Description

Mounting parts and guide rail installation structure

technical field

Various embodiments of the present invention relate to the field of device installation, and more specifically relate to a mounting part and a guide rail installation structure including the mounting part.

Background technique

Programmable logic controllers (PLCs) are usually mounted on rails in the control cabinet through a backplane. At present, the existing method of installing the PLC on the guide rail of the control cabinet is to install the elastic element on the back plate, and apply a large force to the guide rail installed in the groove of the back plate through the elastic element to provide the guide rail in the direction of force application. At the same time of fixing, the huge pressure of the elastic element provides sufficient frictional force between the contact surface of the elastic element and the guide rail, thereby fixing the backboard in the longitudinal direction of the guide rail. This existing installation method can provide a reliable and stable fixed connection between the backplane and the guide rail.

However, due to the large enough pressure of the elastic element required to generate friction, the above-mentioned existing installation method requires the user to use a large thrust to install the guide rail into the groove of the backplane by overcoming the resistance of the elastic element during installation. This is very inconvenient for the user and results in a very poor installation experience for the user.

Detailed ways

The principle and spirit of the present invention will be described below with reference to several exemplary embodiments shown in the accompanying drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and implement the present invention, but not to limit the scope of the present invention in any way.

FIG. 1 is a perspective view of a mount according to an exemplary embodiment of the present invention, and FIG. 2 is a partially enlarged view of area A in FIG. 1 .

As shown in FIG. 1 , the installation part 10 in FIG. 1 is fixed on the rear side of the programmable controller 1 in the form of a backboard. For example, the mounting part can be fixed to the rear side of the programmable controller 1 by various known connection methods such as screws and buckles. It should be understood that the mounting part 10 can also be integrally formed on the rear side of the programmable controller 1 .

The mounting part 10 can be used to cooperate with, for example, a guide rail 20 located in a control cabinet, so as to install the programmable controller 1 on the guide rail 20 .

According to an exemplary embodiment of the present invention, the mounting part 10 may include a body 11, for example, a substantially flat plate shape. The body 11 has a mounting groove, which has an upper mounting surface 12 , a lower mounting surface 13 opposite to the upper mounting surface, and a side mounting surface 14 between the upper mounting surface 12 and the lower mounting surface 13 . According to an exemplary embodiment, the upper mounting surface 12 and the lower mounting surface 13 are parallel to each other, and the side mounting surface 14 is perpendicular to the upper mounting surface 12 and the lower mounting surface 13 . The installation groove is used for cooperating installation with the fitting in the form of the guide rail 20 . According to an exemplary embodiment of the present utility model, the distance between the upper mounting surface 12 and the lower mounting surface 16 (ie, the width of the groove) matches the width of the guide rail 20, so that the guide rail 20 can just be installed in the groove, and has Clearance suitable for installation.

As shown in Figures 1 and 2, according to an alternative embodiment, a hole or slot 15 is formed on the body 11, and the elastic element 16 can be installed in the hole or slot 15, and can be lifted from the upper mounting surface 12 in a natural state. stick out of the opening. The elastic element 16 can be compressed in a direction perpendicular to the upper mounting surface 12 . The elastic element 16 can be, for example, a helical spring, but it can also be a leaf spring and other structures capable of providing restoring force, which is not limited by the present invention.

As shown in FIGS. 1 and 2 , a friction member 17 is also installed on the body 11 . The friction member 17 protrudes from the side mounting surface 14 . In one embodiment, the friction member 17 is located on a side of the side mounting surface 14 close to the upper mounting surface 12 and adjacent to the upper mounting surface 12 . The friction member 14 is compressible in a direction perpendicular to the side mounting surface 14 .

It should be understood that, in another embodiment, the friction member 11 may also be arranged on a side of the side installation surface 14 close to the lower installation surface 13 . In a further embodiment, the friction member 11 may be arranged at positions close to the upper mounting surface 12 and close to the lower mounting surface 13 at the same time.

For example, the friction member 11 is an elastic or flexible material that is easily compressed and has a relatively high coefficient of friction. Optionally, the friction member 11 is rubber or plastic. In order for the friction member to provide sufficient frictional force and to facilitate installation without excessive deformation pressure, when the installation member is installed correctly, the friction member 11 should have an appropriate amount of deformation. The amount of deformation is preferably 0.3-0.5 mm.

According to an exemplary embodiment of the present utility model, raised stoppers 18 may be respectively provided on the upper installation surface 12 and/or the lower installation surface 13 . The block 18 is used to prevent the guide rail 20 from disengaging from the installation groove.

