Description

Technical Field

[0001] This invention relates to the field of assembled exhibition equipment, and in particular to a connection module for assembled exhibition equipment. Background Technology

[0002] The existing frame boxes, brackets or other support structures mostly use threaded connections by directly tapping or threading the connecting end of the connecting pipe (equivalent to the shell in this application). In this installation method, the screws need to match the length of the connecting pipe. When the length of the connecting pipe is too long, it will be difficult to guarantee the accuracy between the screw and the assembly fixture. In addition, the axial installation of the connecting pipe requires a certain amount of space in the axial direction of the connecting pipe for the screwdriver to rotate, which puts certain requirements on the installation site.

[0003] In the Chinese patent application number 202310841860.7 entitled "A Connection Module and Modular Assembly Display Equipment", the output shaft is driven to rotate and be installed by a 90° reversal between the active bevel gear and the driven bevel gear. In the above solution, the active bevel gear and the driven bevel gear cooperate to reverse the direction.

[0004] In summary, how to provide an alternative implementation method for installing the connection module has become an urgent problem for researchers in this field. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to implement the installation of the connection module;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] This invention is a connection module for assembling an exhibition fixture, comprising: a housing having a radial first channel and a second channel communicating with and perpendicular to the first channel; an input section rotatably disposed at the first channel; an output shaft rotatably disposed at the second channel, one end of which extends out of the housing and is configured as a connection section for connecting with the exhibition fixture to be assembled; and a plurality of L-shaped connecting shafts, each having its first end inserted into a first hole at the bottom of the input section and its second end inserted into a second hole at the end of the output shaft.

[0008] In this design, the housing has a first channel and a second channel arranged perpendicularly to each other. The input part is rotatably disposed in the first channel, and the output shaft is rotatably disposed in the second channel. One end of the output shaft with a connecting part can pass through the housing. The input part and the output shaft are connected by a rotating L-shaped connecting shaft, with both ends of the L-shaped connecting shaft placed in the first hole of the input part and the second hole of the input part, respectively.

[0009] When the connection module needs to be installed, the end of the output shaft with the connecting part is abutted against the display fixture, and the output shaft and the mounting hole of the display fixture to be assembled are in a coaxial state. The input part is rotated by the tool, and the output shaft is rotated by the transmission of the L-shaped connecting shaft. The output shaft is screwed into the mounting hole to realize the connection between the rotating housing and the display fixture.

[0010] It should be noted that the connecting part can adopt a threaded structure or an eccentric wheel and nut structure to fix the shell to the exhibit to be assembled.

[0011] To accommodate the installation of the connecting module within a small space, this invention employs a limiting groove located at the second channel; a rotating disk rotatably positioned at the limiting groove, through which multiple L-shaped connecting shafts pass; and an elastic element, one end of which abuts against the rotating disk, and the other end of which abuts against the end of the output shaft.

[0012] The rotating disk is positioned within the limiting groove of the second channel, allowing the L-shaped connecting shaft to pass through. An elastic element is positioned between the rotating disk and the output shaft. When installing a connecting module in a small space, such as an installation space of 20cm in length and a housing axial length of 20cm, the length of the connecting module would exceed 20cm because the end of the output shaft would protrude from the housing, making installation in a small space impossible. In this connecting module, the above-mentioned solution is used to compress the output shaft within the housing, causing the elastic element to contract under pressure within the housing. When the output shaft is aligned with the mounting hole, rotating the input part releases the elastic element, providing a certain axial force to the output shaft, and screwing the connecting part into the mounting hole, thus enabling the installation of the connecting module in a small space.

[0013] To limit the maximum rotation distance of the output shaft, the present invention employs a first stepped surface at the output shaft; and a second stepped surface that abuts against the first stepped surface is provided in the second channel;

[0014] In this design, the first and second step surfaces separate under elastic compression. During installation, the output shaft moves axially to bring the first and second step surfaces together. At this point, the output shaft rotates to its limit position, limiting the maximum rotation distance of the output shaft.

[0015] To illustrate that the input section only rotates within the first channel, the present invention employs a second limiting groove provided within the first channel; the outer wall of the input section is provided with a limiting ring that rotatably engages with the second limiting groove;

[0016] The limiting ring is rotatably set in the second limiting groove, so that the input part only rotates within the first channel.

[0017] To facilitate the installation of the output shaft, input section, L-shaped connecting shaft, and rotating disk, the present invention employs a housing comprising: a fixing section; and an insertion section adapted to be axially inserted into the fixing section and forming the first channel and the second channel with the fixing section.

