Description

TECHNICAL AREA

[0001] The present utility model relates to the technical field of profile assembly, in particular a profile connection assembly for easier quick assembly. STATE OF THE ART

[0002] Exhibition stands and light boxes are primarily used at various exhibitions. These stands and light boxes allow products to be displayed and presented to the public in a striking way, thereby increasing their advertising impact.

[0003] Currently, Chinese patent publication No. CN209691319U, published on November 26, 2019, discloses a spring-loaded fixed light box display comprising a frame and an LED light strip mounted on the inside of the frame. The frame includes a first profile, a second profile, a corner connector, and a snap connector. Two first profiles are provided and are located on the top and bottom of the frame. Four second profiles are provided and are arranged in pairs on the left and right sides of the frame. The corner connector is located at the junction between the first and second profiles, and the snap connector is located at the junction between two second profiles on the same side.The LED light strip is positioned on the inside of the second profile, and each of the first and second profiles has a slot extending along its length. One end of the corner connector is a fixed end that is firmly connected to the inside of the slot in the first profile, while the other end is a plug-in end that is inserted into the slot in the second profile. One end of the snap connector is a fixed end that is firmly connected to the inside of the slot in one of the second profiles, while the other end is a plug-in end that is inserted into the slot in the other of the second profiles.On a side of the first insertion end and the second insertion end facing the bottom of the insertion slot of the second profile, an installation groove is provided which extends along the longitudinal direction of the second profile, wherein a spring wire is arranged in the installation groove, the middle part of which extends in a wavy manner, and wherein an elastic projection is formed on the spring wire which protrudes from the installation groove and presses firmly against the bottom of the insertion slot.

[0004] When connecting the corners of the frame, the elastic projection on the spring wire presses firmly against the bottom of the insertion slot of the second profile after compression, in order to prevent the connection point between the first profile and the second profile and the connection point between two second profiles on the same side from loosening. This occurs when the first and second profiles are connected using the corner connector, and when the two second profiles on the same side are connected using the snap connector.

[0005] When the elastic projection on the spring wire presses firmly against the bottom of the insertion slot of the second profile, the elastic projection uses the frictional damping force for positioning. However, this positioning method using frictional damping force is unstable, so loosening can occur after frame assembly. CONTENTS OF THE PRESENT USE SAMPLE

[0006] The present utility model aims to provide a profile connection assembly for easier quick assembly, enabling convenient and stable profile mounting.

[0007] The above objective of the present utility model is achieved by the following technical solution: a profile connection assembly for facilitated quick assembly, comprising a connection base, an insertion arm arranged on the connection base, and a profile body positioned according to the insertion arm and whose end section is designed for the insertion of the insertion arm, wherein a positioning column is arranged on the insertion arm, and wherein a positioning hole is provided on the profile body through which the end section of the positioning column passes, and wherein an adjusting element is arranged in the insertion arm which adjusts the height of the positioning column in the vertical direction.

[0008] The present utility model is further designed such that the insertion arm comprises two side plates and two layer plates located between the two side plates, wherein the adjusting element comprises: a first through-hole provided on the two layer plates to allow the positioning column to pass through it, a connecting hole provided on the positioning column located between the two layer plates, and a first elastic rod that passes through the connecting hole and serves to elastically return the positioning column to its upward position.

[0009] The present utility model is further designed such that the first elastic rod comprises: a connecting section which passes through the connecting hole, and two pressure sections which are formed integrally on the end section of the connecting section, are bent downwards and inclined to press firmly against the side plates, and wherein a limiting section is arranged at an end of the connecting section facing away from the pressure section, which extends to the outside of the connecting hole and is inclined upwards.

[0010] The present utility model is further designed in such a way that a guide rail with an L-shaped cross-section is arranged on the inner wall of the profile body so that the side edge of the side plate can be embedded.

[0011] The present utility model is further designed such that a non-slip grooved surface is arranged on the upper end surface of the positioning column, wherein a guide ramp is arranged on the upper end surface of the positioning column on a side facing away from the connection base.

[0012] The present utility model is further designed such that an expanded groove is provided on each of two sides of the central part of the insertion arm, the adjusting element comprising: a second through-hole provided on the insertion arm to allow the positioning column to pass through it, a cavity section provided in the lower end of the positioning column, and a second elastic rod located on the underside of the cavity section, which serves to elastically return the positioning column to its upward position.

[0013] The present utility model is further designed such that the second elastic rod comprises: a rod seat located at the lower end of the positioning column, two extension sections which are connected at one end to the end section of the rod seat and extend inclined upwards into the cavity section, and a support section which is arranged at the upper end of the extension section and rests against the upper wall of the cavity section.

[0014] The present utility model is further designed such that the insertion arms are provided in a number of 2 and enclose an angle of 90 degrees with each other on a connecting base, with the two insertion arms each being inserted into the two profile bodies.

[0015] The present utility model is further designed such that the insertion arms are provided in a number of 2 and enclose an angle of 180 degrees with each other on a connecting base, with the two insertion arms each being inserted into the two profile bodies.

