Description
Technical Field
The utility model relates to a hoist equipment field especially relates to a self-locking type horseshoe ring anticreep device.
Background
Chinese patent application No. 201821225251X discloses a hoist of area protection hasp, including rings and tool to lock, the welding of rings bottom surface has the connecting hole, and is connected with the connecting piece through connecting bolt between the connecting hole. The utility model discloses in, closed ring and tool to lock have been set up, the closed ring can be followed the axis of rotation and rotated, and insert in the tool to lock, the shell fragment promotes the locker through self elasticity and makes the locker rebound, the sawtooth locks each other with the locker, make rings be and seal the form, prevent to lift by crane the in-process, article cause danger because rocking to drop, the tool to lock surface is equipped with manual knob simultaneously, manual knob is connecting the switch spare that can rotate, rotary switch spare, switch spare extrusion locker one end, the locker is rotatory along the locker pivot, make the locker break away from with the sawtooth, can rotate out the closed ring, thereby open the hoist, lift the goods off.
The horseshoe ring lifting appliance used in the existing hoisting process on the market needs to be pulled out from the horseshoe ring after the protective bolt is used up, and operators often pull out the protective bolt and then place the protective bolt and the horseshoe ring separately, so that the horseshoe ring protective bolt is often lost, and even the horseshoe ring is still used when the protective bolt is lost, so certain potential safety hazards exist.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's above-mentioned defect, provide a self-locking type horseshoe ring anticreep device.
In order to achieve the above purpose, the utility model provides a technical scheme as follows: the utility model provides a self-locking type horseshoe ring anticreep device, includes horseshoe ring body and protection bolt, and the pinhole has been seted up in the link up of horseshoe ring body left side tip, and the corresponding pinhole of horseshoe ring body right side tip link up and has been seted up the screw, is equipped with the internal thread in the screw, and the protection bolt includes the pin pole, and the pin pole bottom corresponds the screw and is equipped with external screw thread portion, and the protection bolt inserts and passes through the mutual spiro union of external screw thread portion and screw by the pinhole outside, and the pinhole outside is supported and is pasted.
Furthermore, the diameter of the external thread part of the protection bolt is larger than that of the pin rod.
Furthermore, the limiting blocking piece is provided with a through hole corresponding to the pin hole, the diameter of the through hole is smaller than that of the pin hole, the top end of the pin rod is further provided with a partition plate, and the diameter of the partition plate is larger than that of the pin hole.
The utility model discloses an useful part is: simple structure gets into the spacing separation blade of end installation through the pinhole at the horseshoe ring, and sets up the through-hole diameter with spacing separation blade and be less than the pinhole diameter, when the protection bolt was extracted to pinhole play end, spacing separation blade can block the external screw thread portion of protection bolt, makes it unable to extract completely, makes protection bolt and horseshoe ring as an organic whole all the time, does not influence chain sling or suspender simultaneously and takes out from the horseshoe ring.
Drawings
Fig. 1 is an assembly schematic view of a self-locking horseshoe-shaped ring anti-disengaging device of the present invention;
fig. 2 is a schematic view of a protective bolt structure of a self-locking horseshoe ring anti-drop device of the present invention;
fig. 3 is a schematic view of a horseshoe ring of the self-locking horseshoe ring anti-disengaging device of the present invention.
Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1-3, a from locking type horseshoe ring anticreep device, including horseshoe ring body 1 and protection bolt 2, 1 left side tip of horseshoe ring body link up and has seted up pinhole 11, 1 right side tip of horseshoe ring body corresponds pinhole 11 and has link up and has seted up screw 12, is equipped with internal thread 13 in the screw 12, protection bolt 2 includes pin rod 21, and the corresponding screw 12 in pin rod 21 bottom is equipped with external screw thread portion 22, and protection bolt 2 inserts and passes through the mutual spiro union of external screw thread portion 22 and screw 12 by the pinhole 11 outside, and the pinhole 11 welding that supports in the pinhole 11 outside is equipped with spacing separation blade 3.
Further, the diameter of the external thread part 22 of the protection plug 2 is larger than that of the pin rod 21.
Furthermore, the limiting blocking piece 3 is provided with a through hole (not shown) corresponding to the pin hole 11, and the diameter of the through hole is smaller than that of the pin hole 11
Furthermore, the top end of the pin rod 21 is also provided with a clapboard 23, and the diameter of the clapboard 23 is larger than that of the pin hole 11.
In the above, the utility model has simple structure, the diameter of the pin rod 21 of the protective bolt 2 is adjusted according to the diameter of the pin hole 11 of the horseshoe ring body 1, so that the diameter of the pin rod is smaller than the external thread part 22, and the limit baffle 3 which is smaller than the diameter of the pin hole 11 and larger than the diameter of the pin rod 21 of the protective bolt 2 is arranged at the outer side end of the pin hole 11; the limiting baffle 3 is fixed by welding, so that the external thread part 22 is clamped to the limiting baffle 3 and cannot be completely pulled out when the protective bolt 2 is pulled out.
What has been described above is merely the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several modifications and improvements can be made, and the protection scope of the present invention should be considered.
