Description

Technical Field

[0001] This utility model relates to the field of locking components, and in particular to an adjusting mounting screw assembly. Background Technology

[0002] When there are existing components to be installed, and fine-tuning is required, accessories are usually added to meet the technical requirements. For example, when installing wall joists, if adjustability is required, adjustment devices or components need to be added. This will sacrifice some of the usable indoor area to accommodate the installation of the adjustment devices or components.

[0003] See Figure 1 As shown, Figure 1 This is a schematic diagram of a screw used in the prior art to mount a component to a wall. The screw is screwed into both the component and the wall. When adjusting the horizontal distance between the component and the wall, the screw needs to be continuously turned. During this process, the screw rotates within the wall and the component, making it difficult to secure the component. Furthermore, repeated turning of the screw can easily damage it.

[0004] The applicant has discovered that the prior art has at least the following technical problems: Therefore, the screws (and other locking parts) in the prior art only have the function of fixing the part to be installed, and do not have the function of adjusting the distance between the part to be installed and the wall or other fixed objects, which is inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable mounting screw assembly to solve the technical problem that existing screws (and other locking components) only have the function of fixing the part to be installed, but do not have the function of adjusting the distance between the part and the wall or other fixed objects, which is inconvenient to use; the various technical effects of the preferred technical solutions provided by this utility model are described in detail below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The adjusting mounting screw assembly provided by this utility model includes a screw body, a bushing portion, and a bit assembly, wherein:

[0008] The screw body has a first threaded section and a limiting optical axis section, the insert is sleeved on the limiting optical axis section, and the limiting optical axis section and the insert are rotatable relative to each other; the insert is provided with a second threaded section, and the second threaded section has the same direction of rotation as the first threaded section;

[0009] The bit assembly and the socket have a fixed connection state and a disengaged state. When in the fixed connection state, the screw body and the socket can rotate synchronously under the drive of the bit assembly; when in the disengaged state, only the screw body rotates under the drive of the bit assembly.

[0010] Preferably, the limiting optical axis segment includes an optical axis body, a first limiting eave, and a second limiting eave, wherein:

[0011] The meson part is sleeved on the optical axis body, and the two are fitted with a clearance.

[0012] The first limiting eave and the second limiting eave are located at both ends of the optical axis body. The outer diameter of the first limiting eave and the outer diameter of the second limiting eave are both larger than the outer diameter of the optical axis body, which is used to prevent the meson part from detaching from the optical axis body.

[0013] Preferably, the bit assembly includes a first bit and a second bit, wherein:

[0014] The first batch head and the second batch head are of a separate structure, and the end of the screw body is provided with a connecting hole;

[0015] When in the fixed connection state, the first batch head is detachably snapped into the mesole part, and the second batch head passes through the first batch head and extends into the connection hole, thereby driving the screw body and the mesole to rotate synchronously;

[0016] When in the disengaged state, the second bit extends directly into the connecting hole, thereby only causing the screw body to rotate.

[0017] Preferably, the first batch head is provided with a limiting cavity, which extends through the opposite ends of the first batch head; the outer contour of the second batch head matches the limiting cavity, and when the second batch head passes through the limiting cavity and extends into the connecting hole, it can drive the first batch head to rotate synchronously.

[0018] Preferably, the radial cross-section of the limiting cavity is a polygonal structure.

[0019] Preferably, the second batch head includes an insertion portion, the outer contour of which is polygonal or polygonal, and the inner contour of the connecting hole matches the outer contour of the insertion portion.

[0020] Preferably, one of the mesiograph and the first batch head is provided with a slot, and the other is provided with a locking block. The locking block is inserted into the slot, thereby detachably and fixedly connecting the mesiograph and the first batch head.

[0021] Preferably, the meson portion is provided with slots, and the slots are arranged at intervals around the axial direction of the meson portion;

[0022] The first batch head is provided with a locking block, which is arranged at intervals along the axial direction of the first batch head. The locking block can be inserted into the locking slot along the axial direction of the mesophone, thereby realizing the synchronous rotation of the first batch head and the mesophone.

[0023] Preferably, the end of the meson portion is provided with a wedge-shaped block, the wedge-shaped blocks are arranged at intervals around the axial direction of the meson portion, the outer diameter of the wedge-shaped blocks gradually increases in the direction away from the axis of the meson portion, and the groove is formed between adjacent wedge-shaped blocks.

[0024] Preferably, the locking block extends along the axial direction of the first batch head, and the locking block is a fan-shaped block, the center of which is located on the axial direction of the first batch head.

