Abstract
The utility model discloses a kind of crowbar assembly, comprise crowbar body and as the bearing of crowbar body fulcrum, described crowbar body front end is provided with bearing pin, bearing pin middle part is fixedly connected with crowbar body front end, described bearing comprises base plate, is fixed on the channel-section steel body on base plate, the trend of channel-section steel body groove is vertical with base plate, the cell wall of channel-section steel body is provided with three pairs of support slots that highly do not wait, every pair of support slot is located on two cell walls of channel-section steel body relatively, and every pair of support slot is used for the two ends of rotational support bearing pin when crowbar body front end inserts channel-section steel body groove.
Description
Technical field
The utility model relates to a kind of crowbar assembly.
Background technology
Cut before film, need will be fixed on large volume film on unreeling shaft and be installed to the end that unreels of cutting machine, under the condition without weight-lifting equipment, operating personal can only be used crowbar to rely on manpower unreeling shaft two ends to be raised to respectively to the end that unreels of cutting machine, because the large radial dimension of rolling up film often changes, make the height of crowbar fulcrum need often to adjust, operating personal is usually used fragment of brick as cushion block, by increasing or reduce the quantity of fragment of brick, regulate the height of fulcrum, so both inconvenient, also dangerous.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of fulcrum height selectable crowbar assembly.
The utility model solves the technical scheme that its technical matters adopts: a kind of crowbar assembly, comprise crowbar body and as the bearing of crowbar body fulcrum, described crowbar body front end is provided with bearing pin, bearing pin middle part is fixedly connected with crowbar body front end, described bearing comprises base plate, be fixed on the channel-section steel body on base plate, the trend of channel-section steel body groove is vertical with base plate, the cell wall of channel-section steel body is provided with three pairs of support slots that highly do not wait, every pair of support slot is located on two cell walls of channel-section steel body relatively, every pair of support slot is used for the two ends of rotational support bearing pin when crowbar body front end inserts channel-section steel body groove.
The beneficial effects of the utility model are: the utility model is simple in structure, practical, and the height of fulcrum has third gear to select, and all around mobile support saddle is to regulate the position of fulcrum.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
In figure: 1. crowbar body; 2. bearing pin; 3. base plate; 4. channel-section steel body; 5. support slot; 6. roll up greatly film; 7. unreeling shaft.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
A kind of crowbar assembly as shown in Figure 1, 2, comprise crowbar body 1 and as the bearing of crowbar body 1 fulcrum, described crowbar body 1 front end is provided with bearing pin 2, bearing pin 2 middle parts are fixedly connected with crowbar body 1 front end, described bearing comprises base plate 3, is fixed on the channel-section steel body 4 on base plate 3, the trend of channel-section steel body 4 grooves is vertical with base plate 3, the cell wall of channel-section steel body 4 is provided with three pairs of support slots 5 that highly do not wait, the every pair of support slot 5 is located on two cell walls of channel-section steel body 4 relatively, and the every pair of support slot 5 is for the two ends of rotational support bearing pin 2 when crowbar body 1 front end insertion channel-section steel body 4 groove.
During use, according to the radial dimension of large volume film 6, first determine that unreeling shaft 7 is to the suitable distance of channel-section steel body 4, then crowbar body 1 front end is passed the groove that inserts channel-section steel body 4 from unreeling shaft 7 belows, one end, select again the support slot 5 of a pair of identical height, then bearing pin 2 two ends are shelved on respectively to this in support slot 5, firmly crowbar body 1 rear end is lifted again, crowbar body 1 can be raised to unreeling shaft 7 one end of crowbar body 1 top the end that unreels of cutting machine around bearing pin 2 center rotating time, adopt and use the same method, unreeling shaft 7 other ends can be raised to the end that unreels of cutting machine.
Above-mentioned embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
