Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a monotonous arm with an arm cover. Background Technology

[0002] As the name suggests, a glass cabinet is a cabinet made of glass. Glass cabinets are widely used in shopping malls or exhibition venues to display products. A glass cabinet is mainly used as a counter to store items.

[0003] Currently, the arm covers used on monohedrons are all connected by snap-fit. Snap-fit ​​has the drawback of being easy to install but difficult to remove. Although this method can increase installation stability, it can easily lead to damage to the snap-fit ​​during disassembly. This is because it is related to factors such as the quality of the snap-fit ​​material, the load-bearing capacity of the design, and the magnitude of the external force. If the snap-fit ​​material itself is not strong enough, it is easy to break when subjected to large tensile, compressive, or shear forces. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing a monotonous arm with an arm cover to solve the aforementioned problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This monotonous arm with an arm cover includes a monotonous arm body. The frame connecting section of the monotonous arm body is hollowed out to form an inner cavity. A first partition plate is provided in the inner cavity so that the frame connecting section forms two assembly stations. A positioning plate is provided between the first partition plate and the frame connecting section. An arm cover is provided between the positioning plate and the first partition plate to cover one of the assembly stations. A locking component that can be retracted under pressure is provided in the arm cover. The locking component enters into the inner cavity when the arm cover is closed at the assembly station, and allows the locking component to retract to the width of the inner cavity after entering by using the pressure force, so as to achieve a tight transition fit.

[0006] Further improvements include an outer shell and several first reinforcing ribs disposed within the outer shell. The first reinforcing ribs enter the inner cavity when the outer shell is closed at the assembly station, and a locking component perpendicular to the extending direction of the first reinforcing ribs is provided at their lower ends.

[0007] Further improvements include the provision of several second reinforcing ribs within the inner cavity that act simultaneously on the first partition plate. When the first reinforcing ribs enter the inner cavity, the second reinforcing ribs abut against the locking assembly, generating a squeezing force that causes some of the first reinforcing ribs to bend outward through the abutment.

[0008] Further improvements include a locking assembly comprising a sleeve, an abutment, and a spring. The sleeve is located at the lower end of the first reinforcing rib and has a second partition plate inside that divides the interior into two assembly cavities. First inserts are provided on both sides of the second partition plate. Second inserts are provided on the inner side of the abutment. One end of the spring is inserted into the second insert and the other end is inserted into the first insert. When subjected to compressive force, the spring causes the abutment to move inward to adapt to the width of the inner cavity.

[0009] Further improvements include a rounded corner transition on the outer circumference of the joint.

[0010] To further improve the design, a guide sleeve is provided on the inner side of the abutment, located outside the second insertion post and arranged in a ring. The outer circumferential surface of the guide sleeve fits against the inner circumferential surface of the assembly cavity.

[0011] The beneficial effects of this utility model are:

[0012] The arm cover and inner cavity of this utility model achieve quick and convenient assembly through a transition fit. The transition fit is achieved by a locking component that can be retracted under pressure. The retraction of the locking component occurs when it enters the inner cavity, and the entry method is only a straight insertion, which also facilitates subsequent disassembly.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] Referring to the attached diagram: This type of monolithic arm with an arm cover includes a monolithic arm body 1. The frame connecting section of the monolithic arm body 1 is hollowed out to form an inner cavity 2. A first partition plate 3 is provided in the inner cavity 2, which allows the frame connecting section to form two assembly stations. A positioning plate 4 is provided between the first partition plate 3 and the frame connecting section. An arm cover 5 is provided between the positioning plate 4 and the first partition plate 3 to cover one of the assembly stations. A locking component 6 that can be retracted under pressure is provided in the arm cover 5. The locking component 6 enters into the inner cavity 2 when the arm cover 5 is closed at the assembly station, and after entering, the locking component 6 can be retracted to the width of the inner cavity 2 by the pressure force to achieve a tight transition fit. The principle of this utility model is that the arm cover 5 is a decorative item and is set when only a storage frame is installed on the monochromatic arm body 1. The monochromatic arm body 1 with only a storage frame is set at the sidemost position of the cabinet. At this time, one side of the monochromatic arm body 1 is transparent glass, so there is no space to install the storage frame. Therefore, setting the arm cover 5 can increase the aesthetics. The first partition plate 3 is used to divide the inner cavity 2 into two. The positioning plate 4 and the first partition plate 3 form side positioning and end positioning. In this way, the installation position can be quickly determined when installing the storage frame or the arm cover 5. The locking component 6 is used to ensure the stability of the arm cover 5 covering the monochromatic arm body 1 and also simplifies the assembly method. That is, after entering, it will retract by squeezing. After retraction, it will adapt to the width of the inner cavity 2. The transition fit method not only meets the assembly stability but also facilitates subsequent disassembly.

