Description

A push button capable of stably maintaining a locking posture and a connection structure using the same {push-button assembly and channel structures using the same}

The present invention relates to a push button of a structural member, and more particularly, to a push button that interconnects a channel and a channel or simply fastens a structural member such as a bracket to the channel.

It is usually bolted or welded to join two structural members or components. Welding has excellent bonding, but bolting is preferred because of difficulties in field work. Bolts are usually used together with nuts for strong bonding, and are being developed in various ways for the convenience of installation or assembly, referred to as quick fasteners or push buttons. The push button is fastened by a push method with a spring interposed between the bolt and the nut.

The prior art as the structural member is disclosed in Korean Patent Application Laid-Open No. 2003-0011298 (a frame material with a traveling rail attached to the conveyor system and a traveling frame device using the frame material), Republic of Korea Patent Registration No. 10- 1654871 (Seed-shaped manufacturing apparatus having a panel fastening hole), Korean Patent Laid-Open Publication No. 10-2015-0129842 (Channel framing having additional functional aspects and a fitting part therefor) is disclosed. In addition, the prior art of the push button is disclosed in Korean Patent Laid-Open Publication No. 10-2018-0079294 (connection assembly for rail mounting). Referring to Republic of Korea Patent Publication No. 10-2018-0079294 (connection assembly for rail mounting), the holder is interposed between the bolt and the lock nut, and the rotation of the holder is restricted in the non-circular hole of the connector so as to be in the intended position. For this purpose, an appropriate special shape is presented by paying attention to the shape of the non-circular hole of the holder and connector. That is, an anti-rotation element or a counter bearing is arranged in a connector hole in which each surface and an arc surface are combined, or in a holder. Since the non-circular shape of the connector and the holder are matched, work in the order of the holder/lock nut after the connector/holder is combined. They are then placed in the slots of the rails and bolted to connect the structural members to each other.

In general, various types of pushbuttons and brackets (referred to as connectors in the prior art) are used for coupling of structural members. When the pushbutton and the bracket are dependent on each other, their use is extremely limited. Pushbuttons can be used with other types of brackets, and the brackets must also be compatible with other types of pushbuttons. However, in the case of such a prior art, since the non-circular hole of the bracket and the holder must be matched with each other, their use is limited in a dependent relationship. And since the lock nut cannot pass through the non-circular hole, it must be assembled on site rather than factory assembly, which is inconvenient and expensive. On-site assembly of pushbuttons is complicated and time-consuming, which is disadvantageous for fast fastening. In addition, the push button does not solve the slip problem only by pressing the bracket. Furthermore, it should be possible to inspect the appearance of the fastening or work, but after work, the push button is wrapped around the bracket and rail, so it is difficult to check the fastening state. Even if a separate inspection equipment is used, it is difficult to realistically check high places. In case of poor fastening of the structure, the reliability of the work is reduced and the structure collapse is concerned.

Republic of Korea Patent Publication No. 10-2018-0079294

The present invention has been devised to solve the above problems, and it is an object of the present invention to provide a push button and a connecting structure thereof that can be assembled at a factory and easily and quickly connected to a structural member in the field.

In order to achieve the above object, in a state in which the first non-circular hole provided in the bracket and the second non-circular hole provided in the channel communicate with each other, the first non-circular hole and the second non-circular hole are bolted to each other. It is used to couple the bracket and the channel between the bolt head and the nut by passing one of the head and the nut and the threaded bolt body: to face the first member of any one of the bolt head and the nut a cap plate disposed and provided with a bolt insertion hole so that the bolt body can pass therethrough; a holder body having a non-circular shape having a length longer than the width in order to stop the rotation by being caught in the channel of the second non-circular hole when the bracket and the channel are combined so that the bolt body can pass therethrough; and a locking element accommodating part disposed downward from the holder body and accommodating the second member of the other one of the bolt head and the nut; a push button having a; and a connection structure using the same.

