Description

Technical Field

[0001] The invention relates to the technical field of porous ceramics, in particular to an adjustable connection device between porous ceramics and a heating wire. Background Art

[0002] Porous ceramics have the advantage of high porosity, so they can transfer heat stably and efficiently.

[0003] Porous ceramics are generally used in conjunction with heating wires. Porous ceramics provide a stable environment for heat transfer; the heating wire acts as an efficient heat source and generates heat rapidly when powered on. When the two are combined, heat quickly diffuses from the wire to the ceramic, achieving precise and stable temperature control.

[0004] When connecting porous ceramics and heating wires, the porous ceramics are usually installed on a connecting device to ensure that the position of the porous ceramics is relatively stable. However, the existing connecting device is not convenient for positioning the porous ceramics before installation, so when installing the porous ceramics, the installation position of the porous ceramics may be repeatedly debugged, thereby increasing the installation time of the porous ceramics. Summary of the Invention

[0005] In order to solve the technical problems in the background technology, the present invention discloses an adjustable connection device between porous ceramics and a heating wire.

[0006] The present invention provides an adjustable connection device for porous ceramic and heating wire, comprising porous ceramic and heating wire, which are mounted on a connection frame, wherein the porous ceramic is arranged horizontally and a protruding connection seat is provided at the lower end thereof;

[0007] The connecting frame includes a base, the base is provided with a connecting groove, and the connecting seat is inserted into the connecting groove;

[0008] The side wall of the connecting seat is provided with a raised spherical positioning bead, which is elastically connected by a first spring and is used to engage with the positioning groove of the connecting groove wall;

[0009] The base is also provided with a slidable fixing rod, through which the fixing rod can be inserted into the plug hole of the connecting seat or detached from the connecting seat;

[0010] The base is also provided with a lifting assembly for driving the lifting plate to move up and down;

[0011] A clamping assembly is provided below the lifting plate to fix the heating wire;

[0012] When the lifting plate descends, it is also used to adjust the pressure between the heating wire and the porous ceramic;

[0013] A horizontally arranged slide bar is provided at the lower end of the lifting plate, and two first sliders are slidably connected to the slide bar; a second spring is sleeved on the slide bar and is located between the two first sliders;

[0014] A hinge plate is connected between the first slider and the clamping assembly in a hinged manner;

[0015] When the heating wire contacts the porous ceramic and generates pressure, the second spring is in a compressed state.

[0016] The connecting seat is plugged into the connecting groove, and the positioning bead is clamped into the positioning groove to achieve preliminary positioning of the porous ceramic; the fixing rod is plugged into the inside of the connecting seat to fix the position of the porous ceramic; the beneficial effects of the above arrangement are: 1. The positioning accuracy and stability of the porous ceramic are improved; 2. On the basis of the positioning bead being clamped into the positioning groove, the fixing rod can be accurately inserted into the connecting seat; 3. The elastic connection of the positioning bead and the sliding connection of the fixing rod can achieve quick disassembly and assembly of the porous ceramic and the base; 4. The lifting assembly can not only realize the lifting and lowering of the heating wire, but also adjust the pressure between the heating wire and the porous ceramic, thereby improving the heat transfer performance of the porous ceramic; 5. When the second spring is compressed, its restoring force will be transmitted to the heating wire through the hinge plate, so that when the initial pressure changes due to factors such as thermal expansion and contraction, component aging, etc., the heating wire and the porous ceramic are still kept in close contact, and the performance is stable; 6. The installation structure of the second spring makes the pressure applied by the second spring to the first slider consistent, so that the pressure applied by the hinge plate to the heating wire is stable, and there will be no uneven force on the heating wire.

[0017] The specific structure of the lifting assembly is: it includes a support plate, which is connected to the base through a pillar; a guide column and a screw rod are also connected between the support plate and the base; the lifting plate is provided with a screw nut threadedly connected to the screw rod, and is also provided with a second slider slidingly connected to the guide column.

