Description

Technical Field

[0001] This utility model relates to the field of sensor bracket technology, and in particular to a combined bracket. Background Technology

[0002] Currently, there are several ways to fix photoelectric switches: (1) Fixing with foam blocks, that is, digging holes in the foam, placing the sensor in the holes, and placing the foam block under the object being measured; (2) C-shaped iron brackets, with a mounting hole for installing the sensor at one end of the C-shape, and the other end placed on the ground under the object being measured; (3) Fixing with a small tripod, fixing the sensor on top of the tripod, and placing the tripod on the ground under the object being measured. However, because the fixing devices of photoelectric switches are easily moved and placed arbitrarily, the height of the sensor from the object being measured, the end face position, and the center line position are not uniform, resulting in different signals being obtained for the same object being measured at different positions, causing false alarms and malfunctions. Utility Model Content

[0003] Based on the above analysis, the present invention aims to provide a combined bracket for in-situ detection sensors to solve the problem that the relative position between the existing photoelectric switch fixing device and the object being detected is not fixed.

Detailed Implementation

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] It should be noted that pyrotechnics are a general term for disposable components and devices containing gunpowder or explosives that, upon external stimulation, will burn or explode to ignite the gunpowder, detonate the explosive, or perform mechanical work. Examples include percussion caps, primers, and ignition tubes. Related equipment or devices will have specific working positions during the assembly, testing, and experimentation of pyrotechnics; these positions are called "pyrotechnic work stations."

[0033] A specific embodiment of this utility model, combined with Figure 1 , Figure 2 and Figure 3 As shown, a combined support (i.e., a pyrotechnic station support) is disclosed, including a support base 1 and a sensor mounting plate 2. The support base 1 is connected to a pyrotechnic item parking support 100. One end of the sensor mounting plate 2 is connected to the support base 1, and the other end is connected to an in-situ sensor 200. The support base 1 includes a movable member 11, a fixed member 12, and a first fastener 13. One end of the movable member 11 is rotatably connected to one end of the fixed member 12, and the other end of the movable member 11 is connected to the other end of the fixed member 12 via the first fastener 13. The sensor mounting plate 2 is connected to the middle of the fixed member 12, and the movable member 11 and the fixed member 12 surround the connecting part (such as the crossbar 101) of the pyrotechnic item parking support 100.

[0034] Compared with the prior art, the combined bracket provided in this embodiment is connected to the pyrotechnic product parking bracket 100. One end of the sensor fixing plate 2 is used to connect to the bracket fixing plate 1, and the other end is used to install the sensor 200. The bracket fixing plate 1 includes a movable part 11 and a fixed part 12 that are rotatably connected. The sensor fixing plate 2 is connected to the middle of the fixed part 12. The movable part 11 and the fixed part 12 surround the connecting part of the pyrotechnic product parking bracket 100 and are fastened by the first fastener 13, so that the combined bracket can be stably connected to the installation part, and the relative position of the sensor 200 and the pyrotechnic product 300 can be fixed. At the same time, the movable part 11 and the fixed part 12 can be quickly installed by the first fastener 13, which is convenient to install and has a low cost.

[0035] Combination Figure 1 , Figure 4 and Figure 5 As shown, the movable part 11 includes a rotating connecting part 111, an arc-shaped part 112 and a locking part 113 connected in sequence. The rotating connecting part 111 is rotatably connected to one end of the fixed part 12. The thickness of the locking part 113 gradually decreases in the direction away from the arc-shaped part 112, forming a wedge-shaped structure. The locking part 113 is used for connection with the first fastener 13.

[0036] For connection with the first fastener 13, such as Figure 4 As shown, the locking part 113 is provided with a first slot 1131, which passes through both sides of the locking part 113 and its free end face. The first fastener 13 includes a hinge bolt 131 and a first wing nut 132. One end of the hinge bolt 131 is rotatably connected to the fixing member 12, and the other end passes through the first slot 1131 and is connected to the first wing nut 132.

