjusting nut passes downward through the arc-shaped arch beam, and its driving end is connected to the upper constraint member to drive the upper constraint member to move closer to or away from the molding cavity.

[0006] Furthermore, the fixed base is provided with two lower limit components. The lower limit components include a lower constraint member and a lower adjusting nut. The lower adjusting nut is set inside the fixed base and extends out of the fixed base, and its driving end is connected to the lower constraint member to drive the lower constraint member to move closer to or away from the molding cavity.

[0007] Furthermore, the mounting base extends into mounting portions at both the front and rear ends, and the two mounting portions are provided with through mounting holes.

[0008] Furthermore, both ends of the curved arch beam are provided with strip grooves, and the left and right ends of the fixed seat are respectively provided with buffer movable parts that pass through the strip grooves. The buffer movable parts abut against the inner side wall of the strip groove to form a friction connection.

[0009] Furthermore, a rotating handle is connected to the surface of the main gear, and the rotating handle rotates synchronously with the main gear.

[0010] Furthermore, a guide bar is also provided inside the connecting pipe. The guide bar abuts against the upper end of the rack to guide the movement of the two racks.

[0011] The high-strength limiting bracket provided in this embodiment of the present invention has at least one of the following technical effects:

[0012] The left and right ends of the arched beam are connected to the corresponding left and right ends of the support frame. The workpiece is placed into the forming cavity, and the support frame is driven to press down. A main gear, two auxiliary gears, two racks, and a top extension are installed within the connecting pipe. Utilizing the gear transmission principle, when the main gear rotates, the two auxiliary gears rotate synchronously, driving the racks on both sides to move. This, in turn, drives the top extension to extend into the connecting holes on the side wall of the support cavity, achieving a secure connection and improving installation efficiency. The middle end of the support frame is recessed downwards to form a lower semi-circular groove, which cooperates with the upper semi-circular groove at the middle end of the arched beam to jointly form the forming cavity, enhancing the overall strength and stability of the structure. The arched bridge can effectively distribute the load, and the connection method between its two ends and the support frame is flexible, facilitating installation and adjustment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, a high-strength limiting bracket is provided, including a fixed base 100, a support frame 110, an arc-shaped arch beam 120, and a locking assembly 200. The fixed base 100 has a fixed cavity 130 with an upper opening, and the support frame 110 is detachably connected to the fixed base 100 through the fixed cavity 130. Both ends of the support frame 110 have upward-opening support cavities 140, and both ends of the arc-shaped arch beam 120 extend into the corresponding support cavities 140, thus forming a detachable connection between the arc-shaped arch beam 120 and the support frame 110. The middle end of the support frame 110 is recessed downward to form a lower semi-circular groove 151, and the middle end of the corresponding arc-shaped arch beam 120 is widened upward to form an upper semi-circular groove 152. The upper semi-circular groove 152 and the lower semi-circular groove 151 form a forming cavity 150. Several vertically arranged connecting holes 160 are provided on the side walls at both ends of the support cavity 140. Locking components 200 are connected to the left and right ends of the arc-shaped arch beam 120. The locking components 200 include a connecting pipe 210, a main gear 220, two auxiliary gears 230, two racks 240, and a top extension member 250. The connecting pipe 210, which runs through both ends, is attached to the side walls of the arc-shaped arch beam 120 facing outwards. The main gear 220 is provided at the upper end of the connecting pipe 210. The main gear 220 meshes with two opposing auxiliary gears 230. The two racks 240 are respectively provided at the left and right ends of the connecting pipe 210, and the top extension members 250 are connected to the ends of the two racks 240. Under the drive of the main gear 220, the two top extension members 250 extend into the connecting holes 160 to form a locking engagement.

[0028] Specifically, the left and right ends of the arched beam 120 are connected to the corresponding left and right ends of the support frame 110. The workpiece is placed into the forming cavity 150, and the support frame 110 is driven to press down. By setting a main gear 220, two auxiliary gears 230, two racks 240, and a top extension 250 in the connecting pipe 210, using the gear transmission principle, when the main gear 220 is rotated, the two auxiliary gears 230 rotate synchronously, driving the racks 240 on both sides to move, thereby driving the top extension 250 to extend into the connecting hole 160 on the side wall of the support cavity 140, achieving a firm engagement and improving installation efficiency. The middle end of the support frame 110 is recessed downward to form a lower semi-circular groove 151, which cooperates with the upper semi-circular groove 152 at the middle end of the arched beam 120 to jointly form the forming cavity 150, enhancing the overall strength and stability of the structure. The arched bridge can effectively distribute the load, and the connection method between its two ends and the support frame 110 is flexible, facilitating installation and adjustment.

