Description

Technical Field

[0001] The utility model relates to the field of brackets, in particular to a wall-mounted telescopic bracket. Background Art

[0002] As a flexible and convenient support device, the wall-mounted telescopic bracket is widely used in various occasions that require wall-mounted installation. In the field of audio systems, it is particularly favored and becomes an important tool for supporting audio products and their supporting equipment. By wall-mounted installation, not only can the floor space be saved, but also the position of the audio can be flexibly adjusted according to the space layout, improving the auditory experience. However, the uses of the wall-mounted telescopic bracket are far more than this. It is also widely applicable to the wall-mounted installation of electronic products such as TVs, monitors, routers, etc., and the fixation of non-electronic products such as decorative paintings, storage racks and other household items, greatly enriching its application scenarios and meeting the personalized needs of different fields and spaces.

[0003] At present, the wall-mounted telescopic brackets on the market are mainly divided into two categories: telescopic and non-telescopic. The non-telescopic bracket has a fixed structure and a limited support range, making it difficult to meet the adaptation requirements of multi-specification products. Especially in the case of limited space or variable product specifications, its limitations are particularly obvious.

[0004] Although the telescopic bracket solves the problem of the support range to a certain extent, the existing telescopic brackets still have the following defects: 1) The telescopic table and the original support table are connected by double-layer superimposed slide rails. Due to the limitation of the telescopic structure between the telescopic table and the original support table, there is often a height difference and it is impossible to maintain horizontal consistency. This uneven support surface will directly affect the stability and balance of the supported product, increasing the risk of shaking or skewing after the product is installed; 2) Regarding the locking structure of the telescopic table, the existing technologies adopt loose locking screws or spring buckles and other designs. These locking structures are not only inconvenient to operate, but also easy to loosen after long-term use or bearing a certain weight, resulting in the telescopic part not being firmly fixed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above defects and provide a wall-mounted telescopic bracket, which can be telescopically adjusted, is convenient to adjust, and has stable support, solving the technical problems in the prior art that it is not convenient for telescopic adjustment, and the support performance is poor after elongation adjustment, affecting the support effect.

[0006] The purpose of the utility model is achieved in the following way:

[0007] Wall-mounted telescopic bracket, including a wall-mounted part and a support part. There are more than two mounting holes for mating and screwing in screws on the wall-mounted part. One end of the wall-mounted part is connected to the support part to form an L-shaped structure. On both sides of the support part, there are support platforms extending horizontally in opposite directions. Between the inner walls on both sides of the support part and the corresponding support platforms, there are chutes with opposite openings. The extending direction of the chute is the same as the extending direction of the support part, and there is a telescopic support plate that can slide horizontally along the chute. At the end of the telescopic support plate far from the wall-mounted part, there is a limiting part extending upward. The top surface of the telescopic support plate is a support plane, and the support plane is on the same horizontal plane as the top surface of the support platform. At the bottom of the support part, there is a locking screw hole, and there is a locking screw that can be screwed into the locking screw hole and used to press the support plate. One end of the locking screw can extend upward through the bottom of the support part to press the support plate.

[0008] Further, an L-shaped metal sheet for increasing rigidity is arranged inside the wall-mounted part and the support part. One end of the L-shaped metal sheet extends into the inside of the wall-mounted part, and the other end of the L-shaped metal sheet extends into the inside of the support part. Adding the L-shaped metal sheet can be used to increase the overall rigidity of the wall-mounted part and the support part, and at the same time, it can also increase the connection stability between the wall-mounted part and the support part, ensuring that the connection between the wall-mounted part and the support part has the stability of metal, is not easily deformed, and can bear heavier supported products.

[0009] Further, at one end of the L-shaped metal sheet extending into the inside of the wall-mounted part, there is a through hole corresponding to the position of the mounting hole, and at one end of the L-shaped metal sheet extending into the inside of the support part, there is a positioning hole for increasing the connection stability with the support part.

