Description

Technical Field

[0001] This utility model relates to the field of access control installation technology, specifically to a pre-embedded access control base structure. Background Technology

[0002] In the field of building security, the installation quality of access control systems directly affects their effectiveness. However, the traditional installation method of access control bases has long had many drawbacks and cannot meet the needs of modern buildings for efficient, precise and stable construction.

[0003] When installing traditional access control bases, the lack of standardized guide and positioning structures means that the connection between the equipment and the base relies entirely on manual experience for adjustment, resulting in extremely poor positioning accuracy. Installers need to repeatedly compare the positions and disassemble and reassemble multiple times to barely align them. Positioning a single device takes a long time, severely slowing down the construction progress. Moreover, this method, which relies on manual visual inspection, is prone to horizontal deviation or angular tilt.

[0004] Meanwhile, traditional installation requires highly skilled workers, and novices often need to try to install it multiple times before they can complete the installation. Repeatedly tightening the bolts can also cause the screw holes in the base to strip, increasing maintenance costs. More importantly, the traditional base fixing method is not stable enough. It often uses surface bolt connections, which are greatly affected by the flatness of the wall surface. Even small protrusions on the tiled wall or the soft base of the plasterboard wall can cause the equipment to gradually loosen and sink after installation, resulting in permanent deviations and even safety hazards.

[0005] In addition, traditional installations do not use pre-embedded design, resulting in limited connection strength between the base and the wall. They are prone to loosening under external impact during long-term use. Moreover, multiple drilling and adjustments are required in the wall during construction, which not only damages the building's aesthetics but also increases the risk of wall damage and causes great trouble for subsequent maintenance. These problems highlight the limitations of traditional access control base installation methods. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: a pre-embedded installation access control base 5 structure, including a limiting plate 1, a guide seat 2 fixedly connected to the top of the limiting plate 1, guide blocks 3 fixedly connected to both sides of the outer surface of the guide seat 2, an access control body 12 detachably connected to the top of the guide seat 2, and a limiting groove 13 adapted to the guide seat 2 at the bottom of the access control body 12.

[0026] In this embodiment, the limiting plate 1 serves as the basic bearing and positioning benchmark for the entire base 5 structure. It is pre-embedded in the wall base, providing a stable installation platform for the upper components. This pre-embedded design creates a rigid connection with the wall, solving the problem of loosening inherent in traditional surface installations. This ensures the long-term stability of the overall structure and avoids displacement caused by external impacts or base deformation. Simultaneously, its flatness provides a benchmark for the precise installation of subsequent components, reducing positioning errors caused by uneven base surfaces. The guide seat 2 is fixed to the top of the limiting plate 1, forming a matching guide structure with the limiting groove 13 at the bottom of the access control body 12. This provides a standardized alignment trajectory for the installation of the access control body 12, replacing the traditional method of relying on manual visual alignment. The initial positioning is achieved through the fitting with the limiting groove 13, achieving "instant alignment," significantly reducing the difficulty of installation, minimizing repeated adjustments, and improving construction efficiency. Guide blocks 3 are symmetrically arranged on both sides of the guide seat 2, slidingly engaging with the guide groove 14 of the access control body 12. Based on the alignment of the guide seat 2 and the limiting groove 13, these blocks further restrict the horizontal displacement and angular tilt of the access control body 12, forming a "two-way guide." The constraint ensures the horizontal and vertical alignment of the access control body 12 during installation, solving the angle deviation problem that is prone to occur in traditional manual positioning. The access control body 12 is the core functional component of the access control system. It is connected to the guide seat 2 through the bottom limiting groove 13. Relying on the precise positioning and stable fixation of the base 5 structure below, it ensures the verticality and horizontality during use, avoiding recognition errors or operational inconvenience caused by installation tilt, and improving the efficiency of the access control system. The limiting groove 13 is opened at the bottom of the access control body 12 and is adapted to the shape of the guide seat 2, forming a "concave-convex fit" with the guide seat 2, providing the axial guide trajectory for the access control body 12 during installation, and realizing rapid docking.

[0027] In the above embodiment, as a preferred solution, multiple fixing bolts 4 are threaded through the inner wall of the guide seat 2 at the top of the limiting plate 1. One end of the fixing bolt 4 protruding from the limiting plate 1 is threadedly connected to the base 5. By the fixing bolt 4 passing through the limiting plate 1 and being threadedly connected to the base 5, the limiting plate 1 and the base 5 can be detachably fixed. The threaded connection ensures that the two are rigidly fixed. At the same time, the detachable design facilitates later maintenance and avoids the problem of excessive overall replacement cost caused by traditional welding or one-time fixing. In addition, it disperses the stress points and prevents single-point bolt overload and stripping. The base 5 is located between the limiting plate 1 and the cement pile 6, serving as an intermediate load-bearing structure, connecting the limiting plate 1 and the base fixing component, distributing the weight of the upper access control body 12 to the lower pre-embedded structure, and avoiding deformation caused by excessive local stress on the limiting plate 1. At the same time, it provides an installation benchmark for the cement pile 6, ensuring that the stress of multiple cement piles 6 is uniform.

