Description
Technical field
The present invention relates to a kind of anti-loosening engineer's shovels.
Background technology
Engineer shovels also known as engineer spade.One wartime German army once largely equipped and used.Liberation army is most used early in military affairs in history
Way using spades is all fought as a guerrilla before in three big campaigns on a large scale, and tunnel warfare is not liberation army nor big at last
Range.After liberation again due to historical reasons, republic once went all out with throughout the country to prepare against war and natural disasters, deep-cuts hole and the military plan such as extensively store up grain
Slightly, carried out the construction engineering of a large amount of bunker fortification, be exactly from that time engineer spade be just formally included in my army's military hardware
Scope, never unified, real military engineer's shovel, uses always very common stail spades before.
The birth of engineer's shovel can be described as the needs of existence, and soldiers have found that common spades wooden handle is too long, not portable,
It is easy to give away one's position again, then saw wooden handle short.Later this method is gradually spread out, and rear-service department at that time is again according to many old
The suggestion of soldier and site observation have much used spades for many years, some small changes are increased on present spades, be first
The top of wooden handle far from spades aperture for having opened a perforation parallel with shovel face, is secondly commonly used the mill shoveled always according to some
Situation is damaged, wooden handle is changed to thick-thin-thick streamline shape, has still added aperture respectively in shovel face both sides.Four apertures are to make
With rope spades is tied down to wrap in march, swim with one's weapons, strenuous exercise and for a long time be not easy to fall on the march, streamlined wooden handle
It is more suitable for holding, also uses traditional military green paint.Engineer's shovel is that the conventional of engineer is equipped with equipment, is used originally for Military Functions, but
Later engineer's shovel is also commonly used for mountain-climbing usually, camps etc. among the work such as activity or gardening, the disaster relief.
Currently, popularizing with outdoor activities, the purposes of engineer's shovel is also more and more extensive.Outdoor fan carries engineer
Shovel, and it is desirable that engineer shovel can play important function, can solve the problems, such as to encounter outdoors various.And existing engineer's shovel
Structure design not reasonableization, the outer end of coupling bar is set as two groups of screw threads of thickness, and fine thread is for connecting spade, coarse-pitch thread
Shovel head is fixed for attaching nut, while nut is designed as half internal thread, and there is shake nut when using to loosen and nut
The problem of junction insufficient strength.
Invention content
The technical problem to be solved in the present invention is to provide a kind of anti-loosening engineer's shovels.
The technical scheme is that：A kind of anti-loosening engineer's shovel, it is characterised in that anti-loosening engineer shovels by shoveling
Head, connection sheet, coupling bar, gasket, nut, spade and bolt composition, the top of shovel head are connected to connection sheet, and connection sheet is groove
The steel plate of type is connected to coupling bar at the center of connection sheet by bolt work, the outer end of coupling bar be equipped with on spade in
The corresponding screw thread of nut, coupling bar are lived with spade by the screw thread on outer end and are connected；Spade top end is equipped with and nut inner nut
Corresponding external screw thread；Nut is fixed shovel head by gasket and connection sheet.
A kind of anti-loosening engineer's shovel of the present invention, it is characterised in that the nut is by being equipped with spring pad between gasket
Circle.
A kind of anti-loosening engineer's shovel of the present invention, it is characterised in that 6 internal thread of nut is whole formula.
A kind of anti-loosening engineer's shovel of the present invention, it is characterised in that the spade tail end is equipped with the handle of connection lengthening handle living
Nut, lengthening handle are equipped with handle screw thread corresponding with handle nut.
A kind of anti-loosening engineer's shovel of the present invention, it is characterised in that the connection sheet in the shovel head be equipped with gasket and
The positioning stuck point of nut cooperation, it is respectively 2 °, 88 °, 180 ° that can make the angle between shovel head and spade.
A kind of anti-loosening engineer's shovel of the present invention is in use, the coupling bar in shovel head is connected on spade, then by shovel head
It is adjusted to suitable position, using nut by connection sheet clamping, lengthening handle can be added to adjust the length of spade.
The advantage of the invention is that：Coupling bar outer end is all connected in spade by screw thread, and nut is whole formula screw thread
This structure makes the intensity of spade junction greatly improve, and nut whole process formula screw thread and spring washer overcome the easy pine of the prior art
Dynamic problem, nut whole process formula screw thread have good switching performance, and using effect is more obvious,
Structure of the invention design is simple, and use is easy to operate, can realize quick positioning.
