Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning nut post technology, and more specifically, to a locking type positioning nut post with anti-loosening properties. Background Technology
[0002] A locating nut post is a component used for mechanical connection and assembly. It not only has the connection function of a regular nut post, but also has a precise positioning function. Structurally, it is generally a post with internal threads. The external shape and size of the post are designed according to positioning requirements. With the continuous improvement of the degree of automation in modern industry, higher requirements are placed on the installation efficiency and quality stability of nut posts. However, in the process of use, traditional locating nut posts do not have a good locking effect on threaded posts, which can easily cause the threaded posts to loosen.
[0003] To address the aforementioned issues, particularly the poor locking effect of traditional positioning nut posts on threaded posts during use, which can easily lead to loosening of the threaded posts, extensive research revealed a locking anti-loosening positioning nut post with patent publication number CN216895281U. This device, belonging to the field of positioning nut posts, uses a pull-out rod to extend a moving plate, releasing the locking spring and causing the locking plate to move. When the threaded post enters the nut post body, releasing the pull-out rod allows the locking spring to cause the moving plate to move inward, engaging with the outer side of the internal threaded post. The spring then secures the threaded post inside the nut post body, preventing it from loosening.
[0004] However, the aforementioned anti-loosening locking type positioning nut post still has some problems. For example, when disassembling or assembling the threaded rod, the locking plate needs to be retracted into the main body of the nut post by controlling the pull-out rod to achieve the disassembly or assembly of the threaded rod. Furthermore, due to the locking spring, the user needs to continuously fix the position of the pull-out rod to restrict the position of the locking plate, which brings certain inconvenience to disassembling or assembling the threaded rod. To address these problems, this utility model proposes an anti-loosening locking type positioning nut post. Utility Model Content
[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a locking and anti-loosening positioning nut post.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a locking nut post with anti-loosening features, comprising a nut post body and an angle plate, wherein an installation groove is formed at the opening of the nut post body, the installation groove being an annular structure extending along the circumference of the nut post body, and a locking assembly for locking a threaded rod is provided within the installation groove, the locking assembly comprising:
[0007] An elastic block is fixedly connected in the mounting groove. The elastic block is an annular structure that can fit the threaded rod. Multiple locking blocks that limit the movement of the threaded rod are fixedly connected to one end of the elastic block facing the threaded rod. Both the locking blocks and the elastic block are made of elastic material. The locking block has a hollow structure inside. The elastic block defines a cavity inside. The elastic block has a connecting channel that communicates with the cavity and an air supply channel that communicates with the multiple elastic blocks respectively.
[0008] An extrusion block is movably disposed within the mounting groove and fixedly connected to the top of the elastic block. The extrusion block is an annular structure that matches the mounting groove.
[0009] A further preferred embodiment: a plurality of the locking blocks are arranged to extend along the connection direction between the nut column body and the threaded rod.
[0010] A further preferred embodiment: the elastic block has an embedded movable groove that allows the locking block to deform.
[0011] A further preferred embodiment: the locking block has a triangular structure.
[0012] A further preferred embodiment: a raised ring is fixedly connected to the top of the extrusion block, the raised ring protrudes towards the end opposite to the extrusion block, and the raised ring has a ring structure.
[0013] A further preferred embodiment: a connecting block is fixedly connected between the elastic block and the compression block, and a first auxiliary block and a second auxiliary block are fixedly connected between the connecting block and the elastic block and the compression block, respectively. A receiving groove for receiving the second auxiliary block is provided on the nut column body, and the compression block is movably disposed in the receiving groove. The receiving groove and the mounting groove are connected.
[0014] A further preferred embodiment: a sponge block is fixedly connected between the connecting block and the first auxiliary block, and the sponge block is fitted into the inner wall of the receiving groove.
[0015] A further preferred embodiment: a second anti-slip pad and a first anti-slip pad are fixedly connected to the nut column body and the corner plate respectively, and a plurality of anti-slip balls are fixedly connected to the second anti-slip pad.
[0016] Beneficial effects:
[0017] 1. By incorporating a locking assembly, the threaded rod is effectively limited, improving the anti-loosening performance of the nut post. This also increases the efficiency of disassembling and assembling the nut post and the threaded rod, enhancing the convenience of the device. Furthermore, the design of the annular elastic block and locking block ensures a more uniform clamping and locking effect on the threaded rod, providing a stable anti-loosening effect under various working environments, such as vibration, impact, and temperature changes.
