Description

Technical Field

[0001] The utility model relates to the technical field of leather processing, in particular to a leather clamping plate. Background Technique

[0002] For the sofas used at home, people generally sit or lie on them, so the using experience is very important. Therefore, leather sofas are favored because of their unique texture and durability.

[0003] The leather sewing process plays a crucial role in the whole process of making sofas. The sewing process not only relates to the structural strength of leather products, but also directly affects the appearance beauty of products. During the sewing process, a leather clamping plate is needed to clamp the leather.

[0004] Although some existing leather clamping plates can clamp the periphery of the leather, the clamping blocks are generally fixedly bonded to the bottom plate and cannot change their positions on the bottom plate. Therefore, they can only clamp one specification of leather, with a small application range and poor practicability. Content of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a leather clamping plate, which is used to solve the technical problems mentioned in the background technique that although some leather clamping plates can clamp the periphery of the leather, the clamping blocks are generally fixedly bonded to the bottom plate and cannot change their positions on the bottom plate. Therefore, they can only clamp one specification of leather, with a small application range and poor practicability.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A leather clamping plate includes a bottom plate. Two first chutes parallel to the length direction of the bottom plate, two second chutes parallel to the width direction of the bottom plate, and four third chutes corresponding to the four diagonals of the bottom plate are opened on the bottom plate. First mounting blocks are slidably arranged in the first chutes, second chutes, and third chutes. Elastic components are arranged on the side walls of each first mounting block arranged in the first chutes and second chutes, and the elastic components are respectively slidably arranged in the first chutes and second chutes. First locking pieces are arranged between the first mounting blocks arranged in the first chutes and second chutes and the bottom plate; a fourth chute is opened in each first mounting block, and a clamping block is slidably arranged in the fourth chute. A second locking piece is arranged between the clamping block and the first mounting block; the clamping block is divided into a lower plate and an upper plate. The lower plate of the clamping block is connected to the first mounting block, and a first rotating shaft is arranged between the upper plate and the lower plate. The upper plate is used to rotate and coincide with the lower plate to clamp the leather.

[0008] Working Principle:

[0009] During use, place the leather to be sewn on the clamping plate, then slide the first mounting blocks in the first chute, the second chute, and the third chute to appropriate positions respectively, and lock each first mounting block with the first locking member; and by checking the number of clamping blocks required, add or remove the first mounting blocks in the first chute, the second chute, and the third chute through the elastic component;

[0010] Then slide the clamping blocks in each first mounting block so that the clamping blocks can contact the leather surface, and lock each clamping block with the second locking member;

[0011] Then place the leather between the lower plate and the upper plate of the clamping block, and rotate the upper plate so that the upper plate covers the leather surface, thereby clamping the leather.

[0012] Beneficial effects:

[0013] In this solution, through the cooperation of the first chute, the second chute, the first mounting block, the first locking member, and the elastic component, the distance between two adjacent clamping blocks on the same side can be changed; and the number of first mounting blocks in the length direction and the width direction of the clamping plate can be changed, thereby avoiding the situation that when the number of first mounting blocks is limited, the perimeter of the leather becomes shorter, resulting in a dense distribution of the first mounting blocks on the same side of the clamping plate, and thus the distance between two adjacent clamping blocks on the same side is too small, affecting the sewing of the leather;

[0014] By providing the third chute, the fourth chute, the clamping block, and the second locking member, the depth of clamping the leather can be changed, preventing the situation of ineffective clamping due to too shallow clamping, and further causing the leather to separate from the clamping block during the sewing of the leather, affecting the sewing effect;

[0015] The combined use of the above components enables the clamping plate to clamp leathers of various specifications, with a large applicable range and good practicability. Description of the drawings

Detailed implementation mode

[0021] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] Embodiment:

[0023] As Figure 1 、 Figure 2 and Figure 4 shown, a leather clamping plate includes a bottom plate 1, two first chutes 2 parallel to the length direction of the bottom plate 1, two second chutes 3 parallel to the width direction of the bottom plate 1, and four third chutes 4 corresponding to the four diagonals of the bottom plate 1 are opened on the bottom plate 1. First mounting blocks 5 are slidably arranged in the first chute 2, second chute 3, and third chute 4. Elastic components are arranged on the side walls of each of the first mounting blocks 5 arranged in the first chute 2 and second chute 3. The elastic components are respectively slidably arranged in the first chute 2 and second chute 3. A first locking member is arranged between the first mounting blocks 5 arranged in the first chute 2 and second chute 3 and the bottom plate 1; a fourth chute 6 is opened in each of the first mounting blocks 5, and a clamping block 7 is slidably arranged in the fourth chute 6. A second locking member is arranged between the clamping block 7 and the first mounting block 5; the clamping block 7 is divided into a lower plate 702 and an upper plate 701. The lower plate 702 of the clamping block 7 is connected to the first mounting block 5. A first rotating shaft 8 is arranged between the upper plate 701 and the lower plate 702. Operating plates are fixedly arranged on both sides of the end of the upper plate 701 of the clamping block 7, and operating plates are also fixedly arranged on both sides of the end of the lower plate 702 of the clamping block 7. The two operating plates on the lower plate 702 of the clamping block 7 are rotatably sleeved at both ends of the first rotating shaft 8, and the two operating plates on the upper plate 701 of the clamping block 7 are fixedly sleeved at both ends of the first rotating shaft 8, and the two operating plates on the upper plate 701 of the clamping block 7 are arranged between the two operating plates on the lower plate 702 of the clamping block 7. The upper plate 701 is used to rotate and coincide with the lower plate 702 to clamp the leather.

[0024] In this solution, by setting up the cooperation of the first chute 2, the second chute 3, the third chute 4, the first mounting block 5, the first locking member, and the elastic component, the distance between two adjacent clamping blocks 7 on the same side can be changed; and by changing the number of the first mounting blocks 5 in the length direction and the width direction of the clamping plate, it is possible to avoid the situation where, when the number of the first mounting blocks 5 is limited, the perimeter of the leather becomes shorter, resulting in a dense distribution of the first mounting blocks 5 on the same side of the clamping plate, and thus the distance between two adjacent clamping blocks 7 on the same side is too small, which affects the sewing of the leather. By setting up the fourth chute 6, the clamping block 7, and the second locking member, the depth of clamping the leather can be changed, preventing the situation of ineffective clamping due to too shallow clamping, and further avoiding the detachment of the leather from the clamping block 7 during the sewing process of the leather, which affects the sewing effect.

[0025] As Figure 2 shown, the elastic component includes a first slider 9 and a second slider 10. The first slider 9 is fixedly arranged at the end of the first mounting block 5, and the first slider 9 is slidably arranged in the second slider 10. A slideway is formed in the bottom plate 1, and the second slider 10 is slidably arranged in the slideway, and the second slider 10 can be disengaged from the slideway. A spring 24 is fixedly arranged between the first slider 9 and the second slider 10. By squeezing the spring 24, the first mounting block 5 and the elastic component can be taken out of the bottom plate 1.

[0026] As Figure 1 shown, first threaded holes 11 are formed on the four edges of the top surface of the bottom plate 1. An auxiliary plate 12 is fixedly arranged on one side of the first mounting block 5 arranged in the first chute 2 and the second chute 3. Threaded holes are formed in the auxiliary plate 12. The first locking member is a first bolt 14, and the first bolt 14 is threadedly connected to the threaded holes and any one of the first threaded holes 11. After sliding the first mounting block 5 to a suitable position, the first bolt 14 is screwed into the threaded holes and the corresponding first threaded holes 11, so as to specifically realize the locking of the first mounting block 5, and this kind of operation is relatively convenient.

