Description

Technical Field

[0001] This utility model relates to the field of electromechanical component installation technology, and in particular to a quick-positioning electromechanical component snap-fit ​​connection device. Background Technology

[0002] The quick-positioning electromechanical component snap-fit ​​connection device is a mechanical connection component used in the field of electromechanical equipment assembly. It achieves quick positioning, precise docking, and convenient disassembly and assembly between electromechanical components through a snap-fit ​​structure. The core of it is to integrate the self-locking characteristics of mechanical snap-fit ​​with the guiding and limiting function of the positioning structure, which solves the problems of low assembly efficiency, difficult disassembly and maintenance, and poor positioning accuracy of traditional bolt connection and welding methods.

[0003] The existing technology has the following problems: Many latches rely on elastic structures for locking, such as elastic claws and cantilever latches. However, under prolonged cyclic loads or frequent disassembly and assembly, stress concentration areas like the base are prone to fatigue damage. This is especially true for latches made of plastics like ABS; if the base radius is too small, brittleness will worsen at low temperatures, making them extremely prone to breakage. Once a latch breaks, it cannot be repaired, potentially rendering the entire associated component unusable. Different materials have significantly different coefficients of thermal expansion; in extreme high or low temperature environments, the latch and mating components are susceptible to gaps or stress cracking due to thermal expansion and contraction. Utility Model Content

[0004] This invention provides a quick-positioning electromechanical component snap-fit ​​connection device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A quick-positioning electromechanical component snap-fit ​​connection device includes a base, nuts threaded to both sides of the top of the base, suction cups fixedly installed on both sides of the bottom of the base, a rectangular groove formed on the top of the base, a positioning snap-fit ​​mechanism provided on the top of the rectangular groove, and a heat-conducting tight-fitting mechanism provided on the top of the base. The positioning and fastening mechanism includes a central disc, which is fixedly installed on the top of the base.

[0006] Preferably, the positioning and fastening mechanism further includes a stepper motor, which is fixedly installed at the center of the inner wall of the base. The drive end of the stepper motor is fixedly connected to a rotating shaft, and a transmission disc is fixedly connected to the outer wall of the rotating shaft.

[0007] Preferably, a plurality of arc-shaped holes are evenly provided in the middle of the circumference of the transmission disc, and a sleeve rod is slidably connected to the inner wall of each arc-shaped hole, and a right-angle plate is fixedly connected to the top of each sleeve rod.

[0008] Preferably, a plurality of rectangular cavities are evenly distributed around the center of the central disk, the outer wall of the right-angle plate is slidably connected to the inner wall of the rectangular cavity, and a plurality of limiting grooves are evenly distributed around the bottom of the central disk, the outer wall of the sleeve is slidably connected to the inner wall of the limiting groove.

[0009] Preferably, an arc-shaped plate is fixedly connected to the end of the right-angle plate away from the sleeve rod, and multiple rubber columns are uniformly fixedly connected to the inner wall of the arc-shaped plate.

[0010] Preferably, the heat-conducting tight-fitting mechanism includes multiple heating wires, which are uniformly and fixedly connected inside the central disk, and multiple heat-conducting holes are opened on the top of the central disk.

[0011] Preferably, the top of the arc-shaped plate is hinged with a fastener, and the bottom two sides of the fastener are fixedly connected with connecting springs. The ends of the connecting springs away from the fasteners are fixedly connected to the arc-shaped plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a quick-positioning electromechanical component snap-fit ​​connection device. A stepper motor drives a transmission disc to rotate, and the arc-shaped hole on the transmission disc drives a sleeve rod to move along an arc-shaped trajectory, thereby achieving the expansion and contraction adjustment of the right-angle plate. Combined with the rectangular cavity for the right-angle plate and the limiting groove for the sleeve rod's trajectory, the device ensures the consistency of movement of each component during adjustment. It can adapt to cylindrical electromechanical components with different outer diameters. When the arc-shaped plate at the end of the right-angle plate is attached to the outer wall of the component, the rubber column on its inner wall increases the friction with the component through elastic deformation, preventing slippage. Furthermore, the snap-fit ​​component further clamps the outer wall of the component with the elastic tension of the connecting spring, forming a multi-level snap-fit ​​structure with arc-shaped plate attachment, rubber column anti-slip, and snap-fit ​​component elastic clamping.

[0013] 2. This utility model provides a quick-positioning electromechanical component snap-fit ​​connection device. Heat is evenly transferred to the central disc and the arc-shaped plate through heat-conducting holes. In low-temperature environments, it can preheat plastic and rubber connectors, restoring their elasticity and toughness. This avoids problems such as cracking and loose fit during snap-fit ​​due to the low-temperature brittleness of the material. The uniform distribution design of the heat-conducting holes ensures that heat can be simultaneously transferred to each arc-shaped plate, ensuring consistent preheating temperature for all connectors and preventing material aging caused by localized overheating. It also ensures uniform fit between each arc-shaped plate and the component, preventing loosening due to stiffness in localized connectors, and improving the stability and reliability of the connection under low-temperature conditions.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 - Figure 6 As shown, a quick-positioning electromechanical component snap-fit ​​connection device includes a base 1, nuts 2 are threadedly connected to both sides of the top of the base 1, suction cups 3 are fixedly installed on both sides of the bottom of the base 1, a rectangular groove is opened on the top of the base 1, a positioning snap-fit ​​mechanism is provided on the top of the rectangular groove, and a heat-conducting tight-fitting mechanism is provided on the top of the base 1. The positioning and fastening mechanism includes a central plate 41, which is fixedly installed on the top of the base 1.

