Description

Technical Field

[0001] The present application relates to the technical field of connection structures, and more particularly to a connection piece and a safe containing the same. Background Art

[0002] When a product with a multi-component assembly structure needs to be connected, a connector needs to be set between the two components to be connected to achieve the connection; currently, the connector is generally divided into two components, one of which is inserted into the socket of the component to be connected, and the other component is inserted into the component, so that the component expands and thus achieves a tight fit between the sockets of the component. Although this method can achieve the connection between the two components, it is more difficult to disassemble. An external prying tool needs to be inserted into the gap between the two components, and then the upper component is pried to separate it from the lower component. The connector of this structure is time-consuming and labor-intensive to disassemble, and the prying tool is also prone to damage the components, resulting in the disassembled components being unable to be used again. Utility Model Content

[0003] In response to the above-mentioned deficiencies in the prior art, the present application provides a connector that is easy to disassemble, saves time and effort, and is not likely to cause damage to components.

[0004] In order to solve the above technical problems, the technical solution adopted in this application is: a connecting member, the structure of which includes a first connecting member and a second connecting member; the first connecting member is used to be plugged into the connecting hole of the component to be connected, and the second connecting member is used to be plugged into the first connecting member, and to make the first connecting member expand and fit tightly with the connecting hole; the second connecting member is connected to a force-applying part, and the force-applying part is used to apply force to drive the second connecting member to disengage from the first connecting member.

[0005] With the above structure, when the connecting piece of the present application is used to connect components, the first connecting piece can be first inserted into the connecting hole of the component to be connected, and then the second connecting piece can be inserted into the first connecting piece so that the first connecting piece expands and fits tightly with the inner wall of the connecting hole to achieve a tight fit, so that the two components to be connected are connected to each other; and when disassembling, the operator only needs to apply force directly to the force-applying part of the second connecting piece to drive the second connecting piece to separate from the first connecting piece. Therefore, this connecting piece structure with a force-applying part does not require the use of an external prying tool to pry the second connecting piece, nor does it require the prying tool to be inserted into the gap between the first connecting piece and the second connecting piece. Therefore, it will not cause damage to the connecting piece, and the operation is more time-saving and labor-saving.

[0006] Furthermore, the first connecting member includes a support plate, and a claw that can be opened and closed extends from one end face of the support plate; the second connecting member includes a chuck, and an expansion member extends from one end face of the chuck, and the expansion member is used to be inserted into the claw, so that the claw expands and is fastened to the connecting hole of the component to be connected; with this structure, when connecting, the expansion member of the second connecting member is directly inserted into the claw that can be opened and closed of the first connecting member, so that the claw is expanded to achieve a tight fit with the connecting hole, and the connection is convenient.

[0007] Furthermore, the chuck includes a fixed part and a rotating part, and the rotating part can be rotated and pulled up relative to the fixed part to form the force-applying part; with this structure, when the second connecting part needs to be removed from the claw, the rotating part of the chuck can be rotated and pulled up relative to the fixed part, thereby forming a pull ring structure that is easy to operate, and the second connecting part can be more conveniently removed from the claw by pulling the pull ring.

[0008] Furthermore, a slot is provided on the support plate, a trigger is horizontally provided in the slot, one end of the trigger forms the force-applying part, a through-hole is provided on the trigger for inserting the stretching piece, after the stretching piece is inserted into the claw from the through-hole, the chuck is located on the upper surface of the trigger; with the above structure, after the trigger is placed in the slot, the stretching piece is then inserted into the claw from the through-hole, and the claw is stretched to realize the fastening connection of the components; and when disassembly is required, one end of the trigger can be directly pried, the trigger is lifted and the chuck is lifted at the same time, and the chuck can drive the stretching piece to be pulled out from the claw, thereby realizing the disassembly action.

[0009] Furthermore, one end of the trigger extending laterally is configured to be L-shaped, and the vertical portion of the L-shaped structure extends downward. With this structure, when the trigger is bent to lift it up, the L-shaped structure will abut against the edge of the support plate to form a support point, making it more convenient and labor-saving to lift the trigger.

[0010] Furthermore, the middle part of the trigger is circular, and the outer edge of the circular middle part is adapted to the accommodating space formed by the slot on the support plate; with this structure, the trigger can be placed in the slot and form a firm fit with the slot, without displacement that affects the insertion of the expansion piece.