As described above, in the push button according to the present invention, the locking position can be determined more conveniently without separate manipulation according to the non-circular shape of the holder, and since the holder head takes a posture through the non-circular hole, the shape of the non-circular hole of the bracket It is not limited, so the selection of structural members is widened, and according to the configuration in which the holder head passes through the bracket and is caught on the channel to prevent rotation, it can be positioned closer to the locking element accommodating part to maintain the locking posture more stably.

First, terms for describing the push button according to the present invention are defined. Structural members in the field of the present invention may be simply rod-shaped, but are used by bending into various shapes or shapes for C-shaped steel or high rigidity. These structural members are referred to as “C-beams” or “channels” or “rails” or other various names. Hereinafter, the structural member is referred to as "channel". In addition, a channel and a channel may be directly connected, a connector or a bracket may be used as a medium, or a device, equipment, or electrical equipment may be directly installed or placed on a channel, or connectors or brackets may be overlapped and used. Hereinafter, for convenience of explanation and understanding, one of the two members fastened with a push button is called a “channel” and the other member is called a “bracket”. In addition, the shape of the through hole of the bracket through which the push button passes may be formed in various ways in relation to the push button, more specifically, the holder and the bolt or nut, and it is difficult to determine one of them. Accordingly, at least the minimum diameter and the maximum diameter of the through hole of the bracket are different from each other, and a "non-circular hole" will be described as an example thereof. And, for convenience of description, as terms referring to the direction, “upward” and “downward” are used. These "upward" and "downward" are referred to as "upward" as the upward direction toward the bracket with respect to the bolt at the time of fastening, and the downward direction toward the channel in the opposite direction is referred to as "downward". Also, we use "extrovert" and "introvert". "Inward" refers to a direction toward an axis or center, and vice versa, refers to a direction away from the center or axis as "outward". And we use "top" and "bottom" or "bottom" to describe a single part. "Upper surface" refers to a surface located in the direction toward the bracket with respect to the bolt, and "bottom" and "lower surface" refer to a surface located in the opposite direction. We also use "inner face" and "outer face" in the absence of spatial divisions. The "inner surface" refers to a surface in contact with the inner space, and the opposite surface to the surface in contact with the outer space is referred to as an "outer surface".

A push button and a connection structure using the same will be described as an embodiment according to the present invention.

Referring to FIG. 1 , as a preferred embodiment according to the present invention, the connection structure 1 includes a channel 10 , a bracket 20 , and a push button 30 .

The channel 10 is formed in a hollow profile as a whole, and, as an example, has two curtain walls 11 bent downward from the upper side by multi-stage bending molding. The two curtain walls 11 are spaced apart from each other facing each other, and a slot H1 opened therebetween is provided. The push button 30 is inserted into the slot H1 and fixed, and it is preferable that the concave and convex teeth 11a are provided on the lower side thereof for strong binding. Here, reference numeral “B” denotes the width of the slot H1.

The bracket 20 is a plate-shaped member, and a non-circular hole H2 is provided as a through hole through which the push button 30 can pass. The illustrated example shows a bracket 20 having a 90° bent shape as an example for connecting the intersecting channels. Here, the non-circular hole H2 is related to the shape of the push button 30 , which is an open hole that is accommodated in one direction but is not accommodated in the other direction, and has a minimum diameter and a maximum diameter as another example, an oval or an oval shape. Other polygons fall into this category.

On the other hand, the slot H1 is a long and narrow space, and communicates with the non-circular hole H2 of the bracket 20 when the channel 10 and the bracket 20 are coupled, and the bracket 20 ) may be a non-circular hole of another shape corresponding to the non-circular hole H1. Separately, it can be said that the first non-circular hole H2 is formed in the bracket 20 and the second non-circular hole is formed in the channel 10 . However, for convenience of explanation and understanding, the first non-circular hole H2 formed in the bracket is simply referred to as a non-circular hole, and the second non-circular hole is referred to as a slot H1.

2 is a front perspective view showing a push button from the upper side as an embodiment according to the present invention, and FIG. 3 is a front exploded perspective view showing the push button from the upper side by separating the push button as a temporary embodiment according to the present invention, FIG. 4 is As an embodiment according to the present invention, it is an exploded perspective view of the bottom surface shown from the lower side by separating the push button, and Figure 5 is a cross-sectional view showing the push button along the longitudinal direction of the bolt head as an embodiment according to the present invention.