[0018] It should be noted that the electromechanical components to be connected are installed together with the base 1 and the overall structure by means of nuts 2 on both sides, and the two sets of suction cups 3 are used to make the assembly of the electromechanical components more secure.

[0019] like Figure 3 , Figure 5 As shown, the positioning and fastening mechanism also includes a stepper motor 42, which is fixedly installed at the center of the inner wall of the base 1. The drive end of the stepper motor 42 is fixedly connected to a rotating shaft 43, and the outer wall of the rotating shaft 43 is fixedly connected to a transmission disk 44.

[0020] It should be noted that the stepper motor 42 drives the rotating shaft 43 to rotate, which in turn drives the transmission disk 44 to rotate at the bottom of the central disk 41.

[0021] like Figure 3 As shown, a number of arc-shaped holes 45 are evenly opened in the middle of the circumference of the transmission disc 44. The inner wall of each arc-shaped hole 45 is slidably connected to a sleeve rod 46, and the top of each sleeve rod 46 is fixedly connected to a right-angle plate 47.

[0022] It should be noted that as the transmission disc 44 rotates, the sleeve 46 on the inner wall of each arc hole 45 can move along the arc trajectory with the cooperation of each arc hole 45, thereby driving each right-angle plate 47 to expand or contract for adjustment.

[0023] like Figure 4 - Figure 5 As shown, a number of rectangular cavities 49 are evenly distributed around the center of the central disk 41. The outer wall of the right-angle plate 47 is slidably connected to the inner wall of the rectangular cavity 49. A number of limiting grooves 48 are evenly distributed around the bottom of the central disk 41. The outer wall of the sleeve rod 46 is slidably connected to the inner wall of the limiting groove 48.

[0024] It should be noted that with the rectangular cavity 49 in place, each right-angle plate 47 can be adjusted along a defined trajectory to avoid deviation from a single movement path. At the same time, the limiting groove 48 can also limit the movement trajectory of the sleeve rod 46 to ensure the consistency of the overall adjustment.

[0025] like Figure 3 As shown, the right-angle plate 47 is fixedly connected to an arc-shaped plate 410 at the end away from the sleeve rod 46, and multiple rubber columns 411 are evenly fixedly connected to the inner wall of the arc-shaped plate 410.

[0026] It should be noted that as each right-angle plate 47 expands or contracts, the shape of the component to be connected can be adapted and adjusted, so that the inner wall of each arc plate 410 is attached to the outer wall of the component, and with the cooperation of each rubber column 411, the snap-fit ​​effect is more secure.

[0027] like Figure 4 , Figure 5 As shown, the heat-conducting and close-fitting mechanism includes multiple heating wires 51, which are uniformly and fixedly connected inside the central disk 41. Multiple heat-conducting holes 52 are opened on the top of the central disk 41.

[0028] It should be noted that during the snap-fit ​​connection of electromechanical components, the heating wire 51 can operate for a period of time in advance, and distribute the heat evenly to the central plate 41 and each arc plate 410 through the heat conduction hole 52. When the ambient temperature is low, it can preheat and soften each connector, avoiding poor connection effect and detachment in a stiff state.

[0029] like Figure 6As shown, the top of the arc plate 410 is hinged with a fastener 53, and the bottom two sides of the fastener 53 are fixedly connected with connecting springs 54. The ends of the connecting springs 54 away from the fastener 53 are fixedly connected to the arc plate 410.

[0030] It should be noted that, based on the contact between each arc plate 410 and the outer wall of the electromechanical component, each fastener 53 can be further moved to cause each set of connecting springs 54 to deform, thereby forming an elastic tension that allows each fastener 53 to be snapped onto the outer wall of the electromechanical component, ensuring the firmness of the snap-fit ​​connection.

[0031] The working principle of this utility model: First, the electromechanical components to be connected are installed together with the base 1 and the overall structure using the nuts 2 on both sides, and then two sets of suction cups 3 are used to ensure the sturdiness of the electromechanical components assembly. The stepper motor 42 drives the rotating shaft 43 to rotate, which in turn drives the transmission disk 44 to rotate at the bottom of the central disk 41. As the transmission disk 44 rotates, the sleeve 46 on the inner wall of the arc-shaped hole 45 can move along the arc-shaped trajectory with the cooperation of each arc-shaped hole 45, thereby driving each right-angle plate 47 to expand or contract. With the rectangular cavity 49 set, each right-angle plate 47 can be adjusted along the limited trajectory to avoid the situation of single movement path deviation. At the same time, the limiting groove 48 can also limit the movement trajectory of the sleeve 46 to ensure the consistency of the overall adjustment. As each right-angle plate 47 expands or contracts, the shape of the connecting parts can be adapted and adjusted, so that the inner wall of each arc plate 410 adheres to the outer wall of the part, and with the cooperation of each rubber column 411, the snap-fit ​​effect is more secure. During the snap-fit ​​connection of the electromechanical parts, the heating wire 51 can operate for a period of time in advance, and the heat is evenly distributed to the central plate 41 and each arc plate 410 through the heat conduction hole 52. When the ambient temperature is low, the connecting parts can be preheated and softened to avoid poor connection effect and detachment in a stiff state. Based on the contact between each arc plate 410 and the outer wall of the electromechanical component, each fastener 53 can be further moved to deform each set of connecting springs 54, thereby forming an elastic tension that allows each fastener 53 to be snapped onto the outer wall of the electromechanical component, ensuring the firmness of the snap-fit ​​connection.