[0011] Furthermore, there are four claws, which are evenly distributed along the circumference, and gaps are provided between adjacent claws. The four claws surround each other to form a space for the support member to be inserted. With this structure, the expansion and resetting of the claws can be facilitated, and the expanded state forms a more balanced fit and fastening with the inner wall of the component connection hole.

[0012] Furthermore, the bottom end of the expansion member is provided with a conical surface, and the outer wall of the expansion member is extended with a ridge; with this structure, the conical bottom end is more conducive to the expansion member entering the claw, and the setting of the ridge can realize the expansion support of the claw.

[0013] Furthermore, there are four ridges, and the support plate is provided with a socket for the expansion piece to be inserted. The socket is connected to the gap provided between adjacent claws, and the ridges are inserted into the gaps from the sockets. With this structure, after the expansion piece is inserted into the claw, its four ridges are respectively inserted into the corresponding four gaps, which is more conducive to the stability of the position of the expansion piece and to achieve continuous expansion of the claws.

[0014] The present application also provides a safe, which contains the connecting piece described above in the present application. Through this connecting piece, the components in the safe can be firmly connected without the need for screwing. Assembly and disassembly are also faster and more convenient, and the requirements for operating space are low. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As attached Figure 1-10As shown, a connector of the present application, the structure of the connector includes a first connector 1 and a second connector 2; the first connector 1 is used to be plugged into the connecting hole 301 of the component 3 to be connected, and the second connector 2 is used to be plugged into the first connector 1, and the first connector 1 is expanded to fit tightly with the connecting hole 301; the second connector 2 is connected to a force-applying part a, and the force-applying part a is used to apply force to drive the second connector 2 to disengage from the first connector 1; that is, the present application divides the connector into two first connectors 1 and second connectors 2 that can be plugged in and separated from each other, and the first connector is expanded to fit tightly with the connecting hole 301 by plugging, thereby realizing the connection between the two components; and the second connector is also connected to the force-applying part a, and when disassembling, the second connector 2 can be directly separated from the first connector 1 by applying force through the force-applying part a.

[0030] With the above structure, when the connecting piece of the present application is used to connect components, the first connecting piece can be first inserted into the connecting hole of the component to be connected, and then the second connecting piece can be inserted into the first connecting piece so that the first connecting piece expands and fits tightly with the inner wall of the connecting hole to achieve a tight fit, so that the two components to be connected are connected to each other; and when disassembling, the operator only needs to directly pull the force-applying part of the second connecting piece to drive the second connecting piece to separate from the first connecting piece. Therefore, this connecting piece structure with a force-applying part does not require the use of an external prying tool to pry the second connecting piece, nor does it require the prying tool to be inserted into the gap between the first connecting piece and the second connecting piece. Therefore, it will not cause damage to the connecting piece, and the operation is more time-saving and labor-saving.

[0031] As attached Figure 1-10As shown, as an example, the first connecting member 1 described in the present application includes a support plate 101, and a claw 102 that can be opened and closed is extended from one end surface of the support plate 101; the second connecting member 2 includes a chuck 201, and an expansion member 202 is extended from one end surface of the chuck 201. The expansion member 202 is used to be inserted into the claw 102, so that the claw 102 is expanded to be fastened with the connecting hole 301 of the component 3 to be connected; specifically, when the support plate 101 is in use, the end surface of the claw 102 is in contact with the component 3 to be connected, and the chuck 201 is in contact with the support plate 101; a plurality of claws 102 are provided, and the plurality of claws 102 are mutually embraced to form a space for the expansion member 202 to be inserted. After the expansion member 202 is inserted, the plurality of claws 102 are expanded outward, thereby achieving a tight fit between the claws 102 and the component 3 to be connected, and at the same time, the second connecting member 2 is also tightly fitted with the first connecting member 1 through the expansion member 202; with this structure, when connecting, the expansion member of the second connecting member is directly inserted into the opening and closing claws of the first connecting member, thereby expanding the claws to achieve a tight fit with the connecting hole, and the connection is convenient.

