Description

Technical Field

[0001] This application relates to the technical field of auxiliary tools for the production of throttling pipe seats, and in particular to a nut mounting clamp for throttling pipe seats. Background Technology

[0002] During production, some flues require the installation of throttling tube seats according to the actual needs of the converter. The throttling tube seat has an installation groove that is compatible with the throttling tube and communicates with its own interior. After the throttling tube seat is installed on the flue, the operator usually needs to manually insert one end of the throttling tube into the installation groove and thread the threaded end of the throttling tube to the throttling tube seat. Then, the nut with a smaller diameter and an external thread is inserted and installed at the other end of the throttling tube, completing the installation of the throttling tube and nut.

[0003] In related technologies, one end of the throttling tube is manually inserted into the installation groove and threaded to the throttling tube seat. Then, the nut is aligned with the other end of the throttling tube and installed on the throttling tube. This process can easily cause inconvenience in installation and thus adversely affect installation efficiency. Utility Model Content

[0004] To reduce the adverse impact on work efficiency, this application provides a nut mounting clamp for a throttling pipe seat.

[0005] The technical solution provided in this application for a nut mounting clamp for a throttling tube seat is as follows:

[0006] A nut mounting clamp for a throttling tube seat includes a screw rod that can be inserted into a throttling tube and threadedly connected to the inside of the throttling tube. A sleeve is fitted around the outside of the screw rod and is slidably and rotatably connected to the screw rod. One end of the sleeve has an insertion groove that is adapted to the nut and has a width greater than the inner diameter of the sleeve. The length of the screw rod is greater than the length of the sleeve.

[0007] By adopting the above technical solution, the nut is sleeved on the outside of the screw and inserted into the insertion groove. The end of the screw is inserted into the throttling tube and threaded. The drive sleeve drives the screw to move to the throttling tube seat. The drive screw is inserted into the throttling tube seat and rotated until the end of the throttling tube is installed on the throttling tube seat through its own external thread. The screw is rotated in the opposite direction until it is disengaged from the throttling tube. The sleeve is turned to drive the nut to rotate until the end of the nut with external thread is inserted and threaded to the end of the throttling tube away from the throttling tube seat. This facilitates the installation of the throttling tube while aligning the nut with the end of the throttling tube, reducing the possibility of manually removing the nut after installing the throttling tube and reducing the adverse impact on work efficiency.

[0008] Optionally, a limiting rod perpendicular to the screw is fixedly connected to the end of the screw away from the insertion slot, and fixing rods are fixedly connected to both sides of the sleeve near the outer side of the end of the sleeve close to the limiting rod.

[0009] By adopting the above technical solution, the limiting rod makes it difficult for the end of the screw close to the limiting rod to enter the sleeve when rotating, and facilitates the rotation of the screw. The fixing rod makes it easy for the operator to hold the sleeve and drive the sleeve to rotate, reducing inconvenience in use and further reducing the adverse impact on work efficiency.

[0010] Optionally, an electromagnet ring is inserted into and fixedly connected to the inner wall of the sleeve near the insertion slot.

[0011] By adopting the above technical solution, the nut is installed in the insertion slot. When the electromagnet ring is energized, the nut is attracted to the inner wall of the sleeve by the electromagnet ring, which improves the stability of the installation of the nut and the sleeve, facilitates the sleeve to drive the nut to rotate, reduces the possibility of the sleeve falling off the sleeve during the process of moving the sleeve and approaching the throttling tube, and reduces the adverse impact on work efficiency.

[0012] Optionally, a limiting component is provided between the sleeve and the screw to connect the two.

[0013] By adopting the above technical solution, the sleeve is connected to the screw through the limiting component, thereby limiting the screw in the length direction of the sleeve and reducing the possibility of the screw detaching from the sleeve from the end of the sleeve near the fixed rod.

[0014] Optionally, the limiting assembly includes a limiting ring sleeved on the outside of the screw and fixedly connected to the screw. The sleeve has a moving groove with a diameter larger than the inner diameter of the sleeve. The limiting ring is inserted into the moving groove and slides along the length of the sleeve. The sleeve has a spring located on the side of the limiting ring away from the fixed rod and facing the limiting ring.

[0015] By adopting the above technical solution, when the throttling tube is installed by the screw, the limiting ring slides and rotates with the sleeve through the moving groove. At this time, the spring is compressed. After the screw is reversed and disengaged from the throttling tube, the spring restores its deformation and pushes the screw to reset, reducing the possibility of the screw falling out of the sleeve and further reducing the adverse impact on work efficiency.

[0016] Optionally, the spring has a contact ring on the side near the limiting ring, and the contact ring is rotatably connected to the limiting ring.

