Description

Technical Field

[0001] The utility model relates to the field of massage stick equipment, in particular to an assembleable massage stick. Background Art

[0002] As a tool for soothing nerves, relieving fatigue and soreness, and promoting blood circulation, the massage stick is easy to use in daily life due to its compact structure.

[0003] The most common massage stick on the market includes a main shaft, a massage roller and a handle bar. The massage roller is rotatably sleeved on the main shaft, and the handle bars arranged in pairs are directly fixed to the two ends of the main shaft. All massage rollers are limited to the two handle bars. However, the overall length of this massage stick is too long, and the space volume occupied during the product transportation process is large, and the transportation cost increases accordingly; if the various parts on the massage stick are disassembled for transportation, the overall space volume and transportation cost of the product can be greatly reduced; therefore, how to disassemble the massage stick to save volume and transportation costs while designing a massage stick that is easy to assemble is a problem that is currently difficult to solve in the industry. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes an assemblable massage stick, which solves the problem that the traditional massage stick cannot be assembled, resulting in a large space volume and high transportation cost.

[0005] The technical solution adopted by the utility model is: an assembleable massage stick, including an intermediate tube and a handle rod, the intermediate tube is sleeved with a massage roller; it also includes a connecting tube and a locking tube, the connecting tube includes a connecting part and a locking part, the connecting part and the end of the intermediate tube are fixedly connected, a deformation gap is provided on the locking part, an external thread is provided on the locking part, and an internal thread is provided on the locking tube; when the external thread and the internal thread are screwed together, the locking tube presses against and locks the handle rod.

[0006] Through the above technical solution, when assembling the massage stick of the utility model, after each massage roller is sleeved on the middle tube, the connecting part of the connecting tube is fixedly connected to the middle tube and the locking part is sleeved on the handle rod, and then the locking tube and the locking part are tightened by the external thread and the internal thread to complete the assembly. The structure is simple and the assembly is very convenient. The setting of the deformation gap makes the locking part deform more when the external thread and the internal thread are tightened, so that the locking part and the handle rod are more stably locked.

[0007] Furthermore, the inner diameter of the intermediate tube is greater than or equal to the outer diameter of each location on the handlebar.

[0008] Through the above technical solution, each part of the handle rod can be inserted into the middle tube. When the massage stick is in a disassembled state, the handle rod can be inserted into the middle tube to further save space and volume, thereby reducing transportation costs.

[0009] Furthermore, a positioning protrusion is provided inside the connecting part, and a positioning hole is provided on the intermediate tube; or, a positioning hole is provided on the connecting part, and a positioning protrusion is provided on the intermediate tube; when the positioning protrusion and the positioning hole are engaged, the connecting part and the end of the intermediate tube are fixedly connected.

[0010] Through the above technical solution, the structures of the positioning protrusion and the positioning hole are simple, making the production and manufacturing very simple; the user can connect the connecting tube and the intermediate tube by inserting the positioning protrusion into the positioning hole, making the assembly process more convenient.

[0011] Furthermore, the positioning protrusion is provided with an inclined surface; the positioning protrusion is provided inside the connecting portion, and the inclined surface is inclined toward a side of the connecting portion opening; or, the positioning protrusion is provided on the intermediate tube, and the inclined surface is directed toward the end of the intermediate tube to which the positioning protrusion is closest.

[0012] Through the above technical solution, the setting of the inclined surface makes it possible to reduce the resistance generated by the positioning protrusion when the connecting tube and the intermediate tube are close to each other and sleeved together, thereby further facilitating the assembly of the massage stick.

[0013] Furthermore, a limiting protrusion is provided inside the connecting portion, and a limiting notch is provided on the end of the intermediate tube, and the limiting protrusion and the limiting notch are embedded.

[0014] Through the above technical solution, the cooperation between the limiting protrusion and the limiting notch can share the torque generated between the intermediate tube and the connecting tube, so that the force between the positioning protrusion and the positioning hole is smaller, reducing the wear of the positioning protrusion and extending its service life.

[0015] Furthermore, the handle rod includes a first section and a second section, the outer diameter of the first section is larger than the outer diameter of the second section, and the first section extends into the intermediate tube; an annular section is formed between the first section and the second section, an annular portion is provided between the connecting portion and the locking portion, and the annular portion abuts against the annular section.

