[0002] The vertical intercalary bell piece device is an instrument for assisting body -building exercise and completing strength training action, aims at improving the convenience and safety of body -building demand.

[0003] The traditional adjustable bell piece device realizes weight adjustment mainly through threaded screwing or bolt fixing mode, and has the defects of low operation efficiency and poor stability. Although the intercalary bell piece device on the market improves the disassembly and assembly speed through the buckle structure, the following technical bottlenecks exist: most products rely on single intercalary buckle, and the lock buckle is easily separated due to vibration during violent movement, so there is the risk of instrument falling; the existing rotary locking mechanism, for example, US20230271050A1, adopts the rotary handle adjustment design, and the user may trigger unlocking when slightly rotating the handle at the non-locking angle, so there is the risk of bell piece falling caused by misoperation; in order to realize the anti -drop function, part of the scheme, for example, US20240042264A1, adds independent safety components, so that the number of components increases, the maintenance cost increases, and the multi -stage operation process reduces the user experience.

[0004] Therefore, it is necessary to propose a novel bell piece device, which can ensure the stability of connection and realize the optimization of quick disassembly and assembly and anti -misoperation function. SUMMARY

[0005] The utility model provides a vertical intercalary bell piece device to solve the problems in the above background art.

[0006] In order to realize the above invention purpose, the utility model adopts the following technical scheme:

[0007] The quick weight adjustment and stable locking are realized by optimizing the connecting structure of the handle and the bell piece. The fixed sheets are welded at both ends of the handle body, the fixed sheets and the bell piece are inserted and matched through the through hole and the mounting groove, the long groove and the short groove are extended from the center through hole of the bell piece, and the second connecting piece containing the limiting groove and the positioning groove is arranged in the short groove. The limiting rod of the knob is arranged in the through hole, the limiting surface of the limiting rod is matched with the groove width of the mounting groove of the bell piece, and the longitudinal displacement is limited. The elastic clamping structure is arranged in the knob body, the positioning protrusion is driven to be separated or embedded in the positioning hole of the bell piece through the button, and secondary mechanical locking is formed. The weight is adjusted by increasing or decreasing the number and the through hole of the bell piece, the limiting surface is parallel to the mounting groove by pressing the button and rotating the knob by 90 degrees during disassembly, and the bell piece can be taken out longitudinally. The structure eliminates the assembly gap and avoids micro-motion wear. The anti-skid lines or replaceable silica gel sleeve of the handle enhance the comfort of holding. The vertical insertion and double locking mechanism are used, the one-key operation is realized while the bearing strength is guaranteed, the training efficiency and safety are obviously improved, and the personalized fitness demand is met.

[0008] The utility model has the beneficial effects that relative to prior art:

[0009] The vertical insertion type bell piece device is used in the process, the connecting piece structure between the bell pieces limits that the bell pieces can only be assembled and disassembled along the vertical direction, accidental falling caused by horizontal displacement is effectively prevented, the double locking mechanism of the knob and the outermost bell piece connected through the locking assembly can ensure that the stable fastening state is maintained under long-term high-frequency use, and the core operation mechanism adopts integrated linkage design, so that a user only needs to rotate the center connecting rod, and the quick assembly or disassembly of all bell pieces can be completed synchronously, while the safety of the equipment is guaranteed, the device operation is simplified, and the training efficiency is improved.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. The description of the at least one exemplary embodiment is actually illustrative, rather than any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] The utility model discloses a vertical plug -in type bell piece device, which is convenient for weight adjustment and has high flexibility in use.

[0033] Referring to Figure 1 and Figure 2 , the vertical plug -in type bell piece device 10 of the embodiment comprises a handle 100, a bell piece 200 and a knob 300 with a limiting rod 320 (see Figure 11 ). The handle 100 has a hollow main body 101 with both ends open, and the main body 101 has a certain length, facilitating single -hand or double -hand holding of the user. The handle 100 has a cylindrical outer surface, and anti -skid lines 110 are arranged on the outer surface, and the anti -skid lines 110 are uniformly distributed on the surface of the handle 100, for increasing the friction force when holding, preventing the bell piece device from being dropped due to hand sweat or fatigue during high -intensity training.

