Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Example 1:

referring to fig. 1-2, the reinforced backpack comprises a backpack top beam 1, a backpack vertical beam 2 and a backpack bottom beam 3, which are all rectangular, and with reference to the state of the reinforced backpack mounted on the embroidery machine frame, the backpack top beam 1 and the backpack bottom beam 3 are horizontally and horizontally arranged, the backpack vertical beam 2 is vertically arranged, and the ends of the backpack top beam 1, the backpack vertical beam 2 and the backpack bottom beam 3 are vertically connected in sequence. The reinforced backpack has the main functions of assisting in reinforcing the structural strength of the embroidery machine frame, improving the load-carrying capacity of the embroidery machine frame, enhancing the rigidity and avoiding bending deformation, and for the reinforced backpack, the length of the backpack top beam 1 is greater than that of the backpack bottom beam 3, so that the stress load of the backpack top beam 1 is greater correspondingly, the whole formed by the backpack top beam 1 and the backpack vertical beam 2 is a main stress structure of the reinforced backpack, and the structural strength of the reinforced backpack top beam 1 and the backpack vertical beam 2 can be enhanced greatly.

Therefore, the backpack top beam 1 and the backpack vertical beam 2 are of an integral structure, and both are hollow, that is, the top plate 11 of the backpack top beam 1 and the outer plate 22 of the backpack vertical beam 2 are integrated and vertically bent, the bottom plate 12 of the backpack top beam 1 and the inner plate 21 of the backpack vertical beam 2 are integrated and vertically bent, a plurality of first reinforcing members 41 are fixedly connected between the top plate 11 and the bottom plate 12 of the backpack top beam 1, and a plurality of second reinforcing members 42 are fixedly connected between the inner plate 21 and the outer plate 22 of the backpack vertical beam 2, the first reinforcing members 41 can improve the vertical stress load of the backpack top beam 1, and the second reinforcing members 42 can improve the horizontal stress load of the backpack vertical beam 2.

Arbitrary two adjacent first reinforcement 41 slants are crisscross, and arbitrary two adjacent second reinforcement 42 slants are crisscross, first reinforcement 41 and second reinforcement 42 not only can make the roof 11 and the bottom plate 12 of knapsack back timber 1, the inner panel 21 and the planking 22 moment of flexure of knapsack founding roof beam 2 reduce with the crisscross arrangement structure of adjacent slant, improve the whole rigidity of knapsack back timber 1, knapsack founding roof beam 2, but also can effectively resist the structural damage that knapsack back timber 1, knapsack founding roof beam 2 and receive the normal stress and cause.

In addition, any two adjacent first reinforcements 41 do not intersect, any two adjacent second reinforcements 42 do not intersect, and if the adjacent first reinforcements 41 and the adjacent second reinforcements 42 are arranged to have an intersecting structure, although the structural strength can be further strengthened, the distribution density of the first reinforcements 41 and the second reinforcements 42 is increased, so that the overall weight of the reinforced backpack is relatively large, and the performance of the reinforced backpack is adversely affected, but the non-intersecting scheme of the adjacent first reinforcements 41 and the adjacent second reinforcements 42 provided in the embodiment already enables the backpack top beam 1 and the backpack upright beam 2 to have sufficient overall strength and structural rigidity.

A third reinforcement 43 is fixedly connected between the top plate 11 of the backpack top beam 1 and the outer plate 22 of the backpack vertical beam 2, the third reinforcement 43, the adjacent first reinforcement 41 and the adjacent second reinforcement 42 are staggered in an inclined direction and do not intersect with each other, and the third reinforcement 43 mainly serves to reinforce the structural strength of the intersection of the backpack top beam 1 and the backpack vertical beam 2, so as to prevent the two from twisting and changing the mutually perpendicular structures. Furthermore, the third reinforcing member 43 and the adjacent first reinforcing member 41 and second reinforcing member 42 form a substantially triangular overall structure having better structural strength.

In the present embodiment, the first reinforcing member 41, the second reinforcing member 42, and the third reinforcing member 43 are square tubes, which reduces material consumption and overall weight.

A first reinforcing beam 51 is fixedly connected between the backpack bottom beam 3 and the backpack vertical beam 2, a reinforcing block 53 is fixedly connected to the backpack vertical beam 2, a square groove for inserting and embedding a rectangular structure is formed by the top surface of the first reinforcing beam 51, the inner plate 21 of the backpack vertical beam 2 and the bottom surface of the reinforcing block 53, and a second reinforcing beam 52 is fixed between the backpack top beam 1 and the backpack vertical beam 2. The first reinforcing beam 51 and the second reinforcing beam 52 further improve the structural strength of the reinforced backpack.

Example 2:

referring to fig. 3, the reinforced backpack, compared to embodiment 1, is distinguished by:

the backpack standing beam is internally provided with a reinforcing plate 44, the reinforcing plate 44 is parallel to the side plates of the backpack standing beam, the reinforcing plate 44 and the second reinforcing members 42 are of an integral structure, wherein the reinforcing plate 44 and the second reinforcing members 42 are closest to the backpack top beam, and the reinforcing plate 44 and the second reinforcing members 42 form an integral mechanism with better strength and rigidity, so that the backpack standing beam has more excellent transverse stress load performance. A plurality of parallel and side-by-side reinforcing plates 44 may also be provided, depending primarily on the thickness of the backpack uprights and the load-bearing capacity requirements.
