Description

Technical Field

[0001] The utility model relates to the technical field of waterproof shells for alarm terminals, in particular to an alarm terminal which is easy to install, has a reinforced structure and is waterproof. Background Art

[0002] As a crucial component of security systems, alarm terminals are crucial for their structural strength, waterproof performance, and ease of installation. Prior art solutions typically use screws to secure the main body and back cover, with an internal component mounting area. However, the added sealing structure to improve waterproofing often complicates assembly, and the simple internal support structure can lead to insufficient rigidity in the area housing electronic components, posing a risk of deformation with long-term use. Furthermore, the positioning of the back cover and main body relies heavily on operator experience or simple markings, making it prone to misalignment or reverse assembly during installation, leading to seal failure or structural damage. Furthermore, existing terminals have limited angle adjustment options when mounted on a wall, making them difficult to adapt to complex on-site environments.

[0003] The main defects of the existing technology are: the direct screw locking method leads to low installation efficiency and difficulty in pre-positioning; the internal component installation area of ​​the main body lacks an effective local reinforcement structure, and the overall rigidity is insufficient; there is a lack of reliable anti-misinstallation (anti-fool) and progressive guide positioning mechanism between the main body and the back cover, which easily leads to assembly errors; and the traditional back cover mounting hole design is single, and the terminal installation angle cannot be flexibly adjusted to meet the requirements of different application scenarios.

[0004] Therefore, the inventors are in urgent need of an alarm terminal that is easy to install, has a reinforced structure and is waterproof to solve the above problems. Utility Model Content

[0005] In response to the above-mentioned defects of the existing technology, the present invention provides an alarm terminal that is easy to install, has a reinforced structure and is waterproof, aiming to solve the problems in the existing technology of low installation efficiency of the alarm terminal, insufficient rigidity of the main body structure, easy assembly dislocation and limited installation angle adjustment.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is: an alarm terminal that is easy to install, has a reinforced structure and is waterproof, comprising a terminal body and a waterproof back cover, wherein the upper rear end of the terminal body is provided with a snap-fitting protrusion, the rear end of the bottom is provided with a locking groove, and the upper and lower rear ends are respectively provided with anti-fool matching grooves; a component mounting portion with a flange structure is provided inside the terminal body, and the flange structure is connected to the inner wall of the terminal body with circumferentially evenly distributed reinforcing ribs; an outer convex upper hook structure is provided at the upper front end of the waterproof back cover, the hook portion of the outer convex upper hook structure is embedded in the inner side of the snap-fitting protrusion to form an upper pre-positioning, the bottom front end of the waterproof back cover is provided with a locking protrusion adapted to the locking groove, and the front end of the waterproof back cover is provided with a progressively inclined micro-protrusion that is interference-fitted with the anti-fool matching groove; the end surface of the waterproof back cover is provided with an upper left longitudinal long hole, a lower right longitudinal long hole, a lower left transverse long hole and an upper right transverse long hole arranged in a staggered manner, and the horizontal position of the lower left transverse long hole is higher than that of the lower right longitudinal long hole.

[0007] Based on the above, the beneficial effects of an easy-to-install, structurally reinforced and waterproof alarm terminal are to solve the problems of low installation efficiency, insufficient rigidity of the main body structure, easy assembly dislocation and limited installation angle adjustment of the alarm terminal in the prior art; mainly reflected in:

[0008] 1. This utility model uses the engagement protrusion at the rear end of the terminal body to cooperate with the protruding upper hook structure at the front end of the waterproof back cover. The hook portion of the protruding upper hook structure is embedded in the inner side of the engagement protrusion to form an upper pre-positioning, thereby achieving rapid pre-fixation of the body and the back cover. No additional tools are required to complete the initial assembly, significantly reducing the adjustment time before screw tightening.

