Description

TECHNICAL FIELD

[0001] The utility model relates to the field of composite steel plate fixing, especially to a detachable connecting anti-dropping device for metal-based composite steel plate. BACKGROUND

[0002] Composite steel plate is a material combined by two or more different steel plates through a specific process. It combines the advantages of different materials, such as high strength, corrosion resistance, wear resistance, light weight, etc., and is widely used in various industrial fields.

[0003] Bolt fixing is a common fixing method for composite plates, that is, holes are opened on the composite plate for the bolts to pass through, and then nuts are used to lock the composite plate to achieve the fixation of the composite plate. However, there are still the following defects and deficiencies in the application process:

[0004] In multiple composite plates, if the plate located at the top or bottom layer is subjected to a horizontal or horizontal-directional force, the plate may have a movement trend relative to other plates; and since it is only limited by the bolt, the screw needs to bear this external force, causing the bolt to be easily damaged or deformed, reducing its service life, and making it difficult to disassemble later.

[0005] Therefore, it is necessary to provide a new detachable connecting anti-dropping device for metal-based composite steel plate to solve the above technical problems. SUMMARY

[0006] To solve the above technical problems, the utility model provides a detachable connecting anti-dropping device for metal-based composite steel plate.

[0009] The locking assembly is composed of two symmetrical locking frames;

[0010] The two sets of locking frames are fixed by first bolts, and the locking frames are fixed on the composite plate body by second bolts.

[0011] Preferably, the locking frame comprises a positioning plate, one end of the positioning plate is welded and fixed with a clamping plate, the clamping plate is attached to the upper surface or lower surface of the composite plate body, and is fixed on the composite plate body by the second bolt.

[0012] Preferably, a plurality of reinforcing seats are welded and fixed on one side of the positioning plate, the reinforcing seats in the two groups of locking frames are vertically corresponding, and are fixed by the first bolt.

[0013] Preferably, a hexagonal embedding groove is further formed on the clamping plate and the reinforcing seat in the locking frame, and a nut is embedded in the hexagonal embedding groove and fixed with the bolt.

[0014] Preferably, the positioning plate in the locking assembly at the corner position is two sections, and the two sections of the positioning plate are attached to two adjacent sides of the composite plate body.

[0015] Preferably, the positioning plate in the locking assembly at the side position is one end, and the positioning plate is attached to one side of the composite plate body.

[0016] Compared with the related art, the metal-based composite steel plate detachable connection anti-dropping device has the following beneficial effects:

[0017] In the metal-based composite steel plate detachable connection anti-dropping device, two locking frames are fixed on the composite plate body by second bolts to fix the composite plate by clamping; meanwhile, the positioning plate is attached to the side of the composite plate, which can further improve the limiting effect on the composite plate and can share external force to reduce the damage to the bolts.

It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0027] The specific implementation of the utility model will be described in detail below in combination with specific examples.

[0028] Please refer to Figures 1 to 3 The metal-based composite steel plate detachable connection anti-dropping device provided by the utility model embodiment comprises a composite plate body 1.

[0029] A plurality of sets of locking assemblies 2 are fixed at the corners and side positions of the composite plate body 1.

[0030] The locking assembly 2 is composed of two symmetrical locking frames 21.

[0031] The two sets of locking frames 21 are fixed through first bolts 22, and the locking frame 21 is fixed on the composite plate body 1 through a second bolt 23.

[0032] It should be noted that: the locking assembly 2 is used for fixing the main structure of the composite board body 1, which is a plurality of sets, installed on the edge and side of the composite board body 1, and can resist the side wall of the composite board body 1, so that when any one composite board has a movement trend under the action of external force, the locking assembly 2 can offset the external force, and the limiting effect on the composite board body 1 is better, and the protection effect on the bolt is improved;

[0033] The locking assembly 2 is composed of two groups of locking frames 21, and the two groups of locking frames 21 are connected by the first bolt 22 to form a complete frame structure, and the spacing between the two groups of locking frames 21 can be adjusted by the first bolt 22, so that when the two groups of locking frames 21 abut against the upper and lower surfaces of the composite board body 1, the composite board body 1 can be clamped, and the spacing between the two groups of locking frames 21 can be adjusted to adapt to composite board bodies 1 of different thicknesses, and the application range is larger;

[0034] The locking frame 21 is fixed on the composite board body 1 by the second bolt 23, so that the locking frame 21 and the composite board body 1 are stably connected.

[0035] In the embodiment of the utility model, please refer to Figures 1 to 3 The locking frame 21 comprises a positioning plate 211, and the positioning plate 211 is welded and fixed with a clamping plate 212 at one end, and the clamping plate 212 is attached to the upper surface or the lower surface of the composite board body 1 and is fixed on the composite board body 1 by the second bolt 23.

[0036] A plurality of reinforcing seats 213 are welded and fixed on one side of the positioning plate 211, and the reinforcing seats 213 in the two groups of locking frames 21 are vertically corresponding and are fixed by the first bolt 22.

[0037] The clamping plate 212 and the reinforcing seat 213 in one group of locking frames 21 are further provided with a hexagonal slot 214, and a nut is embeddedly fixed in the hexagonal slot 214 and is fixed with the bolt.

[0038] It should be noted that: when the locking frame 21 is installed and fixed, first, the positioning plate 211 is attached to the side of the composite board body 1, so that the hole for penetrating the bolt on the locking frame 21 corresponds to the hole on the composite board body 1, then the first bolt 22 is rotated to reduce the spacing between the two groups of locking frames 21, until the clamping plate 212 is attached to the upper end surface or the lower end surface of the composite board body 1, until the composite board body 1 is clamped tightly, and finally the clamping plate 212 is fixed on the composite board body 1 by the second bolt 23.

[0039] The positioning plate 211 mainly contacts the side of the composite board body 1, so that when the composite board body 1 is subjected to force, the positioning plate 211 can play a role in resisting pressure.

[0040] In the embodiment of the utility model, please refer to Figures 1 to 3 The positioning plate 211 is two sections, and the two sections of the positioning plate 211 are attached to two adjacent sides of the composite board body 1 in the locking assembly 2 at the corner position.

[0041] The positioning plate 211 is one end, and the positioning plate 211 is attached to one side of the composite board body 1 in the locking assembly 2 at the side position.

[0042] It should be noted that: the number of locking assemblies 2 used is mainly determined according to the size of the composite board body 1, but it is always necessary to install at the corner position, and the number at the side position can be appropriately adjusted to ensure the stable fixation of the composite board body 1.

[0043] The circuit and control involved in the utility model are prior art, and will not be described in detail here.

[0044] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
