Description

Technical Field

[0001] The utility model relates to the technical field of sleeve nut equipment, in particular to a pre-embedded sleeve nut. Background Art

[0002] In construction, especially when concrete needs to be hoisted, expansion bolts are often used for fixing. During construction, holes need to be drilled and the surface needs to be filled with plaster. This operation is cumbersome, affects the quality of the concrete, is labor-intensive and time-consuming, and has extremely low efficiency. Currently, embedded parts are usually used. The embedded parts are pre-embedded in the concrete. After the construction is completed, when decorating the ceiling, the hoisted objects need to be connected and fixed to the embedded parts pre-embedded in the concrete through threaded connections. Ordinary embedded parts are only provided with nuts with internal threads. When the embedded parts are installed and the cement concrete is poured, the cement mortar will flow into the internal threaded holes of the nuts, causing damage to the internal threads of the nuts, affecting installation and use. In addition, the use of ordinary embedded nuts has a small bearing capacity, is inconvenient to position, and is prone to movement during pouring, resulting in positional deviations.

[0003] Application number CN201420086507.9 discloses a pre-buried casing nut for construction, comprising a nut, a top plate integrally connected to the top of the nut, a plastic casing provided thereon, the nut tightly fitting over a perforation on the top of the casing, a retaining cap provided on the lower end face of the casing, and a mounting post integrally connected to the outer wall of the casing, the mounting post provided with a mounting hole. The utility model provides a retaining cap on the lower end face of the casing, preventing cement mortar from flowing into the perforation of the casing and damaging the internal threads of the nut. Nails are secured to the casing on the formwork through the mounting holes on the mounting post, ensuring accurate positioning of the pre-buried casing nut for construction. The utility model has a strong bearing capacity, saves time and effort, and facilitates construction, thus possessing considerable promotional value.

[0004] The above document discloses a pre-embedded sleeve nut for construction that has the following defects: the assembly is pre-embedded in concrete by means of nails and mounting columns. When the structure needs to be connected to other connectors to install and connect the concrete with the hoisted object, since the outer wall of the nut of the structure is relatively smooth, when a force is generated between the object and the concrete, the sleeve nut and the connecting bolt cannot maintain a stable connection.

[0005] It can be seen from this that the existing pre-buried sleeve nuts for construction do not have the function of firmly connecting concrete to the connection object. It is necessary to improve the existing deficiencies and provide a function that can firmly connect with the bolts in the connection object. Utility Model Content

[0006] The purpose of the utility model is to provide a pre-embedded sleeve nut to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a pre-embedded sleeve nut, comprising a fixing bolt and a sleeve nut, the sleeve nut being threadedly connected to the outer wall of the fixing bolt, the fixing bolt comprising a screw rod, a positioning groove being provided on one side outer wall of the screw rod, the positioning groove penetrating the screw rod, the sleeve nut comprising an externally threaded nut, six convex tooth blocks being arranged on the outer wall around each row of thread groove paths of the externally threaded nut, a plurality of positioning blocks being evenly arranged on the outer wall around one end of the externally threaded nut, a one-way pin being inserted on the inner wall of the positioning groove, wherein four of the positioning blocks are respectively located on both sides of the one-way pin. The purpose of such a setting is that during the use of the sleeve nut, the sleeve nut is rotated and drilled into the concrete through the thread path of the externally threaded nut, and the externally threaded nut is completely and firmly integrated with the air-dried concrete around the layers of convex tooth blocks provided on the outer wall of the externally threaded nut. The provided disc is in contact with the concrete. When the part needs to be taken out, the disc is flat and convenient for the sleeve nut to be taken out of the concrete. The provided screw hole is used to cooperate with the bolt of the connected object to achieve a firm connection between the object and the concrete. The screw is connected in the screw hole through the screw thread, and the nut blocks the upper surface of the connected object, and is fixed by a circle at one end of the externally threaded nut. The upper surface of the positioning block fixes the lower surface of the object, so that the object is effectively connected to the concrete, and the one-way pin is fixed in the screw through the positioning groove. One end of the one-way pin is arc-shaped and not easy to fall off in the positioning groove. The rod body of the one-way pin cooperates with the two adjacent positioning blocks. The two positioning blocks respectively limit and fix the two sides of the one-way pin, and then one end of the one-way pin is forked into two sections. The two sections are bent outward with a tool and close to the adjacent positioning blocks. In this way, the two ends of the one-way pin are respectively fixed on both sides of the positioning block, and the screw fixes the one-way pin, making the connection between the fixing bolt and the sleeve nut more stable, thereby enhancing the stability of the sleeve nut.

[0009] Furthermore, one end of the one-way pin extends outside the screw and externally threaded nut, and the extended end of the one-way pin is divided into two ends. This configuration is intended to ensure that when the sleeve nut is in use, the two ends of the one-way pin are fixed to the two sides of the positioning block, while the screw secures the one-way pin, making the connection between the fixing bolt and the sleeve nut more stable.

[0010] Furthermore, the extended ends of the one-way pin are each bent outward, with two of the bends adjacent to the outsides of four adjacent positioning blocks. This arrangement allows the two positioning blocks to position and secure the two sides of the one-way pin during use. The one-way pin is then forked into two sections at one end, which are then bent outward with a tool to align with adjacent positioning blocks, thus securing the two ends of the one-way pin to the sides of the positioning blocks.

[0011] Furthermore, a nut is provided at one end of the screw rod, and a disc is provided at the end of the externally threaded nut away from the nut. This arrangement is intended to ensure that when the sleeve nut is in use, the screw rod is threadedly connected to the screw hole, and the nut blocks the upper surface of the connected object. When the part needs to be removed, the disc is flat, making it easier to remove the sleeve nut from the concrete.

[0012] Furthermore, a screw hole is formed on the outer wall of the middle portion of one end of the externally threaded nut, and the screw hole passes through the externally threaded nut and the disc. This arrangement is intended to ensure that when the sleeve nut is in use, the screw is threaded into the screw hole, and the two ends of the one-way pin are respectively fixed to the two sides of the positioning block. The screw secures the one-way pin, thereby making the connection between the fixing bolt and the sleeve nut more stable.

[0013] Furthermore, a plurality of positioning blocks are distributed around the externally threaded nut with the screw hole as the center. This arrangement is intended to ensure that, during use of the sleeve nut, the rod of the one-way latch cooperates with two adjacent positioning blocks, which respectively position and fix the two sides of the one-way latch. The one-way latch is then forked into two sections at one end, which are then bent outward with a tool to align with the adjacent positioning blocks. This way, the two ends of the one-way latch are fixed to the two sides of the positioning blocks.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model provides a convex tooth block, a one-way pin and a positioning block. The layers of convex tooth blocks provided on the outer wall of the external threaded nut completely fuse the four sides of the external threaded nut with the air-dried concrete to achieve a firm connection. The rod of the one-way pin cooperates with the two adjacent positioning blocks. The two sections are bent outward with a tool to fit closely with the adjacent positioning blocks. In this way, the two ends of the one-way pin are respectively fixed on both sides of the positioning block, and the screw fixes the one-way pin, making the connection between the fixing bolt and the sleeve nut more stable.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
