Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire detector installation technology, and in particular to a point-type heat-sensing fire detector installation device. Background Technology
[0002] Currently, point-type heat-sensitive fire detectors are installed at high points on the walls of stadiums and building lobbies to provide fire alarms within the buildings.
[0003] When fire detectors are installed, and when staff regularly inspect them, the detectors are often located at a high position. Therefore, staff need to use ladders or other climbing devices to climb up the height to inspect or install the detectors.
[0004] When using ladders and other tools inside buildings, the floor surfaces are mostly covered with smooth wooden floors or floor tiles, making the ladders prone to wobbling on the ground. This makes it difficult for staff to stand on the ladders and can also scratch the floor surfaces. Furthermore, at least one staff member is needed on the ground to hold the ladder steady, which takes up unnecessary manpower. All these factors make it inconvenient for staff to inspect and maintain the detectors. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, this utility model provides a point-type heat-sensing fire detector installation device, which can quickly and conveniently install fire detectors.
[0006] The technical solution adopted by this utility model is as follows: A point-type heat-sensing fire detector installation device includes a lower support rod, the upper end of the lower support rod is threaded to an upper support rod, the upper end of the upper support rod is threaded to a bottom shell, and a positioning seat is bolted to the upper side of the bottom shell; a support ring is bolted to the outside of the positioning seat, and two ear plates are symmetrically arranged on the outside of the support ring, with a clamping ring hinged inside the ear plates.
[0007] Furthermore, a rotating rod is provided on the lower side of the clamping ring. One end of the rotating rod is hinged to the ear plate on the outside of the support ring, and the other end of the rotating rod is slidably connected to the groove of the U-shaped plate. A pull rod is threadedly connected to the lower side of the U-shaped plate, and a locking nut is provided between the pull rod and the U-shaped plate.
[0008] Furthermore, the clamping ring is provided with multiple arc-shaped grooves and protrusions.
[0009] Furthermore, a locking ring is installed between the lower support rod and the upper support rod.
[0010] Furthermore, the upper end of the lower support rod is bolted to a baffle plate, a tie rod runs through the middle of the baffle plate, and the retaining ring at the lower end of the tie rod abuts against the lower side of the baffle plate.
[0011] Furthermore, a positioning post is set at the center of the positioning seat, and the positioning post is inserted into the center hole;
[0012] A convex ring is provided on the upper side of the positioning seat, and multiple limiting grooves are evenly distributed around the convex ring. The limiting grooves contain reinforcing bars.
[0013] Furthermore, a support ring is provided on the outer side of the positioning seat.
[0014] Compared to existing technologies, the beneficial effects achieved by adopting the above structure in this application are:
[0015] 1. The relative positioning of the positioning plate and the detector body, and the relative clamping of the clamping ring and the detector body, achieve the relative fixation of the detector body and the installation device.
[0016] 2. The relative rotation of the lower and upper support rods facilitates the clamping and loosening of the clamping ring and the detector body.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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 protection scope of the present utility model.
[0029] like Figures 1-8 As shown, this utility model provides an installation device for a point-type heat-sensing fire detector, including a lower support rod 21, with an upper support rod 22 threadedly connected to the upper end of the lower support rod 21. The upper support rod 22 and the lower support rod 21 are used to support the point-type heat-sensing fire detector 1 and bring the point-type heat-sensing fire detector 1 into contact with the roof. The upper end of the upper support rod 22 is threadedly connected to a bottom shell 23, and a positioning seat 24 is bolted to the upper side of the bottom shell 23. The positioning seat 24 is used to position the point-type heat-sensing fire detector 1 circumferentially and axially, thereby achieving relative fixation between the point-type heat-sensing fire detector 1 and the positioning seat 24.
[0030] The positioning seat 24 is bolted to the outer side of the support ring 26. Two ear plates 261 are symmetrically arranged on the outer side of the support ring 26. The ear plates 261 are hinged to the clamping ring 25. The clamping ring 25 is used to clamp and fix the point-type heat-sensing fire detector 1 to prevent the point-type heat-sensing fire detector 1 from falling off.
[0031] The point-type heat-sensing fire detector 1 includes a mounting base 11 and a detector body 12. The mounting base 11 is fixed to the roof by screws or expansion bolts, and the mounting base 11 and the detector body 12 are detachably connected by rotation.
