Description

Technical Field

[0001] This utility model relates to the technical field of office furniture, and more specifically to a screen clip. Background Technology

[0002] Using desktop partitions to divide office cubicles is an economical and practical arrangement. First, partition clips are fixed to the desk surface. Then, partition panels are embedded within the clips, standing upright on the desk and dividing it into individual cubicles. Installation is simple, and removing or replacing the partition panels later is also convenient. Generally, manufacturers provide matching clips and panels; that is, one type of clip can only hold the corresponding panel, and replacement requires a panel of the same thickness and size. Upgrading to thicker panels necessitates replacing all clips, which is cumbersome and involves disassembling the old clips from the desk surface. New clips may not match the pre-drilled screw holes on the desk surface, requiring new holes to be drilled, increasing assembly difficulty. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a screen clamp that can change the clamping thickness to adapt to screen panels of different thicknesses and sizes.

[0004] The technical solution of this utility model is to provide a screen clip, including two clips arranged opposite each other and a clamping thickness adjustment member disposed between the two clips; a first support surface is provided on the upper and lower parts of one side of the clamping thickness adjustment member, and a second support surface is provided on the upper and lower parts of the other side of the clamping thickness adjustment member; the two clips are used to contact the two first support surfaces or the two second support surfaces respectively, and the distance between the two clips when contacting the two first support surfaces is less than the distance between the two clips when contacting the two second support surfaces.

[0005] Compared with the prior art, the screen clamp of this utility model has the following advantages: the contact position with the clamping piece can be changed by flipping the clamping thickness adjustment piece, thereby changing the clamping thickness of the screen clamp to adapt to screen panels of different thicknesses.

[0006] Preferably, a protrusion is provided on one side of the clamping thickness adjustment member, and the two first support surfaces are two opposing sidewalls of the protrusion. With this structure, the first support surfaces are simple in structure and easy to manufacture.

[0007] Preferably, a protrusion is provided on the other side of the clamping thickness adjustment member, and the two second support surfaces are the two opposite sidewalls of the protrusion. With this structure, the second support surface has a simple structure and is easy to process and manufacture.

[0008] Preferably, a third support surface is provided on the left and right sides of one side of the clamping thickness adjustment member. The third support surface and the first support surface are located on the same side of the clamping thickness adjustment member. The two clamping pieces can be used to contact the two third support surfaces respectively. The distance between the two clamping pieces when contacting the two third support surfaces is greater than the distance between the two clamping pieces when contacting the two second support surfaces. With this structure, the contact position with the clamping pieces can be changed by rotating the clamping thickness adjustment member, thereby changing the clamping thickness of the screen clamp and increasing the thickness specifications of the screen panels that the screen clamp can accommodate.

[0009] Preferably, both clamping pieces have a baffle at their heads. The upper surface of the baffle is a first mating surface, and a first limiting groove is provided on one side of the baffle. The first limiting groove includes a first limiting surface and a third limiting surface, both of which are positioned on the first mating surface. When the two clamping pieces are respectively connected to the two first supporting surfaces, the left and right ends of the clamping thickness adjustment member are respectively inserted into the first limiting grooves of the two clamping pieces, so that the left or right end face of the clamping thickness adjustment member mates with the first limiting surface on the corresponding side. The two first supporting surfaces mate with the first mating surfaces of the two clamping pieces, and the side of the clamping thickness adjustment member on the same side as the first supporting surface mates with the third limiting surface. With this structure, the two first support surfaces correspond to and engage with the first mating surfaces of the two clamping pieces, and the left or right end face of the clamping thickness adjustment member engages with the first limiting surface on the corresponding side. That is, the heads of the two clamping pieces are limited around the perimeter by the clamping thickness adjustment member, preventing misalignment on the table surface. The side of the clamping thickness adjustment member that is on the same side as the first support surface engages with the third limiting surface. That is, the heads of the two clamping pieces are limited by the clamping thickness adjustment member in the direction perpendicular to the table surface, preventing them from detaching from the clamping thickness adjustment member as the screen moves upward. In other words, the two clamping pieces are constrained by the clamping thickness adjustment member in three dimensions, preventing the two clamping pieces from sliding relative to the clamping thickness adjustment member in any direction.