[0018] The conventional guide pillars are set as four symmetrical ones in pairs, and the lifting plate is slidably connected to the guide pillars; a screw rod is provided, the lower end of which is fixedly connected to the upper end of the lifting plate, and a screw nut threadedly connected to the screw rod is set on the top of the support plate, its position is fixed, and it can rotate in place through the bearing, thereby driving the screw rod to rise and fall, and driving the lifting plate to rise and fall; the above structure has the following defects: 1. The screw rod has a large load, which is easy to affect the overall stability and life; 2. The screw rod protrudes upward from the support plate, which not only forms a sharp part, causing a safety hazard, but also the lubricating oil on the screw rod is easily contaminated by foreign objects, causing foreign object pollution; based on this, further improvements are: both the guide pillars and the screw rod are set as two; the positions of the guide pillars and the screw rod form a square, and the guide pillar is located at a diagonal position, and the screw rod is also located at a diagonal position; a pulley is connected to the screw rod, and a belt is connected between the pulleys to achieve synchronous rotation. The beneficial effects of such a setting are: 1. In terms of load capacity, the two screws can distribute the load more evenly, reduce the pressure on a single screw, reduce the risk of deformation and wear, and have stronger load-bearing capacity; 2. The belt linkage ensures consistent height changes on both sides, avoids tilting and jamming of components, and improves stability; 3. The double screws and guide columns form a stable guide system with more constraints, can move precisely along a straight line trajectory, reduce lateral deviation and swing, and the screw wear is relatively small, and the accuracy can still be maintained after long-term use.

[0019] The clamping assembly comprises a horizontally arranged fixed box; a vertically arranged guide rod within the fixed box, and a connecting plate that slots onto the guide rod to achieve lift and lowering guidance. The lower end of the connecting plate is connected to a clamping plate located below the fixed box, sandwiching the heating wire between the fixed box and the clamping plate. The threaded end of the locking bolt is inserted downward into the fixed box and threadedly connected to the connecting plate. The connecting plate is raised and lowered by tightening the locking nut. This clamping method allows the device to accommodate different types of heating wires, providing greater versatility.

[0020] In order to improve the position stability of the heating wire, a further design is: the connecting plate and the clamping plate are connected by connecting rods arranged at intervals; the heating wire is arranged in a serpentine shape, so that the connecting rod is located at the bottom and notch of the U-shaped groove formed by the heating wire.

[0021] The fixing rod is separated from the connecting seat by manual pulling, which is a cumbersome operation and will reduce the disassembly efficiency of the porous ceramics. Based on this, further improvements are as follows: the fixing rod is elastically connected to the base through a tension spring; when the tension spring is in a free state, the fixing rod is away from the connecting seat; when the fixing rod is inserted into the socket hole under external force, the tension spring is in a stretched state.

[0022] Under the action of the tension spring, in order to maintain the structural stability of the fixed rod inserted into the connecting seat, an additional linear drive mechanism is required to apply pressure and thrust to the outer end of the fixed rod. This is not only structurally complex but also costly. Based on this, further improvements are made in that: the outer end of the fixed rod is connected to a fixing plate; when the fixing plate is against the base and fixed, the fixed rod is inserted into the socket hole.

[0023] The beneficial effects of the present invention are: 1. It improves the positioning accuracy and stability of the porous ceramics; 2. On the basis of the positioning beads being clamped in the positioning grooves, the fixing rod can be accurately inserted into the connecting seat; 3. The positioning beads are elastically connected and the fixing rods are slidingly connected, so that the porous ceramics and the base can be quickly disassembled and assembled; 4. The lifting assembly can not only realize the lifting and lowering of the heating wire, but also adjust the pressure between the heating wire and the porous ceramics, thereby improving the heat transfer performance of the porous ceramics; 5. When the second spring is compressed, its restoring force will be transmitted to the heating wire through the hinge plate, so that when the initial pressure changes due to factors such as thermal expansion and contraction, and aging of components, the heating wire and the porous ceramics are still kept in close contact, and the performance is stable; 6. The installation structure of the second spring makes the pressure applied by the second spring to the first slider consistent, so that the pressure applied by the hinge plate to the heating wire is stable, and there will be no uneven force on the heating wire.

DETAILED DESCRIPTION

[0035] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0036] like Figure 1-9 As shown, the present invention discloses an adjustable connection device between a porous ceramic and a heating wire, comprising a porous ceramic 1 and a heating wire 2, which are installed on a connection frame.