[0032] Multiple ribs 13 are arranged circumferentially on the lower side of the detector body 12, and a central hole 14 is provided in the middle of the lower side of the detector body 12. The ribs 13 and the central hole 14 are used to make the detector body 12 contact with the outside air, so as to facilitate the sensing of temperature changes.
[0033] See Figure 6A rotating rod 251 is provided on the lower side of the clamping ring 25. One end of the rotating rod 251 is hinged to the ear plate 261 on the outer side of the support ring 26, and the other end of the rotating rod 251 is slidably connected in the groove 271 of the U-shaped plate 27. A pull rod 28 is threadedly connected to the lower side of the U-shaped plate 27. A locking nut 281 is provided between the pull rod 28 and the U-shaped plate 27. The locking nut 281 achieves a stable connection between the pull rod 28 and the U-shaped plate 27 and prevents loosening.
[0034] When the pull rod 28 moves downward, it drives the U-shaped plate 27 to move downward. The U-shaped plate 27 drives the rotating rod 251 to rotate. The rotating rod 251 drives the clamping ring 25 to approach the point-type heat-sensing fire detector and clamp and fix the point-type heat-sensing fire detector.
[0035] Multiple arc-shaped grooves and protrusions are provided on the clamping ring 25. The grooves and protrusions increase the friction between the clamping ring 25 and the point-type heat-sensing fire detector, thereby improving the connection reliability.
[0036] See Figure 5 A locking ring 211 is provided between the lower support rod 21 and the upper support rod 22. The locking ring 211 facilitates the relative fixation between the lower support rod 21 and the upper support rod 22, thereby improving the stability of operation.
[0037] The upper end of the lower support rod 21 is bolted to the retaining plate 212, and the retaining plate 212 has a pull rod 28 running through its middle. The retaining ring at the lower end of the pull rod 28 abuts against the lower side of the retaining plate 212. When the lower support rod 21 moves away from the upper support rod 22, the retaining plate 212 at the upper end of the lower support rod 21 pulls the pull rod 28 downward, and the pull rod 28 drives the U-shaped plate 27 to move.
[0038] See Figure 8 A positioning post 244 is set at the center of the positioning base 24, and the positioning post 244 is inserted into the center hole 14, which improves the convenience of installation of the point-type heat-sensing fire detector 1.
[0039] A convex ring 241 is provided on the upper side of the positioning seat 24. Multiple limiting grooves 242 are evenly distributed around the convex ring 241. The limiting grooves 242 accommodate the reinforcing strips 13, thereby fixing the point-type heat-sensing fire detector 1 and the positioning seat 24 in a circumferential manner. The positioning seat 24 drives the point-type heat-sensing fire detector 1 to rotate, thereby realizing the rotation of the point-type heat-sensing fire detector 1 and enabling the rapid installation of the point-type heat-sensing fire detector 1.
[0040] A contact ring 243 is provided on the outside of the positioning base 24. The contact ring 243 abuts against the lower side of the point-type heat-sensing fire detector 1, which facilitates the quick installation of the point-type heat-sensing fire detector 1 and the positioning base 24.
[0041] Working principle: The detector body 12 of the point-type heat-sensing fire detector 1 is placed on the upper side of the positioning seat 24. At this time, the reinforcing bar 13 is engaged in the limiting groove 242, and the positioning post 244 is inserted into the center hole 14, thus completing the relative positioning of the positioning seat 24 and the detector body 12.
[0042] Then, the lower support rod 21 is rotated. When the lower support rod 21 moves away from the upper support rod 22, the baffle 212 at the upper end of the lower support rod 21 pulls the pull rod 28 downward. The pull rod 28 drives the U-shaped plate 27 to move downward. As the U-shaped plate 27 moves downward, the rotating rod 251 rotates. The rotating rod 251 drives the clamping ring 25 to approach the detector body 12 and clamp and fix the detector body 12.
[0043] Then, rotating the locking ring 211 fixes the lower support rod 21 and the upper support rod 22.
[0044] Then lift the lower support rod 21 and the upper support rod 22, move the detector body 12 close to the mounting base 11, rotate the detector body 12, and achieve a relatively fixed installation between the detector body 12 and the mounting base 11.
[0045] Finally, rotate the lower support rod 21 in the opposite direction. The lower support rod 21 approaches the upper support rod 22. At this time, the baffle 212 no longer presses against the pull rod 28, and the clamping ring 25 no longer clamps the detector body 12. The positioning seat 24 and the detector body 12 can then be separated to complete the installation.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
