Description

Technical Field

[0001] The utility model relates to the technical field of watch straps, in particular to an improved watch strap adjustment unit. Background Art

[0002] The watch strap structures on the market include metal straps or leather straps. The assembly and connection method of metal straps generally includes multiple strap blocks, which are fixed by connecting columns passing through them. This structural fixation requires the use of specific tools to complete the disassembly and connection, which is very inconvenient when the length of the strap needs to be adjusted.

[0003] In order to overcome the above defects, there are also watch strap design structures on the market that can be disassembled and assembled by pulling out and rotating. Figure 1 When the rotating member 02 is pulled outward and rotated, the fixed column 01 protruding from the side is easily scratched by friction due to its position structure setting. In addition, the structural setting and installation of the existing product are relatively complicated, and there is a high production cost.

[0004] Therefore, it is urgent to provide an improved watchband adjustment unit to overcome the above-mentioned defects. Utility Model Content

[0005] The main purpose of the utility model is to provide an improved watchband adjustment unit, which overcomes the phenomenon of scratched products in the prior art, and is quick to assemble and reduces production costs.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An improved watchband adjustment unit comprises: a fixing unit, a fixing part and a rotating part installed on the left and right sides of the fixing unit in the width direction of the watchband, and an interference connection rod fixing assembly connecting the fixing unit, the fixing part and the rotating part;

[0008] A first clamping and fixing channel is formed in cooperation between the fixing member, the fixing unit and the rotating member, a second clamping and fixing channel is formed in cooperation between the fixing member and the rotating member, and a clamping limit portion is formed in the fixing member channel section in the first clamping and fixing channel and in the fixing member end;

[0009] The interference connection rod fixing assembly includes: an interference connection rod that penetrates the fixing member and the fixing unit and is interference connected with the rotating member, an elastic member limited by the interference connection rod and the clamping limit portion, and a first fixing rod installed in the second clamping fixing channel, which is interference connected with the fixing member and detachably clamped with the rotating member.

[0010] Preferably, the interference connection rod fixing assembly further comprises: a second fixing rod which is arranged between the first fixing rod and the interference connection rod and is respectively interference-connected with the fixing member and the fixing unit.

[0011] Preferably, the first fixing rod is parallel to the interference connection rod and is respectively installed on both sides of the fixing member and the rotating member in the length direction of the strap. After the rotating member is pulled outward, the rotating member rotates around the central axis of the first clamping fixing channel.

[0012] Preferably, when the elastic member is in a non-compressed state, the interference connecting rod section located in the channel section of the fixing member is greater than or equal to the insertion section of the first fixing rod inserted into the rotating member.

[0013] Preferably, an axial hole channel is formed through the portion of the fixing unit that protrudes from the fixing member and the rotating member and is parallel to the width of the strap, and the axial hole channel is connected through the first fixing rod corresponding to the adjacent strap adjustment unit.

[0014] Preferably, the first fixing rod is arranged on one side of the fixing unit in the length direction of the strap, and the shaft hole channel is located on the other side of the fixing unit in the length direction of the strap.

[0015] Preferably, the fixing member, the fixing unit, the rotating member and the interlocking connecting rod fixing assembly are assembled to form a "convex" shape.

[0016] Preferably, a clamping fixing pattern is protrudingly formed on the outer peripheral side of one end of the interference connection rod that is interference-connected with the rotating member, and a limiting ring for limiting the elastic member is protrudingly provided on the outer peripheral side of the other end.

[0018] Preferably, the horizontal bar of the fixing member in the width direction of the strap and the rotating member are connected with a third fixing rod.

