Description
Technical field
The utility model is related to the technical field of stop sleeve, more particularly to thin-wall section stop sleeve
Technical field.
Background technology
With the development trend of automotive light weight technology, the thin-wall section in closed cross-section or non-close section is in manufactures such as automobiles
The application of industry is on the increase, it is mainly used for that auto parts and components are fixedly mounted, and fixed installation mode common at present mainly has
Two kinds：First, opening up through-hole on thin-wall section, when installing parts, bolt, which is passed through, needs parts and thin-walled to be mounted
The through-hole of section bar, and tightened using nut, it would be desirable to the parts of installation are fixed on thin-wall section.However it uses this
Although mode bonding strength is higher, easily thin-wall section is caused to squeeze, thin-wall section is caused to deform, in order to ensure thin wall type
The structural strength of material, it will usually reinforcing rib in thin-wall section is set, however so increases the dosage of raw material, so as to
Considerably increase manufacture cost.Second is that the welded nut on thin-wall section, it would be desirable to which the parts being fixed on thin-wall section lead to
Bolt fixation is crossed to be located on nut.However bonding strength is poor in this way, after long-term use, nut is easily from thin
It comes off on wall-shaped material.
Utility model content
The purpose of this utility model is exactly to provide a kind of simple in structure to solve above-mentioned deficiency, and locking securely, can
It effectively prevent loosening, and good inner support effect can be played to thin-wall section, the section bar for effectively reducing manufacture cost uses paperback
Formula inner support sleeve.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows：
Section bar flush mounting type inner support sleeve, it is made of cylinder and pressure head, and the cylinder is integrally cylindrical, in cylinder
Bottom be provided with the positive stop lug boss extended downwardly, annular locking slot is offered on the lateral wall of the positive stop lug boss, in the cylinder
Centre bore is offered in vivo, and the top setting of the cylinder positive stop lug boss is in embedded division, the central hole on the cylinder top
Offer annular groove, offered in the pressure head with the corresponding centre bore in body centre hole, opened on the lateral wall of pressure head
Equipped with interlocking annular groove, the pressure head interlocks annular groove holding in the annular groove on cylinder top by it.
Internal thread is provided on the madial wall in the body centre hole.
Annular knurl is provided on the lateral wall of the embedded division.
The lower part setting that annular groove is interlocked on the pressure head is tapered.
The centre bore is through-hole.
The top setting that annular groove is interlocked on the pressure head is tapered.
The utility model is using the attainable advantageous effect of above-mentioned technical solution institute：By pressure head to cylinder annular
The side wall of groove carry out squeeze it is swollen, make to be resisted against at the top of cylinder on the bottom surface of the thin-wall section at first through hole, so as to play
Good position-limiting action, effectively prevents the phenomenon that cylinder is deviate from from thin-wall section；Thin-walled is embedded in by the embedded division of cylinder
In section bar, while thin-wall section is deformed upon and is embedded into annular locking slot, and by this section brace sleeve, securely lock is put in thin-walled
On section bar, so as to play good locking effect, this section brace sleeve can be effectively prevent to get loose, in the outer of embedded division
Annular knurl is provided on side wall, so as to play good anti-rotation effect, further improves locking intensity.The both ends of cylinder
It bears against on the inner surface of thin-wall section, so as to play the role of good inner support to thin-wall section, effectively increases
The structural strength and ability of anti-deformation of thin-wall section, and need not reinforcing rib be set in thin-wall section, significantly reduce manufacture
Cost.

Specific embodiment
As shown in Figure 1, section bar flush mounting type inner support sleeve, it is made of cylinder 1 and pressure head 2, as shown in Fig. 2 and Fig. 3,
The cylinder 1 is whole cylindrical, and the positive stop lug boss 3 extended downwardly is provided in the bottom of cylinder 1, is opened up in the cylinder 1
There is centre bore 4, which can be that through-hole may be blind hole.It is provided on the madial wall of 1 centre bore 4 of cylinder
Internal thread 5, offers annular locking slot 6 on the lateral wall of the positive stop lug boss 3, and the top of 1 positive stop lug boss 3 of cylinder is set
It puts in embedded division 7, annular knurl 8 is provided on the lateral wall of the embedded division 7, to play the role of anti-rotation, on 1 top of cylinder
Centre bore 4 at offer annular groove 9.As shown in Fig. 4 and Fig. 5, offered in the pressure head 2 and 1 centre bore of cylinder, 4 phase
Corresponding centre bore 10 offers interlocking annular groove 11 on the lateral wall of pressure head 2, the lower part of annular groove 11 is interlocked on the pressure head 2
Set it is tapered, on the pressure head 2 interlock annular groove 11 top may also set up it is tapered, the pressure head 2 pass through its interlock annular groove
11 holdings are in the annular groove 9 on 1 top of cylinder.
As shown in Figure 6, this section brace sleeve when mounted, first opens up 13 He of first through hole respectively on thin-wall section 12
Then cylinder 1 is caught in from first through hole 13 in thin-wall section 12 by the second through-hole 14, and make 3 holding of positive stop lug boss logical second
