Abstract
The utility model discloses an adjustable spanner suitable for a round nut with an end surface pinhole or a lateral surface pinhole. A guiding groove is arranged on the front lateral surface of a short arm of a T-shaped hand-hold handle, two guiding bars are respectively installed in the groove arranged at both sides, the guiding bars are respectively matched with an adjustable leading screw, the right and the left thread of which rotate oppositely, both ends of the adjustable leading screw are respectively installed on the front lateral surface of the short arm of the T-shaped hand-hold handle through an end cover, thereby forming a running fit with the end cover, guiding grooves are evenly arranged at the extending direction of the two guiding bars, pin claw seats which can be moved in the guiding grooves and can be vertically matched with the guiding grooves are installed in the grooves, knurled nuts of the pin claw seats can be locked at any position of the guiding grooves of the guiding bars, and detachable pin claws are evenly installed at the front ends and on the inner lateral surfaces of the pin claw seats. The distance between the pin claws is adjusted, to be applied to the rotary twisting of round nuts of different specifications of the outer diameter; in addition, the pin claws and the pin claw seats are coupled both at horizontal and vertical directions, thus the adjustable spanner is not only suitable for the rotary twisting of the round nuts with the end surface pinholes, but also suitable for the rotary twisting of the round nuts with the lateral surface pinholes.
Description
Technical field
The utility model relates to the round nut spanner, especially relates to a kind of round nut adjustable spanner with end face or side surface pin-hole that is applicable to.
Background technology
Round nut has two kinds of different specifications at present, and a kind of is the form that the side has groove, and another kind is the form that side or end face have pin-and-hole.For the round nut of preceding a kind of specification, the existing a variety of spanners that turn.For the round nut of a kind of specification in back, representative spanner has two kinds at present: [Haier Group, Co. the spanner of the round nut of band edge face pin-and-hole; Chinese patent 99202747.0] designed a kind of end face pin-and-hole round nut spanner, can realize the feed-through installation.But two of this spanner pin pawls are fixed, and can only realize screwing of round nut that the model specification that matches is fixing; [Zhao Liping. adjustable round nut spanner. Chinese patent .200520116631.6] designed a kind of adjustable round nut, an end of spanner both arms is articulated by articulated part and connects, and the other end is provided with two pin pawls.Though the both arms of this spanner can rotate around articulated part, thereby change the distance of two pins between pawls to adapt to the round nut of different size external diameter; But when this spanner turned the round nut that is used for the feed-through connection, the both arms of spanner outer arm easy and feed-through was interfered.
Summary of the invention
In order to overcome existing unadjustable round nut spanner or can to regulate but the deficiency that can occur interfering when turning the round nut of big external diameter specification, the purpose of this utility model is to provide a kind of round nut adjustable spanner with end face or side surface pin-hole that is applicable to.
The technical scheme that its technical problem that solves the utility model adopts is:
Have gathering sill at T shape hand holding handle galianconism leading flank, in two side channels of gathering sill gib block is housed respectively, the adjusting leading screw that gib block is opposite with left and right sides thread rotary orientation respectively matches, the two ends of regulating leading screw are installed in T shape hand holding handle galianconism leading flank with end cap respectively, be rotatably assorted with end cap formation, on the bearing of trend of two gib blocks, all have gathering sill, be equipped with in the gathering sill and can in gathering sill, move, and with the perpendicular pin pawl seat that cooperates of gathering sill, pin pawl seat can be locked on the gathering sill optional position of gib block, and pin pawl seat front end and medial surface all are equipped with the pin pawl that can dismantle.
The beneficial effect that the utlity model has is:
The distance of pin between pawl can and be regulated leading screw by gib block and be changed within the specific limits, thereby is applied to the screwing of round nut of various outer diameter specification; In addition, pin pawl and pin pawl seat can be chosen in level and vertically connect on the both direction, feasiblely both have been applicable to screwing of round nut with end face pin-and-hole, also are applicable to screwing of round nut with side surface pin-hole.
Description of drawings
Fig. 1 is an integral installation figure of the present utility model.
Fig. 2 is the explosive view of the utility model integral installation figure.
Fig. 3 is the enforcement illustration that the utility model is used to have the round nut of end face pin-and-hole.
Fig. 4 is that the utility model is used to the enforcement illustration with the round nut of side surface pin-hole.
Among the figure: 1.T shape hand holding handle, 2. regulate leading screw, 3. gib block, 4. end cap, 5. annular knurl round nut, 6. pin pawl, 7. pin pawl seat, 8. trip bolt, 9. round nut, 10. connected piece, 11. bases.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, shown in Figure 2, the utility model has gathering sill at T shape hand holding handle 1 galianconism leading flank, in two side channels of gathering sill gib block 3 is housed respectively, the adjusting leading screw 2 that gib block 3 is opposite with left and right sides thread rotary orientation respectively matches, the two ends of regulating leading screw 2 are installed in T shape hand holding handle 1 galianconism leading flank with end cap 4 respectively, with trip bolt 8 lockings, two ends and end cap 2 formation of regulating leading screw 2 are rotatably assorted, on the bearing of trend of two gib blocks 3, all have gathering sill, be equipped with in the gathering sill and can in gathering sill, move, and with the perpendicular pin pawl seat 7 that cooperates of gathering sill, pin pawl seat 7 usefulness annular knurl round nuts 5 can be locked on the gathering sill optional position of gib block 3, and pin pawl seat 7 front ends and medial surface all are equipped with the pin pawl 2 that can dismantle.
As shown in Figure 1 and Figure 2, pin pawl 6 can be by front end that is screwed at pin pawl seat 7 or the inboard of selling pawl seat 7.Pin pawl seat 7 is fixed in the gib block 3 by annular knurl round nut 5, and pin pawl seat 7 can slide along gib block 3.Two gib blocks 3 respectively by about revolve screw thread and regulate leading screw 2 and connect, the assembly of formation is assemblied in the gathering sill of T shape hand holding handle 1, the bottom surface of gib block 3 contacts with the bottom surface of groove.Regulate the part that is used to rotate in the middle of the leading screw 2 and control into knurling.The concrete use is that when turning clockwise leading screw 2, two gib blocks 3 are close; On the contrary, be rotated counterclockwise when regulating leading screw 2, two gib blocks 3 away from.The distance adjustment scope that two gib blocks are 3 equates with pin pawl seat 7 sliding distance scope in gib block 3.Regulate leading screw 2 and be rotatably assorted, end cap 4 is fixed on the T shape hand holding handle 1 with trip bolt 8 with the lateral aperture that T shape hand holding handle 1 and two end cap 4 form.
