Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Example 1

[0026] like Figures 1-6 As shown, a movable sound insulation box includes: a mobile cart 1, a fixed box 101 installed on one side of the top of the mobile cart 1, a matching movable box 102 is provided on one side of the fixed box 101, a generator 103 is arranged on the top of the mobile cart 1, and the generator 103 is located inside the fixed box 101, a motor shaft 104 is provided on one side of the outer end of the generator 103, a pulley 105 installed on the outer end of the motor shaft 104, a disassembly and assembly component arranged between the fixed box 101 and the movable box 102, which is used to disassemble and assemble the movable box 102, and a reinforcement component arranged on both sides of the outer end of the mobile cart 1, which is used to reinforce the placement of the mobile cart 1.

[0027] Among them, reference Figure 2-Figure 4 The disassembly and assembly components include: a socket 106, an arc-shaped groove 107, a fixing rod 108, a fixing ball 109 and a handle 110. The four sides of the outer end of the fixed box 101 are respectively provided with sockets 106, and the inside of the sockets 106 are provided with arc-shaped grooves 107. The four sides of the outer end of the movable box 102 are respectively installed with fixing rods 108, and the outer ends of the fixing rods 108 are installed with fixing balls 109 used in conjunction with the arc-shaped grooves 107, and the fixing balls 109 are made of rubber material. A handle 110 is installed on the side of the outer end of the movable box 102 away from the fixing balls 109.

[0028] When the generator 103 is in use, the generator 103 is installed on the mobile cart 1 so that one end of the generator 103 is located inside the fixed box 101, and the movable box 102 is placed on one side of the fixed box 101, so that the sliders 112 on both sides of the bottom of the movable box 102 are placed inside the slide rails 111, and the handle 110 is grasped to push the movable box 102 toward the fixed box 101. At this time, the fixed balls 109 on the four sides of the outer end of the movable box 102 are inserted from the socket 106, and the fixed balls 109 are inserted into the socket 106 and engaged with the arc groove 107. The generator 103 is surrounded and blocked on the mobile cart 1 by the fixed box 101 and the movable box 102, which is convenient for sound insulation of the noise generated by the operation of the generator 103.

[0029] When the generator 103 is damaged during use, the user grabs the handle 110 and pulls the movable box 102, pulling the movable box 102 away from the fixed box 101. After the movable box 102 is subjected to tension, the fixed ball 109 is pulled out from the arc groove 107 and the socket 106, that is, the slider 112 at the bottom of the movable box 102 slides out from the slide rail 111, making it easy to remove the movable box 102 from the fixed box 101, exposing the generator 103, and facilitating the maintenance of the generator 103. There is no need to pull the generator 103 back and forth to move it out or push it into the fixed box 101, thus saving time and effort during maintenance.

[0030] Since the structural shapes of the arc groove 107 and the fixing ball 109 are adapted to each other, and the fixing ball 109 is made of rubber material, when the fixing ball 109 is pushed into the arc groove 107 by force, the fixing ball 109 can be slightly deformed and stuck into the arc groove 107. When the fixing ball 109 is not pulled by external force, the fixing ball 109 can be tightly stuck in the arc groove 107, thereby fixing the movable box 102 to the outer end of the fixed box 101.

[0031] Among them, reference figure Figure 1 、 Figure 3 and Figure 5 A sleeve 113 is provided on one side of the outer end of the generator 103, and the motor shaft 104 is located inside the sleeve 113. An arc hole a114 is opened on one side of the outer end of the fixed box 101, and an arc hole b115 is opened at the relative position between the outer end of the movable box 102 and the arc hole a114.

[0032] When the movable box 102 moves toward the fixed box 101, its sleeve 113 is stuck in the arc hole a114 and protrudes from the outside of the fixed box 101. When the movable box 102 and the fixed box 101 are fitted and docked, the arc hole b115 just covers the other side of the sleeve 113, and the arc hole b115 and the arc hole a114 complete the docking. When the generator 103 is surrounded and blocked inside the movable box 102 and the fixed box 101, the sleeve 113, the motor shaft 104 and the pulley 105 of the generator 103 can be exposed outside the movable box 102 and the fixed box 101, and the arc hole b115 and the arc hole a114 clamp the sleeve 113, and the motor shaft 104 is located inside the sleeve 113, which will not affect the normal rotation and use of the motor shaft 104.

