Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to a hardware screw fastener that is resistant to loosening and prevents loosening. Background Technology

[0002] When connecting parts of some mechanical equipment, hardware screws and fasteners are needed to tighten them. In the existing technology, when connecting screws and fasteners to parts, they are turned by wrench, which is inconvenient for the screws and fasteners to rotate and tighten, and is not convenient for connecting screws and fasteners to parts.

[0003] Currently, existing technology (CN218718070U) discloses a non-loosening and anti-slip hardware screw fastener, including a screw spindle, a nut fixedly installed at the top of the screw spindle, and a tapered protrusion fixedly installed at the bottom of the screw spindle. An external thread groove is formed on the outer surface of the screw spindle, and a washer is fitted on the top of the screw spindle near the lower part of the nut. A wrench groove is formed on the upper surface of the nut. An extension mechanism is connected inside the nut, and an anti-loosening mechanism is connected inside the extension mechanism near the bottom. This non-loosening and anti-slip hardware screw fastener allows for easy rotation and tightening of the screw fastener, facilitating connection between the screw fastener and parts. When the limiting pin is pulled out, the clamping post moves relative to the extension plate through an anti-loosening connector and a return spring, clamping downwards to provide support after the screw fastener is connected, thus preventing loosening of the screw fastener.

[0004] However, when using the above method, the limiting pin needs to be pulled out of the limiting hole when using screw fasteners, so that the clamping post is pushed by the return spring and then presses against the washer. However, since the clamping post is used to press against the washer, the clamping post is small in size, so after pressing against the washer, the clamping post is exposed. If it is accidentally collided with an external object, the clamping post is easily damaged, affecting the normal use of the screw fasteners. Utility Model Content

[0005] The purpose of this utility model is to provide a non-loosening and anti-slip hardware screw fastener, which aims to solve the problem that in existing non-loosening and anti-slip hardware screw fasteners, the clamping post is exposed after it abuts against the washer, and the clamping post is easily damaged after accidental collision with external objects, affecting the normal use of the screw fastener.

[0006] To achieve the above objectives, this utility model provides a non-loosening and anti-slip hardware screw fastener, including a screw spindle, a nut, and a stabilizing component. The nut is fixedly connected to the screw spindle and is located at the top of the screw spindle.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of a non-loosening and anti-slip hardware screw fastener according to this utility model. Figure 2 This is a schematic diagram of the overall structure of a non-loosening and anti-slip hardware screw fastener according to this utility model from another angle.

[0021] This utility model discloses a non-loosening and anti-slip hardware screw fastener, comprising a screw spindle 101, a nut 102, and a stabilizing component 103. The stabilizing component 103 includes an upper washer 104, a lower washer 105, a limiting frame 106, a slide rail 107, a spring 108, a plug rod 109, an auxiliary mechanism 110, a conical head 111, and an extension head 112. The plug rod 109 includes a sliding plate 113, a limiting rod 114, and a protrusion 115. The auxiliary mechanism 110 includes a serrated thread block 116 and a separator bar 117. The separator bar 117 includes a longitudinal bar 118 and a transverse bar 119. The aforementioned solution solves the problem that in existing non-loosening and anti-slip hardware screw fasteners, the clamping post is exposed after it abuts against the washer, and is easily damaged after accidental collision with external objects, affecting the normal use of the screw fastener.

[0022] In this specific embodiment, the nut 102 is fixedly connected to the screw spindle 101 and is located at the top of the screw spindle 101. By inserting a screwdriver into the nut 102 and turning the screwdriver clockwise to drive the screw spindle 101 to rotate, the screw fastener can be driven into the object to be fastened, thus fixing the two objects.

