Description

Technical Field

[0001] The utility model relates to the technical field of railing construction, in particular to a positioning device. Background Art

[0002] For guardrails that need to be welded on site, during the welding process, the spacing and verticality of the guardrails must first be measured to determine the installation position of the guardrails before welding. For different use occasions, the design specifications have different requirements for the spacing and height of the guardrails. Usually, a tape measure or steel ruler is used to measure the spacing of the guardrails.

[0003] However, when measuring with a tape measure, the measurement result is usually inaccurate due to the bending of the tape measure on the side close to the reading; and when measuring with a steel ruler or a fixed-length rod made on site, it is only applicable to measurements of fixed spacing and is not applicable to different railing sizes.

[0004] Therefore, a retractable ruler is disclosed in the prior art, such as Figure 1 As shown, the retractable ruler includes a sliding slot frame 01, and a first ruler 02 and a second ruler 03 are slidably mounted inside the sliding slot frame 01. The two ends of the first ruler 02 and the second ruler 03 are respectively extended to the positions to be measured, and the total length of the second ruler 03 plus the reading of the first ruler 02 is the measured size.

[0005] The above-mentioned retractable ruler can be used to accurately measure the spacing of the railings and can quickly locate the installation position of the railings to be installed. However, during the measurement process, since the retractable ruler needs to be manually held to locate the installation position of the railing, the position of the retractable ruler will be tilted, resulting in inaccurate measurement results; secondly, if only one measurement is performed on the end of the railing, other positions of the railing may be tilted, and the verticality cannot be guaranteed; if multiple measurements are performed, the welding efficiency of the railing is reduced. Utility Model Content

[0006] In view of this, the utility model provides a positioning device to solve the problem that the existing tape measure or steel ruler cannot be adapted to the sizes of various railings and the handheld retractable ruler causes the installation position of the railing to be inaccurate.

[0007] The utility model provides a positioning device, which is suitable for positioning the distance between two adjacent parts to be installed, and includes:

[0008] Supports;

[0009] At least two retractable measuring pieces are fixedly connected to the support piece and spaced apart along the extension direction of the support piece. The extension direction of the retractable measuring piece is perpendicular to the extension direction of the piece to be installed. The retractable measuring piece has a scale and is suitable for performing retractable movement under the action of external force to adjust the distance between two adjacent pieces to be installed.

[0010] Beneficial effects: By adopting a retractable measuring piece to measure the distance between two adjacent parts to be installed, the application range is wide, and it can be applied to the measurement of installation dimensions of various parts to be installed, and the measurement result is more accurate than the traditional measurement method; by fixing the retractable measuring piece to the support member, it can prevent the retractable measuring piece from tilting due to the handheld measurement method, resulting in inaccurate measurement results; by setting at least two retractable measuring pieces, the distance between the extension directions of two adjacent parts to be installed can be measured multiple times at the same time, thereby ensuring that the parts to be installed do not tilt during installation, which can improve the installation quality of the parts to be installed, avoid rework, and improve measurement efficiency.

[0011] In an optional embodiment, the extension length of the support member is the same as the extension length of the member to be installed;

[0012] And / or, along an extension direction parallel to the part to be installed, the sum of the extension dimensions of the support member and the telescopic measuring member is the same as the extension length of the part to be installed.

[0013] Beneficial effect: Since the sum of the extension dimensions of the support member and the telescopic measuring member is the same as the extension length of the member to be installed, the two telescopic measuring members can abut against the welded frame of the member to be installed, without the need for a handheld positioning device, thereby preventing inaccurate measurements caused by manual operation.

[0014] In an optional embodiment, the retractable measuring member comprises:

[0015] An outer measuring piece having a hollow structure and having scales thereon;

[0016] At least one inner measuring piece, which is provided with a scale and can be slidably disposed in the hollow structure of the outer measuring piece, has a fixed state fixedly connected to the outer measuring piece and an active state slidably connected to the outer measuring piece.

[0017] Beneficial effects: By fixedly connecting the outer measuring piece with the inner measuring piece, the two ends of the telescopic measuring piece can be abutted between two adjacent pieces to be installed, thereby facilitating measurement; by setting the outer measuring piece and the inner measuring piece to be relatively movable, the telescopic length of the telescopic measuring piece can be adjusted to match the spacing between the pieces to be installed.

[0018] In an optional embodiment, a first limiting space is provided on the outer measuring member;

[0019] The retractable measuring member comprises:

[0020] The first limiting member cooperates with the first limiting space and is suitable for the inner measuring member to be in the fixed state when the first limiting member is inserted into the first limiting space and abuts against the inner measuring member.

[0021] Beneficial effect: By setting a first limit piece between the outer measuring piece and the inner measuring piece, the inner measuring piece can be fixed to prevent the inner measuring piece from being retracted inward when the retractable measuring piece is measuring, thereby preventing inaccurate measurement results.

