Its working principle is to transmit vibration energy to concrete through the high-frequency vibration generated by the internal motor, expel bubbles, and improve the compressive strength and durability of concrete.

[0003] In the prior art, the vibrating rod used for cement usually has a rubber tube sheathed on the cable line to isolate it from the outside world and protect the cable line. During use, the rubber tube and the cable line will inevitably bend, and there is no deformation redundancy design between the two. When bending, relative displacement will occur between the rubber tube and the cable line, and the electrical connection part between the cable line and the vibrating rod body will be squeezed or pulled by force, resulting in poor contact and a high failure rate. At the same time, the existing vibrating rod needs to be connected to a specific high-voltage power supply to work, and has poor adaptability and practicality. Summary of the invention

[0022] Embodiment 1

[0023] like Figure 12-13 As shown, an ultra-low voltage vibrator powered by a portable mobile power source comprises a vibrator body 1 and a switch box 2, and a low-voltage power plug 4 connected to a low-voltage power source, wherein one end of the vibrator body 1 is electrically connected to the switch box via a first cable output line S, and the switch box 2 is electrically connected to the low-voltage power plug 4 via a first cable input line S2, and the first cable output line S is provided with a rubber tube R respectively connected to the switch box 2 and the vibrator body 1, and a gap P is left between the inner wall of the rubber tube R and the outer peripheral surface of the first cable output line S. In this embodiment, the rubber tube R can provide good bending performance, ensuring that during use, the first cable output line S will not be damaged due to excessive bending, and will not affect the electrical connection part between the first cable output line S and the vibration rod body 1; secondly, the outer wall surface of the rubber tube R has been specially treated and has anti-slip and anti-wear properties, which can reduce the wear caused by external environmental factors during use and extend the service life of the product; at the same time, since the first cable output line S needs to extend into the vibration rod body 1 and connect with the driving part, the length of the rubber tube R is designed to be shorter than the length of the first cable output line S.

[0024] Specifically, Figure 1The vibrating rod body 1 is shown, and its front and rear ends both have a sealing structure. The vibrating rod body 1 includes a hollow metal cylinder 12, and a rear end cap 10 is provided at the rear end of the vibrating rod body 1. The rear end of the metal cylinder 12 is connected to the rear end cap 10 by a thread, and a first cable output line S that passes through the rear end cap 10 and is electrically connected to the vibrating rod body 1. The first cable output line S is used to drive the motor 13. The first cable output line S is introduced into the interior of the vibrating rod body 1 through the rear end cap 10 and is connected to the terminal of the motor 13. The motor 13 is installed in the metal cylinder 12 and is relatively fixed to the inner wall of the metal cylinder 12 to ensure that the motor 13 remains stable during the vibration process. Furthermore, an eccentric block 14 for generating vibration is also provided at the output end of the motor 13.

[0025] Regarding the details of the connection part between the first cable output line S and the vibrator body 1, in order to maintain the safety and service life of the first cable output line S, the present embodiment inserts the above-mentioned first cable output line S into a rubber tube R specially used for cement vibrators, and at least a portion of the rubber tube R is sleeved on the above-mentioned rear head 10, and a sealing structure is provided with the rear head 10, specifically, one end of the rubber tube R abuts against the shoulder 100 of the rear head 10, and a tube fastener 11 is sleeved on one end of the rubber tube R, which causes the rubber tube R to radially deform and shrink, thereby forcing the rubber tube R and the rear head 10 to form a concave-convex bite structure 101. Specifically, the above-mentioned concave-convex bite structure 101 includes a plurality of convex teeth 101-1 provided on the rear head 10, and the rubber tube R is radially deformed and contracted, so that a concave tooth groove 101-2 matching the convex tooth portion 101-1 is formed on the inner wall of one end of the rubber tube R, and the convex tooth portion 101-1 and the concave tooth groove 101-2 are mutually engaged, thereby enhancing the connection strength and sealing performance between the rubber tube R and the rear head 10, wherein these convex teeth 101-1 are evenly distributed axially along the outer wall of the rear head 10, forming one or more circles of convex structures. And as a variety of solutions, the above-mentioned concave tooth groove 101-2 can be directly formed when the rubber tube R is manufactured, or can be passively formed by extrusion of the tube fastener 11 during the later installation process (because the rubber part has elasticity and plasticity).

