Description
Technical field
The utility model relates to mechanical field, particularly a kind of bayonet joint sheet.
Background technology
Crane span structure is often used in the middle of our life, and crane span structure in cable transmission than indispensable, and due to the limited length of single crane span structure, so linking together and reach the length of needs again may be needed because of the problem of length when in use, this time, we will use brace, that employing 12 screws are fixed crane span structure junction in the design of original crane span structure brace, but because site operation personnel technology and environment all have a great impact in this original interconnection technique mode, crane span structure and crane span structure junction is caused to be installed slowly, in conjunction with the feature of the construction of construction and installation electrical engineering, present urgent need one is improved to brace original brace and is improved, thus improve the efficiency of producing and installing.
Utility model content
For the deficiencies in the prior art, the utility model aims to provide a kind of bayonet joint sheet, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme:
A kind of bayonet joint sheet, described brace is made up of hard stainless steel, described brace is identical with the shape of crane span structure and in the same size, described brace is divided into internal layer with outer, described internal layer is connected and fixed in bottom with outer, described internal layer is identical with the thickness of described crane span structure with the width of outer interlayer, be provided with one in the top center portion position of described bayonet joint sheet and fasteningly turn bolt, the described bolt that turns is made up of bolt head and hitching post, described bolt head is set to regular hexagon wrench shape, described hitching post is provided with external screw thread, described bayonet joint sheet internal layer and outer top be all provided with size identical turn keyhole, the described keyhole internal layer that turns is provided with internal thread.
Preferably, the internal layer upper side of described brace and outer downside are rubbing surface, and described rubbing surface is provided with friction groove.
Preferably, described brace is processed by waste-material-preparing.
Preferably, described brace internal layer becomes " V " shape with skin at opening part.
Beneficial effect: a kind of bayonet joint sheet adopting this invention to provide, the supporting screw of outsourcing is not needed when two crane span structures need to connect, do not need to carry out punching to crane span structure, direct employing is direct insertion carries out socket joint, then the fastening bolt that turns being located at brace top is carried out fastening to ectonexine, shirtsleeve operation completes whole connection, speed of application is fast, quality is high, when needs are finely tuned length, oneself can select the degree of depth inserting brace, construction is made to become more flexible, and also all being processed by waste-material-preparing of material of the brace adopted, environmental protection is attractive in appearance, it also avoid the generation of crane span structure for the crane span structure depending condition produced in large-sized cable threading process simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of described bayonet joint sheet;
Fig. 3 is the described fastening partial schematic diagram turning bolt;
Fig. 4 is described rubbing surface schematic diagram;
Description of reference numerals: 1-brace, 2-crane span structure, 3-internal layer, 4-is outer, and 5-is fastening turns bolt, 6-bolt head, 7-hitching post, 8-external screw thread, and 9-turns keyhole, 10-friction groove.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of bayonet joint sheet 1, described brace 1 is made up of hard stainless steel, described brace 1 is identical with the shape of crane span structure 2 and in the same size, described brace 1 is divided into internal layer 3 and outer 4, described internal layer 3 is connected and fixed in bottom with outer 4, width between described internal layer 3 with outer 4 is identical with the thickness of described crane span structure, be provided with one in the top center portion position of described bayonet joint sheet 1 and fasteningly turn bolt 5, the described bolt 5 that turns is made up of bolt head 6 and hitching post 7, described bolt head 6 is set to regular hexagon wrench shape, described hitching post is provided with external screw thread, described bayonet joint sheet 1 internal layer 3 and outer 4 tops be all provided with size identical turn keyhole 9, the described keyhole internal layer that turns is provided with internal thread, because common brace when in use process is loaded down with trivial details, efficiency of construction is low, in the present embodiment, the supporting screw of outsourcing is not needed when two crane span structures need to connect, do not need to carry out punching to crane span structure yet, direct employing is direct insertion carries out socket joint,
Because the two ends of brace 1 are all used to fixing crane span structure, when two crane span structures are inserted into inside brace 1 respectively, re-use the fastening bolt 5 pairs of internal layers 3 and outer 4 that turn and carry out fastening.
It should be noted that inside existing technology, brace is fixing for the connecting length of crane span structure, when in the process used, without any fine setting scope, and in the present embodiment, what we can control is the length that crane span structure 2 inserts brace 1.So also just well solve the problem of fine setting.
In addition, as shown in Figure 4, internal layer 3 upper side of described brace 1 and outer 4 downsides are provided with friction groove 10 for rubbing surface described in rubbing surface, described brace internal layer 3 becomes " V " shape with outer 4 at opening part, after connection completes, in order to ensure that the connectivity robustness between brace 1 and crane span structure 2 just should increase the friction of contact-making surface, and groove 10 is exactly to increase friction, increase the firm degree connected, and the opening of " V " shape is in order to crane span structure 2 better enters at the beginning.
Described on base, described brace 1 is processed by waste-material-preparing, so both solves the process problem of waste material, and environmental protection, saves, reduces the disbursement of construction, add operating efficiency.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; the some distortion that can also make and improvement, these all belong to protection range of the present utility model.
