Abstract
Description
Technical Field
[0001] This utility model relates to the field of fastener technology, and in particular to a pull-out metal fastener. Background Technology
[0002] Fasteners are a very common type of hardware connector used to connect and fix structures. Currently, fasteners have fixed structures and can only be used to fasten structures of a single specification, resulting in limited compatibility and low versatility. Utility Model Content
[0003] The technical problem to be solved by this utility model is that the current fasteners have a fixed structure and can only be adapted to a single specification of structure fastening, resulting in a limited range of adaptability and low versatility.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a pull-out metal fastener, including a metal mounting back plate, wherein the metal mounting back plate has lateral protrusions on both sides protruding to the same side, and the lateral protrusions are provided with strip-shaped telescopic assembly ports near the middle end of the metal mounting back plate. The metal mounting back plate is provided with an elastic metal assembly plate on the same side as the lateral protrusions. The two ends of the elastic metal assembly plate are inserted into the inside of the strip-shaped telescopic assembly ports and connected to the lateral protrusions. An inner limiting plate for locking the elastic metal assembly plate is provided inside the lateral protrusions, and a lateral locking bolt for controlling the inner limiting plate is mounted on the lateral protrusions.
[0005] The elastic metal assembly plate has strip-shaped transition openings at both ends.
[0006] The inner limiting plate has an internally threaded adjusting seat that protrudes towards the strip-shaped transition opening on its side wall.
[0007] The side wall of the internal thread adjusting seat is provided with a lateral limiting notch that matches the strip transition opening.
[0008] The metal mounting back plate has notches on both sides for mounting bolts.
[0009] A sliding limiting plate for limiting the lateral locking bolt is slidably fitted on the outer side surface of the lateral boss.
[0010] The beneficial effects of this utility model are:
[0011] (1) The pull-out metal fastener of this utility model is composed of a metal mounting back plate and an elastic metal assembly plate. Through the variable structure design, it can be adapted to different connection mechanisms, with a wide range of applications and strong versatility.
[0012] (2) The detachable structure design reduces the cost of later maintenance and replacement;
[0013] (3) The internal thread adjusting seat is controlled to move inside the lateral boss by the side locking bolt, so as to make stepless adjustment, with a wider limit range and a more stable structure. Attached Figure Description
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0015] Figure 1 This is a schematic diagram of the structure of this utility model.
[0016] Figure 2 This is a schematic diagram of the internal structure of this utility model. Detailed Implementation
[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] Figure 1 and Figure 2 The pull-out metal fastener shown includes a metal mounting back plate 1. The metal mounting back plate 1 has lateral protrusions 2 on both sides that protrude to the same side. The lateral protrusions 2 are provided with strip-shaped telescopic assembly ports near the middle end of the metal mounting back plate 1. The metal mounting back plate 1 is provided with an elastic metal assembly plate 3 on the same side as the lateral protrusions 2. The two ends of the elastic metal assembly plate 3 are inserted into the strip-shaped telescopic assembly ports and connected to the lateral protrusions 2. The lateral protrusions 2 are provided with inner limiting plates 4 for locking the elastic metal assembly plate 3. Lateral locking bolts 5 for controlling the inner limiting plates 4 are mounted on the lateral protrusions 2.
[0020] To facilitate positioning, the elastic metal assembly plate 3 has strip-shaped transition openings 6 at both ends.
[0021] To facilitate adjustment, the inner limiting plate 4 has an internally threaded adjusting seat 7 that protrudes towards the strip-shaped transition opening 6 on its side wall.
[0022] To improve the limiting effect, a lateral limiting notch 8 is provided on the side wall of the internal thread adjusting seat 7 to cooperate with the strip transition port 6.
[0023] The lateral limiting notch 8 is used to limit the movement of the strip transition port 6. Then, the lateral locking bolt 5 is rotated to drive the internal thread adjusting seat 7 to move horizontally. The outward movement of the internal thread adjusting seat 7 pulls the elastic metal assembly plate 3 outward, thereby ensuring the fit and firmness of the assembly.
[0024] To facilitate lateral assembly, notches 9 for mounting bolts are provided on both sides of the metal mounting back plate 1.
[0025] In order to enhance the limiting ability of the lateral locking bolt 5 and prevent it from loosening due to self-rotation, a sliding limiting plate 10 for limiting the lateral locking bolt 5 is slidably mounted on the outer side surface of the lateral boss 2.
[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