[0022] In an optional embodiment, two inner measuring pieces are provided, respectively disposed at two ends of the outer measuring piece.

[0023] Beneficial effect: By setting two inner measuring pieces, the telescopic length of the telescopic measuring piece can be increased, and the measuring distance between two adjacent pieces to be installed can be expanded.

[0024] In an optional embodiment, a partition is provided in the hollow structure of the outer measuring member, and the two inner measuring members are provided on both sides of the partition;

[0025] And / or, a positioning member is provided in the hollow structure of the outer measuring member, and the positioning member is arranged opposite to the first limiting space, and when the inner measuring member is in the fixed state, the positioning member abuts against the inner measuring member.

[0026] Beneficial effects: By setting a partition in the hollow structure, the inner measuring piece can be limited to prevent the two ends of the inner measuring piece from completely extending into the hollow structure and being difficult to take out; by setting a positioning piece, the inner measuring piece can be kept horizontally placed in a fixed state, and the inner measuring piece can slide more smoothly in the hollow structure of the outer measuring piece.

[0027] In an optional embodiment, two retractable measuring members are provided, respectively disposed at two ends of the supporting member.

[0028] Beneficial effect: By providing retractable measuring parts at both ends of the support, the lower end of the positioning device can be placed horizontally on a plane, and the upper and lower ends of the installed part can be measured simultaneously, which can further ensure the verticality of the installed part.

[0029] Beneficial effect: By setting the support member as a retractable structure, it can be adjusted according to the length of the member to be installed, preventing the length of the support member from differing too much from the length of the member to be installed, so that only one retractable measuring member is used to measure the member to be installed, or the retractable measuring member can only be used to measure the distance at one end of the member to be installed, resulting in inaccurate measurement results and the verticality of the member to be installed cannot be guaranteed.

[0030] In an optional embodiment, the support member includes:

[0031] an outer support member having a hollow structure;

[0032] The inner support member is arranged in the hollow structure of the outer support member, and has a supporting state in which it is fixedly connected to the outer support member and a moving state in which it moves relative to the outer support member.

[0033] Beneficial effect: By arranging the outer support member and the inner support member to be relatively movable, the length of the support member can be adjusted to match the height of the member to be installed.

[0034] In an optional embodiment, a second limiting space is provided on the outer support member;

[0036] The second limiting member cooperates with the second limiting space and is suitable for the inner supporting member to be in the supporting state when the second limiting member is inserted into the second limiting space and abuts against the inner supporting member.

[0037] Beneficial effect: By arranging a second limit member between the outer support member and the inner support member, the inner support member can be fixed to prevent the inner support member from being retracted inward during measurement, which would lead to inaccurate measurement results.

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0049] Combine the following Figures 2 to 6 , describing an embodiment of the utility model.

[0050] According to an embodiment of the utility model, a positioning device is provided, which is suitable for positioning the distance between two adjacent parts to be installed 1, including: a support member 2; at least two retractable measuring members 3, which are fixedly connected to the support member 2 and are arranged at intervals along the extension direction of the support member 2, the extension direction of the retractable measuring members 3 is perpendicular to the extension direction of the part to be installed 1, and the retractable measuring members 3 have scales, which are suitable for performing retractable movement under the action of external force to adjust the distance between two adjacent parts to be installed 1.

[0051] By adopting the retractable measuring piece 3 to measure the distance between two adjacent parts to be installed 1, the scope of application is wide, and it can be applicable to the measurement of installation dimensions of various parts to be installed 1, and the measurement result is more accurate than the traditional measurement method; by fixing the retractable measuring piece 3 to the support member 2, it can prevent the retractable measuring piece 3 from tilting due to the handheld measurement method, which leads to inaccurate measurement results; by setting at least two retractable measuring pieces 3, the distance between the extension directions of two adjacent parts to be installed 1 can be measured multiple times at the same time, thereby ensuring that the part to be installed 1 does not tilt during installation, which can improve the installation quality of the part to be installed 1, avoid rework, and improve the measurement efficiency.

[0052] The component 1 to be installed in this embodiment is a railing. As a convertible implementation, the component 1 to be installed can also be other structures that need to be positioned and installed, and no excessive restrictions are made here.

