Abstract
The utility model provides a latching mechanism and a chain cable adopting the latching mechanism. The basal body of the latching mechanism is two opposite end faces which are provided with vertical blind holes. A pin bush is arranged between the two end faces of the basal body, and its pipe orifice is butt-jointed with the blind hole on the basal body to form a pin hole. A plurality of locking pins in the pin hole under the acting force of a compression spring are penetrated at the butt-jointed place between the pipe orifice and the blind hole to clamp the basal body and the pin bush together. In use, the locking pin and the compression spring are pressed into the pipe orifice or the blind hole firstly, and then the pin bush is inserted into the place between the two end faces of the basal body, so the locking pin can clamp the pin bush automatically to achieve the goal that a chain cable can not be opened any longer after locked tightly. When the latching mechanism is used in a chain cable, it is very convenient for the site work, and the welding has less restriction to the link material, so the probability of the chain cable to be stolen is cut down and the economic loss and the potential safety hazard brought by the theft are both decreased. This chain cable can be used as the protecting chain for the bank of the river or the sea and in other situations.
Description
Technical field
The utility model relates to a kind of latching device, also relates to a kind of chain cable that adopts this latching device.
Background technique
Existing latching device all is openable; its specific constructive form has multiple; the latch components that generally comprises matrix and cooperate with the matrix activity; wherein the major component of latch components is arranged on the outside of matrix usually; manually stir latch components; latch components is moved; privileged site sealing with matrix; make latching device be in locking states; oppositely stir latch components; the position of sealing can be opened; make latching device be in opening state; these latching devices are all for locking and unlatching repeatedly and design; therefore only be adapted to need and allow the occasion of latching device unlatching; for the occasion that must not open again after the ask for something latching device locking; these latching devices just can't adapt to; for example Jiang Di or sea wall limit are used as and enclose the protection chain cable that blocks and be made of some chain links all linked with one another; leaving certain gaps uncovered by the economic plan on the matrix of each chain link; so that be connected together with adjacent chain link by these breach; after connecting these breach are sealed; just form to connect and enclose the whole piece chain cable that blocks column; this chain cable is arranged on the open air; do not allow after installing chain link is opened; to guarantee to enclose the reliability of blocking protection; and avoid chain cable being stolen by opening chain link; because existing latching device can't be realized this purpose; therefore need to adopt the breach on the welding manner enclosed ring; because welding needs power supply and welding machine, construction is in the open air got up pretty troublesome, is particularly considering under the condition of cost; welding only is suitable for some specific materials; and the intensity of these materials is limited, can therefore the phenomenon that chain cable is stolen by pinch off be occurred through regular meeting in the practice by the pliers pinch off under stock size; not only cause loss economically, and bring the hidden danger on the safety.
The model utility content
For remedying the above-mentioned defective of prior art, the utility model provides a kind of latching device, a kind of chain cable that adopts this latching device also is provided, this latching device can only disposable locking, in case locking just can't be opened again, also just can't take apart after adopting the chain cable of this latching device to install.
The technological scheme that the utility model solves the above-mentioned technological deficiency of prior art is: a kind of latching device, comprise matrix and guide, described matrix is provided with two opposing end faces, end face is provided with the blind hole vertical with end face, described guide in a tubular form, between two end faces of described matrix, blind hole on two end faces of its pore and described matrix is docking together, form the pin-and-hole of closed at both ends, described pin-and-hole is built-in with the lock pin of plurality of moveable and the pressure spring that some and described lock pin matches, and the joint of described pore and blind hole has described lock pin to pass.
A kind of chain cable, mainly constitute by some chain links all linked with one another, wherein at least one chain link comprises matrix and guide, described matrix is belt, be provided with two opposing end faces, end face is provided with the blind hole vertical with end face, described guide in a tubular form, between two end faces of described matrix, blind hole on two end faces of its pore and described matrix is docking together, form the pin-and-hole of closed at both ends, described pin-and-hole is built-in with the lock pin of plurality of moveable and the pressure spring that some and described lock pin cooperates, and the joint of described pore and blind hole has described lock pin to pass.
The using method of the latching device that the utility model provides is: earlier lock pin and pressure spring are pressed in the pore or the blind hole on the matrix on the guide, guide is inserted between the matrix both ends of the surface, align with the blind hole on the matrix both ends of the surface respectively in the pore two ends, lock pin moves under the pressure of pressure spring, make a part of shank of same lock pin be arranged in blind hole, another part shank is arranged in pore, thus guide is stuck on the matrix, make it and to be transferred to, it is very little that gap between guide two ends and the matrix end face can be done under existing processing technique, makes to comprise that any instrument of hacksaw all can't insert.
The using method of the chain cable that the utility model provides is: chain cable can all be made of the chain link that is provided with above-mentioned latching device, also can be that the part chain link is not for establishing the enclosed ring of latching device, the part chain link is the chain link that is provided with above-mentioned latching device, wherein the chain link of latching device can be processed in factory, can be single, also can be that several rings connect into one section, elder generation's chain link that it is adjacent is inserted in the chain link that is provided with latching device during on-the-spot the installation, plug guide according to said method then, with the latching device locking on the chain link, seal the breach on the chain link matrix, so just the chain link that is provided with latching device can be coupled together with adjacent chain link, these contiguous links can be provided with latching device, can there be latching device yet, can connect into the chain cable of random lengths in this manner, and chain cable can be connected and enclose on the installing ring that blocks column, or be connected to the place that other need install chain cable.
Because the lock pin in the latching device that the utility model provides only is subjected to the effect of pressure spring in the pin-and-hole, behind the latching device locking, guide just is fixed together with matrix, latching device can't be opened, realized the purpose that the latching device disposable lock after death just can not be opened again, needs have been satisfied to this latching device, the chain cable that the utility model provides is owing to partly or entirely adopting above-mentioned latching device on the chain link, each chain link or the chain link section that constitutes chain cable can be coupled together by this latching device, form complete chain cable and it is installed in use occasion, not only greatly make things convenient for site operation, and avoided the restriction of welding to the chain ring material, make that adopting high-strength material to make chain cable becomes possibility, greatly reduced the stolen possibility of chain cable, reduced economic loss and the potential safety hazard brought because of stealing, this chain cable not only can be used as the protection chain of Jiang Di or sea wall, but also can be used as the occasion that other need chain cable arbitrarily.
