Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of riding drawer accessories, and in particular to a positioning protrusion flattening device. Background Technology

[0002] Currently, various connection structures exist on the market between the drawer arm and the drawer panel. These connection structures generally include a front bracket installed on the drawer panel, a fixing bracket installed on the drawer arm, and an adjustment bracket installed on the fixing bracket. For example, Chinese Utility Model Patent Application No. 201720343073.X discloses a "Connecting Device for Connecting Drawer Arm and Drawer Panel," in which an insert bracket 100 of the panel connecting mechanism is inserted into an insert cavity groove. A locking pin on the insert bracket 100 engages with a locking component of an elastic buckle assembly. Through a sleeve design on the locking pin, when the drawer panel is pulled, the sleeve on the insert bracket 100 contacts the locking component, and the sleeve rotates a certain position following the rotation of the locking component. A fixing component 200 is connected to one end of the insert bracket 100 to facilitate panel connection.

[0003] like Figure 1 and 2 The diagram shows the assembly between the insert holder 100 and the fastener 200. Generally, the fastener 200 has two protrusions 300 at the mounting positions of the insert holder 100, and corresponding mounting holes are provided at the corresponding positions on the insert holder 100. The mounting holes are installed on the protrusions 300 to achieve positioning of the insert holder 100 and the fastener 200 before fixed connection. The two protrusions 300 corresponding to the two mounting holes ensure force balance between the insert holder 100 and the fastener 200. After the insert holder 100 and the fastener 200 are positioned, the protrusions 300 need to be flattened to prevent the insert holder 100 from detaching from the fastener 200. However, current flattening processes are all done manually, resulting in low assembly efficiency. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides a positioning protrusion flattening device to solve the above problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a positioning protrusion flattening device, including a support base, a mounting base, a linear drive assembly, an upper hinge arm assembly and a lower hinge arm assembly;

[0006] The linear drive assembly is disposed on the support base, and the output end of the linear drive assembly is simultaneously hinged to the first end of the upper hinge arm assembly and the first end of the lower hinge arm assembly.

[0007] The mounting base is simultaneously hinged to the second end of the upper hinge arm assembly and the second end of the lower hinge arm assembly. Both the upper hinge arm assembly and the lower hinge arm assembly are provided with teeth. When the linear drive assembly makes a linear movement, the second ends of the upper hinge arm assembly and the second ends of the lower hinge arm assembly rotate around the mounting base, thereby causing the teeth located on the upper hinge arm assembly and the teeth located on the lower hinge arm assembly to move closer to or further away from each other.

[0008] Preferably, the linear drive assembly includes a cylinder and a support member. The cylinder body is connected to the mounting base, and the telescopic shaft of the cylinder is connected to the support member.

[0009] Optionally, the support includes a base and hinge ears. The base has two hinge ears on both sides. The base is connected to the telescopic shaft of the cylinder. The first end of the upper hinge arm assembly and the first end of the lower hinge arm assembly are disposed between the two hinge ears. The hinge ears, the first end of the upper hinge arm assembly, and the first end of the lower hinge arm assembly are connected by a hinge shaft so that the first end of the upper hinge arm assembly and the first end of the lower hinge arm assembly can rotate about the hinge shaft.

[0010] It is worth noting that both sides of the mounting base are provided with cover plates, and the cover plates have guide grooves extending from the mounting base to the support base. The end of the hinge shaft extends into the guide groove and is slidably connected to the guide groove.

[0011] Specifically, the upper hinge arm assembly includes a first stop arm, an upper pressure arm, and an upper punch. The first end of the first stop arm is hinged to the support member, the second end of the first stop arm is hinged to the first end of the upper pressure arm, the second end of the upper pressure arm is hinged to the support seat, the upper pressure arm is provided with an upper punch, and the end of the upper punch is provided with the protruding tooth.

[0012] The lower hinge arm assembly includes a second stop arm, a lower pressure arm, and a lower punch. The first end of the second stop arm is hinged to the support member, the second end of the second stop arm is hinged to the first end of the lower pressure arm, the second end of the lower pressure arm is hinged to the support seat, the lower pressure arm is provided with a lower punch, and the end of the lower punch is provided with the protruding tooth.

