Description
Technical Field
The invention relates to a conical spiral spring and a spinning wheel type fishing line wheel with the same.
Background
The spring is a common mechanical part which works by utilizing elasticity, and the application field of the spring is very wide. If the adjusting button component is applied to the spinning type fishing line wheel and used for adjusting the braking force, the adjusting button component comprises a nut which is in threaded connection with the top of a main shaft, an adjusting button which is fixed with the nut, a spring which is sleeved on the main shaft and a button seat which can only move along the axial direction of the main shaft, two ends of the spring are abutted between the nut and one end of the button seat, and the other end of the button seat is abutted with a brake pad group which is arranged in an inner cavity of the line wheel. When the fishing reel is used, the adjusting button is rotated to drive the nut to rotate, the nut simultaneously moves to the side of the button seat along the axial direction of the main shaft and presses the spring, the elastic force generated by the pressed spring is transmitted to the brake sheet assembly through the button seat, and after the brake sheet assembly is pressed, the friction force of the reel rotating around the main shaft is increased, so that the line outgoing force of the fishing line wound on the reel is also increased; on the contrary, the generated braking force is smaller, so as to achieve the purpose of adjusting the braking force.
Conventionally, a cylindrical coil spring in which a wire rod having a circular cross section is bent into a spiral shape is often used as the spring, and the spring has a structure disclosed in documents with application publication numbers CN110384079A and CN 101461353A. There is also a cylindrical coil spring which rotates a wire rod which is axially concave-convex into a continuous corrugated shape; or a cylindrical coil spring formed by spirally bending a wire rod having a rectangular cross section, such as several spring structures disclosed in chinese patent No. CN 103843738B.
In the spring having the above-described structure, although the spring can expand and contract in the axial direction and transmits the axial force of the adjuster knob to the brake pad assembly, it has been found in practical use that such a cylindrical coil spring (regardless of whether the wire has a circular, rectangular, or concave-convex cross section) is highly likely to bend in the radial direction due to the circumferential friction force when the adjuster knob is compressed by rotation, i.e., the spring is likely to deform by buckling.
The conventional conical coil spring has better stability than the cylindrical coil spring, but is not suitable for use in a spinning reel because the characteristic line of the conical coil spring immediately after the first turn (counted from the large end) is nonlinear, that is, the conical coil spring is mostly nonlinear in the entire compression process. In addition, in a natural state, adjacent coils of the conical coil spring are separated from each other, and when the conical coil spring is compressed, the conical coil spring may be bent in a radial direction.
Meanwhile, the prior spinning reel has the following problems:
in the above-mentioned adjusting knob assembly, in order to make the knob seat only move axially (the purpose of axial movement is that on one hand, the brake assembly can be pushed axially, on the other hand, a click assembly can be set between the adjusting knob and the knob seat, so that when the adjusting knob is rotated, it can produce click sound), the knob seat and main shaft are matched with non-circular hole and flat shaft, for example, the structure disclosed in the publication No. CN101461353A, i.e. the middle of the knob seat is equipped with non-circular hole, and as the position of reference number 66c on the attached figure 9 in said publication, it is generally a square hole, also called flat hole; the end of the main shaft needs to be designed into a flat shaft structure (usually, two sides of the end of the main shaft are milled to form parallel surfaces, see the part indicated by the reference number 15a on fig. 8, after a part of the surfaces are milled away), and in order to match with a nut, an external thread is further processed on the circular arc peripheral surface of the flat shaft structure of the main shaft (see the part indicated by the reference number 15b on fig. 8 in the document). But in use it was found that: because the main shaft is long and narrow, the strength of the main shaft can be weakened by milling the long section of the end part of the main shaft. Therefore, when the adjusting button is rotated at the end part of the main shaft, the thread of the main shaft is abraded, and the nut matched with the main shaft idles, so that the function of adjusting the braking force of the adjusting button is invalid. And the square hole on the knob seat can become a round hole due to abrasion after a long time of use, so that the square hole can rotate relative to the main shaft, and the click sound is not generated when the adjusting knob is rotated, thereby influencing the operation hand feeling.
Disclosure of Invention
The first technical problem to be solved by the present invention is to provide a conical coil spring which is not easy to generate radial distortion and has a long linearization characteristic, in view of the current state of the prior art.
The second technical problem to be solved by the invention is to provide a spinning reel which is not easy to generate radial distortion and can meet the linearization of brake performance aiming at the current situation of the prior art.
The technical scheme adopted by the invention for solving the first technical problem is as follows: a conical coil spring formed by bending a wire rod having a rectangular cross section into a spiral shape and having a large end and a small end, characterized in that: the height of the rectangular section of the wire is larger than the width, and the end faces of the large end and the small end of the conical spiral spring are designed into planes; the conical coil springs are partially overlapped in the axial direction between the adjacent spring rings in a natural state; in the adjacent spring rings, the small spring ring is located in the large spring ring, and the end faces of the spring rings are flush with each other.
