Description

Technical Field

[0001] This utility model relates to the field of magnetic induction switches, specifically a magnetic induction switch. Background Technology

[0002] The inductive switches applied to the outer wall of the cylinder are mainly magnetic switches (or cylinder reed switches, cylinder magnetic induction sensors). Their core function is to achieve precise control of the cylinder's movement by detecting the position of the magnetic ring on the cylinder piston. These switches are designed specifically for cylinders and have the characteristics of high reliability and resistance to harsh environments. They are the standard configuration for cylinder position detection in industrial automation.

[0003] Cylinders come in various types, and their outer walls usually have slots for engaging inductive switches. The inductive switch is locked in position by rotating a screw to fit against the inner wall of the cylinder slot. When the working stroke of the cylinder needs to be adjusted, the locking screw is loosened and the inductive switch is slid.

[0004] There are various models of magnetic induction switches, and different models have different appearances. This means that not all magnetic induction switches can be equipped with common cylinders. Therefore, some magnetic induction switches need to be glued to the outer wall of the cylinder. However, whether it is fixed by screws or glue, the induction switch is more complicated in the subsequent position calibration process. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a magnetic induction switch to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic induction switch, comprising an induction switch movably mounted on the top of a mounting assembly, the mounting assembly engaging with the outer wall of a cylinder, the mounting assembly comprising a first mounting bracket and a second mounting bracket, the first mounting bracket and the second mounting bracket being movably mounted, the first mounting bracket having a second fitting groove inside, the second mounting bracket having a fourth fitting groove inside, the induction switch having a first limiting block and a second limiting block on both sides, the first limiting block matching the second fitting groove of the first mounting bracket, and the second limiting block matching the fourth fitting groove of the second mounting bracket.

[0007] By adopting the above technical solution and setting up an installation component to support the inductive switch, the installation and position adjustment of the inductive switch are made more convenient and quick. The installation component includes a first mounting bracket and a second mounting bracket with adjustable length. The installation component can be engaged with cylinders of different sizes. A second fitting groove is opened on the inner side of the first mounting bracket to fit with the first limiting block of the inductive switch. A fourth fitting groove is opened in the second mounting bracket to fit with the second limiting block of the inductive switch. This allows the inductive switch to slide freely within the adjustable first and second mounting brackets to adjust its position.

[0008] The present invention is further configured such that a first fitting groove is provided on the inner side of the first mounting bracket, and the first fitting groove matches the second mounting bracket.

[0009] Preferably, by setting a first fitting groove that matches the second mounting bracket, the first mounting bracket and the second mounting bracket can be fitted together and installed movably, thereby allowing the first mounting bracket and the second mounting bracket to extend and retract to adjust their length to accommodate cylinders of different sizes.

[0010] The present invention is further configured such that clamping plates are installed at the ends of the first mounting bracket and the second mounting bracket via torsion springs. Under the reset action of the torsion springs, the first mounting bracket and the second mounting bracket are engaged with the outer wall of the cylinder by the two sets of clamping plates.

[0011] Preferably, by setting a clamping plate with a torsion spring, after the lengths of the first mounting bracket and the second mounting bracket are fixed and locked, the first mounting bracket and the second mounting bracket can be clamped and engaged with the outer wall of the cylinder by the clamping plate using the reset action of the torsion spring.

[0012] The present invention is further configured such that a fifth fitting groove is provided on both sides of the second mounting bracket, and a limiting screw is installed on both sides of the first mounting bracket. When the first mounting bracket and the second mounting bracket are fitted together, the two sets of limiting screws extend into the first fitting groove of the first mounting bracket and are placed in the fifth fitting groove of the second mounting bracket. The limiting screws are used to restrict the second mounting bracket from being pulled out of the first mounting bracket.

[0013] Preferably, by setting a limiting screw and a fifth fitting groove, the second mounting bracket is locked into the first mounting bracket and cannot be pulled out.

[0014] The present invention is further configured such that a third fitting groove is provided on the inner side of the first mounting bracket, and a fitting plate is provided on the inner side of the second mounting bracket, and the fitting plate and the third fitting groove fit together.

[0015] Preferably, by providing a third fitting groove and a fitting plate, the stability of the combination of the first mounting bracket and the second mounting bracket can be improved.

[0016] The present invention is further provided with a fixing screw on the top of the first mounting bracket, the fixing screw extending into the interior of the third fitting groove, the fixing screw being used to lock the positions of the first mounting bracket and the second mounting bracket.

[0017] Preferably, fixing screws can be used to lock the positions of the first mounting bracket and the second mounting bracket.

[0018] The present invention is further configured such that a second anti-slip area is provided on the top of the interlocking plate, and a first anti-slip area is provided on the top of the first mounting bracket.

[0019] Preferably, the anti-slip area can be used to define the position of the inductive switch.

