In confined spaces or areas with limited access, bolt installation and tightening become even more difficult, increasing construction complexity and time costs. Furthermore, the tightness of bolts is difficult to visually inspect, necessitating professional testing methods to ensure connection quality. Consequently, bolted connections offer limited flexibility in application. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This utility model provides, for example Figure 1-5The precast concrete component shown includes: a precast component body 1, wherein the precast component bodies 1 are detachably spliced ​​together; a snap-fit ​​splicing device 2, which is installed on one side of the precast component body 1, and a groove is provided on the other side of the precast component body 1 to mate with it. A filler block 11 is installed inside the groove, which facilitates the interaction with the inner cavity of the mounting base 21, making the fit between the mounting base 21 and the groove more stable. A slot is provided on the side of the groove, and the precast component bodies 1 are connected by the snap-fit ​​splicing device 2 and the slot. Locking connection; unlocking device 3, the unlocking device 3 is installed at the corner of the other side of the precast component body 1, and the unlocking device 3 is used to unlock the snap-fit ​​splicing device 2. By fitting the snap-fit ​​splicing device 2 into the inner cavity of the groove, the telescopic snap-fit ​​mechanism 22 is elastically snapped into the inner cavity of the slot inside the precast component body 1, so as to realize the movable snap-fit ​​between the precast component body 1 and the mounting base 21. Thus, the detachable splicing installation between the precast component bodies 1 can be realized, while avoiding the disadvantages of using bolt connection, making the connection between the precast component bodies 1 more flexible. Example

[0041] The snap-fit ​​splicing device 2 includes: a mounting base 21, which is fixedly installed on the precast component body 1; a detachable snap-fit ​​component, which is used for the interlocking snap-fit ​​of the precast component body 1, and includes: a telescopic snap-fit ​​mechanism 22, which is slidably interlocked with the mounting base 21; and an elastic support mechanism 23, which is slidably interlocked with the telescopic snap-fit ​​mechanism 22 and provides elastic support for the telescopic snap-fit ​​mechanism 22. The snap-fit ​​between the telescopic snap-fit ​​mechanism 22 and the inner cavity of the slot facilitates the splicing of the relative positions of the precast component bodies 1, making the connection between the precast component bodies 1 more flexible. The telescopic interlocking between the elastic support mechanism 23 and the telescopic snap-fit ​​mechanism 22 provides elastic support for the telescopic snap-fit ​​mechanism 22, allowing the telescopic snap-fit ​​mechanism 22 to elastically snap into the inner cavity of the slot. The corresponding position of the mounting base 21 and the groove facilitates higher relative connection accuracy between the precast component bodies 1.

[0042] Furthermore, the telescopic snap-fit ​​mechanism 22 includes: a sliding sleeve 221, which is movably disposed inside the mounting base 21; and a snap-fit ​​block 222, which is installed at the end of the sliding sleeve 221. The snap-fit ​​block 222 is slidably inserted into one end of the mounting base 21, and the head of the snap-fit ​​block 222 cooperates with the inner cavity of the slot. Through the cooperation between the snap-fit ​​block 222 and the inner cavity of the slot, a one-way snap-fit ​​between the precast component body 1 and the precast component body 1 is realized. Through the sliding insertion of the insertion rod 231 and the sliding sleeve 221, a sliding space is provided for the relative sliding between the insertion rod 231 and the sliding sleeve 221.

[0043] Furthermore, the elastic support mechanism 23 includes: a through rod 231, one end of which is slidably connected to the inner cavity of the sliding sleeve 221; a spring 232, which is movably sleeved on the outside of the through rod 231; a mounting plate 233, which is fixedly connected to the other end of the through rod 231; and positioning blocks 234, multiple positioning blocks 234 mounted on the mounting plate 233. The other end of the mounting base 21 has a positioning groove, and the positioning blocks 234 cooperate with the inner cavity of the positioning groove. The through rod 231 facilitates the adjustment of the spring 231. The deformation of spring 232 is guided by the compression deformation of spring 232, which facilitates the elastic support of sliding sleeve 221 to achieve elastic engagement of locking block 222. The mounting plate 233 facilitates the installation of positioning block 234. Through the mutual cooperation between positioning block 234 and positioning groove, and the elastic support of mounting plate 233 by spring 232, positioning block 234 is stably engaged in the inner cavity of positioning groove, which facilitates the installation and removal of positioning block 234 and the replacement of spring 232 when it is overused. Example

[0044] Based on Embodiment 1, the unlocking device 3 includes: a pressing mechanism 31, which is slidably disposed inside the precast component body 1 and corresponds to the position of the snap-fit ​​splicing device 2; and a blocking mechanism 32, which is movably embedded in the corner of the precast component body 1. The pressing mechanism 31 facilitates the unlocking of the snap-fit ​​splicing device 2, and the blocking mechanism 32 facilitates the covering of the pressing mechanism 31 to protect the pressing mechanism 31.

[0045] The extrusion mechanism 31 includes: an extrusion column 311, which is slidably disposed inside the slot; and a slider 312, which is connected to the side of the extrusion column 311 and is slidably inserted into the precast component body 1. Through the sliding insertion of the extrusion column 311 into the slot cavity, when an external force presses the extrusion column 311, the extrusion column 311 extrudes the locking block 222, causing the locking block 222 to move towards the mounting base 21 and thus disengage from the slot cavity, thereby unlocking the locking block 222. The sliding of the slider 312 facilitates the limiting of the sliding of the extrusion column 311, making the linear movement of the extrusion column 311 more stable.

[0046] The shielding mechanism 32 includes: a protective baffle 321, which is rotatably embedded in the corner of the precast component body 1; and a retaining ball 322, which is connected to the end of the protective baffle 321 and is movably engaged with the precast component body 1. The protective baffle 321 rotates and covers the end of the extrusion mechanism 31, which facilitates the protection of the extrusion mechanism 31. The retaining ball 322 is spherical and has an opening at its bottom, which makes the movable engagement between the retaining ball 322 and the precast component body 1 more flexible. The retaining ball 322 facilitates the positioning of the protective baffle 321.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
