Description

Technical Field

[0001] The utility model relates to the technical field of hardware clamps, in particular to a nut tightening clamp. Background Art

[0002] During the production and assembly of some products, due to their special design or light weight, the nuts on the products need to be tightened while the products are clamped. This is especially true when the product to which the nuts are connected is a hose. The tail nut is tightened and fixed at one end of the hose, and the end facing away from the hose and the hose are both relatively fixed before the tail nut is tightened using a wrench. The existing method of operation involves securing the product with a movable clamp and then tightening the nut with a wrench. Therefore, existing movable clamps either require repeated adjustments to tighten or loosen the product, or require manual tightening using tools. Consequently, the clamps of the prior art are cumbersome to use and are not conducive to efficient operation. Utility Model Content

[0003] The purpose of the utility model is to provide a nut tightening clamp, aiming to improve the convenience of tightening the nut.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] A nut tightening clamp comprises a clamp body, wherein the clamp body is formed with a first fixing position and a second fixing position;

[0006] The clamp body has a first mounting surface and a second mounting surface adjacent to each other;

[0007] The first fixing position has two first embedding grooves with continuous openings, and the openings of the first embedding grooves face the first mounting surface and the second mounting surface respectively; an opening of the first embedding groove is polygonal.

[0008] The second fixing position has an open second embedding groove, the opening of the second embedding groove is arranged toward the second mounting surface, the second embedding groove is a special-shaped groove, and the outer dimensions of the second embedding groove are different from those of the first embedding groove.

[0009] In one embodiment, the second embedding groove is a special-shaped platform, which consists of an upper bottom surface, a lower bottom surface and a side surface; the lower bottom surface is connected to the upper bottom surface through the side surface; the lower bottom surface is the opening of the second embedding groove, and the area of ​​the lower bottom surface is larger than the area of ​​the upper bottom surface.

[0010] In one embodiment, the lower bottom surface is in an arch shape, and the upper bottom surface is in a circular shape.

[0011] In one embodiment, the clamp body is further formed with a third fixing position, which is a third embedding groove having two continuous openings, and the openings of the third embedding groove are respectively facing the first mounting surface and the second mounting surface;

[0012] The cross section of the first embedding groove is rectangular;

[0013] The opening of the third embedding groove in the direction of the first mounting surface is rectangular, and the opening of the third embedding groove in the direction of the second mounting surface is arch-shaped, and the arc of the arch is away from the first mounting surface.

[0014] In one embodiment, the first fixing position includes a first limiting protrusion, which is provided on the first mounting surface and located at the opening of the first embedding groove; and / or,

[0015] The third fixing position includes a second limiting protrusion, and the second limiting protrusion is provided on the first mounting surface and is located at the opening of the third embedding groove.

[0016] In one embodiment, avoidance grooves are formed at the bottoms of the first embedding groove, the second embedding groove, and the third embedding groove.

[0017] In one embodiment, the fixture body has a third mounting surface opposite to the first mounting surface; the third mounting surface is used to fit with the fixed platform;

Specifically, when one end of the product is inserted into the first insertion groove, a wrench is used to tighten or loosen the nut. The end of the product can be fixed relative to the first insertion groove, which has a polygonal opening. After completing the corresponding operation on the nut, the operator only needs to easily remove the product and proceed to the next step. This improves the convenience of tightening the nut.

[0021] Furthermore, the second embedding groove is a special-shaped groove with an opening. It can be understood that the special-shaped groove is an irregular shape that is non-circular and non-equilateral, such as a shape formed by a combination of an arc and a straight line.

[0022] Therefore, when using the second insertion slot, the operator only needs to insert the product into the special-shaped slot, which can keep the product relatively fixed. After tightening the nut on the product, the product can be directly removed without any further operation on the clamp. The second insertion slot has different dimensions from the first insertion slot, so it can adapt to products of different sizes. Therefore, the provision of the second insertion slot further improves the convenience of nut tightening and enhances the applicability of the nut tightening clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the technical objectives, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] An embodiment of the utility model provides a nut tightening clamp.

[0039] See also Figures 1 to 5 In one embodiment of the present invention, the nut tightening fixture includes a fixture body 100 , and the fixture body 100 is formed with a first fixing position 110 and a second fixing position 120 ;

[0040] The clamp body 100 has a first mounting surface 101 and a second mounting surface 102 adjacent to each other;

[0041] The first fixing portion 110 has two first embedding grooves 110 a with continuous openings, and the openings of the first embedding grooves 110 a face the first mounting surface 101 and the second mounting surface 102 respectively; an opening of the first embedding groove 110 a is polygonal.

[0042] The second fixing position 120 has an open second embedding groove 120a, the opening of the second embedding groove 120a is set towards the second mounting surface 102, the second embedding groove 120a is a special-shaped groove, and the second embedding groove 120a has different external dimensions from the first embedding groove 110a.

