Description

Technical Field

[0001] This utility model relates to a base, and more particularly to a simple base suitable for sensor positioning. Background Technology

[0002] In the field of sensor mounting devices, existing technologies generally suffer from poor size adaptability, insufficient sealing protection, and cumbersome assembly and disassembly. For example, Chinese patent CN221659098U discloses a mounting device for sensor processing. Its base has a mounting groove on the top to cooperate with the conveyor belt to transport the sensor. Although it can achieve basic positioning, the size of the mounting groove is fixed and cannot be adapted to sensors of different thicknesses. When changing the model, the entire base needs to be replaced, which increases the cost of use.

[0003] Furthermore, Chinese patent CN209372100U discloses a sensor fixing device that uses an adhesive plate and a probe to fix the sensor. Although the installation angle can be adjusted by the probe, the adhesive fixing method makes disassembly and maintenance difficult, and the lack of a cable sealing mechanism makes it easy for impurities to enter the sensor in humid or dusty environments, affecting long-term stability.

[0004] Therefore, existing sensor base technologies have significant limitations: their rigid structures have poor adaptability and cannot accommodate differences in thickness; the fixing methods are complex and installation is cumbersome; and their protective performance is weak, lacking a sealing mechanism for cable interfaces and storage areas.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a simple base suitable for sensor positioning, making it more valuable for industrial applications. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a simple base suitable for sensor positioning.

[0007] This utility model discloses a simple base suitable for sensor positioning, comprising a base body, wherein: the base body has a recessed storage groove, the upper periphery of the storage groove extends with a baffle, the baffle has a plurality of wiring grooves distributed thereon, the base body has a limiting component distributed above the baffle, and the periphery of the base body has a plurality of connecting mechanisms distributed thereon.

[0008] Furthermore, in the aforementioned simple base suitable for sensor positioning, the storage slot is a rectangular slot with rounded chamfers at its corners.

[0009] Furthermore, in the aforementioned simple base suitable for sensor positioning, there are transition steps distributed between the storage groove and the retaining edge, and several auxiliary grooves are distributed on the transition steps.

[0010] Furthermore, in the aforementioned simple base suitable for sensor positioning, the auxiliary slot is either a rectangular slot or an elliptical slot.

[0011] Furthermore, in the aforementioned simple base suitable for sensor positioning, the wiring groove is an elliptical groove, and a sealing gasket is embedded in the wiring groove.

[0012] Furthermore, in the aforementioned simple base suitable for sensor positioning, the limiting component is a thin film top cover, the bottom of which is sealed and bonded to the base body; or, the limiting component is a sealing adhesive layer.

[0013] Furthermore, in the aforementioned simple base suitable for sensor positioning, the connecting mechanism is an extended side wing, and the extended side wing has screw holes.

[0014] Furthermore, in the aforementioned simple base suitable for sensor positioning, a detection hole is provided on the base body.

[0015] Furthermore, in the aforementioned simple base suitable for sensor positioning, several adhesive grooves are distributed on the edge.

[0016] Furthermore, in the aforementioned simple base suitable for sensor positioning, a labeling layer is distributed on the bottom of the base body.

[0017] By means of the above solution, this utility model has at least the following advantages:

[0018] 1. The entire unit consists only of basic components such as the base body and limiting components, without complex nesting or precision fitting structures. The sensor can be initially positioned simply by placing it into the storage slot. No professional tools or complex adjustments are required during assembly; only the appropriate limiting components need to be selected according to the sensor type.

[0019] 2. The base body adopts a mature one-piece molding process. The edge guards, transition steps, extended side wings and other structures are all molded with the base body in one piece, without the need for subsequent splicing, welding and other additional processing steps. Key components such as sealing gaskets and film top covers are all conventional standard parts, without the need for customized special molds or processing equipment. The production process is short and the technology is mature. It can be quickly adapted to existing plastic molding production lines and has high manufacturing efficiency.

[0020] 3. The depth of the storage slot can be adjusted according to the thickness of the sensor. The detection hole is compatible with sensors with independent detection ends, such as infrared and laser sensors. The two limit components meet the requirements of conventional protection and high sealing respectively, and can cope with different environments such as indoor and outdoor, dry, humid and dusty. In terms of installation and adaptation, the extended side wings and screw hole design can fix the base to various installation surfaces such as equipment shell, wall, bracket and so on.

