Description

Technical Field

[0001] The utility model belongs to the technical field of rubber cork detection, in particular to a presser foot and a rubber cork wood hardness tester. Background Art

[0002] The Shore measurement is the oldest, most widely used and most convenient method for measuring rubber hardness. The vast majority of rubber hardness testers used in my country are Type A Shore hardness testers, accounting for more than 90% of domestic rubber hardness testers. However, this type of rubber hardness tester is also used on rubber cork to detect the material data of rubber cork, thereby further improving the production quality of rubber cork.

[0003] However, there are some problems with the prior art: however, when the rubber hardness tester currently used to test rubber cork is used multiple times, the presser foot in contact with the rubber cork is prone to adhere to impurities on the rubber cork due to excessive downward pressure. Long-term and repeated use can easily cause the bottom of the presser foot to be uneven, resulting in the inability to ensure an accurate horizontal angle during subsequent testing of the rubber cork, thereby affecting the test data of the rubber cork. When manually cleaning, the force cannot be controlled according to the stability of the connection between the presser foot and the hardness tester, resulting in easy damage to the presser foot, thereby increasing the test cost of the rubber cork hardness. Therefore, we propose a presser foot and a rubber cork wood hardness tester. Utility Model Content

[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0025] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0026] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0027] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0028] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 5 As shown, a hardness tester presser foot provided by an embodiment of the utility model includes: a hardness tester, which is composed of a tester 103 and a presser foot 104, and the presser foot 104 is arranged at the bottom of the tester 103; an impurity cleaning component 2, which is composed of two groups of cleaning plates 201 and a driving component 202, and the driving component 202 is sleeved on the upper end of the outer side of the presser foot 104, and the driving component 202 is arranged at the bottom of the tester 103, the two groups of cleaning plates 201 are symmetrically and detachably arranged at the bottom of the driving component 202, and the two groups of cleaning plates 201 are both lifted and lowered at the bottom of the tester 103 by the driving component 202.

[0030] Since the two sets of cleaning plates 201 are both lifted and lowered at the bottom of the tester 103 by the driving component 202, the height positions of the two sets of cleaning plates 201 can be changed. Therefore, when the presser foot 104 installed at the bottom of the tester 103 has different specifications and models, the two sets of cleaning plates 201 can still clean it, thereby effectively improving the test data accuracy of the rubber cork wood hardness tester.

[0031] Furthermore, the driving component 202 includes two groups of threaded shells 2024, the upper end of the outer side of the presser foot 104 is slidably sleeved with a set shell 3, and the set shell 3 is fixedly connected to the bottom of the tester 103, the two groups of threaded shells 2024 are symmetrically rotatably installed on the bottom of the set shell 3, and the bottoms of the two groups of threaded shells 2024 are provided with threaded grooves, and the insides of the two groups of threaded grooves are connected by threads with screws 2025, and the lower ends of the two groups of screws 2025 are provided with connecting seats 2026, and the connecting seats 2026 are detachably connected to the cleaning plate 201; both ends of the upper surface of the set shell 3 are provided with rotating holes, and the threaded shells 2024 are rotatably installed on Inside the rotating hole, a protective shell 4 is fixedly installed on the upper surface of the set shell 3, and a groove is opened at the bottom of the protective shell 4. Both ends of one side of the inner groove are rotatably connected with driven gears 2022. The two groups of driven gears 2022 are respectively fixedly connected to the upper ends of the two groups of threaded shells 2024. A knob 2021 is fixedly installed in the middle of the upper surface of one group of driven gears 2022. The knob 2021 penetrates one end of the upper surface of the protective shell 4 to the inside of the groove. The middle part of one side of the inner groove is rotatably connected with a main gear 2023, and the main gear 2023 is hollow. Both groups of driven gears 2022 are meshed and connected with the main gear 2023;