[0018] In this design, the housing is a split unit, consisting of a fixing part and an insertion part. The insertion part can be axially inserted into the fixing part. When the fixing part and the insertion part are separated, the first channel and the second channel are open. The output shaft can be axially inserted into the second channel, and one end of the L-shaped connecting shaft can be axially inserted into the second hole. The first hole of the input part is radially inserted into the L-shaped connecting shaft. The fixing part and the insertion part are then joined together to achieve the installation of the output shaft, the input part, the L-shaped connecting shaft, and the rotating disk.

[0019] In order to achieve the installation of the insertion part and the fixing part after insertion, the present invention adopts a fixed connection between the insertion part and the fixing part by a limiting pin;

[0020] When the limiting pin is inserted between the insertion part and the fixing part after they are engaged, a fixed connection between the insertion part and the fixing part is achieved.

[0021] To illustrate how the insertion part is axially inserted into the fixing part, the present invention employs guide members on both sides of the insertion part; and guide grooves that cooperate with the guide members are provided on the inner walls of both sides of the fixing part.

[0022] The guide and guide groove work together to ensure that the insertion part always moves in a straight line when it is inserted into the fixing part.

[0023] To achieve the rotation of the output section, the present invention employs a groove at the end of the input section to drive its rotation.

[0024] In this design, the tool and the groove work together. When the tool rotates, it causes the input part to rotate. The groove in this design is a regular hexagonal hole.

[0025] In order to achieve pre-fitting between the shell and the display fixture, the present invention adopts a fitting part at the end of the shell; the inner side of the fitting part is connected to the shell by a positioning pin, and its outer side is set as the fitting surface to fit the display fixture to be assembled.

[0026] In this design, the display fixture is a columnar structure, and the bonding surface is bonded to the surface of the display fixture, so that the shell is pre-fitted to the display fixture through the bonding part.

[0027] The beneficial effects of this invention are as follows: This invention is a connecting module for assembling exhibition equipment. When the connecting module needs to be installed, one end of the housing is abutted against the exhibition equipment, and the output shaft and the mounting hole are in a coaxial state. The elastic element is compressed and retracted in the housing. The input part is rotated by the tool, and the output shaft and the rotating disk are rotated by the transmission of the L-shaped connecting shaft. At this time, the elastic element releases its elastic force, giving the output shaft a certain axial force, and screwing the output shaft into the mounting hole to realize the connection between the rotating housing and the exhibition equipment.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0036] like Figure 1-5 As shown, the present invention is a connection module for assembling an exhibition fixture, comprising: a housing 1 having a radially arranged first channel 11 and a second channel 12 communicating with and perpendicularly arranged to the first channel 11; an input part 2 rotatably disposed at the first channel 11; an output shaft 3 rotatably disposed at the second channel 12, one end of which extends out of the housing 1 and is configured as a connection part for connecting with the exhibition fixture to be assembled; and a plurality of L-shaped connecting shafts 4, the first ends of which are all inserted into a first hole 21 at the bottom of the input part 2, and the second ends of which are all inserted into a second hole 31 at the end of the output shaft 3;

[0037] In this design, the housing has a first channel and a second channel arranged perpendicularly to each other. The input part is rotatably disposed in the first channel, and the output shaft is rotatably disposed in the second channel. One end of the output shaft with a connecting part can pass through the housing. The input part and the output shaft are connected by a rotating L-shaped connecting shaft, with both ends of the L-shaped connecting shaft placed in the first hole of the input part and the second hole of the input part, respectively.

[0038] When the connection module needs to be installed, the end of the output shaft with the connecting part is abutted against the display fixture, and the output shaft and the mounting hole of the display fixture to be assembled are in a coaxial state. The input part is rotated by the tool, and the output shaft is rotated by the transmission of the L-shaped connecting shaft. The output shaft is screwed into the mounting hole to realize the connection between the rotating housing and the display fixture.

[0039] It should be noted that the connecting part can adopt a threaded structure or an eccentric wheel and nut structure to fix the shell to the exhibit to be assembled.

[0040] To accommodate the installation of the connection module within a small space, this invention employs a limiting groove 13, which is located at the second channel 12; a rotating disk 5, which is rotatably positioned at the limiting groove 13 and allows multiple L-shaped connecting shafts 4 to pass through; and an elastic member 6, one end of which abuts against the rotating disk 5 and the other end of which abuts against the end of the output shaft 3.

