Detailed Description
Embodiments of the present utility model are described in detail below with reference to fig. 1-4.
The utility model provides a no spoke wheel circle is from centering struts anchor clamps, includes disk body 1, and driving motor 17 is installed to disk body 1 inboard intermediate position, is connected with drive bevel gear 18 on driving motor 17's the motor shaft, has seted up at least three guide way 2 on the disk body 1, and guide way 2 below all is provided with lead screw 20, and the inner of lead screw 20 is connected with driven bevel gear 19, and each driven bevel gear 19 all meshes with the drive bevel gear 18 in the centre. The screw rod 20 is provided with a movable block 3, the movable block 3 is fixedly provided with a fixed block 4 through a first fixing bolt 11, and the fixed block 4 passes through the guide groove 2 to be connected with the movable block 3. The outer end of the fixed block 4 is connected with a mounting block 5, an arc-shaped block 6 is welded on the upper portion of the mounting block 5, a backboard 7 is connected on the upper portion of the arc-shaped block 6, and an abutting block 8 is detachably mounted on the backboard 7.
The driving motor 17 drives the bevel gear 18 to rotate, and the driving bevel gear 18 drives the meshed driven bevel gear 19 to rotate. The driven bevel gear 19 drives the screw rod 20 to rotate so as to control the movable block 3 to move. The movable block 3 drives the fixed block 4 to move along the guide groove 2, so that the abutting block 8 on the arc-shaped block 6 is driven to move outwards, and the abutting block 8 abuts against the inner side of the rim to fix the rim. Since the movements of the abutment blocks 8 are synchronized, an automatic centering of the rim can be achieved.
According to the inside shape of different rims, select supporting butt piece 8 to install on backplate 7 to make butt piece 8 can laminate the inboard of rim in order to support tightly, guarantee fixed firmness, avoid becoming flexible.
The backboard 7 is provided with a slot 12, and the abutting block 8 is provided with a clamping block 13 matched with the slot 12. When the abutting block 8 is mounted on the back plate 7, the clamping block 13 is only required to be aligned with the slot 12 for insertion. Since the movement direction of the abutment block 8 is perpendicular to the insertion direction of the clip 13, the abutment block 8 is generally not displaced when the rim is fixed.
In order to reduce the accidental generation of the displacement of the abutting block 8, after the clamping block 13 is inserted into the slot 12, the pressing plate 15 is covered outside the slot 12, and the pressing plate 15 is fixed by screwing the second fixing bolt 16 into the second threaded hole 14 through the pressing plate 15, so that the clamping block 13 is fixed in the slot 12, and the clamping block 13 cannot slide in the slot 12 to enable the abutting block 8 to displace.
The fixed block 4 is provided with a through hole 9, the upper part of the movable block 3 is provided with a first threaded hole 10, and a first fixing bolt 11 is screwed into the first threaded hole 10 through the through hole 9, so that the fixed block 4 is fixed on the movable block 3.
A rotating seat 21 is arranged in the disc body 1, and a screw rod 20 is rotatably arranged on the rotating seat 21. The rotating seat 21 is also connected with a guide rod 22, the guide rod 22 penetrates through the movable block 3, and the guide rod 22 is used for guiding the movement of the movable block 3.
The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
