Description

Technical Field

[0001] The utility model relates to the technical field of displays and accessories thereof, in particular to a quick-release mechanism for a display. Background Art

[0002] In the display quick-release mechanism in the prior art, the display assembly is provided with a twist arm, and a locking hook is provided at one end of the twist arm. After the display assembly is inserted into the base assembly along a first direction, the locking hook of the twist arm of the display assembly is hooked onto the engaging axis, and then the twist arm is accommodated in the storage groove of the display assembly. When the twist arm is accommodated in the storage groove, the extension direction of the twist arm is parallel to the second direction, and a limiting relationship along the first direction can be formed between the locking hook and the engaging axis, thereby limiting the display assembly from escaping from the base assembly in the opposite direction of the first direction.

[0003] However, in the prior art, due to the lack of a locking component between the storage slot and the torque arm, after the torque arm is accommodated in the storage slot, it is disengaged from the storage slot due to the vibration of the external environment or when the display quick-release mechanism is tilted during transportation. Once the torque arm is disengaged from the storage slot, the limiting relationship formed between the locking hook and the engaging axis along the first direction becomes invalid, and the display assembly can easily slide out of the base assembly in the opposite direction of the first direction.

[0050] Example 1

[0051] like Figure 1 to Figure 3 The present embodiment provides a quick-release mechanism for a display, which includes a base assembly 1 and a display assembly 2, wherein the display assembly 2 can be inserted into the base assembly 1 along a first direction; the base assembly 1 includes a bracket 101 and an engagement shaft 102, wherein the engagement shaft 102 is fixed to the bracket 101; the display assembly 2 includes a main body 201 and a twist arm 202, wherein the twist arm 202 is rotatably connected to the main body 201; a locking hook 203 is provided at one end of the twist arm 202, wherein the locking hook 203 can be hooked on the engagement shaft 102 or separated from the engagement shaft 102; a receiving groove 204 is provided on the main body 201, wherein the other end of the twist arm 202 extends out of the base assembly 1 and can be received in the receiving groove 204;

[0052] A first engaging member 3 is provided in the storage groove 204, and a second engaging member is provided on the torsion arm 202. The first engaging member 3 and the second engaging member can be engaged with each other or separated from each other; and the first engaging member 3 and the second engaging member can be switched between the two states of mutual engagement and mutual separation.

[0053] The engaging structure formed by the first engaging member 3 and the second engaging member may adopt one of the prior art. In this embodiment, the structures of the first engaging member 3 and the second engaging member are as follows:

[0054] like Figures 4 to 6The first engaging member 3 includes a support sleeve 301 and a stop pin 302 that is movably restricted in the support sleeve 301; along the second direction, the stop pin 302, the torsion arm 202, and the engaging shaft 102 are arranged in sequence; wherein the first direction is perpendicular to the second direction; a strip hole 303 is provided on one side surface of the support sleeve 301, and the strip hole 303 extends along the second direction; a dial head 304 is provided on one side of the stop pin 302, and one end of the dial head 304 extends out of the support sleeve 301 from the strip hole 303; a protrusion 305 is provided on the side of the stop pin 302 facing the torsion arm 202; the second engaging member is a groove 205 provided on the side of the torsion arm 202 facing the stop pin 302, and the protrusion 305 can be inserted into the groove 205 or separated from the groove 205.

[0055] After the dial head is subjected to an external force along the second direction or in the opposite direction of the second direction, it can move within the space limited by the hole wall of the strip hole 303; for example, the dial head is subjected to an external force along the second direction and moves toward the second direction until the protrusion 305 is inserted into the groove 205, and the first engaging member 3 and the second engaging member are in a mutually engaged state; the dial head is subjected to an external force along the opposite direction of the second direction and moves in the opposite direction of the second direction until the protrusion 305 and the groove 205 are separated from each other, and the first engaging member 3 and the second engaging member are in a mutually separated state.

[0056] Furthermore, in order to enable the protrusion 305 to automatically return to its original position and be inserted into the groove 205 after the external force in the opposite direction of the second direction applied to the dial head is removed, the present embodiment also includes the following technical solutions:

[0057] like Figures 4 to 6 The first engaging member 3 also includes a nail body 307 and a spring 308; a first cavity is set in the limit pin 302, and the first cavity forms a first opening 306 on the side surface of the limit pin 302 away from the torsion arm 202; the head of the nail body 307 is connected to the support sleeve 301, and the rod of the nail body 307 can be movably inserted into the first cavity through the first opening 306, and a limiting surface 309 is set on the rod of the nail body 307. Along the second direction, one end of the spring 308 abuts against the limiting surface 309, and the other end abuts against the inner wall of the first cavity.

[0058] In this embodiment, if the dial head is subjected to an external force in the opposite direction to the second direction and moves, the spring 308 is squeezed and contracted, and the protrusion 305 and the groove 205 are separated from each other; when the external force in the opposite direction to the second direction applied to the dial head disappears, the spring 308 pushes the limit pin 302 downward under the action of its own elastic force, thereby allowing the protrusion 305 to be inserted into the groove 205; that is, in this embodiment, after the external force in the opposite direction to the second direction applied to the dial head is removed, the protrusion 305 can automatically return to its original position and be inserted into the groove 205.