[0053] Wherein, when in use, the positioning device is set to one, such as Figure 3 As shown, two retractable measuring pieces 3 are provided, which are respectively provided at the two ends of the support member 2. Along the extension direction parallel to the railing, the sum of the extension dimensions of the support member 2 and the retractable measuring piece 3 is the same as the extension length of the railing. By providing the retractable measuring pieces 3 at both ends of the support member 2, it is convenient to place the lower end of the positioning device horizontally on a plane, and the upper end and the lower end of the railing can be measured simultaneously, which can further ensure the verticality of the railing; at the same time, since the sum of the extension dimensions of the support member 2 and the retractable measuring piece 3 is the same as the extension length of the railing, the two retractable measuring pieces 3 can be abutted against the welded frame of the railing, without the need to hold the positioning device, to prevent inaccurate measurement caused by manual operation. As a convertible embodiment, it is also possible that a plurality of positioning devices are provided and set to different sizes. When it is necessary to measure the size of the railing, several positioning devices are assembled according to the length of the railing, so that the sum of the sizes of the assembled plurality of positioning devices is adapted to the height of the railing. As a convertible embodiment, it is also possible that three or four retractable measuring members 3 are provided, and the number of retractable measuring members 3 is determined according to the length of the railing and the actual situation, and no excessive restrictions are made here. As a convertible embodiment, it is also possible that when the retractable measuring member 3 is provided at a non-end position of the support member 2, the extension length of the support member 2 is the same as the extension length of the railing.

[0054] The support member 2 in this embodiment is a telescopic structure. By setting the support member 2 as a telescopic structure, it can be adjusted according to the length of the railing, preventing the length of the support member 2 from being too different from the length of the railing, so that only one telescopic measuring member 3 is used to measure the railing, or the telescopic measuring member 3 can only be used to measure the spacing at one end of the railing, resulting in inaccurate measurement results and the verticality of the railing cannot be guaranteed.

[0055] Specifically, Figure 6 As shown, the support member 2 in this embodiment includes: an outer support member 21, which has a hollow structure; an inner support member 22, which is arranged in the hollow structure of the outer support member 21, and has a supporting state fixedly connected to the outer support member 21 and a moving state relative to the outer support member 21. By setting the outer support member 21 and the inner support member 22 to be relatively movable, it can be used to adjust the length of the support member 2, thereby matching the height of the railing. As a convertible embodiment, it is also possible that the support member 2 includes a plurality of support units, and the plurality of support units are fixed by plug-in or bolt connection, and then a suitable number of support units can be selected for assembly according to the height of the railing.

[0056] Among them, the inner wall of the outer support member 21 is threadedly connected with the outer wall of the inner support member 22. The support member 2 can achieve telescopic movement through the threaded connection between the outer support member 21 and the inner support member 22, with a simple structure and convenient operation. As a convertible embodiment, it is also possible that the inner wall of the outer support member 21 and the outer wall of the inner support member 22 are both smooth structures, and the outer support member 21 and the inner support member 22 are clearance-matched to achieve relative telescopic sliding under the action of external force. As a convertible embodiment, it is also possible that through holes are arranged at intervals on the outer support member 21, and a retractable protrusion is provided on the inner support member 22. When the protrusion is not engaged with the through hole, the outer support member 21 and the inner support member 22 can move telescopically relative to each other, and when the protrusion is engaged in the through hole, the outer support member 21 and the inner support member 22 are relatively fixed.

[0057] Furthermore, if Figure 6 As shown, the outer support member 21 is provided with a second limiting space 211; the support member 2 includes: a second limiting member 23, which cooperates with the second limiting space 211, and is suitable for the inner support member 22 to be in a supporting state when the second limiting member 23 is inserted into the second limiting space 211 and abuts against the inner support member 22. Specifically, the second limiting member 23 is a rubber plug, and the second limiting space 211 is a through groove. When the sum of the extension dimensions of the support member 2 and the telescopic measuring member 3 is the same as the extension length of the railing, the rubber plug is inserted into the through groove to achieve the fixation of the outer support member 21 and the inner support member 22. By arranging the second limiting member 23 between the outer support member 21 and the inner support member 22, the inner support member 22 can be fixed to prevent the inner support member 22 from being retracted inward during measurement, resulting in inaccurate measurement results; by using the rubber plug as the second limiting member 23, the friction between the rubber plug and the inner support member 22 is large, and the fixing effect is good. As a convertible embodiment, the second limiting member 23 can also be a silicone pad or a bolt.

[0058] like Figure 4-Figure 5As shown, the telescopic measuring member 3 in this embodiment includes: an outer measuring member 31 having a hollow structure and having scales thereon; at least one inner measuring member 32 having scales thereon and being slidably disposed in the hollow structure of the outer measuring member 31, and having a fixed state in which the outer measuring member 31 is fixedly connected and a movable state in which the outer measuring member 31 is slidably connected. By fixedly connecting the outer measuring member 31 with the inner measuring member 32, the two ends of the telescopic measuring member 3 can be brought into contact between two adjacent railings, so as to facilitate measurement; by setting the outer measuring member 31 and the inner measuring member 32 to be relatively movable, the telescopic length of the telescopic measuring member 3 can be adjusted to match the spacing of the railings.

