Description

Technical Field

[0001] This invention relates to docking fixtures, and more specifically to a docking fixture for a cage-type sensor bracket. Background Technology

[0002] Cage-type sensor supports are commonly used structures for measuring ground motion parameters in geotechnical engineering and geological exploration. They are used to mount ground motion sensors into the soil or rock medium to be measured. Since it is generally necessary to measure ground motion parameters over a distance of tens of meters, the required sensor support length is relatively long, necessitating the use of multiple sensor support sections connected together.

[0003] Figure 1 The diagram shows the docking process of two sensor bracket sections 1. Each sensor bracket section 1 to be docked includes four vertically arranged steel bars 13, a lower connector 12 located at the lower end of the four steel bars 13, and an upper connector 11 located at the upper end of the four steel bars 13. Both the upper connector 11 and the lower connector 12 are open cylindrical shapes, and their openings correspond to each other. Shoulders are provided on the outer side wall of the upper connector 11 and the inner side wall of the lower connector 12. The upper ends of the four steel bars 13 are lower than the shoulders outside the upper connector 11. The upper connector 11 has four threaded holes, which are located between the upper end face of the four steel bars 13 and the corresponding shoulder face, respectively. The lower ends of the four steel bars 13 protrude from the lower end of the lower connector 12, and the protruding parts have through holes.

[0004] When docking two sensor bracket sections 1, they must be precisely aligned axially and circumferentially. Specifically, the lower connector 12 (referred to as lower connector A) of the upper sensor bracket section 1 must be fitted together with the upper connector 11 (referred to as upper connector B) of the lower sensor bracket section 1, such that the lower end face of lower connector A contacts the outer shoulder surface of upper connector B, the upper end face of upper connector B contacts the inner shoulder surface of lower connector A, the lower end faces of the four steel bars in the upper sensor bracket section 1 contact the upper end faces of the four steel bars in the lower sensor bracket section 1, and the through holes on the four steel bars in the upper sensor bracket section correspond to the four threaded holes on upper connector B. Bolts are then installed in the corresponding through holes and threaded holes to complete the docking of the two sensor bracket sections.

[0005] However, the docking process currently lacks dedicated tooling and is mainly completed manually. Considering factors such as low processing precision, transportation deformation, and contamination of the docking surfaces, the following problems arise during the docking of the two sensor bracket sections:

[0006] (1) The sensor bracket is difficult to align axially:

[0007] To ensure reliable docking of the sensor brackets, the axial mating surfaces have a certain length. If the two sensor bracket sections are not fully aligned manually or if there is slight deformation of the mating surfaces, it is difficult to dock the sensor brackets in place (i.e., it is difficult to make the lower end face of the lower connector A contact the shoulder outside the upper connector B). Only with the help of external force can they be docked in place along the axial direction.

[0008] (2) Misalignment exists in the circumferential docking of the sensors:

[0009] Due to the limited wall thickness of the sensor bracket docking structure, it is difficult to set up a guiding structure. As a result, circumferential misalignment is very likely to occur during the docking process, which often leads to the threaded hole and the corresponding through hole not being aligned, thus making it impossible to complete the reliable docking of the sensor bracket.

[0010] (3) The docking posture is difficult to maintain for a long time:

[0011] After the two sensor brackets are docked, a reliable connection is achieved by tightening bolts. However, the docking environment is complex, and it is difficult to complete the reliable tightening of bolts in a short time. The docking posture of the sensor brackets needs to be maintained manually for a period of time, which is very labor-intensive.

[0012] (4) People are prone to injury:

[0013] Due to the lack of specialized tooling for sensor bracket docking, tasks such as axial docking, circumferential misalignment correction, and maintaining a tight docking posture often have to be done manually. This process is prone to causing hand pinching, cutting, and other injuries. Summary of the Invention

[0014] To address the technical problems of difficult, labor-intensive, and potentially dangerous docking of sensor brackets, this invention provides a docking fixture for cage-type sensor brackets.

[0015] To achieve the above objectives, the present invention adopts the following technical solution:

[0016] A docking fixture for a cage-type sensor bracket is characterized by including an axial docking unit and a circumferential docking unit.

