Description

Technical Field

[0001] The utility model relates to the technical field of rivet nuts, in particular to the technical field of rivet nuts for automobile air-conditioning brackets. Background Art

[0002] Automobile air conditioning bracket rivet nut is an important fastener in automobile air conditioning system. It is mainly used to fix the air conditioning bracket to ensure the stability and safety of the air conditioning system.

[0003] When a car is driving, it often vibrates, which causes the bolts on the air conditioner bracket to loosen easily. There is a certain installation gap between the rivet nut and the mounting hole, resulting in the rivet nut and the bracket being not connected tightly enough. The loose bolts can easily cause the nut to rotate on the bracket. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide a rivet nut for an automobile air-conditioning bracket, which can solve the above problems.

[0005] To achieve the above-mentioned purpose, the utility model proposes a rivet nut for an automobile air-conditioning bracket, comprising a fixing ring and a rod portion, a step being provided between the rod portion and the fixing ring, the step being protruding from the rod portion, a through hole being passed through the rod portion, a threaded hole being provided on the side of the through hole away from the fixing ring, a plurality of clamping ribs being provided on the upper ring of the step, the lower surface of the fixing ring being connected to the side surface of the step via the clamping ribs, and a convex edge being provided on the outer side of the clamping rib away from the step.

[0006] Preferably, the rod is a hexagonal column, and the step is also a hexagonal column.

[0007] Preferably, an annular groove is provided at the bottom end of the rod away from the fixing ring, a locking sleeve is threadedly installed in the annular groove, a locking pressure ring is provided at one end of the locking sleeve away from the annular groove, and a plurality of locking springs are provided on the inner side of the annular groove.

[0008] Preferably, the locking spring is bent toward the threaded hole.

[0009] The beneficial effects of the utility model are as follows: the utility model provides a step and a rib at the connection between the fixing ring and the rod portion. When the rivet nut is installed, the step and the rib can be better embedded in the mounting hole, so that the nut fits tightly with the mounting hole to prevent loosening; after the bolt is installed, the locking spring is tightened by the locking pressure ring, so that the locking spring radially locks the bolt, and the locking effect is good.

[0010] The features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1This is a structural diagram of Example 1 of the present utility model;

[0012] Figure 2 This is a structural diagram of Example 2 of the present utility model;

[0013] Figure 3 It is a bottom schematic diagram of embodiment 2 of the present utility model.

[0014] In the figure: 1. fixing ring; 2. rod; 3. step; 4. through hole; 5. threaded hole; 6. clamping rib; 7. annular groove; 8. locking sleeve; 9. locking pressure ring; 10. locking spring. DETAILED DESCRIPTION

[0015] Example 1

[0016] See Figure 1 The rivet nut for the air-conditioning bracket of the automobile includes a fixing ring 1 and a rod 2. A step 3 is provided between the rod 2 and the fixing ring 1. The step 3 protrudes from the rod 2. A through hole 4 is passed through the rod 2. A threaded hole 5 is provided on the side of the through hole 4 away from the fixing ring 1. A plurality of ribs 6 are provided on the step 3. The lower surface of the fixing ring 1 is connected to the side of the step 3 through the rib 6. The rib 6 is provided with a convex edge on the outer side away from the step 3. The rod 2 is a hexagonal column, and the step 3 is also a hexagonal column.

[0017] Example 2

[0018] See Figure 2 、 Figure 3 , a rivet nut for an air-conditioning bracket for an automobile, the bottom end of the rod 2 away from the fixing ring 1 is provided with an annular groove 7, a locking sleeve 8 is threadedly installed in the annular groove 7, and a locking pressure ring 9 is provided at one end of the locking sleeve 8 away from the annular groove 7, and a plurality of locking springs 10 are provided on the inner side of the annular groove 7, and the locking springs 10 are bent toward the direction of the threaded hole 5. The rest is the same as in Example 1.

[0019] Now install the bolt onto the rivet nut, then rotate the locking ring to install the locking sleeve into the annular groove. The locking ring squeezes the locking spring to lock the bolt. When removing the bolt, just unscrew the locking sleeve.

[0020] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the scope of protection of the present invention.