[0059] During specific measurement, the sum of the scales of the outer measuring piece 31 and the inner measuring piece 32 is the measured distance between the two railings.

[0060] like Figure 4-Figure 5 As shown, there are two inner measuring pieces 32, which are respectively arranged at the two ends of the outer measuring piece 31. By providing two inner measuring pieces 32, the telescopic length of the telescopic measuring piece 3 can be increased, and the measuring distance between two adjacent railings can be expanded. As a convertible embodiment, there can also be only one inner measuring piece 32, which is arranged at one end of the outer measuring piece 31, and the other end is closed.

[0061] like Figure 4-Figure 5 As shown, the outer measuring piece 31 is provided with a first limiting space 311; the telescopic measuring piece 3 includes: a first limiting piece 33, which cooperates with the first limiting space 311, and is suitable for the inner measuring piece 32 to be in a fixed state when the first limiting piece 33 is inserted into the first limiting space 311 and abuts against the inner measuring piece 32. Among them, the first limiting piece 33 is a spiral rubber plug, and the first limiting space 311 is a spiral groove. When the ends of the two inner measuring pieces 32 abut against the railing, the inner measuring piece 32 is fixed to the outer measuring piece 31 to measure the spacing of the railing. By setting the first limiting piece 33 between the outer measuring piece 31 and the inner measuring piece 32, the inner measuring piece 32 can be fixed to prevent the inner measuring piece 32 from being retracted inward when the telescopic measuring piece 3 is measuring, resulting in inaccurate measurement results; by using the spiral rubber plug as the first limiting piece 33, the friction between the spiral rubber plug and the inner measuring piece 32 is large, and the fixing effect is good. As a convertible implementation, the second limiting member 23 may also be a silicone pad or a bolt, or a common rubber plug.

[0062] like Figure 5As shown, a positioning member 34 is provided in the hollow structure of the outer measuring member 31, and the positioning member 34 is arranged relative to the first limiting space 311. When the inner measuring member 32 is in a fixed state, the positioning member 34 abuts against the inner measuring member 32. A positioning member 34 is provided on the inner side wall of the outer measuring member 31, and the positioning member 34 is arranged relative to the first limiting space 311. When the inner measuring member 32 is relatively fixed to the outer measuring member 31, the positioning member 34 abuts against the inner measuring member 32. Specifically, the positioning member 34 is a convex block, and the convex block is arranged on the inner side wall of the outer measuring member 31. By providing the positioning member 34, the inner measuring member 32 can be kept horizontally placed in a fixed state, and the inner measuring member 32 slides more smoothly in the hollow structure of the outer measuring member 31. As a convertible embodiment, it is also possible that the inner side wall of the outer measuring member 31 is smoothly arranged and matched with the side wall shape of the inner measuring member 32, and the positioning member 34 may not be provided.

[0063] like Figure 5 As shown, a partition 312 is provided in the hollow structure of the outer measuring piece 31, and two inner measuring pieces 32 are provided on both sides of the partition 312. Furthermore, the partition 312 is provided in the middle position of the hollow structure. By providing the partition 312 in the hollow structure, the inner measuring piece 32 can be limited to prevent the two ends of the inner measuring piece 32 from completely extending into the hollow structure and being difficult to take out. Specifically, the partition 312 is a partition, and the partition is fixedly connected to the inner side wall of the outer measuring piece 31. As a convertible embodiment, it is also possible that the length of each inner measuring piece 32 is greater than the length of the outer measuring piece 31, and then the partition 312 does not need to be provided.

[0064] Specifically, Figure 4-Figure 5 As shown, the scale at the position where the separator 312 is located on the outer measuring piece 31 is 0, and gradually increases towards both sides, and the scales at both ends are 3 cm; the scale at the end of the inner measuring piece 32 away from the separator 312 is the same as the scale at the end of the outer measuring piece 31, which is 3 cm, and gradually increases towards the position close to the separator 312, and the scale at the end close to the separator 312 is 7 cm. In order to fix the inner measuring piece 32 to the outer measuring piece 31, the maximum measurable size of the inner measuring piece 32 is 6.5 cm. Therefore, the measurable size range of both sides of the telescopic measuring piece 3 is 3 cm-6.5 cm.

[0065] When measuring the positioning of the railing, ensure that all inner measuring pieces 32 on the left side of the support 2 extend to the same length, and all inner measuring pieces 32 on the right side extend to the same length. When the inner measuring pieces 32 on the left side of the support 2 abut against the railing on the left side, since the inner measuring pieces 32 extend to the same length, the support 2 can be placed vertically. At the same time, since the inner measuring pieces 32 on the right side of the support 2 extend to the same length, the railing on the right side can be placed vertically, and the positioning is more accurate.

[0066] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
