Description
Technical Field
[0001] The utility model relates to the technical field of fire alarm devices, and specifically relates to a fire alarm structure for an elevator. Background Art
[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car moves on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. Since the elevator is a vertical passage inside the building, in case of a fire, the smoke will spread rapidly, and due to the special structure of the elevator, it is easy to cause smoke accumulation, which is not convenient for rescue. Therefore, in order to ensure safety, a smoke alarm needs to be installed in the elevator to detect the fire smoke in time.
[0003] At present, most smoke alarms are directly installed on the top of the elevator, and no protective components are provided outside. Since the elevator is an important tool for people to go up and down, in order to save effort when carrying things, people mostly borrow the elevator. However, when carrying things into the elevator, it is easy to bump into the smoke alarm, causing it to be damaged, affecting the operation of the smoke alarm, and resulting in the smoke alarm being unable to alarm before the fire occurs, which poses a great potential safety hazard.
[0004] Therefore, it is necessary to carry out a protective design for the fire alarm structure. Content of the Utility Model
[0005] In order to solve the above problems, the fire alarm structure for an elevator provided by the utility model can protect the smoke alarm, avoid the smoke alarm being bumped and damaged during daily use, and affect the use.

[0025] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows. Embodiment 1
[0026] In order to improve the protection ability of the fire alarm, a telescopic conduit structure is designed, and the specific scheme is as follows:
[0027] As Figures 1-3 shown, the fire alarm structure of the elevator includes a base 1, a smoke alarm 2 is installed on the base 1, a protection structure 3 is provided on the base 1, the protection structure 3 includes a protection shell 301, the protection shell 301 is detachably connected to the bottom end of the base 1, a connection block 302 is fixedly connected to the top end of the protection shell 301, a placement groove 303 is provided at the bottom end of the base 1, a sliding groove 304 is provided at the bottom end of the base 1, the placement groove 303 and the sliding groove 304 communicate with each other, and the connection block 302 is slidably connected to the sliding groove 304.
[0028] Specifically, the lower half of the protection shell 301 has a frustum-shaped structure, and the frustum-shaped part of the protection shell 301 is a mesh structure; thus, it is convenient to filter impurities and particles in the smoke during a fire, and prevent them from directly entering the smoke alarm 2 along with the smoke, affecting the service life of the smoke alarm 2.
[0029] Specifically, a plurality of connection blocks 302 are arranged in an annular array, and the plurality of connection blocks 302 as a whole have a T-shaped structure; the placement groove 303 and the sliding groove 304 are arranged in an annular array corresponding to the connection blocks 302, the plurality of placement grooves 303 have a rectangular groove structure, and the plurality of sliding grooves 304 have a T-shaped groove structure; thus, the connection block 302 can be prevented from falling off the base 1.
[0030] Specifically, a fixed ring 305 is slidably connected inside the base 1. A spring 306 is fixedly connected between the fixed ring 305 and the base 1. The top end of the connecting block 302 abuts against the bottom end of the fixed ring 305, so as to facilitate buffering through the spring 306 when the protective shell 301 is impacted.
[0031] Specifically, a fixing plate 307 is fixedly connected to the bottom end of the fixed ring 305. An insertion block 308 is provided on one side of the connecting block 302, and a slot 309 is provided on the fixing plate 307. There are multiple fixing plates 307, and the multiple fixing plates 307 are distributed in an annular array. The insertion block 308 and the slot 309 are engaged. One end of the insertion block 308 is in an arc structure, and the slot 309 is in an overall rectangular groove structure, so as to facilitate fixing and limiting the connecting block 302.
[0032] Specifically, a fixing rod 310 is fixedly connected to the base 1. The fixing rod 310 is slidably connected to the fixed ring 305. There are multiple fixing rods 310, and the multiple fixing rods 310 are distributed in an annular array, so as to facilitate limiting the fixed ring 305 when it slides.
[0033] For the fire alarm structure of the elevator in this solution, a plurality of connecting blocks are provided at the top of the protective shell 301. Correspondingly, a placement groove is opened at the bottom end of the base 1. The connecting block 302 is inserted into the placement groove 303, and then the protective shell is rotated. The connecting block at the top end of the protective shell 301 slides inside the base through the chute 304 on the base. After the protective shell rotates a certain angle, the connecting block at the bottom end of the protective shell 301 no longer coincides with the placement groove on the base, and the connecting block 302 cannot fall off through the placement groove 303. The protective shell 301 protects the smoke detector at the bottom end of the base 1, preventing someone from bumping the smoke detector when carrying things into the elevator and affecting the operation of the smoke detector.
[0034] Instructions for use:
[0035] First, align the multiple connecting blocks 302 at the top of the protective shell 301 with the placement grooves 303 at the bottom of the base 1, and insert the connecting blocks 302 into the placement grooves 303. Then, rotate the protective shell 301. The connecting blocks 302 at the top of the protective shell 301 slide within the base 1 through the sliding grooves 304 on the base 1. Due to the T-shaped structure of the connecting blocks 302 and the sliding grooves 304, the connecting blocks 302 are prevented from falling off the base 1. After the protective shell 301 is rotated by a certain angle, the insertion blocks 308 on one side of the connecting blocks 302 are engaged with the slots 309 on the fixing plate 307 at the bottom of the fixing ring 305, fixing the connecting blocks 302 and thus fixing the protective shell 301 to prevent it from rotating. During daily use, the protective shell 301 can protect the smoke detector 2, preventing someone from directly hitting the smoke detector 2 when carrying things into the elevator and affecting its operation. Moreover, when an external object hits the protective shell 301, the connecting blocks 302 at the top of the protective shell 301 can drive the fixing ring 305 to slide upward through the fixing rod 310 and compress the spring 306, buffering the force received by the protective shell 301, reducing damage to the protective shell 301, and extending its service life. Also, during a fire, the protective net structure at the bottom of the protective shell 301 can filter impurities and particles in the flue gas, preventing the impurities and particles in the flue gas from directly adsorbing on the smoke detector 2 and affecting its service life.
