Embodiment
Referring to figs. 1 through Fig. 2, the blank screw embodiment of the utility model band bed material is described further.
As shown in Figure 1 to Figure 2, with a blank bolt for bed material 3, comprise head 1 and screw rod 2, described head 1 is in prismatic structures, and the sidewall of described head 1 is provided with annular mounting groove 11, the bottom land of described annular mounting groove 11 is arranged around screw rod 2 central axis undulate; Also be provided with bed material 3, described bed material 3 between head 1 and screw rod 2, described bed material 3 structure ringwise, bed material 3 is arranged in described screw rod 2 and conflict in one end of bed material 3 opposing headers 1 described head 1; Described head 1 comprises the notch 4 for punch process, and described notch 4 is positioned at the side of head 1 and head 1 limit that bed material 3 side is inconsistent is relatively base 12, and described bed material 3 is projected on head 1 and forms projection plane, and described base 12 is positioned at described projection plane; Described head 1 is smooth flat with the surface of contact of bed material 3 and the surface of contact of bed material 3 and bolt head.
In the below of head 1, bed material 3 is set, during punching press, one end of the head dorsad 1 of bed material 3 is as the base 12 of punching press, the burr of the adjacent margins that head 1 and bed material 3 are conflicted, just be stamped into when punching press on bed material 3, then after punching press, bed material 3 is unloaded, burr on bed material 3 is just along with bed material 3 departs from head 1, it is convenient to remove, not only reduce the burr on workpiece limit, improve workpiece surface precision, also simplify production technology, do not need extra labour force's deburring, head 1 is smooth flat with the surface of contact of bed material 3 and the surface of contact of bed material 3 and bolt head and ensure that head 1 is when being stamped, fully can contact with bed material 3, burr can by complete punching press on bed material 3, the bottom surface of annular mounting groove 11 undulate, facilitate stressed, in use, can realize the stressed of all angles, under the environment of narrow or insufficient space, staff can utilize the instrument of speciality, from the side fastening or dismounting is carried out to bolt, especially head 1 in circular arc, screwed time, increase the stressed use to side, shape, the specification in the incorrect portion 1 of the present embodiment make restriction.
And prismatic head 1 is easy to use, processing, the setting of notch 4 expands the using scope of bolt, may be used for specific product, as after mounting, (it should be noted that, notch 4 shape in the present embodiment, specification are not unique, and the cross section that can strike out the central axis being parallel to screw rod 2 is crescent shape, rectangle etc. herein to coordinate, embed the block of special shape, because needs are arranged according to actual conditions, the present embodiment repeats no more).
The outer circumferential face of described screw rod 2 is provided with groove 21 that is some and screw rod 2 centerline axis parallel, and the central axis of each groove 21 all around described screw rod 2 is even, circumference distribution; One end of described groove 21 opposing headers 1 is through head 1 and extend one end of described head 1 screw rod 2 dorsad.
Groove 21 is set, can in use, when screw rod 2 cannot be dismantled because of the reason such as to get rusty, at head 1, by adding lubricant oil in described groove 21, then along groove 21 indwelling screw rod 2 place, the lubrication to screw rod 2 position can be realized, for convenience detach; And described groove 21 extends one end of described head 1 screw rod 2 dorsad through head 1, staff is facilitated to add lubricant oil in groove 21.
One end of described head 1 screw rod 2 dorsad is provided with oil storage tank 13, described oil storage tank 13 is provided with the oil-draining locknut 14 be connected with the sidewall thread of described oil storage tank 13, oil absorbent material 15 is provided with between described oil-draining locknut 14 and oil storage tank 13, described oil absorbent material 15 is adsorbed with lubricant oil, described each groove 21 is all communicated to the bottom of described oil storage tank 13 (in order to increase the service life, described lubricant oil will adopt not volatile, quality is good, the lubricant oil that quality is high, and last layer oil sealing can be coated with on the groove 21 mouthfuls of the bottom of groove of draining the oil, prevent oil absorbent material 15 ingress of air, and when in use, utilize the compression in space and the precipitation of lubricant oil in groove of draining the oil, oil sealing can be broken through very easily, the structure of groove 21 in head 1 is cavernous structure, each groove 21 all extends to the bottom of groove of draining the oil).
The setting of described oil storage tank 13 can be utilized, place the oil absorbent material 15 inhaled and have lubricant oil, like this can when needs lubrication, tighten described oil-draining locknut 14, utilize the bottom of oil-draining locknut 14 and the bottom squeeze oil absorbent material 15 of oil storage tank 13, thus extrude lubricant oil, then flow to screw rod 2 position along groove 21 and realize the lubrication between screw rod 2 and tapped hole; And, oil absorbent material 15 is utilized to carry out oil storage, instead of directly drain the oil, can when not needing lubrication, prevent lubricant oil from flowing out from along groove 21, when being use, also the dynamics can tightened according to oil-draining locknut 14 controls amount of compression, and realize the control used lubricant oil oil mass, structure is simple, practical, do not need to arrange extra sealing configuration to preserve lubricant oil, the lubricant oil carried also facilitates staff and uses, particularly when not having lubricant oil for subsequent use with it, simultaneously, also easy to use, once screw-driver can be used.
In addition, in order to not affect the normal use of bolt, if head 1 offers the groove for a word or Phillips screwdriver above, then the position of groove of draining the oil should be positioned at the side of head 1 central axis; Then, each groove 21 is passed in order to enable the lubricant oil in oil storage tank 13, then convenient processing again, offers the skewed slot being communicated with each groove 21, is communicated with oil storage tank 13 with a groove 21 near a side of head 1 at screw rod 2, and shunt at screw rod position, due to the groove 21 on the screw rod after installing be is formed with the inwall of mate with threaded holes with it seal connect stock, therefore, in oil mass abundance, extrude rapidly in situation, the groove 21 at interval can be crossed over, flow in alternate groove.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