According to an exemplary embodiment of the present invention, ribs 19 are provided on the side mounting surface 14 of the mounting groove, adjacent to the lower mounting surface 13 . The rib 19 is used to cooperate with the stopper 18 on the lower mounting surface 13 to clamp the lower side edge 21 of the guide rail 20 . For example, the ribs 19 may be symmetrically distributed on both sides of the raised stop 18 on each lower mounting surface so as to securely clamp the lower edge 21 of the guide rail 20 . Optionally, a rib in the form of a continuous convex surface along the extending direction of the installation groove may be provided on the side installation surface 14 adjacent to the lower installation surface 13 .

According to an exemplary embodiment of the present invention, the mounting member 10 can be provided with different numbers of elastic elements 16 and friction members 17 according to the length of the mounting groove, so as to ensure reliable fixing in the extending direction. For example, as shown in FIG. 1 , the mounting part has two elastic elements and two friction parts.

Those skilled in the art should understand that the elastic elements 16 and the friction members 17 can be arranged and distributed in any form in the extending direction of the mounting groove, as long as sufficient vertical elastic element force and horizontal force can be provided for the mounting member 10 in the entire extending direction friction.

FIG. 3 is a perspective view of the mounting member in FIG. 1 being mounted to a guide rail according to an exemplary embodiment of the present invention.

As shown in Figure 3, when the mounting part 10 is installed on the guide rail 20, the gravity of the programmable controller 1 fixed together with the mounting part 10 makes the upper surface of the guide rail 20 press the elastic element 16 so that it is directed towards the upper mounting surface 12 shrinkage. The restoring force of the elastic element 17 supports the entire installation part and the programmable controller 1 on the upper surface 22 of the guide rail, and makes the compressed elastic element 17 protrude from the upper installation surface 12 to a length substantially equal to that between the upper and lower installation surfaces. The difference between the distance and the rail width is the gap width. In this way, the compressed elastic element 17 also makes the lower mounting surface 13 of the mounting part abut against the lower surface 23 of the guide rail, thereby preventing the mounting part 10 from moving relative to the guide rail in a direction perpendicular to the upper and lower mounting surfaces 12, 13. sports.

In an exemplary embodiment of the present invention, the elastic element 16 needs to have sufficient strength to support the weight of the entire mounting part and the programmable controller, and to press the lower mounting surface against the lower surface of the guide rail. However, the strength of the elastic member 16 does not need to be large enough to provide a sufficiently large positive pressure to the upper surface of the rail 20 to create a force between the elastic member 16 and the upper surface of the rail 20 that is large enough to prevent the mount from The frictional force relative to the movement of the guide rail in the extending direction of the installation slot. According to an exemplary embodiment of the present invention, the friction member 17 will provide the mounting part 10 with a frictional force preventing the mounting part 20 from moving relative to the guide rail in the extending direction of the mounting groove. In this way, the reduced requirement on the strength of the elastic element 16 makes it easier to install the mount on the rail, as will be described later.

According to an embodiment of the present invention, when the mounting part 10 is installed on the guide rail 20, the protruding stoppers 18 on the upper and lower mounting surfaces 12, 13 of the body 11 can pass against the upper side edge 24 and the lower side edge 24 of the guide rail. The side edge 21 prevents the guide rail 20 from detaching from the mounting groove. The lower side edge 21 of the guide rail 20 is clamped in the gap between the stopper 18 and the rib 19 on the lower installation surface 13, and the upper side edge 24 of the guide rail 20 is clamped by the stopper 18 and the friction member on the upper installation surface 17 in the gap between. The height of the friction member 17 protruding from the side mounting surface 14 is set so that the width of the gap between the stopper 18 on the upper mounting surface and the surface of the friction member 17 is smaller than the thickness of the upper side edge 24 of the guide rail, so that when the upper side of the guide rail When the edge 24 is stuck in the gap between the stopper 18 and the friction member 17 on the upper mounting surface, due to the elasticity or flexibility of the friction member, the upper side edge 24 of the guide rail 20 compresses the friction member 17 and deforms toward the side mounting surface, and the friction member The elastic restoring force makes the upper side edge 24 of the guide rail clamped between the friction member 17 and the stopper 18 of the upper mounting surface. In this way, the mount is fixed relative to the rail in a direction perpendicular to the side mounting surface. At the same time, due to the normal pressure perpendicular to the side mounting surface between the upper side edge 24 of the guide rail and the friction piece 17, and the high friction coefficient of the friction piece 17, when trying to move the mounting piece along the extending direction of the mounting groove, the friction piece will 17 and the upper side edge 24 of the guide rail 20 generate sufficient frictional force to prevent the mounting part from moving relative to the guide rail in the extending direction of the mounting groove.