[0010] Further, both the wall-mounted part and the support part are made of plastic, and the L-shaped metal sheet is wrapped inside the wall-mounted part and the support part by injection molding. During the production process, first place the L-shaped metal sheet in the injection mold, and then inject the wall-mounted part, the support part, and the L-shaped metal sheet together by injection molding. The L-shaped metal sheet will be completely wrapped inside the wall-mounted part and the support part. During this process, the positioning hole will be filled with plastic to increase the connection stability between the L-shaped metal sheet and the support part.

[0011] Further, at one end of the support part close to the wall-mounted part, there is a limiting groove with an upward opening. The extending direction of the limiting groove is the same as the extending direction of the chute. At the bottom of the telescopic support plate, there is a limiting block protruding downward and extending into the limiting groove. The limiting block can slide along the limiting groove, and the sliding range of the limiting block in the limiting groove is the telescopic range of the telescopic support plate.

[0012] Further, at the bottom of the support part, there is a reinforcing boss surrounding the locking screw hole. The reinforcing boss is used to increase the thickness of the locking screw hole, thereby increasing the connection stability between the locking screw hole and the locking screw.

[0013] Furthermore, the bottoms of both sides of the support part are arc-shaped structures arranged symmetrically to each other. The support part arranged as an arc-shaped structure can strengthen the supporting force, so that the supporting platform can bear heavier products, and can improve the stability of the support.

[0014] The beneficial effects produced by the utility model are as follows: the arranged telescopic support plate can be freely slid and adjusted along the slide groove, so as to increase the support range of the support part; when the telescopic support plate is pulled outward in the direction away from the wall-hanging part, the support range can be gradually increased, so that it can be suitable for supporting wall-hanging products of different specifications; after adjusting to the appropriate length, the telescopic support plate can be locked by means of locking screws to avoid loosening of the telescopic support plate; the operation is simple and the adjustment is convenient; in addition, the supporting plane and the top surface of the supporting platform are in the same horizontal plane to ensure that the supporting surface can always be kept level; the supporting platform and the supporting plane can both contact with the supported product; the telescopic support plate can play a good supporting role in the extended state or the contracted state to ensure the stability of the supported product and avoid skewing and shaking of the supported product after installation due to the failure of the supporting surface to keep level.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] In this embodiment, referring to Figures 1-6 , the wall-mounted telescopic bracket implemented specifically includes a wall-mounted part 1 and a support part 2. There are three mounting holes 101 for mating and screwing in screws on the wall-mounted part 1. One end of the wall-mounted part 1 is connected to one end of the support part 2 to form an L-shaped structure.

[0024] An L-shaped metal sheet 5 for increasing rigidity is arranged inside the wall-mounted part 1 and the support part 2. Specifically, an iron sheet, an aluminum sheet or a steel sheet can be used. One end of the L-shaped metal sheet 5 extends into the inside of the wall-mounted part 1, and the other end of the L-shaped metal sheet 5 extends into the inside of the support part 2. A through hole corresponding to the position of the mounting hole 101 is arranged at the end of the L-shaped metal sheet 5 extending into the inside of the wall-mounted part 1, and a positioning hole for increasing the connection stability with the support part 2 is arranged at the end of the L-shaped metal sheet 5 extending into the inside of the support part 2. The wall-mounted part 1 and the support part 2 of this embodiment are both made of plastic, and the L-shaped metal sheet 5 is wrapped inside the wall-mounted part 1 and the support part 2 by an injection molding method. During the production process, the formed L-shaped metal sheet 5 is first placed in an injection mold, and then the wall-mounted part 1, the support part 2 and the L-shaped metal sheet 5 are injection molded into one body by injection molding. The L-shaped metal sheet 5 will be completely wrapped inside the wall-mounted part 1 and the support part 2. During this process, the through hole corresponds to the position of the mounting hole 101, and the positioning hole will be filled with plastic to increase the connection stability between the L-shaped metal sheet 5 and the support part 2.

[0025] Adding the L-shaped metal sheet 5 can be used to increase the overall rigidity of the wall-mounted part 1 and the support part 2, and at the same time can also increase the connection stability between the wall-mounted part 1 and the support part 2, ensuring that the wall-mounted part 1 and the support part 2 have the stability of metal after connection and are not easily deformed, and can bear heavier supported products. By wrapping the L-shaped metal sheet 5 with plastic, the plastic wall-mounted part 1 and support part 2 can avoid scratching the supported object due to improper installation.