[0032] Example 1

[0033] As attached Figure 1-8 As shown, the chuck 201 described in this application includes a fixed portion 203 and a rotating portion 204. The rotating portion 204 can be rotated and pulled up relative to the fixed portion 203 to form the force-applying portion a (see the attached FIG. Figure 7 In this structure, the stretching member 202 is provided on the fixing portion 203 and extends along the axial direction of the fixing portion 203. With this structure, when the second connecting member 2 needs to be pulled out from the claw 102, the rotating portion 204 of the chuck 201 can be rotated and pulled up relative to the fixing portion 203, thereby forming a pull ring structure that is convenient for operation, namely the force applying portion a (see the attached figure for details). Figure 3 The second connecting member 2 can be more conveniently removed from the claw 102 by pulling the pull ring; and the fixed portion 203 and the rotating portion 204 form a complete chuck 201. When disassembly is required, the rotating portion 204 is rotated and pulled up. When disassembly is not required, the rotating portion 204 is laid flat to form a flat chuck, which does not require additional space and does not affect the loading of the product.

[0034] As attached Figure 6As shown, the rotating part 204 described in the present application is provided with a symmetrically arranged rotating shaft 205 (the two rotating shafts are symmetrically arranged and extend inwardly toward each other), and the corresponding fixed part 203 is provided with an axial hole 206, and the rotating shaft 205 is rotatably fitted into the axial hole 206; specifically, the connection position of the rotating shaft and the axial hole is located in the center position of the chuck or more toward the side of the fixed part; with this structure, the connection stability between the rotating part 204 and the fixed part 203 is improved by symmetrically arranging the rotating shaft 205 and the axial hole 206, and at the same time, a more balanced pulling force can be achieved, which is conducive to extracting the second connecting member 2 from the claw 102.

[0035] As attached Figure 6 As shown, the upper surface of the chuck 201 described in the present application is a frustum; with this structure, a more rounded end face is presented, which will not cause damage to the operator.

[0036] Example 2

[0037] As attached Figure 9-10 As shown, the support disk 101 described in the present application is provided with a card slot 103 (specifically, the card slot 103 can be formed by a plurality of axial protrusions provided on the end surface of the support disk 101), and a trigger 4 is transversely provided in the card slot 103 (the trigger can be a long strip of plate structure, the extension length of one end of which protrudes from the outside of the support disk to facilitate force application), and one end of the trigger 4 forms the force application portion a (specifically, refer to Figure 9 ), the trigger 4 is provided with a through-hole 401 for the expansion member 202 to be inserted, the expansion member 202 is inserted into the claw 102 from the through-hole 401, and the chuck 201 is located on the upper surface of the trigger 4; with the above structure, the trigger 4 is placed in the slot 103 and the position of the trigger 4 is fixed by the slot, and then the expansion member 202 is inserted into the claw 102 from the through-hole 401, and the claw 102 is expanded to achieve a fastening connection with the component; and when disassembly is required, one end of the trigger 4 can be directly pried, the trigger 4 is lifted to form a prying tool and the chuck 201 is lifted at the same time, and the chuck 201 can drive the expansion member 202 to be pulled out from the claw 102, and the disassembly action can be achieved.

[0038] As attached Figure 9 、 Figure 10 As shown, the trigger 4 described in the present application is provided with an L-shaped structure at one end extending laterally, and the vertical portion 402 of the L-shaped structure extends downward, that is, extends toward the plug-in end of the support member 202; with this structure, when the trigger 4 is bent to lift it up, the L-shaped structure will abut against the edge of the support plate 101 to form a support point, thereby making it more convenient and labor-saving to lift the trigger 4; and the L-shaped structure can also form a stop between the outer wall of the support plate 101, so that the trigger 4 is accurately positioned radially.

[0039] As attached Figure 9-10 As shown, the middle portion 403 of the trigger 4 described in the present application is circular, and the outer edge of the circular middle portion 403 is adapted to the accommodating space formed by the slot 103 on the support plate 101 (for details, please refer to the attached Figure 10 With this structure, the trigger 4 can be placed in the slot 103 and form a stable fit with the slot 103 without displacement affecting the insertion of the stretching member 202.

