Description

Technical Field

[0001] This utility model relates to the field of smoke alarm technology, specifically a fire smoke alarm that is easy to install. Background Technology

[0002] Smoke detectors are fire detection devices that typically determine whether to issue an alarm signal by monitoring the smoke concentration in the surrounding environment, thereby eliminating fire damage in the early stages of a fire.

[0003] The utility model patent application with publication number "CN217181627U" discloses a smoke alarm for fire protection, which mainly consists of a base, a shell, a protective cover, a protective net, a shock-absorbing pad, an alarm body, and a cleaning device. This technical solution facilitates the protection and installation of the alarm body through the design of the base, the protective cover, and the protective cover itself. The cleaning device and the filter cotton design increase the cleanliness of the protective cover and the inside of the shell, making the alarm body more accurate and efficient.

[0004] The fire smoke detector disclosed in the above document has the following defects: the base of the fire smoke detector is installed on the outside of the wall by bolts. It is difficult to ensure that the base is installed firmly by means of bolts alone. When vibration occurs, the bolts may loosen, which will lead to poor fixation of the base and may cause the smoke detector to fall off and be damaged.

[0005] Therefore, it can be seen that existing fire smoke detectors lack components for stable installation, and improvements are needed to address these shortcomings in order to provide a fire smoke detector that is easy to install. Summary of the Invention

[0006] The purpose of this invention is to provide a fire smoke alarm that is easy to install, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a fire smoke alarm that is easy to install, including an alarm body, the alarm body is mounted with a housing through a connecting component, and the upper surface of the housing is provided with a mounting component.

[0009] Furthermore, the connecting assembly includes a fixing block, one end of which is provided with a connecting rod, and the end of the connecting rod away from the fixing block is provided with a pull block. The inner surface of the housing is provided with a first groove, and the outer surface of the alarm body is provided with a second groove. The first groove and the second groove cooperate to form a mounting cavity. The fixing block is installed inside the mounting cavity. The outer surface of the housing is provided with a through hole, and the connecting rod is slidably connected inside the through hole. A spring is sleeved on the outer surface of the connecting rod. One end of the spring is installed on the outer surface of the housing, and the other end of the spring is installed on the outer surface of the pull block.

[0010] Furthermore, the mounting assembly includes a mounting rod, a first connecting ring is mounted on the outer surface of the mounting rod, a connecting disc is slidably connected to the outer surface of the mounting rod, a second connecting ring is provided at one end of the connecting disc, an elastic reinforcing piece is provided between the first connecting ring and the second connecting ring, a connecting lug is provided on the outer surface of the housing, and a mounting rod is provided on the upper surface of the connecting lug.

[0011] Furthermore, the outer surface of the connecting lug is provided with a threaded hole, and the threaded hole is internally connected to a threaded segment. One end of the threaded segment is fitted with a connecting disc via a bearing, and the other end of the threaded segment is provided with a knob.

[0012] Furthermore, the outer surface of the elastic reinforcing sheet is provided with anti-slip texture.

[0013] Furthermore, a mounting groove is provided on the lower surface of the housing, and a sealing block is interference-fitted into the interior of the mounting groove. A dust cover is provided on the lower surface of the sealing block.

[0014] This utility model has the following beneficial effects:

[0015] (1) By rotating the knob, the knob drives the threaded section to rotate, which in turn pushes the connecting plate to slide. This causes the connecting plate to move along the shaft, causing the second connecting ring to move closer to the first connecting ring. At the same time, the elastic reinforcing plate between the second connecting ring and the first connecting ring is compressed and expanded, causing the outer surface of the elastic reinforcing plate to abut against the inner surface of the mounting hole, thereby increasing the stability of the mounting rod in the mounting hole and achieving a better practical effect.

[0016] (2) This utility model places the alarm body inside the housing, and then pulls the pull block outward, so that the connecting rod moves outward along the axis, so that the fixing block is installed in the first groove. At the same time, the spring is gradually stretched. Then the alarm body is rotated so that the second groove is aligned with the first groove. At this time, the force on the pull block is removed, so that the spring recovers its elasticity and pushes the fixing block to move into the second groove. When the fixing block is installed in the second groove, the fixed installation between the housing and the alarm body can be completed, so as to achieve the effect of easy installation.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model is a fire smoke alarm that is easy to install, including an alarm body 1, an outer shell 3 is installed on the alarm body 1 through a connecting component 2, and an installation component 4 is provided on the upper surface of the outer shell 3.

