Description

Technical Field

[0001] The utility model relates to the technical field of guide rail fastening, in particular to a DIN guide rail buckle fastening structure. Background Art

[0002] DIN rails provide a standardized support and fixing structure for electrical and industrial control equipment, making the equipment easier to integrate, maintain and upgrade. In the prior art, some electrical components or equipment are connected to the DIN rails more stably using snap-on fastening structures. For example, when a coupler is directly connected to the DIN rail, it may be troublesome to perform later maintenance and adjustment, and its practicality is too low. Generally, a snap-on fastening structure is used to connect to the DIN rail to facilitate later maintenance and repair. However, some snap-on fastening structures will have certain friction when adjusting the position of the outer wall of the DIN rail, causing wear of the snap-on fastening structure or the surface of the DIN rail, thereby reducing the service life.

[0003] Chinese patent announcement number: CN215301194U discloses a DIN35 rail mounted bus coupler, which relates to the technical field of couplers. The coupler is provided with a connection seat for connecting to the DIN rail at the bottom, a connection mechanism is provided on the connection seat, the connection mechanism includes a connection groove, the DIN rail is embedded in the connection groove, and extension pieces are provided on both sides of the DIN rail. The connection mechanism includes a connection piece and a movable piece for clamping the extension piece. When connected, the extension piece is located between the connection piece and the movable piece. A driving member for pushing the movable piece to slide toward the connection piece is provided in the connection seat. One end of the connection piece is rotatably connected to the bottom of the connection groove, and the connection piece is limited to rotate toward the outside of the connection groove by a limit plate that is movably connected. A connection mechanism is provided at the bottom of the coupler body, which can be connected to the DIN rail.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a DIN rail buckle fastening structure, comprising a connecting rail 1, a buckle fastening component 2 is arranged on the upper surface of the connecting rail 1, and a connecting device component 3 is arranged on the upper surface of the buckle fastening component 2;

[0032] The buckle fastening assembly 2 includes a rectangular shell 21, the lower surface of the rectangular shell 21 contacts the upper surface of the connecting guide rail 1, and a slide groove 27 is provided at the left end of the lower surface of the rectangular shell 21. When the L-shaped buckle 23 moves to the leftmost end of the slide groove 27, the L-shaped buckle 23 will no longer contact the connecting guide rail 1, and the buckle fastening assembly 2 can be removed quickly and conveniently. A groove 210 is provided on the right side of the lower surface of the rectangular shell 21 near the slide groove 27, and the inner wall of the slide groove 27 is slidably connected with the L-shaped buckle 23. When the L-shaped buckle 23 moves toward the connecting guide rail 1, the connecting guide rail 1 will be pushed downward by the inclined surface of the L-shaped buckle 23. At the same time, the rectangular shell 21 will also move downward, so that the ball 25 is retracted into the inner wall of the groove 210, so that the entire lower surface of the rectangular shell 21 contacts the upper surface of the connecting guide rail 1, thereby improving the connection stability, and the right surface of the L-shaped buckle 23 contacts the left surface of the connecting guide rail 1.

[0033] Reference Figure 1 - Figure 2 The connecting device assembly 3 includes a convex fixed shell 31, which is fixedly connected to the upper surface of the rectangular shell 21. The inner wall of the top of the convex fixed shell 31 is elastically connected to the slide plate 32 through a spring 2 34. The spring 2 34 always pushes the slide plate 32 to move to the left through its own elasticity to ensure the stability of the connecting device. The slide plate 32 is slidably connected to the inner wall of the top of the convex fixed shell 31. One end of the spring 2 34 is fixedly connected to the inner wall of the top of the convex fixed shell 31. Both sides of the top of the convex fixed shell 31 are set to rubber material to avoid damage to the device due to excessive hardness of the material. The other end of the spring 2 34 is fixedly connected to the right surface of the slide plate 32.

