Abstract
The utility model relates to a device for connecting a lever block spanner with a ratchet casing, which comprises a ratchet casing on a lever block body, and a spanner inner plate which is arranged on the spanner and is in contact with the ratchet casing, wherein the outer side of the spanner inner plate is provided with a reinforcing plate adjacent to the ratchet casing. The lower part of the reinforcing plate is provided with a wear ring arranged in a clamp sleeve, and the wear ring is mutually contacted with the clamp sleeve which is sheathed with the lower part of the ratchet casing. The utility model belongs to the improvement of the prior art, the strength and the stiffness of the spanner can be improved, and the connection wear between the spanner and the ratchet casing can be improved. The utility model has the advantages of simple structure, available structure and low cost.
Description
Technical field
The utility model relates to a kind of improvement, belong to the product structure of Lever Blocks connection structure between existing Lever Blocks spanner and the ratchet case.
Background technology
In engineering goods, the cucurbit product belongs to comparatively ripe product, mainly includes kinds such as chain block and Lever Blocks, and as disclose a kind of Lever Blocks utility model patent on the Chinese patent communique, the patent No. is ZL03230717.9.In traditional Lever Blocks structure, spanner inner panel and ratchet case adopt the connection structure that directly fastens to see shown in the accompanying drawing 2, wherein exist the friction face 3 that is in contact with one another between spanner inner panel 1 and the sour jujube opinion case 2; Because in use, pinch bar is reciprocating, make the connecting portion between spanner inner panel and the ratchet case directly produce friction, and because of the material of above-mentioned two kinds of parts is similar to, period of service one is long, just very quick-wearing lost efficacy, thereby had increased use cost the service life of reducing whole Lever Blocks product.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of can the improvement between spanner and the ratchet case to be connected worn-down Lever Blocks spanner and ratchet case connecting device, it comprises on the Lever Blocks body on the ratchet case and spanner and the contacted spanner inner panel of ratchet case, in the arranged outside of spanner inner panel the brace panel adjacent with the ratchet case is arranged.
Described brace panel is fixed on the outside of spanner inner panel, and the bottom of brace panel is provided with one by being put in the flow ring in the cutting ferrule and being in contact with one another, and described cutting ferrule then is socketed in the bottom of ratchet case.
The utility model belongs to a kind of improvement to prior art, and it can improve the strength and stiffness of spanner, improves between spanner and the ratchet case to be connected wearing and tearing, have simple for structure, low cost of manufacture, characteristics such as effect is remarkable.
Description of drawings
Fig. 1 is the integral structure scheme drawing of Lever Blocks.
Fig. 2 is existing Lever Blocks spanner and ratchet case connection structure scheme drawing.
Fig. 3 is the utility model Lever Blocks spanner and ratchet case connection structure scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, Lever Blocks mainly is made up of cucurbit body 4, sprocket wheel 5, spanner 6 etc.Shown in Figure 3, on the Lever Blocks body 4 described in the utility model ratchet case 2 is arranged, with ratchet case 2 contacted spanner inner panels 1, the brace panel 7 adjacent with ratchet case 2 arranged on the spanner 6 in the arranged outside of spanner inner panel 1.Described brace panel 7 is to be fixed on the outside of spanner inner panel 1, and the bottom of brace panel 7 is provided with one and is placed in the flow ring 9 in the cutting ferrule 8 and is in contact with one another 8 bottoms that are socketed in ratchet case 2 of described cutting ferrule.The utility model has played the effect of bearing owing to increased a flow ring 9 made from antifriction material; Increased a brace panel that hardness is higher, and be fixed on the spanner inner panel and move with spanner, it has improved the spanner strength and stiffness, has improved friction condition; Above-mentioned connection structure has been blocked the direct contact between spanner inner panel and the ratchet case, change into by carrying out radial friction between antifriction material and the brace panel, brace panel and the ratchet case higher with hardness carry out planar friction, it not only rotates flexibly than original technology, and after back and forth testing for 160,000 times under the same conditions, no any unusual, carry out dissembling inspection friction position and have only the trace wearing and tearing.
Claims (2)
1, a kind of Lever Blocks spanner and ratchet case connecting device, it comprises on the Lever Blocks body on the ratchet case and spanner and the contacted spanner inner panel of ratchet case, it is characterized in that in the arranged outside of spanner inner panel (1) brace panel (7) adjacent with ratchet case (2) being arranged.
2, Lever Blocks spanner according to claim 1 and ratchet case connecting device, it is characterized in that described brace panel (7) is fixed on the outside of spanner inner panel (1), the bottom of brace panel (7) is provided with one and is placed in the flow ring (9) in the cutting ferrule (8) and is in contact with one another, and described cutting ferrule (8) then is socketed in the bottom of ratchet case (2).
