Description

Technical Field

[0001] This utility model belongs to the field of plugs and relates to a quick-connect connector disassembly tool. Background Technology

[0002] Quick-connect couplings are the most convenient plug-and-play connection method, especially advantageous in challenging environments where air pipe connections are difficult. To ensure a secure connection, quick-connect couplings are easy to insert but difficult to remove. Currently, removal is done manually. Manual removal presents two main problems: 1. The contact between the hand and the coupling's outer shell is not tight, making it difficult and strenuous to pull out; 2. Uneven force distribution on the coupling's outer shell can easily damage it. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-connect connector disassembly fixture, which solves the problem that the current method of disassembling quick-connect connectors is mainly manual disassembly without dedicated disassembly tools, which is not only laborious to disassemble but also easy to damage the connector.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A quick-connect connector disassembly fixture includes a pair of pliers. The pliers include two cross-arranged and hinged pliers bodies. Each pliers body includes a pliers head and a pliers handle connected in sequence. The rear root of the pliers head is connected to the pliers handle. A clamping block is installed at the front end of the pliers head. The clamping blocks at the front ends of the two pliers head are spliced ​​together to form a clamp for holding the quick-connect connector. The clamp has a clamping cavity. A retaining ring is installed at the end of the quick-connect connector. The clamping cavity of the clamp matches the shape of the retaining ring, and the retaining ring engages with the clamping cavity to achieve clamping of the quick-connect connector by the clamp.

[0006] This utility model uses a pair of pliers as a base and installs a clamp on the pliers head that matches the retaining ring at the end of the quick-connect connector. The clamp replaces the manual gripping of the retaining ring of the quick-connect connector, which not only strengthens the gripping stability but also makes the retaining ring bear force evenly. This solves the problem that the current method of disassembling quick-connect connectors is mainly done manually without dedicated disassembly tools, which is not only laborious but also easy to damage the connector.

[0007] Furthermore, each outer wall of the clamping block is provided with an anti-slip pad, the anti-slip pad having a thickness of 2-3mm.

[0008] The anti-slip pad enhances the connection between the clamp and the snap ring of the quick-connect structure.

[0009] Furthermore, the surface of the anti-slip pad located on the inner wall of the clamping block is evenly distributed with anti-slip patterns, and grooves are formed between adjacent anti-slip patterns. The anti-slip patterns are located on the inner wall of the clamping cavity and contact the outer wall of the retaining ring.

[0010] Furthermore, the pliers head is a straight plate, and with the pliers head as a reference, the clamping block and the corresponding pliers head form an angle.

[0011] The angle between the clamping block and the corresponding pliers head in this invention is to accommodate quick-connect connectors with different installation angles.

[0012] Furthermore, the pliers handles are arc-shaped, with two pliers handles positioned opposite each other. The front end of each pliers handle is connected to the rear root of the corresponding pliers head, and a locking latch is provided between the tail ends of the two pliers handles to lock them together.

[0013] The pliers in this invention are based on existing technology and are similar to scissors. By controlling the two handles, the two pliers heads can be opened and closed. After the clamps formed on the two pliers heads hold the retaining ring of the quick-connect connector, the two handles are locked with a latch. When it is necessary to open the two pliers heads, the latch is released.

[0014] Furthermore, the outside of the pliers handle is covered with a rubber sleeve, and the outer wall of the rubber sleeve is evenly distributed with anti-slip texture.

[0015] Furthermore, the clamping block and the corresponding clamping head form a 90° angle, the front end of the clamping head is connected and fixed to the top surface of the clamping block, and the bottom of the clamping block forms a clamping cavity.

[0016] This utility model applies to quick-connect couplings that are installed horizontally.

[0017] Furthermore, the lock includes a matching buckle and a buckle head. The buckle is installed at the tail of one of the two pliers handles, and the buckle head is installed at the tail of the other pliers handle. The buckle head is engaged with the buckle ring to lock the two pliers handles. The buckle head, buckle ring and corresponding pliers handle tails are respectively connected and fixed by ropes.

[0018] The locking structure in this invention is existing technology, such as the locking mechanism of existing car seat belts.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. This utility model discloses a quick-connect connector disassembly fixture based on a pair of pliers. A clamp adapted to the retaining ring at the end of the quick-connect connector is installed on the pliers head. The clamp replaces the manual gripping of the retaining ring, which not only strengthens the gripping stability but also ensures even force distribution on the retaining ring. This solves the problem that current quick-connect connector disassembly methods mainly rely on manual disassembly without dedicated tools, resulting in laborious disassembly and easy damage to the connector.

