Description

Technical Field

[0001] The present invention relates to the technical field of fire terminal testing, and more specifically, to an installation structure for fire terminal vibration testing and a fire terminal vibration testing device. Background Art

[0002] Fire terminal products such as point-type smoke detectors, point-type heat detectors and manual fire alarm buttons of different standards need to undergo vibration sinusoidal operation tests and vibration sinusoidal endurance tests before leaving the factory. The conventional test method is: install and fix the sample by ceiling or wall mounting, so that the sample is in a normal monitoring state; then, in turn, in three mutually perpendicular axis directions, within the frequency cycle range of 10Hz to 150Hz, at a speed of 4.905m / s 2 The acceleration amplitude is 100° and the sweep rate is 1 oct / min. One sweep cycle is performed for each test. Then the working status of the sample is observed and recorded, such as checking the appearance of the sample and the fastening parts.

[0003] In the prior art, the method of installing and fixing the fire terminal is usually: fix the fire terminal sample to be tested on a flat plate with the front side facing up, and then tie the flat plate to the table top of the vibration table with a rope. Although this structure is simple, tying the rope is time-consuming and laborious. Because the length of the rope is inconsistent with the size of the flat plate on which the sample is installed, there is often an extra small section of rope that cannot be well knotted or fixed, resulting in the overall looseness and poor test effect. Sometimes, due to the different strength of the operators, the tightness of the binding rope is different, which also causes the overall looseness and poor test effect. Moreover, this method cannot put the fire terminal sample to be tested in a normal monitoring state of ceiling or wall hanging, making the test result inaccurate. In subsequent improvement plans, two vertical and spaced-apart screws are generally set on the table top of the vibration table, with an iron block strip connected between the two screws for lifting and lowering. When a flat plate is placed on the table top of the vibration table and located between the two screws, the fire terminal sample under test on the flat plate can be pressed down by the iron block strip. Although the stability is increased, the fasteners on the iron block strip must be adjusted when moving and fixing it, which is time-consuming and labor-intensive, and the ease of operation needs to be improved.

Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0029] Embodiment 1: The embodiment of the present invention provides a fire terminal vibration test installation structure, such as Figures 1 to 5 As shown in the figure, the installation structure for vibration testing of the fire terminal includes a support plate body 1 and a U-shaped installation plate body 2; the support plate body 1 is provided with a plurality of first positioning slots 101 spaced apart longitudinally and parallel to each other and a plurality of second positioning slots 102 spaced apart transversely and parallel to each other, and each second positioning slot 102 is cross-perpendicular to each first positioning slot 101; the opening end of the U-shaped installation plate body 2 faces downward, and the bottoms of the two opposite side plates 22 of the U-shaped installation plate body 2 are correspondingly tightly fitted and inserted into any two first positioning slots 101 or any two second positioning slots 102; at least one of the top plate 21 and the two opposite side plates 22 of the U-shaped installation plate body 2 is provided with a fire terminal installation position.

[0030] For example, in this embodiment, the upper surface of the support plate body 1 is provided with two first positioning slots 101 which are spaced apart longitudinally and parallel to each other, and two second positioning slots 102 which are spaced apart transversely and parallel to each other, and the two first positioning slots 101 are cross-distributed with the two second positioning slots 102. The U-shaped mounting plate body 2 is composed of a top plate 21 and two side plates 22 which are integrally connected to two opposite sides of the top plate 21, and the bottoms of the two opposite side plates 22 of the U-shaped mounting plate body 2 can be inserted into the two first positioning slots 101 or the two second positioning slots 102 in a correspondingly tight fit. When the bottoms of the two opposite side plates 22 of the U-shaped mounting plate body 2 are correspondingly tightly fitted and inserted into the two first positioning slots 101, during the vibration test, the support plate is vibrated in the lateral direction (X-axis) to drive the U-shaped mounting plate body 2 to vibrate in a direction perpendicular to the first positioning slots 101 (i.e., parallel to the second positioning slots 102), so that the U-shaped mounting plate body 2 vibrates in the lateral direction (X-axis); conversely, the U-shaped mounting plate body 2 is rotated 90° laterally so that the bottoms of the two opposite side plates 22 of the U-shaped mounting plate body 2 are correspondingly tightly fitted and inserted into the two If the second positioning slot 102 is in the vibration test, the support plate is vibrated in the longitudinal direction (Y axis) to drive the U-shaped mounting plate 2 to vibrate in the direction perpendicular to the second positioning slot 102 (i.e. parallel to the first positioning slot 101), so that the U-shaped mounting plate 2 vibrates in the longitudinal direction (Y axis); when the U-shaped mounting plate 2 needs to vibrate in the vertical direction (Z axis), it is not affected by the first positioning slot 101 and the second positioning slot 102, and the support plate is vibrated up and down to drive the U-shaped mounting plate 2 to vibrate up and down. Thus, when a fire terminal is installed on the fire terminal installation position of the top plate 21 and / or any side plate 22 of the U-shaped mounting plate 2, a vibration test of the fire terminal can be achieved, the installation stability is good, and the vibration test of the fire terminal under the normal monitoring state of the ceiling and / or wall hanging is satisfied.