[0040] Specifically, as attached Figure 2 and Figure 5 As shown, as an example, the present application provides four claws 102, and the four claws 102 are evenly distributed along the circumference, and a gap 5 is provided between the adjacent claws 102 (that is, the adjacent claws are not in direct contact, and a certain distance is left between each other), and the four claws 102 are surrounded by each other to form a space for the support member 202 to be plugged in; adopting this structure, the expansion and resetting of the claws can be facilitated, and the expanded state forms a more balanced fit and fastening with the inner wall of the component connection hole; specifically, the outer diameter of the support member 202 is larger than the inner diameter of the plug-in space formed by the four claws 102, and only after insertion can the four claws 102 be expanded, thereby tightly fitting with the connection hole 301 of the component 3; the plug-in space formed by the four claws 102 also has a bottom, which can abut against the front end face of the support member 202, that is, the plug-in end, to avoid the transition plug-in crossing the lower end of the claw 102 and causing difficulty in pulling out and resetting the support member.

[0041] Specifically, as attached Figure 1-2 and Figure 3 、 Figure 7 As shown, as an example, the bottom end of the support member 202 described in the present application is provided with a conical surface 207, and the outer wall of the support member 202 is extended with a ridge 208 (the ridge 208 extends along the length direction of the support member and extends to the conical surface); with this structure, the conical bottom end is more conducive to the support member entering the claw, and the setting of the ridge can realize the expansion support of the claw.

[0042] Specifically, as attached Figure 2 、 4 As shown, as an example, the present application provides four ridges 208, and the support plate 101 is provided with a socket 104 for the expansion member 202 to be inserted into, the socket 104 is communicated with the gap 5 provided between the adjacent claws 102, and the ridge 208 is inserted into the gap 5 from the socket 104; with this structure, after the expansion member 202 is inserted into the claw 102, its four ridges 208 are respectively inserted into the corresponding four gaps 5, thereby making it more conducive to stabilizing the position of the expansion member 202, so as to achieve continuous expansion and pushing of the claw 102.

[0043] As attached Figure 11 As shown, the present application also provides a safe, which contains the connecting piece described above in the present application. Through this connecting piece, the components in the safe can be firmly connected without the need for screwing, and assembly and disassembly are also faster and more convenient, with low requirements for operating space.

[0044] The specific working principle and process of the connectors of the two embodiments of the present application are as follows: the connector in embodiment 1, first, the first connector 1 is inserted into the connecting hole 301 of component 3 (component 3 can be a partition structure located in the safe, and an L support member for supporting the partition, the partition and the L support member are both provided with connecting holes 301, and the connecting holes 301 of the two are aligned), the support plate 101 of the first connector 1 is in contact with the end face of the upper component 3, and then the second connector 2 is inserted from the socket 104 on the first connector 1 into the space formed by the plurality of claws 102, so that The plurality of claws 102 expand to each other and thus fit tightly with the inner wall of the connecting hole 301, thereby connecting the two parts 3 to each other. At this time, the second connecting member 2 is also tightly fitted in the first connecting member 1 and cannot fall off. When disassembly is required, the rotating part 204 of the chuck 201 is rotated and pulled up relative to the fixed part 203 to form a pull ring, that is, the force-applying part a, and the second connecting member 2 is pulled upward to separate from the first connecting member 1. The claws 102 automatically retract without the expansion force of the propping part 202, thereby separating the parts 3. For the connecting part of the second embodiment, first insert the first connecting member 1 into the connecting hole 301 of the part 3, and then 103 of the first connecting member 1, align the through-hole 401 on the trigger 4 with the insertion hole 104 on the first connecting member 1 for inserting the stretching member 202, and finally insert the stretching member 202 of the second connecting member 2 through the through-hole 401 of the trigger 4 into the insertion space formed by the multiple claws 102. After being inserted to the bottom, the multiple claws 102 are expanded and tightly fit with the inner wall of the connecting hole 301, so that the second connecting member 2 cannot fall off automatically, thereby achieving the function of fixing the two components 3; when disassembly is required, bend one end of the trigger 4 upwards (one end of the trigger 4 radially protrudes outside the support plate 101 to form a The force-applying portion a is provided for easy operation), and the trigger 4 now forms a prying tool, which pushes the chuck 201 of the second connecting member 2 upward to lift it up, thereby removing the second connecting member 2 from the claw 102, and the two connected parts 3 are loosened and separated; therefore, the structure of the connecting member of the present application, since the force-applying portion for easy force application is directly provided on the connecting member, does not require the aid of an external prying tool during disassembly, but directly pulls or pries the trigger to separate the second connecting member from the first connection, which saves time and effort, and will not cause damage to the connecting member. It can be reused many times after disassembly.
