Abstract
Description
Technical Field
[0001] This invention belongs to the field of dental medical equipment, specifically relating to a torque controller bracket and a torque controller. Background Technology
[0002] Currently, dental implant technology is developing rapidly and is widely accepted. Dental implantation involves surgically inserting dental implants into the alveolar bone of the upper and lower jaws at the site of the missing tooth, providing fixation and support for prostheses or other restorations. During the implantation process, it is crucial to control the torque appropriately. If the torque does not reach the predetermined value, unstable implantation may occur; conversely, excessive torque may cause excessive pressure on the surrounding bone, leading to implant failure and failure to integrate with the surrounding bone. Therefore, the industry needs a dental wrench that allows dentists to understand the torque level and adjust it accordingly.
[0003] A dental implant wrench disclosed in patent CN216985217U includes a main body module, a steering module, and an actuation module. The main body module includes a housing assembly, a connecting block rotatably connected to one end of the housing assembly, and a torque pin assembly disposed inside the connecting block. The steering module includes a first connecting component disposed within the cavity of the housing assembly, passing through the connecting block and engaging with the surface of the torque pin assembly, a second connecting component connected to one end of the first connecting component, and a rotating component connected to one end of the second connecting component and extending to the outside of the housing assembly. The actuation module is disposed on the surface of the housing assembly, allowing the user to operate freely in the confined space of the oral cavity. The user can visually observe the torque value on the ruler frame, control the torque within a suitable range, ensure a stable implantation procedure, protect the patient's gums, improve the efficiency of the implantation procedure, and enhance the overall implantation outcome.
[0004] In actual operation, the main module will swing as the lever bends. If you support the main module by hand, it will cause a deviation in the torque generated. Therefore, the entire force point of the torque wrench is on the lever. When applying pressure to the lever, due to the weight of the device itself and the direction of the force, the lever is very easy to bend longitudinally, thus losing the true reading of the torque wrench. Summary of the Invention
[0005] The purpose of this invention is to address the above-mentioned problems by providing a torque controller bracket and a torque controller that can solve the aforementioned technical problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solutions:
[0007] A torque controller bracket includes a bracket rod. One end of the bracket rod is provided with a limit scale, and the other end of the bracket rod is provided with a torsion column. A spring plate is vertically provided on the side of the bracket rod. One end of the spring plate is connected to the torsion column, and the other end of the spring plate is twisted and passes through the limit scale. The limit scale is provided with a graduated abutment surface. The twisted end of the spring plate abuts against the graduated abutment surface under its own elastic force.
[0008] In the torque controller bracket, the spring plate includes a curved part and a scale part. One end of the curved part, which is perpendicular to the bracket rod, is connected to the torsion column. The other end of the curved part is connected to the scale part after being twisted by 90°. The scale part is inserted into the limiting scale and abuts against the scale abutment surface.
[0009] In the torque controller bracket, a limiting groove is provided in the limiting scale, the scale part passes through the limiting groove, and a force-applying handle is provided at one end of the scale part passing through the limiting groove.
[0010] In the torque controller bracket, a slot is radially provided on the torsion column that is offset from the scale abutment surface. One end of the curved part is disposed in the slot, and the scale part is in contact with the scale abutment surface to make the curved part bend.
[0011] In the torque controller bracket, the scale portion has a protrusion that abuts against the scale abutment surface, causing the curved portion to be curved.
[0012] In the torque controller bracket, the limiting scale includes a first limiting surface and a second limiting surface. The first limiting surface is disposed on the bracket rod on the same side as the torsion column, and the second limiting surface is connected to the first limiting surface through a scale abutment surface.
[0013] In the torque controller bracket, the spring plate passes between the first limiting surface and the second limiting surface, the first limiting surface is in contact with the portion of the spring plate near the torsion column, and the second limiting surface is in contact with the portion of the spring plate away from the torsion column.
[0014] The present invention also provides a torque controller, including a wrench, the torque controller including the torque controller bracket, and a snap-fit assembly provided on the other side of the bracket rod opposite to the spring plate, the wrench being snapped onto the snap-fit assembly.
