Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a scalable spade. Referring to fig. 1, a scalable spade, including spade pole 2 and spade head 1, spade head 1 can pass through the fix with screw on spade pole 2, and wherein spade pole 2 is including sleeve 21 and the loop bar 22 that is the cylinder form, and loop bar 22 cover is established inside sleeve 21, can stretch out and draw back the slip inside sleeve 21.

Referring to fig. 2 and 3, the sleeve 21 is equipped with a solid fixed ring 3 that is the cylinder form at the tip cover of keeping away from spade head 1, gu fixed ring 3 can fix on sleeve 21 through the viscose, gu the one end of spade head 1 is kept away from at fixed ring 3 has still integratively set up four elastic patches 4 that are the arc type, elastic patches 4 surround around the even distribution in the tip interval of solid fixed ring 3, loop bar 22 passes from elastic patches 4 middle part, elastic patches 4 in this embodiment can select for use the elastic iron piece. A rotating ring 5 which is cylindrical is arranged on the loop bar 22 in a penetrating mode, the rotating ring 5 can slide on the loop bar 22, the diameter of the rotating ring 5 is gradually reduced towards one side far away from the fixing ring 3, the whole cross section of the rotating ring 5 is trapezoidal, and the diameter of one end, close to the elastic sheet 4, of the rotating ring 5 is larger than the maximum diameter of the elastic sheet 4 when the elastic sheet is opened.

The outer peripheral side wall of the elastic sheet 4 along the sliding direction of the loop bar 22 is integrally provided with a thread bulge 6, and the inner side wall of the rotating ring 5 close to the loop bar 22 is also integrally provided with a thread groove 7 matched with the thread bulge 6. Loop bar 22 is at the gliding in-process of sleeve 21, adjusts to suitable position between loop bar 22 and the sleeve 21 after, need fix it, at this moment, overlaps 5 covers the outside at flexure strip 4 with swivel becket, according to the mutually supporting between screw thread arch 6 and the screw thread recess 7, along with constantly revolving revolves to swivel becket 5, flexure strip 4 moves towards the one end that 5 diameters of swivel becket diminishes gradually, and flexure strip 4 can receive gradually. After the elastic sheet 4 completely abuts against the side wall of the loop bar 22, the elastic sheet 4 is tightly attached to the loop bar 22, and in order to further improve the friction force between the elastic pad and the loop bar 22, the inner side wall of the elastic sheet 4 close to the loop bar 22 is adhered with a layer of friction pad 8, and the friction pad 8 in this embodiment can be a rubber pad. By means of the force applied to the axial side wall of the sleeve rod 22 and the friction force between the elastic sheet 4 and the sleeve rod 22, the sleeve rod 22 cannot slide continuously in the sleeve 21, the sleeve rod 22 is further fixed, when the sleeve rod is adjusted again, the rotating ring 5 is reversely screwed, and the elastic sheet 4 is loosened, so that the sleeve rod 22 can slide continuously.

The end portion of the fixing ring 3 close to the elastic sheet 4 is integrally provided with a circular limiting ring 9, the limiting ring 9 enables the rotating ring 5 to have a good limiting effect when being screwed, when the rotating ring 5 is screwed to a limiting state, the end portion of the rotating ring 5 close to the fixing ring 3 can be abutted to the limiting ring 9, and the situation that damage is caused due to excessive screwing is not easy to cause.

In order to improve the use effect of an operator during screwing, twelve semicircular friction convex strips 10 are integrally arranged on the side wall of the fixing ring 3 far away from the sleeve 21, the friction convex strips 10 are arranged at intervals, twelve screwing convex strips 11 are also integrally arranged on the axial side wall of the rotating ring 5 far away from the sleeve rod 22, the screwing convex strips 11 are also arranged at intervals, the friction convex strips 10 and the screwing convex strips 11 can increase the friction force between the friction convex strips 10 and the hand, the screwing convex strips 11 are convenient for screwing the rotating ring 5, and the friction convex strips 10 are beneficial to holding the fixing ring 3 during screwing.

Further optimization has still been done to the axial lateral wall of loop bar 22, the spade is when using, can carry out the application of force to spade pole 2, it is not hard up to make the spade difficult messenger loop bar 22 produce the slippage in sleeve 21 in the use, twelve concave ring 12 has been seted up at the interval on the axial lateral wall of loop bar 22, and corresponding an organic whole has set up the fixture block 13 that is the cuboid form on flexure strip 4, when fixing, along with flexure strip 4's shrink, flexure strip 4 is close to loop bar 22's lateral wall gradually, fixture block 13 can tightly block inside concave ring 12, make fixed more stable, be difficult for making the slippage between loop bar 22 and the sleeve 21 when spade work.

The sleeve rod 22 is provided with a rectangular slide way 14 along the sliding direction, a rectangular limit slider 15 is welded in the sleeve 21, the limit slider 15 is positioned in the slide way 14, and in the process of adjusting the length of the shovel, the sleeve rod 22 slides, and the limit slider 15 slides in the slide way 14 at the same time, so that the slide rod is not easy to deflect during adjustment. Meanwhile, the slide way 14 in this embodiment is closed at the end close to the shovel head 1, and when the slide bar extends to the limit position, the limit slider 15 abuts against a side wall of the slide way 14 close to the shovel head 1, so as to limit the position of the loop bar 22, and the loop bar 22 is not easy to separate from the sleeve 21 when being pulled.

Still weld two step pedal 16 in one side that spade head 1 is close to spade pole 2, step pedal 16 is the cuboid form, and the one end of keeping away from sleeve 21 at step pedal 16 sets up to the semicircle type, and the symmetry welds in sleeve 21's both sides respectively, at the in-process of using, if need use the spade to dig gets earth etc. operating personnel can step on step pedal 16 with the foot to be convenient for carry out the application of force to spade head 1, improve the holistic result of use of spade. The pedal 16 may also be provided with friction lines to reduce slippage during pedaling.

The loop bar 22 has the handle 17 that the cross-section is triangle-shaped in the one end welding of keeping away from spade head 1, and the spade can be held in being convenient for to handle 17, can also glue glutinous one deck sponge as the protection pad at the position of holding of handle 17, improves operating personnel's comfort level under the state of holding, reduces the wearing and tearing to the hand.

The implementation principle of a scalable spade of this application embodiment does: when adjusting spade length, pull loop bar 22 on the spade pole 2, make loop bar 22 slide in sleeve 21, the spacing slider 15 in the sleeve 21 plays good spacing effect to loop bar 22, difficult messenger's loop bar 22 takes place the skew when sliding, slide to the suitable position after with twisting the swivel becket 5 soon, flexure strip 4 begins to receive gradually, after the complete butt of the lateral wall of flexure strip 4 and loop bar 22, fixture block 13 on the flexure strip 4 can block in the middle of concave ring 12, and then realize that the chucking is fixed. The frictional force between friction pad 8 on the elastic strip can increase and loop bar 22 makes fixed more firm, and the pedal 16 that sets up on the spade head 1 can alleviate operating personnel's arm application of force, and the convenience of spade in the use has been improved to the handle 17 on the loop bar 22.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
