Description

Technical Field

[0001] The invention relates to the field of dumbbell production, and in particular to a dumbbell production device and a use method. Background Art

[0002] Dumbbells are a simple piece of equipment used to enhance muscle strength training. Their main material is cast iron, and some are covered with a layer of rubber. According to the material and craftsmanship, dumbbells can be divided into the following categories: plastic-dipped dumbbells, rubber-coated dumbbells, paint-coated dumbbells, wooden steel dumbbells and metal dumbbells, etc. Long-term practice with dumbbells can modify muscle lines and increase muscle endurance. Regular exercises with heavy dumbbells can firm muscles, strengthen muscle fibers and increase muscle strength. Among them, the metal dumbbells are made of cast iron as a whole, which are hard, heavy and dense. The surface of the dumbbells is galvanized, which is smooth and refreshing, does not rust or change color, enhances the corrosion resistance of the metal, increases hardness and surface beauty. In the galvanizing process of existing metal dumbbells, the dumbbells to be galvanized are usually directly placed in a holding frame, and then the holding frame is placed in a galvanizing tank. Partitions are inserted and set inside the holding frame to thereby The dumbbells can be placed separately to prevent them from contacting each other and affecting the galvanizing effect; the extended protrusions and the arc-shaped guide rods are arranged in coordination, so that the holding frame can tilt left and right as the connected turntable rotates, thereby driving the dumbbells inside it to roll, thereby changing the contact surface of the dumbbells with the holding frame during the galvanizing process, so that the surface can be evenly galvanized, and the galvanizing efficiency of the dumbbells is also effectively improved. However, in this dumbbell galvanizing method, the galvanizing pool is usually open, especially when the galvanizing is completed, when the holding frame is removed from the galvanizing pool, the galvanizing pool must be in an open setting at this time, which will cause the galvanizing liquid in the galvanizing pool to easily contact with the outside air for a long time, causing the galvanizing liquid in the galvanizing pool to be easily affected by the outside air to cool and solidify, thereby affecting the subsequent galvanizing work.

[0006] Preferably, the driving plate is fixedly connected to the auxiliary bar, and the auxiliary bar is fixedly connected to the elliptical auxiliary block.

[0007] Preferably: a plurality of sets of guide rods 2 are fixedly installed between the top end of the galvanized box and the bracket, the guide rods 2 are slidably passed through the inner side of the top cover, and a plurality of sets of springs 2 are fixedly installed between the top end of the top cover and the bracket.

[0011] Preferably: the lower end of the outer side of the galvanizing box is connected to a discharge pipe, and a high temperature resistant valve is installed on the discharge pipe.

[0012] The present invention also provides a method for producing and using a dumbbell, which is characterized by comprising the following specific steps:

[0013] S1. When in use, add an appropriate amount of galvanizing liquid to the galvanizing box through the feeding pipe, place multiple galvanized dumbbells in different placement cavities of the placement frame and above the blocking plate, then start the electric push rod to drive the placement frame to move down into the galvanizing box, so that the dumbbells placed in the placement frame are moved into the galvanizing liquid for galvanizing;

[0014] S2. During the galvanizing process, the starting motor will drive multiple sets of stirring blades to rotate. The rotation of multiple sets of stirring blades will stir the galvanizing liquid in the galvanizing box, which can alleviate the solidification of the galvanizing liquid in the galvanizing box. At the same time, driven by the motor, multiple sets of sealing moving rods will move back and forth. During the movement of the sealing moving rods, the sealing moving rods will contact the placement frame, and because the lifting frame rotates to connect the two sets of connecting plates, the placement frame will tilt left and right, thereby driving the dumbbell inside it to roll, thereby changing the contact surface of the dumbbell with the placement frame during the galvanizing process, so that its surface can be evenly galvanized, and at the same time, the galvanizing efficiency of the dumbbell is effectively improved;

[0015] S3. During the galvanizing process, since the multiple sets of strong springs at the bottom of the lifting frame will contact the top cover, and since the strong springs are elastic, when the placement frame tilts left and right, the strong springs will be forced to shake up and down, thereby driving the placement frame tilted left and right to move up and down, so that the dumbbells can roll more effectively in the placement frame, further improving the galvanizing efficiency;

