Description

Technical Field

[0001] This utility model relates to a quick-release structure, and more particularly to a neck quick-release structure that allows the neck component of the support frame to be assembled or disassembled with the display as needed. Background Technology

[0002] With the advancement of technology, the development of monitors is one of the most representative products symbolizing technological progress. Today, monitors are widely used in computers, televisions, electronic magazines, etc. When monitors are used in homes and offices, most of them are movably connected to a stand, mainly to facilitate the monitor to be placed on a stand or mounted on a wall. Therefore, in the early assembly of the monitor and the stand, the two were assembled by screws. However, the use of screws does not have good load-bearing capacity and often breaks at the screw. Moreover, the screws are too troublesome for users to disassemble and assemble, and the screws are small and easy to lose. Therefore, relevant manufacturers have further introduced a form that can be directly plugged in for assembly, such as the neck quick-release structure in patent publication number CN220082649 and the neck quick-disassembly structure in patent publication number CN217422746.

[0003] The two examples listed above mainly describe the installation and assembly of the monitor and the stand. Although both technologies provide quick installation and disassembly of the monitor and the stand, in practice, the two examples have complex structures and a large number of parts, which makes the overall stand cost higher. Furthermore, due to the large number of parts, it is impossible to compress the packaging volume during the rear transportation process, resulting in excessive transportation costs and taking up too much space during transportation. Therefore, for companies in this field, the known structures mentioned above are not the optimal composition. Utility Model Content

[0004] The main purpose of this utility model is to maintain the original ease and convenience for users in assembling and disassembling the monitor and the stand, and further simplify and reduce the need for and use of parts, thereby reducing the overall cost. In addition, the volume of the packaging can be reduced due to the reduction and simplification of parts, thereby reducing transportation costs and space.

[0005] Accordingly, in order to address the deficiencies described in the prior art, this utility model provides a quick-release neck structure, comprising: a neck member including a mounting portion for connecting to a display, and a plug portion opposite to the mounting portion, the plug portion being movably inserted into and assembled to one end of a bracket assembly; the neck member having a side hole for a limiting member to be fixedly connected, one side of the neck member being recessed inward to form a sliding groove, the bracket assembly having a sliding hole at one end corresponding to the sliding groove to communicate with the sliding groove; and a control component installed in the sliding groove, the control component comprising: a locking member having a sliding rod and a locking element connected to one end of the sliding rod. A first pressing part is provided, the slide rod is provided with an elongated and laterally penetrating limiting groove, the limiting member passes through the side hole and the limiting groove in sequence so that the locking member can slide movably in the sliding groove, and the first pressing part can move in and out of one end of the sliding groove; and an elastic member, the two ends of which are elastically connected to the other end of the sliding groove and the other end of the slide rod of the locking member respectively; wherein, when an external force is applied to the first pressing part, the locking member is pressed to displace it in the sliding groove and compress the elastic member to generate elastic storage force, and when the first pressing part displaces to the other end of the sliding groove and disengages from the sliding hole, the neck member separates from one end of the bracket assembly.