[0034] In other embodiments (not shown in the drawings), the shape of the handle 100 can be replaced by a regular polygon, an ellipse or a bionic ergonomic curved surface according to the user's demand, so as to further improve the holding comfort and training effect. For example, a corresponding recessed area is designed for each finger, and the finger is placed in the corresponding recessed area when gripping, so as to facilitate the overall force of the palm. In addition, the handle 100 can also adopt a telescopic sleeve structure, and the length is segmented and locked (such as 5 gears) through the built -in ratchet mechanism, which is suitable for different training action requirements. In the anti -skid design aspect, the anti -skid lines 110 can also be replaced by a silica gel anti -skid sleeve, which is detachably mounted on the outer surface of the handle 100, which can increase the friction and provide soft hand feeling.

[0035] As shown in Figure 1 , a fixed sheet 120 is welded at each end of the handle 100, and a first through hole 102 (see Figure 2 ) is formed in the handle 100 along the length direction of the handle. The welded connection of the fixed sheet 120 and the handle 100 ensures the load bearing reliability of the overall structure, and is especially suitable for high -frequency, large -weight power training scenes. As an alternative (not shown in the drawings), the handle 100 and the fixed sheet 120 can also adopt other forms of fixed connection mode, for example, the handle 100 and the fixed sheet 120 are fixed by bolts, no matter what kind of connection mode, as long as the fixed sheet 120 and the handle 100 form fixed connection.

[0036] Referring to Figure 2 and Figure 3In the embodiment, the second through hole 121 is formed in the middle of the fixed sheet 120, and the diameter of the second through hole 121 is consistent with the diameter of the first through hole 102 of the handle 100. When the fixed sheet 120 is welded to the end of the handle 100, the first through hole 102 is coincided with the second through hole 121.

[0037] Referring to Figure 3 and Figure 4 , the mounting cavity 122 is formed in the inside of the fixed sheet 120, the first connecting piece 130 includes a common wall 131, a first plug plate 132 and a stop plate 133 extending from the common wall 131, wherein the first plug plate 132, the common wall 131 and the stop plate 133 form a “U”-shaped clamping groove 134, the first plug plate 132 is inserted into the mounting cavity 122 and fixed in the mounting cavity 122 by bolts, so that the first connecting piece 130 is fixedly installed on the fixed sheet 120.

[0038] In other embodiments (not shown in the drawings), the mounting cavity 122 and the first plug plate 132 can also be cancelled, and the first connecting piece 130 is integrally arranged on the fixed sheet 120, that is, the common wall 131 and the stop plate 133 are radially extended from the center of the fixed sheet 120, so that the fixed sheet 120, the common wall 131 and the stop plate 133 form a “U”-shaped clamping groove 134. This structure can effectively avoid the problem of micro-motion wear under high frequency use by eliminating the assembly gap of the traditional plug-in cooperation.

[0039] Referring to Figures 5-7 , in the embodiment, the outer contour of the bell sheet 200 is basically the same as that of the fixed sheet 120, so that a gapless fit is formed during assembly. The bell sheet 200 can also be provided with different numbers of through holes 201, and the mass gradient of the bell sheet body can be accurately adjusted by increasing or decreasing the number of the through holes 201, so as to provide more weight options for users. In some embodiments, the surface of the bell sheet 200 is provided with a laser-etched two-dimensional code mark, the etching depth is 0.05-0.1 mm, and the two-dimensional code mark contains information such as weight parameter, production batch and material composition. In addition, the two-dimensional code mark can also be replaced by a micro RFID chip embedded in the edge of the bell sheet to store weight, centroid coordinates and use history data.

[0040] In other embodiments (not shown in the drawings), the fixed sheet 120 can also be square, circular, diamond-shaped or any other desired shape.

[0041] As Figure 5 and Figure 6As shown, the third through hole 210 is provided in the center of the bell piece 200, and has substantially the same aperture as the first through hole 102 and the second through hole 121. The third through hole 210 extends towards the opposite ends of the bell piece 200, and forms a mounting groove 220 at one end of the third through hole 210. The mounting groove 220 penetrates the lower edge 202 of the bell piece 200, and forms a long groove 221. The long groove 221 forms an open guiding channel through the edge of the bell piece 200, and facilitates the radial insertion of the limiting rod 320 of the knob 300 (see Figure 11 ). The other end of the mounting groove 220 terminates on the bell piece 200, and forms a short groove 222. The long groove 221 and the short groove 222 each have a groove width W1 that is not greater than the aperture of the third through hole 210. Therefore, when the limiting rod 320 is inserted into the third through hole 210, the bell piece 200 can be prevented from moving away from the limiting rod 320 in a direction perpendicular to the length of the limiting rod 320, i.e., in a longitudinal direction.

