Abstract
The utility model discloses a locking device, which comprises an imbedded body and a sleeve body, wherein the imbedded body comprises a column cap and a truncated cone shape rod body connected with the column cap, openings and a cylindrical hollow cavity communicated with the same are disposed on the sleeve body, the inner diameter of the hollow cavity is larger than the minimum outer diameter of the truncated cone shape rod body and smaller than the maximum outer diameter of the truncated cone shape rod body, the outer side diameters of the openings are larger than the inner side diameters of the openings, and the openings are arranged at the two ends of the sleeve body. When engaged with the matchable sleeve body, the imbedded body is provided with a truncated cone shape column which can be mutually fastened with the matchable sleeve body without any rotation, thereby greatly saving installation operation and improving working efficiency. In addition, the imbedded body and the sleeve body of the utility model are free of carving threads, thereby realizing convenient processing and low-cost manufacturing.
Description
[technical field]
The utility model relates to mechanical parts, relates in particular to a kind of locking device.
[background technique]
In mechanical assembly process, often need some locking devices that two separated components are fixed together, have the screw of screw thread and suitable nut and be exactly a kind of in the locking device.At present, the structure of screw and nut is generally: screw comprises breechblock and nut, and breechblock is generally the cylindrical metal body that is provided with screw thread, and breechblock is installed on the nut, can easily breechblock be screwed in the nut by nut, thereby will place the parts between nut and the nut to be fixed together.
But, in the structure of above-mentioned screw and nut, need rotary nut screw and nut could be fastened, operation is comparatively complicated, uses inconvenience, inefficiency.
[model utility content]
The purpose of this utility model provides a kind of locking device, and this locking device is simple to operate, easy to use, can reach the purpose of increasing work efficiency.
For achieving the above object, the utility model proposes following technological scheme:
A kind of locking device comprises embedded body and body; Described embedded body comprises the cap and the frustoconic shape body of rod that links to each other with described cap; Described body be provided with opening and with the cylindrical cavity of described open communication, described cavity internal diameter is greater than the minimum outer diameter of the described frustoconic shape body of rod, less than the maximum outside diameter of the described frustoconic shape body of rod.
Preferably, described open outer side diameter is greater than inside diameter.
Preferably, described opening is positioned at the two ends of described body.
Wherein, described embedded body and body are made by metal or plastics.
Preferably, described embedded body is made by stainless steel; Described body is made of copper.
Preferably, described cap is the regular polygon cylinder.
Preferably, be provided with screw thread in the described embedded body.
As can be seen from the above technical solutions, embedded body of the present utility model is provided with the frustoconic shape cylinder, and cooperating with suitable body can mutual fastening, need not rotate, and has saved fitting operation greatly, has improved working efficiency.In addition, embedded body of the present utility model and body need not be scribed screw thread, and be easy to process, and cost is low.
[description of drawings]
Fig. 1 is a structural drawing of the present utility model.
[embodiment]
Below in conjunction with specific embodiment and Figure of description the purpose of this utility model, technological scheme and advantage are described in detail.
Basic fundamental design of the present utility model is that employing taper cylinder replaces being provided with the cylindrical body of screw thread, when fixedly separated parts, only the taper cylinder need be pressed in the suitable body and get final product, and need not rotate, saved fitting operation greatly, reach the purpose of increasing work efficiency.
The utility model provides a kind of locking device, as shown in Figure 1, generally comprises embedded body 100 and body 200.
The frustoconic shape body of rod 104 that embedded body 100 comprises cap 102 and is mounted thereon; Embedded body 100 generally can be made by metal or rigid plastics.In more excellent embodiment, can adopt stainless steel material to make embedded body 100, to improve the hardness of embedded body 100, make insertion easier.
As further improvement of the utility model, the utility model improves opening 204, opening 204 is carried out design wide outside and narrow inside, and promptly the outside diameter of opening 204 is greater than inside diameter, so that the frustoconic shape body of rod of the embedded body 100 102 easier cavitys 202 that enter body 200.
Further, opening 204 can be arranged at the two ends of described body 200, and embedded body 100 can insert and clamp by any end from the two ends of body 200 like this, need not require great effort to differentiate and insert mouth, has further simplified operation, has improved working efficiency.
As further improvement of the utility model, the utility model improves cap 102, and described cap 102 is made as the regular polygon cylinder, makes the embedded body 100 easier persons of being operated use hand gripping, easy-to-operat.
As further improvement of the utility model, be provided with tapped hole in the embedded body 100, be connected with other parts to make things convenient for the utility model.
The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