[0013] Preferably, the support base is provided with an upper hinge hole and a lower hinge hole arranged vertically. The through hole at the second end of the upper pressure arm is aligned with the upper hinge hole and then hinged through the upper connecting shaft. The through hole at the second end of the lower pressure arm is aligned with the lower hinge hole and then hinged through the lower connecting shaft.

[0014] The beneficial effects of this invention are as follows: In the positioning protrusion flattening device, after the insert bracket is set on the fixing component, the position with the protrusion is placed between the protrusions of the upper hinge arm assembly and the lower hinge arm assembly, and located on the movement trajectory of the protrusions; by simultaneously driving the upper and lower hinge arm assemblies with the linear drive assembly, the protrusions of the upper and lower hinge arm assemblies are brought closer to each other, thus flattening the protrusions through the protrusions, thereby fixing the insert bracket and the fixing component. Compared to manual operation, this linear drive assembly improves assembly efficiency. Attached Figure Description

It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1-8 As shown, a positioning protrusion flattening device includes a mounting base 1, a support base 2, a linear drive assembly 3, an upper hinge arm assembly 4, and a lower hinge arm assembly 5.

[0026] The linear drive assembly 3, the upper hinge arm assembly 4, and the lower hinge arm assembly 5 are disposed between the mounting base 1 and the support base 2, wherein the linear drive assembly 3 is disposed on the support base 2, and the output end of the linear drive assembly 3 is simultaneously hinged to the first end of the upper hinge arm assembly 4 and the first end of the lower hinge arm assembly 5.

[0027] The mounting base 1 is simultaneously hinged to the second end of the upper hinge arm assembly 4 and the second end of the lower hinge arm assembly 5. Both the upper hinge arm assembly 4 and the lower hinge arm assembly 5 are provided with protruding teeth 44. When the linear drive assembly 3 performs linear motion, the second ends of the upper hinge arm assembly 4 and the lower hinge arm assembly 5 rotate around the mounting base 1, thereby causing the protruding teeth 44 located on the upper hinge arm assembly 4 and the protruding teeth 44 located on the lower hinge arm assembly 5 to move closer to or further away from each other.

[0028] like Figure 3-7 As shown, in the positioning protrusion flattening device, after the insert holder 100 is set on the fixing member 200, the position with the protrusion 300 is placed between the protrusion 44 of the upper hinge arm assembly 4 and the protrusion 44 of the lower hinge arm assembly 5, and located on the movement trajectory of the protrusion 44; by simultaneously driving the upper hinge arm assembly 4 and the lower hinge arm assembly 5 through the linear drive component 3, the protrusion 44 of the upper hinge arm assembly 4 and the protrusion 44 of the lower hinge arm assembly 5 are brought closer to each other, so that the protrusion 300 is flattened by the protrusion 44, thereby fixing the insert holder 100 and the fixing member 200. Compared with manual operation, the assembly efficiency can be improved by driving with such a linear drive component 3.

[0029] It is worth noting that, such as Figure 3 and 6As shown, the linear drive assembly 3 includes a cylinder 31 and a support member 32. The cylinder body of the cylinder 31 is connected to the mounting base 1, and the telescopic shaft of the cylinder 31 is connected to the support member 32.

The telescopic shaft of the cylinder 31 can drive the support member 32 to move back and forth. In conjunction with the hinge structure between the first end of the upper hinge arm assembly 4 and the first end of the lower hinge arm assembly 5 and the support member 32, the second end of the upper hinge arm assembly 4 and the second end of the lower hinge arm assembly 5 can be opened and closed, thereby causing the protrusion 44 located on the upper hinge arm assembly 4 and the protrusion 44 located on the lower hinge arm assembly 5 to move away from or towards each other.

