Description

Technical Field

[0001] The present invention relates to a quick-connect anti-vibration bolt. Background Art

[0002] Currently, in many places affected by vibration sources (such as motors, air flow, liquid flow, mechanical movement, etc.), there are many guard plates or maintenance hole covers that need to be installed on the equipment body frame, or temporary frames, guardrails, etc. need to be built indoors and outdoors, as well as non-load-bearing equipment parts installed at high altitudes. The current common solution is to use threaded bolts and nuts for connection, and the threaded bolt and nut connection has the following disadvantages:

[0003] (1) It is easy to be loosened and detached during vibration;

[0004] (2) These places need to be frequently disassembled for maintenance. During the disassembly process, the bolts and nuts are easily damaged and lost;

[0005] (3) The time taken to disassemble and install bolts and nuts is long, and hand fatigue is likely to occur in places where kinetic tools are inconvenient to use. Summary of the Invention

[0006] The purpose of the present invention is to provide a quick-connect anti-vibration bolt. The present invention solves the problem of bolt vibration loosening below a certain tensile value. At the same time, it is convenient for installation and disassembly, takes less time (only about 110 degrees of rotation is required), is not easily damaged for bolts and nuts, and has an extremely long service life (even up to thousands of disassembly and installation times).

[0007] The above purpose is achieved by the following technical solutions:

[0008] A quick-connect anti-vibration bolt, which comprises: a nut and a tubular screw rod. The nut is connected to the tubular screw rod. Two oblique guiding grooves are provided on the rod surface of the tubular screw rod, and the two oblique guiding grooves are arranged in opposite directions on the tubular screw rod;

[0009] Each end of the notch of each oblique guiding groove has a positioning groove in the direction opposite to the corresponding oblique guiding groove, and the notch of the oblique guiding groove extends obliquely from the bottom of the tubular screw rod.

[0010] For the quick-connect anti-vibration bolt, the nut and the tubular screw rod are integrally connected.

[0011] For the quick-connect anti-vibration bolt, a bolt rotation groove is provided at the top of the nut.

[0012] The beneficial effects achieved by the present invention are:

[0013] 1. The present invention is a connecting and pressing member, and the bolt is in a non-threaded form. Diagonal tension guiding grooves are symmetrically opened on the tubular column, and there are symmetric positioning grooves behind the guiding grooves to guide the elastic cross beam in the nut into the positioning grooves. The elastic force is used to fix the quick-connect anti-vibration bolt of the present invention on the nut. When there is vibration, under the combined action of the elastic element in the nut and the positioning groove of the bolt, the bolt is always fixed on the nut to achieve the effects of earthquake prevention and anti-loosening.

[0014] 2. The bolt of the present invention cancels the traditional thread and replaces the traditional thread with a diagonal guiding groove. The rear end of the guiding groove is composed of a positioning groove and a nut in the opposite direction of the guiding groove, which is convenient for installation and disassembly and takes less time.

[0015] 3. The present invention solves the problems of vibration loosening, time-consuming and laborious installation, and durability of non-load-bearing connecting bolts in reality. The present invention is an optimal alternative for non-load-bearing bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0027] As Figure 1 -3 shows, a quick-connect anti-vibration bolt, which comprises: a nut 1 and a tubular screw 2, the nut is connected to the tubular screw, and two inclined guiding grooves 3 are formed on the rod surface of the tubular screw, and the two inclined guiding grooves are arranged in opposite directions on the tubular screw rod; each end of the notch of the inclined guiding groove has a positioning groove 4 in the direction opposite to the corresponding inclined guiding groove, and the notch of the inclined guiding groove extends obliquely from the bottom of the tubular screw rod. For the quick-connect anti-vibration bolt, the nut and the tubular screw are integrally connected. For the quick-connect anti-vibration bolt, a bolt rotation groove 5 is formed at the top of the nut.

[0028] As Figure 4 -7 shows, during use, first insert the nut into the guard plate or the maintenance hole cover. At this time, the positioning card and the anti-loosening card on the nut are arranged between the guard plate or the maintenance hole cover, and then insert the tubular screw of the bolt into the nut. Then, use a tool such as a screwdriver to insert into the bolt rotation groove on the nut and rotate the bolt. Since the nut is processed from an elastic material tube into a local elastic part, there is an elastic cross beam at its bottom. When the elastic cross beam on the nut enters the tubular screw, due to the relative rotation of the bolt and the nut, the elastic cross beam of the nut is forced to rise along the guiding groove, and at the same time, the local elastic part in the nut is compressed. When the elastic cross beam passes through the inclined guiding groove, due to the pressure of the local elastic part, it enters the positioning groove and forces the nut to be fixed in the positioning groove. When there is vibration, after the elastic cross beam is displaced, due to the certain angle between the positioning groove and the inclined guiding groove and the certain length of the positioning groove, under the pressure of the local elastic part, the elastic cross beam of the nut will return to the positioning groove again, thus overcoming the loosening of the bolt and nut caused by vibration. During disassembly, just rotate in the opposite direction. Since the total rotation angle is only about 120 degrees, the installation is quick and convenient. At the same time, the connection between the bolt and the nut is an elastic connection, and it is not easy to damage the bolt and the nut during installation and disassembly, so the durability is greatly improved compared with ordinary bolts and nuts. It can even reach more than a thousand times of installation and disassembly.