[0026] In this embodiment, the outer diameter of the shoulder 100 is greater than the outer diameter of the convex tooth portion 101-1. The rubber tube R is squeezed by the tube fastener 11, so that the rubber tube R and the rear head 10 are fixedly connected. In order to further improve the connection strength and stability, an axial anti-detachment structure 110 for preventing the rubber tube R from detaching from the rear head 10 is provided between the tube fastener 11 and the shoulder 100. The structure prevents the rubber tube R from detaching from the rear head 10 axially during vibration by mechanical locking.

[0027] Specifically, if Figure 1-Figure 2As shown, the above-mentioned axial anti-detachment structure 110 includes an axial extension part 110-1 connected to the tube fastener 11 and sleeved on the shoulder 100. An inner convex blocking part 110-2 vertically connected to the axial extension part 110-1 is provided at the end of the axial extension part 110-1 away from the tube fastener 11. The inner convex blocking part 110-2 contacts the end face of the shoulder 100 away from the rubber tube R. The close fit between the axial extension part 110-1 and the shoulder 100 not only provides axial fixation, but also enhances the sealing of this part. This sealing design can effectively prevent liquid, dust or other impurities from penetrating from the connection between the rubber tube R and the rear head 10, further improving the protection level of the vibrating rod body 1. The inner convex blocking part 110-2 is in close contact with the end face of the shoulder 100 to form a physical barrier, effectively preventing the rubber tube R from detaching from the rear head 10 in the axial direction due to vibration or external force. This structure is similar to a mechanical clamp or retaining ring, and ensures the stable fixation of the rubber tube R through physical limitation.

[0028] In addition, a front head 16 is also threadedly connected to the front end of the above-mentioned metal cylinder 12, and in order to further maintain the sealing of the connection between the front head 16, the rear head 10 and the metal cylinder 12, a sealing ring 17 is provided at the root of the thread where the front head 16, the rear head 10 and the metal cylinder 12 are threadedly connected, and an accommodating groove 170 for accommodating the sealing ring 17 is provided on the outer side wall of the front head 16 and the rear head 10. The sealing ring 17 can fit tightly on the inner wall of the metal cylinder 12 to form a double seal. At the same time, the elastic characteristics of the sealing ring 17 buffer the stress at the threaded connection, thereby reducing the risk of thread loosening due to vibration or mechanical shock.

[0029] Embodiment 2

[0030] The structure and principle of this embodiment are basically the same as those of the first embodiment. The difference lies in that, with respect to the vibration rod body of the first embodiment, this embodiment specifically describes a specific fixing method for the eccentric block.

[0031] The eccentric block 14 in the first embodiment is fixed in the metal cylinder 12 through two sets of double-row bearings 15. Figure 3-Figure 5 The figure shows the specific assembly state of the double-row bearing 15.

[0032] Specifically, the double-row bearing includes: an outer ring 150 and an inner ring 151 arranged coaxially, and spherical rollers 1520-1, spherical roller cages 1520-2, cylindrical rollers 1521-1, cylindrical roller cages 1521-2, etc. are arranged between the outer ring 150 and the inner ring 151. It can be imagined that the double-row bearing also includes other structures, such as lubricating oil, sealing structures, etc., which are all technologies well known to technical personnel in this field, so they will not be described in detail one by one here.

[0033] The outer ring 150 and the inner ring 151 are both cylindrical parts and are coaxially arranged. The outer ring 150 and the inner ring 151 are spaced apart and a mounting cavity 152 is provided therebetween. The annular space of the mounting cavity 152 facilitates component installation and oil lubrication.

