Abstract
The utility model discloses a bevel gear driven type machinery jack, including base, casing, lifting sleeve, top pad, nut, screw rod, big bevel gear, little bevel gear, thrust ball bearing, the screw rod lower extreme passes through key no. 3 with big bevel gear to be connected, and big bevel gear sets up in the base just and thrust ball bearing interference fit, and its special part lies in: this jack is still including axle, ratchet, pawl and gearing cover, and the one end of axle is passed through key no. 2 and is connected with little bevel gear, and the other end passes through key no. 1 to be connected with the ratchet, and the pawl passes through the spring to be fixed in the ratchet cover, little bevel gear and bevel gear constitution gear drive greatly, ratchet and the one -way intermittent movement mechanism of pawl constitution. The utility model discloses owing to increased ratchet pawl module newly, when the jack was in the weight lifting state, the pawl compressed tightly the ratchet under the effect of spring force, prevent the ratchet antiport, realizes one -way spacingly. If quick return, only need with the pawl mention can, consequently, avoided the maloperation, improved security and reliability.
Description
Technical field
This utility model belongs to technical field of mechanical transmission, is specifically related to a kind of Bevel Gear Transmission formula mechanic jacks.
Background technology
Jack is lifting, the reinforcement instrument commonly used in daily life and rescue.The structure of existing Bevel Gear Transmission formula mechanic jacks mainly includes the casing above handle, hypanthium, screw rod and base and base.Casing is provided with cap assembly, and screw rod is provided with bevel gear wheel, and bevel gear wheel engages with the bevel pinion being arranged on small coning gear shaft system left end, and one end of small coning gear shaft system is provided with handle, is provided with sliding guide rail in base, and screw rod bottom is provided with slide block.Compared with traditional screw jack, existing Bevel Gear Transmission formula mechanic jacks rapid operation, convenience, and center of gravity does not moves up and down with screw rod during operation, stability under loading is uniform, but due to rely solely on trapezoidal thread can self-locking inherent character support weight, still without bigger improvement in terms of safety, reliability.
Utility model content
Technical problem to be solved in the utility model is to provide one, and safety is good, reliability is high, easy to operate, the Bevel Gear Transmission formula mechanic jacks of labour-saving band click structure.
For solving above-mentioned technical problem, the Bevel Gear Transmission formula mechanic jacks technical scheme of present invention design is:
nullA kind of Bevel Gear Transmission formula mechanic jacks，Including base、The housing being arranged on base、The jacking sleeve being slidably connected with housing、The top pad threadeded with jacking sleeve、It is fixed on the nut of jacking sleeve lower end、The screw rod that self-locking thread is connected is used with nut、Bevel gear wheel、Bevel pinion、Thrust ball bearing，Described screw rod upper end is provided with back-up ring two and hex bolts two，Lower end is connected by key three with bevel gear wheel，Described bevel gear wheel be arranged in base and with thrust ball bearing interference fit，This jack also includes axle、Ratchet、Pawl-and-gearing cover，One end of described axle is provided with back-up ring one and hex bolts one and this axle head and is connected with bevel pinion by key two，The other end is connected with ratchet by key one，Described ratchet is fixed in ratchet casing by spring，Described bevel pinion forms gear drive with bevel gear wheel，Described ratchet forms one-way intermittent motion mechanism with ratchet.
It is compared to existing Bevel Gear Transmission formula mechanic jacks, this utility model is owing to having increased click module newly, during use, handle is mounted on an axle, and itself and ratchet and bevel pinion are connected as a single entity by keyway arrangements by axle, when jack is in weight lifting state, (B to) turning handle clockwise, ratchet compresses ratchet under spring force, prevents ratchet from rotating backward, it is achieved than threading unidirectional spacing of jack.If wanting returning quickly, it is only necessary to mentioned by ratchet, this mode avoids maloperation the most greatly.Therefore, the Bevel Gear Transmission formula mechanic jacks after newly-increased click structure greatly improves the safety and reliability of mechanic jacks.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of band click Bevel Gear Transmission formula mechanic jacks of the present utility model.
Wherein: 1 be base, 2 be thrust ball bearing, 3 be ratchet, 4 be axle, 5 be ratchet for key one, 6 for back-up ring one, 7,8 be spring, 9 be ratchet casing, 10 be pawl bar, 11 be bevel pinion for key two, 12 for hex bolts one, 13,14 be top pad for back-up ring two, 15 for hex bolts two, 16,17 be jacking sleeve, 18 be screw rod, 19 be housing, 20 be nut, 21 be bevel gear wheel, 22 be key three.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1, Bevel Gear Transmission formula mechanic jacks of the present utility model includes: base 1, the housing 19 being arranged on base 1, with housing 19 by the jacking sleeve 17 that is slidably connected (in this detailed description of the invention, formed be slidably connected by arranging slide rail and slide block between housing 19 and jacking sleeve 17), the top pad 16 being threaded connection with jacking sleeve 17, the nut 20 of jacking sleeve 17 lower end it is fixed on by trip bolt, the screw rod 18 that self-locking thread is connected is used with nut 20, and it is arranged on back-up ring 2 14 and the hex bolts 2 15 that screw rod 18 end face moves axially for limiting nut 20, bevel gear wheel 21, bevel pinion 13, thrust ball bearing 2, axle 4, ratchet 3, ratchet 7, ratchet casing 9.Described screw rod 18 lower end is connected by key 3 22 with bevel gear wheel 21, load in base 1 after described bevel gear wheel 21 and thrust ball bearing 2 interference fit, one end of described axle 4 and bevel pinion 13 is connected by key 2 11 and this axle head is provided with back-up ring 1 and hex bolts 1, bevel pinion 13 and bevel gear wheel 21 are by gear drive power, the other end of axle 4 is connected with ratchet 3 by key 1, described ratchet 7 is fixed in ratchet casing 9 by spring 8, and ratchet 3 and ratchet 7 form one-way intermittent motion mechanism.
nullWhen jack needs weight lifting，From C to rotating clockwise axle 4，The power applied is by axle 4、Bevel pinion 13、Bevel gear wheel 21 transmits，Screw rod 18 (B to) clockwise is rotated，I.e. screw rod 18 has the trend rotated down，But between nut 20 and housing 19, it is designed with structure (the top pad 16 forbidden nut 20 and rotate、Jacking sleeve 17 and nut 20 are connected as a single entity by the way of screw thread with trip bolt，And between jacking sleeve 17 and housing 19, it is designed with slide block and rail structure，So just define the structure that nut 20 cannot rotate)，Finally make screw rod 18 can only realize rotating clockwise (B to) and cannot realize moving downward，Nut 20 can only realize axially rising and cannot rotating，And due to top pad 16、Jacking sleeve 17 and nut 20 are integrated，The ascending motion the most without spin of nut 20 makes also to be able to realize rising without spin by weight lifting goods.When jack needs return, only need to be mentioned by ratchet 7 and then turn to, such ratchet 3 just can rotate backward, and jack will decline automatically because of pressurized, and such ratchet 3 and ratchet 7 structure are achieved that the function of unidirectional self-lock and returning quickly.