[0016] S4. After the galvanizing work is completed, start the electric push rod to drive the placement frame to move up. After the blocking plate at the bottom of the placement frame enters the channel, the two sets of limit blocks will contact the bottom of the top cover. At this time, the electric push rod will drive the placement frame and the top cover to move up at the same time until the electric push rod completes the contraction work. At this time, the top of the blocking plate is just flush with the top of the channel. At this time, the blocking plate blocks the channel to prevent the heat of the galvanizing liquid in the galvanizing box from overflowing in large quantities, and the placement frame is outside the galvanizing box. After that, the operator uses special tools to take the galvanized dumbbells out of the placement frame, and then puts in new galvanized dumbbells to continue the galvanizing work.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. After the galvanizing work is completed, the electric push rod is started to drive the placement frame and the blocking plate to move up until the electric push rod completes the contraction work. At this time, the top of the blocking plate is just flush with the top of the channel. At this time, the blocking plate blocks the channel to prevent the heat of the galvanizing liquid in the galvanizing box from overflowing in large quantities, and the placement frame is outside the galvanizing box, which is convenient for the operator to use special tools to take the galvanized dumbbell out of the placement frame; and before the motor push rod drives the placement frame and the blocking plate to move up, it will first drive the elliptical auxiliary block to move up, and the elliptical auxiliary block passes between the auxiliary plate and the galvanizing box. When the elliptical auxiliary block moves up, it contacts the auxiliary plate through the elliptical auxiliary frame, and through the shape of the elliptical auxiliary block, it will gradually drive the auxiliary plate away from the galvanizing box, thereby making the sealing moving rod away from the placement frame, ensuring that the sealing moving rod will not affect the placement frame from moving up, and also ensuring that when the placement frame completes material taking and discharging and moves down again, the sealing moving rod will not be directly below the blocking plate, ensuring that when the placement frame and the blocking plate move down, the sealing moving rod will not block the placement frame and the blocking plate from moving down.

[0019] 2. When the present invention is in use, starting the motor will drive multiple groups of stirring blades to rotate. The rotation of the multiple groups of stirring blades will stir the galvanizing liquid in the galvanizing box, which can alleviate the solidification of the galvanizing liquid in the galvanizing box. At the same time, the stirring blades stir the galvanizing liquid, so that the galvanizing liquid flows in the sealed space, so that the galvanizing liquid can better galvanize the dumbbells; at the same time, driven by the motor, multiple groups of sealed moving rods will move back and forth. During the movement of the sealed moving rods, the sealed moving rods will contact the placement frame, and because the lifting frame rotates to connect the two groups of connecting plates, the placement frame will be moved. It tilts left and right, thereby driving the dumbbell inside it to roll, thereby changing the contact surface of the dumbbell with the placement frame during the galvanizing process, so that the surface can be evenly galvanized, and at the same time, the galvanizing efficiency of the dumbbell is effectively improved; and in the galvanizing process, since the multiple groups of strong springs at the bottom of the lifting frame will contact the top cover, and since the strong springs are elastic, when the placement frame tilts left and right, the strong springs will be forced to shake up and down, thereby driving the tilted placement frame up and down, so that the dumbbell can roll more effectively in the placement frame, further improving the galvanizing efficiency.

Multiple groups of springs 1 2203 are fixedly installed between the auxiliary plate 2202 and the outer wall of the galvanizing box 1. The outer side of the auxiliary plate 2202 is movably fitted with an elliptical wheel 2204, and the elliptical wheel 2204 is fixedly connected to a rotating shaft 2205.

[0029] The driving plate 5 is fixedly connected to the auxiliary strip 24, and the auxiliary strip 24 is fixedly connected to the elliptical auxiliary block 25. After the galvanizing work is completed, the motor 19 needs to be stopped. At this time, the sealing moving rod 2201 will stop moving, but it cannot be guaranteed that the sealing moving rod 2201 is away from the placement frame 11. At this moment, the electric push rod 4 drives the driving plate 5 to move upward. The upward movement of the driving plate 5 will drive the auxiliary strip 24 and the two groups of connecting columns 6 to move upward. The upward movement of the auxiliary strip 24 will drive the elliptical auxiliary block 25 to move upward, and the elliptical auxiliary block 25 passes between the auxiliary plate 2202 and the galvanizing box 1. When the elliptical auxiliary block 25 moves upward, it contacts the auxiliary plate 2202 through the elliptical auxiliary frame 25, and through the shape of the elliptical auxiliary block 25, it will gradually drive the auxiliary plate 2202 is away from the galvanizing box 1, so that the sealing moving rod 2201 is away from the placing frame 11, ensuring that the sealing moving rod 2201 will not affect the upward movement of the placing frame 11, and also ensuring that when the placing frame 11 moves down again after completing material picking and placing, the sealing moving rod 2201 will not be directly below the blocking plate 12, ensuring that when the placing frame 11 and the blocking plate 12 move down, the sealing moving rod 2201 will not block the placing frame 11 and the blocking plate 12 from moving down; when the bottom of the elliptical auxiliary block 25 is higher than the auxiliary plate 2202, the top of the two sets of circular abutment plates 7 will just abut the lifting frame 8; during galvanizing, the top of the elliptical auxiliary block 25 is lower than the auxiliary plate 2202, ensuring that the auxiliary plate 2202 will not touch the elliptical auxiliary block 25 when moving back and forth.