For convenience of design and processing, the conical spiral spring is a conical spiral spring with a constant pitch.
In the above aspect, it is preferable that the ratio of the height to the width of the rectangular cross section of the wire rod is (2.5-3): 1, such that after the spring is axially compressed, each spring turn has sufficient distance to slide along the outer spring turn. If the ratio of the height to the width of the rectangular cross-section of the wire is too small, the axial sliding distance of each spring turn is shorter and the variation between the spring force and the corresponding axial compression displacement tends to be more non-linear. If the ratio of the height to the width of the rectangular section of the wire is too large, when the wire is applied to the field (such as the below-mentioned spinning reel) with limited axial space, the number of turns of the spring cannot be too much, so that the spring is soft, the spring force is small, and the requirement of the use occasion on the spring force cannot be met.
In the above aspect, it is preferable that the ratio of the height of the partial overlap between adjacent coils in the axial direction to the height of the rectangular cross section is 1: (4.8.0-5.2). The proportion can ensure that the spring is not easily deformed axially after being axially pressed, and can also meet the requirement of the axial movement amount of each spring ring, so that the required relationship of approximately linear change between the axial displacement amount and the spring force can be met after the spring is completely tightened axially.
The technical scheme adopted by the invention for solving the second technical problem is as follows: the utility model provides a spinning wheel formula fish tape wheel, includes the main part of fish tape wheel, installs the rocking arm subassembly of main part one side, supports the cavity ratch in the main part, cartridge main shaft in the ratch, install epaxial line wheel, install on the ratch and be used for coiling the fishing line on the line wheel line shell, be located the brake block group of line wheel inner chamber and connect the adjusting button subassembly that the tip is used for adjusting brake force size before the main shaft, adjusting button subassembly is including threaded connection again in the screw thread section of main shaft tip, the adjusting button of fixing mutually with the nut and suit at epaxial spring of main shaft and can follow the button seat of main shaft axial displacement, the both ends of spring support between the one end of nut and button seat, the other end of button seat offsets with the terminal surface of the key china department in the brake block group, its characterized in that: the spring is formed by bending a wire rod with a rectangular cross section into a spiral shape to form a conical spiral spring with a large end and a small end, the height of the rectangular cross section of the wire rod of the spring is larger than the width of the rectangular cross section of the wire rod of the spring, and the end surfaces of the large end and the small end of the spring are designed into planes; the springs are partially overlapped in the axial direction between the adjacent spring rings in a natural state; in the spring in the completely compressed state, the small spring ring is located in the large spring ring and the end faces of the spring rings are flush.
In the above spinning reel, the ratio of the height to the width of the rectangular cross section of the wire rod is preferably (2.5-3): 1, the spring has enough turns to be pressed in a small space of the adjusting button assembly, so that the linear relation required by the fishing reel can be met between the spring force required by adjusting the braking force and the axial displacement of the spring, and the spring force with the required magnitude can be provided.
In the above spinning reel, it is also preferable that the ratio of the height of the partial overlap between the adjacent coils in the axial direction to the height of the rectangular cross section is 1: (4.8.0-5.2), when the ratio is too large, i.e. the overlapping height is too large, the number of turns of the spring will be larger and the inner diameter of the small end of the conical spring will be smaller under the condition of the free height of the spring, thus the assembly of the part (such as the nut or the spring seat in the figure) in the inner hole of the spring will be affected.
In the spinning wheel type fishing line wheel of each proposal, the section of the threaded section of the main shaft is circular, and two sides of the main shaft adjacent to the threaded section are respectively provided with a plane to form a non-circular section; the middle part of the button seat is provided with a first round hole through which a threaded section of the main shaft can pass; the key washer comprises a main washer with a second round hole in the middle and an auxiliary washer which is located in a limiting groove on the end surface of the main washer and can rotate together, the middle of the auxiliary washer is provided with a special-shaped hole, the special-shaped hole consists of a third round hole and a long hole which are communicated with each other, the second round hole and the third round hole can be penetrated by a threaded section of the main shaft, and a non-circular section of the main shaft can slide into the long hole from the third round hole; and meanwhile, a positioning groove and a positioning column which are matched and connected with each other are arranged at the other end of the button seat and the end surface of the main washer.
In the spinning wheel type fishing line reel, it is more practical that the limiting groove is internally provided with a magnet which is attracted with the auxiliary washer, so that the auxiliary washer and the main washer can be quickly combined together.