[0025] The adjustable mounting screw assembly provided by this utility model has the following advantages compared with the prior art: When the part to be installed is fixed to a wall (or other fixed object), the bit assembly and the socket are in a fixed connection state. Rotating the bit assembly causes the screw body and the socket to rotate synchronously under the drive of the bit assembly. The screw body is driven into the wall (or other fixed object), and the socket is screwed into the part to be installed. Then, the bit assembly is removed, thereby fixing the part to be installed. After installation, when it is necessary to adjust the distance between the part to be installed and the wall, the bit assembly and the socket are disengaged, and only the screw body is connected to the bit assembly. Rotating the bit assembly causes only the screw body to rotate, while the socket remains stationary, ensuring the stability of the part to be installed during the adjustment process. Adjusting the depth of the screw body into the wall adjusts the distance between the part to be installed and the wall. The adjustable mounting screw assembly of this embodiment can achieve the purpose of installing and adjusting the installation distance and is easy to use. Attached Figure Description

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] In the description of this utility model, it should be understood that the terms "center," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] See Figure 1 As shown, Figure 1 This is a schematic diagram of a prior art structure where screws are used to mount a component to be fixed onto a wall 200. The screws are screwed into both the component 100 and the wall 200. When adjusting the horizontal distance between the component 100 and the wall 200, the screws need to be repeatedly turned. During this process, the screws rotate within the wall 200 and the component 100. It is difficult to secure the component 100 during adjustment, and repeated turning can easily damage the screws. Therefore, the screws (or other locking devices) in the prior art only serve to fix the component 100 and do not adjust the distance between the component and the wall 200 or other fixed objects, making them inconvenient to use.

[0041] To address the aforementioned problems, this utility model provides an adjustable mounting screw assembly that can achieve both installation fixation and adjustment of the installation distance, and is easy to use.

[0042] The following is combined with Figures 2-9 The technical solution provided by this utility model will be described in more detail.

[0043] Example 1:

[0044] See Figures 2-9 As shown, the adjusting mounting screw assembly provided by this utility model includes a screw body 1, a bushing portion 2, and a bit assembly. The screw body 1 has a first threaded section 11 and a limiting optical axis section. The bushing portion 2 is sleeved on the limiting optical axis section, and the limiting optical axis section and the bushing portion 2 are rotatable relative to each other. The bushing portion 2 is provided with a second threaded section 23, which has the same rotation direction as the first threaded section 11. The bit assembly and the bushing portion 2 have a fixed connection state and a disengaged state. When in the fixed connection state, the screw body 1 and the bushing portion 2 can rotate synchronously under the drive of the bit assembly. When in the disengaged state, only the screw body 1 rotates under the drive of the bit assembly.

[0045] The adjustable mounting screw assembly provided by this utility model, when the part to be installed 100 is fixed to the wall 200 (or other fixed object), the bit assembly and the insert part 2 are in a fixed connection state. Rotating the bit assembly causes the screw body 1 and the insert part 2 to rotate synchronously under the drive of the bit assembly. The screw body 1 is driven into the wall 200 (or other fixed object), and the insert part 2 is screwed into the part to be installed 100. Then, the bit assembly is disassembled, thereby fixing the part to be installed 100. After installation, see [reference needed]. Figure 9 As shown, when it is necessary to adjust the distance a between the part to be installed 100 and the wall 200, the bit assembly and the insert part 2 are disengaged, and only the screw body 1 is connected to the bit assembly. When the bit assembly is rotated, only the screw body 1 rotates, while the insert part 2 remains stationary, which can ensure the stability of the part to be installed 100 during the adjustment process. Adjusting the depth b of the screw body 1 entering the wall 200 is equivalent to adjusting the distance a between the part to be installed 100 and the wall 200.

[0046] As an optional implementation, see Figure 6 As shown, the limiting optical axis section includes an optical axis body 121, a first limiting eave 122, and a second limiting eave 123, wherein: the mesiograph 2 is sleeved on the optical axis body 121, and the two are fitted with a clearance; the first limiting eave 122 and the second limiting eave 123 are located at both ends of the optical axis body 121, and the outer diameter of the first limiting eave 122 and the outer diameter of the second limiting eave 123 are both larger than the outer diameter of the optical axis body 121, which is used to prevent the mesiograph 2 from detaching from the optical axis body 121.

[0047] The first limiting eaves 122 and the second limiting eaves 123 are used to restrict the axial movement of the mesole 2 along the screw body 1, thereby improving the stability of the structure. The gap between the mesole 2 and the optical axis 121 allows relative rotation between the mesole 2 and the optical axis 121.

[0048] As an optional implementation, see Figures 2-4 As shown, the screwdriver bit assembly in this embodiment includes a first bit 3 and a second bit 4, wherein the first bit 3 and the second bit 4 are separate structures, and a connecting hole 101 is provided at the end of the screw body 1; see also Figure 3 As shown, in the fixed connection state, the first batch head 3 is detachably snapped into the bushing part 2, and the second batch head 4 passes through the first batch head 3 and extends into the connection hole 101, thereby driving the screw body 1 and the bushing to rotate synchronously; see also Figure 4 As shown, when in the disengaged state, the second bolt head 4 extends directly into the connecting hole 101, thereby only causing the screw body 1 to rotate.