[0026] Detailed Implementation

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] like Figures 1 to 3 A simple base for positioning sensor 12 is provided, comprising a base body 1. Its unique feature is that the base body 1, as the basic load-bearing component of the entire base, is manufactured using a one-piece molding process. It is preferably made of ABS engineering plastic or nylon, materials that combine lightweight, impact resistance, and weather resistance. Simultaneously, a recessed storage groove 2 is formed on the upper surface of the base body 1 to accommodate the sensor 12 to be positioned. The depth and volume of the storage groove 2 can be adapted to the dimensions of a standard sensor 12. Considering the typical dimensions of a sensor 12, a depth of 5mm-15mm in the storage groove 2 is sufficient for storage, and can be adjusted according to the thickness of the sensor 12 to ensure that the sensor 12 does not wobble after being placed inside. Furthermore, the storage slot 2 is specifically designed as a rectangular slot, and the four corners of the rectangular slot are integrally formed with rounded chamfers. These rounded chamfers can effectively prevent stress concentration at the corners of the storage slot 2 due to long-term use or assembly operations, prevent abnormal deformation of the base body 1, and also prevent abnormal compression of the sensor 12 that is subsequently placed in.

[0029] According to a preferred embodiment of this utility model, a retaining edge 3 extends integrally along the edge of the upper periphery of the receiving groove 2, and the height of the retaining edge 3 is higher than the bottom of the receiving groove 2. During implementation, the height of the retaining edge 3 is usually 2mm-5mm higher than the depth of the receiving groove 2 to form a barrier and limit the top of the sensor 12. At the same time, a transition step 11 is integrally formed between the receiving groove 2 and the retaining edge 3. The height of the transition step 11 can be flexibly designed according to the thickness of the outer edge of the sensor 12. It is generally 1mm-3mm to ensure that the top of the sensor 12 is flush with or slightly lower than the top of the retaining edge 3 after placement, reserving space for subsequent assembly of the limiting components. Furthermore, several auxiliary grooves 5 are evenly distributed on the transition step 11. The auxiliary grooves 5 can be set as rectangular grooves or elliptical grooves according to actual assembly requirements. The pre-set claws or protrusions located below the sensor 12 can be smoothly inserted into the auxiliary grooves 5 to achieve positioning and guidance, and prevent the sensor 12 from shifting in the receiving groove 2.

[0030] Furthermore, along the circumference of the retaining edge 3, several wiring grooves 4 are distributed according to the wiring requirements of the sensor 12. Specifically, the wiring grooves 4 are elliptical grooves. Compared with rectangular grooves, elliptical grooves can better accommodate different specifications of sensor 12 connection wires, such as power wires and signal wires with diameters of 1mm-3mm, avoiding bending and damage to the connection wires due to unsuitable groove shape. At the same time, a sealing gasket is embedded in the inner wall of the wiring groove 4. The sealing gasket is preferably made of aging-resistant silicone rubber, with a thickness consistent with the thickness of the retaining edge 3, typically 2mm-4mm. In this way, after final assembly, the sealing gasket fits tightly against the outer wall of the connection wire, effectively preventing external dust, moisture, and other impurities from entering the storage groove 2 through the wiring groove 4, ensuring the long-term stable operation of the sensor 12.

[0031] In practical implementation, considering the need for subsequent assembly of the limiting components, the upper surface of the retaining edge 3 is also evenly distributed with several adhesive-containing grooves 9. The depth of the adhesive-containing grooves 9 is slightly less than the height of the retaining edge 3, preferably 0.5mm-1mm. Specifically, the adhesive-containing grooves 9 are mainly used to accommodate excess sealant, such as epoxy resin sealant, during the assembly of the limiting components and the retaining edge 3, preventing the sealant from overflowing to the outside of the retaining edge 3 and affecting its appearance, or flowing into the storage groove 2 and adhering to the sensor 12, thus ensuring the sealing and cleanliness after assembly.