[0018] 2. By setting up movable grooves and raised rings, the movable grooves provide additional deformation space for the locking block, allowing it to adjust its shape according to the force applied to maintain the clamping force on the threaded rod. The triangular structure of the locking block makes it easier to match the thread groove of the threaded rod, thereby improving the locking effect. The raised rings make it easier for the threaded rod to apply pressure to the elastic block.
[0019] 3. By setting up a connecting block, a sponge block, a first auxiliary block, and a second auxiliary block, the movement of the elastic block and the extrusion block becomes more stable and coordinated through the connection of the connecting block and the two auxiliary blocks. The movement of the second auxiliary block in the support groove provides guidance and support for the movement of the extrusion block, ensuring that the movement direction and range of the extrusion block meet the design requirements. The sponge block can play a role in buffering and shock absorption, and can also fill any gaps that may exist in the support groove, preventing dust, impurities, etc. from entering the support groove and affecting the movement of the extrusion block.

[0026] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.
[0027] Please see Figure 1-5 In this embodiment of the present invention, a locking type positioning nut post includes a nut post body 1 and an angle plate 2. An installation groove 12 is formed at the opening of the nut post body 1. The installation groove 12 is an annular structure extending along the circumference of the nut post body 1. A locking assembly 9 for locking a threaded rod is provided within the installation groove 12. The locking assembly 9 includes an elastic block 92, which is fixedly connected within the installation groove 12. The elastic block 92 is an annular structure that conforms to the threaded rod, and one end of the elastic block 92 directly opposite the threaded rod is fixedly connected. There are multiple locking blocks 96 that limit the threaded rod. Both the locking blocks 96 and the elastic blocks 92 are made of elastic material. The locking blocks 96 have a hollow structure inside. The elastic blocks 92 define a cavity 93 inside. The elastic blocks 92 have a connecting channel 94 that communicates with the cavity 93, and an air supply channel 95 that connects the connecting channel 94 to the multiple elastic blocks 92 respectively. The extrusion block 91 is movably set in the mounting groove 12 and fixedly connected to the top of the elastic block 92. The extrusion block 91 is a ring structure that matches the mounting groove 12.
[0028] Specifically, when the threaded rod is screwed into the nut column body 1, the locking block 96 does not obstruct the entry of the threaded rod. The threaded rod is locked as it penetrates deeper into the nut column body 1. The tail end of the threaded rod contacts the compression block 91. As the threaded rod continues to penetrate deeper into the nut column body 1, the tail end of the threaded rod drives the compression block 91 to compress the elastic block 92, causing the elastic block 92 to deform under force. Simultaneously, during the compression of the elastic block 92, the air inside its internal cavity 93 is discharged to multiple locking blocks 96 through the connecting channel 94 and the air supply pipe, causing the locking blocks 96 to deform towards the threaded rod and embed into the threaded rod. Within the groove, the threaded rod is locked in place. At this point, the threaded rod and the nut column body 1 are installed. The overall structure and operation steps are simple, providing an innovative anti-loosening structure. Utilizing the elastic deformation characteristics of the elastic block 92 and the locking block 96, the threaded rod is effectively limited, improving the anti-loosening performance of the nut column. At the same time, it improves the efficiency of disassembling and assembling the nut column body 1 and the threaded rod, enhancing the convenience of the device. Furthermore, the annular design of the elastic block 92 and the locking block 96 makes the clamping and locking effect on the threaded rod more uniform, providing a stable anti-loosening effect under different working environments, such as vibration, impact, and temperature changes.
[0029] It should be noted that, in this embodiment, a portion of the top of the elastic block 92 is reserved that is not fixedly connected to the nut column body 1, so as to ensure that the deformation of the elastic block 92 can compress the air inside the cavity 93; at the same time, in order to avoid the phenomenon of unbalanced air pressure in the nut column body 1 when the elastic block 92 locks the threaded rod, a through hole can be provided at the bottom of the threaded groove of the nut column body 1 to balance the overall air pressure and ensure the connection between the threaded rod and the nut column body 1; secondly, the materials of the elastic block 92 and the locking block 96 can be selected according to the actual situation, such as rubber, silicone, etc.; furthermore, in this embodiment, some air is pre-injected into the cavity 93 to ensure the normal operation of the device; secondly, the connection and installation method between the threaded rod, the angle plate 2 and the nut column body 1 can be referred to the publication document with patent publication number CN216895281U, which will not be described here.