1 to 5 , the push button 30 includes a bolt 110 , a holder 120 , a cap plate 130 , a spring 140 , and a nut 150 .

The bolt 110 includes a bolt head 113 and a bolt body 115 .

The bolt body 115 is provided with a threaded portion 115a with a thread, and is integrally formed with the bolt head 113 . The bolt body 115 is greater than the sum of the height of the curtain wall 11 of the channel 10, the thickness of the bracket 20, and the height of the nut. In this case, the bolt body may be exposed when the channel 10 and the bracket 20 are coupled, which will be described later.

The bolt head 113 has an overall rectangular parallelepiped shape, and lock shoes 113a and 113b are provided on both sides along the longitudinal direction. The lock shoes 113a and 113b are provided with teeth 113t on the upper side thereof, and the teeth 113t have a shape corresponding to the teeth 11a of the curtain wall 11, and thus mesh when aligned with each other. can be

The holder 120 includes a holder body 121 and a locking element receiving portion 122 .

The holder body 121 is provided with a bolt hole (121a) in its central portion so that the bolt body 115 can pass therethrough. The holder body 121 has a shape in which the outer circumferential surface gradually protrudes to both sides when viewed in a plan view, and has a non-circular shape with a length longer than the width as a whole. The width and length of the holder body 121 are smaller than the width and length of the slot H1 of the channel 10 and the non-circular hole H2 of the bracket 10 . However, the length of the holder body 121 is somewhat longer than the width of the slot H1. Accordingly, the holder body 121 can pass through the slot H1 and the non-circular hole H2 in the longitudinal direction, and when rotated after being accommodated in the slot H1, it is caught on the curtain wall 11 and can stop rotating. have.

The holder body 121 may be variously formed in a non-circular shape of each surface or curved surface, but it is preferable to have a rotation limiting surface formed in a curved surface so as to be smoothly caught on the channel 10 and rotate away. As an example of the rotation limiting surface of the curved surface formed on the holder body 121, as shown, arc surfaces of different radii of curvature are in contact with each other and protrude outward, or may be wavy as a whole. In this case, the holder body 121 ) can operate more smoothly when caught or released when the curtain wall 11 is rotated.

The holder body 121 is provided with a locking pin (121b). Two of the locking pins 121b are arranged in parallel along the longitudinal direction of the holder body 121 . The locking pin 121b is to be hooked on the locking groove portion 132b provided in the cap plate, and in the case of the illustrated example, it is formed on the holder body 121, but it is not necessary to be limited thereto. relationship, which will be described later.

The holder body 121 is provided with a locking element receiving portion 122 . The locking element accommodating part 122 has a shape in which two bars facing each other in the width direction of the holder body 121 protrude downward, and the length of the protrusion is greater than the thickness of the bolt head 113, so the locking element therebetween. A receiving groove (122a) is provided. Accordingly, when the bolt body 115 is inserted into the bolt hole 121a of the holder body 121, the bolt head 113 is accommodated in the locking element accommodating groove 122a and disposed in the longitudinal direction of the holder body 121. do.

A locking protrusion 112b is provided at the lower end of the locking element accommodating part 122 . The locking protrusion 112b is disposed to face each other as a pair of two protruding inwardly from the locking element accommodating groove 122a. Accordingly, when the bolt head 113 is accommodated in the locking element accommodating part 122, the bolt head 113 is caught and does not fall down. Here, although the holder body 121 and the locking element accommodating part 122 have been described and illustrated in more detail, the shape can be variously changed, for example, an assembly structure as well as an integral shape or other various modifications according to convenience. However, it is preferable that the bolt head 113 can be supported in a balanced manner when arranged facing each other as a pair of two.

The cap plate 130 includes a cap body 131 , locking legs 133 and 134 , pressing legs 135 and 136 , and a bolt guide 132 .

