Abstract
The utility model discloses a gear-rack protective cover comprising a guide rail and a C-shaped rail which are both arranged on a movable frame body, wherein a cover and a retractable protective cover are arranged on the guide rail and the C-shaped rail; and the retractable protective cover is fixed at one end of the cover. The gear-rack protective cover disclosed by the utility model has the following advantage: in any state, the total distance between the retractable protective covers at the two ends is unchanged, thereby ensuring that the retractable protective covers always protect a rack when the rack moves along with the movable frame body. The gear-rack protective cover is simple in structure, rational in arrangement, simple in operation and low in manufacturing cost.
Description
Technical field
The utility model device belongs to mechanical equipment technical field, is a kind of rack-and-gear protective cover that is used for belt transporter.
Background technology
Along with improving constantly of science and technology development and industrial equipment level; The dustproof of belt transporter middle gear tooth bar is vital; There is complex structure in protective cover in the past, the shortcoming that manufacturing cost is high, and along with the difficult control of the mobile protective cover shift motion of tooth bar.
Summary of the invention
But the utility model purpose provide a kind of two ends move, flexible along with the tooth bar freedom of movement, rack-and-gear is played the rack-and-gear protective cover of protective action all the time, solve the complex structure that exists in the prior art, problem rambunctious not easy to operate.
The technical scheme that the utility model protective cover is adopted is, a kind of rack-and-gear protective cover is included in the guide rail and the C shape rail that are provided with on the removable support body, and guide rail and C shape rail are provided with cover and scalable protective cover, and scalable protective cover is fixed on cover one end.
The characteristic of the utility model also is,
Scalable protective cover is made up of 7 joints.
The two ends of scalable protective cover are provided with flange.
Scalable protective cover is provided with pulley, and pulley can slide on guide rail, C shape rail.
The beneficial effect of the utility model rack-and-gear protective cover is no matter be in the sort of state, total the distance of the scalable protective cover in two ends remains unchanged, to guarantee that scalable protective cover plays protective action all the time to tooth bar when tooth bar moves along with removable support body.Simple in structure, connection and reasonable arrangement, simple to operate, cost of manufacture is low.
Description of drawings
Fig. 1 is the structural representation of the utility model rack-and-gear protective cover.
Fig. 2 is the scheme drawing that is connected of scalable protective cover and guide rail, C shape rail in the utility model rack-and-gear protective cover.
Among the figure, 1. scalable protective cover, 2. cover, 3. guide rail, 4.C shape rail, 5. removable support body, 6. pulley, 7. flange.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The structure of the utility model rack-and-gear protective cover such as Fig. 1, shown in Figure 2; Be included in the guide rail 3 and C shape rail 4 that are provided with on the removable support body 5; Guide rail 3 is provided with cover 2 and scalable protective cover 1 with C shape rail 4; Scalable protective cover 1 is fixed on cover 2 one ends, and cover 2 plays the antisoiling effect of protection with the top that scalable protective cover 1 is arranged on rack-and-gear.Wherein, scalable protective cover 1 is the structure of 7 joints.The two ends of scalable protective cover 1 are provided with flange 7, and are as shown in Figure 1, close with the antisoiling gear parts cover handle of need.
Fig. 2 is the scheme drawing that is connected of scalable protective cover 1 and guide rail 3, C shape rail 4 in the utility model rack-and-gear protective cover, and Fig. 2 is the left view half-twist of Fig. 1.As shown in Figure 2, guide rail 3, C shape rail 4 is provided with two covers, is symmetrical set in twos, and the pulley 6 of scalable protective cover 1 slides on the C shape rail 4 at guide rail 3.
The working process of the utility model rack-and-gear protective cover is: cover 2 will play the protective action to rack-and-gear with scalable protective cover 1, and gear is motionless, and tooth bar is along with removable support body 5 moves.Cover 2 is fixed on the gear, the end of scalable protective cover 1 and guide rail 3, and C shape rail 4 is fixing.When track moved to the left, the scalable protective cover 1 in left side was in extended state, and the scalable protective cover 1 in right side is in compressive state, and is as shown in Figure 1.When track moved to the right, the scalable protective cover 1 in right side was in extended state, and the scalable protective cover 1 in left side is in compressive state.No matter be in the sort of state,, guarantee that when tooth bar moved along with removable support body 5,1 pair of tooth bar of scalable protective cover played protective action all the time total the distance of the scalable protective cover 1 in two ends remains unchanged.
