Description

Technical Field

[0001] This utility model relates to the field of aluminum profile splicing and assembly technology, and in particular to a quick-installation aluminum profile assembly. Background Technology

[0002] In automated production lines, aluminum profiles can be used to build equipment frames, material conveying tracks, etc.; in warehousing and logistics, they can be used to make shelves, stacker crane frames, etc., to meet the needs of goods storage and handling.

[0003] When using aluminum profiles to combine and form different products, it is generally necessary to assemble and install the aluminum profiles to form structures of new sizes and shapes. Currently, bolt and nut connections are generally used when assembling and installing aluminum profiles. That is, bolts and nuts are used to fasten the connecting parts of the aluminum profiles together. This connection method is relatively convenient.

[0004] For example, patent document CN201711309911.2 discloses a composite aluminum profile, the main structure of which includes a first aluminum profile and a second aluminum profile. The end of the first aluminum profile is fastened to a mounting plate by screws. Bolt holes are opened at the four corners of the outer wall of the mounting plate, and a through hole is opened in the middle of the outer wall of the mounting plate. A fastening bolt is provided in the inner cavity of the first aluminum profile. The end of the fastening bolt extends to the outside of the first aluminum profile through the through hole. A fixing plate is fixedly connected to the inner cavity of the second aluminum profile near the first aluminum profile. A threaded sleeve is vertically connected to the outer wall of the fixing plate. The second aluminum profile is cuboid. The four side walls of the second aluminum profile near the end of the first aluminum profile are provided with second mounting grooves. The fastening bolt is inserted into the inner cavity of the threaded sleeve and threaded and connected.

[0005] It can be seen that the combined aluminum profiles in the aforementioned existing technical documents are mainly connected by exposed fastening bolts and screws; however, the structural components of such bolted connections need to be exposed to the outside, which will affect the aesthetics and smoothness of the entire combined structure surface, and is not suitable for products with high surface precision requirements.

[0006] Based on this, this utility model designs a quick-assembly aluminum profile assembly that enables continuous and rapid assembly, in order to better solve the problems existing in the prior art. Utility Model Content

[0029] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-8 As shown in the image.

[0030] Example 1: A quick-install aluminum profile assembly includes two aluminum profiles 1 stacked from top to bottom. Two horizontally spaced snap-fit ​​strips 2 are inserted into the cavities at the mating surfaces of the two aluminum profiles 1. Each snap-fit ​​strip 2 is fixed to the corresponding aluminum profile 1 by elastic locking members 3 spaced along its length. Locking screws 5 are screwed into the through threaded holes 4 on both sides of each aluminum profile 1. Each locking screw 5 is used to push out the elastic locking member 3 it cooperates with and lock the snap-fit ​​strip 2 at the corresponding position.

[0031] In this design, the aluminum profile 1 is stacked and connected from top to bottom, which allows for adjustment of the size and width of the assembly. During actual installation, different numbers of aluminum profiles 1 can be selected and connected to each other as needed. Before installing the two aluminum profiles 1, the elastic locking parts 3 on each aluminum profile 1 need to be installed in place. After installation, the two aluminum profiles 1 are aligned. Then, the corresponding snap-fit ​​strips 2 are inserted into the space at each mating surface. After the snap-fit ​​strips 2 are in place, the two aluminum profiles 1 are kept in position. At this time, the locking screws 5 are screwed in sequentially. As the locking screws 5 are inserted, the rounded surface of their working end will act as a guide surface to directly push the corresponding elastic locking parts 3. When the elastic locking parts 3 are pushed by the inclined rounded surface, they will move outward along the radial direction of the through threaded hole 4. During the outward movement, the locking pins 303 at the outer ends of each elastic locking part 3 will quickly insert into the corresponding blind holes 201. When each blind hole 201 is in place, the snap-fit ​​strips 2 will be locked, thus locking each aluminum profile 1 and ensuring the firmness of the aluminum profile 1.

[0032] In any of the above embodiments, it is preferred that the aluminum profile 1 includes a profile body 101, a hollow main cavity 102 is provided at the center of the profile body 101, and through threaded holes 4 are respectively provided on the left and right sides of the hollow main cavity 102, which are arranged in the length direction of the aluminum profile 1. The inner side wall of the through threaded hole 4 is provided with internal threads, and side slots 103 are respectively provided on the upper part, lower part and one side of the outer side wall of the profile body 101 of each through threaded hole 4, which are arranged in the length direction of the profile body 101.

[0033] The aluminum profile 1 relies on the through threaded hole 4 as the space for installing the locking screw 5, and the two are screwed together. In addition, in order to save costs, a hollow main cavity 102 is set in the center of the aluminum profile 1, and a side slot 103 is set on its side to achieve the purpose of rapid weight reduction. At the same time, the side slot 103 can be used as a track when it is used as a conveyor.

[0034] In any of the above embodiments, it is preferred that the elastic locking member 3 includes mounting screw holes 301 disposed on the upper and lower parts of the through threaded hole 4, the two mounting screw holes 301 are respectively coaxially symmetrically arranged, the outer end of each mounting screw hole 301 is connected to the interior of the side slot 103 at its corresponding position, and an elastic locking pin is screwed into the interior of each mounting screw hole 301, the outer end of each elastic locking pin is respectively used to cooperate in the insertion blind hole 201 of the snap-fit ​​strip 2 at its corresponding position.

