Description

Technical Field

[0001] The utility model relates to the field of four-way electromagnetic safety door switches, in particular to a fixing structure for a four-way electromagnetic safety door switch. Background Art

[0002] The four-way electromagnetic safety door switch is a more advanced safety protection device. Similar to the two-way electromagnetic safety door switch, the four-way electromagnetic safety door switch also realizes the switching of the switch state through electromagnetic action and mechanical structure. When the safety door is closed, the electromagnetic part generates a magnetic field, attracting the moving parts of the mechanical switch part, so that the switches of the four channels are in a closed state, allowing the safety system to operate normally. Once the safety door is opened, the magnetic field disappears, and the moving parts bounce off under the action of devices such as springs, and the switches of the four channels are simultaneously disconnected. The safety system receives the signal and takes corresponding safety measures. The four-way electromagnetic safety door switch is larger in volume than the two-way electromagnetic safety door switch.

[0003] After the applicant searched for the fixing methods of the existing published four-way electromagnetic safety door switches, the following problems were found: Most of the existing fixing methods of the four-way electromagnetic safety door switches are to use a large number of external bolts to connect and fix to the installation position. When it is necessary to disassemble, repair or replace the four-way electromagnetic safety door switch, it is necessary to turn a large number of external bolts again for disassembly, and the re-fixing is also time-consuming. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a fixing structure for a four-way electromagnetic safety door switch, aiming to solve the problem that most of the existing fixing methods of the four-way electromagnetic safety door switches are to use a large number of external bolts to connect and fix to the installation position. When it is necessary to disassemble, repair or replace the four-way electromagnetic safety door switch, it is necessary to turn a large number of external bolts again for disassembly, and the re-fixing is also time-consuming.

[0005] To achieve the above object, a fixing structure for a four-way electromagnetic safety door switch proposed by the utility model includes a four-way electromagnetic safety door switch body. A fixing mechanism is arranged at the rear side of the four-way electromagnetic safety door switch body, and an aluminum heat conducting strip is arranged at the rear side of the fixing mechanism.

[0006] The fixing mechanism includes two card rails, a fixing plate and a fixing clamp. The rear side of the fixing clamp is fixedly connected to the front side of the fixing plate, and the rear side of the card rail is fixedly connected to the front side of the fixing plate.

[0007] Preferably, clamping strips are fixedly connected to both sides of the four-way electromagnetic safety door switch body. The clamping strips are movably inserted into the interior of the card rails, and a handle is fixedly connected between the tops of the two clamping strips.

[0008] Preferably, a limiting plate is fixedly connected to the bottom of the four-way electromagnetic safety door switch body. A clamping block is fixedly connected to the front side of the limiting plate, and the top of the clamping block contacts the bottom of the fixed clamp.

[0009] Preferably, the limiting plate is made of elastic plastic, and chamfers are provided on both the front side and the rear side of the bottom of the clamping strip.

[0010] Preferably, a fixing block is fixedly connected to the bottom of the limiting plate, and an anti-slip block is fixedly connected to the front side of the fixing block. The number of anti-slip blocks is several and they are evenly distributed on the front side of the fixing block.

[0011] Preferably, pressing blocks are fixedly connected to both sides of the front side of the fixing plate. An anti-slip strip is fixedly connected to the front side of the pressing block. The number of anti-slip strips is several and they are evenly distributed on the front side of the pressing block.

[0012] Preferably, through grooves are formed in the fixing plate. The number of the aluminum heat conducting strips and the through grooves is several. The surface of the aluminum heat conducting strip is fixedly connected to the inner wall of the through groove. The front side of the aluminum heat conducting strip contacts the rear side of the four-way electromagnetic safety door switch body, and the rear side of the aluminum heat conducting strip is in the same plane as the rear side of the fixing plate.

[0013] Preferably, mounting holes are formed at the four corners of the front side of the fixing plate.