[0021] 2. In this utility model, after the clamps formed on the two pliers hold the retaining ring of the quick-connect connector, the two pliers handles are locked with a locking buckle, which indirectly plays a role in locking and limiting the clamps, preventing the clamps from loosening during the disassembly of the connector.

[0030] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0031] Example 1

[0032] like Figures 1-3 As shown in the preferred embodiment of this utility model, a quick-connect connector disassembly fixture includes a pair of pliers. The pliers include two cross-arranged and hinged plier bodies 1. Each plier body includes a plier head 11 and a plier handle 12 connected in sequence. The rear root of the plier head 11 is connected to the plier handle 12. A clamping block 2 is installed at the front end of the plier head 11. The clamping blocks 2 at the front ends of the two plier heads 11 are spliced ​​together to form a clamp for holding a quick-connect connector 3. The clamp has a clamping cavity. A retaining ring 31 is installed at the end of the quick-connect connector 3. The clamping cavity of the clamp matches the shape of the retaining ring 31, and the retaining ring 31 is engaged in the clamping cavity to achieve clamping of the quick-connect connector 3 by the clamp.

[0033] Each outer wall of the clamping block 2 is provided with an anti-slip pad 4, the anti-slip pad 4 having a thickness of 2-3mm.

[0034] The surface of the anti-slip pad 4 located on the inner wall of the clamping block 2 is evenly distributed with anti-slip patterns, and grooves are formed between adjacent anti-slip patterns. The anti-slip patterns are located on the inner wall of the clamping cavity and contact the outer wall of the retaining ring 31.

[0035] The pliers handle 12 has an arc-shaped structure, and the two pliers handles 12 are arranged opposite each other. The front end of the pliers handle 12 is connected to the rear root of the corresponding pliers head 11. A locking buckle 5 is provided between the tail ends of the two pliers handles 12 to lock the two pliers handles 12. The locking buckle 5 includes a matching buckle ring and a buckle head. The buckle ring is installed at the tail end of one pliers handle 12, and the buckle head is installed at the tail end of the other pliers handle 12. The buckle head is inserted into the buckle ring to lock the two pliers handles 12. The buckle head, buckle ring and the tail end of the corresponding pliers handle 12 are respectively connected and fixed by a rope.

[0036] The plier handle 12 is covered with a rubber sleeve 6, and the outer wall of the rubber sleeve 6 is evenly distributed with anti-slip texture.

[0037] The method of using this utility model is as follows: Manually hold the pliers handles and open and close the two pliers handles to open and close the two pliers heads. First, open the two pliers heads to increase the distance between them, allowing the retaining ring of the quick-connect connector to enter between the clamping blocks of the two pliers heads. Then, by controlling the pliers handles, close the two pliers heads, reducing the distance between the clamping blocks. After the clamping blocks of the two pliers heads engage to clamp the retaining ring of the quick-connect connector, use a locking mechanism to lock the two pliers handles, indirectly locking the two clamping blocks. Finally, hold the pliers handles and pull the connector outwards.

[0038] This utility model uses a pair of pliers as a base and installs a clamp on the pliers head that matches the retaining ring at the end of the quick-connect connector. The clamp replaces the manual gripping of the retaining ring of the quick-connect connector, which not only strengthens the gripping stability but also makes the retaining ring bear force evenly. This solves the problem that the current method of disassembling quick-connect connectors is mainly done manually without dedicated disassembly tools, which is not only laborious but also easy to damage the connector.

[0039] Example 2

[0040] Based on Embodiment 1, in this embodiment, the pliers head 11 is a straight plate, and the clamping block 2 forms an angle with the corresponding pliers head 11, with the pliers head 11 as the reference. Preferably, the clamping block 2 forms a 90° angle with the corresponding pliers head 11, the front end of the pliers head 11 is connected and fixed to the top surface of the clamping block 2, and the bottom of the clamping block 2 forms a clamping cavity.

[0041] The angle between the clamping block and the corresponding pliers head in this invention is to accommodate quick-connect fittings with different installation angles. Quick-connect fittings are usually installed horizontally. Therefore, this invention prefers a connection method between the clamping block and the pliers head, namely: when the pliers head is placed horizontally, the clamping block and the pliers head form a 90° angle, which is convenient to use.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
