Description
Technical field
The utility model relates to fastener technical field, refers to a kind of anti-drop bolt group especially.
Background technique
Although the function that object base can combine with object lid by existing bolt group, because sleeve and bolt are the forms be separated, when bolt by the screw of object lid be in get loose time, bolt can fall, and easily produces situation about losing; In addition, when multiple sleeve is arranged on object base, needs to assemble through sleeve one by one with multiple bolt, be also easy to produce the situation of leaking assembling.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of anti-drop bolt group, to solve the problems of the technologies described above.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of anti-drop bolt group, comprise: a sleeve and an Anti-off bolt, described sleeve is provided with a sleeve body, described sleeve body is a vertical circular body, the bottom of described sleeve body is outwardly around projection one support, projection inwardly one anticreep protuberance bottom the inwall of described sleeve body, described Anti-off bolt is provided with a body of rod, the described body of rod passes perpendicularly through to put to be stayed in described sleeve, the circumferential surface on described body of rod top is provided with a screw thread, circumferential surface projection one card division of the centre of the described body of rod, described card division is against the top side of described anticreep protuberance downwards, the bottom of the described body of rod stretches out described sleeve down, the bottom of the described body of rod is provided with a head, the width of described head is greater than the internal diameter of described sleeve body.
A top projection inwardly circular top part of described sleeve body, the centre of described circular top part is provided with a perforation, and the top of the described body of rod passes described perforation upward.
The bottom surface of described anticreep protuberance is provided with a chamfered section, and described chamfered section in the form of a ring and low inside and high outside plane of inclination.
Described head is a disk, and the central authorities of described head bottom surface are provided with a star-shaped aperture.
The beneficial effect of technique scheme of the present utility model is as follows:
Anti-drop bolt group of the present utility model is because Anti-off bolt is by the restriction of the anticreep protuberance in sleeve, be conducive to when Anti-off bolt gets loose at the screw place of object lid, Anti-off bolt only can drop down onto card division and be against position on anticreep protuberance, can not drop out by sleeve, the situation that Anti-off bolt can be avoided to lose occurs; In addition, when object base is in conjunction with multiple Anti-off bolt, owing to not needing to take bolt to combine through sleeve in addition, as long as the Anti-off bolt be provided with in fixed muffle successively, therefore, it is possible to avoid the situation of omitting, thus efficiency during raising operation and quality.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Fig. 1 to Fig. 3, the utility model embodiment provides a kind of anti-drop bolt group, one sleeve 10 and an Anti-off bolt 20, sleeve 10 is provided with a sleeve body 11, sleeve body 11 is a vertical circular body, the bottom of sleeve body 11 is outwardly around projection one support 12, projection inwardly one anticreep protuberance 14 bottom the inwall of sleeve body 11, Anti-off bolt 20 is provided with a body of rod 21, the body of rod 21 passes perpendicularly through to put to be stayed in sleeve 10, the circumferential surface on the body of rod 21 top is provided with a screw thread 211, circumferential surface projection one card division 212 of the centre of the body of rod 21, card division 212 is against the top side of anticreep protuberance 14 downwards, the bottom of the body of rod 21 stretches out sleeve 10 down, the bottom of the body of rod 21 is provided with a head 22, the width of head 22 is greater than the internal diameter of sleeve body 11.
A top projection inwardly circular top part 13 of sleeve body 11, the centre of circular top part 13 is provided with a perforation 131, and the top of the body of rod 21 passes perforation 131 upward.
The bottom surface of anticreep protuberance 14 is provided with a chamfered section 141, and chamfered section 141 in the form of a ring and low inside and high outside plane of inclination.
Head 22 is a disk, and the central authorities of head 22 bottom surface are provided with a star-shaped aperture 221.
During manufacture, be with instrument compressing Anti-off bolt 20, make the card division 212 of Anti-off bolt 20 push chamfered section 141 and by the anticreep protuberance 14 of sleeve 10, thus Anti-off bolt 20 is arranged in sleeve 10.
As shown in Figure 3 and Figure 4, sleeve 10 by under fixed hole 31 internal fixtion of embedded object base 30 upward, sleeve 10 is made to be located at object base 30 together with the Anti-off bolt 20 of inside, now limit the position of the card division 212 of Anti-off bolt 20 due to the anticreep protuberance 14 inside sleeve 10, therefore Anti-off bolt 20 can not drop out down by sleeve 10.
As shown in Figure 4 and Figure 5, object lid 32 is covered on object base 30, and make the screw 33 of object lid 32 be positioned at directly over Anti-off bolt 20, embed star-shaped aperture 221 with instrument and Anti-off bolt 20 is rotated, the screw thread 211 making Anti-off bolt 20 upward screw lock at the screw 33 of object lid 32, and the head 22 of Anti-off bolt 20 is against the bottom of the support 12 of sleeve 10, by object lid 32 with object base 30 in conjunction with fixing.
Because Anti-off bolt 20 is by the restriction of the anticreep protuberance 14 in sleeve 10, therefore when object lid 32 opened by needs, by Anti-off bolt 20 when screw 33 place of object lid 32 gets loose, Anti-off bolt 20 only can drop down onto card division 212 and be against position on anticreep protuberance 14, can not drop out by sleeve 10, therefore the loss of Anti-off bolt 20 can be avoided, in addition, when object base 30 is in conjunction with multiple Anti-off bolt, owing to not needing to take bolt to combine through sleeve 10 in addition, successively the Anti-off bolt 20 be provided with in sleeve 10 is assembled, therefore the situation forgetting assembling can also be avoided to occur.
It is more than preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