The cap body 131 has a circular shape as a whole, and a bolt insertion hole 131a is provided in the central portion thereof.

The locking legs 133 and 134 are inclined downward from the cap body 131 to protrude and extend, and two locking legs 133 and 134 are provided on both sides around the bolt insertion hole 131a. The locking legs 133 and 134 are to be received and fitted in the non-circular hole H2 of the bracket 20, which will be described later.

The pressure legs 135 and 136 have a shape protruding from the cap body 131 in the horizontal direction, are disposed orthogonally to the lock legs 133 and 134, and are formed on both sides with the bolt insertion hole 131a as the center. dog is provided The pressure legs 135 and 136 are seated on the upper surface of the bracket 20 and coupled thereto, which will be described later.

On the other hand, as will be described later, the pressing legs 135 and 136 increase the contact resistance with the bracket 20 , and the locking legs 133 and 134 are fitted to the non-circular hole H2 of the bracket 20 and coupled thereto. In order to do this, the size of the pressure legs 135 and 136 is increased to increase the contact resistance, and the size of the lock legs 133 and 134 is slightly larger than the size of the non-circular hole H2 of the bracket 20. desirable. Although the number of the locking legs 133 and 134 and the pressing legs 135 and 136 may be varied, it is preferable to make a pair of two as shown in the figure so that they are stably bound in a balanced manner. The locking legs 133 and 134 and the pressing legs 135 and 136 are disposed to cross each other, and it is preferable to arrange them in a direction orthogonal to each other for stable and strong bonding. In addition, the locking legs 133 and 134 are coupled to the non-circular hole H2 according to the tightening of the nut 150 , so that they are strong in lateral force, but have limited vertical force. However, since the pressing legs 135 and 136 come into contact with the bracket 20 without the non-circular hole H2, the pressing performance according to the tightening of the nut 150 is excellent. Accordingly, the pressing legs 135 and 136 are preferably arranged in the same direction as the longitudinal direction of the bolt head 113, and positioned on the same working surface in the projection plane. Accordingly, the lock shoes 113a and 113b and the pressing legs 135 and 136 are disposed to face up and down, so that the channel 10 and the bracket 20 can be firmly fastened according to the tightening of the nut 150 .

The bolt guide 132 protrudes downward through the bolt insertion hole 131a of the cap plate 130 . In the case of the illustrated example, the bolt guide 132 is integral with the cap body 131 and protrudes downward from the cap body 131, so it is difficult to clearly distinguish and explain the boundary, but for convenience of explanation and understanding Let's look at it separately. The bolt guide 132 has a shape fitted into the bolt insertion hole 131a of the cap body 131 and is integrally coupled, and a bolt through hole 132a through which the bolt body 115 can pass is provided. do. When viewed from the perspective that the bolt guide 132 is inserted into the bolt insertion hole 131a of the cap body 1312, the bolt through hole 132a has a shape partially overlapped with the bolt insertion hole 131a and is substantially in communication. .

A spring 140 is accommodated in the bolt guide 132 . The bolt guide 132 may have various shapes and shapes, and as examples thereof, may be a hollow tube having a partial cut or side opening, a stepped shape, or a truncated cone shape. The accommodating space of the bolt guide 132 may have various shapes in which the width of the lower side is narrower than the width of the upper side. When the space in which the spring is accommodated in the bolt guide 132 is cut into a truncated cone shape (the truncated cone shape is generally a conical shape in a plane parallel to the bottom, removing the part with the vertex and the remaining part) Even in the case of the shape of , there is a difference in the shape, but the function is the same. Hereinafter, the three-dimensional shape consisting of the part with the vertices, including both the shape of the cone and the pyramid, is referred to as a truncated cone shape.) , since the cross-section is inclined inwardly, even if the spring 140 is accommodated, it can be naturally caught and fixed, and processing is convenient because there is no need for a separate spring seat. The receiving space that can accommodate the spring in the bolt guide 132 is, when the spring 140 is accommodated and compressed, after the elastic deformation of the spring 140, the nut 150 can contact and press the cap body. provide space.