[0072] To clearly illustrate the aforementioned objectives and effects achieved by this utility model, the embodiments of this utility model are described in detail below with reference to the accompanying drawings. This utility model mainly has two embodiments. Before describing each embodiment, the common technical features and structure are first described. This utility model provides a quick-release neck structure, which includes: a neck member 1, which includes a mounting part 11 connecting to a display 100. Components such as a spindle rod, a spring assembly, and a torsion spring (this is a common TILT hinge structure, so it will not be described in detail here) are threaded through the mounting part 11, allowing it to be assembled and combined with the display 100, and enabling the display 100 to swing up and down relative to the mounting part 11. A plug-in part 12, opposite to the mounting part 11, is movably inserted into and assembled to one end of a bracket assembly 2. The bracket assembly 2 provides that the display 100 can stand stably on a flat surface and be positioned at a certain height. The aforementioned flat surface can be a desktop, a wall, etc., and can be placed or clamped on a desktop or fixedly connected to a wall, and is not limited thereto. Additionally, a lifting module 24 can be installed within the bracket assembly 2 to allow the display 100 to move up and down relative to the bracket assembly 2 to adjust its height. The neck member 1 has a side through hole 121 for a limiting member 4 to be fixedly connected. One side of the neck member 1 is recessed inward to form a sliding groove 13. The side hole 121 and the sliding groove 13 are vertically connected to each other. The bracket assembly 2 is further provided with a sliding hole 213 at one end corresponding to the sliding groove 13 to connect to the sliding groove 13. In practice, the sliding groove 13 can be formed by the upper end of the neck member 1 being recessed downward or by the bottom being recessed upward, without limitation. A control component 3 is installed in the sliding groove 13 and used to control the movable assembly or disassembly of the neck member 1 relative to the bracket assembly 2.The control component 3 further includes a locking member 31 and an elastic member 32. The locking member 31 has a sliding rod 311 and a first pressing part 314 connected to one end of the sliding rod 311. The sliding rod 311 has an elongated, laterally penetrating limiting groove 312. The limiting member 4 passes sequentially through the side hole 121 and the limiting groove 312 to allow the locking member 31 to slide up and down within the sliding groove 13. The first pressing part 314 can move in and out of one end of the sliding groove 13. The two ends of the elastic member 32 are elastically connected to the other end of the sliding groove 13 and the other end of the sliding rod 311 of the locking member 31, respectively. Furthermore, the locking member 31 is spring-loaded by the elastic member 32, and one end of it protrudes from the sliding hole 213. When an external force is applied to the first pressing part 314, the first pressing part 314 is displaced towards the other end of the sliding groove 13 and disengages from the sliding hole 213, and the neck member 1 separates from one end of the bracket assembly 2. Pressing the locking member 31 causes it to displace within the sliding groove 13 and compresses the elastic member 32 to generate elastic storage force. One end of the elastic member 32 is limited and connected to a positioning groove 132 that extends inward at the other end of the sliding groove 13. The setting of the limiting member 4 restricts the movement range of the locking member 31.

[0073] Based on the above description of the main features of this utility model, its advantages are as follows: by combining the control component 3 with the neck piece 1, the control component 3 uses two parts, the locking element 31 and the elastic element 32, to replace the neck quick-release structure with a large number of parts in the prior art. For related manufacturers, this can significantly reduce personnel and manufacturing costs, as well as reduce the defect rate of the locking element 31 and the elastic element 32. In addition, it eliminates too many complex assembly forms in the assembly process, which not only reduces online assembly time but also reduces labor costs. For the operator, by applying force to press the locking element 31, the neck piece 1 can be quickly and easily pulled away from the support assembly 2. These technologies and features are more in line with the needs of users than the prior art listed in the known technology, and from a manufacturing perspective, it can produce and manufacture the best parts for use.

[0074] In addition to the main technical features described above, the following further describes other technical features and structural parts of the present invention. Firstly, based on the aforementioned common structural features, the present invention further includes two embodiments, which are first described in detail below. Figures 1 to 7The first embodiment of this utility model is shown. The bracket assembly 2 further includes a bracket connector 21, a connecting seat 22, a vertical frame 23, and a lifting module 24. One end of the bracket connector 21 has a cylindrical pivot protrusion 214, and the pivot protrusion 214 has a longitudinally penetrating first pivot hole 215. One end of the connecting seat 22 is fixedly connected to one side of the vertical frame 23, and the other end of the connecting seat 22 has a transversely cut pivot recess 221. The pivot recess 221 is correspondingly assembled and connected to the pivot protrusion 214, and the pivot recess 221 has a longitudinally penetrating second pivot hole 222. A shaft assembly 5 is used to pivotally connect the first pivot hole 215 and the second pivot hole 222, thus pivotally connecting the pivot protrusion 214. At the pivot recess 221, the bracket connector 21 is allowed to swing laterally relative to the connecting seat 22. The end of the bracket connector 21 opposite to the pivot protrusion 214 is a joint section 211. The joint section 211 is recessed inward from the end face to form a bracket opening 212 for the insertion part 12 to be inserted and assembled. The sliding hole 213 is provided on the bottom surface of the bracket connector 21 and communicates with the bracket opening 212. Therefore, according to the above-mentioned structural configuration of the bracket connector 21, when installing the neck piece 1, the user only needs to align the insertion part 12 at the end away from the control component 3 with the sliding hole 213 to facilitate quick installation. The left and right swing adjustment is achieved by the pivot setting between the pivot protrusion 214 and the connecting seat 22.

