Abstract
The utility model relates to a fishing spearhead structure for a fishing device. The fishing spearhead structure includes a head adopting a cone-shaped structure, of the fishing spearhead, wherein a frustum structure extends from the lower part at the head of the fishing spearhead; a cylindrical structure extends from the lower part of the frustum structure; parallel connecting plates are mounted at the bottom of the cylindrical structure at an interval; mounting holes are formed in the connecting plates; an inclined plane is formed at the bottom of the head of the fishing spearhead, and inwards inclines to the head of the fishing spearhead adopting the frustum structure. The fishing spearhead structure is compact and convenient to manufacture, effectively prevents the fishing spearhead from disconnection when the fishing spearhead is clamped by the fishing device through the inclined plane arranged at the bottom of the head of the cone-shaped fishing spearhead, and is high in use reliability and working efficiency.
Description
Technical field
The utility model relates to fisher technical field, and especially a kind of fisher is with dragging for spearhead structure.
Background technology
Fisher is the novel fishing tool that the metal that sinks was salvaged or found to modern specialty, for maritime affairs salvaging, public security, special policeman, fire-fighting, and Archaeological Exploration, the departments such as industry cleaning under water, search and salvage victim, material evidence, shipwreck etc. in water.
The spearhead that drags for of fisher is to salvage the key components and parts of inner tube assembly, at fisher, descends smoothly throwing when dragging for spearhead position, plays smoothly card by dragging for spearhead neck position and stick into the recovery hook of fisher, then to complete smoothly the work of salvaging.The spearhead that drags for of the prior art, it is rational in infrastructure, but in use, salvaging to the phenomenon easily coming off in the process on ground, to salvage, has brought trouble, and impact is constructed.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of fisher rational in infrastructure with dragging for spearhead structure, thereby improves the dependability of fisher, increases work efficiency.
The technical scheme that the utility model adopts is as follows:
A kind of fisher is with dragging for spearhead structure, what comprise structure coning drags for spearhead head, be positioned at and drag for spearhead head bottom and be extended with frustum cone structure, the bottom of described frustum cone structure is extended with cylindrical structure, the bottom interval of described cylindrical structure is provided with parallel junction plate, on described junction plate, has installing hole; Described bottom of dragging for spearhead head is provided with inclined-plane, and described inclined-plane drags for spearhead head inner inclination to conical structure.
As the further improvement of technique scheme:
Angle between set inclined-plane and the horizontal plane in described bottom of dragging for spearhead head is 1 °-6 °;
Angle between set inclined-plane and the horizontal plane in described bottom of dragging for spearhead head is 5 °.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, easy to make, by conical, drag for the inclined-plane that spearhead head bottom arranges, effectively prevent from blocking the phenomenon of deviating from while dragging for spearhead at fisher, its dependability is good, and operating efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is the partial enlarged drawing of A portion in Fig. 2.
Wherein: 1, drag for spearhead head; 2, frustum cone structure; 3, cylindrical structure; 4, junction plate; 5, installing hole; 6, inclined-plane.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, the fisher of the present embodiment is with dragging for spearhead structure, what comprise structure coning drags for spearhead head 1, be positioned at and drag for spearhead head 1 bottom and be extended with frustum cone structure 2, the bottom of frustum cone structure 2 is extended with cylindrical structure 3, the bottom interval of cylindrical structure 3 is provided with parallel junction plate 4, has installing hole 5 on junction plate 4; The bottom of dragging for spearhead head 1 is provided with inclined-plane 6, and inclined-plane 6 drags for spearhead head 1 inner inclination to conical structure.
The angle a dragging between the bottom of spearhead head 1 set inclined-plane 6 and horizontal plane is 1 °-6 °.
The angle a dragging between the bottom of spearhead head 1 set inclined-plane 6 and horizontal plane is 5 °.
The design on inclined-plane 6, has effectively avoided the phenomenon that comes off in salvaging process, improves dependability, increases work efficiency.
In actual use procedure, the junction plate 4 that drags for spearhead bottom by securing member with drag for lance seat and be connected.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