[0027] As Figure 1 、 Figure 2 and Figure 4As shown, a second mounting block 15 is slidably provided in each of the first mounting blocks 5, the lower plate 702 of the clamping block 7 is fixedly connected to the second mounting block 15, and the lower plate 702 of the clamping block 7 and the second mounting block 15 are bonded by glue; a row of second threaded holes 16 along the length direction of the first mounting block 5 is opened on one edge of the top surface of each of the first mounting blocks 5, two mounting plates 17 are fixedly provided on the top surface of the second mounting block 15, a second rotating shaft 18 is rotatably provided between the two mounting plates 17, a force-bearing plate 19 is fixedly sleeved on the second rotating shaft 18, and the second locking member is an arc-shaped locking block 20, which is fixedly provided on the side of the force-bearing plate 19 facing the first mounting block 5, and the arc-shaped locking block 20 is used to be inserted into any one of the second threaded holes 16, so as to lock the second mounting block 15. After adjusting the position of the clamping block 7, the force plate 19 is rotated, and the arc-shaped locking block 20 on the force plate 19 is inserted into the corresponding second threaded hole 16, thereby specifically locking the clamping block 7. This operation is relatively convenient.

[0028] like Figures 1 to 4 As shown, the lower plate 702 of the clamping block 7 includes a first connecting portion 7021 and a first clamping portion 7022, and the first connecting portion 7021 is fixedly provided with a baffle 23 on the side facing the upper plate 701 of the clamping block 7; the upper plate 701 of the clamping block 7 includes a second connecting portion 7011 and a second clamping portion 7012, and the second connecting portion 7011 is rotatably provided with a mounting shaft 21 on the side away from the lower plate 702 of the clamping block 7, and a locking block 22 is fixedly sleeved on the mounting shaft 21, and the locking block 22 is used to rotate between the baffle 23 and the second connecting portion 7011 when the upper plate 701 and the lower plate 702 overlap, so as to prevent the upper plate 701 from rotating and releasing the pressure on the leather.

[0029] The leather is placed on the surface of the first clamping part 7022 on the lower plate 702, and then the upper plate 701 is rotated, so that the second clamping part 7012 on the upper plate 701 covers the surface of the leather, and then the locking block 22 is rotated so that the locking block 22 is set between the baffle 23 and the second connecting part 7011 to press the leather. Figure 1 , Figure 3 and Figure 4 As shown, a protrusion 13 is fixedly provided on the locking block 22. The setting of the protrusion 13 prompts the operator to rotate the locking block 22 with less effort.

[0030] Working principle:

[0031] When in use, the leather to be sewn is placed on the clamping plate, and then the first mounting block 5 in the first slide groove 2, the second slide groove 3, and the third slide groove 4 are respectively slid to a suitable position, and the first bolt 14 is screwed into the threaded hole and the corresponding first threaded hole 11, so as to lock the first mounting block 5;

[0032] Check the required number of clamping blocks 7. By holding the first mounting block 5 and squeezing the spring 24 into the slideway, the spring 24 contracts and drives the first slider 9 to move towards the second slider 10. At this time, the end of the first mounting block 5 is disengaged from the connection with the first chute 2 or the second chute 3, so as to remove the redundant first mounting block 5; or by holding the first mounting block 5 and squeezing the spring 24 into the slideway, at this time, the end of the first mounting block 5 can extend into the first chute 2 or the second chute 3, and then release the extrusion of the first mounting block 5, the spring 24 elongates and pushes the first slider 9, so as to clamp the first mounting block 5 in the first chute 2 or the second chute 3, and then add the first mounting block 5;

[0033] Then slide the clamping block 7 in each first mounting block 5 so that the clamping block 7 can contact the leather surface. Rotate the force-bearing plate 19, and the arc-shaped locking block 20 on the force-bearing plate 19 is inserted into the corresponding second threaded hole 16, so as to realize the locking of the clamping block 7;

[0034] Then place the leather on the surface of the first clamping part 7022 on the lower plate 702, then rotate the upper plate 701, the second clamping part 7012 on the upper plate 701 covers the leather surface, then push the convex block 13 and rotate the locking block 22 so that the locking block 22 is arranged between the baffle 23 and the second connecting part 7011 to press the leather, and thus the whole operation is completed.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
