Abstract

The utility model relates to a mechanical mounting fastening tool, specifically speaking are box spanner suitable for long bolt connecting piece. In the current spanner, the longer bolt of the unable fastening of box spanner, and ordinary spanner receives the restriction of operating space. The utility model discloses a sleeve pole, collet head, handle, the handle vertical fixation is in sleeve pole upper end, sleeve pole lower extreme and collet head upper end connect detachable grafting assembly through the torque, the tip has been equipped with the polygon inside callipers hole that the card ends the effect under the collet head, the inside of sleeve pole and collet head is equipped with vertical passageway of intercommunication each other. The utility model discloses it is rational in infrastructure, establish the passageway of mutual intercommunication in the convenient to carry, sleeve pole and collet head for the fastening of long bolt connecting piece, the be convenient for advantage of operation of full play box spanner, removable collet head is suitable for multiple specification nut card to be ended, has reduced the operation degree of difficulty by a wide margin, has improved work efficiency.

Description

A kind of box spanner being applicable to long bolt connector
Technical field
The utility model relates to Automatic manual transmission fastened tools, specifically a kind of box spanner being applicable to long bolt connector.
Background technology
Box spanner is the fastened tools that Automatic manual transmission is conventional, has easy to operate feature.Existing socket wrench structure is simple, and when the bolt fastener longer for the fastening body of rod, often generation bolt end contacts phenomenon that cannot be fastening at the bottom of sleeve hole clipping.In the O&M operation of overhead transmission line, this kind of situation often occurs, and the nut configuration that many overhead line structures use is special, for adapting to work high above the ground, nut inner ring adds check washer usually, coordinates closely with screw rod, and whole fastener cycle all needs to use spanner.Therefore, when sleeve type spanner cannot use, utilize common wrench (fork spanner or adjustable wrench) to carry out disassembling operations to waste time and energy, especially the fastening point of some privileged sites, nut often rotates a circle all to be needed to switch spanner low-angle through 5 ~ 6 times and repeatedly pulls, and overhead line operation distance more than 8 meters, ground mostly, staff needs to be suspended in for a long time high-altitude, working strength and danger are comparatively large, inefficiency.In addition, another defect adopting common wrench is after nut gets loose completely, very easily by falling from high altitude, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of novel box spanner, establishes passage as the cavity volume of screw rod in spanner, for the tightening operation of long bolt and special nut fastener, convenient to use, significantly improves operating efficiency.
The purpose of this utility model is achieved through the following technical solutions:
Be applicable to a box spanner for long bolt connector, comprise socket bar, collet head, handle; The inside of socket bar and collet head is equipped with longitudinal passage; Hole clipping in the polygon that collet head bottom has been provided with locking effect, interior hole clipping is communicated with the passage lower end of collet head;
Handle is laterally vertically fixed on socket bar epimere; The dismountable grafting in socket bar lower end and collet head upper end is assembled, and socket bar and collet head are connected by polygon torque adapter and coordinate, and are located by jackscrew; The passage of plug-in mounting state lower sleeve bar and collet head is interconnected.
Further, in the polygon of described collet head end, the inwall of hole clipping is provided with magnetic material layer.
The beneficial effects of the utility model are: rational in infrastructure, volume is little, easy to carry, the passage be interconnected is established to hold long bolt in this tool sleeve bar and collet head, make the use of box spanner not by the impact of spiro rod length, give full play to the advantage of box spanner convenient operation, particularly in transmission line high-altitude operation, significantly reduce operation easier, improve operating efficiency.This instrument can according to condition of construction by changing the fastening of collet head suitable for various size nut; The adsorbable nut got loose of the magnetic material layer that in collet head, hole clipping is included, prevents the generation of falling object from high altitude.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail.
Accompanying drawing explanation
Fig. 1: structural representation of the present utility model;
The A-A sectional view of Fig. 2: the utility model Fig. 1;
The B-B sectional view of Fig. 3: the utility model Fig. 1;
Fig. 4: the structural representation of the utility model collet head.
Detailed description of the invention
In figure: 1, socket bar, 11, socket bar passage, 2, collet head, 21, collet head passage, 22, interior hole clipping, 3, handle.
Embodiment 1
As can be seen from Figure 1, the utility model comprises socket bar 1, collet head 2, handle 3; Socket bar 1 lower end and collet head 2 upper end are assembled by the dismountable grafting of torque adapter, and are located by jackscrew; Socket bar 1 and collet head 2 inside are respectively equipped with longitudinal socket bar passage 11 and collet head passage 21, and after socket bar 1 and collet head 2 plug-in mounting, socket bar passage 11 and collet head passage 21 are interconnected.
Hole clipping 22 in the polygon that collet head 2 bottom has been provided with locking effect, interior hole clipping is communicated with collet head passage 21 lower end.
Interior hole clipping 22 inwall of described collet head 2, with one deck magnetic metallic layers, in order to adsorb nut, prevents nut to get loose generation falling object from high altitude.
The external wall cross-section of the present embodiment middle sleeve head 2 epimere is that polygon is as torque adapter, socket bar passage 11 hypomere inwall is polygonal inner chamber, this polygon inner chamber coordinates transmitting torque (also torque adapter can be arranged on socket bar lower end, the polygon inner chamber be mated is located on collet head) with the torque adapter of collet head;
Handle 3 is laterally in T shape is vertically fixed on socket bar 1 epimere, and guarantees that socket bar passage 11 upper end is open.
The utility model box spanner overcomes the defect of existing box spanner and common wrench, uses this instrument clamp nut, and not by the restriction of the factor such as long bolt and narrow space, its socket bar can go deep into operating in narrow space.When running into the connector compared with long bolt, screw rod passes the passage of socket bar and collet head, and stretched out by socket bar upper end, give full play to the advantage of box spanner convenient operation, whole circle pulls nut uniformly, significantly reduces operation easier, improves operating efficiency.
Finally should be noted that: above embodiment is not intended to limit for illustration of the technical solution of the utility model; those skilled in the art modifies to embodiment or carries out equivalent replacement to portion of techniques feature; and do not depart from the essence of technical solutions of the utility model, all should be encompassed within the utility model scope required for protection.