[0017] The axial docking unit includes a U-shaped bracket and two clamping mechanisms symmetrically arranged on the two parallel arms of the U-shaped bracket;

[0018] The distance between the two parallel arms is greater than the maximum outer diameter of the sensor bracket, so that the U-shaped bracket can circumferentially surround the sensor bracket.

[0019] The clamping mechanism includes clamps and an adjustment assembly;

[0020] The working end of the clamp is located inside the U-shaped bracket and faces the center between the two parallel arms. It is used to clamp the corresponding upper and lower connectors in the two sensor brackets so that the two are tightly connected in the axial direction.

[0021] The adjustment component is rotatably connected to the clamp and movably connected to the U-shaped bracket, and is used to adjust the radial positional relationship between the working end of the clamp and the corresponding upper and lower connectors.

[0022] The circumferential docking unit is mounted on a U-shaped bracket, and its working end corresponds to one of the steel bars of the two sensor brackets to be docked, for rotating the sensor bracket corresponding to that steel bar.

[0023] Furthermore, the clamp includes an upper clamp, a lower clamp, an upper handle, and a lower handle;

[0024] Note: Both parallel arms of the U-shaped bracket are set along the X-direction, and its U-shaped bottom is set along the Y-direction;

[0025] The upper clamp includes an upper vertical bar arranged along the Z direction in the length direction and an upper horizontal bar connected to the inner side of the upper vertical bar along the Y direction; the inner side is the side close to the center of the U-shaped bracket;

[0026] The lower clamp includes a lower vertical bar arranged along the Z direction in the length direction and a lower horizontal bar connected to the inner side of the lower vertical bar along the Y direction; the lower horizontal bar and the upper horizontal bar are vertically corresponding; the lower vertical bar and the upper vertical bar are slidably connected, and their sliding direction is the Z direction;

[0027] One end of the upper handle is fixedly connected to the outside of the lower vertical bar, and the other end is used for hand gripping.

[0028] One end of the lower handle is hinged to the outside of the upper vertical bar and located below the upper handle, while the other end is used for hand gripping; the middle part of the lower handle is hinged to the middle part of the upper handle, so that when one end of the upper handle and the lower handle are close to each other, the other ends of the two are far apart.

[0029] The adjustment assembly is rotatably connected to the lower vertical rod.

[0030] Furthermore, the circumferential docking unit includes a sliding base fitted outside the U-shaped bottom of the U-shaped bracket, a rotating base rotatably mounted above the sliding base via a base pivot, a rack and pinion rod with a clearance fit in the middle and inserted inside the rotating base, a pivot mounted inside the rotating base and rotatably connected to the rotating base, a gear sleeved outside the pivot and meshing with the rack and pinion rod, and a rotating handle connected to one end of the pivot.

[0031] The base shaft between the rotating base and the sliding base extends into the sliding base;

[0032] The sliding base is threaded with a first set screw and a second set screw. The working end of the first set screw corresponds to the bottom sidewall of the U-shaped base, and the working end of the second set screw corresponds to the base shaft.

[0033] Both ends of the rack push rod are triangular wedge-shaped, used to contact the side wall of the steel bar.

[0034] Furthermore, the upper handle is a straight rod, and its length direction is set along the Y direction;

[0035] The lower handle is in the shape of a curved rod, with its middle part curving upwards to the middle of the upper handle. The curved part is hinged to the upper handle so that when one end of the upper handle and the lower handle are close to each other, the other ends of the two handles are far apart.

[0036] Furthermore, the clamp also includes a one-way check ratchet and a pawl;

[0037] The upper handle is provided with a handle through hole and a handle groove connected to each other along the Y direction.

[0038] One end of the one-way check ratchet is fixedly connected to the lower handle, and the other end extends into the handle through hole, with a gap between it and the side wall of the handle through hole, and its check teeth face the handle groove.

[0039] The pawl is located in the handle groove, and its working end corresponds to the check tooth of the one-way check ratchet. A compression spring is provided between the pawl and the side wall of the handle groove; the compression direction of the compression spring is Y.

[0040] Furthermore, the adjustment assembly includes a moving screw arranged along the Y direction in the length direction, and a screw wrench;

[0041] The moving screw is located above the upper handle. One end of it is rotatably connected to the lower vertical rod, the middle part is threadedly connected to the corresponding parallel arm of the U-shaped bracket, and the other end extends out of the corresponding parallel arm.

