Description

Technical Field

[0001] This utility model relates to the field of nut column structure technology, and more specifically, to a locking and positioning nut column. Background Technology

[0002] A locating nut post is a fastener used to install on sheet metal or thin plates. By fixing the locating nut to the thin plate, a fixed internal thread is formed on the thin plate, which facilitates the connection of the threaded post.

[0003] However, the existing nut post has the following problems when used:

[0004] In traditional nut-post connections, the connection between the ordinary nut and the post relies solely on the friction of the threads to maintain a tight fit. However, in real-world applications, especially under complex conditions such as vibration and impact, ordinary nut-post connections are prone to loosening. This can lead to misalignment between components, severely affecting the normal operation of equipment and potentially causing safety accidents.

[0005] This utility model can achieve a stable connection and precise positioning through the threaded connection between the column and the nut, the use of washers to increase friction and buffer, and the cooperation of the locking block and the positioning pin. This not only prevents the nut from loosening, rotating or shifting under various external forces, but also facilitates the removal of constraints by operating the pulling block and the positioning pin during disassembly, allowing the nut to be unscrewed, which is convenient for equipment inspection and maintenance. Summary of the Invention

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a locking and positioning nut post.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a locking and positioning nut post, comprising: a post body, a nut threadedly connected to the surface of the post body, a washer movably connected between the nut and the post body, a locking block embedded in the front side of the upper end of the nut, a positioning pin embedded in the rear of the locking block, the locking block being composed of a pull block, a fixing block, a connecting rod, a base plate and a spring, and the positioning pin being composed of a fixing plate, a positioning rod, a fixing rod, a base plate and a insertion rod.

[0008] A further preferred embodiment: the surface of the column is provided with external threads, the upper end of the column is provided with a slot, the middle of the external threads is provided with a positioning hole, the column is threadedly connected to the nut through the external threads, the slot is matched with the card block, and the base plate is embedded in the slot.

[0009] A further preferred embodiment: the positioning hole has an insertion hole inside, the positioning hole is matched with a positioning pin, the bottom of the positioning pin is embedded in the positioning hole for connection, and the insertion rod is embedded in the insertion hole for connection.

[0010] Further preferred: the nut is internally threaded, and the internal thread is arranged in conjunction with the external thread.

[0011] Further preferred: the pull block is movably mounted on the upper end of the nut, the fixed block is fixedly mounted inside the nut, the bottom of the pull block is fixedly connected with the connecting rod, the bottom of the connecting rod penetrates through the fixed block and is fixedly connected with the bottom plate, the surface of the connecting rod is fixedly mounted with a spring, and the spring is located between the bottom plate and the fixed block.

[0012] Further preferred: the bottom of the fixed disc is fixedly connected with the positioning rod on the left and right sides, the fixed rod is between the positioning rods, the bottom of the fixed rod is fixedly connected with the bottom disc, and the bottom of the bottom disc is fixedly connected with the insertion rod. Beneficial effects

[0013] 1. By setting the clamping groove and the clamping block, when the nut rotates upward along the thread of the column, the clamping block moves with the nut, when the nut rotates to the position corresponding to the clamping groove and the clamping block on the column, at this time the clamping block is quickly embedded in the clamping groove under the elastic force of the spring in it, this embedding action accurately positions the nut on the column, so that the nut is firmly constrained in the horizontal direction, effectively preventing displacement of the nut on the column, at the same time, due to the close fit of the clamping block and the clamping groove, the rotational freedom of the nut is limited, thereby avoiding rotation of the nut on the column. During equipment operation, whether subjected to vibration, impact, or other complex external forces, the close combination of the clamping block and the clamping groove can continue to play a role, ensuring stable connection and maintaining the overall structural stability of the equipment. When the equipment needs to be disassembled and repaired, only the pull block connected with the clamping block needs to be manually pulled, the pull block drives the clamping block to overcome the elastic force of the spring, so that the clamping block is separated from the clamping groove. Once the clamping block is separated from the clamping groove, the positioning restriction of the nut in the horizontal direction is removed, and subsequent steps such as rotating the nut down from the column can be smoothly carried out.

[0014] 2. By setting the positioning hole, the insertion hole and the positioning pin, when the nut rotates to the predetermined position and the clamping block is preliminarily positioned, the positioning pin begins to play a key role. The bottom of the positioning pin is aligned with the positioning hole on the column, and the insertion rod at the bottom of the positioning pin can be inserted into the positioning hole by force, and then accurately embedded in the insertion hole. The fixed disc, positioning rod, fixed rod and bottom disc of the positioning pin cooperate with each other to ensure that the insertion rod is stably and accurately in place. This process further strengthens the connection stability of the nut and the column. The positioning hole and the insertion hole provide accurate guidance and positioning basis for the positioning pin, so that the positioning pin can be accurately installed, effectively preventing the nut from rotating. When disassembling, only the fixed disc of the positioning pin needs to be pulled upwards to drive the insertion rod to separate from the insertion hole and the positioning hole. The removal of the positioning pin removes the restriction on the rotation of the nut, creating conditions for easily rotating the nut down and completing the disassembly work, greatly improving the convenience and efficiency of equipment maintenance.

[0015] 3. By setting the gasket, when the nut begins to screw on the column, the gasket is placed between the nut and the column, and as the nut is tightened, the gasket is extruded, and due to its elasticity, an elastic force is generated during compression, which continuously exerts axial pressure on the nut, thereby significantly increasing the friction between the nut and the column threads, providing a certain anti-loosening guarantee for the initial connection.

