Abstract
The utility model discloses a kind of modified wheel stand round nut four paws sleeve, solve the problem of the claw easy fracture in existing round nut four paws sleeve, the claw of this modified wheel stand round nut four paws sleeve is changed a social system by the straight shape claw on existing round nut four paws sleeve and is become L shape claw, and the boss on described L shape claw and the ring-shaped groove on described round nut match.A kind of modified wheel stand of the utility model round nut four paws sleeve, it can export larger moment of torsion, and energy is dismounting wheel stand round nut reliably, has practical, the features such as result of use is good.
Description
Technical field
The utility model relates to a kind of modified wheel stand round nut four paws sleeve, belongs to maintenance tool field, especially relates to the improvement of Mining cart torque-converters wheel stand round nut four paws sleeve.
Background technology
Torque-converters wheel stand round nut 10 as shown in Figure 1, its upper end is provided with ring-shaped groove 11, outer peripheral sidewall is provided with four uniform rectangular channels 12, described round nut 10 is arranged in bore, gap between its outer peripheral sidewall and bore inwall is less than 1 millimeter, be existing four paws sleeve 20 as shown in Figure 2, its upper end is shaped with four straight shape claws 21, can to insert in rectangular channel on round nut 10 12 (as shown in Figure 3) for tightening or loosening round nut 10.Because the cross-sectional area of straight shape claw 21 is little, if excessive with the moment of torsion of four paws sleeve 20 slewing circle nut 10 time, the root 22 of straight shape claw 21 is subject to excessive shearing force and often can ruptures, and causing cannot dismounting wheel stand round nut, causes the maintenance of equipment to be affected.
Summary of the invention
The purpose of this utility model is just to provide a kind of modified wheel stand round nut four paws sleeve, and it can the round nut of effective dismounting torque-converters wheel stand.
The technical scheme that the utility model adopts is: a kind of modified wheel stand round nut four paws sleeve, the claw of this modified wheel stand round nut four paws sleeve is changed a social system by the straight shape claw on existing round nut four paws sleeve and is become L shape claw, and the boss on described L shape claw and the ring-shaped groove on described round nut match.
A kind of modified wheel stand round nut four paws sleeve of the present utility model, it can export larger moment of torsion, and energy is dismounting wheel stand round nut reliably, has practical, the features such as result of use is good.

Fig. 2 is the stereogram of existing round nut four paws tube-in-tube structure schematic diagram.
Fig. 3 is the partial sectional view of Fig. 2 four paws sleeve when inserting Fig. 1 round nut rectangular channel.
Fig. 4 is the stereogram of the utility model structural representation.
Fig. 5 is the partial sectional view of Fig. 4 four paws sleeve when inserting Fig. 1 round nut rectangular channel.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
As shown in Figures 1 to 5, a kind of modified wheel stand of the utility model round nut four paws sleeve, the claw of this modified wheel stand round nut four paws sleeve 30 is changed a social system by the straight shape claw 21 on existing round nut four paws sleeve 20 and is become L shape claw 31, and the boss 33 on described L shape claw 31 matches with the ring-shaped groove 11 on described round nut 10.
Because the cross-sectional area of the root 32 of L shape claw 31 is larger than the cross-sectional area of straight shape claw 21 root 22, its shearing force of bearing is larger, and the moment of torsion thus tightening or loosening round nut 10 also can be larger.
Claims (1)
1. a modified wheel stand round nut four paws sleeve, it is characterized in that: the claw of this modified wheel stand round nut four paws sleeve (30) becomes L shape claw (31) by straight shape claw (21) transformation of the way on existing round nut four paws sleeve (20), and the boss (33) on described L shape claw (31) matches with the ring-shaped groove (11) on described round nut (10).
