Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1-Figure 4 , this utility model provides 3 technical solutions:

[0029] Embodiment 1:

[0030] A crimping structure of a brake hard tube and a flexible tube body of an automobile brake hard tube assembly comprises a crimping head 1, a flexible tube body 2 passing through the crimping head 1, an outer wall of the flexible tube body 2 and an inner wall of the crimping head 1 forming a brake hard tube crimping area 301a, the crimping head 1 is located outside the inner wall of the flexible tube body 2 and a crimping opening 301b is arranged in a circle array, the crimping opening 301b is installed with a crimping structure for connecting the brake hard tube and the flexible tube body, wherein when the brake hard tube is connected to the flexible tube body 2 and the crimping head 1, the brake hard tube is located in the crimping area 301a and is limited by the crimping structure in the crimping opening 301b.

[0031] In this embodiment, compared with the existing direct docking, the connection between the flexible tube body 2 and the brake hard tube is added with a crimping head 1 on the outside of the flexible tube body 2 for connection, and the brake hard tube is inserted into the crimping area 301a formed by the crimping head 1 and the flexible tube body 2, and the outer wall of the brake hard tube is limited by the crimping structure and the crimping head 1.

[0032] Embodiment 2:

[0033] On the basis of Example 1: the buckling structure includes an abutment column 401a, an abutment block 401b located at the bottom of the abutment column 401a, and a sleeve wheel 401c located on the abutment column 401a, and several buckling ports 301b are symmetrically arranged corresponding to two groups of abutment columns 401a, and the abutment column 401a is fixedly connected to the abutment block 401b.

[0034] The abutment column 401a and the sleeve wheel 401c are connected by a connecting key 402a, and the limiting rings 402b are symmetrically arranged at the upper and lower ends of the connecting key 402a. The top of the sleeve wheel 401c and the upper limiting ring 402b form an upward sliding area, and the bottom of the sleeve wheel 401c and the lower limiting ring 402b form a downward sliding area.

[0035] In the present embodiment, the abutment block 401b at the bottom of the abutment column 401a directly clamps the brake hard tube in the clamping area 301a, and the inner wall end face of the brake hard tube fits with the outer wall end face of the flexible tube body to form a stable clamping state, thereby preventing the brake hard tube and the flexible tube body 2 from slipping and loosening when connected.

[0036] Furthermore, since the diameters of the brake tubes are different, after the brake tubes are inserted into the buckling area 301a, the distances from the brake tubes to the side walls of the buckling area 301a are different. Therefore, the abutment column 401a is connected to the sleeve wheel 401c through the connection key 402a, and the abutment column 401a can be raised and lowered on the sleeve wheel 401c, and the lifting area is determined by the upper sliding area and the lower sliding area.

[0037] Preferably, in summary, in order to further improve the flexibility and adjustability of the buckling of the brake tube in this embodiment, the following conditions are provided between the sleeve wheels 401c;

[0038] Embodiment three:

[0039] On the basis of the first and second embodiments: the same limiting chain 402c is sleeved on the sleeve openings of two adjacent sleeve wheels 401c, and the length of the limiting chain 402c can be adjusted by the lock before sleeve installation and the lock is locked after sleeve installation.

[0040] The limiting chain 402c controls the positions of the sleeve wheel 401c and the abutting column 401a at the buckling opening 301b, so as to adapt to brake hard pipes of different models and lengths.

[0041] The abutting column 401a is provided with a positioning hole 403a, and a positioning rod 403b inserted into the crimping head 1 passes through the positioning hole 403a. The other end of the positioning rod 403b is provided with a gasket 403c installed on the crimping head 1 with a limited position.

[0042] This embodiment also has at most one of the following two settings: after the positioning rod 403b passes through the abutment column 401a and the gasket 403c is installed to limit the position, the limiting chain 402c is stuck at this time; or the limiting chain 402c is not stuck, and the abutment column 401a slides to a suitable buckling position at the positioning port 403a.

[0043] In summary, the limiting chain 402c controls the limiting of the horizontal movement of the abutting column 401a at the buckling opening 301b, and the positioning rod 403b controls the limiting of the height movement of the abutting column 401a at the buckling opening 301b.

[0044] An internal thread 5 is formed inside the flexible pipe body 2, and a friction pattern is attached to the bottom of the abutment block 401b.

[0045] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0046] When in use, insert the brake hard tube into the buckling area 301a formed by the buckling head 1 and the flexible tube body 2, adjust the abutment column 401a and the abutment block 401b according to the distance formed by the brake hard tube and the side wall of the buckling area 301a, when the abutment column 401a and the abutment block 401b reach a stable buckling height, at this time, choose to increase or decrease the chain length of the limiting chain 402c according to the buckling position, and finally lock the limiting chain 402c. At this time, the positioning rod 403b passes through the abutment column 401a and is inserted into the buckling head 1, and the gasket 403c is installed on the buckling head 1. Shake the brake hard tube and the buckling head 1 to judge the buckling stability, and further adjust the buckling strength according to the judgment result.