[0042] As shown in Figure 8 and Figure 9 , the short groove 222 is provided with a second connecting member 230. In the present embodiment, the second connecting member 230 includes a second insertion plate 231 and a positioning block 232. The second insertion plate 231 is arranged in the short groove 222, and extends from the short groove 222 towards the long groove 221. The positioning block 232 includes a receiving groove 233 formed at the upper end of the second connecting member 230. The second insertion plate 231 is inserted into the receiving groove 233, and is fixedly connected to the positioning block 232 by a fixing member 240. In the present embodiment, the fixing member 240 is a bolt.

[0043] As shown in Figure 9 , the positioning block 232 further includes a common wall 2321, a limiting plate 2322 extending from the common wall 2321, and a positioning plate 2323. The positioning plate 2323 is further provided with a positioning hole 2324. The limiting plate 2322 and the common wall 2321 form a reverse “U”-shaped limiting groove 2325, and the positioning plate 2323 and the common wall 2321 form a “U”-shaped positioning groove 2326. The inner wall of the limiting groove 2325 is provided with an array of staggered protrusions, which are used to enhance the frictional locking with the clamping groove 134 or the positioning groove 220.

[0044] Referring to Figure 10The thickness D1 of the stop plate 133 is the same as the slot width D2 of the limiting slot 2325, and the stop plate 133 and the limiting slot 2325 form a transition fit when the first connecting piece 130 and the second connecting piece 230 form a transverse interlocking. The thickness D3 of the limiting plate 2322 and the slot width D4 of the positioning slot 2326 are the same, and the thickness D5 of the positioning plate 2323 and the slot width D2 of the limiting slot 2325 are the same. When the two bell plates 200 form a transverse interlocking through the second connecting piece 230, a transition fit is formed between the limiting plate 2322 and the positioning slot 2326, and between the positioning plate 2323 and the limiting slot 2325.

[0045] In other embodiments (not shown in the drawings), the fixing piece 240 is not limited to a bolt structure, but can also use a spring latch instead of a bolt, which can be quickly disassembled through pin self-locking. The built-in elastic element can automatically compensate for the assembly gap and eliminate axial movement during movement. A buckle structure can also be used, and an elastic buckle is arranged on the side wall of the positioning block 232 to realize instantaneous locking of the bell plate 200 and the second connecting piece 230 by using the material deformation characteristics. Alternatively, the bell plate 200 and the second connecting piece 230 can be integrally arranged, and the common wall 2321, the limiting plate 2322 and the positioning plate 2323 are directly cast on the bell plate 200 body, that is, the common wall 2321, the limiting plate 2322 and the positioning plate 2323 are directly extended downward from the short slot 222 to form the limiting slot 2325 and the positioning slot 2326.

[0046] As shown in Figure 1 and 12 , the width W2 of the clamping slot 134 on the first connecting piece 130 is configured to be not greater than the width W1 of the short slot 222 in the bell plate 200, so that the bell plate 200 can be embedded in the clamping slot 134 through the limiting plate 2322, and at the same time, the stop plate 133 of the clamping slot 134 is also embedded in the limiting slot 2325 (see Figure 10 ), so that the bell plate 200 and the fixing plate 120 form a fixed connection, and the movement of the bell plate 200 and the fixing plate 120 in the axial direction of the handle 100 is limited. At this time, the bell plate 200 is only allowed to move upward in the radial direction perpendicular to the axial direction of the handle 100 to separate from the fixing plate 120. Similarly, other bell plates 200 can also limit the movement between the two bell plates 200 in the axial direction of the handle 100 by embedding the limiting plate 2322 in the positioning slot 2326 of another bell plate and embedding the positioning plate 2323 in the limiting slot 2325.