[0014] In the technical solution of the present utility model, by pressing backward through the hand-held anti-slip strip, the fixing plate can be conveniently pressed against the installation position. An external bolt is used to pass through the installation hole, and the external bolt is threadedly connected to the installation position, so as to conveniently fix the fixing plate. At this time, the rear side of the aluminum heat-conducting strip will contact the installation position. Then, hold the handle and move the four-way electromagnetic safety door switch body and the card strip until the card strip is inserted into the inside of the card rail. Since chamfers are provided on both the front side and the rear side of the bottom of the card strip, it is convenient for the card strip to be inserted into the inside of the card rail. During the process of completely inserting the card strip into the card rail, the card block is squeezed by the fixed card. Since the limiting plate is made of elastic plastic, the limiting plate can be deformed, so that the card block can cross the fixed card. At this time, the limiting plate rebounds, so that the top of the card block contacts the bottom of the fixed card. At this time, the fixed card can limit the card block, the limiting plate and the four-way electromagnetic safety door switch body, and the fixation of the four-way electromagnetic safety door switch body is completed. When it is necessary to disassemble, repair or replace the four-way electromagnetic safety door switch body, press the anti-slip block to make the fixed block move backward. At this time, the limiting plate can be deformed backward, so that the card block is separated from the contact with the fixed card. Then, hold the handle and pull it upward, so that the card strip is separated from the contact with the card rail, and the four-way electromagnetic safety door switch body can be quickly disassembled, repaired or replaced. When installing again, insert the card strip into the card rail, so that the top of the card block contacts the bottom of the fixed card, and the four-way electromagnetic safety door switch body can be quickly fixed. The disassembly and secondary installation of the four-way electromagnetic safety door switch body are more convenient and fast, avoiding the problem that most of the existing fixing methods of the four-way electromagnetic safety door switch are to use a large number of external bolts to connect and fix with the installation position. When it is necessary to disassemble, repair or replace the four-way electromagnetic safety door switch, it is necessary to rotate a large number of external bolts again for disassembly, and the re-fixation is also time-consuming. The heat generated by the four-way electromagnetic safety door switch body during operation is conducted to the fixed position with a larger surface area through the aluminum heat-conducting strip, so as to accelerate the heat dissipation of the four-way electromagnetic safety door switch body.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0027] Moreover, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0028] The present utility model provides a fixed structure for a four-way electromagnetic safety door switch, aiming to solve the problem that most of the existing fixing methods for four-way electromagnetic safety door switches are to use a large number of external bolts to connect and fix to the installation position. When it is necessary to disassemble, repair or replace the four-way electromagnetic safety door switch, it is necessary to rotate a large number of external bolts again for disassembly, and the re-fixing is also time-consuming.

[0029] As Figures 1-6 shown, a fixed structure for a four-way electromagnetic safety door switch provided by an embodiment of the present utility model includes a four-way electromagnetic safety door switch body 1. A fixing mechanism 2 is arranged at the rear side of the four-way electromagnetic safety door switch body 1, and an aluminum heat conducting strip 6 is arranged at the rear side of the fixing mechanism 2;

[0030] The fixing mechanism 2 includes two card rails 201, a fixing plate 202 and a fixing clip 203. The rear side of the fixing clip 203 is fixedly connected to the front side of the fixing plate 202, and the rear side of the card rail 201 is fixedly connected to the front side of the fixing plate 202.

[0031] In the technical solution of the present utility model, by pressing the hand-held anti-slip strip 13 backward, the fixing plate 202 can be easily pressed against the installation position. An external bolt is used to pass through the installation hole 4, and the external bolt is threadedly connected to the installation position, so as to facilitate the fixation of the fixing plate 202. At this time, the rear side of the aluminum heat conduction strip 6 will contact the installation position. Then, hold the handle 5 and move the four-way electromagnetic safety door switch body 1 and the clamping strip 8 until the clamping strip 8 is inserted into the inside of the clamping rail 201. Since chamfers are provided on the front side and the rear side of the bottom of the clamping strip 8, it is convenient for the clamping strip 8 to be inserted into the inside of the clamping rail 201. During the process of completely inserting the clamping strip 8 into the clamping rail 201, the clamping block 12 is squeezed by the fixed clamp 203. Since the limiting plate 9 is made of elastic plastic, the limiting plate 9 can be deformed, so that the clamping block 12 can cross the fixed clamp 203. At this time, the limiting plate 9 rebounds, so that the top of the clamping block 12 contacts the bottom of the fixed clamp 203. At this time, the fixed clamp 203 can limit the clamping block 12, the limiting plate 9 and the four-way electromagnetic safety door switch body 1, and the fixation of the four-way electromagnetic safety door switch body 1 is completed. When it is necessary to disassemble, repair or replace the four-way electromagnetic safety door switch body 1, press the anti-slip block 11 to make the fixed block 10 move backward. At this time, the limiting plate 9 can be deformed backward, so that the clamping block 12 is separated from the fixed clamp 203. Then, hold the handle 5 and pull it upward, so that the clamping strip 8 is separated from the clamping rail 201, and the four-way electromagnetic safety door switch body 1 can be quickly disassembled, repaired or replaced. When installing again, insert the clamping strip 8 into the clamping rail 201, so that the top of the clamping block 12 contacts the bottom of the fixed clamp 203, and the four-way electromagnetic safety door switch body 1 can be quickly fixed. The disassembly and secondary installation of the four-way electromagnetic safety door switch body 1 are more convenient and fast, avoiding the problem that most of the existing fixing methods of the four-way electromagnetic safety door switch are to use a large number of external bolts to connect and fix with the installation position. When it is necessary to disassemble, repair or replace the four-way electromagnetic safety door switch, it is necessary to rotate a large number of external bolts again for disassembly, and the re-fixation is also time-consuming. Through the aluminum heat conduction strip 6, the heat generated when the four-way electromagnetic safety door switch body 1 works is conducted to the fixed position with a larger surface area, so as to accelerate the heat dissipation of the four-way electromagnetic safety door switch body 1.

