Description

Technical Field

[0001] The invention belongs to the technical field of nuts, and in particular relates to a nut with adjustable connection tightness and a use method thereof. Background Art

[0002] A nut is a fixing tool with a hole in the center and threads on the inside of the hole. It is often used with screws of the same size to fix the relevant joint parts. The existing nuts are stable in later use, so the nut and the screw or bolt need to be connected tightly. Therefore, it is inconvenient to rotate the nut for connection. The staff needs to make great efforts to connect it. After the nut is rotated and connected, the tightness of the connection with the bolt or screw can only be guaranteed by its own material and production process. This method is relatively unstable. For this reason, we propose a nut with adjustable connection tightness and a method of use. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a connection tightness adjustable nut and a use method, which effectively solves the above problem.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a nut with adjustable connection tightness, comprising a nut body, the nut body comprising an inner screw tube, the outer side of the inner screw tube is connected to an outer protective layer, an adjustment device is arranged in the interlayer between the inner screw tube and the outer protective layer, and through holes matching the adjustment device are opened on both sides of the left and right sides of the outer protective layer.

[0005] Preferably, the outer protective layer includes a protective tube, a first splicing block is provided on both left and right sides of the inner cavity of the protective tube, a second splicing block is provided on both front and rear sides of the inner cavity of the protective tube, the upper and lower sides of the second splicing block are connected to a first limiting plate, and the left and right sides of the first limiting plate and the front and rear sides of the second splicing block are provided with mounting screw holes.

[0006] Preferably, the adjusting devices on the left and right sides are arranged in a mirror image, and the adjusting device on the left side includes a first screw rod, a push plate is arranged on the right side of the first screw rod, and a plurality of push rods are evenly connected to the right side of the push plate.

[0007] Preferably, a second limiting plate is connected to the upper side of the inner spiral tube, a body of the second limiting plate and an upper side of the outer protective layer are provided with screw holes, and a third limiting plate is connected to the lower side of the inner spiral tube.

[0008] Preferably, a spring is arranged on the right side of the push plate, and a groove matching the spring is opened on the left side of the outer protective layer.

[0009] Preferably, handles are connected to the front and rear sides of the nut body.

[0010] Preferably, the first screw is arranged at an angle.

[0011] Preferably, the push rod is arranged at an angle.

[0012] A method for using a connection nut with adjustable tightness: The method specifically comprises the following steps:

[0013] S1: When the device is used, the push plate, the push rod and the spring are sent into the interior of the first splicing block, and then the first splicing block is sleeved on the outside of the inner screw tube, and then the push plate drives the push rod to squeeze into the inner wall of the inner screw tube, and then the two sets of second splicing blocks are respectively installed from the front side of the inner screw tube, and the second splicing block is sleeved on the outside of the inner screw tube, and then the second splicing block is connected to the first splicing block by bolts, and then the second limit plate is rotated and screwed to the upper side of the inner screw tube, and the second limit plate is connected to the protective tube by bolts, and then the position of the second limit plate is limited, and then the first screw is rotated to connect with the first splicing block, and the assembly of the nut body is completed;

[0014] S2: During use, the inner screw tube is sleeved on the outside of the screw or bolt to be used, and then moved to the predetermined position and the tightness is adjusted by the adjusting device. The device can be provided with balls in the inner screw tube to form a ball nut during production as needed, and can also be used normally as needed. When in use, after the inner screw tube moves to the predetermined position, the first screw is rotated, and the push plate is squeezed by the first screw, and then the push plate drives the push rod to penetrate into the inner screw tube to contact with other bolts or screws. At the same time, the push plate squeezes the spring, and the push plate is deformed, and then the push rod squeezes other bolts or screws to increase the contact tightness of the inner screw tube with other bolts or screws, thereby improving the connection tightness of the device with other bolts or screws. When the device needs to be moved on the outside of other bolts or screws, the first screw is rotated in the opposite direction, and then the push plate and the push rod are driven by the spring that generates elastic force due to the extrusion deformation to move away from other bolts or screws, thereby facilitating the staff to rotate the device for moving work.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting the inner screw tube and the outer protective layer, the adjustment device can be used to adjust the connection tightness of the nut and the screw or bolt connected thereto. The precision of the inner screw tube does not need to be too high during the production process. The connection tightness can be adjusted by the adjustment device in the later stage, which improves the convenience of nut production, improves the practicality of the subsequent use of the device, and increases the rotation speed of the nut during use, thereby indirectly improving the convenience and safety of using the device;

[0017] 2. The device can be assembled by arranging the outer protective layer, the second limit plate and the adjustment device, so that the device can be assembled quickly, which makes the device easy to produce quickly, reduces the machine requirements for the production of the device, and improves the economic benefits of producing the device;

[0018] 3. By setting a spring, when the device needs to move outside other bolts or screws, the first screw is rotated in the opposite direction, and then the push plate and the push rod are driven by the spring that generates elastic force due to extrusion deformation to move away from other bolts or screws, so that it is convenient for the staff to rotate the device to move;

[0019] 4. By setting the first screw rod to be inclined, the length of the first screw rod located in the protective tube is increased, and the tightness of the connection between the protective tube and the first screw rod is improved, thereby effectively preventing the first screw rod from loosening and causing the push rod to be separated from other bolts or screws, thereby improving the stability of the device. The push rod is inclined. By setting the push rod to be inclined, the length of the push rod located in the first joint block is increased, thereby improving the stability of the push rod during use, avoiding the situation where the push rod shakes and cannot effectively contact other screws or bolts, and indirectly improving the stability of the device.