[0033] Among them, reference Figure 2 The interior of the fixed box 101 and the movable box 102 are both adhered with a sound insulation layer 2 by glue, and a plurality of sound absorbing wedges 201 are provided on the inner side of the sound insulation layer 2.

[0034] After the generator 103 is surrounded and isolated inside the movable box 102 and the fixed box 101, the noise generated by the generator 103 when working inside the movable box 102 and the fixed box 101 can be silenced by the sound insulation layer 2 and the sound-absorbing wedge 201, thereby reducing the noise of the generator 103 from propagating outward and avoiding affecting the lives of surrounding residents.

[0035] Among them, reference Figure 1-Figure 3 A connecting pipe 3 is provided on one side of the top of the generator 103, and a smoke exhaust pipe 301 is provided on the top of the connecting pipe 3. A through hole a4 is provided on one side of the top of the fixed box 101, and a through hole b5 is provided on one side of the top of the movable box 102. Sealing rings 6 are installed inside the through holes a4 and b5, and the smoke exhaust pipe 301 passes through the sealing ring 6 and is connected to the connecting pipe 3. A heat dissipation pipe 7 is provided inside the through hole b5, and the heat dissipation pipe 7 fits tightly with the sealing ring 6.

[0036] After the movable box 102 is installed and docked with the fixed box 101, the exhaust pipe 301 is inserted into the fixed box 101 from the through hole a4, so that one end of the exhaust pipe 301 is inserted into the connecting pipe 3 on the top of the generator 103, and the exhaust pipe 301 located in the through hole a4 is tightly sealed by the sealing ring 6, so that the smoke generated by the generator 103 can be discharged from the exhaust pipe 301, and the heat dissipated inside the movable box 102 and the fixed box 101 can be discharged from the heat dissipation pipe 7, and when the heat dissipation pipe 7 is in use, it fits tightly with the sealing ring 6 inside the through hole b5, ensuring that the movable box 102 and the fixed box 101 are tightly sealed, which can effectively soundproof the generator 103.

[0037] Among them, reference Figure 1 and Figure 3 , slide rails 111 are respectively provided on both sides of the top of the mobile cart 1 and are opposite to the bottom of the fixed box 101 , and sliders 112 slidably connected to the slide rails 111 are respectively installed on both sides of the bottom of the movable box 102 .

[0038] When the movable box 102 is assembled and disassembled from the fixed box 101 , the slider 112 at the bottom of the movable box 102 is slidably connected to the slide rail 111 during the process of pulling the movable box 102 , thereby preventing wear between the movable box 102 and the mobile cart 1 .

[0039] Example 2

[0040] Based on Example 1, Figure 1 、 Figure 2 、 Figure 3 and Figure 6The reinforcement components include: a fixed plate 116, a screw hole 117, an adjusting screw 118, a hand crank 119, a connecting plate 120, a reinforcement block 121, a damper 122 and a buffer spring 123. Fixed plates 116 are respectively installed on both sides of the outer end of the mobile cart 1. A screw hole 117 is opened in the middle of the top of the fixed plate 116. The adjusting screw 118 is threadedly connected inside the screw hole 117. A hand crank 119 is welded to the outside of the adjusting screw 118. A connecting plate 120 is welded to the bottom of the adjusting screw 118. A reinforcement block 121 is provided at the bottom of the connecting plate 120. Several dampers 122 are installed between the reinforcement block 121 and the connecting plate 120. Buffer springs 123 are provided between the several dampers 122 and the connecting plate 120.

[0041] After the generator 103 is installed on the mobile cart 1 and surrounded by the movable box 102 and the fixed box 101, it is supported and placed by the mobile wheels at the bottom of the mobile cart 1 and locked by the brake pedal on the outside of the mobile wheel to prevent the mobile wheel from moving. On the basis of locking the mobile wheel, the hand crank 119 is grasped by hand and the adjusting screw 118 is rotated clockwise inside the screw hole 117, so that the adjusting screw 118 drives the connecting plate 120, the reinforcement block 121, the damper 122 and the buffer spring 123 to move downward, and the reinforcement block 121 will contact the ground, adding a reinforcement force to support the placement of both sides of the outer end of the mobile cart 1. When the vibration generated by the generator 103 is transmitted to the mobile cart 1 and the fixed plate 116, the vibration force generated is reduced by the damper 122 and the buffer spring 123 between the connecting plate 120 and the reinforcement block 121, so that the mobile cart 1 is placed stably, thereby improving the overall stability of the mobile cart 1.
