That is to say, the material of traveller spring holder 1 adds the glass fiber material of a certain proportion for the PP material, replaces traditional rubber materials like this, and the performance is better, and the reliability is better, is fit for the use of cross-country vehicle at long-time complicated operating mode.

The structure of the spool spring seat 1 according to the embodiment of the present invention includes a spring seat body 11 and a protector connecting portion (second mounting portion 12), and the present invention will be further described with reference to the accompanying drawings.

The slide column protecting sleeve 2 and the slide column spring seat 1 can be fixedly connected or detachably connected. Embodiments of the present invention are illustrated only with a detachable connection. Alternatively, as shown in fig. 2, the spool protector 2 is snapped onto the spool spring seat 1 via the second mounting portion 12.

As shown in fig. 2, the port of the lower end of the spool spring seat 1 is provided with a clamping structure, and the clamping structure is matched with a convex rib 21 on the spool protecting sleeve 2. Wherein, the number of the clamping structure is matched with the number of the convex ribs 21.

Alternatively, as shown in fig. 3 and 4, the spring seat body 11 has a cylindrical support surface structure 13 at the upper end and a second mounting portion 12 at the lower end. A cylindrical tubular structure is arranged on the second mounting portion 12, a step 121 is arranged at the port of the cylindrical tubular structure, and a plurality of clamping structures are arranged on the circumference of the step 121.

The plurality of snap features may all be distributed around the circumference of the step 121. Wherein, a plurality of joint structures include first joint structure 122 and second joint structure 123, and the protruding height of first joint structure 122 is greater than the protruding height of second joint structure 123, sets up protruding lower second joint structure 123 of height like this and can be convenient for the installation of traveller lag 2, sets up the higher reliability of being connected between traveller lag 2 and the traveller spring holder 1 of protruding high first joint structure 122 of height. Taking 3 clamping structures as an example, a step is arranged at the lower port part of the cylindrical structure, three clamping structures are uniformly distributed on the circumference of the step, wherein two clamping structures are wide protrusions (first clamping structures 122) on which concave clamping grooves are arranged, the positions of the concave clamping grooves are close to the upper edges of the wide protrusions, the width of the concave clamping grooves is the same as the width of the convex ribs 21 on the sliding column protecting sleeve 2, and the circumferential length of the concave clamping grooves is the same as the length of the convex ribs 21 on the sliding column protecting sleeve 2; one of the clamping structures is a narrow protrusion (a second clamping structure 123), the position of the narrow protrusion is close to the lower port of the cylindrical structure, and the narrow protrusion is used for facilitating the installation of the sliding column protecting sleeve 2, so that one of the protruding ribs 21 on the sliding column protecting sleeve 2 is clamped between the narrow protrusion and the upper step of the narrow protrusion. Like this, the setting of this structure can effectively promote the easy and convenient nature of combination between traveller spring holder 1 and the traveller lag 2, can effectively guarantee the firm nature after the combination again between traveller spring holder 1 and the traveller lag 2 simultaneously. Correspondingly, as shown in fig. 5, one end of the slide column protecting sleeve 2 is of a straight cylinder structure, and a convex rib 21 which protrudes inwards is arranged on the straight cylinder structure. Wherein, the number of protruding muscle 21 is the same with the number of joint structure, and the shape and size of protruding muscle 21 also looks adaptation with the shape and size of joint structure to the number of joint structure and protruding muscle 21 is 3 as an example, and the upper end of traveller lag 2 is for having the straight section of thick bamboo structure of open-ended, and the internal diameter of straight section of thick bamboo structure and the external diameter phase-match of traveller spring seat 1 lower step 121 part, and the length of straight section of thick bamboo structure just in time equals traveller lag 2 and traveller spring seat 1 matched with length. Three inwards-sunken convex ribs 21 are uniformly distributed on the inner side of the straight cylinder structure in the circumferential direction, and the three convex ribs 21 are used for being clamped with the clamping structure of the sliding column spring seat 1, so that the sliding column spring seat 1 and the sliding column protecting sleeve 2 are combined with each other and then fixed. During installation, the straight-tube structure at the upper end of the sliding column protecting sleeve 2 is inserted into the lower port of the sliding column spring seat 1, and then the sliding column protecting sleeve 2 is rotated, so that the convex ribs 21 of the sliding column protecting sleeve 2 are respectively matched with the clamping structure of the sliding column spring seat 1, and finally the combination of the sliding column spring seat 1 and the sliding column protecting sleeve 2 is realized.
