Description

Technical Field

[0001] This utility model relates to the field of fixed bases, and more specifically, to a fixed base for a signal isolator. Background Technology

[0002] An isolator is a device that uses linear optocoupler isolation to convert input signals to output signals, isolating the input, output, and power supply from each other. It is particularly suitable for use with equipment and instruments requiring electrical isolation. Also known as a signal isolator, it is an important component of industrial control systems. Signal isolators are typically directly clipped onto the outer circumference of a guide rail, and due to the long length of the guide rail, multiple signal isolators can be mounted on a single rail.

[0003] A search revealed that Chinese patent CN222424348U discloses a "Quick-Connect Signal Isolator," which includes a base. The signal isolator body is inserted into the top surface of the base, and a groove for connection is formed on the bottom surface of the base. An adjustment groove is formed on the inner circumferential surface of the groove, and an adjustment slide block is slidably mounted inside the groove. When installing the signal isolator, the signal isolator body can be easily inserted into the top of the base, allowing the slide block to move the slider within the groove. Simultaneously, the slider easily moves the inclined block closer to the inclined plate on the inner wall surface of the groove, facilitating adjustment of the distance between the inclined block and the inclined plate. The base can then be snapped onto the outer circumference of a guide rail, facilitating the installation of the signal isolator. It can be installed on guide rails of different specifications. However, the following drawbacks still exist:

[0004] (1) The existing fixed base is an integral structure, while the signal isolator has various models and sizes. When installing different models of signal isolators, it is necessary to prepare a base of the corresponding size separately, which reduces the universality of the fixed base.

[0005] (2) The existing fixed base is fitted with the slide rail through the groove on the back of the signal isolator and then reinforced with bolts. However, the installation box of the signal isolator is small, and the bolts need to be turned individually when installing multiple signal isolators, which affects the ease of installation.

[0006] Therefore, we have made improvements to this by proposing a signal isolator mounting base. Utility Model Content

[0007] The purpose of this utility model is to address the issue that existing fixed bases are of an integral structure, while signal isolators come in various models and sizes. When installing different models of signal isolators, it is necessary to prepare a base of the corresponding size separately, which reduces the versatility of the fixed base. Furthermore, existing fixed bases use grooves on the back of the signal isolator to fit into the slide rails and are then reinforced with bolts. However, the installation box for signal isolators is small, and when installing multiple sets of signal isolators, the bolts need to be turned individually, which affects the ease of installation.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A signal isolator mounting base is provided to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] Includes a base plate, with clamping assemblies on the upper and lower sides of the base plate, a signal isolator body clamped on the front side of the clamping assemblies, a snap groove that cooperates with the clamping assemblies on the rear side of the signal isolator body, and reinforcing assemblies on the upper and lower sides of the front end of the clamping assemblies;

[0012] The clamping assembly includes a central groove opened in the center of the base plate, and a first bevel gear is provided on the inner wall of the right end of the central groove. A knob is connected to the right end of the first bevel gear.

[0013] The reinforcement component includes grooves opened on the front surfaces of the upper and lower sides of the clamping component, a plate is movably disposed inside the groove, and a pressure plate is fitted on the front surface of the plate.

[0014] As a preferred technical solution of this utility model, the inner walls of the upper and lower sides of the central groove are provided with a second conical gear that cooperates with the first conical gear.

[0015] As a preferred technical solution of this utility model, the upper and lower ends of the central groove are provided with telescopic grooves, the telescopic grooves are provided with screws, and the outer wall of the screws is fitted with telescopic plates.

[0016] As a preferred technical solution of this utility model, the side wall of the telescopic groove is provided with a side groove, and the side wall of the telescopic plate is provided with a side plate that cooperates with the side groove.

[0017] As a preferred technical solution of this utility model, a connecting plate is installed on the outer wall of the telescopic plate away from the central groove, and a clamping plate is installed on the outer wall of the front end of the connecting plate.

[0018] As a preferred technical solution of this utility model, the side wall of the groove is provided with a limiting groove, and the side wall of the panel is provided with a limiting plate that cooperates with the limiting groove.

[0019] As a preferred technical solution of this utility model, the side wall of the limiting plate is provided with a telescopic rod, and a spring is fitted on the outer wall of the telescopic rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. By setting up a first bevel gear, a second bevel gear, a screw, a telescopic plate, a side plate, and a clamping plate, when it is necessary to fix the signal isolator body of different models and sizes, turning the knob drives the first bevel gear connected to it to rotate, which in turn drives the second bevel gears on the upper and lower sides to rotate, which drives the screw connected to the outer end to rotate. Through the engagement of the outer wall thread, the telescopic plate slides in the telescopic groove. With the side plate embedded in the side groove, the distance between the upper and lower connecting plates is stably adjusted, thereby adjusting the distance between the upper and lower clamping plates according to the distance of the buckle groove on the rear side of the signal isolator body, so that the clamping plate can be snapped into the buckle groove with different spacing sizes, completing the quick clamping and installation of different signal isolator bodies, and improving the versatility of the fixing base.