In the above scheme, preferably, the positioning column is arranged at the other end of the knob seat, and the positioning groove is located on the end surface of the main washer.
Compared with the prior art, the invention fully utilizes the characteristic of good stability of the existing conical spiral spring, and the partial overlap in the axial direction between the adjacent spring rings in a natural state is utilized, so that each spring ring of the spring can slide depending on the spring ring at the outer layer when being axially pressed and slid, radial deformation is not easy to occur, and meanwhile, the characteristic that the height of the rectangular section of the wire rod is larger than the width is utilized to prolong the axial sliding displacement of each spring ring, namely, the linear characteristic of the corresponding spring ring is lengthened. When the spring is applied to the spinning type fishing line wheel, the requirement on the braking force of the existing spinning type fishing line wheel is not very large, so that the spring can just meet the requirement on the linearization of the braking force of the spinning type fishing line wheel, and simultaneously, the defect caused by the torsional deformation of the spring can be well overcome.
Secondly, because the section of the threaded section of the main shaft is changed from the existing non-circular shape to the circular shape, and the non-circular section is only matched with the long hole of the auxiliary washer, the axial length of the non-circular section is very short, thereby effectively ensuring the strength of the main shaft on one hand, and ensuring the continuity of the threads of the threaded section on the other hand, so that the rotation of the adjusting button is more smooth. Meanwhile, the knob seat is changed from a non-circular hole into a circular hole (namely a first circular hole) to be matched with the spindle, so that the defect caused by abrasion of a square hole in the prior art is not needed to be considered, the requirement that the knob seat and the key washer can only axially move relative to the spindle is met by means of the matching of the auxiliary washer and the main washer and the matching of a special-shaped hole in the auxiliary washer and the spindle ingeniously, and meanwhile, the assembly requirement can be met.

Detailed Description

The adjusting button assembly 8 includes a nut 81 screwed on the threaded section 41 at the front end of the main shaft 4, an adjusting button 82 fixed with the nut, a spring 83 sleeved on the main shaft 4, and a button seat 84 capable of moving along the axial direction of the main shaft (see fig. 2 and fig. 3), two ends of the spring 83 are abutted between the nut 81 and one end of the button seat 84, and the other end of the button seat 84 is abutted with one end surface of a key washer in the brake pad set. One end of the knob seat 84 is sleeved with a connecting sleeve 85, the connecting sleeve 85 is mounted on the adjusting knob 82 through two screws, so that the knob seat 84 is limited on the adjusting knob 82 and can have a certain axial movement amount relative to the adjusting knob 82, and under the action of the spring 83, the knob seat always has a tendency of moving away from the adjusting knob 82. Meanwhile, a conventional click member 86 is provided between the knob seat 84 and the adjustment knob 82, and when the adjustment knob is rotated, a clear click sound is generated by the click member 86 to indicate that the angler is performing the force adjustment operation. Meanwhile, the middle part of the button seat 84 is also sleeved with a sealing sheet 87, and the sealing sheet 87 is matched with the inner wall of the front cavity of the wire wheel 5 to seal the front cavity so as to improve the waterproof performance of the front cavity. In order to prevent the spring 83 from being twisted due to a large frictional force, a slide piece 88 having a smaller coefficient of friction than the button seat is provided between the spring 83 and the button seat 84. The connection between the knob seat 84 and the adjusting knob 82, the click assembly 86 and the sealing plate 87 fitted on the knob seat are all the prior art, and the structure is described in the document with the application publication number CN 110384079A.
In the present embodiment, the main improvement of the above-mentioned knob assembly 8 is a spring 83, the spring 83 is a constant pitch conical helical spring formed by bending a wire material with a rectangular cross section into a helical shape, wherein the height h1 of the rectangular cross section of the wire material (i.e. along the axial direction of the spring) is larger than the width b (i.e. along the radial direction of the spring), and the end faces of the large end and the small end of the spring are both designed to be flat (i.e. in a horizontal state); the springs 83 are partially overlapped in the axial direction between the adjacent coils in a natural state (see fig. 5 and 6); in the axially fully compressed state of the spring 83, the smaller of the adjacent turns is seated in the larger turn, with the end faces of the turns being flush (see fig. 4 and 12).