[0019] Compared with the prior art, the utility model is an improved strap adjustment unit. When the rotating member is pulled outward, the interference connection rod and the clamping limiter work together to compress the elastic member. At this time, the rotating member is disengaged from the first fixed rod. The rotating member is rotated, and the rotating member drives the interference connection rod to rotate so that the adjacent strap adjustment unit can be removed from the first fixed rod or assembled on the adjacent strap adjustment unit. The structural setting is simple and reasonable. Due to the installation of the elastic member and the interference connection rod, the rotation force is easy to control, which overcomes the situation of the rotating friction product in the prior art.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] See also Figures 2 to 5 , an improved strap adjustment unit 100 of the present embodiment comprises: a fixing unit 1, a fixing member 2, a rotating member 3 and an interference connection rod fixing assembly 4, wherein the fixing member 2 and the rotating member 3 are respectively mounted on both sides of the fixing unit 1, and the interference connection rod assembly 4 fixes the fixing member 1, the fixing unit 1 and the rotating member 3. Specifically, a first clamping fixing channel is formed in the fixing member 2, the fixing unit 1 and the rotating member 3, a second clamping fixing channel is formed in the fixing member 2 and the rotating member 3, and a clamping limit portion is formed in the fixing member channel section in the first clamping fixing channel and in the end of the fixing member 2. The interference connection rod fixing assembly 4 includes: an interference connection rod 41 that penetrates through the fixing member 2 and the fixing unit 1 and is interference-connected with the rotating member 3, an elastic member 42 that is limited by the interference connection rod 41 and the clamping limit portion, a first fixing rod 43 that is installed in the second clamping fixing channel, is interference-connected with the fixing member 2 and is detachably clamped with the rotating member 3, and a second fixing rod 44 that is provided between the interference connection rod 41 and the first fixing rod and is respectively interference-connected with the fixing member 2 and the fixing unit 1. More specifically, a clamping fixing pattern is protrudingly formed on the outer peripheral side of one end of the interference connection rod 41 that is interference-connected with the rotating member 3, each of the clamping fixing patterns is parallel to the length of the interference connection rod 41, and the intervals between two adjacent clamping fixing patterns form a groove shape. A clamping limit portion that limits the elastic member 42 is protrudingly provided on the peripheral side of the other end. The fixing member channel section includes two hollow cylinders with different diameters, the two hollow cylinders penetrate the interference connection rod 41, and the hollow cylinder with a smaller diameter is located on the side facing the fixing unit 1, and the height of the hollow cylinder with a smaller diameter is 1mm-2mm. The fixing member 2 and the rotating member 3 of this embodiment are square structures, and the assembled strap adjustment unit 100 is an axisymmetric structure.

[0033] Specifically, if the elastic member 42 is installed in the rotating member 3, when the rotating member 3 rotates and disengages from the interference fit connecting rod 41, a virtual position will be formed in the channel hole connecting the rotating member 3 and the interference fit connecting rod 41. Due to the virtual position error, the difficulty of aligning the interference fit connecting rod 41 and the rotating member 3 is increased. However, the elastic member of the utility model is installed in the clamping limit portion of the fixed member, which effectively avoids the generation of virtual positions. During installation, accurate alignment can be achieved without adjustment, and installation is easier.

[0034] Specifically, the strap adjustment unit is assembled by multiple fixing units 1 in sequence. When the length of a single fixing unit 1 exceeds 9 mm, the second fixing rod 44 is interference connected between the fixing piece 2 and the fixing unit 1. This forms two connecting rod points between the fixing piece 2 and the fixing unit 1, namely the second fixing rod 44 and the interference connecting rod 41, which is beneficial to increase the connection stability between the fixing unit 1 and the fixing piece 2. The fixing piece 2 and the fixing unit 1 are not prone to relative rotation, thereby further improving the strength of the entire strap.

[0035] The fixing unit 1, the fixing part 2 and the rotating part 3 of the present embodiment are all made of the same material, which can be metal or hard plastic. The connection strength of the assembled metal strap and hard plastic strap is relatively high and is not easy to loosen.

[0036] In a preferred embodiment, the first fixing rod 43 is parallel to the interference connection rod 41 and is respectively installed on both sides of the fixing member 2 and the rotating member 3 in the length direction of the strap. After the rotating member 3 is pulled outward, the rotating member 3 rotates around the central axis of the first clamping fixing channel. When the elastic member 42 is in a non-compressed state, the interference connection rod section located in the fixing member channel section is greater than or equal to the insertion section of the first fixing rod 43 inserted into the rotating member 3. The fixing unit 1 is formed with an axial hole channel in parallel with the width of the strap, and the axial hole channel is connected by the first fixing rod corresponding to the adjacent strap adjustment unit. In this embodiment, the first fixing rod 43 is arranged on one side of the fixing unit 1 in the length direction of the strap, and the axial hole channel is located near the other side of the fixing unit 1 in the length direction of the strap. After the fixing member 2, the fixing unit 1, the rotating member 3 and the first fixing rod 43 are assembled, they are in a "convex" shape.

[0037] The structural setting of the present product installs the elastic member 42 in the fixing member 1, which is convenient for controlling the force when the present product is pulled outward and rotated. At the same time, the rotating member 3 rotates around the central axis of the rotating member clamping shaft hole section which constitutes the first clamping fixing channel, thereby avoiding the wear phenomenon caused by the limitation of position relationship when rotating in the prior art. In addition, the assembly method of the interference fit connecting rod 41 and the elastic member 42 also has the advantages of being simple and reliable. The design of the present structure simplifies the product structure and effectively reduces the production cost.

