Technical Field

[0001] The utility model belongs to the technical field of buckles, and particularly relates to a novel safety buckle. Background Art

[0002] With the advancement of materials science, safety buckles are usually made of high-strength, wear-resistant and corrosion-resistant materials, such as stainless steel, high-strength aluminum alloy, engineering plastics, etc., to ensure stability and durability in extreme environments; safety buckles, as an important safety protection device, are widely used in various fields, including but not limited to children's car seats, outdoor sports equipment, construction safety equipment, high-altitude work protective equipment, etc.

[0003] The traditional buckle is clamped inside the buckle seat by pressing, and the two outer side walls of the pressing part of the buckle are usually exposed to the outside. During use, if the user accidentally presses the two side walls of the buckle, the buckle can easily detach from the buckle seat, posing a safety hazard to the user when working at height or carrying heavy objects.

[0004] Therefore, in order to improve the safety of the buckle and ensure the safety of the user during the use of the buckle, a new type of safety buckle is needed to solve the existing problems. Utility Model Content

[0005] In view of this, the utility model aims at the deficiencies of the prior art and provides a new type of safety buckle. Under the connection of the T-shaped pillar, the clamping ring and the spring, the card block can only be disengaged from the slot when the L-shaped support rod is pulled outward, which can avoid accidental contact with the buckle and cause the card block to be disengaged from the slot, thereby ensuring the safety of the buckle when in use.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a new type of safety buckle, including a base, one end of the base is equipped with a support plate through a rotating shaft, the support plate rotates around the rotating shaft, a circular groove is opened on the side wall of the end of the support plate away from the rotating shaft, a T-shaped pillar is horizontally installed inside the circular groove, the T-shaped pillar passes through one end of the clamping ring, the end extending outward of the clamping ring is closed, and a clamping ring is sleeved on the T-shaped pillar, that is, the clamping ring limits the T-shaped pillar to prevent the clamping ring from detaching from the T-shaped pillar, and a spring is also fixedly installed on the inner bottom of the circular groove, the spring is surrounded and installed on the outer side wall of the T-shaped pillar, the other end of the spring is fixedly connected to the end of the clamping ring, the end extending outward of the clamping ring is fixedly installed with an L-shaped support rod, the other end of the L-shaped support rod is connected with a clamping block, and a clamping groove is opened on the side wall of the end of the base away from the rotating shaft, the clamping groove and the clamping block correspond to each other, that is, the L-shaped support rod is driven by the spring and the clamping ring to make the clamping block enter the clamping groove to complete the buckling.

[0007] The circular groove, T-shaped pillar, clamping ring, spring, L-shaped support rod, clamping block and clamping groove are arranged in two groups, which are symmetrically distributed with respect to the vertical center plane of the support plate; that is, the components are arranged in two groups to enhance the safety of the buckle components when used.

[0008] A connecting rod is fixedly installed between the two L-shaped support rods and connected to the inner side wall at the corner of the L-shaped support rod, that is, the connecting rod can facilitate users to operate two sets of buckle components at the same time.

[0009] A rotating rod is also installed on the top of the base, the bottom of the rotating rod is sleeved in the hole on the top of the base, a clamping plate is fixedly installed on the top of the rotating rod, and a rotating buckle is installed on the top of the clamping plate, that is, the rotating rod drives the clamping plate to rotate around the rotating rod.

[0010] A through hole is provided on the support plate, and the through hole passes through the upper and lower side walls of the support plate. When the support plate is buckled, the center of the through hole corresponds to the center of the rotating rod, that is, the rotating buckle limits the opening and closing of the support plate.

[0011] A handle is also installed on the top of the support plate, that is, the handle facilitates the opening and closing of the support plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Firstly, under the action of the spring, T-shaped pillar and the retaining ring, the card block is installed inside the card slot. When the card block is disengaged from the card slot, the L-shaped support rod can only be pulled outward. Under the expansion and contraction of the spring, the retaining ring moves horizontally on the T-shaped pillar before it can be disengaged. It is not easy for the traditional buckle to be disengaged from the card slot, thereby improving the safety of the buckle assembly during use and ensuring the safety of the staff.

[0014] Secondly, the connecting rod allows the user to hold the middle part of the connecting rod and pull the L-shaped support rod outward, so that the blocks in the two components are simultaneously inserted into the slots, which is convenient for operation. At the same time, the setting of the two sets of fasteners can improve the firmness of the fasteners.