[0034] Specifically, a spherical roller annular groove 1520 is annularly arranged in the mounting cavity 152. Specifically, arc-shaped notches 153 that are recessed inward and correspond to each other are provided on the inner wall of the outer ring 150 and the outer wall of the inner ring 151, and the arc-shaped notches 153 are communicated with the mounting cavity 152 to form the spherical roller annular groove 1520. A plurality of spherical rollers 1520-1 are provided in the spherical roller annular groove 1520, and the number of spherical rollers 1520-1 is determined according to the actual size. It can be imagined that the recessed depth of the arc-shaped notch 153 is smaller than the radius of the spherical roller 1520-1, and the spherical roller 1520-1 is partially located in the space of the mounting cavity 152, and the outer walls on both sides of the spherical roller 1520-1 are fitted and embedded in the arc-shaped notch 153. A spherical roller retainer 1520-2 is also provided in the spherical roller annular groove 1520. The spherical roller retainer 1520-2 is provided with space for the spherical rollers 1520-1 to be embedded one by one, so that the overall spherical rollers 1520-1 are kept in a circumferential distribution in the spherical roller annular groove 1520. The spherical rollers 1520-1 are used to achieve axial limitation of the entire bearing to prevent relative displacement between the inner ring 151 and the outer ring 150, while having corresponding pressure-bearing performance in the axial and radial directions.

[0035] A cylindrical roller annular groove 1521 is also circumferentially arranged in the installation cavity 152, and the cylindrical roller annular groove 1521 is spaced apart from the spherical roller annular groove 1520. Specifically, the inner wall of the end of the outer ring 150 away from the arc-shaped notch 153 and the outer wall of the inner ring 151 are provided with corresponding reaming notches 1500, and the reaming notch 1500 is communicated with the installation cavity 152 to form a cylindrical roller annular groove 1521, and a plurality of cylindrical rollers 1521-1 are arranged in the cylindrical roller annular groove 1521, and the number of cylindrical rollers 1521-1 is determined according to the actual size, and the recessed depth of the reaming notch 1500 is smaller than the radius of the cylindrical roller 1521-1, and the cylindrical roller 1521-1 is partially located in the space of the installation cavity 152, and the outer walls on both sides of the cylindrical roller 1521-1 fit in the inner wall of the reaming notch 1500. A cylindrical roller retainer 1521-2 is provided in the cylindrical roller annular groove 1521, and the cylindrical roller retainer 1521-2 keeps the cylindrical roller 1521-1 in a circumferential distribution in the cylindrical roller annular groove 1521. The cylindrical roller 1521-1 can make the double-row bearing bear a greater radial force. In this embodiment, the expansion notch 1500 is opened axially inward from the end of the installation cavity 152, which is convenient for machining the cylindrical roller annular groove 1521 and installing the cylindrical roller 1521-1.

[0036] Optimally, a step 1500-1 is provided at one end of the expansion notch 1500 close to the arc notch 153, and the cylindrical roller 1521-1 is axially abutted against the step 1500-1, and the structure of the outer ring 150 and the inner ring 151 is used as the axial limit of the single end of the cylindrical roller 1521-1, which facilitates the installation stability of the cylindrical roller 1521-1 in the cylindrical roller annular groove 1521. A clearance groove 1500-2 is provided at one end of the expansion notch 1500 close to the step 1500-1, and the clearance groove 1500-2 is conducive to the inflow of lubricating oil, and provides a sufficient lubrication surface on the side of the cylindrical roller 1521-1 close to the step 1500-1, thereby avoiding wear on the corner end of the step 1500-1.

[0037] In this embodiment, a clamping groove 1500-3 is provided at one end of the expansion notch 1500 away from the step 1500-1, and a clamping spring 154 is provided in the clamping groove 1500-3 to prevent the cylindrical roller 1521-1 from being separated from the cylindrical roller annular groove 1521. The clamping spring 154 is a C-shaped spring leaf, which is elastically embedded in the clamping groove 1500-3 to provide axial restriction on the other end of the cylindrical roller 1521-1. Optimally, a retaining ring 155 is provided between the retaining ring 154 and the end of the cylindrical roller 1521-1, and the retaining ring 155 increases the contact surface with the cylindrical roller 1521-1, and the retaining ring 155 increases the rotation performance of the end of the cylindrical roller 1521-1, thereby improving the rotation performance of the bearing.

