[0020] The embodiments of the utility model are further described in detail below in combination with the drawings.

[0021] Figures 1 to 7 is the structure schematic view of the utility model.

[0022] The figure marks are as follows: head pipe A, upper head bowl set 1, bearing 11, anti-skid groove 11a, long groove 11b, barb 111, barb slope 112, upper bowl 12, hook groove 12a, guide slope 12b, holding structure 121, upper bowl positioning table 122, open holding ring 13, holding ring slope 13b, upper ball plug 14, upper steel ball 15, iron bowl 16, lower head bowl set 2, lower bowl 21, lower bowl positioning table 211, lower steel ball 22, lower ball plug 23, lower ball plug slope 231, retaining ring 24, lower plug 25.

[0023] As shown in Figures 1 to 7 The utility model discloses a child's car integrated head bowl, including the upper head bowl set 1 of clamping in the upper port of head pipe A and the lower head bowl set 2 of clamping in the lower port of head pipe A. Lower head bowl set 2 is composed of lower bearing bowl and lower plug 25. Upper head bowl set 1 is composed of bearing 11, upper bowl 12, open holding ring 13, upper ball plug 14, upper steel ball 15 and iron bowl 16, wherein bearing 11 and upper bowl 12 all adopt high-strength engineering plastic to make. The bearing 11 and upper bowl 12 made of engineering plastic not only have high strength, but also can realize light weight.

[0024] As shown in Figure 3 And Figure 6 The utility model bearing 11's bottom surface is equiradial and is shaped with six radial outward barb 111, and the upper port of upper bowl 12 is shaped with circular hook groove 12a. Bearing 11 and upper bowl 12 can be assembled together by the hooking of barb 111 and hook groove 12a, and the relative rotation between bearing 11 and upper bowl 12 after assembly. Open holding ring 13, upper ball plug 14, upper steel ball 15 and iron bowl 16 are in turn pressed in between bearing and upper bowl, and the cooperation of barb 111 and hook groove 12a can make bearing 11, upper bowl 12, open holding ring 13, upper ball plug 14, upper steel ball 15 and iron bowl 16 integrated assembly constitute an integrated upper head bowl. Integrated upper head bowl is an integrated whole structure, and convenient transportation and management, and it can be directly pressed into the upper port of head pipe A.

[0025] In the embodiment as Figure 7As shown, the lower bearing bowl in the lower head bowl set 2 is an integrated lower head bowl which is composed of a lower bowl 21, lower steel ball 22, lower ball plug 23 and retainer 24. The lower steel ball 22 is rotatably pressed in the bowl cavity of the lower bowl 21 through the lower ball plug 23, and the retainer 24 is clamped in the retainer clamping groove formed at the cavity opening of the bowl cavity. The retainer 24 is used to prevent the lower steel ball 22 and the lower ball plug 23 from coming out of the bowl cavity of the lower bowl 21. When the lower head bowl set 2 is installed with the head pipe A, the small diameter section of the lower bowl 21 is tightly clamped into the lower end of the head pipe A, and the lower bowl positioning platform 211 of the lower bowl 21 is positioned with the end port plane of the lower end of the head pipe A. The lower plug 25 is used to tightly hold the fork pipe (not shown in the drawings) arranged in the head pipe A and rotates synchronously with the fork pipe. The lower ball plug 23 is formed with a lower ball plug inclined surface 231 which is pressure-fitted with the outer inclined surface of the lower plug 25.

[0026] In order to facilitate the assembly of the upper bowl 12 and the washer 11, as shown in Figure 3 and Figure 6 The upper end of the upper bowl 12 is formed with a guide inclined surface 12b for guiding the clamping of the barb 111, and the barb 111 is formed with a barb inclined surface 112 for sliding cooperation with the guide inclined surface 12b.

[0027] The open clamping ring 13 is also used to tightly hold the fork pipe and rotates synchronously with the fork pipe. The bottom surface of the washer 11 is tightly pressed on the top surface of the open clamping ring 13, and the bottom surface of the washer 11 is formed with an anti-skid groove 11a for enhancing the friction between the washer 11 and the open clamping ring 13. The open clamping ring 13 is an open non-closed ring body which is formed with a clamping ring inclined surface 13b which cooperates with the inclined surface of the upper ball plug 14.

[0028] As shown in the embodiment, Figure 6 The lower part of the upper bowl 12 of the utility model is also formed with a clamping structure 121 which is a trapezoidal notch opened in the lower part of the upper bowl 12. The clamping structure 121 can increase the interference amount of the upper bowl 12 pressed into the head pipe A, so that the assembled upper bowl 12 can form an integral body with the head pipe A. After the upper bowl 12 is pressed in, the upper bowl positioning platform 122 of the upper bowl 12 cooperates with the upper end port plane positioning of the head pipe A.

[0029] As can be seen from Figure 2 and Figure 3 , a plurality of axially extending long groove 11b are formed in the inner hole of the washer 11 at equal intervals. The long groove 11b is a kind of hollow structure which can reduce the weight of the product without affecting the mechanical strength of the washer 11.

[0030] The utility model discloses when assembling with the head pipe A, the upper head bowl group 1 is directly pressed and mounted in the upper end in the head pipe A, the lower head bowl group 2 is pressed and mounted in the lower end in the head pipe A, and the fork passes through the lower head bowl group 2, the head pipe A and the upper head bowl group 1 in proper order.

[0031] The best embodiment of the utility model has been illustrated, and various changes or modifications made by the ordinary skill in the art will not deviate from the scope of the utility model.
