Abstract
The utility model discloses a kind of anti-lost new structures of the bolt of sliding slot, including locating piece and bolt；Wherein, locating piece is provided with tooth hole, and bolt includes the head being linked in sequence, polished rod and tooth；Away from identical, the diameter of tooth is slightly less than the internal diameter in tooth hole for tooth and the tooth in tooth hole；The diameter of polished rod is less than the internal diameter in tooth hole；The diameter on head is more than the internal diameter in tooth hole；Bolt can pass through tooth precession or back-out locating piece.The utility model improves design structure and technique, and the uneasy assembling jump ring of energy plays anti-lost function, on the other hand can accomplish quick-replaceable bolt again, this structure is compared with previous structure, and operation is more convenient, and anti-lost effect is more preferable, and replacement bolt is more convenient.
Description
Technical Field
The utility model relates to an examine the positioning mechanism of utensil, especially relate to a novel structure is prevented losing by bolt of spout.
Background
PCF examines a frequent anti-lost mechanism that needs design bolt, like this kind of spout still takes anti-lost structure in the past, and general design has two kinds of structures: a clamp spring is arranged below a bolt, and the clamp spring has the defect that the clamp spring is easy to lose; the other is that the screw rod of the bolt is separated from the head of the bolt, and the bolt is arranged on the groove for spot welding, so that once the bolt is difficult to replace, the bolt needs to be damaged.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a novel structure is prevented losing by the bolt of spout aims at solving the problem that the inconvenient bolt replacement is easily lost or its jump ring of the spout bolt anti-loss structure of prior art.
The purpose of the utility model is realized by adopting the following technical scheme:
a novel bolt anti-lost structure of a sliding chute comprises a positioning block and a bolt; wherein,
the positioning block is provided with a tooth hole, and the bolt comprises a head, a polished rod and teeth which are sequentially connected;
the tooth pitch is the same as that of the tooth hole, and the diameter of the tooth is slightly smaller than the inner diameter of the tooth hole;
the diameter of the light rod is smaller than the inner diameter of the tooth hole;
the diameter of the head is larger than the inner diameter of the tooth hole;
the bolt can be screwed into or out of the positioning block through the teeth.
On the basis of the above embodiment, preferably, the shape of the head is a butterfly shape.
In any of the above embodiments, preferably, the outer surface of the head is provided with a concave portion or an anti-slip pattern.
On the basis of any of the above embodiments, it is preferable that a washer is further included, and the washer is disposed between the head and the tooth hole and penetrates through the polish rod.
On the basis of the above embodiment, preferably, the gasket is a multi-layer spring washer.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses a novel structure is prevented losing by bolt of spout has improved project organization and technology, can play the function of preventing losing without installing the jump ring, and on the other hand can accomplish quick replacement bolt again, and this structure is compared with structure in the past, and it is more convenient to operate, prevents losing the effect better, and it is more convenient to change the bolt.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 shows a schematic structural diagram of a novel bolt anti-lost structure of a chute provided by an embodiment of the present invention;
fig. 2 is a top view of a bolt anti-lost structure of a chute provided by an embodiment of the present invention;
fig. 3 shows a schematic structural diagram of a positioning block according to an embodiment of the present invention.
In the figure, 1, a positioning block; 2. a bolt; 101. a tooth hole; m, inner diameter of a tooth hole; 201. a head portion; 202. a polish rod; 203. a tooth.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides a novel bolt anti-lost structure of a chute, including a positioning block 1 and a bolt 2; the positioning block 1 is provided with a tooth hole 101, the tooth hole 101 and the sliding groove form a slender through hole, the bolt comprises a head 201, a polished rod 202 and teeth 203 which are sequentially connected, the tooth distance between the teeth 203 and the tooth hole 101 is the same, and the diameter of the teeth 203 is slightly smaller than the inner diameter of the tooth hole 101, namely the diameter of the polished rod 202 is smaller than the inner diameter of the tooth hole 101; the diameter of the head 201 is larger than the inner diameter of the tooth hole 101; the bolt 2 can be screwed into or out of the positioning block 1 by means of the teeth 203.
The embodiment of the utility model provides an improved project organization and technology, can not install the jump ring and play and prevent losing the function, on the other hand can accomplish the quick replacement bolt again, this structure is compared with structure in the past, and it is more convenient to operate, prevents losing the effect better, and it is more convenient to change the bolt.
The embodiment of the present invention does not limit the shape of the head 201, preferably, the shape of the head 201 may be butterfly. The butterfly-shaped head part can play a handle effect, and a user can conveniently clamp or manually apply force by using a tool to rotate the bolt.
Preferably, the outer surface of the head 201 may be provided with a recess or a non-slip pattern. This has the advantage of reducing the occurrence of slippage during the application of force to the head 201.
Preferably, the embodiment of the present invention may further include a gasket disposed between the head 201 and the tooth hole 101 and passing through the polish rod 202. This has the advantage that the connection between the head 201 and the tooth bore 101 is made more compact.
The embodiment of the utility model provides a do not do the injecing, preferred to the shape of gasket, the gasket can be multilayer spring washer. This has the advantage that the multi-layer spring washer allows a more compact construction than a conventional single-layer washer.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