The bolt guide 132 is provided with a locking groove portion 132b on the lower side thereof. Since the locking groove portion 132b is to operate in correspondence with the locking pin 121b of the holder body 121, its shape and position are also determined by the shape and position of the locking pin 121b. Accordingly, two locking grooves 132b are formed side by side in the longitudinal direction of the holder body 121 like the locking pins 121b. Accordingly, when the locking pin 121b and the locking groove portion 132b are displaced from each other, the holder body 121 and the cap plate 130 may rotate relative to each other, but as the relative rotation proceeds, the locking pin When the (121b) is accommodated in the locking groove (132b), the holder body 121 and the cap plate 130 are prevented from rotating relative to each other so that they can move together.

On the other hand, the locking groove portion 131b and the locking pin 121b are for the relative rotation or behavior of the cap plate 130 and the holder body 121 together. A locking pin 121b is formed on the body 121, and two are arranged to hold it in a balanced and stable manner, and are arranged in the longitudinal direction of the holder body 121 to function as a direction indicator. However, the locking groove portion 131b and the locking pin 121b can be variously changed in shape, structure, or number, and in particular, the arrangement of the locking groove portion 131b and the locking pin 121b may be different from each other. can That is, as another embodiment, the locking groove portion may be disposed on the holder body 121 , and the locking pin may be disposed on the cap plate 130 . Even if the arrangement is different, as described above, the locking pin is accommodated in the locking groove so that the holder body 121 and the cap plate 130 are prevented from rotating relative to each other. As such, the shape, structure, or number or arrangement of the locking groove portion 131b and the locking pin 121b can be freely changed, and since this is obvious in the field of the present invention, a detailed description thereof will be omitted.

The spring 140 is disposed between the cap plate 130 and the nut 150 . As long as the spring 140 can elastically support between the cap plate 130 and the nut 150, various types of known springs may be used. For example, a conical coil spring corresponding to the conical shape of the bolt guide 132 may be used. The illustrated example shows a coil helical spring as an example of the spring 140 . The spring 140, the height of the state without external force, that is, the free field may be greater than the protrusion length of the bolt guide 132, but the length when compressed by the nut 150, that is, the close contact height is the bolt guide It is preferable to make it smaller than the protrusion length of (132). If, in order to increase the elastic force, the height of the close contact of the spring 140 is greater than the protrusion length of the bolt guide 132 , a concave portion may be provided in the cap plate 130 . Accordingly, when the spring 140 is compressed, the pressure legs 135 and 136 can be pressed in close contact with the bracket 20 in a state that is charged and elastically supported by the bolt guide 132 . On the other hand, in the case of the illustrated example, the spring 140 is disposed between the cap plate 130 and the nut 150 , but as a modified embodiment, the arrangement of the spring 140 is changed to form the cap plate 130 and the cap plate 130 . It may be disposed between the holder body 121 . Such a modified embodiment is possible by arranging the spring 140 on the bolt guide 132, or by making a portion protruding upward from the holder body 121 and arranging it therebetween. In this way, it is natural that the arrangement of the spring 140 can be changed in various ways while maintaining its function so that the holder body 121 interacts with the channel 10, but the holder body 121 and the cap body 131 In consideration of the narrow distance between ) is preferably disposed between.

The nut 150 has a female screw formed in the screw hole 150a and is screwed with the bolt body 115 . The nut 150 may have various shapes or structures known in the field of the present invention, but it is preferable that the nut 150 is attached to a wide flange 150b, such as a flanged nut or a collared nut. . The flange 150b has a shape protruding outward to face the cap body 131, and as is known, the bottom surface thereof is preferably formed in a sawtooth shape to increase contact friction. On the other hand, when a flanged nut or a collared nut is used, it has a good effect on friction characteristics and is favorably used. When pressing and tightening, a push function can be given, which makes work easier.

Assembling, mounting and operation of the push button and the connection structure as an embodiment according to the present invention will be described.

First, an assembling process of a push button as an embodiment according to the present invention will be described.

