Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

A chain saw training frame suitable for forest fire fighting comprises a triangular support 1, a support plate 2 and a fixing device, wherein three support legs of the triangular support 1 are of a telescopic structure, and in the specific practical training, the triangular support is of the telescopic structure, so that the height is adjusted conveniently in the training process, the chain saw training frame is convenient to store and carry, and the three support legs can be contracted to the shortest length when being stored and carried, so that the space is saved;

a supporting plate 2 is horizontally welded at the top end of the triangular bracket 1, and a wood fixing device is welded at the top end of the supporting plate 2; the wood fixing device is composed of two equal-size arc plates 3 with the same structure, one ends of the two arc plates 3 are horizontally and fixedly connected with a connecting plate 4, the connecting plate 4 is connected with a nut 6 through a screw rod 5, and the other ends of the two arc plates 3 are connected through a self-locking buckle 7; in the middle of the actual training, can with break off with the fingers and thumb from the handle of hasp 7, loosen screw rod 5 and nut 6 soon of connecting plate 4 department again, the distance between two arc boards 3 is greater than the external diameter of training wood 11 about making, then place between two arc boards 3 with training wood 11, with dying from hasp 7 lock, recycle screw rod 5 and nut 6 with the one end fastening of connecting plate 4, training wood 11 will block like this and put between two arc boards 3, when carrying out the chain saw operation exercise, need not one person and press training wood one end, another just can carry out the real operation training at the other end, if the training wood is longer, can adopt a plurality ofly the utility model discloses the cooperation is used to this purpose that plays firm.

With a plurality of circular slot 8 is seted up to the top surface on the circular arc board 3 of backup pad 2 rigid coupling, and at the internally mounted ball 9 of circular slot 8, above-mentioned ball 9 can be solid steel ball, can rotate at will in circular slot 8, nevertheless can not break away from circular slot 8, this setting can be guaranteed when placing the training wood toward between two radian boards, make ball 9 and training wood 11 contact, training wood 11 slides on ball 9, make placing of training wood more smooth, and ball 9 adopts solid steel ball, can ensure not to be crushed by the training wood or blocked because training wood surface unevenness.

As preferred scheme, it is further, three landing legs of triangle-shaped support are the bushing structure to at inside sheathed tube surperficial equidistance symmetry be equipped with a plurality of screw holes, be equipped with a screw hole on outside sheathed tube surface, and at outside sheathed tube screw hole department threaded connection governing valve 10, inside sheathed tube and outside sheathed tube screw hole internal diameter is the same, and with governing valve 10 phase-match, in the middle of the actual training, can insert governing valve 10 in inside sheathed tube and outside sheathed tube screw hole according to actual needs, guarantee the stability of support.

The working principle is as follows:

when a firefighter conducts chain saw operation training, the height of the triangular support 1 can be adjusted firstly, then the self-locking buckle 7 is broken off, the screwed nut 7-1 of the self-locking buckle 7 and the screw rod 5 and the nut 6 at one end of the connecting plate 4 are unscrewed, the distance between the two arc plates is larger than the outer diameter of the training wood, then the training wood 11 is inserted between the two arc plates 3, finally the self-locking buckle 7 is locked, and then the screw rod 5 and the nut 6 are screwed, so that the training wood 11 can be fixed between the two arc plates 3, and therefore, when the firefighter conducts the chain saw operation training, the other end of the training wood is required to be pressed when one firefighter conducts the chain saw operation training like the background art, manpower is saved, and the use safety is improved; in the training process, if the training wood is longer, a plurality of the training wood can be selected for matching use, so that the stability of the training wood can be improved; along with the progress of the chain saw training, the length of the training wood can also be shortened along with the operation of the chain saw, at the moment, the training wood only needs to be pushed to be extended outwards along with the rolling of the solid steel balls in the circular grooves, and then the self-locking buckle 7, the screw rod 5 and the nut 6 are screwed and fixed, so that the firefighter can conveniently continue to carry out the operation training of the chain saw; when training wood needs to be placed from the upper surface, the screw rod 5 and the nut 6 can be loosened to separate the screw rod 5 from the nut 6, the self-locking buckle 7 is broken off, the screwed nut 7-1 from the buckle 7 is opened, the screwed nut 7-1 is separated from the buckle 7, the upper connecting plate is of an integral structure from the upper part of the buckle 7 and the upper arc plate, the arc plate on the upper part can be taken down, the training wood is placed on the lower arc plate, and then the upper arc plate is connected with the lower arc plate through the self-buckle 7, the screw rod 5 and the nut 6, so that the training wood with the larger outer diameter can be fixed between the two arc plates.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
