Detailed Description
The following are specific embodiments of the utility model and the technical solutions of the utility model will be further described with reference to the accompanying drawings, but the utility model is not limited to these embodiments.
Example 1
As shown in fig. 1 to 3, the plug rivet comprises a plug main body section 1, a chamfer 11 is arranged at the front end of the plug main body section 1, a conical section 2 and a cylindrical section 3 connected to the rear end of the conical section 2 are arranged at the rear end of the plug main body section 1, the diameter of the cylindrical section 3 is larger than that of the plug main body section 1, a plurality of riveting teeth 4 which are circumferentially distributed and axially arranged along the cylindrical section 3 are arranged on the cylindrical section 3, the riveting teeth 4 are prolonged on the conical section 2, and the width of the riveting teeth 4 arranged on the conical section 2 is gradually reduced from front to back. The bolt rivet is formed through cold heading, and the back end of a formed blank is processed through hobbing to obtain a riveting tooth 4.
The inner hole wall of the fixed object (wood) is clenched through the riveting teeth 4, so that the stability of connection is ensured, and the fixed object (wood) is prevented from circumferential loosening, deviation and the like.
To achieve fixation of the fixture (wood), in particular, tooth grooves 5 are formed between two adjacent rivet teeth 4 in the present embodiment. The number of the rivet teeth 4 in the present embodiment is 11, and the details are not described here.
In order to prevent the fixture (wood) from being shifted, loosened, etc., specifically, the groove depth of the tooth groove 5 provided on the conical section 2 in this embodiment is gradually deepened from front to back. So as to facilitate the biting of the two rivet teeth 4 on the fixture (wood).
Specifically, the axial length of the rivet tooth 4 provided on the cylindrical section 3 in this embodiment is shorter than the axial length of the rivet tooth 4 provided on the conical section 2. The crests of the riveting teeth 4 are arc-shaped concave surfaces so as to be convenient for processing and manufacturing. Simultaneously, the riveting teeth 4 on the conical section 2 play a role in guiding and fixing.
A good fixed positioning is achieved, in particular in the present embodiment the total length of the addition of the cylindrical section 3 and the conical section 2 is shorter than the length of the bolt body section 1. The cone shape has a good guiding effect and requires a small applied force.
Specifically, in this embodiment, the diameter of the small end of the conical section 2 is larger than the diameter of the plug main body section 1, and the small end of the conical section 2 is connected to the rear end of the plug main body section 1. The design may be pushed inwardly at the small end of the conical section 2 and the rear end of the pin body section 1 to form a slug (e.g. chip) that is retained in the mounting hole so that the axis of the cylindrical section 3 and the axis of the mounting hole coincide.
Specifically, the diameter of the large head end of the conical section 2 in this embodiment is equal to the diameter of the cylindrical section 3. The rear end of the cylindrical section 3 is provided with a second chamfer so as to prevent the bolt rivet from being unable to be installed in place due to flanging when knocking.
Specifically, the chamfer 11 in this embodiment is any one of a chamfer of a slope and a chamfer of a circular arc.
The rear end of the bolt main body section is provided with a conical section and a cylindrical section connected to the rear end of the conical section, the cylindrical section is axially provided with riveting teeth, and the inner hole wall of a fixture (wood) is snapped tightly through the riveting teeth so as to ensure the stability of connection, prevent the circumferential loosening, deviation and other conditions of the fixture (wood), and the riveting teeth are lengthened on the conical section and gradually contracted from front to back so as to facilitate installation and replacement.
In addition, a cold heading forming part with a triangular cross section is arranged in the middle of the bolt main body section 1, and the triangular edge of the cold heading forming part protrudes out of the outer cylindrical surface of the bolt main body section 1. The advantage of this structure is that: and a bite is formed in the middle of the inner wall of the mounting hole so as to improve the mounting firmness. Of course, the linear distance from the edge of the cold header to the transverse cross section of the axis of the cold header is smaller than the outer diameter of the cylindrical section 3.
Although the terms of the pin body section 1, chamfer 11, conical section 2, cylindrical section 3, rivet tooth 4, tooth slot 5, etc. are used more herein, the possibility of using other terms is not precluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