[0019] The arm cover 5 includes an outer shell 51 and a number of first reinforcing ribs 52 disposed inside the outer shell 51. The first reinforcing ribs 52 enter the inner cavity 2 when the outer shell 51 is closed at the assembly station, and a locking component 6 is provided at its lower end perpendicular to the extension direction of the first reinforcing rib 52. This arrangement increases the structural strength of the arm cover 5 and can be connected to the locking component 6. When the arm cover 5 is closed on the monotonous arm body 1, the locking component 6 can enter the inner cavity 2 simultaneously and achieve a transition fit.

[0020] The inner cavity 2 is provided with several second reinforcing ribs 21 that act simultaneously on the first partition plate 3. When the first reinforcing rib 52 enters the inner cavity 2, the second reinforcing ribs 21 abut against the locking component 6, and the abutment generates a squeezing force that causes part of the first reinforcing rib 52 to bend outward. This arrangement can further increase the closing stability of the arm cover 5. That is, the width of the second reinforcing rib 21 gradually increases from top to bottom, while the distance between the first reinforcing rib 52 and the locking component 6 and the second reinforcing rib 21 gradually decreases. In order to adapt to the width change of the second reinforcing rib 21, the first reinforcing rib 52 will bend, which is achieved by the squeezing force generated by the second reinforcing rib 21. Moreover, the entire arm cover 5 is injection molded as a whole, so after the bending change, a self-resetting resistance force is generated, which is then converted into a clamping force, thereby increasing the closing stability.

[0021] The locking assembly 6 includes a sleeve 61, an abutment 62, and a spring 63. The sleeve 61 is located at the lower end of the first reinforcing rib 52 and has a second partition plate 6111 inside, which divides the interior into two assembly cavities 611. First insertion posts 61111 are provided on both sides of the second partition plate 6111. A second insertion post 621 is provided on the inner side of the abutment 62. One end of the spring 63 is inserted into the second insertion post 621, and the other end is inserted into the first insertion post 61111. When subjected to compressive force, the spring 63 drives the abutment 62 to move inward to adapt to the width of the inner cavity 2. The sleeve 61 provides assembly... The space and activity space are formed by the second partition plate 6111, which makes the interior of the locking component 6 have the ability to deform under pressure and retract. The second partition plate 6111 is also used to set the first insert 61111, and the abutment 62 is provided with the second insert 621. The spring 63 is inserted and cooperates with the two inserts. In this way, when the abutment 62 enters the inner cavity 2, when it is squeezed, the spring 63 will automatically compress and retract. After compression and retraction, it will generate self-resetting elasticity. The elasticity is also a resistance force, which is then converted into clamping force to increase the stability of the cover.

[0022] The outer circumferential surface of the abutment 62 is provided with a rounded transition 622. When the abutment 62 enters the inner cavity 2, the abutment 62 can generate an inward thrust by utilizing the rounded transition 622, thus eliminating the need for manual pressing and adjustment, making installation convenient.

[0023] The inner side of the abutment 62 is also provided with a guide sleeve 623 located outside the second insert 621 and arranged in a circle. The outer peripheral surface of the guide sleeve 623 fits against the inner peripheral surface of the assembly cavity 611. This can increase the stability of the abutment 62 when it moves, and the weight of the abutment 62 itself will not be transmitted to the spring 63, so the spring 63 will not bend, thus increasing the service life of the spring 63.

[0024] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