[0030] A plurality of sets of guide rods 26 are fixedly installed between the top of the galvanizing box 1 and the bracket 3, and the guide rods 26 all slide through the inner side of the top cover 9, and a plurality of sets of springs 27 are fixedly installed between the top of the top cover 9 and the bracket 3; the guide rods 26 are arranged so that the top cover 9 can stably move up and down; when the galvanizing process is completed, the electric push rod 4 is started to drive the placement frame 11 to move up, and after the blocking plate 12 at the bottom of the placement frame 11 enters the channel 2, the two sets of limit blocks 14 will contact the bottom of the top cover 9, and the electric push rod 4 will simultaneously drive the placement frame 11 and the top cover 9 to move up until the electric push rod 4 completes the contraction work, and the top cover 9 moves up to open the top of the channel 2, but at this time the blocking plate 12 enters the channel 2, and the heat of the galvanizing liquid in the galvanizing box 1 will not overflow in large quantities; when the top cover 9 moves up away from the top of the channel 2, the springs 27 will be gradually squeezed.

[0031] The blocking plate 12 matches the inner cavity of the channel 2, and the bottom of the blocking plate 12 is fixedly connected to the weight bar 13; after the galvanizing work is completed and the sealing moving rod 2201 is away from the placement frame 11, it is affected by the weight of the weight bar 13, and the weight bar 13 is directly below the blocking plate 12, ensuring that the blocking plate 12 will not tilt, so that the channel 2 can be blocked when the blocking plate 12 moves up.

[0033] A feeding pipe 30 is installed through the inner side of the galvanizing box 1 , and a sealing cover is threadedly connected to the pipe opening of the feeding pipe 30 on the outer side of the galvanizing box 1 ; when in use, an appropriate amount of galvanizing liquid can be added to the galvanizing box 1 through the feeding pipe 30 .

[0035] The present invention also provides a method for producing and using a dumbbell, which is characterized by comprising the following specific steps:

[0036] S1. When in use, add an appropriate amount of galvanizing liquid to the galvanizing box 1 through the feeding pipe 30, place multiple galvanized dumbbells in different placement cavities of the placement frame 11 and above the blocking plate 12, then start the electric push rod 4 to drive the placement frame 11 to move down into the galvanizing box 1, so that the dumbbells placed in the placement frame 11 are moved into the galvanizing liquid for galvanizing;

[0037] S2. During the galvanizing process, starting the motor 19 will drive the multiple groups of stirring blades 17 to rotate. The rotation of the multiple groups of stirring blades 17 will stir the galvanizing liquid in the galvanizing box 1, which can alleviate the solidification of the galvanizing liquid in the galvanizing box 1. At the same time, driven by the motor 19, multiple groups of sealing moving rods 2201 will move back and forth. During the movement of the sealing moving rods 2201, the sealing moving rods 2201 will contact the placement frame 11, and because the lifting frame 8 rotates to connect the two groups of connecting plates 10, the placement frame 11 tilts left and right, thereby driving the dumbbell inside it to roll, thereby changing the contact surface of the dumbbell with the placement frame 11 during the galvanizing process, so that its surface can be evenly galvanized, and at the same time, the galvanizing efficiency of the dumbbell is effectively improved;

[0038] S3. During the galvanizing process, since the multiple groups of strong springs 15 at the bottom of the lifting frame 8 will contact the top cover 9, and since the strong springs 15 are elastic, during the process of the placement frame 11 tilting left and right, the strong springs 15 will be forced to shake up and down, thereby driving the placement frame 11 tilted left and right to move up and down, so that the dumbbell can roll more effectively in the placement frame 11, further improving the galvanizing efficiency;

[0039] S4. After the galvanizing work is completed, start the electric push rod 4 to drive the placement frame 11 to move up. After the blocking plate 12 at the bottom of the placement frame 11 enters the channel 2, the two sets of limit blocks 14 will contact the bottom of the top cover 9. At this time, the electric push rod 4 will simultaneously drive the placement frame 11 and the top cover 9 to move up until the electric push rod 4 completes the contraction work. At this time, the top of the blocking plate 12 is just flush with the top of the channel 2. At this time, the blocking plate 12 blocks the channel 2 to prevent the heat of the galvanizing liquid in the galvanizing box 1 from overflowing in large quantities, and the placement frame 11 is outside the galvanizing box 1. After that, the operator uses special tools to take the galvanized dumbbells out of the placement frame 11, and then puts in new galvanized dumbbells to continue the galvanizing work.