[0029] Furthermore, both the main gear 220 and the secondary gear 230 rotate against the side wall of the connecting pipe 210, which in turn rests against the side wall of the arched beam 120. The left end of the main gear 220 passes through the guide bar 270 and engages with the first secondary gear 230; the right end of the main gear 220 passes through the guide bar 270 and engages with a connecting gear 231. The connecting gear 231 transmits power to the second secondary gear 230, causing both secondary gears 230 to move simultaneously in opposite directions under the drive of the main gear 220, thus allowing the two jacking members 250 to smoothly engage in the connecting hole 160. Due to the connecting gear 231, the two secondary gears 230 are at different heights on the horizontal line, resulting in the racks 240 on both sides being at different heights. This is to ensure that the main gear 220 meshes with the two compound gears.

[0030] Furthermore, the upper end of the arc-shaped arch beam 120 is provided with an upper limit assembly 300, which includes an upper constraint member 310 and an upper adjusting nut 320. The adjusting nut passes downward through the arc-shaped arch beam 120, and its driving end is connected to the upper constraint member 310 to drive the upper constraint member 310 to move closer to or further away from the forming cavity 150. Specifically, the upper constraint member 310 can be a plate-like structure that can fit tightly against the upper surface of the arc-shaped arch beam 120 and provide the necessary constraint force for the workpiece. By rotating the upper adjusting nut 320, the position of the upper constraint member 310 on the arc-shaped arch beam 120 can be changed. Therefore, when the nut moves downward, it drives the upper constraint member 310 to move downward as well, thereby reducing the forming cavity 150; conversely, when the nut moves upward, the upper constraint member 310 expands the forming cavity 150. The adjustment of the arc-shaped arch beam 120 can be achieved through a simple rotation operation without the need for complex tools or equipment.

[0031] Furthermore, the fixed base 100 is provided with two lower limiting components 400. Each lower limiting component 400 includes a lower constraint member 410 and a lower adjusting nut 420. The lower adjusting nut 420 is disposed within and extends out of the fixed base 100, and its driving end is connected to the lower constraint member 410 to drive the lower constraint member 410 to move closer to or further away from the forming cavity 150. Specifically, the lower constraint member 410 can be a plate-like structure that fits tightly against the inner surface of the arc-shaped arch beam 120 and provides the necessary constraint force to the workpiece. By rotating the two lower adjusting nuts 420, the position of the lower constraint member 410 on the arc-shaped arch beam 120 can be changed. Therefore, when the nut moves upward, it drives the upper constraint member 310 to also move upward, thereby reducing the forming cavity 150; conversely, when the nut moves downward, the lower constraint member 410 expands the forming cavity 150. In conjunction with the upper limiting component 300, the position of the lower constraint member 410 can be easily changed to accommodate workpieces of different sizes or shapes.

[0032] Furthermore, the mounting base 100 extends into mounting portions 500 at both the front and rear ends, and the two mounting portions 500 are provided with through mounting holes 510 for fixing the entire bracket.

[0033] Furthermore, both ends of the arched beam 120 are provided with strip grooves 600, and the left and right ends of the fixed base 100 are respectively provided with buffer movable members 610 that penetrate the strip grooves 600. The buffer movable members 610 abut against the inner sidewall of the strip groove 600 to form a friction connection. The buffer movable members 610 can be made of elastic materials, such as rubber or spring steel, to ensure that they can provide a good buffering effect when in contact with the inner sidewall of the strip groove 600, and the movement of the arched beam 120 into the support frame 110 is effectively restricted.

[0034] Furthermore, a rotating handle 260 is connected to the surface of the main gear 220, and the rotating handle 260 rotates synchronously with the main gear 220.

[0035] Furthermore, a guide bar 270 is provided inside the connecting pipe 210. The guide bar 270 abuts against the upper end of the rack 240 to guide the movement of the two racks 240, ensuring that the racks 240 can move along the predetermined path during the movement without deviation or misalignment.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
