Description

Technical Field

[0001] The utility model relates to the technical field of touch screens, in particular to a lockable touch screen support component. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to a pre-programmed program. It can be used to replace mechanical button panels and create vivid audio and video effects through liquid crystal display images. Common touch screens in life are generally used on electronic devices such as mobile phones or tablets. During use, for daily convenience, support components for devices such as tablets, namely tablet stands, are generally used.

[0003] For touch screen devices such as tablets, conventional support components will achieve different types of structural adjustment by adopting structures such as damping adjustment shafts. Although convenient, since this structure uses the friction force of the internal structure to generate structural support, this structural support will inevitably decline in structural stability as the number of uses and time increase, resulting in a decrease in structural support.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a lockable touch screen support assembly is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a lockable touch screen support assembly to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lockable touch screen support assembly, comprising a support frame and an adjusting shaft, the left and right sides of the support frame are symmetrically connected to a base, and a bidirectional screw rod is horizontally installed in the middle section of the base, the adjusting shaft is fixedly installed at the top front end of the base, and the top end of the adjusting shaft is connected to a limiting frame, and a support rod group is installed between the limiting frame and the base, and an anti-sliding block is installed at the bottom of the base.

[0007] Furthermore, the support frame and the base are connected to each other in a "mouth"-shaped structure, and the support frame horizontally penetrates the lower end of the base and is slidably connected to the base.

[0008] Furthermore, the bidirectional screw is threadedly connected to the middle part of the base, and the bidirectional screw and the support frame are arranged in a parallel structure with each other.

[0009] Furthermore, the adjustment shaft provides the limit frame with swing adjustment activity in the vertical direction with the adjustment shaft itself being circular, the bottoms of the left and right sides of the support frame are flush with the bottom of the anti-sliding block, and the anti-sliding block is symmetrically attached to the front and rear ends of the bottom of the base.

[0010] Furthermore, the limit frame includes a base frame, a limit block, a stop plate and a slide groove. The limit blocks are vertically installed at both the front and rear ends of the base frame, and a stop plate is provided on one side of the base frame, and a slide groove is opened at the bottom of the base frame.

[0011] Furthermore, the abutment plate is arranged on a side of the base frame away from the vertical central axis of the bidirectional screw rod, and the base frame, the limit block and the abutment plate are arranged in an integrated structure.

[0012] Furthermore, the support rod group includes a pneumatic telescopic rod, a movable shaft, a damping slider and a fixed pile. The front and rear ends of the pneumatic telescopic rod are equipped with movable shafts, and the end of the pneumatic telescopic rod close to the limit frame is connected to the damping slider through the movable shaft, and the end of the pneumatic telescopic rod close to the base is connected to the fixed pile through the movable shaft.

[0013] Furthermore, the fixing pile and the base are fixedly connected to each other, the damping slider and the slide groove are slidably connected, and the insides of the adjusting shaft and the movable shaft are both provided with a ratchet mechanism.

[0014] The utility model provides a lockable touch screen support assembly, which has the following beneficial effects:

[0015] 1. The utility model adopts a ratchet hinge-like structure for the adjusting shaft and the movable shaft, so that when adjusting the inclination angle of the limit frame, the structural characteristics of the adjusting shaft itself are utilized to have the structural mobility of turning and stopping, so that the adjusting shaft can provide the limit frame with flexible structural adjustment within a certain range, and also provide it with effective structural support. At the same time, since the pneumatic telescopic rod is connected to the slide groove at the bottom of the base frame through a damping slider arranged at one end, and the other end is connected to the base through a fixed pile, therefore, under the rotation adjustment of the movable shaft arranged between the pneumatic telescopic rod, the damping slider and the fixed pile, the entire support rod group can be synchronously telescoped and rotated and adjusted with the adjustment of different inclination angles of the limit frame, and under the structure and characteristics of the movable shaft, the pneumatic telescopic rod is further assisted to provide effective structural support for the limit frame, and within a certain mass support range, sufficient structural support of different inclination angles can be provided to touch screen devices such as tablets to the greatest extent, so as to facilitate the use needs of users.

[0016] 2. The utility model uses a bidirectional screw rod horizontally installed in the middle section of the base. When the bidirectional screw rod is rotated horizontally, the base threadedly connected to the left and right ends thereof will translate left and right along the surface of the bidirectional screw rod in the horizontal direction, thereby driving the limit frame connected to the top of the base through the adjustment shaft to move synchronously, thereby achieving the function of left and right clamping and fixing of touch screen devices such as tablets, and the use of the bidirectional screw rod structure also makes the base symmetrically arranged on the left and right have flexible structural adjustment, and the structure of the bidirectional screw rod is used to form the simplest locking structure, thereby preventing unnecessary structural deviation, and cooperating with the base frame surface The limit blocks and abutment plates arranged on the surface can prevent the possibility of the clamped tablet or other touch screen devices sliding off the entire limit frame to the greatest extent. At the same time, when the base connected to it is driven to translate under the adjustment of the two-way screw rod, the base will slide and translate along the surface of the support frame at the same time. The support frame ensures that the structures of the left and right bases are parallel to each other when they translate, and provides good structural support for the base, thereby forming a stable ground frame structure. In addition, the anti-sliding block attached to the bottom surface of the base can prevent the entire assembly from sliding when placed on the table to the greatest extent, further ensuring the stability of the overall use of the assembly.