[0038] In other embodiments, the expansion notch 1500 may also be disposed in the middle portion of the mounting cavity 152 .

[0039] The inner diameter of the spherical roller annular groove 1520 and the inner diameter of the cylindrical roller annular groove 1521 are both larger than the inner diameter of the mounting cavity 152. This structure prevents the spherical roller 1520-1 and the cylindrical roller 1521-1 from interfering with each other in their respective spherical roller annular grooves 1520 and cylindrical roller annular grooves 1521. More optimally, the inner diameter of the cylindrical roller annular groove 1521 is larger than the inner diameter of the spherical roller annular groove 1520, and the radial pressure-bearing performance of the bearing is improved by the cylindrical roller 1521-1. At the same time, the cylindrical roller 1521-1 preferentially bears the radial force of the bearing, which plays a role in protecting the bearing. In addition, the double-row bearing formed with the spherical roller 1520-1 supplements the axial positioning capability, and avoids the problem of misalignment between the outer ring 150 and the inner ring 151.

[0040] In this embodiment, mounting grooves 156 are provided at both ends of the mounting cavity 152. Dust covers 157 are provided in the mounting grooves 156 to seal both ends of the mounting cavity 152. The dust covers 157 prevent dust and impurities from entering the bearing and affecting the performance of the bearing.

[0041] Embodiment 3

[0042] This embodiment specifically describes the specific composition structure and advantages of the switch box 2; like Figure 6 As shown, the switch box of the extra-low voltage vibrator is arranged at the extra-low voltage vibrator conductor for switching on and off power, and specifically includes a low-voltage switch A2 electrically connected to the first cable input line S2 and the first cable output line S, wherein the switch box structure of the above-mentioned vibrator also includes a switch housing 20 with a switch accommodating through hole 200, which provides a solid housing for the switch box of the entire vibrator to protect the internal components from mechanical damage. Specifically, at least a portion of the first cable input line S2 and at least a portion of the first cable output line S extend into the switch housing 20, the purpose of which is to protect the connection ends of the above-mentioned first cable input line S2 and the first cable output line S, and at the same time isolate the connection ends from the outside to further improve the safety of the entire device, and the low-voltage switch A2 is in the switch accommodating through hole 200, and a switch waterproof pad 2 is provided in the switch housing 20. The switch waterproof pad 21 has a switch accommodating deformable portion 210 extending into the switch accommodating through hole 200, at least part of the low-voltage switch A2 is accommodated in the switch accommodating deformable portion 210, and a deformation gap 22 is left between the outer wall of the switch accommodating deformable portion 210 and the hole wall of the switch accommodating through hole 200. The switch waterproof pad 21 is made of elastic soft material in this embodiment, and completely covers the low-voltage switch A2 to ensure that the switch waterproof pad 21 can automatically adjust its shape when it is squeezed by external force or the internal pressure changes during use. The deformation gap 22 provides an avoidance space for the deformation of the switch waterproof pad 21, further enhancing the sealing effect, preventing sealing failure caused by temperature changes or mechanical vibrations, and preventing water and solid particles and dust in the environment from entering the switch housing 20, thereby extending the service life of the low-voltage switch A2.

[0043] Specifically, in the present embodiment, the deformation gap 22 is an acute-angle deformation gap, and its shape can be designed according to specific working conditions. At the same time, the deformation gap 22 is directly injection molded when manufacturing the switch housing 20, without the need for subsequent processing, thereby simplifying the processing process.

[0044] In addition, regarding the switch waterproof pad 21, the switch waterproof pad 21 is fixedly connected to the switch housing 20 through a plurality of fasteners 23 distributed on the outer edge of the inner opening of the switch accommodating through hole 200. Under the action of the fasteners 23, the switch waterproof pad 21 can further conform to the inner wall of the switch housing 20 to form a multi-level sealing structure. This design compresses and deforms the edge of the switch waterproof pad 21 through the pressure applied by the evenly distributed fasteners 23, thereby eliminating the assembly gap between the switch waterproof pad 21 and the inner wall of the switch housing 20. The dynamic sealing performance can still be maintained when the low-voltage switch A2 actuator reciprocates, ensuring effective blocking of liquid penetration.

