Description

Technical Field

[0001] The utility model relates to the technical field of micro-pressure oxygen chamber equipment, in particular to a connecting device for splicing plate bodies. Background Art

[0002] As people's health awareness becomes stronger and stronger, micro-compression oxygen chambers, as a health-care consumer product, are mostly installed in homes, shopping malls, clubs and other places. Due to the large size of the cabin, it cannot be shipped as a whole and needs to be installed and debugged at the site of use. The existing micro-compression oxygen chamber cabin connection methods are mainly overlapped or butt-jointed. The overlap connection method is that the two plates overlap at the contact position, and the plates are fixed by bolts perpendicular to the plates. In this way, when the cabin is under pressure, there is a relative displacement of the overlap surface, and the cabin often has obvious noise, affecting the user experience. The butt connection method is that the two plates are butt-jointed sideways, and the plates are fixed by connecting bolts parallel to the plates. In this way, when the cabin is under pressure, there is no relative displacement of the contact surface, and the cabin noise is small, but this type of structure is subject to greater force on the bolts, and the reliability of the bolt connection is required to be higher. At present, most of the butt connection methods on the market have bolt holes on the side of the plate, and the plates are connected and tightened by bolts, gaskets and nuts. This method requires bolts to be inserted and tightened one by one at the installation site, which takes a long time.

[0003] In view of the above reasons, it is necessary to provide a connecting device for splicing panels that reduces the on-site installation period to solve the problems in the prior art. Utility Model Content

The splint is bent into a U-shape, the plates on both sides of the U-shaped splint are parallel, the end points of the U-shaped splint are turned outward, and through holes are provided on both side surfaces of the U-shaped splint. The bolts pass through the through holes and are tightened with the nuts on the other side of the U-shaped splint.

[0005] Preferably, the width between the two ends of the U-shaped splint is greater than the width of the U-shaped splint body, and the two ends of the U-shaped splint are outward-expanding structures.

[0006] Preferably, nuts or bolts are fixed on the side surfaces of the U-shaped clamping plate.

[0007] The utility model provides a connecting device for splicing plates, including a clamp and a bolt. The clamp is bent into a U-shape, the plates on both sides of the U-shaped clamp are parallel, the ends of the U-shaped clamp are turned outward, through holes are provided on both sides of the U-shaped clamp, the bolts pass through the through holes and are tightened with nuts on the other side of the U-shaped clamp.

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0014] See also Figure 1 to Figure 2 The preferred embodiment of the utility model provides a connecting device for splicing plates, including a clamping plate 1, a nut 2 and a bolt 3. The clamping plate 1 is bent into a U-shape, the two side plates 13 of the U-shaped clamping plate 1 are parallel, and the end point 12 of the U-shaped clamping plate is turned outward. Through holes 11 are provided on the two side surfaces of the U-shaped clamping plate 1. The bolt 3 passes through the through holes 11 and is tightened with the nut 2 on the other side of the U-shaped clamping plate 1. Here, the nut 2 is a welding nut, which is welded to any outer side of the two side plates 13. The nut 2 is welded to the U-shaped clamping plate 1 as a whole, and the surface is galvanized after welding.

[0015] Preferably, the width between the two ends 12 of the U-shaped clamping plate 1 is greater than the width of the U-shaped clamping plate body 13, and the two ends 12 of the U-shaped clamping plate 1 are outward expansion structures. In this embodiment, the U-shaped opening angle is relatively large, which has a guiding effect during installation.

[0016] Preferably, the nut 2 or the bolt 3 is fixed on the side surface of the U-shaped clamping plate 1 .

[0017] Please refer to Figure 3 The connecting device for splicing the panels provided in this embodiment is installed on the outer frame profile of the panel. Taking the profile 4 as an example, a slot 41 is provided at the joint of two adjacent profiles 4, and the slot 41 has a joint side wall 42.

A notch 43 is provided on the joint side wall 42, and the upper end of the notch 43 is open.

[0018] Specifically, the bolt 3 is a screw structure matched with the nut 2. In this embodiment, the bolt 3 is a hexagonal flange bolt. In other embodiments, the bolt 3 can be other shapes that can be tightened, and the utility model does not limit this.

[0019] The connection device for splicing plates provided in the preferred embodiment of the utility model is used as follows. The bolt 3 is pre-placed in the through hole 11 opposite to the nut 2 of the U-shaped clamp 1, and the bolt 3 is not tightened at this time. At the installation site, the pre-installed connection device is inserted into the slot 41, and the bolt 3 enters the notch 43 from the upper end. Tightening can be achieved by rotating the bolt 3 about half a turn with a wrench, which is convenient and quick. In addition, the parallel plate bodies 13 on both sides of the U-shaped clamp 1 can clamp the butt side walls 42 of the two profiles to restrict the bell mouth from opening when the two profiles are stressed, thereby enhancing reliability.
