Abstract
A crowbar capable of adjusting a fulcrum comprises a bracket 1; supporting plates at two sides of the bracket 1 are provided with an opening 2 respectively; one side of the internal side of the opening 2 is provided with a tooth space 3; the openings 2 at two sides are internally provided with a fixed mechanism 4 that is matched with the openings 2; the fixed mechanism 4 is provided with a swinging ratchet 7; a lever sleeve 5 is connected with the shafts of the fixed mechanism 4 arranged at two sides; the crowbar 6 is internally sheathed by the lever sleeve 5; and when the height of the fulcrum needs to be adjusted, the crowbar 6 can be removed, two ends of the combination of the fixed mechanism 4 and the lever sleeve 5 are lifted up respectively, the ratchet 7 is poked to the outside part of the tooth space 3 and moves up and down to a suitable position, and the ratchet 7 is loosened and enters the tooth space 3. The crowbar has the advantages of simple structure and convenient usage.
Description
Technical field
The utility model relates to a kind of crowbar, the adjustable crowbar of particularly a kind of fulcrum.
Background technology
The crowbar of people's use generally is a steel rod, usually to look for a suitable fulcrum in use, however limited under a lot of situation owing to field condition, usually be difficult for finding a suitable fulcrum, usually use replacements such as fragment of brick, stone, be difficult to meet the demands.Especially under some deadly conditions as in earthquake, the typhoon rescue later or in the armament guarantee in Gobi desert, desert, engineering first-aid repair, can not find suitable crowbar fulcrum and not only can lose time but also may cause unnecessary property or human loss.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of fulcrum adjustable crowbar, and the height of crowbar fulcrum can be regulated in classification, can raise or reduce the height of fulcrum in use as required.
In order to achieve the above object, the technical solution of the utility model is achieved in that the adjustable crowbar of a kind of fulcrum, comprise support 1, all have opening 2 on the supported on both sides plate of support 1, the inboard teeth groove 3 that is provided with on one side of opening 2, in the opening 2 of both sides suitable with it fixed mechanism 4 is arranged, lever cover 5 is connected with 4 of the fixed mechanisms of both sides, and lever overlaps in 5 and is socketed with crowbar 6.
Described fixed mechanism 4 is provided with the ratchet that can swing 7.
Because the utility model is provided with teeth groove 3 and ratchet 7, so adjustable height.The utlity model has characteristics simple in structure, easy to use.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is that fixed mechanism 4 and lever overlap 5 assembly drawing.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are described in detail.
With reference to Fig. 1, Fig. 2, the adjustable crowbar of a kind of fulcrum, comprise support 1, all have opening 2 on the supported on both sides plate of support 1, the inboard of opening 2 is provided with teeth groove 3 on one side, in the opening 2 of both sides suitable with it fixed mechanism 4 arranged, and fixed mechanism 4 is provided with the ratchet 7 of a swing, lever cover 5 is connected with 4 of the fixed mechanisms of both sides, and lever overlaps in 5 and is socketed with crowbar 6.
Principle of work of the present utility model is: an end of pressing crowbar 6 during use, lever cover 5 will rotate around fixed mechanism 4, in the teeth groove 3 that mates with ratchet 7 on the ratchet 7 insertion support 1 tightly on the fixed mechanism 4, this moment, whole fixed mechanism 4 just tightened fixedly bear external force at this moment.When needs are regulated the fulcrum height, only need take out crowbar 6, promote the two ends of the combination of fixed mechanism 4 and lever cover 5 then respectively, and with 7 groups of ratchets to teeth groove 3 outsides, move up and down the combination of fixed mechanism 4 and lever cover 5, when having arrived correct position, unclamp ratchet 7 again and make its teeth groove that enters other sustained height 3 can finish adjustment.
Claims (2)
1. adjustable crowbar of fulcrum, comprise support (1), it is characterized in that, all have opening (2) on the supported on both sides plate of support (1), the inboard teeth groove (3) that is provided with on one side of opening (2), suitable with it fixed mechanism (4) is arranged in the opening of both sides (2), and lever cover (5) is connected with fixed mechanism (4) axle of both sides, is socketed with crowbar (6) in the lever cover (5).
2. the adjustable crowbar of a kind of fulcrum according to claim 1 is characterized in that described fixed mechanism (4) is provided with the ratchet that can swing (7).