[0037] The connecting frame includes a square, horizontally arranged base 4, with a recessed cylindrical connecting groove 5 provided at the center of the upper end of the base 4. The porous ceramic 1 is also arranged horizontally, with a raised, cylindrical connecting seat 3 provided at the center of its lower end, which is inserted into the connecting groove 5. The groove wall of the connecting groove 5 is provided with two symmetrically arranged, recessed spherical positioning grooves 8; the side wall of the connecting seat 3 is provided with two horizontally arranged first placement grooves, in which a first spring 7 is inserted. The outer end of the first spring 7 is connected to a spherical positioning bead 6, which protrudes from the side wall of the connecting seat 3 and is used to engage the positioning groove 8 to achieve preliminary positioning of the porous ceramic 1.

[0038] The base 4 is also provided with two horizontally arranged second placement grooves, which are perpendicular to the first placement grooves. The inner end of the second placement groove is connected to the connecting groove 5, and the outer end passes through the side wall of the base 4. A fixing rod 9 is inserted into the second placement groove. An inwardly protruding inner convex ring is provided at the connection between the second placement groove and the connecting groove 5. The outer end of the second placement groove is connected to a plug 32 that is sleeved with the fixing rod 9. The plug 32 is fixed to the base 4 by a threaded connection. A limit ring that protrudes outward is provided near the inner end of the fixing rod 9. The limit ring abuts against the inner convex ring to achieve the insertion and limiting of the fixing rod 9. A tension spring 28 is sleeved on the fixing rod 9. One end of the tension spring 28 is fixedly connected to the limit ring, and the other end is fixedly connected to the plug 32. When the tension spring 28 is in its natural state, the inner end of the fixing rod 9 is away from the connecting groove 5. When the fixing rod 9 is pushed by an external force, the inner end of the fixing rod 9 is inserted into the insertion hole. At this time, the tension spring 28 is in a stretched state. In this way, when the fixing rod 9 loses the external force, it automatically detaches from the connecting seat 3, thereby facilitating the disassembly and assembly of the porous ceramic 1. When the fixing rod 9 is inserted into the insertion hole, the position of the porous ceramic 1 is defined, improving the position accuracy and stability of the porous ceramic 1. In addition, based on the positioning bead 6 engaging the positioning groove 8, the fixing rod 9 can be accurately inserted into the connecting seat 3.

[0039] The outer end of the fixing rod 9 is also connected to a fixing plate 29. When the fixing rod 9 needs to be inserted into the plug hole, the fixing plate 29 is fixed to the base 4 by bolts, thereby maintaining the structural stability of the fixing rod 9 inserted into the plug hole.

[0040] A horizontally arranged support plate 15 is provided directly above the base 4 and is connected to the base 4 through a pillar 16; a guide column 17 and a screw rod 18 are also connected between the support plate 15 and the base 4; the horizontally arranged lifting plate 10 is provided with a screw nut 19 threadedly connected to the screw rod 18, and is also provided with a second slider 20 slidingly connected to the guide column 17.

[0041] The conventional guide posts 17 are provided with four symmetrical ones in pairs, and the lifting plate 10 is slidably connected to the guide posts 17; a screw rod 18 is provided, the lower end of which is fixedly connected to the upper end of the lifting plate 10, and a screw nut 19 threadedly connected to the screw rod 18 is provided on the top of the support plate 15, its position is fixed, and it can rotate in situ through the bearing, thereby driving the screw rod 18 to rise and fall, and driving the lifting plate 10 to rise and fall; the above structure has the following defects: 1. The screw rod 18 has a large load, which is easy to affect the overall stability and life; 2. The screw rod 18 protrudes upward from the support plate 15, which not only forms a sharp part, causing a safety hazard, but also the lubricating oil on the screw rod 18 is easily contaminated by foreign objects, causing foreign object pollution; therefore, the following design is made: two guide posts 17 and screw rod 18 are each provided; the positions of the guide posts 17 and screw rod 18 form a square, and the guide posts 17 are located at a diagonal position, and the screw rod 18 is also located at a diagonal position; a pulley 21 is connected to the screw rod 18, and a belt 30 is connected between the pulleys 21 to achieve synchronous rotation. One of the screws 18 protrudes upward from the support plate 15 and is fixedly connected to a handle 33, making it easy to operate manually. The beneficial effects of this arrangement are: 1. In terms of load capacity, the two screws 18 can more evenly distribute the load, reducing the pressure on a single screw 18, reducing the risk of deformation and wear, and having a stronger load-bearing capacity; 2. The belt linkage ensures consistent height changes on both sides, avoiding tilting and jamming of components, and improving stability; 3. The dual screws 18 and guide posts 17 form a stable guide system with more constraints, capable of precise movement along a straight line, reducing lateral deviation and swing, and relatively little wear on the screws 18, so that accuracy can be maintained after long-term use.