[0016] 4. As described above, the locking positioning nut column is provided with structures such as the clamping groove, the positioning hole, the insertion hole, the clamping block, the positioning pin and the gasket, and when installing, the nut is screwed to drive the clamping block to move, and when the clamping groove corresponds to the clamping block, the clamping block is embedded in the clamping groove to preliminarily position the nut and prevent displacement, at the same time, the positioning pin is inserted into the positioning hole and the insertion hole to further stabilize the connection and prevent the nut from rotating, and the gasket is extruded between the nut and the column to generate an elastic force to increase the friction and provide anti-loosening protection. In work, the gasket buffers external force impact and reduces wear and tear, continuously prevents loosening, the clamping block and the positioning pin maintain the stable connection of the nut and the column, and when disassembling, the clamping block and the positioning pin are removed, and due to the good elasticity of the gasket, the nut is not hindered from being screwed down, facilitating equipment maintenance.

[0023] Please refer to Figures 1-4The utility model discloses a locking and positioning nut post, comprising: post 1, the surface threaded connection of post 1 has nut 2, the movable joint of nut 2 and post 1 has washer 3 between, nut 2 upper end front side inserts and installs clamping block 202, clamping block 202 rear insert installs positioning pin 203, clamping block 202 is by pull block 204, fixed block 205, connecting rod 206, bottom plate 207 and spring 208 are constituted, positioning pin 203 is by fixed disc 209, positioning rod 210, fixed rod 211, bottom disc 212 and plug rod 213 are constituted, the surface of post 1 is provided with outer thread 101, and the upper end of post 1 is provided with clamping groove 102, and the middle part of outer thread 101 is provided with positioning hole 103, and post 1 is connected by outer thread 101 and nut 2 screw, and clamping groove 102 is set with clamping block 202, and bottom plate 207 inserts and sets up inside clamping groove 102, and the inside of nut 2 is provided with inner thread 201, and inner thread 201 is set with outer thread 101, first, post 1 is connected by the surface threaded connection of outer thread 101 and nut 2, because inner thread 201 is set with outer thread 101, can be by rotating nut 2, make it gradually move upwards along the outer thread 101 of post 1, in this process, washer 3 is located between nut 2 and post 1, play the role of buffering and prevent nut 2 loosening, and washer 3 is rubber material, possess certain elasticity, when nut 2 is tightened, washer 3 will be compressed, produce a rebound force, this force can continuously exert an axial pressure to nut 2, thereby increase the friction between nut 2 and post 1, prevent nut 2 loosening.When the nut 2 is rotated to the appropriate position, that is, the clamping groove 102 at the upper end of the column 1 corresponds to the clamping block 202 embedded and installed on the front side of the upper end of the nut 2, the clamping block 202 begins to play a role, the bottom plate 207 in the clamping block 202 is embedded inside the clamping groove 102, at this time, the spring 208 in the overall structure of the clamping block 202 is in a compressed state, generating a pushing force to the clamping groove 102 inside the pull block 204 and the fixed block 205, so that the clamping block 202 can be stably clamped in the clamping groove 102, thereby preliminarily positioning the nut 2 and the column 1. After the clamping block 202 completes the preliminary positioning, the rear positioning pin 203 begins to work, the insertion rod 213 in the positioning pin 203 is inserted into the positioning hole 103 opened in the middle of the external thread 101 of the column 1, and the fixed disc 209, the bottom disc 212 and the fixed rod 211 of the positioning pin 203 structure play a supporting and positioning role, ensuring that the insertion rod 213 is accurately inserted into the positioning hole 103 and maintains a stable connection state. Through the insertion of the positioning pin 203, the stability of the connection between the nut 2 and the column 1 is further enhanced, preventing the nut 2 from rotating or moving on the column 1. During normal operation of the equipment, the connection between the nut 2 and the column 1 needs to withstand various external forces, such as vibration, tension, pressure, etc. The clamping block 202 clamped in the clamping groove 102 limits the displacement of the nut 2 in the horizontal direction, preventing it from moving horizontally on the column 1. At the same time, the insertion rod 213 of the positioning pin 203 is inserted into the positioning hole 103, further preventing the nut 2 from rotating, ensuring the stability of the relative position between the nut 2 and the column 1. The washer 3 continuously plays a buffering role during work, reducing the wear between the nut 2 and the column 1 caused by external impact, and increasing the friction between the two, which helps to prevent the nut 2 from loosening. When disassembling, first, the positioning pin 203 needs to be removed from the positioning hole 103 of the column 1. By applying an external force to pull the fixed disc 209 of the positioning pin 203 upwards, the insertion rod 213 is separated from the positioning hole 103, which removes the restriction of the positioning pin 203 on the rotation of the nut 2. Then, the clamping block 202 is operated by pulling the pull block 204, further compressing the spring 208, driving the fixed block 205 and the bottom plate 207 to move out of the clamping groove 102. At this time, the clamping state of the clamping block 202 and the clamping groove 102 is released, and the nut 2 is no longer limited in the horizontal direction. After the positioning pin 203 and the clamping block 202 are both released, the nut 2 can be rotated to move downward along the external thread 101 of the column 1, thereby rotating the nut 2 off the column 1, completing the disassembly process.
