In manufacture of cement industry, need to use a large amount of machinery, all devices, requisite part is exactly bolt and securing means.In the maintenance process of equipment, often there will be bolt due to life time comparatively of a specified duration, by the problem of the corrosion-deformations such as cement powders, cause bolt to be often difficult to take out.In addition, when some plant maintenance, there will be the problem that cannot operate bolt by spatial constraints, such as, in some position, operator can only see wherein one of bolt, and this just requires at least to have two operator to carry out coordinating the operation such as fastening grade could implementing bolt; In addition, in the position that some space is less, cannot conventional tool be adopted to operate, greatly will increase work difficulty and the workload of attendant like this, and then cause maintenance time long, the normal problem of producing of impact.
Model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, easy to use and respond well easy holding down bolt.
Another object of the present utility model is to provide a kind of securing means using above-mentioned bolt.
Last technological scheme of the present utility model is achieved in that a kind of easily holding down bolt, and comprise interconnective nut and screw rod, wherein said screw rod free end is provided with boss, and the external diameter of boss is less than outer screw diameter, and boss is radially provided with positioning through hole.
In the easy holding down bolt of above-mentioned one, described boss is taper platform.
In the easy holding down bolt of above-mentioned one, described outer wall of boss is provided with some locating slots along screw axial.
After of the present utility model, a technological scheme is achieved in that a kind of securing means using easy holding down bolt described in the claims 3, wherein this securing means mainly comprises bolt, the screw rod of bolt has been threaded nut, protective housing is covered with at screw rod free end, protective housing sidewall is provided with the counterbore corresponding with locating slot, the internal thread through hole corresponding with locating slot is provided with at counterbore inner bottom part, be connected with fastening screw at internal thread through hole internal thread, protective housing to coordinate with locating slot by fastening screw that to be fixed on screw rod free end peripheral; Described nut is positioned at protective housing.
In above-mentioned securing means, described protective housing top exterior walls is spheric structure.
In above-mentioned securing means, be formed with packing space between described protective housing inwall and nut and screw rod, in packing space, be filled with the first refractory glue mud layer.
In above-mentioned securing means, protective housing inwall is distributed with some first location thorns.
In above-mentioned securing means, described protective housing outer wall is distributed with some second location thorns, protective housing outer wall is enclosed with the second refractory glue mud layer.
After the utility model adopts said structure, first existing screw rod free end one-body molded go out the external diameter boss less than screw rod, like this, when bolt not easily takes out, the instruments such as hammer can be adopted to knock boss makes bolt deviate from, like this, can avoid directly knocking screw rod causes thread distortion that bolt is scrapped.Secondly, boss arranges radial positioning through hole, this just make less position, some space or operator can only operating screw one end time, elongated element can be adopted to insert in positioning through hole, bolt is positioned, and then locking nut, simultaneously again in conjunction with the protective housing of nut periphery, form structure simply but very practical securing means.Protective housing outer wall is designed to spheric structure, namely can be used for the larger environment that weares and teares, reach antiwear object.By larger for protective housing size design, can refractory glue mud layer be set inside and outside protective housing, reach resistant to elevated temperatures object.Very easy to use, and Be very effective.
Accompanying drawing explanation
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is the structural representation of the utility model bolt;
Fig. 2 is one of structural representation of the utility model securing means;
Fig. 3 is the structural representation two of the utility model securing means.
In figure: nut 1, screw rod 2, boss 3, positioning through hole 3a, locating slot 3b, nut 4, protective housing 5, counterbore 5a, internal thread through hole 5b, the first location thorn 5c, the second location thorn 5d, fastening screw 6, first refractory glue mud layer 7, second refractory glue mud layer 8.
Embodiment
Embodiment 1
Consult shown in Fig. 1, the easy holding down bolt of one of the present utility model, comprise interconnective nut 1 and screw rod 2, be provided with boss 3 at screw rod 2 free end, boss 3 is preferably taper platform, and convenient like this installation, cone structure can play leading role.The overall structure that boss 3 and screw rod 2 are formed in one, the external diameter of boss 3 is less than screw rod 2 external diameter, like this, when bolt not easily takes out, external object can be adopted to knock boss 3 bolt is deviate from, avoid directly knocking screw rod 2 and cause thread to be out of shape, bolt is scrapped.Then, boss 3 is radially provided with positioning through hole 3a.The setting of positioning through hole 3a, the convenience that bolt is used is significantly improved, and is mainly reflected in: (1) can wear elongated bounding means, prevents bolt looseness from coming off; (2) elongated locating piece can be worn, bolt is positioned, when operator cannot touch nut 1, tightening nut on bolt can be realized quickly and easily.
Meanwhile, boss 3 outer wall is axially arranged with some locating slot 3b along screw rod 2.Locating slot 3b is the location conveniently between outside limit position part and screw rod 2.If directly contacted with the boss 3 of taper, there will be bad connection and the problem that easily loosens.
