Description

Technical Field

[0001] The utility model relates to the technical field of clip nuts, in particular to a clip-on locking nut. Background Art

[0002] A captive nut, also known as a floating nut, is a component that houses a nut in a freely movable manner inside a shell body welded to the vehicle body. This freely movable nut absorbs axial misalignment between the bolt and the nut when the accessory is secured to the vehicle body, making it easy to tighten without causing assembly deviation.

[0003] When installing the clip nut, the square nut needs to be placed in the slot plate. In order to maintain stability, the nut needs to be limited. The traditional limiting method of the clip nut is mostly to set metal sheets at both ends of the slot plate. After the nut is placed, the metal sheet is bent so that the metal sheet is vertically upward, thereby limiting the nut in the slot plate. However, this method requires bending the metal sheet when replacing the nut, which is not only time-consuming and labor-intensive, but also the metal sheet and the slot plate are rigidly connected. Bending for a long time can easily cause breakage, resulting in damage to the slot plate. Therefore, the utility model proposes a clip-on locking nut to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a snap-on locking nut. By setting a tightening mechanism, the two bolts are rotated so that the upper end of the nut body is pressed against the top of the inner part of the slot plate body. When disassembling, the movable plate is moved downward to take out the square nut body. It is convenient to take and put the square nut body, and the slot plate body will not be damaged if used for a long time.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A snap-on locking nut comprises a slot plate body and a screw body, the slot plate body being U-shaped, a square nut body being arranged inside the slot plate body, a tightening mechanism being arranged inside the slot plate body for tightening the square nut body, the tightening mechanism comprising a movable plate slidably connected to the slot plate body, the square nut body being placed at the upper end of the movable plate, the lower end of the movable plate being rotatably connected to two symmetrically arranged bolts, both of the bolts passing through the lower end of the slot plate body and being threadedly connected thereto, and a limiting mechanism being arranged at the inner top of the slot plate body for limiting the square nut body.

[0007] Preferably, the limiting mechanism includes four L-shaped limiting plates fixedly connected to the top of the slot plate body, and the four L-shaped limiting plates are distributed in a rectangular shape.

[0008] Preferably, four limiting rods are fixedly connected between the inner top and the inner bottom of the trough plate body, the four limiting rods are distributed in a rectangular shape, and all of the four limiting rods pass through the movable plate and are slidably connected thereto.

[0009] Preferably, the lower ends of the two bolts are fixedly connected to handles, and the two handles are covered with anti-slip rubber sleeves.

[0010] Preferably, two U-shaped clamping plates are fixedly connected to the upper end of the trough plate body, and the two U-shaped clamping plates are symmetrically arranged.

[0011] Preferably, a through hole is provided at the lower end of the slot plate body, and a nut is provided at the lower end of the screw body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting a tightening mechanism, in the initial state, the lower end of the movable plate contacts the inner bottom of the slot plate body. At this time, the square nut body can be placed on the upper end of the movable plate in the slot plate body from the side opening. After the placement is completed, the two bolts are rotated at the same time. The two bolts move upward during the rotation, pushing the movable plate up, driving the square nut body to move upward until the upper end of the square nut body is tightened against the inner top of the slot plate body. When disassembling, loosen the bolts to move the movable plate downward, and the square nut body can be taken out. It is convenient to take and place the square nut body, and long-term use will not cause damage to the slot plate body.

[0014] 2. By setting a limiting mechanism, the four L-shaped limiting plates are distributed in a rectangular shape, and the four L-shaped limiting plates cooperate with the four corners of the square nut body. After tightening, the square nut body is prevented from sliding out from the side of the slot plate body, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
