[0002] A mechanical connection sleeve for steel bars is a mechanical device used for connecting steel bars, which is widely used in construction and civil engineering. It connects steel bars together mechanically to ensure the strength and stability of the connection.
[0003] For example, the Chinese patent discloses: a new type of mechanical connection sleeve for steel bars, patent number: CN217998627U, which forms a larger axial adjustment gap of the thread pair through three pairs of mating threads, greatly increasing the probability of the coincidence of the spiral trajectories and making the connection of steel bars very convenient and fast.
[0004] However, in the implementation of the above technical solution, it is found that there are at least the following technical problems: the above device connects the steel bars by screwing them into the sleeve, but the above device lacks an auxiliary support function. To ensure the bearing capacity, the staff needs to spend extra time and energy to adjust the perpendicularity of the steel bars when screwing the steel bars, reducing the construction efficiency and prolonging the construction time. Summary of the Utility Model
[0005] (1) Technical Problems to be Solved
[0006] In view of the deficiencies of the prior art, the utility model provides a mechanical connection sleeve for steel bars, which solves the technical problems that the above device connects the steel bars by screwing them into the sleeve, but the above device lacks an auxiliary support function. To ensure the bearing capacity, the staff needs to spend extra time and energy to adjust the perpendicularity of the steel bars when screwing the steel bars, reducing the construction efficiency and prolonging the construction time.

Specific implementation mode
[0024] In the embodiment of the present application, by providing a mechanical connection sleeve for steel bars, the above-mentioned device effectively solves the problem that the above-mentioned device lacks an auxiliary support function when connecting steel bars by screwing the steel bars into the sleeve. To ensure the bearing capacity, the staff needs to spend extra time and energy to adjust the verticality of the steel bars when screwing the steel bars, which reduces the construction efficiency and prolongs the construction time. Before screwing the steel bar body, the support ring can be pulled outwards by holding the handle. After the support ring slides out, the clamping block loses the force of being squeezed by the sleeve body. At this time, under the action of the spring, the clamping block is driven to slide outwards. When screwing and connecting the steel bar body, the clamping block is in contact with the outer surface of the steel bar body to ensure the verticality of the steel bar body during connection, without spending extra time and energy to adjust the verticality of the steel bar body, which is beneficial to improving work efficiency and reducing connection errors caused by the skew of the steel bar body, ensuring the stability and firmness of the connection.

To ensure the bearing capacity, the staff needs to spend extra time and energy to adjust the verticality of the steel bars when screwing the steel bars, which reduces the construction efficiency and prolongs the construction time. The general idea is as follows: A mechanical connection sleeve for steel bars includes a sleeve body 11. A chute 12 is provided inside the sleeve body 11. A support ring 13 is slidably connected inside the chute 12. A rectangular groove 14 is provided inside the support ring 13. A spring 15 is fixedly connected to the inner surface of the rectangular groove 14. A clamping block 16 is fixedly connected to the outer surface of the spring 15. The clamping block 16 is slidably connected inside the rectangular groove 14. A support mechanism is fixedly connected to the outer surface of the support ring 13. The support mechanism includes a handle 17. The handle 17 is fixedly connected to the outer surface of the support ring 13. A steel bar body 18 is threadedly connected inside the sleeve body 11. The two steel bar bodies 18 are respectively screwed into the sleeve body 11, and the two steel bar bodies 18 are connected together through the sleeve body 11 to ensure the strength and stability of the connection. Before screwing the steel bar body 18, the support ring 13 can be pulled outwards by holding the handle 17. After the support ring 13 slides out, the clamping block 16 loses the force of being extruded by the sleeve body 11. At this time, the clamping block 16 is driven to slide outwards under the action of the spring 15. When screwing and connecting the steel bar body 18, the clamping block 16 is attached to the outer surface of the steel bar body 18 to ensure the verticality of the steel bar body 18 during connection, without spending extra time and energy to adjust the verticality of the steel bar body 18, which is beneficial to improving work efficiency and reducing connection errors caused by the skew of the steel bar body 18, and ensuring the stability and firmness of the connection.
[0027] The steel bar body 18 and the clamping block 16 are adapted to each other. A first clamping block 19 is fixedly connected to the outer surface of the sleeve body 11. A first connecting block 21 is fixedly connected to the outer surface of the sleeve body 11. A clamping groove 22 is provided inside the first connecting block 21. A second clamping block 23 is clamped inside the clamping groove 22. A retaining cover 24 is fixedly connected to the inner surface of the second clamping block 23.

[0029] Aiming at the problems existing in the prior art, the utility model provides a steel bar mechanical connection sleeve. Before screwing the steel bar body 18, the support ring 13 can be pulled outwards by holding the handle 17. After the support ring 13 slides out, the clamping block 16 loses the force of being squeezed by the sleeve body 11. At this time, the spring 15 drives the clamping block 16 to slide outwards. When screwing and connecting the steel bar body 18, the clamping block 16 fits against the outer surface of the steel bar body 18 to ensure the perpendicularity of the steel bar body 18 during connection, without spending extra time and effort to adjust the perpendicularity of the steel bar body 18, which is beneficial to improving work efficiency and reducing connection errors caused by the skew of the steel bar body 18, ensuring the stability and firmness of the connection.
[0030] Working principle:
[0031] First step, screw the two steel bar bodies 18 into the sleeve body 11 respectively, and connect the two steel bar bodies 18 together through the sleeve body 11 to ensure the connection strength and stability. Before screwing the steel bar body 18, the support ring 13 can be pulled outwards by holding the handle 17. After the support ring 13 slides out, the clamping block 16 loses the force of being squeezed by the sleeve body 11. At this time, the spring 15 drives the clamping block 16 to slide outwards. When screwing and connecting the steel bar body 18, the clamping block 16 fits against the outer surface of the steel bar body 18 to ensure the perpendicularity of the steel bar body 18 during connection, without spending extra time and effort to adjust the perpendicularity of the steel bar body 18, which is beneficial to improving work efficiency and reducing connection errors caused by the skew of the steel bar body 18, ensuring the stability and firmness of the connection.
[0032] Second step, after the screwing connection of the steel bar body 18 is completed, the retaining cover 24 is sleeved on the outer surface of the steel bar body 18. The retaining cover 24 slides down and fits with the outer surface of the sleeve body 11. Align the second connecting block 26 outside the retaining cover 24 with one side of the first clamping block 19 on the outer surface of the sleeve body 11. Then screw the retaining cover 24. The first clamping block 19 is clamped into the clamping groove 22 formed in the second connecting block 26 to fixedly connect the retaining cover 24 and the sleeve body 11 together. The connection between the steel bar body 18 and the sleeve body 11 is shielded and protected by the retaining cover 24. The sealing ring 25 connected inside the retaining cover 24 fits with the steel bar body 18 to seal the connection, preventing external environmental factors such as rainwater and moisture from entering the connection and causing rust, thereby extending the service life of the device.