[0042] The screw wrench is detachably mounted on the other end of the moving screw and is used to rotate the moving screw.

[0043] Furthermore, a cover plate is provided outside the upper end of the groove of the handle;

[0044] The cover plate is detachably connected to the upper handle;

[0045] The pawl is provided with a cylindrical pawl handle; the pawl handle is axially arranged along the Z direction, its lower end is perpendicularly connected to the pawl, and its upper end extends out of the cover plate from the side of the cover plate near the one-way check ratchet, so that the pawl can be controlled to move along the Y direction to compress the compression spring.

[0046] Furthermore, the lower part of the upper horizontal bar away from the upper vertical bar is provided with a downward protruding rib;

[0047] The lower horizontal bar has an upward-protruding rib on the upper part of the end away from the lower vertical bar.

[0048] Furthermore, a protrusion is provided on the lower part of the middle of the upper handle;

[0049] The protrusion is provided with a waist-shaped hole in the Y direction of its length;

[0050] The waist-shaped hole extends through the protrusion along the X direction, and a pin is rotatably inserted inside it.

[0051] A connecting plate is provided on each of the two X-direction side walls at the bend of the lower handle. The two connecting plates are parallel to each other and are fixedly connected to both ends of the pin, thereby realizing the hinge connection between the lower handle and the upper handle.

[0052] Furthermore, the lower end of the upper vertical rod is provided with an upwardly extending groove; the groove connects the inner and outer sides of the upper vertical rod, and parallel Z-axis slide rails are respectively provided on the other two opposite side walls;

[0053] The lower vertical rod is located within the slide groove and is slidably connected to two Z-axis slide rails.

[0054] The beneficial effects of this invention are:

[0055] 1. The present invention provides a docking fixture for a cage-type sensor bracket, comprising an axial docking unit and a circumferential docking unit. The axial docking unit includes a U-shaped bracket with clamping mechanisms symmetrically arranged on both sides. The relative positions of the clamps and the upper and lower connectors to be docked are adjusted by adjusting the components to accommodate upper and lower connectors with different outer diameters, thereby enabling the clamps to accurately hold the upper and lower connectors and achieve smooth axial docking. Then, the circumferential docking unit achieves smooth circumferential docking. This greatly reduces the difficulty of docking, saves effort, prevents injury, and significantly improves the safety of docking operations.

[0056] 2. The present invention provides a docking fixture for a cage-type sensor bracket, which is provided with an upper clamp, a lower clamp, an upper handle and a lower handle; the upper clamp and the lower clamp respectively clamp the upper connector and the lower connector to be docked, and the upper handle and the lower handle control the relative position between the upper clamp and the lower clamp based on the lever principle, thereby realizing the axial docking of the upper connector and the lower connector and achieving the purpose of saving effort.

[0057] 3. The present invention provides a docking fixture for a cage-type sensor bracket. Its circumferential docking unit includes a sliding base, a rotating base, a rack and pinion, and a gear, etc., set on a U-shaped base. The sliding base can adjust the position of the rack and pinion so that its working end contacts the side wall of the steel strip. The rotating gear can drive the rack and pinion to push the side wall of the steel strip, thereby pushing the lower connector to rotate around the upper connector, thereby achieving precise circumferential docking of the upper and lower connectors and avoiding injury to personnel.

[0058] 4. The present invention provides a docking fixture for a cage-type sensor bracket. A one-way check ratchet is provided on the lower handle, and a pawl and a compression spring are provided on the upper handle. The one-way check ratchet extends into the upper handle and cooperates with the pawl and compression spring to achieve long-term locking of the relative positions of the upper and lower handles. This locks the relative positions of the upper and lower clamps for a long time, and further locks the axial positions of the upper and lower connectors to be docked for a long time. This allows sufficient time for circumferential misalignment adjustment of the upper and lower connectors and for tightening the bolts corresponding to each steel bar, greatly saving manpower.

[0059] 5. The present invention provides a docking fixture for a cage-type sensor bracket, which adopts a combination of a sliding base and a rotating base, and can realize the adjustment of any angle within the required range of the rack and pinion. That is, when the two sections of the sensor bracket to be docked are in any circumferential misalignment state, the rack and pinion can push the circumferentially misaligned sensor bracket to reset and align at a suitable angle.

