Description

Technical Field

[0001] The utility model relates to the technical field of pressure testing mechanisms, in particular to a pressure testing mechanism for fire sprinklers. Background Art

[0002] Fire sprinklers are an indispensable part of the fire protection system. When a fire occurs, the medium in the glass will reach a certain temperature, causing the glass to rupture. Firefighting water will then be sprayed out through the sprinkler head splash plate to extinguish the fire. In order to ensure the safety of the fire protection system, fire sprinklers need to be inspected before leaving the factory.

[0003] When conducting random inspections on fire sprinklers, there are more inspection items, which are not as good as pressure inspection. The current common pressure inspection devices need to inspect multiple fire sprinklers at the same time when inspecting fire sprinklers. At this time, multiple fire sprinklers need to be installed on the pressure inspection device. The fire sprinklers and the pressure inspection device are mostly connected by threads. The fire sprinklers need to be rotated multiple times during installation. Since multiple fire sprinklers need to be installed during measurement, the installation time is also long, which is time-consuming and labor-intensive. For this reason, we propose a pressure testing mechanism for fire sprinklers to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Refer to Figure 1-7 , a pressure testing mechanism for a fire sprinkler, comprising a pressure test box 1 and a plurality of fire sprinklers 2, ( Figure 1The middle fire sprinkler is omitted from the drawing. In fact, each installation position on the pressure test device has an installation. A fixing structure 3 is provided on the pressure test box 1. The fixing structure 3 includes an auxiliary component 4. An extrusion component 5 and a fixing component 6 are provided on the auxiliary component 4. The auxiliary component 4 includes an auxiliary assembly 401 and two positioning assemblies 402. The two positioning assemblies 402 correspond to the L-shaped fixing plate 4011 and the U-shaped fixing plate 4012 respectively. The extrusion component 5 includes a lifting assembly 501. The lifting assembly 501 includes a motor, a worm, a worm gear, a lead screw and a guide rod. Among them, the lead screw and the guide rod are respectively threadedly connected and slidably connected to a connecting rod 5022. The lifting assembly 501 is a prior art. An extrusion assembly 502 is provided on the lifting assembly 501. The two ends of the extrusion assembly 502 respectively correspond to a positioning assembly 402 and one end of the fixing component 6.

[0031] The auxiliary assembly 401 includes an L-shaped fixing plate 4011 and a U-shaped fixing plate 4012 fixedly connected to the pressure test box 1. The L-shaped fixing plate 4011 and the U-shaped fixing plate 4012 are respectively located on opposite sides of the pressure test box 1. The other side of the U-shaped fixing plate 4012 can limit one end of the first pressing plate 601 and the second pressing plate 602. A plurality of positioning holes 4013 are provided on one side of both the L-shaped fixing plate 4011 and the U-shaped fixing plate 4012.

[0032] The positioning assembly 402 includes a plurality of positioning rods 4021. The plurality of positioning rods 4021 are arranged at equal intervals. Two groups of positioning rods 4021 are respectively fixedly connected to the L-shaped fixing plate 4011 and the U-shaped fixing plate 4012. A support plate 4022 is slidably connected to the positioning rods 4021. Springs 4023 are sleeved on the outer surfaces of the positioning rods 4021 located on both sides among the plurality of positioning rods 4021. The two ends of the springs 4023 are respectively fixedly connected to the support plate 4022 and the L-shaped fixing plate 4011 or the U-shaped fixing plate 4012.

[0033] The extrusion assembly 502 includes two U-shaped pressing plates 5021. The two U-shaped pressing plates 5021 respectively correspond to the L-shaped fixing plate 4011 and the U-shaped fixing plate 4012. The two U-shaped pressing plates 5021 are respectively located directly above the two ends of the first pressing plate 601 and the second pressing plate 602. The two U-shaped pressing plates 5021 are fixedly connected by two connecting rods 5022.

[0034] The fixing component 6 includes a plurality of first pressing plates 601 and two second pressing plates 602. The two second pressing plates 602 are located between the two first pressing plates 601. Both ends of the first pressing plates 601 and the second pressing plates 602 pass through the positioning holes 4013 and extend out a part. Both ends of the first pressing plates 601 and the second pressing plates 602 are provided with jacks 603. The jacks 603 correspond to the positioning rods 4021.

[0035] During use, first insert the fire sprinkler 2 into the installation location of the pressure test box 1 in sequence. Subsequently, insert two first pressing plates 601 and multiple second pressing plates 602 into the L-shaped fixing plate 4011 and the U-shaped fixing plate 4012 in sequence. When inserting, align one end of the first pressing plate 601 or the second pressing plate 602 with the positioning hole 4013 and insert it. When inserting, one end will abut against one side of the U-shaped fixing plate 4012, and the first pressing plate 601 or the second pressing plate 602 will just fall on the support plate 4022.

[0036] After all the first pressing plates 601 and the second pressing plates 602 are inserted, control the motor in the lifting assembly 501 to rotate, so that the connecting rod 5022 connected to it moves downward. When the connecting rod 5022 moves downward, it will drive the U-shaped pressing plate 5021 to move downward together. When the U-shaped pressing plate 5021 moves downward, it will push the first pressing plate 601 and the second pressing plate 602 downward together. During the movement of the first pressing plate 601 and the second pressing plate 602, the support plate 4022 will be pushed downward to compress the spring 4023 until the first pressing plate 601 and the second pressing plate 602 press on the fire sprinkler 2, thereby squeezing and fixing it. At the same time, during the downward movement of the first pressing plate 601 and the second pressing plate 602, they will encounter the positioning rod 4021. Since the positioning rod 4023 corresponds to the jack 603, the positioning rod 4021 will be inserted into the jack 603, thereby limiting the first pressing plate 601 and the second pressing plate 602.
