Description
TECHNICAL FIELD
[0001] The utility model relates to fastener technical field especially is related to a screw lock structure. BACKGROUND
[0002] In the prior art, screw lock structure is widely used in the assembly process of various mechanical equipment, electronic products and daily necessities to realize the firm connection between components. However, the traditional screw lock method often has problems such as low installation efficiency, insufficient positioning accuracy and easy loosening, which limits the reliability and service life of the product to some extent.
[0003] Specifically, the traditional screw lock structure usually only relies on the cooperation of the screw and the threaded hole to realize the connection. In the installation process, the operator needs to spend a lot of time and effort to ensure the alignment of the screw and the threaded hole, and due to the lack of rotation stopping design, when the screw is screwed in, the screw column follows the rotation, so that the assembly is not in place.
[0004] Therefore, it is necessary to design a screw lock structure to solve the above problems. CONTENT OF THE UTILITY MODEL
[0005] The utility model aims at the deficiencies of prior art, and provides a screw lock structure.
[0006] The technical scheme of the utility model is: a screw lock structure, comprising a screw, a bracket and a screw column, the middle part of the bracket is provided with a through hole for the screw to pass through, the middle part of the screw column is provided with a threaded hole matched with the screw, and the bottom of the bracket is provided with a positioning part for positioning and rotation stopping of the screw column.
[0007] The positioning part comprises two rotation stopping protrusions arranged symmetrically, and the two sides of the screw column are symmetrically provided with fins in contact with the rotation stopping protrusions.
[0008] The positioning part further comprises two guide protrusions arranged symmetrically, the guide protrusions and the rotation stopping protrusions form a containing space of the screw column, and when the screw column is positioned in the containing space, the threaded hole on the screw column is aligned with the through hole in the middle part of the bracket.
[0009] The guide protrusion is in the shape of a slope.
[0010] The screw is a metal piece.
[0011] The bracket and the screw column are plastic pieces.
[0012] The utility model discloses the following beneficial effects are obtained: the utility model discloses the bottom of support is equipped with the positioning portion for the screw post positioning and rotation stopping, thereby can be to screw post accurate positioning and rotation stopping, thereby facilitate the screw and spin, not only improved the convenient operation, improved the assembly efficiency, and the assembly precision also obtained the stable guarantee, and there is no assembly not in position situation. BRIEF DESCRIPTION OF DRAWINGS
[0013] In order to make the content of the utility model more easily be clearly understood, the following according to specific embodiment and combining with the drawings, the utility model is further detailed.
[0014] Figure 1 It is the structural schematic diagram of the utility model.
[0015] Figure 2 It is the support bottom structural schematic diagram of the utility model.
[0016] The reference numeral in the drawing is:
[0017] Screw 1, support 2, screw post 3, through -hole 4, screw hole 5, positioning portion 6, rotation stopping boss 6-1, guide boss 6-2, fin 7. PREFERRED EMBODIMENT
[0018] (Example 1)
[0019] See Figure 1 And Figure 2 The screw locking structure of the embodiment includes a screw 1, a support 2 and a screw post 3. The middle part of the support 2 is provided with a through-hole 4 for the screw 1 to pass through. The middle part of the screw post 3 is provided with a screw hole 5 for cooperating with the screw 1. The bottom of the support 2 is provided with a positioning portion 6 for positioning and rotation stopping of the screw post 3. The embodiment realizes the quick and accurate alignment of the screw 1 and the screw post 3. In particular, the positioning portion 6 at the bottom of the support 2 is designed to include symmetrically arranged rotation stopping bosses 6-1 and guide bosses 6-2, which not only ensures the accurate positioning of the screw post 3 during installation, but also effectively prevents the rotation of the screw post 3, thereby greatly improving the installation efficiency and accuracy.
[0020] Further, the positioning portion 6 includes two symmetrically arranged rotation stopping bosses 6-1. The two sides of the screw post 3 are symmetrically provided with fins 7 in contact with the rotation stopping bosses 6-1.
[0021] Further, the positioning part 6 further comprises two guide protrusions 6-2 arranged symmetrically; the guide protrusions 6-2 and the rotation-stopping protrusion 6-1 form a containing space for the screw column 3; when the screw column 3 is positioned in the containing space, the threaded hole 5 on the screw column 3 is aligned with the through hole 4 in the middle of the support 2. The rotation-stopping protrusion 6-1 in the positioning part 6 is in close contact with the fin 7 on the screw column 3, effectively preventing the screw column 3 from loosening after locking; this design not only improves the stability of the connection, but also prolongs the service life of the product. At the same time, the slope-shaped design of the guide protrusion 6-2 makes the screw column 3 more smoothly enter the containing space during installation, further enhancing the reliability of the connection.
[0022] Further, the guide protrusion 6-2 is slope-shaped, so as to stably guide the screw column 3 to the assembly position.
[0023] Further, the screw 1 is a metal piece.
[0024] Further, the support 2 and the screw column 3 are plastic pieces. In the screw locking structure of the embodiment, the screw 1 is made of a metal piece, ensuring its strength and durability; while the support 2 and the screw column 3 are made of plastic pieces, not only reducing the manufacturing cost, but also reducing the overall weight. This material combination not only meets the performance requirements of the product, but also effectively controls the cost.
[0025] Since the embodiment improves the installation efficiency and connection stability of the screw locking structure, users can experience more convenient and reliable operation experience during installation and use, which helps to improve the satisfaction and loyalty of users to the product.
[0026] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the utility model, and it should be understood that the above description is only for specific embodiments of the utility model and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
