Description
Technical field
This utility model relates to multi-claw spanner technical field, particularly relates to the two-way multi-claw spanner of a kind of port lid.
Background technology
The port lid of some products is installed relatively tight, needs again port lid to tighten after having inspected by random samples. Port lid external diameter is about 150mm, is difficult to find pipe wrench or the spanner of such mouth of tongs during sampling observation, generally knocks by instruments such as bottle openers and just can open (tightening), the skidding time-consuming, easy and easily cause port lid surface damage of requiring great effort. Therefore, work out a kind of spanner that can conveniently open and tighten large-scale port lid to have great importance.
Utility model content
This utility model is for the deficiencies in the prior art, it is provided that the two-way multi-claw spanner of a kind of port lid.
The technical solution of the utility model is as follows: the two-way multi-claw spanner of a kind of port lid, including upper junction plate, lower connecting plate, central gear and finger gear, described central gear is arranged between upper junction plate and lower connecting plate, the rotating shaft of central gear is positioned at the center of upper junction plate or lower connecting plate, the periphery of central gear is uniformly distributed N number of finger gear, central gear and finger gear mesh together, and N is 3 or 4.
Described central gear is respectively provided on two sides with upper and lower round boss up and down, upper and lower round boss is inlaid in the center hole of upper junction plate and lower connecting plate respectively, the upper round boss face of central gear is concordant with upper junction plate upper surface, and in the middle part of upper round boss opening square hole, connect adapter.
Finger gear is fixed between upper junction plate and lower connecting plate by the gear center hole of turnbuckle and finger gear by screw; Turnbuckle is sandwiched between upper junction plate and lower connecting plate, and turnbuckle endoporus is by screw through fixing, and cylindrical coordinates with the gear center hole of finger gear.
Described finger gear is L-type, including the gear connected as one and hock.
Being cased with Anti-slip cover on the hock of described finger gear, material is the nonmetallic materials such as silica gel or nylon, and Anti-slip cover can increase hock pawl and hold the friction of port lid, can also avoid the loss that tooth is grabbed simultaneously.
Described N number of finger gear even circumferential distribution, mutual angle is 360 °/N, and N number of finger gear even circumferential is distributed, it is ensured that finger gear uniform force, it is easier to open port lid.
In the two-way multi-claw spanner use procedure of port lid, dual-purpose for L-type handle is inserted adapter and rotates;The dual-purpose handle two ends of L-type can be inserted into adapter, it is possible to is suitable for different spaces and torque requirement.
The grasping radius that the hock of three finger gears of this utility model is formed automatically adjusts within the scope of grasping, it is possible to suitable in the dismounting of different size port lid. It has the two-way multi-claw spanner dismounting port lid efficiency height of port lid, saving time and muscle power, the advantage not resulting in port lid surface damage.
Provide the benefit that: this utility model simple in construction, make easily, cost low, by the mode that gear engages, indirectly achieve hock firmly grasping and rotating port lid, and, owing to the grasping radius of 3 or 4 hock formation can freely regulate, therefore, the dismounting of different size port lid it is applicable to.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further details.
Embodiment 1
As shown in Figure 1 and Figure 2, the two-way multi-claw spanner of described port lid includes upper junction plate 7, lower connection 4 plate, central gear 3 and finger gear 2, central gear 7 is arranged between upper junction plate 7 and lower connecting plate 4, central gear about 3 both sides have upper round boss and lower round boss respectively, upper round boss is inlaid in upper junction plate 7 center hole, lower round boss is inlaid in lower connecting plate 4 center hole, and the periphery of central gear 3 is uniformly distributed 3 finger gears, and meshes together; Each finger gear includes the gear and the hock that link together, gear and hock are structure as a whole, the upper round boss of central gear 3 is inlaid in upper junction plate 7 center hole, make round boss face concordant with upper junction plate 7 upper surface, and in the middle part of upper round boss opening square hole, connect adapter 8; L-type dual-purpose handle 10 two can be inserted into adapter 8, is suitable for different spaces and torque requirement;
Described finger gear 2 is L-type, and when production and processing, gear is one-body molded with hock; Anti-slip cover 1 is enclosed within the hock of finger gear 2; 3 finger gears 2 are circumferentially uniform, and mutual angle is 120 °; Finger gear 2 is fixed between upper junction plate 7 and lower connecting plate 4 by the gear center hole of turnbuckle 5 and finger gear 2 by screw 6; Turnbuckle 5 is sandwiched between upper junction plate and lower connecting plate, and turnbuckle 5 endoporus is by screw 6 through fixing, and cylindrical coordinates with the gear center hole of finger gear 2.
Working method of the present utility model is: the hock pawl of finger gear 2 holds port lid, adapter 8 connects the dual-purpose handle 10 of L-type, rotating the dual-purpose handle 10 of L-type, adapter 8 rotates, and drives central gear 3 to rotate, and drive the hock of three finger gears 2 simultaneously and rotating in same direction, now, the rotation direction of adapter 8 can according to actual needs, be changed, and then adjustment hock opens or tightens up, it is achieved firmly grasping and rotation of different-diameter port lid.
Embodiment 2
The two-way multi-claw spanner of port lid that this utility model provides also has a kind of way of realization. The difference is that, this two-way multi-claw spanner has 4 finger gears, as it is shown on figure 3, the advantage adopting 4 finger gears is to increase
Contact area, it is provided that bigger chucking power;Working method multi-claw spanner two-way with the port lid of 3 finger gears is identical.
