Description

Technical Field

[0001] This utility model relates to the field of snap ring technology, specifically a handcuff-type snap ring that is not easily detached. Background Technology

[0002] In traditional handcuff devices, the snap ring plays a crucial role in locking and unlocking. However, some existing snap ring designs have structural defects. Simple plate snap rings are prone to popping out of the slot or loosening when subjected to large external impacts or prolonged vibrations. Accidental detachment of the snap ring can cause the handcuff device to lose its restraining function, thus posing a safety risk.

[0003] Traditional snap ring fastening methods are often quite simple, relying solely on the simple engagement of the snap ring and the slot. This simple fastening method lacks sufficient redundancy. Once the slot or any part of the snap ring is worn or deformed, it will affect the fastening effect of the snap ring. Therefore, we propose a handcuff-type snap ring that is not easy to fall off. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a handcuff-type retaining ring that is not easy to fall off, so as to solve the problems mentioned in the background art.

[0006] Two technical solutions

[0007] To achieve the above objectives, this utility model provides the following technical solution: a handcuff-type snap ring that is not easily detached, comprising a first half-ring, one end of which is rotatably connected to a second half-ring, a fixing plate one fixedly installed on the outer side of the first half-ring, a fixing plate two fixedly installed on the outer side of the second half-ring, an insert strip fixedly installed on one end of the first half-ring, a slot provided on one end of the second half-ring, a first pin threaded onto the top of the insert strip, an insertion hole provided on the slot, and tension springs provided in the fixing plate one and the fixing plate two.

[0008] Preferably, a second pin is fixedly connected to the first half-ring and the second half-ring.

[0009] Preferably, a metal ring is fixedly installed at one end of the tension spring, and a metal hook is fixedly installed at the other end of the tension spring.

[0010] Preferably, the first pin secures the insert and the slot through the insertion hole.

[0011] Preferably, the insert and the slot have the same shape and correspond to each other.

[0012] Preferably, the first fixing piece has a first connecting groove, and the second fixing piece has a second connecting groove.

[0013] Compared with the prior art, this utility model provides a handcuff-type retaining spring that is not easy to fall off, which has the following beneficial effects: The handcuff-type retaining spring is not easy to fall off, which means that its structure is more stable. The stable retaining spring structure will not be deformed or damaged due to normal opening and closing operations or occasional external impacts. In harsh environmental conditions, such as humid, muddy or dusty environments, the retaining spring can maintain its performance. The retaining spring can effectively resist the interference of these environmental factors and ensure the normal operation of the retaining spring. Compared with easily falling off retaining springs, this retaining spring can withstand more cycles of use, reducing the frequency of replacing the entire handcuff due to spring damage, thereby reducing costs.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-3 As shown, a shackle-type snap ring that is not easy to fall off includes a first half ring 1, a second half ring 2 rotatably connected to one end of the first half ring 1, a fixing plate 3 fixedly installed on the outer side of the first half ring 1, a fixing plate 5 fixedly installed on the outer side of the second half ring 2, an insert 7 fixedly installed at one end of the first half ring 1, a slot 8 opened at one end of the second half ring 2, a first pin 9 threadedly installed on the top of the insert 7, an insertion hole 10 opened on the slot 8, and a tension spring 11 provided in the fixing plate 3 and the fixing plate 5.

[0020] Furthermore, a second pin 14 is fixedly connected to the first half-ring 1 and the second half-ring 2.

[0021] Through the above technical solution, the fixed connection of the second pin 14 can effectively connect the first half ring 1 and the second half ring 2 together. When the frame is subjected to external impact or bears heavy loads, the pin can prevent relative displacement between the half rings.

[0022] Furthermore, a metal ring 12 is fixedly installed at one end of the tension spring 11, and a metal hook 13 is fixedly installed at the other end of the tension spring 11.

[0023] Through the above technical solutions, the metal ring 12 provides a convenient way to connect with other components, while the metal hook 13 provides another connection possibility, making assembly convenient and quick.

[0024] Furthermore, the first pin 9 secures the insert 7 and the slot 8 through the insertion hole 10.

[0025] Through the above technical solution, the cooperation between the pin and the socket 10 enables precise positioning of the insert 7 and the slot 8. When the first pin 9 is inserted into the socket 10, it ensures that the insert 7 is accurately located in the predetermined position in the slot 8, making the connection between the insert 7 and the slot 8 tighter.

[0026] Furthermore, the insert 7 and the slot 8 have the same shape and correspond to each other.

[0027] Through the above technical solution, the identical and corresponding shapes of the inserts 7 can be perfectly inserted into the slots 8. Their identical shape design can ensure the accuracy of assembly, thereby avoiding the impact on the performance of the equipment due to assembly errors.

[0028] Furthermore, a connecting groove 4 is provided in the fixing plate 3, and a connecting groove 6 is provided in the fixing plate 5.

[0029] Through the above technical solutions, connecting groove 4 and connecting groove 6 provide more options for connecting with other components. The connecting grooves provide a certain degree of adjustability. By adjusting the position of the connecting parts in the connecting grooves, different installation position requirements of the rods can be adapted.

[0030] Working principle: First, open the first half ring 1 and the second half ring 2, then place the frame on the part to be installed, insert the insert 7 into the slot 8, and insert the first pin 9 at the top of the insert 7 into the insertion hole 10 to secure the insert 7 in the slot 8. Then, the metal hook 13 on the tension spring 11 hooks the fixing piece 5 through the connecting groove 2 6 to secure it to the part. When disassembling, simply remove the metal hook 13, reverse the first pin 9 to pull it out of the insertion hole 10, and then pull the insert 7 out of the slot 8 to remove it.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
