[0002] A worm gear refers to a gear with one or several helical teeth that meshes with a worm wheel to form an intersecting-axis gear pair. Its indexing surface can be a cylindrical surface, a conical surface or a toroidal surface. Existing worm gears are divided into two categories. One is an integrated structure of the rod body and the worm teeth, that is, a worm tooth structure is directly opened on the outer wall of the rod body to form an integrated worm gear structure. The other is a worm gear structure composed of a combination of a rod body and a worm tooth sleeve.

[0003] For the worm gear structure of the combination of the rod body and the worm tooth sleeve, the worm tooth sleeve is locked and connected to the rod body by inserting through the positioning holes opened on the rod body by bolts, so as to jointly form a worm gear structure. Since the worm gear needs to be used in cooperation with the worm wheel, in order to ensure the meshing transmission between the two, when installing the worm gear, it is necessary to ensure that the worm tooth sleeve on the outer wall of the worm gear always meshes with the outer wall of the worm wheel. However, in the actual installation process, since the position of the worm tooth sleeve on the outer wall of the worm gear cannot be adjusted, it is necessary to adjust the installation position of the worm gear or the worm wheel. In the setting of the machine body, such adjustment and installation operations are very inconvenient. Therefore, an adjustable worm gear is proposed. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides an adjustable worm as Figure 1-6 shown, including a rod body 1. A connection groove 101 is provided on the outer wall of the rod body 1. A worm gear sleeve 2 is arranged in the connection groove 101. A transmission groove 103 is provided at one end of the rod body 1, and the transmission groove 103 is used for the connection between the worm and the transmission structure.

[0026] It should be noted that a connection groove 101 is provided on the outer wall of the rod body 1. The area where the connection groove 101 is located is the area where the worm teeth of this worm are located, and the transmission groove 103 is used to connect the driving structure to drive the entire rod body 1 to rotate.

[0027] It further includes:

[0028] Adjustment jacks 102, and a plurality of adjustment jacks 102 are arranged along the horizontal center at the connection groove 101;

[0029] Connection sleeve 3, the connection sleeve 3 is arranged at both ends of the worm gear sleeve 2. A locking mechanism for locking the worm gear sleeve 2 is provided at the connection sleeve 3. The locking mechanism includes a connection screw 4 and a locking part. The locking part is threadedly inserted with the connection screw 4, and the connection screw 4 is used for the adjustment and positioning of the worm gear sleeve 2 by being inserted into different positions of the connection groove 101.

[0030] It should be noted that the inner diameters of the connection sleeve 3 and the worm gear sleeve 2 are the same as the outer diameter of the rod body 1 at the connection groove 101, so that the connection sleeve 3 and the worm gear sleeve 2 can be sleeved on the outer wall of the rod body 1 in a fitting manner.

[0031] Specifically, an insertion hole 301 is provided on the outer wall of the connection sleeve 3, a placement groove 302 is provided on the inner wall of the connection sleeve 3, the insertion hole 301 is connected to the placement groove 302 in a penetrating manner, the connection screw 4 is inserted into the insertion hole 301, and the locking part is arranged in the placement groove 302.

[0032] It should be noted that the insertion hole 301 is mainly used for the insertion of the connecting screw 4. When the connecting screw 4 slides along the outer wall of the connecting sleeve 3 towards the inner wall, its threaded end will gradually penetrate to the inner wall of the connecting sleeve 3. At this time, the threaded end of the connecting screw 4 will be inserted into the corresponding adjusting insertion hole 102, so as to fix the position of the connecting sleeve 3, and thus fix the position of the spiral gear sleeve 2.

[0033] Furthermore, a limiting ring 402 is arranged on the outer wall of the connecting screw 4, and the limiting ring 402 is inserted and connected in the placing groove 302.

[0034] It should be noted that through the setting of the limiting ring 402, under the insertion and cooperation of the limiting ring 402 and the placing groove 302, the connecting screw 4 will not move in the direction away from the connecting sleeve 3 and overflow from the insertion hole 301, thus avoiding the dropping of the connecting screw 4.

[0035] Still further, a rubber pressing block 401 is arranged at the threaded end of the connecting screw 4, and the rubber pressing block 401 is inserted and connected with the adjusting insertion hole 102.

[0036] It should be noted that through the setting of the rubber pressing block 401, when the connecting screw 4 moves in the direction away from the rod body 1, according to the setting of the limiting ring 402, when the connecting screw 4 moves to the farthest end away from the rod body 1, one-fifth of the rubber pressing block 401 will still be in the adjusting insertion hole 102, which also prevents the connecting sleeve 3 from being unstably connected and directly falling off the outer wall of the rod body 1.

[0037] Specifically, the locking part includes a locking collar 5. The locking collar 5 is arranged in the placing groove 302. A threaded hole is opened in the middle of the locking collar 5, and the locking collar 5 is threadedly inserted and connected with the threaded end of the connecting screw 4 through the threaded hole.

[0038] It should be noted that through the threaded insertion between the locking collar 5 and the connecting screw 4, the connecting screw 4 can move in the direction of approaching or moving away from the rod body 1 under the auxiliary guidance of the locking collar 5, so as to complete the insertion into the adjusting insertion holes 102 at different positions.

[0039] Furthermore, a plurality of limiting grooves 303 are opened at the notch of the placing groove 302 on the inner wall of the connecting sleeve 3, and a plurality of locking blocks 501 are arranged on the outer wall of the locking collar 5. The plurality of locking blocks 501 are respectively arranged in the plurality of limiting grooves 303.

[0040] Still further, one side of the locking collar 5 and the plurality of locking blocks 501 located on the inner wall of the connecting sleeve 3 is set as an arc wall that is attached to the inner wall of the connecting sleeve 3, and the arc wall is used for the sliding sleeve of the connecting sleeve 3 on the outer wall of the rod body 1.

[0041] It should be noted that through the cooperation setting of the limiting groove 303 and the locking block 501, the embedding depth of the locking collar 5 in the placement groove 302 is limited. At the same time, through the insertion and clamping between the limiting groove 303 and the locking block 501, the locking collar 5 can be stably positioned. At the same time, the connecting screw 4 can stably achieve the threaded mating operation by rotation. At the same time, in the setting of this solution, by using the setting of the arc-shaped wall, the setting of the locking collar 5 and the locking block 501 will not hinder the sliding insertion of the connecting sleeve 3 and the rod body 1.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