[0017] By adopting the above technical solution, the spring contacts the limiting ring through the contact ring, reducing the possibility of the spring end hindering the rotation of the limiting ring and reducing the adverse impact on work efficiency.

[0018] Optionally, the sidewall of the limiting ring is provided with balls that contact the sidewall of the contact ring.

[0019] By adopting the above technical solution, the ball bearings reduce the frictional force generated between the limiting ring and the side wall of the contact ring when the limiting ring rotates, which further facilitates the drive screw to install the throttle tube on the throttle tube seat and reduces the adverse impact on work efficiency.

[0020] Optionally, an electromagnet block is inserted and fixedly connected to the end of the screw away from the limiting rod.

[0021] By adopting the above technical solution, the throttling tube is installed on the screw. At this time, the electromagnet is energized, which helps to improve the stability of the installation of the throttling tube and the screw, and reduces the possibility of relative movement of the throttling tube in the length direction of the screw when installing the throttling tube by rotating the screw. After the installation is completed, the electromagnet is de-energized, which makes it easier to remove the screw from the throttling tube and reduce the adverse effects on work efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] Fit the nut onto the outside of the screw and insert it into the slot. Connect the end of the screw to the throttling tube and thread it. Drive the sleeve to move the screw to the throttling tube seat. Insert the screw into the throttling tube seat and rotate the screw until the end of the throttling tube is installed on the throttling tube seat through its own external thread. Rotate the screw in the opposite direction until it is disengaged from the throttling tube. Tighten the sleeve to rotate the nut until the threaded end of the nut is inserted and threaded to the end of the throttling tube away from the throttling tube seat. This makes it easy to install the throttling tube while aligning the nut with the end of the throttling tube, reducing the possibility of manually removing the nut after installing the throttling tube and reducing the adverse impact on work efficiency.

[0024] Install the nut in the insertion slot and energize the electromagnet ring. At this time, the nut is attracted to the inner wall of the sleeve by the electromagnet ring, which improves the stability of the installation of the nut and the sleeve, makes it easier for the sleeve to drive the nut to rotate, reduces the possibility of the sleeve falling off the sleeve during the process of moving the sleeve and approaching the throttling tube, and reduces the adverse impact on work efficiency.

[0025] When installing the throttle tube via the screw, the limiting ring slides and rotates with the sleeve through the moving groove. At this time, the spring is compressed. After the screw is reversed and disengaged from the throttle tube, the spring returns to its original deformation and pushes the screw back to its original position, reducing the possibility of the screw falling out of the sleeve and further reducing the adverse impact on work efficiency.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a nut mounting clamp for a throttling tube seat. Example

[0032] Reference Figure 1 A nut mounting clamp for a throttling tube seat includes a screw 1 adapted to the throttling tube. One end of the screw 1 is fixedly connected to a limiting rod 11 perpendicular to the length direction of the screw 1. The end of the screw 1 away from the limiting rod 11 is inserted into the throttling tube and threadedly connected to the inner wall of the throttling tube. A sleeve 2 with an inner diameter larger than the diameter of the screw 1 is sleeved on the outside of the screw 1. The end of the screw 1 away from the limiting rod 11 passes through the sleeve 2 and is slidably and rotatably connected to the sleeve 2, and the length of the screw 1 is greater than the length of the sleeve 2.

[0033] Two fixing rods 21, symmetrically arranged on both sides of the rotation axis of the sleeve 2, are fixedly connected to the outer side of the sleeve 2 near the limiting rod 11. The fixing rods 21 are perpendicular to the length direction of the sleeve 2. (Refer to...) Figure 1 and Figure 2 The inner wall of the sleeve 2 away from the fixed rod 21 is provided with a plug groove 22 that is compatible with the nut. The cross-section of the plug groove 22 is hexagonal.

[0034] Fit the nut onto the outside of the screw 1 and insert it into the insertion slot 22. Insert the end of the screw 1 into the throttling tube and connect it with the inner wall of the throttling tube by thread. Drive the sleeve 2 to move the screw 1 to the throttling tube seat. Drive the screw 1 into the throttling tube seat and rotate the screw 1 until the end of the throttling tube is installed on the throttling tube seat through its own external thread. Rotate the screw 1 in the opposite direction until it is disengaged from the throttling tube.

[0035] Tighten the sleeve 2 to rotate the nut. At this time, the shape of the insertion groove 22 causes the nut to rotate with the sleeve 2 until the end of the nut with external thread is inserted and threaded to the end of the throttle tube away from the throttle tube seat, thus completing the installation of the throttle tube and the nut.

[0036] The limiting rod 11 prevents the end of the screw 1 near the limiting rod 11 from entering the sleeve 2 during rotation, and facilitates the rotation of the screw 1. The fixing rod 21 makes it easy for the operator to hold the sleeve 2 and drive the sleeve 2 to rotate, reducing inconvenience in use.