[0023] The upper washer 104 is rotatably connected to the nut 102 and located on the side of the nut 102; the lower washer 105 is fixedly connected to the upper washer 104 and located at the bottom of the upper washer 104; the limiting frame 106 is fixedly connected to the nut 102 and located on the side of the nut 102; the slide rail 107 is fixedly connected to the upper washer 104 and located on one side of the upper washer 104; and the spring 108 is connected to the slide rail. 107 is fixedly connected and located on the side of the slide rail 107. The insert rod 109 is fixedly connected to the spring 108 and slidably connected to the limiting frame 106, and is located on one side of the spring 108. The auxiliary mechanism 110 is located on one side of the screw spindle. When it is necessary to use screw fasteners to fix two objects, the worker first inserts a screwdriver into the nut 102, aligns the screw spindle 101 with the object to be fastened, and turns the screwdriver clockwise to drive the screw... The screw spindle 101 rotates, driving it into the object being fastened and pulling the insert rod 109, compressing the spring 108. Once the screw spindle 101 is fully engaged in the object, the lower washer 105 presses against it, and the upper washer 104 engages the nut 102. At this point, the operator can release the insert rod 109, and the spring 108 returns to its original position, pushing the insert rod 109 against the slide rail 1. The screw slides into the limiting frame 106 of the nut 102, locking the nut 102 in place. When the screw spindle 101 is driven into the object being fastened, the auxiliary mechanism 110 cooperates with the screw spindle 101 to fix the two objects together. This solves the problem that in existing anti-loosening hardware screw fasteners, the locking post is exposed after it abuts against the washer, and it is easily damaged after accidental collision with external objects, affecting the normal use of the screw fastener.

[0024] Secondly, the tapered head 111 is fixedly connected to the screw spindle 101 and located at the bottom of the screw spindle 101, and the extension head 112 is fixedly connected to the nut 102 and located at the top of the nut 102. By setting the tapered head 111 at the bottom of the screw spindle 101, the screw fastener can be driven into the object more easily, improving the usage effect. The extension head 112 on the nut 102 increases the contact area between the nut 102 and the screwdriver, making it easier for the operator to rotate the screw.

[0025] Furthermore, the slider 113 is slidably connected to the slide rail 107 and fixedly connected to the spring 108, and is located on one side of the spring 108. The limiting rod 114 is fixedly connected to the slider 113 and slidably connected to the limiting frame 106, and is located on the side of the slider 113. The protrusion 115 is fixedly connected to the slider 113 and is located on the top of the slider 113. After the screw spindle 101 is driven into the object, the nut 102 is close to the upper washer 104. At this time, the worker releases the protrusion 115, the spring 108 begins to reset, pushes the slider 113 to move, and thus causes the limiting rod 114 to move accordingly, so that it can slide into the limiting frame 106 and lock the nut 102.

[0026] In addition, the sawtooth thread block 116 is fixedly connected to the screw spindle 101 and located on the side of the screw spindle 101. The separator strip 117 is fixedly connected to the screw spindle 101 and the sawtooth thread block 116, and located on the side of the screw spindle 101. After the sawtooth thread block 116 of the screw spindle 101 is driven in, it can directly lock the object, improving the locking effect of the screw fastener. Furthermore, the separator strip 117 increases the friction between the sawtooth thread block 116 and the object, improving the anti-loosening effect.

[0027] Meanwhile, the longitudinal strip 118 is fixedly connected to the screw spindle 101 and located on one side of the screw spindle 101, and the transverse strip 119 is fixedly connected to the screw spindle 101 and to the sawtooth thread block 116 and located on the side of the sawtooth thread block 116. The cooperation of the longitudinal strip 118 and the transverse strip 119 can increase the friction between the sawtooth thread block 116 and the object, improve the stability of the screw spindle 101, and extend its service life.

[0028] This utility model discloses a non-loosening and anti-slip hardware screw fastener. When using the screw fastener to fix two objects, the worker first inserts a screwdriver into the nut 102, aligns the screw spindle 101 with the object to be fastened, and turns the screwdriver clockwise, causing the screw spindle 101 to rotate and drive it into the object to be fastened. The worker can then hold the protrusion 115 to move the slider 113, compressing the spring 108. After the screw spindle 101 is fully driven into the object, the lower washer 105 presses against the object, and the upper washer 104 locks the nut 102 in place. At this point, the worker can release the screw. The protrusion 115 and the spring 108 begin to reset, pushing the slider 113 to move, thereby causing the limiting rod 114 to move accordingly and slide into the limiting frame 106 to lock the nut 102. Through the cooperation of the longitudinal strip 118 and the transverse strip 119 on the serrated thread block 116, the friction between the serrated thread block 116 and the object can be increased, and the stability of the screw spindle 101 can be improved, extending its service life. This solves the problem that in existing anti-loosening hardware screw fasteners, the clamping post is exposed after it abuts the washer, and it is easily damaged after accidental collision with external objects, affecting the normal use of the screw fastener.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