[0038] It can be seen from the above description that the structural setting of this product overcomes the phenomenon of scratched products in the prior art, and is quick to assemble and reduces production costs to a limited extent.

[0039] Please combine Figure 6 and Figure 7 The difference between the improved strap adjustment unit 100 of this embodiment and the above-mentioned embodiment is that the fixing member 2 ， The T-shaped fixing member 2 ， The two horizontal bars are parallel to the length and width directions of the strap, the first clamping fixing channel and the second clamping fixing channel are respectively located on the left and right sides of the horizontal bar parallel to the width direction of the strap, and the fixing unit 1 ， Specifically, one end of the horizontal bar parallel to the width direction of the strap of the strap adjustment unit 100 of this embodiment abuts against the rotating member 3 to position the rotating member 3. ， , and the left and right sides of the crossbar respectively abut against the fixing unit 1 ， For other structures, please refer to the description of the above embodiment and will not be repeated here.

[0040] The strap adjustment unit 100 of this embodiment is configured to adjust the elastic member 42 ， Installed on the fixing 1 ， It is convenient to control the strength of the product when it is pulled out and rotated. At the same time, the rotating part 3 ， The connecting rod 41 is rotated around the central axis of the rotating member engaging the shaft hole section constituting the first engaging fixing channel, thereby avoiding the wear caused by the positional relationship limitation during rotation in the prior art. ， And elastic member 42 ， The assembly method also has the advantages of being simple and reliable. The design of this structure simplifies the product structure and effectively reduces the production cost. ， A T-shaped horizontal bar parallel to the width direction of the strap is provided to abut against the rotating member 3 ， , further improving the stability of the product after assembly.

[0041] Specifically, the two horizontal bars of the T-shaped fixing member 2 include a long horizontal bar parallel to the width direction of the watchband, and a short horizontal bar parallel to the length direction of the watchband. The width of the long horizontal bar is 0.04-0.06mm longer than the width of the fixing unit 1, ensuring that the fixing unit 1 is installed between the T-shaped fixing member 2 and the rotating member 3. Furthermore, the width of the short horizontal bar is not less than 1.8mm. Since the elastic member 42 is assembled in the short horizontal bar of the T-shaped fixing member 2, the length of the elastic member 42 in the compressed state is 0.75mm. When disassembled, the elastic member 42 rebounds to generate a stroke of 0.8mm. Therefore, the width of the short horizontal bar is not less than 1.8mm to ensure the stable installation of the elastic member 42 and the clamping limiter. The structure of the entire watchband is very compact and the design precision is high, which is conducive to improving the added value of the product.

[0042] Please combine Figure 8 and Fig. 9 , this embodiment and Figure 6-7 The difference between the embodiments is that, on a horizontal bar parallel to the width direction of the strap, there are mounted two components respectively fixed to the horizontal bar and to the rotating member 3. ，， A detachably connected third fixing rod a.

[0043] The third fixing rod a is arranged so that the rotating member 3 ，， With fixings 2 ，， Three connection points are formed, specifically the rotating member 3 ，， Connecting rod 41 by interference fit ，， and T-type fixing 2 ，， Connection; through the second fixing rod 42 ，， and T-type fixing 2 ，， Through the third fixing rod a and T-shaped fixing member 2 ，， The long crossbar connection greatly improves the rotating part 3 ，， The connection stability is such that when one of the fixing rods is loosened, the entire rotating part 3 will not be damaged. ，， The product has high structural strength and good stability.

[0044] When in use, pull the rotating member 3 outward. ，， , Interference connecting rod 41 ，， The elastic member 42 is compressed in linkage with the elastic member 42 ，， , rotating part 3 ，， The first fixing rod 43 ，， The third fixing rod a is disengaged and the rotating member 3 is rotated. ，， , rotating part 3 ，， Rotate around one side, using the connecting rod 41 ，， and the elastic member 42 ，， Installed on the fixing 2 ，， Internal, by rotating part 3 ，， Drive the interference connecting rod 41，， Linkage compression makes the rotating member 3 ，， The force stability is good, which avoids the defect of product wear caused by misoperation due to poor force. The structural setting of this product is simple, which simplifies the product parts and effectively reduces the production cost.
