Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to a high-efficiency plug-in rod connector. Background Art

[0002] The connection of prefabricated parts (such as pull-out piles, etc.) is mostly connected by welding in the prior art. After the pile bodies of two welded piles are aligned, the metal end plates of the pile heads are welded together by welding. This is not only inconvenient to operate, but also the welded metal plates at the connection are exposed and easily corroded, thus affecting the use effect and lifespan.

[0003] In the existing mechanical connections on the market, when the end faces of the pile heads are not in contact with each other smoothly, multiple connecting parts cannot be subjected to force at the same time, and the simultaneous force-bearing and pull-out resistance function is greatly reduced.

[0004] In order to solve the connection problem between pull-out piles and the problem of uneven end faces during connection, the existing quick strong pull butt fasteners and butt joints, the top pull nut in the quick butt fastener (composed of a quick butt buckle and a plug connector) is embedded in the end face of one end of a non-metallic body other than the prefabricated part, and the end face of the other end of the non-metallic body is inlaid with or has the tail of the plug connector, one end of the compression spring directly touches the bottom of the top pull nut, and the other end is provided with a conical sleeve composed of two or more pieces. When butt jointing, the head of the plug connector is plugged into the quick butt buckle. When making a non-metallic body other than a prefabricated part, a plurality of corresponding quick butt buckles and plug connectors are respectively fixed at the two ends of the non-metallic body (equivalent to one male and one female), and two or more non-metallic bodies with quick butt buckles and plug connectors are butt-connected. However, the above-mentioned existing connectors are relatively cumbersome to install in actual use, which leads to inconvenience in installation, and after installation, the pull-out resistance is poor. Therefore, in view of the above-mentioned problems, an efficient plug-in rod connector is now designed to better meet the actual use needs. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency plug-in connector to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an efficient plug-in rod connector, comprising a nut at the lower end of an upper section, wherein the nut at the lower end of the upper section is interconnected with a locking rod, the locking rod is interconnected with a shrinkable locking sleeve, and the shrinkable locking sleeve is threadedly connected to the nut at the upper end of the lower section.

[0007] Preferably, the lower end of the locking rod is a thick head, and chamfered angles are provided on the outer sides of the upper and lower ends of the thick head. The thick head can be used to limit the locking rod and the shrinkable locking sleeve after assembly to ensure the stability of the connection between the shrinkable locking sleeve and the locking rod.

[0008] Preferably, the lower end of the locking rod is a threaded head, and the threaded head and the closed sleeve are connected by screw threads, and chamfers are provided on the outer sides of the upper and lower ends of the thick head of the closed sleeve. The threaded head is connected to the closed sleeve, which can facilitate the installation of the contractile locking sleeve and can also be positioned after installation.

[0009] Preferably, the upper end of the locking rod is a coarse threaded joint, and the coarse threaded joint and the nut at the lower end of the upper section are threadedly connected. The stability of the connection between the locking rod and the nut at the lower end of the upper section can be ensured by connecting the coarse threaded joint to the nut at the lower end of the upper section.

[0010] Preferably, the upper end of the locking rod is a fine thread joint, and the fine thread joint and the inner and outer thread sleeves are threadedly connected. The fine thread joint can facilitate the installation of the shrinkable locking sleeve, and the shrinkable locking sleeve can be positioned in conjunction with the inner and outer thread sleeves.

[0011] Preferably, the shrinkable locking sleeve is provided with a notch, and slots are evenly provided on the shrinkable locking sleeve. Through the action of the notch and the slots, the shrinkable locking sleeve can have a certain elasticity, which can not only facilitate the installation of the shrinkable locking sleeve, but also increase the stress between the shrinkable locking sleeve and the upper end nut of the lower section through the elastic action of the shrinkable locking sleeve, thereby effectively ensuring the pull-out resistance of the connecting piece.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the efficient plug-in rod connector, the entire connector assembly is mainly connected and fixed by screw threads, which facilitates the assembly of the entire connector and effectively improves the installation efficiency of the connector, and by providing notches and grooves on the shrinkable locking sleeve, the convenience of installing the shrinkable locking sleeve can be improved, and the reliability of the connector can be improved. When there is tension between the prefabricated parts, the elasticity of the shrinkable locking sleeve automatically expands the screw thread connection between the nut at the upper end of the lower section, and the cooperation between the thick head and the shrinkable locking sleeve can expand the shrinkable locking sleeve to a certain size, thereby increasing the screw thread connection effect between the shrinkable locking sleeve and the nut at the upper end of the lower section, and then effectively improving the pull-out resistance of the device.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 10 The utility model provides a technical solution: an efficient plug-in rod connector, including an upper section lower end nut 1, the upper section lower end nut 1 and the locking rod 2 are interconnected, the locking rod 2 and the shrinkage locking sleeve 3 are interconnected, and the shrinkage locking sleeve 3 and the lower section upper end nut 4 are threadedly connected.

