Description

Technical Field

[0001] The utility model relates to the technical field of fixing rings, in particular to a fixing ring with a quick handle locking type. Background Art

[0002] A fixing ring is a workpiece used for internal fixing of a bearing. It can be used with other parts, such as a fixing plate, a sensor, etc. by being arranged in a mounting hole.

[0003] In the existing design of the grooved fixing ring, a circular main body structure is adopted, and a series of grooves are provided on the ring body to increase the friction with the mounting surface and improve the fixing effect. At the same time, through holes and threaded holes are provided on both sides of the grooves. The through holes are used for passing bolts, and the threaded holes are used for screwing in nuts or bolt heads for fastening. Due to the structural limitation of the fixing ring, when the bolt is tightened, the lever arm acting on the fixing ring is relatively short. In the case of the fixing ring, the length of the lever arm will affect the magnitude of the clamping force generated when the bolt is tightened. Due to the short lever arm, in order to achieve sufficient clamping force, a greater tightening force needs to be applied, which may cause the bolt to be overstressed, even damage the thread, and reduce the overall structural stability and service life.

[0004] Therefore, it is necessary to design a fixing ring with a quick handle locking type with a longer lever arm. Summary of the Utility Model

[0005] In order to overcome the disadvantage that the fixing ring needs a very large force of the bolt to clamp it, the technical problem of the utility model is to provide a fixing ring with a quick handle locking type with a long lever arm and easy locking.

[0006] The technical implementation scheme of the utility model is: a fixing ring with a quick handle locking type, a nozzle-shaped fixing ring; a screw rod, the screw rod is penetrated and arranged on the nozzle-shaped fixing ring; a thin nut, the thin nut is threadedly connected to the screw rod; further comprising: a pin, the pin is rotatably connected to the screw rod; a handle, the handle is penetrated and connected to the pin.

[0007] Furthermore, a toothed cylinder, the toothed cylinder is arranged on the handle; a fixing frame, the fixing frame is arranged on one side of the nozzle-shaped fixing ring; a rack, the rack is rotatably connected to the fixing frame; a torsion spring, the torsion spring is sleeved on the fixing frame.

[0008] Furthermore, it further comprises: a connecting column, the connecting column is arranged on the pin; a knob, the knob is arranged on the connecting column; a knob sleeve, the knob sleeve is threadedly connected to the knob; a wedge-shaped pressing strip, the wedge-shaped pressing strip is arranged inside the knob sleeve.

[0009] Further, it also includes: a rubber pad, and the rubber pad is arranged inside the pouting mouth-shaped fixing ring.

[0010] Further, it also includes: a pressing ring, and the pressing ring is placed between the pouting mouth-shaped fixing ring and the thin nut.

[0011] Further, it also includes: a protective pad is arranged on the handle.

[0012] Further, it also includes: a pull handle, and the pull handle is arranged on the rack.

[0013] The utility model has the following advantages: 1. By rotating the handle and driving the pouting mouth-shaped fixing ring to extrude, the workpiece can be locked, so that the fixing ring can be quickly locked and loosened without rotating the handle, which is more convenient and faster than the bolt-type clamping structure.

[0014] 2.

DETAILED DESCRIPTION OF THE INVENTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1: A type with a quick handle locking for a fixing ring. Refer to Figures 1-4 and Figure 6 As shown, it includes: a nozzle-shaped fixing ring 1, a screw rod 2, a thin nut 3, a handle 4, and a pin 5. The front end of the nozzle-shaped fixing ring 1 is penetrated by the screw rod 2, and a thin nut 3 for limiting is threadedly arranged on the screw rod 2. The top of the screw rod 2 is penetrated by the pin 5, and the handle 4 is penetrated by the pin 5. A protective pad is provided on the handle 4.