[0015] In the torque controller, the locking assembly includes a positioning groove and a locking claw. The positioning groove is located on the same end of the support rod as the torsion column. The positioning groove is engaged with the blade connection side of the wrench. The locking claw is clamped on the handle side of the wrench.
[0016] In the torque controller, the locking claw extends from both sides of the support rod and surrounds the handle of the wrench. The locking claw is provided with a spring arm, which is engaged in the axial groove of the wrench handle.
[0017] The advantages of this invention are:
[0018] The elastic element that generates torque uses a flat, elongated spring plate, which is horizontally and vertically connected to the support rod. This allows the spring plate to bend and deform in the horizontal direction to provide the rated torque, while preventing the spring plate from collapsing and deforming in the longitudinal direction, thus accurately displaying the torque provided by the spring plate.
[0019] By setting a torsion column and adding a protrusion to the scale section, the spring plate bends when it comes into contact with the scale surface. The torque generated by the bending allows the scale section to return to the zero mark position after use, preventing reading errors caused by the spring plate failing to return to its original position after repeated use.

[0023] In the diagram, the components are: support rod 1, torsion column 11, limit scale 2, scale abutment surface 21, first limit surface 22, second limit surface 23, spring plate 3, bending part 31, scale part 32, force application handle 33, wrench 4, snap-fit assembly 5, positioning groove 51, snap-fit claw 52, spring arm 53, and protrusion 54. Detailed Implementation
[0024] The following are specific embodiments of the invention, which are described in conjunction with the accompanying drawings. The technical solution of the invention will be further described, but the invention is not limited to these embodiments.
[0025] Example 1
[0026] like Figure 2As shown, the torque controller bracket includes a bracket rod 1. One end of the bracket rod 1 is provided with a limit scale 2, and the other end of the bracket rod 1 is provided with a torsion column 11. A spring plate 3 is vertically provided on the side of the bracket rod 1. One end of the spring plate 3 is connected to the torsion column 11, and the other end of the spring plate 3 is twisted and inserted into the limit scale 2. The limit scale 2 is provided with a scale abutment surface 21. The twisted end of the spring plate 3 abuts against the scale abutment surface 21 under its own elastic force.
[0027] That is, a flat, elongated spring plate 3 is horizontally and vertically connected to the support rod 1 to replace the spring column of a conventional torque controller. Torque is provided by bending the spring plate 3 in the horizontal direction. The upright spring plate 3 can prevent longitudinal deformation caused by gravity or force deviation during use, so that the torque generated by the spring plate 3 can accurately correspond to the displayed reading.
[0028] Furthermore, by setting the installation angle of the torsion end of the spring plate 3 and the torsion column 11, bending occurs when the torsion end is in contact with the scale abutment surface 21, causing the torsion end of the spring plate 3 to generate an elastic force that moves towards the scale abutment surface 21, thus preventing the spring plate 3 from failing to return to the zero scale position after repeated use.
[0029] In this embodiment, the spring plate 3 includes a bent portion 31 and a scale portion 32. One end of the bent portion 31, which is perpendicular to the support rod 1, is connected to the torsion column 11. The other end of the bent portion 31 is connected to the scale portion 32 after being twisted by 90°. The scale portion 32 passes through the limiting scale 2 and abuts against the scale abutment surface 21.
[0030] The spring plate 3 has a scale portion 32 that is twisted 90° and parallel to the support rod 1 on the side near the limit scale 2. The remaining part is a bent portion 31 that is perpendicular to the support rod 1. Both the scale portion 32 and the bent portion 31 can maintain their inherent shape well when subjected to force in the long side direction. Therefore, the bent portion 31 can avoid interference from longitudinal force and bend only horizontally. The scale portion 32 can also maintain its stability when it is in lateral contact with the scale abutment surface 21.
[0031] In this embodiment, a limiting groove is provided in the limiting scale 2, the scale part 32 passes through the limiting groove, and a force-applying handle 33 is provided at one end of the scale part 32 passing through the limiting groove.
