None.

Among the prior art as described above, Patent Document 1 relates to a spring nut for assembling a profile, and Patent Document 2 relates to an installation tool for installing a commonly used spring nut, rather than a channel connection or a technology related to a spring nut. The contents, and Patent Document 3 is to further form a fixing protrusion on the top of the release preventing plate constituting the spring nut so that the fluidity can be excluded, and mainly relates to a technology to be used as a subsidiary material for construction.

Although the above-described spring nut is generally used for construction, it is true that it plays a role of firmly fixing a bracket for connecting various parts or devices to the ceiling of a ship.

A configuration of the channel connection spring nut 1 to which the prior art is applied is as follows.

The bottom is opened with bent portions 2 bent inward on both sides of the lower side, and the upper surface 3 is provided with a channel 5 formed with a plurality of holes or long holes 4, and the bent portion of the channel 5 In (2), a generally rectangular nut body 6 is located, and in the center of the nut body 6, a bolt hole 8 for firmly fixing a bracket or a connecting part with a fixing means 7 such as a bolt is provided. To form.

A spring 9 is interposed on the upper surface of the nut body 6 so as to maintain a state in close contact with the bent portion 2 before fixing the nut body 6 with the fixing means 7, and the nut body 6 A bent portion groove 10 is formed on both sides of the bottom surface of the bent portion 2 so that it can be prevented from flowing when coupled to the fixing means 7 and the nut body 6.

A spring groove 11 is formed around the bolt hole 8 on the upper surface of the nut body 6 so that the spring 9 can be inserted.

In the spring nut of the prior art as described above, the spring is positioned between the nut body and the upper surface of the channel to always push the nut body in the direction of the bent portion, and the diameter of the spring is equal to or smaller than the long hole formed on the upper surface of the channel. When it is made in a shape and is in the long hole position, the nut body cannot be stably maintained.

Particularly, productivity is lowered due to the complicated production process that requires the spring groove formed in the nut body to go through a separate processing process, and the operation of inserting the spring into the spring groove is not easily performed, so a lot of time and manpower are required for assembly. As a result, there is a disadvantage in that competitiveness is weakened due to the increase in production cost.

After assembling by inserting the spring into the spring groove formed in the nut body, plating is performed to prevent corrosion.If the plating solution is not smoothly introduced into the spring groove and is mounted on a ship operating at sea, corrosion due to the penetration of salt It is not free from the cause that the durability is weakened.

In addition, since there is only one nut body, it is possible to connect brackets or connecting parts only in the direction of the open position of the channel, making it difficult to connect in multiple directions, and if the bracket or connecting part is large, it is structurally weak because the fixed position is only one. As time elapses, the connection status is canceled and there is a high risk of a safety accident.

Accordingly, in the present invention, as invented to solve the above problems, flow prevention grooves 103 that are combined with the bent portion 102 formed on the bottom surface of the channel 101 to prevent flow are formed on both sides of the bottom surface. And, a nut body 105 formed with a bolt hole 109 to fasten the bracket 107 to be connected to the center with a fixing bolt 108;

The nut body 105 is separated from the channel 101 by maintaining the nut body 105 in close contact with the bent portion 102 by being interposed between the upper bottom surface of the channel 101 at the top of the nut body 105 Or a spring 106 that prevents falling off;

Including a spring retainer 110 integrally formed with the nut body 105 to stably maintain the spring 106 around the upper bolt hole 109 of the nut body 105;

Ease of spring bonding and avoiding the possibility of dropping after bonding, the plating is improved through smooth flow of the plating solution, so there is no risk of corrosion even for long-term use, and the bracket is fixed only at the lower side of the channel depending on the type of parts or devices to be installed It is possible to achieve the purpose of securing structural stability by fixing it at the lower and upper sides.

The present invention stably maintains the coupling between the nut body and the spring so that the bracket can be smoothly fastened by excluding the fear of being separated or removed from each other, as well as providing ease of manufacture of the spring nut to reduce production cost and increase productivity. It has an effect that can be improved.

The present invention not only prevents the spring from being separated through the long hole formed on the upper surface of the channel, but also enables multi-directional connection by arranging the nut body on the upper and lower sides to mount brackets, etc. on both the upper and lower surfaces of the channel. It is an invention that has various effects such as being able to stably maintain the connected bracket or parts by maintaining structural rigidity.

The channel connection spring nut 100 to which the technology of the present invention is applied, the bent portion 102 formed on the bottom of the channel 101, the direction of the channel can be changed to the bottom, the top or the side by changing the direction of the channel. ) Is provided with a generally rectangular nut body 105 formed on both sides of the bottom of the flow preventing grooves 103 to prevent flow.

The nut body 105 is separated from the channel 101 by maintaining the nut body 105 in close contact with the bent portion 102 by being interposed between the upper bottom of the channel 101 at the top of the nut body 105 Or it is composed of a spring 106 that prevents falling off.

In the center of the nut body 105, a bolt hole 109 for fastening a component to be connected or a bracket 107 (hereinafter referred to as a bracket) with a fixing bolt 108 is formed through.

A spring retainer 110 for stably holding the spring 106 is further integrally formed around the upper bolt hole 109 of the nut body 105, and the spring 106 is the upper surface of the channel 101 In order to prevent separation through the fastening holes 111 formed in a plurality of circular or long holes or falling into the fastening holes 111, the upper diameter (D) is formed larger than the diameter of the lower part (D1). Let's do it.

The spring retainer 110 includes a retaining tube 112 integrally protruding upward from the nut body 105, and a spring 106 coupled by bending integrally laterally from the retaining tube 112 It consists of a departure preventing protrusion 113 to prevent separation.