[0026] The lower end of the locking rod 2 is a thick head 201, and the outer sides of the upper and lower ends of the thick head 201 are provided with chamfered angles; the upper end of the locking rod 2 is a thick thread joint 203, and the thick thread joint 203 is connected to the nut 1 at the lower end of the upper section by a threaded connection; the shrinkable lock sleeve 3 is provided with a notch 301, and the shrinkable lock sleeve 3 is also evenly provided with slots 302;

[0027] Embodiment 1:

[0028] like Figure 1-Figure 3As shown, the entire connector is composed of an upper section lower end nut 1, a locking rod 2, a thick head 201, a thick threaded joint 203, a shrinkage lock sleeve 3 and a lower section upper end nut 4. During installation, the upper section lower end nut 1 and the lower section upper end nut 4 are respectively fixed to the upper and lower prefabricated parts, and the shrinkage lock sleeve 3 is matched with the thick head 201 and hammered. Through the effects of the notch 301 and the slot 302, the shrinkage lock sleeve 3 can be made elastic, which is convenient for hammering to make the shrinkage lock sleeve 3 open outwards under the action of the thick head 201, thereby facilitating the shrinkage lock sleeve 3 and the thick head 201 to slide. Until the shrinkage lock sleeve 3 is separated from the thick head 201 and matched with the locking rod 2 (the upper section lower end nut 1 and the lower section upper end nut 4 are embedded in advance when the prefabricated parts are cast, so that the upper section lower end nut 1 and the lower section upper end nut 4 are respectively integrated with the two prefabricated parts, which are directly produced in the factory, and the shrinkage lock sleeve 3 and the thick head 201 are directly assembled when produced in the hardware factory, and can be directly installed on the subsequent construction site), then the thick head 201 is threadedly connected to the upper section lower end nut 1, and finally the shrinkage lock sleeve 3 is threadedly connected to the lower section upper end nut 4 to achieve installation, such as Figure 8 As shown, at this time, the upper and lower ends of the shrinkable locking sleeve 3 are in contact with the coarse threaded joint 203 and the coarse head 201 respectively. When tension is generated between the two prefabricated parts, the coarse head 201 cooperates with the shrinkable locking sleeve 3. Since the inner diameter of the shrinkable locking sleeve 3 is smaller than the outer diameter of the coarse head 201, during the cooperation between the coarse head 201 and the shrinkable locking sleeve 3, the coarse head 201 exerts a force on the shrinkable locking sleeve 3 to make the shrinkable locking sleeve 3 open outward, thereby increasing the locking effect between the shrinkable locking sleeve 3 and the nut 4 at the upper end of the lower section, thereby ensuring the anti-pullout performance of the connecting piece. First, the shrinkable locking sleeve 3 is passed through the coarse head 201 of the locking rod 2 in the factory and combined with the locking rod 2 to form an integrated connecting piece. The construction personnel on the construction site only need to put the factory-assembled connecting piece The coarse thread joint 203 is screwed into the multiple upper section lower end nuts 1 on the prefabricated part one by one, and then the multiple connected connectors are inserted into the multiple lower section upper end nuts 4 on the lower section prefabricated part at the same time by using the self-weight of the upper section pile, so that the external thread of the shrinkage lock sleeve 3 is connected with the internal thread of the lower section upper end nut 4. The coarse head 201 exerts a force on the shrinkage lock sleeve 3 to make the shrinkage lock sleeve 3 open outward, thereby increasing the locking effect between the shrinkage lock sleeve 3 and the lower section upper end nut 4. The external thread length of the shrinkage lock sleeve 3 can be regarded as an effective connection length. When the end face of the prefabricated part is uneven or the gap is different, multiple connectors can be connected to ensure that the shrinkage lock sleeve 3 of each connector is locked synchronously with the lower section upper end nut 4, thereby ensuring the pull-out resistance.

