[0005] In view of the deficiencies in the prior art, the utility model provides a decoupling device, which solves the problems of difficulty in unlocking when overloaded and excessive wear of certain components.

[0006] (II) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The utility model provides a hook release device, which relates to the field of suspension technology and comprises a hook body, one end of which is connected to one end of a hook seat;

[0009] A rolling element is provided on the latch pin at the other end of the hook body, which can convert sliding friction into rolling friction when unlocking, thereby reducing unlocking resistance. The driving device during unlocking pulls the pull rod;

[0010] The pull rod rotates around the fixed component on the pull rod, so that the slider on the pull rod drives the latch pin to move upward, thereby unlocking the lock rod;

[0011] After the lock rod is unlocked, it moves backward along the sliding groove under the elastic force of the compression spring, and the lock rod moves backward, thereby completing the unlocking process of the lock body.

[0012] According to a further technical optimization solution, a rolling element is disposed on the latch pin, and the rolling element acts on the surface of the locking rod.

[0013] According to a further technical optimization solution, when the pull rod rotates, it drives the slider to slide upward.

[0014] According to a further technical optimization solution, when the slider moves upward, it drives the latch pin to move upward, thereby unlocking the locking rod.

[0015] According to a further technical optimization solution, the square at the tail of the locking rod contacts the sliding groove to limit its movement direction and stroke.

[0016] According to a further technical optimization solution, the locking rod contacts the rolling element when moving backward, and the rolling element rotates relative to the locking rod.

[0017] (III) Beneficial effects

[0018] The utility model provides a decoupling device. Compared with the prior art, it has the following advantages:

[0019] By setting the end of the hook body connected to the hook seat to be shorter and the unlocking end to be longer, the unlocking end is subjected to less force during use. A guide rail is provided at the other end of the pull rod, and a slider and a latch are cooperated in the guide rail. The end of the pull rope that rotates the pull rod is longer than one end of the slider, and with reference to the lever structure, it is easier to unlock and pull the pull rod. The spring cooperates with the partition and the locking rod. When the locking rod is unlocked, the compressed spring pushes the locking rod along the sliding groove, which solves the problems in the prior art that the hook body is difficult to unlock when it is overloaded, the connecting parts of the hook body are easily deformed after long-term use, making the hook body unreliable, the pull rod is difficult to pull when it is overloaded, and some parts are difficult to unlock, as well as excessive wear and tear of certain components.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The embodiment of the present application provides a decoupling device, which solves the problems of difficulty in unlocking when overloaded and excessive wear of certain components, thereby facilitating the operation of the decoupling device.

[0028] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0029] like Figure 1-Figure 4 As shown: the hook remover comprises a hook body, one end of the hook body is connected to one end of the hook seat;

[0030] A rolling element is provided on the latch pin at the other end of the hook body, which can convert sliding friction into rolling friction when unlocking, thereby reducing unlocking resistance. The driving device during unlocking pulls the pull rod;

[0031] The pull rod rotates around the fixed component on the pull rod, so that the slider on the pull rod drives the latch pin to move upward, thereby unlocking the lock rod;

[0032] After the lock rod is unlocked, it moves backward along the sliding groove under the elastic force of the compression spring, and the lock rod moves backward, thereby completing the unlocking process of the lock body, solving the problems in the prior art that the sliding friction is too large during unlocking and it is difficult to unlock, the resistance is too large during unlocking, and it is difficult to unlock by manpower alone.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example:

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the unhooker includes a hook seat 9 and a hook body 10, the hook body 10 is rotatably connected to the hook seat 9 through a second latch 11, the other end of the hook body 10 is provided with a third latch 12, the third latch 12 is provided with a rolling member 13, the other end of the hook seat 9 is provided with a hole matched with the locking rod 2, one end of the spring 3 is matched with the partition 6, and the other end is matched with the locking rod 2, the locking rod 2 is locked by the first latch 5, the first latch 5 is controlled to move by the pull rod 4, the setting of the pull rod 4 can facilitate the installation of the pull rope, the pull rod 4 is slidably connected to the slider 7 through the rotating member 8, and the slider 7 is rotatably connected to the first latch 5.

[0036] When the unhooking device is working, the object is first hung on the hook body 10, and the rotation of the pull rod 4 is used to drive the first pin 5 to move upward to unlock the locking rod 2. After the locking rod 2 is unlocked, it is pushed backward along the sliding groove 1 by the spring 3. When the locking rod 2 moves, it drives the rolling element 13 on the third pin 12 to rotate, reducing friction and making unlocking easier. When the locking rod 2 moves to a certain threshold, the limit on the hook body 10 is released, thereby realizing the unhooking of the object and completing the unhooking process.

[0037] The slider 7 is slidably matched with the pull rod 4 and rotationally matched with the first latch 5, so that when the pull rod 4 is pulled, an upward force is applied to the first latch 5 to make it move upward to unlock the lock rod 2.

[0038] like Figure 3 As shown, a rolling element 13 is mounted on the third latch 12, and lubricating oil is added between the third latch 12 and the rolling element 13 to make the rotation smoother and reduce the wear on the parts when unlocking. There is rolling friction between the rolling element 13 and the locking rod 2, which can effectively prevent the problem of difficulty in unlocking when overloaded.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