[0020] The present invention is further configured such that a pressure plate is mounted on the side of the inductive switch by means of a torsion spring, and the pressure plate is in contact with the first anti-slip area and the second anti-slip area under the reset action of the torsion spring.

[0021] Preferably, by setting a pressure plate to fit the anti-slip area, the position of the inductive switch can be fixed.

[0022] The present invention is further configured such that both the first anti-slip area and the second anti-slip area are treated with a frosting process to improve local friction.

[0023] Preferably, by frosting the anti-slip area, the friction can be increased, thereby improving the effect of fixing the position of the sensor switch. The anti-slip area can also be made of a material with a high coefficient of friction, such as rubber.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model provides an installation component for supporting the inductive switch, making the installation and position adjustment of the inductive switch more convenient and quick. The installation component includes a first mounting bracket and a second mounting bracket with adjustable length. The installation component can be fitted with cylinders of different sizes. The first mounting bracket has a second fitting groove on its inner side to fit with the first limiting block of the inductive switch, and the second mounting bracket has a fourth fitting groove to fit with the second limiting block of the inductive switch. This allows the inductive switch to slide freely within the adjustable first and second mounting brackets to adjust its position.

[0026] 2. This utility model, by setting a first anti-slip area and a second anti-slip area within the mounting assembly, allows the sensor switch to be locked in place by a pressure plate against the anti-slip area when it slides to any position. The pressure plate is mounted on the side of the sensor switch via a torsion spring. Pressing the pressure plate raises it away from the anti-slip area, releasing the sensor switch. Similarly, when the sensor switch position is adjusted and the pressure plate is released, the pressure plate automatically presses against the anti-slip area under the action of the torsion spring, thus fixing the position of the sensor switch. This allows for quick adjustment of the sensor switch position when adjusting the stroke of the cylinder later. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Please see Figure 1 - Figure 8 A magnetic inductive switch includes an inductive switch 2, which is movably mounted on the top of a mounting assembly 1. The mounting assembly 1 is engaged with the outer wall of a cylinder. The mounting assembly 1 includes a first mounting bracket 101 and a second mounting bracket 108, which are movably mounted. The first mounting bracket 101 has a second fitting groove 103 inside, and the second mounting bracket 108 has a fourth fitting groove 111 inside. A first limiting block 3 and a second limiting block 4 are provided on both sides of the inductive switch 2. The first limiting block 3 matches the second fitting groove 103 of the first mounting bracket 101, and the second limiting block 4 matches the fourth fitting groove 111 of the second mounting bracket 108. The mounting assembly 1 is used to support the inductive switch. 2. This makes the installation and position adjustment of the inductive switch 2 more convenient and quick. The mounting component 1 includes a first mounting bracket 101 and a second mounting bracket 108 with adjustable length. The mounting component 1 can be fitted with cylinders of different sizes. The first mounting bracket 101 has a second fitting groove 103 on its inner side to fit with the first limiting block 3 of the inductive switch 2. The second mounting bracket 108 has a fourth fitting groove 111 to fit with the second limiting block 4 of the inductive switch 2. This allows the inductive switch 2 to slide freely within the adjustable first mounting bracket 101 and the second mounting bracket 108 to adjust its position. The main body of the mounting component 1 is made of non-magnetic materials, such as aluminum or copper, to reduce the influence of external factors on the magnetic induction of the inductive switch 2 during operation.

[0040] Please refer to the above embodiments for further details. Figure 5 - Figure 7 The inner side of the first mounting bracket 101 is provided with a first fitting groove 102, which matches the second mounting bracket 108. By setting the first fitting groove 102 that matches the second mounting bracket 108, the first mounting bracket 101 and the second mounting bracket 108 can be fitted and installed together, so that the length of the first mounting bracket 101 and the second mounting bracket 108 can be adjusted to adapt to cylinders of different sizes.

[0041] Please refer to the above embodiments for further details. Figure 3The ends of the first mounting bracket 101 and the second mounting bracket 108 are each fitted with a clamping plate 113 by a torsion spring. Under the reset action of the torsion spring, the first mounting bracket 101 and the second mounting bracket 108 are engaged with the outer wall of the cylinder by the two sets of clamping plates 113. By setting the clamping plates 113 installed by the torsion spring, when the lengths of the first mounting bracket 101 and the second mounting bracket 108 are fixed and locked, the first mounting bracket 101 and the second mounting bracket 108 can be clamped and engaged with the outer wall of the cylinder by the clamping plates 113 by the reset action of the torsion spring.

