Embodiment Construction

[0027] The present invention will be described in further detail below by means of specific embodiments:

[0028] The reference signs in the drawings of the description include: cover 1, bayonet 2, block 3, large sleeve 4, small sleeve 5, gear 6, teeth 7, arc plate 9, semicircular plate 10, Ball 11.

[0029] The telescopic sleeve includes a large sleeve 4 and a small sleeve 5 slidingly connected in the large sleeve 4. A gear 6 is provided on the side wall of the large sleeve 4, and a gear 6 is provided on the side wall of the large sleeve 4. The insertion entrance for penetration, the small sleeve 5 is provided with a row of teeth 7, the arrangement direction of each tooth 7 is consistent with the length direction of the small sleeve 5, and the large sleeve 4 is provided with a cover outside the insertion entrance. A cover 1 for placing the inlet;

[0030] Such as figure 1 , 2 As shown, the lower half of the gear 6 is arranged in the large casing 4 and meshes with the row ...

Abstract

The invention discloses mechanical pipe fittings and particularly relates to a connecting structure of an extensible casing. The side wall of a large casing is provided with a gear; the side wall of the large casing is provided with a placement opening for the gear to penetrate; a small casing is provided with a row of teeth; the arrangement direction of the teeth is the same as the length direction of the small casing; the lower half portion of the gear is arranged in the large casing and meshed with the row of teeth; rolling balls are arranged in at least two tooth grooves of the upper half portion of the gear. According to the extensible casing, the defects that the energy consumption is produced in the installation process and the installation is complex in the prior art are overcome, the extensible casing is limited through the gear with the rolling balls, and the installation is easy.

Description

technical field [0001] The invention relates to a mechanical pipe connector, in particular to a connection structure of a telescopic sleeve. Background technique [0002] The two pipe fittings are inserted together, and one sleeve can slide in the other through the control of the pipe diameter. However, a certain locking device is required at the joint of the two pipes. For example, when the bicycle seat riser is inserted into the seat sleeve, the locking method is usually to open a clamping groove at the opening end of the large sleeve, and the length of the clamping groove is It is approximately equal to the diameter of the casing. There is a small casing with a smaller diameter slidingly connected in the large casing. After the small casing is inserted into the casing, use a locking nail or a set screw to tighten the small casing in the clamping groove through the clamping groove. , so as to realize the limit of the telescopic sleeve. [0003] However, the position-limi...