[0040] Working principle of the present invention: when in use, add an appropriate amount of galvanizing liquid to the galvanizing box 1 through the feeding pipe 30, place a plurality of galvanized dumbbells in different placement cavities of the placement frame 11 and above the blocking plate 12, then start the electric push rod 4 to drive the driving plate 5 to move downward, the driving plate 5 moves downward, and the lifting frame 8 is gradually moved downward under the action of the weight of the weight bar 13 and the like, and the lifting frame 8 moves downward, and the lifting frame 8 moves downward to drive the placement frame 11 to move downward, and in this process, the top cover 9 will also move downward until the telescopic end of the electric push rod 4 is fully extended, at which time the top cover 9 just blocks the top of the channel 2, and the two sets of round abutment plates 7 just abut the top cover 9, so that the top cover 9 can stably block the top of the channel 2, and at this time the placement frame 11, the blocking plate 12, and the connecting plate 10 pass through the channel 2 and enter the inner cavity of the galvanizing box 1, at which time the placement frame 11 is in the galvanizing liquid, so that the dumbbells are placed in the galvanizing liquid for galvanizing;

[0041] During the galvanizing process, the motor 19 is started and the two sets of sprocket wheels 20 and the chain 21 are driven to rotate the two sets of stirring rods 16. The rotation of the stirring rods 16 will drive the multiple sets of stirring blades 17 to rotate. The rotation of the multiple sets of stirring blades 17 will stir the galvanizing liquid in the galvanizing box 1, which can alleviate the solidification of the galvanizing liquid in the galvanizing box 1. During the galvanizing process, a set of stirring rods 16 fixedly connected to the sprocket wheel 2207 rotates under the transmission of the two sets of sprocket wheels 2207 and the chain 2208, which will drive the rotating shaft 2205 to rotate. The rotation of the rotating shaft 2205 will drive the elliptical wheel 2204 to rotate. Since the elliptical wheel 2204 contacts the auxiliary plate 2202 and under the elastic action of the multiple sets of springs 2203, the auxiliary plate 2202 will move back and forth. The back and forth movement of the auxiliary plate 2202 will drive the multiple sets of sealing moving rods 2 201 moves back and forth. During the movement of the sealing moving rod 2201, the sealing moving rod 2201 will contact the placement frame 11, and because the lifting frame 8 rotates to connect the two sets of connecting plates 10, the placement frame 11 is tilted left and right, thereby driving the dumbbell inside it to roll, thereby changing the contact surface of the dumbbell with the placement frame 11 during the galvanizing process, so that its surface can be uniformly galvanized, and at the same time, the galvanizing efficiency of the dumbbell is effectively improved; and during the galvanizing process, since the multiple sets of strong springs 15 at the bottom of the lifting frame 8 will contact the top cover 9, and since the strong springs 15 are elastic, during the process of the placement frame 11 tilting left and right, the strong springs 15 will be forced to shake up and down, thereby driving the tilted placement frame 11 to move up and down, so that the dumbbell can roll more effectively in the placement frame 11, further improving the galvanizing efficiency;

[0042] When the galvanizing process is completed, after the galvanizing work is completed, it is necessary to stop the motor 19, and the sealing moving rod 2201 will stop moving at this time, but it cannot be guaranteed that the sealing moving rod 2201 is away from the placement frame 11 at this time. At this moment, the electric push rod 4 drives the driving plate 5 to move up, and the driving plate 5 moves up to drive the auxiliary strip 24 and the two sets of connecting columns 6 to move up, and the auxiliary strip 24 moves up to drive the elliptical auxiliary block 25 to move up, and the elliptical auxiliary block 25 passes between the auxiliary plate 2202 and the galvanizing box 1. When the elliptical auxiliary block 25 moves up, it contacts the auxiliary plate 2202 through the elliptical auxiliary frame 25, and through the elliptical auxiliary The shape of the block 25 will gradually drive the auxiliary plate 2202 away from the galvanizing box 1, and then make the sealing moving rod 2201 away from the placement frame 11, ensuring that the sealing moving rod 2201 will not affect the upward movement of the placement frame 11, and also ensuring that when the placement frame 11 moves down again after completing material collection and discharge, the sealing moving rod 2201 will not be directly below the blocking plate 12, ensuring that when the placement frame 11 and the blocking plate 12 move down, the sealing moving rod 2201 will not block the placement frame 11 and the blocking plate 12 from moving down; when the bottom of the elliptical auxiliary block 25 is higher than the auxiliary plate 2202, at this time, the tops of the two sets of circular abutment plates 7 will just abut against the lifting frame 8;