[0045] In this embodiment, the switch housing 20 specifically includes a first switch housing 20-1 and a second switch housing 20-2 that are buckled together. To further ensure sealing and waterproof properties, the outer edge of the switch waterproof pad 21 has a sealing portion 24 embedded in the buckled portion of the first switch housing 20-1 and the second switch housing 20-2. The sealing portion is designed with a tooth structure, such as Figure 7 As shown, its cross section is concave-convex teeth. Specifically, the sealing part 24 is connected to the first switch housing 20-1 through a first concave-convex sealing structure, and the sealing part 24 is connected to the second switch housing 20-2 through a second concave-convex sealing structure. The first switch housing 20-1 and the second switch housing 20-2 are meshed with each other at the buckling surface to ensure that a uniform preload is generated when the switch housing 20 is assembled; in particular, this structure cooperates with the sealing design of the main part of the switch waterproof pad 21 to achieve all-round waterproof protection of the switch housing 20 under static and dynamic conditions.

[0046] Specifically, the first concave-convex sealing structure includes a first sealing groove 25 and a first sealing protrusion 26 that match each other, and any one of the first sealing groove 25 and the first sealing protrusion 26 is provided on the sealing portion 24, and the remaining one is provided on the first switch housing 20-1. In this embodiment, in order to improve production efficiency, the first sealing protrusion 26 is provided on the first switch housing 20-1, and the first sealing groove 25 is provided on the above-mentioned sealing portion 24; similarly, the above-mentioned second concave-convex sealing structure is the same as the first concave-convex sealing structure, and the second concave-convex sealing structure includes a second sealing groove 27 and a second sealing protrusion 28 that match each other, and any one of the second sealing groove 27 and the second sealing protrusion 28 is provided on the sealing portion 24, and the remaining one is provided on the second switch housing 20-2. In this embodiment, the second sealing groove 27 is provided on the sealing portion 24, and the second sealing protrusion 28 is provided on the second switch housing 20-2.

[0047] At the same time, if Figure 8 As shown, the switch box structure further includes a switch contact protection capacitor 29 which is electrically connected to the first cable input line S2 and the first cable output line S respectively and is connected in parallel with the low voltage switch A2.

[0048] The switch contact protection capacitor 29 provides multiple protection functions for the low voltage switch A2, effectively improving the overall performance and reliability of the switch. Its main functions include: The switch contact protection capacitor 29 provides multiple protection functions for the low-voltage switch A2, effectively improving the overall performance and reliability of the switch. When the switch contacts are disconnected, the switch contact protection capacitor 29 can absorb the transient voltage generated between the contacts and reduce the formation of arcs, thereby protecting the contacts from electrical erosion and extending the service life of the switch. At the same time, when the low-voltage switch A2 disconnects the load, the switch contact protection capacitor 29 can absorb the generated reverse electromotive force, suppress voltage spikes, prevent overvoltage between the contacts, and protect the switch and related circuits from damage. The stability and durability of the low-voltage switch A2 in harsh electrical environments are significantly enhanced, while reducing maintenance requirements and improving the reliability of the overall system.

[0050] The structure and principle of this embodiment are basically the same as those of the third embodiment. The different structure is that, with respect to the switch box of the extra-low voltage vibrator rod in the third embodiment, this embodiment describes the relationship between the switch box of the extra-low voltage vibrator rod and the first cable input line and the first cable output line.

[0051] In this embodiment, the two ends of the switch housing 20 in the above-mentioned embodiment 1 are respectively provided with a housing extension tube 201 which is at least partially sleeved on the first cable input line and the first cable output line. A wire sheath 33 is also provided at the connection between the first cable input line S2 and the switch housing 20 in the embodiment 1. The wire sheath 33 is made of a high-performance elastic material (such as a rubber wire sheath) and has good waterproof, dustproof and mechanical stability. One end thereof is sealedly connected to the housing extension tube 201 to ensure that there is no gap at the connection, thereby preventing moisture and dust from entering the interior of the switch housing 20. The other end is tightly sealedly connected to the first cable input line S2. This design not only protects the first cable input line S2 from erosion by the external environment, but also enhances the bending and tensile resistance of the cable. At the same time, during the practical use of the device, the first cable input line S2 will often twist, so the inner diameter of the wire sheath 33 is slightly larger than the diameter of the first cable input line S2.