[0030] Specifically, such as Figure 6 As shown, the support member 32 includes a base 321 and hinge ears 322. The base 321 has two hinge ears 322 on both sides. The base 321 is connected to the telescopic shaft of the cylinder 31. The first end of the upper hinge arm assembly 4 and the first end of the lower hinge arm assembly 5 are disposed between the two hinge ears 322. The hinge ears 322, the first end of the upper hinge arm assembly 4, and the first end of the lower hinge arm assembly 5 are connected by a hinge shaft 33, allowing the first ends of the upper hinge arm assembly 4 and the lower hinge arm assembly 5 to rotate around the hinge shaft 33. By providing hinge ears 322, the first ends of the upper hinge arm assembly 4 and the lower hinge arm assembly 5 can be easily hinged to it.

[0031] Specifically, such as Figure 6 and 8 As shown, both sides of the mounting base 1 are provided with cover plates 6. The cover plates 6 have guide grooves 61 extending from the mounting base 1 towards the support base 2. The end of the hinge shaft 33 extends into the guide groove 61 and is slidably connected to the guide groove 61. The cover plates 6 are provided on the left and right sides of the mounting base 1 and can protect the cylinder 31. Through the cooperation of the guide groove 61 and the hinge shaft 33, the support member 32 can only move in the back-and-forth direction. With the structure that the first end of the upper hinge arm assembly 4 and the first end of the lower hinge arm assembly 5 are hinged to it, the second end of the upper hinge arm assembly 4 and the second end of the lower hinge arm assembly 5 can be opened and closed.

[0032] Preferred, such as Figure 3 As shown, the upper hinged arm assembly 4 includes a first stop arm 41, an upper pressure arm 42, and an upper punch 43. The first end of the first stop arm 41 is hinged to the support member 32, the second end of the first stop arm 41 is hinged to the first end of the upper pressure arm 42, the second end of the upper pressure arm 42 is hinged to the support seat 2, the upper pressure arm 42 is provided with an upper punch 43, and the end of the upper punch 43 is provided with the protruding tooth 44.

[0033] The lower hinge arm assembly 5 includes a second stop arm 51, a lower pressure arm 52, and a lower punch 53. The first end of the second stop arm 51 is hinged to the support member 32, the second end of the second stop arm 51 is hinged to the first end of the lower pressure arm 52, the second end of the lower pressure arm 52 is hinged to the support seat 2, the lower pressure arm 52 is provided with a lower punch 53, and the end of the lower punch 53 is provided with the protruding tooth 44.

[0034] The lever structure is formed by the first stop arm 41 and the upper pressure arm 42, and the lever structure is formed by the second stop arm 51 and the lower pressure arm 52, thereby realizing the opening and closing of the upper pressure arm 42 and the lower pressure arm 52, and then driving the corresponding protrusion 44 to move through the upper punch 43 and the lower punch 53.

[0035] In this embodiment, in order to ensure the stability of the connection between the insert holder 100 and the fixing member 200, two protrusions 300 are provided at the position where the insert holder 100 is installed on the fixing member 200. When flattening, the two protrusions 300 also need to be flattened at the same time. Therefore, the end of the upper punch 43 and the end of the lower punch 53 are provided with two protruding teeth 44. These two protruding teeth 44 correspond one-to-one with the protrusions 300. In this way, when the protruding teeth 44 at the end of the upper punch 43 and the protruding teeth 44 at the end of the lower punch 53 approach each other, the two protrusions 300 can be flattened at the same time.

[0036] It is worth noting that, such as Figure 3 As shown, the support base 2 has an upper hinge hole and a lower hinge hole arranged vertically. The through hole at the second end of the upper pressure arm 42 is aligned with the upper hinge hole and then hinged via the upper connecting shaft 11. The through hole at the second end of the lower pressure arm 52 is aligned with the lower hinge hole and then hinged via the lower connecting shaft 12. By setting the upper connecting shaft 11 and the lower connecting shaft 12, the second ends of the upper pressure arm 42 and the lower pressure arm 52 are hinged to the support base 2.

[0037] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments without departing from the principles and spirit of this utility model will still fall within the protection scope of this utility model.