[0010] Preferably, the heads of both clamping pieces are provided with a second mating surface parallel to the first mating surface at the upper end of the first limiting groove; when the two clamping pieces are respectively connected to the two second supporting surfaces, the left and right ends of the clamping thickness adjustment member are respectively inserted into the first limiting grooves of the two clamping pieces, so that the left end face or right end face of the clamping thickness adjustment member cooperates with the first limiting surface on the corresponding side, the two second supporting surfaces respectively cooperate with the second mating surfaces of the two clamping pieces, and the side of the clamping thickness adjustment member on the same side as the second supporting surface cooperates with the third limiting surface. With this structure, the two second support surfaces correspond to and engage with the second mating surfaces of the two clamping pieces, and the left or right end face of the clamping thickness adjustment member engages with the first limiting surface on the corresponding side. That is, the heads of the two clamping pieces are limited around the perimeter by the clamping thickness adjustment member, preventing misalignment on the table surface. The side of the clamping thickness adjustment member that is on the same side as the second support surface engages with the third limiting surface. That is, the heads of the two clamping pieces are limited by the clamping thickness adjustment member in the direction perpendicular to the table surface, preventing them from detaching from the clamping thickness adjustment member as the screen moves upward. In other words, the two clamping pieces are constrained by the clamping thickness adjustment member in three dimensions, preventing the two clamping pieces from sliding relative to the clamping thickness adjustment member in any direction.

[0011] Preferably, the inner side of the head of the clamping piece is provided with a second limiting groove consisting of two spaced-apart opposing limiting blocks and the baffle wall; when the two clamping pieces are respectively in contact with the two third support surfaces, the left and right ends of the clamping thickness adjustment member are respectively inserted into the second limiting grooves of the two clamping pieces, so that the two sides of the left end and the two sides of the right end of the clamping thickness adjustment member respectively cooperate with the two sides of the corresponding second limiting groove, the two third support surfaces respectively cooperate with the first mating surfaces of the two clamping pieces, and the side of the clamping thickness adjustment member on the same side as the third support surface cooperates with the bottom of the second limiting groove. With this structure, the two third support surfaces correspond to and engage with the first mating surfaces of the two clamping pieces, and the left and right end faces of the clamping thickness adjustment member engage with the two side walls of the second limiting groove, meaning that the heads of the two clamping pieces are limited by the clamping thickness adjustment member around their perimeter, preventing misalignment on the table surface. The side of the clamping thickness adjustment member that is on the same side as the third support surface engages with the bottom of the second limiting groove, meaning that the heads of the two clamping pieces are limited by the clamping thickness adjustment member in the direction perpendicular to the table surface, preventing them from detaching from the clamping thickness adjustment member as the screen moves upward. In other words, the two clamping pieces are constrained by the clamping thickness adjustment member in three dimensions, preventing the two clamping pieces from sliding relative to the clamping thickness adjustment member in any direction.

[0012] Preferably, the inner side of the head of the clamping piece is provided with a guide wall, and the opposite side of the guide wall is provided with a sliding groove. The two clamping pieces are arranged opposite each other, and the guide wall of one clamping piece slides into the sliding groove of the other clamping piece. With this structure, the two clamping pieces can remain aligned at all times when the clamping thickness is changed, avoiding misalignment.

[0013] Preferably, the inner side of the head of each clamping piece is provided with a countersunk hole, a nut is provided in the countersunk hole of one of the clamping pieces, and a connecting bolt is provided between the two clamping pieces. The connecting bolt is inserted into the countersunk hole of one clamping piece and threadedly connected to the nut in the countersunk hole of the other clamping piece. With this structure, the two clamping pieces are connected by a bolt, which facilitates changing the clamping thickness between the two clamping pieces.

[0014] Preferably, the clamping thickness adjustment component is provided with at least two connecting holes for external connection. With this structure, the screen clamp of this invention can be fixed to the table surface using screws, making operation convenient. Attached Figure Description

It should be understood that these detailed descriptions are merely illustrative of exemplary embodiments of this application and are not intended to limit the scope of this application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0027] It should also be understood that the terms "comprising," "having," "including," and "containing," when used in this specification, indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof. Furthermore, when expressions such as "...at least one" appear after a list of listed features, they modify the entire listed feature, not individual elements in the list. Example

[0028] like Figure 4 As shown, the screen clamp of this utility model includes two clamping pieces 2 arranged opposite each other, a bolt connecting the two clamping pieces 2, and a clamping thickness adjustment member 1 disposed between the two clamping pieces 2. The tail of the clamping piece 2 is used to clamp the screen, and the head of the clamping piece 2 is used to cooperate with the clamping thickness adjustment member 1. By adjusting the cooperation position between the clamping piece 2 and the clamping thickness adjustment member 1, the distance between the tails of the two clamping pieces 2 can be changed, that is, the clamping thickness of the screen clamp can be changed to adapt to screen panels of different thicknesses.