[0049] See Figure 3As shown, when the first batch head 3 is detachably snapped into the insert part 2, and the second batch head 4 passes through the first batch head 3, it can drive the first batch head 3 to rotate. Therefore, when the second batch head 4 drives the screw body 1 to rotate, the second batch head 4 also drives the first batch head 3 to rotate. Since the first batch head 3 is fixed to the insert part 2, the first batch head 3 drives the insert part 2 to rotate, thereby achieving synchronous rotation of the screw body 1 and the insert part 2.

[0050] As an optional implementation, see Figure 2 As shown, the first batch of heads 3 is provided with a limiting cavity 32, which extends through the opposite ends of the first batch of heads 3; the outer contour of the second batch of heads 4 matches the limiting cavity 32, and when the second batch of heads 4 passes through the limiting cavity 32 and extends into the connecting hole 101, it can drive the first batch of heads 3 to rotate synchronously.

[0051] See Figure 2 As shown, the radial cross-section of the limiting cavity 32 is a polygonal structure. Similarly, the outer contour of the part of the second batch head 4 that is inserted into the first batch head 3 is a polygonal structure. The second batch head 4 drives the first batch head 3 to rotate synchronously.

[0052] As an optional implementation, see Figure 8 As shown, the second batch head 4 includes an insertion part 41, the outer contour of which is polygonal or polygonal, and the inner contour of the connecting hole 101 matches the outer contour of the insertion part 41.

[0053] With the above structure, when the insertion part 41 extends into the connecting hole 101 at the end of the screw body 1, the screw body 1 can rotate synchronously with the second bit 4 when the second bit 4 is rotated.

[0054] As an optional implementation, one of the mesiograph 2 and the first batch head 3 is provided with a slot 21, and the other is provided with a block 31. The block 31 is inserted into the slot 21, thereby detachably and fixedly connecting the mesiograph 2 and the first batch head 3.

[0055] See Figure 5 and Figure 7 As shown, the meson section 2 is provided with a slot 21, which is arranged at intervals around the axis of the meson section 2; the first batch head 3 is provided with a block 31, which is arranged at intervals along the axis of the first batch head 3. The block 31 can be inserted into the slot 21 along the axis of the meson section 2, thereby realizing the synchronous rotation of the first batch head 3 and the meson section 2.

[0056] The above structure enables the first batch of head 3 and meson 2 to rotate synchronously, and facilitates their separation.

[0057] For details, see Figure 5As shown, a wedge block 22 is provided at the end of the meson section 2. The wedge blocks 22 are arranged at intervals around the axial direction of the meson section 2. The outer diameter of the wedge block 22 gradually increases in the direction away from the axis of the meson section 2. A groove 21 is formed between adjacent wedge blocks 22.

[0058] The above structure causes the inner diameter of the slot 21 to gradually increase in the direction away from the axis of the mesent part 2, which facilitates the insertion of the card block 31 on the first batch head 3 into the slot 21 and makes it easier for the two to separate.

[0059] As an optional implementation, see Figure 7 As shown, the card block 31 extends along the axis of the first batch head 3. The card block 31 is a sector-shaped block, and the center of the sector-shaped block is located on the axis of the first batch head 3.

[0060] The above structure facilitates the improvement of the stability of the connection structure between the first batch head 3 and the meson part 2, and enables synchronous coaxial rotation between the first batch head 3 and the meson part 2.

[0061] The adjusting mounting screw assembly provided by this utility model, when in use:

[0062] When fixing the component 100 to be installed to the wall 200 (or other fixed object), see Figure 3 As shown, the first batch head 3 engages with the insert part 2, and the second batch head 4 passes through the limiting cavity 32 of the first batch head 3. The insertion part 41 is inserted into the connecting hole 101 of the screw body 1. Rotating the second batch head 4 simultaneously drives the first batch head 3 to rotate. Since the first batch head 3 is fixed to the insert part 2, the first batch head 3 drives the insert part 2 to rotate. Thus, the screw body 1 and the insert part 2 can rotate synchronously, thereby fixing the part to be installed 100 to a fixed object such as the wall 200. Figure 9 As shown.

[0063] After the mounting component 100 is fixed, when it is necessary to adjust the distance 'a' between the mounting component 100 and the wall 200, only the second batch head 4 is installed, such as... Figure 4 As shown, the first batch of screw heads 3 is no longer installed (i.e., the first batch of screw heads 3 are detached from the retainer part 2). The second batch of screw heads 4 is rotated, and only the screw body 1 rotates while the retainer part 2 remains stationary. This ensures the stability of the part to be installed 100 during the adjustment process. The depth b of the screw body 1 entering the wall 200 is adjusted, which adjusts the distance a between the part to be installed 100 and the wall 200. During this adjustment process, the retainer part 2 remains stationary within the part to be installed 100, ensuring the effective fixation of the part to be installed 100.