[0047] As shown in Figure 6, when multiple bell blades 200 and fixing plates 120 are installed together, the first through hole 102, the second through hole 121, and the third through hole 210 overlap and form a channel 1021. The limiting rod 320 of the knob 300 can pass through the channel 1021, and the end of the limiting rod 320 passes through the first through hole 102 of the handle 100, thereby limiting the movement of the bell blades 200 in the radial direction of the handle 100 (see Figure 6). Figure 13 ).

[0048] like Figure 11 As shown, the knob 300 includes a main body 310 and a limiting rod 320 extending outward from the main body 310. The limiting rod 320 has a certain length and can accommodate a large number of bell blades 200 along its length. The limiting rod 320 has two opposing limiting surfaces and two opposing arc surfaces along its length, including a first limiting surface 321 and a second limiting surface 322, as well as a first arc surface 323 and a second arc surface 324 (see...). Figure 14 ).

[0049] In some embodiments, the limiting rod adopts a telescopic sleeve structure with multi-stage length adjustment function to accommodate more bells.

[0050] like Figure 12 As shown, there is a distance W3 between the first limiting surface 321 and the second limiting surface 322. This distance W3 is approximately the same as the width W1 of the long slot 221 and the short slot 222 of the bell 200, ensuring that the mounting slot 220 can smoothly pass through the limiting rod 320 in the vertical direction when the user inserts the bell 200. The first arc surface 323 and the second arc surface 324 have a first through hole 102 and a second through hole 121 (see...). Figure 14 With the same radius of curvature, when the limiting rod 320 passes through the channel 1021 and is rotated so that the first arc surface 323 and the second arc surface 324 come into contact with the arc surface of the inner wall of the second through hole 121, the limiting rod 320 can restrict the movement of the bell 200 in the radial direction of the handle 100.

[0051] like Figure 15 As shown, the main body 310 is also provided with a snap-fit ​​structure 340, which includes a third insert plate 341 and a positioning protrusion 342. The third insert plate 341 can be embedded in the positioning groove 2326 of the bell slat 200 (see...). Figure 9 The limiting rod 320 is prevented from moving axially along the handle, thereby locking the entire bell mechanism, and the positioning protrusion 342 can be fitted into the positioning hole 2324 (see...). Figure 9 The inner part of the knob 300 forms a secondary lock with the positioning hole 2324, which can strengthen the fixed connection between the knob 300 and the bell 200, prevent the third insert plate 341 from falling out of the positioning groove 2326 during the user's exercise, and prevent the knob 300 from accidentally coming loose.

[0052] Specifically, referring to Figures 15-17 In the embodiment, a sliding cavity 311 is formed on the main body 310, the positioning protrusion 342 is arranged in the sliding cavity 311, a button 350 is arranged on the upper portion of the sliding cavity 311, at least a portion of the button 350 is exposed outside the main body 310, the rear wall surface 3421 of the positioning protrusion 342 and the bottom surface 3111 of the sliding cavity 311 are abutted by the elastic member 360, so that the positioning protrusion 342 can automatically rebound along the length direction of the limiting rod 320, i.e., the horizontal direction, to ensure that the positioning protrusion 342 is timely clamped and fixed with the positioning hole 2324 (see Figure 9 ).

[0053] In other embodiments (not shown in the figure), the reset structure formed by the elastic member 360 can be replaced by a gear structure, the horizontal expansion and contraction of the clamping structure 340 is controlled by the rotation of the gear, the structure can provide more accurate positioning control and enhance the locking effect of the knob 300 and the bell piece 200, or the elastic member 360 is not arranged, the magnetic attraction part can be arranged on the positioning protrusion 342 and the positioning groove 2326, or the magnetic attraction part is arranged on the positioning protrusion 342 and the metal material is used to manufacture the positioning groove 2326, so that the structure can be simplified and the automatic rebound of the positioning protrusion 342 along the horizontal direction can be effectively ensured.