[0037] Combination Figure 1 , Figure 4 and Figure 5 As shown, the fixing member 12 includes a first connecting block 121, a second connecting block 122, and a third connecting block 123 connected in sequence. A rotating connecting part 111 is rotatably connected to the first connecting block 121, a hinge bolt 131 is rotatably connected to the third connecting block 123, and the sensor fixing plate 2 is connected to the second connecting block 122. To accommodate the rotation of the rotating connecting part 111 and the hinge bolt 131, as shown... Figure 4 As shown, the end of the first connecting block 121 is provided with a second slot 1211, and the end of the third connecting block 123 is provided with a third slot 1231. A rotating shaft is provided in both the second slot 1211 and the third slot 1231. The inner surfaces of the first connecting block 121 and the third connecting block 123 are both arc-shaped surfaces, so as to surround the crossbar 101 corresponding to the inner arc surface of the arc-shaped part 112.

[0038] In order to connect the fastener 12 to the sensor mounting plate 2, combined with Figure 1 , Figure 4 and Figure 5 As shown, the combined bracket also includes a second fastener 14, which connects the sensor fixing plate 2 and the second connecting block 122. The second connecting block 122 has a flat portion 1221 on its outer side and a groove 1222 on its inner side. The second fastener 14 includes a bolt 141 and a second wing nut 142. The bolt 141 passes through the second connecting block 122 and the sensor fixing plate 2 and is connected to the second wing nut 142.

[0039] Understandably, such as Figure 4 and Figure 5 As shown, the planar portion 1221 is also provided with a first limiting hole 1223 and a second connecting hole. The second connecting hole passes through the groove 1222. There are two first limiting holes 1223, which are diagonally distributed. When connecting the sensor fixing plate 2 and the fixing member 12, the head of the bolt 141 is located in the groove 1222, and the second wing nut 142 is located outside the fixing member 12 so as to tighten the second wing nut 142. The head of the bolt 141 does not interfere with the connection of the pyrotechnics parking bracket 100.

[0040] Combination Figure 1 and Figure 6 As shown, the sensor mounting plate 2 includes a base plate 21, a side plate 22, and a reinforcing plate 23. One end of the base plate 21 is perpendicularly connected to both the side plate 22 and the reinforcing plate 23, and the reinforcing plate 23 is perpendicularly connected to the side plate 22. The other end has a non-closed slot 211. The in-situ sensor 200 is connected in the non-closed slot 211. Preferably, the non-closed slot 211 is L-shaped, and its inlet width is slightly larger than the width of the mounting part. In this embodiment, the sensor mounting plate 2 is used to mount a circular proximity switch (photoelectric sensor, position sensor, etc.). The in-situ sensor 200 is inserted into the notch of the non-closed slot 211, pushed to the appropriate position in the groove, and then locked with the locking nut provided with the in-situ sensor 200.

[0041] Combination Figure 1 and Figure 6 As shown, the side plate 22 is provided with a second limiting hole 221 and a first connecting hole 222. There are four second limiting holes 221, which are evenly distributed around the circumference of the first connecting hole 222, and two of them are directly opposite the first limiting hole 1223. The limiting screw 3 passes through the second limiting hole 221 and connects to the first limiting hole 1223. The four second limiting holes 221 ensure mirror installation without requiring a mirror part, while the diagonally arranged first limiting holes 1223 ensure that the position of the in-place sensor 200 does not change during long-term use.

[0042] The sensor mounting plate 2 can be made of metal or non-metal materials.

[0043] The combined bracket of this embodiment can be installed on a cylindrical column or beam and fixed to the cylinder with an openable bracket fixing seat 1, which can accommodate cylinders of different diameters. Loosening the first wing nut 132 on the bracket fixing seat 1 will automatically open the bracket fixing seat 1, thus ensuring quick and convenient installation and fixing of the bracket to the cylinder without the need for mechanical tools or other tools, avoiding damage to the pyrotechnics by such tools.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