[0030] In this embodiment of the utility model, such as Figure 3 and Figure 4 As shown, multiple locking blocks 96 extend along the connection direction between the nut column body 1 and the threaded rod. The elastic block 92 has an embedded movable groove 13 that allows the locking blocks 96 to deform. The locking blocks 96 have a triangular structure. Specifically, when the threaded rod is screwed in and contacts the locking blocks 96, the locking blocks 96 can deform to a certain extent in the movable groove 13 due to the pressure of the threaded rod. This allows the locking blocks 96 to better fit the threaded rod. Furthermore, when subjected to external vibration or impact, the movable groove 13 provides additional deformation space for the locking blocks 96, enabling them to adjust their shape according to the force applied to maintain the clamping force on the threaded rod. The triangular structure of the locking blocks 96 makes it easier to match the thread groove of the threaded rod, thereby improving the locking effect.
[0031] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a protruding ring 5 is fixedly connected to the top of the extrusion block 91. The protruding ring 5 protrudes towards the end opposite to the extrusion block 91, and the protruding ring 5 has a ring structure. Specifically, the protruding ring 5 makes it easier for the threaded rod to apply pressure to the elastic block 92.
[0032] In this embodiment of the utility model, such as Figure 3 , Figure 4 and Figure 5As shown, a connecting block 8 is fixedly connected between the elastic block 92 and the compression block 91. A first auxiliary block 10 and a second auxiliary block 11 are fixedly connected between the connecting block 8 and the elastic block 92 and the compression block 91, respectively. A receiving groove 14 for receiving the second auxiliary block 11 is provided on the nut column body 1. The compression block 91 is movably disposed in the receiving groove 14. The receiving groove 14 and the mounting groove 12 are connected. Specifically, when the compression block 91 moves in the receiving groove 14, the movement of the elastic block 92 and the compression block 91 is made more stable and coordinated through the connection of the connecting block 8 and the two auxiliary blocks. The movement of the second auxiliary block 11 within the receiving groove 14 provides guidance and support for the movement of the extrusion block 91, ensuring that the direction and range of movement of the extrusion block 91 meet the design requirements. Furthermore, a sponge block 7 is fixedly connected between the connecting block 8 and the first auxiliary block 10. The sponge block 7 is set against the inner wall of the receiving groove 14. When the extrusion block 91 moves within the receiving groove 14, the sponge block 7 can play a role in buffering and shock absorption, and at the same time, it can fill any gaps that may exist within the receiving groove 14, preventing dust, impurities, etc. from entering the receiving groove 14 and affecting the movement of the extrusion block 91.
[0033] In this embodiment of the utility model, such as Figure 1 As shown, a second anti-slip pad 4 and a first anti-slip pad 3 are fixedly connected to the nut column body 1 and the corner plate 2, respectively. Multiple anti-slip balls 6 are fixedly connected to the second anti-slip pad 4. Specifically, when the nut column body 1 is installed on the corresponding equipment or structure, the first anti-slip pad 3 can increase the friction between the nut column body 1 and the equipment or structure, while the second anti-slip pad 4 and the anti-slip balls 6 can increase the friction between the nut column body 1 and the mounting surface of the threaded rod, thereby preventing the nut column itself from sliding relative to the ground when subjected to force, and improving the anti-slip effect.
[0034] Working principle: When the threaded rod is screwed into the nut column body 1, the locking block 96 does not obstruct the entry of the threaded rod. The threaded rod is locked as it penetrates deeper into the nut column body 1. The tail end of the threaded rod contacts the compression block 91. As the threaded rod continues to penetrate deeper into the nut column body 1, the tail end of the threaded rod drives the compression block 91 to compress the elastic block 92, causing the elastic block 92 to deform under force. Simultaneously, during the compression process of the elastic block 92, the air inside its internal cavity 93 is discharged to multiple locking blocks 96 through the connecting channel 94 and the air supply pipe, causing the locking blocks 96 to deform towards the threaded rod and embed into the threaded rod. Within the groove, the threaded rod is locked in place. At this point, the threaded rod and the nut column body 1 are installed. The overall structure and operation steps are simple, providing an innovative anti-loosening structure. Utilizing the elastic deformation characteristics of the elastic block 92 and the locking block 96, the threaded rod is effectively limited, improving the anti-loosening performance of the nut column. At the same time, it improves the efficiency of disassembling and assembling the nut column body 1 and the threaded rod, enhancing the convenience of the device. Furthermore, the annular design of the elastic block 92 and the locking block 96 makes the clamping and locking effect on the threaded rod more uniform, providing a stable anti-loosening effect under different working environments, such as vibration, impact, and temperature changes.