2 to 5 , when assembling the push button 30 as an embodiment according to the present invention, the bolt body 115 is inserted into the bolt hole 121a of the holder 120 first, and the lock element receiving part Position the bolt head 113 at (122). At this time, the bolt head 113 and the holder body 121 are arranged in parallel in the longitudinal direction thereof, and the bolt head 113 is caught by the engaging projection 122b of the locking element accommodating part 122 and does not fall down. Accordingly, even if the push button 30 flows in the assembly step, the bolt head 113 does not come off and assembly is easy.

When the bolt body 115 is inserted into the bolt insertion hole 131a through the bolt guide 132 , the locking pin 121b provided in the shape of two protrusions comes into contact with the lower surface of the bolt guide 132 . At this time, the locking pin (121b) and the locking groove (132b) are in a state in which they are mated to each other.

When the spring 140 is inserted into the bolt body 115 , it is placed on the conical surface of the bolt guide 132 .

When the nut is turned to match the screw portion 115a of the bolt body 115, the nut 150 moves downward on the screw thread of the screw portion 115a of the bolt body 115. The bolt body 115 is not yet exposed to the outside of the nut, and the spring 140 elastically pushes between the bolt guide 132 and the nut 150 . Accordingly, the bolt guide 132 and the holder body 121 are in a state close to each other, and the cap plate 130 and the nut 150 are in a state away from each other.

Next, a process of mounting the connection structure using a push button as an embodiment according to the present invention will be described.

Referring to FIG. 1 , when the connection structure 1 is fastened by mounting the push button 30 on the channel 10 and the bracket 20 , first of the slot H1 of the channel 10 and the bracket 20 The channel 10 and the bracket 20 are arranged so that the non-circular hole H2 overlaps and communicates with each other, and the push button 30 is positioned in the longitudinal direction of the bolt head 113 and fitted.

6 is a perspective view of a connection structure as a preferred embodiment according to the present invention, and shows a state before the channel and the bracket are combined, and FIG. 7 is a cross-sectional view of the connection structure as a preferred embodiment according to the present invention. The state before this coupling is shown along the line AA of FIG. 6, and FIG. 8 is a cross-sectional view of the push button as a preferred embodiment according to the present invention. will be. And Figure 9 is a plan view showing the arrangement of some of the components in the connection structure as a preferred embodiment according to the present invention. Here, even if the locking pin 121b and the locking groove portion 132b are assembled in a state in which they are not engaged with each other, their operations and actions are the same, but for convenience of explanation and understanding, the locking pin 121b and the locking groove portion 132b ) is shown and described as an example of an assembled state in which they are aligned.

6 to 9, when the push button 30 is moved downward and inserted into the non-circular hole H2 and the slot H1, the locking legs 133 and 134 are caught on the bracket 20, and the bolt guide 132. , the holder 120 and the bolt head 113 enter the non-circular hole (H2) and the slot (H1). At this time, the nut 150 and the cap body 131 are spaced apart by a distance t1 therebetween, and the spring 140 is pulling the holder 120 and the bolt head 113 upward. In addition, the bolt head 113, the holder body 121, the locking pin 121b, and the locking groove portion 132b are disposed in the longitudinal direction of the slot H1 and the non-circular hole H2, and the locking legs 133 and 134. ) is disposed in the width direction of the slot H1. Since the locking legs 133 and 134 are inclined, the bracket 20 and the cap body 131 are separated from each other. When the push button 30 is turned in this state, the bolt head 113 cannot be rotated because it is caught on the curtain wall 11 .

7 and 8 , when an external force F is applied by pressing the bolt 110 , the nut 150 and the bolt 110 move downward. At this time, the spring 140 is compressed and accommodated in the bolt guide 132 , and the flange 150b of the nut 150 contacts the cap body 131 . And, since the holder 120 moves downward together with the bolt 110 , the locking pin 121b of the holder 120 and the locking groove 132b of the bolt guide 132 are released. The distance t1 that the nut 150 moves is the distance t2 that the bolt head 113 moves, and the distances t1 and t2 are the height difference between the holder body 121 and the curtain wall 11 ( t3) is greater than Accordingly, the bolt head 113 is positioned below by the clearance distance t4 of the curtain wall 11 . Accordingly, when the push button 30 is turned while the bolt 110 is pressed, the bolt head 113 rotates without being caught on the curtain wall 11 .

