Abstract
The utility model discloses an anti-drop-out device for a clamping tool. The anti-drop-out device comprises an anti-drop-out bolt and a limit plate, wherein one end, which is provided with threads, of the anti-drop-out bolt is smaller than the other end of the anti-drop-out bolt; a screw of which the diameter is greater than that of the bolt is positioned near one end which is provided with the threads in the middle of the anti-drop-out bolt, and a polished rod of which the diameter is smaller than that of the screw is positioned near the other end; the diameter of the large end of the anti-drop-out bolt is greater than that of the screw; a screw hole which is matched with the screw on the anti-drop-out bolt is formed in the limit plate; and the anti-drop-out bolt penetrates through the limit plate by threads. In a production workshop of manufacturing industry, a mode of screwing by using the bolt is adopted to fulfill the aim of clamping; and in the using process, the bolt is separated from other parts of the clamping tool, and by the anti-drop-out device, the bolt can be integrated on the clamping tool to avoid the trouble of taking and putting the bolt. The anti-drop-out device is safe and reliable, simple in structure and convenient to install, the efficiency of clamping parts by workers can be improved, and the action steps of staff can be reduced.
Description
Technical field
The utility model relates to the anti-device that drops out of using in a kind of mounting shop, particularly a kind of anti-device that drops out of clamping tool.
Background technique
In the manufacturing industry manufacturing shop, often need to use the mode of bolt tightening to reach the purpose of clamping, in application process, bolt is that other parts with clamping tool are what to be separated, like this, the employee needs back and forth taking and placing bolt in operating process, so not only increase employee's additional move, and affects the efficient of production line.For reducing the action waste in employee's clamping process, safe and reliable clamping tool is anti-to drop out device in the urgent need to designing and producing, and enhances productivity, and reduces employee's action step.
Summary of the invention
The purpose of this utility model is to provide a kind of clamping tool the anti-device that drops out, the anti-bolt that drops out, a described anti-threaded end that drops out bolt is less than the other end, there is one section screw rod that diameter is larger than the diameter of bolt the described anti-bolt centre that drops out by a threaded end, and one section less than screw diameter polished rod is arranged by the other end, and the described anti-diameter at butt end that drops out bolt is larger than screw diameter; A limiting board has on the described limiting board and anti-drops out the screw that screw rod is complementary on the bolt, and the described anti-bolt that drops out is to prevent dropping out device by the clamping tool of screw thread cross-under with limiting board.
Technical solution of the present utility model is such: a kind of clamping tool is anti-to drop out device, comprises anti-ly dropping out bolt, limiting board, it is characterized in that anti-ly dropping out bolt and limiting board is by the screw thread cross-under.
An anti-threaded end that drops out bolt is less than the other end.
Anti-have one section screw rod that diameter is larger than the diameter of bolt by a threaded end in the middle of dropping out bolt, and by the other end one section less than screw diameter polished rod is arranged, and the described diameter at butt end of preventing dropping out bolt is larger than screw diameter.
Have on the limiting board and anti-drop out the screw that screw rod is complementary on the bolt.
The utility model has the advantages that: in the manufacturing industry manufacturing shop, often need to use the mode of bolt tightening to reach the purpose of clamping, in application process, bolt is that other parts with clamping tool are what to be separated, by using the anti-device that drops out of above-mentioned clamping tool, bolt can be incorporated on the clamping tool, eliminate the action waste of taking and placing bolt.The utility model is that a kind of safe and reliable clamping tool is prevented dropping out device, and it is simple in structure, is convenient to install, and can improve the efficient of workman's clamping parts, reduces employee's action step.
Description of drawings
It is such that structure of the present utility model consists of:
Fig. 1 is the anti-application example schematic diagram that drops out device of the utility model clamping tool;
Fig. 2 is the anti-anti-structural representation that drops out bolt of device that drops out of the utility model clamping tool;
Among Fig. 1～Fig. 2, anti-bolt (1), limiting board (2), the anchor clamps positioning plate (3) of dropping out.
Embodiment
For further setting forth 26S Proteasome Structure and Function of the present utility model, below in conjunction with accompanying drawing the utility model is elaborated, but be to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.With reference to accompanying drawing:
The anti-device that drops out of clamping tool described in the utility model, as shown in Figure 1, comprise an anti-bolt (1) that drops out, an anti-threaded end that drops out bolt (1) is less than the other end, by a threaded end one section screw rod that diameter is larger than the diameter of bolt is arranged in the middle of preventing dropping out bolt (1), and one section less than screw diameter polished rod is arranged by the other end, and the described anti-diameter at butt end that drops out bolt (1) is larger than screw diameter; A limiting board (2), limiting board (2) passes through the screw thread cross-under with the anti-bolt (1) that drops out; Have on the described limiting board (2) and anti-drop out the screw that the upper screw rod of bolt (1) is complementary.Use when described clamping tool is anti-to drop out device, first limiting board (2) is installed to the outside of anchor clamps positioning plate (3), during installation, should make tapped hole center line on the limiting board (2) and the central lines of the through hole on the anchor clamps positioning plate (3); Then, will prevent dropping out bolt (1) and be screwed in the tapped hole of limiting board (2), the bolt microcephaly will be passed through hole on the anchor clamps positioning plate (3), and be screwed in the screw on the part and can play clamping action; At this moment, prevent that dropping out bolt can be free to slide in the tapped hole of limiting board (2), but can not drop out.
Above disclosed only be the more excellent specific embodiment of the utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
Claims (4)