[0043] After that, the upward movement of the driving plate 5 will drive the lifting frame 8 to move upward, and the upward movement of the lifting frame 8 will drive the placement frame 11 and the blocking plate 12 to move upward. When the blocking plate 12 at the bottom of the placement frame 11 enters the channel 2, the two sets of limit blocks 14 will contact the bottom of the top cover 9. At this time, the electric push rod 4 will simultaneously drive the placement frame 11 and the top cover 9 to move upward until the electric push rod 4 completes the contraction work. At this time, the top of the blocking plate 12 is just flush with the top of the channel 2. At this time, the blocking plate 12 blocks the channel 2 to prevent the heat of the galvanizing liquid in the galvanizing box 1 from overflowing in large quantities, and the placement frame 11 is outside the galvanizing box 1. After that, the operator uses special tools to take the galvanized dumbbell out of the placement frame 11, and then puts in a new galvanized dumbbell to continue the galvanizing work.

[0044] It should be noted that the device of the present invention requires an external suitable power supply and controller when in use. The external power supply provides power support for the operation of the motor 19 and the electric push rod 4, and the operation of the motor 19 and the electric push rod 4 can be controlled by an external lower controller; it should be noted that the motor 19 uses a motor that does not have a self-locking function.

When in use, a proper amount of galvanizing liquid is added to the galvanizing box (1) through the feeding pipe (30), and a plurality of galvanized dumbbells are placed in different placement chambers of the placement frame (11) and above the blocking plate (12), and then the electric push rod (4) is started to drive the placement frame (11) to move downward into the galvanizing box (1), so that the dumbbells placed in the placement frame (11) are moved into the galvanizing liquid for galvanizing; S2. During the galvanizing process, the starting motor (19) will drive the plurality of stirring blades (17) to rotate. The rotation of the plurality of stirring blades (17) will stir the galvanizing liquid in the galvanizing box (1), thereby alleviating the solidification of the galvanizing liquid in the galvanizing box (1). At the same time, the motor (19) will drive the plurality of sealing moving rods (2201) to move back and forth. During the movement of the sealing moving rods (2201), the sealing moving rods (2201) will contact the placement frame (11). Since the lifting frame (8) rotates to connect the two sets of connecting plates (10), the placement frame (11) will tilt left and right, thereby driving the dumbbell inside the dumbbell to roll, thereby changing the contact surface of the dumbbell with the placement frame (11) during the galvanizing process, so that the surface can be evenly galvanized, and at the same time, the galvanizing efficiency of the dumbbell is effectively improved. S3. During the galvanizing process, since the multiple groups of strong springs (15) at the bottom of the lifting frame (8) will contact the top cover (9), and since the strong springs (15) are elastic, during the process of the placement frame (11) tilting left and right, the strong springs (15) will be forced to shake up and down, thereby driving the placement frame (11) tilted left and right to move up and down, so that the dumbbell can roll more effectively in the placement frame (11), further improving the galvanizing efficiency; S4. After the galvanizing work is completed, the electric push rod (4) is started to drive the placement frame (11) to move upward. After the blocking plate (12) at the bottom of the placement frame (11) enters the channel (2), the two sets of limit blocks (14) will contact the bottom of the top cover (9). At this time, the electric push rod (4) will simultaneously drive the placement frame (11) and the top cover (9) to move upward until the electric push rod (4) completes the contraction work. At this time, the top of the blocking plate (12) is just flush with the top of the channel (2). At this time, the blocking plate (12) blocks the channel (2) to prevent the heat of the galvanizing liquid in the galvanizing box (1) from overflowing in large quantities, and the placement frame (11) is outside the galvanizing box (1). Then, the operator uses a special tool to take the galvanized dumbbell out of the placement frame (11), and then puts in a new galvanized dumbbell to continue the galvanizing work.
