Description

Technical Field

[0001] This utility model relates to the field of relay technology, and in particular to a quick-installation structure for an armature assembly. Background Technology

[0002] In existing relays, the armature assembly is generally installed on the base by clamping. For example, in Chinese patent CN2013201292188, a high-current magnetic latching relay is provided on the base. After one pivot of the armature assembly is inserted into the shaft hole of the base, the fixing bracket is fixed to the base, so that the other pivot of the armature assembly is pivotally connected to the fixing bracket. This completes the installation of the armature assembly. Its structure is relatively complex, inconvenient to assemble, and costly.

[0003] Therefore, it is necessary to optimize the mounting structure of the armature assembly. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a quick installation structure for an armature assembly, which can realize the quick installation of the armature assembly, and has a simple structure and low cost.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A quick-installation structure for an armature assembly includes a base and an armature assembly. The base includes two oppositely arranged support walls, each of which is provided with a pivot groove extending through one end of the support wall. The armature assembly has two oppositely arranged rotating shafts, which are installed to the bottom of the pivot groove along the guiding direction of the pivot groove. A stop bar that can be elastically deformed by the pressure of the rotating shaft is also provided at the pivot groove. When the rotating shaft is installed to the bottom of the pivot groove, the stop bar returns to its original position and abuts against the circumference of the rotating shaft.

[0007] The quick-installation structure for the armature assembly provided by this utility model features an extended through-hole pivot groove and a stop bar at the pivot groove. During the installation of the rotating shaft into the pivot groove, the rotating shaft can elastically deform against the stop bar until it is installed to the bottom of the pivot groove. At this point, the rotating shaft disengages from the stop bar, and the stop bar resets and abuts against the circumferential direction of the rotating shaft, thereby restricting the rotating shaft to rotate at the bottom of the pivot groove. Thus, when installing the armature assembly, it is only necessary to press it into the pivot groove without any other steps, which can achieve quick installation of the armature assembly. The structure is simple and the cost is low.

[0008] Furthermore, the pivot groove includes a first section and a second section connected to each other. The first section is located near the end of the bearing wall, and the second section extends through the bearing wall along the axial direction of the pivot shaft. A stop bar is located inside the second section, with one end of the stop bar connected to the first section and the other end of the stop bar extending obliquely toward the bottom of the pivot groove.

[0009] Furthermore, gaps are maintained between the two sides of the baffle in the width direction and the two opposite sidewalls of the second section.

[0010] Furthermore, a guide surface is provided on the inner side of the first section.

[0011] Furthermore, the guiding surface is the first inclined surface.

[0012] Furthermore, the pivot groove is U-shaped, and the bottom of the pivot groove is arc-shaped.

[0013] Furthermore, the end edge of the rotating shaft is chamfered.

[0014] Furthermore, the end of the rotating shaft is provided with a second inclined surface, which is used to abut against the stop bar to resist the elastic deformation of the stop bar. Attached Figure Description

[0022] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] See Figures 1 to 5 This utility model discloses a quick-installation structure for an armature assembly. This structure is applied to a relay and aims to simplify the installation steps of the armature assembly and achieve quick installation.

[0026] In this embodiment, the structure includes a base 1 and an armature assembly 2. The armature assembly 2 has two opposing rotating shafts 21, and the armature assembly 2 is pivotally connected to the base 1 via the rotating shafts 21. Other structures of the armature assembly 2 can be any of the prior art. The innovation of this invention does not lie in other structures of the armature assembly 2, therefore, other structures of the armature assembly 2 are not specifically limited. For ease of understanding, as a specific example of the armature assembly 2, the armature assembly 2 may include a permanent magnet, a housing surrounding the permanent magnet, and two armatures respectively disposed at the two poles of the permanent magnet. A toggle block cooperating with a push card is disposed on one side of the housing, and the two rotating shafts 21 are respectively disposed on opposite sides of the housing.

[0027] In this embodiment, the base 1 includes two opposing support walls 11, which are used to mount the armature assembly 2. These two support walls 11 can be two transverse sidewalls of the mounting groove of the base 1, i.e., two sides of the rectangular enclosure of the mounting groove. The two sides of the two support walls 11 are connected by longitudinal sidewalls to form a mounting groove for mounting the electromagnet assembly; the two support walls 11 can also be independently extended. Each support wall 11 is provided with a pivot groove 12, which extends through to one end of the support wall 11 to... Figure 1 The direction shown is for reference only. Specifically, the lower end of the bearing wall 11 is fixed to the bottom plate of the base 1, the upper end of the bearing wall 11 extends upward, and the pivot groove 12 extends vertically through to the upper end of the bearing wall 11, so that the two rotating shafts 21 of the armature assembly 2 can move along the guiding direction of the pivot groove 12 (e.g., ...). Figure 1The two pivot grooves 12 are installed at the bottom of the two pivot grooves 12 respectively (from top to bottom). The pivot groove 12 is also provided with a stop bar 13 that can be elastically deformed by the pressure of the pivot 21. When the pivot 21 is installed at the bottom of the pivot groove 12, the stop bar 13 is reset and abuts against the circumference of the pivot 21. The pivot 21 can rotate at the bottom of the pivot groove 12, but it cannot be freely separated from the pivot groove 12 due to the resistance of the stop bar 13.