[0029] like Figure 1 and Figure 2As shown, the clamping thickness adjustment component 1 is sheet-shaped and has two connecting holes 1-1, which can be screwed onto the table surface. The four sides of the clamping thickness adjustment component 1 are parallel to each other in pairs, and the left and right end faces are both set as first mating surfaces 1-8. The upper and lower ends of the clamping thickness adjustment component 1 are each provided with a fifth mating surface 1-5 that respectively connects to the two first mating surfaces 1-8.

[0030] A protrusion, or boss, is provided on one side of the clamping thickness adjustment component 1. The upper and lower opposing sidewalls of the boss are both configured as first support surfaces 1-2. The upper and lower parts of the side of the clamping thickness adjustment component 1 containing the boss are each provided with a second mating surface 1-3. One of the two second mating surfaces 1-3 connects the upper end face of the clamping thickness adjustment component 1 to the corresponding first support surface 1-2, and the other connects the lower end face of the clamping thickness adjustment component 1 to the corresponding first support surface 1-2. The left and right opposing sidewalls of the boss are both configured as third support surfaces 1-6. The left and right parts of the side of the clamping thickness adjustment component 1 containing the boss are each provided with a sixth mating surface 1-7. One of the two sixth mating surfaces 1-7 connects the left end face of the clamping thickness adjustment component 1 to the corresponding third support surface 1-6, and the other connects the right end face of the clamping thickness adjustment component 1 to the corresponding third support surface 1-6. The second mating surface 1-3 and the sixth mating surface 1-7 can be the original sidewall of the clamping thickness adjustment part 1, or they can be a plane that has been processed later.

[0031] On the other side of the clamping thickness adjustment component 1, there are two protruding, parallel limiting ribs 1-9. The upper side of the upper limiting rib 1-9 and the lower side of the lower limiting rib 1-9 are both set as second support surfaces 1-4, that is, the two second support surfaces 1-4 are two opposing sidewalls on the two limiting ribs 1-9. The left and right end faces of the limiting ribs 1-9 are both set as third mating surfaces 1-10. In this embodiment, the third mating surfaces 1-10 and the first mating surfaces 1-8 are located on the same plane. The upper and lower parts of the side of the clamping thickness adjustment component 1 where the limiting ribs 1-9 are located are both provided with fourth mating surfaces 1-11. The fourth mating surfaces 1-11 are used to connect the fifth mating surface 1-5 located on the same side with the second support surfaces 1-4. The fourth mating surfaces 1-11 can be the original sidewall of the clamping thickness adjustment component 1 or a plane that has been processed later.

[0032] The two clips 2 have the same structure, such as Figure 5As shown, the inner side of the head of the clamping piece 2 is provided with a countersunk hole 2-1. A nut 2-10 is installed in the countersunk hole 2-1 of one clamping piece 2. The bolt connecting the two clamping pieces 2 is inserted into the countersunk hole 2-1 of one clamping piece 2 and threadedly connected to the nut 2-10 in the countersunk hole 2-1 of the other clamping piece 2. The distance between the two clamping pieces 2 can be adjusted by tightening the bolt. Each countersunk hole 2-1 of the clamping piece 2 is provided with a cover plate 2-2. The cover plate 2-2 prevents the countersunk hole 2-1 from being exposed and makes the outer surface of the clamping piece 2 flat.

[0033] like Figure 3 As shown, a guide wall 2-8 is provided on the inner side of the head of the clamping piece 2, and a sliding groove 2-9 is provided on the opposite side of the guide wall 2-8. The two clamping pieces 2 are arranged opposite each other, and the guide wall 2-8 of one clamping piece 2 slides into the sliding groove 2-9 of the other clamping piece 2. When adjusting the distance between the two clamping pieces 2, the guide walls 2-8 of the clamping pieces 2 slide along the corresponding sliding grooves 2-9 respectively, ensuring that the two clamping pieces 2 will not be misaligned.

[0034] The head of each clip 2 is provided with a baffle wall. The upper surface of the baffle wall is a first mating surface 2-3, and the inner sidewall of the baffle wall is a second limiting surface 2-4. The second limiting surface 2-4 stands below the first mating surface 2-3. A first limiting groove is provided on one side of the baffle wall. The first limiting groove includes a first limiting surface 2-7 and a third limiting surface 2-13, both of which stand on the first mating surface 2-3. The heads of both clips 2 are provided with a second mating surface 2-12 parallel to the first mating surface 2-3 at the upper end of the first limiting groove. The head of each clip 2 is provided with two spaced-apart opposing limiting blocks 2-11 on the inner side of the baffle wall. The two limiting blocks 2-11 and the baffle wall form a second limiting groove. The opposing sides of the two limiting blocks 2-11 are the two side walls of the second limiting groove, and the second limiting surface 2-4 is the bottom of the second limiting groove.