[0015] Thirdly, by twisting the rotating buckle, the card plate is driven to rotate around the rotating rod under the action of the rotating rod, and the rotating card plate and the through hole are overlapped or cross-shaped, which can further limit the opening and closing of the support plate and enhance the safety of use.

[0024] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0025] like Figure 1-5As shown, a new type of safety buckle includes a base 101, one end of the base 101 is installed with a support plate 103 through a rotating shaft 102, the support plate 103 rotates around the rotating shaft 102, and a circular groove 104 is opened on the side wall of the end of the support plate 103 away from the rotating shaft 102, and a T-shaped pillar 105 is horizontally installed inside the circular groove 104, the cross section of the T-shaped pillar is T-shaped, the T-shaped pillar 105 passes through one end of a clamping ring 106, and the end of the clamping ring 106 extending outward is closed. A clamping ring 106 is sleeved on the T-shaped pillar 105, and the clamping ring 106 can move horizontally on the T-shaped pillar 105, that is, the clamping ring 106 limits the T-shaped pillar 105 to prevent the clamping ring 106 from detaching from the T-shaped pillar 105, the end of the T-shaped pillar 105 reciprocates at the protruding part of the clamping ring 106, and is limited at the recessed part of the clamping ring 106 to prevent the clamping ring 106 from falling off, and the circular groove 104 is provided with a clamping ring 106. 4 is also fixedly installed with a spring 107 at the inner bottom, and the spring 107 is installed around the outer side wall of the T-shaped pillar 105. The other end of the spring 107 is fixedly connected to the end of the snap ring 106. The end of the snap ring 106 extending outward is fixedly installed with an L-shaped support rod 108, and the other end of the L-shaped support rod 108 is connected with a clamping block 109. A clamping groove 110 is provided on the side wall of the end away from the rotating shaft 102 on the base 101, and the clamping groove 110 and the clamping block 109 correspond to each other, that is, the L-shaped support rod 108 is driven by the spring 107 and the snap ring 106 to make the clamping block 109 clamped into the clamping groove 110 to complete the buckling. When the clamping block 109 is separated from the clamping groove 110, the L-shaped support rod 108 can only be pulled outward. Under the expansion and contraction of the spring 107, the snap ring 106 moves horizontally on the T-shaped pillar 105 before it can be separated, which is not easy to cause the situation where the traditional buckle is separated from the clamping groove 110.

[0026] The circular groove 104, T-shaped pillar 105, snap ring 106, spring 107, L-shaped support rod 108, block 109 and slot 110 are arranged in two groups, which are symmetrically distributed on the vertical center plane of the support plate 103; that is, the components are arranged in two groups to enhance the safety of the buckle assembly when used. Even if one of the fasteners has a problem, the other can be used temporarily, and the damaged component can be repaired later.

[0027] like Figure 1 , 2 As shown, a connecting rod 201 is fixedly installed between the two L-shaped support rods 108 and connected to the inner wall at the corner of the L-shaped support rod 108. That is, the connecting rod 201 can facilitate the user to operate two sets of buckle components at the same time. The user holds the middle part of the connecting rod 201 and pulls the L-shaped support rod 108 outward to make the card block 109 fit inside the card slot 110.

[0028] like Figure 1 , 4As shown in Figures 5 and 6, a rotating rod 202 is also installed on the top of the base 101.

A through hole 205 is set on the support plate 103. The through hole 205 penetrates the upper and lower side walls of the support plate 103. When the support plate 103 is buckled, the center of the through hole 205 corresponds to the center of the rotating rod 202, that is, the rotating buckle 204 limits the opening and closing of the support plate 103. The rotating card plate 203 and the through hole 205 are correspondingly overlapped or cross-intersected, which can further limit the opening and closing of the support plate 103. A handle 206 is also installed on the top of the support plate 103 , that is, the handle 206 facilitates the opening and closing of the support plate 103 .

[0029] When using the safety buckle, one hand holds the handle 206 tightly and rotates the support plate 103 around the rotating shaft 102, and the other hand pulls the connecting rod 201 outward. Under the action of the T-shaped support 105, the retaining ring 106 and the spring 107, the L-shaped support rod 108 moves horizontally outward, and the blocking block 109 is aligned with the opening of the slot 110. The connecting rod 201 is released, and the spring 107 moves horizontally inward under the action of its own elastic force, and the blocking block 109 is connected to the inside of the slot 110.

[0030] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