Through a plurality of tests, the ratio of the height h1 to the width b of the rectangular section of the spring wire is preferably (2.5-3): in this embodiment, the rectangular cross-section of the wire has a height H1 of 2mm and a width b of 0.7mm, the ratio of the height H1 to the width b is about 2.86, the ratio is right-handed (or left-handed, of course), the effective number of turns of the spring is selected to be 3, and the axial height H of the spring is 5.2 mm. The ratio of the height h2 of the partial overlap between adjacent coils in the axial direction to the height h1 of the rectangular cross section is preferably 1: (4.8.0-5.2) with an overlap height h2 of 0.40mm, in a ratio of 1 to the height h1 of the rectangular section: 5.0.
the spring 83 is placed on a testing machine (e.g., a spring compression force measuring instrument) which is provided with a position sensor capable of detecting the compression amount of the spring 83 and a force sensor for applying force to the spring, and the spring 83 is gradually compressed along with the downward movement of a pressure head 100 on the testing machine until the state shown in fig. 12 is reached, namely, the small spring ring in the adjacent spring is located in the large spring ring at the moment, the end surfaces of the spring rings are level with each other, and the force applied to the spring 83 is the largest at the moment. The relation chart of fig. 13 is drawn from the data obtained by the position sensor and the force sensor on the testing machine, and as can be seen from fig. 13, when the stress of the spring is less than 0.1KN, the stress and the compression amount of the spring are basically in a straight line, and the braking force of the spinning reel is generally less than 0.1KN, therefore, the conical spiral spring can meet the requirement that the braking force of the spinning reel is linearized.
Of course, the spring is not limited to the spinning reel, and may be used in other fields requiring a compression spring.
In this embodiment, in addition to the improvement of the spring, the structure of the knob seat 84 of the adjustment knob assembly 8 is also improved, the middle of the knob seat 84 is provided with a first round hole 841 through which the threaded section 41 of the spindle 4 can pass, and the other end of the knob seat 84 is provided with two positioning posts 842 axially extending and circumferentially spaced apart from each other.
For the improvement of the matching button seat 84, the threaded section 41 of the spindle 4 is circular in cross section, and two sides of the spindle adjacent to the threaded section are respectively provided with a plane to form a non-circular section 42 (see fig. 8); in order to prevent the knob seat 84 from rotating relative to the main shaft 4, the front key washer 71 includes a main washer 711 having a second circular hole 711a in the middle and an auxiliary washer 712 seated in a limiting groove 711b on the end surface of the main washer 711, so that the auxiliary washer 712 can rotate together with the main washer 711, and a special-shaped hole is formed in the middle of the auxiliary washer 712, and the special-shaped hole is composed of a third circular hole 712a and a long hole 712b which are communicated with each other, the second and third circular holes can be penetrated by the threaded section 41 of the main shaft 4, the non-circular section 42 of the main shaft can slide into the long hole 712b from the third circular hole 712a, and a positioning groove 711c for inserting the positioning column 842 on the knob seat is formed on the end surface of the main washer 711. That is, the front key washer 71 is made into a split structure, the purpose of only moving along the axial direction of the main shaft is realized by utilizing the special-shaped hole on the auxiliary washer 712 to assemble with the main shaft 4, and the main washer 711 realizes the requirement of only moving along the axial direction of the main shaft through the auxiliary washer 712. The button seat 84 can move only axially relative to the spindle 4 by the engagement of the positioning post 842 with the positioning groove 711 c.
In order to ensure a quick positioning between the auxiliary washer 712 and the main washer 711, a magnet 713 is provided in the limit groove 711b, which attracts the auxiliary washer 712. The magnets 713 may be disposed to correspond to the end faces of the auxiliary washer 712, but in order to save costs, in this embodiment, two lugs 712c extend radially from the auxiliary washer 712, and the magnets are disposed to correspond to the two lugs.
During assembly, before the adjustment button assembly is assembled on the spindle 4, the magnet 713 is placed in the limiting groove 711b of the main washer 711, the magnet 713 is positioned by glue, the auxiliary washer 712 is sleeved on the spindle 4 by the third round hole of the auxiliary washer 712 and moves axially until the non-circular section 42 of the spindle 4 is reached, the auxiliary washer 712 is moved radially, the non-circular section 41 of the spindle slides into the long hole 712b from the third round hole 712a, and the auxiliary washer 712 is moved slightly axially, falls into the limiting groove 711b of the main washer and is adsorbed to the magnet 713. The spindle 4 is then inserted into the knob assembly 8 by the first circular hole 841 of the knob holder 84, and the positioning post 842 of the knob holder 84 is partially inserted into the positioning groove 711c of the main washer 711, which is shorter than the depth of the positioning groove 711c, with reference to fig. 2. The adjustment knob 82 is then rotated (three turns in the figure) to bring the knob seat 84 into abutment with the front key washer 71 by the action of the spring 83 (see figure 3). Thereafter, if the braking force needs to be adjusted, the adjusting button 82 is rotated again, so that the button seat 84 presses the front key washer 71 axially to press the brake washer 72 against the reel 5, and when the spring 83 is completely tightened, see fig. 3, the braking force is maximum. The force adjusting principle is disclosed in the application publication No. CN110384079A, and is not described in detail herein.
