Abstract
The utility model discloses a dysmorphism square bolt, including screw rod portion and head, its characterized in that: the head part is a special-shaped square body, four sides of the special-shaped square body enclose a parallelogram shape, and the center of the screw rod part is positioned at the center of the parallelogram shape; the upper segment of screw rod portion is the polished rod section of connecting head portion, and the well hypomere of screw rod portion is the screw thread section, and the screw thread section is equipped with the ring channel near top position, and the ring channel inside callipers has the lock ring of plastics material, and the lock ring is equipped with at the excircle and cuts off the breach and make the lock ring have shrink elasticity, and the wall thickness of lock ring equals the degree of depth of ring channel. The utility model discloses under same weight and same groove width prerequisite, can have longer contact span with the spout, guarantee that the installation is reliable stable, can realize auto-lock locking function with the threaded connection of connector simultaneously.
Description
Technical Field
The utility model relates to a fastener product, concretely relates to bolt.
Background
The bolt is by a large amount of wide application in fastening installation occasion, to the slider bolt of fastening installation in the spout, generally has regular shape's square head, and the square head is little with the contact span of spout on spout length direction, can not guarantee the reliable stability of installation, if increase the contact span under the same groove width prerequisite, needs the size of square head to increase, makes the weight of bolt heaviness and raise the cost. In addition, the self-locking function is not realized by screwing the screw thread of the threaded hole of the connecting piece by the slider bolt, and the connection looseness is easy to occur.
Disclosure of Invention
The utility model aims at providing a not enough to prior art, the utility model aims at providing a under same weight and same groove width prerequisite, can have longer contact span with the spout, guarantee that the installation is reliable stable, can realize the special-shaped cubic bolt of auto-lock locking function with the threaded connection of connector simultaneously.
Therefore, the utility model discloses an adopt following technical scheme to realize:
dysmorphism square bolt, including screw rod portion and head, its characterized in that: the head is a special-shaped square body, four sides of the special-shaped square body enclose a parallelogram shape, and the center of the screw rod part is positioned at the center of the parallelogram shape.
The upper segment of screw rod portion is the polished rod section of connecting head portion, and the well hypomere of screw rod portion is the screw thread section, and the screw thread section is equipped with the ring channel near top position, and the ring channel inside callipers has the lock ring of plastics material, and the lock ring is equipped with at the excircle and cuts off the breach and make the lock ring have shrink elasticity, and the wall thickness of lock ring equals the degree of depth of ring channel.
According to the special-shaped square bolt in the technical scheme, the regular square head shape of the traditional slide block bolt is changed by using the special-shaped square design of the head, so that a larger contact span between the special-shaped square bolt and the sliding groove is realized on the premise of the same weight and the same groove width, and the reliability and stability of installation are ensured; simultaneously, the setting up of lock ring can make the screw thread section of bolt and the screw thread tightening in-process of connector, and the lock ring that gets into the screw hole produces radial shrink, but is subject to the degree of depth of ring channel, so the excircle of lock ring can warp and hold the periodontal limit of screw hole tightly, and then plays the effect of locking screw thread to the dismouting of lock ring is all very convenient, and the bolt only needs to be changed the lock ring after using at every turn and can make the bolt possess new locking function.
To facilitate entry of the locking ring into the threaded bore, the outer circumference of the locking ring is preferably provided with a conical constriction near the lower end.
Drawings
The utility model discloses there is following figure:
figure 1 is a schematic structural view of the utility model,
fig. 2 is a bottom view of fig. 1.
Detailed Description
As shown in the figure, the utility model discloses a dysmorphism tetragonal bolt, including screw rod portion 2 and head 1, head 1 is the dysmorphism tetragonal body, and the four sides of dysmorphism tetragonal body enclose into the parallelogram shape, and the center of screw rod portion 2 is located the center of parallelogram shape, and when using, side 6 is the contact limit of bolt head 1 with the spout about the dysmorphism tetragonal body that figure 2 is shown, and the line distance of two spout contact limits is the contact span between bolt head 1 and the spout promptly. The upper segment of screw rod portion 2 is the polished rod section of connecting head portion 1, and the well hypomere of screw rod portion 2 is the screw thread section, and the screw thread section is being close to top position and is being equipped with ring channel 5, and 5 inside callipers of ring channel are equipped with the lock ring 3 of plastics material, and the excircle of lock ring 3 is being close to lower extreme position and is being equipped with the toper shrink, and lock ring 3 is equipped with in the excircle and cuts off breach 4 and make lock ring 3 have shrink elasticity, and the wall thickness of lock ring 3 equals the degree of depth of ring channel 5.