[0016] The present utility model is further designed such that the insertion arms are provided in a number of 2 and are arranged on the connection base in the direction of the X-axis and the Y-axis, wherein a vertical arm for insertion into the profile body is arranged in the direction of the Z-axis of the connection base, and wherein an open slot is provided on each of two sides of the upper end of the vertical arm in which an elastic arm is arranged, and wherein a clamping head is arranged on the end section of the elastic arm, and wherein a clamping hole is provided at a position on the profile body corresponding to the clamping head so that the clamping head can be embedded.

[0017] In summary, the present utility model has the following advantages: 1. During profile assembly, the insertion arm is inserted into the end section of the profile body. By adjusting the height of the positioning column upwards using the adjustment element, the upper end of the positioning column is guided through the positioning hole. The positioning column then secures the connection between the insertion arm and the profile body. When disassembling the profile, the height of the positioning column simply needs to be adjusted downwards, so that the upper end of the positioning column is pulled out of the positioning hole and the locking mechanism is released. This ultimately allows for convenient and stable profile assembly. 2. By pressing down on the positioning column, it moves downwards within the first through-hole. This movement can cause elastic deformation of the first elastic rod until the positioning column reaches the position of the positioning hole. The elastic restoring force of the first elastic rod can then cause the positioning column to spring back upwards and pass through the positioning hole, allowing for convenient vertical height adjustment of the positioning column. 3. As the positioning column moves downwards in the first through-hole, the two clamping sections bend downwards and tilt to press firmly against the side plate. This downward movement of the positioning column causes the connecting section to shift elastically downwards. When the positioning column is released, the connecting section springs upwards, pushing the positioning column upwards to reset it. Simultaneously, a limiting section is arranged at one end of the connecting section, opposite the clamping section. This limiting section extends outwards from the connecting hole and is inclined upwards. It serves to restrict movement and prevent the first elastic rod from disengaging from the positioning column. 4. When the insertion arm is inserted into the end section of the profile body, the guide rail attached to the inner wall of the profile body ensures the positioning of the inserted insertion arm. The guide rail has an L-shaped cross-section so that the side edge of the side plate can be embedded within it. 5. When the positioning column is pressed down, the non-slip grooved surface formed on its upper end face increases friction, thus facilitating stable downward pressure. A guide chamfer is arranged on the upper end face of the positioning column on the side facing away from the connection base. This guide chamfer provides a guiding function when the insertion arm is inserted into the end section of the profile body, enabling smooth embedding of the positioning column into the end section. 6. By pressing down on the positioning column, it moves downwards into the second through-hole. This movement can cause elastic deformation of the second elastic rod until the positioning column reaches the position of the positioning hole. The elastic restoring force of the second elastic rod can then cause the positioning column to spring back upwards and pass through the positioning hole, allowing for convenient vertical height adjustment of the positioning column. 7. When the positioning column moves downwards in the second through-hole, as the two extension sections extend inclined upwards into the cavity section and the support section rests against the upper wall of the cavity section, the downward-moving positioning column can cause the extension section to vibrate elastically through the support section, and after the positioning column is released, the extension section springs back upwards, after which the positioning column can be pushed upwards to reset. 8. Two insertion arms are provided and arranged along the X and Y axes on the connection base. Simultaneously, a vertical arm is arranged along the Z axis of the connection base for insertion into the profile body. This vertical arm can be inserted into the profile body in its vertical position. During insertion, the elastic arm is initially compressed, causing the clamping head to penetrate the profile body until it reaches the clamping hole. The elastic arm then retracts, driving the clamping head into the clamping hole and creating a snap-fit ​​connection between the vertical arm and the profile body in the vertical position.

[0019] The technical solutions in the exemplary embodiments are explained clearly and completely below. Obviously, the described exemplary embodiments do not represent all embodiments of the present utility model, but only a subset thereof. All other embodiments that a person skilled in the art in this field could obtain from the embodiments in the present utility model without any creative work should be considered to be covered by the scope of protection of the present utility model.

[0020] Exemplary embodiment 1: a profile connection assembly for simplified quick assembly, with reference to Fig. 1, Fig. 2 and Fig. 3 The profile connection assembly for facilitated quick assembly comprises a connection base 1, an insertion arm 2 arranged on the connection base 1 and a profile body 3 which is positioned according to the insertion arm 2 and whose end section is designed for the insertion of the insertion arm 2, wherein a positioning column 4 is arranged on the insertion arm 2, and wherein a positioning hole 31 is provided on the profile body 3 through which the end section of the positioning column 4 passes; and wherein a non-slip grooved surface 41 is arranged on the upper end face of the positioning column 4, while a guide ramp 42 is arranged on the upper end face of the positioning column 4 on a side facing away from the connection base 1.