[0060] 6. The present invention provides a docking fixture for a cage-type sensor bracket, wherein protrusions are provided on the upper part of the lower crossbar and the lower part of the upper crossbar, so that the upper end of the upper side clamp and the lower end of the lower side clamp are both hook-shaped, which can prevent the upper and lower joints of the sensor bracket from detaching from the clamp jaws during the clamping process.

[0067] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0068] The present invention provides a docking fixture for a cage-type sensor bracket, the docking fixture including an axial docking unit and a circumferential docking unit.

[0069] The axial docking unit includes a U-shaped bracket 2 and two clamping mechanisms 3 symmetrically arranged on the two parallel arms 21 of the U-shaped bracket 2.

[0070] Note: The two parallel arms 21 of the U-shaped bracket 2 are both set along the X direction, and its U-shaped bottom 22 is set along the Y direction.

[0071] like Figure 2 and Figure 3 As shown, the distance between the two parallel arms 21 of the U-shaped bracket 2 is greater than the maximum outer diameter of the sensor bracket 1 to be docked, so that the U-shaped bracket 2 can circumferentially surround the sensor bracket 1 to be docked, thereby making the two clamping mechanisms 3 symmetrically arranged on both sides of the sensor bracket 1 to be docked.

[0072] The clamping mechanism 3 includes a clamp; the working end of the clamp is located inside the U-shaped bracket 2 and faces the center between the two parallel arms 21, and is used to clamp the corresponding upper connector 11 and lower connector 12 in the two sections of the sensor bracket 1 to be docked, so that the two are tightly docked in the axial direction.

[0073] Specifically, such as Figure 4As shown, the clamps include an upper clamp 35, a lower clamp 32, an upper handle 31, and a lower handle 36. The upper clamp 35 includes an upper vertical bar 351 arranged along the Z direction and an upper horizontal bar 352 connected to the inner side of the upper vertical bar 351 along the Y direction. The inner side is the side close to the center of the U-shaped bracket 2. The lower end of the upper horizontal bar 352 away from the upper vertical bar 351 has a downward protruding rib, so that the upper end of the entire upper clamp 35 forms a hook shape. The lower clamp 32 includes a lower vertical bar 321 arranged along the Z direction and a lower horizontal bar 322 connected to the inner side of the lower vertical bar 321 along the Y direction. The upper end of the lower horizontal bar 322 away from the lower vertical bar 321 has an upward protruding rib, so that the lower end of the entire lower clamp 32 forms a hook shape. The lower horizontal bar 322 and the upper horizontal bar 352 are vertically aligned, and the two hooks are set opposite each other, which can prevent the clamp from disengaging from the lower connector 12 and the corresponding upper connector 11 during the clamping process; the lower vertical bar 321 and the upper vertical bar 351 are slidably connected in the Z direction, which is the axial direction of the lower connector 12 and the upper connector 11 during the docking process. Therefore, the lower vertical bar 321 and the upper vertical bar 351 can complete the axial docking of the lower connector 12 and the corresponding upper connector 11 smoothly in the Z direction.

[0074] The sliding connection between the upper vertical rod 351 and the lower vertical rod 321 is achieved as follows: the lower end of the upper vertical rod 351 is provided with an upwardly extending recessed groove 353; the groove 353 connects the inner and outer sides of the upper vertical rod 351, and parallel Z-axis slide rails are provided on its opposite side walls; the lower vertical rod 321 is located in the groove 353 and is slidably connected to the two Z-axis slide rails through the Z-axis protrusions on its opposite sides, thereby realizing the sliding connection between the upper vertical rod 351 and the lower vertical rod 321.

[0075] The upper handle 31 is a straight rod with its length along the Y direction. One end of the upper handle 31 is fixedly connected to the outside of the lower vertical rod 321, and the other end is used for hand gripping. The lower handle 36 is a curved rod with its middle part bent towards the middle of the upper handle 31. The lower handle 36 is located below the upper handle 31 and outside the upper vertical rod 351. The curved part of the lower handle 36 is hinged to the upper handle 31. One end of the lower handle 36 is hinged to the upper vertical rod 351, and the other end is used for hand gripping.