[0043] It is understood that the technical solution of the present invention provides a first embedding groove 110a and a second embedding groove 120a; when tightening or loosening the nut 30, the product 40 with the nut 30 is embedded in the first embedding groove 110a or the second embedding groove 120a. Specifically, when one end of the product 40 is embedded in the first embedding groove 110a, the wrench 20 is used to tighten or loosen the nut 30. The end of the product 40 can be fixed relative to the first embedding groove 110a with a polygonal opening. After completing the corresponding operation on the nut 30, the operator only needs to easily remove the product 40 and proceed to the next step. This improves the convenience of tightening the nut 30.

[0044] Furthermore, the second embedding groove 120a is a special-shaped groove with an opening. It can be understood that the special-shaped groove is an irregular shape that is non-circular and non-equilateral, such as a shape formed by a combination of an arc and a straight line.

[0045] Therefore, when using the second embedding groove 120a, the operator only needs to embed the product 40 into the special-shaped groove. The special-shaped groove can relatively fix the product 40. After tightening the nut 30 on the product 40, the product 40 can be directly removed without any other operations on the clamp. In addition, the second embedding groove 120a has different external dimensions from the first embedding groove 110a, thereby adapting to products 40 of different sizes. Therefore, the provision of the second embedding groove 120a further improves the convenience of tightening the nut 30 and improves the applicability of the nut tightening clamp.

[0046] It should also be noted that an opening of the first embedding groove 110 a is polygonal. Specifically, the shape of the polygon can be a square or a regular hexagon.

[0047] Please continue reading Figure 1 In a specific embodiment, the second embedding groove 120a is a special-shaped platform, which consists of an upper bottom surface, a lower bottom surface and a side surface; the lower bottom surface is connected to the upper bottom surface through the side surface; the lower bottom surface is the opening of the second embedding groove 120a, and the area of ​​the lower bottom surface is larger than the area of ​​the upper bottom surface.

[0048] It can be understood that the special-shaped table is table-shaped, and has at least a pair of upper and lower bottom surfaces parallel to each other. When the area of ​​the lower bottom surface is larger than the area of ​​the upper bottom surface, the second embedded groove 120a further improves the applicable product 40 size range of the nut tightening clamp.

[0049] In one embodiment, the lower bottom surface is in an arch shape, and the upper bottom surface is in a circular shape.

[0050] It is understandable that the arcuate surface of the arch can be used to adapt to the arcuate product 40, and the right-angled surface of the arch can be used to relatively fix the product 40. Specifically, when the nut 30 is loosened or tightened, the product 40 can be relatively fixed.

[0051] See also Figure 1 、 Figure 2 and Figure 3 In one embodiment, the clamp body 100 is further formed with a third fixing position 130, which is a third embedding groove 130a having two continuous openings, and the openings of the third embedding groove 130a are respectively facing the first mounting surface 101 and the second mounting surface 102;

[0052] The first embedding groove 110a is a rectangular groove;

[0053] The third embedding groove 130 a is an arch-shaped groove, and the arc surface of the arch-shaped groove faces away from the first mounting surface 101 .

[0054] It is understandable that the arch-shaped curved surface can be used to adapt to the curved product 40, and the right-angled surface of the arch-shaped can be used to relatively fix the product 40. The provision of the third embedding groove 130a further improves the applicability of the nut tightening fixture.

[0055] See also Figure 1 、 Figure 3 and Figure 4 In one embodiment, the first fixing position 110 includes a first limiting protrusion 111, and the first limiting protrusion 111 is provided on the first mounting surface 101, at the opening of the first embedding groove 110a;

[0056] In one embodiment, the third fixing position 130 includes a second limiting protrusion 131 . The second limiting protrusion 131 is provided on the first mounting surface 101 at the opening of the third embedding groove 130 a .

[0057] It should be noted that the first limiting protrusion 111 and the second limiting protrusion 131 are provided to facilitate the installation of other accessories of the product 40 when the first embedding groove 110a or the second embedding groove 120a is relatively fixed to the product 40, thereby preventing the product 40 from rotating at will.

[0058] Further, if Figure 1 and Figure 2 As shown, the bottoms of the first embedding groove 110 a , the second embedding groove 120 a and the third embedding groove 130 a are all formed with avoidance grooves 110 b .

[0059] It can be understood that the avoidance groove 110b is provided to adapt to the specific shape of the product 40 on the one hand, and to relatively fix the product 40 on the other hand.

[0060] Specifically, if Figure 1 As shown, the fixture body 100 has a third mounting surface 103 opposite to the first mounting surface 101; the third mounting surface 103 is used to fit with the fixed platform;

[0061] The clamp body 100 is further formed with a through hole 104 , which is used for passing a screw through and fixing the nut tightening clamp to the fixing platform.

[0062] It is understandable that a nut tightening fixture fixedly mounted on a fixed platform is more conducive to improving the operating efficiency of the operator.

[0063] Optionally, the fixed platform is a desktop or an operating table.

[0064] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