[0042] Please refer to the above embodiments for further details. Figure 6 and Figure 7 The second mounting bracket 108 has a fifth fitting groove 112 on both sides, and the first mounting bracket 101 has a limit screw 107 on both sides. When the first mounting bracket 101 and the second mounting bracket 108 are fitted together, the two sets of limit screws 107 extend into the first fitting groove 102 of the first mounting bracket 101 and are placed in the fifth fitting groove 112 of the second mounting bracket 108. The limit screws 107 are used to restrict the second mounting bracket 108 from being pulled out of the first mounting bracket 101. By setting the limit screws 107 and the fifth fitting groove 112, the second mounting bracket 108 cannot be pulled out after being engaged in the first mounting bracket 101.

[0043] Please refer to the above embodiments for further details. Figure 6 and Figure 7 The first mounting bracket 101 has a third fitting groove 104 on its inner side, and the second mounting bracket 108 has a fitting plate 109 on its inner side. The fitting plate 109 and the third fitting groove 104 fit together. By setting the third fitting groove 104 and the fitting plate 109, the stability of the combination of the first mounting bracket 101 and the second mounting bracket 108 can be improved.

[0044] In the above embodiments, please refer to the specific examples. Figure 6 The top of the first mounting bracket 101 is provided with a fixing screw 106, which extends into the interior of the third fitting groove 104. The fixing screw 106 is used to lock the positions of the first mounting bracket 101 and the second mounting bracket 108. By setting the fixing screw 106, the positions of the first mounting bracket 101 and the second mounting bracket 108 can be locked.

[0045] In the above embodiments, please refer to the specific examples. Figure 4 The top of the interlocking plate 109 is provided with a second anti-slip area 110, and the top of the first mounting bracket 101 is provided with a first anti-slip area 105. By providing anti-slip areas, the position of the inductive switch 2 can be limited.

[0046] Please refer to the above embodiments for further details. Figure 8A pressure plate 5 is mounted on the side of the inductive switch 2 via a torsion spring. Under the reset action of the torsion spring, the pressure plate 5 is in contact with the first anti-slip area 105 and the second anti-slip area 110. By setting the pressure plate 5 to fit the anti-slip area, the inductive switch 2 can be fixed in position.

[0047] Please refer to the above embodiments for further details. Figure 4 The first anti-slip area 105 and the second anti-slip area 110 are both treated with a frosting process to improve local friction. By frosting the anti-slip areas, the friction can be improved, thereby improving the effect of fixing the position of the inductive switch 2. The anti-slip areas can also be made of materials with a high coefficient of friction, such as rubber.

[0048] In practical operation, the following steps are required: First, the mounting component 1 needs to be assembled. The first limiting block 3 on the side of the inductive switch 2 is aligned with the second fitting groove 103 of the first mounting bracket 101. The inductive switch 2 is then slidably installed into the first mounting bracket 101. Then, the second mounting bracket 108 is slidably inserted into the first fitting groove 102 of the first mounting bracket 101. At the same time, the fitting plate 109 of the second mounting bracket 108 is inserted into the third fitting groove 104 of the first mounting bracket 101. When the second mounting bracket 108 is inserted into the first mounting bracket 101, the fourth fitting groove 111 of the second mounting bracket 108 engages with the second limiting block 4 on the side of the inductive switch 2.

[0049] Next, limit screws 107 are installed on both sides of the first mounting bracket 101. The limit screws 107 are used to engage with the fifth fitting groove 112 on the side of the second mounting bracket 108, thereby preventing the second mounting bracket 108 from being pulled out of the first mounting bracket 101. Then, the lengths of the first mounting bracket 101 and the second mounting bracket 108 are adjusted according to the length of the cylinder. Then, fixing screws 106 are installed in the second mounting bracket 108 to lock the first mounting bracket 101 and the second mounting bracket 108, so that the lengths of the first mounting bracket 101 and the second mounting bracket 108 are fixed. Next, the clamping plates 113 at the ends of the first mounting bracket 101 and the second mounting bracket 108 are pried open. The clamping plates 113 are installed by setting torsion springs. The two sets of clamping plates 113 are used to engage the first mounting bracket 101 and the second mounting bracket 108 with the outer wall of the cylinder.

[0050] Next, the cylinder control system needs to be connected to adjust the cylinder's control stroke. The induction switch 2 is connected to the cylinder control system. During adjustment, press the pressure plate 5 on the side of the induction switch 2. The pressure plate 5 is also installed using a torsion spring. Pressing the pressure plate 5 raises the induction switch 2 so that its position can be arbitrarily slid. Then, the induction switch 2 slides in the second fitting groove 103 through the first limiting block 3 and slides in the fourth fitting groove 111 through the second limiting block 4. This allows the induction switch 2 to be adjusted smoothly whether it is adjusted to the first mounting bracket 101 or the second mounting bracket 108. When the position of the induction switch 2 is accurately adjusted, release the pressure plate 5. Use the pressure of the torsion spring to press the pressure plate 5 against the first anti-slip area 105 or the second anti-slip area 110 to limit the position of the induction switch 2. Similarly, it is also more convenient to adjust the position of the induction switch 2 later.