[0031] Specifically, in the present embodiment, the support plate body 1 is also connected to two U-shaped limit rods 3; when the bottoms of the two opposite side plates 22 of the U-shaped mounting plate body 2 are correspondingly tightly fitted and inserted in the two first positioning slots 101, the two U-shaped limit rods 3 are correspondingly located on the outsides of the two opposite side plates 22 of the U-shaped mounting plate body 2; the open end of each U-shaped limit rod 3 faces downward, and the bottoms of the two opposite side rods of each U-shaped limit rod 3 are correspondingly tightly fitted and inserted in the two second positioning slots 102, and are tightly abutted against the bottoms of the side plates 22 of the corresponding U-shaped mounting plate body 2, thereby playing a role in limiting the U-shaped mounting plate body 2, so as to further keep the U-shaped mounting plate body 2 stable on the support plate body 1. It can be understood that when the bottoms of the two opposite side plates 22 of the U-shaped mounting plate body 2 are tightly fitted and inserted in the two second positioning slots 102, the two U-shaped limit rods 3 are also correspondingly located on the outside of the two opposite side plates 22 of the U-shaped mounting plate body 2; the open end of each U-shaped limit rod 3 is also facing downward, and the bottoms of the two opposite side rods of each U-shaped limit rod 3 are tightly fitted and inserted in the two first positioning slots 101, and are tightly pressed against the bottom of the corresponding side plate 22 of the U-shaped mounting plate body 2.

[0032] Furthermore, in the present embodiment, the bottoms of the two opposite side plates 22 of the U-shaped mounting plate body 2 are provided with corresponding positioning strips 23 matched with the two first positioning slots 101; the bottoms of the two opposite side rods of each U-shaped limiting rod 3 are provided with corresponding positioning blocks 31 matched and snapped into the two second positioning slots 102; the shape and size of each second positioning slot 102 are consistent with the shape and size of the first positioning slot 101, then the positioning strip 23 is also matched with the second positioning slot 102, and the positioning block 31 can also be matched and snapped into the first positioning slot 101, so as to realize the installation and fixation of the U-shaped mounting plate body 2 in the longitudinal / lateral direction. Among them, the lower surface of each positioning card strip 23 is provided with a plurality of protrusions 230, and the plurality of protrusions 230 are arranged one by one and distributed at intervals; the inner bottom surface of each first positioning card slot 101 is provided with a plurality of recesses 103, and the plurality of recesses 103 are arranged one by one and distributed at intervals; when the U-shaped mounting plate body 2 is inserted into the corresponding first positioning card slot 101 through the positioning card strip 23, the plurality of protrusions 230 are correspondingly inserted into the plurality of recesses 103, so as to further keep the U-shaped mounting plate body 2 stable in the longitudinal direction on the supporting plate body 1. It should be noted that the inner bottom surface of each second positioning card slot 102 is also provided with a plurality of recesses 103, and the plurality of recesses 103 are also arranged one by one and distributed at intervals, and the lower surface of each positioning card block 31 is also provided with at least one protrusion 230, so as to fit into the corresponding recess 103 to realize the positioning of the U-shaped limit rod 3. When the U-shaped mounting plate 2 is inserted into the corresponding second positioning slot 102 through the positioning strip 23, the multiple protrusions 230 are also correspondingly inserted into the multiple recesses 103 on the inner bottom surface of the second positioning slot 102, so that the U-shaped mounting plate 2 can remain stable in the lateral direction on the support plate 1.

[0033] Furthermore, in this embodiment, the side surfaces of each positioning block 31 and any positioning strip 23 opposite to each other are inclined surfaces that can fit together. A limiting pin 41 is provided on the side surface of each positioning block 31 facing the corresponding positioning strip 23, and a limiting hole 42 for the limiting pin 41 to fit and insert is provided on the side surface of the corresponding positioning strip 23 facing the positioning block 31, so as to further limit the U-shaped mounting plate 2, thereby making the U-shaped mounting plate 2 more stable on the support plate 1. For example, the first positioning slot 101 and the second positioning slot 102 are both dovetail slots, and the positioning strip 23 and the positioning block 31 are both adapted thereto. In other embodiments, the side surfaces of each positioning block 31 and any positioning strip 23 opposite to each other are planes that can fit together.

When installing the fire terminal, it can be fastened to the first installation through hole 601 by fasteners such as screws. The setting of the two second installation through holes 602 is to facilitate the pre-positioning of the fire terminal so that the fire terminal can be installed subsequently by fasteners such as screws, making the installation operation more convenient.
