Description

Technical Field

[0001] This utility model belongs to the field of hardware tool technology, and in particular relates to a self-locking adjusting nut. Background Technology

[0002] Screws and nuts are used in various industries. In some cases, the screw is very long, and the stroke of the nut on the screw is also long. If the position of the nut needs to be adjusted, it is necessary to use tools to rotate the nut continuously to make the nut reach the specified position, which is time-consuming and inconvenient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a self-locking adjusting nut that is easy to move on a screw.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A self-locking adjusting nut, comprising:

[0006] The housing has a mounting hole in the middle and symmetrical clearance holes on the side wall of the mounting hole; a hinge seat is provided at the upper end of the housing.

[0007] A positioning block, one end of which is hinged to a hinge seat; a dial is provided on the positioning block;

[0008] A gasket, which is slidably installed in a mounting hole and can cooperate with the dial head of the positioning block;

[0009] A plunger is slidably installed in a mounting hole. A positioning pin is provided at the upper end of the plunger, and a spring that can cooperate with a gasket is fitted on the outer side of the positioning pin. A through hole is opened laterally in the middle of the plunger, and teeth that can cooperate with a screw are opened on the upper section of the inner side wall of the through hole.

[0010] Furthermore, a positioning plane is provided on one side of the plunger, and a limiting surface that can cooperate with the positioning plane is provided on the inner wall of the mounting hole.

[0011] Furthermore, the positioning block is hinged to the hinge seat using a pin.

[0012] Furthermore, an end plate is provided at the lower part of the plunger.

[0013] Furthermore, the end of the dial is configured as an arc shape.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention adjusts the relative position of the plunger and the housing, allowing the toothed through-hole on the plunger to engage with the screw at different positions. When the teeth mesh with the external thread of the screw, the plunger and screw are locked together; conversely, the plunger and screw can move freely, and the housing can also move accordingly. This facilitates adjusting the position of the nut on the screw and saves time. This invention has a simple structure, ingenious design, and strong practicality. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figures 1-3 As shown, a self-locking adjusting nut includes a housing 1, a positioning block 5, a washer 7, a plunger 8, and a screw 12. The plunger 8 is provided inside the housing 1, and the screw 12 is transversely provided through the plunger 8. After the positioning block 5 is moved, the screw 12 is locked or opened by the plunger 8.

[0022] The housing 1 has a mounting hole 2 in the middle, and relief holes 3 are symmetrically provided on the side wall of the mounting hole 2, through which the screw 12 can pass; a hinge seat 4 is provided at the upper end of the housing 1.

[0023] One end of the positioning block 5 is hinged to the hinge seat 4; a dial 6 is provided on the positioning block 5.

[0024] The gasket 7 is slidably installed in the mounting hole 2, and the gasket 7 can cooperate with the dial head 6 of the positioning block 5;

[0025] The plunger 8 is slidably installed in the mounting hole 2. A positioning post 9 is provided at the upper end of the plunger 8. A spring 10 that can cooperate with the gasket 7 is fitted on the outside of the positioning post 9. The spring 10 provides a slight force away from the gasket 7 to the plunger 8, so that the plunger 10 and the screw 12 will not easily slide.

[0026] A through hole 11 is provided in the middle of the plunger 8, and teeth 17 that can cooperate with the screw 12 are provided on the upper section of the inner side wall of the through hole 11.

[0027] The screw 12 passes through the through hole 11 and the relief hole 3. When the head 6 of the positioning block 5 is not engaged with the washer 7, the screw 12 can move freely in the through hole 11 and the relief hole 3. When the positioning block 5 is moved, the head 6 pushes down against the washer 7, and the washer 7 applies pressure to the plunger 8. The plunger 8 moves downward. At this time, the teeth 17 engage with the external thread on the screw 12, and the nut as a whole cannot move on the screw 12.

[0028] Furthermore, a positioning plane 13 is provided on one side of the plunger 8, and a limiting surface 14 that can cooperate with the positioning plane 13 is provided on the inner side wall of the mounting hole 2. The positioning surface 13 and the limiting surface 14 cooperate to prevent the plunger 8 from being installed in the wrong direction and to avoid the teeth 17 from not meshing with the external thread of the screw 12.

[0029] Furthermore, the positioning block 5 is hinged to the hinge seat 4 using a pin 15.

[0030] Furthermore, an end plate 16 is provided below the plunger 8 to prevent debris from entering between the housing 1 and the plunger 8 and to avoid jamming.

[0031] Furthermore, the end of the dial 6 is configured in an arc shape, which facilitates turning and prevents motion interference.

[0032] Working principle: When using this utility model, first place the gasket 7 into the mounting hole 2, then put the spring 10 on the outside of the positioning post 9, and mate the positioning surface 13 on the plunger 8 with the limiting surface 14 in the mounting hole 2, and insert the plunger 8 into the mounting hole 2; then, insert the screw 12 through the through hole 11 and the clearance hole 3.

[0033] When the head 6 of the positioning block 5 is not engaged with the washer 7, the screw 12 can move freely in the through hole 11 and the relief hole 3; when the positioning block 5 is moved, the head 6 presses down against the washer 7, the washer 7 applies pressure to the plunger 8, and the plunger 8 moves downward. At this time, the teeth 17 engage with the external thread on the screw 12, and the nut as a whole cannot move on the screw 12.

[0034] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