[0032] Please refer to Figure 1 and Figure 4 On both sides of the four-way electromagnetic safety door switch body 1, clamping strips 8 are fixedly connected, and the clamping strips 8 are movably inserted into the inside of the clamping rail 201. A handle 5 is fixedly connected between the tops of the two clamping strips 8. In this embodiment, by holding the handle 5 and moving the four-way electromagnetic safety door switch body 1 and the clamping strip 8 into the inside of the clamping rail 201, the four-way electromagnetic safety door switch body 1 can be connected to the fixing plate 202, achieving the effect of conveniently connecting the four-way electromagnetic safety door switch body 1 and the fixing plate 202.

[0033] For further information, please refer to Figure 3 and 5 The bottom of the four-way electromagnetic safety door switch body 1 is fixedly connected to a limit plate 9, the front side of the limit plate 9 is fixedly connected to a clamping block 12, and the top of the clamping block 12 contacts the bottom of the fixed clamp 203. In this embodiment, by moving the four-way electromagnetic safety door switch body 1 downward until the top of the clamping block 12 contacts the bottom of the fixed clamp 203, the four-way electromagnetic safety door switch body 1 can be prevented from moving upward, and the four-way electromagnetic safety door switch body 1 can be limited to the front side of the fixed plate 202, thereby achieving the effect of conveniently limiting the four-way electromagnetic safety door switch body 1 to the front side of the fixed plate 202.

[0034] Please continue to refer to Figure 4 and Figure 5 The limiting plate 9 is made of elastic plastic, and the front and rear sides of the bottom of the clip strip 8 are both chamfered. In this embodiment, since the limiting plate 9 is made of elastic plastic, the limiting plate 9 can be deformed, which facilitates the block 12 to move to the top of the block 12 to contact the bottom of the fixed card 203. By providing chamfers on the front and rear sides of the bottom of the clip strip 8, the clip strip 8 can be easily inserted into the inside of the clip rail 201, achieving the effect of facilitating the deformation of the limiting plate 9 and facilitating the insertion of the clip strip 8 into the inside of the clip rail 201.

[0035] Please refer to Figure 5 The bottom of the limit plate 9 is fixedly connected with a fixed block 10, and the front side of the fixed block 10 is fixedly connected with an anti-sliding block 11, and the number of anti-sliding blocks 11 is several and evenly distributed on the front side of the fixed block 10. In this embodiment, by pressing the anti-sliding block 11 to move the fixed block 10 backward, the limit plate 9 can be deformed backward, so that the clamping block 12 is out of contact with the fixed clamp 203, so as to facilitate the limit plate 9 to be pressed backward.

[0036] Also, please refer to Figure 1 and Figure 6 The two sides of the front side of the fixing plate 202 are fixedly connected with the pressing blocks 3, and the front side of the pressing blocks 3 is fixedly connected with the anti-slip strips 13, and the number of the anti-slip strips 13 is several and evenly distributed on the front side of the pressing blocks 3. In this embodiment, by holding the anti-slip strips 13 and pressing them backward, the fixing plate 202 can be conveniently pressed against the installation position, and the external bolts can be conveniently passed through the installation holes 4, and the external bolts can be threadedly connected with the installation position, so as to facilitate the fixing of the fixing plate 202, thereby achieving the effect of conveniently fixing the fixing plate 202.

[0037] Please refer to Figure 1 and Figure 2, a through groove 7 is formed inside the fixing plate 202. The number of aluminum heat conducting strips 6 and the through groove 7 is several. The surface of the aluminum heat conducting strip 6 is fixedly connected to the inner wall of the through groove 7. The front side of the aluminum heat conducting strip 6 contacts the rear side of the four-way electromagnetic safety door switch body 1, and the rear side of the aluminum heat conducting strip 6 is in the same plane as the rear side of the fixing plate 202. In this embodiment, the heat generated when the four-way electromagnetic safety door switch body 1 works is conducted to a fixed position with a larger surface area through the aluminum heat conducting strip 6, so as to accelerate the heat dissipation of the four-way electromagnetic safety door switch body 1, achieving the effect of facilitating the acceleration of the heat dissipation of the four-way electromagnetic safety door switch body 1.

[0038] In addition, please refer to Figure 1 , mounting holes 4 are formed at the four corners of the front side of the fixing plate 202. In this embodiment, by using an external bolt to pass through the mounting hole 4 and thread the external bolt with the mounting position, it is convenient to fix the fixing plate 202, achieving the effect of conveniently fixing the fixing plate 202 at the mounting position.

[0039] It should be noted that the four-way electromagnetic safety door switch is a mature technology that has been published and has various shapes, which will not be elaborated here.

[0040] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention.