[0052] Furthermore, in order to ensure that the wire sleeve 33 can be stably fixedly connected to the shell extension tube 201 during use, the wire sleeve 33 is also provided with a first clamping member 35 which enables the wire sleeve 33 to be axially fixed to the shell extension tube 201 and further enables the shell extension tube 201 and the wire sleeve 33 to be sealed and connected. By way of example, the structural design of the first clamping member 35 is similar to a clamp (for example only, including but not limited to), comprising two semicircular hoop bodies, both ends of which are connected by bolts, and the hoop body is contracted by tightening the bolts, thereby achieving tight fixation of the wire sleeve 33 and the shell extension tube 201.

[0053] Regarding the other end of the wire sheath 33, Figure 6As shown, the inner wall of the other end of the cable sheath 33 has an inner convex annular sealing portion 330, which contacts and forms a seal with the outer wall of the first cable input line S2. The inner convex annular sealing portion 330 is in close contact with the outer wall of the first cable input line S2, and the outer wall of the first cable input line S2 is tightly fitted to effectively prevent external moisture, dust and impurities from entering the switch housing 20. Specifically, the inner convex annular sealing portion 330 is made of a flexible and elastic material, such as rubber or silicone, and can automatically adapt to the outer diameter of the first cable input line S2 when it passes through, forming a tight seal.

[0054] Similarly, a second clamp 36 is sleeved on the cable sheath 33 to fix the cable sheath 33 axially to the first cable input line S2 and seal the first cable input line S2 and the cable sheath 33. The structure of the second clamp 36 is similar to the first clamp 35. It is made of high-strength and elastic metal or composite material and can tightly clamp the cable sheath 33 and the first cable input line S2. The connection between the cable sheath 33 and the first cable input line S2 is not only reliably fixed in the axial direction, but also the auxiliary effect of the second clamp 36 further enhances the sealing effect of the inner convex annular sealing portion 330.

[0055] The connection of the first cable output line S is different from that of the first cable input line S2. Specifically, a rubber tube R is sheathed outside the first cable output line S. In this embodiment, the rubber tube R is different from the sheath 33. The rubber tube R needs to completely cover the first cable output line S, while the sheath 33 only partially covers the first cable input line S2. At the same time, in order to ensure the connection stability and sealing of the rubber tube R, the above-mentioned shell extension tube 201 is at least partially inserted into the rubber tube R, and the rubber tube R is also sleeved with a third tightening member 36-2 which makes the rubber tube R axially fixed to the shell extension tube 201 and further makes the shell extension tube 201 and the rubber tube R sealedly connected. The style of the third tightening member 36-2 is the same as that of the above-mentioned first tightening member 35 and the second tightening member 36.

[0056] Embodiment 5

[0057] The present invention also provides a new ultra-low voltage vibrator rod structure powered by a portable mobile power source. In this embodiment, a modulation control box for the ultra-low voltage vibrator rod is added on the basis of the structure of the ultra-low voltage vibrator rod powered by a portable mobile power source in the above embodiment to further improve the scope of use and adaptability of this product.

[0058] In this embodiment, the modulation control box body 3 has the function of modulating the power of ordinary electric tricycles, electric vehicles, etc. into the power form required by the vibration rod, and converting direct current into 50V / 200Hz three-phase alternating current for use in special low-voltage and high-frequency concrete vibration rods.