[0037] The implementation principle of Example 1 is as follows: the drive screw 1 is inserted into the throttling tube seat and the screw 1 is rotated until the end of the throttling tube is installed on the throttling tube seat through its own external thread. The drive screw 1 is disengaged from the throttling tube, and the sleeve 2 is turned to drive the nut to rotate until the end of the nut with external thread is inserted and threaded to the end of the throttling tube away from the throttling tube seat, thus completing the installation of the throttling tube and the nut. Example

[0038] Reference Figure 3 The difference between this embodiment and embodiment 1 is that an electromagnet ring 3 is provided in the inner side wall of the sleeve 2 near the insertion groove 22, a cavity 23 is opened in the side wall of the sleeve 2, the electromagnet ring 3 is located in the cavity 23 and is fixedly connected to the sleeve 2, and a limiting component 4 connecting the sleeve 2 and the screw 1 is provided.

[0039] When the nut is installed in the insertion slot 22 and the electromagnet ring 3 is energized, the nut is attracted to the inner wall of the sleeve 2 by the electromagnet ring 3, which improves the stability of the installation of the nut and the sleeve 2 and reduces the possibility of the sleeve 2 falling off during the process of moving and approaching the throttling tube. The sleeve 2 is connected to the screw 1 through the limiting component 4, thereby limiting the screw 1 in the length direction of the sleeve 2 and reducing the possibility of the screw 1 detaching from the end of the sleeve 2 near the fixed rod 21.

[0040] Reference Figure 3 The limiting component 4 includes a limiting ring 41 that is sleeved on the outside of the screw 1 and fixedly connected to the screw 1. The limiting ring 41 is located in the sleeve 2 and its diameter is larger than the inner diameter of the sleeve 2. A movable groove 24 is provided on the inner side wall of the sleeve 2, which is adapted to the limiting ring 41 and is arranged along the length direction of the sleeve 2. The limiting ring 41 is inserted into the movable groove 24 and is slidably and rotatably connected to the sleeve 2 through the movable groove 24.

[0041] Two springs 42 are provided on the side of the limiting ring 41 away from the limiting rod 11, which are arranged along the length of the sleeve 2 and located in the moving groove 24. The springs 42 are symmetrically arranged on both sides of the rotation axis of the sleeve 2, and the end of the spring 42 away from the limiting rod 11 is fixedly connected to the inner wall of the sleeve 2.

[0042] A contact ring 43, parallel to the limiting ring 41 and inserted into the moving groove 24, is fixedly connected to one end of the spring 42 near the limiting ring 41. The contact ring 43 is sleeved on the screw 1. Multiple balls 44 are mounted on the side of the limiting ring 41 near the contact ring 43, with the sidewalls of the balls 44 contacting the sidewalls of the contact ring 43. When the spring 42 is at its original length, the limiting ring 41 is located at the end of the moving groove 24 near the fixed rod 21.

[0043] When the throttling tube is installed through the screw 1, the limiting ring 41 slides and rotates with the sleeve 2 through the moving groove 24. At this time, the spring 42 is compressed. After the screw 1 is reversed and disengaged from the throttling tube, the spring 42 restores its deformation and pushes the screw 1 to reset, reducing the possibility of the screw 1 falling out of the sleeve 2.

[0044] Spring 42 contacts limit ring 41 through contact ring 43, reducing the possibility that the end of spring 42 may hinder the rotation of limit ring 41. Ball 44 reduces the friction force generated between limit ring 41 and the side wall of contact ring 43 when it rotates, further facilitating the drive screw 1 to install the throttle tube on the throttle tube seat.

[0045] An electromagnet block 5 is installed inside the end of the screw 1 furthest from the limiting rod 11. A receiving cavity 12 is formed inside the screw 1, and the electromagnet block 5 is located in the receiving cavity 12 and fixedly connected to the inner wall of the screw 1. When the throttling tube is installed on the screw 1, the electromagnet block 5 is energized to improve the stability of the installation between the throttling tube and the screw 1, reducing the possibility of relative movement of the throttling tube along the length of the screw 1 when installing it by rotating the screw 1. After installation, the electromagnet block 5 is de-energized to facilitate the removal of the screw 1 from the throttling tube.

[0046] The implementation principle of Example 2 is as follows: When the throttling tube is installed by the screw 1, the limiting ring 41 slides and rotates with the sleeve 2 through the moving groove 24. At this time, the spring 42 is compressed. After the screw 1 is reversed and disengaged from the throttling tube, the spring 42 restores its deformation and pushes the screw 1 to reset, reducing the possibility of the screw 1 falling out of the sleeve 2.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
