Description

Technical Field

[0001] This application belongs to the field of machine tools, and in particular relates to an installation tool for machine wood threads. Background Technology

[0002] like Figure 1 As shown, the machine-made wood thread 100 includes a machine thread 101 and a wood thread 102 connected to each other, wherein the wood thread 102 has a tip for driving into a wood structure such as wood; at least a portion of the machine thread 101 is located outside the wood structure for adjusting the driving depth of the wood thread 102.

[0003] The free end of a conventional machine thread 101 typically has a hexagonal hole 103. During use, an Allen wrench is inserted into the hexagonal hole 103, and then the machine thread 100 is screwed into the wooden structure, leaving a portion of the machine thread 101 protruding (adjusted in length as needed). However, this method makes the hexagonal hole 103 prone to deformation during frequent adjustments, leading to difficulties in assembling with other products and requiring rework. Furthermore, the protruding length of the machine thread 101 is unstable, making it difficult to ensure that the protruding portion is approximately of equal length. This is necessary in some situations, or in others, ensuring that the protruding portion is of approximately equal length allows for better arrangement of other structures, such as achieving layout stability.

Detailed Implementation

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] The first embodiment of this application provides an installation tool (which may be simply referred to as an installation tool) for machine-made wood threads, such as... Figure 2-6 As shown, the installation tool includes a first cylindrical section 1, a second cylindrical section 2, and a rod body 3. Wherein:

[0037] like Figure 2 and Figure 3 As shown, the first cylindrical part 1 is a cylindrical part that extends through the axis and is provided with internal threads 11 that can respectively mate with the second cylindrical part 2 and the rod body 3.

[0038] The first cylindrical section 1 has internal chamfers on its opposite sides to guide the entry of each external thread.

[0039] like Figure 4-6 As shown, the second cylindrical portion 2 is a hollow cylinder extending axially through, capable of accommodating at least a portion of the rod 3. The outer surface of the second cylindrical portion 2 is provided with a first external thread 21, which can engage with the internal thread 11 of the first cylindrical portion 1 to be screwed into the first cylindrical portion 1. In one embodiment, the first external thread 21 is only provided on a portion of the outer surface of the second cylindrical portion 2, located at the second end 23 of the second cylindrical portion 2 near the first cylindrical portion 1. By manually rotating the outer surface of the second cylindrical portion 2, the first external thread 21 can be screwed into the first cylindrical portion 1.

[0040] The rod 3 includes a head 31 and a tail 32, and a narrowed portion 33 located between them; wherein, at least a portion of the outer diameter of the head 31 and the tail 32 is larger than the inner diameter of the second cylindrical portion 2, and the outer diameter of the narrowed portion 33 is smaller than the inner diameter of the second cylindrical portion 2, so that the narrowed portion 33 is at least partially fitted into the second cylindrical portion 2, and the head 31 and the tail 32 are respectively located on both sides of the end of the second cylindrical portion 2, specifically, the head 31 is close to the first end 22 of the second cylindrical portion 2, and the tail 32 is close to the second end 23 of the second cylindrical portion 2.

[0041] In order to fit the shrinking part 33 into the second cylindrical part 2, with the head 31 and tail 32 located at its two ends, 3D printing technology can be used. Alternatively, the tail 32 can be cut off from the shrinking part 33 first, then the shrinking part 33 can be inserted into the second cylindrical part 2, and finally the tail 32 can be welded back to the shrinking part 33.

[0042] The head 31 is configured for rotating the rod 3. In one embodiment, the head 31 is a hexagonal shank; during rotation, an external hexagonal wrench is used to screw it in or out. In another embodiment, the free end of the head 31 may also be provided with a hexagonal hole; during rotation, an internal hexagonal wrench is used to screw it in or out. When the rod 3 is too thin, a hexagonal shank structure is superior to a hexagonal hole, as the hexagonal hole may make the head 31 prone to deformation, thus causing installation difficulties.

[0043] The tail portion 32 is provided with a second external thread 34, which can engage with the internal thread 11 of the first cylindrical portion 1, and can be screwed into or out of the first cylindrical portion 1 by rotating the head 31.

[0044] The installation tool is configured such that, in use, the first external thread 21 of the first cylindrical part 1 is screwed outwards, and the second external thread 34 of the first cylindrical part 1 is screwed inwards, so that the first external thread 21 can prevent the second external thread 34 from being screwed out excessively.

[0045] In one embodiment, the second cylindrical part 2 is a cylindrical hollow body, and the reduced part 33 is a circular rod, so that the rod 3 can rotate freely in the circumferential direction, while its movement in the radial and axial directions is restricted.

[0046] The first cylindrical portion 1 can be partially removed radially to expose the internal thread 11. The removed portion does not exceed half of the entire length, allowing for more direct observation of the movement of the second cylindrical portion 2 and the rod 3 within the first cylindrical portion 1 when using installation tools, and preventing the second cylindrical portion 2 and the rod 3 from falling out of the first cylindrical portion 1 due to an excessively large cross-section. Furthermore, it allows for control of the driving depth of the wood threads, ensuring that the driving depth of each wood thread is approximately equal.

[0047] The outer surfaces of the first cylindrical part 1 and the second cylindrical part 2 may be respectively provided with scales to indicate the screw-in depth, thereby more accurately controlling the driving depth of the wood thread.

[0048] When the internal thread 11 of the first cylindrical part 1 has a uniform structure, the tooth profile, nominal diameter, pitch, etc. of the first external thread 21, the second external thread 34 and the machine thread 101 of the machine wood thread are all the same, and they match the internal thread 11 of the first cylindrical part 1 at all points.

[0049] The second embodiment of this application provides an operation method for an installation tool for machine-made wood threads, including the following steps (see reference). Figure 7 and Figure 8 ):

[0050] Rotate the head 31 of the rod body to screw the second external thread 34 of the tail of the rod body into the first cylinder 1 (first end) and engage with the internal thread 11; then manually rotate the second cylinder to screw its first external thread 21 into the first cylinder 1 and engage with the internal thread 11; the position of the first external thread 21 is used to determine the driving depth of the wood thread 100.

[0051] like Figure 7 As shown, the machine thread 101 of the wood thread is screwed into the other end (second end) of the first cylinder 1 (it can be screwed in manually or by rotating the head 31 while holding the wood thread against it). The machine thread 101 moves axially upward to the second external thread 34 at the tail of the rod, and can continue to move upward, so that the second external thread 34 abuts against the first external thread 21 of the second cylinder. Due to the obstruction of the first external thread 21, the second external thread 34 and the machine thread 101 can no longer move upward (as shown). Figure 8 As shown), rotating the head 31 at this time will cause the wood thread 102 of the machine-made wood thread to begin to be driven into the wooden structure. When the first cylinder 1 comes into contact with the wooden structure, the screwing stops and the machine thread 101 is screwed out, and the installation of the machine-made wood thread is completed.

[0052] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0053] The above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific embodiments of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications should be covered within the scope of the technical solutions claimed in this application.