[0041] The rotating disk is positioned within the limiting groove of the second channel, allowing the L-shaped connecting shaft to pass through. An elastic element is positioned between the rotating disk and the output shaft. When installing a connecting module in a small space, such as an installation space of 20cm in length and a housing axial length of 20cm, the length of the connecting module would exceed 20cm because the end of the output shaft would protrude from the housing, making installation in a small space impossible. In this connecting module, the above-mentioned solution is used to compress the output shaft within the housing, causing the elastic element to contract under pressure within the housing. When the output shaft is aligned with the mounting hole, rotating the input part releases the elastic element, providing a certain axial force to the output shaft, and screwing the connecting part into the mounting hole, thus enabling the installation of the connecting module in a small space.

[0042] In some embodiments, such as Figure 3 , 5 As shown, in order to limit the maximum rotation distance of the output shaft, the present invention employs a first stepped surface 32 at the output shaft 3; and a second stepped surface 14 that abuts against the first stepped surface 32 is provided in the second channel 12.

[0043] In this design, the first and second step surfaces separate under elastic compression. During installation, the output shaft moves axially to bring the first and second step surfaces together. At this point, the output shaft rotates to its limit position, limiting the maximum rotation distance of the output shaft.

[0044] In some embodiments, such as Figure 3 , 4 As shown in Figure 5, in order to illustrate that the input part only rotates within the first channel, the present invention employs a second limiting groove 15 provided within the first channel 11; the outer wall of the input part 2 is provided with a limiting ring 22 that rotatably engages with the second limiting groove 15;

[0045] The limiting ring is rotatably set in the second limiting groove, so that the input part only rotates within the first channel.

[0046] In some embodiments, such as Figure 5 As shown, in order to facilitate the installation of the output shaft, input section, L-shaped connecting shaft, and rotating disk, the present invention adopts a housing comprising: a fixing part 16; and an insertion part 17, which is adapted to be axially inserted into the fixing part 17 and forms the first channel 11 and the second channel 12 with the fixing part 17.

[0047] In this design, the housing is a split unit, consisting of a fixing part and an insertion part. The insertion part can be axially inserted into the fixing part. When the fixing part and the insertion part are separated, the first channel and the second channel are open. The output shaft can be axially inserted into the second channel, and one end of the L-shaped connecting shaft can be axially inserted into the second hole. The first hole of the input part is radially inserted into the L-shaped connecting shaft. The fixing part and the insertion part are then joined together to achieve the installation of the output shaft, the input part, the L-shaped connecting shaft, and the rotating disk.

[0048] In some embodiments, such as Figure 3 , 4 As shown, in order to achieve the installation of the insertion part and the fixing part after insertion, the present invention adopts a fixed connection between the insertion part 16 and the fixing part 17 by a limiting pin 18.

[0049] When the limiting pin is inserted between the insertion part and the fixing part after they are engaged, a fixed connection between the insertion part and the fixing part is achieved.

[0050] In some embodiments, such as Figure 3 , 4 As shown, in order to illustrate how the insertion part is axially inserted into the fixing part, the present invention provides guide members 19 on both sides of the insertion part 17; and guide grooves 110 that cooperate with the guide members 19 are provided on the inner walls of both sides of the fixing part 16.

[0051] The guide and guide groove work together to ensure that the insertion part always moves in a straight line when it is inserted into the fixing part.

[0052] In some embodiments, such as Figure 3 , 4 As shown, to achieve the rotation of the output section, the present invention uses a groove 23 at the end of the input section 2 to drive it to rotate.

[0053] In this solution, the tool and the slot work together. When the tool rotates, it drives the input part to rotate. The slot in this solution is set as a regular hexagonal hole. Of course, the slot can also be set as a straight slot or a cross slot structure.

[0054] In some embodiments, such as Figure 1 , 2 As shown in Figures 3 and 4, in order to achieve pre-fitting between the shell and the display fixture, the present invention provides a fitting part 7 at the end of the shell; the inner side of the fitting part 7 is connected to the shell 1 by a positioning pin 71, and its outer side is set as a fitting surface 72 for fitting the display fixture to be assembled.

[0055] In this design, the display fixture is a columnar structure with an arc-shaped bonding surface. The bonding surface is attached to the surface of the display fixture, allowing the shell to be pre-fitted to the display fixture through the bonding part.

[0056] The bonding surface needs to be bonded to the surface of the exhibition equipment to be assembled for pre-positioning.

[0057] The connection module in this solution can be used not only for exhibition equipment, but also for furniture, display stands, etc.

[0058] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