[0035] The entire elastic locking component 3 can be disassembled as a whole. During installation or disassembly, it is directly installed or disassembled by screwing on the external thread of the elastic locking pin. After installation, the outer end of the entire elastic locking pin is in a retracted state and does not extend into the side slots 103. After the locking screws 5 are installed, the outward abutment of the outer wall of the locking screw 5 will push the part that was originally protruding in the through threaded hole 4 outward. Since the outer end of the elastic locking pin in the original state is flush with the inner end face of the side slot 103, after being pushed, the elastic locking pins will protrude outward and extend into the insertion blind hole 201, thereby achieving quick locking.

[0036] In any of the above embodiments, preferably, the elastic locking pin includes a locking cylinder 302 threadedly installed in the mounting screw hole 301. An external thread that mates with the internal thread of the mounting screw hole 301 is provided on the outer wall of the locking cylinder 302. A locking pin 303 is fitted into the mounting cavity of the locking cylinder 302. The inner end of the locking pin 303 has a hemispherical portion 304. The locking pin 303 is positioned between the hemispherical portion 304 and the locking cylinder 302. A retaining spring 305 is fitted onto the outer side wall. One end of the retaining spring 305 is fixed to the inner end face of the locking cylinder 302, and the other end is fixed to the corresponding end face of the hemispherical part 304. The outer end of the locking pin 303 moves out of the center hole at the end of the mounting cavity and extends into the corresponding through threaded hole 4 to cooperate with the insertion blind hole 201 of the snap-fit ​​strip 2. The inner end of the hemispherical part 304 extends into the through threaded hole 4 and abuts against the outer side wall of the locking screw 5.

[0037] In any of the above embodiments, it is preferred that the snap-fit ​​strip 2 is supported by a plastic heat insulation strip, and a plurality of the insertion blind holes 201 are respectively provided on the corresponding outer side wall of the snap-fit ​​strip 2.

[0038] During installation, the elastic locking pin is locked in the mounting screw hole 301 by the locking cylinder 302. At this time, the locking cylinder 302 remains fixed, the outer end of the locking pin 303 is flush with the corresponding side wall of the side slot 103, and the clamping spring 305 is in its natural state. Then, as each locking screw 5 is installed, its end will be pushed inward as it is screwed deeper. During the pushing process, the curved surface of the hemispherical part 304 extending into the threaded hole 4 will be triggered. At this time, the hemispherical part 304 will move along the axial direction of the mounting screw hole 301, thereby compressing the clamping spring 305. Finally, the outer end of the locking pin 303 will be driven to extend outward and be inserted into the corresponding blind hole 201, thereby achieving quick locking.

[0039] The snap-fit ​​strip 2 installed here serves a dual purpose of connection and heat insulation.

[0040] Example 2: Compared with Example 1, this example also includes the following technical features:

[0041] In any of the above embodiments, it is preferred that the middle part of the snap-fit ​​strip 2 is a straight section 202, and the upper and lower sides of the straight section 202 are integrally formed with angular snap-fit ​​parts 203, which cooperate to clamp the side slots 103 at the corresponding positions.

[0042] The various angled snap-fit ​​parts 203 provided by the snap-fit ​​strip 2 can effectively clamp the side slot 103 in a timely manner, thus ensuring the stability of the aluminum profile 1 after it is connected by the snap-fit ​​strip 2.

[0043] In any of the above embodiments, it is preferred that each of the locking screws 5 has a chamfered curved surface 501 at its abutting end. The chamfered curved surface 501 can play a guiding role in the forward rotation and advance of the locking screw 5, and plays a guiding and pushing role when it abuts against the hemispherical part 304.

[0044] In any of the above embodiments, it is preferred that the number of elastic locking elements 3 installed at each of the through threaded holes 4 is N, where N≥2. Selecting an appropriate number of elastic locking elements 3 can reinforce the butt joints of aluminum profiles 1 of different lengths, effectively ensuring the stability of the connection.

[0045] Specific installation process: Before installing the two aluminum profiles 1, the elastic locking parts 3 on each aluminum profile 1 need to be installed in place. After installation, control the two aluminum profiles 1 to align. Then, insert the corresponding snap-fit ​​strips 2 into the space at each mating surface. After the snap-fit ​​strips 2 are in place, ensure that the two aluminum profiles 1 remain in position. At this time, screw in each locking screw 5 in sequence. As the locking screw 5 is inserted, the rounded surface of its working end will act as a guide surface to directly push the corresponding elastic locking part 3. When the elastic locking part 3 is pushed by the inclined rounded surface, it will move outward along the radial direction of the through threaded hole 4. During the outward movement, the locking pin 303 at the outer end of each elastic locking part 3 will quickly insert into the corresponding blind hole 201. When each blind hole 201 is in place, the snap-fit ​​strips 2 will be locked, thus locking each aluminum profile 1 and ensuring the firmness of the aluminum profile 1.

[0046] In summary, this quick-install aluminum profile assembly can rapidly stack and fix two adjacent aluminum profiles 1 as needed. During fixing, corresponding elastic locking components 3 and snap-fit ​​strips 2 can be pre-installed as required. Then, by screwing in the corresponding locking screws 5, the elastic locking components 3 are pushed and aligned with the snap-fit ​​strips 2, ensuring the quick-installation assembly of the two adjacent aluminum profiles 1 and the stability of the installed structure. After the two aluminum profiles 1 are joined, their connecting parts are all internally hidden, effectively concealing and maintaining the cleanliness and aesthetics of each aluminum profile 1's surface. When the edges of the aluminum profiles 1 are used as working surfaces, the assembled structure does not affect normal use. Each elastic locking component 3 adopts an elastic return structure. During disassembly, when the locking screws 5 are unscrewed, each elastic locking component 3 quickly returns to its original position, ensuring that disassembly only requires unscrewing the locking screws 5 to complete the quick disassembly of the assembly, improving the efficiency of disassembly and replacement.