[0034] Reference Figure 2 , Figure 3The top of the front surface of the L-shaped buckle 23 is fixedly connected with a connecting block 24, and a through groove 26 is opened on the left side of the front surface of the rectangular shell 21. The connecting block 24 passes through the inner wall of the through groove 26 that is slidably connected. The left surface of the connecting block 24 passes through a two-way threaded rod 22 that is threadedly connected. The two-way threaded rod 22 is a prior art, and its outer wall has two groups of threads with different rotation directions. When rotating, the two groups of threaded connection structures will move relative or oppositely to ensure the synchronization of the cooperation between the structures. At the same time, it has the characteristics of left and right self-locking, making the connection more stable. The inner wall of the groove 210 is elastically connected to the connecting column 28 through a spring 29. The spring 29 29 itself has a certain elasticity and always pushes the connecting column 28 downward to ensure that when the two-way threaded rod 22 is loosened, the spring 29 will support the rectangular shell 21 through its own elasticity and make the ball 25 contact with the connecting guide rail 1, reducing the friction for adjusting the position of the equipment. The connecting column 28 is slidably connected to the inner wall of the groove 210, one end of the spring 29 is fixedly connected to the inner wall of the groove 210, and the other end of the spring 29 is fixedly connected to the upper surface of the connecting column 28. The lower surface of the connecting column 28 is rotatably connected with the ball 25, and the ball 25 rolls on the upper surface of the connecting guide rail 1. The right surface of the bottom end of the L-shaped buckle 23 is an inclined surface.

[0035] Reference Figure 2 A push handle 33 is fixedly connected to the right end of the front surface of the slide plate 32, and a through slot 2 35 is provided at the top of the front surface of the convex fixed shell 31. The push handle 33 penetrates and is slidably connected to the inner wall of the through slot 2 35. The left end of the slide plate 32 is made of rubber material. The rubber material enhances the stability of the equipment without causing damage to the equipment.

[0036] Working principle: When in use, when the snap fastening assembly 2 needs to be fixed on the connecting guide rail 1, it is necessary to first open the L-shaped snap 23 to the maximum, place the snap fastening assembly 2 on the upper surface of the connecting guide rail 1, make the ball 25 contact with the connecting guide rail 1, and then rotate the two-way threaded rod 22. At this time, the connecting block 24 will follow the rotation of the two-way threaded rod 22 and move horizontally. The connecting block 24 will drive the L-shaped snap 23 to move. When the L-shaped snap 23 contacts the connecting guide rail 1, the connecting guide rail 1 and the snap fastening assembly 2 can be simply connected together. In this state, when adjusting the position of the snap fastening assembly 2, the ball 25 will roll on the upper surface of the connecting guide rail 1, reducing friction. At the same time, it can be easily pushed without time or effort.

[0037] When locking is required, it is only necessary to rotate the two-way threaded rod 22, the two-way threaded rod 22 will drive the connecting block 24 to move, and the L-shaped buckle 23 will also move accordingly. At this time, the L-shaped buckle 23 will slowly move downward along the inclined surface, and the L-shaped buckle 23 will drive the rectangular shell 21 to move downward until the upper surface of the right end of the L-shaped buckle 23 contacts the lower surface of the connecting guide rail 1, the ball 25 will be retracted into the inner wall of the groove 210, and at the same time, the spring 29 will be squeezed through the connecting column 28, so that the buckle fastening assembly 2 can be locked. When the buckle fastening assembly 2 needs to be moved or removed again, it is only necessary to reverse the two-way threaded rod 22, and the subsequent structural coordination method is the same as above. At this time, the ball 25 will be elastically ejected from the inner wall of the groove 210 by the spring 29, which is quick and convenient and improves work efficiency.

[0038] When installing the equipment, you only need to push the slide plate 32, which drives the slide plate 32 to move and squeeze the second spring 34, and put the installation notch of the equipment on the upper surface of the convex fixed shell 31. Then, you can loosen the slide plate 32. The second spring 34 will push the slide plate 32 to move through its own elasticity, so that it contacts with the installation notch of the equipment to form a snap connection. When disassembling, you only need to push the second spring 34, which is quick and convenient, and improves work efficiency.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