[0026] Support platforms 201 extending horizontally in opposite directions are arranged on both sides of the support part 2. The bottoms on both sides of the support part 2 are symmetrically arranged arc-shaped structures. The support part 2 arranged in an arc-shaped structure can strengthen the support force, so that the support platforms 201 can bear heavier products and can improve the support stability. Sliding grooves 202 with opposite openings are formed between the inner walls on both sides of the support part 2 and the corresponding support platforms 201. The extending direction of the sliding grooves 202 is the same as the extending direction of the support part 2, and a telescopic support plate 3 that can slide horizontally along the sliding grooves 202 is arranged. A limiting part 301 extending upward is arranged at the end of the telescopic support plate 3 away from the wall-mounted part 1. The limiting part 301 is perpendicular to the top surface of the telescopic support plate 3, and the limiting part 301 is used to limit the supported object from sliding outwards. The top surface of the telescopic support plate 3 is a support plane 303, and the support plane 303 is on the same horizontal plane as the top surface of the support platform 201, such as Figure 1As shown, the two support platforms 201 are symmetrically arranged, and the two support platforms 201 are located on both sides of the support plane 303. When the telescopic support plate 3 is in a retracted state, the two support platforms 201 and the support plane 303 together form a square plane.

[0027] like Figure 5 and Figure 6 As shown, a limit groove 203 opening upward is provided at one end of the support portion 2 close to the wall hanging portion 1, and the extension direction of the limit groove 203 is consistent with the extension direction of the slide groove 202. A limit block 302 protruding downward and extending to the limit groove 203 is provided at the bottom of the telescopic support plate 3. The limit block 302 can slide along the limit groove 203, and the sliding range of the limit block 302 in the limit groove 203 is the telescopic range of the telescopic support plate 3.

[0028] like Figure 2 and Figure 3 As shown, a locking screw hole 204 is provided at the bottom of the support portion 2, and a locking screw 4 is provided which is screwed into the locking screw hole 204 and can be used to press the support plate. One end of the locking screw 4 can extend and press the support plate upward after passing through the bottom of the support portion 2. A reinforcing boss surrounding the locking screw hole 204 is provided at the bottom of the support portion 2. The reinforcing boss is used to increase the thickness of the locking screw hole 204, thereby increasing the stability of the screw connection between the locking screw hole 204 and the locking screw 4.

[0029] When installing the wall-mounted telescopic bracket of this embodiment, first fix the wall-mounted part 1 to the wall by matching the screws screwed into the mounting holes 101. At this time, the support part 2 extends outward along the wall to support the subsequently installed products. Then adjust the telescopic length of the telescopic support plate 3. For example, when installing a product of a smaller volume, no extension adjustment is required. First tighten the locking screw 4, and lock the telescopic support plate 3 by locking the locking screw 4 to prevent the telescopic support plate 3 from loosening. At this time, the telescopic support plate 3 is in a retracted state, such as Figure 1 As shown, the two support platforms 201 and the support plane 303 together form a square plane. When a larger product needs to be installed, the extension adjustment is required. First, loosen the locking screw 4, manually pull the telescopic support plate 3 outward in the direction away from the wall hanging part 1, and then lock the telescopic support plate 3 by the locking screw 4 after adjusting to a suitable length to prevent the telescopic support plate 3 from loosening. Figure 4 As shown, at this time, the telescopic support plate 3 is in an extended state, the support plane 303 extends outward, the two support platforms 201 and the support plane 303 are staggered, and the support plane 303 and the top surface of the support platform 201 are in the same horizontal plane, ensuring that the support surface can always be kept level, and both the support platform 201 and the support plane 303 can contact the supported product to ensure the stability of the supported product and avoid the supported product from tilting or shaking after installation due to the support surface not being able to keep level.

[0030] In addition, the wall-mounted telescopic bracket of this embodiment is not limited to being installed on the wall, but can also be flexibly applied to other positions that require support, such as being installed at the bottom of a table, at the bottom of a cabinet, on the inner panel of a cabinet, etc. Any position that provides support or fixed installation for the product is applicable.

[0031] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as the protection scope of the present utility model.