10 is a perspective view of a connection structure as a preferred embodiment according to the present invention, showing a state in which the push button is rotated at an angle horizontally.

Referring to FIG. 10 , when the push button 30 is turned while the bolt 110 is pressed, the cap plate 130 rotates in frictional contact with the nut 150 .

11 is a cross-sectional view taken along line BB of FIG. 10 in a state in which the bolt head and the curtain wall are locked as a preferred embodiment according to the present invention, and FIG. 12 is a horizontal push button as a preferred embodiment according to the present invention. It is a plan view showing a state in which the members of the connecting structure are arranged in a state of angular rotation.

11 and 12 , according to the rotation of the push button 30 , the holder body 121 is caught on the curtain wall 11 and does not rotate. At this time, when the pressure of the bolt 110 is released, the bolt guide 132 is placed on the locking pin 121b, and since the bolt head 113 is perpendicular to the curtain wall 11, the bolt head 113 and the curtain wall The teeth of (11) mesh. In this case, the locking pin 121b and the locking groove portion 132b are not yet mated.

Meanwhile, since the bolt head 113 is fixed, the nut 150 can be tightened. When the nut 150 is tightened, the nut 150 moves downward on the thread of the threaded portion 115a of the bolt 110 . As the nut 150 moves, the elastic force of the spring 140 also increases. Accordingly, the bolt guide 132 overcomes the frictional force between the nut 150 and the locking pin 121b and rotates.

13 is a perspective view of a connection structure as a preferred embodiment according to the present invention, showing a state in which a push button is mounted, and FIG. 15 is a perspective view of a connection structure as a preferred embodiment according to the present invention, in which a push button is mounted. The state is shown along the line CC of FIG. 13, and FIG. 14 is a plan view showing a state in which a member of the connection structure is disposed in a state in which the push button is mounted as a preferred embodiment according to the present invention.

As the bolt guide 132 rotates, the locking groove portion 132b and the locking pin 121b meet and engage to stop the rotation. At this time, the holder body 121 is in a state of being fixed by being caught on the curtain wall 11, the bolt head 113 is in a state where it is fixed by meshing with the curtain wall 11, and the locking legs 133 and 134 are non-circular holes. In the direction of (H2), the pressing legs (135, 136) are disposed in a direction perpendicular to the bracket (20).

As the nut 150 is tightened, the locking legs 133 and 134 face the non-circular hole H2 of the bracket 20, so that they are gradually fitted into the non-circular hole H2, and the pressing leg 135 , 136 presses the bracket 20 . Then, the bolt body 115 is exposed to the outside by moving upward on the nut 150 screw thread. When the bolt body 115 is exposed to the outside, the fastening is good, and when it is not exposed, it can be determined that the fastening is defective. In this way, it is possible to check the working state according to the degree of exposure of the bolt body 115 before and after fastening or not.

On the other hand, in the case of the push button 30 according to the present invention, a spring is interposed between the cap plate 130 and the nut 150 , so there is no need to press the cap plate 130 , and only the nut 150 . It is pressed, and accordingly, even if it is pressed with a small force, the push function can be performed smoothly. In general, when tightening the nut 150, a tightening mechanism, such as a socket wrench, is used. In the case of the push button 30 according to the present invention, since the tightening mechanism has a structure that can be caught on the flange 150b of the nut 150, it can be operated with a small force in addition to the weight of the tightening mechanism, and the tightening mechanism By simply turning, the holder body 121, the locking pin 121b, and the locking groove portion 132b sequentially interact to be hooked and fixed, so the operation is very convenient.

16 is a front exploded perspective view of a push button as another embodiment according to the present invention, and FIG. 17 is a bottom exploded perspective view of the push button of FIG. 16 as another embodiment according to the present invention. Here, the same reference numerals as those shown and described above mean the same members having the same function.