[0032] The limiting groove is a flat, elongated guide slot on the support rod 1. The groove width is approximately equal to the thickness of the spring plate 3, serving as longitudinal support and a guide for the scale part 32 to swing around the torsion column 11. A force-applying handle 33 is installed at one end of the spring plate 3 that passes through the limiting groove for the user to hold.
[0033] Preferably, the torsion column 11 has a slot that is radially offset from the scale abutment surface 21, one end of the curved part 31 is disposed in the slot, and the scale part 32 is in contact with the scale abutment surface 21 so that the curved part 31 is curved.
[0034] A mounting slot for the spring plate 3 is provided on the torsion column 11. The end of the spring plate 3 is inserted into the slot and then secured with bolts perpendicular to the surface of the spring plate 3, thus completely fixing the spatial position of the spring plate 3 relative to the support rod 1. At this time, the mounting slot is intentionally rotated at a certain angle to form a misalignment with the scale abutment surface 21. When the spring plate 3 is installed in the slot, it will force the spring plate 3 against the scale abutment surface 21 to bend, thereby giving the scale part 32 an elastic force to move closer to the scale abutment surface 21.
[0035] The mounting slot can also be offset from the scale abutment surface 21, causing the spring plate 3 to bend.
[0036] Preferably, the scale portion 32 is provided with a protrusion that abuts against the scale abutment surface 21, causing the curved portion 31 to be curved.
[0037] The originally upright curved part 31 of the spring plate 3 is twisted by 90° to become a flat scale part 32. Therefore, the horizontal width increases and a protrusion is formed towards the scale abutment surface 21. Under the pressure of the protrusion, the curved part 31 deviates from the original angle and produces an arc bend. At this time, the spring part 31 will generate a rebound force on the scale part 32, so that the protrusion of the scale part 32 is close to the scale abutment surface 21, ensuring that the spring plate 3 can return to the zero scale position after use.
[0038] In this embodiment, the limiting scale 2 includes a first limiting surface 22 and a second limiting surface 23. The first limiting surface 22 is disposed on the support rod 1 on the same side as the torsion column 11, and the second limiting surface 23 is connected to the first limiting surface 22 through the scale abutment surface 21.
[0039] The torsion column 11, spring plate 3 and limit scale 2 are all set on the other side of the fixed wrench 4, and the spring plate 3 is aligned vertically with the wrench 4. At the same time, the torsion column 11 can be as close as possible to the position of the wrench 4 cutter head slot, so that the torque generated by the spring plate 3 can be transmitted to the wrench 4 more directly and efficiently, reducing the difficulty of calibrating the scale reading of the spring plate 3.
[0040] Preferably, the spring plate 3 passes between the first limiting surface 22 and the second limiting surface 23, with the first limiting surface 22 contacting the portion of the spring plate 3 near the torsion column 11 and the second limiting surface 23 contacting the portion of the spring plate 3 away from the torsion column 11.
[0041] The first limiting surface 22 and the second limiting surface 23 respectively restrict the upper and lower surfaces of the flat scale part 32, so that the scale part 32 will not wobble up and down when it moves with the bending part 31. Furthermore, the first limiting surface 22 and the second limiting surface 23 are distributed front and back, so that the torsion column 11, the first limiting surface 22 and the second limiting surface 23 form three limiting fulcrums in sequence, which strengthens the restriction on the longitudinal movement of the spring plate 3, reduces the influence of other deformations of the spring plate 3 on the torque reading, and makes the torque controller easier to operate.
[0042] In addition, the torsion column 11 and the spring plate 3 are detachable structures that are easy to replace. However, the first limiting surface 22 and the second limiting surface 23 are only separated by the thickness of the spring plate 3. Neither the torsion section nor the force-applying handle 33 of the spring plate 3 can pass through, so the spring plate 3 cannot be removed from the support rod 1. Therefore, the staggered arrangement of the first limiting surface 22 and the second limiting surface 23 also serves to avoid the spring plate 3 during disassembly and assembly.
