Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated components, in particular to a prefabricated component splicing structure. Background Art

[0002] Prefabricated components are components that are pre-made in a factory or on site. Their characteristic is that they are completed in advance and then transported to the construction site for installation. This production method is conducive to improving construction efficiency, reducing construction costs, and ensuring the quality of components. Prefabricated panels are needed for splicing and construction in areas such as advertising boards and exhibition stands.

[0003] Existing prefabricated panels are spliced ​​together through matching plug-in structures such as plug-ins and slots, and then fixed by fasteners such as bolts. However, this splicing structure is not convenient for adjusting the angle. For example, in the field of advertising boards and exhibition stands, an overall structure with an angle is set for visual effects, making it more eye-catching when looking from multiple directions. This makes the existing prefabricated panel splicing structure unable to be applied in the above-mentioned fields, or requires secondary processing to achieve, which is more troublesome.

[0008] Through the arrangement of the insertion rod and the reset member of the utility model, it is possible to select the pin and the corresponding positioning groove for cooperation and insertion according to the angle that needs to be adjusted between the two prefabricated panels, and directly lock the angle. After the angle is locked, the reset member can prevent the pin and the positioning groove from loosening and disengaging, thereby realizing multi-angle splicing.

[0009] Among them, the provision of the latch and the positioning groove enables the two prefabricated panels to be locked after adjusting the angle, thereby completing the locking of the angle.

[0010] Among them, the setting of the reset member makes it impossible for the latch to be separated from the positioning groove after being plugged in and matched, thereby ensuring the stability of the splicing structure.

[0018] In the utility model, the setting of the slider allows the operator to easily retract the latch into the groove, thereby facilitating the unlocking of the insertion rod.

[0019] Preferably, a surface of the sliding block facing the outside of the sliding groove is concave.

[0020] In the utility model, the outer surface of the sliding block is arranged in a concave shape, so that the operator can slide the sliding block conveniently, thereby improving the operating efficiency.

[0028] In order to further understand the content of the utility model, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0029] Example 1

[0030] like Figure 1-5 As shown, this embodiment provides a prefabricated component splicing structure, which includes a first fixing block 111 arranged at one prefabricated plate, and a second fixing block 121 arranged at another prefabricated plate;

[0031] One end of the first fixed block 111 is provided with an insertion rod 112, and one end of the second fixed block 121 is provided with a slot 122 for the insertion rod 112 to extend into; a plurality of positioning grooves 113 distributed circumferentially along the insertion rod 112 are provided on the side wall of the insertion rod 112; a latch 325 cooperating with the positioning groove 113 is provided at the second fixed block 121; a reset member 330 is also provided at the second fixed block 121, and the reset member 330 is used to push the latch 325 into the positioning groove 113.

[0032] Through the arrangement of the insertion rod 112 and the reset member 330 in this embodiment, it is possible to select the latch 325 and the corresponding positioning groove 113 for cooperation and insertion according to the angle that needs to be adjusted between the two prefabricated panels, and directly lock the angle. After the angle is locked, the reset member 330 can prevent the latch 325 from loosening and disengaging from the positioning groove 113, thereby realizing multi-angle splicing; wherein each panel can be provided with a first fixing block 111 or a second fixing block 121 on both sides to realize the splicing of multiple prefabricated panels with each other.

[0033] In this embodiment, the prefabricated plate provided with the second fixing block 121 is provided with a groove 323, which is located at the side wall of the prefabricated plate and is used to accommodate the pin 325. The reset member 330 includes a spring 324 abutting against the inner end of the groove 323, and the other end of the spring 324 faces the outer end of the groove 323 and abuts against one end of the pin 325.

[0034] By providing the spring 324 in this embodiment, the latch 325 can be automatically extended, so that it can be plugged into any positioning slot 113 .

[0035] In this embodiment, the second fixing block 121 is provided with through holes 329 penetrating both sides. The through holes 329 are coaxial with the groove 323 . One end of the latch 325 away from the spring 324 passes through the through holes 329 and extends into the slot 122 .

[0036] By setting the through hole 329 in this embodiment, the spring 324 and the pin 325 can be assembled into the groove 323 through the through hole 329, and at the same time, one end of the pin 325 can be placed in the slot 122, so as to realize the plug-in fit between the pin 325 and the positioning slot 113; wherein the two ends of the through hole 329 simultaneously pass through the opposite sides of the polygonal slot 122, so that the pin 325 can pass through one end of the through hole 329 and be plugged into the positioning slot 113 on either side of the insertion rod 112.

[0037] In this embodiment, a section of the latch 325 located inside the slot 122 is provided with a guide surface 526 , and the guide surface 526 faces the outer end of the slot 122 .

[0038] By setting the guide surface 526 in this embodiment, after the insertion rod 112 is inserted into the slot 122, the guide surface 526 of the latch 325 can retract the latch 325 into the groove 323, so that there is no need to manually adjust the position of the latch 325 when locking the insertion rod 112.

[0039] In this embodiment, the prefabricated plate with the second fixing block 121 is provided with a slide groove 127 , which is located on one side of the prefabricated plate and is connected to the groove 323 , and a slider 128 connected to the latch 325 is slidably connected in the slide groove 127 .

[0040] By setting the slider 128 in this embodiment, the operator can easily retract the latch 325 into the groove 323, so as to facilitate the unlocking of the insertion rod 112. The slider 128 and the side wall of the latch 325 can be opened and connected by fasteners.

[0041] In this embodiment, a surface of the sliding block 128 facing the outside of the sliding groove 127 is concave.

[0042] The slider 128 in this embodiment is concavely arranged on the outside, so that the operator can slide the slider 128 conveniently, thereby improving the operating efficiency.

[0043] In this embodiment, the cross section of the insertion rod 112 is a regular polygon, and can be any one of a regular quadrilateral, a regular hexagon, a regular octagon, a regular decagon, a regular dodecagon, a regular tetradecagon, and a regular hexadecagon.

[0044] By setting the cross-section of the insertion rod 112 in this embodiment to be a regular polygon, the insertion rod 112 has multiple edges and corners that cooperate with the slot 122. After adjusting the angle, the angle can be locked by directly plugging it in. The multi-angle structure can ensure the structural strength, thereby ensuring the splicing strength of the two prefabricated panels.

[0045] When a prefabricated component splicing structure of this embodiment is used, first determine the angle that needs to be adjusted between the two prefabricated panels, adjust the insertion rod 112 and the slot 122 to a certain angle and then plug them together, so that the two prefabricated panels automatically complete the angle locking. Taking the regular octagonal insertion rod 112 as an example, the insertion rod 112 can be adjusted 45° each time it rotates one face. When the insertion rod 112 is plugged into the slot 122, one end of the pin 325 is placed in the slot 122 and a guide surface 526 is provided, so the insertion rod 112 will contact the guide surface 526 of the pin 325 and push the pin 325 into the groove 323, while compressing the spring 324. When the insertion rod 112 is completed, the pin 325 can correspond to the positioning groove 113. At this time, the spring 324 recovers and pushes the end of the pin 325 into the positioning groove 113, locking the insertion rod 112 in the slot 122 to complete the splicing; when disassembling, slide the slider 128 to retract the pin 325 into the groove 323, and directly pull the insertion rod 112 out of the slot 122.

[0046] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0047] The present invention and its implementation methods are described schematically above, and the description is not restrictive. The embodiments shown in the embodiments are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the embodiments and designs a structure and an implementation method similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