[0023] 2. By setting up a panel, pressure plate, limiting plate, telescopic rod, and spring, when the clamping plate is fastened and fixed to the signal isolator body from the inside out, the pressure plate is pulled upwards, causing the panel to slide away from the signal isolator body within the groove. This causes the limiting plate to slide within the limiting groove, compressing the telescopic rod and spring, causing them to contract. After the signal isolator body is clamped and fixed outwards by the clamping plate, the pressure plate at the corresponding position is released. The telescopic rod and spring push the limiting plate, causing the panel to slide towards the signal isolator body. This, in turn, causes the pressure plate to slide towards the signal isolator body, pressing down and reinforcing it, thus improving the installation stability of the signal isolator body by the fixing base.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a signal isolator fixing base, including a base plate 1, with clamping components on the upper and lower sides of the base plate 1, a signal isolator body 3 clamped on the front side of the clamping components, a buckle groove 4 that cooperates with the clamping components on the rear side of the signal isolator body 3, and reinforcement components on the upper and lower sides of the front end of the clamping components.

[0036] The clamping assembly includes a central groove 201 opened in the center of the base plate 1, a first bevel gear 202 provided on the inner wall of the right end of the central groove 201, and a knob 203 connected to the right end of the first bevel gear 202.

[0037] The reinforcement component includes grooves 501 on the front surfaces of the upper and lower sides of the clamping component. A plate 502 is movably disposed inside the groove 501, and a pressure plate 503 is disposed on the front surface of the plate 502.

[0038] like Figure 3 As shown, the inner walls of the upper and lower sides of the central groove 201 are provided with second bevel gears 204 that cooperate with the first bevel gear 202. When it is necessary to fix the signal isolator body of different models and sizes, the knob 203 is turned to drive the first bevel gear 202 connected to it to rotate, and the meshing drives the second bevel gears 204 on the upper and lower sides to rotate.

[0039] like Figure 3 As shown, the upper and lower ends of the central groove 201 are provided with telescopic grooves 205. A screw 206 is provided inside the telescopic groove 205. A telescopic plate 207 is fitted on the outer wall of the screw 206. When the screw 206 rotates, the telescopic plate 207 is driven to slide in the telescopic groove 205 through the thread engagement of the outer wall. With the side plate 209 embedded in the side groove 208, the distance between the upper and lower connecting plates 210 is stably adjusted.

[0040] like Figure 3 As shown, the side wall of the telescopic groove 205 is provided with a side groove 208, and the side wall of the telescopic plate 207 is provided with a side plate 209 that cooperates with the side groove 208. With the side plate 209 embedded in the side groove 208, the distance between the upper and lower connecting plates 210 can be stably adjusted, thereby adjusting the distance between the upper and lower clamping plates 211 according to the distance of the latching groove 4 on the rear side of the signal isolator body 3, so that the clamping plates 211 can be fitted into the latching grooves 4 with different spacing sizes.

[0041] like Figure 4 As shown, a connecting plate 210 is installed on the outer wall of the telescopic plate 207 away from the central groove 201. A clamping plate 211 is installed on the outer wall of the front end of the connecting plate 210. By adjusting the distance between the upper and lower connecting plates 210, the distance between the upper and lower clamping plates 211 can be adjusted according to the distance of the latching groove 4 on the rear side of the signal isolator body 3, so that the clamping plate 211 can be snapped into the latching groove 4 with different spacing sizes, thus completing the quick clamping and installation of different signal isolator bodies 3.

[0042] like Figure 4 As shown, a limiting groove 504 is provided on the side wall of the groove 501, and a limiting plate 505 is provided on the side wall of the plate 502 to cooperate with the limiting groove 504. The limiting plate 505 slides in the limiting groove 504 and compresses the telescopic rod 506 and the spring 507 to make them contract.

[0043] like Figure 4As shown, a telescopic rod 506 is provided on the side wall of the limiting plate 505. A spring 507 is fitted on the outer wall of the telescopic rod 506. The telescopic rod 506 and the spring 507 are compressed to retract. When the signal isolator body 3 is clamped and fixed outward by the clamping plate 211, the pressure plate 503 at the corresponding position is released. The telescopic rod 506 and the spring 507 push the limiting plate 505, causing the insert plate 502 to slide towards the signal isolator body 3. This causes the pressure plate 503 to slide towards the signal isolator body 3 to press down and reinforce it.

[0044] Specifically, when using this fixing base: when it is necessary to fix signal isolators of different models and sizes, turning the knob 203 drives the first bevel gear 202 connected to it to rotate, which in turn drives the second bevel gears 204 on both the upper and lower sides to rotate, which in turn drives the screw 206 connected to the outer end to rotate. Through the engagement of the outer wall thread, the telescopic plate 207 slides in the telescopic groove 205. With the side plate 209 embedded in the side groove 208, the distance between the upper and lower connecting plates 210 is stably adjusted. Thus, according to the distance of the latching groove 4 on the rear side of the signal isolator body 3, the distance between the upper and lower clamping plates 211 is adjusted accordingly, so that the clamping plates 211 can be snapped into the latching grooves 4 with different spacing sizes, completing the quick clamping and installation of different signal isolator bodies 3, improving the fixing base's performance. The signal isolator body 3 is versatile. When the clamping plate 211 is fastened and fixed to the slot 4 of the signal isolator body 3 from the inside out, the pressure plate 503 is pulled upward, causing the insert plate 502 to slide away from the signal isolator body 3 in the slot 501. This causes the limiting plate 505 to slide in the limiting groove 504, compressing the telescopic rod 506 and the spring 507 to retract. After the signal isolator body 3 is clamped and fixed outward by the clamping plate 211, the pressure plate 503 at the corresponding position is released. The telescopic rod 506 and the spring 507 push the limiting plate 505, causing the insert plate 502 to slide towards the signal isolator body 3. This causes the pressure plate 503 to slide towards the signal isolator body 3 to press down and reinforce it, improving the installation stability of the fixed base for the signal isolator body 3.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