The nut body 105 at the position of the holding pipe 112 has a width (D2) wider than the lower diameter (D1, outer diameter) of the spring 106 and a height (H) higher than the wire diameter of the spring 106 The seating groove 114 is integrally formed.

Forming the spring seating groove 114 wide and high not only increases the seating property of the spring 106, but also when the plating is performed in a state in which the spring 106 is coupled (assembled), the plating solution is not only used for the spring 106 The purpose is to evenly flow into the entire spring mounting groove 114 to improve the plating power so that the concern of corrosion that may occur in the future can be eliminated.

One side of the spring mounting groove 114 is formed integrally with a locking protrusion groove 116 capable of receiving the locking protrusion 115 of which the lower end of the spring 106 is bent in a direction at right angles to the diameter of the spring 106 It prevents the deviation of the product once more so that the deviation phenomenon can be fundamentally excluded.

When forming the nut body 105 by punching the nut body 105 with a press, the holding pipe 112, the separation prevention protrusion 113, the spring mounting groove 114 and the locking protrusion groove 116 constituting the spring holder 110 It would be natural to design the mold so that it can be formed integrally on the bed so as to eliminate the need for separate post-processing, so that the production cost can be greatly reduced as well as the ease of production.

The separation prevention protrusion 113 maintains a stable coupling state and provides ease of separation prevention rather than forming only on one side of the holding tube 112 so that the spring 106 can be combined and disassembled while rotating in a spiral shape. It would be desirable to form two symmetrically to each other.

In another example of the present invention, the nut body 105 having the spring retainer 110 positioned on the upper side has the lower side connected to the bent portion 102 formed on the bottom of the channel 101, and the spring retainer 110 The nut body 105 so as to be located at the lower side has a pair to be connected to the upper and lower surface of the channel 101, and the spring 106 is interposed on the spring holder 110 for each of the channels 101. The bracket 107 may be fixed with the fixing bolts 108 through the lower and upper directions to ensure structural stability.

In the case of using a pair of nut bodies 105 as described above, the spring 106 may have the same upper and lower diameters as illustrated in the drawing, and the upper and lower circle diameters and the central circle diameters are different. It will be natural that it can be implemented in various forms, such as using a spring 106 of the form.

Looking at the state of use of the channel connection spring nut 100 to which the technology of the present invention is applied as described above is as follows.

First, in the case of using a single type spring nut 100, the spring 106 is coupled to the holding tube 112 of the spring holder 110 formed in the nut body 105 and then positioned in the channel 101. When the upper part diameter (D) of the spring 106 is formed larger than the lower part diameter (D1), the upper part diameter (D) is connected to the upper bottom surface of the channel 101, and the nut body 105 is elastically formed. To be in close contact with the bent portion 102 of the channel 101.

In other words, the bent portion 102 is coupled to the flow prevention grooves 103 formed on both sides of the bottom of the nut body 105 to maintain a stable state of the nut body 105 and prevent movement even in the process of intermittent with the fixing bolt 108. Can be minimized.

When the spring nut 100 is positioned in the channel 101 as described above, the bracket 107 is firmly intercepted with the fixing bolt 108 through the bolt hole 109 formed in the nut body 105 to enable fastening. It becomes possible.

In the case of the twin-type spring nut 100, after the nut body 105 is positioned facing the spring retainer 110, the spring 106 is coupled to the retaining pipe 112 constituting the spring retainer 110. After pressing the upper and lower nut bodies 105 and inserting them into the channel 101, the upper nut body 105 is in close contact with the upper and lower surfaces of the channel 101 by the elasticity of the spring 106, and The nut body 105 of the channel 101 is maintained in contact with the bent portion 102.

In this state, since the bracket 107 can be fixed through both the nut body 105 at the lower position and the nut body 105 at the upper position, it is not only structurally stable, but also the durability can be increased by increasing the fixing force. .

The spring nut 100 to which the technology of the present invention as described above is applied is further integrally formed with the spring retainer 110 on the nut body 105 to facilitate the coupling of the spring 106 while being combined with the spring 106 ) Can be easily separated or separated, and since the spring seating groove 114 formed at the position where the spring is placed is formed wide, the plating solution flows smoothly during the plating operation after the spring 106 is coupled, resulting in poor plating. Since it can be excluded, it is possible to solve the problem due to corrosion even when used for a long time.

In particular, the diameter of the fastening hole 111 formed on the upper surface of the channel 101 by forming the upper diameter (D) of the spring 106 applied to the silgle type spring nut 100 larger than the lower diameter (D1) Since it is formed larger, it is possible to prevent the spring 106 from being separated through the fastening hole 111 and eliminate the problem of stably pushing the nut body 105 due to the spring 106 being inserted into the fastening hole 111. There will be.

In addition, when the spring 106 is coupled to the spring holder 110, it is coupled and separated by rotating it in a spiral, and riding the separation prevention protrusion 113 formed to protrude outward from the holding pipe 112 ,Reverse rotation allows one end of the spring 106 to be helically coupled, and at the end of the spring 106, a locking protrusion 115 bent outwardly from the axis center is formed to be integrated into the spring seating groove 114 By being positioned in the locking protrusion groove 116 formed as, it is always possible to engage in the correct position, so that a certain elasticity can be maintained.

While the nut body 105 of the present invention is formed by a press, the holding pipe 112, the separation prevention protrusion 113, the spring mounting groove 114, and the locking protrusion groove 116 are integrally formed at a time, thus providing ease of manufacture. While excluding post-processing, it has the advantage of being able to greatly reduce production and assembly ease and production cost, and enables production automation.

The present invention as described above improves the plating property through smooth flow of the plating solution while excluding the fear of spring bonding and the possibility of falling off after bonding, and there is no fear of corrosion even for long-term use, It is an invention having various advantages, such as securing structural stability by fixing only at the lower side of the channel or by fixing at the lower and upper sides.