[0021] With reference to Fig. 2, Fig. 3, Fig. 4 and Fig. The insertion arm 2 comprises two side plates 21 and two layer plates 22 located between the two side plates 21, wherein a guide rail 32 with an L-shaped cross-section is formed integrally on the inner wall of the profile body 3 so that the side edge of the side plate 21 can be embedded; and wherein an adjusting element 5 is further arranged in the insertion arm 2, which adjusts the height of the positioning column 4 in the vertical direction, wherein the adjusting element 5 comprises a first through-hole 51, a connecting hole 52 and a first elastic rod 53, and wherein the first through-hole 51 is provided in the two layer plates 22 so that the positioning column 4 can be guided through it, while the connecting hole 52 is provided on the positioning column 4 and is located between the two layer plates 22, and wherein the first elastic rod 53 is guided through the connecting hole 52 and serves toto elastically return the positioning column 4 upwards, wherein the first elastic rod 53 is made of spring steel, and wherein the first elastic rod 53 comprises: a connecting section 531 which passes through the connecting hole 52, and two pressure sections 532 which are formed integrally on the end section of the connecting section 531, are bent downwards and inclined to press firmly against the side plates 21, and wherein a limiting section 533 is arranged at an end of the connecting section 531 facing away from the pressure section 532, which extends to the outside of the connecting hole 52 and is inclined upwards.

[0022] Principle: During profile assembly, pressing down on the positioning column 4 causes elastic deformation of the first elastic rod 53. The insertion arm 2 is then inserted into the end section of the profile body 3 until the positioning column 4 moves into its position within the positioning hole 31. When the positioning column 4 is released, the first elastic rod 53 returns to its original shape, thereby driving the positioning column 4 upwards so that its upper end is guided through the positioning hole 31. The positioning column 4 then secures the connection between the insertion arm 2 and the profile body 3. When disassembling the profile, the positioning column 4 only needs to be pressed down again so that its upper end is pulled out of the positioning hole 31 and the connection is released.This ultimately allows for convenient and stable profile mounting.

[0023] Exemplary embodiment 2: a profile connection assembly for simplified quick assembly, with reference to Fig. 6, Fig. 7, Fig. 8 and Fig. 9 The difference to embodiment 1 lies in the insertion arm 2 and the adjusting element 5, wherein an expanded groove 201 is provided on each of two sides of the central part of the insertion arm 2, and wherein the adjusting element 5 comprises: a second through-hole 501 provided on the insertion arm 2 to allow the positioning column 4 to pass through, a cavity section 502 provided in the lower end of the positioning column 4, and a second elastic rod 503 located on the underside of the cavity section 502, which serves to elastically return the positioning column 4 to its upward position, while the second elastic rod 503 is also made of spring steel, wherein the second elastic rod 503 comprises: a rod seat 5031 located at the lower end of the positioning column 4, two extension sections 5032,which are integrally connected at one end to the end section of the rod seat 5031 and extend inclined upwards into the cavity section 502, and a support section 5033 which is integrally arranged at the upper end of the extension section 5032 and rests against the upper wall of the cavity section 502, and wherein the rod seat 5031 is supported on the inner wall of the widened groove 201.

[0024] With reference to Fig. 6 the insertion arms 2 are provided in a number of 2 and arranged in the direction of the X-axis and the Y-axis on the connection base 1, wherein in the direction of the Z-axis of the connection base 1 a vertical arm 6 is arranged for insertion into the profile body 3, and wherein on two sides of the upper end of the vertical arm 6 an open slot 61 is provided in which an elastic arm 62 is arranged, and wherein a clamping head 621 is arranged at the end section of the elastic arm 62, and wherein a clamping hole 301 is provided at a position of the profile body 3 corresponding to the clamping head 621 so that the clamping head 621 can be embedded.

[0025] Principle: By pressing down on the positioning column 4, it moves downwards in the second through-hole 501. Since the two extension sections 5032 extend upwards at an angle into the cavity section 502, and the support section 5033 rests against the upper wall of the cavity section 502, the downwardly moving positioning column 4 can cause the extension section 5032 to vibrate elastically via the support section 5033. As soon as the positioning column 4 reaches the positioning hole 31, the extension section 5032 springs back upwards after the positioning column 4 is released. The positioning column 4 can then be pushed upwards to reset itself. During this upward rebound, the positioning column 4 passes through the positioning hole 31, thus enabling convenient height adjustment of the positioning column 4.

[0026] Exemplary embodiment 3: a profile connection assembly for simplified quick assembly, with reference to Fig. 10 The difference to embodiment 1 lies in the fact that the insertion arms 2 are provided in a number of 2 and enclose an angle of 90 degrees with each other on a connection base 1, whereby the two insertion arms can each be inserted into the two profile bodies 3.

[0027] Exemplary embodiment 4: a profile connection assembly for simplified quick assembly, with reference to Fig. 11 The difference to embodiment 1 lies in the fact that the insertion arms 2 are provided in a number of 2 and enclose an angle of 180 degrees with each other on a connection base 1, whereby the two insertion arms 2 can each be inserted into the two profile bodies 3.
