Detailed Description

The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.

Example (b):

a rear bottom fork with high stability is disclosed, referring to fig. 1, comprising a bottom fork main body 1, wherein the bottom fork main body 1 has a symmetrical structure, the bottom fork main body 1 comprises a beam body 11, two fork bodies 12 respectively arranged at two ends of the beam body 11, and a sleeve body 13 arranged at the front end of the two fork bodies 12. A locking groove 121 is formed at the rear end of each of the two bifurcating bodies 12. The balance adjusting component 2 is fixed in the clamping groove 121. The balance adjusting assembly 2 comprises a shaft rod 21, nuts 22 which are connected to two ends of the shaft rod 21 through threads and fastened on the clamping grooves 121, and a balancing weight 23 which is sleeved on the shaft rod 21 and slides movably. Both ends of the shaft 21 are threaded to engage nuts 22 for fastening. During assembly, the nut 22 engages the threaded structure to secure the shaft 21 to the slot 121.

The counterweight 23 is provided with a first fastening bolt 24, and the first fastening bolt 24 is used for fixing the counterweight 23 at any position of the shaft rod 21. The weight 23 is provided with a threaded hole for the first fastening bolt 24 to be mounted, the threaded hole penetrates through the weight 23, and when the first fastening bolt 24 is fitted in the threaded hole, the weight 23 is fastened on the shaft rod 21 by the first fastening bolt 24.

Therefore, on the basis of the structural symmetrical design, the balance adjusting assembly 2 is matched, the structural stability can be optimized, when the structure is unbalanced in left and right, the compensation for the unbalance of the unbalance is kept by adjusting the left and right positions of the balancing weight 23 on the shaft rod 21, and therefore the unbalance can be overcome, the balance of the left and right balancing weights is kept, and the balance is stable.

Specifically, further optimize in this scheme, in the above example, the secondary rod 3 perpendicular to the axle rod 21 is further designed at the middle position where the axle rod 21 is further provided, the other end of the secondary rod 3 is fixed on the cross beam body 11, the weight block 4 is sleeved on the secondary rod 3, the second fastening bolt 5 is provided on the weight block 4, and the second fastening bolt 5 is used for fixing the weight block 4 at any position of the secondary rod 3. In the same way, the weight block 4 has the same function as the counterweight block 23, and the difference lies in that the balance of the adjusted counterweight is different, mainly used for adjusting the front and rear weights, and can effectively adjust the front and rear weights, so that the structure is more stable.

In this scheme, can also be provided with breach 231 on the balancing weight 23, balancing weight 23 passes through breach 231 card and goes into axostylus axostyle 21. Thus, the counterweight 23 can be slid or transited to the left and right sides conveniently, and the assembly is easy.

Referring to fig. 1 and 2, it can be seen that the slot 121 is linear, and the shaft 21 is fixed at any position along the length of the slot 121. The clamping groove 121 is linear, and the front and rear structures can be adjusted to be stable by adjusting the fixed position of the shaft rod 21 on the clamping groove 121.

In the above solution, the secondary rod 3 may be a single component as the shaft 21, or may be designed as a structure, in a further optimized solution, the secondary rod 3 includes a female rod 31 and a secondary rod 32, and the female rod 31 and the secondary rod 32 are sleeved and telescopically slid. As can be seen from the combination of fig. 1 and 3, the auxiliary rod 3 is fixed with the cross beam in a rotating way, the main rod 31 and the auxiliary rod 32 are oval in cross section, and the main rod 31 and the auxiliary rod 32 are mutually fastened in a rotating way. Be provided with the mounting hole on the crossbeam and supply vice pole 3 to pass to a tip of vice pole 3 can be spacing but can rotate on the mounting hole in this mounting hole, and because female pole 31 and son pole 32's independent cooperation structure, some angles of relative rotation can take place, thereby realize interference fit, make female pole 31 and son pole 32 fixed, when female pole 31 and son pole 32 cross section were parallel to each other, then can realize stretching out and drawing back.

The telescopic function of the auxiliary rod 3 is realized through the sleeved structure of the female rod 31 and the sub-rod 32 of the auxiliary rod 3, and the position of the shaft rod 21 on the clamping groove 121 can be adjusted. The operation of fastening the sub-rod 32 and the telescopic adjustment is performed by rotating the main rod 31, and the use is simple and convenient.

The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
