Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a positioning connector. Background Art

[0002] In the current industrial manufacturing and construction fields, the connection and positioning of profiles is a crucial link. Especially in the construction process of streetscape building facilities, it is often faced with the connection between an upper profile and a lower profile. Although traditional connection methods, such as welding and bolt connection, can meet basic connection requirements, they have many shortcomings in positioning accuracy, assembly efficiency, and ease of disassembly.

[0003] In order to solve the above problems, a variety of new connector products have emerged in the market. However, most of these products have limitations in structural design and functional realization, and it is difficult to simultaneously meet the requirements of high-precision positioning, fast assembly and easy disassembly. Especially in situations where the connection position needs to be frequently replaced or adjusted, the traditional connection method is even more inadequate and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a positioning connector with high installation accuracy, rapid assembly and easy disassembly in view of the above problems.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a positioning connecting piece, which has the following structural features: it includes a connecting rod for connecting an upper profile and a lower profile, a pressure plate is installed at the lower end of the upper profile, a positioning hole is opened on the pressure plate, a pressing platform is provided on the connecting rod, a clamping plate spaced apart from the pressing platform is provided above the pressing platform, the shape of the clamping plate is adapted to the positioning hole, the clamping plate can be pressed against the upper side of the pressure plate after passing through the positioning hole and rotating, and also includes a support plate installed at the upper end of the lower profile, a limiting hole is opened on the support plate, and a positioning sleeve is installed at the lower end of the connecting rod and is locked to the lower end of the connecting rod after the connecting rod passes through the limiting hole.

[0006] Before assembly, the clamping plate needs to be welded to the bottom of the upper profile and the support plate needs to be welded to the top of the lower profile. The combination of the clamping plate and the press table enables the clamping plate to rotate after passing through the positioning hole, thereby pressing against the upper side of the clamping plate to achieve a tight connection to the upper profile. The positioning sleeve enhances the connection stability between the connecting rod and the lower profile, and prevents the loosening or movement of the connecting rod through the locking mechanism, ensuring the durability and safety of the connection. It is also easy to disassemble, has good stability, and can withstand large working loads.

[0007] A threaded hole is formed at the lower end of the connecting rod, a guide hole corresponding to the threaded hole is formed on the positioning sleeve, and a bolt passing through the guide hole and screwed into the threaded hole is installed on the positioning sleeve. The combined design of the bolt and the threaded hole provides a reliable locking mechanism, and the fastening connection between the connecting rod and the positioning sleeve can be achieved by rotating the bolt, so that the positioning sleeve and the support are used to position the support plate.

[0008] Two opposite cut surfaces are arranged on the lower peripheral surface of the connecting rod, and a guide edge fitting the cut surface is arranged on the inner hole of the positioning sleeve. The cut surface on the connecting rod and the guide edge in the positioning sleeve have a foolproof design, making the connecting rod smoother and faster when inserted into the positioning sleeve.

[0009] The lower profile is provided with operating holes for installing positioning sleeves and bolts. During the construction of multi-story buildings, the streetscape facilities on each floor are first built in the form of a house. At this time, the upper profile and the lower profile are located at the four corners of the streetscape facilities. Then the connecting parts are installed in the upper profile, and then the upper building is lifted and dropped onto the lower building. The upper and lower profiles at the corners are aligned, so that the press table falls onto the support bucket of the lower profile, and then the positioning sleeves and bolts are successively placed into the lower profile through the operating holes, and then the positioning sleeves are fixedly installed on the connecting rod. At this time, the positioning sleeves are located at the lower part of the support bucket. The design of the operating holes facilitates the installation and disassembly of the positioning sleeves and bolts, making the entire assembly process more convenient.

[0010] The support plate is provided with a downwardly concave support bucket, the bottom surface of the press platform is arc-shaped and matches the shape of the upper part of the support bucket, and the press platform is placed in the support bucket. The shapes of the support bucket and the press platform match each other, ensuring the stable position of the press platform in the support bucket and further enhancing the overall stability of the connector.

[0011] The limiting hole is arranged at the bottom of the supporting bucket, and the position selection of the limiting hole ensures that the connecting rod can accurately pass through and be fixed in the limiting hole at the bottom of the supporting bucket, thereby enhancing the connection stability and positioning accuracy between the connecting rod and the supporting plate.

[0012] The distance between the clamping plate and the pressing platform is not less than the thickness of the pressing plate, which ensures that the clamping plate will not interfere with the pressing plate when it rotates and presses against the pressing plate, thereby ensuring smooth assembly.