[0042] The lower end of the lifting plate 10 is provided with two symmetrical, horizontally arranged sliding rods 11 close to the edge of the lifting plate 10 , and two first sliders 12 are slidably connected to the sliding rods 11 ; a second spring 13 located between the two first sliders 12 is sleeved on the sliding rod 11 .

[0043] A horizontally arranged fixed box 22 is provided below the lifting plate 10. A hinge plate 14 is connected between the fixed box 22 and the first slider 12. The two ends of the hinge plate 14 are hinged to the fixed box 22 and the slider, respectively. The hinge plates 14 on the same slide bar 11 form a wedge shape with the opening flared downward.

[0044] like Figure 8As shown, four guide rods 23 are arranged vertically in a square shape in the fixed box 22. The upper and lower ends of the guide rods 23 are fixedly connected to the upper and lower plates of the fixed box 22 respectively. The horizontally arranged connecting plate 24 is sleeved on the guide rods 23 to achieve lifting and lowering guidance. The connecting plate 24 has protruding plates 31 extending outward on both sides. The lower end of the protruding plate 31 is connected to the clamping plate 25 through a connecting rod 27. The heating wire 2 is clamped between the fixed box 22 and the clamping plate 25; the threaded end of the locking bolt is inserted downward into the fixed box 22 and is threadedly connected to the connecting plate 24; the connecting plate 24 is driven to rise and fall by tightening the locking nut 26. Fixing the heating wire 2 by clamping can make this device applicable to different models of heating wires 2, and has higher versatility. The heating wire 2 is arranged in a serpentine shape, so that the connecting rod 27 is located at the bottom and notch of the U-shaped groove formed by the heating wire 2 to improve the position stability of the heating wire 2. The convex plate 31 is provided so that when the heating wire 2 is fixed, the clamping plate 25 and the porous ceramic 1 are staggered to avoid contact between the clamping plate 25 and the porous ceramic 1 .

[0045] The connecting seat 3 is plugged into the connecting groove 5, and the positioning bead 6 is clamped into the positioning groove 8 to achieve the preliminary positioning of the porous ceramic 1; the fixing rod 9 is inserted into the inside of the connecting seat 3 to fix the position of the porous ceramic 1; compared with the existing technology, the beneficial effects of this embodiment are: 1. The position accuracy and stability of the porous ceramic 1 are improved; 2. On the basis of the positioning bead 6 clamping the positioning groove 8, the fixing rod 9 can be accurately inserted into the connecting seat 3; 3. The positioning bead 6 is elastically connected and the fixing rod 9 is slidably connected, which can realize the quick disassembly and assembly of the porous ceramic 1 and the base 4; 4. The lifting component can not only realize the lifting and lowering of the heating wire 2, but also It can adjust the pressure between the heating wire 2 and the porous ceramic 1, thereby improving the heat transfer performance of the porous ceramic 1; 5. When the second spring 13 is compressed, its restoring force will be transmitted to the heating wire 2 through the hinge plate 14, so that when the initial pressure changes due to factors such as thermal expansion and contraction, component aging, etc., the heating wire 2 and the porous ceramic 1 are still kept in close contact, and the performance is stable; 6. The installation structure of the second spring 13 makes the pressure applied by the second spring 13 to the first slider 12 remain consistent, so that the pressure applied by the hinge plate 14 to the heating wire 2 is stable, and there will be no uneven force on the heating wire 2.

[0046] When the present invention is used, the base 4 is used as an indirect heat source. Since the lower side of the porous ceramic 1 is in contact with the base 4 and the porous ceramic 1 can evenly transfer heat, the base is heated evenly and can also evenly transfer heat.

[0047] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