[0075] Continuing the above description, to prevent the user from being bumped by walls or surrounding objects when adjusting the placement of the monitor 100 horizontally, this utility model further provides an arc-shaped protrusion 216 on the pivot protrusion 214 of the bracket connector 21. In this embodiment, it is a block-shaped body protruding along the outer periphery of the pivot protrusion; see... Figures 4 to 7 As shown, the pivot recess 221 of the connector 22 is provided with an arc-shaped groove 223 corresponding to the arc-shaped protrusion 216. It is a short arc-shaped groove with two end faces. When the user wants to adjust the horizontal swing of the display 100, he only needs to move the bracket connector 21 to swing it relative to the stand 23. When the bracket connector 21 pivots relative to the stand 23, the arc-shaped protrusion 216 will slide arc-shaped within the arc-shaped groove 223 with the first pivot hole 215 and the second pivot hole 222 as the rotation center. The range of movement of the arc-shaped protrusion 216 is limited by the range of movement of the arc-shaped protrusion 216 against the two end faces of the arc-shaped groove 223, thereby reducing the damage caused by the display 100 colliding with external objects due to excessive horizontal swing angle.

[0076] For details regarding the second embodiment of this utility model, please refer to... Figures 8 to 15As shown, the difference between the second and third embodiments lies in the structural features that restrict the swinging of the display 100. In the second embodiment, an arc-shaped protrusion 216 is further protruded at either the top or bottom end face of the pivot protrusion 214 of the bracket connector 21 (the setting position is different from the first embodiment). The pivot recess 221 of the connecting seat 22 is provided with an arc-shaped concave rail 223 corresponding to the arc-shaped protrusion 216 (mainly set at the upper and lower outer edges of the pivot recess 221). The arc-shaped protrusion 216 is inserted into the arc-shaped concave rail 223 when the pivot protrusion 214 is installed in the pivot recess 221. When the bracket connector 21 pivots relative to the connecting seat 22, the arc-shaped protrusion 216 will move within the arc-shaped concave rail 223. The range of movement of the arc-shaped protrusion 216 is limited by the arc-shaped protrusion 216 abutting against the two end faces of the arc-shaped concave rail 223.

[0077] Please see Figure 11 , Figure 12 As shown, in the second embodiment, to provide a more stable assembly between the bracket connector 21 and the upright 23, a bracket housing 6 is further provided, which includes a main cover portion 61 and a ring portion 62. The main cover portion 61 is fitted onto the outside of the joint section 211 of the bracket connector 21, and the ring portion 62 surrounds the pivot protrusion 214. One end of the main cover portion 61 has a recessed main cover opening 611 for the bracket connector 21 to be inserted and assembled; and the ring portion 62... The inner wall surface of component 2 is provided with two snap-fit ​​ribs 621. The pivot protrusion 214 is recessed with two corresponding snap-fit ​​grooves 217 corresponding to the snap-fit ​​ribs 621. Each snap-fit ​​rib 621 engages with its corresponding snap-fit ​​groove 217 to limit the connection between the bracket housing 6 and the bracket connector 21. Furthermore, the second embodiment differs from the first embodiment in the operation of the locking member 31. In the first embodiment of this invention, the first pressing part 314 of the locking member 31 can be directly pressed (e.g., ...). Figure 4 , Figure 6 , Figure 7(As shown), but the second embodiment is set in an indirect control manner. It mainly involves providing a second pressing part 612 on the main cover 61 of the bracket housing 6 corresponding to the sliding hole 213. The second pressing part 612 is horizontally connected to the bottom of the main cover 61 via an elastic connecting section 613. The elastic connecting section 613 allows the second pressing part 612 to have elastic deformation margin when pressed by external force. The pressing of the second pressing part 612 causes it to swing towards the locking member 31 and then abut against the first pressing part 314, causing the locking member 31... The elastic member 32 is compressed inward, so in the second embodiment, the locking member 31 is operated indirectly by controlling the second pressing part 612. In addition, the thickness of the elastic connecting section 613 is thinner than that of the second pressing part 612, so that the second pressing part 612 has the capacity for elastic deformation. Finally, a second locking attachment 72 is inserted into and locked into the bracket connector 21 through an outer cover locking hole 615 formed at the connection between the elastic connecting section 613 and the bottom of the bracket housing 6, thereby enabling the bracket housing 6 and the bracket connector 21 to be firmly assembled together.