At this time, the upper and lower ends of the shrinkable locking sleeve 3 are respectively connected to the coarse threaded joint 20 3 is in contact with the closed sleeve 5 (wherein the upper section lower end nut 1 and the lower section upper end nut 4 are embedded in advance when the prefabricated parts are cast, so that the upper section lower end nut 1 and the lower section upper end nut 4 are respectively integrated with the two prefabricated parts, which are directly produced in the factory, and the shrinkage lock sleeve 3, the threaded head 202 and the closed sleeve 5 are directly assembled when the hardware factory produces them, and can be directly installed on the subsequent construction site), and then the thick head 201 is threadedly connected with the upper section lower end nut 1, and finally the shrinkage lock sleeve 3 is threadedly connected with the lower section upper end nut 4 to achieve installation, such as Fig. 9 As shown, when tension is generated between the two prefabricated parts, the closing sleeve 5 cooperates with the shrinkage locking sleeve 3. Since the inner diameter of the shrinkage locking sleeve 3 is smaller than the outer diameter of the closing sleeve 5, during the cooperation process between the closing sleeve 5 and the shrinkage locking sleeve 3, the closing sleeve 5 exerts a force on the shrinkage locking sleeve 3 to make the shrinkage locking sleeve 3 open outward, thereby increasing the locking effect between the shrinkage locking sleeve 3 and the nut 4 at the upper end of the lower section, thereby ensuring the anti-pullout performance of the connecting piece. First, the shrinkage locking sleeve 3 is passed through the threaded head 202 on the locking rod 2 in the factory, and then the closing sleeve 5 is combined and connected with the threaded head 202 of the locking rod 2 to form an integrated connecting piece. The construction personnel on the construction site only need to tighten the coarse thread joints 203 on the factory-assembled connecting piece one by one. Insert into multiple upper section lower end nuts 1 on the prefabricated part, and then use the self-weight of the upper section pile to insert the connected multiple connecting parts into multiple lower section upper end nuts 4 on the lower section prefabricated part at the same time, so that the external thread of the shrinkage locking sleeve 3 is connected with the internal thread of the lower section upper end nut 4, and the closing sleeve 5 generates a force on the shrinkage locking sleeve 3 to make the shrinkage locking sleeve 3 open outward, thereby increasing the locking effect between the shrinkage locking sleeve 3 and the lower section upper end nut 4. The external thread length of the shrinkage locking sleeve 3 can be regarded as an effective connection length. When the end face of the prefabricated part is uneven or the gap is different, multiple connecting parts can be connected to ensure that the shrinkage locking sleeve 3 of each connecting part is locked synchronously with the lower section upper end nut 4, thereby ensuring the anti-pullout performance;

During installation, the upper section lower end nut 1 and the lower section upper end nut 4 are respectively fixed to the upper and lower prefabricated parts, and then the shrinkable locking sleeve 3 is assembled with the locking rod 2 through the upper end of the locking rod 2, and the shrinkable locking sleeve 3 is positioned by connecting the inner and outer thread sleeve 6 with the fine thread joint 204. At this time, the upper and lower ends of the shrinkable locking sleeve 3 are respectively fixed to the inner and outer thread sleeve 6. and the thick head 201 (wherein the upper section lower end nut 1 and the lower section upper end nut 4 are embedded in advance when the prefabricated parts are cast, so that the upper section lower end nut 1 and the lower section upper end nut 4 are respectively integrated with the two prefabricated parts, and are directly produced in the factory, and the shrinkage locking sleeve 3, the fine thread joint 204 and the inner and outer thread sleeves 6 are directly assembled during production in the hardware factory, and can be directly installed on the subsequent construction site), and then the inner and outer thread sleeves 6 are threadedly connected to the upper section lower end nut 1, and finally the shrinkage locking sleeve 3 is threadedly connected to the lower section upper end nut 4 to achieve installation, such as Fig.10 As shown, when tension is generated between the two prefabricated parts, the thick head 201 cooperates with the shrinkage locking sleeve 3. Since the inner diameter of the shrinkage locking sleeve 3 is smaller than the outer diameter of the thick head 201, during the cooperation between the thick head 201 and the shrinkage locking sleeve 3, the thick head 201 generates a force on the shrinkage locking sleeve 3, which can make the shrinkage locking sleeve 3 open outward, thereby increasing the locking effect between the shrinkage locking sleeve 3 and the nut 4 at the upper end of the lower section, thereby ensuring the anti-pullout performance of the connecting piece. First, the shrinkage locking sleeve 3 is passed through the fine thread joint 204 of the locking rod 2 in the factory, and then the inner and outer thread sleeves 6 are combined and connected with the fine thread joint 204 of the locking rod 2 to form an integrated connecting piece. The construction personnel on the construction site only need to tighten the inner and outer thread joints on the connecting piece assembled in the factory. The sleeves 6 are screwed into the multiple upper section lower end nuts 1 on the prefabricated part one by one, and then the multiple connected connectors are inserted into the multiple lower section upper end nuts 4 on the lower section prefabricated part as a whole by using the self-weight of the upper section pile, so that the external thread of the shrinkage locking sleeve 3 is connected with the internal thread of the lower section upper end nut 4, and the thick head 201 exerts a force on the shrinkage locking sleeve 3 to make the shrinkage locking sleeve 3 open outward, thereby increasing the locking effect between the shrinkage locking sleeve 3 and the lower section upper end nut 4. The external thread length of the shrinkage locking sleeve 3 can be regarded as the effective connection length. When the end face of the prefabricated part is uneven or the gap is different, multiple connectors can be connected to ensure that the shrinkage locking sleeve 3 of each connector and the lower section upper end nut 4 are locked synchronously, thereby ensuring the anti-pullout performance.
