Description

Technical Field

[0001] The utility model relates to the technical field of safety locks, in particular to a safety lock with a two-way tightening and adjusting function. Background Art

[0002] In the fields of logistics, warehousing, power facility protection, etc., traditional locks can only lock one position. For application scenarios that require locking two positions at the same time, their security is insufficient. In addition, traditional locks often cannot adjust the size of the closed loop area, which limits their scope of application.

[0003] The utility model with application number CN201721352914.X relates to the field of locks, and in particular to a high-security double-lock-core structure lock, comprising a lock shell, a first lock core, a second lock core and a steel wire rope, the first lock core and the second lock core are inserted into the lock shell, a first channel is provided between the first lock core and the lock shell, a second channel is provided between the second lock core and the lock shell, a third channel is provided between the first lock core and the second lock core, the first lock core is provided with a first locking block which is pushed by a spring so that part of itself enters the first channel, the second lock core is provided with a second locking block which is pushed by a spring so that part of itself enters the second channel, one end of the steel wire rope passes through the first channel, then bends through the third channel, and finally bends again through the second channel to form two closed loops.

[0004] Although the lock lock in the above patented technology can achieve the effect of locking two closed loops, the lock lock is realized by using the first lock core and the second lock core. This structure uses one more lock core than the conventional lock lock, and this lock core can only limit the one-way pulling of the steel wire. Once the steel wire rope is pulled, the closed loop can no longer change its size. The lock lock using the above patented technology cannot operate the closed loop only once, and secondary adjustment is not allowed. In actual use, the fault tolerance rate is low, which greatly affects the construction work, and this structure lock lock has the disadvantages of complex structure, difficult assembly, and high cost.

[0030] The bidirectional tensioning and adjusting locking device comprises a lock body 100 , a pin plate 400 , a steel wire rope 500 , a spring 200 and a steel ball 300 .

[0031] A fixing hole 160, a first rope passage 110, a second rope passage 120 and a locking hole 130 are formed in the lock body 100. The first rope passage 110 passes through the left and right sides of the lock body 100 respectively. The aperture of the second rope passage 120 is slightly larger than the outer diameter of the wire rope 500. One end of the locking hole 130 of the lock body 100 is communicated with the middle side wall of the first rope passage 110, and the other end of the locking hole 130 extends to the side wall and cooperates with the lock body 100 through a plug 150.

[0032] The second rope passage 120 passes through the left and right sides of the lock body 100 . The aperture of the second rope passage 120 is slightly larger than the outer diameter of the wire rope 500 . The second rope passage 120 and the first rope passage 110 have the same direction.

[0033] The pin-tightening groove 140 is located on the bottom wall of the lock body 100, and the pin-tightening groove 140 is connected to the second rope passage 120. Chamfered surfaces are respectively provided between the bottom wall of the pin-tightening groove 140 and the groove walls on both sides.

[0034] The spring 200 and the steel ball 300 are arranged in the locking hole 130 , one end of the spring 200 abuts against the plug 150 , and the other end of the spring 200 abuts against the steel ball 300 , and the steel ball 300 extends into the first rope passage 110 .

[0035] The pin plate 400 is provided with a locking hole 410 for the wire rope 500 to pass through. The pin plate 400 can cooperate with the pin tightening groove 140. The length of the pin plate 400 is slightly longer than the depth of the pin tightening groove 140. The end face of the pin plate 400 extending into the pin tightening groove 140 and the side walls on both sides have a chamfer that cooperates with the bottom of the pin tightening groove 140.

[0036] The proximal end of the steel wire rope 500 extends into the fixing hole 160 of the lock body 100 and is embedded in the interior of the lock body 100, and the distal end of the steel wire rope 500 passes through the second rope passage 120, the engaging hole 410 on the pin plate 400, and the first rope passage 110 in sequence and then extends out of the lock body 100; during this process, the steel wire rope 500 and the lock body 100 cooperate to form two closed loops.

[0037] When in use, the wire rope 500 can move freely along the second rope passage 120, and the sizes of the two closed loops can be adjusted. According to the working conditions of the mounting of the bidirectional tensioning adjustment lock, the two closed loops are in the most suitable state, and the pin plate 400 is hammered into the pin tightening groove 140 by external force. The pin plate 400 is deformed in the pin tightening groove 140, and the pin plate 400 uses the locking hole 410 to clamp the wire rope 500 to achieve the positioning of the two closed loops.
