Detailed description of the invention
The technological means realized to make this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth this utility model further.
See shown in Fig. 1 to Fig. 3, the utility model discloses the non-return structure in the assembling of a kind of operating theater instruments, the anterior operating side 200 comprising rear handle 100 and be connected with rear handle, rear handle is used for holding for operator, in use, often there will be skidding between palm and rear handle, not only reduce work efficiency like this, also improve danger during operation; In order to increase the frictional force between palm and rear handle, this utility model is provided with Anti-slip cover or rag or granule (not shown in FIG.) on the outer surface of rear handle, Anti-slip cover can be coated in whole rear handle, also can locally arrange, it can be decided according to the actual requirements, material for Anti-slip cover does not limit herein, as long as it can play anti-skidding acting on.
This utility model rear handle 100 is the cylindrical structure of one end open and inner hollow, the medial surface of rear handle is provided with draw-in groove 120, draw-in groove 120 can be one, also can for being symmetricly set on two on the medial surface of rear handle up and down, can certainly be two of asymmetric setting, one circle can also be set for the circumferencial direction along rear handle medial surface; In order to coordinate with draw-in groove, what this utility model was corresponding is provided with wedge shape fixture block 210 in the upper and lower side of anterior operating side 200, wedge shape fixture block 210 can be one, also it can be symmetrical two, can certainly be two of asymmetric setting, can also for arrange a circle along anterior operating side excircle length direction; The height of wedge shape fixture block 210 is identical with the height of draw-in groove 120; Wedge shape fixture block 210 can be one-body molded on anterior operating side, and dismountable mode also can be adopted to be fixed on anterior operating side; When draw-in groove be up and down symmetrically arranged two time, wedge shape fixture block is also symmetrically arranged two pieces up and down; When draw-in groove is that when arranging a circle along the circumferential length direction of rear handle medial surface, wedge shape fixture block is for arrange a circle along anterior operating side excircle length direction.
Distance H between the upper surface of the fixture block of wedge shape up and down of the anterior operating side 200 of this utility model, slightly larger than the diameter L of rear handle opening, makes to be interference fit between the upper surface of the fixture block of wedge shape up and down of anterior operating side when installing and the medial surface of rear handle; During assembling, first the opening of anterior operating side from rear handle is inserted, now, wedge shape fixture block 210 is inclined-plane 211 towards the one side of rear handle opening, inclined-plane is convenient to anterior operating side and is entered into rear handle inside, the one side of wedge shape fixture block rear handle opening is dorsad plane 212, and this plane finally can flush with the side of draw-in groove; Thickness H due to anterior operating side is greater than rear handle opening diameter L, it needs firmly to insert, until when wedge shape fixture block slides in draw-in groove, just stop the thrust to anterior operating side, wedge shape fixture block 210 is now fastened in draw-in groove 120 firmly, anterior operating side and rear handle are locked together, and this utility model once-through operation can complete assembling.
In order to improve the convenience of assembling, this utility model is provided with the notch 220 be opened on side, anterior operating side around wedge shape fixture block, wedge shape fixture block is positioned at notched areas, this utility model notch is U-type groove mouth, certainly, it also can be set to the notch of other shape according to actual needs, as long as the setting of this notch can slight anteriorly operating side axe movement when making wedge shape fixture block install, so that installation wedge shape fixture block; During installation, enter rear handle inside under the effect of wedge shape fixture block power outside, due to the existence of the extruding and notch that are subject to rear handle, wedge shape fixture block extrudes downwards, and wedge shape fixture block just can easily snap onto in draw-in groove.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