Through the above-mentioned cooperation between the mounting part and the guide rail, the mounting part and the programmable controller fixedly connected to it are reliably fixed relative to the guide rail in three mutually perpendicular spatial directions. Furthermore, since the mount is in contact with the rail through a resilient element, usually made of conductive metal, there is an electrically conductive connection between the mount (and the programmable controller connected thereto) and the rail. This provides good grounding for electrical equipment secured to the mount.

The process of installing the mounting part 10 to the guide rail 20 will be described below with reference to FIG. 4 , and thus the advantages of the mounting part will be shown. The user first tilts the programmable controller 1 with the mounting part 10 close to the guide rail 20, wherein the upper part of the mounting part is close to the guide rail, while the lower part of the mounting part is away from the guide rail, and the upper side edge of the guide rail is installed toward the friction part 17 and the upper part of the mounting part. Insert in the gap between the stoppers 18 on the surface 12, and apply force to the friction member 17 toward the side mounting surface 14 of the installation groove in an oblique direction, so that the friction member 17 deforms and the gap widens for the upper side of the guide rail. Edge enters. At this moment, the user exerts downward force on the programmable controller again, so that the elastic element 16 on the mounting part 10 contacts the upper surface of the guide rail 20 and is compressed. Under the combined action of these two forces in different directions, the mounting groove and the entire programmable controller move down a small distance, and the upper side edge 24 of the guide rail is completely inserted between the friction member 17 and the stopper 18 on the upper mounting surface in the gap. Since the friction member 17 is a relatively easily deformable material, the user only needs to apply a small force to the side mounting surface in an oblique direction to deform the friction member. Moreover, since the elastic element 16 is configured to not provide enough frictional force for the mounting part to prevent it from moving in the extending direction of the installation slot, the force exerted downward to overcome the resistance of the elastic element is relatively small. Therefore, this installation step does not require much effort on the part of the user and is thus relatively easy and user-friendly.

The user then pushes the lower part of the mount closer to the rail 20 so that the lower side edge 21 of the rail 20 goes over the stop on the lower mounting surface of the mounting groove into the mounting groove and contacts the rib 19 on the side mounting surface. After the lower side edge of the guide rail has been positioned in the installation groove, the user no longer presses down on the programmable controller, but still maintains a horizontal thrust on the programmable controller. Because there is no downward external force, the restoring force of the elastic element 16 makes it return to elongate to a certain length, and supports the programmable controller and makes it move upwards, so that the lower side edge 21 of the guide rail is fully inserted into the ribs 19 and between stops 18 on the lower mounting surface. At this time, the guide rail 20 is completely caught by the installation groove of the installation part, and the installation is completed.

For the situation that the friction member 17 is arranged close to the lower mounting surface 13, after the upper side edge 24 of the guide rail has been inserted into the stopper 18 of the upper mounting surface, it is necessary to align the mounting member inwardly in the direction perpendicular to the side mounting surface. The lower part exerts force, so that the lower side edge 21 of the guide rail presses the friction member 17 close to the lower mounting surface 13, and then cancels the active force on the mounting part in the vertical direction at the same time, so that the mounting part and the programmable controller are pressed by the elastic element 16 The restoring force is supported, so that the lower side edge 21 of the guide rail enters into the gap widened between the stopper 18 and the friction member 17 of the lower mounting surface of the mounting part due to the friction member 17 being squeezed. Thereby, the lower part of the mounting part is also fixed in the direction perpendicular to the side mounting surface, and since the friction part 17 close to the lower mounting surface 13 is also pressed, it is also when the mounting part tries to move longitudinally relative to the guide rail. The mount provides longitudinal friction to resist movement.

According to an exemplary embodiment of the present invention, by using force applying members with different physical characteristics of vertical fastening force and frictional force, the role of the elastic element is simplified, thereby reducing the relatively large force applied to one member Split into relatively small forces in both directions. In this way, the user only needs less force to complete the installation, thereby improving the installation efficiency and improving the user experience of the installation.

The mounting part structure of the embodiment of the utility model can be used in various occasions where objects need to be fixed to the guide rail. The mount is preferably formed as a back plate. The backboard can be used to install various devices, preferably electronic, electric and electrical devices such as programmable controllers.

The embodiment of the utility model also discloses a guide rail installation structure, which includes a guide rail 20 and the above-mentioned installation part 10 . The mount 10 is mounted to the rail 20 such that the rail compresses the elastic element 16 towards the upper mounting surface and the friction member 17 towards the side mounting surface. Guide rails are usually provided in fixed places such as control cabinets. Items such as equipment connected to the mounting part can be fixedly connected to a fixed place such as a control cabinet through the guide rail installation structure.