[0024] The nozzle-shaped fixing ring 1 is in a contracted state when locked. When the fixing ring is needed, first pull the handle 4 outwards to unlock. Pulling the handle 4 outwards causes the nozzle-shaped fixing ring 1 to expand outwards, making the nozzle-shaped fixing ring 1 in a normal state. Subsequently, dock the workpiece to be locked with the inner hole of the nozzle-shaped fixing ring 1, and then press the handle 4 downwards. The handle 4 rotates, and the screw rod 2 plays a guiding role. When the handle 4 is pressed downwards, it squeezes the nozzle-shaped fixing ring 1, causing the nozzle-shaped fixing ring 1 to deform. The deformation of the nozzle-shaped fixing ring 1 squeezes the workpiece. After locking, the clamping force of the nozzle-shaped fixing ring 1 is greater, preventing the workpiece from falling off the nozzle-shaped fixing ring 1. At the same time, the nozzle-shaped fixing ring 1 is easier to lock, and the workpiece can be quickly locked.

[0025] Embodiment 2: On the basis of Embodiment 1, refer to Figure 4 and Figure 5 As shown, it further includes: a toothed cylinder 6, a fixing bracket 7, a rack 8, a pull handle 9, and a torsion spring 10. A toothed cylinder 6 is arranged on one side of the handle 4. A fixing bracket 7 is arranged on the nozzle-shaped fixing ring 1. A rack 8 for limiting the toothed cylinder 6 is arranged on the fixing bracket 7. A pull handle 9 is arranged at the top of the rack 8. A torsion spring 10 is sleeved on the fixing bracket 7, and one end of the torsion spring (10) is connected to the rack (8).

[0026] To prevent the handle 4 from shaking during use and causing the pouting-type fixing ring 1 to be accidentally unlocked, first pull the pull handle 9. Pulling the pull handle 9 rotates the rack 8. When the rack 8 rotates, the torsion spring 10 deforms. The tooth cylinder 6 will disengage from the rack 8. When the handle 4 is rotated, the tooth cylinder 6 will engage with the rack 8 for positioning, preventing the pouting-type fixing ring 1 from being accidentally unlocked when shaking. When unlocking is required, just release the pull handle 9. Under the reset action of the torsion spring 10, the rack 8 is driven to reset, so that the rack 8 engages with the tooth cylinder 6 again, and the handle 4 can be fixed, thereby increasing the stability of the handle 4.

[0027] Refer to Figure 6 And Figure 7 As shown, it further includes: a connecting column 11, a knob 12, a knob sleeve 13 and a wedge-shaped pressing strip 1301. One end of the bolt 5 is provided with a connecting column 11. A knob 12 is provided on the connecting column 11. A knob sleeve 13 is connected to the knob 12 by a thread. A wedge-shaped pressing strip 1301 for clamping the knob 12 is arranged inside the knob sleeve 13, and one end of the wedge-shaped pressing strip (1301) is clamped with the inside of the knob (12).

[0028] To prevent the bolt 5 and the handle 4 from disengaging due to shaking during locking, resulting in the unlocking of the pouting-type fixing ring 1, rotate the knob sleeve 13 to contact the knob 12. When the knob sleeve 13 is installed, the wedge-shaped pressing strip 1301 is clamped with the knob 12. When the wedge-shaped pressing strip 1301 is squeezed, it deforms. The wedge-shaped pressing strip 1301 is clamped between the connecting column 11 and the knob 12 to stabilize the bolt 5, and the bolt 5 will not shake and disengage. When replacing or repairing the workpiece, only need to rotate the knob sleeve 13. When the knob sleeve 13 rotates, the wedge-shaped pressing strip 1301 disengages from the knob 12, and then the knob sleeve 13 is rotated out, and the bolt 5 can be removed from the handle 4.

[0029] It further includes: a rubber pad 14. A rubber pad 14 is arranged inside the pouting-type fixing ring 1, and the rubber pad 14 can further stabilize the workpiece to be locked.

[0030] It further includes: a pressing ring 15. A pressing ring 15 is placed between the pouting-type fixing ring 1 and the thin nut 3. The pressing ring 15 is used to protect the pouting-type fixing ring 1 and the thin nut 3, preventing friction during extrusion and reducing the service life of the thin nut 3.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