[0078] Having understood the partial forms of the first and second embodiments of this utility model, the locking member 31 will now be described below. Please see... Figures 3 to 5The locking member 31 shown in the first embodiment further forms a pressing surface 315 and an inclined guiding surface 316 at the end of the first pressing portion 314 of the slide rod 311. The pressing surface 315 and the inclined guiding surface 316 are not coplanar. The inclined guiding surface 316 is inclined towards the support assembly 2, so that the locking member 31 forms a notch in the direction of the support assembly 2. When the neck member 1 is inserted into the support assembly 21, the locking member 31 is locked in the direction of the support assembly 21. When the inclined guide surface 316 abuts against the bracket opening 212, it causes the locking member 31 to slide into the sliding groove 13, eliminating the need for the user to press the locking member 31 during assembly. When the neck member 1 slides within the bracket connector 21 and the first pressing part 314 of the locking member 31 slides to correspond to the sliding hole 213, the first pressing part 314 extends out from a slot 133 at one end of the sliding hole 213 and limits... The neck piece 1 is connected to the bracket connector 21. The shape of the slot 133 roughly matches the shape of the first pressing part 314 and is wider than the cross-sectional area of ​​one end of the sliding groove 13 to accommodate the first pressing part 314. Conversely, when the user needs to disconnect the neck piece 1 and the bracket assembly 2, he only needs to push the first pressing part 314 to disengage it from the slot 133 and the inner stop surface 317 of the first pressing part 314 abuts against one side of the slot 133, which can separate the neck piece 1 from the bracket assembly. The sliding rod 311 of the locking member 31 has a second guide part 313 on the side facing the bracket assembly 2. It is an arc-shaped curved surface. The sliding groove 13 has a first guide part 131 on the side corresponding to the second guide part 313. Its shape is the same as that of the second guide part 313, so as to prevent installation errors from affecting the operation of the locking member 31 and has the function of preventing mistakes.

[0079] Please see separately. Figure 11 , Figure 12 , Figure 14 The second embodiment of the present invention shown differs from the first embodiment in that: when the user unlocks, they press the aforementioned second abutment 612 to indirectly push against the first abutment 314, causing the lock fastener 31 to disengage inward from the sliding hole 213; another second guide part 313 is also provided on the outer periphery of the slide rod 311, but is provided on the side of the slide rod 311 facing the mounting part 11, and its shape is an elongated convex strip. The second guide part 313 extends from the other end of the slide rod 311 toward the first abutment 314, and the groove wall of the sliding groove 13 is recessed to correspondingly engage the first guide part 131 in relation to the provision of the second guide part 313. In the second embodiment, the elongated convex strips of the first guide part 131 and the second guide part 313 can simultaneously guide the lock fastener 31 to slide relative to each other in the sliding groove 13.

[0080] Please see Figures 2 to 3 , Figures 10 to 12 As shown, this quick-release neck structure also includes an outer sleeve 8 fitted onto the insertion portion 12 of the neck piece 1, and a first locking attachment 71 interlocks the outer sleeve 8 and the neck piece 1 together. The function of the outer sleeve 8 is to reduce the gap between the neck piece 1 and the bracket opening 212 of the bracket connector 21, and also to allow the neck piece 1 to smoothly insert into the bracket opening 212 to assemble the bracket connector 21. Therefore, when the outer sleeve 8 is needed, it is positioned between the insertion portion 12 and the bracket assembly 2 when it is movably inserted into the bracket assembly 2. The outer sleeve 8 has a recessed insertion groove 81 at one end corresponding to the mounting portion 11. A retaining rib 82 is formed around the edge of the insertion slot 81, and the mounting portion 11 of the neck member 1 is provided with a mounting stop surface 111. When the outer sleeve 8 is fitted onto the insertion portion 12 of the neck member 1 or when the insertion portion 12 is movably inserted into the insertion slot 81, the retaining rib 82 is engaged with the mounting stop surface 111 to limit its position. In addition, the outer sleeve 8 is tapered from the end with the retaining rib 82 toward the first locking accessory 71, thereby allowing the user to easily align one end of the outer sleeve 8 with the bracket opening 212 of the bracket connector 21 for insertion and assembly, so that the assembly between the neck member 1 and the bracket connector 21 is smooth.

[0081] In summary, the main technical advantage of this invention lies in its control component 3, which is composed of fewer parts (only two types: locking element 31 and elastic element 32). For manufacturers, reducing the number of parts undoubtedly reduces costs and eliminates the need for complex installation. Furthermore, the fewer parts and simpler design significantly improve production yield. Together, these factors contribute to a significant improvement in manufacturing compared to known products with complex structures. Additionally, the smaller number of parts offers greater advantages for transportation, particularly in packaging. It allows for smaller packaging, unlike known products with numerous parts that result in larger packaging volumes. Because of this smaller packaging, it doesn't occupy much space during transport, allowing for the transport of multiple units at once and reducing transportation costs. Therefore, this invention effectively solves the problems and shortcomings of known technologies, demonstrating considerable practicality and suitability for general use.
