Description

Technical Field

[0001] The utility model relates to the technical field of chain removers and discloses a stacking roller chain chain remover. Background Art

[0002] Roller chain is a type of chain drive used to transmit mechanical power. It is widely used in household, industrial and agricultural machinery, including conveyors, plotters, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers linked together and driven by a gear called a sprocket. It is a simple, reliable and efficient power transmission device.

[0003] The stacking roller chain is disassembled by manually turning the shaft handle, using the thrust generated by the rotation of the thread to push the ejector with the waist groove screw, and the ejector ejects the connecting pin shaft in the center of the chain roller, thereby achieving the purpose of disassembling and cutting the chain. However, when the existing chain remover rotates the screw, the ejector pin rotates with the screw rod, and produces relative movement with the pin shaft of the chain, which is easy to slide eccentrically in the axial direction, which can easily cause the ejector pin or the chain pin shaft to deviate and cause the ejector pin to bend or break.

[0004] Therefore, a kind of accumulation roller chain chain remover with limiting function is needed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing chain remover that when the screw is rotated, the ejector pin follows the screw to rotate, produces relative movement with the chain pin, is prone to sliding eccentricity in the axial direction, and easily causes the ejector pin or the chain pin to deflect and cause the ejector pin to bend or break, the utility model provides an accumulation roller chain remover with a limiting function.

[0009] Further, it further includes: a mounting block fixedly connected to the bottom of the base; a fixing rod rotatably arranged on the mounting block; a rotating gear disc provided on the fixing rod; a toothed ring fixedly connected to the second handle, and the toothed ring meshes with the rotating gear disc; a torsion spring piece wound inside the rotating gear disc.

[0010] Further, it further includes: two guiding rods fixedly connected to the front side of the concave bracket; a centering sleeve slidably arranged on the two guiding rods together; a wedge block provided on the top of the centering sleeve; two third elastic members sleeved on the guiding rods, and the two ends of the third elastic member are respectively connected to the centering sleeve and the guiding rod.

[0011] Further, it further includes: an anti-slip pad embedded on the inner wall of the clamping block.

[0012] Further, it further includes: a bracket fixedly connected to the front side of the sliding fixed seat; a storage box fixedly connected to the bracket.

[0013] Compared with the prior art, the utility model provides a stacking roller chain chain breaker, which has the following beneficial effects: 1. By inserting the limit pin into the base, the limit pin penetrates through the waist-grooved screw ejector, so that when the handle is rotated, it will not rotate with the screw shaft with internal threads, thereby avoiding the relative position sliding deviation between the ejector and the chain pin during the ejection process, and avoiding the bending or breaking of the ejector caused by the rotational sliding deviation.

[0014] 2. The torsion spring piece drives the gear disc to drive the toothed ring to reverse, so that the second handle reverses to drive the screw shaft with internal threads to rotate, and then the waist-grooved screw ejector moves backward to reset, thereby achieving the purpose of automatic reset.

[0015] 3. When the third elastic member returns to its original state, the centering sleeve moves backward to sleeved on the roller, so that the roller is centered and aligned with the waist-grooved screw ejector, and then cooperates with the clamping mechanism to fix both ends of the pin, thereby avoiding the eccentricity of the pin.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: A chain breaker for stacked roller chains. Please refer to Figures 1-7 , which includes: a first handle 1, a base 2, a limit seat 201, a second handle 3, an internally threaded rotating shaft 4, a waist-grooved screw ejector 5, a shaft seat retaining ring 501, and a bearing 6. A base 2 is fixedly connected to the first handle 1. The base 2 is provided with a limit seat 201. A bearing 6 is arranged inside the base 2. An internally threaded rotating shaft 4 is rotatably arranged by two bearings 6. A shaft seat retaining ring 501 is installed on the bearing 6. A second handle 3 is fixedly connected to the outside of the internally threaded rotating shaft 4. A waist-grooved screw ejector 5 is arranged inside the internally threaded rotating shaft 4 in a threaded manner. The waist-grooved screw ejector 5 penetrates through the two bearings 6. A limit pin 7 is slidably arranged on the base 2. The limit pin 7 penetrates through the waist-grooved screw ejector 5. Two rotating rods 10 are fixedly arranged on the front side of the base 2. A clamping block 9 is rotatably arranged on the rotating rods 10. A first elastic member 11 is connected between the two clamping blocks 9. A connecting block 14 is fixedly connected to the front side of the base 2. A sliding seat 12 is slidably arranged on the connecting block 14. A concave bracket 8 is fixedly connected to the sliding seat 12. A sliding fixing seat 13 is fixedly connected to the front side of the sliding seat 12. A clamping rod 15 is slidably arranged on the right side of the sliding fixing seat 13. The contact surface between the clamping rod 15 and the connecting block 14 is a slope. The clamping rod 15 is clamped with the connecting block 14. Two second elastic members 16 are connected between the clamping rod 15 and the sliding fixing seat 13. An anti-slip pad 25 is embedded on the inner wall of the clamping block 9. The anti-slip pad 25 increases the friction between the stacked roller chain and the clamping block 9. A support 26 is fixedly connected to the front side of the sliding fixing seat 13. A storage box 27 is fixedly connected to the support 26. The ejected pin drops into the storage box 27, so as to facilitate the centralized collection of the pins and avoid losing the pins.