[0059] From the background technology, it can be seen that, in summary, the technical problems existing in the prior art are: how to prevent the torque arm from detaching from the storage groove after the torque arm is stored in the storage groove; in other words, how to form a locking relationship between the torque arm and the storage groove after the torque arm is stored in the storage groove.

[0060] In this embodiment, a first engaging member 3 is provided in the receiving groove 204, and a second engaging member is provided on the torsion arm 202. At the same time, the first engaging member 3 and the second engaging member can switch between two states of mutual engagement and mutual separation. When the first engaging member 3 and the second engaging member are in a mutually separated state, the torsion arm 202 can be separated from the receiving groove 204; when the first engaging member 3 and the second engaging member are in a mutually engaged state, that is, the first engaging member 3 and the second engaging member form a locking relationship, the positions of the torsion arm 202 and the receiving groove 204 are relatively fixed, and the torsion arm cannot be separated from the receiving groove. In summary, this embodiment solves the technical problem of how to form a locking relationship between the torsion arm and the receiving groove after the torsion arm is received in the receiving groove.

[0061] Furthermore, in the prior art, the following technical solution is usually included: a guide groove is arranged on the bracket of the base assembly, a slider is arranged on the main body of the display assembly, the guide groove has a first surface, and the slider has a second surface, and the guide groove and the slider form a sliding pair along the first direction through the first surface and the second surface. In the prior art, the area of ​​the first surface is usually equal to the area of ​​the second surface.

[0062] In the prior art, the processing of the plane is usually done by turning. Affected by the processing accuracy of the existing processing equipment, the flatness of the turning processing plane varies. In actual processing, it is very easy for protrusions or pits to appear on the processing plane. For example, there is a protrusion on the first surface and a pit on the second surface. Then, in the process of inserting the display assembly into the base assembly along the first direction, it is easy for the protrusion to get stuck in the pit, and a snap-fit ​​relationship along the first direction is formed between the protrusion and the pit, which makes the display assembly not inserted into the position of the base assembly, or the display assembly is difficult to separate from the base assembly after insertion. In order to reduce the occurrence of the above situation, it is usually necessary to reduce the sliding contact area between the guide groove and the slider. In this embodiment, the sliding contact area between the guide groove and the slider is reduced by the following technical solution.

[0063] like Figure 1 , Figure 7 , Figure 8As shown, a guide groove 103 is provided on the bracket 101, a slider 206 is provided on the main body 201, a first protrusion 207 is provided on one side of the slider 206, a first contact plane 208 is provided on one side of the first protrusion 207, and an area of ​​the first contact plane 208 is configured as a preset area. The slider 206 forms a sliding pair along a first direction with the guide groove 103 through the first contact plane 208, and, along the second direction, the slider 206 is inseparably restricted in the guide groove 103.

[0064] In this embodiment, a first protrusion 207 is provided on one side of the slider 206, and a first contact plane 208 is provided on the first protrusion 207. The area of ​​the first contact plane 208 is configured as a preset area, and the preset area is much smaller than the area of ​​the groove wall of the guide groove that is in sliding contact with the first contact plane 208. In this embodiment, the sliding contact area between the slider 206 and the guide groove 103 is only the area of ​​the first contact plane 208, that is, the preset area. This results in that the slider 206 of this embodiment has a smaller sliding contact area than the prior art during the sliding process relative to the guide groove 103 through the first contact plane 208. That is, this embodiment solves the technical problem of how to reduce the sliding contact area between the guide groove and the slider.

[0065] Furthermore, there are two groups of guide grooves 103 and sliders 206, which are respectively distributed on both sides of the main body.

[0066] Furthermore, in the above technical solution, the sliding contact area between the guide groove and the slider is reduced. Then, since the sliding contact area between the guide groove and the slider is the area of ​​the first contact plane 208, it is easy to cause the first contact plane 208 to bear a large pressure along the third direction, causing the slider to be crushed, wherein the third direction is perpendicular to the first direction and the second direction. In order to avoid this situation, this embodiment also includes the following technical solution.

[0067] The slider 206 is also provided with a second contact plane 209 ; the groove wall of the guide groove 103 is provided with a second protrusion 104 , and the second protrusion 104 is provided with a third contact plane 105 ; wherein the area of ​​the third contact plane 105 is smaller than the second contact plane 209 ; the second contact plane 209 is in sliding contact with the third contact plane 105 .

[0068] In this embodiment, the sliding contact area between the slider 206 and the guide groove 103, in addition to the preset area of ​​the first contact plane 208 mentioned above, also includes the area of ​​the third contact plane 105; in this embodiment, along the third direction, the pressure between the slider 206 and the guide groove 103 is shared by the first contact plane 208 and the second contact plane 209, thereby effectively preventing the slider from being crushed.