[0032] Through the design that both sets of driven gears 2022 are meshed and connected with the main gear 2023, when one set of driven gears 2022 is rotated by rotating the knob 2021, the two sets of threaded shells 2024 can simultaneously control the rotation of the screw 2025, and the cleaning plate 201 is limited by the presser foot 104, so that the screw 2025 is lowered. Therefore, by turning the knob 2021, the two sets of cleaning plates 201 can be controlled to descend to the bottom of the presser foot 104, enter the cleaning area and perform cleaning work, thereby effectively preventing impurities on the rubber wood from accumulating at the bottom of the presser foot 104, and also preventing the presser foot 104 from being easily damaged when the staff uses manual cleaning.

[0033] Furthermore, a rotating shaft 7 is fixedly installed at the lower end of the screw 2025, a transmission groove is provided on the upper surface of the connecting seat 2026, multiple sets of triangular rubber blocks 6 are fixedly installed around the outer side of the rotating shaft 7, and the multiple sets of triangular rubber blocks 6 are arranged in a ring with equal distances, and multiple sets of triangular grooves are provided around the inner side of the transmission groove, and the triangular rubber blocks 6 are arranged correspondingly to the triangular grooves, and the triangular rubber blocks 6 are against the triangular grooves;

[0034] It is worth mentioning that a large part of the triangular rubber block 6 mentioned above is located inside the triangular groove. When the staff turns the knob 2021 too fast, in order to avoid excessive force between the cleaning plate 201 and the presser foot 104 and damage to the presser foot 104, the triangular rubber block 6 can control the screw 2025 to slip, thereby effectively avoiding the staff's incorrect operation and causing damage to the outer wall of the presser foot 104.

[0035] Furthermore, both ends of one side of the connection seat 2026 are provided with a card slot, and the two sets of card slots are connected to each other, and the two sets of card slots are slidably plugged with a plug-in block 8, and the two sets of plug-in blocks 8 are symmetrically fixedly installed on one end of the cleaning plate 201, and the two sets of card slots are slidably connected with a card column 10, and a linkage rod 11 is fixedly installed between the two sets of card columns 10, and the linkage rod 11 is slidably installed between the two sets of card slots, and arc grooves are provided on both sides of the plug-in block 8, and the arc grooves match the card column 10. , and the arc-shaped groove is arranged correspondingly to the card column 10, a linkage plate 12 is fixedly installed at one end of one group of card columns 10, a reset groove is opened on one side of one group of clamping grooves, the linkage plate 12 is slidably installed inside the reset groove, and reset springs 9 are fixedly installed at both ends of one side of the linkage plate 12, one end of the reset spring 9 is fixedly connected to one end inside the reset groove, and a pull rod 5 is fixedly installed in the middle of one side of the linkage plate 12, and one end of the pull rod 5 passes through one end inside the reset groove to the outside of the connecting seat 2026;

[0036] By matching the arc groove with the clamping column 10, when the cleaning plate 201 is used too many times and needs to be removed for cleaning, the pull rod 5 can be pulled to move the two sets of clamping columns 10 away from the arc groove, so that the cleaning plate 201 can be easily and quickly removed;

[0037] It is worth noting that the above-mentioned installation and removal method, using the limited clamping connection of two sets of clamping columns 10, can effectively and stably fix the cleaning plate 201, while also avoiding the serious wear caused by long-term installation and removal of traditional buckles, which affects the stability of later installation.

[0038] A rubber cork wood hardness tester comprises a wood hardness tester 1, which is composed of a test table 101 and a lifting seat 102. The lifting seat 102 is lifted and arranged on the upper surface of the test table 101, and a tester 103 is lifted and arranged at one end of the bottom of the lifting seat 102.

[0039] By designing that the tester 103 is lifted and arranged at one end of the bottom of the lifting seat 102, the tester 103 can be lowered linearly in a horizontal and vertical manner through the lifting seat 102, so that it can be stably attached to the surface of the rubber wood to perform hardness testing.
