Description

Technical Field

[0001] This utility model relates to the field of seat belt technology, and in particular to a seat belt with replaceable buckles. Background Technology

[0002] In existing seat belt structures, the buckle is typically riveted to the connector or integrally molded. When the buckle wears out, corrodes, or is accidentally damaged over time, the entire seat belt assembly must be replaced, resulting in high maintenance costs and wasted resources. Some detachable designs suffer from structural complexity, require specialized tools for replacement, and have insufficient connection stability, which can easily lead to safety hazards. For example, traditional plug-in buckles may accidentally disengage under severe impact, or the cumbersome disassembly process affects replacement efficiency. Therefore, there is an urgent need for a seat belt buckle structure that is easy to operate, has a reliable connection, and supports quick buckle replacement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a safety belt with replaceable buckles.

One end of the buckle is used to insert a buckle head, and the other end of the buckle is connected to a connecting seat plate. The connecting seat plate is used to be installed on a buckle connecting seat. The buckle connecting seat has an installation groove for installing the connecting seat plate. The buckle connecting seat has symmetrical movable cavities on both sides of the installation groove. Each movable cavity has a limiting insert plate that is slidably fitted to it to lock the connecting seat plate. Each movable cavity has a connecting cavity on one side. Limiting components are symmetrically installed in the connecting cavities on both sides. The limiting components are locked to the buckle connecting seat by a fixing component.

[0005] In addition, a preferred structure is that a limiting post is provided in the middle of the mounting groove, the mounting groove and the movable cavity are directly connected through a socket, and the limiting plate moves into the mounting groove through the socket.

[0006] In addition, the preferred structure is that each of the movable cavities is provided with a sliding plate, on which a limiting insert plate slides and engages, and each insert cavity is provided with a screw hole laterally, and the screw hole extends to the side walls on both sides of the locking connector, and the fixing component is screwed into the screw hole.

[0007] In addition, a preferred structure is that the limiting insert plate includes an insert block for locking the connecting seat plate, and a sliding groove is provided on the plate body of the limiting insert plate on one side of the insert block.

[0008] In addition, a preferred structure is that a limiting hole is formed through the middle of the connecting seat plate, the limiting hole cooperates with the limiting post, and slots are symmetrically formed on both sides of the connecting seat plate, the slots are used to limit the position of the insert block.

[0009] In addition, a preferred structure is that the limiting member includes a limiting block, which is installed in the movable cavity.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-8A seat belt with replaceable buckles includes a buckle 1. One end of the buckle 1 is used to insert a buckle head 2, and the other end of the buckle 1 is connected to a connecting seat plate 5. The connecting seat plate 5 is used to install on a buckle connecting seat 4. The buckle connecting seat 4 has an installation groove 41 for installing the connecting seat plate 5. The buckle connecting seat 4 has symmetrical movable cavities 44 on both sides of the installation groove 41. Each movable cavity 44 is slidably fitted with a limiting insert 7 for locking the connecting seat plate 5. Each movable cavity 44 has a connecting cavity 46 on one side. Each of the two cavity 46 has a symmetrically installed limiting member 8. The limiting member 8 is locked to the buckle connecting seat 4 by a fixing member 6. The limiting member 8 is used to lock the limiting insert 7 to prevent it from moving.

[0015] Furthermore, a limiting post 42 is provided in the middle of the mounting groove 41. The mounting groove 41 and the movable cavity 44 are directly connected through the socket 43. The limiting plate 7 moves into the mounting groove 41 through the socket 43. The limiting plate 7 can effectively lock the connecting seat plate 5.

[0016] In addition, each of the movable cavities 44 is provided with a sliding plate 45, on which a limiting insert plate 7 slides and engages. Each of the insert cavities 46 is provided with a horizontally opened screw hole 461, which extends to the side walls on both sides of the locking connecting seat 4. The fixing component 6 is screwed into the screw hole 461. The limiting insert plate 7 includes an insert block 71 for locking the connecting seat plate 5. A sliding groove 72 is opened on the plate body of the limiting insert plate 7 on one side of the insert block 71. The insert block 71 is used to lock into the slot 51.

[0017] Meanwhile, a limiting hole 52 is provided in the middle of the connecting base plate 5. The limiting hole 52 cooperates with the limiting post 42. Slots 51 are symmetrically provided on both sides of the connecting base plate 5. The slots 51 are used to cooperate with the limiting of the plug 71.

[0018] The limiting component 8 includes a limiting block 81, which is installed in the movable cavity 44. A retaining plate 83 is fixedly connected to one side wall of the limiting block 81. The retaining plate 83 is used to be inserted into the insertion cavity 46. The through hole 84 on the retaining plate 83 is coaxial with the screw hole 461. A pinch block 82 is provided on the side wall of the limiting block 81 adjacent to the retaining plate 83. The pinch block 82 is convenient for the operator to pick up.

[0019] In this embodiment, when it is necessary to replace the buckle 1 of the seat belt connecting buckle head 2, the fixing parts 6 on both sides are loosened from the screw holes 461, so that the fixing parts 6 no longer pass through the through hole 84 to lock the card plate 83. At this time, the limiting block 81 that abuts against the limiting insert 7 and restricts its lateral movement on the slide plate 45 can be taken out from the movable cavity 44 by the pinch block 82. At this time, the limiting insert 7 can be moved in the movable cavity 44 to separate the insert 71 from both sides of the slot 51. The connecting seat card plate 5 and the buckle connecting seat 4 can be quickly separated, so that the buckle 1 can be removed from the buckle connecting seat 4 connected to the buckle connecting head 3 for replacement. In addition, the limiting hole 52 works with the limiting post 42 to start the fixing and positioning function, improving the firmness of the connection.

[0020] In this utility model, the locking buckle 1 can be disassembled and installed by the cooperation of the limiting insert plate 7 and the slot 51 of the connecting seat plate 5, combined with the detachable limiting component 8. It is not necessary to disassemble the locking buckle 1, the locking buckle connector 3, and the locking buckle connector 4 as a whole. The insert block 71 of the limiting insert plate 7 is inserted into the slot 51 to form a lateral constraint. With the cooperation of the limiting component 8 to fix the limiting insert plate, it is ensured that the locking buckle has no risk of falling off under impact load. The threaded locking design of the fixing component 6 through the limiting component 8 and the screw hole 461 prevents the parts from loosening and failing.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