[0069] like Figure 9-10 Furthermore, the present embodiment also includes the following technical solutions: a limiting column 106 is also provided on the bracket 101, and a limiting hole 210 is provided on one side of the main body 201. The limiting column 106 can be inserted into the limiting hole 210 along the direction indicated by the first direction, or can be separated from the limiting hole 210; if the limiting column 106 is inserted into the limiting hole 210, a limiting relationship along the second direction is formed between the bracket 101 and the main body 201 through the limiting column 106 and the limiting hole 210.

[0070] As can be seen in the foregoing, along the second direction, the slider 206 is inseparably restricted in the guide groove 103, which results in the formation of a first layer of limiting relationship between the display assembly 2 and the base assembly 1 along the second direction; in this embodiment, a second layer of limiting relationship along the second direction is formed by the limiting column 106 and the limiting hole 210, which plays an auxiliary role in the first layer of limiting relationship.

[0071] like Figure 9-10 Furthermore, the present embodiment also includes the following technical solutions: the base assembly 1 also includes a fixing member 107 and a spring sheet 108, the spring sheet 108 is installed on the bracket 101 through the fixing member 107, and along the first direction, before the display assembly 2 is inserted into the base assembly 1, there is a gap between the spring sheet 108 and the bracket 101; the base assembly 1 also includes a connecting plate 109, the connecting plate 109 is connected to the bracket 101, and a through hole 110 is arranged on the connecting plate 109, and along the first direction, one end of the limiting column 106 abuts against one side surface of the spring sheet 108, and the other end can movably penetrate the through hole 110.

[0072] In this embodiment, during installation, the display assembly 2 is inserted into the base assembly 1 along the first direction under the action of an external force along the first direction, which causes the display assembly 2 to squeeze and push the limit column 106 along the first direction, so that the limit column 106 squeezes the spring sheet 108, and the spring sheet 108 deforms toward the bracket 101; after the external force along the first direction is removed, the spring sheet 108 pushes the display assembly 2 to move in the opposite direction of the first direction under the action of its own elastic force, giving the display assembly 2 an initial force that moves in the opposite direction of the first direction, making it easier to remove the display assembly 2 from the base assembly 1 during disassembly.

[0073] Furthermore, the present embodiment also includes the following technical solution: a plurality of deweighting holes 111 are provided on the bracket 101, and the deweighting holes 111 are formed by removing part of the material from the bracket 101. In the present embodiment, a plurality of deweighting holes 111 are provided on the bracket 101 to reduce the overall weight of the bracket 101.

[0074] Furthermore, the present embodiment also includes the following technical solution: a guide block 112 is further provided on the bracket 101, and a guide groove is provided at the bottom of the main body 201; the guide groove can form a sliding pair along the first direction with the guide block 112. In the present embodiment, by providing a guide mechanism between the bracket 101 and the main body 201, that is, a sliding pair along the first direction, the display assembly 2 is guided along the first direction during the process of inserting the display assembly 2 into the base assembly 1 along the first direction.

[0075] Furthermore, the present embodiment also includes the following technical solution: a socket is provided on the bracket 101; a plug is provided on the main body 201; the socket and the plug can be connected to each other or separated from each other.

[0076] During installation, the dial head 304 is toggled in the opposite direction of the second direction to rotate the torsion arm 202 out of the storage groove 204, and the display assembly is placed on the base assembly 1, so that the guide block 112 corresponds to the guide groove, and an external force along the first direction is applied to the display assembly. Under the sliding effect formed by the guide groove and the guide block 112, the main body 201 of the display assembly 2 slides into the bracket 101 of the base assembly 1 along the first direction; in this process, the slider 206 is gradually inserted into the guide groove 103, and the bracket 101 forms a restriction effect on the main body 201 along the second direction and the third direction through the guide groove 103 and the slider 206; when the main body 201 is pushed After being inserted into the bracket 101, the socket and the plug are plugged into each other; the torsion arm 202 is rotated so that the locking hook 203 is hooked on the engaging shaft 102, and the torsion arm 202 is continued to be rotated so that the end of the torsion arm 202 away from the engaging shaft 102 is accommodated in the receiving groove 204, and the torsion arm 202 and the receiving groove 204 form a locking relationship through the first locking component and the second locking component. The locking force formed between the locking hook 203 and the engaging shaft 102, as well as the spring piece 108 and the ejection force given to the main body 201 through the limiting column 106, make the main body 201 be restricted in the bracket 101 along the first direction; from then on, the installation steps of the display assembly 2 on the base assembly 1 are completed.

[0077] During disassembly, rotate the torque arm 202 to disengage the lock hook 203 from the engaging shaft 102; the spring piece 108 gives the main body 201 an elastic force in the opposite direction of the first direction, and the main body 201 is initially ejected from the bracket 101. Pull the torque arm 202 in the opposite direction of the first direction to completely disengage the display assembly 2 from the base assembly 1, thereby completing the disassembly step.

[0078] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
