The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Cannula embodiment:

referring to fig. 4 to 8, a preferred construction of the sleeve in this embodiment is shown. As shown in the figure, the sleeve is installed on part of the beam of the vehicle body framework, the beam can be a hollow section bar, and the sleeve penetrates through the section bar and is connected with the section bar, so that the sleeve is stably connected with the section bar, and the sleeve is further ensured to be stably connected with the beam of the vehicle body framework. The sleeve is used for installing a steel wire thread insert, and the steel wire thread insert is connected with a bolt to fix various devices and equipment on the automobile.

Referring to fig. 4 to 8, as shown, the sleeve includes: a body 1 and a mistake-proofing structure 2. Wherein, body 1 is solid structure, and body 1 is used for wearing to establish inside hollow section bar 3 and is connected with section bar 3. In particular, the profile 3 may be a beam of a body frame, but of course may also be another structure in a car. The inside of section bar 3 is hollow, and body 1 wears to establish two relative lateral walls of section bar 3 to body 1 and section bar 3 are in wearing to establish department welded connection, in order to ensure to be connected steadily between body 1 and the section bar 3.

The cross-sectional shape of the body 1 may be circular, oval, kidney-shaped, etc., and this embodiment does not limit this. In the present embodiment, the cross-sectional shape of the body 1 is a kidney shape.

At least one threaded bottom hole 13 is opened at first side 11 of body 1, and every threaded bottom hole 13 all extends to second side 12 relative with first side 11 of body 1. Every screw bottom hole 13 all has preset length, and every screw bottom hole 13 all is used for tapping in order to install the steel wire swivel nut, and wherein, the steel wire swivel nut is used for being connected so that device and equipment on body 1 and the car are connected with the bolt. Specifically, the first side 11 and the second side 12 of the body 1 are oppositely arranged in the length direction of the body 1, each threaded bottom hole 13 extends in the length direction of the body 1, and the preset length of each threaded bottom hole 13 can be determined according to the installation length requirement of the wire thread insert and the space after the bolt is installed, so as to avoid the bolt from touching the bottom of the threaded bottom hole 13 without being screwed with the wire thread insert.

During specific implementation, the aperture of each threaded bottom hole 13 can be determined according to the correspondingly installed steel wire thread insert and bolt, and the minimum wall thickness of the body 1 needs to be ensured, which is not limited in this embodiment. The threaded bottom holes 13 are evenly distributed in the body 1. In the present embodiment, there are two threaded bottom holes 13, and the two threaded bottom holes 13 are symmetrically disposed with respect to the vertical central axis of the first side 11 of the body 1.

When the body 1 is inserted into the profile 3 and connected to the profile 3, the body 1 will face the first side 11 of the body 1 to different directions of the profile 3 according to actual installation requirements, for example, as shown in fig. 8, the first side 11 of the body 1 of one sleeve (the sleeve on the left side in fig. 8) faces the upper side wall (the upper side wall shown in fig. 8) of the profile 3, and the first side 11 of the body 1 of the adjacent sleeve (the sleeve on the right side in fig. 8) faces the lower side wall (the lower side wall shown in fig. 8) of the profile 3. In order to avoid errors in the direction of the first side 11 of the body 1 towards the profile 3 when the body 1 and the profile 3 are installed, the error-proofing structure 2 is arranged outside the body 1, the error-proofing structure 2 is used for ensuring accurate installation of the body 1 and the profile 3, and installation errors of the body 1 and the profile 3 are prevented, namely errors in the direction of the body 1 when the body 1 and the profile 3 are installed are avoided.

It can be seen that, in this embodiment, at least one screw bottom hole 13 is seted up in first side 11 of body 1, make each screw bottom hole 13 can realize unilateral machine and add, need not two among the prior art machines and add, and then avoided leading to the problem that the jump appears in butt joint department because of two side machine add, the normal seting up of screw bottom hole 13 has been ensured, and then the sheathed tube normal use has been guaranteed, and is convenient for process, and, the accurate installation of body 1 and section bar 3 can be ensured in the setting of mistake proofing structure 2, body 1 orientation direction mistake appears when avoiding body 1 and section bar 3 installation, workman's work load has been greatly reduced, the problem that the double side machine of screw bottom hole of screw sleeve among the prior art adds and easily leads to the jump appears in butt joint department and the screw sleeve wears to establish section bar department and easily leads to the installation mistake for same size is solved.

Referring to fig. 4 and 5, a preferred configuration of the threaded bottom hole of the sleeve in this embodiment is shown. As shown in the figures, in the above embodiment, each of the threaded bottom holes 13 is integrally extruded with the body 1. Specifically, when the body 1 is manufactured, an extrusion die may be designed to integrally extrude the threaded bottom holes 13 and the body 1.
