DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or a middle element can be present at the same time. In contrast, when an element is referred to as "directly on" another element, no intermediate element is present.

[0022] Referring to Figures 1 to 4 A combined caliper includes a unit caliper 100 and a connecting sleeve 200, both ends of the unit caliper 100 are provided with annular convex columns 110, both ends of the connecting sleeve 200 are provided with annular grooves 210, the annular convex columns 110 can be embedded in the annular grooves 210; the inner wall of the unit caliper 100 is longitudinally provided with at least one pair of through guide grooves 120, the inner wall of the connecting sleeve 200 is longitudinally provided with a through transition groove 220, the transition groove 220 is arranged in one-to-one correspondence with the guide groove 120 and is transitionally connected.

[0023] The annular convex column 110 of the unit inclinometer pipe 100 can be embedded in the annular groove 210 of the connecting sleeve 200, so that two adjacent unit inclinometer pipes 100 can be spliced in sequence through the connecting sleeve 200, and the length can be spliced according to the required inclinometer hole depth to meet the inclinometer depth requirement. The transition groove 220 in the connecting sleeve 200 and the guide groove 120 in the unit inclinometer pipe 100 correspond to each other and are connected in transition, so that a through groove is formed for the smooth reciprocating sliding of the probe of the inclinometer, and the probe of the inclinometer will not be stuck or out of groove at the splicing position of the unit inclinometer pipe 100 and the connecting sleeve 200, and the inclinometer work is successfully completed. The structure design that the annular convex column 110 is embedded in the annular groove 210 not only makes the splicing more compact, but also prolongs the path length of the penetration of mud, concrete and the like, and the penetration path of the prior art is only in one direction, so it is easier to penetrate. The structure of the present application, the mud, concrete and the like penetrate first in one direction, and then change direction at the bottom of the annular groove 210, thereby better preventing the penetration of mud, concrete and the like.

[0024] Preferably, referring to Figure 1 , the guide grooves 120 of the unit inclinometer pipe 100 and the transition grooves 220 of the connecting sleeve 200 are respectively provided with two pairs and are uniformly distributed. In this way, the probe of the inclinometer is more convenient when put into the unit inclinometer pipe 100, and any one pair of oppositely arranged guide grooves 120 can be selected and put in.

[0025] Further, referring to Figures 1 to 4 , the connecting sleeve 200 is provided with an outer ring wall 230 and an inner ring wall 240, and the annular groove 210 is formed between the outer ring wall 230 and the inner ring wall 240. The end of the outer ring wall 230 protrudes from the end of the inner ring wall 240. In simple terms, the outer ring wall 230 is longer in length than the inner ring wall 240. The inner wall of the two ends of the unit inclinometer pipe 100 is formed with an inner stepped shoulder 130, and the outer wall of the two ends of the unit inclinometer pipe 100 is provided with an outer stepped shoulder 140; the outer ring wall 230 abuts against the outer stepped shoulder 140, and the inner ring wall 240 abuts against the inner stepped shoulder 130. The end of the outer ring wall 230 protrudes from the end of the inner ring wall 240, so that the outer ring wall 230 can first have a positioning effect on the annular convex column 110 of the unit inclinometer pipe 100, making it easier to insert into the annular groove 210. In addition, when the annular convex column 110 is inserted into the annular groove 210 until the end of the outer ring wall 230 abuts against the outer stepped shoulder 140, it indicates that the unit inclinometer pipe 100 and the connecting sleeve 200 are completely spliced in place, which plays a further positioning role.

[0026] Preferably, referring to Figure 3 , the inner wall of the outer ring wall 230 and the outer wall of the annular convex column 110 are in wedge-shaped structure matched and tightly wedged with each other, so that the splicing is more compact and does not need to be self-tapping.

[0027] More preferably, referring to Figure 1 , Figure 2 and Figure 4 , at least one pair of convex edges 150 are arranged on the outer wall of the unit inclinometer casing 100 longitudinally, and the convex edges 150 correspond to the guide grooves 120, and the guide grooves 120 are arranged on the inner wall of the unit inclinometer casing 100 corresponding to the convex edges 150. The guide grooves 120 are arranged at the positions corresponding to the convex edges 150, so that the thickness of the unit inclinometer casing 100 can be reduced, the cost can be saved, and the unit inclinometer casing 100 is more portable.

[0028] More preferably, referring to Figure 1 , the outer wall of the annular convex column 110 is provided with a convex 111, the convex 111 is transitionally connected with the convex edge 150, and the annular groove 210 at both ends of the connecting sleeve 200 is provided with a clamping groove 211 matched with the convex 111. That is, the convex 111 and the convex edge 150 are on a line, the convex 111 is matched with the clamping groove 211, and the clamping groove 211 plays a limiting role, so that the unit inclinometer casing 100 and the connecting sleeve 200 cannot move relative to each other, and the connection is more stable.

[0029] Specifically, referring to Figure 1 and Figure 2 , the outer wall of the connecting sleeve 200 is provided with a transition edge 250, and the transition edge 250 is arranged one by one corresponding to the convex edge 150. The clamping groove 211 is arranged at the position corresponding to the transition edge 250, so that the thickness of the connecting sleeve 200 can be reduced, and the cost can be saved.

[0030] More preferably, referring to Figure 3 , the depths of the guide grooves 120 at both ends are shallower than the depths of the guide grooves 120 in the middle, and the depth of the transition groove 220 is consistent with the depth of the guide grooves 120 at the ends. Specifically, the depths of the guide grooves 120 in the middle are the same, the depths of the guide grooves 120 at both ends gradually decrease, and the depth of the transition groove 220 is just the same as the depths of the guide grooves 120 at both ends. In this way, on the one hand, the thickness of the connecting sleeve 200 can be reduced, and the cost can be saved. On the other hand, when one end of the inclinometer probe reaches the end of the guide groove 120 or the transition groove 220, the other end of the inclinometer probe is still in the middle of the guide groove 120, so that it can be ensured that the inclinometer probe can slide smoothly and will not fall out.

[0031] Further, referring to Figure 4 , the combined inclinometer casing further comprises a cover 300, a bottom plate 310 and an annular side wall 320, and the annular side wall 320 can be embedded in the annular groove 210 at one end of the unit inclinometer casing 100. The inclinometer casing is formed by splicing a plurality of unit inclinometer casings 100 and connecting sleeves 200, the bottom of the inclinometer casing is sealed with a cover 300, which can effectively prevent mud, concrete and the like at the bottom of the inclinometer casing from entering the inclinometer casing. In addition, the end of the inclinometer casing is also sealed with a cover 300, which can effectively prevent gravel, soil and the like from falling from the end. When inclinometer work is needed, the cover 300 can be removed.

[0032] Preferably, the length of the unit inclinometer tube 100 is 2 meters or 4 meters.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
