Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-5 drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment:
[0025] As Figures 1 to 5 shown, the present utility model discloses a new type of locking nut, including a nut body 1. An internal thread hole 11 runs through the middle of the nut body 1 from top to bottom, and a rotation control component is connected to the outer side wall of the nut body 1. The rotation control component includes an extension rod 2 extending upward. The extension rod 2 is vertically upward, and there are two such extension rods 2 arranged symmetrically. The design of the extension rod 2 expands the control distance of the nut body 1. After the nut body 1 is placed in a narrow and deep space, the user can directly rotate the nut body 1 through the extension rod 2 outside the narrow space.
[0026] Among them, the rotation control component further includes a connecting sleeve 4. The connecting sleeve 4 is detachably and fixedly connected to the outer side wall of the nut body 1, and the two extension rods 2 are symmetrically and fixedly connected to both sides of the connecting sleeve 4. That is, when the nut body 1 is used in a normal space, the rotation control component can be removed without using it.
[0027] Furthermore, in the present utility model, telescopic rods 5 are provided on both of the two extension rods 2. The telescopic rods 5 are telescopically arranged on the extension rods 2. Through the setting of the telescopic rods 5, the user can adjust the telescopic rods 5 according to the depth of the narrow space so that the telescopic rods 5 can extend out of the narrow space, so that the present utility model can be more flexibly applied to more narrow spaces with different depths.
[0028] The specific structure of the telescopic rod 5 telescopically movably arranged on the extension rod 2 is as follows: on the extension rod 2, there is a telescopic threaded hole 21 with an upward opening, the telescopic rod 5 is threadedly engaged with the telescopic threaded hole 21, and on the side wall of the extension rod 2, there is a fixing threaded hole 22 penetrating into the telescopic threaded hole 21. A screw 3 is threadedly engaged with the fixing threaded hole 22, and the screw 3 is used to form a hold on the telescopic rod 5. Further, at the upper end of the telescopic rod 5, there is a connecting head 6 bent towards one side, and a control handle 7 is fixedly connected to the connecting head 6. An axial fixing groove 51 is provided on the side wall of the telescopic rod 5. When the screw 3 is located in the fixing groove 51, the connecting heads 6 of the two telescopic rods 5 are arranged away from each other in opposite directions.
[0029] When the telescopic rod 5 is adjusted telescopically, the telescopic rod 5 can be rotated. Specifically, rotating the control handle 7 drives the telescopic rod 5 through the connecting head 6. When the telescopic rod 5 rotates, it is extended and shortened through threaded engagement. When the length adjustment of the telescopic rod 5 is almost completed, pay attention to rotating the connecting heads 6 of the two telescopic rods 5 to a position where they are arranged away from each other in opposite directions, so that the fixing groove 51 can just align with the screw 3 on the fixing threaded hole 22. By rotating the screw 3 and inserting it into the fixing groove 51 and pressing on the telescopic rod 5, reliable structural fixation between the telescopic rod 5 and the extension rod 2 is achieved. When the user needs to rotate the nut body 1 in a narrow and deep space, the two control handles 7 can be directly held simultaneously outside the narrow space for operation.
[0030] Schematic structural diagram of the connecting sleeve 4 detachably and fixedly connected to the outer side wall of the nut body 1: The connecting sleeve 4 is sleeved on the nut body 1, and the nut body 1 includes a rhombic seat 12 on the outer side wall of its lower half. The rhombic seat 12 is in clearance fit with the connecting sleeve 4, that is, there is a space in the connecting sleeve 4 that can fit the nut body 1 and the rhombic seat 12. As Figure 5 shown, this structure can prevent relative rotation between the connecting sleeve 4 and the nut body 1.
[0031] Further, an external half-threaded opening 41 is provided on the upper end surface of the connecting sleeve 4, and an internal half-threaded opening 13 corresponding to the external half-threaded opening 41 is provided on the upper end surface of the nut body 1. The external half-threaded opening 41 and the internal half-threaded opening 13 can just form a complete threaded opening. An internal hexagon screw 83 is provided between the connecting sleeve 4 and the nut body 1 and is threadedly engaged between the external half-threaded opening 41 and the internal half-threaded opening 13. The internal hexagon screw 83 can be engaged in the threaded opening formed by the external half-threaded opening 41 and the internal half-threaded opening 13 to achieve the fixation between the connecting sleeve 4 and the nut body 1.
[0032] In the present utility model, a limiting ring 14 is integrally formed at the lower end of the nut body 1. A plurality of through openings 141 are circumferentially formed on the limiting ring 14. When the connecting sleeve 4 is sleeved outside the nut body 1, it abuts against the limiting ring 14. The through openings 141 on the limiting ring 14 can be fixed on the surface of the object to be locked by small screws 3 when the nut body 1 is used separately from the connecting sleeve 4, so as to realize the fixation of the nut body 1 and the object to be locked.
[0033] Meanwhile, it should be pointed out that the terms used in the present utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the protection scope of the present utility model.
[0034] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