[0027] The connecting component 2 includes a fixing block 201, a connecting rod 202 at one end of the fixing block 201, and a pull block 203 at the end of the connecting rod 202 away from the fixing block 201. A first groove 301 is formed on the inner surface of the outer shell 3, and a second groove 101 is formed on the outer surface of the alarm body 1. The first groove 301 and the second groove 101 cooperate to form a mounting cavity. The fixing block 201 is installed inside the mounting cavity. A through hole is formed on the outer surface of the outer shell 3. The connecting rod 202 is slidably connected inside the through hole. A spring 204 is sleeved on the outer surface of the connecting rod 202. One end of the spring 204 is installed on the outer surface of the outer shell 3, and the other end of the spring 204 is installed on the outer surface of the pull block 203.

[0028] When installing the alarm body 1, the alarm body 1 is placed inside the housing 3, and then the pull block 203 is pulled outward, causing the connecting rod 202 to move outward along the axis, so that the fixing block 201 is fitted into the first groove 301. At the same time, the spring 204 is gradually stretched. Then the alarm body 1 is rotated so that the second groove 101 is aligned with the first groove 301. At this time, the force on the pull block 203 is released, so that the spring 204 regains its elasticity and pushes the fixing block 201 into the second groove 101. When the fixing block 201 is fitted into the second groove 101, the fixed installation between the housing 3 and the alarm body 1 is completed, achieving the effect of easy installation.

[0029] When it is necessary to disassemble the alarm body 1, pull the pull block 203 outward, so that the connecting rod 202 moves outward along the axis, and the fixing block 201 gradually slides from the second groove 101 into the first groove 301. When the fixing block 201 is completely disengaged from the second groove 101, the alarm body 1 can be pulled down to separate the alarm body 1 from the outer shell 3.

[0030] Mounting assembly 4 includes mounting rod 401, a first connecting ring 402 mounted on the outer surface of mounting rod 401, a connecting plate 403 slidably connected to the outer surface of mounting rod 401, a second connecting ring 404 provided at one end of connecting plate 403, an elastic reinforcing piece 405 provided between the first connecting ring 402 and the second connecting ring 404, a connecting lug 302 provided on the outer surface of housing 3, and mounting rod 401 provided on the upper surface of connecting lug 302;

[0031] The outer surface of the connecting ear block 302 is provided with a threaded hole, and the threaded hole is internally connected to a threaded section 406. One end of the threaded section 406 is mounted with a connecting plate 403 via a bearing, and the other end of the threaded section 406 is provided with a knob 407.

[0032] The outer surface of the elastic reinforcing sheet 405 is provided with anti-slip texture;

[0033] When installing the outer casing 3, a mounting hole with a diameter and length similar to that of the mounting rod 401 is drilled into the wall to be installed. Then, reinforcing adhesive is injected into the mounting hole and the mounting rod 401 is placed into the mounting hole coated with reinforcing adhesive. By rotating the knob 407, the knob 407 drives the threaded section 406 to rotate, which pushes the connecting plate 403 to slide. This causes the connecting plate 403 to drive the second connecting ring 404 to move closer to the first connecting ring 402 along the axis. At the same time, the elastic reinforcing plate 405 between the second connecting ring 404 and the first connecting ring 402 is compressed and expanded, so that the outer surface of the elastic reinforcing plate 405 abuts against the inner surface of the mounting hole, thereby increasing the stability of the mounting rod 401 in the mounting hole.

[0034] The lower surface of the outer casing 3 is provided with a mounting groove 303, and a sealing block 5 is interference-connected inside the mounting groove 303. A dust cover 501 is provided on the lower surface of the sealing block 5.

[0035] When in use, the dust cover 501 can effectively block dust falling from the wall, achieving a good dust prevention effect.
