Abstract

The utility model relates to a contrary device field, in particular to contrary device that ends of conveyer of ending. Mainly constitute by fixeing jacket, contrary dog, spring assembly, star gear, keyway, fixed orifices, shaft hole, tooth's socket, fixeing jacket's outside processing have a fixed orifices, fixeing jacket's inboard processing has a tooth's socket, the star gear install the inboard at fixeing jacket, the star gear circumference outside install contrary dog, the star gear install spring assembly with contrary dog middle part, the central point of star gear put processing and have the shaft hole, the lateral wall in shaft hole on processing have the keyway. Beneficial effect: simple structure, maneuverability is stronger, and application scope is wide, adopts the cooperation of contrary dog and tooth's socket, has solved the contrary problem that the device availability factor is low of ending, reduces it and destroys probability and input cost.

Description

A kind of conveyer non-return device

Technical field

This utility model relates to non-return device field, particularly to a kind of conveyer non-return device.

Background technology

At present, when carrying out incline direction transport due to conveyer, once take a turn for the worse, then the accident generation etc. that can not estimate can be brought.So, the type of domestic and international conveyer non-return device is varied, studies a lot of, but yet suffers from problems, processing technology such as non-return device is loaded down with trivial details, and operation logic is complicated, and service life is shorter, need often to change, add use cost, and use check effect not to be effectively ensured.As can be seen here, prior art needs further improvement and develops.

Utility model content

This utility model provides a kind of conveyer non-return device for solving the defect in above-mentioned prior art and economic benefit, to improve non-return device service efficiency, reduces it and damages probability and input cost, and its technical scheme adopted is as follows.

A kind of conveyer non-return device, it is characterized in that: include fixed jacket, check block, spring assembly, star-wheel, keyway, fixing hole, axis hole, teeth groove, the outside processing of described fixed jacket has fixing hole, the inner side processing of fixed jacket has teeth groove, described star-wheel is arranged on the inner side of fixed jacket, described star-wheel periphery is provided with check block, described star-wheel and check block middle part are provided with spring assembly, the center processing of described star-wheel has axis hole, and on the sidewall of described axis hole, processing has keyway.

Above-mentioned check block is arranged in teeth groove, and when conveyer takes a turn for the worse, check block can be bumped in teeth groove at short notice, thus stoping it to take a turn for the worse.

This utility model has the advantage that simple in construction, and operability is relatively strong, applied widely, adopts the cooperation of check block and teeth groove, solves the problem that non-return device service efficiency is low, reduces it and damages probability and input cost.

Accompanying drawing explanation

Fig. 1: overall structure schematic diagram of the present utility model.

Symbol description: 1. fixed jacket, 2. check block, 3. spring assembly, 4. star-wheel, 5. keyway, 6. fixing hole, 7. axis hole, 8. teeth groove.

Detailed description of the invention

Below in conjunction with accompanying drawing and example, this utility model patent is described further.

As shown in Figure 1, a kind of conveyer non-return device of the present utility model, including fixed jacket 1, check block 2, spring assembly 3, star-wheel 4, keyway 5, fixing hole 6, axis hole 7, teeth groove 8, the outside processing of described fixed jacket 1 has fixing hole 6, the inner side processing of fixed jacket 1 has teeth groove 8, described star-wheel 4 is arranged on the inner side of fixed jacket 1, described star-wheel 4 periphery is provided with check block 2, described star-wheel 4 is provided with spring assembly 3 with check block 2 middle part, the center processing of described star-wheel 4 has axis hole 7, on the sidewall of described axis hole 7, processing has keyway 5.

Preferred check block 2 is arranged in teeth groove 8.

When conveyer takes a turn for the worse, conveyer can drive star-wheel 4 to reverse, and then check block 2 can move towards teeth groove 8, and teeth groove 8 can stop the motion of check block 2, and the reverse of star-wheel 4 is obstructed, thus stoping the reverse of conveyer.