[0016] Through the above technical solution, after the massage stick is assembled, the annular part forms an abutment and limiting effect on the annular section, which prevents the handle rod from detaching from the middle tube during use, making the use state more stable; after the first section is extended into the middle tube, the handle rod together with the middle tube can withstand more bending force, making the overall structure stronger and longer in service life.

[0017] Furthermore, the annular portion abuts against the end portion of the intermediate tube.

[0018] Through the above technical solution, the abutting action between the annular portion and the end of the intermediate tube can share the axial pressure generated by the connecting tube and the intermediate tube, thereby preventing the axial force from destroying the fixed connection between the connecting portion and the intermediate tube.

[0019] Furthermore, the number of the deformation gaps arranged on the locking portion is at least two, and the deformation gaps are evenly distributed in the circumferential direction.

[0020] Through the above technical solution, the number of deformation gaps is appropriate, so that when the external thread and the internal thread are tightened, the locking part undergoes more deformation, further improving the structural stability of the locking part and the handle rod; when the external thread and the internal thread are tightened, the force on the locking part is more uniform, avoiding the situation where the structure on the locking part undergoes plastic deformation or even fracture due to uneven force.

[0021] Furthermore, an anti-slip convex strip is arranged on the outer surface of the second section, and the anti-slip convex strip extends along the length direction of the handle rod, and the anti-slip convex strip is tightly pressed against the inside of the locking portion.

[0022] Through the above technical solution, the static friction between the handle bar and the locking part in the circumferential direction is made greater, thereby preventing the handle bar from rotating relative to the locking part during use, making the use state more stable; in addition, more friction is generated when a person grasps the handle bar to prevent slipping.

[0039] refer to Figure 1-Figure 5, an assembled massage stick, including an intermediate tube 1 and a handle rod 2, the intermediate tube 1 is sleeved with a massage roller 3; it also includes a connecting tube 4 and a locking tube 5, the connecting tube 4 includes a connecting portion 401 and a locking portion 402, the connecting portion 401 is fixedly connected to the end of the intermediate tube 1, a deformation gap 403 is provided on the locking portion 402, an external thread 404 is provided on the locking portion 402, and an internal thread 501 is provided on the locking tube 5; when the external thread 404 and the internal thread 501 are screwed together, the locking tube 5 is pressed against and locked to the handle rod 2.

[0040] When assembling the massage stick of the utility model, after each massage roller 3 is sleeved on the middle tube 1, the connecting portion 401 of the connecting tube 4 is fixedly connected to the middle tube 1 and the locking portion 402 is sleeved on the handle rod 2, and then the locking tube 5 and the locking portion 402 are tightened together through the external thread 404 and the internal thread 501 to complete the assembly. The structure is simple and the assembly is very convenient; the setting of the deformation gap 403 makes the locking portion 402 deform more when the external thread 404 and the internal thread 501 are tightened together, so that the locking portion 402 and the handle rod 2 are more stably locked.

[0041] The number of the connecting tube 4 , the locking tube 5 and the handle rod 2 are all two, and the three are symmetrically arranged on both sides of the middle tube 1 .

[0042] The handle bar 2 and the middle tube 1 are both made of hard material, and preferably the middle tube 1 and the handle bar 2 are both made of alloy steel.

[0043] Preferably, the extension direction of the deformation gap 403 is consistent with the length direction of the handle bar 2 , and one end of the deformation gap 403 is connected to the opening of the locking portion 402 .

[0044] The inner diameter of the intermediate tube 1 is greater than or equal to the outer diameter of each location on the handlebar 2 .

[0045] All parts of the handle bar 2 can be inserted into the middle tube 1. When the massage stick is in a disassembled state, the handle bar 2 can be inserted into the middle tube 1 to further save space and volume, thereby reducing the transportation cost.

[0046] refer to Figure 3-Figure 5 , a positioning protrusion 405 is provided inside the connection part 401, and a positioning hole 101 is provided on the intermediate tube 1; or, a positioning hole 101 is provided on the connection part 401, and a positioning protrusion 405 is provided on the intermediate tube 1; when the positioning protrusion 405 and the positioning hole 101 are engaged, the connection part 401 and the end of the intermediate tube 1 are fixedly connected. The positioning protrusion 405 and the positioning hole 101 have a simple structure, which makes the production and manufacturing very simple; the user can realize the connection between the connection tube 4 and the intermediate tube 1 by inserting the positioning protrusion 405 into the positioning hole 101, making the assembly process more convenient.

