Abstract
The utility model relates to an electric tricycle chain elasticity adjuster and the utility model is characterized in that the adjuster comprises a sliding plate, a sliding plate base and an adjusting screw rod; the sliding plate is equipped with a chain transmission device and the sliding plate can slide relative to the sliding plate base; the sliding distance of the sliding plate relative to the sliding plate base is adjusted by the adjusting screw rod. The utility model also comprises a bolt which is used for fixing the sliding plate; the sliding plate base is equipped with a long slot in which the sliding plate can be inserted and the sliding plate can slide along the slot; the sliding plate is equipped with a mounting hole and an adjusting screw cap is screwed on. By adopting the structure, the adjusting screw rod can drive the sliding plate and the chain transmission device which is arranged on the sliding plate to slide; because the chain transmission device is equipped with a chain, the sliding distance of the chain transmission device can be used for adjusting the chain elasticity; moreover, the bolt is used for fixing the sliding plate in order to better fix the sliding plate and ensure the stability of the chain transmission device.
Description
Technical field
The utility model belongs to a kind of chain slack adjuster, belongs to a kind of electro-tricycle chain slack adjuster particularly.
Background technique
Chain is the requisite parts of electro-tricycle transmission at present, after but the chain of electro-tricycle is used a period of time, often loose sagging, sometimes also can cause chain releasing, general common processing method is that chain is taken off one section, perhaps changes a new chain, perhaps the screw of tricycle motor is unscrewed, mobile motor is regulated, and these three kinds of methods waste time and energy, and is difficult for changing.Because of a little, developing a kind of regulator that can conveniently regulate the chain degree of tightness is the active demand of electro-tricycle industry.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of electro-tricycle chain slack adjuster simple in structure, easy to use is provided.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of electro-tricycle chain slack adjuster, it is characterized in that: it comprises slide plate, slide plate chair and adjusting screw rod, chain transmission is installed on the slide plate, slide plate can be relatively and slide plate chair slide, slide plate is regulated by adjusting screw rod with the distance of slide plate chair slip relatively.
In order to solve the problems of the technologies described above, the utility model adopts following further technological scheme:
It also is provided with the bolt that is used for fixing slide plate.
Described slide plate chair is provided with the elongated slot that slide plate can insert and slide.
Described slide plate is provided with mounting hole, and an end of described slide plate chair is provided with fixed dam, and baffle plate is provided with through hole, and adjusting screw rod passes through hole and mounting hole successively, screws on the adjusting nut.
After adopting said structure: can make slide plate slides by adjusting screw rod, and drive chain transmission mounted thereto and slide, because chain is installed on the chain transmission, so sliding, chain transmission produces the purpose that distance just can reach adjusting chain degree of tightness, in order better slide plate to be fixed, assurance chain transmission stability, with bolt that slide plate is fastening.
Description of drawings
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.
Fig. 2 is the structural representation of the utility model after equipped.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of electro-tricycle chain slack adjuster, it comprises slide plate 1, slide plate chair 2 and adjusting screw rod 3, chain transmission 4 is installed on the slide plate 1, chain transmission 4 comprises motor etc., the chain (not shown) is housed on the chain transmission 4, slide plate 1 can be relatively and slide plate chair 2 slide, the distances that slide plate 1 slides with slide plate chair 2 relatively are by adjusting screw rod 3 adjustings.In the present embodiment, slide plate chair 2 is provided with two siding tracks 5, siding track 5 is provided with the elongated slot 6 that slide plate 1 can insert and slide, and slide plate 1 is provided with mounting hole 8, and an end of slide plate chair 2 is provided with fixed dam 9, baffle plate 9 is provided with through hole 10, adjusting screw rod 3 passes through hole 10 and mounting hole 8 successively, screws on to regulate nut 11, in order better slide plate to be fixed, guarantee the stability of chain transmission 4, with bolt 7 that two siding tracks 5 and slide plate 1 are fastening.
During use, chain transmission 4 is installed on the slide plate 1, degree of tightness according to chain, by turn adjusting screw rod 3, in screw thread is progressive, drive chain transmission mounted thereto 4 and slide,, produce the purpose of regulating the chain degree of tightness apart from just reaching so chain transmission 4 slides because on the chain transmission 4 chain is installed, after regulating degree of tightness, bolt 7 is tightened.After tricycle uses a period of time, the chain pine, can looser a bolt 7 earlier, turn adjusting screw rod 3 is adjusted chain.
The utility model is simple in structure, and is easy to use, low cost of manufacture, and the degree of tightness that can regulate chain easily, the precision height reduces chain wear, reduces the motor resistance, increases the service life, and has saved material simultaneously.