[0054] As shown in Figure 15 and Figure 16 , in the embodiment, the positioning protrusion 342 is further provided with an inclined surface 3422, the button 350 is provided with an inverse inclined surface 351, the inverse inclined surface 351 of the button 350 is in contact with the inclined surface 3422 of the positioning protrusion 342, when the button 350 is driven to move towards the sliding cavity 311, the inverse inclined surface 351 of the button 350 will press the inclined surface 3422 of the positioning protrusion 342, so that the positioning protrusion 342 moves in the axial direction of the handle 100 in the sliding cavity 311, at this time, the movement direction of the positioning protrusion 342 is perpendicular to the driving direction of the button 350. When the button 350 is reset, the positioning protrusion 342 will be driven to the initial position by the elastic force of the elastic member 360, i.e., embedded in the positioning hole 2324 (see Figure 9 ).

[0055] In other embodiments (not shown in the figure), a push-type telescopic locking structure can also be used, the button 350 is arranged on the side surface 301 of the knob 300, and the transverse displacement of the clamping structure 340 is controlled by a spring structure. When the user needs to replace the bell piece, press the button 350 to move the clamping structure 340 away from the positioning plate 2323, so that the positioning protrusion 342 is disengaged from the positioning hole 2324; after the replacement is completed, press the button 350 again, and the clamping structure 340 moves towards the positioning plate 2323, and the locking of the knob 300 on the bell piece 200 is recompleted. In other embodiments, the movement conversion mechanism between the button 350 and the positioning protrusion 342 can also be one of a gear transmission or a connecting rod mechanism, so as to convert the longitudinal pressing action of the button 350 into the movement action of the positioning protrusion 342 in the axial direction of the handle 100.

[0056] The preferred embodiment provided by the utility model can be operated by the following method:

[0057] When the user needs to replace the bell piece, first press the button 350 downward, at this time the mechanical transmission of the button will drive the positioning protrusion 342 to slide along its length direction and away from the positioning hole 2324, so as to completely release the positioning hole 2324. After completing the unlocking action, the user can rotate the knob 300 clockwise or counterclockwise by 90°, and the rotation action drives the limiting rod 320 to change the key position, that is, the first limiting surface 321 and the second limiting surface 322 change from the locking state perpendicular to the groove wall of the long groove 221 to the release state parallel to the groove wall. At this time, the transverse constraint of the limiting rod on the bell piece 200 is completely released, and the user can pull out the limiting rod 320 by a distance, so as to easily take out the bell piece to be adjusted in the vertical direction. After completing the weight replacement, the limiting rod 320 needs to be pushed towards the handle 100, and then the button 350 is pressed again and the knob 300 is rotated in the reverse direction to the initial position. When the knob is reset, the double limiting surfaces of the limiting rod will be locked again perpendicular to the groove wall of the long groove 221, at this time the button 350 is released, and the internal elastic member 360 will automatically push the positioning protrusion 342 to be accurately inserted into the positioning hole 2324, so as to realize the locking protection of the remaining bell piece 200, and ensure the stability and safety of the instrument during use.

[0058] In summary, the utility model realizes the following technical effect: the bell piece 200 realizes quick dismounting without tools through the design of the longitudinal plug-in cooperation through hole 210 and the mounting groove 220, significantly improves the weight adjustment efficiency; the relative limiting surface of the limiting rod 320 and the through hole 210 and the mounting groove 220 of the bell piece 200 are accurately matched, ensuring the longitudinal accurate positioning of the bell piece, avoiding the installation difficulty caused by misplacement; meanwhile, the clamping structure 340 of the rear elastic member 360 is matched with the positioning hole 2324 through the positioning protrusion 342, forming secondary locking, effectively resisting accidental unlocking caused by vibration or accidental touch; in addition, the transmission design of the button 350 and the clamping structure 340 enables the bell piece device to realize one-key unlocking, convenient operation.

[0059] The application of the utility model not only meets the demand of the user for the weight individualization adjustment of the bell piece device, but also greatly simplifies the assembly and disassembly process of the bell piece device, improves the market competitiveness and user satisfaction of the bell piece device.

[0060] The technical scheme described in the utility model is not limited to the dumbbell field, and the unique design concept and structural principle are also applicable to barbells and kettlebells. In the barbell application scene, the core connection and adjustment structure in the technical scheme is adapted to the barbell, the quick mounting and dismounting of the barbell piece are realized, thereby effectively meeting the diversified demand for the weight of the barbell under different training intensities, and the flexibility and efficiency of training are greatly improved.