[0047] The positioning protrusion 405 is provided with an inclined surface 406; the positioning protrusion 405 is provided inside the connecting portion 401, and the inclined surface 406 is inclined toward the opening side of the connecting portion 401; or, the positioning protrusion 405 is provided on the intermediate tube 1, and the inclined surface 406 is directed toward the end of the intermediate tube 1 to which the positioning protrusion 405 is closest. The provision of the inclined surface 406 makes the resistance generated by the positioning protrusion 405 smaller during the process of the connecting tube 4 and the intermediate tube 1 being close to each other, further facilitating the assembly action of the massage stick.

[0048] A limiting protrusion 408 is disposed inside the connecting portion 401 , and a limiting notch 102 is disposed on the end of the intermediate tube 1 , and the limiting protrusion 408 and the limiting notch 102 are engaged with each other.

[0049] The cooperation between the limiting protrusion 408 and the limiting notch 102 can share the torque generated between the intermediate tube 1 and the connecting tube 4, so that the force between the positioning protrusion 405 and the positioning hole 101 is smaller, reducing the wear of the positioning protrusion 405 and extending its service life.

[0050] In the present invention, the positioning protrusion 405 is preferably disposed inside the connecting portion 401 , and the positioning hole 101 is opened on the middle tube 1 .

[0051] refer to Figure 3-Figure 5 The handle bar 2 includes a first section 201 and a second section 202. The outer diameter of the first section 201 is greater than the outer diameter of the second section 202. The first section 201 extends into the middle tube 1. An annular section 203 is formed between the first section 201 and the second section 202. An annular portion 407 is provided between the connecting portion 401 and the locking portion 402. The annular portion 407 abuts against the annular section 203.

[0052] After the massage stick is assembled, the annular portion 407 forms an abutment and limiting effect on the annular section 203, preventing the handle rod 2 from being separated from the middle tube 1 during use of the massage stick, making the use state more stable; after the first section 201 is extended into the middle tube 1, the handle rod 2 together with the middle tube 1 can withstand more bending force, making the overall structure stronger and having a longer service life.

[0053] refer to Figure 3 The annular portion 407 abuts against the end of the intermediate pipe 1.

[0054] The abutting action between the annular portion 407 and the end of the intermediate tube 1 can share the axial pressure generated between the connecting tube 4 and the intermediate tube 1, thereby preventing the axial force from destroying the fixed connection state between the connecting portion 401 and the intermediate tube 1.

[0055] There are at least two deformation gaps 403 disposed on the locking portion 402 , and the deformation gaps 403 are evenly distributed in the circumferential direction.

[0056] The number of deformation gaps 403 is appropriate, so that when the external thread 404 and the internal thread 501 are tightened, the locking part 402 undergoes more deformation, further improving the structural stability of the locking part 402 and the handle rod 2; when the external thread 404 and the internal thread 501 are tightened, the force on the locking part 402 is more uniform, avoiding the situation where the structure on the locking part 402 undergoes plastic deformation or even fracture due to uneven force.

[0057] Preferably, the number of deformation gaps 403 on a single locking portion 402 is four.

[0058] An anti-skid convex strip 204 is provided on the outer surface of the second section 202 . The anti-skid convex strip 204 extends along the length direction of the handle bar 2 . The anti-skid convex strip 204 is pressed tightly against the inside of the locking portion 402 .

[0059] This makes the static friction between the handle bar 2 and the locking portion 402 in the circumferential direction greater, thereby preventing the handle bar 2 from rotating relative to the locking portion 402 during use, making the use state more stable; in addition, it also generates more friction when a person grasps the handle bar 2 to prevent slipping.

[0060] When assembling the massage stick of the utility model, firstly sleeve each massage roller 3 onto the middle tube 1, then sleeve the locking portion 402 onto the handle rod 2, and then, when the connecting portion 401 of the connecting tube 4 is close to and sleeved onto the middle tube 1, align the connecting limit protrusion 408 and the limit notch 102, and align the snap-fit ​​positioning protrusion 405 and the positioning hole 101, and finally, tighten the locking tube 5 and the locking portion 402 through the external thread 404 and the internal thread 501 to complete the assembly.
