According to the depth of the screw hole formed in the part, the top plate is held to pull the pull rod, the pull rod drives the clamping ball to extrude the elastic clamping block between the clamping grooves and then is combined with the clamping groove at the designated position, so that the pull rod extends downwards to a corresponding length, the redundant length of the screw hole is supplemented, an operator feels obvious resistance in the process of screwing the bolt, the resistance is the position for locking the preset depth of the bolt, the bolt can adjust the locking positions of multiple groups of fixed depths through the matching of the rubber column and the pull rod, and the using effect of the bolt is improved.
Description
Technical Field
The utility model relates to the technical field of bolts, in particular to a bolt with controllable locking depth.
Background
Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.
At present, the existing bolt still has the shortcomings, the thread height of the existing bolt is relatively fixed, when the bolt is used for fastening a part, the depth of the threaded hole formed in the part is not always consistent with the thread height of the bolt, and a mechanism capable of locking and adjusting the depth is not arranged in the bolt, so that the surface of the part is easy to deform and damage due to the fact that the screwing depth cannot be mastered in the screwing process of the bolt, and the using effect of the bolt is reduced.
Disclosure of Invention
The utility model aims to: in order to solve the problems, the locking depth controllable bolt is provided.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a controllable formula bolt of closure degree of depth, includes nut and screw rod, the perforation has been seted up to the table wall in the vertical end of screw rod, table wall fixed mounting has the rubber column in the perforation, the vertical draw-in groove of seting up the multiunit and being vertical distribution of table wall in the rubber column, and the multiunit equal elastic connection has the elasticity fixture block between adjacent two sets of in the draw-in groove, the rubber column is connected with the card ball through the draw-in groove block, table wall fixed mounting has the pull rod in the card ball, just the open end fixed mounting of pull rod has the roof.
As a further description of the above technical solution:
the rubber column is in interference fit with the through hole.
As a further description of the above technical solution:
and an elastic cushion layer is fixedly arranged on one side of the screw cap close to the screw rod.
As a further description of the above technical solution:
the pull rod and the top plate are integrally formed.
As a further description of the above technical solution:
and rough grains are arranged on one side, away from the pull rod, of the top plate.
As a further description of the above technical solution:
at least one group of the clamping balls are distributed on the outer surface wall of the pull rod in an equidistant straight line.
In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:
according to the utility model, before the bolt locks the parts, the top plate is held to pull the pull rod according to the depth of the screw hole formed in the parts, the pull rod drives the clamping ball to extrude the elastic clamping block between the clamping grooves and then is combined with the clamping groove at the designated position, so that the pull rod extends downwards to a corresponding length, and the redundant length of the screw hole is supplemented, therefore, in the process of screwing the bolt, when an operator feels obvious resistance, the resistance is the position for locking the preset depth of the bolt, and the bolt can be adjusted at multiple groups of locking positions with fixed depth through the matching of the rubber column and the pull rod, so that the using effect of the bolt is improved.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a controllable formula bolt of closure degree of depth, including nut 1 and screw rod 2, the perforation 3 has been seted up to the table wall in the 2 vertical ends of screw rod, table wall fixed mounting has rubber column 4 in the perforation 3, rubber column 4 interior table wall is vertical to be seted up the multiunit and is the draw-in groove 8 of vertical distribution, and equal elastic connection has elasticity fixture block 5 between adjacent two sets of in the multiunit draw-in groove 8, rubber column 4 is connected with card ball 6 through draw-in groove 8 block, table wall fixed mounting has pull rod 7 in the card ball 6, and the open end fixed mounting of pull rod 7 has roof 9.
Specifically, as shown in fig. 1, the glue column 4 is in interference fit with the through hole 3, so that the position stability of the glue column 4 is ensured.
Specifically, as shown in fig. 1, an elastic cushion layer is fixedly installed on one side of the nut 1 close to the screw rod 2, so that when the bolt is completely combined with a part, the bottom of the nut 1 cannot cause damage to the outer surface wall of the part.
