Abstract
Description
Technical Field
[0001] This utility model belongs to the field of geotechnical engineering investigation, and more specifically, it relates to a portable enclosure device for geotechnical engineering investigation. Background Technology
[0002] Geotechnical engineering investigation enclosures are temporary barriers used during geotechnical engineering investigations. Their main function is to isolate the investigation site from the external environment, creating a relatively closed working environment to ensure safety and maintain order during the investigation. Currently, traditional geotechnical engineering investigation enclosures typically consist of two sets of pillars vertically supporting a set of panels. To ensure adequate coverage of the construction site, the panels are often large, flat, integral structures. This fixed flat structure means the panels cannot be scaled down or adjusted, resulting in significant space requirements during transportation and storage. Consequently, carrying the enclosure equipment during geotechnical engineering investigations is extremely inconvenient. Utility Model Content

[0033] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0034] like Figures 1-14As shown, this utility model provides a portable enclosure device for geotechnical engineering exploration, including a fixing plate 6 and a baffle 1; the fixing plate 6 and the baffle 1 are hinged; it also includes a locking post device 4 and a connecting post 5; the locking post device 4 includes a locking post housing 401, an insert plate 402, a locking block 403, a knob 404, a bidirectional threaded rod 405, a driving bevel gear 406, a driven bevel gear 407, a transmission rod 408, and a first foot plate 409; the fixing plate 6 is welded to the right side of the locking post housing 401, the insert plate 402 is welded to the left side of the locking post housing 401, a handrail 3 is welded to the rear side of the locking post housing 401, the first foot plate 409 is welded to the rear side of the locking post housing 401 near the bottom, a through hole is provided at the center of the rear side of the locking post housing 401, and the transmission rod 408 is rotatably connected in the through hole of the locking post housing 401. A knob 404 is installed at the rear end of the transmission rod 408. A drive bevel gear 406 is welded to the rear end of the transmission rod 408. A driven bevel gear 407 is meshed with the outer side of the drive bevel gear 406. A bidirectional threaded rod 405 is welded to the inner side of the driven bevel gear 407. A locking block 403 is meshed with the outer side of the bidirectional threaded rod 405. The connecting column 5 includes a column body 501, a locking plate 502, a connecting plate 503, and a second foot plate 504. A connecting plate 503 is welded to the right side of the column body 501. The connecting plate 503 has a trapezoidal groove structure. A locking plate 502 is bolted to the front side of the column body 501. A fixing plate 6 is welded to the left side of the column body 501. A handrail 3 is welded to the rear side of the column body 501. A second foot plate 504 is welded to the rear side of the column body 501 near the bottom.
[0035] In this embodiment, there are four sets of baffles 1. Each set of baffles 1 has a magnetic strip 2 attached to its left and right sides. The four sets of baffles 1 are hinged to each other. Through the hinge structure of the four sets of baffles 1, the four sets of baffles 1 can be flipped and folded to reduce the area of the baffles 1 and make it easier to store and carry. When the four sets of baffles 1 are flipped and unfolded, the magnetic strips 2 attached to the four sets of baffles 1 attract each other to ensure that the four sets of baffles 1 maintain a stable and unfolded planar state.
[0036] In this embodiment, there are two sets of insert plates 402. Each set of insert plates 402 has a trapezoidal protrusion at the center of its left side. The trapezoidal protrusion of the insert plate 402 is embedded in the trapezoidal groove of the connecting plate 503, forming a quick-connecting horizontal locking connection between the locking shell 401 of one set of enclosures and the column 501 of another set of enclosures. The connection and dismantling of multiple sets of enclosures is simple and quick.
[0037] In this embodiment, a rectangular through groove is provided at the center of the front side of the lock pin housing 401. The lock block 403 is inserted into the rectangular through groove of the lock pin housing 401. The left side and right side of the lock block 403 are respectively attached to the left and right groove walls of the rectangular through groove of the lock pin housing 401, so that the rectangular through groove of the lock pin housing 401 supports the lock block 403 to slide vertically.
[0038] In this embodiment, the locking plate 502 is a T-shaped opening groove structure that runs vertically through the top and bottom. The T-shaped structure of the locking block 403 is interlocked with the T-shaped opening groove of the locking plate 502. The T-shaped opening groove of the locking plate 502 nests and locks the T-shaped locking block 403, preventing the baffle 1 from flipping open and ensuring that the baffle 1 is stably folded and stored.
[0039] In this embodiment, there are two sets of locking blocks 403, which are symmetrically distributed vertically. Each set of locking blocks 403 has a T-shaped structure and a threaded through hole that runs vertically through the locking block 403. The forward threaded end of the outer side of the bidirectional threaded rod 405 is engaged with the threaded through hole of the upper locking block 403, and the reverse threaded end of the outer side of the bidirectional threaded rod 405 is engaged with the threaded through hole of the lower locking block 403. The bidirectional threaded rod 405 drives the two sets of locking blocks 403 to move vertically and oppositely along the rectangular through groove of the locking pin shell 401, so that the two sets of locking blocks 403 simultaneously penetrate into the T-shaped groove structure of the locking plate 502 to lock the locking pin shell 401 and the pin 501. The locking operation is simple and quick.
[0040] The specific usage and function of this embodiment are as follows:
[0041] When folding and storing the baffle 1, the four sets of hinged baffles 1 are first flipped and folded. Then, the two sets of handles 3 are held with both hands to drive the lock cylinder shell 401 and the cylinder 501 to flip in opposite directions, so that the T-shaped groove structure of the lock plate 502 is aligned with the T-shaped through groove structure of the lock cylinder shell 401. Then, the knob 404 is manually turned, which drives the drive bevel gear 406, which is welded to the transmission rod 408, to rotate synchronously. Since the outer side of the drive bevel gear 406 is meshed with the driven bevel gear 407, the drive bevel gear 406 drives the bidirectional threaded rod 405, which is welded to the driven bevel gear 407. Rotation causes the two sets of locking blocks 403 to move together vertically along the rectangular through slot of the locking pin shell 401. The T-shaped locking blocks 403 are then inserted into the T-shaped groove of the locking plate 502 to fold and lock the four sets of baffles 1, thus completing the folding and storage of the enclosure. When multiple enclosures are assembled, the trapezoidal protrusion of the insert plate 402 welded to the locking pin shell 401 is inserted from top to bottom into the trapezoidal opening groove of the connecting plate 503, thus completing the rapid assembly of multiple enclosures.
[0042] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient specifications of all components are based on their own technology; any method that achieves the desired effect can be implemented. The magnet strip 2, handrail 3, and knob 404 mentioned above are all common market components. When purchasing and using them, simply follow the instruction manual provided with the purchase; therefore, further details are omitted here.