[0059] like Figure 10-11 As shown, the modulation control box body 3 includes a modulation control housing 31 which is located at the outermost part and is used to accommodate components, and a modulation circuit board 30 which is electrically connected to the external first cable input line S2 is fixedly arranged in the above-mentioned modulation control housing 31. In particular, in this embodiment, a potting glue layer 32 is arranged in the modulation control housing 31, and the above-mentioned modulation circuit board 30 is embedded in the potting glue layer 32, which plays a role of auxiliary fixing and isolation sealing, and the above-mentioned potting glue layer 32 is made of high-performance insulating material, which has good waterproof, moisture-proof, dust-proof and corrosion-resistant properties, and can effectively protect the modulation circuit board 30 from erosion by external environmental factors, thereby extending its service life and ensuring its stable operation. In addition, the filling of the potting glue layer 32 also enhances the overall structural strength of the modulation control box body 3, so that it can withstand a certain degree of external force impact, and further improves the reliability and durability of the product.

[0060] Among them Figure 9-10 As shown, the modulation control housing 31 includes a first housing 310 and a second housing 311 buckled on the opening of the first housing 310. The first housing 310 and the second housing 311 are sealed and connected through an annular protrusion 312 and an annular groove 313 of concave-convex sealing fit. The mutual cooperation of the annular protrusion 312 and the annular groove 313 forms a reliable sealing interface, which effectively prevents external moisture, dust and impurities from entering the modulation control box. Specifically, the first housing 310 and the second housing 311 are both provided with an annular protrusion 312 and annular groove 313. In this embodiment, when the first housing 310 is buckled on the second housing 311, the annular protrusion 312 is inserted into the annular groove 313 to form a tight sealing fit. As a preferred solution, in order to further enhance the sealing effect, an elastic sealing ring or sealant is added between the annular protrusion 312 and the annular groove 313, which can improve the reliability of the seal and compensate for the sealing gap caused by manufacturing tolerance or assembly error to a certain extent.

[0061] In the sealing design of the modulation control box, the sealing connection of the wire sheath 33 plays a key role. The wire sheath 33 is made of high-performance elastic material (such as a rubber wire sheath) and has good waterproof, dustproof and mechanical stability. One end of the wire sheath is sealed and connected to the modulation control housing 31 to ensure that there is no gap at the connection, thereby preventing moisture and dust from entering the interior of the housing. The other end is tightly sealed and connected to the first cable input line S2. This design not only protects the cable from erosion by the external environment, but also enhances the bending and tensile resistance of the cable. At the same time, during the practical use of this device, the first cable input line S2 will often twist, so the inner diameter of the wire sheath 33 is larger than the diameter of the first cable input line S2.

[0062] Specifically, extension tubes 34 are respectively provided on two opposite sides of the modulation control housing 31, one end of the wire sleeve 33 is sleeved on the extension tube 34 and the two are sealed and connected, the extension tube 34 provides a stable installation base for the wire sleeve 33 and enhances the sealing performance. In addition, as an alternative, a threaded ring can be axially arranged on the wall of the extension tube 34 to further improve the sealing between the extension tube 34 and the wire sleeve 33.

[0063] Furthermore, to ensure that the wire sheath 33 can be stably fixedly connected to the extension tube 34 during use, the wire sheath 33 is also provided with a first clamping member 35 which axially fixes the wire sheath 33 to the extension tube 34 and seals the extension tube 34 and the wire sheath 33. By way of example, the structural design of the first clamping member 35 is similar to a clamp (for example only, including but not limited to), comprising two semicircular hoop bodies, both ends of which are connected by bolts, and the hoop body is contracted by tightening the bolts, thereby achieving tight fixation of the wire sheath 33 and the extension tube 34.

[0064] At the same time, an expansion hole 331 is provided at one end of the inner wall of the wire sleeve 33 close to the modulation control housing 31, and the axial length of the extension tube 34 is shorter than the axial length of the expansion hole 331. This design enables the wire sleeve 33 to be smoothly put on the extension tube 34 through the expansion hole 331 when connected to the extension tube 34, and a transition area is formed between the two, thereby providing a larger operating space for sealing and fixing.