[0028] In the above embodiment, as a preferred solution, multiple cement piles 6 are inserted and fixed to the top of the base 5. A screw 7 is pre-embedded and fixed to the top of the cement pile 6. The cement pile 6 is inserted and fixed to the top of the base 5 and pre-embedded inside the wall base. The screw 7 is connected to the top. By utilizing the interlocking property of cement material with the wall base, the connection strength between the base 5 and the wall is greatly improved, solving the problem of loosening caused by the softness of the wall due to traditional surface bolt fixing. This ensures that the base 5 will not sink or shift during long-term use. The screw 7 is pre-embedded in the top of the cement pile 6, passes through the positioning plate 8 and is fixed by the limiting bolt 9, providing a rigid fixing point for the positioning plate 8. At the same time, the height of the positioning plate 8 can be finely adjusted through the threaded structure to adapt to different wall thicknesses or wiring layout requirements and improve installation flexibility.

[0029] In the above embodiment, as a preferred solution, a positioning plate 8 is sleeved on the outer surface of the screw 7. One end of the screw 7 that protrudes from the positioning plate 8 is threadedly connected to a limiting bolt 9. The positioning plate 8 is sleeved on the screw 7, and the outer surface is connected to a wiring fixing component, which serves as a carrier for wiring organization. Together with the wire clamp 10, it achieves centralized fixing of the access control wiring, avoiding messy and tangled wiring. At the same time, the fixing by the screw 7 and the limiting bolt 9 ensures the stability of the wiring position and prevents the access control interface from loosening due to wiring pulling. The limiting bolt 9 is threadedly connected to the end of the screw 7 that protrudes from the positioning plate 8, pressing the positioning plate 8 and locking its position to prevent it from shifting due to vibration or external force during long-term use, ensuring the stability of the wiring fixation. The detachable design facilitates adjustment of the position of the positioning plate 8 during later wiring maintenance.

[0030] In the above embodiments, as a preferred solution, multiple wire clamps 10 are fixedly connected to the outer surface of the positioning plate 8, and multiple wire slots 11 are provided on the top of the base 5. The wire clamps 10 are fixed to the outer surface of the positioning plate 8 to hold the power cords, signal lines, etc. of the access control system, and fix the lines in an orderly manner. This avoids wear and breakage caused by the random dragging of lines in traditional installations. At the same time, it facilitates quick identification of lines during later maintenance and reduces maintenance difficulty. The wire slots 11 are opened on the top of the base 5 to allow the access control lines to pass through, providing a dedicated channel for the lines and preventing the lines from being squeezed and damaged by the base 5 or other components. At the same time, it hides the lines, improves the neatness after installation, and reduces the corrosion of the lines by the external environment.

[0031] In the above embodiment, as a preferred solution, guide grooves 14 adapted to guide blocks 3 are provided on both sides of the inner sidewall of the limiting groove 13. The inner wall of the guide groove 14 is slidably connected to the outer surface of the guide block 3. By opening the guide groove 14 on the inner sidewall of the limiting groove 13 and slidingly engaging with the guide block 3, a "secondary guiding constraint" is formed with the guide block 3. Based on the docking of the limiting groove 13 and the guide seat 2, the lateral offset and rotation of the access control body 12 are further restricted, ensuring that the trajectory is unique during installation, avoiding positioning errors caused by human operation deviations, and improving installation accuracy.

[0032] In the above embodiment, as a preferred solution, a protective plate 15 is bolted to the outer wall of the access control body 12, located outside the limiting groove 13. The protective plate 15 is bolted to the outer wall of the access control body 12, covering the connection between the limiting groove 13 and the guide seat 2, physically isolating external dust, rainwater, and impurities from entering the connection gap, preventing the guide structure from rusting or jamming; at the same time, it covers the connecting parts such as bolts, improving the overall aesthetics, and the internal guide structure can be quickly inspected by disassembling the protective plate 15, taking into account both protection and maintenance convenience.

[0033] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0034] In this invention, the working steps of the device are as follows:

[0035] During the construction of the wall base, cement pile 6 is pre-inserted and fixed in the designed position to ensure that cement pile 6 is vertically embedded in the wall base and that the top of screw 7 protrudes from the wall surface.

[0036] After the wall base has cured, align the base 5 with the insertion position at the top of the cement pile 6 and press down to make the base 5 and the cement pile 6 tightly connected; then, attach the positioning plate 8 to the screw 7, adjust the height of the positioning plate 8 to the position that matches the wiring layout, tighten the limit bolt 9 to fix the positioning plate 8, and pass the power line, signal line, etc. of the access control system through the wiring groove 11 of the base 5, and fix the wiring in an orderly manner through the wire clamp 10 of the positioning plate 8 to avoid messy wiring or being pulled by force.

[0037] Place the limiting plate 1 above the base 5, aligning the bolt holes on the limiting plate 1 with the base 5. Insert the fixing bolts 4 and tighten them to ensure a rigid connection between the limiting plate 1 and the base 5.

[0038] Align the limiting groove 13 at the bottom of the access control body 12 with the guide seat 2 on the limiting plate 1, so that the guide blocks 3 on both sides of the guide seat 2 are embedded in the guide groove 14 of the access control body 12, and slide the access control body 12 down along the guide trajectory until the bottom of the access control body 12 is in contact with the top of the limiting plate 1.

[0039] On the outer side of the corresponding limiting groove 13 on the outer wall of the access control body 12, the protective plate 15 is fixed by bolts so that the protective plate 15 completely covers the connection part between the guide seat 2 and the limiting groove 13. The protective plate 15 isolates external dust, rainwater and other impurities, preventing the guide structure from rusting or getting stuck; at the same time, it covers the connection gaps and improves the overall aesthetics.