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figures 1 to 4As shown, a lockable touch screen support assembly comprises a support frame 1 and an adjusting shaft 4, the left and right sides of the support frame 1 are symmetrically connected with a base 2, and a bidirectional screw rod 3 is horizontally installed in the middle section of the base 2, the adjusting shaft 4 is fixedly installed at the top front end of the base 2, and the top of the adjusting shaft 4 is connected to a limiting frame 5, and a support rod group 6 is installed between the limiting frame 5 and the base 2, and an anti-sliding block 7 is installed at the bottom of the base 2, a stop plate 503 is arranged on the side of the base frame 501 away from the vertical central axis of the bidirectional screw rod 3, and the base frame 501, the limit block 502 and the stop plate 503 are arranged in an integrated structure with each other, the support rod group 6 comprises a pneumatic telescopic rod 601, a movable shaft 602, a damping slider 603 and a fixed pile 604, and movable shafts 602 are installed at both ends of the pneumatic telescopic rod 601, and the end of the pneumatic telescopic rod 601 close to the limiting frame 5 is connected to the damping slider 6 through the movable shaft 602 03, and the pneumatic telescopic rod 601 is connected to a fixed pile 604 through a movable shaft 602 at one end close to the base 2, the fixed pile 604 and the base 2 are fixedly connected to each other, the damping slider 603 and the slide groove 504 are slidably connected, and the interior of the adjusting shaft 4 and the movable shaft 602 are both arranged with a ratchet mechanism. By adopting a structure similar to a ratchet hinge for the adjusting shaft 4 and the movable shaft 602, when adjusting the inclination angle of the limit frame 5, the structural characteristics of the adjusting shaft 4 itself are utilized to have a structural activity of turning and stopping. At the same time, under the rotation adjustment of the movable shaft 602 arranged between the pneumatic telescopic rod 601, the damping slider 603 and the fixed pile 604, the entire support rod group 6 can be synchronously telescoped and rotated and adjusted with the adjustment of different inclination angles of the limit frame 5, and under the structure and characteristics of the movable shaft 602, the pneumatic telescopic rod 601 is further assisted to provide effective structural support for the limit frame 5.

[0024] like Figures 1 to 4As shown, the support frame 1 and the base 2 are connected to each other in a "mouth"-shaped structure, and the support frame 1 horizontally passes through the lower end of the base 2 and is slidably connected to the base 2. The bidirectional screw rod 3 is threadedly connected to the middle part of the base 2, and the bidirectional screw rod 3 and the support frame 1 are arranged in parallel with each other. The adjustment shaft 4 provides the limit frame 5 with the swing adjustment activity in the vertical direction with the adjustment shaft 4 itself being circular. The bottom of the left and right sides of the support frame 1 is flush with the bottom of the anti-sliding block 7, and the anti-sliding block 7 is symmetrically attached to the front and rear ends of the bottom of the base 2. The limit frame 5 includes a base frame 501, a limit block 502, a stop plate 503 and a slide groove 504. The front and rear ends of the base 501 The limit blocks 502 are installed vertically, and a stop plate 503 is provided on one side of the base frame 501, and a slide groove 504 is provided at the bottom of the base frame 501. Through the bidirectional screw rod 3 installed horizontally in the middle section of the base 2, when the bidirectional screw rod 3 is rotated horizontally axially, the base 2 threadedly connected to the left and right ends thereof will translate left and right in the horizontal direction along the surface of the bidirectional screw rod 3, thereby driving the limit frame 5 connected to the top through the adjustment shaft 4 to move synchronously, thereby realizing the function of left and right clamping and fixing of touch screen devices such as tablets, and utilizing the structure of the bidirectional screw rod 3 to form the simplest locking structure to prevent unnecessary structural deviation.

[0025] In summary, if Figures 1 to 4 As shown, when using the lockable touch screen support assembly, first place the entire assembly on the table, so that the anti-sliding block 7 at the bottom of the base 2 and the bottom of the left and right sides of the support frame 1 are in contact with the table as much as possible, thereby ensuring that the entire assembly is stably placed on the table;

[0026] Then, the touch screen device such as a tablet to be used is placed between the limit frames 5 that are symmetrically arranged on the left and right, and the left and right sides of the bottom of the touch screen device are placed between the limit blocks 502 and the bottom frame 501, and then the bidirectional screw rod 3 in the middle of the base 2 can be rotated horizontally. As the bidirectional screw rod 3 rotates, the base 2 will be driven to translate horizontally along the surfaces of the support frame 1 and the bidirectional screw rod 3 toward the side of the touch screen device;

[0027] When the base 2 translates, the limit frame 5 connected to the structure by the adjustment shaft 4 will also move synchronously, thereby realizing the clamping and limiting operation of the side of the touch screen, until the abutment plate 503 firmly clamps the entire touch screen device in the middle of the entire assembly;

[0028] When the inclination angle of the touch screen device needs to be adjusted, it is only necessary to adjust the structural rotation of the shaft 4 and manually lift the limit frame 5 away from one end of the adjustment shaft 4, so that different inclination angles can be adjusted within a certain range. In this process, the support rod group 6 connected between the limit frame 5 and the base 2 will be adjusted synchronously. As the limit frame 5 is adjusted, the pneumatic telescopic rod 601 will simultaneously perform structural extension and contraction. At the same time, the damping slider 603 at one end of which is connected to the movable shaft 602 will slide along the surface of the slide groove 504 at the bottom of the base frame 501, and at the same time, it is fixed to the other end of the base 2 through the fixed pile 604, and the structural adjustment is performed under the structural rotation of the movable shaft 602. Under the adjustment of the above structure, the base 2, the limit frame 5 and the support rod group 6 will form an effective triangular support structure to ensure that the touch screen device still maintains its stability even when placed at different inclination angles.