[0027] When it is necessary to disassemble the stacked roller chain, first insert the limit pin 7 into the base 2. The limit pin 7 penetrates through the waist-grooved screw ejector 5. Then, when rotating the handle, it will not rotate with the internally threaded rotating shaft, so as to avoid relative position sliding and offset with the chain pin during the ejection process, and avoid bending or breaking of the ejector due to rotational sliding and offset. Place the stacked roller chain on the concave bracket 8 so that the stacked roller chain contacts the clamping block 9, and then squeeze the clamping block 9 to rotate towards the side away from each other. The first elastic member 11 is stretched accordingly. After the stacked roller chain is placed, the first elastic member 11 returns to its original state to make the clamping block 9 rotate towards the side close to each other, and then clamp the stacked roller chain, so as to prevent the pin from moving radially and achieve a positioning effect, and avoid the phenomenon of bending or breaking of the ejector due to pin eccentricity. Then rotate the second handle 3 to make the internally threaded rotating shaft 4 rotate to drive the waist-grooved screw ejector 5 to move forward, and then eject the pin, thus completing the disassembly of the stacked roller chain.

[0028] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 6, a mounting block 17 is fixedly connected to the bottom of the base 2. A fixing rod 18 is rotatably arranged on the mounting block 17. The fixing rod 18 is provided with a rotating gear disk 19. A gear ring 1901 is fixedly connected to the second handle 3. The gear ring 1901 meshes with the rotating gear disk 19. A torsion spring piece 20 is wound inside the rotating gear disk 19.

[0029] When disassembling the stacked roller chain, rotate the second handle 3 to make the gear ring 1901 rotate. The rotation of the gear ring 1901 drives the rotation of the rotating gear disk 19, thereby making the torsion spring piece 20 in a state of storing energy. After the pin shaft is pushed out, release the second handle 3. The torsion spring piece 20 drives the gear disk to drive the gear ring 1901 to reverse, making the second handle 3 reverse to drive the internally threaded rotating shaft 4 to rotate, and then making the waist-grooved screw ejector 5 move backward to reset, so as to achieve the purpose of automatic reset.

[0030] Please refer to Figure 7 and Figure 8 , two guide rods 23 are fixedly connected to the front side of the concave bracket 8. A centering sleeve 22 is slidably arranged on the two guide rods 23 together. The centering sleeve 22 is made of rubber, and the rubber has good internal wear resistance, thereby prolonging the service life of the centering sleeve 22. A wedge block 21 is arranged on the top of the centering sleeve 22. Two third elastic members 24 are sleeved on the guide rods 23. The two ends of the third elastic member 24 are respectively connected to the centering sleeve 22 and the guide rod 23.

[0031] When placing the stacked roller chain, move the stacked roller chain above the wedge block 21, and then press the roller downward to make the roller squeeze the wedge block 21 to move forward, thereby driving the centering sleeve 22 to move forward. The third elastic member 24 is compressed accordingly. When the roller no longer squeezes the wedge block 21, the third elastic member 24 returns to its original state to make the centering sleeve 22 move backward to sleeve on the roller, so that the roller is centered and aligned with the waist-grooved screw ejector 5, and then cooperates with the clamping mechanism to fix both ends of the pin shaft, thereby avoiding the eccentricity of the pin shaft.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