[0009] 2. The present invention utilizes a component mounting portion with a flange structure inside the terminal body and circumferentially evenly distributed reinforcement ribs between the flange structure and the inner wall of the terminal body. The reinforcement ribs form a distributed support between the flange structure and the side wall of the terminal body. This structure achieves local reinforcement of the component mounting portion, effectively dissipates stress and suppresses deformation, thereby improving the overall compressive strength.

[0010] 3. This utility model uses the interference fit of the progressively inclined micro-bumps at the front end of the waterproof back cover and the anti-mistake matching grooves at the rear end of the terminal body. The inclined surface of the micro-bumps generates a guiding extrusion force during assembly, achieving forced correction of the relative position between the back cover and the body. Closure is completed only when the micro-bumps are fully engaged in the corresponding anti-mistake matching grooves, completely eliminating reverse or offset assembly.

[0011] 4. The utility model forms an asymmetric installation fulcrum by staggering the upper left longitudinal long hole, the lower right longitudinal long hole, the lower left horizontal long hole and the upper right horizontal long hole on the end face of the waterproof back cover, and the horizontal position of the lower left horizontal long hole is higher than the lower right longitudinal long hole, so as to realize the flexible adjustment of the horizontal inclination angle of the terminal body by selecting different long hole combinations and fixing bolts.

[0012] Furthermore, the outwardly protruding upper hook structure includes a limiting recess, and the snap-fitting protrusion is snapped into the limiting recess.

[0013] Based on the above, the beneficial effect of the limiting recess is that as a component of the convex upper hook structure, it can accommodate the snap-in protrusion, realize the mechanical interlocking of the pre-positioning state, and prevent the waterproof back cover from accidentally disengaging before the screws are tightened.

[0014] Furthermore, the slope of the progressively sloped micro-bump ranges from 15° to 30°.

[0015] Based on the above, the beneficial effect of the progressively inclined micro-bump with a slope range of 15°-30° is to provide a moderate guiding extrusion force during the assembly process - when the slope is less than 15°, the insufficient guiding force may cause the misalignment correction to fail, and when it is greater than 30°, the assembly is hindered due to excessive resistance; specifically, the slope of 15°-30° enables the inclined surface to generate sufficient lateral component force to force the alignment position when pressed into the anti-foolproof matching groove, while keeping the longitudinal propulsion force within an acceptable range for manual operation, ensuring a balance between the reliability of the anti-foolproof function and the smoothness of assembly.

[0016] Furthermore, a plurality of internally threaded cylinders are provided on the four edges around the interior of the component mounting portion, and a component protection cover is provided on the outer buckle of the flange structure. The component protection cover is provided with mounting holes corresponding to the plurality of internally threaded cylinders one by one, and the component protection cover is bolted to the internally threaded cylinders through the mounting holes.

[0017] Based on the above, the beneficial effect of the mounting hole is to achieve accurate positioning of the component protection cover and press-fitting it to the surface of the flange structure, and to form a detachable waterproof barrier by locking the bolts and the internal threaded cylinder.

[0018] Furthermore, the component protection cover is provided with a card insertion slot with a closed edge protrusion, and the inner side of the waterproof back cover is provided with waterproof cotton corresponding to the closed edge protrusion.

[0019] Based on the above, the beneficial effect of the closed edge protrusion is that it is arranged around the outer edge of the card slot, and the waterproof cotton is arranged on the inner side of the waterproof back cover at a position corresponding to the closed edge protrusion. When the back cover is closed, it is compressed by the closed edge protrusion, thereby filling the microscopic gap between the closed edge protrusion and the waterproof back cover, forming a sealed barrier to block the capillary penetration path of the liquid.

[0020] Furthermore, arc-shaped concave structures are symmetrically provided on both sides of the waterproof back cover.

[0021] Based on the above, the beneficial effect of the arc-shaped concave structure is to provide a stable handheld force application area during installation or removal, enhance the operating grip and prevent the tool from slipping, and improve the convenience and safety of terminal installation and maintenance.

[0022] In order to more clearly illustrate the above features of the present invention and the objectives to be achieved, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