[0013] The clamping plate is rectangular in shape, and the positioning hole is rectangular enough for the clamping plate to pass through. The length of the long side of the clamping plate is greater than the width of the narrow side of the positioning hole. The rectangular design of the clamping plate and the size selection of the positioning hole ensure that the clamping plate can pass through the positioning hole smoothly and press against the pressure plate after rotation, while preventing the clamping plate from accidentally slipping out, thereby enhancing the reliability of the connection.

[0014] In summary, the beneficial effect of the present invention is that the positioning connector proposed in this scheme has significant advantages in structural design, function realization, etc., can meet the needs of high-precision and high-efficiency profile connection and positioning, and has broad market application prospects.

Figure 1Before assembly, it is necessary to weld the pressing plate 12 to the bottom of the upper profile 1 and weld the supporting plate 13 to the top of the lower profile 2. The combination of the clamping plate 6 and the pressing platform 7 can realize the rotation of the clamping plate 6 after passing through the positioning hole 3, so as to press against the upper side of the pressing plate 12, thereby realizing the fastening connection of the upper profile 1. The positioning sleeve 11 enhances the connection stability between the connecting rod 8 and the lower profile 2, and prevents the loosening or movement of the connecting rod 8 through the locking mechanism, thereby ensuring the durability and safety of the connection. It is easy to disassemble, has good stability, and can withstand a large working load. The lower end of the connecting rod 8 is provided with a threaded hole 9, and the positioning sleeve 11 is provided with a guide hole 10 corresponding to the threaded hole 9. The positioning sleeve 11 is installed with a bolt that passes through the guide hole 10 and is screwed in the threaded hole 9. The combined design of the bolt and the threaded hole 9 provides a reliable locking mechanism. The fastening connection between the connecting rod 8 and the positioning sleeve 11 can be realized by rotating the bolt, so that the positioning sleeve 11 and the supporting platform can be used to position the supporting plate 13. Two opposite cut surfaces are arranged on the lower circumference of the connecting rod 8, and a guide edge 5 fitting the cut surface is arranged on the inner hole of the positioning sleeve 11. The cut surface on the connecting rod 8 and the guide edge 5 in the positioning sleeve 11 have a foolproof design, making the connecting rod 8 smoother and faster when inserted into the positioning sleeve 11.

[0029] See attached Figure 7 , the lower profile 2 is provided with an operation hole 15 for installing the positioning sleeve 11 and the bolt. In the process of building a multi-story building, the streetscape facilities on each floor are first built in the form of a house. At this time, the upper profile 1 and the lower profile 2 are both located at the four corners of the streetscape facilities, and then the connector is installed in the upper profile 1. After that, the upper structure is lifted and dropped onto the lower structure, and the upper profile 1 and the lower profile 2 at the corners are aligned, so that the press table 7 falls on the support bucket 4 of the lower profile 2, and then the positioning sleeve 11 and the bolt are sequentially placed into the lower profile 2 through the operation hole 15, and then the positioning sleeve 11 is fixedly installed on the connecting rod 8. At this time, the positioning sleeve 11 is located at the lower part of the support bucket 4. The design of the operation hole 15 facilitates the installation and removal of the positioning sleeve 11 and the bolt, making the entire assembly process more convenient.

The position selection of the limiting hole 14 ensures that the connecting rod 8 can accurately pass through and be fixed in the limiting hole 14 at the bottom of the bucket 4, thereby enhancing the connection stability and positioning accuracy between the connecting rod 8 and the support plate 13.

[0031] See attached Figure 5The distance between the clamping plate 6 and the pressing platform 7 is not less than the thickness of the pressing plate 12, which ensures that the clamping plate 6 will not interfere with the pressing plate 12 when rotating and pressing against the pressing plate 12, thereby ensuring smooth assembly. Figure 1 The clamping plate 6 is rectangular, the positioning hole 3 is rectangular enough for the clamping plate 6 to pass through, and the length of the long side of the clamping plate 6 is greater than the width of the narrow side of the positioning hole 3. The rectangular design of the clamping plate 6 and the size selection of the positioning hole 3 ensure that the clamping plate 6 can pass through the positioning hole 3 smoothly and press against the pressing plate 12 after rotation, while preventing the clamping plate 6 from accidentally sliding out, thereby enhancing the reliability of the connection.