[0076] The hinge method of the lower handle 36 and the upper handle 31 is as follows: a protrusion 313 is provided on the lower part of the middle of the upper handle 31; an oblong hole in the Y direction is provided on the protrusion 313; the oblong hole passes through the protrusion 313 in the X direction, and a pin 37 is rotatably inserted inside it. The pin 37 can slide in the oblong hole to avoid jamming; a connecting plate 361 is provided on each of the two side walls in the X direction at the bend of the lower handle 36. The two connecting plates 361 are parallel to each other, and the two connecting plates 361 are fixed to the two ends of the pin 37 respectively, thereby realizing the hinge of the lower handle 36 and the upper handle 31.

[0077] The hinge connection between the lower handle 36 and the upper vertical rod 351 is as follows: one end of the lower handle 36 is provided with a groove, and round holes are provided on both sides of the groove. The round holes are rotated and engaged with the cylinders on both sides of the upper vertical rod 351, thereby realizing the hinge connection between the lower handle 36 and the upper vertical rod 351.

[0078] When one end of the upper handle 31 and the lower handle 36 is close to each other, the other ends (i.e., the hand-held ends) are far apart; conversely, when the other ends of the upper handle 31 and the lower handle 36 are close to each other, one end of the two handles is far apart. Since the upper handle 31 is fixedly connected to the lower side clamp 32 and the lower handle 36 is hinged to the upper side clamp 35, when one end of the upper handle 31 and the lower handle 36 is far apart, the upper side clamp 35 and the lower side clamp 32 are close to each other, that is, the distance between the upper crossbar 352 and the lower crossbar 322 is reduced, that is, the jaws of the clamps are reduced. When in use, the upper side clamp 35 hooks the upper end of the lower connector 12 and the lower side clamp 32 hooks the lower end of the corresponding upper connector 11. By reducing the jaws, the lower connector 12 and the corresponding upper connector 11 can be axially connected.

[0079] Furthermore, in order to maintain the axial positional relationship between the lower connector 12 and the corresponding upper connector 11 for a long period of time after they are axially aligned, the clamp in this embodiment is also equipped with a one-way check ratchet 41 and a pawl 42; as Figure 4 As shown, the upper handle 31 has a handle through hole 311 and a handle groove 312 connected to each other along the Y direction; one end of the one-way check ratchet 41 is fixedly connected to the lower handle 36, and the other end extends into the handle through hole 311, with a gap between it and the side wall of the handle through hole 311, and its check teeth face the handle groove 312; the pawl 42 is located in the handle groove 312, and its working end corresponds to the check teeth of the one-way check ratchet 41; a compression spring 43 is provided between the pawl 42 and the side wall of the handle groove 312; the compression direction of the compression spring 43 is the Y direction. A cover plate 44 is provided outside the upper end of the handle groove 312; the cover plate 44 is detachably connected to the upper handle 31 by screws to prevent the compression spring 43 and the pawl 42 from coming out of the handle groove 312; the pawl 42 is provided with a cylindrical pawl handle 421; the pawl handle 421 is axially arranged along the Z direction, its lower end is perpendicularly connected to the pawl 42, and its upper end extends out of the cover plate 44 from the side of the cover plate 44 near the one-way check ratchet 41, so that the pawl 42 can be controlled to move along the Y direction through the pawl handle 421 to compress the compression spring 43.

[0080] Therefore, as the handles of the upper handle 31 and lower handle 36 move closer together to clamp the lower connector 12 and the corresponding upper connector 11, the pawl 42, under the action of the compression spring 43, sequentially engages with each check tooth on the one-way check ratchet 41 until the lower connector 12 and the corresponding upper connector 11 are properly aligned. At this point, the pawl 42 engages with a corresponding check tooth to prevent the one-way check ratchet 41 from moving in the opposite direction, thus ensuring the axial position of the lower connector 12 and the corresponding upper connector 11 is fixed. After use, the pawl handle 421 can be manually retracted to move the pawl 42 away from the one-way check ratchet 41, thereby releasing the fixed state between the upper handle 31 and lower handle 36 and facilitating the removal of the clamps from the corresponding lower connector 12 and upper connector 11.