16 and 17 , as another embodiment according to the present invention, the push button 300 has no locking pin 121b as described and illustrated in advance of the bolt guide 132 , and in front of the holder body 321 . It is the same as the push button 30 as an embodiment shown and described above, except that there is no locking groove portion 132b as described and shown.

When assembling the push button 300, the spring 140 is positioned between the nut 150 and the bolt guide 332 of the cap plate 330. At this time, according to the elastic action of the spring 140, the bolt guide ( There are some differences in that the lower surface of the 332 is in contact with the upper surface of the holder body 321 .

When rotating by pressing the push button 300, the holder body 321 of the holder 320 is caught on the curtain wall (11: see FIGS. 12 and 15) and stops the rotation of the embodiment described and shown above. It is the same as the push button 30 (refer to FIGS. 3 and 4).

When releasing the pressure of the push button 300 and tightening the nut 150, the locking pin 121b of the push button 30 of the embodiment shown and described above (refer to FIGS. 3 and 4) and the locking groove portion 132b 3 and 4), but the locking legs 133 and 134 are caught by the non-circular hole (H2: see FIG. 15) of the bracket 20 and fixed, so that the locking posture can be obtained. However, when the lower surface of the bolt guide 332 and the holder body 321 are in full contact with the surface friction, the cap plate 330 may not be able to rotate smoothly when the nut 150 is tightened. In this case, the operator may manually move the locking legs 133 and 134 to the non-circular hole H2 (refer to FIGS. 12 and 15 ), but it is disadvantageous because a one-step work process is added. Accordingly, it is preferable to change the shape of the bolt guide 332 to reduce the contact resistance of the lower surface or the contact surface of the holder body 321 so as to make a line contact or a partial contact.

In general, a push button combines a structural member simply and quickly with a bolt, a nut, and a spring. In the case of such a push button, two structural members 10 and 20 are disposed between the bolt head and the nut, and are coupled by a compressive force according to screw coupling. At this time, any one of the bolt head or the nut should pass through the non-circular holes (H1, H2) of the structural member as a locking element and be positioned in the locked position, and the non-circular holes (H1, H2) of the structural member (10, 20) Since it has to pass through, it has a narrow width and a long shape corresponding to the shape of the non-circular holes (H1, H2) of the structural members (10, 20). In the pushbuttons 30 and 300 as preferred embodiments according to the present invention, the bolt head 113 has been described in more detail and in detail with reference to the drawings as an example of the locking element, but it should be understood that this is merely exemplary. In the case of the illustrated example, the bolt head 113 and the bolt body 115 are integrated in a "T bolt" shape, and the overall shape is "T". However, the bolt head 113 shows an example functioning as a locking element, and may be clamped by screwing or various known methods without being integrated with the bolt body 115 . On the other hand, as seen in the prior art literature, a hexagonal or flange bolt (flang bolt) may be used, in this case, as shown in the prior art literature, a nut may be used as a locking element. At this time, it can be seen that the bolt head 113 of the illustrated example is changed to a nut. The difference from the pushbuttons 30 and 300 as the embodiments according to the present invention described and shown above is that the locking element 150 is a bolt head 113, whereas, as a modified embodiment thereof, when a nut is applied as a locking element, the They are identical to each other except that the arrangement is different and the nut functions as a locking element. However, in the effect, when the bolt head 113 is applied as a locking element as an embodiment according to the present invention, since the bolt body 115 can be exposed to the outside through the nut 150 , an operator or inspector It is advantageous because it is possible to easily check the fastening state of the pushbuttons 30 and 300 by visually observing the appearance.

As described above, the push button and the connection structure using the same according to the present invention have been described and illustrated in more detail, but this should be understood for convenience of explanation and understanding of the push button and the connection structure according to the present invention, and the above-described shape or It should not be construed as limited to the shape, reference signs, accessories, or parts thereof, and should not be construed as limited by using other documents against the description of the present invention, and the scope of rights of the push button and the connection structure according to the present invention is the attached patent.