[0035] like Figure 4 and Figure 5As shown, when the two clamping pieces 2 are respectively connected to the two first support surfaces 1-2, the left and right ends of the clamping thickness adjustment member 1 are respectively inserted into the first limiting grooves of the two clamping pieces 2, so that the left or right end face of the clamping thickness adjustment member 1, i.e., the first mating surface 1-8, mates with the corresponding first limiting surface 2-7. The two first support surfaces 1-2 respectively mate with the first splicing surfaces 2-3 of the two clamping pieces 2. The side of the clamping thickness adjustment member 1 on the same side as the first support surface 1-2, i.e., the sixth mating surface 1-7, mates with the third limiting surface 2-13. At this time, tightening the bolts connecting the two clamping pieces 2 will keep the two clamping pieces 2 at the first clamping thickness. The two clamping pieces 2 are constrained by the clamping thickness adjustment member 1 in three dimensions, preventing the two clamping pieces 2 from sliding relative to the clamping thickness adjustment member 1 in any direction, and can stably clamp the screen that conforms to the first clamping thickness. In this embodiment, the first clamping thickness is 5 mm.

[0036] like Figure 6 and Figure 7 As shown, the clamping thickness adjustment component 1 is flipped back and forth so that the two clamping pieces 2 respectively contact the two second support surfaces 1-4. That is, the left and right ends of the clamping thickness adjustment component 1 are respectively inserted into the first limiting grooves of the two clamping pieces 2, so that the left or right end face of the clamping thickness adjustment component 1, i.e., the first mating surface 1-8, mates with the corresponding first limiting surface 2-7. The two second support surfaces 1-4 respectively mate with the second mating surfaces 2-12 of the two clamping pieces 2. The side of the clamping thickness adjustment component 1 on the same side as the second support surface 1-4, i.e., the fourth mating surface 1-11, mates with the third limiting surface 2-13. At this time, tightening the bolts connecting the two clamping pieces 2 will keep the two clamping pieces 2 at the second clamping thickness. The two clamping pieces 2 are constrained by the clamping thickness adjustment component 1 in three dimensions, preventing the two clamping pieces 2 from sliding relative to the clamping thickness adjustment component 1 in any direction, and can stably clamp the screen that meets the second clamping thickness. In this embodiment, the second clamping thickness is 9 mm.

[0037] like Figure 8 and Figure 9As shown, the clamping thickness adjustment component 1 rotates 90 degrees, so that the two clamping pieces 2 respectively connect with the two third support surfaces 1-6. The left and right ends of the clamping thickness adjustment component 1 are respectively inserted into the second limiting grooves of the two clamping pieces 2. The two sides of the left end and the two sides of the right end of the clamping thickness adjustment component 1 respectively cooperate with the two sides of the corresponding second limiting groove, that is, the four fifth mating surfaces 1-5 cooperate with the sides of the corresponding limiting blocks 2-11. The two third support surfaces 1-6 respectively cooperate with the first splicing surfaces 2-3 of the two clamping pieces 2. The side of the clamping thickness adjustment component 1 on the same side as the third support surface 1-6 cooperates with the bottom of the second limiting groove, that is, the sixth mating surface 1-7 cooperates with the second limiting surface 2-4. At this point, tightening the bolts connecting the two clamping pieces 2 maintains the two clamping pieces 2 at the third clamping thickness. The two clamping pieces 2 are constrained by the clamping thickness adjustment piece 1 in three dimensions, preventing the two clamping pieces 2 from sliding relative to the clamping thickness adjustment piece 1 in any direction, thus stably clamping the screen that conforms to the third clamping thickness. In this embodiment, the third clamping thickness is 12 mm.

[0038] In other embodiments, the large boss described above may not be required on one side of the clamping thickness adjustment member 1. Instead, two pairs of limiting ribs may be provided. One pair of limiting ribs is parallel to the upper and lower end faces of the clamping thickness adjustment member 1. The upper side face of the upper limiting rib and the lower side face of the lower limiting rib can be set as the first support surface 1-2. The other pair of limiting ribs is parallel to the left and right end faces of the clamping thickness adjustment member 1. The left side face of the left limiting rib and the right side face of the right limiting rib can be set as the third support surface 1-6.

[0039] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