[0028] In the above scheme, by setting an extended through-hole pivot groove 12 and setting a stop bar 13 at the pivot groove 12, the pivot 21 can press against the stop bar 13 to elastically deform during the process of installing the pivot 21 into the pivot groove 12. Until the pivot 21 is installed to the bottom of the pivot groove 12, the pivot 21 disengages from the stop bar 13, and the stop bar 13 resets and abuts against the circumference of the pivot 21, thereby restricting the pivot 21 to rotate at the bottom of the pivot groove 12. In this way, when installing the armature assembly 2, it is only necessary to press it into the pivot groove 12 without any other steps, which can realize the quick installation of the armature assembly 2. Moreover, the structure is simple and the cost is low.

[0029] See Figures 2 to 4 In this embodiment, preferably, the pivot groove 12 includes a first section 121 and a second section 122 connected to each other. The first section 121 is located near the end of the bearing wall 11. Guide surfaces 1211 are respectively provided on the two opposite inner sides of the first section 121. The guide surfaces 1211 are preferably inclined first slopes. In the initial stage of installation, the two guide surfaces 1211 are respectively located in the circumferential direction of the rotating shaft 21. The guide surfaces 1211 are used to guide the insertion of the rotating shaft 21. The second section 122 penetrates the bearing wall 11 along the axial direction of the rotating shaft 21. The stop bar 13 is located in the second section. Within section 122, one end of the stop bar 13 is connected to the first section 121, and the other end of the stop bar 13 extends obliquely towards the bottom of the pivot groove 12. Specifically, one end of the stop bar 13 is connected to the lower side of the first section 121, and the inner side of the first section 121 and the oblique side of the stop bar 13 form a transition. When the rotating shaft 21 passes through the first section 121 and is installed into the second section 122, the end of the rotating shaft 21 can transition to abut against the oblique side of the stop bar 13, and as it continues to penetrate, it pushes the stop bar 13 to elastically deform until the rotating shaft 21 disengages from the stop bar 13. The second section 122, which penetrates the bearing wall 11 along the axial direction of the rotating shaft 21, facilitates the forming of the stop bar 13 on the bearing wall 11, making its production convenient and allowing it to be manufactured directly as a single piece using a mold.

[0030] See Figure 4In this embodiment, preferably, the end edge of the rotating shaft 21 is provided with a chamfer 211, and the end of the rotating shaft 21 is provided with a second inclined surface 212. Both the chamfer 211 and the second inclined surface 212 can be used to abut against the stop bar 13 to avoid generating chips. The chamfer 211 is preferably a rounded corner. Specifically, the inclination direction of the second inclined surface 212 is the same as or similar to the inclination direction of the stop bar 13. When the rotating shaft 21 enters the second section 122 from the first section 121, the chamfer 211 of the rotating shaft 21 first contacts the inclined side of the stop bar 13, and then transitions to the second inclined surface 212 of the rotating shaft 21 contacting the inclined side of the stop bar 13 to resist the elastic deformation of the stop bar. During the installation process, sharp scraping can be avoided in the contact area between the rotating shaft 21 and the stop bar 13, thereby avoiding the generation of chips.

[0031] See Figure 5 In this embodiment, preferably, there is a gap between both sides of the baffle 13 in the width direction and the two opposite sidewalls of the second section 122. The gap is preferably greater than 1mm. This gap has two functions: first, to avoid friction between the baffle 13 and the sidewall of the second section 122 when the baffle 13 is elastically deformed; second, when the armature assembly 2 needs to be disassembled, the baffle 13 can be elastically deformed by inserting a wire or iron wire into the lower end of the baffle 13, so that the baffle 13 no longer abuts against the circumference of the rotating shaft 21, thereby facilitating the removal of the rotating shaft 21.

[0032] In addition, to facilitate the sliding of the rotating shaft 21 before entering the bottom of the pivot groove 12, the two opposite sidewalls of the second section 122 are preferably inclined, and the distance between the two opposite sidewalls gradually decreases from top to bottom. In this way, during the elastic deformation of the rotating shaft 21 against the stop strip 13, the rotating shaft 21 is less likely to rub against the sidewall of the second section 122. Of course, it is also possible for only one sidewall of the second section 122 to be inclined.

[0033] See also Figure 5 Since the pivot 21 needs to rotate at the bottom of the pivot groove 12, in order to ensure a tight fit during rotation, preferably, the pivot groove 12 is U-shaped and the bottom of the pivot groove 12 is arc-shaped, and the arc-shaped bottom matches the diameter of the pivot 21.

[0034] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
