Description

Technical fields:

[0001] This utility model relates to the technical field of disassembly and assembly tools, and more specifically to a quick-release adapter. Background technology:

[0002] Existing box-type ratchet wrenches are only suitable for installing and removing bolts of one size. To change to different bolt sizes, different sizes of box-type ratchet wrenches are required. There are also box-type through-hole ratchet wrenches that can be fitted with sockets with different internal hexagonal holes. These wrenches can be fitted with sockets with corresponding internal hexagonal holes on the external hexagonal rotating part of the bolt to be installed or removed. However, these box-type through-hole ratchet wrenches are special wrenches and cannot be fitted with socket adapters, so they cannot be used with ordinary sockets, which limits their applicability.

[0003] For example, a through-hole socket and matching wrench, as described in Chinese patent application number 202420160134.9, has a ring retaining spring installed on the socket body, which allows it to be fitted onto a regular box wrench without falling off, making it widely applicable. However, it is only a through-hole socket and does not have an adapter for installation. Moreover, this type of through-hole socket is specially made and cannot be used with ordinary sockets. Utility Model Content:

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a quick-release adapter and a matching wrench. It has a ring retaining spring installed on the adapter body, so that it can be installed into the box-shaped through hole of a box-shaped ratchet wrench or a regular box-shaped wrench. Thus, it can be used to install sockets of different sizes and specifications, with good performance. Moreover, it has a quick-release push rod installed inside, which makes it quick to release when installing sockets, which is very convenient.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A quick-release adapter includes an adapter body, the adapter body including an external hexagonal connector head, and a downwardly extending square connector head formed in the middle of the bottom end face of the external hexagonal connector head.

[0007] A circular recess is formed in the center of the top surface of the external hexagonal connector head. An annular groove is formed on the upper inner sidewall of the circular recess. The annular groove extends out of the corresponding outer sidewall of the vertical wall of the external hexagonal connector head. An annular retaining spring is inserted in the annular groove. The annular retaining spring extends out of the corresponding outer sidewall of the vertical wall of the external hexagonal connector head.

[0008] The bottom surface of the circular concave hole is formed with a central concave hole, and the bottom surface of the central concave hole is formed with a central vertical through hole. The bottom end of the central vertical through hole extends out of the bottom end of the four-sided connecting head.

[0009] The quick-release push rod is installed in the circular recess, the middle recess, and the central vertical through hole.

[0010] The outer hexagonal connector head has a radially extending annular limiting edge formed on its bottom outer wall.

[0011] The quick-release push rod includes a cylindrical pressing head, which is inserted into a circular concave hole, with its outer side wall tightly against or close to the inner side wall of the circular concave hole.

[0012] The cylindrical pressing head has a downwardly extending cylindrical rod formed in the middle of its bottom surface. The cylindrical rod is inserted into the middle concave hole and the central vertical through hole. The outer side wall of the cylindrical rod is in close contact with or close to the inner side wall of the central vertical through hole.

[0013] A spring is inserted into the central recessed hole, with the top end of the spring applying force to the bottom surface of the cylindrical pressing head and the bottom end applying force to the bottom surface of the central recessed hole.

[0014] A quick-release recess is formed on one side wall of the lower part of the cylindrical rod. An outwardly extending protruding positioning part is formed on the lower inner side wall of the quick-release recess. A transverse cylindrical through hole is formed on the side wall of the square connecting head corresponding to the lower part of the protruding positioning part and the quick-release recess. The positioning bead is inserted into the transverse cylindrical through hole, and its outer wall surface is close to or tightly attached to the inner side wall of the transverse cylindrical through hole. The inside of the positioning bead extends into the lower part of the quick-release recess and rests against the outer wall surface of the protruding positioning part. The outer end of the positioning bead extends out of the outer end of the transverse cylindrical through hole.

[0015] The outstanding effect of this utility model is:

[0016] It has a ring retaining spring installed on the adapter body, which allows it to be installed into the box-shaped through hole of a box-shaped ratchet wrench or a regular box-shaped wrench. This allows it to be used with sockets of various sizes and specifications, with good performance. In addition, it has a quick-release push rod installed inside, which makes it easy to quickly release the socket when it is installed. Attached image description:

[0022] For example, see below. Figures 1 to 5 As shown, a quick-release adapter includes an adapter body 10, the adapter body 10 including an external hexagonal connector head 11, the outer side wall of the external hexagonal connector head 111 being a regular hexagonal prism.

[0023] The bottom end face of the external hexagonal connector 11 is formed with a downwardly extending square connector 12; the square connector 12 can be used to connect to a conventional sleeve to meet usage requirements.

