Description
Technical field
The present invention relates to a kind of installation utensil, be specifically related to a kind of circular spanner.
Background technology
Existing functions of wrench is single, usually Automatic manual transmission, maintenance, safeguard time to use the spanner of plurality of specifications, use, carry all inconvenient, and easily to lose.Existing spanner is inconvenient to regulate, and is generally only suitable for the handling of a kind of nut or bolt, carries and uses all inconvenient, nor can be used for handling tubulars.
In order to solve the problems of the technologies described above, Chinese patent CN20282564 discloses a kind of circular spanner, comprise handle and circular shaped motion head, circular shaped motion head is provided with arc-shaped notch, the wall of arc-shaped notch is provided with anti-slip veins, circular shaped motion head is also provided with pilot hole and hole clipping, handle front end is provided with fan-shaped gland, fan-shaped gland plugging in fitting hole, be placed in arc-shaped notch, handle is also provided with slotted eye, the cell wall of slotted eye is provided with screw thread, threaded rod embeds slotted eye and the hole clipping connected on circular shaped motion head, threaded rod movement in slotted eye can drive movable head opposite handle to move.
But also there is following technological deficiency in above-mentioned patented technology: described anti-slip veins belongs to friction projection, drive described nut or bolt to rotate by the frictional force produced with nut, bolt close contact, thus coordinate the object of installation, dismounting nut or bolt.The surface of described nut or bolt can scratch by such operation, is unfavorable for that next time installs and disassembling section.
Summary of the invention
The invention is intended to provide a kind of circular spanner not easily bolt or nut scratched.
Circular spanner in this programme, comprises handle and hollow sleeve, and be provided with a Hexagonal jacket in described hollow sleeve, described Hexagonal jacket be installed with a gear, described gear overlaps with the axis of Hexagonal jacket, and described Hexagonal jacket passes described hollow sleeve; Be provided with between described handle and hollow sleeve and refute the portion of connecing, described in refute in the portion of connecing and be hinged with two poles of getting involved in respectively in hollow sleeve middle gear teeth groove, described in refute the back-moving spring being also provided with in the portion of connecing and two poles being gathered; Be provided with the corner block for limiting angle between two poles between two poles, described corner block is hinged on refutes in the portion of connecing.
Adopt technical scheme of the present invention, there is following technique effect:
On hex nut Hexagonal jacket being nested into form fit and hex bolts, then just can rotate Hexagonal jacket by handle, realize screwing and unscrewing of hex nut or bolt, and can not scratching bolt or nut.
Intervention additionally by a pole pair teeth groove realizes regulating gear and the degree of tightness of refuting between the portion of connecing, only have when two between pole and gear (under the effects at back-moving spring and corner block) cannot relative motion time, described handle just comes rotating bolt and nut by Hexagonal jacket.
Further, be provided with shoulder in described hollow sleeve, described Hexagonal jacket passes the middle part of shoulder, is also provided with pad and circumferential band in described hollow sleeve, described circumferential band is fastened between described pad and hollow sleeve inwall, and described gear is folded between described pad and shoulder.
In order to avoid described Hexagonal jacket jumps in described hollow sleeve, spy arranges shoulder, pad and circumferential band, carries out spacing up and down to Hexagonal jacket and gear.
Further, described in refute the portion of connecing and be provided with a rotating shaft, one end of described corner block is fixed in described rotating shaft, described in refute the portion upper surface of connecing a connecting rod be installed, one end and the rotating shaft of described connecting rod are hinged, and the other end of connecting rod is hinged on refutes the portion of connecing.
The Main Function of described connecting rod is indicative function, when described connecting rod and refute no longer to there is relative motion between the portion of connecing time, illustrate that described pole is stuck in teeth groove, continue rotary handle like this, described Hexagonal jacket just can followed by rotation.
Further, refute the portion of connecing described in and be provided with the hinged alternative pin joint of the other end of two described connecting rods of confession.
Two alternative pin joints are set, are on the one hand in order to after preventing place's pin joint from damaging, change nowhere; Another is convenient can reach position adjustments to corner block by the replacing of pin joint, realize two between pole and gear in advance or delay stuck.

Fig. 2 is the plan structure schematic diagram of the circular spanner of the embodiment of the present invention.
Fig. 3 is the enlarged diagram of part A in Fig. 2.The direction of arrow in Fig. 3 represents the direction of motion of associated components.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: gear 2, Hexagonal jacket 3, hollow sleeve 5, pad 6, circumferential band 7, connecting rod 8, back-moving spring 9a, pole 9b, refute the portion of connecing 9.
Embodiment is substantially as shown in Figure 1: the circular spanner of the present embodiment, comprise handle and hollow sleeve, a Hexagonal jacket is provided with in described hollow sleeve, described Hexagonal jacket is installed with a gear, described gear overlaps with the axis of Hexagonal jacket, is provided with and refutes the portion of connecing between described handle and hollow sleeve.
Shoulder is provided with in described hollow sleeve, described Hexagonal jacket passes the middle part of shoulder, also be provided with pad and circumferential band in described hollow sleeve, described circumferential band is fastened between described pad and hollow sleeve inwall, and described gear is folded between described pad and shoulder.
As shown in Figure 1, 2, being equipped with cavity in the middle part of described gear, Hexagonal jacket, hollow sleeve, pad, circumferential band facilitates stud to penetrate.
As shown in Figure 2, described in refute in the portion of connecing and be hinged with two poles of getting involved in respectively in hollow sleeve middle gear teeth groove, described in refute in the portion of connecing and be also provided with two by back-moving spring close in opposite directions for two poles.As shown in Figure 3, be provided with the corner block for limiting angle between two poles between two poles, described corner block is hinged on refutes in the portion of connecing.
The described portion of connecing of refuting is provided with a rotating shaft, and one end of described corner block is fixed in described rotating shaft, described in refute the portion upper surface of connecing a connecting rod be installed, one end and the rotating shaft of described connecting rod are hinged, and the other end of connecting rod is hinged on refutes the portion of connecing.The described portion of connecing of refuting is provided with the hinged alternative pin joint of the other end of two described connecting rods of confession.
As shown in Figure 3, at the beginning, described pole and gear be to relatively rotate, under the effect of described back-moving spring and corner block, described two poles can be stuck in specific teeth groove, and the angle of two poles keeps certain.Now be positioned at and refute the connecting rod connecing portion's upper surface and also can stop operating (as shown in Figure 2, the rotational angle of described connecting rod is also limited, also serves certain position-limiting action to pole).Be rotated further handle and just can rotate Hexagonal jacket, thus rotating bolt or nut.