[0065] Regarding the other end of the wire sheath 33, Fig. 9 As shown, the inner wall of the other end of the cable sheath 33 has an inner convex annular sealing portion 330, which contacts and forms a seal with the outer wall of the first cable input line S2. The inner convex annular sealing portion 330 is in close contact with the outer wall of the first cable input line S2, and effectively prevents external moisture, dust and impurities from entering the modulation control box. Specifically, the inner convex annular sealing portion 330 is made of a flexible and elastic material, such as rubber or silicone, and can automatically adapt to the outer diameter of the first cable input line S2 when it passes through, forming a tight seal.

[0066] Similarly, a second clamp 36 is sleeved on the cable sheath 33 to fix the cable sheath 33 axially to the first cable input line S2 and seal the first cable input line S2 and the cable sheath 33. The structure of the second clamp 36 is similar to the first clamp 35. It is made of high-strength and elastic metal or composite material and can tightly clamp the cable sheath 33 and the first cable input line S2. The connection between the cable sheath 33 and the first cable input line S2 is not only reliably fixed in the axial direction, but also the auxiliary effect of the second clamp 36 further enhances the sealing effect of the inner convex annular sealing portion 330.

[0067] In addition, regarding the fixing design of the modulation circuit board 30, as shown in FIG. Fig.11 As shown, the modulation circuit board 30 is fixed to the modulation control housing 31 through an overhead fixing structure, and the overhead fixing structure includes a plurality of overhead columns 37 fixed in the modulation control housing 31. The modulation circuit board 30 is placed at the free end of the overhead column 37 and the modulation circuit board 30 is provided with fasteners 38 connected to the overhead column 37. This overhead fixing design not only provides stable support for the modulation circuit board 30, but also ensures that there is a certain space between it and the bottom of the modulation control housing 31, thereby facilitating the heat dissipation of the modulation circuit board 30 and the uniform filling of the potting glue layer 32; the fastener 38 is a screw, bolt or other mechanical connector, which is matched with the mounting hole on the modulation circuit board 30 to firmly fix the modulation circuit board 30 on the overhead column 37. Furthermore, the number and distribution of the overhead columns 37 can be optimized according to the size and weight of the modulation circuit board 30 to ensure that the modulation circuit board 30 can be uniformly supported in all directions. For example, the overhead columns 37 are respectively arranged at the four corners and the center of the modulation circuit board 30, which can effectively improve its fixing stability.

[0069] like Fig.12 As shown, a vibration control system powered by a variety of DC power sources (such as three-wheeled or two-wheeled battery vehicles, lithium batteries or portable mobile power supplies). The low-voltage power plug 4 can be connected to the above various mobile power supplies. After the power is initially converted, the modulation circuit board 30 adjusts the input power to low-voltage and high-frequency AC power to meet the driving requirements of the vibration rod motor. The modulation circuit board 30 has multiple built-in safety mechanisms: 1. Switch detection: If the physical switch is not connected, the modulation circuit board 30 automatically cuts off the output current to ensure that the vibrator is completely silent when there is no operation instruction; 2. Switch activation: After the switch is connected and turned on, the modulation circuit board 30 starts the power supply process, transmits electrical energy to the vibrator motor, and drives it to vibrate at high frequency; 3. Temperature monitoring: The system integrates a working temperature detection module to monitor the temperature rise of the vibrator in real time during operation. If abnormally high temperature is detected, it may trigger overload protection or automatic power off to prevent the motor from burning out.

[0070] In addition, the design of the modulation circuit board 30 ensures the maximum efficiency of power conversion, while the low-voltage and high-frequency characteristics reduce energy consumption and improve the working stability of the vibrator. The overall system achieves safe and efficient power transmission and control through modular design (power input → power conversion → safety control → output execution), which is suitable for industrial or mechanical equipment scenarios that require precise vibration control.

[0073] like Fig.13 As shown, when the low-voltage power plug 4 is connected to a power source (three-phase generator, etc.) to output three-phase AC power, the device does not need to be provided with the modulation control box body 3 in the above embodiment, that is, Fig.13 As shown in , the low-voltage power plug 4 is directly connected to the switch box 2, and the low-voltage power plug 4 can be directly connected to the above-mentioned three-phase AC power supply.