[0024] Furthermore, a circular recess 111 is formed in the middle of the top surface of the external hexagonal connector head 11, and an annular groove 112 is formed on the upper inner sidewall of the circular recess 111. The annular groove 112 extends out of the corresponding outer sidewall of the vertical wall of the external hexagonal connector head 111. The annular retaining spring 9 is inserted in the annular groove 112, and the annular retaining spring 9 extends out of the corresponding outer sidewall of the vertical wall of the external hexagonal connector head 111.

[0025] The bottom surface of the circular concave hole 111 is formed with a central concave hole 113, and the bottom surface of the central concave hole 113 is formed with a central vertical through hole 114. The bottom end of the central vertical through hole 114 extends out of the bottom end of the square connecting head 12.

[0026] The quick-release push rod 20 is installed in the circular recess 111, the middle recess 113 and the central vertical through hole 114.

[0027] Both the central concave hole 113 and the central vertical through hole 114 are cylindrical holes.

[0028] The outer side wall of the bottom end of the external hexagonal connector 111 is formed with a radially extending annular limiting edge 115. This annular limiting edge 115 allows the external hexagonal connector 11 to be inserted into the Phillips head hole of the wrench, and the top surface of the annular limiting edge 115 presses against the bottom surface of the wrench connector to achieve limiting.

[0029] Furthermore, the quick-release push rod 20 includes a cylindrical pressing head 21, which is inserted into a circular recess 111, with its outer side wall closely attached to or close to the inner side wall of the circular recess 111.

[0030] The cylindrical pressing head 21 has a downwardly extending cylindrical rod 22 formed in the middle of its bottom surface. The cylindrical rod 22 is inserted into the middle concave hole 113 and the central vertical through hole 114. The outer side wall of the cylindrical rod 22 is in close contact with or close to the inner side wall of the central vertical through hole 114.

[0031] A spring 1 is inserted into the central recess 113. The top end of the spring 1 applies force to the bottom surface of the cylindrical pressing head 21, and the bottom end applies force to the bottom surface of the central recess 113.

[0032] Furthermore, the bottom end face of the cylindrical rod 22 is flush with the bottom end face of the square connecting head 12;

[0033] A quick-release recess 23 is formed on the lower side wall of the cylindrical rod 22. An outwardly extending protruding positioning part 24 is formed on the lower inner side wall of the quick-release recess 23. A transverse cylindrical through hole 121 is formed on the side wall of the square connecting head 12 corresponding to the lower part of the protruding positioning part 24 and the quick-release recess 23. The positioning bead 2 is inserted into the transverse cylindrical through hole 121, and its outer wall surface is close to or tightly attached to the inner side wall of the transverse cylindrical through hole 121. The interior of the positioning bead 2 extends into the lower part of the quick-release recess 23 and rests against the outer wall surface of the protruding positioning part 24. The outer end of the positioning bead 2 extends out of the outer end of the transverse cylindrical through hole 121. An extension is formed on the inner side wall of the outer end of the transverse cylindrical through hole 121. The corresponding wall surface of the outer side of the positioning bead 2 rests against the inner side of the extension.

[0034] In this embodiment, the external hexagonal connector head 11 can be inserted into the box-shaped socket of a common box-shaped wrench connector or installed into the box-shaped socket of a box-shaped ratchet wrench (the common box-shaped wrench can be a single-purpose or dual-purpose wrench; one end of the dual-purpose wrench has a box-shaped through hole, and the other end has an open slot). Its top extends out of the top surface of the box-shaped socket, so that the bottom surface of the outer side wall of the annular retaining ring 9 protruding from the external hexagonal connector head 11 presses against the top surface of the connector head, thus achieving installation. Meanwhile, the top surface of the annular limiting edge 115 presses against or approaches the bottom surface of the wrench connector head, thus achieving limiting.

[0035] Then, the connecting end of the sleeve can be inserted into the corresponding square connecting head 12 to achieve connection, thus satisfying the conventional sleeve connection use. When disassembly is required, simply press down on the cylindrical pressing head 21 to make the cylindrical rod 22 descend, causing the spring 1 to compress. The positioning bead 2 is in the quick release recess 23 and is not pressed by the protruding positioning part 24. In this way, the part of the positioning bead 2 that extends outward can enter the transverse cylindrical through hole 121, and the sleeve will fall off quickly, achieving a quick release effect with good performance.

[0036] With the wrench of this embodiment installed, different sizes of conventional sockets can be fitted as needed, making it widely applicable and effective.