[0043] Example 2
[0044] like Figure 1 and Figure 3 As shown, the torque controller bracket is used in the torque controller. A snap-fit assembly 5 is provided on the other side of the bracket rod 1 relative to the spring plate 3, and the wrench 4 is snapped onto the snap-fit assembly 5.
[0045] In this embodiment, the snap-fit assembly 5 includes a positioning groove 51 and a snap-fit claw 52. The positioning groove 51 is located on the same end of the support rod 1 and the torsion column 11. The positioning groove 51 is engaged with the blade connection side of the wrench 4. The snap-fit claw 52 is clamped on the handle side of the wrench 4.
[0046] That is, the wrench 4 is fixed at two points by using the positioning groove 51 to restrict the wrench 4 from approaching the blade slot and the locking claw 52 to lock the wrench 4 handle side. The detachable design makes it easier to use the wrench 4 alone, reduces the impact on the patient's oral cavity, and makes the operation more flexible.
[0047] The positioning groove 51 has a polygonal shape, and the wrench 4 also has a recessed polygonal column on the side near the blade head slot that matches the positioning groove 51. This is mainly used to limit the direction and circumferential angle of the wrench head. The handle of the wrench 4 has raised and recessed anti-slip textures, and the locking claw 52 uses the anti-slip textures to clamp and fix it.
[0048] Preferably, the locking claw 52 extends from both sides of the support rod 1 and surrounds the handle of the wrench 4. The locking claw 52 is provided with a spring arm 53, which is engaged in the groove of the handle of the wrench 4.
[0049] The locking claw 52 forms a semi-enclosed "C" shape, and the handle part of the wrench 4 fits into it with a gap. Due to the axial concave grooves on the handle part, its circumferential surface forms a concave-convex profile. The handle part of the wrench 4 is stabilized by the abutting of the protruding surface against the inner walls on both sides of the locking claw 52.
[0050] Considering that the user needs to apply a certain pressure to the support rod 1 to make the screwdriver head hold the screw, the two ends of the positioning groove 51, the screwdriver head slot of the wrench 4 and the handle form the two ends of the lever. When applying force, the handle may fall off the locking claw 52. Therefore, a U-shaped hollow is opened on the locking claw 52 to form a spring arm 53. An arc-shaped or barbed protrusion is set on the inner side of the end of the spring arm 53. The elasticity of the spring arm 53 material itself is used to lock the arc-shaped or barbed protrusion 54 into the axial concave groove on the handle of the wrench 4, further ensuring the fixing effect of the locking claw 52 on the wrench 4.
[0051] In addition, the end of the spring arm 53 is provided with an arc-shaped meandering part that continues to extend around the handle of the wrench 4 to the claw mouth of the locking claw 52, forming a greater than 180° encirclement with the locking claw 52 to clamp the wrench 4 in the encirclement.
[0052] The spring arm 53 can be a single arm or multiple arms on the same side. In this case, the end of the spring arm 53 will be more curved inward than the locking claw 52, so that the end protrusion is embedded into the axial concave groove of the wrench 4, while pushing the handle of the wrench 4 against the inner wall of the locking claw 52 on the other side. Alternatively, one or more sets of spring arms 53 can be provided on each side of the locking claw 52, so that the end protrusions of the spring arms 53 on both sides are simultaneously embedded in the axial concave groove of the wrench 4, so that the handle of the wrench 4 is in a neutral position within the locking claw 52, ensuring that the wrench 4 can be stably fixed in the locking claw 52.
[0053] When using the device, first insert the dedicated screwdriver bit into the ratchet slot of the wrench 4. Use the wrench 4 alone to turn the screw. Before tightening, install the torque controller onto the wrench 4. After aligning the screwdriver bit with the screw, hold the force-applying handle 33 on the opposite side and turn the spring plate 3 to the desired torque setting. Under the action of the spring force, the wrench 4 continues to rotate until the screw is tightened. During the tightening process, simply hold the force-applying handle 33; there is no need to support the support rod 1 to ensure the stability of the entire device.
[0054] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
