Description

TECHNICAL FIELD

[0001] The utility model relates to the field of screw cap, specifically is a prevent loosening screw cap with cap. BACKGROUND

[0002] Screw cap is also called nut, is a fixed tool, the centre has the hole, the hole's inside has the thread. Nut often with the screw of the size is combined, to fixed relevant joint part, if the environmental factor such as vibration makes nut loose, can use glue or pin etc. further for relevant part reinforce, nut is mostly hexagonal, secondly is square.

[0003] And the existing screw cap in the use process, the anti-loosening performance needs to be improved, in the connection use process due to the mechanical vibration of equipment and easily cause the screw cap loosening, thereby there is certain risk. UTILITY MODEL CONTENTS

[0004] The utility model discloses a prevent loosening screw cap with cap to solve the problem in the background art.

[0005] In order to achieve the above object, the utility model provides the following technical scheme: a prevent loosening screw cap with cap, including screw cap, the one side of screw cap is fixedly connected with cap, and the outside screw thread of cap near screw cap one end is connected with a plurality of compression screw rod, every compression screw rod is located cap inside one end and is fixedly connected with compression arc plate, and the ring rubber pad is arranged in cap, and the outside of ring rubber pad is fixedly connected with every compression arc plate one end.

[0006] Preferably, the ring rubber pad is annular structure.

[0007] Preferably, every compression arc plate is arc structure in cross section.

[0008] Preferably, a plurality of compression screw rods are arranged perpendicularly along the outside of the cap to the outside of the cap.

[0009] Preferably, a plurality of compression screw rods are annularly distributed along the outside of the cap.

[0010] Preferably, the screw cap is internally provided with a thread groove matched with the outer thread of the fastening screw rod.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The utility model discloses a nut and fastening screw one end thread connection, then rotate every compression screw respectively make every compression screw through the thread connection process with the cap side wall, respectively drive every section arc compression arc board to fastening screw one side close, to make compression arc board drive annular rubber pad to fastening screw one side extrude, through the setting annular rubber pad extrusion in the process of compression arc board to fastening screw one side, annular rubber pad and fastening screw outside thread structure compression close fit, increase the friction of compression arc board and fastening screw, thereby improve the anti-loose performance of nut. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is the structural schematic diagram of the utility model.

[0014] In the drawing: 1, nut;2, cap;3, compression screw;4, compression arc board;5, annular rubber pad;6, screw rod. DETAILED DESCRIPTION

[0015] The technical scheme in the embodiments of the utility model will be described below clearly and completely in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor are within the protection scope of the utility model.

[0016] Embodiment one

[0017] Please refer to Figure 1 , the anti-loose nut with cap in the drawing includes nut 1, and nut 1 one side fixedly connected with cap 2, and cap 2 is close to the outside thread of nut 1 one end and is connected with several compression screws 3, and every compression screw 3 is located cap 2 inside one end and is fixedly connected with compression arc board 4, and cap 2 is provided with annular rubber pad 5, and annular rubber pad 5 outside is fixedly connected with every compression arc board 4 one end.

[0018] In the embodiment, annular rubber pad 5 is annular structure, every compression arc board 4 is section arc structure, and several compression screws 3 are along cap 2 outside and are perpendicular to cap 2 outside, and several compression screws 3 are along cap 2 outside and are annularly distributed, and the thread groove that nut 1 is opened is cooperated with fastening screw 6 outside thread.

[0019] Further, the screw cap 1 is threadedly connected with one end of the fastening screw 6, then each compression screw 3 is rotated respectively to drive each cross-section arc-shaped compression arc plate 4 to approach the fastening screw 6 side, so that the compression arc plate 4 drives the annular rubber pad 5 to be extruded to the fastening screw 6 side, the annular rubber pad 5 is tightly combined with the thread structure outside the fastening screw 6 in the extrusion process of the compression arc plate 4 to the fastening screw 6 side, the friction force between the compression arc plate 4 and the fastening screw 6 is increased, so that the anti-loose performance of the screw cap 1 is improved.

[0020] The working principle of the utility model is: the screw cap 1 is threadedly connected with one end of the fastening screw 6, then each compression screw 3 is rotated respectively to drive each cross-section arc-shaped compression arc plate 4 to approach the fastening screw 6 side, so that the compression arc plate 4 drives the annular rubber pad 5 to be extruded to the fastening screw 6 side, the annular rubber pad 5 is tightly combined with the thread structure outside the fastening screw 6 in the extrusion process of the compression arc plate 4 to the fastening screw 6 side, the friction force between the compression arc plate 4 and the fastening screw 6 is increased, so that the anti-loose performance of the screw cap 1 is improved.

[0021] It should be noted that the relational terms herein such as first and second and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any such actual relationship or order between such entities or actions.