[0032] Furthermore, the base body 1 is equipped with a limiting component above the retaining edge 3 to limit and fix the sensor 12 in the storage slot 2 and enhance the sealing performance of the storage slot 2. This can be implemented in two ways. The first is a thin-film top cover type limiting component, where the limiting component is a thin-film top cover. The thin-film top cover can be a silicone cover, which can deform appropriately according to the pressure difference, facilitating the sensor 12's sensing of the pressure difference. The bottom edge of the thin-film top cover is sealed to the top of the retaining edge 3 of the base body 1 using a sealant, such as silicone sealant. During bonding, it is ensured that the thin-film top cover completely covers the area enclosed by the retaining edge 3, providing stable limiting for the sensor 12 and preventing external impurities from entering the storage slot 2. This allows for compatibility with conventional differential pressure sensors 12. The second method uses a sealing adhesive layer 13 to form the limiting component. This method is suitable for scenarios with higher sealing performance requirements, such as humid or dusty environments. In practice, after the sensor 12 is placed in the storage slot 2 and adjusted into position, adhesive is evenly poured into the area enclosed by the retaining edge 3. Epoxy resin or polyurethane adhesive is preferred, as these adhesives exhibit excellent sealing and adhesion properties after curing. The adhesive level is flush with the top of the retaining edge 3, forming a sealing layer 13 after complete curing. This sealing layer not only firmly fixes the sensor 12 within the receiving groove 2 but also achieves a complete seal of the receiving groove 2, further enhancing the protective effect.

[0033] Considering the subsequent installation and fixation requirements of the base body 1, several connecting mechanisms are evenly distributed around its periphery. These connecting mechanisms include extended side wings 6, which are integrally formed with the base body 1. Their number can be adjusted according to installation requirements, typically 2-4, and they are symmetrically distributed around the base body 1 to ensure balanced force during fixation. Each extended side wing 6 has a screw hole 7, the diameter of which is designed according to commonly used fixing screw specifications. During implementation, a diameter of 3mm-5mm is preferred, suitable for M3-M5 self-tapping screws or machine screws. During installation, by inserting screws into the screw holes 7, the base body 1 can be firmly fixed to the preset mounting surface, preventing displacement of the base due to vibration or external forces and ensuring the positioning accuracy of the sensor 12.

[0034] Meanwhile, for sensors 12 with independent extended probes, this invention can also provide a probe hole 8 at the bottom of the base body 1. The shape and size of the probe hole 8 are adapted to the probe end of the sensor 12. The hole diameter is slightly larger than the probe end diameter by 0.5mm-1mm to avoid obstructing the probe signal. Simultaneously, the inner wall of the probe hole 8 can be coated with a smooth coating, such as a polytetrafluoroethylene coating, to reduce reflection or absorption interference on the probe signal and ensure the normal operation of the sensor 12. This type of structure can accommodate the subsequent installation of an infrared sensor 12 or a laser sensor 12.

[0035] Furthermore, a labeling layer 10 is provided on the bottom of the base body 1, which is made using a screen printing process. During the manufacturing process, the ink used is an environmentally friendly ink that is resistant to friction and solvents, and can withstand daily cleaning and environmental corrosion. The labeling layer 10 is printed with information such as product model, production date, and installation direction indicators (such as "upward" and "detector end facing" arrows), which facilitates operators to quickly identify product parameters during installation and maintenance, ensures the correct installation direction of the base, and avoids affecting the use of the sensor 12 due to installation errors.

[0036] The assembly steps for this simple base are as follows: First, place the sensor 12 into the storage slot 2 of the base body 1 and adjust the position of the sensor 12. If there is an independent detection end, a sensor with a detection hole 8 should be selected, and the detection end should be aligned with the detection hole 8. Second, select the limiting component according to the sealing requirements. If a thin-film top cover is selected, seal and bond it to the edge 3. If a sealing adhesive layer 13 is selected, pour adhesive into the area of ​​the edge 3 and wait for it to cure. Then, lead the sensor 12 connecting wire out through the wiring groove 4, ensuring that the sealing gasket and the connecting wire are tightly fitted. Finally, insert screws through the screw holes 7 of the extended side wing 6 to fix the base to the preset mounting surface, completing the entire assembly process.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