[0081] However, different sensor brackets have different outer diameters. To accommodate sensor brackets of different sizes, the clamping mechanism 3 of the docking device in this embodiment is also provided with an adjustment assembly that is rotatably connected to the clamp and movably connected to the U-shaped bracket 2. The adjustment assembly includes a moving screw 33 arranged along the Y direction in the length direction and a screw wrench 34. The moving screw 33 is located above the upper handle 31, and one end of it is provided with a ball head. The ball head cooperates with a ball seat provided on the outer side wall of the lower vertical rod 321 to achieve a rotatable connection. The middle part of it is threadedly connected to the corresponding parallel arm 21 of the U-shaped bracket 2, and the other end of it extends out of the corresponding parallel arm 21. The other end of the moving screw 33 is hexagonal prism-shaped. The screw wrench 34 is a hexagonal wrench. The screw wrench 34 of the hexagonal wrench is detachably installed on the hexagonal prism-shaped end of the moving screw 33 for rotating the moving screw 33. Rotating the moving screw 33 by the screw wrench 34 causes the clamp to move along its own axis, which can change the relative position of the clamp and the corresponding parallel arm 21 of the U-shaped bracket 2. At the same time, rotating the moving screws 33 on both sides of the sensor bracket 1 to be docked will change the position between the two clamps' working ends, thus adapting to sensor brackets with different outer diameters to be docked, increasing the applicability of the docking device.

[0082] The circumferential docking unit is mounted on the U-shaped bracket 2, and its working end corresponds to one of the steel bars 13 of the sensor bracket 1 to be docked, for rotating the sensor bracket 1 to be docked corresponding to the steel bar 13. Specifically, the circumferential docking unit includes a sliding base 51 fitted outside the U-shaped base 22 of the U-shaped bracket, a rotating base 52 rotatably mounted above the sliding base 51 via a base pivot, a rack and pinion rod 53 with a clearance fit inside the rotating base 52, a pivot installed inside the rotating base 52 and rotatably connected to the rotating base 52, a gear sleeved outside the pivot and meshing with the rack and pinion rod 53, and a rotating handle 54 connected to one end of the pivot. The base shaft between the rotating base 52 and the sliding base 51 extends into the sliding base 51; the sliding base 51 is threaded with a first set screw 511 and a second set screw 512, the working end of the first set screw 511 corresponds to the side wall of the U-shaped bottom 22; the working end of the second set screw 512 corresponds to the base shaft; both ends of the rack push rod 53 are triangular wedges, used to contact the side wall of the steel strip 13 of the sensor bracket 1 to be docked.

[0083] In use, the sliding base 51 is moved along the U-shaped bottom 22 of the U-shaped bracket, and the rotating base 52 is rotated so that one end of the rack push rod 53 contacts the side wall of one of the steel bars 13 on the lower connector 12 to be docked. Then, the relative position of the sliding base 51 and the U-shaped bottom 22 is locked by the first set screw 511, and the relative position between the rotating base 52 and the sliding base 51 is locked by the second set screw 512. Then, the rotating handle 54 is used to rotate the shaft inside the rotating base 52, which in turn rotates the gear inside the rotating base 52. The gear drives the rack push rod 53 to move, and the rack push rod 53 provides a thrust to the corresponding steel bar 13, thereby pushing the lower connector 12 connected to the steel bar 13 to rotate around the corresponding upper connector 11, correcting the circumferential misalignment of the two sections of the sensor bracket to be docked, and realizing the precise circumferential docking of the lower connector 12 and the corresponding upper connector 11. If it is necessary to rotate the sensor bracket to be docked in the opposite direction, rotate the rotating base 52 again and adjust the position of the sliding base 51 so that the other end of the rack push rod 53 abuts against the steel bar 13, pushing the sensor bracket to be docked to rotate in the opposite direction.

[0084] In actual rotation, the lower connector 12 usually does not rotate with the corresponding upper connector 11, so the lower connector 12 and the corresponding upper connector 11 can be easily and accurately circumferentially connected. However, sometimes the lower connector 12 may rotate slightly with the corresponding upper connector 11 under the action of friction. At this time, the two can also be accurately connected circumferentially with slight manual assistance, which greatly improves the safety factor compared to relying entirely on manual connection.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
